The invention discloses a lock hook assembly and an elevator landing door lock device. Wherein the lock hook assembly comprises a lock hook piece, a lock bottom plate, a door ball and a limiting rod, and a lock hook, a limiting fixing plate and a door ball mounting seat are arranged on the lock hook piece; the limiting fixing plate is rotationally fixed to the lock bottom plate through a rotating shaft so that the lock hook piece can be rotationally fixed to the lock bottom plate. The door ball is mounted and fixed on the door ball mounting seat through a door ball shaft; the limiting rod is arranged on the lock bottom plate; the knife arm of the door knife assembly drives the lock hook piece to rotate by extruding the door ball so that the lock hook can be opened to achieve unlocking, and the limiting rod is used for limiting the knife arm so that the door knife assembly and the lock bottom plate can be kept relatively fixed. According to the technical scheme, only one door ball is arranged on the lock hook assembly, the purpose that the door knife assembly and the lock bottom plate are relatively fixed is achieved through the limiting rod, therefore, the effective unlocking space required by the lock hook assembly is relatively reduced, the length of a door knife arm of the side door knife assembly of the elevator car door is further saved, and therefore the occupied space is reduced; the cost is reduced.
本发明公开一种锁钩组件及电梯层门锁装置。其中,锁钩组件包括锁钩件、锁底板、门球及限位杆,锁钩件上设置有锁钩、限位固定板及门球安装座;限位固定板通过一旋转轴旋转固定于锁底板以使锁钩件旋转固定于锁底板;门球通过一门球轴安装固定于门球安装座;限位杆设置于锁底板;门刀组件的刀臂通过挤压门球带动锁钩件旋转以使锁钩打开实现解锁,限位杆用以限制刀臂以使门刀组件与锁底板保持相对固定。本发明技术方案锁钩组件上仅设置一个门球,门刀组件与锁底板实现相对固定的目的由限位杆实现,因此本申请锁钩组件所要求的有效解锁空间将相对减小,进一步节省电梯轿门侧门刀组件的门刀刀臂的长度,从而减小占用空间,降低成本。
