Problems solved by technology

The zipper in the prior art is composed of several zipper blocks, and only a single zipper tooth is provided on the zipper block. When the slider pulls the zipper block to merge or open, the two adapted zipper blocks are easy to "break" or "break". The two zipper blocks are separated, or the zipper block is astringent, and the sliding part will get stuck, resulting in unsmooth opening and closing of the zipper, and inflexible pulling

Embodiment 1

[0028] Such as Figure 1-2 As shown, a zipper includes two zipper tapes 1 and two zipper sets 2 . The edges of the zipper tape 1 are provided with installation ribs 11 , and each zipper group 2 is clipped on one installation rib 11 respectively, and the two zipper groups 2 are fastened together. The installation rib 11 is in a cylindrical shape, which is for the convenience of the installation of the zipper set 2 and also for safety.

[0029] Such as image 3 As shown, each zipper set 2 includes a plurality of zipper blocks 3 arranged in sequence, the outer side of the zipper block 3 is provided with a mounting groove 31 for inserting on the installation rib 11, and one end of the inner side of the zipper block 3 is provided with a snap tooth 32, the other end is provided with a guide tooth 33; a buckle groove 34 is formed between the buckle tooth 32 and the guide tooth 33 on each zipper block 3 in the same zipper group 2, and is used for fitting on another zipper group 2 T...

Embodiment 2

[0032] Such as Figure 4 , 6 As shown, the fastening teeth 32 and guide teeth 33 on the same zipper block 3 are arranged on the upper layer on the side of the zipper block 3 away from the mounting groove 31, and the lower layer on this side is provided with reinforcing teeth 36, and the reinforcing teeth 36 and the fastening teeth 32. The guide teeth 33 are arranged alternately and misplaced. A reinforcing groove 37 is provided on a side of the reinforcing tooth 36 close to the guide tooth 33 , for snap-fitting the matching reinforcing tooth 36 on another zipper set 2 . The reinforcing tooth 36 is a cube shape, and the reinforcing groove 37 of the reinforcing tooth 36 is a smooth concave surface 371. The setting of the smooth concave surface 371 makes the zipper blocks 3 on the two zipper tapes 1 open and close when the slider is closed or pulled apart. more smoothly.

[0033] Other structures and connection methods are the same as in Embodiment 1.

[0034] The upper layer...

Embodiment 3

[0036] Such as Figure 5 As shown, the side of the fastening teeth 32 on the same zipper block 3 facing the guide teeth 33 is provided with a smooth arc surface 321 which is conducive to fastening; Smooth curved surface 331 for snap fit. The arrangement of the smooth curved surface 321 and the smooth curved surface 331 makes the opening and closing of the zipper blocks 3 on the two zipper tapes 1 more smooth when the sliders are closed or pulled apart.

[0037] The inner side of the curved surface 331 of the guide tooth 33 is provided with an arc-shaped convex portion 332 , and the outer side of the curved surface 331 is provided with an arc-shaped concave portion 333 , and the arc-shaped convex portion 332 and the arc-shaped concave portion 333 are connected smoothly. The setting of the arc-shaped convex portion 332 and the arc-shaped concave portion 333 of the guide tooth 33 is to make the snap connection of the two guide teeth 33 tighter, and the setting of the smooth tran...

Abstract

The invention discloses a zipper which comprises two zipper bands and two zipper sets. Each zipper set comprises a plurality of zipper blocks arranged in sequence, mounting grooves for being inserted into mounting ribs are formed in the outer sides of the zipper blocks, a buckle tooth is arranged at one end of the inner side of each zipper block, and a guide tooth is arranged at the other end of the inner side of each zipper block. Guide grooves are formed between the buckle tooth on each zipper block in the same zipper set and the guide teeth on the adjacent zipper blocks and used for allowing the matched guide teeth of the zipper blocks in the other zipper set to be embedded therein. The buckle teeth are embedded in the corresponding buckle grooves, the guide teeth are embedded in the corresponding guide grooves, the transverse tensile strength is greatly improved, and the phenomenon of breakage or tooth disengagement of the zipper is avoided.

Description

technical field [0001] The invention relates to a zipper and belongs to the technical field of industrial products. Background technique [0002] Zipper, as a connecting piece for merging or separating items, is now widely used in clothing, packaging, tents and other items to connect the edges of the openings of these items. There is a sliding piece that can pull two rows of zipper blocks into the interlocking position to close the opening or Open. The zipper in the prior art is composed of several zipper blocks, and only a single zipper tooth is provided on the zipper block. When the slider pulls the zipper block to merge or open, the two adapted zipper blocks are easy to "break" or "break". If the two zipper blocks are separated, or if the zipper block is astringent, the sliding part will get stuck, resulting in the zipper not opening and closing smoothly and pulling inflexibly. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, ...
