Stair with automatic lifting steps

Abstract

The invention discloses a stair with automatic lifting steps. The stair comprises supporting rods, a mounting frame and the steps; the supporting rods are symmetrically distributed on the two sides ofthe mounting frame, and a first opening is formed in the vertical face of the mounting frame; the steps vertically move in the first opening, and a lead screw and a guide rod are arranged in the first opening; the upper end and the lower end of the lead screw are rotationally connected with the horizontal face of the mounting frame; bosses are arranged on the steps and internally provided with threaded holes; the lower end of the lead screw and the bosses are connected through threads; the lower end of the guide rod and the steps are slidably connected; a motor is arranged on the supporting rod at the front end, and the output end of the motor is provided with a first bevel gear; the lower end of the lead screw is provided with a second bevel gear, and the first bevel gear and the secondbevel gear are engaged; and a pressure sensor is arranged between the steps and the horizontal face of the mounting frame. The disabled and people inconvenient to walk only need to stand on the stepsto walk forwards continuously, then the stair climbing process can be completed, the stair climbing problem is solved, the difficulty of stair climbing is reduced, and practicability is good.

Description

[0001] The invention relates to the technical field of stairs, in particular to a staircase with automatically ascending and descending steps. Background technique

[0002] Stairs are components used as vertical traffic between floors in buildings, and are mainly used for traffic connections between floors and when the height difference is large. Stairs should also be provided in multi-storey and high-rise buildings with elevators and escalators as the main vertical means of transportation. Although elevators are used as the main vertical means of transportation in high-rise buildings, stairs are still reserved for escape in case of fire.

[0003] The existing stairs are all made of reinforced concrete. Climbing stairs is a great burden for people with physical disabilities and walking difficulties. It is difficult to climb stairs and takes a long time. If you stand unstable, you will easily fall from the stairs. , there is a greater security risk. Conten...
