Description

Matching structure of high-pressure oil pipe joint nut and compression washer Technical Field The utility model belongs to the technical field, and particularly relates to a matching structure of a high-pressure oil pipe joint nut and a compression washer. Background When the high-pressure oil pipe is used, the high-pressure oil pipe is often communicated with an external pipeline by utilizing a matching structure of the pipe joint nut and the compression washer. The prior pipe joint nut and the pressing washer are matched with each other, although the high-pressure oil pipe and the external pipeline are fixedly connected and hermetically connected, the matching structure can be prevented from rotating independently and loosening, so that the firmness and the tightness of the joint of the high-pressure oil pipe and the external pipeline are prevented from being influenced, the adopted anti-loosening structure is often realized in a mode that the connecting structure cannot be reversely screwed through the matching of the clamping structure, the effect of connecting the high-pressure oil pipe and the external pipeline can be ensured, the user cannot conveniently realize the detachment of the loosening structure, and the user cannot conveniently separate the high-pressure oil pipe from the external pipeline later, so that the use requirement of people cannot be repeatedly met. Disclosure of utility model In view of the above, the utility model provides a matching structure of the high-pressure oil pipe joint nut and the compression washer, which aims at the defects of the prior art, not only can firmly connect the high-pressure oil pipe with the external pipeline and avoid the automatic looseness of the connection part of the high-pressure oil pipe and the external pipeline, but also can enable a user to conveniently realize the disassembly of the high-pressure oil pipe and the external pipeline, thereby more fully meeting the use demands of people. In order to solve the technical problems, the technical scheme includes that the high-pressure oil pipe joint nut and pressing washer matching structure comprises a nut body arranged at the side end of a high-pressure oil pipe, a threaded connecting pipe in threaded connection with the nut body is arranged at the side end of an external pipeline, a fixing ring plate matched with the nut is further arranged at the side end of the external pipeline, a first washer body is arranged at the side end of the nut body, a second washer body matched with the first washer body is arranged at the side end of the fixing ring plate, an L-shaped mounting frame is further arranged on the high-pressure oil pipe, a mounting groove is formed in the mounting frame, an adjusting screw is rotatably arranged in the mounting groove, a mounting block in sliding connection with the mounting groove is in threaded connection with the adjusting screw, and a pressing plate used for limiting and fixing the fixing ring plate is arranged on the mounting block.
