Specific embodiment
To make the purpose of this utility model, content and advantage clearer, with reference to the accompanying drawings and examples, to this practicality
New specific embodiment is described in further detail.
As Fig. 1 to Fig. 6 be show a kind of Novel universal sleeve, illustrate each component structure and between each other
Matching relationship.
The sleeve includes an internal mandrel, and the mandrel upper end sets external screw thread 3, and lower end is circumferentially provided with six and is evenly distributed with
Slide block slot 1, the radially movable sliding block 7 of circumference uniform distribution six coordinated with slide block slot 1,7 lower portion of sliding block band taper, every
The inside of a sliding block 7 is there are one hole, with screw assembling there are one six side's mandrels 5 among internal mandrel, under six side's mandrels 5
There are six portions, and uniformly distributed hole is corresponding with the hole on sliding block 7, whole equipped with spring 9 in the hole opposite with six side's mandrels 5 of sliding block 7
It is the housing with annular knurl outside a sleeve, the lower end inside of housing and the cone match of sliding block, enclosure interior are matched somebody with somebody by screw thread
Conjunction can be moved up and down along mandrel, radially scaling be realized by moving up and down for housing come band movable slider, to adapt to different-diameter
Outer six sides screw.
The outer housing also plays sliding block fixation, ensures to slide in addition to it can realize with movable slider and radially scale
Correct position of the block in mandrel is without coming off.
The elastic force of the spring is moderate, ensures sliding block energy natural extension when unclamping, and will not to compare when reducing
Arduously, and spring force will be enough by six sliding block supports to range.
As shown in Figure 1, for internal mandrel, six of which slide block slot 1 is evenly distributed in internal mandrel, internal mandrel upper end
Dynamic interface 2, for the use of various power sources, there is external screw thread 3 in internal mandrel upper end.
As shown in Fig. 2, being assembled together for six side's mandrels 5 by screw 4 with internal mandrel, lower part is six placement springs
The first hole 6, it is corresponding with the second hole 8 on sliding block 7.
As shown in figure 3, clearance fit between sliding block 7 and slide block slot 1, sliding block 7 can be radially movable in slide block slot 1,
It can realize the variation of radial dimension.
As shown in figure 4, spring 9 be positioned in the second hole 8 corresponding on the first hole 6 and sliding block of six side's mandrels 5 and
Uniformly distributed six.By the elastic force of spring 9 sliding block 7 is made to be put into maximum magnitude naturally in the case of unfettered, facilitate reality
It uses.
As shown in figure 5, for external shell, the inner upper end of external shell has internal thread 10, the external screw thread 3 with mandrel upper end
Cooperation realizes moving up and down for external shell by twisting, and there are annular knurl 12, friction when increase twists in the outside of external shell
Power, the interior lower end of external shell have inner conical surface 11, are fitted close with the male cone (strobilus masculinus) 13 on sliding block 7.
The final installation diagram of Universal sleeves is illustrated in figure 6, practical work process is：In inside external shell
Screw thread 10 and the external screw thread 3 of mandrel upper end coordinate, during diminution, by moving down for external shell, housing inner conical surface 11 with it is sliding
Cooperation between block male cone (strobilus masculinus) 13 drives six sliding blocks 7 to shrink radially inward；During expansion, by external shell to moving up
Dynamic, the cooperation between housing inner conical surface 11 and sliding block male cone (strobilus masculinus) 13, six sliding blocks 7 radially expand under the drive of spring 9
, the arbitrary adjustment of Universal sleeves scope is realized with this.
Practical operation illustrate, when running into the bolt or nut of different-diameter, only need to according to the size of nut, no matter metric system
It is or made in Great Britain, it is only necessary to by adjusting outer housing up and down, to be stepped up nut or bolt with six sliding blocks 8, then in power interface
It connects power source and the elastic of nut or bolt can be realized, within the specific limits, be adapted to the adjustment of any size size, make
With very convenient.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, several improvement and deformation can also be made, these change
The scope of protection of the utility model is also should be regarded as into deformation.
