[0031] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0032] This pallet body is used to place goods, such as materials used in construction projects, and is usually used in conjunction with forklifts to facilitate the placement and transportation of goods. However, currently, pallets are usually made of wood and have a simple structural design. Due to the heavy goods placed on them, the pallets are easily damaged during the movement and transportation with forklifts, causing the goods to scatter and affecting the safety of the load. In addition, existing pallets are easily affected by weather and storage environment, such as mold or freezing during storage. The overall product scrap rate is high, and they are usually disposable items that are difficult to recycle and reuse, which is not suitable for the green development of the packaging and transportation industry.

[0033] To address the problems of existing trays, this embodiment provides a reusable, separable polymer tray, such as... Figure 1-11 As shown, the main improvement is to make it into a split structure, thereby reducing the overall product scrap rate, facilitating partial replacement and maintenance, thereby reducing the procurement cost of this product, and promoting green development in this field.

[0034] The pallet body 000 includes a detachably connected top portion 100 and a bottom portion 200, such as... Figure 1 As shown, detachable connection methods include snap-fit ​​connections, threaded connections, etc. In this embodiment, a plug 230 is used for insertion. The specific structure is described in detail below. A gap is provided between the top 100 and the bottom 200 of the tray, and forks 010 that can be linearly connected are provided on opposite sides of the tray body 000. Figure 6 As shown; in addition, fork openings 010 can be provided on any two opposite sides. For example, all four sides of this embodiment are provided with fork openings 010. During use, a forklift can be used to select and insert from any side, which improves the ease of use.

[0035] The tray body 000 of this embodiment is made of a polymer material synthesized from polypropylene resin and long glass fibers. It has good low temperature resistance, corrosion resistance, pollution resistance, freeze resistance and load-bearing capacity. Its tensile strength reaches 65MPa-90MPa, flexural strength reaches 70MPa-20MPa, flexural modulus reaches 3000MPa-4500MPa, and heat resistance temperature can reach 135℃-145℃. By restricting the mutual movement between the polymer chains of PP plastic, the shrinkage rate is reduced, thereby improving the material's rigidity, impact resistance, tensile strength, compressive strength, flexural strength and flame retardancy.

[0036] In this embodiment, the top surface of the tray top 100 is provided with a plurality of evenly spaced drainage strips 111, which can enhance drainage performance and reduce the impact on the load-bearing goods. Below this, a downwardly extending first connecting portion is provided, and on the bottom surface of the tray bottom 200, at a corresponding position to the first connecting portion, an upwardly extending first mating portion is provided, such as... Figure 4 and5 As shown, in this embodiment, the first mating part is a plug 230 and the first connecting part is a slot 130, and the two can be plugged into each other one by one.

[0037] To improve the stability of the spacing between the top surface of the support 100 and the bottom surface of the support 200, such as Figure 2 and 3 As shown, a downwardly extending connecting column 120 is provided at the top 100 of the support, and a corresponding connecting bottom 220 is provided at the bottom 200 of the support. Both the connecting column 120 and the connecting bottom 220 have multiple staggered supporting plates 221 inside, such as... Figure 5 As shown, a mounting hole 222 is provided at the intersection of the support plate 221, and the insert post 230 can be installed in the mounting hole 222.

[0038] To ensure accuracy when the forklift inserts into the fork slot 010, an inclined bottom surface 011 is provided on the lower outer side of the fork slot 010. This inclined bottom surface gradually slopes upwards from the outside inwards, and an extension platform 012, flush with its upper surface and extending inwards, is connected to the inclined bottom surface 011. Figure 2 As shown, a symmetrical inclined bottom surface 011 can also be provided on its inner side, and the interior of the extended platform 012 is a cross-connected support plate 013, which improves the overall structural stability and reduces the weight of the product.

[0039] like Figure 4 As shown, the support bottom 200 includes an outer frame 211 and a connecting beam 212 located inside it. In this embodiment, it is shaped like a grid. The outer frame 211 is square, and the connecting beam 212 inside it is vertically connected. The two ends of the connecting beam 212 are respectively connected to the side of the corresponding outer frame. A connecting bottom 220 is provided at its connection point and at the four corners of the outer frame.

[0040] Optionally, a removable panel 240 can be installed in the area between the outer frame and the connecting beam 212, such as... Figure 7-9 As shown, its upper surface is flush with the upper end of the fork opening 010, thus enhancing the load-bearing capacity of the support base 200. Furthermore, multiple interlocking support plates 221 can be installed below the detachable panel 240. The support plates 221 are made of a composite material composed of polyethylene, carbon fiber, and fiberglass panels. The detachable connection method of the detachable panel 240 is not limited; for example, it can be connected by snap-fit ​​or threaded connection.

[0041] The top of the pallet 100 is preferably provided with an anti-slip texture, which can increase the friction between the load and the top of the pallet 100, reduce the probability of the load falling off during handling, and improve safety performance. Figure 10-11 As shown, the connecting column 120 below the top 100 is also equipped with multiple staggered support plates 221, which can effectively reduce the weight of the product while improving structural stability.
