Detailed Description

In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.

Referring to fig. 1, a portable double-sided ladder comprises two ladder frames 1, a stay bar 2 arranged on the ladder frame 1 and a pedal assembly arranged at one end of the ladder frame 1. The ladder frame 1 is divided into three parts equally, the ladder frames 1 of the adjacent parts are hinged with each other, the rotation angle of the ladder frame 1 after the hinge joint is 180 degrees, the ladder frames 1 of the adjacent parts are unfolded after rotating, or are in a vertical state or are in a folding state, namely the ladder frames 1 of the adjacent parts rotate 180 degrees in one direction, and the portable double-side ladder is folded after the ladder frames 1 of the adjacent parts rotate 180 degrees in the opposite direction. The footboard subassembly includes footboard 3 and two backup pads 4, and two backup pads 4 can set up footboard 3 on different frames with overturning respectively, and the rotation angle of backup pad 4 is 180, and the backup pad 4 upset back, or the lid fits footboard 3 or with footboard 3 level, and backup pad 4 rotates 180 back towards a direction promptly, and backup pad 4 docks with the side of footboard 3, and backup pad 4 rotates 180 back towards opposite direction, and the top surface of backup pad 4 covers each other with the top surface of footboard 3 and closes.

The use principle is as follows:

when the folding ladder is carried, the ladder frames 1 of the adjacent parts are mutually folded through the hinge structures, and when the folding ladder is used, the ladder frames 1 of the adjacent parts are mutually unfolded through the hinge structures; through unfolding the supporting plate 4, the supporting plate 4 and the pedal 3 are horizontal, the area of the pedal 3 can be increased, and people can stand on the pedal 3 more stably.

Referring to fig. 1, the technical solution further includes a first fixing member for unfolding and locking the ladder frames 1 of the adjacent sections, and the first fixing member includes a bolt 5 and a limiting groove 6. The bolt 5 is arranged on the surface of the ladder frame 1 in a sliding way, the limiting groove 6 is arranged on the surface of the ladder frame 1 of the adjacent part, and the bolt 5 is embedded into the limiting groove 6 or separated from the limiting groove 6 in a sliding way. By adopting the technical scheme, after the ladder frame 1 is unfolded, the bolt 5 is slid, the bolt 5 is embedded into the limiting groove 6, and the unfolded ladder frame 1 is fixed, so that the stability of the portable double-sided ladder is improved when the portable double-sided ladder is used.

Referring to fig. 1 and 2, the technical solution further includes a second fixing member for folding and locking the ladder frame 1 of the adjacent portion, the second fixing member includes an L-shaped buckle 7 and a rotating shaft 8, the L-shaped buckle 7 is rotatably disposed in the folding surface of the ladder frame 1 of the adjacent portion through the rotating shaft 8, a clamping groove 9 is disposed on the folding surface of the ladder frame 1 provided with the adjacent portion of the L-shaped buckle 7, and the rotating shaft 8 drives the L-shaped buckle 7 to be clamped in the clamping groove 9 or separated from the clamping groove 9. By adopting the technical scheme, after the ladder frame 1 is folded, the rotating shaft 8 is rotated to enable the L-shaped buckle 7 to be clamped in the clamping groove 9, and the folded ladder frame 1 is fixed, so that the portable double-sided ladder is prevented from being unfolded when being carried.

Referring to fig. 1, the supporting plate 4 of the present technical solution is provided with a supporting shaft 10, the stay bar 2 is provided with a groove, one end of the supporting shaft 10 is provided with the supporting plate 4, and when the supporting plate 4 is horizontal to the pedal 3, the other end of the supporting shaft 10 extends into the groove. By adopting the technical scheme, the bearing capacity of the supporting plate 4 can be improved. In order to facilitate the storage of the support shaft 10, the support plate 4 is provided with an accommodating groove for placing the support shaft 10, and one end of the support shaft 10 is hinged to the accommodating groove.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent changes made by using the contents of the present specification and the drawings, or applied directly or indirectly to the related technical fields, are included in the scope of the present invention.
