[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] like Figure 1 and Figure 2 As shown, an adjustable food handling tray includes an outer shell 1, inside which a connecting plate 2 is movably provided. A sealing structure 3 is movably provided inside the other end face of the connecting plate 2. The outer shell 1 is not liftable. Limiting grooves 4 are integrally connected to both sides of the connecting plate 2. Sliding limiting rods 5 corresponding to the limiting grooves 4 are fixedly connected to the ends of the connecting plate 2 and the sealing structure 3 near the outer shell 1. The outer shell 1 is also provided with a locking groove 6 corresponding to the limiting grooves 4 on the connecting plate 2. The locking groove 6 penetrates the outer plate of the outer shell 1, and the limiting grooves 4 of the outer shell 1 are located at its bottom. The connecting plate 2 is located inside the outer shell 1, and the limiting grooves 4 on it are located in the middle of the two side walls. The locking grooves 6 are located in the middle of the side plates of the outer shell 1. An inclined surface 10 is also provided at the opening of the outer shell 1 near the connecting plate 2 to allow the connecting plate 2 to rotate within a certain range.

[0024] In this implementation scheme, the outer shell 1, connecting plate 2, sealing structure 3, limiting groove 4, sliding limiting rod 5, engaging groove 6, and inclined surface 10 cooperate with each other to realize the adjustable expansion of the tray and the convenient food unloading function.

[0025] First, the limiting groove 4 of the outer shell 1 is located at its bottom. This position allows the sliding limiting rod 5 on the connecting plate 2 and the sealing structure 3 to provide a stable support point for the longitudinal expansion of the pallet when inserted into the limiting groove 4. When the sliding limiting rod 5 slides along the limiting groove 4, the longitudinal position of the connecting plate 2 and the sealing structure 3 relative to the outer shell 1 can be adjusted, realizing the adjustability of the pallet in the longitudinal dimension to adapt to the needs of food packaging or stacking of different heights.

[0026] The limiting grooves 4 located in the middle of the side walls on both sides of the connecting plate 2 provide a key structure for the lateral rotation of the sealing structure 3. The sliding limiting rod 5 on the connecting plate 2 cooperates with the engaging groove 6 on the outer shell 1. The engaging groove 6 penetrates the outer plate of the outer shell 1 and is located in the middle of the side plate. When the sliding limiting rod 5 engages with the engaging groove 6, it restricts the excessive lateral movement of the connecting plate 2, ensuring its positional stability after lateral adjustment. At the same time, the rotation of the connecting plate 2 within a certain range is achieved by means of the inclined surface 10 near one end of the outer shell 1. The inclined surface 10 provides guidance and limiting for the rotation of the connecting plate 2, preventing the connecting plate 2 from rotating excessively and detaching from the outer shell 1, ensuring its stability during rotation. After the connecting plate 2 rotates at a certain angle, it can serve as a conveying track, facilitating the rapid conveying of food in a specific direction.

[0027] The movable plate 7 in the sealing structure 3 has a notch 9 at one end near the connecting plate 2. This notch 9 allows the movable plate 7 to rotate smoothly to an angle perpendicular to the ground, effectively supporting the overall structure. After the sealing structure 3 rotates a certain angle, the sealing plate 8 can act as a support surface, working in conjunction with the rotated connecting plate 2 to form an inclined channel that facilitates rapid food unloading, greatly improving the efficiency and convenience of food loading and unloading. This unique structural design not only realizes the multi-functionality of the pallet during loading and unloading but also enhances its flexibility and adaptability in practical applications, reducing losses and labor intensity during food loading and unloading.

[0028] like Figure 3 and Figure 4As shown, in the aforementioned adjustable tray for food loading and unloading, the sealing structure 3 is quite crucial. It includes a movable plate 7 located inside the connecting plate 2, and a sealing plate 8 fixedly connected to the other end of the movable plate 7. The middle section of the movable plate 7 is fixedly connected to the corresponding sliding limit rod 5. A notch 9 is provided on the end of the movable plate 7 near the connecting plate 2. This design allows the movable plate 7 to rotate, thereby effectively completing the sealing task. With the coordinated operation of the outer shell 1, the connecting plate 2, and the sealing structure 3, the tray can be flexibly adjusted to meet different food loading and unloading needs, ensuring the efficiency and stability of the food loading and unloading process.

[0029] In this embodiment, the outer shell 1 is typically made of high-strength, lightweight aluminum alloy, with a length of 1.2m, a width of 0.8m, and a height of 0.3m, to accommodate most food handling scenarios. The connecting plate 2 is also made of aluminum alloy, with a length of 0.7m, a width of 0.6m, and a thickness of 0.05m. The limiting groove 4 in the middle of its two side walls is typically a long strip groove, with a length of 0.5m, a width of 0.03m, and a depth of 0.02m. The sliding limiting rod 5 is made of stainless steel, with a diameter of 0.02m and a length of 0.1m, and its two ends are fixed to the connecting plate 2 and the capping structure 3 by threaded connections. The engaging groove 6 is a square through hole penetrating the outer side plate of the outer shell 1, with a side length of 0.03m, located in the middle of the side plate of the outer shell 1, 0.15m from the bottom. The inclined plane 10 has an inclination angle of 30 degrees and a width of 0.1m, which provides guidance and limit for the rotation of the connecting plate 2.

[0030] The movable plate 7 in the sealing structure 3 is made of high-strength plastic, with a length of 0.5m, a width of 0.4m, and a thickness of 0.03m. Its middle section is fixedly connected to the sliding limit rod 5, typically by bolts. The sealing plate 8 is made of the same plastic material as the movable plate 7, with a length of 0.3m, a width of 0.4m, and a thickness of 0.03m. It is fixedly connected to the other end of the movable plate 7, also by bolts. The notch 9 is a rectangular notch with a length of 0.2m and a width of 0.03m, located at the end of the movable plate 7 near the connecting plate 2, so that the movable plate 7 can rotate smoothly to an angle perpendicular to the ground.

[0031] In its stored state within the transfer vehicle, the connecting plate 2 is located inside the outer shell 1, with its limiting groove 4 aligned with the engaging groove 6 on the outer shell 1. The sliding limiting rod 5 engages in the engaging groove 6, maintaining the stability of the connecting plate 2. When the sealing structure 3 is closed, the movable plate 7 and the sealing plate 8 fit tightly against the inside of the end face of the connecting plate 2. The notch 9 cooperates with the inclined surface 10 of the outer shell 1, making the entire pallet structure compact and facilitating the storage and transportation of food in the transfer vehicle.

[0032] When rapid food unloading is required, the sliding limit rod 5 is first pulled out of the locking groove 6. Then, the connecting plate 2 is rotated around the inclined surface 10 near one end of the outer shell 1 at a certain angle, usually 60 degrees, to form a conveyor track. At the same time, the movable plate 7 in the sealing structure 3 is rotated through the notch 9 to an angle perpendicular to the ground. The sealing plate 8, as a support surface, works in conjunction with the rotated connecting plate 2 to form an inclined channel. Food can quickly slide down along this channel to the ground or a designated collection area, greatly improving the efficiency of food unloading.

[0033] When using this device, first place the food on the outer shell 1. At this time, the connecting plate 2 is located inside the outer shell 1, and its limiting groove 4 is aligned with the engaging groove 6 on the outer shell 1. The sliding limiting rod 5 is engaged in the engaging groove 6 to keep the connecting plate 2 stable. The sealing structure 3 is closed, and the movable plate 7 and the sealing plate 8 are tightly fitted inside the end face of the connecting plate 2. The notch 9 cooperates with the inclined surface 10 of the outer shell 1, making the entire pallet structure compact and convenient for storing and transporting food in a transfer vehicle. When unloading is required, first pull the sliding limiting rod 5 out of the engaging groove 6, and then rotate the connecting plate 2 around the inclined surface 10 near one end opening of the outer shell 1 by a certain angle to make it a conveying track. At the same time, rotate the movable plate 7 in the sealing structure 3 through the notch 9 to an angle perpendicular to the ground. The sealing plate 8, as a support surface, works in conjunction with the rotated connecting plate 2 to form an inclined channel. The food can slide quickly along this channel to the ground or a designated collection area, completing the rapid unloading.

[0034] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
