Abstract
The utility model discloses a zipper tooth, which comprises a tooth body, a tooth head and a through hole, wherein the through hole is used for a zipper cotton tape to pass through; the tooth head is arranged at one end of the tooth body and consists of two grooves which are communicated with each other; and the tooth body is provided with the through hole for the zipper cotton tape to pass through. The two grooves which are communicated are divided into a first groove and a second groove respectively, and the first groove is near one end of the through hole for the zipper cotton tape to pass through. The first groove is wider than the second groove. The through hole for the zipper cotton tape to pass through is fan-shaped. The zipper tooth disclosed by the utility model is high in single-tooth strength, cannot be easily cracked and can be smoothly pulled off, is good in pull-off strength, cannot prick hands, is simple in manufacturing and is suitable for being widely applied.
Description
Technical field
The utility model relates to a kind of zipper teeth grain, belongs to the tooth grain of the slide fastener that is applicable to clothes, case and bag locking.
Background technology
At present, widely used slide fastener has metal zip fastener, nylon zipper, glue tooth slide fastener on the market.Traditional nylon zipper, glue tooth slide fastener belong to plastic products, in use easily distortion, and because the insufficient strength of plastics is good, have a strong impact on service life and the quality of slide fastener.And traditional metal zip fastener is to use copper strips to be compressed on the strap through Sheet Metal Forming Technology, owing to a little less than single tooth interlock dynamics, make slide fastener intensity inhomogeneous, and double end drawing even can't use.And the slide fastener appearance is coarse, profile is not attractive in appearance, and pitch is inhomogeneous and cause that drawing has some setbacks sometimes during punching press.
The utility model content
The purpose of this utility model be to provide a kind of single tooth dynamics strong, be difficult for splitting, do not prick the hand, drawing zipper teeth grain smoothly.
The technical scheme that addresses the above problem is: a kind of zipper teeth grain, comprise tooth grain body, tooth head, place the through hole of zipper cloth belt, described tooth head is located at an end of described tooth grain body, is made of two grooves that are connected, and described tooth grain body is provided with the through hole that places zipper cloth belt.
Described two grooves that are connected are respectively the first groove and the second groove, and the first groove is near an end that places the through hole of zipper cloth belt.
Described the first recess width is greater than the second groove.
Described the first recess width equals the second groove.
The through hole that places zipper cloth belt is fan-shaped.
The utility model has the advantage of the design of two groove tooth heads that are connected so that slide fastener every pair of tooth grain interlock dynamics is strong, interlock is accurate, and is stable, so that slide fastener is difficult for splitting, do not prick the hand, and drawing is smooth and easy.Use metal material so that slide fastener is not yielding, it is lasting to use.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is the schematic diagram of zipper teeth grain of the present utility model;
Fig. 2 is the slide fastener schematic diagram of an embodiment of the utility model.
The specific embodiment
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not consist of the restriction to the utility model protection domain.
Shown in Fig. 1,2, a kind of zipper teeth grain provided by the utility model comprises tooth grain body 1, tooth head 2, places the through hole 3 of zipper cloth belt, and tooth head 2 is located at an end of tooth grain body 1, be made of two grooves that are connected, tooth grain body 1 is provided with the through hole 3 that places zipper cloth belt.Two grooves that are connected are respectively the first groove 4 and the second groove 5, the first grooves 4 near an end that places the through hole 3 of zipper cloth belt.The width of the first groove 4 is greater than the second groove 5.Place the through hole 3 of zipper cloth belt for fan-shaped.The tooth grain adopts metal material, especially often adopts copper to make.The thickness of tooth is 0.85mm, and width is 2.95mm.Sturdy and durable.The design of the tooth head of two grooves that are connected is so that slide fastener interlock dynamics is strong, and the zipper teeth grain is difficult for perk, can not cause pricking the hand, and also can not cause drawing to have some setbacks, and uses metal material so that slide fastener is not yielding, and it is lasting to use.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
