Automobile speed sensor mounting structure

The utility model provides an automobile speed sensor mounting structure, which relates to the technical field of speed sensors and comprises a protective shell, sliding grooves are formed in the top and the bottom of the outer surface of the protective shell, and sliding blocks are embedded in the two sliding grooves in a sliding manner. When the device is used, firstly, the speed sensor is movably embedded in the protective shell and is movably embedded into the multiple air bags, at the moment, a worker rotates the rotary handle to take out the sealing threaded rod from the interior of the air inlet pipeline, and at the moment, the worker injects air into the air inlet pipeline through a tool; the multiple air bags are in an expansion state, so that the position of the speed sensor is fixed, a worker can conveniently install the speed sensor, and when the speed sensor is used for a period of time and needs to be disassembled, air in the multiple air bags can be exhausted through the air inlet pipeline. 本实用
