Pipe 47 is pumped into the top of the first hydraulic tube 45.
It please refers to shown in Fig. 1-Fig. 4, in the present embodiment, hydraulic cylinder 43 includes upper valve body 431, lower valve body 432, oil storage room
433 and the first oil guide pipe 435 and the second oil guide pipe 436 that are installed in oil storage room 433, upper valve body 431,432 and of lower valve body
Oil storage room 433 encloses a closed space jointly, for storing hydraulic oil and carrying out hydraulic oil with the first hydraulic tube 45
Exchange.
In the present embodiment, the bottom end of the second hydraulic tube 46 abuts and seals with the top of upper valve body 431.It can prevent liquid
Pressure oil leaks, to increase the reliability of the present apparatus.
Oil pump 44 is installed on lower valve body 432, and the oil inlet of oil pump 44 is located in oil storage room 433, before the use, can be by
Air in one hydraulic tube 45, oil storage room 433 and other oil circuits is all discharged, and then fills hydraulic oil, oil pump 44 is always
It is immersed in hydraulic oil.Lower valve body 432 offers the first oil circuit 4320 and the second oil circuit 4321, and upper valve body 431 offers third
One end of oil circuit 4310 and the 4th oil circuit 4311, the first oil circuit 4320 is connected to oil pump 44, the other end of the first oil circuit 4320 with
One end of first oil guide pipe 435 is connected to, and the other end of the first oil guide pipe 435 is connected to third oil circuit 4310, third oil circuit 4310
Be connected to far from one end of the first oil guide pipe 435 with the bottom of oil pipe 47, one end of the second oil circuit 4321 is connected to oil pump 44, the
The other end of two oil circuits 4321 is connected to one end of the second oil guide pipe 436, the other end and the 4th oil circuit of the second oil guide pipe 436
One end far from the second oil guide pipe 436 of 4311 connections, the 4th oil circuit 4311 is connected to the first hydraulic tube 45, needs to illustrate
It is that for oil pump 44 here when operating, the effect that the first oil circuit 4320 and the second oil circuit 4321 generate is on the contrary, namely
It says, when hydraulic oil is delivered up by the first oil circuit 4320, the second oil circuit 4321 can be defeated into oil storage room 433 by hydraulic oil
Send, conversely, when the first oil circuit 4320 by hydraulic oil to oil storage room 433 convey when, the second oil circuit 4321 can by hydraulic oil to
Upper conveying allows hydraulic oil to form up and down smoothly circulation.
Further, the first check valve 4312 is installed, the first check valve 4312 makes third oil circuit in third oil circuit 4310
