SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a sill structure of layer door, its is rational in infrastructure, and can effectively reduce the running resistance of door slider to avoid influencing the life of door slider.
In order to achieve the purpose, the technical scheme of the utility model is to design a landing sill structure, which comprises a landing sill body and a door slider arranged inside the landing sill body;
the landing sill body comprises a top plate, a bottom plate and a side plate connected between the top plate and the bottom plate;
the bottom of the door sliding block is provided with a lower groove, an installation frame is arranged in the lower groove, a roller pin is rotatably installed in the installation frame, and the roller pin is contacted with the bottom plate; the top of the door slider is provided with two upper grooves, each upper groove is internally provided with a movable seat, a buffer spring is connected between the bottom of the movable seat and the bottom of the upper groove, the top of the movable seat is provided with a ball groove, balls are arranged in the ball grooves, the balls can roll in the ball grooves, and the balls protrude out of the groove openings of the ball grooves and contact with the top plate.
Preferably, the top of the bottom plate is provided with a guide groove, and the roller pin is partially embedded in the guide groove.
Preferably, a rotating shaft is fixedly arranged in the needle roller in a penetrating manner, and two ends of the rotating shaft are respectively and rotatably connected with two opposite side walls of the mounting frame.
Preferably, the mounting rack is of an inverted U-shaped structure.
Preferably, the top plate is provided with an opening, the top of the door slider is connected with a fixing plate, and the other end of the fixing plate penetrates through the opening and is connected with the elevator landing door.
Preferably, the two upper grooves are symmetrically arranged on two sides of the fixing plate.
Preferably, the bottom of the bottom plate is connected with a sill bracket.
The utility model has the advantages and the beneficial effects that: the utility model provides a sill structure of layer door, its is rational in infrastructure, and can effectively reduce the running resistance of a slider to avoid influencing the life of a slider.
Through set up kingpin and the ball with the contact of layer door sill body inner wall on the door slider, at the in-process that elevator layer door was opened or was closed, the friction between door slider and the layer door sill body is rolling friction, and consequently the frictional resistance when door slider moves is less for the operation of door slider is more smooth and easy, and is favorable to prolonging the life of door slider.
