Description

Technical Field

[0001] This utility model relates to the field of tarpaulin structure technology, and in particular to a truck tarpaulin structure that is easy to assemble and disassemble. Background Technology

[0002] During transport, bulk cargo on semi-trailers is highly susceptible to scattering, posing significant safety hazards to the environment, pedestrians, and road traffic. Therefore, covering the top of the truck with a tarpaulin is a necessary measure to ensure the safe operation of the truck. The tarpaulin is frequently uncovered and covered during loading and unloading of cargo.

[0003] A search revealed Chinese Patent Publication No. CN222136593U, which discloses a conveniently disassembled truck tarpaulin structure, belonging to the field of tarpaulin technology. Multiple lower arms are slidably arranged within a T-shaped slide rail. A first upper arm and a second upper arm are movably mounted on the lower arms on both sides. The first and second upper arms have locking holes that cooperate with a quick-lock mechanism. A locking rod is movably mounted within a locking groove. A locking block that cooperates with a locking fan is provided on the inner wall of the locking hole. A return spring is also provided between the locking groove and the adjusting cap. Multiple slots are opened on both sides of the crossbeam, and locking springs are installed within the slots. Ball bearings are connected to the sides of the locking springs. Grooves that cooperate with the ball bearings are opened on the inner walls of both sides of the positioning frame. This utility model allows for quick storage and unfolding of the tarpaulin using the T-shaped slide rail and slider. Furthermore, the upper arms can be quickly disassembled and assembled with the cooperation of the quick-lock mechanism and locking holes. The ball bearings and grooves allow for adjustment according to the width of the truck bed, thus improving the practicality of the tarpaulin structure.

[0004] While the above solution has the advantage of improving the practicality of the tarpaulin structure, the operation of disassembling and assembling the upper arm through the quick-lock mechanism and locking holes to adjust the height of the tarpaulin is rather cumbersome. Moreover, the lack of support structures on the sides of the upper and lower arms results in poor stability of the tarpaulin after installation.

[0005] Therefore, there is an urgent need to provide a truck tarpaulin structure that is easy to assemble and disassemble to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the above-mentioned prior art, which is that the upper arm is disassembled and assembled by the cooperation of quick-lock structure and locking hole in actual use to adjust the height of the tarpaulin. The operation is relatively cumbersome, and the upper and lower arms are not provided with support structure, resulting in poor stability of the tarpaulin after installation. This utility model provides a truck tarpaulin structure that is easy to disassemble and assemble.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing a truck tarpaulin structure that is easy to assemble and disassemble, including a truck body, and further including:

[0021] 1. This utility model, through the setting of the adjustment component, when it is necessary to adjust the height of the tarpaulin, works with the pusher to push the lifting plate up or down, and works with the vertical rod to improve the stability of the lifting plate during movement. At this time, the push block is inserted into the inside of the limiting hole. After the adjustment is completed, the threaded rod is rotated to drive the movable plate and the push block to move outward of the limiting hole, so that the limiting block engages with the limiting hole under the elastic squeezing action of the squeezing component, which facilitates the adjustment of the height of the lifting plate and the operation is relatively quick;

[0022] 2. This utility model uses a support unit to adjust the position of a sliding U-shaped frame. After adjustment, the locking rod is rotated so that one end engages with the locking groove, thereby limiting the position of the U-shaped frame. This, combined with the support rod, provides limiting support for the U-shaped frame, improving its stability. Attached Figure Description

[0034] The lifting plate 31 has a groove 311 on its outer side, and a slider 312 is movably arranged inside the groove 311. The bottom end of the U-shaped frame 2 is fixedly connected to the outer side of the slider 312.

[0035] The outer surface of the U-shaped frame 2 is provided with threaded holes 21. Preferably, there are multiple threaded holes 21, which are equidistantly distributed on the outer surface of the U-shaped frame 2. By using the threaded holes 21 and bolts, the tarpaulin can be easily fixed to the outside of the U-shaped frame 2, thus facilitating the assembly and disassembly of the tarpaulin.

[0036] The lifting unit 32 includes a vertical rod 321 fixedly connected to the outer side of the carriage 1. The top surface of the lifting plate 31 has a through hole, and the vertical rod 321 is disposed inside the through hole. The bottom of the lifting plate 31 is provided with a pusher 322. Preferably, the pusher 322 is a cylinder, and the two ends of the pusher 322 are rotatably connected to the bottom of the outer side of the carriage 1 and the bottom of the lifting plate 31, respectively.

[0037] Each lifting plate 31 has a limit unit 33 at both ends;

[0038] The limiting unit 33 includes a storage groove disposed at the end of the lifting plate 31, one end of an extrusion member 331 fixedly disposed on the side wall of the storage groove, and a limiting block 332 fixedly connected to the other end of the extrusion member 331.

Then, the tarpaulin is fixedly connected to the outside of the U-shaped frame 2 by bolts and threaded holes 21.

[0043] When the height of the tarpaulin needs to be adjusted, the lifting plate 31 is moved up or down by the pusher 322, and the vertical rod 321 is used to improve the stability of the lifting plate 31 during movement. At this time, the push block 344 is inserted into the limiting hole 333. After the adjustment is completed, the threaded rod 342 is rotated to drive the movable plate 343 and the push block 344 to move outward of the limiting hole 333. This causes the limiting block 332 to engage with the limiting hole 333 under the elastic compression of the extruder 331, thereby limiting the height of the lifting plate 31, which is convenient and quick.
