Problems solved by technology
[0004] The structure of the tire inflation nozzle with the above-mentioned structure is relatively complicated, and the cost is high. At the same time, the metal fatigue of the spring clamp will occur after a period of use, and the elasticity will be poor, which will affect the use effect; at the same time, the spring clamp and the external thread of the valve will be worn. , resulting in the problem of external thread slippage

A tire inflation valve comprises a valve body. An air outlet hole and a valve insertion hole are formed in the valve body, locking grooves communicating with the valve insertion hole are formed in thetwo sides of the valve insertion hole, and a locking block is pivoted in the locking groove in each side. One-way tooth ripples are arranged on the inner sides of the locking blocks, and locking springs are arranged between the outer sides of the locking blocks and the side walls of the locking grooves. The locking springs press the one-way tooth ripples on the inner sides of the locking blocks to the valve insertion hole so that the one-way tooth ripples can be located in the valve insertion hole. Unlocking driving blocks are further connected in the locking grooves in a pivoted mode, driving parts of the unlocking driving blocks stretch out of the valve body from end openings in the outer side of the locking grooves, and executing parts of the unlocking driving blocks are matched with the locking blocks. The driving parts or the unlocking driving blocks are pressed, and the locking blocks are driven through the executing parts to extrude the locking springs, so that the locking blocks are integrally contracted into the locking grooves. As a locking mode that the springs are matched with the locking blocks is adopted, the problem of metal fatigue does not exist, the size of the inflation valve is greatly reduced, and the inflation valve has the advantages of being reasonable in structure, convenient to use and durable.
Description
technical field [0001] The invention relates to a tire inflation tool, in particular to a tire inflation nozzle. Background technique [0002] The tire inflation nozzle is mainly used to inflate automobiles and other vehicles. The current tire inflation nozzle generally includes a valve sleeve and a valve core. There is a wrench-type locking mechanism. When in use, align the port of the valve sleeve with the air nozzle of the wheel lift, pull the wrench-type locking mechanism to lock the entire tire inflation nozzle on the air nozzle, and then turn on the air source switch. The tire can be inflated. Because the current inflation nozzle adopts a wrench-type locking mechanism, the inflation nozzle is locked by the cooperation of the wrench locking mechanism and the external thread of the tire gas nozzle. The wrench-type locking mechanism is one-sided. The tire valve is clamped, which is prone to wear and tear during use and cannot be locked, and the service life is short. ...
