Abstract

The invention relates to an accessory for automobiles, in particular to an universal anti-explosive air cock for automobile tyres, which comprises an air cock drum and a rubber casing of a former air cock, an additive air cock threaded with a former air cock drum, an air cock cap with a vent connected with the additive air cock, a seal ring in the additive air cock, an exhaust seal ring at the upper part of the seal ring, a joining seal ring at the lower surface of the seal ring, a rod sleeve in an air-sealing ring, an anti-air-exhaust spring looped on the rod sleeve, a pressure rod in the rod sleeve, a rod cap welded with the top end of the pressure rod, an air-sealing bowl located at middle of the pressure rod and integrated with the pressure rod, an anti-air-charging spring below the air-sealing bowl, an air-charging ring adhered in the air-sealing bowl and a pressure-adjusting nut looped on the rod sleeve. The invention can both charge air and automatically discharge air so as to reduce pressure, and can allow non-professional technical persons to rebuild existing air cocks. The invention is highly universal.

Description

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