This dismantles the device as needs, when realizing adding lubricating oil in the lubricating system, at first realize the drainage to 2 internal pressure of connecting rod through adjustment mechanism to make gasbag 4 through the restoring force of first spring 6, reply to initial state, at this moment can rotate rotor plate 1, rotor plate 1 drive connecting rod 2 removes, make connecting rod 2 now keep away from the direction removal of counter sink, make connecting rod 2 keep away from the counter sink, at this moment can realize the interpolation to the main part.

After the adding is finished, the rotating plate 1 is moved, so that the rotating plate 1 is arranged above the countersunk hole, the bottom end of the pushing rod 7 is positioned in the countersunk hole and is abutted against the countersunk hole, at this time, the rotating plate 1 is rotated, the connecting rod 2 is driven to rotate by the rotating plate 1, at this time, the pushing rod 7 moves towards the rotating plate 1, the pushing rod 7 drives the sealing plate 21 to slide in the connecting rod 2, at this time, because the sealing plate 21 is in sliding and sealing connection with the connecting rod 2, at this time, air positioned between the sealing plate 21 and the top end of the connecting rod 2 enters the corrugated pipe 8 through the communicating pipe 10 and then flows into the air bag 4, so that the air bag 4 is deformed, thereby reducing the gap between the air bag 4 and the connecting rod 2, increasing the contact area between the air bag 4 and the connecting rod 2, and further improving the sealing effect and the fixing effect, at this time, through the abutting of the pushing rod 7 and the countersunk hole, the realization is sealed to the one-level of main part, realize sealed to the second grade of main part through gasbag 4, here through setting up locating lever 9 at the cylindrical recess, be used for realizing spacing to bellows 8, prevent that bellows 8 is at the torsional phenomenon of process of removal, realize the protection to bellows 8, here through setting up gasket 5 between rotor plate 1 and sealing ring 3, not only can promote fixed effect, can also realize communicating pipe 10 and 8 protection of bellows simultaneously, prevent to crush bellows 8 at fixed in-process, can also make gasbag 4 have a sufficient inflation space simultaneously.

Here when the pressure to the inside of connecting rod 2 is discharged, at first, promote handle 13 and remove towards the direction of catch bar 7, handle 13 drive bull stick 14 removes, bull stick 14 drive screw block 15 removes, screw block 15 drive slider 18 removes, slider 18 drive branch 17 removes, branch 17 drive sealed piece 19 removes, make sealed piece 19 and connecting block 16 separation, at this moment the inside air of connecting rod 2 will get into in the gag lever post 11 through the intercommunicating pore, then in getting into bull stick 14, the venthole through bull stick 14 top flows, can realize the discharge to the inside pressure of connecting rod 2, thereby be convenient for realize the dismantlement to connecting rod 2, reduce the dismantlement degree of difficulty, the practicality of use has been improved, here through adjustment mechanism, realize the regulation to different pressures in connecting rod 2, promote the fixed effect of connecting rod 2.

Be located convenient exhaust here, handle 13 can rotate, handle 13 drive bull stick 14 rotates, bull stick 14 drive screw thread piece 15 rotates, make internal thread connection on screw thread piece 15 and the gag lever post 11, can realize at this moment the spacing to screw thread piece 15, can realize at this moment the automatic exhaust to connecting rod 2 inside, need not press handle 13 all the time, reduce intensity of labour, at this moment second spring 20 is in compression state, restoring force through second spring 20, not only can make the better gag lever post 11 of screw thread piece 15 connect, simultaneously under initial state, make sealed piece 19 support with connecting block 16 all the time and lean on, promote sealed effect.

Compared with the prior art, the lubricating oil filling device for oil exploitation realizes the sealing of the main body through the matching of the sealing mechanism and the adjusting mechanism, wherein the first-stage sealing of the main body is realized through the end face of the push rod 7, the fixing of the connecting rod 2 is realized through the external thread on the outer ring of the connecting rod 2, the movement of the connecting rod 2 is prevented, the deformation generated after the air bag 4 is inflated is used for reducing the gap between the air bag 4 and the connecting rod 2 and increasing the contact area between the air bag 4 and the connecting rod 2, thereby improving the sealing effect and the fixing effect, realizing the second-stage sealing of the main body and preventing the waste caused by the overflow of the main body, the adjustment of different pressures in the connecting rod 2 is realized through the adjusting mechanism, the fixing effect of the connecting rod 2 is improved, meanwhile, the air bag 4 is returned to the initial state through the pressure in the connecting rod 2, and the disassembly of the connecting rod 2 is facilitated, the disassembly difficulty is reduced, and the practicability of use is improved.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
