The invention relates to the technical field of elevators, in particular to an intelligent locking device of an elevator landing door lock, which comprises a lock hook, a base and an unlocking mechanism are arranged below an elevator door where the lock hook is located, a connecting cylinder is arranged at the top of the unlocking mechanism, and a buffer mechanism is arranged in the connecting cylinder. The anti-theft lock is provided with the unlocking mechanism, a maintainer inserts a triangular key into a triangular lock cylinder to jack up an ejector rod, the ejector rod jacks up a lock hook to achieve unlocking, through the arrangement of an eccentric wheel and a cylindrical sliding block, the maintainer can jack up the ejector rod to achieve unlocking when the maintainer cannot rotate clockwise or anticlockwise, and unlocking convenience is improved; according to the landing door lock, the ejector rod can be rapidly and automatically reset through the recovery deformation force of the reset spring, the safety of the landing door lock is improved, through the arrangement of the buffer mechanism, when the ejector rod makes contact with the landing door lock, the buffer mechanism buffers the impact force, and therefore the impact force on the door lock is reduced, and the service life of the landing door lock is prolonged.

    本发明涉及电梯技术领域,具体为一种电梯层门锁的智能止锁装置,包括:锁钩,所述锁钩所在的电梯门下方设有基座和解锁机构,所述解锁机构的顶部设有连接筒,所述连接筒内设有缓冲机构。本发明安装有解锁机构的设置,维保人员使用三角钥匙插入三角锁芯内,顶起顶杆,顶杆顶起锁钩实现开锁,通过偏心轮与圆柱体滑块的设置,维保人员无法顺时针或逆时针转动,都可以顶起顶杆,实现开锁,提高了开锁的便捷性;通过复位弹簧的恢复形变力,可使顶杆快速的自动复位,提高了层门门锁的安全性,本发明通过缓冲机构的设置,顶杆与层门门锁接触时,缓冲机构对撞击力进行缓冲,从而减少了对门锁的冲击力,提高了层门门锁的使用寿命。
