Abstract
The utility model relates to a half-moon type zipper, and consists of a zipper head, a sprocket and a chain belt; the sprocket is formed by a semi-cylinder shape left sprocket unit and a semi-cylinder shape right sprocket unit, a circular arc side wall of a left body unit (1) of the sprocket is provided with a groove (2) which divides the left body unit (1) into an outer side wall (5) and an inner side wall (3) which is provided with a notch (4), the thickness of a right body unit (6) of the sprocket is less than the wideness of the groove (2) on the circular arc side wall of the left body unit (1), a bump (7) is arranged at the inner side wall of the right body unit (6) and the shape and the size of the bump (7) is matched with that of the notch (4) on the lower side wall (3) of the left body unit (1); the half-moon type zipper has the advantages that the durability is good and does not happen tripping caused by wearing; the zipper has beauty appearance and flowing lines and is suitable for various fashion without automatic sliding, and the use is safe and convenient.
Description
Technical field
The utility model relates to a kind of slide fastener, particularly relates to a kind of half-moon-shaped slide fastener.
Background technology
The purposes of slide fastener is very extensive.At present, the slide fastener majority on the market still is the slide fastener of traditional miaow tooth form sprocket, and its shortcoming one is a poor durability, because slide fastener often will be opened, closure, causes wearing and tearing easily, and leans on the slide fastener of miaow tooth engagement, because the size of miaow tooth is less relatively, thread off in use because of wearing and tearing easilier; The 2nd, its form is more single, and profile is attractive in appearance inadequately, and also there is certain limitation in the fashionable dress that is used to become more diverse; Have, miaow tooth form slide fastener also in use slips off voluntarily through regular meeting, brings inconvenience again.
Summary of the invention
In order to overcome the weak point of existing slide fastener product, the utility model provides a kind of half-moon-shaped slide fastener, has good looking appearance, and durability is good, is difficult for the characteristics of threading off.
The technical solution of the utility model is achieved in that a kind of half-moon-shaped slide fastener, comprises slider of zipper fastener, sprocket and chain belt.Described sprocket by about two be semi-cylindrical sprocket unit and constitute, have a groove on the circular arc sidewall of the left body unit of sprocket, left body unit is divided into lateral wall and madial wall, have a breach on the madial wall; The thickness of the right body unit of sprocket is slightly less than the width of the groove on the circular arc sidewall of left body unit, and the madial wall of right body unit is provided with a projection, and the shape of this projection and size are complementary with breach on the described left body unit madial wall.
Breach on the left body unit madial wall of described sprocket is the prismatoid shape of arc surface for one side.
The straight wall that the left body unit of described sprocket is relative with the circular arc sidewall is fixed on the strap, and the circular arc sidewall of the right body unit of sprocket is fixed on the strap.
During use, the straight wall end that described right body unit is relative with the circular arc sidewall inserts in the groove on the circular arc sidewall of described left body unit, and the projection on this moment described right body unit madial wall just in time inserts in the breach on the described left body unit madial wall and coincide with it.
The beneficial effects of the utility model are: durability is good, can not produce the dropout phenomenon because of wearing and tearing; The good looking appearance of slide fastener, the lines flow smoothly, is applicable to the fashionable dress that pattern is various; Can not produce the phenomenon that slips off voluntarily, use very relieved, convenient.
Description of drawings
Accompanying drawing 2 is structure charts of the right body unit of sprocket of the half-moon-shaped slide fastener of this programme, and wherein: 6 is right body unit, and 7 is projection.
Accompanying drawing 3 is partial schematic diagrams of the half-moon-shaped slide fastener of this programme, and wherein: 1 is left body unit, and 6 is right body unit, the 8th, and strap.
The specific embodiment
A kind of half-moon-shaped slide fastener as accompanying drawing comprises slider of zipper fastener, sprocket and chain belt.Described sprocket by about two be semi-cylindrical sprocket unit and constitute, have a groove 2 on the circular arc sidewall of the left body unit 1 of sprocket left body unit 1 be divided into lateral wall 5 and madial wall 3, have a breach 4 on the madial wall 3; The thickness of the right body unit 6 of sprocket is slightly less than the width of the groove 2 on the circular arc sidewall of left body unit 1, and the madial wall of right body unit 6 is provided with a projection 7, and the shape of this projection 7 and size are complementary with breach 4 on described left body unit 1 madial wall 3.
Breach 4 on left body unit 1 madial wall 3 of described sprocket is the prismatoid shape of arc surface for one side.
The straight wall that the left body unit 1 of described sprocket is relative with the circular arc sidewall is fixed on the strap 8, and the circular arc sidewall of the right body unit 6 of sprocket is fixed on the strap 8.
During use, the straight wall end that described right body unit 6 is relative with the circular arc sidewall inserts in the groove 2 on the circular arc sidewall of described left body unit 1, and the projection 7 on this moment described right body unit 6 madial walls just in time inserts in the breach 4 on described left body unit 1 madial wall 3 and coincide with it.
Claims (2)
1. half-moon-shaped slide fastener, comprise slider of zipper fastener, sprocket and chain belt, it is characterized in that: described sprocket by about two be semi-cylindrical sprocket unit and constitute, have a groove (2) on the circular arc sidewall of the left body unit (1) of sprocket left body unit (1) is divided into lateral wall (5) and madial wall (3), have a breach (4) on the madial wall (3); The thickness of the right body unit (6) of sprocket is slightly less than the width of the groove (2) on the circular arc sidewall of left body unit (1), the madial wall of right body unit (6) is provided with a projection (7), and the breach (4) on the shape of this projection (7) and size and described left body unit (1) madial wall (3) is complementary.
