Abstract

The invention discloses a vehicle tire inflating auxiliary device, and belongs to tools for mounting and dismounting air valves. The vehicle tire inflating auxiliary device comprises a sleeve a, a sleeve b, a hollow inner tube and a valve-core rotating bar. The sleeve a and the sleeve b are sleeved on the outer side of the inner tube, the valve-core rotating bar is inserted into the inner tube through the end of the inner tube. By the improved technology, the vehicle tire inflating auxiliary device has the advantages that before inflation, the valve core is mounted into the device through a valve core inlet port, and inflation and valve core mounting can be finished at one step without air leakage; the valve-core rotating bar can be used as a normal valve core key, the valve core can be mounted rapidly, and operation is facilitated; and a valve core ejector pin of the valve-core rotating bar can be used for opening an air hole of the valve core inside the device so that reinflation can be implemented without secondary operation.

Description

technical field [0001] The invention belongs to a tool for assembling and disassembling air valves, in particular to an auxiliary device for inflating tires of motor vehicles. Background technique [0002] At present, the inflation of automobile tires is mainly manual inflation, and the valve core is quickly screwed on the valve with the valve core key after inflation. In this way, when the valve core is installed, due to the high pressure in the tire and a large amount of gas leakage, the inflation cannot be completed at one time. Many unnecessary troubles prolong the maintenance time. Contents of the invention [0003] The present invention aims to overcome the deficiencies of the prior art, and provides a motor vehicle tire inflation auxiliary device which is easy to operate, does not leak inflated, completes inflation and valve core installation at one time, can monitor tire pressure in real time, is quick to install, and saves time. [0004] In order to achieve the ...
