Abstract
The invention provides an elastic zipper tapered end which belongs to closed locking devices. The elastic zipper tapered end comprises an upper cover, a lower cover, a handle, a double-screw bolt, a clamping block and a poking sheet, wherein the upper surface of the lower cover is provided with a pylon which is arranged in the middle place of the lip of the lower cover, a threaded hole is formed in the upper cover and vertically penetrates through the upper cover and the pylon, and the double-screw bolt is screwed into the threaded hole so as to connect the upper cover with the lower cover. A ladder pylon is arranged on the lower cover, the through hole is formed in the upper cover which is provided with the clamping block, so that the upper cover and the lower cover of the zipper tapered end can be relatively separated in an upper and down manner, and when the zipper tapered end is normally used, the upper cover and the lower cover are firmly combined, and the pulling is not influenced; once being fixed, the double-screw bolt does not need to be rotated due to the design of the clamping clock, when the upper cover and the lower cover are loosened and fastened, the clamping block only needs to be manually rotated without needing any tools; and as the double-screw bolt does not need to be rotated, the elastic zipper tapered end provided by the invention is long in service life.
Description
Technical field:
The present invention relates to a kind of closed shutoff device, but particularly a kind of degree of tightness slide fastener tapered end.
Background technology:
Zip comes out century-old excessively, it brings people simultaneously easily, also exist problem, wherein the most outstanding also be everyone may run into be exactly: when spurring zipper head, the selvedge of clothing etc. is involved in the zipper head accidentally, and zipper head does not advance not move back yet afterwards, many times need to use destructive rough power, slide fastener more of poor quality may be just bad at once, namely is temporarily not bad, often also be difficult to guarantee.
Among the ZL200720076908.6 in the disclosed scheme, screw in and be screwed into loam cake from the zipper head lower cover with double-screw bolt, thereby make zipper head upper and lower covers relative fixed.This scheme can be implemented in theory, but can't use in actual the use at all, single can only make upper and lower covers in the stud shaft relative fixed that makes progress with double-screw bolt, can't make upper and lower covers in the plane of joint relative fixed, and further, this structure is easy to make upper and lower covers to slide relatively, will make zipper head be difficult to pulling in case slide.Secondly, when breaking down, this scheme need be used small-bore screwdriver, but can not everyone join handle with oneself in the daily life.
Summary of the invention:
Given this, but be necessary to design a kind of sound construction reliable, can be not by the degree of tightness slide fastener tapered end of loosening tool.
But a kind of degree of tightness slide fastener tapered end comprises: loam cake, lower cover, draw, double-screw bolt; Wherein, loam cake and lower cover all are the left-right symmetry structure separately, and the wideer end of loam cake and lower cover is respectively loam cake lip and lower cover lip, and during use, slide fastener chain separated from each other enters between loam cake lip and lower cover lip, come out from the other end in engaged back.The lower cover upper surface is provided with pylon and pylon is positioned at centre position, lower cover lip place, vertically run through loam cake, pylon being covered with a screwed hole, double-screw bolt screws in this screwed hole to connect loam cake and lower cover, be provided with a bridge of the nose in the symmetrical centerline of loam cake upper surface, the centre of the bridge of the nose and loam cake contact-making surface is provided with groove, draws flexibly connecting by this groove and loam cake.
Pylon is stepped, comprises first ladder that links to each other with lower cover and second ladder that is positioned on first ladder, and the cross section of second ladder can not be circular less than first ladder and cross section; Second ladder over against the loam cake place be the fixing hole that the cross section of geomery and second ladder is complementary, the height of second ladder stretches into less than the hole depth of fixing hole and second ladder loam cake lower surface and the first ladder table top is offseted; But degree of tightness slide fastener tapered end also comprises clamping block, clamping block is stepped, part towards loam cake is clamping block first ladder, the part of loam cake is clamping block second ladder dorsad, the cross section of clamping block first ladder is complementary less than clamping block second ladder and shape of cross section size and fixing hole, have through hole at clamping block, aforementioned double-screw bolt passes this through hole and loam cake, lower cover is fastening.
After double-screw bolt screwed in and fixes, double-screw bolt no longer relatively rotated with zipper head; During normal the use, clamping block first ladder is positioned at outside the fixing hole, and after zipper head was clamped the clothes selvedge, the spin locking piece screwed in fixing hole with clamping block first ladder, at this moment, mobilizable space is arranged between the upper and lower cover, can take out easily by the folder foreign matter.
Preferably, clamping block links to each other with plectrum, and plectrum is longer than clamping block, by stirring plectrum spin locking piece more easily.
Preferably, have rectangular slot at the clamping block second ladder upper surface, by double-screw bolt plectrum is arranged fixedly in the groove, the plectrum width equals the rectangular slot groove width.
Preferably, the plane exceeds the rectangular slot bottom surface on the bridge of the nose, and the plane has rectangular channel towards the part of loam cake lip on the bridge of the nose, rectangular channel groove width and plectrum width coupling.When normal use, the non-rotating end of plectrum is dialled in rectangular channel can prevent from rotating accidentally plectrum.
The present invention by under cover design ladder pylon, have through hole and be provided with clamping block at loam cake, make the upper and lower cover of zipper head not only can relatively separate up and down, and when normal the use in conjunction with firmly, can not influence pulling; The design of clamping block just need not turn again after making double-screw bolt in a single day fix, and when loosening, tighten upper and lower covers, only needs the hand rotation clamping block, need not lodge any instrument; Simultaneously, because without the turn double-screw bolt, zipper head design service life of the present invention is longer.
