Abstract

The utility model relates to a zipper head which comprises a pulling head, wherein two fixing frames are arranged on the front end and the back end of the pulling head. A groove is arranged in the middle of the extending end of the fixing frame in the front end. A cap is covered above the pulling head from upside. The surfaces of the inside and the end lean against the corresponding face of the fixing frame. The cap and the fixing frame in the front end are fixed by a fixed pin. A spring sheet extends from the front end of the cap to the middle of the pulling head through the front end of the pulling head and into the pulling head from a through-hole which is arranged in the middle of the pulling head. A pulling sheet extends from the lower side of the spring sheet to the outer side of the cap. The utility model is of simple structure and long life-span, further, the springy strength of the spring sheet is increased.

Description

Slider of zipper fastener

The utility model relates to a kind of slider of zipper fastener.

Slider of zipper fastener is the important component part of slide fastener, and the performance of whole slide fastener is played a major role.Existing slider of zipper fastener is of all kinds, but ubiquity slider of zipper fastener reed intensity and the defective that the life-span of slider of zipper fastener can not effectively combine, and that is to say, its life-span is just short when the intensity of the reed of slider of zipper fastener guarantees, and when having guaranteed the life-span of slider of zipper fastener, the intensity of its reed just can not reach requirement.

The purpose of this utility model is that the above-mentioned defective that overcomes prior art provides a kind of slider of zipper fastener reed intensity height long slider of zipper fastener of life-span of slider of zipper fastener simultaneously.

The utility model comprises pull head, before above pull head, back two ends are provided with "T"-shaped fixed mount, the "T"-shaped fixed mount external part of front end is provided with groove than long and centre, cap is " U " shape and is covered on pull head by the top, its surface inner and end is resisted against on the corresponding face of fixed mount, simultaneously cap with fix by steady pin at the fixed mount of front end, spring leaf is extended out at front end by cap, be serpentine and reach the middle part by the pull head front end, and pass the through hole that is located at pull head middle part and enter in the pull head, pulling-on piece is passed and is reached the outside of cap by the below of spring leaf.

By said structure, cap can be securely fixed on the pull head, and spring leaf and cap integrative-structure make structure of the present utility model more become simply simultaneously, have prolonged service life, and the elastic strength of spring leaf is strengthened.

Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.

Fig. 1: the configuration diagram of present embodiment;

The A-A view of Fig. 2: Fig. 1.

As shown in the figure, present embodiment comprises pull head 1, before above pull head 1, back two ends are provided with "T"-shaped fixed mount 2 separately, 3, wherein the external part of the fixed mount 2 of front end is provided with groove than length and in the centre of external part, cap 4 is " U " shape by

fixed mount

2,3 top is covered on pull head 1, cap 4 the surfaces inner and end are resisted against fixed mount 2, on the 3 corresponding faces, the four edges of cap 4 on four angles just just is stuck in fixed mount 2 like this, on 3 four interior right angles that form, cap 4 is fixing by steady pin 5 with the fixed mount 2 of front end simultaneously, so just fully cap 4 is fixed on the pull head 1, this structure makes cap convenient fixing and fixation on pull head, spring leaf 6 and cap 4 one and extend out by the front end of cap 4, be serpentine and reach the middle part downwards backward from the groove of the fixed mount 2 of pull head 1 front end, extension is downwards earlier turned and is extended the extension downwards of turning again to the back upper place, and pass the through hole 7 that is located at pull head 1 middle part and enter in the pull head 1, the structure of spring leaf and cap one reduces the part number of slider of zipper fastener, whole structure becomes simple, make processing, easy to assembly, and depend primarily on material and its thickness of spring leaf by the elastic strength of this structure spring leaf, can strengthen the elastic strength of spring leaf greatly, make spring leaf can lock zipper teeth better in use, simultaneously because pulling-on piece 8 passes and reach the outside of cap 4 by the below of spring leaf 6, block 4 is provided with opening so that pulling-on piece 8 passes from cap 4 in the position that pulling-on piece 8 passes spring leaf 6.The groove corresponding position of the surperficial front end fixed mount 2 above pull head 1 is provided with circular groove, turning after spring leaf 6 gets off from the groove of front end fixed mount 2 is trapped in the circular groove, and the curved shape of the shape of circular groove and spring leaf 6 matches substantially.Thereby this structure can make spring leaf avoid running into the regular event that the steady pin that connects cap and fixed mount influences spring leaf on the one hand as far as possible, circular groove can prop up spring leaf moving down of spring leaf is restricted on the other hand, and spring leaf is played the role of positioning.
