[0045] Among them, positioning grooves 10 are opened on the upper surfaces of the four positioning blocks 8;

[0046] Among them, a top cover mechanism is arranged on the four positioning blocks 8, and the top cover mechanism includes a second rotating block 15, a support block 16, a fixing hole 14, a support rod 13, a bolt 9, and a rotating shaft 17;

[0048] Furthermore, the four second rotating blocks 15 are slidably connected in the positioning grooves 10;

[0049] Among them, the upper surface of the second rotating block 15 extends out of the upper surface of the positioning block 8 through the positioning groove 10;

[0050] Among them, the four support blocks 16 are rotatably connected to the four second rotating blocks 15;

[0051] Among them, the four support blocks 16 are arranged in a mirror image.

[0052] Furthermore, the four support blocks 16 are rotatably sleeved on the outer surface of the rotating shaft 17 through bearings;

[0053] Among them, multiple support rods 13 are fixedly connected between the front and rear support blocks 16;

[0054] Among them, multiple fixing holes 14 are opened on the outer surfaces of the four second rotating blocks 15;

[0055] Among them, four bolts 9 are arranged on the four positioning blocks 8, and the end of the bolt 9 close to the positioning block 8 rotates through the positioning groove 10;

[0056] Among them, the end of the bolt 9 close to the positioning block 8 extends into the fixing hole 14 and is slidably connected to the fixing hole 14.

[0057] Furthermore, four sliding grooves 2 are opened on the outer surfaces of the adjacent sides of the left and right fixing blocks 1;

[0058] Among them, eight sliding blocks 4 are slidably connected in the four sliding grooves 2;

[0059] Among them, four bidirectional threaded rods 5 are rotatably connected between the upper and lower inner walls of the four sliding grooves 2;

[0060] Among them, the upper end of the bidirectional threaded rod 5 rotatably penetrates through the upper surface of the fixed block 1.

[0061] Furthermore, eight first rotating blocks 6 are fixedly connected to the eight sliding blocks 4;

[0062] Among them, the eight sliding blocks 4 are threadedly sleeved on the outer surfaces of the four bidirectional threaded rods 5;

[0063] Among them, the upper and lower sliding blocks 4 are respectively located at two different threaded parts of the bidirectional threaded rod 5;

[0064] Among them, four rotating rods 11 are rotatably connected to the eight first rotating blocks 6.

[0065] Furthermore, the four rotating rods 11 are arranged in a cross shape;

[0066] Among them, two fixed columns 12 are arranged on the four rotating rods 11;

[0067] Among them, the fixed column 12 is rotatably sleeved on the two rotating rods 11 arranged in a cross shape, and the fixed column 12 is located at the middle position of the rotating rod 11;

[0068] Among them, four handles 7 are fixedly connected to the upper ends of the four bidirectional threaded rods 5.

[0069] Furthermore, in this solution, a waterproof tarpaulin can be arranged on the upper surface of the support block 16 for waterproofing, sunshading, drainage, etc. The waterproof tarpaulin is an existing technology and will not be elaborated here;

[0070] Furthermore, during use, rotate the bolt 9 so that the bolt 9 rotates out of the fixing hole 14. At this time, the second rotating block 15 can be pulled up and down, so that the second rotating block 15 moves up and down. Furthermore, the height of the support block 16 can be adjusted up and down. When the second rotating block 15 moves to a suitable height, rotate the bolt 9 so that the bolt 9 rotates into the fixing hole 14 at a suitable position, thereby fixing the second rotating block 15, and further fixing the support block 16, so that the height of the tarpaulin rack can be adjusted. The adjustment is convenient and fast. While increasing the practicability and flexibility of the tarpaulin rack, the applicability of the tarpaulin rack can be increased;

[0071] As described above, when the bidirectional threaded rod 5 is rotated, the rotation of the bidirectional threaded rod 5 drives the sliding blocks 4 on the upper and lower sides to move away from or towards each other, thereby driving the first rotating blocks 6 on the upper and lower sides to move synchronously. During this process, the rotating rod 11 rotates crosswise around the fixed column 12. During the crosswise rotation of the rotating rod 11, the fixed blocks 1 on the left and right sides are driven to move in opposite or away directions, thereby driving the support block 16 to rotate around the rotating shaft 17. When the fixed blocks 1 on the left and right sides move away from each other, the support block 16 is opened at this time, thereby increasing the shielding range of the tarpaulin rack. Similarly, the shielding range of the tarpaulin rack can also be reduced, so that the shielding range of the tarpaulin rack can be adjusted, the adjustment is convenient, and the adjustment flexibility is strong. Furthermore, the practicability and flexibility of the tarpaulin rack are increased, making the applicability of the tarpaulin rack more extensive.

[0072] Furthermore, when not in use, the bidirectional threaded rod 5 can be rotated to make the fixed blocks 1 on the left and right sides move relatively, thereby reducing the occupied space of the tarpaulin rack, facilitating the transportation of the tarpaulin rack, and increasing the practicability of the tarpaulin rack.

[0073] Working principle: When the device is in use, by rotating the bolt 9 during use, the bolt 9 is rotated out of the fixing hole 14. At this time, the second rotating block 15 can be pulled up and down, so that the second rotating block 15 moves up and down, thereby adjusting the height of the support block 16 up and down. When the second rotating block 15 moves to a suitable height, rotate the bolt 9 to make the bolt 9 rotate into the fixing hole 14 at a suitable position, thereby fixing the second rotating block 15, and then fixing the support block 16, so that the height of the tarpaulin rack can be adjusted, the adjustment is convenient and fast. While increasing the practicability and flexibility of the tarpaulin rack, the applicability of the tarpaulin rack can be increased;

[0074] As described above, when the bidirectional threaded rod 5 is rotated, the rotation of the bidirectional threaded rod 5 drives the sliding blocks 4 on the upper and lower sides to move away from or towards each other, thereby driving the first rotating blocks 6 on the upper and lower sides to move synchronously. During this process, the rotating rod 11 rotates crosswise around the fixed column 12. During the crosswise rotation of the rotating rod 11, the fixed blocks 1 on the left and right sides are driven to move in opposite or away directions, thereby driving the support block 16 to rotate around the rotating shaft 17. When the fixed blocks 1 on the left and right sides move away from each other, the support block 16 is opened at this time, thereby increasing the shielding range of the tarpaulin rack. Similarly, the shielding range of the tarpaulin rack can also be reduced, so that the shielding range of the tarpaulin rack can be adjusted, the adjustment is convenient, and the adjustment flexibility is strong. Furthermore, the practicability and flexibility of the tarpaulin rack are increased, making the applicability of the tarpaulin rack more extensive.
