[0002] A ladder, an everyday tool, consists of two long, thick rods with a crossbar running through the middle for climbing. Aluminum alloy ladders are made of high-strength aluminum alloy, characterized by their light weight and high strength. They greatly reduce the workload for construction workers. Currently, there are many manufacturers of aluminum alloy ladders nationwide. Since the quality of a ladder is directly related to personal safety, it is essential to purchase from reputable and established companies.

[0003] The description of a novel combined frame safety ladder cage in the prior art (publication number CN206860074U) mentions that "a vertical diagonal bar is fixed on the upright, and the upright is connected to the horizontal bar by bolts. A horizontal steel tread of the ladder is fixed on the horizontal steel tread of the ladder. A ladder beam is fixed on the horizontal steel tread of the ladder, and a ladder guardrail is installed on the ladder beam." However, the outer side of the ladder cage in the prior art lacks a protective structure, and there is also a lack of support structure for the inclined surface of the stair tread, so it may not be safe and stable to use.

A stair tread is installed inside the outer frame, and multiple sets of support frames are fixed to the lower end of the stair tread. The lower end of each support frame is vertically fixed to a corresponding set of pressure plates below, and the pressure plates are fixed between the left and right parallel support columns.

[0006] Furthermore, the outer frame adopts a rectangular frame structure, and the outer frame is fixedly connected to the outer frame by welding.

[0007] Furthermore, a protective mesh is provided inside the outer frame, and the protective mesh is made of stainless steel mesh.

[0008] Furthermore, the lower end of the support column is fixed with a support leg, which is made of cast steel and has multiple sets of screw holes.

[0009] Furthermore, the upper surface of the stair tread is provided with multiple sets of steps, and the lower surface of each set of steps is fixed with multiple sets of support legs, and the lower ends of the support legs are fixed to the stair tread.

[0010] Furthermore, the support frame fixed to the lower end face of the stair tread adopts a rectangular arch structure, and the lower end of the support frame is vertically welded to the pressure plate.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The outer frame and the inner protective net of this utility model are designed to provide comprehensive protection for the user's safety by covering the entire ladder cage frame with a mesh cover. The installation and fixing method is simple and stable, and the use is safe and reliable.

[0013] 2. The outer frame of this utility model adopts four sets of support columns as the main support structure, and the bottom of the support columns is fixed with feet to ensure the stability of the placement, making it safer and more stable to use.

[0014] 3. The supporting feet and stair treads of this utility model are designed to provide a step structure that is neat, gentle, and stable, ensuring safe and reliable use. It can be used by multiple people at the same time and is safer and more durable.

[0015] 4. This utility model uses a support frame and pressure plate to reinforce the lower end of the stair tread, which helps to increase the stability of the stair tread installation and make it last longer. Attached Figure Description
