[0018] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0019] Please refer to Figs. 1-3 A foldable ladder, including support frame 1, folding frame 2 and hinge 3, wherein one end of support frame 1 and one end of folding frame 2 are hinged through hinge 3.

[0020] It should be noted that the hinge 3 described in this embodiment adopts a thickened design and is connected between the support frame 1 and the folding frame 2 through high-strength bolts, which can bear a larger load. The other end of the folding frame 2 is fixedly connected with a protective frame 21 which adopts an integral arc-shaped structure and is provided with a buffer pad at the edge for protecting the safety of the ladder when it is close to the goods. The support frame 1 and the folding frame 2 are both provided with a plurality of trapezoidal platforms which are firmly connected with the support frame 1 and the folding frame 2 through a welding process.

[0021] The support frame 1 and the folding frame 2 are relatively folded through the hinge 3 in the folded state. After folding, the top of the support frame 1 is flush with the bottom of the folding frame 2, and the bottom of the support frame 1 is flush with the top of the folding frame 2.

[0022] It should be noted that in the folded state, the overall height of the ladder is greatly reduced, which is convenient for storage and transportation. In order to ensure the stability of the folded ladder, the support frame 1 and the folding frame 2 are provided with a buckle structure at the hinge 3 connection. The buckle structure can lock the folded state to prevent accidental unfolding.

[0023] The trapezoidal platforms are fixedly installed on the support frame 1 and the folding frame 2, and the surface of the trapezoidal platform is provided with anti-skid lines.

[0024] It should be noted that the anti-skid lines described in this embodiment adopt a cross-protruding design, which can provide strong anti-skid performance and ensure the grip of the feet even in a wet environment. The trapezoidal platforms are made of wear-resistant composite materials and can be used for a long time without aging. Each trapezoidal platform is provided with an edge baffle around it to avoid damage to personnel or goods caused by sliding objects during work.

[0025] The support frame 1 and the folding frame 2 are both made of high-strength aluminum alloy and are coated with a corrosion-resistant protective layer on the surface.

[0026] It should be noted that the aluminum alloy material described in this embodiment selects aviation-grade aluminum material, which provides higher strength while ensuring the lightweight of the ladder. The corrosion-resistant protective layer adopts a multi-layer anodizing process, which can effectively resist rainwater, oil stains and chemical corrosion, and is suitable for complex environments such as logistics and warehousing.

[0027] The support frame 1 and the folding frame 2 are kept in an unfolded state by a limiting piece which is a detachable connecting rod arranged between the support frame 1 and the folding frame 2.

[0028] It should be noted that the limiting piece described in this embodiment is connected with the support frame 1 and the folding frame 2 through a hinged structure at both ends. When unfolded, the connecting rod can support the overall weight of the ladder and limit its inclination angle. The connecting rod adopts a quick-release design, and the user can quickly separate the limiting piece by pressing the button, which is convenient for folding and storing the ladder. Embodiment 1

[0029] In the unfolded state, the ladder forms a stable triangular structure through the support frame 1, the folding frame 2 and the limiting piece, ensuring that it does not shake during use, and the ladder-shaped platform provides the standing space required for work, and the anti-skid pattern and the edge baffle improve the safety during work. In the logistics distribution scene, the staff can use the ladder to take and place high-position goods, and the protective frame 21 can prevent the goods from directly colliding with the ladder structure, protecting the safety of the goods and equipment. Embodiment 2

[0030] In the folded state, the support frame 1 and the folding frame 2 are folded relative to each other through the hinge 3, and the buckle structure locks the folding state of the ladder. At this time, the overall height and the occupied space of the ladder are significantly reduced, facilitating movement and storage in the warehouse scene. The folding design of the ladder also enables it to be used as a chair during leisure time, providing a temporary resting space for employees and further improving the use experience.

[0031] Meanwhile, the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.

[0032] Working principle: the ladder is connected through the support frame 1, the folding frame 2 and the hinge 3, realizing the folding and unfolding functions of the ladder. In the unfolded state, the structure is kept stable through the limiting piece, and the high-strength requirement of the logistics distribution work is met through the ladder-shaped platform with anti-skid pattern and corrosion-resistant aluminum alloy material. In the folded state, the buckle structure and the folding design significantly reduce the occupied space of the ladder, and at the same time provide a temporary resting function for employees, solving the problem of the bulky, inconvenient to move and large occupied space of the ladder in the prior art, and providing multifunctionality, which can be used for loading and unloading goods and used as a chair after folding, effectively improving the work safety and the convenience of employees.
