[0031] Refer to Figure 1 - Figure 2 , an embodiment provided by the present utility model: a semi-trailer carriage guardrail plate that is convenient for installation and adjustment, including a compartment body 1. The compartment body 1 is the main body of the semi-trailer carriage. A fixed column 3 is fixedly connected to the upper end of the compartment body 1. The fixed column 3 can fixedly support the railing plate 2. A fixing component is slidably connected to the outer side of the side end of the fixed column 3. The fixing component includes a connecting plate 5. The connecting plate 5 can be conveniently fixedly connected to the fixed column 3 through a bolt 6. A bolt 6 is threadedly connected to the inside of the connecting plate 5. The bolt 6 can keep the railing plate 2 fixed relative to the fixed column 3. The side end of the connecting plate 5 is in contact with the outer side of the side end of the fixed column 3. The connecting plate 5 can be positioned and installed conveniently by sliding vertically to a position in contact with the fixed column 3. The side end of the connecting plate 5 is fixedly connected to the outer side of the side end of the railing plate 2. The connecting plate 5 is kept in a relatively fixed position by the railing plate 2. The outer side of the bolt 6 is threadedly connected to the inside of the side end of the fixed column 3. The bolt 6 is kept relatively fixed by the fixed column 3.

[0032] Refer toFigure 1 - Figure 2 , a railing plate 2 is fixedly connected to the side end of the fixing component. The railing plate 2 is the main body of the carriage guardrail plate. The side end of the railing plate 2 is in contact with the side end of the fixing column 3. Multiple square grooves are opened at the lower end of the railing plate 2. A positioning block 12 is slidably connected inside the lower end of the railing plate 2. The positioning block 12 slides inside the square groove so that the railing plate 2 can only slide vertically relative to each other. A fixing block 4 is fixedly connected to the lower end of the positioning block 12. The fixing block 4 can fix the positioning block 12 and the support block 11. The upper part of the fixing block 4 is in contact with the lower part of the railing plate 2 and the upper part of the fixing block 4. The fixing block 4 can support and fix the railing plate 2. A fixing plate 10 is fixedly connected inside the fixing block 4. The fixing plate 10 can limit the block 11 to only slide horizontally relative to the fixing block 4 within a fixed distance. The outside of the fixing plate 10 is slidably connected with a block 11. The block 11 is L-shaped and the upper end is beveled, which can facilitate the installation of the fixing block 4 when it slides upward without blocking at the lower end of the railing plate 2.

[0033] Refer to Figure 1 - Figure 3 , the front end of the block 11 is elastically connected to the upper end inside the fixing block 4 through a first spring 9. The upper end of the block 11 is slidably connected to the side part of the lower end of the railing plate 2. The block 11 can keep the railing plate 2 from sliding vertically relative to each other and keep the railing plate 2 relatively fixed. One end of the first spring 9 is fixedly connected to the front side part of the block 11, and the other end of the first spring 9 is fixedly connected to the upper end inside the fixing block 4. By horizontally sliding the block 11, the fixing block 4 can be slid down and removed for recycling, reducing waste. A square block 8 is fixedly connected to the left end of the fixing block 4. The square block 8 can make the clamping block 7 only slide horizontally relative to the fixing block 4. A clamping block 7 is slidably connected inside the square block 8. The clamping block 7 can fix the railing plate 2 at a predetermined height so that the railing plate 2 is fixed relative to the position of the fixing column 3, facilitating the fixed installation of the bolt 6 and increasing the simplicity of the installation. The rear part of the clamping block 7 is slidably connected to the side end inside the fixing column 3. A clamping component is slidably connected to the side part of the lower end of the railing plate 2.

[0034] Refer to Figure 1 , Figure 3 and Figure 4, the clamping assembly includes a slider 13, which is fixedly composed of a square block and an L-shaped block at the front end, enabling the slider 13 to slide horizontally and linearly relative to the railing plate 2 within a fixed distance. The front part of the slider 13 is slidably connected to the inside of the front end of the railing plate 2. A horizontal groove is provided at the side end of the railing plate 2, allowing the slider 13 to slide horizontally only relative to the railing plate 2, so that rapid adjustment can be made according to the position of the hook. A clamping block 14 is slidably connected to the middle inside of the slider 13. The clamping block 14 is composed of a U-shaped block at the lower end and a vertical rod at the upper end. The U-shaped block can clamp the hook fixed at the lower end of the railing plate 2 to keep it fixed and prevent it from sliding down and falling off or becoming loose. Inside the upper end of the clamping block 14, a slope block 16 is elastically connected by a second spring 15. A groove is provided at the side end of the vertical rod, and the opening width is smaller than the internal width to prevent the clamping block 14 from sliding out completely. The upper part of the lower end of the clamping block 14 contacts the lower part of the railing plate 2. The clamping block 14 can prevent the hook from sliding down and keep it relatively fixed, and the hook can block the clamping block 14 to prevent it from sliding to a position where it cannot clamp the hook. One end of the second spring 15 is fixedly connected to the inside of the upper end of the clamping block 14, and the other end of the second spring 15 is fixedly connected to the left side of the slope block 16. The second spring 15 can maintain the state of the side end of the slope block 16 sliding out. The lower part of the slope block 16 contacts the upper part of the slider 13, and the slope block 16 restricts the clamping block 14 from sliding down and keeps it fixed.

[0035] Working principle: Slide down from the upper end so that the connecting plates 5 at both ends of the railing plate 2 can clamp the fixed column 3, enabling the railing plate 2 to slide vertically. Then slide to the appropriate position and horizontally slide so that the clamping block 7 slides into the fixed column 3 to keep the square block 8 relatively fixed. The square block 8 fixes the side fixed block 4. The fixed block 4 makes the railing plate 2 relatively fixed through the positioning block 12 and the side clamping block 11. Then rotate the bolt 6 to fix the bolt 6 by the fixed column 3, so that the railing plate 2 is fixed to the side of the fixed column 3 to maintain stability. When disassembly is required, the bolt 6 can be rotated to slide it out, then slide out the clamping block 7, remove the railing plate 2 by sliding it up, and horizontally slide the clamping block 11 to slide it out of the inside of the side end of the railing plate 2 to compress the first spring 9. Then the fixed block 4 can be removed by sliding it down. During installation, slide the fixed block 4 up so that the positioning block 12 slides up into the square groove at the lower end of the railing plate 2. At this time, the upper slope of the clamping block 11 is squeezed and slides out to compress the first spring 9. When the upper end of the fixed block 4 contacts the lower end of the railing plate 2, the clamping block 11 slides into the inside of the side end of the railing plate 2 under the compression of the first spring 9 to keep it fixed. When a hook needs to be installed, the slope block 16 can be squeezed to slide into the vertical rod to compress the second spring 15. Then manually slide the clamping block 14 down, and then hang the hook in the square groove. Slide the clamping block 14 up to clamp and fix the hook at the lower end and the railing plate 2. At this time, the slope block 16 slides out under the compression of the second spring 15 to keep the clamping block 14 fixed.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features.
