Abstract

The invention relates to an accessory for automobiles, in particular to an universal anti-explosive safe air cock for automobile tyres, which comprises a pressure rod, an air cock body, a spring, an air-pressing bowl, an air-sealing rubber ring, an air discharging hole, an air charging hole, an air-charging seal ring, a joining seal ring, an air-sealing bowl, an ejector pin and an air cock cap. The air cock body is threaded with the former air cock drum, the pressure rod passes through the through hole in the air-pressing bowl and the air charging hole in the air cock body, the lower end of the pressure rod is connected with the air-sealing bowl, the spring is looped on the pressure rod; the ejector pin is located inside the lower end of the air cock body. The upper end of the ejector rod is a flat cylinder, the air discharging hole is an arc-like hole with two arcs that are same and co-central; in the upper surface separated in the air cock body, two conic lobes that are of same arc and co-central with the outer and inner arc of the air discharging hole are provided. The invention can both charge air and automatically discharge air so as to reduce pressure, and non-professional technical persons can easily use the invention for the air cocks of existing tyres.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a universal non-explosion safety valve for automobile tires. Background technique [0002] Car tire blowouts caused by high temperature and overloading have become a prominent traffic problem. At present, the existing technologies to solve this problem through automatic exhaust and decompression can be roughly divided into the following three categories: [0003] 1. Add an exhaust valve on the wheel. When the air pressure in the tire is too high, the valve will automatically open to release the air and reduce pressure. For example the patent No. is 02210731.2 " tire explosion-proof device ", this scheme is only suitable for adopting when tire factory makes new tire, is difficult to be applicable to the tire in existing use. [0004] 2. After the inflation is completed, screw an exhaust valve on the original air nozzle of the tire to automatically exhaust and decompress. For example, ...
