[0002] Plastic pallets are a type of logistics unit used in conjunction with logistics equipment such as forklifts and shelves. They can be used to store, load and transport goods. They are one of the indispensable logistics equipment in modern logistics warehousing. The emergence of plastic pallets is to meet the needs of environmental protection. Using plastic pallets instead of wooden pallets can reduce the best product for forest damage. It is an inevitable product to adapt to the development of the logistics industry. With the continuous strengthening of food safety concepts and the high hygiene requirements of the pharmaceutical industry, plastic pallets are favored and sought after by the food and pharmaceutical industries for their corrosion resistance, moisture resistance, rust resistance, insect resistance, and mildew resistance. In addition, plastic pallets have the characteristics of high load-bearing capacity and long service life, and are widely used in chemical, textile, manufacturing and other fields.

[0003] There are many types of logistics pallets on the market. Most of them adopt plastic pallet structure. Plastic pallets adopt injection molding method, which makes the structure of plastic pallets relatively simple and the size is unique. When the size of the goods exceeds the size of the pallet, pallets are often spliced ​​in reality to change the size of the pallet for transportation. However, some goods are actually only slightly larger than a single pallet. If two pallets are spliced, more space will be left on the pallet, resulting in space waste and easy occupation of factory space. In addition, since the plastic pallet is an integrated structure, when the disk surface of the plastic pallet is worn to a certain extent, it is difficult to disassemble and replace the disk surface alone, and the entire pallet structure can only be scrapped, resulting in waste. A solution to the above problems is proposed below. Utility Model Content

[0004] The purpose of the utility model is to provide a special pallet for logistics transportation, which solves the problems proposed in the above background technology that the existing pallets cannot be adjusted in size and the pallet is an integrated structure, so that the pallet surface cannot be replaced individually after being worn and can only be scrapped as a whole, causing waste.

DETAILED DESCRIPTION

[0021] See Figures 1 to 6As shown, a special pallet for logistics transportation includes a main plate 1 and sub-plates 2 installed on both sides of the main plate 1. The bottom of the main plate 1 and the sub-plate 2 are both fixedly installed with support legs 3. A plurality of slide grooves 4 are symmetrically opened on the two opposite side walls of the main plate 1. A slide plate 5 is slidably set in each slide groove 4. One end of the slide plate 5 passes through the slide groove 4 and is fixedly connected to the sub-plate 2. A cavity 6 is provided inside the main plate 1, and a driving component 7 is provided in the cavity 6 for pushing the slide plates 5 on both sides to slide. During actual use of the pallet, when the size of the goods is larger than the pallet, the driving component 7 can be started to push the slide plate 5 in the center to move to the two sides of the pallet. The slide plate 5 will push the sub-plate 2 to achieve displacement, thereby changing the size of the pallet. The slide plates 5 on the other two sides play the role of supporting the sub-plate 2, so that the pallet can be adjusted in size according to its own needs, which can better adapt to the transportation of goods.

[0022] The driving assembly 7 includes a gear 12 and two racks 13. A support rod is installed in the cavity 6. The gear 12 is rotatably set on the support rod. Two slide grooves are respectively opened on both sides of the cavity 6. The two racks 13 are slidably set in the two slide grooves, and the two racks 13 are engaged with the gear 12. The two racks 13 slide on both sides through the gear 12. The two racks 13 pass through the two sides of the cavity 6 and are fixedly connected to the slides 5 on both sides. A connecting hole 14 is opened on the top of the main plate 1 to communicate with the cavity 6. A bolt 15 is rotatably set in the connecting hole 14. The bottom of the bolt 15 is fixedly connected to the gear 12. When the slide plate 5 needs to be pushed to move, the bolt 15 can be rotated to drive the gear 12 to rotate. The rotation of the gear 12 will push the racks 13 on both sides to slide, and the rack 13 slides in the second slide groove. The rack 13 is limited by the second slide groove to facilitate the linear movement of the rack 13. The continuous movement of the rack 13 will push the slide plate 5 to move outside the main disk 1, and the slide plate 5 will push the sub-disk 2 to move outward to adjust the size of the tray.

[0023] The top of the main plate 1 is provided with several threaded holes 18 corresponding to the slide plates 5, and the top of each slide plate 5 is provided with a slide groove three 19, which corresponds to the top threaded hole 18. Slide grooves four are symmetrically provided on the two inner walls of the slide groove 14. One end of the slide plate 5 located in the slide groove 14 is a trapezoidal structure, and the two ends of the slide plate 5 are slidably arranged in the slide groove four. By setting one end of the slide plate 5 as a trapezoidal structure, the slide plate 5 is prevented from separating from the main plate 1 during continuous movement, so that the movement of the slide plate 5 can be limited. When the slide plate 5 pushes the auxiliary plate 2 to move to the specified position, a fixing bolt 15 can be installed on the top of the main plate 1. The fixing bolt 15 can realize the limited fixing of the slide plate 5. In the subsequent use process, the auxiliary plate 2 moves outward, and the bottom of the fixing bolt 15 will be located in the slide groove three 19. The setting of the slide groove three 19 facilitates better fixing of the slide plate 5.

[0024] Wear-resistant plates 8 are installed on the top of the main plate 1 and the auxiliary plate 2, and connecting parts 9 are provided between the wear-resistant plates 8 and the main plate 1 and the auxiliary plate 2. By installing the wear-resistant plates 8 on the top of the pallet, the wear-resistant plates 8 are in contact with the goods to improve the wear resistance of the pallet. The wear-resistant plates 8 can also be detachably installed through the connecting parts 9, so that if the wear-resistant plates 8 are worn after long-term use, the wear-resistant plates 8 can be replaced to achieve continued use of the pallet, without replacing the entire pallet, which reduces the cost of use.

[0025] The connecting piece 9 includes a plurality of clamping blocks 16 and grid-shaped assembly holes 17 opened on the top of the main disk 1 and the auxiliary disk 2. Each clamping block 16 is fixed on the bottom of the wear-resistant plate 8. The clamping block 16 is engaged with the grid-shaped assembly hole 17. The wear-resistant plate 8 is fixed to the top of the main disk 1 and the auxiliary disk 2 through the clamping block 16. The clamping plate is fixed on both sides of the bottom of the wear-resistant plate 8. During the installation of the wear-resistant plate 8, the clamping block 16 is matched with the grid-shaped assembly hole 17. The wear-resistant plate 8 is pressed down so that the clamping block 16 enters the grid-shaped assembly hole 17 to realize the installation of the wear-resistant plate 8. When the wear-resistant plate 8 needs to be replaced later, it is only necessary to push the wear-resistant plate 8 upward to separate the clamping block 16 from the grid-shaped assembly hole 17. The remaining grid-shaped assembly holes 17 that do not need to be assembled with the clamping block 16 have a weight-reducing effect, thereby reducing the weight of the pallet and facilitating the use of the pallet.

[0026] A card slot 10 is provided on both end surfaces of the main disk 1 and the auxiliary disk 2. An extension plate 11 can be installed on both the main disk 1 and the auxiliary disk 2 through the card slot 10. When the end surfaces of the main disk 1 and the auxiliary disk 2 need to be enlarged, an extension plate 11 of a suitable size can be selected to insert one end of the extension plate 11 into the card slot 10 to achieve connection between the main disk 1 and the auxiliary disk 2. The extension plate 11 and the top are consistent in height with the wear-resistant plate 8, so it is easy to use. Several threaded holes 18 that communicate with the card slot 10 are also provided on the top of the main disk 1 and the auxiliary disk 2. By installing bolts 15 in the threaded holes 18, the extension plate 11 can be further fixed to improve the stability of the extension plate 11.

[0027] A slot 20 is provided at the bottom of the leg 3, and a wear-resistant pad 21 is installed on the leg 3 through the slot 20. By installing the wear-resistant pad 21 at the bottom of the leg 3, the wear resistance of the leg 3 can be improved. When the wear-resistant pad 21 is worn due to long-term use, the wear-resistant pad 21 can be replaced so that the leg 3 can continue to be used.
