Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oil pipe joints, in particular to a cold-headed long oil pipe joint. Background Art
[0002] Cold-forged long oil pipe fittings are used to connect long oil pipes, manufactured using a cold-forging process. The cold-forging process utilizes the plastic deformation capacity of metal at room temperature. Using a mold to apply pressure to a metal blank, plastically deforming it within the mold cavity, the resulting part is molded to the desired shape and size. These fittings are widely used in the automotive, engineering, and petrochemical industries. In these fields, long-distance oil pipe connections are a common requirement, and cold-forged long oil pipe fittings, with their excellent performance and reliable connection, ensure stable system operation. Currently, most common oil pipe fittings utilize a single sealing structure. This single sealing structure is more susceptible to seal failure over extended periods of use or when exposed to factors such as pressure changes, temperature fluctuations, and vibration, leading to a waste of resources. Furthermore, most oil pipe fittings utilize threaded connections, requiring tools for installation and removal, and requiring a certain amount of torque for installation, making the operation relatively cumbersome.

[0026] The inner wall of the telescopic head 6 is fixedly connected with a spring 13, which is fixedly connected to the circular groove 8. The right surface of the connecting column 7 is provided with an annular groove 12. The inner wall of the circular groove 8 is provided with two arc grooves 10.

[0028] Working principle:
[0029] When the joint body 1 and the connecting pipe 2 are connected, the protective ring 3 is first pulled to the left to drive the sliding ring 23 to move together. The protective ring 3 and the sliding ring 23 are connected by two clamping blocks 20. During the movement, the sliding ring 23 will drive a group of connecting blocks 19 fixed to it to move together, compressing the two springs 22. At this time, a group of connecting blocks 19 will be separated from the limit of a group of limit blocks 14. The opposite surfaces of a group of limit blocks 14 are all magnet-designed and convex, which is convenient for the connection of the joint body 1. At this time, the joint body 1 is connected to the connecting pipe 2, and the connecting column 7 will squeeze a group of limit blocks 14. The left surface of the connecting column 7 is inclined. A group of limit blocks 14 is squeezed and will be completely engaged in a group of arc grooves 15. At this time, as the joint body 1 and the connecting pipe 2 are fully engaged, the magnetic ring 25 provided on the joint body 1 will generate suction with a group of limit blocks 14, and a group of limit blocks 14 will move relatively and fit into the magnetic ring 25. At this time, the sliding ring 23 is driven by the elastic force of the two springs 22. After reset, the sliding ring 23 will drive a group of connecting blocks 19 to reset and fit with a group of positioning blocks 24, and then limit and fix them. At this time, the joint body 1 and the connecting pipe 2 are in a limited and fixed state. The overall operation is simple and the connection is convenient. No complicated tools and tedious steps are required, which can greatly save time and improve work efficiency. During the connection process of the joint body 1 and the connecting pipe 2, the telescopic head 6 will contact the positioning block 24. The telescopic head 6 is squeezed to the right by the positioning block 24, compressing the spring 13, and the telescopic head 6 will expose the two arc grooves 10 opened in the circular groove 8 during the movement. At this time, the fluid can flow through the two arc grooves 10. The sealing ring 11 provided on the telescopic head 6 ensures that the telescopic head 6 blocks the fluid flow when reset. The double sealing design composed of the connection between the joint body 1 and the connecting pipe 2 and the telescopic head 6 ensures the high sealing of the connection, and can withstand higher pressure and impact force, ensure the stable operation of the system, and reduce the risk of failure caused by leakage or loose joints.
