Description

Technical Field

[0001] The utility model relates to the technical field of joints, in particular to an aluminum joint for air circuit testing of new energy buses. Background Art

[0002] The air circuit inspection of new energy buses mainly includes the high-voltage wire harness pressure resistance and air tightness test. When conducting the high-voltage wire harness pressure resistance and air tightness test, the test process usually consists of four stages: inflation, stabilization, inspection, and exhaust. The current exhaust solution after inspection is to remove the joint and release the gas, which is very labor-intensive and time-consuming. Therefore, a joint that can be exhausted without disassembly is very necessary.

[0003] The existing patent (Announcement No.: CN213117853U) proposes an aluminum joint for automobile air conditioning filter, including a first aluminum joint, a second aluminum joint, a connecting pipe and a rubber sealing ring. The connecting pipe is connected to the first aluminum joint and the second aluminum joint by threads. The second aluminum joint is threadedly connected to the upper part of the first aluminum joint, between the first aluminum joint and the second aluminum joint, and a rubber sealing ring is arranged on the outer periphery of the connection of the connecting pipe. The outer periphery of the rubber sealing ring is provided with a plug-in column that is integrated with the bottom of the second aluminum joint. The plug-in column is threadedly connected in the slot of the first aluminum joint. The bottom of the first aluminum joint is provided with a support that is integrated with the first aluminum joint. The plug-in column and the slot of the utility model can enhance the sealing performance of the rubber sealing ring on the connection of the connecting pipe, and can effectively fix the position of the rubber sealing ring, and enhance the air tightness of the connection between the first aluminum joint and the second aluminum joint. The utility model has a reasonable design, a stable structure, and a strong air tightness of the connection.

[0004] The above-mentioned joint adopts a plug-in column and a slot in the technical solution to solve the airtightness problem, which can enhance the sealing performance of the rubber sealing ring on the connection of the connecting pipe, and can effectively fix the position of the rubber sealing ring, and enhance the airtightness of the connection between the first aluminum joint and the second aluminum joint. The problem with this solution is that it solves the airtightness problem, but cannot solve the problem of gas emissions after the bus air circuit test. Therefore, we propose an aluminum joint for new energy bus air circuit testing to solve the above problem. Utility Model Content
