Description

Technical Field

[0001] This utility model relates to the field of material pallet technology, specifically an adjustable pallet for material turnover. Background Technology

[0002] In modern logistics and transportation, as well as the internal material flow of various manufacturing enterprises, pallets play a crucial role as a fundamental and critical load-bearing tool. Pallets transform static materials into dynamic transportable units, greatly improving handling efficiency and ensuring the orderly flow of materials. They are widely used in warehousing, production workshops, and the connection between transport vehicles. From the storage and handling of goods in large warehousing centers to the movement of parts between different workstations on production lines, pallets are an important medium for achieving efficient logistics operations.

[0003] However, the material turnover pallets commonly available on the market have many limitations. On the one hand, the pallet bearing surface is not versatile enough. Most pallets have a single bearing surface design. For example, the common flat pallet is suitable for transporting goods with flat bottoms, but for goods with curved bottom corners, the contact surface is small and it is difficult to provide stable support. The goods are very easy to tip over during turnover, posing a great safety hazard. On the other hand, pallets with curved bearing surfaces and grooves are only suitable for goods of specific shapes and cannot be compatible with goods with flat bottoms. This leads to companies often needing to prepare multiple types of pallets to meet different goods needs when carrying out logistics transportation, which not only increases procurement costs but also wastes storage space. Utility Model Content

[0004] To address the existing technical problem that goods with curved bottom corners have a small contact surface, making them prone to tipping over during handling and posing a significant safety hazard, this utility model provides an adjustable pallet for material handling.

[0005] This utility model is achieved using the following technical solution: an adjustable pallet for material turnover, comprising a pallet body and a clamping plate, wherein the clamping plate is movably connected to the top of the pallet body, multiple slots are machined around the perimeter of the pallet body, a handwheel is provided at one end of the pallet body, a threaded rod is fixedly connected to one side of the handwheel, two threaded seats are threadedly connected to both ends of the threaded rod, a crossbar is fixedly connected to the top of the threaded seats, two hinge seats are fixedly connected to the top of the crossbar, the bottom of the clamping plate is hingedly connected to the top of the hinge seats, and two fixing strips are fixedly connected to one side of the clamping plate.

[0006] Preferably, a limiting post is fixedly connected to one side of the crossbar, and the top of the limiting post is located on one side of the clamping plate.

[0007] Preferably, one end of the clamping plate is machined with a groove.

[0008] Preferably, the pallet body has a movable groove machined inside, and the threaded seat is movably connected inside the movable groove.

[0009] Preferably, the top of the movable groove is machined with a connecting groove, and the crossbar is movably connected inside the connecting groove.

[0010] Preferably, two slots are machined at the bottom of one end of the connecting groove, and the fixing strip is plugged into the slot.

[0011] Preferably, the threaded rod has two threaded grooves machined at both ends, and the threads of the two threaded grooves are opposite.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In use, by flipping the two clamping plates upwards, the bottom ends of the clamping plates will rotate around the hinge seats, making the two clamping plates perpendicular to the pallet body. Then, by turning the handwheel, the handwheel will drive the threaded rod to rotate, which will drive the two threaded seats to move. The threaded seats will drive the crossbar to move, and the crossbar will drive the two clamping plates away from each other. After placing the material on the top of the pallet body, turning the handwheel will bring the two clamping plates closer together to clamp and support the bottom of the material, making it convenient to handle goods with curved bottom edges.

[0014] When in use, this utility model allows the clamping plate to be rotated so that it is placed in the connecting slot for storage. The two fixing strips will be inserted into the slots respectively, thereby switching to the conventional mode and making the top flat for handling conventional square materials.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Example 1: Please refer to Figure 1 - Figure 3 An adjustable pallet for material turnover according to this embodiment includes a pallet body 1 and a clamping plate 2. The clamping plate 2 is movably connected to the top of the pallet body 1. Multiple slots 3 are machined around the pallet body 1. A handwheel 4 is provided at one end of the pallet body 1. A threaded rod 5 is fixedly connected to one side of the handwheel 4. Two threaded seats 6 are threadedly connected to both ends of the threaded rod 5. A crossbar 7 is fixedly connected to the top of the threaded seat 6. Two hinge seats 8 are fixedly connected to the top of the crossbar 7. The bottom of the clamping plate 2 is hingedly connected to the top of the hinge seats 8. Two fixing strips 11 are fixedly connected to one side of the clamping plate 2.

[0021] When encountering goods with curved bottom corners and a small contact area with the pallet body 1, the two clamping plates 2 are flipped upwards. The bottom ends of the clamping plates 2 will rotate around the hinge seat 8, making the two clamping plates 2 perpendicular to the pallet body 1. Then, the handwheel 4 is turned, which will drive the threaded rod 5 to rotate. The threaded rod 5 will drive the two threaded seats 6 to move. The threaded seats 6 will drive the crossbar 7 to move. The crossbar 7 will drive the two clamping plates 2 away from each other. After the material is placed on top of the pallet body 1, the handwheel 4 is turned, and the two clamping plates 2 move closer to each other to clamp and support the bottom of the material, preventing the material from moving during the handling of the pallet body 1.

[0022] Secondly, by setting up the fixing strip 11, the contact area is increased. For materials with curved bottom corners (such as round barrels and curved bottom boxes), their surfaces are smooth and the natural contact area with the pallet is small. Simply relying on the flat clamping of the clamping plate can easily cause slippage due to "point contact". The fixing strip is a long strip structure that forms "line contact" when it comes into contact with the material. The contact area is increased by more than 40% compared to the direct clamping of the clamping plate. At the same time, through the superposition of friction, the risk of material slippage during handling is significantly reduced.

[0023] Furthermore, a limiting post 9 is fixedly connected to one side of the crossbar 7. The top of the limiting post 9 is located on one side of the clamping plate 2. A groove 10 is machined on one end of the clamping plate 2. By pulling the two clamping plates 2 upward through the groove 10, the bottom end of the clamping plate 2 rotates around the hinge seat 8 to a vertical state. Then, one side of the clamping plate 2 will contact the top of the limiting post 9, thereby limiting the clamping plate 2 through the limiting post 9 to prevent the clamping plate 2 from rotating at an angle greater than 90 degrees. At the same time, when the two clamping plates 2 clamp the material, the limiting post 9 limits the clamping plate 2 to clamp the material tightly.

[0024] Furthermore, the pallet body 1 has a movable groove 13 machined inside, and the threaded seat 6 is movably connected inside the movable groove 13. The threaded rod 5 has two threaded grooves machined at both ends, and the threads of the two threaded grooves are opposite. When the threaded rod 5 rotates and drives the threaded seat 6 to move, the threaded seat 6 will move along the inside of the movable groove 13, and the movable groove 13 will limit the movement of the threaded seat 6.

[0025] Furthermore, the top of the movable groove 13 is machined with a connecting groove 14, and the crossbar 7 is movably connected inside the connecting groove 14. When the threaded seat 6 drives the crossbar 7 to move, the crossbar 7 will move along the inside of the connecting groove 14, and the bottom of the clamping plate 2 will move along the inside of the connecting groove 14. By providing the connecting groove 14, the connecting groove 14 will limit the movement of the crossbar 7 and the clamping plate 2, so that the clamping plate 2 remains stable when it moves.

[0026] Furthermore, two slots 12 are machined at the bottom of one end of the connecting groove 14. The fixing strips 11 are plugged into the slots 12. When the clamp 2 is not needed, the clamp 2 is rotated to be stored in the connecting groove 14. The two fixing strips 11 on one side of the clamp 2 will be inserted into the slots 12 respectively, so that the normal mode can be switched. At this time, the pallet surface is flat and does not affect the placement of normal materials.

[0027] The fixing strip 11 is a rectangular strip with rounded corners at the ends to prevent jamming when inserted into the slot 12. When the clamp 2 is stored in a horizontal position, the fixing strip 11 is fully inserted into the slot 12. The slot 12 is equipped with a magnetic absorbing piece at the bottom, which can generate an adsorption force of 0.5N to prevent the clamp 2 from accidentally flipping out during transportation.

[0028] Working principle: By flipping the two clamping plates 2 upwards, the bottom ends of the clamping plates 2 will rotate around the hinge seat 8, making the two clamping plates 2 perpendicular to the pallet body 1. Then, turn the handwheel 4, which will drive the threaded rod 5 to rotate. The threaded rod 5 will drive the two threaded seats 6 to move. The threaded seats 6 will drive the crossbar 7 to move. The crossbar 7 will drive the two clamping plates 2 away from each other. After the material is placed on the top of the pallet body 1, turn the handwheel 4, and the two clamping plates 2 will move closer to each other to clamp and support the bottom of the material, making it convenient to handle goods with curved bottom corners.

[0029] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
