Description
Technical field
The utility model is related to one kind prevents shackle dropping device field, and in particular to a kind of to prevent what pivot pin from coming off to unload
Button.
Background technology
When grabbing bucket operation, steel wire rope and rotating prevention sleeve can send out into a degree of rotation and collision, this when of shackle is just
Frictional impact inevitably occurs, unloads the nut buckled and loosens, split pin is too small to come off during impact
So as to cause shackle to come off, there is very big security risk.
The content of the invention
To solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of shackle for preventing pivot pin from coming off,
It effectively can prevent shackle from coming off, improve the security of shackle in use, and then ensure the personal safety of operator.
In order to realize above-mentioned target, the utility model adopts the following technical scheme：
A kind of shackle for preventing that pivot pin from coming off, including：Axis pin, nut, fixing device, split pin, shackle, drilling；It is described
Shackle be U-shaped structure, the axis pin is fixed through the end on two U-shaped sides of shackle and both ends by nut
Connection, and axis pin passes through the nut of one end, and the axis pin is equipped with drilling, and the nut passed through by pivot pin is equipped with
Diameter is more than the through hole of bore diameter, is sequentially inserted into the inside of through hole and drilling with the fixing device, and by nut and pin
Axis is fixed, and the split pin is located at axis pin close to the end of the nut one end passed through by pivot pin, and perpendicular to
The axis direction of axis pin passes through axis pin.
Further, fixing device is countersunk head hexagon socket head cap screw.
Further, the height of the drilling on axis pin is equal to the radius of axis pin.
Further, fixing device and through hole and drilling are clearance fit.
Further, split pin passes through the axis of axis pin.
Further, the junction of nut and axis pin is equipped with packing ring, and the diameter of the packing ring is more than the diameter of axis pin.
Further, the outer surface of shackle is equipped with one layer of anti-skid sleeve, and the anti-skid sleeve is rubber antiskid sleeve.
Further, axis pin and shackle are axis pin and shackle made of stainless steel or hard alloy.
Further, nut is a kind of round nut.
The utility model is beneficial in that：
1）The utility model passes through the design to fixing device so that the connection between bolt and axis pin more fastens, and prevents
Only loosen.
2）By the design to anti-skid sleeve, the frictional force on shackle surface is increased, plays effective antiskid effect.
Brief description of the drawings
Fig. 1 is the structure diagram of the prior art；
Fig. 2 is the structure diagram of the utility model；
Fig. 3 is the enlarged diagram at the utility model a；
The implication of reference numeral in figure：
1 it is axis pin, 2 be nut, 3 be fixing device, 4 be split pin, 5 be shackle, 6 is drilling.
Embodiment
The utility model is further described and illustrated with reference to embodiment and attached drawing, but is not limited in any form
The system present invention.
Embodiment 1
A kind of shackle for preventing that pivot pin from coming off, as shown in Figures 2 and 3, including：Axis pin 1, nut 2, fixing device 3, opening
Pin 4, shackle 5, drilling 6；Wherein, fixing device 3 is countersunk head hexagon socket head cap screw, countersunk head hexagon socket head cap screw mainly have easy to fastening and
Dismounting, it is not easy to which the advantage such as sliding angle, can effectively ensure that the stability of connection, the shackle 5 is U-shaped structure, moreover, unloading
The outer surface of button 5 is equipped with one layer of anti-skid sleeve, this anti-skid sleeve is rubber antiskid sleeve, ensures the antiskid effect of shackle 5 with this.
The axis pin 1 is fixedly connected through the end on two U-shaped sides of shackle 5 and both ends by nut 2, and axis pin
1 passes through the nut 2 of one end, and the axis pin 1 is equipped with drilling 6, and the nut 2 passed through by pivot pin is more than equipped with diameter
Drill the through holes of 6 diameters, with the fixing device 3 be sequentially inserted into through hole and drill 6 inside, and by nut 2 and axis pin 1 into
Row is fixed, and the split pin 4 is located at axis pin 1 close to the end of 2 one end of nut passed through by pivot pin, and perpendicular to pin
The axis direction of axis 1 passes through axis pin 1, meanwhile, nut 2 and the junction of axis pin 1 are equipped with packing ring, and the diameter of packing ring is more than pin
The diameter of axis, makes to be more uniformly stressed between nut and shackle 5.
In the description of scheme, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", " on ", " under ", " preceding ",
The orientation or position relationship of the instruction such as " rear ", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " be based on
