[0002] With the rapid development of the logistics and transportation industry, the demand for cargo protection during transportation is increasing. Especially during long-distance transportation or in severe weather conditions, goods are easily damaged by rain, dust, ultraviolet rays, and other external environmental factors, leading to damage or deterioration in quality. Therefore, tarpaulins are needed to cover the goods to provide waterproofing, dustproofing, and UV protection.

[0003] Chinese utility model patent CN220639666U discloses a semi-trailer tarpaulin structure that is easy to deploy and retract. The structure includes a trailer bed, a first mounting frame on one side of the trailer bed, a second mounting frame on the side of the trailer bed away from the first mounting frame, guide plates on both side walls of the trailer bed, and multiple U-shaped movable plates arranged at equal intervals on the guide plates. The U-shaped movable plates located at the same position on both sides of the trailer bed are fixedly connected by a U-shaped support frame. The upper end of the U-shaped support frame is fixedly connected to the tarpaulin, and one end of the tarpaulin is fixedly connected to the first mounting frame. The side of the tarpaulin away from the first mounting frame has multiple equally spaced connecting holes, and the inner side of the second mounting frame has hook assemblies that match the connecting holes.

[0004] The aforementioned patent achieves the raising and lowering of the tarpaulin by sliding several U-shaped support frames between the first mounting frame and the second mounting frame. However, in order to ensure smooth sliding of the U-shaped movable plate and the guide plate when sliding the U-shaped support frames, two workers are required to operate the two ends of the U-shaped support frames to slide synchronously, which makes the raising and lowering of the tarpaulin cumbersome and inefficient.

[0027] To make the technical means, creative features, achieved objectives and functions of this utility model clearer and easier to understand, the utility model will be further described below with reference to the accompanying drawings and specific embodiments:

[0028] like Figure 1-2As shown, an embodiment of this utility model provides a reinforced, slidable, rainproof tarpaulin structure, comprising: a frame 1; a tarpaulin frame, which includes a fixed frame 2 fixedly installed on the upper part of one end of the frame 1, a sliding frame 4 slidably installed on the upper part of the frame 1, and several support frames 3, the several support frames 3 being linearly spaced between the sliding frame 4 and the fixed frame 2, and a tarpaulin body 5 laid between the fixed frame 2, the several support frames 3, and the sliding frame 4; and a sliding adjustment mechanism, which includes a drive part rotatably installed on the end of the frame 1 away from the fixed frame 2, and a connecting part and a transmission part disposed within the frame 1, the power input end of the transmission part being... The drive unit extends through the frame 1 and is connected to the drive unit. The power output end of the transmission unit is movably connected to the connecting unit. The power output end of the connecting unit extends freely through the frame 1 and is connected to the sliding frame 4. A limiting component is provided between the connecting unit and the frame 1. The drive unit drives the connecting unit and the sliding frame 4 to slide along the frame 1 through the transmission unit. During the sliding process of the sliding frame 4, it can drive several support frames 3 to move away from or closer to the fixed frame 2, so that the tarpaulin body 5 between the fixed frame 2, several support frames 3 and the sliding frame 4 covers or opens the frame 1. The operation is simple and convenient, and the tarpaulin body 5 can be quickly put on and taken off, improving the efficiency of putting on and taking off.

[0029] like Figure 2-5 As shown, according to another embodiment of the present invention, the reinforced and slidable rainproof tarpaulin structure further optimizes its transmission part, connecting part and driving part. The upper part of the frame 1 is provided with two sliding grooves 11 parallel to the direction perpendicular to the fixed frame 2. The two sliding grooves 11 are connected to the ends away from the fixed frame 2 and a mounting groove 12 is provided. The transmission part is disposed between the two sliding grooves 11 and the mounting groove 12. The sliding frame 4 and several support frames 3 are all inverted U-shaped structures. The two ends of the sliding frame 4 and several support frames 3 are slidably connected to the two sliding grooves 11 one by one. There are two connecting parts that are slidably disposed in the two sliding grooves 11 one by one.

[0030] The transmission unit includes screws 61 rotatably mounted in two sliding grooves 11, a transmission component disposed in a mounting groove 12, and two bevel gear assemblies connected between the two screws 61 and the transmission component. One screw 61 freely extends out of the frame 1 and is connected to the drive unit. The two connecting parts are threadedly connected to the two screws 61. Two support plates 13 are fixedly mounted facing each other along the length of the mounting groove 12. The transmission component includes a transmission rod 64 rotatably mounted between the two support plates 13. Both ends of the transmission rod 64 freely pass through the two support plates 13 and are connected to the two bevel gear assemblies. Each bevel gear assembly includes a first bevel gear 62 fixedly sleeved on the screw 61 and a second bevel gear 63 coaxially fixedly connected to the corresponding end of the transmission rod 64. The first bevel gear 62 and the second bevel gear 63 mesh.

[0031] The drive unit drives one of the screws 61 to rotate, and through the transmission of the first bevel gear 62 and the second bevel gear 63 in the two bevel gear assembly, drives the other screw 61 to rotate synchronously, so that the two connecting parts that are threaded to the two screws 61 slide synchronously and in the same direction along the two sliding grooves 11.

[0032] Each of the connecting parts includes a connecting block 41 slidably disposed in the corresponding slide groove 11. One end of the connecting block 41 is threadedly connected to the corresponding screw 61, and the other end freely extends out of the slide groove 11 and is fixedly connected to the corresponding end of the sliding frame 4. The limiting member is disposed between the connecting block 41 and the frame 1. Each of the connecting blocks 41 is provided with a threaded groove 42. Each of the limiting members includes a limiting bolt 7 that is threaded through the frame 1 and into the mounting groove 12. The limiting bolt 7 is used to be threadedly connected to the threaded groove 42 of the corresponding connecting block 41. When the sliding frame 4 slides away from the fixed frame 2 and is in place, each threaded groove 42 is positioned directly opposite the corresponding limiting bolt 7. Then, each limiting bolt 7 is turned to make it threadedly connected to the corresponding threaded groove 42, thereby limiting the position of the sliding frame 4.

[0033] The drive unit includes a handwheel 6 rotatably disposed on the side of the frame 1 away from the fixed frame 2, wherein a screw 61 freely extends out of the frame 1 and is coaxially and fixedly connected to the handwheel 6.

[0034] like Figure 2-3 As shown, according to another embodiment of the present invention, the reinforced and slidable rainproof tarpaulin structure preferably has a slider 31 fixedly installed at both ends of each of the support frames 3, and the two sliders 31 are slidably connected to the two sliding grooves 11 in a one-to-one correspondence; this can ensure the stability of the sliding of the several support frames 3.

[0035] The working principle of this utility model is as follows: When using this utility model, rotating the handwheel 6 drives one of the screws 61 to rotate. Through the transmission of the first bevel gear 62 and the second bevel gear 63 in the two bevel gear assembly, the other screw 61 is driven to rotate synchronously. This causes the two connecting blocks 41, which are threadedly connected to the two screws 61, to slide synchronously along the two sliding grooves 11 and away from the fixed frame 2, thereby driving the sliding frame 4 and several support frames 3 to slide until the threaded groove 42 on each connecting block 41 is aligned with the corresponding limiting bolt 7. Then, each limiting bolt is tightened. Bolt 7 is threaded to connect with the corresponding threaded groove 42, thereby limiting the position of the sliding frame 4. At this time, the tarpaulin body 5 between the fixed frame 2, several support frames 3 and the sliding frame 4 covers the entire frame 1. Conversely, each limiting bolt 7 is loosened first to disengage it from the corresponding threaded groove 42. Then, the handwheel 6 is turned in the opposite direction so that the two screws 61 drive the two connecting blocks 41 to slide synchronously along the two sliding grooves 11 toward the fixed frame 2, thereby folding up the tarpaulin body 5 between the fixed frame 2, several support frames 3 and the sliding frame 4.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
