DETAILED DESCRIPTION

[0020] like Figure 1-5 As shown, a counterweight pallet that is easy to stack includes a load-bearing body 1, which is a cavity with an open bottom. Support legs 2 are fixedly connected to the bottom corners of the load-bearing body 1. The support legs 2 are symmetrically arranged in pairs. The load-bearing body 3 is fixedly connected to the middle of the opposite inner side walls of the load-bearing body 1. An adjustable counterweight mechanism 6 is rotatably connected between the load-bearing plate 3 and the inner upper wall of the load-bearing body 1. The support plate 5 is fixedly connected to the bottom of the load-bearing plate 3. The support plate 5 and the load-bearing plate 3 are symmetrically arranged. A cavity is formed between the two legs for the front shovel to extend into, and the limiting plates 4 are fixedly connected between the inner walls of the supporting legs 2 which are symmetrical on the same side. The limiting plates 4 are symmetrically arranged with the supporting plate 5 as the center. The upper wall of the load-bearing body 1 is used to carry goods. The cavity formed by the limiting plates 4 below the load-bearing body 1 and the load-bearing plate 3 and the supporting plate 5 is used to limit the insertion of the front shovel of the forklift. At the same time, the front shovel can also be limited by the opposite side walls of the support plate 5 and the supporting legs 2, thereby realizing the four-way fork transfer of the entire pallet, and the adjustable counterweight mechanism 6 is used to increase the transfer stability of the pallet.

[0021] like Figure 2-5As shown, in order to improve the transfer stability of the pallet as a whole, the pallet is stably contacted with the front shovel by increasing the counterweight. The adjustable counterweight mechanism 6 includes a connecting ring 1 7, a connecting ring 2 8, a limiting column 9, a counterweight rod 10, a counterweight block 11 and a positioning assembly 12. The connecting ring 1 7 is fixedly connected to the center of the upper wall of the load-bearing body 1, the connecting ring 2 8 is fixedly connected to the middle of the upper part of the load-bearing plate 3, and a gap is left between the connecting ring 1 7 and the connecting ring 2 8. The limiting column 9 is rotatably connected to the inside of the connecting ring 1 7 and the connecting ring 2 8, and the counterweight rod 10 passes through the side wall of the limiting column 9 and is slidably arranged on the connecting ring 1 7 and the connecting ring 2 8. The counterweight 11 is fixedly connected to both ends of the counterweight rod 10. A limit blind hole 13 is opened at the upper end of the counterweight 11. The positioning assembly 12 is arranged in the limit blind hole 13. The counterweight is added inside the load-bearing body 1. The limit column 9 rotates inside the connecting ring 1 7 and the connecting ring 2 8 and limits it to achieve counterweight in different directions. The counterweight rod 10 passes through the limit column 9 horizontally. The counterweight rod 10 and the counterweights 11 at both ends are slidably adjusted to achieve counterweights in different positions and distances, thereby improving the adjustability of the pallet during counterweighting. After adjustment, the counterweight 11 is positioned by the positioning assembly 12 to increase the stability of the counterweight.

[0022] In order to increase the positioning effect of the counterweight 11 and improve the counterweight stability of the pallet, the positioning assembly 12 includes a screw 14, a limiting piece 15, a support spring 16 and a friction block 17. The screw 14 passes through the bottom wall of the counterweight 11 and is arranged in the limiting blind hole 13. The screw 14 is threadedly connected to the counterweight 11. The limiting piece 15 is fixedly connected to the outer wall of the screw 14. The limiting piece 15 is located in the limiting blind hole 13. The support spring 16 is wound around the outer wall of the screw 14. One end of the support spring 16 It is fixedly connected to the upper wall of the limiting plate 15, and the friction block 17 is fixedly connected to the other end of the support spring 16. The upper wall of the friction block 17 frictionally fits with the inner upper wall of the load-bearing body 1. After adjusting the counterweight rod 10 and the counterweight 11, turn the screw 14 to make the screw 14 rise along the axial direction of the limiting blind hole 13, and use the limiting plate 15 to push the support spring 16 upward, so that the friction block 17 at the upper end of the support spring 16 elastically frictionally contacts with the inner upper wall of the load-bearing body 1, thereby realizing the positioning of the counterweight 11.

[0023] like Figure 1 and Figure 2 As shown, in order to increase the placement stability of the pallets during static stacking, limiting grooves 18 are opened at the corners of the upper wall of the load-bearing body 1. The limiting grooves 18 are concave and match the shape of the support legs 2. They are used to limit the stacking of the load-bearing body 1. The bottom ends of the support legs 2 are inserted into the limiting grooves 18 to achieve stacking of the pallets. The bottom walls of the limiting plates 4 and the bottom walls of the support plates 5 are set at the same height. Between the stacked and limited pallets, the bottom walls of the support plates 5 and the limiting plates 4 are used to contact the upper wall of the lowered pallet to improve the stability of static placement.

[0024] When in use, in the storage state, the tray as a whole is inserted into the limiting groove 18 using the support legs 2, and the tray as a whole is stacked and placed;

[0025] When in use, the front shovel of a forklift can be inserted between the bottom wall of the load-bearing body 1 and the limiting plate 4 and into the cavity formed by the load-bearing plate 3 and the support plate 5 to limit the position of the front shovel of the forklift. The front shovel can also be limited by the opposite side walls of the support plate 5 and the support leg 2, thereby realizing the four-way fork transfer of the entire pallet.

[0026] After removing the pallet, place the goods on the load-bearing body 1. If the goods are unevenly placed or offset, the pallet can be counterweighted by adjusting the adjustable counterweight mechanism 6 inside the load-bearing body 1 to increase the transfer stability of the pallet. In the initial state, the counterweight rod 10 is in the center, and the counterweight blocks 11 at both ends are perpendicular to the load-bearing plate 3 and evenly distributed on both sides of the load-bearing plate 3.

[0027] After loading the goods and when counterweight is required, the counterweight rod 10 is slid and adjusted according to the gravity of the pallet so that the counterweight block 11 at one end of the counterweight rod 10 moves to the lighter side, and the position of the counterweight block 11 at one end is adjusted. The direction of the counterweight rod 10 can be rotated and adjusted using the connecting ring 1 7 and the connecting ring 2 8 to achieve counterweighting at different positions of the load-bearing body 1. After the position of the counterweight block 11 and the counterweight rod 10 is adjusted, the screw 14 is turned to rise axially along the limiting blind hole 13, and the limiting plate 15 is used to push the support spring 16 upward, so that the friction block 17 at the upper end of the support spring 16 is in elastic friction contact with the inner upper wall of the load-bearing body 1, thereby achieving the positioning of the counterweight block 11.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents. In short, if those skilled in the art are inspired by the present invention and, without departing from the purpose of the present invention, design structures and embodiments similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
