FIELD OF THE DISCLOSURE

The present disclosure relates to the technical field of folding cabinets, and in particular to a folding connecting member, a folding supporting structure, and a folding cabinet.

BACKGROUND OF THE DISCLOSURE

Modern home life advocates for simplicity and aesthetic appeal. Minimalism is not only environmentally friendly and economical but also brings a simple, natural lifestyle to modern individuals accustomed to fast-paced work routines. Traditional wardrobes are typically non-detachable and non-foldable, making packaging, transportation, and storage extremely inconvenient. As a result, portable wardrobes have become common household items in contemporary home design. Currently, the structure of widely used, quick-assembly portable wardrobes often requires iron pipes combined with plastic connectors for assembly. The drawbacks of this structural design include: plastic connectors are prone to cracking and have poor structural stability; numerous scattered assembly parts make installation time-consuming and labor-intensive, resulting in low efficiency; there is inadequate strength of the assembled wardrobe; there are fixed compartmentalized storage spaces; and there is limited functionality in wardrobe usage.

Embodiment 1

Referring to FIGS. 1-11, the present embodiment provides a folding cabinet, and the folding cabinet comprises a folding supporting structure 1 and a folding enclosure structure 2 enclosed on a periphery of the folding supporting structure 1. Different from a traditional folding cabinet which is assembled by using scattered accessories, the folding supporting structure 1 and the folding enclosure structure 2 described in the present disclosure are integrated foldable structures, which realize rapid unfolding of an internal skeleton (i.e., the folding supporting structure 1) to achieve support, and convenient folding of an external cabinet panel (i.e., the folding enclosure structure 2) through unfolding and folding of an overall structure. Specifically, the folding supporting structure 1 comprises a first folding frame 11 configured to be rotatably unfolded and folded about a middle line of the first folding frame 11 as a rotating axis and two second folding frames 12 configured to be rotatably connected to two sides of the first folding frame 11. The first folding frame 11 and the two second folding frames 12 are rotated relative to each other to switch the folding supporting structure 1 between a storage state and an unfolded state.

The first folding frame 11 comprises three longitudinal rods extending in a height direction of the folding cabinet and arranged at intervals and four lateral rods 113 extending in a horizontal direction. The four lateral rods 113 are parallel to each other and connected between the three longitudinal rods. The three longitudinal rods are divided into two first longitudinal rods 111 located at two side positions of the first folding frame 11 and a second longitudinal rod 112 located at a middle position of the first folding frame 11. A first end of each of the four lateral rods 113 is fixedly connected to a corresponding one of the two first longitudinal rods 111, and a second end of each of the four lateral rods 113 is detachably connected to the second longitudinal rod 112 through a folding connecting member 115. The first folding frame 11 realizes a rotating unfolding and folding of the folding supporting structure 1 through the folding connecting members 115 symmetrically connected to a position of the middle line of the first folding frame 11. From a perspective of structural characteristics, the folding connecting member 115 in the unfolded state comprises a third port 1153 connected to the second longitudinal rod 112 in the height direction and two radial ports (i.e., second ports 1152) connected to corresponding two of the four lateral rods 113 on two sides of the folding connecting member 115 in the horizontal direction. Openings of the two radial ports are arranged facing away each other and are configured to be rotated and spliced to a connecting shaft 1156 to achieve a connection. The two second folding frames 12 are rotatably connected to an upper side and a lower side of the first folding frame 11 through supporting rods 114 on the first folding frame 11. Since a first end of each of the supporting rods 114 is rotatably connected to the first folding frame 11, a second end of each of the supporting rods 114 is connected to an insertion port 1241 on a connecting member 124 by insertion. The connecting member 124 abuts a long rod 122 of a corresponding one of the two second folding frames 12 to form the second folding frame 12. The connecting member 124 is a right-angle bent connecting member, and two rod connecting ends (i.e., defining the insertion port 1241) of the connecting member 124 are at a right angle. The connecting members 124 disposed on the two sides of the first folding frame 11 are connected to the long rod 122, and the long rod 122 is configured to support the first folding frame 11 to inhibit unfolding movement of the first folding frame 11. Since the two second folding frames 12 and the first folding frame 11 are connected together by the supporting rods 114, the first end of each of the supporting rods 114 is rotatably connected to a corresponding one of the two first longitudinal rods 111, and the second end of each of the supporting rods 114 is inserted into the insertion port 1241 on the connecting member 124. A rotating connection method allows the two second folding frames 12 and the first folding frame 11 to have a certain degree of freedom in unfolding and folding. However, as a skeletal support structure of the folding cabinet, a connection between the first folding frame 11 and the two second folding frames 12 needs to have a rigid structure. Obviously, the first folding frame 11 and the two second folding frames 12 need to be fixed in a relative position when the folding supporting structure 1 is unfolded. Therefore, the present disclosure provides a socket 1221 on a side of the long rod 122 for receiving a position-limiting rod 123. A first end of the position-limiting rod 123 is inserted into the socket 1221, and a second end of the position-limiting rod 123 is tightly matched with an insertion block 1150 on the folding connecting member 115 to achieve relative fixation between the first folding frame 11 and the two second folding frames 12.

The folding enclosure structure 2 is a plate assembly made of vacuum-formed material, which is lightweight, high-strength, and easy to carry. The plate assembly includes a back panel 21, side panels 22 rotatably connected to two sides of the back panel 21, and panels 23 pivotally connected to the side panels 22 through rotating shafts 202. The folding enclosure structure 2 encloses and surrounds the folding supporting structure 1 in the unfolded state, and pins at upper ends and lower ends of the rotating shafts 202 are inserted into and connected to shaft holes 1242 on the connecting members 124 at upper and lower positions of the folding supporting structure 1, so that the back panel 21 and the side panels 22 can be stably attached to three sides of the folding supporting structure 1, and the panels 23 can rotate around a position where the rotating shafts 202 are located to be opened and closed. End panels 31 are assembled on a top and a bottom of the folding cabinet, so that the folding cabinet is surrounded to form a closed space for storage. In addition, considering a need to effectively divide an internal space for placing items, the present disclosure is designed with protruding edges 201 extending along an enclosure direction (e.g., the horizontal direction) of the folding enclosure structure 2 and protruding inward, and a bottom of one or more partition boards 33 for placing the items is placed on the protruding edges 201. This not only allows a position of the one or more partition boards 33 to be flexibly distributed, but also has a low assembly cost and significantly improves assembly efficiency compared to a traditional method of fixing the one or more partition boards 33 with a bolt assembly structure in a traditional cabinet.

Embodiment 2

Referring to FIG. 4 and FIG. 6, the present embodiment provides a folding connecting member 115, and the folding connecting member 115 comprises a first supporting seat 1154 and a second supporting seat 1155 which are pivotally connected. The second supporting seat 1155 can be rotated relative to the first supporting seat 1154 to realize switching the folding connecting member 115 between a storage state and an unfolded state. Specifically, the first supporting seat 1154 and the second supporting seat 1155 each comprises an insertion block 1150, and the insertion block 1150 is located adjacent to ends of the first supporting seat 1154 and the second supporting seat 1155 that overlap. The ends of the first supporting seat 1154 and the second supporting seat 1155 are connected by a connecting shaft 1156. When the folding connecting member 115 is unfolded, the insertion blocks 1150 of the first supporting seat 1154 and the second supporting seat 1155 approach each other and extend outward, and movement of the insertion blocks 1150 is inhibited between the first supporting seat 1154 and the second supporting seat 1155 in an unfolding direction of the first supporting seat 1154 and the second supporting seat 1155. When the folding connecting member 115 is folded, the first supporting seat 1154 and the second supporting seat 1155 rotate toward each other along a pivot position to drive the insertion blocks 1150 to be retracted inward in a folding direction of the first supporting seat 1154 and the second supporting seat 1155.

The first supporting seat 1154 comprises a first port 1151, and the second supporting seat 1155 comprises a second port 1152. When the folding connecting member 115 is unfolded, an opening of the first port 1151 and an opening of the second port 1152 face away from each other. When the second supporting seat 1155 rotates and drives the second port 1152 to approach the first port 1151, the folding connecting member 115 is folded. In addition, the first supporting seat 1154 comprises a third port 1153 in a height direction of the first support, and the third port 1153 is perpendicular to and fixedly connected to the first port 1151. In the unfolded state, the first port 1151 of the first supporting seat 1154, the third port 1153, and the insertion block 1150 extending outward are perpendicular to each other. When the second supporting seat 1155 drives the second port 1152 to rotate about the connecting shaft 1156 as a rotating axis to enable the first port 1151 and the second port 1152 to face a same direction, the insertion block 1150 is retracted inward in a direction opposite to a rotation direction of the second supporting seat 1155, and the folding connecting member 115 is in a folded state.

Embodiment 3

Referring to FIGS. 4-8, a folding supporting structure 1 provided in the present embodiment comprises a first folding frame 11 configured to be rotated about a folding connecting member 115 as a rotating axis and two second folding frames 12 configured to be rotatably connected to two sides of the first folding frame 11. The first folding frame 11 and the two second folding frames 12 are rotated relative to each other to switch the folding supporting structure 1 between a storage state and an unfolded state.

The first folding frame 11 comprises three longitudinal rods and four lateral rods 113. The three longitudinal rods are parallel to each other and connected together through the four lateral rods 113. The three longitudinal rods are divided into two first longitudinal rods 111 located at two side positions of the first folding frame 11 and a second longitudinal rod 112 located at a middle position of the first folding frame 11. Ends portions of the second longitudinal rod 112 are connected to the four lateral rods 113 located on two sides of the second longitudinal rod 112 through a folding connecting member 115. Supporting rods 114 are rotatably connected to the two first longitudinal rods 111, an end of each of the supporting rods 114 away from the two first longitudinal rods 111 is connected to an insertion port 1241, and each of the supporting rods 114 is connected to the two second folding frames 12 through a connecting member 124.

Each of the two second folding frames 12 comprises a long rod 122 and a position-limiting rod 123, of which one end is inserted into the long rod 122. The long rod 122 is interlocked between a corresponding two of the supporting rods 114 to inhibit unfolding movement of the first folding frame 11. Two ends of the long rod 122 are connected to the connecting member 124. A side of the long rod 122 comprises a socket 1221 for receiving the position-limiting rod 123. A first end of the position-limiting rod 123 is inserted into the socket 1221, and a second end of the position-limiting rod 123 is tightly matched with a third radial port 1153 of the folding connecting member 115 to inhibit swinging movement of the two second folding frames 12 relative to the first folding frame 11.

The above is only a preferred specific implementation method of the present disclosure, but the design concept of the present disclosure is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present disclosure within the technical scope disclosed by the present disclosure shall be deemed to infringe the protection scope of the present disclosure.
