The utility model provides a kind of oil pipe sealing ring with spiral drainage groove, it is related to oil pipe sealing ring technical field, including primary oil pipe, secondary oil pipe and primary flange ring, connecting mechanism is equipped between primary flange ring and secondary flange ring, sealing ring is equipped between primary oil pipe and secondary oil pipe, the inside of sealing ring is equipped with spiral groove, the inside of secondary flange ring is equipped with tensioning mechanism;The utility model is compressed after primary flange ring and secondary flange ring clamp primary oil pipe and secondary oil pipe, drive spring to be in compression state, spring generates the elastic force to drive sealing ring and secondary oil pipe to be close to primary oil pipe, so that primary oil pipe, secondary oil pipe and sealing ring are closely attached between, so that sealing effect is better, and primary flange ring and secondary flange ring are wrapped sealing ring, to solve the problem that outer ring of sealing ring in the prior art is easily damaged by scratching, and the sealing ring is broken in serious cases.

The utility model belongs to the field of machinery, and relates to an elastic plate hole clamping and adjusting device which comprises a lug hole penetrating elastic plate, a swing arm connecting piece, a supporting wheel swing arm, a lug hole penetrating piece and a lug plate blocking shifting pin, the lug hole penetrating elastic plate comprises a lug plate penetrating hole, a shifting pin penetrating and blocking sleeve is arranged at one end of the swing arm connecting piece, and a supporting wheel swing arm connecting structure is arranged at the other end of the swing arm connecting piece. The ear perforating piece is provided with a clamping and sticking elastic plate piece and a perforating ear, the perforating ear penetrates through the ear penetrating plate hole, the penetrating and blocking movement pin shaft sleeve penetrates through the ear penetrating plate hole, and the ear blocking plate movement pin penetrates through the perforating ear and the penetrating and blocking movement pin shaft sleeve, so that the clamping and sticking elastic plate piece is tightly attached to the ear penetrating hole elastic plate; the clamping and pasting elastic plate piece and the lug blocking plate moving pin prevent the perforated lug from falling off from a lug penetrating plate hole from the two sides of the lug penetrating hole elastic plate, the supporting wheel rocker arm is pushed by external force to be connected with the swing arm piece, the swing arm piece pushes the lug blocking plate moving pin, the lug blocking plate moving pin transmits the external force to the lug perforating piece, and the clamping and pasting elastic plate piece pushes the lug penetrating hole elastic plate to elastically deform and buffer. And the ear-hole-penetrating elastic plate is quickly straightened to reset by the buffer bounce of the ear-hole-penetrating elastic plate.
