Abstract
The utility model discloses a back stop of a close end of a zipper. The back stop comprises an upper plate (1), a lower plate (2) and a basal part (3), wherein the upper plate (1) and the lower plate (2) are respectively arranged at the upper end and the lower end of the basal part (3); the upper plate (1), the lower plate (2) and the basal part (3) integrally form an I shape; a groove (4) is formed on the end surface formed by the upper plate (1), the lower plate (2) and the basal part (3); and the groove (4) is larger than zipper chain teeth matched with the back stop for use. When the back stop is stamped on a zipper cloth tape (6) of the zipper, even if the distance between the back stop and the zipper chain teeth is very short or even minus distance is reached, the chain teeth of the zipper is positioned in the groove (4), so that the chain teeth of the zipper cannot be damaged, and the aim of protecting the chain teeth of the zipper is achieved.
Description
Technical field
The utility model relates to back end above a kind of slide fastener, and is particularly a kind of can effectively prevent to end after installation the time, ends after damaging the close tail of slide fastener of zipper sprocket.
Background technology
Chinese patent ZL200710192784.2 discloses a kind of back sign indicating number that ends of slide fastener, and the back is ended sign indicating number and is made of upper plate, lower plate and baseplate part.Upper plate is formed by the flat board that can not be out of shape, and has flanging, and flanging is formed on each side by each side with right angle bending upper plate.Concave part with circular cross-section is arranged on the centre at the back side of lower plate, and arm is arranged on the both sides of concave part, so that arm leaves from upper plate gradually, and the middle part of upper plate and lower plate is connected by base portion.It can prevent effectively that the back from only the crack occurring in the sign indicating number, preventing distortion.
As only similar behind the slide fastener of above-mentioned patent disclosure, the cross section of ending behind the slide fastener that existing market is used is "working"-shaped mostly, relies on the punching press of external force, will only be stamped on the chain strap behind the slide fastener.Behind above-mentioned slide fastener, ending,, only also bring certain problem behind such slide fastener though the firm performance, the aesthetic measure that end behind the slide fastener have obtained certain improvement.
The sprocket of slide fastener is installed when for example ending after slide fastener is installed, and for the installation requirement that ends behind the slide fastener is: end between needs and the sprocket behind the slide fastener and leave certain distance.If above-mentioned distance is very big, not only influence the overall appearance degree of slide fastener, and excessive distance has then lost the effect that only can play originally behind the slide fastener; When if above-mentioned distance is too small, when on the chain strap that only is stamped into slide fastener behind the slide fastener, tend to be stamped into sprocket, cause the damage of sprocket, thereby cause scrapping of slide fastener.
The utility model content
Technical problem to be solved in the utility model is ended after providing a kind of close tail of slide fastener that can effectively avoid damaging sprocket in producing the slide fastener process.
In order to realize above-mentioned technical purpose, the technical solution of the utility model is: end behind the close tail of a kind of slide fastener, comprise upper plate, lower plate and base portion, upper plate, lower plate are separately positioned on the upper and lower side of base portion, upper plate, lower plate and base portion integral body are " worker " font, the end that forms at upper plate, lower plate and base portion is provided with groove, described groove greater than with the close tail of slide fastener after the zipper sprocket that only is used.Certainly, if the shape of groove is too small, then do not have the purpose of this utility model.
When on the chain strap that only is stamped into slide fastener behind the close tail of slide fastener; even end behind the close tail of slide fastener very little with the distance of zipper sprocket, even reach negative apart from the time, the sprocket of slide fastener is pressed in the groove the inside; therefore can not damage the sprocket of slide fastener, play the purpose of protection zipper sprocket.
For the ease of producing, the front/rear end place that forms at described upper plate, lower plate and base portion is provided with groove, when producing like this with regard to not can because of behind the close tail of slide fastener only direction put upside down and lose time, help the automation of slide fastener, large-scale production.
Described upper plate, lower plate are provided with flanging portion, and described flanging portion is formed on the side of upper plate, lower plate by each side of bending upper plate, lower plate.Only be arranged on securely on the chain strap of slide fastener after being provided with of flanging portion is beneficial to the close tail of slide fastener, when avoiding external force excessive, only come off behind the close tail of slide fastener from the chain strap.
End by simple groove is set behind the close tail of slide fastener of the present utility model, on the basis that does not increase cost, avoided the damage of zipper sprocket effectively, improved the quality of slide fastener.The damage of zipper sprocket often causes scrapping of whole piece slide fastener, and the utility model just can reduce slide fastener because of the scrappage that the sprocket damage brings like this, has saved production cost.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The structural representation of Fig. 1 for ending behind the close tail of the utility model slide fastener.
Fig. 2 be among Fig. 1 A-A to cutaway view.
The specific embodiment
As shown in Figure 1, end behind the close tail of a kind of slide fastener, comprise upper plate 1, lower plate 2 and base portion 3, upper plate 1, lower plate 2 are separately positioned on the upper and lower side of base portion 3, upper plate 1, lower plate 2 and base portion 3 integral body are " worker " font, the end that forms at upper plate 1, lower plate 2 and base portion 3 is provided with groove 4, described groove 4 greater than with the close tail of slide fastener after the zipper sprocket that only is used.
Above-mentioned upper plate 1, lower plate 2 are provided with flanging portion 5, and described flanging portion 5 is formed on the side of upper plate 1, lower plate 2 by each side of bending upper plate 1, lower plate 2.Only be arranged on securely on the chain strap 6 of slide fastener after being provided with of flanging portion 5 is beneficial to the close tail of slide fastener, when avoiding external force excessive, only come off behind the close tail of slide fastener from chain strap 6.
When on the chain strap 6 that only is stamped into slide fastener behind the close tail of slide fastener, though end behind the close tail of slide fastener very little with the distance of zipper sprocket, even reach negative apart from the time, the sprocket of slide fastener can not damage yet, and plays the purpose of protection zipper sprocket.
For the ease of producing, the front/rear end place that forms at described upper plate 1, lower plate 2 and base portion 3 is provided with groove 4, when producing like this with regard to not can because of behind the close tail of slide fastener only direction put upside down and lose time, help the automation of slide fastener, large-scale production.
Can clearly be seen that position and the structure of groove 4 on ending behind the close tail of slide fastener from Fig. 2.Groove 4 can be arranged to consistent with the shape of zipper sprocket, only need both can greater than zipper sprocket.
The groove 4 that the utility model is provided with is simple in structure, has avoided the damage of zipper sprocket on the basis that does not increase cost effectively, has improved the quality of slide fastener.The damage of zipper sprocket often causes scrapping of whole piece slide fastener, and the utility model just can reduce slide fastener because of the scrappage that the sprocket damage brings like this, has saved production cost.
The foregoing description limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in the protection domain of the present utility model.
