Description

Clip for sleeve device (seven)

The utility model relates to hand-held tool-sleeve of pulling nut for clamping, refers to a kind of Clip for sleeve device especially.

See also Fig. 9, case Clip for sleeve device before of the present utility model, it mainly is the fit end 22 two-phase corresponding sides inwalls in sleeve 20, offer groove 221 respectively, again in offer concave ring groove 222 near end position, the clip limit 241 of one elastica body 24 convexes with flange 242, and 243 of bottoms are the semicircle arcuation, and end 244 then bending is a knuckle; When assembling, elastica body 24 is inserted in the sleeve 20, and make clip limit 241 be inserted in groove 221, concave ring groove 222 in 244 of its ends are replaced and are limited in, by this, the nut that clip limit flange 242 gets final product in the clip gripper sleeve, and when nut takes out in sleeve, can prevent from that elastica body 24 from coming off to skid off in sleeve 20.See also Figure 10, owing to should preceding case be to offer groove 221 at two-phase corresponding sides inwall, therefore sleeve 20 is in the process that multiple-project forges, the moulding of this groove 221 will be than the integrality of destructible to this body structure of sleeve stock, and may produce breakdown point, see also Figure 11, at present on the market the sleeve 20 of common use, most fillet 223 of all between the adjacent edge of hexagon ring, offering, wherein this fillet 223 can replace the stress concentration point of each adjacent edge intersection of sleeve, and with the larger area mode concentrated problem that eliminates stress, this bull nose 223 also can be utilized the ccontaining distortion ridge in space of fillet when nut destroys distortion, to eliminate breakdown point, and then nut can be inserted in the sleeve smoothly, only this kind sleeve still lacks the device of clip nut at present, and its usefulness to be hoisted is arranged.

In view of this, this creator utilizes the moulding of this existing fillet then and cooperates elastomeric setting, and the clip effect of sleeve is provided, and to promote the sleeve effect, this is design aim of the present utility model.

Be main purpose of the present utility model provide a kind of have clamping clip nut and prevent that elastomer breaks away from skid off the effect of sleeve, and can guarantee the Clip for sleeve device that sleeve forges quality and is easy to assemble.

For this reason, the utility model mainly is that the wall with the sleeve hexagon ring extends back and offers, and the holding part that formation is set up, another elastomer is packing ring and the clip limit that molds ring-type with punching, wherein ring-type packing ring itself is to be slightly less than the sleeve hexagon ring, be convexly equipped with lug in its all side again, and make it be slightly larger than the sleeve hexagon ring, the clip limit is given bending forming to protrude out flange; When elastomer and sleeve assembling, because packing ring is slightly larger than hexagon ring because of lug, therefore after being forced into elastomer in the sleeve in the mode of punching press, elastomer is anchored in the sleeve and can come off and skid off, elastomeric clip limit then places the internal face extension to offer in the holding part of formation in addition, and make its flange protrude from former wall, and then provide the effect of clip clamping nut;

The utility model can also following manner be implemented: each adjacent edge of sleeve fit end hexagon ring is to offer fillet, with dispersive stress and ccontaining nut deformation point;

And the lug of this elastomer packing ring is to be convexly set in the knuckle place, and correspondence is forced into clip in above-mentioned sleeve fillet;

This elastomeric packing ring is hexagonal ring-type, circular or polygonal ring-type, perhaps also can only be shaped to semicircular, and it extends the clip limit that is convexly equipped with and is one or two.

Clearly, the utility model provides to have clamping clip nut and prevents that elastomer breaks away from the effect that skids off sleeve, and because the utility model is former hexagon ring wall to be extended back offer, therefore with regard to the overall structure of hexagon ring, it still still can keep the integrality of hexagonal shape structure, thereby has the advantage that can guarantee that sleeve forges quality and is easy to assemble.

Understand in depth for making the utility model had further, exemplify a preferred embodiment now, and conjunction with figs. explanation as back:

See also Fig. 1, the utility model mainly is to offer fillet 223 between each adjacent edge of sleeve 20 fit ends 22 hexagon rings, effect of concentrating with dispersive stress and the deformation point of taking in nut, and will be wherein a wall 224 extend back and offer, and form a holding part of setting up 225 with former hexagon ring position, owing to offer fillet 223, make the wall thickness of sleeve fit end 22 be fillet 223 to outer rim apart from t ₁, and with wall 224 extend back offer after, its to outer rim apart from t ₂Be still more than or equal to t ₁, so the formation of holding part 225, will can not change the wall thickness intensity and the whole structural strength of original integral body because of the minimizing of wall thickness.See also Fig. 2,3, the utility model is set up holding part 225 at sleeve 20 fit ends, one elastomer 30 is punching bending formings, its bottom is one to be smaller than the ring-type packing ring 301 of sleeve hexagon ring, its all side also convexes with lug 304, packing ring 301 also extends upward the clip limit 302 that bending forming goes out to have flange 303, wherein packing ring 301 is because of convexing with lug 304, and make it be slightly larger than the hexagon ring of sleeve fit end, therefore be to adopt the mode of punching press elastomer 30 to be forced in the sleeve fit end 22 when assembling, and by lug 304 and Clip for sleeve location, and make clip limit 302 insert holding part 225 along wall 224, after packing ring 301 was forced into sleeve 20, it can avoid the centre bore of sleeve, and can firmly be limited in the sleeve 20, prevent the effect that comes off and have the location.See also Fig. 4, when nut 25 clips in sleeve 20 fit ends 22, and replace by the elasticity of the flange 303 on elastomer 30 clip limits 302, grip nut 25, make it be difficult in sleeve, coming off.See also Fig. 5,, therefore be removed and when breaking away from the clip limit 302 of elastomer 30, this elastomer 30 will still can firmly be limited in the sleeve 20 when nut 25 because elastomer 30 is to be positioned in the sleeve 20 in the mode that is forced into.See also Fig. 6, the lug 304 of the packing ring 301 of the utility model elastomer 30 also can be convexly set in the knuckle place, and when being forced into clip, clip is positioned the fillet 223 of sleeve.See also Fig. 7, packing ring 301 of the present utility model also may be molded to circular or polygonal ring-type, and extension is convexly equipped with one or two clip limit 302, the modes that packing ring 301 is forced into punching press equally, be incorporated in the sleeve fit end 22, also can reach the fastening purpose that comes off of preventing.See also Fig. 8, packing ring 301 of the present utility model also can be semicircular, and extension is convexly equipped with two or a clip limit 302.

In sum, the utlity model has clamping clip nut and prevent that elastomer breaks away from the effect that skids off sleeve, more can take into account the integrally-built integrality of sleeve, and not see identical product public offering is arranged or to use and be disclosed on the publication, so propose utility application in accordance with the law.
