Abstract
The utility model provides a lower stopper structure of a zipper. The lower stopper structure comprises a plug pin base and a plug pin, wherein one side of the plug pin base is provided with a plug pin hole, a locking block is arranged on the side wall of the plug pin hole in a protruding mode and corresponds to the locking face on the plug pin, the other side of the plug pin base is provided with an edge slot, inclined slot walls are symmetrically arranged on the edge slot, and an arc base is further arranged at the bottom of the plug pin base. According to the lower stopper structure of the zipper, by means of improving the lower stopper structure, a lower stopper can be smoothly opened or closed and not prone to being stuck, the meshing strength of the plug pin base of the lower stopper and a cloth strip of the zipper is enough, and therefore the cloth strip and the plug pin base are connected more firmly.
Description
Technical field
The utility model relates to a kind of lower only structure for slide fastener, is specially a kind of lower only structure of zipper head, belongs to slide fastener technical field.
Background technology
The lower of slide fastener is only generally comprised of socket and latch, realizes the folding of zipper strip by this socket and latch.Application number is that 201220347720.1 Chinese utility model patent discloses a kind of structure that can lower stopper of zip.The lower only switching of structure of this kind of structure has some setbacks, easily stuck, and the strap keying strength of the lower plug housing stopping and slide fastener is inadequate, and strap easily skids off from plug housing.
Utility model content
The defect existing for prior art, the utility model provides a kind of lower stopper of zip structure, and the latch design that solves prior art is complicated, and lower switching only has some setbacks, lower only easily stuck, the shortcoming that strap easily skids off from plug housing.
A kind of lower stopper of zip structure of structure that the utility model is adopted, comprises plug housing and latch.
One side of this plug housing is provided with pin hole, on the sidewall of this pin hole, convexes with latch; This latch is corresponding to the locking face on latch.
The opposite side of this plug housing is provided with limit groove, on this limit groove, is arranged with chute wall.
The bottom of this plug housing is also provided with circular arc base.
Further, this latch number is two and is symmetrical arranged.
Further, this latch is shaped as triangle.
Further, be also provided with fluting on this pin hole, the bottom surface of this fluting is higher than the bottom surface of described pin hole.
Further, the bottom surface of this fluting is higher than the center of arc position of described circular arc base.
Further, the locking face number on this latch is two.
Further, the angle of this chute wall is 5-8 degree.
Further, this plug housing and latch are formed in one.
Compared with prior art, lower stopper of zip structure provided by the utility model, by improving down structure only, the latch that is, smooth and easy with only opening and closing at present, be difficult for stuckly, the strap keying strength of lower plug housing only and slide fastener is enough, and strap and plug housing are connected firmly.

The specific embodiment
A lot of details have been set forth in the following description so that fully understand the utility model.But the utility model can be implemented to be much different from alternate manner described here, those skilled in the art can do similar popularization without prejudice to the utility model intension in the situation that, so the utility model is not subject to the restriction of following public specific embodiment.
Embodiment 1
Refer to Fig. 1-Fig. 6, a kind of lower stopper of zip structure, comprises plug housing 1 and latch 2, and a side of this plug housing 1 is provided with pin hole 9, convexes with latch 3 on the sidewall of this pin hole; This latch 3 is corresponding to the locking face 4 on latch 2.The setting of latch 3, both the locking component in the time of slotting as latch 2 times, it contacts with the locking face 4 on latch simultaneously, bossing between the lower end locking face of latch 2 inserts in the middle of two latch simultaneously, can be so that the bonding strength of latch and pin hole be higher, but the structure of comparing existing latch and plug housing in background technology, makes the latch joint face of cambered surface into inclined-plane, be difficult for occurring stuck phenomenon.
Refer to Fig. 1-Fig. 6, the opposite side of this plug housing 1 is provided with limit groove 5, on this limit groove 5, is arranged with chute wall 6.The setting of chute wall 6, by writing edge strip and make into the skew wall of whole limit groove, makes the bonding strength of whole plug housing and zipper cloth belt higher, plug housing 2 difficult drop-offs
Refer to Fig. 1-Fig. 6, the bottom of this plug housing 1 is also provided with circular arc base 7.The design of circular arc base 7, from appearance, product is more mellow and fuller, and from security, the base of slide fastener makes arc surface into from plane, makes it remove four wedge angles, makes slide fastener safer, can not hurt health.
Further, as a kind of optimal way, these latch 3 numbers are two and are symmetrical arranged.
Further, as a kind of optimal way, this latch 3 be shaped as triangle.Leg contacts with sidewall and the bottom surface of pin hole respectively, keeps its stressed steadiness, and the sidewall of triangle end face and pin hole both sides is adjacent to, and has further strengthened the supporting role to latch 2
Further, as a kind of optimal way, be also provided with fluting 8 on this pin hole 9, the bottom surface of this fluting 8 is higher than the bottom surface of described pin hole 9.Prevent that latch 2 from skidding off, keep its end stressed evenly.
Further, as a kind of optimal way, the bottom surface of this fluting 8 is higher than the center of arc position of described circular arc base 7.Guarantee the thickness of base, prevent plug housing 1 bottom cracking.
Further, as a kind of optimal way, locking face 4 numbers on this latch 2 are 2.Corresponding with latch 3.
Further, as a kind of optimal way, the angle of this chute wall 6 is 5-8 degree.In general, zipper latch seat major part is all to start to split from position bottom, therefore allows strap more press from both sides between two chute wall 6 tighter, and what in position bottom, press from both sides is tighter.Contact area between chute wall 6 and strap is larger simultaneously.
Further, as a kind of optimal way, this plug housing 1 and latch 2 are formed in one.Do not need to process in addition perforate, make production cost lower.
Although the utility model with preferred embodiment openly as above; but it is not for limiting the utility model; any those skilled in the art are not within departing from spirit and scope of the present utility model; can make possible change and modification, the scope that therefore protection domain of the present utility model should be defined with the utility model claim is as the criterion.
