High-pressure precise oil pipe joint for motor vehicles

Abstract

The invention relates to a high-pressure precise oil pipe joint for motor vehicles. The high-pressure precise oil pipe joint is characterized in that the high-pressure precise oil pipe joint comprises an outer pipe, a first connecting pipe body, a second connecting pipe body and a sealing assembly, the interior of the outer pipe is hollow, the two ends of the outer pipe are open, the end part of the first connecting pipe body extends to the interior of the outer pipe and is detachably connected with the end part of the outer pipe, a first oil passing hole and a second oil passing hole are formed in the first connecting pipe body and the second connecting pipe body, the second connecting pipe body comprises an extension part, a limiting linkage part and a pipe body connecting part, the extension part extends into the first oil passing hole, the radial value of the limiting linkage part is larger than that of the extension part, a locking step is arranged on the inner circumference of the outer pipe, and the two sides of limiting linkage part are connected with the end part of the first connecting pipe body and the locking step in abutting mode correspondingly. The high-pressure precise oil pipe joint for the motor vehicles has the beneficial effects that provided the high-pressure precise oil pipe joint for the motor vehicles has good sealing performance, and oil leakage is prevented.

Description

technical field [0001] The invention relates to the technical field of hydraulic pipe joints, in particular to a high-pressure precision oil pipe joint for motor vehicles. Background technique [0002] Nowadays, automobiles can be said to be one of the very common means of transportation. The development of economy and society promotes the continuous optimization of automobiles. Among them, the joints of oil pipes should not be underestimated. It is directly related to the operation of the car. If the joint design is unreasonable, it will There will be leakage, which not only has certain hidden safety hazards, but also wastes certain resources and brings corresponding economic losses. [0003] Most of the existing automobile oil pipe joints adopt the interface with screw fit, and an inner screw that cooperates with the outer screw of the oil pipe is set at one end of the oil pipe to realize the connection of the oil pipe; When it is large, there will inevitably be gaps, whi...

[0002] Nowadays, automobiles can be said to be one of the very common means of transportation. The development of economy and society promotes the continuous optimization of automobiles. Among them, the joints of oil pipes should not be underestimated. It is directly related to the operation of the car. If the joint design is unreasonable, it will There will be leakage, which not only has certain hidden safety hazards, but also wastes certain resources and brings corresponding economic losses.

[0003] Most of the existing automobile oil pipe joints adopt the interface with screw fit, and an inner screw that cooperates with the outer screw of the oil pipe is set at one end of the oil pipe to realize the connection of the oil pipe; When it is large, there will inevitably be gaps, which will affect the airtightness of the oil pipe joints, and oil leakage at the oil pipe joints is easy; and the oil pipe joints are often accompanied by vibration during use, and leakage will occur at the oil pipe joints during the vibration process , when there is leakage and it is impossible to replace the oil pipe or the oil pipe joint, the whole oil pipe and the oil pipe joint can only be replaced together; so we designed the oil pipe joint to solve the above problems
