Detailed Description

The utility model is described in further detail below with reference to fig. 1-4.

Referring to fig. 1 and 2, the slide fastener includes two fastener tapes 1, two sets of fastener elements 2 and a slider 3, the fastener elements 2 are connected to the fastener tapes 1, the slider 3 is disposed between the two fastener tapes 1, and left and right sides of the slider 3 are slidably connected to the two fastener tapes 1, respectively. The slider 3 includes a main body 31 and a pull tab 32, the main body 31 includes an upper sheet 311, a bottom sheet 312, and a connecting post, the pull tab 32 is connected to the upper sheet 311, and the bottom sheet 312 is connected to the upper sheet 311 through the connecting post. The bottom plate 312 has abutment portions 3121 on both left and right sides, and the abutment portions 3121 are for abutment of the fastener elements 2. When the zipper is applied to clothing sewn with lining cloth, gaps between adjacent zipper teeth 2 can be periodically exposed in the process that a user slides the zipper head 3 relative to the zipper belt 1, and under the further guiding action of the zipper teeth 2, the lining cloth is easily rolled between the zipper head 3 and the zipper teeth 2, so that the zipper is blocked.

The embodiment of the utility model discloses an anti-jamming zipper, which is used for reducing the risk of jamming of the zipper caused by rolling inner cloth of a garment between a zipper head 3 and zipper teeth 2.

Example 1

Referring to fig. 2, the first slider 4 and the second slider 5 are fixedly bonded to the back surface of the fastener tape 1, and the first slider 4 and the second slider 5 are disposed so as to extend in the longitudinal direction of the fastener tape 1, and the axes of the first slider 4 and the second slider are parallel to each other. The first slider 4 is located between the fastener element 2 and the first abutting portion 3121, and two surfaces of the abutting portion 3121 facing away from each other are respectively used for abutting the first slider 4 and the second slider 5.

When the zipper head 3 slides relative to the zipper teeth 2, the first sliding strip 4 is used for blocking the zipper teeth 2, namely, gaps between adjacent zipper teeth 2 periodically exposed when the zipper head 3 slides are blocked by the first sliding strip 4, so that the risk of zipper locking caused by rolling cloth in clothing between the zipper head 3 and the zipper teeth 2 is reduced.

The second slider 5 is designed in such a manner that the risk of the lining getting stuck between the abutment 3121 and the fastener tape 1 is reduced by the clearance between the blocking abutment 3121 of the second slider 5 and the fastener tape 1.

Further, referring to fig. 2, in order to enhance the sliding stability of the slider 3 with respect to the first slider 4, the surface of the bottom sheet 312 facing the fastener tape 1 is provided with a slide groove 3123 for sliding connection of the first slider 4.

Further, referring to fig. 2, the abutting portion 3121 has a guide surface 3122, and a dihedral angle is formed between the guide surface 3122 and the surface of the fastener tape 1 to be an obtuse angle, so that when the lining moves between the first slider 4 and the second slider 5, the risk that the lining continues to move between the abutting portion 3121 and the fastener tape 1 is reduced by the guide action and the blocking action of the guide surface 3122, and the risk that the lining is caught between the abutting portion 3121 and the fastener tape 1 is further reduced.

Further, the guide surface 3122 and the abutment portion 3121 are in contact with the surface of the fastener tape 1 through an arc transition, so that smoothness of sliding of the abutment portion 3121 with respect to the fastener tape 1 is improved.
