Abstract
The utility model relates to an elastic zipper lock head and belongs to closing locking devices. The elastic zipper lock head comprises an upper cover, a lower cover, a pulling handle, a double-screw bolt, a locking block and a shifting piece. A column platform is arranged on the upper surface of the lower cover and located in the middle position of the lip portion of the lower cover. A threaded hole is formed in the upper cover and penetrates through the upper cover and the column platform perpendicularly. The double-screw bolt is screwed in the threaded hole so that the upper cover and the lower cover can be connected. The step column platform is arranged on the lower cover, a through hole is formed in the upper cover and a locking block is arranged so that the upper cover and the lower cover of the zipper lock head can be oppositely and vertically departed and be combined firmly in the normal use, and pulling is not influenced. The design of the locking block enables that the double-screw bolt does not need to be screwed once being fixed. When the upper cover and the lower cover are loosened and tightened, the locking block just needs to be manually rotated without the help of any tool. Meanwhile, the double-screw bolt does not need to be screwed, so that the elastic zipper lock head is longer in service life.
Description
Technical field:
The utility model relates to a kind of closed shutoff device, but particularly a kind of degree of tightness zipper lock head.
Background technology:
Zip comes out excessively century-old, 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 the zipper head upper and lower covers relatively fixing.This scheme can be implemented in theory, but can't use in actual the use at all, alone double-screw bolt can only make upper and lower covers upwards relatively fixing at stud shaft, can't make upper and lower covers relatively fixing on the plane of joint, and further, this structure is easy to make the upper and lower covers relative sliding, will make zipper head be difficult to pulling in case slide.Secondly, when breaking down, this scheme need to be used small-bore screwdriver, but can not everyone join with oneself handle 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 zipper lock head of loosening tool.
But a kind of degree of tightness zipper lock head 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 wider 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, engaged after from the other end out.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 being flexibly connected by this groove and loam cake.
Pylon is stepped, comprises the first ladder that links to each other with lower cover and the second ladder that is positioned on the first ladder, and the cross section of the second ladder can not be circular less than the first ladder and cross section; The second ladder over against the loam cake place be the fixing hole that the cross section of geomery and the second ladder is complementary, the height of the second ladder stretches into less than the hole depth of fixing hole and the second ladder loam cake lower surface and the first ladder table top is offseted; But the degree of tightness zipper lock head also comprises clamping block, clamping block is stepped, part towards loam cake is clamping block the first ladder, the part of loam cake is clamping block the second ladder dorsad, the cross section of clamping block the first ladder is complementary less than clamping block the 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 the 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 the 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 more easily spin locking piece of plectrum.
Preferably, have rectangular slot at clamping block the second ladder upper surface, be fixed with plectrum by double-screw bolt 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 accidentally rotating plectrum.
The utility model by under cover design ladder pylon, have through hole and be provided with clamping block at loam cake so that 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 affect pulling; The design of clamping block when loosening, tighten upper and lower covers, only needs the hand rotation clamping block so that double-screw bolt just need not again turn after in a single day fixing, and need not lodge any instrument; Simultaneously, because without the turn double-screw bolt, zipper head design service life of the present utility model is longer.
