Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure oil pipe joints, in particular to an explosion-proof high-pressure oil pipe joint. Background Art

[0002] High-pressure oil pipes are part of the high-pressure oil circuit. They are required to withstand a certain oil pressure and have a certain fatigue strength to ensure the sealing requirements of the pipeline. Automotive high-pressure oil pipes are mainly found in high-pressure injection diesel engines and high-pressure injection direct injection gasoline engines, and can withstand the oil pressure required during engine operation.

[0003] Existing oil pipe joints are threaded, but the oil pipe will generate large vibrations during operation. Using only threaded connections for the pipe is not enough to ensure its sealing. The threaded connections are easy to loosen, and the loosened oil pipe will have certain cracks, which will burst under high-pressure environments. The oil path in the oil pipe is also prone to leakage, affecting its use. Utility Model Content

However, the oil pipe will generate large vibrations during operation. Only the threaded connection of the pipeline is not enough to meet its sealing requirements. The threaded connection is easy to loosen. The loosened oil pipe will have certain cracks and burst under high-pressure environment. The oil path in the oil pipe is also prone to leakage, affecting its use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an explosion-proof high-pressure oil pipe joint, comprising a joint body, wherein both sides of the joint body are fixedly connected with threaded interfaces, the bottom of the joint body is fixedly connected with a connecting seat, the inner side of the connecting seat is fixedly connected with a connecting shaft, the two side surfaces of the connecting shaft are rotatably connected with a hoop 1, the inner side of the hoop 1 is fixedly connected with a rubber pad 1, the top of the hoop 1 is fixedly connected with a mounting block, the inner side of the mounting block is provided with a mounting groove, the inside of the mounting groove is rotatably connected with a rotating shaft, the surface of the rotating shaft is fixedly connected with a screw rod, the surface of the screw rod is threadedly connected with a hand-tightening nut, the two side surfaces of the connecting shaft are rotatably connected with a hoop 2, the inner side of the hoop 2 is fixedly connected with a rubber pad 2, the top of the hoop 2 is fixedly connected with a fixing block, and the inner side of the fixing block is provided with a fixing groove.

[0008] By adopting the above technical solution, hoop one, hoop two, etc. are provided for use in conjunction with rubber pad one and rubber pad two. Hoop one and hoop two can drive rubber pad one and rubber pad two, approaching each other, thereby tightening and fixing the part connecting the oil pipe and the threaded interface. Rubber pad one and rubber pad two have a shock-absorbing effect, which can prevent loosening caused by vibration, improve the stability of the connection, avoid bursting, and facilitate use.

[0009] Preferably, the shape and size of the rubber pad 1 are the same as those of the rubber pad 2, and the rubber pad 1 and the rubber pad 2 are symmetrically arranged.
