Description

Technical Field

[0001] This utility model relates to a platform ladder using a nylon plastic platform. Background Technology

[0002] Most platform ladders on the market are currently made of metal or traditional engineering plastics. While metal platform ladders have high structural strength and load-bearing capacity, they are heavy, inconvenient to move, and prone to corrosion under long-term use or in humid environments, affecting their lifespan and appearance. To prevent rust, protective treatments such as spraying and electroplating are usually required, which not only increases manufacturing costs but also complicates the production process.

[0003] On the other hand, some platform ladders have attempted to use traditional engineering plastics to replace metal materials in order to solve corrosion problems and reduce weight. However, these engineering plastics generally suffer from insufficient mechanical properties, poor rigidity, and weak creep resistance. They are prone to deformation or structural damage when subjected to large working loads, making it difficult to meet stability and safety requirements.

[0004] In addition, the panel structure of traditional platform stairs is mostly assembled from metal profiles or plates by welding, bolting and other methods. The manufacturing process is complicated and the assembly efficiency is low, which is not conducive to large-scale production and integrated design. Utility Model Content

[0005] The purpose of this invention is to provide a lightweight, corrosion-resistant, and strong platform ladder made of nylon plastic.

[0006] The purpose of this utility model is achieved as follows: A platform ladder using a nylon plastic platform includes ladder feet and a nylon plastic platform. The ladder feet are respectively hinged to both ends of the nylon plastic platform. The nylon plastic platform includes a frame and a nylon plastic panel. The nylon plastic panel is provided with a handle and has drainage holes spaced apart. The frame surrounds the nylon plastic panel.

[0007] By using nylon plastic platforms in the platform ladder, a balance between lightweight design and high strength is achieved. The nylon plastic panels offer excellent corrosion resistance and impact resistance, effectively extending the ladder's lifespan and safety. Its integrated injection-molded structure reduces welding and bolting processes, significantly improving production efficiency. Handles on the panels facilitate handling and storage, enhancing portability. Spaced drainage outlets help drain water quickly, preventing water accumulation and keeping the platform surface dry and slip-resistant. The frame surrounding the panels forms a stable support structure, further improving overall load-bearing capacity and stability.

[0008] The objective of this utility model can also be achieved by the following technical measures: Furthermore, the bottom of the nylon plastic panel is provided with horizontal and vertical reinforcing ribs at intervals, and the drain outlet is equipped with a cross-shaped reinforcing rib. The horizontal, vertical, and cross-shaped reinforcing ribs are all made of nylon plastic, and the nylon plastic panel, horizontal, vertical, and cross-shaped reinforcing ribs are integrally injection molded.

[0009] By incorporating horizontal and vertical reinforcing ribs at the bottom of the nylon plastic panel and integrating cross-shaped reinforcing ribs into the drainage outlets, and by using a single injection molding process with the panel, the overall structural rigidity and fatigue strength of the platform can be significantly improved, preventing deformation or cracking under long-term loads. Simultaneously, the one-piece molding structure reduces assembly steps and connection points, improving production efficiency and structural reliability; it enhances load-bearing capacity while maintaining lightweight design, making the platform ladder more stable and safer during use, while also ensuring ease of use and durability.

[0010] Furthermore, the nylon plastic panel has openings on both sides near its center, and the handle is formed in the middle of the nylon plastic panel between the openings.

[0011] By creating openings on both sides of the center of the nylon plastic panel and forming a one-piece handle in the central structure between the two openings, the number of parts and assembly process are simplified, while effectively ensuring the overall structural strength and stress balance of the panel. The handle is integrally injection molded with the panel, avoiding stress concentration and loosening risks during later installation, thus improving overall reliability and durability. The handle also makes the platform ladder more convenient to transport, install, and store, significantly enhancing its usability.

[0012] Furthermore, the thickness at the connection between the transverse and vertical reinforcing ribs is greater than the thickness of either the transverse or vertical reinforcing rib.

[0013] By designing the connection between the horizontal and vertical reinforcing ribs to have a thickness greater than that of the horizontal or vertical reinforcing ribs themselves, a gradual wall thickness transition is created. This not only effectively avoids stress concentration but also improves the load-bearing capacity and impact resistance of the connection points. This design results in more uniform force distribution, significantly enhancing the overall structural strength and stability of the nylon plastic platform while maintaining good formability and material utilization, further improving the product's durability and reliability.

[0014] Furthermore, the nylon plastic platform is a biomass nylon reinforced plastic platform.

[0015] Using biomass-reinforced nylon plastic as the material for nylon plastic platforms allows them to maintain high strength, high toughness, and excellent heat resistance while achieving green environmental protection and sustainable manufacturing. This material is derived from renewable resources, significantly reducing dependence on petroleum-based feedstocks and decreasing carbon emissions. Simultaneously, the addition of reinforcing components such as glass fiber enhances the platform's flexural strength, impact resistance, and dimensional stability, ensuring excellent structural reliability even after long-term use. The application of this material not only meets mechanical performance requirements but also considers environmental protection and economic efficiency, aligning with current trends in energy conservation, emission reduction, and sustainable development.

[0016] Furthermore, the frame is a metal frame, and the ladder legs are hinged to the metal frame.

[0017] The metal frame structure gives the nylon plastic platform higher load-bearing capacity and structural stability, maintaining good strength and deformation resistance under heavy loads or frequent use. The metal frame provides robust hinge points for the ladder legs, ensuring smooth opening and closing and even stress distribution, thus improving the platform ladder's safety and durability. Simultaneously, the combination of the metal frame and plastic panels achieves a balance of rigidity and flexibility, ensuring structural strength while also achieving lightweight and corrosion resistance.

[0018] Furthermore, the nylon plastic platform is a polyamide plastic platform.

[0019] Using polyamide plastic as the platform material gives the platform excellent mechanical strength, toughness, and wear resistance, effectively resisting structural deformation caused by long-term loads and impacts. Polyamide plastic has good corrosion resistance and chemical stability, making it suitable for use in humid and watery environments, extending product lifespan; at the same time, its light weight and good formability allow for integrated manufacturing through injection molding, simplifying production processes and improving assembly precision, thereby enhancing the overall reliability and ease of use of the platform ladder.

[0020] The beneficial effects of this utility model are as follows: This invention achieves a harmonious balance between lightweight, corrosion resistance, and high strength by employing a nylon plastic platform. The nylon plastic panel structure incorporates handles and intermittent drainage outlets, facilitating handling and storage while also providing drainage and anti-slip functionality, thus enhancing the product's safety and convenience in outdoor or damp environments.

[0021] This utility model features horizontal and vertical reinforcing ribs arranged at the bottom of the nylon plastic panel, and a cross-shaped reinforcing rib added inside the drain outlet, which effectively improves the overall rigidity and fatigue strength of the platform and prevents deformation or breakage under long-term use; at the same time, the reinforcing ribs and the panel are integrally injection molded, avoiding stress concentration during assembly and improving overall reliability.

[0022] This invention further optimizes the mechanical transmission path by implementing a progressive wall thickness transition design at the connection between the transverse and vertical reinforcing ribs, enabling the nylon plastic platform to maintain structural stability and durability when bearing heavy loads.

[0023] This invention utilizes biomass-reinforced nylon plastic as the material for nylon plastic platforms, enabling them to maintain high strength, high toughness, and excellent heat resistance while achieving green environmental protection and sustainable manufacturing. This material is derived from renewable resources, significantly reducing dependence on petroleum-based feedstocks and decreasing carbon emissions. Simultaneously, the addition of reinforcing components such as glass fiber enhances the platform's flexural strength, impact resistance, and dimensional stability, ensuring excellent structural reliability even after long-term use. The application of this material not only meets mechanical performance requirements but also considers environmental protection and economic efficiency, aligning with current trends in energy conservation, emission reduction, and sustainable development.

[0024] This utility model features a nylon plastic platform with an external metal frame. The ladder legs are hinged to the metal frame, ensuring the overall load-bearing capacity and support strength. The combination of the metal frame and the nylon plastic panel forms a composite structure that combines rigidity and flexibility. This ensures structural stability while significantly reducing the overall weight of the machine, improving the product's portability and lifespan. Attached Figure Description
