Description

Technical Field

[0001] The utility model relates to the technical field of plastic pallet structures, and particularly relates to a flat Sichuan-shaped plastic pallet with a clamping function. Background Art

[0002] Plastic pallets are used for facilitating the loading, unloading, transportation, storage, and distribution of goods. They are mainly composed of several pallet boards of different sizes. The flat Sichuan-shaped plastic pallet is one type of plastic pallet, with three crossbeams arranged at the bottom of the pallet, and its shape is similar to the Chinese character 'Chuan' (river). In the unified national standard, it is named the 'Chuan' character pallet. For example, the existing flat Sichuan-shaped plastic pallet with the publication number CN202481455U has an integrally formed tray surface and tray bottom. Each tray bottom internally has a tray bottom steel pipe placed along the length direction, and four tray surface steel pipes are evenly arranged inside the tray surface. It has a certain bearing capacity, but the binding force on the items placed on the tray surface during transportation is relatively poor, and the items often easily slide off the pallet during transportation, which is not conducive to the development of production and transportation work. Content of the Utility Model

[0003] Aiming at the defect that the existing flat Sichuan-shaped plastic pallet has a relatively poor binding force on the items placed on the tray surface and the items are likely to slide off the tray surface during transportation, the utility model provides a flat Sichuan-shaped plastic pallet with a clamping function, which can provide a strong binding force on the items placed on the tray surface, and the items are not easy to slide off the pallet.

[0004] The utility model provides the following technical solutions:

[0005] It includes a tray seat and a tray. Compression springs are installed in parallel on the surface of the tray seat, and the tray seat is connected to the tray through the compression springs. Its characteristics are as follows: The tray is installed in the tray seat to form a height difference. The inner wall of the longer side of the tray seat directly limits and fixes the items, and extrusion blocks are installed on both sides of the tray. Corresponding to the extrusion blocks, clamping blocks are arranged inside the tray seat. The inclined surfaces at the lower ends of the clamping blocks are closely fitted with the inclined surfaces of the extrusion blocks. When the tray moves downward, it drives the extrusion blocks to rotate the clamping blocks to fixedly clamp the items.

[0006] Its further characteristics are as follows:

[0007] The tray and the tray seat are respectively installed with frustum cones and rings, and the frustum cones are sleeved with each other;

[0008] The extrusion blocks are installed on the fixed seats through rotating rollers, and the fixed seats are installed on the inner wall of the tray seat;

[0009] The tray seat is fixedly connected to the tray bottom through a heightening block. The tray bottom is arranged in a 'Chuan' character shape below the tray seat, and steel pipes are installed in parallel inside the tray bottom.

[0010] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0011] The pallet is installed inside the pallet seat to form a height difference so that the inner wall of the pallet seat can limit the two sides of the items. The pallet is connected to the pallet seat through a compression spring, making the pallet movable. When the items are placed on the pallet, the extrusion block of the pallet moves downward, causing the clamping block to rotate to clamp and fix the other two sides of the items. The items are fixed circumferentially to form a strong constraint, which is not easy to slip during transportation, which is conducive to the development of enterprise transportation work.

[0012] The pallet seat is connected to the bottom support through the spacer block. The spacer block can increase the stability of the overall structure. The bottom support installed with steel pipes has enhanced rigidity, ensuring that the items can be transported stably on the pallet.

[0013] The setting of the frustum and the ring enables the tray to remain stable as a whole without shaking. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The utility model provides Figure 1 The present invention shows a flat, Sichuan-shaped plastic pallet with a clamping function, which includes a pallet seat 2 and a pallet 1. Compression springs 9 are installed in parallel on the surface of the pallet seat 2. The pallet seat 2 is connected to the pallet 1 through the compression spring 9. The pallet 1 is installed in the pallet seat 2 to form a height difference. The inner wall of the longer side of the pallet seat 2 directly limits and fixes the items. Extrusion blocks 3 are installed on both sides of the pallet 1. Clamping blocks 4 are provided inside the pallet seat 2 corresponding to the extrusion blocks 3. The inclined surface of the lower end of the clamping block 4 is tightly fitted with the inclined surface of the extrusion block 3 (see FIG. 1 ). Figure 8 ), when the tray 1 moves downward, it drives the squeezing block 3 to rotate the clamping block 4 to fix the article;

[0025] See Figure 5 、 Figure 6 , the tray 1 and the tray seat 2 are respectively equipped with a truncated cone 7 and a circular ring 8, and the truncated cone 7 and the truncated cone 8 are fitted into each other;

[0026] See Figure 3 , the extrusion block 3 is mounted on the fixed seat 5 through the rotating roller 6, and the fixed seat 5 is mounted on the inner wall of the tray seat 2;

[0027] See Figure 4 The tray seat 2 is fixedly connected to the bottom support 10 by the spacer block 11. The bottom support 10 is arranged in a "chuan" shape below the tray seat 2. Figure 7 A steel pipe 12 is installed parallel to the interior of the base 10 , and the installation of the steel pipe 12 increases the rigidity of the base 10 .

[0028] Working principle of this utility model:

[0029] Refer to the instruction manual Figures 1-8 When using this utility model, see Figure 2 When an item is placed on the tray 1, the tray 1 will move downward, and the squeezing block 3 will move downward synchronously to squeeze the clamping block 4. The clamping block 4 will be forced to rotate around the rotating roller 6, and the head of the clamping block 4 will move toward the item until the ring 8 and the frustum 7 fit together. At this time, the clamping block 4 just clamps the two sides of the item stably. Because of the height difference formed when the tray 1 is installed in the tray base 2, the inner wall of the tray base 2 directly fixes the other two sides of the item, so that the item can be transported more stably.
