Description

Technical Field

[0001] The utility model relates to the field of zippers, in particular to a double-pull-tab self-locking zipper head. Background Art

[0002] Zippers are important accessories in the clothing industry. Double-sided zipper heads can be operated from both ends of the zipper. Double-sided zipper heads are mainly used on double-sided clothing or tents. Double-sided zipper heads include a zipper body and a zipper head. To achieve the locking function, a horse hook and a spring are added to the zipper head. The horse hook is rotatably connected to the zipper head through a pin, and the user controls the movement of the horse hook through a pull tab during use. This type of zipper head requires tweezers and other tools to assemble the tiny spring and pin, and the overall assembly process is very inconvenient. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0021] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0022] See also Figure 1-3The utility model provides a double pull-tab 2 self-locking zipper head, including a slider body 1 and two pull-tabs 2. A chain plate 11 is arranged inside the slider body 1. The slider body 1 has a cavity for accommodating the passage of the zipper. A positioning hole 12 and a linkage hole 13 are arranged on the upper surface of the slider body 1. The positioning hole 12 is connected to the cavity. The linkage hole 13 passes through the chain plate 11. The upper and lower surfaces of the slider body 1 are connected through the linkage hole 13. An upper cap 3 and a lower cap 4 are fixed to the upper and lower side surfaces of the slider body 1, respectively. The upper cap 3 and the lower cap 4 are divided into two parts. A large hook 32 and a small hook 41 are separately provided, and a spring piece 33 is also provided in the upper cap 3. A positioning hook 321 and a linkage rod 322 are provided on the large hook 32. The positioning hook 321 is arranged in the positioning hole 12, and the linkage rod 322 is arranged in the linkage hole 13. A linkage hook 411 is provided on the small hook 41, and the linkage hook 411 is kept hooked with the linkage rod 322. A pivot 21 is provided at one end of the pull tab 2, and the two pivots 21 are respectively located between the large hook 32 and the slider body 1 and between the small hook 41 and the slider body 1. When the user is in use, the pull tab 2 on the upper surface of the slider body 1 can drive the large hook 32 to move upward, and the pull tab 2 on the lower surface of the slider body 1 pulls the small hook 41, and the linkage hook 411 on the small hook 41 pushes the linkage rod 322, thereby realizing the upward movement of the positioning hook 321 on the large hook 32. The above two methods can realize the movement of the positioning hook 321 to release the fixation of the positioning hook 321 to the zipper. After the external force is removed, the spring piece 33 pushes the large hook 32 to move downward, thereby realizing the self-locking effect of the zipper head.

[0023] When assembling the zipper head, the pull tab 2, the large hook 32, and the upper cap 3 are sequentially installed on the upper surface of the slider body 1, and then the pull tab 2, the small hook 41, and the lower cap 4 are sequentially installed on the lower surface of the slider body 1. It should be noted that during the installation, the linkage hook 411 of the small hook 41 and the linkage rod 322 of the large hook 32 should be in the same position as the slider body 1. Figure 5 In the hooking position shown, the product structure eliminates the small spring and latch through the spring piece 33, which reduces the material cost of the product and makes assembly easier. Since the spring is eliminated, the zipper head can avoid the situation where the paint is stuck to the spring during subsequent surface treatment such as painting, ensuring the normal use of the zipper head.

[0024] like Figure 1 , 4As shown, an upper annular fixed edge 14 and a lower annular fixed edge 15 are respectively provided on the upper and lower surfaces of the slider body 1, the upper cap 3 and the lower cap 4 are respectively fixed on the upper and lower annular fixed edges 15, the large horse hook 32 and the small horse hook 41 are respectively arranged in the upper annular fixed edge 14 and the lower annular fixed edge 15, the positioning hole 12 is arranged in the upper annular fixed edge, and the linkage hole 13 connects the inner cavity of the upper annular fixed edge 14 and the lower annular fixed edge 15.

[0025] like Figure 1 , 4 As shown, the upper annular fixed edge 14 is provided with an upper paving groove 141 , the lower annular fixed edge 15 is provided with a lower paving groove 151 , and the two pivots 21 are respectively located in the upper paving groove 141 and the lower paving groove 151 .

[0026] As shown in the figure, two fixed bosses 34 are arranged at intervals in the upper cap 3 , and two ends of the spring piece 33 are provided with snap-fitting grooves 331 , and the snap-fitting grooves 331 are snap-fitted to the fixed bosses 34 .

[0027] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
