Description

Technical Field

[0001] The present utility model relates to the technical field of tray production, and relates to a new type of tray. Background Art

[0002] As an important tool widely used in industries such as logistics and warehousing, the bottom structure of the tray has various designs, such as the "day" shape and the more complex "field" shape, etc. The injection mold design of the injection molding machine plays a core role in the tray production process and is a key factor determining whether the bottom structure of the tray can be accurately formed.

[0003] In actual production, the mold design of the injection molding machine directly determines the bottom structure of the tray. For production enterprises that already have a tray mold with a "day" - shaped bottom structure, if they hope to produce a tray with a "field" - shaped bottom structure, they usually need to re - design and open a new mold. However, the re - opening of the mold not only involves high costs but also requires equipment adjustment and other issues. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a new type of tray.

[0005] A new type of tray provided by the present application adopts the following technical scheme:

[0006] A new type of tray includes a tray and a reinforcing plate; the tray includes a tray surface and support feet, there are multiple support feet, the support feet are evenly arranged on the bottom wall of the tray surface, and the tray surface and the support feet are integrally formed; a lower rib plate is fixedly arranged between adjacent support feet, the lower rib plate is arranged horizontally or vertically between the support feet and forms a "day" - shaped structure; there are two reinforcing plates, and the reinforcing plates are detachably installed horizontally or vertically between the support feet and jointly form a "field" - shaped structure with the lower rib plate.

[0007] By adopting the above - mentioned technical scheme, the bottom of the tray is designed as a "day" - shaped structure and combined with a detachable reinforcing plate to form a "field" - shaped structure; when high - strength support is not required, the tray maintains a lightweight "day" - shaped structure, which is convenient for transportation and storage; when higher strength and stability are required, by installing the reinforcing plate, a "field" - shaped structure is formed to enhance the compressive resistance and bearing capacity of the tray. Abandon the traditional mode of separately injecting the bottoms of "day" - shaped and "field" - shaped trays. Adopt the design that the initial bottom of the tray is "day" - shaped and is combined with a detachable reinforcing plate to form a "field" - shaped structure. This enables large - scale injection molding equipment to only inject trays with a "day" - shaped bottom, and then inject the reinforcing plate by a small - scale injection molding machine and install the reinforcing plate at the bottom of the tray to cooperate with the original "day" - shaped structure to form a "field" - shaped structure. At the same time, the utilization rate of large - scale injection molding equipment is improved, and the equipment does not need to re - open the mold due to producing trays with different bottom structures, effectively improving the production efficiency and reducing the cost.

[0008] Preferably, the reinforcing plate has protruding structures at both ends, and the support surface has a demolding hole through it along the direction of the support foot. The number of demolding holes is opposite to the number of protruding structures, and the protruding structures are inserted into the demolding holes.

[0009] By adopting the above technical solution, the cooperation between the raised structure and the demolding hole enables the quick and convenient installation of the reinforcing plate and the pallet body. The protruding structure is inserted into the demolding hole, and the contours of the two are matched, which can ensure the accuracy of the installation position of the reinforcing plate and avoid the reinforcing plate from shifting during the installation process. At the same time, it also provides preliminary positioning and fixation for the reinforcing plate, making the installation of the reinforcing plate on the pallet more stable and preventing it from easily shaking or falling off during use, thus ensuring the stability and reliability of the pallet structure.

[0010] Preferably, the support surface has an installation channel in the direction perpendicular to the support foot, and a steel pipe is installed in the installation channel.

[0011] By adopting the above technical solution, the steel pipe possesses high compressive strength and rigidity. After being inserted into the installation channel, it can significantly enhance the pallet's compressive strength and load-bearing capacity. Especially when transporting heavy goods or storing them in multiple layers, the steel pipe can effectively distribute the weight of the goods, preventing the pallet from deforming or being damaged due to excessive pressure. This further improves the pallet's performance and applicability, enabling it to meet the needs of more demanding usage scenarios.

[0012] Preferably, the number of installation channels corresponds to the number of demolding holes, and the installation channels extend through the demolding holes.

[0013] By adopting the above technical solution, the installation channel, which runs through the demolding hole, provides a convenient path for the installation of the steel pipe. This also allows the steel pipe to better connect with the reinforcing plate and the pallet body when passing through the installation channel and the insertion hole, enhancing the overall structural stability. The correspondence between the number of installation channels and demolding holes ensures the stability and uniformity of the connection between the reinforcing plate and the pallet, guaranteeing effective support and fixation at each reinforcing plate installation position and preventing uneven local stress.

[0014] Preferably, the end of the protruding structure away from the reinforcing plate has an insertion hole. When the protruding structure is inserted into the demolding hole, the insertion hole corresponds to the position of the installation channel, and the steel pipe passes through the installation channel and is set with the insertion hole.

[0015] By adopting the above technical solution, the insertion hole and the installation channel are matched in contour and position, allowing the steel pipe inserted into the installation channel to be smoothly inserted into the insertion hole. This precise fit further enhances the installation stability of the reinforcing plate. The steel pipe passes through the insertion hole and the installation channel, connecting the reinforcing plate more tightly to the pallet body, and improving the overall integrity and deformation resistance of the pallet structure. This ensures that when the pallet is bearing heavy loads or subjected to external impacts, the reinforcing plate can stably play its role in reinforcing the structure and will not easily loosen or shift.

[0016] Preferably, a plug is fixedly installed inside the installation channel, and the plug is fixedly installed at the opening of the installation channel.

[0017] By adopting the above technical solution and setting a plug at the opening of the installation channel, the steel pipe can be prevented from sliding or falling off along the installation channel during use, ensuring that the steel pipe is always in the correct installation position and continuously plays the role of strengthening the connection and improving the structural strength.

[0018] Preferably, a fixing hole is provided through the end of the plug, and an installation hole is provided through the end of the support surface. The installation hole corresponds to and communicates with the fixing hole. A fixing pin is provided in the fixing hole and the installation hole, and the fixing pin passes through the installation hole and the fixing hole.

[0019] By adopting the above technical solution, the installation of the fixing pin further strengthens the connection between the end cap and the pallet. The fixing pin passes through the mounting hole and the fixing hole, which firmly fixes the end cap in the installation channel, preventing the end cap from shifting. This ensures the stability of the steel pipe in the installation channel, ensures a solid connection between the reinforcing plate and the pallet, and ultimately improves the overall stability and load-bearing capacity of the pallet structure, enabling the pallet to be used safely and reliably in various usage scenarios.

[0020] Preferably, the interior of the support leg and the bottom wall of the tray are both mesh-like support structures.

[0021] By adopting the above technical solution, the structural strength and stability of the pallet are enhanced by utilizing the mechanical properties of the mesh structure.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By designing the bottom of the tray as a "day" - shaped structure and combining it with a detachable reinforcement plate to form a "field" - shaped structure. When high - strength support is not required, the tray maintains the lightweight "day" - shaped structure, facilitating transportation and storage. When higher strength and stability are needed, by installing the reinforcement plate, a "field" - shaped structure is formed, enhancing the compression resistance and bearing capacity of the tray. Abandoning the traditional mode of separately injecting the bottoms of "day" - shaped and "field" - shaped trays, the design is such that the initial bottom of the tray is "day" - shaped, and a detachable reinforcement plate is used to form a "field" - shaped structure. This enables large - scale injection - molding equipment to only inject trays with a "day" - shaped bottom. Then, a small - scale injection - molding machine is used to inject and form the reinforcement plate, and the reinforcement plate is installed at the bottom of the tray to cooperate with the original "day" - shaped structure to form a "field" - shaped structure. At the same time, the utilization rate of large - scale injection - molding equipment is improved. The equipment does not need to re - mold due to producing trays with different bottom structures, effectively enhancing production efficiency and reducing costs.

[0024] 2. The steel pipe has high compressive strength and rigidity. After being inserted into the installation channel, it can significantly enhance the compression resistance and bearing capacity of the tray. Especially when transporting heavy goods or storing them in multiple layers, the steel pipe can effectively share the weight of the goods, preventing the tray from deforming or being damaged due to excessive pressure, further improving the service performance and application range of the tray, enabling it to meet the requirements of more stringent usage scenarios.

[0025] 3. The insertion holes are adapted to the contour of the installation channel and are in corresponding positions, enabling the steel pipe inserted into the installation channel to smoothly insert into the insertion holes. This precise fit further enhances the installation stability of the reinforcement plate. The steel pipe passes through the insertion holes and the installation channel, connecting the reinforcement plate and the tray body more tightly together, and improving the integrity and anti - deformation ability of the tray structure. When the tray is carrying heavy objects or being impacted by external forces, the reinforcement plate can stably play the role of enhancing the structure and will not easily loosen or shift.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] This application discloses a novel tray.

[0031] A new type of pallet, referring to Figure 1 and Figure 2 The pallet includes a tray 1 and reinforcing plates 2. The tray 1 consists of a support surface 11 and supporting legs 12, which are integrally injection molded. There are nine supporting legs 12, which are evenly distributed on the bottom wall of the support surface 11. Lower reinforcing plates 3 are fixedly installed between adjacent supporting legs 12. The horizontal and vertical lower reinforcing plates 3 are cross-connected at the bottom to form a H-shaped structure. There are two reinforcing plates 2, which are detachably installed on the side of the support surface 11 near the supporting legs 12. The two reinforcing plates 2 are installed horizontally or vertically between the supporting legs 12, forming a Grid-shaped structure together with the original lower reinforcing plates 3, which further improves the load-bearing capacity of the pallet 1.

[0032] Specifically, the interior of the support leg 12 and the bottom wall of the support surface 11 are integrally injection molded into a grid-like support structure. The grid-like structure can effectively distribute the force, improve the compressive and bending resistance of the pallet, and make it less prone to deformation or breakage under heavy loads.

[0033] The lower stiffener 3, the support surface 11, and the support leg 12 enclose a forkhole space for the forklift forks to insert, allowing forklifts to enter from four directions. The side of the lower stiffener 3 closest to the support surface 11 has a forklift ramp 31. When the pallet is transferred by a forklift, the forklift ramp 31 can effectively reduce the contact area between the forklift and the pallet, thereby effectively reducing the collision between the forklift and the pallet and helping to avoid damage to the pallet during forklift handling.

[0034] Specifically, the reinforcing plate 2 has protruding structures 4 at both ends, and a demolding hole 5 is provided through the support surface 11. The tray 1 is integrally injection molded, and the support surface 11 has a pre-reserved demolding hole 5 for demolding. The number of demolding holes 5 and protruding structures 4 are corresponding, and the contours of the protruding structures 4 and demolding holes 5 are adapted to each other. The reinforcing plate 2 is inserted into the demolding hole 5 from the side of the support surface 11 near the support foot 12 through the protruding structures 4, and together with the lower stiffener 3, forms a grid-like structure. When the protruding structure 2 is inserted into the demolding hole 5, the end of the protruding structure 4 away from the reinforcing plate is flush with the support surface 11.

[0035] Furthermore, refer to Figure 2 and Figure 3, insertion holes 41 are provided at one ends of the convex structures 4 away from the reinforcing plate 2. The supporting surface 11 is provided with strip-shaped installation channels 6 perpendicular to the direction of the supporting feet 12. The number of the installation channels 6 corresponds to the number of the demolding holes 5. One end of each installation channel 6 is open, and the other end is closed. Steel pipes 7 are inserted into the installation channels 6, and the installation channels 6 respectively penetrate through the demolding holes 5. When the convex structures 4 of the reinforcing plate 2 are inserted into the demolding holes 5, the insertion holes 41 on the convex structures 4 correspond to the installation channels 6, and then the steel pipes 7 penetrate through the installation channels 6 and the insertion holes 41; the reinforcing plate 2 is firmly installed through the cooperation of the convex structures 4, the demolding holes 5, the insertion holes 41 and the steel pipes 7. The steel pipes 7 not only enhance the fixing effect of the reinforcing plate 2, but also further improve the overall rigidity and bearing capacity of the tray 1, making it more stable in heavy-load scenarios.

[0036] Specifically, the steel pipes 7 are integrally inserted into the installation channels 6, and the length of the steel pipes 7 is less than the length of the installation channels 6. A plug 8 is installed at the opening of the installation channel 6. During specific installation, after the steel pipes 7 are inserted into the installation channels 6, the plug 8 is embedded at the end of the installation channel 6, and the steel pipes 7 are sealed in the installation channels 6 by using the plug 8, effectively preventing the steel pipes 7 from disengaging from the installation channels 6.

[0037] Furthermore, a fixing hole 9 is provided through the plug 8, and an installation hole 10 communicating with the fixing hole 9 is provided through the supporting surface 11. A fixing pin 13 is provided in the fixing hole 9 and the installation hole 10. The fixing pin 13 penetrates through the installation hole 10 and the fixing hole 9 to firmly fix the plug 8 at the end of the installation channel 6. By providing the plug 8 and fixing the plug 8 at the end of the installation pipe through the fixing pin 13, the stability of the steel pipes 7 in the installation channels 6 is ensured, and the steel pipes 7 are prevented from shifting or disengaging during use.

[0038] The implementation principle of the application embodiment is as follows: By designing the bottom of the tray 1 into a square structure with a cross in the middle, and combining it with a detachable reinforcing plate 2 to form a structure like a Chinese character "田" (field), when high-strength support is not required, the tray 1 maintains a light square structure with a cross in the middle, which is convenient for transportation and storage; while when higher strength and stability are required, by installing the reinforcing plate 2 to form a structure like a Chinese character "田" (field), the compressive resistance and bearing capacity of the tray 1 are enhanced.

[0039] Abandon the traditional mode of separately injecting the bottom of the rectangular and cross-shaped trays 1. Instead, adopt a design where the bottom of the tray 1 is initially rectangular, and a detachable reinforcing plate 2 is used to form a cross shape. This allows large injection molding equipment to only inject the tray 1 with a rectangular bottom. Then, a small injection molding machine is used to inject and form the reinforcing plate 2, and the reinforcing plate 2 is installed at the bottom of the tray 1 to cooperate with the original rectangular structure to form a cross-shaped structure. At the same time, the utilization rate of the large injection molding equipment is improved. The equipment does not need to re-open the mold due to the production of trays 1 with different bottom structures, effectively improving the production efficiency and reducing the cost.

[0040] The above are all preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
