Description

A kind of slide fastener self-locked draught part

Technical field

The utility model relates to a kind of slide fastener, particularly a kind of slide fastener self-locked draught part.

Background technology

Apply on May 6th, 2011 the applicant, and with on November 7th, 2012 invention disclosed patent CN102763941A, disclose a kind of slide fastener self-locked draught part, comprise cap, flexible member, horse hook and slide body.This horse hook is provided with location division, and this flexible member is removably connected on the location division of this horse hook.Disclose this location division further to limit this flexible member and move along the width of this horse hook.But this slide fastener also exists problem, namely horse hook moves upward and to be limited by shell fragment, moves left and right and is also limited by shell fragment, but moves downward and be not defined, thus it is excessively dark often to occur thrusting slide fastener, effectively cannot depart from slide fastener when pulling, and causes pulling having some setbacks.

Utility model content

The purpose of this utility model is to solve the problems of the prior art, and provide a kind of slide fastener self-locked draught part, horse hook is moved up and down and is all limited, the length of stretching out inside pull head body is fixed, the self-locking of pull head and pull more smooth and easy.

For reaching above-mentioned purpose, the utility model adopts following technical scheme:

A kind of slide fastener self-locked draught part, comprises pull head body, pulling-on piece, shell fragment, horse hook, cap; Pull head body upper plate is provided with boss, cap and boss fasten, and shell fragment is fixed in cap or is fixed between cap and pull head boss, forms groove in the middle of boss, horse hook to be placed in groove and to contact at shell fragment lower surface, and pulling-on piece draw ring is through passing cap under horse hook; It is characterized in that: perforate on shell fragment, horse hook is provided with connector, through perforate on shell fragment, hooks shell fragment upper surface.

Technical scheme described in the utility model is relative to prior art, and the beneficial effect obtained is:

Because horse hook contacts at shell fragment lower surface, therefore horse hook moves upward and to be limited by shell fragment; And horse hook connector hooks shell fragment upper surface through perforate on shell fragment, therefore horse hook moves downward and is also limited by shell fragment, thus horse hook is moved up and down all be limited, and the length of stretching out inside pull head body is fixed, the self-locking of pull head and pull more smooth and easy.
