It should be understood that the present invention can have various variations in different embodiments, all of which do not depart from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes and not intended to limit the present invention.

[0021] To further illustrate the principle and structure of the present invention, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Referring to Figure 1 , an embodiment of the present application provides a tray 100 for cooperating with the packaging of goods during goods transportation to achieve efficient transportation of goods. Compared with existing trays of the same size, under the same load capacity specifications, the tray 100 of the present application can reduce weight by 30% - 40%. The tray 100 includes a main beam 10 and a slat 20.

[0023] Among them, there are multiple main beams 10, and the multiple main beams 10 are parallel and spaced apart. The extending direction of the main beam 10 is the same as the width direction of the tray 100, and a plurality of accommodation grooves are provided at intervals along the extending direction of the bottom of the main beam 10. In the length direction of the tray 100, the positions of the accommodation grooves of the multiple main beams 10 correspond to each other.

[0024] There are multiple slats 20, which are respectively arranged on the upper surface and the lower surface of the main beam 10. The slats are cross-connected with the main beam 10, and both ends of the slat 20 are respectively fixed on the main beam 10 at both ends of the tray 100. The slat 20 has a U-shaped structure with an opening. The slat 20 includes a fixed arm 201 and connecting arms 202 bent and connected to both ends of the fixed arm 201. The connecting arms 202 are L-shaped. The bottom of the connecting arm 202 of the slat 20 arranged on the upper surface of the main beam 10 is fixed to the upper surface of the main beam 10. The slat 20 arranged on the lower surface of the main beam 10 is located in the accommodation groove, and the bottom surface of the slat 20 arranged on the lower surface of the main beam 10 is flush with the lower surface of the main beam 10.

[0025] Furthermore, the main beam 10 of this embodiment is a sheet metal stamping structural part. By using high-strength steel to stamp the main beam 10, the overall structural strength of the tray 100 can be guaranteed.

[0026] In this embodiment, there are three main beams 10, and the three main beams 10 are arranged in parallel and at intervals. It can be understood that the number of main beams 10 is not limited to three. It can be set to four, five, seven, etc. according to the design requirements of the size of the tray 100. Here, the number of main beams 10 is not overly limited.

[0027] The main beam 10 is integrally trapezoidal in an inverted shape, with an opening at the beginning and hollow inside. This setting can achieve weight reduction of the main beam 10 and further realize the lightweight design of the tray 100. A plurality of fork holes 11 are opened on the main beam 10. The fork holes 11 are oval-shaped, and the fork holes 11 are used to cooperate with a forklift to realize the transfer of the tray 100 together with the goods on the tray 100.

[0028] A plurality of fork holes 11 are arranged at intervals on the side surface of the main beam 10 along the extending direction of the main beam 10. The fork holes 11 penetrate the main beam 10 along the length direction of the tray 100. In the length direction of the tray 100, the positions of the fork holes 11 on the plurality of main beams 10 correspond. Through the fork holes 11, the forklift can cooperate with the tray 100 to realize the transfer of goods. At the same time, in the width direction of the tray 100, the interval between two adjacent main beams 10 is also available for the forklift to insert the fork, so that the forklift can insert the fork on all four circumferential sides of the tray 100, making the forklift transfer operation more convenient and flexible.

[0029] The tray 100 of this embodiment further includes a reinforcing plate 50, and the reinforcing plate 50 is an arc-shaped plate. The reinforcing plate 50 is arranged on the inner wall of the fork hole 11 and is arranged close to the upper surface of the main beam 10.

[0030] By arranging the reinforcing plate 50, the structure of the inner wall of the fork hole 11 can be strengthened, the structural strength of the main beam 10 at the fork hole 11 can be guaranteed, and the overall structure of the tray 100 can be made more stable.

[0031] It can be understood that, in addition to the arc shape shown in this embodiment, the reinforcing plate 50 can also be a flat plate, an arc plate or an oval plate, as long as the reinforcing plate 50 adapts to the inner wall shape of the fork hole 11. At the same time, in addition to being arranged at the top of the fork hole 11, the reinforcing plate 50 can also be arranged at the bottom of the fork hole 11, the side wall of the fork hole 11 or the inner wall of the fork hole 11, as long as it can strengthen the structural strength at the fork hole 11.

[0032] In this embodiment, a plurality of receiving grooves are provided on the lower surface of the main beam 10, and the plurality of receiving grooves are arranged at intervals along the extending direction of the main beam 10. In the length direction of the tray 100, the positions of the receiving grooves on the plurality of main beams 10 correspond to each other.

[0033] Among them, the receiving grooves at both ends of the main beam 10 are the first receiving grooves 12, and the first receiving grooves 12 are of a stepped structure. The receiving grooves between the two first receiving grooves 12 are the second receiving grooves 13, and the second receiving grooves 13 are of a trapezoidal structure. The second receiving groove 13 forms a notch on the outer surface of the main beam 10 for the passing of the packing belt.

[0034] Furthermore, the slats 20 provided on the upper surface of the main beam 10 are upper slats, and there are a plurality of upper slats. The upper slats are sheet metal stamping structural parts. By using high-strength steel to stamp the upper slats, the overall structural strength of the tray 100 can be guaranteed. In this embodiment, the number of the upper slats is ten. It can be understood that the number of the upper slats can be changed accordingly according to the design size of the tray 100, and is not limited to ten.

[0035] The plurality of upper slats include first upper slats 21 provided at both ends of the main beam 10 and a plurality of second upper slats 22 between the first upper slats 21 provided at both ends of the main beam 10.

The openings of the first upper slat 21 and the second upper slat 22 both face the upper surface of the main beam 10, and both are fixed to the main beam 10 through the bottom of the connecting arm 202.

[0037] The setting of the upper slats in a C-shaped structure can form a stable connection on the surface of the main beam 10 and ensure the supporting strength for the goods. At the same time, the C-shaped upper slats can reduce the self-weight while ensuring the structural strength, realize the lightweight design of the tray 100, reduce the occupation of the cargo carrying capacity, and improve the transportation efficiency of the goods.

[0038] In this embodiment, the bottoms of the connecting arms 202 of the first upper slat 21 and the bottoms of the connecting arms 202 of the second upper slat 22 are both fixed to the upper surface of the main beam 10 to form a stable connection. The bottom end of the connecting arm 202 of the first upper slat 21 is bent upward to form an arc chamfer 211. The arc chamfer 211 forms a smooth flanging on the outer side of the first upper slat 21 to prevent the edge of the first upper slat 21 from cutting the packing belt, enabling the packing belt to be stably wound around the pallet 100 and realizing effective packing and loading of goods.

[0039] Both the first upper slat 21 and the second upper slat 22 are provided with a plurality of weight-reducing holes 203 to further realize the lightweight of the pallet 100. The weight-reducing holes 203 are arranged on the fixed arms 201 of the upper slats, and the plurality of weight-reducing holes 203 are arranged at intervals along the extending direction of the upper slats.

[0040] In addition, the pallet 100 of this embodiment further includes a protective strip 30. The protective strip 30 is arranged on some of the first upper slats 21 and some of the second upper slats 22, and the protective strip 30 covers the surface of the fixed arm 201 of the upper slat. The protective strip 30 is made of a composite material and is bonded to the upper slat with glue, which is used to protect the upper slat, prevent the goods from wearing the upper slat, and extend the service life of the pallet 100.

[0041] Further, the slats 20 arranged on the lower surface of the main beam 10 are lower slats. There are a plurality of lower slats, and the plurality of lower slats are arranged in one-to-one correspondence with a plurality of receiving grooves on the lower surface of the main beam 10. The lower slats are sheet metal stamping structural parts. By using high-strength steel to manufacture the lower slats, the overall structural strength of the pallet 100 can be ensured. In this embodiment, the number of lower slats is four. It can be understood that the number of lower slats can be changed accordingly according to the design size of the pallet 100, and is not limited to four.

[0042] The plurality of lower slats include first lower slats 23 arranged at both ends of the main beam 10 and a plurality of second lower slats 24 arranged between the first lower slats 23 at both ends of the main beam 10. In this embodiment, one first lower slat 23 is arranged at both ends of the main beam 10, and the number of second lower slats 24 is two.

[0043] In this embodiment, both the first lower slat 23 and the second lower slat 24 are in a C-shaped structure with an opening, and both the first lower slat 23 and the second lower slat 24 include a fixed arm 201 and connecting arms 202 bent and connected to both ends of the fixed arm 201. The connecting arm 202 is L-shaped.

[0044] Among them, the first lower slat 23 is disposed in the first receiving groove 12. The opening of the first lower slat 23 faces the lower surface of the main beam 10, and the bottom surface of the fixing arm 201 of the first lower slat 23 is flush with the lower surface of the main beam 10. In this embodiment, the portion of the connecting arm 202 of the first lower slat 23 located between adjacent ones is bent downward to form a bent edge 231, and the bent edge 231 is an arc-shaped edge.

[0045] In this embodiment, an arc-shaped bent edge 231 is provided on the outer side of the first lower slat 23, which can form a smooth transition between the first lower slat 23 and the packing belt, avoid the edge of the first lower slat 23 from cutting the packing belt, and ensure that the packing belt firmly binds and fixes the goods on the pallet 100.

[0046] The second lower slat 24 is disposed in the second receiving groove 13, and the second receiving groove 13 is adapted to the outer contour of the second lower slat 24.

[0047] By disposing the lower slat in the receiving groove and making the bottom surface of the lower slat flush with the lower surface of the main beam 10, the pallet 100 can be stably located on the ground or the carrying device, and the pressure borne by the lower slat can be effectively transmitted to the main beam 10, ensuring that the pallet 100 stably bears the goods and improving the load capacity of the pallet 100 for the goods.

[0048] At the same time, setting the second lower slat 24 with an opening facing downward is for passing the packing belt, that is, the packing belt tied perpendicular to the main beam 10 is fixed through the downward opening of the second lower slat 24. The packing belt passes through the opening of the second lower slat 24 instead of passing through the fork holes 11 on the main beam 10 to ensure that the packing belt can stably bind the goods and avoid the fork of the forklift from cutting the packing belt when passing through the fork holes 11, ensuring the integrity of the packing belt.

[0049] In this embodiment, a plurality of weight-reducing holes 203 are provided on both the first lower slat 23 and the second lower slat 24 to further realize the light weight of the pallet 100.
