The invention relates to the technical field of tire pressure monitoring, and discloses an external rotary joint for rotating an automobile wheel. The external rotary joint comprises an air inlet seat, wherein an air inlet seat extends upwards to form a connecting shaft, and a first through hole and an airflow channel are formed in the connecting shaft and the air inlet seat; a connecting part isconnected below the air inlet seat, and a second through hole is formed in the connecting part; the first through hole and / or the second through hole is provided with internal threads; the fixing device comprises a driving shaft and a plurality of clamping claws, and the clamping claws are hinged to the connecting part; and outer threads are arranged on a driving shaft arranged in the first through hole and the second through hole, the driving shaft can move up and down in the first through hole and the second through hole, and the bottom of the driving shaft is connected with a driving block;an air outlet ring sleeves the connecting shaft and can rotate around the connecting shaft; an air outlet communicating with the air flow channel is formed in the air outlet ring, and sealing parts are arranged at the two ends of the air outlet ring. The external rotary joint has the advantages of being simple in structure, reliable in connection and capable of effectively solving the problem ofdifficulty in rotating wheel gas pipes in rotation.
Description
technical field [0001] The invention relates to the technical field of tire pressure monitoring, in particular to an external rotary joint for rotating automobile wheels. Background technique [0002] When the car is running, when the tire pressure is too high, the contact area between the tire and the ground will be reduced, which will lead to a decrease in the grip of the wheel; shorten the service life of tires. Therefore, more and more passenger cars are now equipped with a tire pressure monitoring function, which monitors the tire pressure of the wheels in real time during driving. [0003] There are mainly two types of existing tire pressure detectors: built-in tire pressure detectors and external tire pressure detectors; among them, the external tire pressure detectors are generally plugged into the air nozzles of the wheels, and the pressure sensors monitor the tire pressure in real time. However, in the fast rotation of the wheel, since the external tire pressure ...
