Description

The slider of zipper fastener structure of improvement

Technical field

The utility model relates to a kind of slider of zipper fastener structure of improvement, refer to especially a kind of can the horse hook is spacing, structural strength is good, the simple slider of zipper fastener structure that is easy to improvement of assembling.

Background technology

Existing slider of zipper fastener structure mostly comprises a pull head, a horse hook, a shell fragment, a cap and a pulling-on piece, and the horse hook is to compress in the guide groove that stretches into pull head with shell fragment, and pulling-on piece one end is positioned at horse hook below, and cap is fixed on the pull head, and lid places horse hook and shell fragment top.Number M292296 number i.e. announcement has a kind of " slider of zipper fastener combining structure (two) " as the TW letters patent.

But, existing slider of zipper fastener structure, its horse hook is to compress in the chute that stretches into pull head with shell fragment, because the elastic force that the horse hook only utilizes shell fragment to provide is fixed, therefore when the pulling-on piece pulling force was excessive, excessive displacement promptly might take place in the fulcrum of horse hook, caused the distortion of horse hook or broke away from preposition.

Summary of the invention

Main purpose of the present utility model is to overcome the deficiencies in the prior art and defective, a kind of slider of zipper fastener structure of improvement is proposed, it can provide the spacing function of fulcrum block of horse hook, when the pulling-on piece pulling force is excessive, excessive displacement can not take place in the fulcrum of horse hook, and does not have the defective that causes the distortion of horse hook or break away from the precalculated position.

In order to reach above-mentioned purpose, the utility model provides a kind of slider of zipper fastener structure of improvement, comprising: a pull head, and its inside is formed with guide groove, and this pull head top has a holding part and a perforation, and this perforation is through to this guide groove; One horse hook, it has a hook portion and a fulcrum, and this horse hook end face forms a conflict face, and this horse hook is placed in the holding part of this pull head; One pulling-on piece, the one end has an end, and this end places this place, horse hook below; One shell fragment, one end are fixed on this pull head, and this shell fragment contacts at the conflict face of this horse hook, run through the perforation of this pull head and stretch into this guide groove inside with the hook portion that makes this horse hook; And a cap, its inner two sides respectively are provided with a protuberance, and this cap lid places this horse hook and this shell fragment top, and this cap also is fixed on this pull head, and two protuberances of this cap are positioned at the top of the fulcrum of this horse hook.

The utlity model has following useful effect: horse hook of the present utility model is except the elastic force that utilizes shell fragment to provide is fixed, other is provided with two protuberances in the top of the fulcrum of this horse hook, can provide block spacing function, when the pulling-on piece pulling force is excessive, excessive displacement can not take place in the fulcrum of horse hook, and does not have the anxiety that causes the distortion of horse hook or break away from the precalculated position.Moreover this two protuberance is shaped in inner two sides of cap, and structural strength is good, and assembling is easily simple, can effectively reduce cost.

For enabling 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 graphic only provide with reference to the usefulness of explanation, be not to be used for the utility model is limited.

The specific embodiment

See also Fig. 1 to Fig. 4, the utility model provides a kind of slider of zipper fastener structure of improvement, includes a pull head 1, a horse hook 2, a shell fragment 3, a cap 4 and a pulling-on piece 5, and this pull head 1 inside is formed with guide groove 11, can supply slide fastener (figure slightly) to cooperate.This pull head 1 top has a holding part 12 that can cooperate horse hook 2.These holding part 12 2 sides are provided with outstanding stop section 13, and these holding part 12 2 ends are respectively equipped with a perforation 14 and one platform 15, and this perforation 14 is through to this guide groove 11.This pull head 1 top, one end also is provided with a holder 16.

These horse hook 2 one ends form a hook portion 21, and these horse hook 2 other ends form a fulcrum 22, and these horse hook 2 end faces form a conflict face 23, but this conflict face 23 ammunition feed sheets 3 are conflicted.This horse hook 2 is placed in the holding part 12 of this pull head 1, and described stop section 13 blocks produce left and right displacement in these horse hook 2 two sides in order to prevent horse hook 2.The hook portion 21 of this horse hook 2 is matched with in this perforation 14, and the fulcrum 22 of this horse hook 2 is carried on this platform 15.These pulling-on piece 5 one ends have an end 51, and the below was located in the middle of this end 51 placed this horse hook 2.

This shell fragment 3 is made with the preferable metal material of elasticity, it is a slice shape, these shell fragment 3 one ends are fixed on the holder 16 of this pull head 1, the conflict face 23 that these shell fragment 3 other ends then form free end and contact at this horse hook 2, can run through the perforation 14 of this pull head 1 and be inserted into guide groove 11 inside with the hook portion 21 that makes this horse hook 2, so that on the sprocket of slide fastener, also can spurring this pulling-on piece 5, separates with the sprocket of slide fastener clip with the hook portion 21 that makes this horse hook 2.

This cap 4 is the opening-like hollow lid in a bottom, and these cap 4 two sides respectively are formed with a breach 41 (seeing also Fig. 4 and Fig. 5), and this two breach 41 is run through in the end 51 of pulling-on piece 5.These cap 4 inner two sides respectively are equipped with a protuberance 42, and these protuberance 42 lower ends respectively have a confined planes 421.These cap 4 lids place pull head 1 top, this cap 4 covers simultaneously and places horse hook 2 and shell fragment 3 tops, these 4 of cap 4 two side rivetings are fixed on the pull head 1, pull head 1, horse hook 2 and shell fragment 3 etc. are combined into a slider of zipper fastener structure, the confined planes 421 of two protuberances 42 of this cap 4 is positioned at the top of the fulcrum 22 of horse hook 2, thereby the confined planes 421 that can utilize two protuberances 42 provides the fulcrum 22 of horse hook 2 spacing effect, by above-mentioned composition to form the slider of zipper fastener structure of improvement of the present utility model.

Horse hook 2 of the present utility model is except the elastic force that utilizes shell fragment 3 to provide is fixed, other is provided with two protuberances 42 in the top of the fulcrum 22 of this horse hook 2, can provide block spacing function, therefore when pulling-on piece 5 pulling force are excessive, excessive displacement can not take place in the fulcrum 22 of horse hook 2, and does not have the anxiety that causes 2 distortion of horse hook or break away from the precalculated position.

Moreover this two protuberance 42 is shaped in cap 4 inner two sides, and structural strength is good, and assembling is easily simple, can effectively reduce cost.

The above only is preferred embodiment of the present utility model; non-ly be intended to limit to scope of patent protection of the present utility model; so use the equivalence variation for it of the utility model specification and accompanying drawing content institute such as, all in like manner all be contained in the rights protection scope of the present utility model.
