The invention discloses an elevator limit switch which comprises an elevator limit switch body, a rotating shaft is movably installed in the elevator limit switch body, a first connecting plate is installed on one side of the rotating shaft, and a mounting groove is formed in the top of the first connecting plate. A first reset spring is mounted at the top of the first connecting plate through a mounting groove, the top end of the first reset spring is fixed to the inner wall of the top of the elevator limiting switch body, a second connecting plate is mounted on the other side of the rotating shaft, and fixed threaded rods are symmetrically mounted at the top of the second connecting plate in a threaded penetrating mode; and a second reset spring is mounted at the bottom of the second connecting plate through a fixed threaded rod. The first reset spring and the second reset spring are stretched to generate reverse elastic potential energy, so that the elevator limit switch body can stably and quickly rebound to the original position without being subjected to pressure, and the situation that the rebound of the elevator limit switch body is affected due to the fact that the connecting spring is damaged is prevented.
本发明公开了一种电梯限位开关,包括电梯限位开关本体,所述电梯限位开关本体的内部活动安装有转动轴,所述转动轴的一侧安装有第一连接板,所述第一连接板的顶部开设有安装槽,所述第一连接板的顶部通过安装槽安装有第一复位弹簧,且第一复位弹簧的顶端固定在电梯限位开关本体的顶部内壁上,所述转动轴的另一侧安装有第二连接板,所述第二连接板的顶部对称螺纹贯穿安装有固定螺纹杆,所述第二连接板的底部通过固定螺纹杆安装有第二复位弹簧。本发明通过第一复位弹簧和第二复位弹簧被拉伸产生反向弹性势能,使该电梯限位开关本体在不受到压力的作用下,能够稳定快速的回弹到原来的位置,防止连接弹簧损坏,而影响该电梯限位开关本体的回弹。
