An opening and closing mechanism comprises an inner cavity, the inner cavity is formed in an elevator door, a through groove is formed in the inner wall of the inner cavity, two arc plates are movably connected to the inner wall of the through groove through connecting assemblies, and the outer surfaces of the arc plates on the two sides are attached to each other; and the outer surface of the arc plate is in threaded connection with a screw rod, the outer surface of the screw rod is provided with a fixed bearing, the outer surface of the fixed bearing is fixedly connected with a fixed plate in a penetrating mode, and the outer surface of the fixed plate is fixedly connected with the inner wall of the sliding cavity. The problems that when an elevator fails, the elevator door continues to be closed due to the fact that induction cannot be conducted or induction is not conducted in time, passengers are prone to being hurt, meanwhile, due to locking of electrical elements, when the elevator fails, the elevator door is difficult to open, the rescue difficulty is increased, and the maintenance cost is increased due to the fact that the elevator door is pried open for rescue are solved.
本发明公开了一种垂直电梯用电梯门结构,所述开合机构包括内腔,所述内腔开设在梯门的内部,所述内腔的内壁开设有贯通的通槽,所述通槽的内壁通过连接组件活动连接有两个弧板,两侧所述弧板的外表面相互贴合,所述弧板的外表面螺纹连接有螺杆,所述螺杆的外表面设置有固定轴承,所述固定轴承的外表面贯穿固定连接有固定板,所述固定板的外表面与滑腔的内壁固定连接,涉及垂直电梯技术领域,解决了现有垂直电梯梯门在关闭行程末端,无法感应或者感应不及时,导致梯门继续关闭,从而容易对乘客造成伤害,同时由于电气元件的锁紧,导致电梯在失灵时,梯门较难打开导致营救难度增大,以及撬开梯门营救导致维修成本增大的问题。
