Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] The universal explosion-limiting pressure-limiting air nozzle for automobile tires consists of a pressure rod 1, a nozzle body 2, a nozzle cap 3, a slider 4, a housing 5, an air pressure bowl 6, a spring 7, an air pressure rubber ring 8, an air blocking rubber ring 9, and an air sealing bowl 10. It is composed of a sealing ring 11, a push rod 12, an exhaust hole 13, an exhaust side hole 14, an air inlet 15 and an air outlet 16.

[0031] Wherein, the housing 5 is cylindrical, and one end thereof is threadedly connected with the tire original air nozzle, and the other end is threadedly connected with the nozzle body 2 . There is a partition in the middle of the housing 5, and the air inlet 15 and the air outlet 16 are respectively located on the partition. The mouth body 2 is in a dynamic fit relationship with the pressure rod 1 , its lower part i...

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 cock body, an air cock cap, a slider, a casing, an air pressing bowl, a spring, an air-pressing rubber ring, an air-blocking rubber ring, an air-sealing bowl, an joining seal ring, an ejector pin, an air-discharging hole, an air-discharging edge hole, an air inlet and an air outlet. The casing is like a drum, one end of the casing is connected with the former air cock of a tyre, another end is connected with the air cock body. The lower part of the air cock body is connected with the casing, the upper part is connected with the air cock cap; the rod part of the air-sealing bowl is connected with the slider. The air-pressing bowl is located in the casing, the spring is compressed between the slider and the air-pressing bowl. The air-pressing rubber ring and the air-blocking rubber ring seal respectively the air inlet and outlet of the casing. The joining seal ring is adhered in between the edge of the former air cock and the circular lobe at lower part of the casing. The invention can be installed on an existing air cock, and can timely reduce the pressure in the tyre, stop any tyre explosion due to increased air pressure in the tyre.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a universal non-explosion-limiting 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 d...
