Technical Field

[0001] The utility model relates to the technical field of tire valve dust caps, in particular to a tire valve dust cap with a safety protection structure. Background Art

[0002] The tire valve is a device used to inflate or release gas or liquid in a tire. It is a one-way valve that can maintain and detect internal pressure. The main function of the tire valve is to inflate or release gas in the tire and maintain the seal after the tire is inflated. It can isolate the air and prevent dust, water, oil, etc. from damaging the valve core sealing rubber, thereby extending the service life of the valve core. A dust cap is used when the tire valve is used.

[0003] A tire explosion-proof valve is disclosed in the Chinese utility model patent application number: CN201821538232.2, which is connected to the inflation nozzle of the automobile pneumatic tire. It is arranged outside the inflation nozzle of the pneumatic tire and is an extension of the pneumatic tire inflation nozzle. It is very convenient to install, use, adjust and replace.

[0004] Although the above patent realizes the function of assisting the use of the tire valve, the above patent has the following disadvantages when used: the mouth cap of the above tire explosion-proof tire valve is usually connected to the valve mouth by a single thread when in use, the fixing effect is relatively general, and there is no anti-lost mechanism. The mouth cap is very easy to lose when the mouth cap is unscrewed to inflate the tire, which is inconvenient to use. Therefore, we propose a tire valve dust cap with a safety protection structure.
