The invention relates to the technical field of intelligent security and protection, and discloses an automatic locking device for an elevator door. The automatic locking device comprises a support, alifting wheel is rotationally connected to the top of the support, a limiting wheel is fixedly connected to the surface of the right side of the lifting wheel, a power generation wheel is fixedly connected to the surface of the left side of the lifting wheel, a conductive wire is arranged on the surface of the power generation wheel, a permanent magnet is arranged on the outer side of the power generation wheel, a limiting rod is arranged on the lower side of the limiting wheel, and a spring is arranged on the surface of the limiting rod. According to the automatic locking device for the elevator door, the lifting wheel, the limiting wheel, the power generation wheel, the conductive wire, the permanent magnet, the limiting rod, the spring, a connecting rod, a control rod, a sliding way, asliding block, electromagnetic soft iron, a power shaft, a power rod and a matching rod are used in cooperation, and therefore the effects that when the lifting wheel rotates, the sliding block on the elevator door is automatically locked, and when the lifting wheel stops rotating, locking of the sliding block on the elevator door is automatically released, and meanwhile the limiting wheel on thelifting wheel is locked are achieved.

    本发明涉及智能化安防技术领域,且公开了一种电梯门的自动锁死装置,包括支架,所述支架的顶部转动连接有升降轮,所述升降轮的右侧表面固定连接有限制轮,所述升降轮的左侧表面固定连接有发电轮,所述发电轮的表面设置有导电线,所述发电轮的外侧设置有永磁体,所述限制轮的下侧设置有限制杆,所述限制杆的表面设置有弹簧。该电梯门的自动锁死装置,通过升降轮、限制轮、发电轮、导电线、永磁体、限制杆、弹簧、连杆、控制杆、滑道、滑块、电磁软铁、动力轴、动力杆和配合杆的配合使用,从而达到了在升降轮转动时自动锁死电梯门上的滑块,升降轮停止转动时自动解除电梯门上滑块的锁定,同时锁死升降轮上的限制轮的效果。
