Description

Technical Field

[0001] This utility model belongs to the field of road freight transport technology, and in particular relates to a vehicle box covering device for road freight transport. Background Technology

[0002] Road freight transport refers to production activities that use trucks as the main means of transportation to move goods spatially via roads. This mode of transport is characterized by its flexibility, speed, adaptability, and economy, making it suitable for various scales and types of freight transport needs. However, existing technologies have the following problems: when traveling on highways, goods face significant wind resistance, and uncovered goods are easily blown off. Furthermore, goods are susceptible to external environmental factors such as wind, rain, and dust. Some goods also require sun protection. Therefore, tarpaulins are needed to cover the truck bed during road freight transport. Current tarpaulins require multiple ropes for securing them, but these ropes are unstable, and breakage can easily cause goods to fall, potentially posing a traffic safety hazard. Moreover, rope installation and removal are time-consuming and inconvenient. Currently, there are no convenient components for covering transported goods in existing road freight transport truck beds. Therefore, a road freight transport truck bed covering device is proposed to solve these problems. Utility Model Content

[0003] To address the problems of existing technologies, this utility model provides a vehicle body covering device for road freight transport. This device offers the advantage of conveniently covering transported goods in the vehicle body, solving the problem that existing road freight transport vehicles face high wind resistance when traveling on highways, making uncovered goods easily blown off by the wind. Furthermore, goods are susceptible to external environmental factors such as wind, rain, and dust, and some goods require sun protection. Therefore, tarpaulins are needed to cover the vehicle body during road freight transport. However, existing tarpaulins require multiple ropes for securing them, which have poor stability. If the ropes break, goods can easily fall, potentially causing traffic safety hazards. Moreover, the installation and removal of ropes are time-consuming and inconvenient. The problem is that existing road freight transport vehicles lack components for conveniently covering transported goods.

[0004] This utility model is implemented as follows: a vehicle body covering device for road freight transport includes a vehicle body and two movable frames. The opposite sides of the two movable frames are fixedly connected to the left and right sides of the vehicle body. The top of the vehicle body is provided with several tarpaulin frames, and a tarpaulin is provided on the top of the vehicle body. The top of the tarpaulin is fixedly connected to the inner cavity of the tarpaulin frames. The top of the movable frames is fixedly connected with two fixing blocks, and the bottom of the movable frames is provided with a fixing shell. The left and right sides of the vehicle body are fixedly connected with fixing clips that cooperate with the fixing shells. The surface of the fixing shell contacts the inner cavity of the fixing clips. The inner cavity of the fixing shell is movably connected with a control block. The side of the control block away from the vehicle body passes through the fixing shell and extends to the outside of the inner cavity of the fixing shell. The inner cavity of the fixing shell is provided with a movable structure.

[0005] As a preferred embodiment of this utility model, the movable structure includes two movable blocks, each with a movable hole on its surface. Two springs are fixedly connected to opposite sides of the two movable blocks. By setting the movable structure, when the mounting block needs to be inserted into or removed from the inner cavity of the mounting groove, the movable structure restricts the movement position of the mounting block.

[0006] As a preferred embodiment of this utility model, the inner cavity of the fixed shell is fixedly connected to two movable rods that cooperate with the movable holes. The surface of the movable rods is movably connected to the inner cavity of the movable holes. By setting the movable rods, when the mounting block moves, it will drive the movable holes to move along the surface of the movable rods. The cooperation between the movable holes and the movable rods has a limiting effect on the movement position of the mounting block.

[0007] As a preferred embodiment of this utility model, each of the two movable blocks is fixedly connected to an installation block on its opposite side. The opposite sides of the two installation blocks penetrate the fixed shell and extend to the outer side of the inner cavity of the fixed shell. By setting the installation blocks, when the fixed shell moves to the inner cavity of the fixed slot, the control block is released, and the restoring force generated by the spring returning to its shape will drive the installation blocks to be engaged in the inner cavity of the installation slot. The cooperation between the installation blocks and the installation slot has a limiting effect on the position of the fixed shell.

[0008] As a preferred embodiment of this utility model, the surface of the movable block is provided with an extrusion hole, and the side of the control block near the carriage is fixedly connected to an extrusion frame that cooperates with the extrusion hole. The surface of the extrusion frame is movably connected to the inner cavity of the extrusion hole. By setting the extrusion hole and the extrusion frame, when the control block rotates, it will drive the extrusion frame to rotate along the inner cavity of the extrusion hole. The extrusion force generated by the extrusion frame on the extrusion hole can drive the two movable blocks to move.

[0009] As a preferred embodiment of this utility model, the inner cavity of the fixing clip is provided with an installation groove for use with the installation clip. The surface of the installation clip contacts the inner cavity of the installation groove. By setting the installation groove, when the tarpaulin completely covers the vehicle body, the installation clip is moved into the inner cavity of the installation groove. The use of the installation clip and the installation groove together restricts the position of the tarpaulin.

[0010] In a preferred embodiment of this invention, the inner cavity of the movable frame is movably connected to several movable sliders. The bottom of the tarpaulin frame is fixedly connected to the top of the movable sliders and the fixed block, and the top of the fixed shell is fixedly connected to the bottom of the movable sliders. By setting the movable sliders, when the tarpaulin frame moves, it will drive the movable sliders to move along the inner cavity of the movable frame. The combined use of the movable sliders and the movable frame has a limiting effect on the movement position of the tarpaulin frame and the tarpaulin.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model solves the problem of high wind resistance for goods traveling on highways, where uncovered goods are easily blown off by the wind, and goods are easily affected by external environmental factors such as wind, rain, and dust. Some goods also require sun protection treatment. Therefore, tarpaulins need to be covered on the truck bed during road freight transport. Existing tarpaulins require multiple ropes for fixing, but the ropes are not very stable. If the ropes break, the goods may fall off, even causing traffic safety hazards. Moreover, the installation and removal of ropes are time-consuming and inconvenient. However, existing road freight transport truck beds do not have components for conveniently covering transported goods.

[0013] 2. By setting a movable structure, the extrusion hole subjected to the extrusion pressure will drive the two movable blocks to move closer to each other. When the movable blocks move, they will drive the movable hole to move along the surface of the movable rod. When the movable blocks move, the force generated will cause the spring to undergo elastic deformation. The restoring force generated by the spring returning to its shape will drive the mounting block to be inserted into the inner cavity of the mounting groove. The movable structure has a limiting effect on the movement position of the mounting block. Attached Figure Description

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown in the figure, an embodiment of the present invention provides a vehicle body covering device for road freight transport, including a vehicle body 1 and two movable frames 2. The opposite sides of the two movable frames 2 are fixedly connected to the left and right sides of the vehicle body 1. A plurality of tarpaulin frames 3 are provided on the top of the vehicle body 1. A tarpaulin 4 is provided on the top of the vehicle body 1. The top of the tarpaulin 4 is fixedly connected to the inner cavity of the tarpaulin frame 3. Two fixing blocks 5 are fixedly connected to the top of the movable frames 2. A fixing shell 7 is provided at the bottom of the movable frames 2. Fixing clips 6 that cooperate with the fixing shell 7 are fixedly connected to the left and right sides of the vehicle body 1. The surface of the fixing shell 7 is in contact with the inner cavity of the fixing clip 6. A control block 8 is movably connected to the inner cavity of the fixing shell 7. The side of the control block 8 away from the vehicle body 1 penetrates the fixing shell 7 and extends to the outside of the inner cavity of the fixing shell 7. A movable structure 9 is provided in the inner cavity of the fixing shell 7.

[0022] refer to Figure 4 The movable structure 9 includes two movable blocks 901. The surface of the movable blocks 901 is provided with movable holes 902. Two springs 903 are fixedly connected to the opposite side of the two movable blocks 901.

[0023] The above solution is adopted: by setting the moving structure 9, when the mounting block 11 needs to be inserted into or removed from the inner cavity of the mounting groove 14, the moving structure 9 has a limiting effect on the movement position of the mounting block 11.

[0024] refer to Figure 4 The inner cavity of the fixed shell 7 is fixedly connected to two moving rods 10 that cooperate with the moving hole 902. The surface of the moving rod 10 is movably connected to the inner cavity of the moving hole 902.

[0025] The above solution is adopted: by setting the moving rod 10, when the mounting block 11 moves, it will drive the moving hole 902 to move along the surface of the moving rod 10. The cooperation between the moving hole 902 and the moving rod 10 has a limiting effect on the movement position of the mounting block 11.

[0026] refer to Figure 4 Each of the two movable blocks 901 has a mounting block 11 fixedly connected to its opposite side. The opposite sides of the two mounting blocks 11 penetrate the fixed shell 7 and extend to the outside of the inner cavity of the fixed shell 7.

[0027] The above solution is adopted: by setting the mounting block 11, when the fixed shell 7 moves into the inner cavity of the fixed shell 6, the control block 8 is released, and the restoring force generated by the spring 903 returning to its shape will drive the mounting block 11 to be inserted into the inner cavity of the mounting groove 14. The cooperation between the mounting block 11 and the mounting groove 14 has a limiting effect on the position of the fixed shell 7.

[0028] refer to Figure 4 The surface of the moving block 901 is provided with an extrusion hole 12. The control block 8 is fixedly connected to the side of the carriage 1 with an extrusion frame 13 that works with the extrusion hole 12. The surface of the extrusion frame 13 is movably connected to the inner cavity of the extrusion hole 12.

[0029] The above scheme is adopted: by setting the extrusion hole 12 and the extrusion frame 13, when the control block 8 rotates, it will drive the extrusion frame 13 to rotate along the inner cavity of the extrusion hole 12. The extrusion force generated by the extrusion frame 13 on the extrusion hole 12 can drive the two moving blocks 901 to move.

[0030] refer to Figure 3 The inner cavity of the fixed housing 6 is provided with a mounting groove 14 that is used in conjunction with the mounting block 11, and the surface of the mounting block 11 is in contact with the inner cavity of the mounting groove 14.

[0031] The above solution is adopted: by setting the mounting groove 14, when the tarpaulin 4 completely covers the vehicle body 1, the mounting block 11 is moved into the inner cavity of the mounting groove 14. The cooperation between the mounting block 11 and the mounting groove 14 has a limiting effect on the position of the tarpaulin 4.

[0032] refer to Figure 2 The inner cavity of the movable frame 2 is movably connected with several movable sliders 15. The bottom of the tarpaulin frame 3 is fixedly connected to the movable sliders 15 and the top of the fixed block 5. The top of the fixed shell 7 is fixedly connected to the bottom of the movable sliders 15.

[0033] The above solution is adopted: by setting a movable slider 15, when the tarpaulin frame 3 moves, it will drive the movable slider 15 to move along the inner cavity of the movable frame 2. The cooperation between the movable slider 15 and the movable frame 2 has a limiting effect on the movement position of the tarpaulin frame 3 and the tarpaulin 4.

[0034] The working principle of this utility model:

[0035] In use, when the cargo box 1 of the road freight transport vehicle needs to be conveniently covered, the user first places the cargo inside the box, then rotates the control block 8. When the control block 8 rotates, it will cause the compression frame 13 to rotate along the inner cavity of the compression hole 12. The compression hole 12, subjected to compression force, will cause the two moving blocks 901 to move closer to each other. When the moving blocks 901 move, they will cause the moving hole 902 to move along the surface of the moving rod 10. The force generated when the moving blocks 901 move causes the spring 903 to elastically deform. When the moving blocks 901 move, they will cause the two mounting blocks 11 to move closer to each other. When the mounting blocks 11 move into the inner cavity of the fixed shell 7, they will move backward. Pulling the fixed shell 7 will cause the movable slider 15 to move along the inner cavity of the movable frame 2. When the movable slider 15 moves, it will cause the tarpaulin frame 3 and the tarpaulin 4 to move backward. When the fixed shell 7 moves into the inner cavity of the fixed clip 6 and the tarpaulin 4 completely covers the truck bed 1, the control block 8 is released. The restoring force generated by the spring 903 returning to its shape will cause the mounting clip 11 to be inserted into the inner cavity of the mounting groove 14. The cooperation of the mounting clip 11 and the mounting groove 14 has a limiting effect on the position of the fixed shell 7, the movable slider 15 and the tarpaulin frame 3. The setting of the tarpaulin frame 3 and the tarpaulin 4 has a shielding effect on the goods transported by the truck bed 1. At this time, the truck bed 1 for road freight transport completes the convenient covering of the transported goods.

[0036] In summary, this road freight transport vehicle box covering device, through the coordinated use of the movable structure 9, movable block 901, movable hole 902, spring 903, and mounting clip 11, solves the problem that existing road freight transport vehicles face high wind resistance when traveling on highways, making uncovered goods easily blown off by the wind. Furthermore, goods are susceptible to external environmental factors such as wind, rain, and dust, and some goods require sun protection. Therefore, tarpaulins are needed to cover the cargo box during road freight transport. Existing tarpaulins require multiple ropes for fixation, which have poor stability. If the ropes break, goods can easily fall, potentially causing traffic safety hazards. Moreover, the installation and removal of ropes are time-consuming and inconvenient. However, existing road freight transport vehicles lack components for conveniently covering transported goods.
