TECHNICAL FIELD

The present invention relates to the technical field of cable ties, and in particular to a cable tie.

BACKGROUND

A cable tie, also known as a zip tie, a hose tie and a wire tie, is a tie for bundling things. According to materials, cable ties can be generally divided into nylon cable ties, stainless steel cable ties and plastic-sprayed stainless steel cable ties; and according to functions, there are a great variety of cable ties, such as ordinary cable ties, retractable cable ties, label cable ties, fixed lock type cable ties, bolt type cable ties and heavy pull cable ties. The cable ties have been widely for bundling articles in Christmas gift factories, electronics factories, wire processing factories, wires and cables, toy factories, festive festivals, stationery stores, fresh food supermarkets, residential daily necessities, electrical appliances and connectors. The cable tie usually includes a tie body and a locking head, the locking head has an elastic sheet, the elastic sheet is provided with locking teeth, and a row of teeth are integrally formed on an outer wall of one side of the tie body. During use, the tie body passes through the locking head, so that the elastic sheet engages the locking teeth with the teeth under the action of the own elastic force, and the tie body can be stopped from retreating and be fixed. However, the cable tie has the following shortcomings:

One side of the tie body is provided with the teeth and the other side is usually in a plane state, so after the cable tie is locked, only the teeth on one side of the tie body are stressed to prevent loosening, and the single row of teeth are engaged with a large force, which is prone to cause the teeth to break;

• • the teeth are arranged on the single side of the tie body, so the thickness of the tie body is non-uniform, and the tie body at the adjacent teeth is easy to break during bundling; and
  • the teeth are arranged on the single side of the tie body, so unhooking and slipping will occur when the teeth are away from the locking teeth and the tie body is shaken by an external force, resulting in loose bundling. In view of the above problems, the inventor proposed a cable tie for solving the above problems.

When the tie body penetrates through the locking head, the tie body is in contact with the locking teeth through the outer guide surface and the inner guide surface, and the inner guide surface is guided by the inclined surface to push the elastic block, so that the elastic block slides into the storage cavity, which is convenient for the tie body to pass through. After bundling, the elastic block pushes the tie body by the own elastic force, so that the movable teeth are engaged with the inner teeth. Meanwhile, the tie body is pushed by the elastic block to be close to the fixed teeth, and the fixed teeth are engaged with the convex teeth, so that two surfaces can be engaged and stressed. Stress on the two sides can reduce the stress of a single tooth, thereby avoiding tooth breakage. Engagement on the two sides can avoid the loosening of the teeth caused by the pulling of the tie body, thereby improving the bundling fastness.

Furthermore, the teeth on the two sides of the tie body partially overlap, so that the overall thickness of the tie body is uniform, thereby enhancing the strength of the overall tensile stress, preventing the tie body at the tooth spacing from being broken during bundling and bending, and improving the durability.

Embodiments: as shown in FIG. 1 to FIG. 7, the present invention provides a cable tie, including a locking head 1 and a tie body 2, where two ends of an inner cavity of the locking head 1 respectively form an extend-in opening 12 and a pull-out opening 11, one end of the tie body 2 is fixedly connected to an outer wall of one end of the locking head 1 close to the extend-in opening 12, tie teeth 3 are fixedly arranged on outer walls of two sides of the tie body 2, tooth surfaces of the tie teeth 3 on the two sides of the tie body 2 at the same section partially overlap in a thickness direction of the tie body 2, locking teeth 4 are mounted on inner walls of two sides of the locking head 1, the locking teeth 4 are matched with the tie teeth 3, and an extend-out head 5 is integrally formed at one end of the tie body 2 away from the locking head 1.

By the above technical solution, the tie teeth 3 are arranged on the outer walls of the two sides of the tie body 2 and are combined with the locking teeth 4 arranged on the inner walls of the two sides of the locking head 1, so that during bundling, the tie body 2 extends the extend-out head 5 from the extend-in opening 12 and pulls the extend-out head out of the pull-out opening 11, the tie body 2 penetrates through the locking head 1 to bundle articles, and at this time, the tie teeth 3 on the two sides of the tie body 2 are engaged with the locking teeth 4 to stop the tie body 2 from retreating. Due to the tie teeth 3 on the two sides, the overall thickness of the tie body 2 is uniform, and the tie body 2 is prevented from being broken during bundling and bending. Stress on the two sides reduces the stress of a single tooth, thereby preventing the teeth from being broken. Engagement on the two sides can prevent the teeth from loosening when the tie body 2 is pulled, thereby improving the bundling fastness.

Further, the outer wall of the locking head 1 is of a square platform structure, a big end of the square platform structure is close to the extend-in opening 12, and an inner wall of the locking head 1 at the extend-in opening 12 is provided with a guide rounded corner.

By the above technical solution, the square platform structure is convenient for the tie body 2 to penetrate through the locking head 1, and the rounded corner arranged at the extend-in opening 12 is convenient for the tie body 2 to extend in and avoid the abrasion of the tie teeth 3.

Further, the tie teeth 3 include convex teeth 31, a plurality of convex teeth 31 are integrally formed on an outer wall of one side of the tie body 2 close to the pull-out opening 11, a groove 32 is formed in an outer wall of the other side of the tie body 2, a plurality of inner teeth 33 are fixedly mounted on an inner wall of the groove 32, the convex teeth 31 and the inner teeth 33 are all matched with the locking teeth 4, a bending groove 34 is formed at one end of the groove 32 close to the locking head 1, the convex teeth 31 and the inner teeth 33 are of asymmetric structures along the two sides of the tie body 2, and tooth surfaces of the convex teeth 31 and the inner teeth 33 at the same section partially overlap in the thickness direction of the tie body 2.

By the above technical solution, the tensile strength of the tie teeth 3 is improved through the engagement on two sides of the convex teeth 31 and the inner teeth 33; and the inner teeth 33 are not arranged at the bending groove 34, which is convenient for the tie body 2 to pass through the bending groove 34 to bend inward so as to penetrate through the locking head 1.

Further, one surface of each of the convex teeth 31 away from the locking head 1 forms an outer guide surface 311 with an inclined structure, one surface of each of the convex teeth 31 close to the locking head 1 forms an outer stop surface 312, one side of each of the convex teeth 31 away from the tie body 2 is provided with an outer platform 313, and the outer wall of the tie body 2 between the two adjacent convex teeth 31 forms an outer flat groove 314; one surface of each of the inner teeth 33 away from the locking head 1 forms an inner guide surface 331 with an inclined structure, one surface of each of the inner teeth 33 close to the locking head 1 forms an inner stop surface 332, one side of each of the inner teeth 33 away from the tie body 2 is provided with an inner platform 333, and the outer wall of the tie body 2 between the two adjacent inner teeth 33 forms an inner flat groove 334; and the convex teeth 31 and the inner teeth 33 are uniformly distributed in a length direction of the tie body 2, the length of the outer platform 313 is the same as that of the inner flat groove 334, the outer platform 313 faces the inner flat groove 334, the outer guide surface 311 overlaps with the inner stop surfaces 332 on two sides of the inner platform 333 and the tooth surface at the inner guide surface 331, and the outer flat groove 314 overlaps with the tooth surface of the inner guide surface 331 close to one end of the inner flat groove 334.

By the above technical solution, when the tie body 2 penetrates through the locking head 1, the outer guide surface 311 and the inner guide surface 331 are in contact with the locking teeth 4, so that the locking head 1 is penetrated through inclined guidance. After bundling, the locking teeth 4 are engaged at the outer flat groove 314 and the inner flat groove 334. At this time, the outer stop surface 312 and the inner stop surface 332 are attached to the locking teeth 4 for limitation, thereby stopping from retreating. Through the stress of the teeth on the two sides of the tie body 2, the tensile strength is improved, the stress of the single tooth is reduced, and the breakage of the tie teeth 3 is avoided. The convex teeth 31 and the inner teeth 33 are uniformly distributed in a length direction of the tie body 2, the length of the outer platform 313 is the same as that of the inner flat groove 334, the outer platform 313 faces the inner flat groove 334, the outer guide surface 311 overlaps with the inner stop surfaces 332 on two sides of the inner platform 333 and the tooth surface at the inner guide surface 331, and the outer flat groove 314 overlaps with the tooth surface of the inner guide surface 331 close to one end of the inner flat groove 334, so the convex teeth 31 and the inner teeth 33 in the length direction of the tie body 2 are different from each other up and down, which are not complementary and are asymmetrical. Furthermore, the teeth on the two sides of the tie body 2 partially overlap, so that the overall thickness of the tie body 2 is uniform, thereby enhancing the strength of the overall tensile stress, avoiding the tie body 2 at the tooth spacing from being broken during bundling and bending, and improving the durability.

Meanwhile, the tie body 2 is pushed by the elastic block 42 to be close to the fixed teeth 41, and the fixed teeth 41 are engaged with the convex teeth 31, so that two surfaces can be engaged and stressed. Stress on the two sides can reduce the stress of a single tooth, thereby avoiding tooth breakage.

Due to the tie teeth 3 on the two sides, the overall thickness of the tie body 2 is uniform, and the tie body 2 is prevented from being broken during bundling and bending. Stress on the two sides reduces the stress of a single tooth, thereby preventing the teeth from being broken. Engagement on the two sides can prevent the teeth from loosening when the tie body 2 is pulled, thereby enabling the bundling more stable.

In addition, the bending portion 6 is arranged between the locking head 1 and the tie body 2, and the extending direction of the bending portion 6 is inclined to the extending direction of the tie body 2, so that during bundling, the bending portion 6 can be close to the outer surface of the article to reduce the gap between the cable tie and the article, thereby preventing the article from slipping away from the fixing cavity 7 and enabling the bundling more stable.

Further, a triangular guide portion 52 is formed at one end of the extend-out head 5 away from the locking head 1, and the width of the guide portion 52 increases from one end away from the locking head 1 to one end close to the locking head 1. In this way, the width of a front end of the guide portion 52 is smaller, thereby facilitating the alignment of the guide portion 52 and the extend-in opening 12 and facilitating a user to extend the guide portion 52 into the extend-in opening 12.

Specifically, referring to FIG. 12 to FIG. 15, FIG. 14 shows that the locking head 1 has a first fixing surface 13 facing the fixing cavity 7, the bending portion 6 has a second fixing surface 61 facing the fixing cavity 7, and the tie body 2 has a third fixing surface 21 facing the fixing cavity 7.

In this way, a transition area between the second fixing surface 61 and the first fixing surface 13 can be smoother and the bending can be reduced, or a transition area between the second fixing surface 61 and the third fixing surface 21 can be smoother and the bending can be reduced, so that the first fixing surface 13, the second fixing surface 61 and the third fixing surface 21 can cling to the outer surface of the article, thereby preventing the article from slipping away from the fixing cavity 7, and enabling the bundling more stable.

Specifically, the outer wall of the locking head 1 is of a square platform structure, the locking head 1 further has a first side surface 14 connected to the first fixing surface 13, the first side surface 14 is located on one side of the locking head 1 away from the bending portion 6, and the extend-in opening 12 is located at the joint of the first fixing surface 13 and the first side surface 14. In this way, the extend-in opening 12 is closer to the first fixing surface 13; and when the article is bundled, the tie body 2 on one side of the extend-in opening 12 is closer to the article, thereby preventing the article from slipping away from the fixing cavity 7 and enabling the bundling more stable.

Further, the locking head 1 further has a second side surface 15 opposite to the first side surface 14, the pull-out opening 11 is located on the second side surface 15, and the inner cavity of the locking head 1 extends along a straight line. In this way, an included angle between the length extending direction of the inner cavity of the locking head 1 and the first fixing surface 13 is smaller; and when the article is bundled, the tie body 2 on one side of the extend-in opening 12 is closer to the article, thereby preventing the article from slipping away from the fixing cavity 7 and enabling the bundling more stable.

The tie teeth 3 are set as the inner teeth 33, so that the tie teeth 3 can be prevented from protruding out of the outer surface of the tie body 2 and hurting hands, thereby avoiding the influence on the use experience feeling. The inner teeth 33 on the two sides of the tie body 2 in the thickness direction are staggered in the length direction of the tie body 2, so that the tie teeth 3 on the two sides can be separated from the locking teeth 4 in the locking head 1 when be stressed, thereby enabling the bundling more stable.

It may be understood that in other embodiments, regardless of whether the tie teeth 3 protrude from the outer surface of the tie body 2 to hurt hands, the tie teeth 3 may also be set as convex teeth, and at this time, the tie teeth 3 on the two sides of the tie body 2 are convex teeth, or the tie teeth 3 on the two sides of the tie body 2 are respectively inner teeth 33 and convex teeth, which are still within the protection scope of the present invention.

Referring to FIG. 11 and FIG. 14, specifically, a bending groove 34 is formed at one end of the groove 32 close to the locking head 1, and the bending groove 34 extends from one end of the tie body 2 close to the bending portion 6 to the bending portion 6 and the locking head 1 sequentially. The bending groove 34 is not provided with the tie teeth 3, and the thickness of the cable tie at the corresponding position of the bending groove 34 is reduced, which is convenient for the cable tie to pass through the bending groove 34 to bend inward so as to penetrate through the locking head 1.

Further, referring to FIG. 15, one surface of each of the inner teeth 33 away from the locking head 1 forms an inner guide surface 331 with an inclined structure, one surface of each of the inner teeth 33 close to the locking head 1 forms an inner stop surface 332, and the outer wall of the tie body 2 between the two adjacent inner teeth 33 forms an inner flat groove 334.

In addition, due to the arrangement of the elastic block 42, a user can operate the elastic block 42 to rotate relative to a side wall of the inner cavity of the locking head 1, so that the engagement between the movable teeth 43 and the inner teeth 33 can be released, and the tie body 2 can slide in the inner cavity of the locking head 1 under the action of an external force.

Referring to FIG. 16 to FIG. 28, the embodiments of the present invention provide a cable tie. The cable tie is used to bundle articles.

Referring to FIG. 16 to FIG. 21, the cable tie includes a locking head 1 and a tie body 2 which are connected with each other, where two ends of an inner cavity of the locking head 1 respectively form an extend-in opening 12 and a pull-out opening 11, the tie body 2 is provided with tie teeth 3, the inner cavity of the locking head 1 is provided with locking teeth 4 matched with the tie teeth 3, and one end of the tie body 2 can extend into the extend-in opening 12, so that a fixing cavity 7 for fixing articles is surrounded by the locking head 1 and the tie body 2.

According to the cable tie 2 in the embodiments of the present invention, when the tie body enters the inner cavity of the locking head 1 from the extend-in opening 12 in the length direction of the tie body, the small end 35 and the big end 36 of each of the tie teeth 3 enter sequentially to be engaged with the locking teeth 4; and since the width of the tie teeth 3 increases from the small end 35 to the big end 36, the gradually increasing width plays a guiding role, so that the tie body 2 can enter the locking head 1 more smoothly, and it is more labor-saving for the user to pull the tie body 2.

In addition, the tie teeth 3 extend approximately in the length direction of the tie body 2, and the tie teeth 3 are similar to reinforcing ribs and play a protective role when the tie body 2 is subjected to an external force in a cross-section direction, so that the breakage of the section of the tie body 2 can be effectively avoided.

Specifically, the V-shaped teeth 37 are located on the surface of one side of the tie body 2 facing the fixing cavity 7, and the elastic block 42 is located on the side wall of the inner cavity of the locking head 1 close to the tie body 2. In this way, when the article is bundled by the cable tie, the V-shaped teeth 37 are in contact with the article, so that a friction force between the tie body 2 and the article is increased, and the article can be bundled by the cable tie more stably.

Continuously referring to FIG. 13, the extending direction of the inner cavity of the locking head 1 is perpendicular or approximately perpendicular to the length extending direction of the tie body 2, so that in the production process of the cable tie, the formed cable tie is easier to be separated from a mold, and the production cost is reduced.

Due to the tie teeth 3 on the two sides, the overall thickness of the tie body 2 is uniform, and the tie body 2 is prevented from being broken during bundling and bending. Stress on the two sides reduces the stress of a single tooth, thereby preventing the teeth from being broken.
