[0026] Please refer to Figure 1-6, the present utility model provides a technical solution: a new type of waterproof step, including a waterproof step main body 1 and a patterned bottom plate 2. An irregular-shaped pipe 3 is provided on the waterproof step main body 1. The irregular-shaped pipe 3 is made of Q235 steel, and the thickness of the irregular-shaped pipe 3 is at least 1.0 mm. Moreover, the maximum width and maximum height of the irregular-shaped pipe 3 are both 50 mm. The material thickness of the irregular-shaped pipe 3 in this structure can be 1.0 mm, 1.2 mm, 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm. Select the appropriate thickness according to the vehicle model requirements. And a connecting surface 4, a waterproof surface 5, and a water guiding surface 6 are successively arranged on the irregular-shaped pipe 3. The bottom surface of the end of the patterned bottom plate 2 is welded and fixed to the connecting surface 4 at the upper end of the irregular-shaped pipe 3, and the weld between the patterned bottom plate 2 and the connecting surface 4 is on the outside. This structure allows the patterned bottom plate 2 in the truck cargo compartment to be fixed by the side beams formed by the irregular-shaped pipes 3, and the step structure of the irregular-shaped pipes 3 itself is used for waterproofing the cargo compartment. And the connecting surface 4, the waterproof surface 5, and the water guiding surface 6 form a step structure. The connecting surface 4 is horizontally arranged, and the width of the connecting surface 4 is 24.5 mm. By arranging the connecting surface 4 horizontally in this structure, the welding part between the connecting surface 4 and the patterned bottom plate 2 is in close contact, ensuring the welding quality. At the same time, the connecting surface 4 provides sufficient support area for the patterned bottom plate 2. The waterproof surface 5 is vertically arranged, and the height of the waterproof surface 5 is 25 mm. This structure can block water from entering the cargo compartment through the waterproof surface 5. The water guiding surface 6 is horizontally arranged and slopes downward by 1-2°. This structure allows water to quickly drain away through the inclined setting of the water guiding surface 6, avoiding water accumulation at the step. A positioning hole 9 is also opened on the side of the irregular-shaped pipe 3, and a support plate 7 is inserted at the positioning hole 9. The thickness of the support plate 7 is greater than the thickness of the irregular-shaped pipe 3, and the support plate 7 is an L-shaped flat plate structure. This structure can be stably supported by the support plate 7 inside the irregular-shaped pipe 3. The support plates 7 can be distributed at both ends and the middle position of the irregular-shaped pipe 3. The groove part of the L-shaped structure of the support plate 7 is tightly clamped with the inner sides of the waterproof surface 5 and the water guiding surface 6. This structure allows the support plate 7 to support the waterproof surface 5 and the water guiding surface 6 inside the irregular-shaped pipe 3 to prevent the irregular-shaped pipe 3 from deforming, making the overall strength of the irregular-shaped pipe 3 higher. And a connecting plate 8 is connected to the outer end of the support plate 7. Chamfers are provided at the corners of the irregular-shaped pipe 3, and the irregular-shaped pipe 3 is welded and fixed to the connecting plate 8. And through holes corresponding in position are opened on the irregular-shaped pipe 3 and the connecting plate 8. This structure enables the connecting plate 8 to reinforce the screwing part between the irregular-shaped pipe 3 and other components. The connecting plate 8 is welded and fixed to the side of the irregular-shaped pipe 3. A T-shaped structure is formed by welding between the support plate 7 and the connecting plate 8, and the vertical height of the support plate 7 is less than the height of the connecting plate 8. This structure stably processes the connection between the support plate 7 and the irregular-shaped pipe 3 through the connecting plate 8.
[0027] Working principle: When using this new type of waterproof step, first, the special-shaped pipe 3 forms the side beam of the truck cargo box. The support plate 7 and the connecting plate 8 are welded to form a T-shaped structure. The support plate 7 is inserted into the special-shaped pipe 3 from the positioning hole 9. The special-shaped shape of the special-shaped pipe 3 is supported and reinforced by the support plate 7, and the support plate 7 is welded to the special-shaped pipe 3, so that the special-shaped pipe 3 can also be reinforced at the connection position through the support plate 7, further improving the strength of the special-shaped pipe 3. The special-shaped pipe 3 is welded by the connection surface 4 and the patterned bottom plate 2. The step structure composed of the connection surface 4, the waterproof surface 5 and the water guiding surface 6 is used for waterproof treatment of the cargo box. The water guiding surface 6 is inclined to accelerate the drainage speed, realizing the efficient waterproofing of the waterproof step main body 1, and thus completing a series of work.
