Abstract

A zipper head structure relates to the zipper technological field, in particular to a zipper head structure with reliable use and low cost. The technical proposal is that: the other hook end of a lockpin of a tensioning head is arranged in a slot pore of a tensioning head body, a cuniform clearance is arranged between the end face and the walls of the slot pore; an spring sheet is in a hook shape, one end of the spring sheet is fixed to the tensioning head body while the other end is pressed on the middle face of the lockpin of the tensioning head. The lockpin of the tensioning head of the utility model has reliable reposition, simple structure and low cost.

Description

The slider of zipper fastener structure

Technical field:

The utility model relates to the slide fastener technical field, refers in particular to a kind of service-strong slider of zipper fastener structure.

Background technology:

Existing slider of zipper fastener structure protrudes out two boss 51 on the drawing head body 5 shown in accompanying drawing 7,8,9, pull head bayonet catch 2 places between the boss 51, and is connected with boss 51 by axle 3; Spring 4 one ends place in the slotted eye 52 of drawing head body 5, and the other end withstands the end face 21 of pull head bayonet catch 2 one ends, are with pulling-on piece button circle 1 on the gib head 22 of pull head bayonet catch 2 other ends, and the hole 53 that gib head 22 terminations can be passed on the drawing head body 5 fastens with slide fastener; When pulling-on piece button circle 1 was stretched, gib head 22 withdrawed from from the groove 54 of drawing head body 5, broke away from slide fastener, made that drawing head body 5 can slippage on slide fastener, with the slide fastener drawing or separately; When end face 21 withstood the table top 55 of drawing head body 5, pull head bayonet catch 2 no longer rotated; At this moment, spring 4 compressions; After pulling-on piece button circle 1 was unclamped horizontal, spring 4 elongations by compression resetted pull head bayonet catch 2, thereby gib head 22 and slide fastener are hooked together again, and slide fastener is sealed; In this kind structure,, after spraying paint, clung by lacquer very easily, and can't stretch, make the reliability of using greatly reduce because spring 4 is less; In addition, pull head bayonet catch 2 needs to connect by axle 3, and its part increases, and it is more to produce assembly technology, and cost is higher.

Summary of the invention:

The purpose of this utility model is to provide the slider of zipper fastener that a kind of serviceability is reliable, simple in structure, cost is low structure.

The utility model is achieved by the following technical solution: another hook end of pull head bayonet catch places the slotted eye of drawing head body, and a wedge gap is arranged between the wall of its end face and slotted eye; Spring leaf is hook-shaped, the one end fixing with drawing head body on, the other end is pressed on the middle part face of pull head bayonet catch; There are two restraining spring sheets to stretch the spring riveted convex surface of degree on the drawing head body; The hook end termination of pull head bayonet catch is spherical; Spring leaf is

Shape.

The utility model pull head bayonet catch relies on the restoring force of spring leaf to reset, and it resets reliably; And the pull head bayonet catch by with spring leaf and drawing head body between cooperate between fixing, need not axle to connect; Relative existing structure, part reduces, and cost is relatively low, and the reliability of using greatly improves.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further specified:

Accompanying drawing 1 the utility model front view;

Accompanying drawing 2 is the utility model A-A cutaway view;

Accompanying drawing 3 is the utility model user mode front view;

Accompanying drawing 4 is the utility model user mode A-A cutaway view;

Accompanying drawing 5 is the utility model spring leaf 6 vertical views;

Accompanying drawing 6 is the utility model spring leaf 6 front views;

Accompanying drawing 7 is existing slider of zipper fastener vertical view;

Accompanying drawing 8 is existing slider of zipper fastener front view;

The specific embodiment:

See accompanying drawing 1～4, the utility model includes pulling-on piece button circle 1, pull head bayonet catch 2, drawing head body 5, spring leaf 6, and pulling-on piece button circle 1 is placed on the gib head 22 of pull head bayonet catch 2, and the hole 53 that gib head 22 passes on the drawing head body 5 is placed in the groove 54; Pull head bayonet catch 2 another hook ends 23 place the slotted eye 52 of drawing

head body

5, and 56 on the wall of its end face 24 and slotted eye has a wedge gap; Spring leaf 6 is hook-shaped, the one end fixing with drawing head body 5 on, the other end is pressed on the middle part face 25 of pull head bayonet catch 2; There are two restraining spring sheets 6 to stretch the spring riveted convex surface 57 of degree on the drawing head body 5; Hook end 23 terminations of pull head bayonet catch 2 are spherical; Spring leaf 6 is

Shape.

When using the utility model, with pulling-on piece button circle 1 horizontal, the hole 53 that gib head 22 passes on the drawing head body 5 is placed in the groove 54, hooks together with slide fastener, makes slide fastener sealed; After pulling-on piece button circle 1 is erect pull-up, gib head 22 is drawn out outside the groove 54, spur the utility model, can realize the opening and closing of slide fastener, this moment, spring leaf 6 was opened, when an end that contacts with pull head bayonet catch 2 when spring leaf 6 withstands convex surface 57, spring leaf 6 no longer opens, unclamp pulling-on piece button circle 1 after, spring leaf 6 resets, pull head bayonet catch 2 can be resetted, and make its gib head 22 hook slide fastener.
