Abstract

The utility model discloses a clamp for sleeve barrels. The utility model is characterized in that the inner wall of two corresponding sides of the sheathing end of a sleeve barrel are respectively provided with a groove, and the bottom of the sheathing end is provided with an inward concave ring groove; a clamping side is convexly provided with a flange and an elastic thread body whose bottom is in the shape of a half circular arc. The clamping side can be put into the sleeve barrel along the groove of the sheathing end when the utility model is assembled, and the half circular arc-shaped bottom of the elastic thread body is clamped in the inward concave ring groove of the bottom of the sheathing end. Thereby, the half circular arc-shaped bottom of the elastic thread body is directly clamped in the inward concave ring groove of the sleeve barrel to prevent the fall of the elastic thread body, can be conveniently forcibly assembled and simplifies the processing program of the elastic thread body, and thus, the production benefit of the utility model is greatly increased.

Description

The Clip for sleeve device

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 shown in Fig. 1,2, it is the Clip for sleeve device of the previous exploitation of this creator, it mainly is to make square endoporus in the pivot end 21 of

sleeve

20,22 at the fit end of the other end is hexagonal endoporus, at 22 at pivot end 21 and fit end, for having the interlude of centre bore 23, the two-phase corresponding sides inwall of fit end 22 wherein, offer groove 221 respectively, in offer concave ring groove 222 near end position, one elastica body, 24 one side clip limits 241 convex with

flange

242, and 243 of bottoms are the semicircle arcuation, and end 244 then bending is a knuckle; In when assembling because of elastica body 24 for having plasticity, therefore clip limit 241 can be forced in the sleeve 20 along fit end groove 221, in the end 244 that is forced into back elastica body 24, then just can replace in the interior concave ring groove 222 that is limited in fit end 22, bottom 243 is the semicircle arcuation, then can avoid the centre bore 23 of sleeve 20, and pass through along its outer shroud wall; The flange 242 that is convexly equipped with of clip limit 241 by this, when nut 25 is inserted in sleeve 20 fit ends 22, its elasticity tension can be pressed folder positioning screw cap 25, make it be difficult in sleeve 20, coming off, and interior concave ring groove 222 is replaced in the end 244 of elastica body 24, and therefore when nut 25 took out, elastica body 24 is not slippage thereupon also, and can provide bolt to penetrate, and make the fit end finish the effect of fit nut.

Aforesaid product is on making and using, all can permit symbol its intended purposes and effect, only because of its elastica body when assembling with sleeve, essential in advance at its both ends 244 bending formings, one knuckle, make and replace spacing with the interior concave ring groove 222 of sleeve 20, prevent that it from coming off in sleeve 20, when this mode is assembled in groove 221 in clip limit 241 correspondences, because of its end 244 has knuckle, therefore when being forced into elastica body 24, be difficult for the operation assembling, and can't improve packaging efficiency.In addition, as shown in Figure 2, because interior concave ring groove 222 is to be opened near end position, therefore, if when nut 25 is sleeved on the inner position of sleeve 20, sleeve 20 is more goed deep in the position of promptly interior concave ring groove 222, then when nut 25 is desired to withdraw from sleeve 20,, and make wherein one inclination is arranged slightly if nut 25 does not keep levelness with sleeve 20, then will make the end face that withdraws from of nut 25 push up interior concave ring groove 222, and cause withdraw from not smooth.

In view of this, this creator satisfies with its working experience for many years, through continuous research and design, grind and create utilization the interior concave ring groove of clip elastica body knuckle is opened in fit bottom portion, make itself and the existing mutual clip in the bottom that is the semicircle arcuation of elastica body, and omit the knuckle moulding, and then simplify processing procedure and increase the assembling convenience, and making nut smooth moving in sleeve, this is design aim of the present utility model.

Main purpose of the present utility model is to be to provide a kind of more practical and simplify processing procedure and assembling Clip for sleeve device more easily.

For this reason, it mainly is to offer concave ring groove in the fit bottom of this sleeve portion for the utility model, utilize the existing bottom semicircular arcuation clip of elastica body in wherein, clip by interior concave ring groove and elastica body bottom, can reach the elastica body and firmly be limited in the interior purpose of sleeve fit end, and replace previous clip mode with end, clip limit knuckle.

Clearly, because the end, clip limit of elastica body need not mold knuckle, so can reduce procedure, and after end, clip limit omitted knuckle, can make the clip limit when assembling is forced into, insert the groove of sleeve in mode more easily, and have the convenience of fit on, and interior concave ring groove is opened in fit bottom portion, can avoid nut when withdrawing from, it withdraws from end face and replaces interior concave ring groove, and guarantees that nut moves in sleeve smoothly.

In sum, the utility model utilizes the existing semicircle arcuation of elastica body, directly with sleeve in interior concave ring groove clip prevent from the design that comes off from can make its procedure for processing simplify and increase and assembling convenience.

For making the utility model is had further understanding, exemplify a preferred embodiment now, and conjunction with figs. describes in detail as the back:

Fig. 1: the parts explosion that is prior art;

Fig. 2: the generalized section that is prior art;

Fig. 3: be parts explosion of the present utility model;

Fig. 4: be generalized section of the present utility model;

Fig. 5: be enforcement illustration of the present utility model ();

Fig. 6: be enforcement illustration of the present utility model (two).

See also Fig. 3, shown in 4, the utility model is that the two-phase corresponding sides inwall in sleeve 20 fit ends 22 offers groove 221 respectively, bottom position in the fit end offers concave ring groove 222 in addition, the clip limit 241 of elastica body 24 convexes with flange 242,243 of bottoms are the semicircle arcuation, in when assembling because of elastica body 24 for having plasticity, therefore the groove 221 of clip limit 241 along fit end 22 can be forced in the sleeve 20, and by elastica body 24 with existing semicircle arcuation bottom 243 and interior concave ring groove 222 fit clips, and replace original knuckle clip mode, not only can save the procedure of elastica body 24 knuckles, and after knuckle has been lacked on the clip limit 241 of elastica body 24, can be forced into the groove 221 of sleeve more easily, make that assembling is more convenient;

See also Fig. 5, when nut 25 clips in sleeve 20 fit ends 22, and by the flange 242 on elastica body 24 clip limits 241, and compress binding nut 25 with its elasticity tension, make it be difficult in sleeve 20, coming off; See also Fig. 6, because elastica body 24 bottoms 243 are the semicircle arcuation, and clip is in interior concave ring groove 222, therefore, when nut 25 breaks away from the clip limit 241 of elastica body 24, and when sleeve 20 fit ends 22 take out, these elastica body 24 bottoms 243 because of with the result of interior concave ring groove 222 clips, make being limited in the sleeve 20 fit ends 22 that elastica 24 also can be firm, and have the spacing effect of clip, and the end face that withdraws from of nut 25 also will interior concave ring groove 222 more protrudes opening near sleeve 20, so it is when withdrawing from, end face will can not be replaced interior concave ring groove 222, and can guarantee to move smooth.

In sum, the utility model can effectively be pressed the folder nut really, and the elastica body also can be firm be limited in the sleeve fit end, centre bore also can provide original effect, and dark tool practicality and progressive, so do not see to have identical product public use or open, so propose utility application in accordance with the law in publication.
