Description

Technical Field

[0001] This utility model relates to the field of trailer extended cargo platform technology, specifically a foldable trailer extended cargo platform structure. Background Technology

[0002] Semi-trailers are common road transport vehicles. When loading and unloading goods, they need to cooperate with the loading and unloading platform of the warehouse. However, when the semi-trailer is reversing into the warehouse or aligning with the loading and unloading platform, the tailgate is prone to hitting the edge of the platform, causing deformation of the tailgate or cracking of the platform edge, which affects the safety of subsequent loading. At the same time, when loading long, lightweight goods, the semi-trailer is limited by the length of the loading platform, and the goods need to be bent or cut, which affects the integrity and quality of the product. The goods cannot be loaded smoothly and completely, and the adaptability of the loading is poor. To solve the above problems, a foldable trailer extension platform structure is needed.

[0003] Existing trailer loading platforms cannot be folded and stored during operation. Their fixed dimensions limit the loading of long, lightweight goods, making it difficult to transport them completely. This results in poor cargo compatibility and a lack of rear-end collision protection for the trailer. When the trailer reverses into a parking space or aligns with the loading platform, the rear end is prone to collision, causing deformation or damage to the platform's edges, thus affecting the safety of subsequent loading and unloading. Therefore, a foldable trailer loading platform structure is urgently needed. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a foldable trailer extension platform structure to solve the problems of existing trailer extension platforms, which cannot be folded and stored during use, have fixed dimensions, are limited when loading long, lightweight goods, cannot be loaded and transported completely, have poor adaptability to cargo loading, and cannot provide anti-collision protection for the rear of the trailer. When the trailer reverses into the warehouse or is aligned with the loading and unloading platform, the rear is prone to collision with the platform, resulting in deformation of the rear or damage to the edge of the loading and unloading platform, affecting the safety of subsequent loading and unloading.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable trailer extended cargo platform structure, including a main cargo platform, slide rails installed on both sides of the main cargo platform, a slide groove formed on the inner wall of the slide rail, a base installed at the bottom of the slide rail, a support rod installed at the top of the base, a folding plate installed on the inner wall of the support rod, a lifting lug installed at the top of the folding plate, a fixing shaft penetrating through the interior of the folding plate, an extended cargo platform installed on the inner wall of the slide rail, a positioning rod penetrating through the interior of the extended cargo platform, a reinforcing rod installed at the top of the base, a limiting rod penetrating through the interior of the reinforcing rod, and a limiting sleeve installed on the outer wall of the limiting rod.

[0006] The outer wall of the extended cargo board is fitted with a shock-absorbing cotton plate, and the connecting rod passes through the interior of the shock-absorbing cotton plate.

[0007] Preferably, the main cargo plate is welded to the slide rail, and the folding plate is movably connected to the support rod.

[0008] Preferably, the fixed shaft passes through the interior of the extended cargo plate and is threadedly connected to the main cargo plate, and the extended cargo plate is slidably connected to the slide rail.

[0009] Preferably, the positioning rods are arranged in a rectangular array with the central axis of the base as the center, and the positioning rods are engaged with the bottom of the folding plate.

[0010] Preferably, the interior of the anti-collision cotton board is configured with a honeycomb structure, and the anti-collision cotton board is sleeved with the outer wall of the extended cargo board.

[0011] Preferably, the diameter of the anti-collision cotton plate matches the diameter of the extended cargo plate, and the connecting rod passes through the interior of the anti-collision cotton plate and is threadedly connected to the extended cargo plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of a main cargo plate, slide rail, slide groove, base, support rod, folding plate, lifting lug, fixed shaft, extended cargo plate, positioning rod, reinforcing rod, limiting rod, and limiting sleeve, allows for the extension of the extended cargo plate when the lightweight goods to be loaded are long. The extended cargo plate is pulled outward along the slide groove to the end, then fixed by the positioning rod. The lifting lug is then used to lift the folding plate upward, causing it to flip and align horizontally. It is then initially fixed by the fixed shaft, and the reinforcing rod is rotated vertically to reinforce and support the folding plate. Finally, it is threadedly fixed by the limiting rod and limiting sleeve. The folding plate allows the extended cargo plate to be extended and adjusted to meet the loading needs of lightweight goods of different sizes, making it more versatile.

[0013] 2. This utility model uses an extended cargo plate, a crash barrier, and a connecting rod to connect the crash barrier to the extended cargo plate, and then fix it with threads using the connecting rod. The crash barrier protects the rear of the extended cargo plate when the semi-trailer is reversing into the warehouse or aligning with the loading and unloading platform, preventing deformation of the rear of the extended cargo plate and damage to the edges of the loading and unloading platform.
