Description

Technical Field

[0001] This instruction manual pertains to the field of household products, and in particular to a zipper. Background Technology

[0002] Zippers are common components used in clothing in daily life, typically consisting of teeth, a slider, top and bottom stops, or locking mechanisms. Zippers have also evolved into various types depending on the clothing application. However, the connection between the handle and zipper pull in common everyday clothing is usually quite simple. The handle has a large gap in both the horizontal and vertical directions at the connection point, allowing it to move freely and accompanied by noise. During activities like running, gymnastics, and yoga, the free movement of the zipper and the resulting noise can often create a negative experience for the user.

[0003] In existing technologies, the aforementioned technical problem is solved by clamping the connecting part of the zipper head on both sides of the zipper handle, preventing the handle from moving freely on the zipper head. For example, a zipper pull and zipper disclosed in 201810007836.2 provide such a solution. However, in these solutions, the zipper head structure is complex, the manufacturing process is extensive, and dimensional errors are significant. Therefore, providing a simple, low-cost, and non-swaying zipper for motion is a pressing technical problem that needs to be solved in this field. Utility Model Content

[0004] The purpose of this specification is to provide a zipper for clothing that prevents shaking and noise during user movement, thereby improving the user experience.

[0005] This specification provides a zipper including a zipper head and a handle. The handle includes a gripping part, a connecting crossbar, and a clamping part. The clamping part includes a left clamping part and a right clamping part that correspond to each other. The zipper head includes a zipper head body and a connecting part. The handle is rotatably connected to the connecting part through the connecting crossbar. The connecting part is provided with a through hole, and the connecting crossbar passes through the through hole with a diameter larger than the diameter of the through hole. The left and right clamping parts are provided on the left and right sides of the connecting part and have a longitudinal gap with the connecting part, but do not contact it.

[0006] Preferably, the handle has an opening formed by the connecting crossbar and the clamping portion.

[0007] Preferably, the connecting part is arc-shaped, and the connecting part is a complete arc without any gaps or openings on the circumference. The connecting part and the zipper head body are manufactured by integral molding, and there is no opening between them.

[0008] Preferably, the connection between the gripping part and the left and right clamping parts is arc-shaped, there is a certain angle between the gripping part and the left and right clamping parts, and the handle is curved.

[0009] Preferably, the length of the clamping portion is less than the length of the gripping portion.

[0010] Preferably, the upper and lower surfaces of the grip portion are provided with anti-slip patterns.

[0011] Preferably, the zipper head is a metal zipper head, and the handle is an injection-molded handle.

[0012] Preferably, the zipper head is an injection-molded zipper head, and the handle is an injection-molded handle.

[0013] The zipper provided in this embodiment employs a design where the size of the handle connecting bar is slightly larger than the size of the zipper head connecting hole, creating an interference fit. This prevents the handle connecting bar from moving freely within the zipper head connecting hole, allowing it to move only when the user applies significant manual force. This effectively prevents the handle from wobbling on the zipper head, avoiding the user's discomfort from zipper jumping and noise during movement. This technical solution features a simple structure, low cost, fewer processing steps, and is less prone to dimensional errors. Attached Figure Description

[0017] Among them, 1-zipper head body, 2-connecting part, 3-grip part, 4-connecting crossbar, 5-clamping part, 6-gap. Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments in this specification, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0019] like Figure 1-2 As shown in the figure, this specification provides a zipper including a zipper head and a handle. The handle includes a gripping part 3, a connecting crossbar 4, and a clamping part 5. The clamping part 5 is divided into a left clamping part and a right clamping part that correspond to each other. The zipper head includes a zipper head body 1 and a connecting part 2. The handle is rotatably connected to the connecting part 2 via the connecting crossbar 4. The connecting part 2 is provided with a through hole, through which the connecting crossbar 4 passes, and the diameter of the connecting crossbar 4 is larger than the diameter of the through hole. The left and right clamping parts 5 are provided on the left and right sides of the connecting part 2 and are provided with a gap 6 in the longitudinal direction between them. Neither the left nor the right clamping parts 5 are in direct contact with the connecting part 2.

[0020] The zipper pull has an opening formed by the connecting crossbar 4, left and right clamping parts 5, and the top of the gripping part 3. The connecting part 2 is arc-shaped and is a complete, uninterrupted arc shape. The connecting part 2 and the zipper head body 1 are manufactured as a single piece, without any openings or breaks between them. The through hole in the connecting part 2 is machined in one step during production, achieving high dimensional accuracy.

[0021] In one embodiment, the connection between the gripping part 3 and the left and right clamping parts 5 is arc-shaped, and there is a certain angle between the gripping part 3 and the left and right clamping parts 5, so that the handle is curved.

[0022] In one embodiment, the length of the clamping part 5 is shorter than the length of the gripping part 3. The longer length of the gripping part 3 makes it easier for the user to hold and improves the user experience.

[0023] In one embodiment, the upper and lower surfaces of the grip portion 3 are provided with anti-slip patterns to increase the friction of the grip portion 3 and provide convenience for the user.

[0024] In one embodiment, the zipper head is a metal zipper head, and the handle is an injection-molded handle.

[0025] In one embodiment, the zipper head is an injection-molded zipper head, and the handle is an injection-molded handle.

[0026] This utility model provides a zipper that improves the design between the connecting crossbar of the handle and the connecting part of the zipper head. The diameter of the connecting crossbar is slightly larger than the diameter of the through hole in the connecting part, achieving an interference fit and significantly increasing the friction of the connecting part. When the zipper is not in use, i.e., when the user does not apply significant external force, the damping between the connecting crossbar and the connecting part is sufficient to prevent relative movement between the handle and the zipper head, thus eliminating noise. This embodiment abandons the design method of providing friction through the contact friction between the handle clamping part and the zipper head connecting part. This simplifies the product structure and greatly simplifies the production steps of the zipper head. The connecting part and the zipper head body are integrally molded during production, which also improves the dimensional accuracy of the through hole in the connecting part. The simple structure and fast production greatly save manpower and resources.

[0027] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on its differences from other embodiments.
