Description

Technical Field

[0001] The utility model relates to the field of plastic pallets, in particular to a convenient and practical plastic pallet. Background Art

[0002] A plastic pallet is a tray formed by palletizing packaging boxes containing items.

[0003] When stacking goods with existing plastic pallets, the situation of offset and misalignment often occurs at the bottom of the stack, resulting in more serious offset of the packaging boxes during the upward palletizing process, which leads to easy dumping of the palletized goods, and further increases the safety risk. Moreover, during the palletizing process, when the staff makes a palletizing offset, it is already very serious and requires re-palletizing, which is time-consuming. Content of the Utility Model

[0004] The purpose of the utility model is to provide a convenient and practical plastic pallet to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a convenient and practical plastic pallet, including a tray. At the four corners of the bottom end of the tray, there are fixedly connected bases, and two "return" shaped slots are symmetrically and fixedly connected to the bottom end of the tray. At the top end of the tray, there are two symmetrically connected fixing plates. On one side where the two fixing plates are close to each other, there is a groove with a cross-section in a rotated 90-degree "convex" shape. Inside the inner wall of the fixing plate, there is a sliding plate. At one end of the sliding plate and inside the tray, there is a fixing mechanism. At one end of the outer wall of the tray, there is a scale line;

[0006] The fixing mechanism is used to lock the position of the sliding plate. When the fixing mechanism is loosened, the sliding plate slides along the inner cavity of the fixing plate.

[0007] As a further scheme of the utility model: at both ends of the sliding plate, there are integrally formed vertical plates that penetrate to the outside of the fixing plate. Inside the fixing plate, there are limit slots for the thin shaft parts of the vertical plates to slide.

[0008] As a further scheme of the utility model: the fixing mechanism includes a connecting plate fixedly connected to one end of the outer wall of the vertical plate. There is a gap between the bottom end of the connecting plate and the bottom end of the tray. Inside the gap, there is a gasket. The top of the gasket is fixedly connected with a stud that penetrates above the connecting plate. The outer circumference of the stud is threadedly connected with a nut. The nut in the tightened state is used to press the connecting plate and the gasket.

[0009] As a further solution of the present utility model: A sliding shaft penetrating below the tray is integrally formed at the bottom end of the gasket, and a protruding portion is integrally formed at the bottom end of the sliding shaft. A sliding groove for axially sliding the sliding shaft is provided inside the tray.

[0010] As a further solution of the present utility model: Sliders that slide with the inner wall of the groove are formed at both ends of the sliding plate inside the groove of the fixed plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By providing a sliding plate and a fixing mechanism, the stacked packaging boxes at the bottom can be limited, avoiding the occurrence of palletizing deviation at the bottom of the packaging boxes, thereby reducing the probability of upward palletizing deviation. When the tray is not in use, the cooperation between the sliding plate and the fixing mechanism can also increase the connection force between the trays in the stacked state.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1 to 3, in the embodiment of the present utility model, a convenient and practical plastic tray includes a tray 1. At the four corners of the bottom end of the tray 1, there are fixedly connected bases 2, and symmetrically and fixedly connected at the bottom end of the tray 1 are two slots 3 in a "return" shape structure. At the top end of the tray 1, there are fixedly connected two symmetrically connected fixing plates 5. On one side of the two fixing plates 5 close to each other, there is a groove with a cross-section in a rotated 90-degree "convex" shape structure. Inside the inner wall of the fixing plate 5, there is a sliding plate 6 slidingly connected. At one end of the sliding plate 6 and inside the tray 1, there is a fixing mechanism. At one end of the outer wall of the tray 1, there is a scale line 9; the fixing mechanism is used to lock the position of the sliding plate 6, and when the fixing mechanism is loosened, the sliding plate 6 slides along the inner cavity of the fixing plate 5.

[0019] In this embodiment: First, when the tray 1 is not in use, a plurality of trays 1 are stacked vertically. After one tray 1 is stacked on another tray 1, by pulling the sliding plate 6 to slide inward until the sliding plate 6 that slides inward contacts the outside of the base 2, the two sliding plates 6 respectively clamp the outside of the four bases 2. After clamping, by tightening the fixing mechanism, the connection force between the trays 1 stacked up and down can be increased, achieving a more stable stacking effect.

[0020] When using the tray 1 and stacking items on the tray 1, generally the width of the packaging box is half of the length. By arranging them horizontally and vertically, the items can be stacked up and down and pressed against each other to achieve the stability of the items.

[0021] Therefore, when stacking and palletizing, after the packaging boxes at the bottommost layer are stacked, by pushing the two sliding plates 6 to move towards each other, the two sliding plates 6 moving towards each other clamp the two sides of the packaging boxes at the bottommost layer that have been stacked. After clamping, tighten the fixing mechanism again. The fixing mechanism fixes the position of the sliding plate 6 to achieve the purpose of restricting the packaging boxes at the bottommost layer, avoiding too large gaps between the packaging boxes at the bottommost layer and resulting in misalignment, and further avoiding the situation of the packaging boxes being offset and tilted during the process of gradually palletizing, thus facilitating the palletizing effect.

[0022] It should be noted that: The setting of the scale line 9 can ensure that the two sliding plates 6 are always in a symmetrical state after sliding.

[0023] Please refer to Figure 3 , at both ends of the sliding plate 6, there are integrally formed vertical plates 8 that penetrate to the outside of the fixing plate 5. Inside the fixing plate 5, there is a limiting groove 7 for the thin shaft part of the vertical plate 8 to slide.

[0024] In this embodiment: During the movement of the sliding plate 6, the movement of the sliding plate 6 drives the movement of the vertical plate 8, and the thin shaft part of the vertical plate 8 axially moves along the limiting groove 7.

[0025] Please refer to Figure 1 ,Figure 2 With Figure 3 , the fixing mechanism includes a connecting plate 10 fixedly connected to one end of the outer wall of the vertical plate 8. There is a gap between the bottom end of the connecting plate 10 and the bottom end of the tray 1. A gasket 11 is arranged in the gap. The top of the gasket 11 is fixedly connected with a stud 13 penetrating above the connecting plate 10. A nut 14 is threadedly connected to the outer periphery of the stud 13. The nut 14 in the tightened state is used to press the connecting plate 10 and the gasket 11.

[0026] In this embodiment: When the vertical plate 8 moves, the vertical plate 8 drives the connecting plate 10 to move synchronously. The moving connecting plate 10 drives the gasket 11 to move synchronously. After the sliding plate 6 moves to the preset position, the nut 14 is tightened. The tightened nut 14 presses the connecting plate 10 and the gasket 11. Since the connecting plate 10 is made of elastic plastic, after being pressed, the connecting plate 10 is slightly deformed and presses the gasket 11, thereby achieving the fixing effect and fixing the position of the sliding plate 6.

[0027] Please refer with emphasis to Figure 3 , a sliding shaft 12 penetrating below the tray 1 is integrally formed at the bottom end of the gasket 11. A protruding portion is integrally formed at the bottom end of the sliding shaft 12. A sliding groove 4 for the axial sliding of the sliding shaft 12 is opened inside the tray 1.

[0028] In this embodiment: During the sliding process of the gasket 11, the gasket 11 drives the sliding shaft 12 to move synchronously. The sliding shaft 12 axially slides along the sliding groove 4. After the nut 14 is tightened, the gasket 11 and the protruding portion of the sliding shaft 12 cooperate to fix the position of the sliding plate 6.

[0029] Please refer with emphasis to Figure 3 , sliding blocks that slide with the inner wall of the groove are formed at both ends of the sliding plate 6 located inside the groove of the fixing plate 5.

[0030] In this embodiment: When the sliding plate 6 slides, the sliding plate 6 drives the sliding blocks to slide in the groove. Both of them are in a "convex" shape structure, which can prevent the sliding blocks from detaching from the groove.

[0031] The above-mentioned is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
