Abstract

The invention relates to an accessory for automobiles, in particular to an universal anti-explosive safe air cock for automobile tyres, which comprises an air cock body threaded with former air cock drum, a partition board in the air cock body, an air cock cap with a vent hole, an air-pressing bowl with a pipe, an air-pressing rubber ring in the air-pressing bowl with a pipe, a pressure rod passing through the partition board and the air-pressing bowl with a pipe, a compression spring disc integrated with the pressure rod, an air-charging spring located between the compression spring disc and the partition board, an air-pressing spring located between the air-pressing bowl with a pipe and the partition board, an ejector pin at the lower part in the air cock body, a seal ring at the joining site between the air cock body and the opening of the former air cock drum, an air-sealing bowl connected with the lower end of the pressure rod, and an air-sealing rubber ring adhered in the circular groove in the upper surface of the air-sealing bowl. 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 in existing tyres.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a general explosion-proof 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, ...
