In order to achieve the purposes, the stair with the stable positioning structure comprises a mounting frame and a stair body, wherein the top end of the mounting frame is rotatably connected with a supporting plate, the supporting plate is connected with the swinging end of the mounting frame through two connecting rods, one end of each connecting rod is rotatably connected to the side wall of the supporting plate, the other end of each connecting rod is slidably inserted with a positioning rod, a plurality of positioning holes are formed in the side wall of the mounting frame, the aperture of each positioning hole is equal to the diameter of each positioning rod, a plurality of clamping blocks are fixedly connected to the upper end of the mounting frame, and a plurality of clamping grooves in sliding fit with the corresponding clamping blocks are formed in the lower surface of the stair body.
As a further preferred feature of the technical solution, two of the connecting rods are symmetrically distributed on two sides of the mounting frame.
As a further preferable mode of the technical scheme, the positioning rod is made of hard alloy.
As a further preferable aspect of the present invention, the plurality of positioning holes are distributed at equal intervals in a straight line.
As a further preferable mode of the technical scheme, the upper end of the clamping block is of a reverse hook type structure.
As a further preferable mode of the technical scheme, one end of the positioning rod is fixedly connected with a limiting block, the other end of the positioning rod is provided with external threads and is sleeved with a fixing nut, and the fixing nut is connected with the positioning rod through threaded fit with the external threads.
As a further preferable mode of the technical scheme, handles are fixedly connected to two sides of the upper end of the ladder body respectively.
The utility model provides a stair with a stable positioning structure, which has the following beneficial effects:
According to the utility model, a stable triangular structure is formed by the mounting frame, the supporting plate and the connecting rod, the clamping blocks on the upper surface of the mounting frame are embedded into the clamping grooves at the bottom of the ladder body, the ladder body can be fixed on the mounting frame, the mounting mode can ensure the firmness and realize quick disassembly and assembly, when the inclination angle of the ladder body needs to be regulated, the positioning rod can be pulled out of the positioning hole and replaced by inserting the positioning hole, and at the moment, the inclination angle of the mounting frame can be automatically changed, so that the inclination angle of the ladder body is changed.
