Novel stair structure

Abstract

The invention discloses a novel stair structure. The novel stair structure comprises a main staircase and a movable groove formed in the fixed end of the main staircase, wherein the main staircase iscomposed of multiple fixed steps which rise gradually and are integrally formed, an auxiliary staircase is composed of multiple movable steps which rise gradually and are fixedly connected, and a rotator is installed at the bottom end of the movable groove; and the movable groove is rotationally connected with the auxiliary staircase through the rotator, an oil hydraulic cylinder is rotationally installed on the inner wall of the upper end of the movable groove, and the telescopic end of the oil hydraulic cylinder is rotationally connected with the auxiliary staircase. The novel stair structure has the advantages that when the stair structure needs to be used, the telescopic end of the oil hydraulic cylinder completely retracts to drive the auxiliary staircase to rotate by a certain angle,a first inclined plane is parallel to a fourth inclined plane, and horizontal planes on the movable steps form stopping planes, so when a climber gets tired during climbing, the climber can temporarily put a suitcase on any horizontal plane; and compared with a plane on the side of a traditional staircase in the prior art, random sliding is prevented, and the auxiliary staircase, like the main staircase, can be used for climbing.

Description

technical field [0001] The invention relates to the technical field of stairs, in particular to a novel staircase structure. Background technique [0002] In schools, old residential areas and public buildings with few floors and low building height, direct elevators or escalators are generally not installed. Most of the stairs are integrally formed with a ladder structure. In the process of climbing the stairs, it is necessary to constantly move the suitcase, which requires a lot of physical strength, which is very difficult for the old, young, pregnant and women. [0003] To solve the above problems, we propose a novel staircase structure. Contents of the invention [0004] The purpose of the present invention is to solve the problems in the background technology, and propose a novel staircase structure. [0005] In order to achieve the above object, the present invention adopts the following technical solution: a novel staircase structure, including a main staircase a...
