[0036] The tray 1 made of high-strength steel not only has a high load capacity but also a light self-weight.

[0037] The tray 1 with a high load capacity, a light self-weight and the ability to nest meets the high requirements of the market for trays very well and fills the market gap.

[0038] The following specifically introduces the structure of the tray 1.

[0039] Figure 4 The schematic structural diagram of an embodiment of the tray body 11 is shown. Referring to Figure 4 , the tray body 11 includes at least openings 115 arranged at both ends in the first direction. The openings 115 extend in the second direction. The first direction and the second direction are in the same plane and perpendicular to each other. Among them, in this embodiment, the first direction refers to the length direction of the tray body 11, and the second direction refers to the width direction of the tray body 11.

[0040] In this embodiment, the tray body 11 includes two openings 115, and the two openings 115 are arranged at both ends of the tray body 11 in the first direction. In other embodiments, the tray body 11 may further include three openings 115, and the tray body 11 may also include four openings 115 or other numbers of openings 115. The multiple openings 115 are arranged at intervals along the first direction of the tray body 11.

[0041] The tray body 11 is square, and specifically includes two parallel and spaced longitudinal beams 111, a plurality of cross beams 112 arranged between the two longitudinal beams 111, and connection frames 113 arranged between adjacent two openings 115.

[0042] The longitudinal beam 111 extends along the first direction, and the cross beam 112 extends along the second direction.

[0043] Wherein, when the number of the openings 115 is three, four or more, the number of the connecting frames 113 is two, three or more. That is, a connecting frame 113 is provided between any two adjacent openings 115.

[0044] In this embodiment, the number of the cross beams 112 is four, which are respectively the end cross beams 112, the first intermediate cross beam 112 and the second intermediate cross beam 112. An opening 115 is formed by enclosing one end cross beam 112, the first intermediate cross beam 112 and the two longitudinal beams 111. Another opening 115 is formed by enclosing the other end cross beam 112, the second intermediate cross beam 112 and the two longitudinal beams 111.

[0045] The connecting frame 113 is located between the two openings 115. Specifically, the connecting frame 113 includes a plurality of side beams 1131 arranged in parallel at intervals and a connecting beam 1132 connected between the plurality of side beams 1131. Wherein, the side beams 1131 extend along the first direction, and the connecting beam 1132 extends along the second direction.

[0046] Both ends of the connecting beam 1132 protrude out of the side beams 1131 and are connected to the longitudinal beam 111.

[0047] The connecting frame 113 is also fixedly connected to the adjacent cross beam 112. Specifically, the connecting frame 113 is fixedly connected to the first intermediate cross beam 112 and the second intermediate cross beam 112 to enhance the strength of the tray body 11.

[0048] The longitudinal beam 111, the cross beam 112, the connecting beam 1132 and the side beam 1131 in this embodiment are all square tubular.

[0049] The shovel feet 12 are arranged corresponding to the openings 115 and are located at the bottom of the tray body 11. In this embodiment, the number of the openings 115 is two, that is, the number of the shovel feet 12 is also two. In other embodiments, when the number of the openings 115 is three, the number of the shovel feet 12 is also three. The shovel feet 12 are arranged in one-to-one correspondence with the openings 115.

[0050] The shovel feet 12 are connected to the tray body 11 and protrude downward from the tray body 11. Therefore, when two trays 1 are nested, the shovel feet 12 of one tray 1 can be stacked on the shovel feet 12 of the other tray 1 through the openings 115 of the other tray 1, that is, the shovel feet 12 of the tray 1 located above are stacked on the shovel feet 12 of the tray 1 located below through the openings 115 of the tray 1 located below, realizing the nesting of the two trays 1.

[0051] Figure 5 The structural schematic diagram of the shovel feet 12 is shown. Refer to Figure 5, the spade foot 12 includes a spade foot main body 121 and a reinforcing member 122.

[0052] Along the second direction, the spade foot 12 includes a main body portion 1211 and inclined portions 1212 provided at both ends of the main body portion 1211. The two inclined portions 1212 and the main body portion 1211 constitute the spade foot main body 121.

[0053] The main body portion 1211 extends along the second direction and is located below the tray main body 11, and there is a height difference between the main body portion 1211 and the tray main body 11.

[0054] The inclined portions 1212 are located at the ends of the main body portion 1211 along the second direction and are inclined. Specifically, the inclined direction of the inclined portions 1212 is inclined downward from the outside to the inside. Among them, with the use state of the tray main body 11 as a reference, the direction towards the inside of the tray main body 11 is the inside, and the opposite is the outside.

[0055] The inclined portions 1212 are arc-shaped, with their convex surfaces facing downward, that is, the inclined portions 1212 have a smooth transition.

[0056] There is a smooth transition between the inclined portions 1212 and the main body portion 1211.

[0057] With the above structure, the two inclined portions 1212 and the main body portion 1211 can be integrally formed, making the manufacturing simple. The two inclined portions 1212 and the main body portion 1211 can also be spliced by welding. And because the inclined portions 1212 are arc-shaped and there is a smooth transition between the inclined portions 1212 and the main body portion 1211, only butt welding of the inclined portions 1212 and the main body portion 1211 is required, reducing the welding workload.

[0058] In addition, the inclined portions 1212 are arc-shaped and the smooth transition between the inclined portions 1212 and the main body portion 1211 can avoid damage to the ground, that is, it is friendly to the ground.

[0059] Along the first direction, the spade foot main body 121 includes a convex protrusion 1213. The protrusion 1213 extends along the first direction, that is, along the direction of the spade foot main body 121. And the protrusion 1213 is located in the middle of the spade foot main body 121 along the second direction, and the protrusion 1213 is arc-shaped. This structure of the spade foot main body 121 further avoids stress concentration when the spade foot 12 bears weight and ensures strength.

[0060] The reinforcing member 122 is used to connect the spade foot main body 121 and the tray main body 11 to increase the connection strength. Specifically, reinforcing members 122 are provided on both sides of each spade foot main body 121 along the second direction.

[0061] Each reinforcing member 122 includes two diagonal braces 1221. There is a gap between the tops of the two diagonal braces 1221, and both are connected to the tray body 11. The bottoms of the two diagonal braces 1221 are connected to each other and both are connected to the main body portion 1211. That is, the reinforcing member 122 is V-shaped.

[0062] In this embodiment, the diagonal brace 1221 is in the shape of a square tube.

[0063] Furthermore, each top of the diagonal brace 1221 has an inclined surface that slopes downward toward the main body portion 1211. When the trays 1 are stacked, the shovel feet 12 located above move downward along the inclined surface of the shovel feet 12 located below until they are stacked on another shovel foot 12, thereby realizing the nesting of the two trays 1.

[0064] The bottom of each reinforcing member 122 and the main body portion 1211 are connected through a bottom transition plate 123. Specifically, the bottom transition plate 123 is fixed to the side surface of the main body portion 1211, and the bottoms of the two diagonal braces 1221 are both connected to the bottom transition plate.

[0065] The top of each reinforcing member 122 and the tray body 11 are connected through a top transition plate 124. Specifically, the top transition plates 124 correspond to the diagonal braces 1221 one by one. That is, the number of top transition plates 124 is two, and the tops of the two diagonal braces 1221 are respectively connected to the tray body 11 through a top transition plate 124.

[0066] In this embodiment, the top transition plate 124 wraps the top of the diagonal brace 1221, thereby increasing the connection strength between the diagonal brace 1221 and the tray body 11. Specifically, the top transition plate 124 includes a connecting portion, a top wrapping portion, and a side wrapping portion. The connecting portion is arranged on the side surface of the diagonal brace 1221 facing the adjacent cross beam 112, the top wrapping portion is fixed to the top of the diagonal brace 1221, and the side wrapping portion is fixed to the side surface of the diagonal brace 1221 away from the adjacent cross beam 112.

[0067] In other embodiments, the top transition plate 124 can also be in the shape of a flat plate. It is fixed to the side surface of the cross beam 112 facing the main body portion 1211 and is fixedly connected to the diagonal brace 1221, thereby realizing the connection between the reinforcing member 122 and the tray body 11 and the shovel foot main body 121. The two top transition plates 124 of each reinforcing member 122 can also be connected to form an integral transition plate.

[0068] In this embodiment, the reinforcing member 122 is connected to the middle of the shovel foot main body 121 along the second direction.

[0069] According to the above description, in this embodiment, the pallet 1 includes a pallet body 11 and spade feet 12 provided corresponding to the opening 115 of the pallet body 11, and the spade feet 12 protrude downward from the pallet body 11, so that the spade feet 12 of one pallet 1 can pass through the opening 115 of another pallet 1 and stack on the spade feet 12 of another pallet 1, enabling the pallets 1 to be nested with each other.

[0070] Figure 6 Fig. 4 shows a schematic structural diagram of two nested pallets 1. Figure 7 Fig. 5 shows a view in one direction of the nesting of two pallets 1. Combining Figure 6 and Figure 7 , place one pallet 1 on the support surface, then align the spade feet 12 of another pallet 1 with the opening 115 of the pallet 1 on the support surface, and then place the other pallet 1 downward so that the spade feet 12 stack on the spade feet 12 to achieve the nesting of the two pallets 1.

[0071] Exemplarily, the nesting recovery ratio that the pallet 1 in this embodiment can achieve is 1:3.

[0072] In addition, in this embodiment, since the spade feet 12 of the pallet 1 are arranged at intervals in the first direction and there is a height difference between the main body portion 1211 of the spade feet 12 and the pallet body 11, the pallet 1 can be four-way fork-lifted, which is convenient for forklift operation. The pallet 1 can also be transported by a pallet jack.

[0073] The pallet 1 in this embodiment has at least two spade feet 12 arranged at intervals, and the spade feet 12 can be placed on two cross beams 112 arranged at intervals on the shelf, so that the pallet 1 can be placed on a three-dimensional shelf and applied to a production line. From the above technical solutions, the advantages and positive effects of the present invention are as follows:

[0074] The material of the pallet in the present invention is metal, so that the load capacity of the pallet is relatively large, which can meet the increasing load requirements. And the pallet includes a pallet body and spade feet provided corresponding to the opening of the pallet body, and the spade feet protrude downward from the pallet body, so that the spade feet of one pallet can pass through the opening of another pallet and stack on the spade feet of another pallet, enabling the pallets to be nested with each other, reducing the space requirement for empty pallets, increasing the loading rate of a single trip when transporting pallets, thereby improving the transportation efficiency and reducing the operating cost of the enterprise.
