Description
Technical Field
The utility model belongs to the technical field of the zip fastener technique and specifically relates to a dead formula plastic steel zip fastener of self-lubricating anti-sticking is related to.
Background
The plastic steel zipper is firm and durable, and has been widely applied to various articles in daily life, and the plastic steel zipper in the current market is basically formed by mutually meshing whole zipper teeth formed by injection molding, or the zipper is made of different appearance models and different materials to meet the market demand; however, the existing plastic-steel zipper has high hardness, and the contact positions of the side walls of the zipper teeth of the zipper are vertical planes, so that the zipper is not smooth in the meshing or unzipping process, the zipper needs to be straightened or can be torn off with great force, and if the zipper teeth are easily torn off due to the excessive force, the zipper is damaged; therefore, it is necessary to provide an anti-seizing plastic-steel zipper to solve the above problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a self-lubricating anti-sticking formula plastic steel zip fastener to the not enough that prior art exists to solve above-mentioned problem.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is:
a self-lubricating anti-blocking plastic steel zipper comprises a first zipper strip, a zipper tooth row arranged on the first zipper strip, a second zipper strip and a zipper tooth row arranged on the second zipper strip; the chain tooth monomers on the first zipper tape and the chain tooth monomers on the second zipper tape are arranged at intervals and are mutually meshed or separated; the zipper tooth comprises a tooth body part and a tooth tip part, the tooth body part and the tooth tip part are connected through a narrowing part, and the left side surface and the right side surface of the narrowing part are respectively provided with an engaging part which extends outwards and horizontally; cusp portion is including the last plane portion that is oval form, go up the edge slant downwardly extending of plane portion, form smooth with the mutual paired curved surface portion of constriction, the one end that the body portion was kept away from to cusp portion still be equipped with the mutual snap-fit's of interlock portion interlock groove.
In a further technical scheme, a clamping opening part used for being fixedly assembled with the zipper in a connecting way is arranged on the side surface of the tooth body part, and an arc-shaped clamping groove is formed in the bottom of the clamping opening part.
In a further technical scheme, the joint of the upper plane part and the curved surface part is rounded.
In a further technical scheme, the upper surface of the tooth body part is in an oval shape and is matched with the upper plane part to form a gourd shape.
After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model designs the side surface of the upper plane part as the curved surface part extending downwards, and in the meshing process, because the friction between the curved surface parts is small, the adjacent zipper teeth can be easily meshed and paired together, thereby preventing the zipper from being blocked; the oval upper plane enables the zipper to automatically slide in place in the meshing process, the zipper has a self-lubricating function, and the zipper can be easily meshed or unzipped.
Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a schematic view of the fastener element of the present invention;
fig. 3 is a schematic structural view of the fastener element of the present invention.
Detailed Description
The following are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby.
A self-lubricating anti-seize plastic steel zipper as shown in fig. 1 to 3, comprising a first zipper strip 1, a fastener element row arranged on the first zipper strip 1, a second zipper strip 2 and a fastener element row arranged on the second zipper strip 2; the single elements 3 on the first zipper strip 1 and the single elements 3 on the second zipper strip 2 are arranged at intervals and mutually engaged or separated.
The zipper element 3 comprises a body part 31 and a cusp part 32, the body part 31 and the cusp part 32 are connected through a narrowing part 33, and both the left side surface and the right side surface of the narrowing part 33 are provided with engaging parts 33a which extend outwards and horizontally; the cusp 32 is including the last plane portion 32a that is oval form, go up the edge slant downwardly extending of plane portion 32a, form smooth with the mutual paired curved surface portion 34 of constriction 33, go up plane portion 32a with the junction rounding off of curved surface portion 34, the cusp 32 one end of keeping away from shaft portion 31 still be equipped with the mutual snap-fit's of interlock portion 33a interlock groove 32 b.
When the element row on the first fastener tape 1 and the element row on the second fastener tape start to be engaged with each other under the action of the fastener head, the elements 3 on the first fastener tape 1 are embedded into the narrowing portions 33 of the elements 3 of the second fastener tape 2 matched with the elements, and are finally engaged through the matching between the engaging portions 33a and the engaging grooves 32b, in the engaging process, because the friction between the curved surface portions 34 is small, the adjacent elements 3 can be easily engaged and matched together, and the upper plane portions of the oval shapes enable the slide fastener to automatically slide in place in the engaging process, so that the self-lubricating effect is realized.
In this embodiment, the side surface of the body portion 31 has a mouth portion 31a for fixedly assembling with the zipper, and the bottom of the mouth portion 31a is provided with an arc-shaped clipping groove, so that the zipper teeth 3 are clipped on the zipper through the arc-shaped clipping groove and are not easy to fall off; the upper surface of the tooth part 31 is elliptical and is matched with the upper plane part 32a to form a gourd shape, so that the whole body is more attractive.
The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
