The invention discloses an anti-drop connecting piece of elevator door plate. The anti-drop connecting piece comprises a threshold, the threshold is provided with a door plate sliding along the threshold, the lower end of the door plate is provided with a double-thread screw, a threshold groove is formed in the upper end of the threshold, the double-thread screw slides along the threshold groove, and the double-thread screw is further provided with an adjusting limiting piece. The adjusting limiting piece comprises a limiting ring arranged on the double-thread screw in a sleeving mode, two metal sheets are arranged at the lower end of the limiting ring, and after the lower end of the double-thread screw is screwed into an adjusting nut, metal sheets are opened. According to the anti-drop connecting piece of the elevator door plate, the opening and closing angle of the metal sheets at the lower end of the limiting ring can be adjusted through the screwing-in length of the adjusting nut on the double-thread screw, a sleeve is opposite to a guide groove of the threshold groove in position, it is guaranteed that the guide groove does not make contact with the double-thread screw but makes contact with the rotatable sleeve in the sliding process of the door plate, sliding contact is changed into rolling contact, the whole assembly can be prevented from being separated from the threshold groove through the opened metal sheets, and the anti-drop connecting piece of the elevator door plates is low in cost and convenient to install.

    本发明公开了一种电梯门板的防脱连接件,包括门槛,所述门槛上设置有沿其滑动的门板,所述门板下端设置有双头螺杆,所述门槛上端形成门槛槽,所述双头螺杆沿门槛槽滑动,所述双头螺杆上还设置有调节限位件。所述调节限位件包括套在双头螺杆上的限位环,所述限位环下端设置有两个金属片,双头螺杆下端拧入调节螺母后,金属片打开。本发明通过双头螺杆上的调节螺母的拧入长度能够调整限位环下端金属片的开合角度,通过套筒与门槛槽的导槽位置相对,在门板滑动过程中保证导槽不与双头螺栓接触而是与能够转动的套筒接触,变滑动接触为滚动接触,通过打开的金属片能够避免整体组件从门槛槽中脱离,本发明成本低,安装方便。
