DETAILED DESCRIPTION

[0017] Example one

[0018] As Figures 1 to 3As shown, a tray convenient for stacking placement includes a tray top plate 1 and a tray bottom plate 2, the tray top plate 1 and the tray bottom plate 2 are connected through a plurality of support columns 3, a forking space is formed between adjacent two support columns 3, the top surface of the tray top plate 1 is provided with a tapered limiting column 4, the diameter of the tapered limiting column 4 gradually decreases away from the tray bottom plate 2, the tray bottom plate 2 is provided with a limiting circular hole 5, the limiting circular hole 5 communicates with the forking space, the tapered limiting column 4 of one tray is fitted in the limiting circular hole 5 of the adjacent tray, the stacking position of the tray is provided with a base plate, the base plate is fixedly installed, the top of the base plate is fixedly provided with a plug-in column, the plug-in column is fitted in the limiting circular hole 5 of the lowermost tray, when the tray is stacked upwards, the tapered limiting column 4 of the lower layer tray will be inserted into the limiting circular hole 5 of the upper layer tray, thereby limiting the movement freedom degree in the horizontal direction of the tray, and further improving the stability of the tray stacking, since the tray group stacked together is also limitedly arranged on the base plate, the tray as a whole also has high stability, and is not easy to collide and fall, thereby improving the safety; the minimum diameter of the tapered limiting column 4 is smaller than the diameter of the limiting circular hole 5, so that the tapered limiting column 4 can be inserted into the limiting circular hole 5 within a certain range, facilitating the tray limiting stacking; since the freedom degree in the vertical direction of the tray is not limited, the forklift can directly fork the tray to move upwards, so that the upper tray can be taken out and put into use, which has high stability and does not affect the normal forking operation of the tray.

[0019] Example two

[0020] On the basis of example one, as shown in Figure 1 and Figure 3 the bottom surface of the tray top plate 1 is provided with a plurality of forking limiting grooves 15, the two side walls of the forking limiting groove 15 are fixedly provided with rubber pads 16, the thickness of the rubber pad 16 gradually increases from bottom to top, the tines of the forklift are inserted from the forking space, and then the tines move upwards into the forking limiting groove 15, after the tines lift the tray, the tines are pressed against the rubber pad 16 to fit in the forking limiting groove 15 under the action of the tray and the goods on the tray, realizing the forking limiting of the tray, and avoiding the tray from falling off the tines.

[0021] Example three

[0022] On the basis of example two, as shown in Figure 1 and Figure 2As shown, mounting holes 6 are arranged at the four corners of the top surface of the tray top plate 1, and the tapered limiting columns 4 are slidably fitted in the mounting holes 6. The tapered limiting columns 4 have the freedom of moving along the axial direction of the mounting holes 6. The bottom of each tapered limiting column 4 is connected with a telescopic assembly. The telescopic assembly is connected to the support column 3 at the end away from the tapered limiting column 4. When an article is placed on the tray, the article presses the tapered limiting column 4 downward to make the telescopic assembly retract, so that the tapered limiting column 4 moves into the mounting hole 6. Thus, the article is directly supported by the tray top plate 1, which has a large contact area and does not affect the stability of the article placement. Since the thickness of the tray top plate 1 is relatively small, the tapered limiting column 4 cannot be installed with the freedom of moving. Therefore, the tapered limiting column 4 is slidably installed in the forking space, so that the tapered limiting column 4 can be smoothly installed.

[0023] Example Four

[0024] On the basis of Example Three, as shown in Figure 1 and Figure 3 The telescopic assembly comprises a fixed column 7 and a moving column 8. One end of the fixed column 7 is connected to the support column 3, and the other end is slidably connected with the moving column 8. The end of the moving column 8 away from the fixed column 7 is connected with the tapered limiting column 4. A spring 9 is arranged in the fixed column 7. A small-diameter groove 10 and a large-diameter groove 11 are sequentially arranged in the top of the fixed column 7 along the axial direction of the fixed column 7. The moving column 8 is slidably fitted in the small-diameter groove 10. A limiting plate 12 is slidably arranged in the large-diameter groove 11. The diameter of the limiting plate 12 is larger than that of the small-diameter groove 10. The moving column 8 is connected with the limiting plate 12. The spring 9 is arranged in the large-diameter groove 11. The two ends of the spring 9 are respectively connected with the fixed column 7 and the limiting plate 12. When an article is placed on the tray, the article will press the tapered limiting column 4 downward. The tapered limiting column 4 will press the spring 9 downward through the moving column 8, so that the moving column 8 moves downward, and the tapered limiting column 4 moves into the mounting hole 6. Thus, the article and the tray have a large contact area, and the stability of the article placement is not affected. It is worth noting that the spring 9 is arranged in the fixed column 7, so that the use of the spring 9 is not affected, the spring 9 is protected, and the service life is prolonged.
