Description

Technical Field

[0001] The present invention relates to a new type of tray. Background Art

[0002] A tray is a carrier for stacking goods and a tool for mechanized loading, unloading, and handling; the tray aggregates scattered small goods and containers in a certain quantity, and together with a forklift, forms a containerized unit transportation system in unit form. Therefore, the tray has become an indispensable and important appliance in the modern logistics system and is widely adopted by countries around the world; and for the tray, its own strength is the most important point.

[0003] In the current market, in order to facilitate the storage and transportation of trays, spaces corresponding to the feet of the tray are usually provided on the upper surface of the tray to facilitate the stacking of multiple trays; however, the setting of these spaces will greatly reduce the strength of the tray; and removing these spaces will prevent the trays from being stacked, increasing the occupied space for placement and making the storage and transportation processes of the trays more troublesome. Summary of the Invention

[0004] The present invention overcomes the deficiencies of the prior art and provides a new type of tray with a simple structure, reasonable design, higher strength, more stable load-bearing of goods, and convenient for storage and transportation.

[0005] To solve the above technical problems, the technical solution of the present invention is as follows:

[0006] A new type of tray includes a tray body, and an assembly groove and an assembly space are provided in the tray body; the assembly groove communicates with the assembly space, and the openings of both the assembly groove and the assembly space are provided on the upper surface of the tray body.

[0007] Furthermore, a support plate is provided at the opening of the assembly space; the support plates of each assembly space are at the same horizontal height; and the upper surface of each support plate is flush with the upper surface of the tray body.

[0008] Furthermore, the assembly space includes a support space and a fitting space; the inner diameter of the support space is larger than that of the fitting space; the support space is arranged above the fitting space and at one end close to the upper surface of the tray body; the support plate is arranged in the support space, and one side surface of the support plate contacts the bottom surface of the support space; both ends of the support plate contact the inner wall of the support space simultaneously or both sides of the support plate contact the inner wall of the support space simultaneously.

[0009] Furthermore, the tray body includes feet, and the feet are arranged on the lower surface of the tray body; each assembly space is respectively arranged in the corresponding foot.

[0010] Furthermore, the tray body is symmetrically arranged.

[0011] Furthermore, the supporting feet include a central supporting foot and peripheral supporting feet. The central supporting foot is arranged at the center of the tray body, and the peripheral supporting feet are arranged along the periphery of the tray body and surround the central supporting foot. The assembly grooves include an inner assembly groove and an outer assembly groove. The inner assembly groove enables the assembly spaces of the central supporting foot and the peripheral supporting feet to communicate with each other, and the outer assembly groove enables the assembly spaces of adjacent peripheral supporting feet to communicate with each other.

[0012] Furthermore, the outer assembly groove forms a large contact area surrounding on the upper surface of the tray body, and the inner assembly groove divides the large contact area into several small contact areas. The assembly groove further includes an auxiliary assembly groove, and the auxiliary assembly groove is arranged within the small contact areas.

[0013] Furthermore, reinforcing ribs are arranged on the lower surface of the tray body, and the reinforcing ribs are arranged corresponding to each of the auxiliary assembly grooves, inner assembly grooves, and outer assembly grooves.

[0014] Furthermore, the depths of the outer assembly groove and the inner assembly groove are greater than the length of the supporting space. The outer assembly groove and the inner assembly groove communicate with both the supporting space and the mating space at the same time.

[0015] Furthermore, limiting blocks are arranged on the outer surfaces of the central supporting foot and the peripheral supporting feet. The limiting blocks surround the central supporting foot and the peripheral supporting feet and are arranged in a stepped manner. The outer diameters of the limiting blocks at the ends of the central supporting foot and the peripheral supporting feet close to the lower surface of the tray body are the largest.

[0016] The beneficial effects of the present invention are as follows:

[0017] In the present invention, assembly grooves and assembly spaces are arranged within the tray body. The assembly grooves communicate with the assembly spaces, and the openings of the assembly grooves and the assembly spaces are both arranged on the upper surface of the tray body. When the trays need to be stored, the trays can be stacked through the assembly grooves and the assembly spaces. At the same time, when the trays are carrying goods, reinforcing materials can be placed in the assembly grooves and the assembly spaces to enhance the overall structural strength of the trays, avoiding damage to the tray body or the goods when various equipment transports goods through the trays. Also, a partial area of the goods can enter the assembly grooves and the assembly spaces, enabling an embedded fit between the tray body and the goods, making the fit between the goods and the trays more stable and tight.

[0018] In the present invention, through the arrangement of the support plates, a larger contact surface exists between the trays and the goods when the trays are carrying goods. At the same time, the support plates in each assembly space are at the same horizontal height, and the upper surfaces of the support plates are flush with the upper surface of the tray body, making the placement of the goods more stable.

[0019] In the present invention, one side surface of the support plate contacts the bottom surface of the support space; both ends of the support plate contact the inner wall of the support space at the same time, or both sides of the support plate contact the inner wall of the support space at the same time; this allows the support plate to fit more closely with the pallet body during assembly and provide sufficient supporting force for the support plate.

[0020] In the present invention, each assembly space is respectively arranged in a corresponding support foot; when the pallet needs to be stored, the support foot of the upper pallet can enter the assembly space of the lower pallet, so that the pallets can be stacked, which greatly reduces the space occupied by the pallets.

[0021] In the present invention, the tray body is symmetrically arranged, so that the overall supporting effect of the present invention is more stable.

[0022] In the present invention, the setting of the inner assembly groove and the outer assembly groove makes the assembly spaces of the corresponding support feet communicate with each other; when the method of inserting reinforcing materials is adopted to improve the overall structural strength of the pallet, an integrated reinforcing material can be placed in the communicating assembly grooves and assembly spaces, so that the strength of various parts of the pallet can be improved simultaneously; when the pallet body and the cargo are embedded in each other, the pallet body and the cargo can be more closely matched.

[0023] In the present invention, the provision of auxiliary assembly grooves allows more areas of the pallet body to be placed in reinforcing materials, further improving the strength of the pallet body; or allows more areas of the pallet body to be embedded with the cargo, allowing the pallet body and the cargo to fit more closely.

[0024] In the present invention, the provision of reinforcing ribs further improves the overall strength of the pallet.

[0025] In the present invention, the depth of the outer assembly groove and the inner assembly groove is greater than the length of the support space, so that when the present invention adopts the method of inserting reinforcement materials to improve the overall structural strength of the pallet, a support plate can still be set in the support space to avoid affecting the installation of the support plate.

[0026] In the present invention, the limit blocks arranged in a stepped shape can further limit the placement position of the present invention through the limit blocks of the support feet during the placement process, so that the present invention is more stable when carrying goods.

[0037] Embodiment:

[0038] Such as Figures 1-5As shown in the figure, a new type of tray includes a tray body 1, and an assembly groove 2 and an assembly space 3 are arranged in the tray body 1; the assembly groove 2 communicates with the assembly space 3, and the openings of the assembly groove 2 and the assembly space 3 are both arranged on the upper surface of the tray body 1; when the tray needs to be stored, the trays can be stacked through the assembly groove 2 and the assembly space 3; at the same time, when the tray is carrying goods, reinforcing materials can be placed in the assembly groove 2 and the assembly space 3 to improve the overall structural strength of the tray, so as to avoid damage to the tray body 1 or the goods when various equipment transports goods through the tray; or a part of the goods can enter the assembly groove 2 and the assembly space 3, so that the tray body 1 and the goods are in an embedded fit, making the fit between the goods and the tray more stable and tight.

[0039] In this embodiment, since the assembly groove 2 communicates with the assembly space 3, the reinforcing material placed can be an integral bracket, thereby greatly improving the strength of the tray.

[0040] In the present invention, a support plate 4 is further arranged at the opening of the assembly space 3. Through the arrangement of the support plate 4, a larger contact surface exists between the tray and the goods when the tray is carrying goods; the support plates 4 of each assembly space 3 are at the same horizontal height; and the upper surfaces of the support plates 4 are flush with the upper surface of the tray body 1, making the flatness of the tray higher and enabling the goods to be placed more stably when placed.

[0041] In this embodiment, the assembly space 3 includes a support space 31 and a fitting space 32; the inner diameter at the support space 31 is larger than the inner diameter at the fitting space 32; the support space 31 is arranged above the fitting space 32, at one end close to the upper surface of the tray body 1; the support plate 4 is arranged in the support space 31, one side surface of the support plate 4 contacts the bottom surface 34 of the support space, and both ends of the support plate 4 contact the inner wall of the support space 31 at the same time or both sides of the support plate 4 contact the inner wall of the support space 31 at the same time, so that when the support plate 4 is assembled, it fits more tightly with the tray body 1 and provides sufficient supporting force for the support plate 4; at the same time, since the assembly space 3 is arranged in the tray body 1, the structure at this place is relatively weak; and the support plate 4 itself has a certain strength. Through the close fit of the support plate 4 and the tray body 1, the problem that the structure at the assembly space 3 of the tray body 1 is relatively weak is made up, making the overall strength of the tray higher.

[0042] The tray body 1 includes feet 5, and the feet 5 are arranged on the lower surface of the tray body 1; each assembly space 3 is respectively arranged in the corresponding foot 5; when the tray needs to be stored, the feet 5 of the upper tray can enter the assembly space 3 of the lower tray, so that the trays can be stacked, greatly reducing the floor space occupied by the trays.

[0043] The tray body 1 is symmetrically arranged, making the overall support effect of the present invention more stable.

[0044] In this embodiment, the supporting feet 5 include a central supporting foot 51 and peripheral supporting feet 52. The central supporting foot 51 is arranged at the center of the tray body 1, and the peripheral supporting feet 52 are arranged along the periphery of the tray body 1 and surround the central supporting foot 51; the assembly grooves 2 include an inner assembly groove 21 and an outer assembly groove 22. The inner assembly groove 21 communicates the assembly space 3 of the central supporting foot 51 with the assembly space 3 of the peripheral supporting feet 52, and the outer assembly groove 22 communicates the assembly spaces 3 of adjacent peripheral supporting feet 52; the arrangement of the inner assembly groove 21 and the outer assembly groove 22 makes the assembly spaces 3 of the corresponding supporting feet 5 communicate; when using the method of putting in reinforcing materials to improve the overall structural strength of the tray, an integral reinforcing material can be placed in the communicating assembly grooves 2 and assembly spaces 3, so that the strength of each part of the tray is improved synchronously; when the tray body 1 is in an embedded fit with the goods, it can also make the tray body 1 and the goods fit more closely.

[0045] In this embodiment, the outer assembly groove 22 forms a large contact area on the upper surface of the tray body 1, and the inner assembly groove 21 divides the large contact area into several small contact areas; the assembly groove 2 further includes an auxiliary assembly groove 23, and the auxiliary assembly groove 23 is arranged in the small contact area; the arrangement of the auxiliary assembly groove 23 enables more areas of the tray body 1 to put in reinforcing materials, further improving the strength of the tray body 1; the arrangement of the auxiliary assembly groove 23 can also enable more areas of the tray body 1 to be in an embedded fit with the goods, making the tray body 1 and the goods fit more closely.

[0046] In this embodiment, there are nine supporting feet 5, and the distribution of the nine supporting feet 5 can meet the four-way insertion of the forklift; among them, the number of the central supporting feet 51 is one, and the number of the peripheral supporting feet 52 is eight. The eight peripheral supporting feet 52 surround a rectangular space, and the central supporting foot 51 is arranged at the center of this space; and because the eight peripheral supporting feet 52 surround a rectangular space, the large contact area is also rectangular, and the small contact areas are triangular; therefore, the auxiliary assembly grooves 23 in the small contact areas are arrow-shaped, and the bending parts of each auxiliary assembly groove 23 face the assembly space 3 of the central supporting foot 51; so that the tray body 1 and the inner assembly grooves 21, the outer assembly grooves 22, the auxiliary assembly grooves 23 and the assembly spaces 3 in the tray body 1 can be symmetrically arranged, making the overall support effect of the present invention more stable.

[0047] In some other ways, the auxiliary assembly groove 23 can also communicate with the assembly space 3 of the peripheral supporting feet 52, so that an integral reinforcing material can also be placed in the auxiliary assembly groove 23, further improving the strength of the tray.

[0048] In this embodiment, an auxiliary installation space 11 is further provided on the tray body 1, and the auxiliary installation space 11 communicates with the outer assembly groove 22. When the present invention uses the method of putting in reinforcing materials to improve the strength of the tray, the strength of the tray can be further improved by additionally putting in reinforcing materials through the auxiliary installation space 11. And because the auxiliary installation space 11 communicates with the outer assembly groove 22, the put-in reinforcing materials can adopt an integrated structure, further improving the strength of the present invention. When the tray body 1 and the goods are in an embedded fit, the auxiliary installation space 11 can also further increase the contact surface between the tray body 1 and the goods, making their fit closer. The bottom surface of the auxiliary installation space 11 is an inclined surface, which is not only convenient for the cooperation between the tray body 1 and the goods, but also convenient for the putting-in and taking-out of the reinforcing materials.

[0049] In this embodiment, reinforcing ribs 12 are provided on the lower surface of the tray body 1. The reinforcing ribs 12 are provided corresponding to each auxiliary assembly groove 23, inner assembly groove 21 and outer assembly groove 22. The setting of the reinforcing ribs 12 further improves the overall strength of the tray. At the same time, when the trays are stacked, the reinforcing ribs 12 can enter the corresponding auxiliary assembly groove 23, inner assembly groove 21 or outer assembly groove 22, making the trays more stable and safe when stacked.

[0050] In this embodiment, the depths of the outer assembly groove 22 and the inner assembly groove 21 are greater than the length of the support space 31. The outer assembly groove 22 and the inner assembly groove 21 communicate with the support space 31 and the mating space 32 at the same time. The depths of the outer assembly groove 22 and the inner assembly groove 21 being greater than the length of the support space 31 enables the present invention to still be able to set a support plate 4 in the support space 31 when using the method of putting in reinforcing materials to improve the overall structural strength of the tray, without affecting the installation of the support plate 4.

[0051] In this embodiment, limit blocks 53 are provided on the outer surfaces of the central support feet 51 and the peripheral support feet 52. The limit blocks 53 surround the central support feet 51 and the peripheral support feet 52 and are arranged in a stepped manner. The outer diameter of the limit blocks 53 at one end of the central support feet 51 and the peripheral support feet 52 close to the lower surface of the tray body 1 is the largest. The stepped limit blocks 53 enable the present invention to further limit the placement position of the present invention through the limit blocks 53 of the support feet 5 during the placement process, making the present invention more stable when carrying goods. It should be noted that the limit blocks 53 of the central support feet 51 and each peripheral support feet 52 are correspondingly arranged.

[0052] In this embodiment, a disassembly groove 33 is further provided at the opening of the assembly space 3 of the peripheral support feet 52, which is convenient for separating the stacked trays.

[0053] In some preferred embodiments, the lengths of the supporting feet 5 are the same; and a connecting rod 6 is further provided to connect the bottoms of the supporting feet 5 in the same row or the same column, making the placement of the present invention more stable and preventing the supporting feet 5 from deforming.

[0054] The following compares some technical parameters of the tray of the present invention with those of the trays in the prior art to further illustrate the performance of the tray in the present invention.

[0055] The trays participating in the comparison are the tray of the present invention (hereinafter referred to as "this tray"), the tray disclosed in Chinese Patent CN206172060U (hereinafter referred to as "comparative tray 1"), and the tray disclosed in Chinese Patent CN212290843U (hereinafter referred to as "comparative tray 2").

[0056] This comparison is carried out from three aspects: the compressive performance a of the support legs, the bending performance b of the reinforcing ribs, and the anti-fracture performance c of the support legs.

[0057] The sizes of comparative tray 1 and comparative tray 2 are both less than 1100×1100 mm, and the thickness is about 1.05 - 1.15 times that of this tray. The results are as follows:

[0058] (1) Overall load-bearing: When the size of this tray is 15 - 20% larger than that of comparative tray 1 and comparative tray 2, it still has a load-bearing capacity similar to that of comparative tray 1 and comparative tray 2 (usually, a larger-sized tray has a poorer load-bearing capacity due to its thinner thickness and worse edge stress, compared with a smaller tray with a higher density and thickness).

[0059] (2) Compressive performance of the support legs: The average measured value of the strength that the support legs of comparative tray 1 can withstand is 2529 KG; the average measured value of the strength that the support legs of comparative tray 2 can withstand is 2486 KG; the average measured value of the strength that the support legs of this tray can withstand is 3782 KG; therefore, the load-bearing capacity of this tray is better than that of comparative tray 1 and comparative tray 2.

[0060] (3) Bending performance of the reinforcing ribs: The average measured value of the strength that the reinforcing ribs of comparative tray 1 can withstand is 368 KG; the average measured value of the strength that the reinforcing ribs of comparative tray 2 can withstand is 376 KG; while the average measured value of the strength that the reinforcing ribs of this tray can withstand is 483 kg; therefore, the overall strength of this tray is higher than that of comparative tray 1 and comparative tray 2.

[0061] (4) Support leg anti-breakage performance: When the support legs are subjected to shaking, swaying, bumping, twisting and other vibrations, the support legs of comparison pallet 1 were damaged after an average of 8546 times of bearing the load; the support legs of comparison pallet 2 were damaged after an average of 9125 times of bearing the load; the support legs of this pallet were damaged after an average of 12376 times of bearing the load; therefore, this pallet has higher durability.

[0062] In summary, the performance of this pallet is better than that of comparison pallet 1 and comparison pallet 2.

[0063] It is worth noting that other technical solutions of the present invention belong to the prior art and will not be described in detail.

[0064] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
