Detailed Description

The utility model is described in further detail below with reference to fig. 1-3.

The embodiment of the utility model discloses a double-opening zipper.

Referring to fig. 1, a double-open slide fastener includes two fastener tapes 1, between which two fastener tapes 1 are commonly provided slider 2, the number of sliders 2 is two, and slider 2 is used for connecting/separating the two fastener tapes 1; the two cards are rotatably arranged on the zipper head 2, and rough surfaces are arranged at the joint between the two pull tabs 21 and the zipper head 2, so that the situation that the pull tabs 21 are free to rotate on the zipper head 2 can be reduced. Both cards are provided with a clamping groove 22; the clamping groove 22 comprises a waist-shaped hole 23 and a plug-in hole 24, the inner diameter of the waist-shaped hole 23 is smaller than that of the plug-in hole 24, and the waist-shaped hole 23 is communicated with the plug-in hole 24.

The chain belt 1 is provided with a decorative belt, and one side of the decorative belt is sewn with a chain cloth of the chain belt 1. The two chain belts 1 are provided with auxiliary strips 3, and the extension direction of the auxiliary strips 3 is the same as that of the chain belts 1; the auxiliary strip 3 is positioned between the decorative belt and the chain cloth of the chain belt 1, and the auxiliary strip 3 is hidden below the decorative belt, so that the attractive appearance of the zipper can be improved.

Referring to fig. 2, the auxiliary strip 3 is provided with a plurality of clips 31, all clips 31 are disposed at intervals along the length direction of the auxiliary strip 3, and all clips 31 are disposed obliquely in a direction away from the chain belt 1 side. An elastic clamping block 32 is arranged on one side of the clamping block 31 away from the auxiliary block, and the inner diameter of one side of the elastic clamping block 32 away from the clamping block 31 is smaller than the inner diameter of one side of the elastic clamping block 32 close to the clamping block 31, namely the shape of the elastic clamping block 32 is a truncated cone; the inner diameter of the insertion hole 24 is smaller than the maximum outer diameter of the elastic clamping block 32.

Referring to fig. 3, in the process of fixing the pull tab 21 and the clamping block 31, the elastic clamping block 32 has elasticity and can be deformed, so that the elastic clamping block 32 is deformed when the plugging hole 24 is penetrated through the clamping block 31; since the inner diameter of the insertion hole 24 is smaller than the maximum inner diameter of the elastic clamping block 32, the clamping groove 22 can be reduced from being separated from the elastic clamping block 32. The shape of the elastic clamping block 32 is set to be round table, so that one end of the elastic clamping block 32 away from the clamping block 31 has a guiding function, and the clamping groove 22 is convenient to insert into the elastic clamping block 32. After the inserting hole 24 penetrates through the elastic clamping block 32, the clamping block 31 is normally positioned in the kidney-shaped hole 23, and the possibility that the pull tab 21 is separated from the clamping block 31 is further reduced because the width of the kidney-shaped hole 23 is smaller than the inner diameter of the inserting hole 24, namely the width of the kidney-shaped hole 23 is smaller than the maximum outer diameter of the elastic clamping block 32.

In this embodiment, one of the clamping grooves 22 of the pull tab 21 is provided, and in other embodiments, the number of the clamping grooves 22 of the pull tab 21 is two, and the two clamping grooves 22 are matched with the two clamping blocks 31 on the auxiliary strip 3 for insertion, so that the possibility that the clamping grooves 22 of the pull tab 21 are separated from the clamping blocks 31 is further reduced.

The sprocket department of chain belt 1 is provided with magnet (not shown in the figure), through setting up magnet, can increase the steadiness after two chain belts 1 connect, reduces the condition that the sprocket junction between two points appears not hard up.

The implementation principle of the double-opening zipper provided by the embodiment of the utility model is as follows:

when the two chain belts 1 are connected by the zipper puller, the zipper puller 21 rotates along the hinge joint of the zipper puller 2, so that the zipper puller 21 moves towards one side of the clamping block 31, the clamping block 31 is clamped into the clamping groove 22, the fixation between the zipper puller 2 and the chain belts 1 can be completed, and the situation that the zipper puller 2 moves freely is reduced; by arranging the clamping blocks 31 obliquely, the possibility that the clamping grooves 22 of the zipper pull 21 are separated from the clamping blocks 31 at will is further reduced, and the stability between the zipper head 2 and the zipper belt 1 is improved.

The above is a preferred embodiment of the present utility model, and is not intended to limit the scope of the present utility model in this way, therefore: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
