Abstract
The invention relates to a metal zipper tooth which comprises a head part and a pair of leg parts extending backward from the rear end of the head part to form a Y-shaped section, wherein the rear end of the head part is a plane; the outer surface of the pair of leg parts comprises a first plane connected with the side wall of the head part and a second plane connected with the first plane and turning inward; the inner surfaces of the pair of leg parts comprise a third plane connected with the rear end of the head part and a fourth plane connected with the third plane and turning inward; and the width of each leg part is gradually reduced and then gradually increased from front to back. According to the invention, the width of a pair of leg parts is gradually reduced and then gradually increased from front to back, and the width of the rear end of each leg part is the maximum, thus the occlusion strength of the zipper tooth can be increased, the drop off of the zipper tooth is prevented, and the zipper quality is improved; and due to the non-uniform design of the width of the leg parts, the material of the zipper tooth can be saved, and the cost is lowered.
Description
Technical field
The present invention relates to slide fastener, specifically a kind of metallic bond tooth that obtains by the cutting metal bar.
Background technology
Traditional slide fastener generally adopts the metallic bond tooth, and the metallic bond tooth is engaged in and forms half slide fastener on the zipper strip, and a pair of half slide fastener is combined the formation slide fastener.The metallic bond tooth comprises head and rear end extended a pair of shank backward from the head, consists of y-shaped cross-section.Usually, the width of this a pair of shank is uniformly, and namely everywhere width is identical.The chain tooth of this structure, its intensity that is engaged on the zipper strip is not too high, easily comes off from zipper strip, causes the damage of slide fastener, and and then affects the use of slide fastener.
Summary of the invention
The present invention is directed to the problems referred to above, provide a kind of keying strength high metallic bond tooth, use the slide fastener of this chain tooth not fragile, reliable in quality.
According to technical scheme of the present invention: a kind of metallic bond tooth, comprise head and the extended a pair of shank backward from the rear end of described head, consist of y-shaped cross-section, the rear end of described head is the plane, the outer surface of described a pair of shank comprises the second plane of the first plane that links to each other with described head side wall and the inside turnover that links to each other with described the first plane, the inner surface of described a pair of shank comprises Siping City's face of the 3rd plane that links to each other with described head rear end and the inside turnover that links to each other with described the 3rd plane, and the width of each described shank reduces to increase gradually more first from front to back gradually.
The connecting place of described the first plane and described head side wall is provided with bend.
The connecting place of described the 3rd plane and described head rear end and the connecting place on described Siping City face and described the 3rd plane are provided with bend.
Described bend is cancave cambered surface.
The front end of described head is aduncate cancave cambered surface.
Technique effect of the present invention is: the width of a pair of shank among the present invention reduces to increase gradually more first respectively from front to back gradually, and the rear end width of shank is maximum, can increase the keying strength of chain tooth, prevents the chain odontoptosis, improves the quality of slide fastener; The width of shank adopts inhomogeneous design, can save the material of chain tooth, reduces cost; The cancave cambered surface of head front end can increase the light slippery of pull head pulling when the slide fastener folding.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
Among Fig. 1, comprise head 10, front end 11, rear end 12, shank 13, bend 14, the first plane 15, the second plane 16, the 3rd plane 17, Siping City's face 18 etc.
As shown in Figure 1, the present invention is a kind of metallic bond tooth, comprises head 10 and 10 rear end 12 extended a pair of shank 13 backward from the head, consists of y-shaped cross-section.
The rear end 12 of head 10 is the plane, and the front end 11 of head 10 is aduncate cancave cambered surface.The cancave cambered surface of head 10 front ends 11 can increase the light slippery of pull head pulling when the slide fastener folding.
The outer surface of a pair of shank 13 comprises the second plane 16 of the first plane 15 that links to each other with head 10 sidewalls and the inside turnover that links to each other with the first plane 15, the inner surface of a pair of shank 13 comprises Siping City's face 18 of the 3rd plane 17 that links to each other with head 10 rear ends 12 and the inside turnover that links to each other with the 3rd plane 17, the width of each shank 13 reduces to increase gradually more first from front to back gradually, and the rear end width of shank 13 is maximum.
The first plane 15 of shank 13 outer surfaces is provided with bend 14 with the connecting place of head 10 sidewalls; The 3rd plane 17 and the connecting place of head 10 rear ends 12 and the connecting place on Siping City's face 18 and the 3rd plane 17 of shank 13 inner surfaces also are provided with bend 14.Bend 14 is cancave cambered surface, rounding off.
The width of a pair of shank 13 among the present invention reduces to increase gradually more first respectively from front to back gradually, and the rear end of shank 13 is the part of interlock zipper strip, and its width is maximum, can increase the keying strength of chain tooth, prevents the chain odontoptosis, improves the quality of slide fastener; The width of shank 13 adopts inhomogeneous design, can save the material of chain tooth, reduces cost.
