Movable tire inflator pump mechanism capable of preventing excessive inflation

Abstract

The invention relates to the technical field of tire inflation, and discloses a movable tire inflator pump mechanism capable of preventing excessive inflation. The movable tire inflator pump mechanismcomprises a shell, the left side of the shell is movably connected with a power line, the right side of the shell is movably connected with an inflation tube, one side, away from the shell, of the inflation tube is fixedly connected with an inflation head, and the top of the shell is movably connected with a first button. According to the movable tire inflator pump mechanism capable of preventingexcessive inflation, after the air pressure in a tire reaches a normal value, at the moment, a piston rod drives an extrusion block to move downwards, so that the extrusion block extrudes the right side of a movable block, the movable block further extrudes a contact, and an inflator pump stops working; therefore, the effect of preventing tire explosion caused by too high air pressure when the tire is inflated is achieved; at the moment, the air pressure in a second inner chamber is larger than that in an air inlet, the movable block drives a first groove to move leftwards, the second inner chamber is not in communication with the interior of the air inlet, and therefore the effect of preventing inflated tires from leaking air is achieved.

Description

Technical field [0001] The invention relates to the technical field of tire inflation, in particular to a mobile tire inflation pump mechanism for preventing over-inflation. Background technique [0002] In daily life, we often encounter the situation of vehicle tires being out of air. At this time, people need to use air pumps, air pumps, etc. to inflate the vehicle tires, and the air pump is a common way to inflate the tires using the principle of atmospheric pressure. Inflatable equipment. [0003] In the process of using an inflator to inflate a tire, people are required to wait quietly for a while. When the pressure inside the tire is normal, turn off the inflator and remove the inflator nozzle of the inflator. In the process, if people fail to turn off the inflation pump in time, it is likely to cause the tire internal pressure to be too high, which may cause the tire to explode, and it will also pose a great threat to people's safety. How to prevent the tire pressure from b...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a mobile tire air pump mechanism for preventing overinflation, which has the advantage of preventing the tire from exploding due to excessive air pressure during tire inflation, and solves the problem of tire inflation during the tire inflation process using the air pump. People fail to forget to turn off the air pump in time, which may cause the internal pressure of the tire to be too high, which may seriously cause the tire to explode, and also pose a great threat to people's safety.
