Description

Technical Field

[0001] This utility model relates to the field of plastic pallet technology, specifically a plastic pallet with a limiting effect. Background Technology

[0002] Pallets are a medium that transforms static goods into dynamic goods; they are a cargo-carrying platform, and a movable platform, or a mobile ground. Even goods that lose their flexibility when placed on the ground immediately gain mobility and become flexible, mobile goods once loaded onto a pallet, because goods loaded on a pallet are always in a ready-to-move state. This dynamic loading and unloading method using pallets as the basic tool is called palletizing. When using pallets to transfer goods, it is necessary to limit the goods to prevent them from falling during the transfer process. However, the current limiting technology is relatively simple, resulting in poor stability of the goods during the transfer process, which may lead to them falling.

[0003] For example, patent CN222224715U describes a plastic pallet with a limiting function, comprising a pallet, a transmission box fixedly connected to the left side of the pallet, a support platform at the bottom of the pallet, a lifting plate fixedly connected to the top of the support platform, a locking block above the lifting plate, and a through hole corresponding to the locking block at the top of the pallet. Through a limiting mechanism consisting of a top plate, telescopic rod, limiting cylinder, bottom plate, and spring, the lifting mechanism raises the lifting plate, causing the locking block to pass through the through hole, and then the goods... The device uses its own weight to push some of the locking blocks and the top plate downwards, allowing the unpressed blocks to limit the cargo and thus limit its movement. This allows some devices to limit irregularly shaped cargo. However, during the limiting process, the weight of the cargo itself is needed to press the locking blocks down, which means the cargo is in a floating state. When there is a bump, the cargo is very likely to move significantly, causing the remaining blocking blocks to retract and no longer be able to block the cargo. Furthermore, when the cargo is high, the limiting effect is limited, and there is still a risk of the cargo tipping over and shifting to the side.

[0004] Based on this, a plastic tray with a limiting effect is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] In one embodiment, such as Figures 1-4 As shown, a plastic pallet with a limiting effect includes a pallet body 1. Connecting blocks 11 are symmetrically fixedly connected to the side walls of the pallet body 1. A fixing rod 12 is fixedly connected to the top of the connecting blocks 11. A connecting plate 13 is fixedly connected to the side wall of the fixing rod 12. A baffle 14 is fixedly connected to the side wall of the fixing rod 12. A placement frame 15 is fixedly connected to the side wall of the pallet body 1. Four limiting mechanisms 2 are provided on the side wall of the pallet body 1. A positioning mechanism 3 is provided inside the fixing rod 12.

[0022] In this embodiment, by the cooperation of the limiting mechanism 2 and the positioning mechanism 3, goods of different heights can be effectively limited to prevent them from tilting and slipping.

[0023] In an optional embodiment, such as Figure 3 As shown, the limiting mechanism 2 includes a movable rod 21, an extension rod 22 is slidably connected inside the movable rod 21, and a fixed shaft 23 is rotatably connected inside the movable rod 21. The outer wall of the fixed shaft 23 is fixedly connected to the inner wall of the tray body 1. The movable rod 21 is rotated around the fixed shaft 23 as the center, so that the movable rod 21 drives the extension rod 22 to rotate synchronously. When the rotation is at an appropriate angle, the extension rod 22 is stretched, so that the extension rod 22 is close to the positioning rod 34.

[0024] In an optional embodiment, such as Figure 3 As shown, a sliding groove is opened inside the fixed shaft 23, and a sliding rod 24 is slidably fitted therein. One end of the sliding rod 24 is fixedly connected to a first spring 25. One end of the first spring 25 is fixedly connected to the inner wall of the sliding groove. One end of the sliding rod 24 is fixedly connected to a pull plate 26. Pulling the pull plate 26 causes the sliding rod 24 to move synchronously, which stretches the first spring 25. At the same time, the pull plate 26 causes the gear ring 27 to move synchronously, so that the gear ring 27 no longer meshes with the arc-shaped retaining tooth 29. Then the movable rod 21 can be rotated with the fixed shaft 23 as the center.

[0025] In an optional embodiment, such as Figure 3 As shown, the slide bar 24 is composed of a cylindrical segment and a rectangular segment, and the slide groove is adapted to the rectangular segment to prevent the slide bar 24 from coming out of the slide groove.

[0026] In an optional embodiment, such as Figure 3 As shown, a toothed ring 27 is fixedly connected to the side wall of the pull plate 26. An annular groove for accommodating the toothed ring 27 is provided on the movable rod 21. An arc-shaped locking tooth 29 engages with the outer wall of the toothed ring 27. The arc-shaped locking tooth 29 slides in conjunction with a groove provided in the movable rod 21. A lever 28 is fixedly connected to the side wall of the arc-shaped locking tooth 29. The lever 28 slides in conjunction with a groove provided on the movable rod 21. When the pull plate 26 is released, the lever 28 can be moved to drive the arc-shaped locking tooth 29 to slide synchronously, so that the position of the arc-shaped locking tooth 29 can be finely adjusted, allowing the arc-shaped locking tooth 29 to engage with the toothed ring 27, thereby restricting the toothed ring 27 and preventing the pull plate 26 from rotating. This ensures the stability of the movable rod 21, allowing it to stably limit and block the goods on the pallet body 1, preventing the goods from slipping.

[0027] In an optional embodiment, such as Figure 4As shown, the positioning mechanism 3 includes a threaded rod 31. The outer wall of the threaded rod 31 is rotatably connected to the inside of the fixed rod 12. A slider 32 is threadedly connected to the outer wall of the threaded rod 31. The outer wall of the slider 32 is slidably connected to a groove on the fixed rod 12. A sleeve 33 is fixedly connected to the side wall of the slider 32. The sleeve 33 is slidably connected to a guide rail groove on the connecting plate 13. According to the height of the goods, the threaded rod 31 is rotated, causing the slider 32 to move axially, which drives the sleeve 33 to move synchronously. The sleeve 33 drives the positioning rod 34 to move to a suitable height, and then the rotation of the threaded rod 31 can be stopped.

[0028] In an optional embodiment, such as Figure 4 As shown, a positioning rod 34 is slidably connected to a groove inside the sleeve 33. One end of the positioning rod 34 is fixedly connected to a second spring 35, and one end of the second spring 35 is fixedly connected to the inner wall of the groove. The positioning rod 34 has a threaded section away from the outer wall of the connecting plate 13, and a nut 36 is threadedly connected to the outer diameter of the threaded section. When the extension rod 22 approaches the positioning rod 34, the positioning rod 34 is pressed, causing the positioning rod 34 to retract into the sleeve 33, compressing the second spring 35, thereby removing the obstruction of the positioning rod 34 to the extension rod 22. Then, the extension rod 22 can continue to rotate. When the extension rod 22 is rotated to the appropriate position, under the action of the elastic force of the second spring 35, the positioning rod 34 passes through the corresponding opening on the extension rod 22. Then, the nut 36 is used to lock the outer threaded section of the positioning rod 34, thereby limiting and fixing the extension rod 22 and the positioning rod 34.

[0029] In an optional embodiment, such as Figure 4 As shown, the positioning rod 34 is T-shaped, and the groove on the sleeve 33 is adapted to the wider part of the positioning rod 34, so as to prevent the positioning rod 34 from coming out of the groove in the sleeve 33.

[0030] The above embodiment discloses a plastic pallet with a limiting effect. When limiting the goods on the pallet body 1, the threaded rod 31 is rotated according to the height of the goods, causing the slider 32 to move axially, which in turn moves the sleeve 33 synchronously. The sleeve 33 moves the positioning rod 34 to a suitable height, and then the rotation of the threaded rod 31 can be stopped. Then, the pull plate 26 is pulled, causing the slider 24 to move synchronously, stretching the first spring 25. Simultaneously, the pull plate 26 moves the gear ring 27 synchronously, so that the gear ring 27 no longer engages with the arc-shaped locking teeth 29. Then, the movable rod 21 is rotated about the fixed shaft 23, causing the movable rod 21 to drive the extension rod 22 to rotate synchronously. After rotating to an appropriate angle, the extension rod 22 is stretched, bringing it closer to the positioning rod 34. At the same time, the positioning rod 34 is pressed, causing it to retract into the sleeve 33, compressing the second spring 35, thereby canceling the position of the positioning rod 34. After the extension rod 22 is blocked, it can continue to rotate. When the extension rod 22 is rotated to the appropriate position, under the elastic force of the second spring 35, the positioning rod 34 passes through the corresponding opening on the extension rod 22. Then, the external thread section of the positioning rod 34 is locked by the nut 36, which can limit and fix the extension rod 22 and the positioning rod 34. When the pull plate 26 is released, the lever 28 can be moved to drive the arc-shaped locking tooth 29 to slide synchronously. The position of the arc-shaped locking tooth 29 can be finely adjusted so that the arc-shaped locking tooth 29 can mesh with the tooth ring 27, thereby limiting the tooth ring 27 and preventing the pull plate 26 from rotating. This ensures the stability of the movable rod 21, so that it can stably limit and block the goods on the pallet body 1 and prevent the goods from slipping. In summary, through the cooperation of the limiting mechanism 2 and the positioning mechanism 3, goods of different heights can be effectively limited to prevent them from tilting and slipping.

[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
