Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a novel reverse supporting structure of a self-lubricating steel back bearing comprises an external connecting piece 1, a fixing block 2, an oil cylinder body 3, a sealing ring 4, a first oil port 5, a second oil port 6, an oil adding pipe 7, a lug 8, a piston rod 9, a piston block 10 and a steel back bearing body 11, wherein the fixing block 2 is fixed on the side of the external connecting piece 1, the oil cylinder body 3 is installed on the side of the fixing block 2, the sealing ring 4 is sleeved on the outer side of the fixing block 2, the first oil port 5 is arranged at the top of the fixing block 2, the second oil port 6 is fixed at the top of the oil cylinder body 3, the oil adding pipe 7 is installed on the fixing block 2 on the side of the oil cylinder body 3, the lug 8 is fixed on the inner wall of the oil cylinder body 3, the piston rod 9 is installed inside the oil cylinder body 3, the end of the piston rod;

The sealing ring 4 is arranged at the joint of the fixing block 2 and the oil cylinder body 3, and the sealing ring 4 is made of rubber, so that the sealing property of the connection of the fixing block 2 and the oil cylinder body 3 is improved, the lubricating oil is prevented from leaking during movement, and the normal operation of the device is ensured;

The section of the bump 8 is of an arc structure, the lowest point of the bump 8 is lower than the highest point of the piston block 10, the bump 8 can extrude lubricating oil in the oil storage box 101 out of the oil outlet seam 102, and the steel back bearing body 11 can be lubricated;

An oil storage box 101 is arranged inside the piston block 10, an oil outlet seam 102 is formed in the top of the oil storage box 101, a baffle plate 103 is arranged on the inner wall of the oil storage box 101, the side of the baffle plate 103 is connected with the inner wall of the oil storage box 101 through a spring 104, the oil storage box 101 and the baffle plate 103 are welded, the oil storage box 101 and the baffle plate 103 form a rotating structure, the oil adding pipe 7 can push the baffle plate 103 to rotate, lubricating oil is conveniently added, and when the piston block 10 moves, the baffle plate 103 can be always attached to the oil storage box 101 due to the resilience of the spring 104, and the lubricating oil is prevented from leaking;
