[0097] The working principle of the present invention is as follows:

[0098] The staircase components are arranged vertically in sequence against the rear wall of the shell 501, and the side bar components of the staircase components are opposite to each other in sequence. The side bar components of the staircase components on the lowest layer are opposite to the shell mechanism 5, and the hanging platform 506 is pushed up along the hanging rod 504 to make it fit the crossbeam 502. The second push rod 509 extends from the third rail groove 503 and is inserted into the rotating rod 106 of the side bar component thereon, and the first push rod 110 inserted in the rotating rod 106 is pushed up, so that the first push rod 110 of the side bar component of the staircase component is pushed up in sequence and inserted into the rotating rod 106 thereon, and the motor is started. 507 rotates, and the second pulleys 510 on both sides rotate synchronously through the belt 511, thereby driving the rotating rod 106 in the side bar assembly to rotate, thereby adjusting the plug block 402 screwed to the rotating rod 106, that is, the sliding trolley 401 slides along the slot 103 to a suitable position, and through the connection of the connecting rod 404, the second sliding rod 304 of the stepping mechanism 3 is driven to slide along the turning rail 201 to a suitable position, so that the vertical plate mechanism 1 and the stepping mechanism 3 can be spliced ​​at different angles to adapt to different usage conditions and improve the scope of application.

[0099] Through the design of the adjustment component, the control components on both sides can be adjusted synchronously to uniformly drive the stepping mechanism 3 to adjust the angle, thereby improving the convenience of adjustment.

[0100] When the power mechanism 4 is used to slide along the steering mechanism 2 to adjust the splicing angle of the stepping mechanism 3 and the upright mechanism 1, the connecting rod 404 forms a side connection on the outside, so that the upright mechanism 1, the stepping mechanism 3 and the connecting rod 404 form a triangular stable shape, thereby improving the stability of the splicing of the upright mechanism 1 and the stepping mechanism 3.

[0101] Through the design of the limiting assembly, in the idle state, the second slide bar 304 of the stepping mechanism 3 is inserted into the steering rail 201 and abutted by the roller 205, so that the roller 205 is stably inserted at the corner of the steering rail 201. When the sliding trolley 401 slides downward along the slot 103, the second slide bar 304 can slide along the downward section of the steering rail 201 through the connection of the connecting rod 404. The second slide bar 304 is limited at the corner of the steering rail 201 by the limiting assembly to make it fit the steering rail 201, thereby reducing the instability of the sliding of the second slide bar 304 and improving the smoothness of the operation of the stepping mechanism 3 driven by the control assembly.

[0102] By setting the foot plate 308 on the stepping mechanism 3 with the spring shaft 309 as the axis deflection angle, the stepping mechanism 3 can be spliced ​​with the vertical plate mechanism 1 in an oblique manner through the adjustment of the control assembly. At this time, the height interval between the stepping mechanism 3 and the vertical plate mechanism 1 is small, which is convenient for using the staircase assembly to carry goods and improves the convenience of use;

[0103] People transporting goods can move along the side of the step 301 with the footboard groove 306, and their feet can be placed on the footboard 308. The deflection of the footboard 308 can make it safer for people to go up, thereby improving the safety of use.

[0104] The upper and lower arranged stair assemblies are connected by the first rail groove 105 and the slide rail 208 to form a unified whole. The vertical plate 101 of the uppermost stair assembly is fixedly connected to the shell 501, and the lowermost stair assembly is overlapped by the support plate assembly. After the splicing angle of the vertical plate mechanism 1 and the step mechanism 3 is uniformly adjusted by the adjustment assembly, the support plate assembly can be pulled outward first. When the support plate 512 is blocked by the holder 209 of the lowermost stair assembly, the lowermost stair assembly can be continuously pulled outward to form a step shape for people to use. When space is needed, the stair assemblies can be pushed into the shell 501 one by one and placed. By moving the stair assemblies, the occupied space can be changed at will, thereby improving the flexibility of use.

[0105] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
