Further, the protrusion is a boss with edges.

Further, the number of the protrusions is 2 to 4.

Further, the horizontal angle formed by the reinforcing member and the upper edge is 50 degrees.

Further, the shape of the reinforcing piece is wedge-shaped.

Further, the body and the support body are hollow thin plate members formed by a vacuum forming machine.

Furthermore, the body and the support body are integrally formed or separately processed and fixedly formed.

Further, the support body is formed by a vacuum forming machine, and the body is made of polyethylene, polypropylene or polystyrene.

Compared with the prior art, the utility model realizes that the tray not only has the characteristics of high bearing capacity but also has good impact resistance, and at the same time, the tray also has the function of nested storage, which reduces the storage cost.

Detailed ways

The main idea of the utility model is to design a pallet with high bearing capacity and good impact resistance. Specific embodiments are described in detail below, but not as a limitation to the present utility model.

As shown in Figures 1-6, the utility model provides a pallet for carrying and stacking articles. The tray has a main body 1 of a tray forming part and a support body 2 arranged on the bottom surface of the main body. The structure and shape of the main body 1 are prior art, and its size, depth and shape can be made according to the requirements of the product to be contained; the support body The position, size, and height of 2 are also designed according to the requirements of the product to be loaded. The support body 2 is generally evenly arranged on the bottom surface of the body 1, such as the "Chuan" font distribution, and the front forks of the forklift are left between them. Free access to the space.

The present embodiment adopts 6 support bodies placed evenly as shown in Figure 1; A stepped support end 23 is provided at the connection, and a plurality of reinforcements 24 on the surface of the stepped support end 23 are provided on the outside between the bottom column 21 and the upper edge 22 . Wherein, the side wall of the bottom column 21 can also be provided with a plurality of reinforcing ribs to increase its overall load-bearing performance, and the upper edge 22 is connected with the bottom surface of the main body 1 . Certainly, in a tray molded with the same material, the upper edge 22 can also be integrated with the tray body 1 , that is, the upper edge 22 is a part of the bottom surface of the tray body 1 .

Wherein, as shown in Figures 4, 5, and 6, the stepped support end 23 is a stepped protrusion formed by extending the side wall of the bottom column 21 outward on different planes. The cross section of the protrusion is a 1/4 arc, and the circle The radius of the arc, that is, the radii of B-C and C-D in Figure 4, ranges from 5 mm to 20 mm. The number of protrusions is generally 2 to 4, and the number of protrusions can also be 1 or more. Here, the The utility model is not specifically limited. The reason why the protruding section of the utility model adopts a 1/4 arc is to absorb the impact through a large enough deformation space when the object falls and hits the tray, so as to produce good impact resistance; and the tray is subjected to still life Under heavy pressure, the support body 2 will not be deformed.

In a specific application embodiment, the shape of the cross-section of the protrusion can also be a 1/5, 1/6 arc, etc., and the radius of the above-mentioned arc ranges from 5 mm to 20 mm; or, the protrusion can also be The boss with edges, whether it is a 1/5 or 1/6 arc, or the inner space structure formed by the boss with edges is also used to absorb impact, and all have the characteristics of producing good impact resistance.

Wherein, as shown in Figures 2 and 6, a plurality of reinforcements 24 are uniformly arranged on the stepped support end 23, the reinforcements 24 are wedge-shaped, and cover the surface of the above-mentioned stepped support end 23 as a whole, and the two The ends are fixedly connected to the bottom column 21 and the upper edge 22 respectively. The wedge-shaped reinforcement 24 can prevent the stepped supporting end 23 from twisting too much when the tray is subjected to a dynamic impact such as falling objects or heavy pressure from a static object. As shown in Figure 5 again, since the utility model embodiment has adopted the protrusion of 2 1/4 circular arcs, when the angle α of the horizontal included angle α formed by the reinforcing member 24 and the upper edge 22 is 50 degrees, it can make The length from the F position to the O position is at least 1.5 times that from the D position to the O position, which better plays the role of preventing the stepped support end 23 from being too twisted as described above, and can also save the materials used for the reinforcement 24. .

In a specific application example, the angle of the horizontal angle α can also be any angle greater than or equal to 20 degrees and less than or equal to 80 degrees, and different angles of the horizontal angle α will cause the reinforcement 24 to produce a stepped shape. Support end 23 different support force.

In addition, the main body 1 of the tray molding described in the embodiment of the present invention and the support body 2 provided on the bottom surface of the main body can be integrally formed or fixed together after separate processing from different materials. Any of the existing technologies can be used, such as bonding, high-frequency welding, etc.; the body 1 and the support body 2 can also be hollow thin plate members formed by a vacuum forming machine.

Wherein, the above-mentioned tray body 1 may be made of polyethylene PE, polypropylene PP or polystyrene, and the support body 2 may be made of polyethylene PE material.

The utility model has been exemplarily described above by means of exemplary embodiments, but the utility model is not limited thereto. It should be understood that, without departing from the concept and working principle of the present utility model, the materials and shapes of the elements in the above embodiments can be replaced by other replacement or equivalent elements, materials, and applicable shapes known to those skilled in the art .
