Description

Technical Field

[0001] The utility model relates to the technical field of pipe joints, in particular to a vehicle pipe joint. Background Art

[0002] Cars are already common in our lives, and they are gradually moving from gasoline-powered cars to new energy cars. Whether it is air conditioning or exhaust in the car, connecting pipes are needed to connect them so that the car can exhaust and transmit gas. In the process of connecting pipes, joints are needed;

[0003] During the use of the existing joints, the threads on the surface of the joints and the threads on the inner wall of the pipe ports are threadedly connected to complete the installation and connection of the pipes and achieve the purpose of fixing the pipes. During the driving process, the car is prone to shaking due to the impact of the bumpy road surface. When the car shakes, the connecting pipes are also prone to shaking. Over time, the threads of the pipes and the joints are prone to loosening, thereby causing the pipes to leak and affecting the normal use of the vehicle. For this reason, we propose a vehicle pipe joint. Utility Model Content
