Technical Field

The invention belongs to the technical field of zippers, and particularly relates to high and low zipper teeth and a zipper.

Background

The zipper is a connecting piece which enables articles to be combined or separated by means of continuously arranged zipper teeth, and is widely applied to clothes, bags and the like. The zipper is composed of a puller, a lock hook, a cap, a pulling piece and zipper teeth, wherein the puller clamps the zipper teeth on two sides, and the zipper teeth on two sides can be meshed or separated with each other by means of sliding of the pulling piece.

With the pursuit of individuality of people, the zipper teeth in the prior art are divided into two parts after being pulled, so that the zipper teeth are of a split structure, and the surfaces of the zipper teeth are not individual and not rich in aesthetic feeling.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: aiming at the defects, the invention provides the high-low zipper teeth and the zipper, which adopt a high-low tooth structure, so that the front tooth shape is of an integral structure, the front tooth shape is attractive, the appearance and the surface can be set individually, and the individual requirements are met.

The technical scheme adopted by the invention for solving the technical problems is as follows: the high and low zipper teeth comprise high zipper teeth and low zipper teeth, and the height of the high zipper teeth is greater than that of the low zipper teeth; the high zipper tooth comprises a high tooth base part, a high tooth meshing part and a high tooth upper part, wherein the length of the high tooth upper part is greater than the sum of the lengths of the high tooth base part and the high tooth meshing part; the low tooth comprises a low tooth base part and a low tooth meshing part; the high tooth meshing teeth of the high zipper teeth are matched with the low tooth meshing teeth of the low zipper teeth, and the high tooth base parts and the low tooth base parts are the same in height. Through the high zipper teeth and the low zipper teeth, the zipper is closed or separated through the high tooth meshing teeth and the low tooth meshing teeth during closing, the upper parts of the high teeth can cover the surface of the low teeth after closing, and a zipper dividing structure is hidden, so that the front tooth form is an integral structure; the whole tooth shape is beautiful, the appearance and the surface of the front tooth shape can be conveniently set individually, and the individual requirements can be met.

Furthermore, a high tooth meshing part of the high zipper tooth is provided with a limiting bulge, and an open slot is formed among the limiting bulge, the upper part of the high tooth and the base part of the high tooth; the low tooth base part of the low zipper tooth is provided with a limiting table, the limiting table is arranged between the low tooth base part and the low tooth meshing part, and the limiting table is mutually restricted with the open groove when being meshed. The limiting bulges and the open grooves of the high zipper teeth are matched with the limiting platforms of the low zipper teeth, so that the low teeth can be prevented from being staggered up and down in the zipper closing process, the smoothness and the accuracy of zipper closing of the zipper teeth are ensured, and the service life of the zipper is prevented from being influenced.

Furthermore, the low tooth meshing surface of the low tooth which is in zipper contact with the high tooth is arc-shaped. The arc-shaped low-tooth engaging surface can enable the zipper teeth to be more smoothly closed after being closed, and can improve the flexibility of the combined zipper.

Further, the length of the upper portion of the high tooth is equal to the sum of the lengths of the high tooth base portion, the high tooth engaging portion, the low tooth engaging portion and the low tooth base portion. The length of the upper part of the high tooth is set, the upper part of the high tooth can completely cover the low tooth to hide the low tooth, and the low tooth is not too wide and cannot lose coordination and attractiveness.

Further, the upper surface of the high tooth is a curved arc or a plane; the upper part of the high tooth is rectangular or curved. The shape and the surface of the upper part of the high tooth can be rectangular or various irregular curved appearances, the surface can be made into a plane or irregular curved surface effect, and various technical printing words, trademarks and other magic effects can be processed on the surface of the tooth surface.

Further, the high zipper teeth are integrally formed; the low zipper teeth are integrally formed. The high zipper teeth and the low zipper teeth are integrally formed, the zipper production process is simple, and the processing is convenient.

The utility model provides a high low chain tooth zip fastener, the chain tooth is above-mentioned arbitrary high low chain tooth, still includes the pull head, including upper plate, hypoplastron, back shaft, lock hook, cap and pulling-on piece, be equipped with the abdication passageway on downward inclined plane on the back shaft, the abdication passageway corresponds with high tooth upper portion. The abdication channel is arranged, so that the high and low zipper teeth can be smoothly drawn, and the friction between the puller and the high zipper teeth is reduced.

Furthermore, the two side ends of the upper plate are provided with downward low zipper teeth for limiting, and the low zipper teeth can be effectively prevented from shaking up and down during zipper closing through the arrangement of the low zipper teeth for limiting, so that the zipper closing smoothness is improved.

The invention has the beneficial effects that:

1. through the high zipper teeth and the low zipper teeth, the zipper is closed or separated through the high tooth meshing teeth and the low tooth meshing teeth during closing, the upper parts of the high teeth can cover the surface of the low teeth after closing, and a zipper dividing structure is hidden, so that the front tooth form is an integral structure; the overall tooth shape is attractive, the appearance and the surface of the front tooth shape can be conveniently set individually, and the individual requirements are met; the limiting bulges and the open slots of the high zipper teeth are matched with the limiting platforms of the low zipper teeth, so that the low teeth can be prevented from being staggered up and down in the zipper closing process, the smoothness and the accuracy of zipper closing of the zipper teeth are ensured, and the service life of the zipper is prevented from being influenced; the length of the upper part of the high tooth is set, the upper part of the high tooth can completely cover the low tooth to hide the low tooth, and the low tooth is not too wide and loses coordination and beauty; the upper part of the high tooth can be in a rectangular shape or a plurality of irregular curved appearances, the surface can be in a plane or irregular curved surface effect, and various technical printing, trademarks and other magic effects can be processed on the surface of the tooth surface.

2. The arc-shaped low-tooth engaging surface can enable the zipper teeth to be more smoothly closed after being closed, and can improve the flexibility of the combined zipper.

3. The high and low zipper teeth zipper can be smoothly closed by arranging the abdication channel on the supporting shaft, and the friction between the puller and the high zipper teeth is reduced; through setting up the low chain tooth spacing, can effectively prevent to shake about the time low chain tooth of drawing, improve the smooth and easy degree that the zip fastener was drawn to close.
