Description
Technical field
The utility model relates to transmission art field, particularly relates to a kind of universal joint.
Background technique
In prior art, the cardan shaft that tradition uses has cross-axle universal shaft axle, and it is made up of two transmitting assembliess and a cross axle, but, the shortcomings such as the cardan shaft of Cardon universal joint is little because the application of cross axle makes universal joint have application angle of operation, and work not steadily and the life-span is short.
Please refer to Authorization Notice No. CN 203726700 U again, the patent documentation of application number 201420016990.3, connection joint described in this patent documentation is universal joint, it comprises adapter sleeve and connecting joint, and this connecting joint one end is hemisphere structure and realizes movable connection by this structure and adapter sleeve, thus, this connection joint is made to have good stable working, but it is little that this connection joint but still has angle of operation, the defect that the life-span is low.
Summary of the invention
The utility model provides a kind of angle of operation good Universal joint in larger and working life for overcoming above-mentioned defect.
For achieving the above object, the utility model adopts following technological scheme.
A kind of universal joint, comprise mobilizable connecting joint and adapter sleeve, described connecting joint comprises grip slipper and is rotatably installed in the driving piece of described grip slipper, described driving piece and described adapter sleeve pivot joint.
Preferably, described driving piece is in roughly sphere-like.
Preferably, all sides of described driving piece are arranged with four arc pivot connected slots equably.
Preferably, described adapter sleeve one end is the plane of a hollow, and the other end is the arc driving arm of a semicircular in shape.
Preferably, each arc pivot connected slot described is in roughly " U " type.
The beneficial effects of the utility model are: a kind of universal joint of the present utility model, comprise mobilizable connecting joint and adapter sleeve, described connecting joint comprises grip slipper and is rotatably installed in the driving piece of described grip slipper, described driving piece and described adapter sleeve pivot joint.Together with by mobilizable driving piece described connecting joint being articulated in described adapter sleeve, achieving the rotatable function of described universal joint, meanwhile, increase the angle of operation of this universal joint, and then, extend the working life of described universal joint.
Accompanying drawing explanation
With accompanying drawing, the utility model is described in further detail, but the embodiment in accompanying drawing is not formed any restriction of the present utility model.
Fig. 1 is the perspective exploded view of a kind of universal joint of the present utility model.
Fig. 2 is the solid assembling schematic diagram of a kind of universal joint of the present utility model.
Embodiment
Be further described the utility model below in conjunction with drawings and Examples, this is preferred embodiment of the present utility model.
Embodiment.
Please refer to Fig. 1 and Fig. 2, a kind of universal joint 10 of the utility model comprises adapter sleeve 101 and the connecting joint 102 with this adapter sleeve 101 pivot joint.
This connecting joint 102 comprises grip slipper 1021 and is rotatably installed in the driving piece 1022 on this grip slipper 1021.Particularly, this driving piece 1022 is in roughly sphere-like, all sides are arranged with the arc pivot connected slot 10221 (other three arc pivot connected slot figure do not show) that four are roughly " U " type spaced reciprocally, wherein, these four arc pivot connected slots 10221 are relative between two, and the two ends of these four arc pivot connected slots 10221 pool a conocave plane respectively; Further, this driving piece 1022 weeks sides are convexly equipped with the arc pivoted body 10222 (figure does not show entirely) of four strips spaced reciprocally, and the relative between two and two ends of each arc pivoted body 10222 of these four arc pivoted bodies 10222 are in roughly V-type.Certainly, the arc pivot connected slot 10221 of this driving piece 1022 is not limited to four.
This grip slipper 1021 is in roughly spherocylinder shape, and one end is a smooth plane, and the other end is that a square groove running through this grip slipper 1021 is offered, in roughly semicircular driving arm in middle part.Particularly, this driving arm comprises the first driving arm and the second driving arm, and arc pivot connected slot 10221 pivot joint that this first driving arm is relative with this driving piece 1022 liang respectively with this second driving arm.More specifically, the width of this first driving arm and the width of this second driving arm equal the width of this arc pivot connected slot 10221.
This adapter sleeve 101 comprises grip slipper 1011 and arc driving arm 1012.Particularly, this adapter sleeve 101 one end is the plane of a hollow, and the other end is in semi-circular arc driving arm 1012.More specifically, this arc driving arm 1021 comprises the 3rd driving arm 10121 and the 4th driving arm 10122.Wherein, the width of the width of the 3rd driving arm 10121, the width of the 4th driving arm 10122, the width of this arc pivot connected slot 10221 and this square groove is equal.Further, the 3rd driving arm 10121 and the 4th driving arm 10122 another two relative arc pivot connected slot 10221 pivot joints with this driving piece 1022 respectively.
This grip slipper 1011 is in roughly spherocylinder shape, and one end is the plane of a hollow, the other end and this arc driving arm 1012 one-body molded.
During assembling, directly the 3rd driving arm 10121 on the arc driving arm 1012 of adapter sleeve 101 and the 4th driving arm 10122 pivot joint are entered on the two arc pivot connected slots 10221 relatively installed of driving piece 1022, namely complete the assembling of this universal joint 10.
Relatively, during dismounting, the 3rd driving arm 10121 or the 4th driving arm 10122 are rotated to the rectangular recess place of grip slipper 1021, namely during adapter sleeve 101 and connecting joint 102 one-tenth roughly 90 ° of corner structures, the dismounting of this universal joint 10 can be come.
This universal joint 10, by rotatable articulated manner, this universal joint 10 is made to have the function of rotation, in addition, by being installed in the movable driving piece 1022 on this connecting joint 102, this adapter sleeve 101 is rotatably articulated with this connecting joint 102, increases the angle of operation of this universal joint 10, extend the working life of this universal joint 10.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; although done to explain to the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement, and not depart from essence and the scope of technical solutions of the utility model.
