Description

Technical Field

[0001] The utility model relates to the technical field of oil pipe connection, in particular to an anti-drop mechanism for a marine high-pressure oil pipe joint. Background Art

[0002] High-pressure oil pipes are an important part of high-pressure oil circuits. They have the characteristics of high pressure resistance and corrosion resistance. They usually have several forms such as ferrule type and internal thread flat type. High-pressure oil pipes are connected through high-pressure oil pipe joints. Therefore, the connection between high-pressure oil pipe joints and high-pressure oil pipes is very important.

[0003] For example, a Chinese patent with a publication (announcement) number of CN207830021U discloses a high-pressure oil pipe joint, including a joint body and a first joint, a second joint and a third joint located on the periphery of the joint body and respectively connected to the joint body, wherein the outer ends of the first joint, the second joint and the third joint are respectively provided with connecting portions connected to the high-pressure oil pipe, and the outer edges of the first joint, the second joint and the third joint are respectively provided with sealing cone portions adapted to the tapered holes of the high-pressure oil pipe, and a mounting seat for mounting and fixing the high-pressure oil pipe joint is provided on the joint body at the end opposite to the first joint, and a positioning portion that can be automatically positioned and installed is provided on one side of the mounting seat.

[0004] Although the above technical solution solves the corresponding technical problem, the above technical solution still has the following defects:
