Description

Technical Field

[0001] This utility model relates to the field of pallet technology, and in particular to a lightweight pallet. Background Technology

[0002] A pallet is a horizontal platform device used for containerizing, stacking, handling, and transporting goods. It transforms static goods into dynamic goods. Pallets are lightweight, reducing extra weight during transport; they are easy to return empty, saving return transport costs and space; they are easy to load, facilitating the sorting and securing of goods; when using pallets as the transport unit, the number of freight items decreases while the volume and weight increase, and each pallet holds the same quantity, facilitating counting, sorting, and handover, reducing cargo discrepancies. Metal pallets are mainly made of steel and aluminum alloy, plastic pallets are made of plastic through injection molding or blow molding, wooden pallets are made of wood, and composite material pallets are made of two or more materials.

[0003] Chinese Patent Publication No. CN222330267U discloses a lightweight plastic pallet, comprising a pallet base and a pallet body. The pallet base includes symmetrically arranged support plates, with two storage grooves on the end faces of the symmetrically arranged support plates that are close to each other. Multiple folding connecting components connect the symmetrically arranged support plates. The pallet body includes a frame, and multiple support rods are arranged inside the frame. This utility model is lightweight, easy to handle, and can be folded up to reduce space occupation when not in use. When in use, this device has good pressure resistance and support.

[0004] For existing lightweight pallets, in actual use, the pallets themselves have no means of movement and can only be moved with the help of forklifts or handcarts, making it very difficult to move the pallets in narrow spaces. During transportation, the goods are directly exposed to the outside and are easily damaged by collisions and shaking. The goods are also corroded by natural factors such as rain, snow, wind and sand, resulting in a decline in quality. Utility Model Content

[0005] The purpose of this invention is to provide a lightweight pallet that solves the problems of existing pallets being unable to move freely in narrow spaces and goods being easily exposed and damaged.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lightweight pallet includes a chassis with four rotating slots at the bottom. A mounting plate is fixedly connected inside the rotating slots. A roller frame is provided at the bottom of the mounting plate via an ejection mechanism. Four T-shaped insertion slots are provided at the top of the chassis. Side plates are slidably connected inside the insertion slots. A top plate is provided between the tops of the four side plates. Anti-detachment mechanisms are provided between adjacent side plates and the top plate. Corner blocks are fixedly connected between the four side plates by bolts.

[0008] Preferably, the ejection mechanism includes a groove formed at the bottom of the mounting plate, and two quadrilateral support frames are provided inside the groove. The two support frames are rotatably connected, and a stabilizing plate is provided between the bottoms of the two support frames. The stabilizing plate is fixedly connected to the top of the roller frame.

[0009] Preferably, one end of the two support frames located on the same side is rotatably connected to the mounting plate and the stabilizing plate, respectively. The top of the stabilizing plate is provided with an auxiliary groove, and one end of the two support frames located on the same side is slidably connected to the inside of the sliding groove and the auxiliary groove, respectively.

[0010] Preferably, the mounting plate has a threaded connection to a screw on its side, and an auxiliary sleeve is fitted on the surface of the screw. The auxiliary sleeve is rotatably connected to the adjacent support frame, and one end of the screw is threaded to the side of the slide groove.

[0011] Preferably, the anti-detachment mechanism includes mounting blocks fixedly connected to both sides and the top of the side plate and the surface of the top plate, with anti-detachment blocks slidably connected between two adjacent mounting blocks.

[0012] Preferably, one end of the screw passes through the side of the chassis, and a threaded sleeve is connected to one end of the screw.

[0013] This utility model has the following beneficial effects:

[0014] When using the chassis to transport goods, the roller frame can be pushed out by turning the screw, raising the chassis. The rollers on the roller frame can then be used to easily move the chassis, facilitating the transport of goods. During transport, the side panels and top panel can be assembled to cover the goods, preventing them from falling off the chassis and protecting them from external damage. This ensures safe and convenient transport of goods on the chassis. Attached Figure Description

[0022] 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. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-5A lightweight tray includes a base 1. The bottom of the base 1 has four rotating grooves 2. A mounting plate 3 is fixedly connected inside the rotating grooves 2. A roller frame 5 is mounted on the bottom of the mounting plate 3 via an ejection mechanism 4. When items placed on the base 1 need to be moved, the ejection mechanism 4 ejects the roller frame 5 out of the mounting groove, and the rollers on the roller frame 5 facilitate movement of the base 1. Thus, the mounting plate 3 can fix the ejection mechanism 4 and the roller frame 5 inside the rotating grooves 2, and can be easily removed when not in use. The top of the base 1 has four T-shaped insertion slots 6. Side plates 7 are slidably connected inside the insertion slots 6. After items are placed on the base 1, the four side plates 7 can be fixed to the base 1 via the insertion slots 6. On the pallet 1, a top plate 8 is provided between the tops of the four side plates 7 to cover the items. The top plate 8 works with the side plates 7 to completely cover the items on the pallet 1, thus protecting the items during transportation and preventing them from falling and being damaged due to collisions or shaking. An anti-detachment mechanism 9 is provided between adjacent side plates 7 and top plate 8. The side plates 7 and top plate 8 are fixedly connected to each other through the anti-detachment mechanism 9 to prevent the side plates 7 and top plate 8 from becoming unstable during transportation and causing items to fall out, thus ensuring the safety of the items. Corner blocks 10 are fixedly connected between the four side plates 7 by bolts. The four corner blocks 10 can assist in the stability of the four side plates 7 and top plate 8, so that the items on the pallet can be transported more safely.

[0024] Furthermore, the ejection mechanism 4 includes a chute 401 formed at the bottom of the mounting plate 3. Inside the chute 401 are two quadrilateral support frames 402, which are rotatably connected. A stabilizing plate 403 is provided between the bottoms of the two support frames 402. The stabilizing plate 403 is fixedly connected to the top of the roller frame 5. When the rollers in the roller frame 5 are needed to move the chassis 1 to transport items, the roller frame 5 can be easily ejected from the inside of the rotating groove 2 by the cross distribution of the two support frames 402, thereby raising the height of the chassis 1 and facilitating the movement of the chassis 1 by the rollers on the roller frame 5. The stabilizing plate 403 fixes the roller frame 5 to the ejection mechanism 4. When not in use, they can be disassembled and placed separately. The relative proximity and distance of the tops of the two support frames 402 in the chute 401 can control the roller frame 5 to leave and enter the rotating groove 2.

[0025] Furthermore, one end of each of the two support frames 402 on the same side is rotatably connected to the mounting plate 3 and the stabilizing plate 403, respectively. The top of the stabilizing plate 403 is provided with an auxiliary groove 404. One end of each of the two support frames 402 on the same side is slidably connected to the inside of the slide groove 401 and the auxiliary groove 404, respectively. When the roller frame 5 is controlled by the two support frames 402 approaching and separating, one side of each of the two support frames 402 is fixed to a point on the mounting plate 3 and the stabilizing plate 403 and rotates. At this time, the free ends of the two support frames 402 can slide inside the slide groove 401 and the auxiliary groove 404, but the free ends of the two support frames 402 cannot detach from the slide groove 401 and the auxiliary groove 404, so that the two support frames 402 provide relatively stable support for the chassis 1, thereby facilitating the ejection of the roller frame 5 out of the rotating groove 2 for use.

[0026] Furthermore, a screw 405 is threadedly connected to the side of the mounting plate 3. An auxiliary sleeve 406 is fitted onto the surface of the screw 405. The auxiliary sleeve 406 is rotatably connected to the adjacent support frame 402. One end of the screw 405 is threadedly connected to the side of the slide groove 401. When it is necessary to push out the roller frame 5, the screw 405 can be rotated. The screw 405 is threadedly connected to the side of the slide groove 401 and moves away from the slide groove 401 during rotation. At this time, the auxiliary sleeve 406 can move with the screw 405 and rotate on the screw 405. This ensures that the auxiliary sleeve 406 moves one end of the support frame 402 without interference. The rotation of the screw 405 drives the support frame 402 to move, thereby bringing the two support frames 402 closer together to push the roller frame 5 out of the rotating groove 2 for use.

[0027] Furthermore, the anti-detachment mechanism 9 includes mounting blocks 901 fixedly connected to the sides and top of the side plate 7 and the surface of the top plate 8. An anti-detachment block 902 is slidably connected between two adjacent mounting blocks 901. When it is necessary to assemble the side plate 7 and the top plate 8, the two adjacent mounting blocks 901 can be fixed together by the anti-detachment block 902 so that the side plate 7 and the top plate 8 will not easily separate. The end of the mounting block 901 near the anti-detachment block 902 is T-shaped. The anti-detachment block 902 surrounds one end of the mounting block 901 with an internal T-shaped frame, and then fixes the frames surrounding the two adjacent mounting blocks 901 with an L-shaped connecting block, so that the two adjacent mounting blocks 901 are fixed together by the anti-detachment block 902.

[0028] Furthermore, one end of the screw 405 passes through the side of the chassis 1, and a threaded sleeve 407 is threaded onto one end of the screw 405. The location of one end of the screw 405 on the side of the chassis 1 facilitates operation. After the screw 405 is adjusted, the threaded sleeve 407 is then fitted onto the screw 405 to prevent the screw 405 from moving easily and to ensure the stability of the screw 405.

[0029] In summary:

[0030] When using the pallet, first place the goods on top of the chassis 1, then insert the four side plates 7 into the insertion slots 6, and place the top plate 8 on top of the four side plates 7. Next, use the anti-detachment block 902 to fix adjacent mounting blocks 901 together, ensuring the stability of the side plates 7 and top plate 8. This allows the side plates 7 and top plate 8 to stably cover the items on the chassis 1. Then, use the corner block 10 to cover the corners of the side plates 7, further improving the stability of the side plates 7 and top plate 8. When moving the chassis 1, a forklift can be used directly through the forklift bay at the bottom of the chassis 1. If no forklift is available, remove the nut 407 before placing the goods on the chassis 1, then rotate the screw 405. The screw 405 rotates inside the slide groove 401, causing it to move outwards. Then, put the nut 407 back onto the screw 405. The movement of the screw 405 drives the auxiliary sleeve 406 to move, which in turn moves the auxiliary sleeve 406. One support frame 402 moves along with the other, bringing one support frame 402 closer to the other. The two support frames 402 are distributed in an interlaced manner. When they are close together, the roller frame 5 at the bottom of the stabilizing plate 403 can be pushed downward out of the rotating groove 2, so that the rollers on the roller frame 5 can rotate and drive the chassis 1 to move. The sliding groove 401 inside the mounting plate 3 and the auxiliary groove 404 inside the stabilizing plate 403 restrict the support frame 402, preventing the support frame 402 from detaching from the sliding groove 401 and the auxiliary groove 404, which would cause changes in angle and affect use. With the above structure, when it is necessary to transport items on the chassis 1, the items can be easily covered by the side plate 7 and the top plate 8 to prevent the goods from being directly exposed to the outside. During transportation, the goods are prone to falling and being damaged due to collisions and shaking. The goods are also protected from being corroded by natural factors such as rain, snow, and sand, which would lead to a decrease in quality. Furthermore, the rollers on the roller frame 5 can be easily pushed out of the rotating groove 2 to drive the chassis 1 to move.
