[0002] Tarpaulin structures are widely used in numerous fields, including outdoor operations, warehouse protection, and temporary construction, as they provide temporary shelter and protection. Whether it's covering goods in industrial production or protecting crops in agriculture, tarpaulin structures are indispensable. With the increasing demand for temporary protection across industries, higher requirements are being placed on the performance and ease of use of tarpaulin structures.

[0003] Existing tarpaulin mechanisms present numerous problems in practical use. Traditional tarpaulin setup and takedown processes often require multiple people working together, making the operation cumbersome and time-consuming. This is because their complex structural design necessitates the assembly and disassembly of multiple components; for example, some tarpaulins require extensive rope binding or bolt fixing, which is not only physically demanding but also difficult to deploy quickly in emergencies. Furthermore, existing tarpaulin mechanisms also suffer from instability. Some connections are not robust enough, making them prone to loosening or even collapse in severe weather conditions such as wind and rain, failing to effectively protect the safety of items or personnel inside. To address these technical problems, this application proposes a simple, lightweight tarpaulin mechanism. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3This utility model provides an embodiment of a simple and lightweight tarpaulin mechanism, including a storage cylinder 1. A winding roller is rotatably connected to the inner wall of the storage cylinder 1, and a tarpaulin body 2 is provided on the outer wall of the winding roller. An annular sleeve is fixedly connected to the other end of a side support guide rail 4. Locking blocks 6 are fixedly connected to the outer walls of both the annular sleeve and the storage cylinder 1. Locking rings 7 are provided on the outer walls of two adjacent locking blocks 6. Threads are provided on the outer walls of both the locking blocks 6 and the inner walls of the locking rings 7. A limit strip 3 is fixedly connected to one side of the tarpaulin body 2. A slider 11 is fixedly connected to both the front and rear ends of the limit strip 3. The slider 11 is located inside the side support guide rail 4 and is slidably connected to a limit pin 12 on the top side of the side support guide rail 4. A limit hole is provided on the outer wall of the slider 11, and the bottom end of the limit pin 12 is located in the limit hole. Inside, a return spring 13 is provided on the outer wall of the limiting insert shaft 12. One end of the return spring 13 is connected to the limiting insert shaft 12, and the other end of the return spring 13 is connected to the top side of the side support guide rail 4 for unfolding the tarpaulin body 2. A protective shell 14 is fixedly connected to the rear end of the storage tube 1. The inner wall of the protective shell 14 is connected to the winding roller through a spiral spring 15 for storing the tarpaulin body 2. A slide rod 8 is fixedly connected to the outer wall of the storage tube 1. Two arc-shaped clamps 10 are slidably connected to the outer wall of the slide rod 8. A double-headed threaded rod 9 is rotatably connected to the outer wall of the storage tube 1. The arc-shaped clamps 10 are set on the outer wall of the double-headed threaded rod 9. A rotating wheel is fixedly connected to the rear end of the double-headed threaded rod 9 for installing the storage tube 1. A support frame 5 is rotatably connected to the bottom side of the side support guide rail 4. Specifically, during tarpaulin setup, firstly, the rotating wheel drives the double-threaded rod 9 to rotate, thereby controlling the two arc-shaped clamps 10 to slide along the outer wall of the slide bar 8, installing the arc-shaped clamps 10 into the desired position. Next, the annular sleeve on the side support guide rail 4 is fitted onto the outer wall of the storage cylinder 1, at which point the two adjacent locking blocks 6 will fit together. Then, the locking ring 7 is fitted onto the outer wall of the locking block 6, and the threaded engagement between the inner wall of the locking ring 7 and the outer wall of the locking block 6 completes the fixed installation between the storage cylinder 1 and the side support guide rail 4. Afterward, the support frame 5 is rotated and inserted into the ground to set up the tarpaulin. Next, the limiting strip 3 is pulled, causing the slider 11 to move along the groove on the inner wall of the side support guide rail 4 to the desired position. Finally, the limiting insert 12 is pulled, and with the reset action of the return spring 13, the limiting insert 12 is inserted into the limiting hole on the outer wall of the slider 11, thereby completing the unfolding of the tarpaulin body 2. When storing the tarpaulin, first pull out the limiting insert 12. Using the elasticity of the spiral spring 15, the winding roller on the inner wall of the storage cylinder 1 winds the tarpaulin body 2. Then, rotate the support frame 5 so that it is magnetically attached to the bottom of the side support rail 4. Next, disengage the locking ring 7 from the locking block 6 and remove the annular sleeve. Finally, remove the storage cylinder 1 from its fixed position, completing the storage of the tarpaulin. The entire process demonstrates the convenience of tarpaulin handling.

[0019] Reference Figures 2-4 Magnets are provided on the adjacent side of the support frame 5 and the side support rail 4; Specifically, by setting magnets on the adjacent sides of the support frame 5 and the side support rail 4, the support frame 5 and the side support rail 4 can be fixed together to prevent the support frame 5 from swinging.

[0020] Working principle: First, the storage cylinder 1 is rotated by a rotating wheel, which drives the double-headed threaded rod 9 to rotate, controlling the sliding of two arc-shaped clamping blocks 10 on the outer wall of the slide rod 8. After the two arc-shaped clamping blocks 10 are installed in the required position, the annular sleeve on the side support guide rail 4 is placed on the outer wall of the storage cylinder 1. At this time, the two adjacent locking blocks 6 will stick together. Then, the locking ring 7 is placed on the outer wall of the two locking blocks 6. Through the threaded engagement between the inner wall of the locking ring 7 and the outer wall of the locking block 6, the installation between the storage cylinder 1 and the side support guide rail 4 is achieved. Then, the support frame 5 is rotated and inserted into the ground to set up the tarpaulin. Finally, by pulling the limiting strip 3, the slider 11 is moved along the side support guide rail. 4. Pull the inner wall of the slide groove to the desired position, and then pull the limiting insert 12 to insert it into the limiting hole on the outer wall of the slider 11 by the reset spring 13, so as to unfold the tarpaulin body 2. When storing, simply pull out the limiting insert 12 and the spiral spring 15 causes the winding roller on the inner wall of the storage cylinder 1 to wind the tarpaulin body 2. Then rotate the support frame 5 and attach it to the bottom side of the side support guide rail 4 by magnet. Then separate the locking ring 7 and the locking block 6. Then remove the annular sleeve from the outer wall of the storage cylinder 1. Finally, disassemble the storage cylinder 1 from the fixed place to realize the convenience of the tarpaulin.
