Abstract

The utility model discloses a modified structure of an opening zipper slide, consists of a cloth belt, chain teeth, a socket and an intubation, wherein, the socket, the intubation are respectively arranged on the bottom end of the cloth belt on two sides, the socket is provided with an opening at the side opposite to the intubation, the bottom ends of the socket and the intubation respectively adaptably extend out of the lower part of the cloth belt bottom end, and the socket opening parts which extend out of the bottom end of the cloth belt are respectively provided with a sealing head, the sealing head extends and closes the socket opening along the bottom end of the socket opening. Thereby, when the intubation is inserted in the socket, the part of the intubation extending out of the cloth belt evenly extends into the sealing head of the socket, thus the combination strength of the socket and the intubation is greatly improved, the intubation cannot break away from the socket no matter how strong the tensile force is, service life of the zipper slide is lengthened, the utility model is more suitable in application environments requiring stronger tensile forces, has simple structure, convenient manufacture, hardly increases manufacturing cost.

Description

The improvement structure of open-type slide fastener

Technical field

The utility model relates to a kind of slide fastener, especially the open-type slide fastener.

Background technology

Existing open-type slide fastener, as shown in Figure 1 and Figure 2, comprise strap 1 ', chain tooth 2 ', socket 3 ' and intubate 4 ', wherein, socket 3 ', intubate 4 ' are located at the bottom of both sides strap 1 ' respectively, and the bottom of socket 3 ', intubate 4 ' is all concordant with strap 1 ', and socket 3 ' is provided with opening 31 ' in the face of a side of intubate 4 ', inserts for the strap 1 ' that links to each other with intubate 4 '.When this open-type slide fastener uses, as shown in Figure 2, intubate 4 ' is inserted in the socket 3 ', and the strap 1 ' that links to each other with intubate 4 ' inserts this structure along opening 31 ', when pulling force is big, intubate 4 ' is easy to shake off out in socket 3 ', and intubate 4 ' is relatively poor with the bond strength of socket 3 ', and service life is shorter, for some environments for use that needs big stretching resistance, then can't use.

Summary of the invention

The purpose of this utility model provides the bond strength height of a kind of intubate and socket, the open-type slide fastener of long service life.

The technical solution of the utility model is such: the improvement structure of open-type slide fastener, comprise strap, chain tooth, socket and intubate, wherein, socket, intubate are located at the bottom of both sides strap respectively, socket surface is provided with opening to a side of intubate, the bottom homogeneous phase of socket, intubate stretches out strap bottom below adaptedly, and the part that receptacle openings is stretched out the strap bottom is provided with block.

Above-mentioned block and above-mentioned socket are one-body molded, for extend the end socket of sealing along the bottom of above-mentioned receptacle openings.

The improvement structure of the utility model open-type slide fastener, the bottom homogeneous phase of socket, intubate are stretched out strap bottom below adaptedly, and the part that receptacle openings is stretched out the strap bottom is provided with the end socket that extends sealing along the bottom of receptacle openings.Like this, when intubate is inserted in the socket, intubate is stretched out the part of strap and is stretched just in the end socket that places above-mentioned socket, like this, the bond strength of socket and intubate improves greatly, and no matter great pulling force also can't be shaken off out from socket with intubate, prolong the service life of slide fastener, more be applicable to the environment for use that some need big stretching resistance.And it is simple in structure, easy to process, increases manufacturing cost hardly.

The specific embodiment

The improvement structure of the utility model open-type slide fastener, as shown in Figure 3, comprise strap 1, chain tooth 2, socket 3 and intubate 4, wherein, socket 3, intubate 4 are located at the bottom of both sides strap 1 respectively, socket 3 is provided with opening 31 in the face of a side of intubate 4, and the bottom homogeneous phase of socket 3, intubate 4 stretches out below, strap 1 bottom adaptedly, and the part that receptacle openings 31 is stretched out the strap bottom is provided with end socket 311.

The improvement structure of the utility model open-type slide fastener, the bottom homogeneous phase of socket 3, intubate 4 are stretched out strap bottom below adaptedly, and the part that receptacle openings 31 is stretched out the strap bottom is provided with the end socket 311 that extends sealing along the bottom of receptacle openings 31.Like this, when intubate 4 is inserted in the socket 3, intubate 4 is stretched out the part of strap 1 and is stretched just in the end socket 311 that places socket 3, like this, socket 3 improves greatly with the bond strength of intubate 4, and no matter great pulling force also can't be shaken off out from socket 3 with intubate 4, prolong the service life of slide fastener, more be applicable to the environment for use that some need big stretching resistance.And it is simple in structure, easy to process, increases manufacturing cost hardly.

Claims
