Abstract
The utility model discloses the hydraulic cylinders with self-locking function, including piston rod and connection component, connection component includes drive coupling and at least one reinforcement by connection device, tapped through hole is arranged on drive coupling and each reinforcement by connection device, there are gap between drive coupling and adjacent reinforcement by connection device, drive coupling is fixed with adjacent reinforcement by connection device by the first bolt.The utility model designs reinforcement by connection device, and reinforcement by connection device passes through tapped through hole with drive coupling and connect with piston rod, and is tied together reinforcement by connection device with drive coupling by the first bolt, while there are gaps between reinforcement by connection device and drive coupling.In the utility model, to guarantee that drive coupling does not occur returning pine, so that drive coupling is realized that first fixes again on the piston rod by the tapped through hole of drive coupling, realizes that second fixes again by reinforcement by connection device and the first bolt.The utility model can be widely applied to hydraulic transmission technology field.
Description
Technical field
The utility model relates to hydraulic transmission technology fields, in particular to the hydraulic cylinder of self-locking function.
Background technique
In edger, the piston rod and connector of hydraulic cylinder lead to the outer tooth of connector and piston rod because of frequently movement
Between be easy to appear and return loose phenomenon, it is unstable so as to cause the transmission of hydraulic cylinder, influence the working efficiency of hydraulic cylinder.
Utility model content
The technical problem to be solved by the utility model is to provide the hydraulic cylinders with self-locking function, pass through piston rod and company
Connecing the self-locking of device prevents from returning pine, and the transmission efficiency of hydraulic cylinder can be improved.
Used technical solution to solve above-mentioned technical problem:
Hydraulic cylinder with self-locking function, it is described including piston rod and the connection component for being arranged in the piston-rod end
Connection component includes drive coupling and at least one reinforcement by connection device, in the drive coupling and each reinforcement by connection device
Be arranged with for the piston rod screw in tapped through hole, between the drive coupling and adjacent reinforcement by connection device there are
Gap, the drive coupling are fixed with adjacent reinforcement by connection device by the first bolt.
Further, the reinforcement by connection device includes flange arrangement.
Further, the quantity at least two of the reinforcement by connection device is bonded to each other between adjacent reinforcement by connection device.
Further, the quantity at least two of the reinforcement by connection device, there are gaps between adjacent reinforcement by connection device.
Further, it is fixed between adjacent reinforcement by connection device by the second bolt.
The utility model has the advantages that the utility model designs reinforcement by connection device, reinforcement by connection device and drive coupling are logical by screw thread
Hole is connect with piston rod, and is tied together reinforcement by connection device with drive coupling by the first bolt, while reinforcement by connection device
There are gaps between drive coupling.In the utility model, to guarantee that drive coupling does not occur returning pine, pass through transmission connection
The tapped through hole of device makes drive coupling realize that first fixes again on the piston rod, is realized by reinforcement by connection device and the first bolt
Second fixes again.The utility model can be widely applied to hydraulic transmission technology field.
Detailed description of the invention
Fig. 1 is the installation diagram of connection component and piston rod；
Fig. 2 is the structure chart of connection component；
Fig. 3 is the side view of connection component；
Fig. 4 is the exploded view of connection component.
Specific embodiment
The utility model is described further below with reference to Fig. 1 to Fig. 4.
Hydraulic cylinder with self-locking function, including piston rod 1 and the connection component for being arranged in 1 end of piston rod, institute
Stating connection component includes drive coupling 21 and at least one reinforcement by connection device 22, the drive coupling 21 and each connection
The tapped through hole screwed in for the piston rod 1 is arranged on reinforcing device 22.
The reinforcement by connection device 22 includes flange arrangement, between the drive coupling 21 and adjacent reinforcement by connection device 22
There are gap, the drive coupling 21 is fixed with adjacent reinforcement by connection device 22 by the first bolt.It is adjacent in the present embodiment
It is bonded to each other between reinforcement by connection device 22.In other embodiments, between adjacent reinforcement by connection device 22 can also there are gaps, and
It is fixed between adjacent reinforcement by connection device 22 by the second bolt.In the present embodiment, the quantity of the reinforcement by connection device 22 is one.
The utility model realizes that the process of self-locking function is as follows:
1, drive coupling and reinforcement by connection device are tied down with the first bolt, there are gaps therebetween；
2, piston-rod end is successively screwed in the threaded hole of drive coupling and reinforcement by connection device；
3, the nut of the first bolt is tightened.
By above three step i.e. complete it is self-locking, hydraulic cylinder at work, between drive coupling 21 and piston rod 1 not
Loose phenomenon can be returned.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to
State embodiment, within the scope of knowledge possessed by those of ordinary skill in the art, can also do not depart from it is practical
Various changes can be made under the premise of novel objective.
