Description

Technical Field

[0001] This utility model belongs to the field of plastic pallet technology, specifically relating to a stackable plastic pallet. Background Technology

[0002] Pallets are indispensable in the logistics industry. The advantages of plastic pallets are: light, stable, beautiful, good integrity, nail-free and splinter-free, odorless and non-toxic, acid-resistant, alkali-resistant, corrosion-resistant, easy to clean and disinfect, non-rotting, and recyclable. They are important tools for modern transportation, packaging, and warehousing, and are internationally recognized as essential equipment for the storage of food, aquatic products, pharmaceuticals, chemicals, and other industries.

[0003] A review of the publicly disclosed (announcement) number CN212048343U reveals a plastic pallet. This technology discloses technical solutions such as "including a pallet body, with multiple legs integrally fixed on one side of the pallet body, and reinforcing strips inserted inside the pallet body to enhance the load-bearing strength of the pallet body; enhancing the load-bearing strength of the pallet body; and effectively preventing the reinforcing strips from detaching from the pallet due to the anti-slip plugs at both ends of the reinforcing strips."

[0004] However, during use, plastic pallets often need to be lifted by forklifts. When multiple sets of plastic pallets are placed together, they are not easily stacked together. Furthermore, during forklift transportation, the pallets are only secured by increasing friction, which is not enough to make them securely attached. This makes the plastic pallets easy to separate and fall.

[0005] To address these issues, we propose a stackable plastic tray. Utility Model Content

[0024] Please see Figures 1-5 This utility model provides a stackable plastic tray, including a tray body 1 and a plurality of support legs 2 uniformly and fixedly connected to the bottom surface of the tray body 1. A plurality of limiting grooves 3 are uniformly opened on the surface of the tray body 1 at the position of the support legs 2, and the support legs 2 are inserted into the limiting grooves 3. A plurality of inserts 5 are uniformly and fixedly connected to the surface of the tray body 1, and each insert 5 is located inside the limiting groove 3. A limiting groove 4 is opened at the end of the support leg 2 away from the tray body 1, and the insert 5 is inserted into the limiting groove 4.

[0025] In this embodiment, a plurality of positioning holes 10 are evenly provided inside the tray body 1. Each positioning hole 10 is provided with a positioning rod 8. The positioning rod 8 is fixedly connected to the tray body 1. A positioning cylinder 7 is slidably connected to the surface of the positioning rod 8. A positioning plate 6 is provided inside the limiting groove 3. The positioning plate 6 is fixedly connected to the positioning cylinder 7. A spring A9 is provided inside the positioning hole 10. The two ends of the spring A9 are fixedly connected to the tray body 1 and the positioning cylinder 7, respectively.

[0026] In this embodiment, the support leg 2 has a sliding groove A11 inside, and a limit block C13 is provided inside the sliding groove A11. The limit block C13 is slidably connected to the support leg 2 through the sliding groove A11. A spring B12 is provided inside the sliding groove A11, and the two ends of the spring B12 are fixedly connected to the limit block C13 and the support leg 2 respectively.

[0027] In this embodiment, the limiting block C13 has a trapezoidal structure, and the inclined surface of the limiting block C13 faces the limiting groove 4. The insert block 5 has an umbrella-shaped structure, and the inclined surface of the limiting block C13 and the arc surface of the insert block 5 fit together.

[0028] In this embodiment, the positioning block C13 has a positioning groove 14 inside, and two positioning blocks A15 are symmetrically fixedly connected inside the positioning groove 14. Two positioning blocks B16 are symmetrically arranged inside the positioning groove 14. The support leg 2 has a sliding groove B17 inside, and a pull plate 18 is arranged inside the sliding groove B17. The pull plate 18 is slidably connected to the support leg 2 through the sliding groove B17. One end of the pull plate 18 is inserted into the positioning groove 14 and is fixedly connected to the positioning block B16. A pull rod 19 is arranged on one side of the support leg 2. The pull rod 19 is rotatably connected to the pull plate 18 through a bearing.

[0029] In this embodiment, both the limiting block A15 and the limiting block B16 are triangular structures, and the inclined surfaces of the limiting block A15 and the limiting block B16 fit together. The width of the pull plate 18 is narrower than the distance between the two limiting blocks A15.

[0030] The working principle of this utility model is as follows: When stacking pallet bodies 1, one pallet body 1 is placed in the stacking area, and then another pallet body 1 is placed on the upper surface of the first pallet body 1. The upper support leg 2 is then inserted into the lower limiting groove 3. The limiting groove 3 limits the support leg 2, enhancing the stability between the pallet bodies 1 and the pallet body 1 during stacking. When the support leg 2 is inserted into the limiting groove 3, the upper support leg 2 contacts the lower positioning plate 6 and presses against it. The positioning cylinder 7 connected to the positioning plate 6 moves towards the positioning hole 10 on the surface of the positioning rod 8. The positioning plate 6 moves downwards inside the limiting groove 3, facilitating the insertion of the support leg 2 into the limiting groove 3. When the positioning plate 6 is not pressed, it is flush with the upper surface of the pallet body 1 due to the elastic potential energy of the spring A9. This ensures that the surface of the pallet body 1 remains flat and aesthetically pleasing when large objects are placed on it. When the support leg 2 is inserted into the limiting groove... At time 3, the insert block 5 will be inserted into the limiting groove 4. When the insert block 5 is inserted into the limiting groove 4, the limiting block C13 will be squeezed by the insert block 5 and slide inside the slide groove A11. The spring B12 will be compressed and deformed until the insert block 5 passes the limiting block C13. Then, the elastic potential energy of the spring B12 will cause the limiting block C13 to return to its original position. The shape of the insert block 5 and the limiting block C13 limits the support leg 2, thereby fixing the pallet body 1 during stacking and making the stacking more stable. When the pallet body 1 needs to be removed, force is applied to the pull rod 19 to lift it upwards. The pull plate 18 will be under force and slide inside the slide groove B17. The limiting block B16 connected to the pull plate 18 applies force to the limiting block A15. The shape of the limiting block A15 and the limiting block B16 causes the limiting block C13 to slide inside the slide groove A11 until the limiting block C13 releases its limiting on the insert block 5. Then the pallet body 1 can be removed from the other surface, which facilitates the picking and putting away of the pallet body 1.
