In the elevator sill connecting structure, the pulley is sleeved at the left end of the sliding rod, and the sliding rod is inserted on the connecting rod and fixed through the fastener.
In the elevator sill connecting structure, the open slot is located on the bottom surface of the sill body, and the pulley is transversely arranged.
In the elevator sill connecting structure, the sliding rod comprises a vertical rod part and a transverse rod part which are vertically crossed, the pulley is sleeved at the top end of the vertical rod part, the left end of the transverse rod part is connected with the bottom end of the vertical rod part, and the transverse rod part is inserted on the connecting rod and fixed through a fastener.
Compared with the prior art, the connecting rod of the elevator door is connected to the rear side or the bottom surface of the sill body in a sliding mode, the top surface of the sill body is a plane, dust and other impurities cannot enter the open slot of the sill body, and the failure rate is low.
