Description

A stretchable, adjustable-size tray Technical Field

[0001] This invention relates to the field of pallet technology, and more particularly to a stretchable, adjustable pallet. Background Technology

[0002] Pallets possess numerous advantages, including robust and durable structure, standardization and interoperability, versatility and adaptability, environmental friendliness and sustainability, identification and traceability, and improved logistics efficiency, making them indispensable in logistics, warehousing, and transportation. Currently, stretch pallets allow for adjustment of their dimensions, thus modifying the overall usable area. However, the connection and stability between the pallet body and the stretching element are still relatively poor.

[0003] In view of this, we propose a stretchable, adjustable-size tray to solve the existing problems. Summary of the Invention

[0006] Furthermore, four steel pipes are provided on each side of the pallet body, and four steel pipe sliding holes are provided on one side of each stretching body.

[0007] Furthermore, the eight steel pipes and the eight steel pipe sleeve sliding holes are arranged in a one-to-one correspondence.

[0008] Furthermore, the sliding hole of the steel pipe sleeve is a concave hole into which the steel pipe is inserted.

[0009] Furthermore, the steel pipe is connected to the sliding hole and the steel pipe by a sliding installation method.

[0010] Furthermore, the raised snap fasteners and the circular holes are connected in an interlocking manner.

[0011] Furthermore, the tray body and the stretching body are connected in a serrated nesting manner.

[0012] Furthermore, the bolt can rotate 180 degrees.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This invention features a tension body on each side of the pallet body, and symmetrical steel pipes on both sides of the pallet body. The steel pipes possess excellent compressive and tensile strength, can withstand high internal and external pressures, and resist oxidation and corrosion, extending their service life. A sliding hole for the steel pipe is provided on one side of the tension body for easy connection with the steel pipe. A tight fit is achieved through sliding, ensuring the stability and reliability of the connection. Raised snap-fit ​​points are provided on the side wall surface of the tension body, and circular holes are provided on the side wall surface of the pallet body for easy installation and disassembly of the pallet. This ensures a firm connection between the pallet body and the tension body, preventing detachment. Bolts are provided on the upper surfaces of the pallet body and the tension body as fixing devices for the sliding holes and steel pipes, preventing displacement or detachment during use. This invention not only simplifies the installation process and improves installation efficiency but also enhances durability and safety, facilitates maintenance and replacement, and strengthens adaptability and flexibility.

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] As shown in Figures 1, 2, 3 and 4, a stretchable adjustable pallet includes a pallet body 1, with a stretching body 2 on each side of the pallet body 1, which adjusts the size by stretching the pallet in the width direction.

[0033] As shown in Figures 5, 6 and 7, steel pipes 3 are symmetrically arranged on both sides of the pallet body 1, and steel pipe sliding holes 4 are provided on one side of the tensioning body 2. Four steel pipes 3 are provided on each side of the pallet body 1, and four steel pipe sliding holes 4 are provided on one side of each tensioning body 2. The eight steel pipes 3 and eight steel pipe sliding holes 4 are arranged in a one-to-one corresponding positional relationship. The steel pipe sliding hole 4 is a concave hole for fitting the steel pipe 3, and the steel pipe sliding hole 4 and the steel pipe 3 are connected by a sliding installation method.

[0034] As shown in Figure 8, the side wall surface of the stretching body 2 is provided with a protruding buckle 5, and the side wall surface of the tray body 1 is provided with a circular hole 6. The protruding buckle 5 and the circular hole 6 are connected in an interlocking manner. When the stretching body 2 is stretched to the position shown in Figure 9, the protruding buckle 5 is released and locked in place with the circular hole 6 of the tray body 1 to keep the stretching stroke fixed.

[0035] Bolts 7 are provided on the upper surfaces of the pallet body 1 and the stretching body 2. The rotation range of bolts 7 is 180 degrees. Bolts 7 fix the pallet size after expansion and contraction by rotating 180 degrees.

[0036] The operation procedure is as follows: Rotate bolt 7 180 degrees to the right, stretch the two stretching bodies 2 to the sides, and insert them into the circular hole 6 to complete the stretching of the tray. Rotate bolt 7 180 degrees in the opposite direction to lock the stretching body 2 and the tray body 1. When the stretching body 2 and the tray body 1 are not locked, bolt 7 is in the state of bolt 7 in the upper part of Figure 10. When the stretching body 2 and the tray body 1 are locked, bolt 7 is in the state of bolt 7 in the lower part of Figure 10.

[0037] The tray body 1 and the stretching body 2 adopt a serrated nested structure. After the combination, the surface is beautiful and there are no holes. The fully unfolded state is shown in Figure 11, the surface contact state is shown in Figure 12, the state at the maximum stretch position is shown in Figure 13, and the fully fitted state without stretching is shown in Figure 14.

[0038] The working principle of a stretchable adjustable tray based on Embodiment 1 is as follows:

[0039] The pallet body 1 is fitted with steel pipes 3, and concave holes are provided in the tension body 2 to facilitate the insertion of 4 steel pipes 3 on the pallet body 1 during expansion and contraction. The sliding sleeve is installed through the holes in the tension body 2 to achieve the closed state.

[0040] Among them, the steel pipe 3 has excellent compressive and tensile strength and can withstand high internal and external pressure. It can also resist oxidation and corrosion, extending its service life. A steel pipe sleeve sliding hole 4 is provided on one side of the tension body 2, which facilitates connection with the steel pipe 3. A tight fit is achieved through sliding, ensuring the stability and reliability of the connection. A protruding buckle 5 is provided on the side wall surface of the tension body 2, and a circular hole 6 is provided on the side wall surface of the pallet body 1, which facilitates the installation and disassembly of the pallet. This ensures a firm connection between the pallet body 1 and the tension body 2 and prevents it from falling off. Bolts 7 are provided on the upper surface of the pallet body 1 and the tension body 2, which serve as fixing devices for the sliding hole and the steel pipe 3, preventing displacement or falling off during use. This not only simplifies the installation process and improves installation efficiency, but also enhances durability and safety, and facilitates maintenance and replacement, thereby increasing adaptability and flexibility.
