Abstract

The utility model relates to a pulling sheet structure of a zipper. A combined head has a plastic metal structure; the front part of the combined head is a quadrate ring body; the back end part of the ring body is provided with a U-shaped clamping body; a plurality of saw teeth are arranged on both sides of the inner part of the clamping body in a relatively staggered mode at intervals; one end of the pulling sheet is arranged in the clamping body at the back end of the combined head; the saw teeth in the clamping body firmly clamp and hold the pulling sheet for fixation; the ring body on the front part of the combined head is hooked on a hooking ring of a chain body in a penetrating mode. The utility model has the effects that the combined head has a firm and durable structure, the pulling sheet is easy to pull and is not easy to deform, and the service life of the pulling sheet is extended.

Description

The pulling-on piece structure of slide fastener

The utility model relates to slide fastener, refers in particular to a kind of pulling-on piece structure of slide fastener.

Slide fastener commonly used at present as shown in Figure 1-Figure 3, comprise chain body 10, serobila 20, coupling collar 30 and pulling-on piece 40, the upper surface of its serobila 20 the place ahead central authorities is provided with backward ostiolately colludes with encircling 21, two outer side edges of below respectively are provided with button and become attached to 22, two buttons are become attached to 22 and are detained two inner side edges that knot is fixed in chain body 10 respectively, the ring body 31 of the place ahead squarely of coupling collar 30, and the rear end of ring body 31 is provided with the ostiolate shackle 32 in below, pulling-on piece 40 is rectangular lamellar body, and the place ahead central authorities are provided with combined hole 41.During combination, earlier the ring body 31 of coupling collar 30 is placed collude with in serobila 20 collude with encircling on 21, the shackle 32 of colluding with encircling 21 rear ends is worn in the combined hole 41 of people's pulling-on piece 40 and is colluded with fixing, and 40 of serobila 20 and pulling-on pieces are chained mutually by coupling collar 30.Its major defect is:

When 1, driving coupling collar and serobila when application of force pulling pulling-on piece, less because of the area of colluding with contacting of its coupling collar, the point of application concentrates on the coupling collar, easily causes the coupling collar distortion, shortens its service life.

2, because shackle itself is less, its operation of colluding with making up is not easy.

3, because of pulling-on piece commonly used is a metal structure, its decoration and reflecting effect are relatively poor.

Main purpose of the present utility model is to provide a kind of pulling-on piece structure of slide fastener, firmly with the pulling-on piece clamping, overcome the drawback of prior art by the sawtooth in the clamp of joint head rear end, it is sturdy and durable to reach joint head, pulling is difficult for deforming and improving the purpose in service life easily.

The purpose of this utility model is achieved in that, a kind of pulling-on piece of slide fastener structure, comprise chain body, serobila and pulling-on piece, the upper surface of its serobila the place ahead central authorities is provided with the ostiolate ring of colluding with backward, two outer side edges of below respectively are provided with button and become attached to, two buttons are become attached to and are then detained two inner side edges that knot is fixed in the chain body respectively, it is characterized in that joint head is the metal construction of tool plasticity, the ring body that the place ahead is square, the rear end of this ring body is installed with The clamp of type,

Ask every being provided with some sawtooth with the form that staggers relatively the both sides, inside of this clamp, one end of this pulling-on piece is inserted in the clamp of joint head rear end, the sawtooth of this clamp inside is fixed the pulling-on piece firm grip, the ring body in this joint head the place ahead place collude with serobila collude with the ring on; This pulling-on piece is included in the transparent surrounding layer that the combined outside of colored interior lamellar body has reflecting strips and outer peripheral edges thereof to coat.

Major advantage of the present utility model is that to have a joint head sturdy and durable, and pulling is difficult for deforming and improving the effect in service life easily.

Further specify below in conjunction with preferred embodiment and accompanying drawing.

Fig. 2 is the combination schematic diagram of slide fastener commonly used;

Fig. 3 is the user mode schematic diagram of slide fastener commonly used;

Fig. 4 is a decomposing schematic representation of the present utility model;

Fig. 5 is a combination schematic diagram of the present utility model:

Fig. 6 is a user mode schematic diagram of the present utility model.

Consult Fig. 4-Fig. 6, the utility model comprises chain body 10, serobila 20 and pulling-on piece 60, the upper surface of its serobila 20 the place ahead central authorities is provided with backward ostiolately colludes with encircling 21, two outer side edges of below respectively are provided with button and become attached to 22, two buttons are become attached to 22 and are detained two inner side edges that knot is fixed in chain body 10 respectively, it is characterized in that joint head 50 is the metal construction of tool plasticity, the ring body 51 that the place ahead is square, the rear end of this ring body 51 is installed with

The clamp 52 of type, the both sides, inside of this clamp 52 are interval with some sawtooth 53 with the form that staggers relatively, this pulling-on piece 60 is included in the transparent surrounding layer that the combined outside of colored interior lamellar body 61 has reflecting strips 62 and outer peripheral edges thereof to coat, during combination, one end of this pulling-on piece 60 is inserted in the clamp 52 of joint head 50 rear ends, the sawtooth 53 of these clamp 52 inside is fixed pulling-on piece 60 firm grip, the ring body 51 in these joint head 50 the place aheads place collude with serobila 20 collude with encircling on 21, finish combination.Because the clamping contact area that joint head 50 and pulling-on piece are 60 is bigger, can make the point of application be evenly distributed in joint head 50, makes joint head 50 sturdy and durable, be difficult for producing distortion, improve service life; The winding of the clamp 52 clamping pulling-on pieces 60 of joint head 50 is simple and easy, convenient, rapid; This pulling-on piece 60 is provided with reflecting strips 62, improves the decorative effect and the security at night.
