Description

Technical Field

[0001] This utility model relates to the field of plastic pallet manufacturing technology, specifically a plastic pallet structure. Background Technology

[0002] In warehousing and logistics across many industries, materials are stacked on pallets to facilitate forklift transport. Depending on the material, there are wooden pallets, bamboo pallets, and plastic pallets. Plastic pallets are the most widely used due to their ease of processing and low processing costs.

[0003] Existing plastic pallets are injection molded from plastic materials. However, due to the heavy weight of stacked materials and the inevitable bumps and knocks during stacking and use, coupled with the aging process over time, existing plastic pallets have a high damage rate, leading to increased warehousing costs. Furthermore, pallets sometimes break in half during forklift transfers, causing material spillage, economic losses, and even posing a risk to the personal safety of on-site personnel. Therefore, the structure of existing plastic pallets needs further improvement. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned deficiencies and to disclose to the public a plastic pallet structure that is simple and reasonable in structure, easy to process, strong, and long in service life.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A plastic pallet structure includes a pallet body, which is an integral structure formed by injection molding. The pallet body is provided with a metal pipe insertion groove, at least one end of which is provided with a metal pipe insertion port, and a metal pipe is provided inside the metal pipe insertion groove.

[0007] Further optimization measures for this technical solution are as follows:

[0008] As an improvement, both ends of the metal tube insertion slot are provided with metal tube insertion ports. This design can improve assembly efficiency.

[0009] As an improvement, an end plug is provided at the insertion port of the metal tube.

[0010] As an improvement, a limiting part is formed on the tray body by cooling and shrinking at the metal tube insertion port.

[0011] As an improvement, the metal tube is arranged along the length direction of the pallet body or along the width direction of the pallet body.

[0012] As an improvement, the metal tube adopts a square tube structure. Square tubes have better bending resistance than round tubes, and can better prevent the plastic pallet from breaking.

[0013] As an improvement, the main body of the pallet has a grid-like structure, and vertical grid-type reinforcing ribs are provided on the back of the main body. The grid-like structure of the main body reduces the weight of the pallet, while the grid-type reinforcing ribs increase its strength.

[0014] As an improvement, the pallet body is integrally formed with support legs, and the support legs have recessed cavities. This design of support legs with internal cavities allows plastic pallets to be nested and stacked together, reducing storage space.

[0015] As an improvement, the bottom of the support leg is provided with drainage holes. These drainage holes prevent rainwater from accumulating in the recesses of the support leg during outdoor use.

[0016] As an improvement, the edge of the tray body is provided with a retaining edge.

[0017] The advantages of this utility model compared with the prior art are:

[0018] This utility model discloses a plastic pallet structure that is simple and reasonable. By incorporating a metal tube into the integrally injection-molded pallet body, the strength of the plastic pallet can be improved without changing the original processing method. In particular, it can improve the fracture resistance of the plastic pallet, thereby extending its service life. Attached Figure Description

[0027] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0028] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0029] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0030] like Figures 1 to 5 As shown, a plastic pallet structure includes a pallet body 1, which is an integral structure formed by injection molding. The pallet body 1 is provided with a metal pipe insertion groove 11, at least one end of which is provided with a metal pipe insertion port, and a metal pipe 2 is provided in the metal pipe insertion groove 11.

[0031] The aforementioned metal pipe 2 can be a steel pipe, iron pipe, etc.

[0032] Both ends of the metal tube insertion slot 11 are provided with metal tube insertion ports. Providing metal tube insertion ports at both ends facilitates assembly and improves assembly efficiency.

[0033] An end plug 3 is provided at the insertion port of the metal tube.

[0034] The tray body 1 has a limiting part 11a formed by cooling and shrinking at the metal tube insertion port.

[0035] During processing, the pallet body 1 is injection molded. Before the pallet body 1 cools down, the metal tube 2 is inserted from the metal tube insertion port into the metal tube insertion groove 11 of the pallet body 1. After insertion, the end plug 3 is placed outside the metal tube 2 from the metal tube insertion port. After the pallet body 1 cools down, due to thermal expansion and contraction, the pallet body 1 will naturally shrink at the metal tube insertion port to form a limiting part 11a, thereby sealing the end plug 3 and the metal tube 2 in the metal tube insertion groove 11.

[0036] In this embodiment, the metal tube 2 is arranged along the length direction of the pallet body 1; of course, the metal tube 2 can also be arranged along the width direction of the pallet body 1.

[0037] The metal tube 2 mentioned above adopts a square tube structure. Both square and round tubes are readily available tubular materials. For tubes of the same specifications and materials, square tubes have better bending resistance than round tubes. The use of a square tube structure here can better prevent the plastic pallet from breaking.

[0038] The main body of the pallet body 1 has a grid-like structure, and vertical grid-type reinforcing ribs 12 are provided on the back of the main body of the pallet body 1. The grid-like structure of the main body of the pallet body 1 can reduce the weight of the pallet, while the grid-type reinforcing ribs 12 can increase the strength of the pallet.

[0039] The pallet body 1 is integrally formed with a support leg 13, and the support leg 13 has a cavity 13a. By providing the support leg 13 with the cavity 13a, when plastic pallets are stacked, the support leg 13 of the upper layer of plastic pallets is inserted into the cavity 13a of the lower layer of plastic pallets, realizing nested stacking of plastic pallets, which can greatly reduce the stacking space.

[0040] The bottom of the support leg 13 is provided with a drainage hole 13b.

[0041] The pallet body 1 is provided with a retaining edge 14. The retaining edge 14 can block the materials on the plastic pallet to a certain extent and prevent them from falling off the plastic pallet.

[0042] This utility model discloses a plastic pallet structure that is simple, reasonable, and easy to manufacture. By setting a metal tube 2 inside the integrally injection-molded pallet body 1, the strength of the plastic pallet can be improved without changing the original processing method, especially the fracture resistance of the plastic pallet, thereby increasing the service life of the plastic pallet.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
