Abstract

The utility model discloses a staircase. The staircase comprises multiple steps, wherein an angle formed between a first surface and a second surface of each step is greater than or equal to 90 degrees; each step is divided into a first portion and a second portion based on a plane where the connecting line of the central points of the two sides of the first surface and the connecting line of the central points of the two sides of the second surface are; the first portion and the second portion of each step are rotationally connected, and a rotating point is located at the central point of the first surface; a first connecting rod is arranged at one side face of each step and is hinged to each first portion; a motor is arranged on one side face of each step, a second connecting rod is arranged on the output shaft of the motor in a bending manner, a waist hole is formed in the second connecting rod, and one end of the first connecting rod is connected in a sliding manner in the waist hole. The staircase is generally a stair convenient for people to walk; the motor rotates to drive the first portions to turn over so as to change the staircase into a sliding board when a heavy object needs to be conveyed, so that people can place the heavy object on a cart and carry the heavy object upstairs along the sliding board easily by using the cart.

Description

technical field [0001] The invention relates to a staircase, in particular to a staircase capable of realizing the transformation between a slide and a ladder. Background technique [0002] In daily life, people's general families generally adopt steps when building stairs, because the steps are convenient for people to walk. But when heavy objects are to be carried, the stepped stairs cannot be carried by carts, and must be carried by manpower, and it is quite laborious in the process of carrying. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a staircase, which can realize the conversion between slides and stairs, so that the staircase is generally a staircase, and can be converted into a slide when heavy objects need to be carried, so that the heavy objects can be installed on the push Push on the car for easy handling. [0004] In order to solve the above-mentioned technical problems, the present inventi...
