When lubricating oil needs to be added, the sealing cover can be opened, and lubricating oil can be injected into the oil storage box 4 through the oil filling pipe, a sleeve 18 is arranged on the top of the inner side of the piston A12, and a conduit 16 extending to the inside of the oil storage box 4 is sleeved on the bottom of the sleeve 18, and oil inlet holes are opened at the bottom of both sides of the conduit 16, so that the lubricating oil in the oil storage box 4 can enter the conduit 16 from the guide hole, and a baffle 14 is arranged on the bottom of the outer side of the conduit 16;

[0026] A piston B17 is provided at the top of the conduit 16, a one-way valve C15 connected to the conduit 16 is provided at the top of the piston B17, a one-way valve D19 is provided at the top of the inside of the sleeve 18, and delivery pipes 20 connected to the one-way valve D19 are provided at the tops of both sides of the sleeve 18.

[0027] Working principle: When the device is in use, the motor 5 can be started to run, and the motor 5 can drive the rotating shaft 3 to rotate, and then the rotating shaft 3 drives the U-shaped curved rod 2, so that the U-shaped curved rod 2 can drive the piston A12 to reciprocate up and down under the connection of the two sets of hinged rods 6. When the piston A12 moves down, the refrigerant can push the one-way valve A8 to open and enter the piston cylinder 7 under the action of negative pressure, and when the piston A12 moves up, the refrigerant can be compressed. At this time, the one-way valve A8 is automatically closed, and the one-way valve B11 can be opened under the action of pressure to discharge the refrigerant compressed by the piston cylinder 7;

When the piston A12 moves downward, the conduit 16 can be driven downward. When the conduit 16 and the When the bottom of the oil storage box 4 contacts, the sleeve 18 can be pushed to move downward along the outside of the piston B17. At this time, the one-way valve C15 is automatically closed, and the one-way valve D19 can be opened under the action of pressure to squeeze out the lubricating oil in the sleeve 18 and transport it to the lubrication groove 13 through the diversion of the delivery pipe 20, so that when the piston A12 moves up and down, the inner wall of the piston cylinder 7 can be lubricated, the friction between the piston cylinder 7 and the piston A12 is reduced, the power consumption is reduced, and the automatic lubrication of the lubrication groove 13 is realized without consuming additional driving force, saving the consumption of driving components.
