Further, the outer surface of the inner tooth is bent from the head to the tail.

Furthermore, two sides of the inner teeth are provided with inner engaging grooves which are symmetrical with each other.

Specifically, the inner teeth and the outer teeth are made of plastic steel.

A chain belt comprises a cloth belt and a plurality of chain teeth arranged on the cloth belt.

A slide fastener comprises stringers and a slider, the stringers being constructed as described above.

An article having a zipper, the article having an opening and being provided with a zipper configured as described above for closing the opening.

From the above description of the present invention, the present invention has the following advantages:

one of the two, the utility model discloses well outer tooth forms wrong dentate structure with interior tooth dislocation set each other to there is the clearance after can avoiding the chain tooth meshing, improved the dustproof and the seal performance of chain tooth, and the utility model discloses well outer tooth is different with the structure of interior tooth, can make the positive and negative of drawing the back chain belt of closing demonstrate different visual effects, has overcome the single shortcoming of current chain tooth form from this, has improved the whole feel and the pleasing to the eye degree of chain tooth effectively.

Two of it, the utility model discloses the both sides of well outer tooth are the concave-convex structure of asymmetric design, make it closely detain mutually after drawing to present V style of calligraphy and distribute, be rich in three-dimensional gentle aesthetic feeling, interior tooth then adopts the symmetrical structure design, makes it have more feel and stereovision effect after drawing to close, has broken through the engraving plate image of traditional chain tooth.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in figures 1 and 2, the novel zipper tooth mainly comprises an outer tooth 2 and an inner tooth 3. The outer teeth 2 and the inner teeth 3 are arranged in a staggered mode to form a staggered tooth-shaped structure, so that gaps can be avoided after the zipper teeth are meshed, and the sealing performance of the zipper teeth is effectively improved.

As shown in fig. 1 and 2, the outer teeth 2 are asymmetrically designed, and the lower side of the surface of the outer teeth 2 is provided with a convex arc 21 in a columnar structure, and the upper side of the surface of the outer teeth is provided with an arc groove 22. Two outer engaging grooves 24 which are mutually asymmetric are respectively arranged on the upper side wall and the lower side wall of the outer tooth 2 (namely, two sides of the tooth head 23), and the concavity of the outer engaging groove 24 positioned on one side of the arc-shaped groove 22 is larger than that of the outer engaging groove 24 positioned on one side of the convex arc 21. When the zipper is pulled, the outer teeth 2 positioned on the left side and the right side of the chain belt 1 are mutually engaged, so that the two outer engaging grooves 24 with different concavity are mutually matched and tightly buckled, and the convex arc 21 and the arc-shaped groove 22 on the surface of the outer teeth 2 are combined to jointly present a V-shaped stereoscopic vision effect, so that the integral attractiveness of the zipper teeth is remarkably improved while the engagement strength of the zipper teeth is improved, and the zipper teeth are rich in three-dimensional soft aesthetic feeling and interesting feeling. It should be noted that the present invention adopts the terms of the upper, lower, left, right, etc. for the purpose of clearly explaining the specific structures of the external teeth 2 and the internal teeth 3 with reference to the drawings, and is not limited to the specific structural orientations.

As shown in fig. 3 and 4, the inner teeth 3 have regular symmetrical structures on both sides, and the inner tooth grooves 32 on both sides of the tooth head 31 are designed to be symmetrical with each other, so that the inner teeth 3 have an aesthetic wine bottle-shaped structure as a whole. The outer surface of the inner tooth 3 is in a curved surface design from the tooth head 31 to the tooth tail 33, so that the zipper has texture and stereoscopic vision effect after being pulled and combined, and the engraving image of the traditional zipper tooth is broken through.

As shown in fig. 4, 5 and 6, a chain belt comprises tapes 5 and a novel fastener element 10 having the structure as described above, wherein the fastener element 10 comprises an outer element 2 and an inner element 3, and a tape hole 4 for mounting the tape 5 is provided between the outer element 2 and the inner element 3. The inner sides of the outer teeth 2 and the inner teeth 3 are closely matched with the edges of the cloth belts 5 through the cloth belt holes 4, so that the sealing performance and the dustproof performance of the chain belt are improved.

As shown in fig. 1, as a preferred scheme: the outer teeth 2 and the inner teeth 3 are made of plastic steel materials integrally through injection molding or die casting, so that the structural strength of the zipper teeth can be effectively improved, and the service life of the zipper teeth is prolonged.

As shown in fig. 5 and 6, a slide fastener includes stringers and a slider, the stringers being constructed as described above.

As shown in fig. 5 and 6, an article having a zipper, the article having an opening and being provided with the zipper having the structure for closing the opening as described above. Specifically, the articles may be clothes or bags, bed articles such as quilt cover pillowslip, daily necessities such as storage bags, and interior articles such as automobile seat covers.

The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
