The dry material of the separated dehydration of liquid of matter and various concentration and containing solid particle, fiber, the liquid of suspension and liquid,
Gas, the mixture of solid.Universal joint is the important component part of screw pump, and the using effect of universal joint and life-span are to screw pump
Quality have conclusive impact.
As it is shown in figure 1, at present, the button universal joint on market and is turned connecting rod 1, button universal joint 2 by straight pin 4
Moving axis 3 links together, and is tied with elastic spring 5 outside straight pin 4 and is fixed.In actual use, steel wire gear
If circle 5 winding tension, then installing/dismounting is the most difficult；If elastic spring 5 is wrapped over pine, elastic spring 5 easily comes off, and rises
Less than the effect of fixed cylinder pin 4, straight pin 4 also can fall off phenomenon, affects the connection of each parts of button universal joint.With
Time, the outside not parcel of this button universal joint straight pin 4, external agency is easily accessible inside straight pin 4 and button universal joint, shadow
Ring the service life of button universal joint.
Utility model content
For the problem in the presence of prior art, a kind of pin interstage sleeve formula button universal joint that this utility model provides,
Straight pin can be blocked, it is to avoid straight pin comes off by pin interstage sleeve；Meanwhile, pin interstage sleeve it also avoid external agency and enters circle
Inside pin and button universal joint；This utility model convenient disassembly, is also effectively improved service life.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of pin interstage sleeve formula button universal joint, including connecting rod, button universal joint and rotary shaft, described connecting rod and institute
Stating button universal joint to connect, described button universal joint is connected with described rotary shaft, and described connecting rod is with described button universal joint even
The place of connecing and described button universal joint are equipped with straight pin with described rotary shaft junction and are fastened, and set outside described straight pin
There is the pin interstage sleeve of annular.Pin interstage sleeve is used for blocking straight pin, prevents straight pin from coming off, and meanwhile, pin interstage sleeve is also used for resistance
Gear external agency enters inside straight pin and button universal joint.
Preferably, the length of described straight pin is identical with the diameter length of described connecting rod and described rotary shaft respectively.Circle
What pin can mate respectively is inserted in connecting rod and rotary shaft, conveniently adds Wrap device again in the outside of straight pin.
Preferably, described connecting rod and described rotary shaft are equipped with the gear edge of fixing described pin interstage sleeve.Gear is along being used for
Fixator pins interstage sleeve.
Preferably, described connecting rod and described rotary shaft are all provided only with gear edge described in side, described gear edge and described pin
Sub-interstage sleeve is fitted, and the opposite side of described pin interstage sleeve is provided with elastic spring and is fixed.The both sides of pin interstage sleeve respectively keep off edge
And elastic spring, pin interstage sleeve is blocked.
Preferably, described connecting rod and described rotary shaft are equipped with the fixing groove of fixing described elastic spring.Fixing groove
For preventing elastic spring from sliding.
The beneficial effects of the utility model show:
1, this utility model can be by straight pin being stuck in annular groove tightly by pin interstage sleeve, it is to avoid cylinder occurs
The phenomenon that pin comes off, thus improve the stability connected between each parts of this utility model, and convenient disassembly.
2, pin interstage sleeve of the present utility model can enter inside straight pin and button universal joint by block media effectively, keeps away
Exempt from external agency and of the present utility model use has been produced impact, improve service life of the present utility model.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of existing a kind of button universal joint；
Fig. 2 is the overall structure schematic diagram of this utility model a kind of pin interstage sleeve formula button universal joint；
In figure: 1-connecting rod, 2-button universal joint, 3-rotary shaft, 4-straight pin, 5-elastic spring, 6-pin interstage sleeve.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described for the ease of it will be appreciated by those skilled in the art that.
Fig. 2 is overall structure schematic diagram of the present utility model, including connecting rod 1, button universal joint 2 and rotary shaft 3, connects
Bar 1 is all connected with rotary shaft 3 with button universal joint 2 and button universal joint 2 under the fastening of straight pin 4, and straight pin 4 is outside to be set
Having the pin interstage sleeve 6 of annular, pin interstage sleeve 6 one end is adjacent to keep off edge, and one end of pin interstage sleeve 6 is fixed by elastic spring 5.
Detailed description of the invention of the present utility model is as follows:
As in figure 2 it is shown, connecting rod 1 and button universal joint 2 and button universal joint 2 with rotary shaft 3 equal tight at straight pin 4
Gu achieving the function of universal joint under, pin interstage sleeve 6 is used for preventing straight pin 4 from coming off, and stops that external agency enters straight pin 4
