[0002] A turnover pallet is a logistics tool used for storing, handling, and transporting goods. It is typically made of materials such as plastic, wood, or metal, and has a certain load-bearing capacity and stability. Turnover pallets are reusable, improving logistics efficiency and reducing logistics costs.
[0003] Waterproof and dustproof turnover pallets are containers used in logistics transportation and warehousing to carry goods and effectively prevent water and dust from entering. Their working principle mainly involves using a sealed design, such as sealing strips on the pallet edges, and using waterproof and dustproof materials to prevent water and dust from contacting the goods on the pallet, thereby protecting the goods from water damage and dust contamination.
[0004] Based on existing technology, some turnover pallets are difficult to move when loaded with goods, requiring manual disassembly and relocation, which is time-consuming, labor-intensive, increases labor costs, and can easily lead to fatigue. Therefore, a dustproof and waterproof turnover pallet is proposed to solve the above problems. Utility Model Content

Two sliding grooves are opened inside the top horizontal plate, and sliding rods are slidably connected inside the sliding grooves. A telescopic plate is fixedly connected to the bottom of the sliding rods. Locking plate frames are fixedly connected to the front and rear sides of the two fixed plates. Screws are threaded inside the locking plate frames. Baffles are fixedly connected to the left and right sides of the telescopic plate.
[0008] As a further description of the above technical solution: the adjacent sides of the plurality of gaskets are fixed to both sides of the limited slip frame, and the top of the limited slip frame is fixedly connected to the bottom of the bottom horizontal plate;
[0009] As a further description of the above technical solution: the upper and lower sides of the telescopic plate are slidably connected to the adjacent side of the two horizontal plates, and the bottom of the screw is in contact with the top of the baffle.
[0010] As a further description of the above technical solution: the tops of the plurality of storage racks are fixedly connected to the bottom of the fixing plate, and the tops of the plurality of storage racks are fixedly connected to the bottom of the bottom horizontal plate;

[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, when the handle is turned, the bidirectional threaded adjusting rod will drive the limiting ring and the sliding ring to move in opposite directions or back to back, thereby driving the transmission rod and the movable rod to move. The front side of the movable rod is fitted with a limiting slide frame, so that the movable rod moves inside it. The movable rod drives the retracting arm to move, thereby moving the pulley on the ground. In logistics transportation, this allows the pallet to be moved easily when carrying goods, saving manpower, improving transportation efficiency, optimizing warehouse management, and improving the overall smoothness of operations.
[0016] 2. In this utility model, the sliding rod moves within the sliding groove of the top horizontal plate, causing the telescopic plate to move laterally. As the telescopic plate moves, the baffle also moves accordingly. When the telescopic plate moves to the appropriate position, the telescopic plate can be fixed by tightening the screws, thereby improving the load-bearing capacity of the tray to meet the placement needs of items of different sizes, thus effectively saving costs.

[0023] 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.
[0024] Reference Figures 1 to 3This utility model provides an embodiment of a waterproof and dustproof turnover pallet. The bottom horizontal plate 1 has fixed strips 2 fixedly connected to both the front and rear sides. Rotating the handle 13 drives a bidirectional threaded adjusting rod 3 to rotate. Since the front and rear ends of the bidirectional threaded adjusting rod 3 are threadedly connected to limiting rings 4, its rotation causes the two limiting rings 4 to move towards or away from each other along the bidirectional threaded adjusting rod 3. A sliding ring 5 is rotatably connected to the front end of the limiting ring 4. The movement of the limiting ring 4 causes the sliding ring 5 to slide back and forth. The transmission rod 21, rotatably connected to both ends of the sliding ring 5, swings accordingly, then drives the transmission rod 6 to move via the transmission rod 21. The transmission rod 6 then pulls the movable rod 7 to slide within the sliding frame 8. The retractable arm 9, rotatably connected to the outside of the movable rod 7, expands or retracts. The pulley 10 at the other end of the retractable arm 9 rolls on the ground. Through the support and rolling of the pulley 10, the height of the pallet is adjusted. Telescopic components are fixed to both the left and right sides of the horizontal plate 1, facilitating the storage and handling of goods of different heights.
[0025] Reference Figure 1 and Figure 4 The telescopic assembly installed inside the horizontal plate 1 includes fixed plates 14 on the left and right sides, and two sliding grooves 15 inside the top horizontal plate 1. Sliding rods 16, slidably connected within the sliding grooves 15, can move freely within the grooves. Telescopic plates 17, fixedly connected to the bottom of the sliding rods 16, extend and retract vertically as the sliding rods 16 move, thus adjusting the lateral dimensions of the pallet. Locking brackets 18, fixedly connected to the front and rear sides of the two fixed plates 14, cooperate with baffles 20 fixedly connected to the left and right sides of the telescopic plates 17. When the telescopic plates 17 are adjusted to the appropriate position, screws 19 are screwed into the locking brackets 18 and pressed down, causing the bottom of the brackets to make tight contact with the top of the baffles 20, thereby fixing the position of the telescopic plates 17 and ensuring the stability of the pallet's lateral dimensions to meet the load-bearing requirements of goods of different specifications.
[0026] Reference Figures 2 to 4Multiple gaskets 12 are fixed on both sides of the limited-slip bracket 8 to cushion and reduce friction, protecting the sliding connection between the movable rod 7 and the limited-slip bracket 8. The top of the limited-slip bracket 8 is fixed to the bottom of the bottom horizontal plate 1, providing a sliding track and support for the movable rod 7. The upper and lower sides of the telescopic plate 17 are slidably connected to the two horizontal plates 1 to ensure the stability of the telescopic plate 17 during adjustment. The tops of multiple storage racks 11 are fixedly connected to the bottom of the fixed plate 14 and the bottom of the bottom horizontal plate 1, for storing loose items or auxiliary tools. The gaskets 12 on the outside of the movable rod 7 further reinforce the movable rod. 7. Stability and wear resistance at the connection with other components. The left and right ends of the telescopic plate 17 slide within the fixed plate 14 to ensure the accuracy of lateral telescopic extension. The near ends of multiple limited-slip brackets 8 are connected to the two ends of the fixed strip 2. When closed, the four baffles 20 contact the four locking plate brackets 18 and are fastened to the telescopic plate 17 with the screws 19. The top two ends of the transmission rod 6 are rotatably connected to the bottom of the bottom horizontal plate 1, serving as a transmission hub to transmit power. The retractable arm 9 slides within the limited-slip brackets 8, effectively improving the convenience and safety of goods storage and handling during logistics transportation and warehousing.
[0027] Working principle: When the pallet height needs to be adjusted, the operator rotates the handle 13 on the bidirectional threaded adjusting rod 3. When the handle 13 is rotated, the bidirectional threaded adjusting rod 3 will drive the two limiting rings 4 to move in opposite directions or away from each other outside. When the limiting rings 4 move, they will drive the transmission rod 21 to rotate through the sliding ring 5. The rotation of the transmission rod 21 will drive the transmission rod 6 and the movable rod 7 to move in sequence. The sliding bracket 8 sleeved on the front side of the movable rod 7 will limit the movable rod 7, so that it can only slide inside the sliding bracket 8. The sliding of the movable rod 7 will push the retracting arm 9 to move, thereby driving the pulley 10 to move on the ground, realizing the adjustment of the pallet pulley 10.
[0028] When it is necessary to expand the pallet's load-bearing area, the sliding rod 16 slides in the sliding groove 15 inside the top horizontal plate 1. The sliding of the sliding rod 16 will cause the telescopic plate 17 to slide up and down on the adjacent side of the two horizontal plates 1. As the telescopic plate 17 moves, the baffle 20 will also move accordingly. After the telescopic plate 17 is adjusted to the appropriate position, the screw 19 inside the locking plate frame 18 is turned. By tightening the screw 19, the telescopic plate 17 can be fixed in the corresponding position, thereby expanding the pallet's load-bearing area to meet the placement needs of items of different sizes.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
