End under a kind of slide fastener
Technical field
The invention belongs to the slide fastener field, particularly a kind of slide fastener in use plays under the slide fastener of spacing and anticreep effect and ends.
Background technology
At present, the slide fastener that occurs in market mainly contains nylon zipper and metal zip fastener, by strap, tooth, slider of zipper fastener, go up and end, only form down, for nylon zipper in use joint very easily go out from last anti-avulsion, also be easy in the time of unmindful be eaten by mistake by child; In addition, this nylon zipper go up to end and down only through the injection machine injection moulding, disposable injection moulding is only with slide fastener of injection moulding, and going up after the injection moulding ended and can residually there be unnecessary raw material in the following edge of ending, these residual raw materials scrape user's finger easily, also have huge injection machine to take the big quantity space of whole slide fastener production line, so not only there is the unsafe factor that goes up of using in nylon zipper, and have the coarse shortcoming of production, also there is the defective that production efficiency is low and production process is too limited to.Metal zip fastener not only exists and produces the high problem of metal material cost when producing upper and lower ending, and exists roughly, and the corner angle of bending place are too sharp, scrape user's defective easily.
Summary of the invention
In order to address the above problem, to have the object of the present invention is to provide that a kind of structure is simple more, production efficiency is high, energy-conservation, and can reduce under the slide fastener of slide fastener production cost and end.
For achieving the above object, the technical solution adopted in the present invention is: end under a kind of slide fastener, described ending down to being arranged on two teeth between the strap and the tooth that staggers on two straps can being combined and can prevent the U-shaped locating clip that slider of zipper fastener is deviate from, U-shaped locating clip comprises the shape limited block of spreading the wings that is clipped on the tooth and the use of slider of zipper fastener is played position-limiting action, center below the shape limited block of spreading the wings is integrally formed with to cooperatively interact with the shape limited block of spreading the wings and clamps the L type fixture block of tooth and strap, and U-shaped locating clip comprises the shape limited block of spreading the wings that is clipped on the tooth and the use of slider of zipper fastener is played position-limiting action, center below the shape limited block of spreading the wings is integrally formed with to cooperatively interact with the shape limited block of spreading the wings and clamps the L type fixture block of tooth and strap, and be provided with the triangle boss that two straps that combine can be separated at the turning of L type fixture block.
More excellent, described bottom of spreading the wings the shape limited block can be arcuation or flat bottom.
More excellent, bottom the right and left of the described shape limited block of spreading the wings is respectively equipped with staggered recess.
More excellent, described L type fixture block comprises perpendicular to the vertical rod of the shape limited block bottom of spreading the wings, parallel and perpendicular to the bottom bar of vertical rod bottom the shape limited block of spreading the wings.
More excellent, described bottom bar is less than the shape limited block bottom of spreading the wings.
More excellent, described bottom bar is wide with the shape limited block bottom of spreading the wings.
More excellent, the described shape limited block of spreading the wings, L type fixture block are formed in one between the two.
More excellent, be formed in one between the described shape limited block of spreading the wings, L type fixture block, the triangle boss three.
After adopting technique scheme, owing to end down to being arranged on two teeth between the strap and the tooth that staggers on two straps can being combined the U-shaped locating clip that prevents that slider of zipper fastener from deviating from, spread the wings wherein that shape limited block, L type fixture block are formed in one between the two or the shape limited block of spreading the wings, L type fixture block, triangle boss three between be formed in one, so it is simpler to draw down the structure of ending; Again since down the production that ends is disposable can injection moulding 20, with following tooth and the strap that only is installed to slide fastener that injection moulding is finished, namely disposablely can produce 20 slide fasteners, compared with prior art, not only improve the efficient height of producing, and the injection machine utilization rate has been reduced, realized energy-saving effect; Also because to the minimizing of injection machine quantity, the also corresponding minimizing of space that the slide fastener apparatus for production line is shared, this has greatly reduced the production cost of slide fastener.

The specific embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.
To shown in Figure 6, end described ending down to being arranged on two teeth between the strap and the tooth that staggers on two straps can being combined and can prevent the U-shaped locating clip 1 that slider of zipper fastener is deviate under a kind of slide fastener as Fig. 1.As shown in Figure 2, U-shaped locating clip 1 comprises being clipped on the tooth and the use of slider of zipper fastener being played the shape limited block 11 of spreading the wings of position-limiting action, center below the shape limited block 11 of spreading the wings and is integrally formed with to cooperatively interact with the shape limited block 11 of spreading the wings and clamps the L type fixture block 12 of tooth and strap; As shown in Figure 3, U-shaped locating clip 1 comprise be clipped on the tooth and to the use of slider of zipper fastener play the shape limited block 11 of spreading the wings of position-limiting action, center below the shape limited block 11 of spreading the wings is integrally formed with the shape limited block 11 of spreading the wings cooperatively interacts and clamp the L type fixture block 12 of tooth and strap and be provided with the triangle boss 13 that two straps that combine can be separated at the turning of L type fixture block 12; Shown in Fig. 1 to 6, the bottom of the shape limited block 11 of spreading the wings can be the bottom of arcuation 14 or flat 15; As shown in Figure 1, spread the wings bottom the right and left of shape limited block 11 is respectively equipped with staggered recess 16; Shown in Fig. 1 to 6, L type fixture block 12 comprises perpendicular to the vertical rod 17 of shape limited block 11 bottoms of spreading the wings, parallel with shape limited block 11 bottoms of spreading the wings and perpendicular to the bottom bar 18 of vertical rod 17, bottom bar is less than shape limited block 11 bottoms of spreading the wings, bottom bar is wide with shape limited block 11 bottoms of spreading the wings, the shape limited block 11 of spreading the wings, L type fixture block 12 are formed in one between the two or the shape limited block 11 of spreading the wings, L type fixture block 12, triangle boss 13 threes between be formed in one.During production, the following below that only clips to the slide fastener tooth respectively that disposable injection formed is a plurality of, following only clamping that the recycling ultrasonic wave equipment of welding will be clipped on the slide fastener tooth gets final product.
Above-described only is the preferred embodiment of ending under the slide fastener of the present invention; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design; can also make some distortion and improvement, these all belong to protection scope of the present invention.
