[0002] The automobile fuel filling pipe is an important part of the automobile fuel system. It consists of a fuel filling pipe and a vent pipe. One end of the fuel filling pipe is the fuel filling port, and the other end is connected to the fuel inlet of the fuel tank. When filling fuel, the fuel enters the fuel tank through the fuel filling pipe.

[0003] The fuel tank filling pipe of the automobile needs to be helium-tested during the production process. At this time, an air intake joint is needed to connect the fuel tank filling pipe and the helium testing equipment. The existing air intake joint for helium testing generally directly adopts a threaded locking method to connect the air intake joint to the fuel tank filling pipe, so as to improve the sealing of the connection between the throttle joint and the fuel tank filling pipe. However, this connection method is very troublesome to replace. The factory conducts online rapid detection and the shorter the time for rapid product replacement, the better. Every time the replacement is made, the staff needs to tighten the nut on the air intake joint, which greatly increases the replacement time. Utility Model Content
