Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to the field of leisure sports goods, and in particular to a golf bag.

Description of Related Art

The top of a golf bag is provided with an outer frame for people to lift the golf bag, and a handle is provided on the outer frame. People drag the entire golf bag by the handle. Due to many factors in the external environment, there is a certain degree of inevitable bumps when carrying the golf bag, resulting in different degrees of collision of the golf bag. At present, since the outer frame of the golf bag and the handle thereof are locked with each other, there is no buffer space on the handle when carrying the golf bag, and the golf bag is easily collided with a large impact during the dragging process, resulting in wear and damage to the golf bag, which is inconvenient for people to use and has poor practicality.

To solve the above technical problem, the patent document with the authorization announcement number CN211935458U discloses an anti-collision frame structure of a golf bag. The anti-collision frame structure includes a head frame and a hand-held portion. A first attachment portion and a second attachment portion which are symmetrical to each other are provided on both sides of the head frame, respectively, and the first attachment portion and the second attachment portion are each provided with an attachment hole. Connecting blocks matching the attachment holes are provided on both ends of the hand-held portion, respectively, and the connecting blocks are provided with sliding grooves. The hand-held portion can be slidably clamped in the attachment holes of the first attachment portion and the second attachment portion through the connecting blocks, and the first attachment portion and the second attachment portion are each provided with an anti-falling screw penetrating in the sliding groove. According to the patent document, the handle fixed on the traditional outer frame is designed as a telescopic structure, and thus a buffer space is formed between the outer frame and the hand-held portion, which can effectively avoid collision during dragging and reduce a collision impact force of the golf bag, thereby achieving the effect of protecting the golf bag.

In the patent document, the anti-falling screw can move along the sliding groove, and when the hand-held portion is collided during dragging, the hand-held portion can be retracted into the outer frame. In this way, relative to the outer frame, the hand-held portion has only two stop positions, one of which is when the anti-falling screw is at one end of the sliding groove, the hand-held portion is in an extended state. The other position is when the anti-falling screw is at the other end of the sliding groove, the hand-held portion is in a retracted state.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is to enable the hand-held portion to stop at a plurality of positions with respect to a head frame main body, so as to facilitate a user to adjust the position of the hand-held portion by himself/herself.

To solve the above technical problem, the present invention provides the following technical solutions. A head frame with a telescopic handle, the head frame including: a head frame main body; and a handle, in which a female plug structure is fixed on a side wall of the head frame main body, the handle is U-shaped, and a male plug structure is provided at an end portion of the handle, the male plug structure is provided with a strip-shaped groove, and the female plug structure is provided with a fastening hole, a matching fastening bolt is provided in the fastening hole, and the fastening bolt is located in the strip-shaped groove, the male plug structure is provided with a plurality of limit slots, which are distributed along a length direction of the male plug structure, and the female plug structure is provided with an elastic piece, which is capable of matching any of the limit slots.

With respect to the head frame main body, a user pulls out or retracts the handle, and the male plug structure moves relative to the female plug structure. According to an amount of movement of the male plug structure relative to the female plug structure, the elastic piece passes over a certain number of limit slots and finally matches one of the limit slots, and the handle is initially positioned on the head frame main body. Then, the user tightens the fastening bolt, which causes the female plug structure to clamp the male plug structure, thereby fixing the position of the handle on the head frame main body.

The female plug structure and the male plug structure are both hollow and flat. When the user tightens the fastening bolt, the flat structural design facilitates large-area contact between the female plug structure and the male plug structure. Further, the hollow male plug structure can be elastically deformed, and resilience thereof can cause an outer side wall of the male plug structure to come into close contact with an inner side wall of the female plug structure, which facilitates a fixed connection between the female plug structure and the male plug structure.

The limit slots are provided at a bottom portion of the male plug structure and have a tooth shape, and the elastic piece is provided with a tooth-shaped protrusion matching the limit slot. In a case where the male plug structure moves relative to the female plug structure, the tooth-shaped protrusion of the elastic piece is forced to undergo elastic deformation when leaving the matching limit slot, and then, when the tooth-shaped protrusion is aligned with another limit slot, the tooth-shaped protrusion is reset and matches that limit slot.

The elastic piece includes a pair of U-shaped structures, and openings of the pair of U-shaped structures are disposed opposite to each other. The tooth-shaped protrusion is connected to the pair of U-shaped structures and located above the pair of U-shaped structures, and the elastic piece is formed by bending a strip-shaped elastic piece. A ridge-shaped groove extending into the female plug structure is provided on an inner side wall of the head frame main body, and the elastic piece is embedded in the female plug structure through the ridge-shaped groove.

An auxiliary sleeve structure is provided on the side wall of the head frame main body. The auxiliary sleeve structure and the female plug structure are aligned front and back and have a certain distance therebetween, and the male plug structure passes through the auxiliary sleeve structure and is inserted into the female plug structure. The auxiliary sleeve structure facilitates a stable connection between the male plug structure and the head frame.

According to the head frame with a telescopic handle of the present invention, the limit slots match the elastic piece, which provides a mechanical feel when adjusting the position of the handle, and can synchronously position the male plug structures at both ends of the handle to avoid a difference in a telescopic range at both ends of the handle. The fastening bolt can fix the handle at a position required by the user.
