Description

Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to an anti-clamping zipper. Background Art

[0002] At present, the common pain points in the use of zippers are as follows: when the slider in the zipper is pulled on the chain tape, the inner lining of the clothing is easily caught between the slider and the teeth, and this phenomenon will cause a blocking problem between the slider and the teeth, making it difficult to continue pulling the slider. Summary of the Utility Model

[0003] The utility model provides an anti-clamping zipper, which solves the above problems existing in the prior art during use.

[0004] The technical solution of the utility model is realized as follows: an anti-clamping zipper includes two chain tapes. On one end of the chain tapes close to each other, teeth are fixedly arranged, and on one end of the chain tapes far from each other, stoppers are fixedly arranged. A limiting mechanism is arranged on the chain tape, and the limiting mechanism is used to prevent the stopper from swinging towards the direction of the teeth.

[0005] The utility model is further arranged as follows: on one side of the chain tape, a first fabric layer and a second fabric layer are sequentially arranged. One ends of the first fabric layer and the second fabric layer close to the teeth are fixedly arranged on the chain tape by sewing, and the stopper is fixedly arranged between the first fabric layer and the second fabric layer by sewing.

[0006] The utility model is further arranged as follows: the stopper is made of flexible rubber.

[0007] The utility model is further arranged as follows: the limiting mechanism includes a metal fixing member fixedly arranged on the chain tape. The metal fixing member is in a "U" shape, the middle part of the metal fixing member penetrates the chain tape, and both ends of the metal fixing member extend towards the direction far from the teeth and are respectively clamped on the outer sides of the chain tape and the second fabric layer.

[0008] The utility model is further arranged as follows: a plurality of the metal fixing members are arranged on the chain tape at intervals from top to bottom.

[0009] The utility model is further arranged as follows: an auxiliary piece extends in the middle of the stopper, and one end of the auxiliary piece close to the teeth is used to abut against the end of the metal fixing member. The auxiliary piece and the stopper are integrally formed.

[0010] The utility model is further arranged as follows: a reinforcing rib is arranged between the included angle of the auxiliary piece and the stopper. The reinforcing rib, the auxiliary piece and the stopper are integrally formed.

[0011] In summary, the beneficial effects of the utility model are as follows:

[0012] 1. With this feature, the flap is used to cover the lining of the garment, thereby preventing the lining from being caught in the zipper pull and preventing the zipper from getting stuck by the lining during use.

[0013] 2. The metal fasteners are arranged at intervals on the chain belt. On the one hand, this can improve the limiting effect of the metal fasteners on the baffles, and on the other hand, it does not hinder the natural bending of the chain belt.

[0014] 3. When the auxiliary piece abuts against the metal fastener, the reinforcing rib is used to maintain a certain angle between the baffle and the auxiliary piece, further pressing the baffle onto the lining of the garment. Attached Figure Description

[0019] The following will refer to the appendix in the embodiments of this utility model. Figure 1-2 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Example:

[0021] like Figures 1 to 2As shown, this utility model discloses an anti-pinch zipper, including two chain straps 1 and a zipper head 3 disposed between the two chain straps 1. At the same time, chain teeth 2 are fixedly provided on the ends of the chain straps 1 that are close to each other. This part is the prior art. A baffle 11 is fixedly provided on the ends of the chain straps 1 that are far from each other. The baffle 11 is made of flexible rubber material. In daily wear, the baffle 11 is used to cover the lining of the clothing to prevent the lining of the clothing from being caught between the zipper head 3 and the chain teeth 2 during the movement of the zipper head 3. At the same time, a limiting mechanism is provided on the chain straps 1 to prevent the baffle 11 from swinging towards the chain teeth 2.

[0022] The combination of the baffle 11 and the chain belt 1 is as follows: a first fabric layer 12 and a second fabric layer 13 are sequentially arranged on one side of the chain belt 1. The first fabric layer 12 and the second fabric layer 13 are sewn and fixed on the chain belt 1 at the end near the chain tooth 2, while the baffle 11 is sewn and fixed between the first fabric layer 12 and the second fabric layer 13.

[0023] Furthermore, the limiting mechanism includes a metal fastener 14 fixedly mounted on the chain belt 1. Multiple metal fasteners 14 are provided and arranged at intervals from top to bottom on the chain belt 1. In this structure, the metal fastener 14 is "U" shaped. The middle part of the metal fastener 14 penetrates the chain belt 1, and the two ends of the metal fastener 14 extend away from the chain teeth 2 and are respectively clamped on the outer side of the chain belt 1 and the second fabric layer 13. At the same time, a portion of the area of ​​the baffle 11 overlaps with the area of ​​the metal fastener 14.

[0024] With this structure, the metal fastener 14 is used to further fix the baffle 11 to the chain belt 1, and when the end of the chain belt 1 away from the chain tooth 2 is bent toward the chain tooth 2, the metal fastener 14 can always maintain a certain angle between the chain belt 1 and the zipper 3, and this setting can further ensure that the lining of the garment is kept at a certain distance from the chain tooth 2 and the zipper 3.

[0025] An auxiliary piece 15 is provided extending from the middle of the baffle 11. The end of the auxiliary piece 15 near the chain tooth 2 is used to abut against the end of the metal fastener 14. At the same time, a reinforcing rib 16 is provided between the included angle of the auxiliary piece 15 and the baffle 11. In this structure, the reinforcing rib 16 is integrally formed with the auxiliary piece 15 and the baffle 11. This arrangement can further prevent the baffle 11 from folding over in the direction of the chain tooth 2.

[0026] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.
