Abstract

The invention relates to an accessory for automobiles, in particular to an universal anti-explosive pressure-limiting air cock for automobile tyres, which comprises a pressure rod, an air-charging spring, a partition board, an air pressing spring, an air pressing bowl, an air cock body, an air-sealing rubber ring, an air-passing hole, an air-sealing bowl, an ejector pin, an joining seal ring, an vent hole, a compression spring leaf and an air cock cap. An air-passing hole is provided in the air cock body, the air pressing bowl is located above the air-passing hole; the air-sealing bowl is located in the air-passing hole; the partition board is located in and threaded with the air cock body, the ejector pin is located in the lower end of the air cock body; the air-charging spring is located between the compression spring leaf and the partition board; the air pressing spring is located between the partition board and the air pressing bowl; both the upper edge of the air-passing hole and that of the air-sealing bowl have a conic lobe. The invention can both charge air and automatically discharge air so as to reduce pressure, and non-professional technical persons can easily add 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 general explosion-proof pressure-limiting air nozzle 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...
