新型逃生门锁装置技术分析与研发

Technical analysis and development of new type door lock device for escapes

分析消防锁的特点、功能和性价比,在已有防盗门锁具的基础上,对其门锁结构作了创新设计。提出了新型火灾逃生门锁装置的技术方案,以及解决快速开锁和防盗安全矛盾的措施。分析了主副锁机构的联动方式和锁体行程计算。该门锁装置并不改变原防盗锁的内部结构,而是增加一些移动副、转动副和平面连杆机构,在防盗门基础上改造锁具的安装方式,使正常开锁和逃生方式开锁溶为一体。该锁可广泛应用于学校和居民区等的房间门上,解决火灾地震等突发灾难时的迅速开门逃生问题。

By analyzing the features, function and cost per- formance of the fire-fighting lock, and on the basis of the door e- quipped with safe-guard door lock, an innovative design for its door lock structure was completed. It presents technical proposals of the new door locking device in fire escape device and measures of sol- ving unlocking quickly and conflict of safety and anti-theft. Also, it analyzes ways of linkage of master lock and second lock and com- putes the distance of buckle base. This locking device doesn ＂t change the inside designation of the former antitheft door while adding some institutions of hinges, motion kinematic pair and pla- nar linkage. On the basis of antitheft door, we change the lock in- stallcation to link unlocking normally and escaping ways. This lock can be used on doors of schools and residential area to resolve the problem of unlocking quickly when the fire is happening.
