[0029] Refer to Figures 1-3, an embodiment provided by the present utility model: a tarpaulin support device for a freight truck, including a connecting plate 1. Two limiting rods 2 are fixedly connected to both the left and right ends of the connecting plate 1. A nut pair 3 is rotatably connected to one side of two adjacent front and rear limiting rods 2. Then the connecting plate 1 can be installed. By rotating the nut pair 3, the first threaded rod 4 is driven to rotate within the limiting rod 2, and the first threaded rod 4 can be inserted into the insertion ring 8. When the first threaded rod 4 rotates, it will rotate into the insertion ring 8 for fixation, and the length of the first threaded rod 4 can be adjusted, with better use effect. The inner diameters of two adjacent front and rear nut pairs 3 are threadedly connected with the first threaded rod 4. When disassembly is required, only the nut pair 3 needs to be rotated to drive the first threaded rod 4 to rotate within the limiting rod 2 and separate from the insertion ring 8. Then, the nut 11 is rotated and removed in sequence, and the U-shaped pressing plate 9 can be removed upward. One side of two adjacent front and rear first threaded rods 4 is threadedly connected with an insertion ring 8. One side of two adjacent front and rear insertion rings 8 penetrates and is fixedly connected with a cross beam 6. Both the left and right ends of the two cross beams 6 are fixedly connected with sliding plates 7. When using the tarpaulin support device, during installation, first, the sliding plate 7 is inserted into the limiting plate 13 according to the track of the sliding groove 5 for positioning. Two support rods 14 are arranged at the bottom of two adjacent left and right cross beams 6. Limiting plates 13 are fixedly connected to the left and right ends of the top of two adjacent front and rear support rods 14. Sliding grooves 5 are opened on the opposite sides of two adjacent left and right limiting plates 13. Two U-shaped pressing plates 9 are arranged at the top of the two cross beams 6. Two second threaded rods 10 are fixedly connected to the bottom of two adjacent front and rear U-shaped pressing plates 9. Then, the U-shaped pressing plate 9 is placed above the cross beam 6, and the second threaded rod 10 is inserted into the inner part of the limiting ring 12, and then fixed with the nut 11. Limiting rings 12 are fixedly connected to the opposite sides of two adjacent left and right limiting plates 13.

[0030] The first threaded rod 4 is rotatably connected with the limiting rod 2. The bottom of the support rod 14 is fixedly connected with a base 15. A traction ring 16 is fixedly connected to one side of two adjacent front and rear support rods 14. The sliding plates 7 are slidably connected to the inner walls of two adjacent left and right sliding grooves 5. Then, the cross beam 6 is lifted upward to slide the sliding plate 7 out of the limiting plate 13, and the cross beam 6 can be disassembled, which is simple and convenient to use. A nut 11 is arranged at the bottom of the limiting ring 12. The nut 11 is slidably connected to the inner diameter of the limiting ring 12. The nut 11 is threadedly connected to the surface of the second threaded rod 10.

[0031] Working principle: When using the tarpaulin support device, during installation, first insert the sliding plate 7 along the track of the sliding groove 5 so that the sliding plate 7 is inserted into the limiting plate 13 for positioning. Then place the U-shaped pressing plate 9 above the cross beam 6, insert the second threaded rod 10 into the limiting ring 12, and then fix it with the nut 11. Next, the connecting plate 1 can be installed. Rotate the nut pair 3 to drive the first threaded rod 4 to rotate within the limiting rod 2, so that the first threaded rod 4 is inserted into the insertion ring 8. When the first threaded rod 4 rotates, it will rotate into the insertion ring 8 for fixation, and the length of the first threaded rod 4 can be adjusted, resulting in a better use effect. When disassembly is required, only rotate the nut pair 3 to drive the first threaded rod 4 to rotate within the limiting rod 2 and separate it from the insertion ring 8. Then, sequentially rotate and remove the nut 11, and the U-shaped pressing plate 9 can be removed upward. Then lift the cross beam 6 upward so that the sliding plate 7 slides out of the limiting plate 13, and the cross beam 6 can be disassembled. It is simple and convenient to use.
