Description

Technical Field

[0001] This utility model relates to the field of logistics transportation equipment technology, and more specifically, to a cargo anti-fall protection device for logistics transportation. Background Technology

[0002] Logistics and transportation is the physical flow of goods from the place of production to the place of consumption, encompassing transportation, warehousing, loading and unloading, and distribution. Its modes include road, rail, air, water and pipeline transportation. Modern logistics and transportation rely on information technology to improve transportation efficiency and reduce logistics costs by realizing full-process visualization and intelligent management. As a core link in the supply chain, logistics and transportation directly affect the speed and cost of commodity circulation and are crucial to economic development and global trade.

[0003] A search revealed a shock-absorbing logistics storage rack with publication number CN214493700U. This rack is designed to address the issue that vibrations can occur when it encounters collisions or bumps, and excessive vibrations can easily damage the rack and goods. By incorporating vertical plates, sliders, sliding rods, connecting rods, and sliding sleeves, the rack and goods are provided with shock absorption and cushioning.

[0004] However, while the above solution provides shock absorption and cushioning, the shelves and goods are still subject to vibration after the cushioning effect. This could cause the goods to fall off the sides of the shelves due to vibration, ultimately resulting in dents on the outer surface of the goods packaging or even damage to the goods themselves. Therefore, improvements are needed. Utility Model Content

[0009] As a preferred embodiment of this utility model, a plug is movably fitted onto the right surface of the L-shaped block, and the left end of the plug passes through the L-shaped block and the toothed plate in sequence and extends to the right surface of the shelf. The outer surface of the plug is movably connected to the inner surface of the first insertion hole. A pull handle is fixedly connected to the right end of the plug. A first spring is movably fitted onto the outer surface of the plug. The left end of the first spring is fixedly connected to the right surface of the L-shaped block, and the right end of the first spring is fixedly connected to the left surface of the pull handle.

[0010] As a preferred technical solution of this utility model, trapezoidal blocks are fixedly connected to the bottom ends of the outer surfaces on both sides of the shelf, and sleeve blocks are movably connected to the outer surfaces of the trapezoidal blocks. A second spring is fixedly connected to the bottom end of the inner surface of the sleeve block, the top end of the second spring is fixedly connected to the lower surface of the trapezoidal block, and a base plate is fixedly connected to the bottom end of the sleeve block.

[0011] As a preferred embodiment of this utility model, the bottom ends of the front and rear sides of the outer surface of the shelf are hinged with connecting rods, and the other end of the connecting rod is hinged with a slider.

[0014] This invention, by setting up a pressure plate, a connecting plate, a movable block, a driving rod, and a driven rod, allows the two movable blocks to move in opposite directions when the operator rotates the double-threaded rod. The movement of the movable blocks causes the driving rod to rotate, and the other end of the driving rod drives the driven rod to rotate as well. The other end of the driven rod then drives the connecting plate, causing the connecting plate and the pressure plate to move downwards. Finally, the pressure plate presses down on the upper surface of the goods packaging box, thus preventing the goods packaging box from moving inside the shelf and minimizing the possibility of goods falling due to vibration.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] like Figures 1 to 8 As shown, this utility model provides a cargo anti-fall protection device for logistics transportation, including a shelf 1, a pressure plate 2 movably connected to the inner surface of the shelf 1, a connecting plate 3 fixedly connected to the left end of the pressure plate 2, the outer surface of the connecting plate 3 movably connected to the inner surface of the shelf 1, a limiting frame 4 fixedly connected to the left surface of the shelf 1, two movable blocks 5 movably connected to the left and right sides of the inner surface of the limiting frame 4, an active rod 6 hinged to the right surface of each of the two movable blocks 5, a driven rod 7 hinged to the other end of the active rod 6, the other end of the driven rod 7 hinged to the left surface of the connecting plate 3, a double-threaded rod 8 movably installed on the front surface of the limiting frame 4, the other end of the double-threaded rod 8 passing through the limiting frame 4 and the movable blocks 5 in sequence and extending to the rear side of the limiting frame 4.

[0026] The rotation of the double-threaded rod 8 will cause the two moving blocks 5 to start moving in opposite directions. At this time, the driving rod 6 will start rotating as the moving blocks 5 move. The other end of the driving rod 6 will drive the driven rod 7 to start rotating as well. Finally, the other end of the driven rod 7 will drive the connecting plate 3, thereby causing the connecting plate 3 and the pressure plate 2 to start moving downward.

[0027] Among them, short baffles 9 are fixedly connected to the upper and lower sides of the left surface of the shelf 1, the right surface of the short baffles 9 is movably connected to the left surface of the connecting plate 3, and long baffles 10 are hinged to the outer surfaces of the front and rear sides of the shelf 1. A gear 11 located on the right side of the shelf 1 is fixedly connected to the right end of the long baffles 10.

[0028] The short baffle 9 is designed to block the opening on the left side of the shelf 1, while the long baffle 10 is designed to close the front and back sides of the shelf 1, preventing goods from falling to the outside of the shelf 1.

[0029] Among them, a toothed plate 12 is movably connected to the right surface of the shelf 1. A first insertion hole 30 is opened on the right surface of the toothed plate 12. A second insertion hole 31 is opened on the right surface of the toothed plate 12 below the first insertion hole 30. A limiting block 13 is movably connected to the right surface of the toothed plate 12. The left end of the limiting block 13 is fixedly connected to the right surface of the shelf 1. The outer surface of the toothed plate 12 is meshed with the outer surface of the gear 11. An L-shaped block 14 is movably connected to the lower side of the inner surface of the toothed plate 12. There are two L-shaped blocks 14. The left ends of the two L-shaped blocks 14 are fixedly connected to the right surface of the shelf 1.

[0030] Since gear 11 and toothed plate 12 mesh with each other, the downward movement of toothed plate 12 will drive gear 11, thereby causing gear 11 and long baffle 10 to start rotating as a whole. The limiting block 13 and L-shaped block 14 restrict the movement direction of toothed plate 12.

[0031] The right surface of the L-shaped block 14 is movably fitted with a plug 16. The left end of the plug 16 passes through the L-shaped block 14 and the toothed plate 12 and extends to the right surface of the shelf 1. The outer surface of the plug 16 is movably connected to the inner surface of the first insertion hole 30. The right end of the plug 16 is fixedly connected to a pull handle 15. The outer surface of the plug 16 is movably fitted with a first spring 17. The left end of the first spring 17 is fixedly connected to the right surface of the L-shaped block 14, and the right end of the first spring 17 is fixedly connected to the left surface of the pull handle 15.

[0032] The design of the first spring 17 causes the pull handle 15 and the plug 16 to move automatically to the left along the inner surface of the L-shaped block 14 under the elastic force of the first spring 17. When the plug 16 is inserted into the first socket 30, the long baffle 10 will be in an unfolded state, which makes it convenient for the operator to place the goods into the shelf 1. When the plug 16 is inserted into the second socket 31, the long baffle 10 will close the shelf 1.

[0033] Among them, trapezoidal blocks 18 are fixedly connected to the bottom of the outer surfaces on both sides of the shelf 1, and sleeve blocks 19 are movably connected to the outer surface of the trapezoidal blocks 18. A second spring 20 is fixedly connected to the bottom of the inner surface of the sleeve block 19, the top of the second spring 20 is fixedly connected to the lower surface of the trapezoidal blocks 18, and a base plate 21 is fixedly connected to the bottom of the sleeve block 19.

[0034] The design of trapezoidal block 18 and socket block 19 allows the entire shelf 1 to move up and down only along the inner surface of socket block 19, while the design of spring 20 provides a buffering effect.

[0035] Among them, the bottom ends of the front and rear sides of the outer surface of the shelf 1 are hinged with connecting rods 26, and the other end of the connecting rods 26 is hinged with sliders 24. The lower surface of sliders 24 is movably connected to the upper surface of the base plate 21. The inner surface of sliders 24 is movably sleeved with fixed posts 23. The left and right ends of the outer surface of fixed posts 23 are fixedly sleeved with connecting plates 22. The bottom end of connecting plates 22 is fixedly connected to the upper surface of the base plate 21. The outer surface of fixed posts 23 is movably sleeved with springs 25. The outer end of springs 25 is fixedly connected to connecting plates 22, and the other end of springs 25 is fixedly connected to sliders 24.

[0036] The lower surface of the base plate 21 is equipped with moving wheels. When the base plate 21 encounters bumps during movement, the base plate 21 will start to move up and down. At this time, the connecting rod 26 will start to rotate with the movement of the base plate 21. The other end of the connecting rod 26 will drive the slider 24, so that the slider 24 will start to move along the outer surface of the fixed column 23.

[0037] Among them, a movable block 27 is fixedly connected to the lower surface of the shelf 1, and a hollow block 28 located below the shelf 1 is movably connected to the outer surface of the movable block 27. The bottom end of the hollow block 28 is fixedly connected to the upper surface of the base plate 21, and a No. 4 spring 29 is fixedly connected to the lower surface of the movable block 27. The bottom end of the No. 4 spring 29 is fixedly connected to the bottom end of the inner surface of the hollow block 28.

[0038] The design of movable block 27 and hollow block 28 restricts the overall movement direction of shelf 1, while the design of spring 29 buffers the overall movement of shelf 1, thereby reducing the impact of vibration on shelf 1.

[0039] Working principle and usage process of this utility model:

[0040] First, the operator places identical cargo boxes into the shelf 1 and rotates the double-threaded rod 8. As the double-threaded rod 8 rotates, the two moving blocks 5 move in opposite directions under the limit of the limiting frame 4. The movement of the moving blocks 5 causes the driving rod 6 to start rotating. At the same time, the other end of the driving rod 6 drives the driven rod 7 to start rotating as well. The other end of the driven rod 7 drives the connecting plate 3, which causes the connecting plate 3 and the pressure plate 2 to move downward. Finally, the pressure plate 2 presses down on the upper surface of the cargo box, thereby increasing the friction between the cargo and the shelf 1. This helps to prevent the cargo from falling out of the shelf 1 when it encounters bumps.

[0041] When the goods inside the shelf 1 are non-compressible, the operator pulls the handle 15 to disengage the plug 16 from the first socket 30. At this time, the long baffle 10 will rotate under the action of gravity and eventually fit against the outer surface of the front and rear sides of the shelf 1. The front and rear sides of the shelf 1 will be closed by the long baffle 10, and the plug 16 will automatically align with the second socket 31 and enter the inner surface of the second socket 31 under the elastic force of the first spring 17. At this time, the positions of the toothed plate 12, gear 11 and long baffle 10 will be fixed, thereby preventing the goods from falling out of the shelf 1.
