Tire safety inflation device

Abstract

The invention discloses a tire safety inflation device. The structure of the tire safety inflation device comprises an air suction pump, a transitional connecting piece, an inflation automatic alarming and stopping device, a push-and-pull handle, an inflation pipe connecting head, a compression air pump, movable casters and caster mounting bases; and the air suction pump is mounted on the upper surface of the compression air pump and connected to the compression air pump by using a welding mode. According to the tire safety inflation device, the internal pressure of a tire can be known and noted at any time while the tire is inflated so as to prevent the tire from being burst to injure working personnel because the tire is excessively inflated and the internal pressure of the tire is higher than atmospheric pressure; and moreover, after the inflation of the tire is finished, alarming and prompting can be made to inform the working personnel of closing inflation equipment in time so asto reduce energy waste; and moreover, gas blocked between an inflation pipeline and the compression air pump can be rapidly exhaust to the atmosphere in time so as to prevent causing pressure damage to the inflation pipeline.

Description

technical field [0001] The invention relates to the field of tire safety inflation, more precisely, a tire safety inflation device. Background technique [0002] Robert Thomson proposed to fill the elastic bag with compressed air to alleviate the vibration and impact during exercise. Although tires at the time were made of leather and rubberized canvas, such tires already showed the advantage of low rolling resistance. According to this principle, John Dunlop made a rubber hollow tire in 1888, and then Thomas made a rubber hollow tire with a valve switch. But, there is following shortcoming in this tire inflation equipment at present: [0003] 1. The control of the gas saturation inside the tire is not accurate, which makes the tire easy to over-inflate or under-inflate, which affects the use of the tire. [0004] 2. Inflating the tire continuously for a long time may easily cause the tire to explode due to excessive internal pressure and accidentally injure the staff. ...

AI Technical Summary

Problems solved by technology

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a tire safety inflation device to solve the inaccurate control of the gas saturation inside the tire in the prior art, resulting in the tire being easily over-inflated or under-inflated, affecting The use of tires and continuous inflation of the tires for a long time may easily cause the tires to explode due to excessive internal pressure and accidentally injure the staff.
