Description

The slider of zipper fastener structure

Technical field

The utility model relates to a kind of slider of zipper fastener structure, refers to a kind of slider of zipper fastener structure that can the horse hook of slider of zipper fastener is spacing especially.

Background technology

Press, but slider of zipper fastener is the coupling member as folding that because it has the characteristic of simple operation, so even to this day, slider of zipper fastener significantly is used for suitcase and ready-made clothes.The principle of slide fastener is to be: but borrow the zipper strip of subtend engagement, and the reciprocal pulling by slider of zipper fastener is with as folding, and the material of zipper strip and slider of zipper fastener can be metal, nylon or plastic-steel etc.

Known slider of zipper fastener roughly includes a pull head, a horse hook, a shell fragment, a cap and a pulling-on piece, the horse hook is to borrow compressing of shell fragment and stretch in the guide groove that pull head is provided with, and an end of pulling-on piece is positioned at horse hook below, cap then covers being fixed on the pull head of putting, and makes horse hook and shell fragment be positioned at cap inside; For example: Taiwan TWM292296 number (application number: 95200113) novel patent case is promptly exposed a kind of " slider of zipper fastener combining structure (two) ".

But, known slider of zipper fastener, its horse hook is to compress and be inserted in the guide groove of pull head with shell fragment, the elastic force that yet the horse hook only utilizes shell fragment to be provided is fixed, when the pulling force of pulling-on piece is excessive, then excessive displacement promptly might take place in the fulcrum that had of horse hook, causes the distortion of horse hook or breaks away from original default position.

Therefore, the improving of the above-mentioned defective of designer's thoughts of the present utility model is that the spy concentrates on studies and cooperates the utilization of scientific principle, proposes a kind of reasonable in design and effectively improve the utility model of above-mentioned defective finally.

The utility model content

The purpose of this utility model provides the slider of zipper fastener structure that a kind of fulcrum that can make the horse hook has the block limit function and over-travel can not take place and cause the distortion of horse hook or break away from the precalculated position.

To achieve the above object, the utility model provides a kind of slider of zipper fastener structure, comprising: a pull head, and its inside is formed with guide groove, and the top that this pull head has is provided with a perforation and a locating hole, and this perforation is through to this guide groove; One horse hook, it is arranged on the top of this pull head, this horse hitcher has a base portion, to bend the fulcrum of extension from the hook part and that this base portion one end bends extension downwards downwards from this base portion other end, and the perforation of this pull head is stretched in the hook part of this horse hook, and this fulcrum stretches into this locating hole; One pulling-on piece, one end have end, a location, and this end, location is arranged at the place, below of this horse hook; One shell fragment, it has relative first end and the second end, and this first end is fixed on this pull head, and this second end elasticity contacts at the base portion of this horse hook; And a cap, its lid places on the top of this pull head, and this horse hook and this shell fragment are placed in this cap, and the internal face that forms this cap inside is equipped with two protuberances, and this two protuberances correspondence is positioned at the top of the fulcrum of this horse hook.

The profitable fruit that the utlity model has: the horse hook is except the elastic force that utilizes shell fragment to provide is fixed, more in cap, form two protuberances, so that its correspondence is positioned at the fulcrum top of horse hook, and then provide block spacing function, therefore, when the pulling force of pulling-on piece was excessive, excessive displacement can not take place in the fulcrum of horse hook, with the anxiety of avoiding causing the distortion of horse hook or breaking away from the precalculated position.

In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet appended accompanying drawing only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.

The specific embodiment

See also Fig. 1 to shown in Figure 5, the utility model provides a kind of slider of zipper fastener structure, and it comprises a pull head 1, a horse hook 2, a pulling-on piece 3, a shell fragment 4 and a cap 5.

The inside of pull head 1 is formed with guide groove 11, cooperates with zipper strip (not shown) so as to supplying.The top that pull head 1 has is provided with a perforation 12 and one locating hole 13, and perforation 12 is through to guide groove 11.In addition, perforation 12 both sides are equipped with the stop section 14 that is formed by pull head 1 respectively, and the end at the top of pull head 1 and be provided with an outstanding holder 15.

Horse hook 2 has one and is straight base portion 21, a hook part 22 and a fulcrum 23, and hook part 22 bends and extends into type downwards from an end of

base portion

21, and 23 other ends from base portion 21 of fulcrum bend and extend into type downwards.

Pulling-on piece 3 one ends have end 31, a location.

Shell fragment 4 is made with the flexible metal material of tool, and it is a demihull shape, and shell fragment 4 has relative first end 41 and the second end 42.

Cap 5 is the lid that a bottom is the inner recess shape, and cap 5 relative both sides respectively are provided with a breach 51, and the end that the internal face of formation cap 5 inside is equipped with two protuberances, 52, two protuberances 52 respectively has a confined planes 521 (as Fig. 5).

By above-mentioned, the end, location 31 of pulling-on piece 3 is arranged at the over top of pull head 1 earlier, 2 on horse hook is arranged on the top of pull head 1, make the end, location 31 of pulling-on piece 3 be positioned at the place, belows of horse hook 2 centres, and the hook part 22 of horse hook 2 is inserted in the perforation 12 of pull head 1, and 23 of fulcrum stretch in the locating hole 13 of pull head 1.

Shell fragment 4 is arranged on the top of pull head 1, and the first end 41 of shell fragment 4 is fixed on the pull head 1, and the second end 42 elasticity contact on base portion 21 surfaces of horse hook 2, make the hook part 22 of horse hook 2 can stretch in the perforation 12 of pull head 1; In the utility model specific embodiment, the first end 41 of shell fragment 4 is fixedly arranged on the holder 15 of pull head 1, and stop section 14 blocks of pull head 1 produce left and right displacement in horse hook 2 both sides in order to prevent horse hook 2.
