Detailed Description

The present utility model will be described in detail below with reference to the accompanying drawings and examples.

An anti-theft zipper is shown in fig. 1 and 3, and comprises a zipper head 1 and a pair of zipper teeth 2 which can be meshed with each other, wherein a cavity 4 is formed in the zipper head 1, the zipper teeth 2 slide in the cavity 4, an anti-skid plate 3 is connected in the cavity 4 in a sliding manner, the anti-skid plate 3 can be in abutting joint with the top surfaces of the zipper teeth 2, the anti-skid plate 3 is in abutting joint with the top surfaces of the zipper teeth 2 through sliding the anti-skid plate 3, at the moment, the contact area between the anti-skid plate 3 and the zipper teeth 2 is increased, so that the friction force between the anti-skid plate 3 and the zipper teeth 2 is increased, the position of the zipper head 1 is fixed, the zipper head 1 is effectively prevented from sliding when a purse or a handbag is closed, the safety performance of the zipper is improved, the anti-theft effect of the zipper head 1 is achieved, and the practicability of the zipper is further improved; the antiskid plate 3 is fixed with the mounting that is used for fixed antiskid plate 3 between cavity 4 inner wall, so accessible mounting is fixed antiskid plate 3 after antiskid plate 3 slides to avoid antiskid plate 3 to take place to slide at will, influence the use of zip fastener.

As shown in fig. 2, fig. 4 and fig. 5, the two side walls of the antiskid plate 3 are fixedly connected with the sliding blocks 8, the two side walls of the cavity 4 close to the sliding blocks 8 are provided with the strip-shaped sliding grooves 7 which are convenient for the sliding blocks 8 to slide, and the strip-shaped sliding grooves 7 and the sliding blocks 8 are obliquely arranged, so that when the antiskid plate 3 is pushed into the cavity 4, the sliding blocks 8 slide along the strip-shaped sliding grooves 7, and in the sliding process, the gap between the bottom surface of the antiskid plate 3 and the top surface of the zipper teeth 2 is gradually reduced until the bottom surface of the antiskid plate 3 and the top surface of the zipper teeth 2 form butt connection, and at the moment, the zipper head 1 can be fixed, so that the zipper head 1 is prevented from being easily pulled open when a bag is carried out.

As shown in fig. 4, 5 and 6, the anti-slip plate 3 is fixedly connected with an anti-slip pad 9 on a side wall close to the fastener teeth 2, the anti-slip pad 9 has elasticity, the anti-slip pad 9 is separated from the fastener teeth 2 when in a natural state, and when the anti-slip plate 3 is tightly attached to the fastener teeth 2, the anti-slip pad 9 deforms due to acting force and generates reaction force to the fastener teeth 2 when deforming, so that the fixation between the anti-slip plate 3 and the fastener teeth 2 is firmer, and meanwhile, the friction force between the anti-slip plate 3 and the fastener teeth 2 can be further increased by the anti-slip pad 9, so that the fixation effect on the slider 1 is improved.

As shown in fig. 4, 5 and 6, the thickness of one end of the antiskid plate 3 close to the cavity 4 is smaller than that of one end far away from the cavity 4, and along with the gradual sliding of the antiskid plate 3 into the cavity 4, the gap between the top surface of the antiskid plate 3 and the inner top surface of the cavity 4 gradually decreases until the antiskid plate is abutted with the inner wall of the cavity 4, at this time, the bottom surface of the antiskid plate 3 is precisely attached to the top surface of the zipper teeth 2, so that the zipper head 1 is fixed, the zipper head 1 is prevented from sliding easily due to acting force, and meanwhile, the design enables the antiskid plate 3 to slide into the cavity 4 easily, so that the zipper head 1 is better fixed, and the convenience and practicality of operation are improved.

As shown in fig. 4, 5 and 6, the fixing member includes a plurality of bumps 5 fixedly connected to the top surface of the anti-slip plate 3, the inner wall of the cavity 4 is provided with a groove 6, the bumps 5 can form an abutting joint with the groove 6, when the anti-slip plate 3 slides into the cavity 4, the bumps 5 and the groove 6 form an abutting joint, thereby fixing the anti-slip plate 3, preventing the anti-slip plate 3 from sliding to affect the use of the anti-slip plate 3 when in use, meanwhile, the bumps 5 have elasticity and the top surface is provided with an arc surface, and can be clamped into the groove 6 more easily when the anti-slip plate 3 slides into the cavity 4, so that the anti-slip plate 3 is fixed, and when the anti-slip plate 3 slides into the cavity 4, the top end of the anti-slip plate 3 is positioned outside the cavity 4, so that the anti-slip plate 3 can be pulled out easily when the fixing of the slider 1 is released.

Working principle:

after the slide fastener slider 1 slides, the slide fastener 3 is pushed into the cavity 4, at this time, along with the sliding of the slide fastener 3, the slide block 8 is located in the strip-shaped slide groove 7 to correspondingly slide, and because the strip-shaped slide groove 7 and the slide block 8 are obliquely arranged, the gap between the bottom surface of the slide fastener 3 and the top surface of the zipper teeth 2 is gradually reduced while sliding, and because the thickness of one end of the slide fastener 3 close to the cavity 4 is smaller than that of one end far away from the slide fastener 3, the gap between the top surface of the slide fastener 3 and the inner top surface of the cavity 4 is gradually reduced while the slide fastener 3 slides until the salient point 5 on the slide fastener 3 is clamped into the groove 6, at this time, the top surface of the slide fastener 3 is abutted with the inner top surface of the cavity 4, and the bottom surface of the slide fastener 3 is abutted with the top surface of the zipper teeth 2, at this time, the slide fastener 1 is fixed at this time, so that the slide fastener 1 has the effect of not easily sliding, and the safety performance and the anti-theft performance of the slide fastener 1 are improved.

The above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that modifications and adaptations to the present utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
