Problems solved by technology
During the welding process, there may be bad phenomena such as virtual welding and missing welding, which will affect the sealing performance of the automobile air-conditioning pipe, and the aluminum alloy pipe after welding is easily deformed, resulting in the geometric dimensions of the automobile air-conditioning pipe during assembly cannot meet the requirements, and the defective rate higher
Even if the welding quality of the automobile air-conditioning pipe is very good, it is easy to cause cracks in the weld during transportation or assembly, which affects the sealing of the automobile air-conditioning pipe and increases the risk of leakage

The invention discloses an automotive air conditioning pipe joint mechanism avoiding leakage. The automotive air conditioning pipe joint mechanism comprises a pipe body and a joint, wherein the pipe body and the joint are connected in a riveted mode; the pipe body comprises a main pipe part and a pipe expanding part located at the end of the main pipe part, the pipe expanding part is formed by flaring the main pipe part, the pipe diameter of the pipe expanding part is greater than the pipe diameter of the main pipe part, and the pipe expanding part and the main pipe part are connected through a transition part; the joint comprises an end cap and a hexagonal prismoid body, the end cap and the hexagonal prismoid body are respectively of a hollow structure, a first cavity is formed in the end cap, a second cavity is formed in the hexagonal prismoid body, the pipe expanding part is located in the second cavity, the main pipe part penetrates through the first cavity to extend outwards, the outer wall of the pipe expanding part is attached to the inner wall of the hexagonal prismoid body, and the portion, located in the first cavity, of the outer wall of the section of the main pipe part is attached to the inner wall of the end cap; and an external thread is arranged on the outer wall of the hexagonal prismoid body. According to the automotive air conditioning pipe joint mechanism, the leakage problem is completely solved, the production efficiency is improved, and the enterprise benefits can be improved.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to an auto air conditioner pipe joint mechanism for avoiding leakage. Background technique [0002] With the improvement of people's living standards, the penetration rate of automobiles is getting higher and higher, and the automobile industry is also developing rapidly. Existing automobile, the connection between the aluminum alloy pipe in its automobile air conditioner and the nut joint mainly adopts the mode of welding (brazing) to complete. During the welding process, there may be bad phenomena such as virtual welding and missing welding, which will affect the sealing performance of the automobile air-conditioning pipe, and the aluminum alloy pipe after welding is easily deformed, resulting in the geometric dimensions of the automobile air-conditioning pipe during assembly cannot meet the requirements, and the defective rate higher. Even if the welding quality of the autom...
