Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to an anti-dropping fixing clamp for a high-pressure oil pipeline joint. Background Art

[0002] High-pressure oil pipes are important components of high-pressure oil circuits of some large-scale mechanical equipment. They have special properties such as high pressure resistance and corrosion resistance. High-pressure oil pipes are connected through high-pressure oil pipe joints. Therefore, high-pressure oil pipe joints play an important role in the connection of high-pressure oil pipes.

[0003] At present, most pipelines are connected by threads. However, high-pressure oil pipe joints usually work in harsh environments and have high internal oil pressure. After long-term use, vibrations in the high-pressure oil pipes can easily loosen the high-pressure oil pipe connection joints, causing the oil pipes to loosen and fall off. When the oil pipes fall off instantly, it is easy to cause harm to the operating personnel. Therefore, we propose a high-pressure oil pipe joint with an anti-fall-off structure.
