Technical Field
[0001] The utility model relates to the technical field of trays, in particular to a tray which is easy to stack. Background Art
[0002] A pallet is a medium that turns static goods into dynamic goods, a cargo platform, and an active platform, or a movable ground. Even goods that lose their flexibility when placed on the ground will immediately become active and become flexible mobile goods once they are loaded on the pallet, because the goods loaded on the pallet are always ready to move. For example, a patent document with announcement number CN219030122U discloses an easily stackable plastic pallet, including a pallet, a positioning groove, a support column, a support tube, an anti-slip strip, and a side connection mechanism. The pallet is provided with a positioning groove, four evenly distributed support columns are fixedly connected to the inside of the pallet, a support tube is fixedly connected to the inside of the pallet, an anti-slip strip is bonded to the inside of the support tube, and a side connection mechanism is provided on the pallet. The utility model adds connecting plates, fixing strips, round-headed columns and other structures on the pallets. During the process of stacking the pallets, two adjacent pallets can be connected through the sliding connection between the round-headed columns and the connecting plates, thereby increasing the pulling force between the multiple pallets, avoiding the problem of unstable placement of pallets after being stacked too high, and making the pallets easier to stack. However, if the pallets are directly stacked in an empty state, they will be unstable and prone to collapse when transporting the empty pallets as the height increases. Currently, the surfaces of the pallets are basically provided with stripes that increase friction, which can greatly maintain the stability of pallet stacking, but are difficult to pull out and use when needed. Multiple people are required to lift them up, which greatly affects the use efficiency. Therefore, it is urgent to design a pallet that is easy to stack to solve the above problems.

[0023] Furthermore, inner grooves 102 are provided at the centers of both ends of the pallet 1, and outer arc surfaces 101 are provided on the four sides of the pallet 1, so as to facilitate stacking with other pallets to save space.
[0024] Furthermore, a protruding block 201 is fixedly provided at the bottom end of the connection port 2, and inner arc surfaces 202 are provided on four inner sides of the protruding block 201. This design allows the two sets of trays to be separated for easy use.
[0025] As a further feature of the present invention, both ends of the main rotating rod 4011 in the transmission assembly 401 respectively penetrate the center of the fixed bearing 4012 fixed at the front and rear ends of the center of the support plate 1, and the front and rear ends of the main rotating rod 4011 are fixed with rotating disks 4013 to facilitate operation and improve use effect.
[0026] Furthermore, both ends of the auxiliary shaft 4041 in the rotating component 404 are connected to the internal center of the limit bearing 4042, and gears 4043 are fixed on both sides of the auxiliary shaft 4041. The inner side of the gear 4043 engages with the front end of the telescopic clamp 405. The slide rail 4051 in the telescopic clamp 405 is fixed to the inner wall of the bottom groove 103, and the front end of the slide rail 4051 is sleeved with a T-shaped slider 4052. The front end of the T-shaped slider 4052 is fixedly connected to the rear wall of the rack plate 4053, and the front end of the rack plate 4053 engages with the gear 4043, thereby improving efficiency and reducing labor burden.

[0028] Working principle: when the tray is not needed, the bottom end of the connecting port 201 in a group of pallets 1 can be aligned with the top of the lower group of connecting ports 2 to place the pallet. The stability can be improved by a small amount of friction strips 3 provided on the top of the pallet 1. When the pallet 1 needs to be taken out, it is only necessary to rotate the rotating disk 4013 at both ends of the pallet 1. The rotation of the rotating disk 4013 drives the main rotating rod 4011 to rotate. The rotation of the main rotating rod 4011 drives the connected main rotating belt 402 and the auxiliary rotating belt 403 to rotate respectively. The main rotating belt 402 and the auxiliary rotating belt 403, at both ends, respectively drive the auxiliary rotating shaft 4041 in the rotating assembly 404 to rotate. The rotation of the auxiliary rotating shaft 4041 synchronously drives the gears 4043 on both sides to rotate. When the gear 4043 rotates, it can engage the rear rack plate 4053 to move downward. Under the action of the rear T-shaped slider 4052, the rack plate 4053 pushes the lower group of pallets 1 to separate this pallet 1 from the lower side pallet 1 for easy removal. The above is the entire working principle of the utility model.
