Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] The general explosion-proof valve core of automobile tires includes: core rod 1, propulsion screw body 2, core rod sleeve 3, anti-exhaust sealing ring 4, exhaust pipe 5, combined sealing ring 6, anti-exhaust spring 7, anti-inflation sealing ring 8, Annular rubber ring bowl 9, anti-inflation spring 10 and air nozzle cap 11 with holes.

[0028] The core rod 1 is in the core rod sleeve 3, the core rod sleeve 3 is in the exhaust pipe 5, the upper end of the exhaust pipe 5 is connected with the lower end of the propulsion screw 2 in the form of buckle, and the anti-exhaust sealing ring 4 is stuck on the core rod sleeve 3 The lower surface of the port edge, combined with the sealing ring 6, is placed in the annular groove in the middle of the exhaust pipe 5, and the anti-exhaust spring 7 is placed on the core rod sleeve 3, which is located at the botto...

Abstract

The invention relates to an accessory for automobiles, in particular to an universal anti-explosive valve inside for automobile tyres, which comprises a rod, a propelling spiral, a rod sleeve, an anti-air-exhaust seal ring, an air exhaust pipe, a joining seal ring, an anti-air-exhaust spring, an anti-air-charging seal ring, a circular rubber bowl, an anti-air-charging spring and an air cock cap with a hole. The rod is in the rod sleeve, which is in the exhaust pipe; the anti-air-exhaust seal ring is adhered to the lower surface of the edge at upper end of the rod sleeve, the anti-air-exhaust spring is looped on the rod sleeve; the anti-air-charging spring is looped on the rod sleeve; the bottom end of the rod sleeve has a circular conical surface, the lower part of the rod sleeve has a clasp; at the upper port of the exhaust pipe, a circular conic surface is provided. At using, the valve inside of the former air cock is screwed out, and the valve inside of this invention is screwed in. The invention can both charge air and automatically discharge air so as to reduce pressure, and can allow non-professional technical persons to use on existing tyres. The invention is highly universal.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a universal anti-explosion valve core 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. This solution is only suitable for use when the tire factory makes new tires, and is difficult to apply to existing tires in 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. Though this scheme can be used on existing car tire, when inflating at every turn, exhaust valve must be unscrewed, and after inflation is finished, this valve must be unscrewed again, has increased inconvenience to...
