Description

Clip for sleeve device (five)

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. 8, the Clip for sleeve device of the previous application of this creator, 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 Fig. 9, the another Clip for sleeve device of this creator design, it is for the program in the case assembling before improving and is more smooth when making nut withdraw from sleeve, and interior concave ring groove 222 is opened in the bottom of fit end, so the existing bottom 243 semicircle arcuations of elastica body 24 can with interior concave ring groove 222 fit clips, except the moulding at case clip edge break angle before can saving, because when interior concave ring groove 222 is located at fit bottom portion and also can be prevented that nut from taking out, end face is replaced interior concave ring groove 222, and then obtains bigger benefit in the use.

Above-mentioned two previous application cases, it prevents that the elastica body from skidding off the mode of sleeve, all be in sleeve, to offer interior concave ring groove, fit is spacing with it and with the knuckle of elastica body or bottom semicircular arcuation, because interior concave ring groove is to form with car system, yet in the processing of the sleeve of path, process tool promptly can't stretch into the processing operation of the car system of doing in the sleeve, form the blind spot of path sleeve processing, thereby reduce intrinsic utilization benefit.

In view of this, this creator satisfies with its working experience for many years, through continuous research and design, finally grind and create the next spacing elastomer of a kind of mode of utilizing punching press to be forced into, and then save offer in the puzzlement of concave ring groove, and the effect that has the clip nut equally, this is design aim of the present utility model.

Be that main purpose of the present utility model provides the mode that a kind of utilization is forced into elastomer is positioned in the sleeve, reach and prevent the purpose that comes off, and and then simplify procedure and promote the Clip for sleeve device of assembling convenience.

For this reason, the utility model mainly is to offer groove in the fit end internal face of sleeve, other has an 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 is to be slightly larger than the sleeve hexagon ring, and the clip limit is that bending forming protrudes out flange in addition; 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, can make the elastomer lug be anchored in the sleeve and can not come off with the kenel of ratchet skids off, elastomeric clip limit then places the groove position of sleeve lining face in addition, and make its flange protrude from internal face, and then provide the effect of clip clamping nut.

The utility model can also following manner be implemented: the lug of this elastomer packing ring is to be convexly set in knuckle place and clip in the inverted arc angle of sleeve;

This elastomeric packing ring is hexagonal ring-type, circular or polygonal ring-type;

This elastomer only is convexly equipped with single clip limit in side extension;

This elastomer is the Semicircular packing ring of moulding only, and extends and to be convexly equipped with the clip limit, has spacing effect after being forced into sleeve equally.

Because the utility model is the mode that adopts punching press to be forced into elastomer is limited in the sleeve, therefore concave ring groove came the ammunition feed gonosome spacing in sleeve itself promptly needn't be offered separately again, and can overcome the processing blind spot of concave ring groove in the path sleeve car system fully, thereby significantly improve the scope of application and reduce procedure.

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

See also Fig. 1,2, the utility model is that two corresponding sides inwalls in sleeve 20 fit ends 22 offer groove 221 respectively, one elastomer 30 is punching bending formings, its bottom is one to be smaller than the ring-type packing ring 301 of sleeve 20 hexagon rings, 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 being convexly equipped 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 sleeve 20 along groove 221, after packing ring 301 was forced into sleeve 20, it can avoid the centre bore 23 of sleeve, and can firmly be limited in the sleeve 20, and replace originally must offer in concave ring groove so that the clip mode that comes off of preventing to be provided, except eliminating the processing blind spot, also can simplify procedure, and have the spacing effect that comes off of preventing equally.See also Fig. 3, 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 and to grip nut 25, make it be difficult in sleeve, coming off.See also Fig. 4, because elastomer 30 is to be positioned in the sleeve 20 in the mode that is forced into, when therefore breaking away from the clip limit 302 of elastomer 30 when nut 25 taking-ups, this elastomer 30 will still can firmly be limited in the sleeve 20.See also Fig. 5, the utility model is to offer groove 221 at sleeve fit end 22 walls, corresponding elastomer 30 is the single clip of moulding limit 302 only, and the lug 304 of its packing ring also can be convexly set in the knuckle place, after packing ring 301 is forced into fit end 22, but 304 proper clips of lug are positioned to have the effect of clip and location equally in the inverted arc angle 223 of sleeve under the fit that does not influence sleeve and nut.See also Fig. 6, the packing ring 301 of the utility model elastomer 30 also may be molded to semicircle shape, and is convexly equipped with clip limit 302 by the two ends extension, and the packing ring 301 of semicircle shape equally also can reach the purpose that is limited in the sleeve 20.See also Fig. 7, the packing ring 301 of the utility model elastomer 30, it also can be only extends in single end be convexly equipped with clip limit 302, and in the time of in packing ring 301 is anchored on sleeve 20, single clip limit 302 is enough clip clamping nuts also.

In sum, case was in the processing blind spot of path sleeve before the utility model can effectively improve really, and clip clamping nut effect can be provided equally and reach and prevent that the elastomer disengaging from skidding off sleeve, and significantly improve its utilization benefit, and not seeing has identical product public offering to use and be seen in publication, so propose utility application in accordance with the law.
