Description

Improved Zipper Pull Structure

technical field

The utility model relates to an improved zipper head structure, in particular to an improved zipper head structure which can limit the position of a horse hook, has good structural strength and is simple and easy to assemble.

Background technique

Most existing zipper puller structures include a slider, a hook, a shrapnel, a cap, and a pull piece. The hook is pushed into the guide groove of the slider by the shrapnel. The cap is fixed on the slider and placed above the hook and the shrapnel. No. M292296 promptly discloses a kind of " zipper slider combination structure (2) " as TW patent certificate No. M292296.

However, in the structure of the existing zipper puller, the hook is pressed against and inserted into the chute of the slider by the shrapnel. Since the hook is only fixed by the elastic force provided by the shrapnel, when the pulling force of the pull piece is too large, the fulcrum of the hook will That is, excessive displacement may occur, causing the hook to deform or fall out of its intended position.

Contents of the invention

The main purpose of the utility model is to overcome the deficiencies and defects of the prior art, and propose an improved zipper head structure, which can provide the function of the fulcrum of the horse hook to stop and limit. Excessive displacement of the fulcrum will not occur, and there will be no defects that cause the hook to deform or fall out of the intended position.

In order to achieve the above object, the utility model provides an improved structure of the slider of the zipper, comprising: a slider with a guide groove formed inside; the top of the slider has an accommodating portion and a perforation, and the perforation penetrates into the guide groove ; a horse hook, which has a hook portion and a fulcrum, the top surface of the horse hook forms a conflicting surface, and the horse hook is accommodated in the accommodating portion of the slider; a pull piece, one end of which has an end portion, the end The part is placed under the hook; an elastic piece, one end of which is fixed on the slider, and the elastic piece is in contact with the contact surface of the hook, so that the hook part of the hook passes through the hole of the slider and extends into the slider. inside the guide groove; and a cap, with a protrusion on both sides of the interior, the cap is placed above the hook and the shrapnel, the cap is fixed on the slider, and the two protrusions of the cap are The part is above the fulcrum of the horse hook.

The utility model has the following beneficial effects: In addition to being fixed by the elastic force provided by the shrapnel, the horse hook of the utility model is provided with two convex parts above the fulcrum of the horse hook, which can provide the function of stopping and limiting. When the pulling force of the pull tab is too large, the fulcrum of the hook will not be displaced excessively, and there is no danger of causing the hook to deform or leave the predetermined position. Furthermore, the two protrusions are integrally formed on both sides of the inside of the cap, which has good structural strength and simple and easy assembly, which can effectively reduce the cost.

In order to enable a further understanding of the features and technical content of the present utility model, please refer to the following detailed description and accompanying drawings of the present utility model. However, the attached drawings are only for reference and description, and are not intended to limit the present utility model. .

Detailed ways

Please refer to Fig. 1 to Fig. 4, the utility model provides a kind of improved zipper puller structure, comprises a puller 1, a horse hook 2, a shrapnel 3, a cap 4 and a pull piece 5, the inside of the puller 1 A guide groove 11 is formed for cooperation with a slide fastener (not shown). The top of the slider 1 has an accommodating portion 12 that can fit the horse hook 2 . Two sides of the accommodating portion 12 are provided with protruding stop portions 13 , two ends of the accommodating portion 12 are respectively provided with a through hole 14 and a platform 15 , and the through hole 14 penetrates through the guide groove 11 . One end of the top of the slider 1 is provided with a fixing seat 16 .

A hook portion 21 is formed at one end of the hook 2 , a fulcrum 22 is formed at the other end of the hook 2 , and a contact surface 23 is formed on the top surface of the hook 2 . The hook 2 is accommodated in the accommodating portion 12 of the slider 1 , and the stop portion 13 is stopped on both sides of the hook 2 to prevent the hook 2 from shifting left and right. The hook portion 21 of the horse hook 2 fits in the through hole 14 , and the fulcrum 22 of the horse hook 2 is carried on the platform 15 . One end of the pull tab 5 has an end portion 51 , and the end portion 51 is placed below the middle of the horse hook 2 .

The shrapnel 3 is made of a metal material with better elasticity, and it is in the shape of a sheet. One end of the shrapnel 3 is fixed on the fixing seat 16 of the slider 1, and the other end of the shrapnel 3 forms a free end and interferes with the slider. The contact surface 23 of the hook 2, so that the hook portion 21 of the horse hook 2 can pass through the perforation 14 of the slider 1 and extend into the inside of the guide groove 11, so as to be caught on the chain teeth of the zipper, and the slider can also be pulled. The sheet 5 separates the hook portion 21 of the horse hook 2 from the fastener teeth of the slide fastener.

The cap 4 is a hollow cover with an open bottom. A notch 41 is formed on both sides of the cap 4 (see FIG. 4 and FIG. 5 ), and the end 51 of the pull tab 5 passes through the two notches 41 . A protruding portion 42 protrudes from both sides of the cap 4 , and each protruding portion 42 has a limiting surface 421 at its lower end. The cap 4 is placed on the top of the slider 1, and the cap 4 is placed on the top of the hook 2 and the shrapnel 3 at the same time. The two sides of the cap 4 are riveted and fixed on the slider 1 at four points. The hook 2 and the shrapnel 3 etc. are combined into a zipper head structure, and the limiting surfaces 421 of the two convex parts 42 of the cap 4 are located above the fulcrum 22 of the horse hook 2, so that the limiting surfaces 421 of the two convex parts 42 can be used to provide the slider. The position-limiting effect of the fulcrum 22 of the hook 2 forms the improved slider structure of the utility model through the above-mentioned composition.

In addition to being fixed by the elastic force provided by the shrapnel 3, the horse hook 2 of the present utility model is provided with two convex parts 42 above the fulcrum 22 of the horse hook 2, which can provide the function of stopping and limiting, so when the pull piece 5 When the pulling force is too large, the fulcrum 22 of the horse hook 2 will not be displaced excessively, and there is no risk of causing the horse hook 2 to deform or leave the predetermined position.

Furthermore, the two protrusions 42 are integrally formed on both sides of the cap 4 , with good structural strength and simple and easy assembly, which can effectively reduce the cost.
