AI Technical Summary

Technical Problem

Existing tire valve cores are prone to wear and aging in terms of sealing performance, leading to air leakage, and the release method is limited, making it impossible to quickly reduce tire pressure.

Method used

A multifunctional tire valve core was designed, which adopts a double-layer sealing structure and a diversion tube structure, including components such as a first baffle plate, a second baffle plate, a core rod, a conical plug, a rod-shaped plug, and a diversion tube, to achieve double-layer sealing and multifunctional venting.

Benefits of technology

It improves the sealing performance of the valve core, provides dual venting methods, and ensures tire pressure stability and rapid decompression.

Abstract

本实用新型涉及气门芯技术领域,且公开了一种多功能轮胎气门芯,包括芯管,芯管内设第一阻板与第二阻板,中部竖向设置芯杆,芯杆底端依次连接锥形塞、限位杆及杆形塞,限位杆周侧设弹簧。打气时,芯杆受压下移,锥形塞与杆形塞分别脱离第一、第二阻板形成进气通道;打气完成,芯杆回弹,两者分别与阻板啮合形成双层密封,提升密封性。此外,芯管底部一侧设分流管,外壁开设有通孔,端口螺纹连接带限位塞的密封罩。胎压过高时,可通过转动密封罩使通孔漏气放气减压。本实用新型通过双层密封结构增强了气密性,同时提供两重放气排压方式,满足多样化使用需求,具备多功能性。
