Description
Technical field
The utility model is related to the accessories of engineering mechanical device, specially hydraulic cylinder earrings component.
Background technology
The piston rod of hydraulic cylinder is usually to be connect with earrings component, and junction, which also has, locks design, traditional earrings group
The locking that part uses is designed as nut check, and the mode of nut check is simple, but under the influence of by external factor, for example shake
Dynamic, impact, variable load or the influence of thermal stress, nut check are failures, and the connection of piston rod and earrings component is susceptible to pine
It is dynamic.
Utility model content
In view of the above technical problems, the utility model provides a kind of hydraulic cylinder earrings group that can improve reliable lock
Part.
What the utility model was achieved through the following technical solutions：Hydraulic cylinder earrings component, including earrings ontology, it is described
Earrings ontology is provided with inner screw sheath, and the inner screw sheath is connect with piston rod thread；It opens the end of the inner screw sheath
There is card slot, further include locking nut, lock ring and snap ring, locking nut, lock ring and snap ring are sequentially sleeved on the piston rod, institute
The snap ring one side stated is equipped with fixture block, and the fixture block is stuck in the card slot of the inner screw sheath end；The snap ring
Other side face is lock ring, and the lock ring inner wall has key, and keyway is provided on the piston rod, and the key is assemblied in described
Keyway in；The lock ring other side is locking nut, and locking nut is threadedly attached on the piston rod, and will
Snap ring, lock ring are locked on the end of inner screw sheath.
Further design, further includes pushing tow screw, the corresponding position of the lock ring, snap ring is provided with threaded hole, described
Pushing tow screw lock ring, snap ring are fixedly connected by being threadably mounted in the threaded hole searched of speed；The locking nut and lock
The one side of ring contact is equipped with the head of screw slot of annular, the ailhead for accommodating pushing tow screw.
Hydraulic cylinder earrings component provided by the utility model, increasing on the inside of locking nut has lock ring and snap ring, by ear
Ring body and piston rod are fixed to each other radially, are not susceptible to rotate, then fasten by locking nut, improve locking
Can, the connection of piston rod and earrings component is not easy to loosen.
Description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Fig. 1 is the cross-sectional view of the utility model.
Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
As shown in Figure 1, hydraulic cylinder earrings component, including earrings ontology, the earrings ontology are provided with inner screw sheath
2, the inner screw sheath 2 is threadedly coupled with piston rod 1；The end of the inner screw sheath 2 is provided with card slot, further includes locking screw
Mother 4, lock ring 5 and snap ring 6, locking nut 4, lock ring 5 and snap ring 6 are sequentially sleeved on the piston rod 1, the snap ring 6 one
Side is equipped with fixture block 7, and the fixture block 7 is stuck in the card slot of 2 end of inner screw sheath；The snap ring 6 other one
Side is lock ring 5, and 5 inner wall of lock ring has key 8, and keyway is provided on the piston rod 1, and the key 8 is assemblied in described
Keyway in；5 other side of lock ring is locking nut 4, and locking nut 4 is threadedly attached on the piston rod 1,
And snap ring 6, lock ring 5 are locked on the end of inner screw sheath 2.
The fixture block 7 of snap ring 6 is stuck in the card slot of 2 end of inner screw sheath, and the key 8 of lock ring 5 is assemblied in the keyway of piston rod 1
Interior, the two is connect with earrings ontology and piston rod 1 respectively, is fixed radially, is loosened to prevent mutually rotating.
In order to improve the reliability of locking, snap ring 6 and lock ring 5 are fixed together, the technological means used for：Further include
Pushing tow screw 3, the lock ring 5,6 corresponding position of snap ring are provided with threaded hole, and the pushing tow screw 3 is by being threadably mounted at
Lock ring 5, snap ring 6 are fixedly connected in the threaded hole that speed is searched；The one side that the locking nut 4 is contacted with lock ring 5 is equipped with ring
The head of screw slot of shape, the ailhead for accommodating pushing tow screw 3.By pushing tow screw 3 by snap ring 6 and lock ring 5 connect into one it is whole
Body, it is ensured that earrings ontology and piston rod 1 cannot find to relatively rotate radially, then be reinforced by locking nut 4.Locking nut
There are two 4 effects, and first is exactly to play the role of traditional locking, and second is exactly that snap ring 6 and lock ring 5 are carried out position to fix.
From the above is only the preferred embodiment of the utility model, it is noted that for the common of the art
For technical staff, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these
Improvement and modification also should be regarded as the scope of protection of the utility model.
