A fireproof lock comprises a lock body, a handle assembly and a lock cylinder assembly, wherein the lock body, the handle assembly and the lock cylinder assembly are arranged on a door plate; the handle assembly comprises a square shaft; the lock cylinder assembly comprises a back locking rotary rod; and the square shaft and the back locking rotary rod are wrapped with graphite fireproof sealing sleeves. The graphite fireproof sealing sleeves are arranged on the square shaft and the back locking rotary rod in a sleeving mode, so the graphite fireproof sealing sleeves can be prevented from falling off from the lock due to frequent collision of the door plate, graphite materials are prevented from leaking, and then the fireproof effect of the fireproof lock can be improved. Through the arrangement of the graphite fireproof sealing sleeves and graphite fireproof sealing gaskets, the internal structure of the fireproof lock can be simplified, installation is convenient, consumption of thegraphite materials is reduced, and the cost is saved.
一种防火锁具，包括装设于门板上的锁体、把手组件和锁芯组件；所述把手组件包括方轴；所述锁芯组件包括反锁旋杆；所述方轴与反锁旋杆上包裹有石墨防火密封套；通过将石墨防火密封套套装在方轴以及反锁旋杆上，可以防止石墨防火密封套因门板频繁磕碰从锁具上脱落下来，防止石墨材料泄漏，进而可以提高本发明的防火效果；通过石墨防火密封套以及石墨防火密封垫的设置，可以简化防火锁具的内部结构，安装方便，减少石墨材料的消耗，节约成本。
