Description

Technical Field

[0001] This utility model relates to the field of logistics transportation, specifically to an adjustable length pallet. Background Technology

[0002] In manufacturing plants, pallets are essential tools for material handling and storage. They play a crucial role in all stages of the process, from raw material entry, semi-finished product transfer during production, to finished product stacking and shipping.

[0003] Pallets enable rapid loading, unloading, and stacking of goods, significantly improving logistics efficiency, shortening logistics cycles, and reducing labor costs. Currently, pallets on the market are broadly categorized by material into wooden pallets, plastic pallets, and steel pallets. From a cost perspective, wooden pallets are more economical in terms of material cost and manufacturing process, making them more suitable for export-oriented enterprises.

[0004] Because goods vary in size and shape, outer box dimensions differ, and these dimensions are a decisive factor in determining the size of wooden pallets. For example, in European countries, the required pallet dimensions for racking (1200×800mm) are different from the standard pallet dimensions in China (1200×1000mm).

[0005] Currently, the manufacturing process for wooden pallets prevents flexible size adjustments after processing, leading to the following consequences: 1. The availability of various pallet sizes cannot meet the needs of all countries and regions; 2. Pallet suppliers are unable to mass-produce and process pallets, resulting in untimely delivery; 3. Low utilization rate of pallet-loading container space; 4. Increased ocean freight costs. Utility Model Content

[0011] An elastic element is disposed inside the inner tube. One end of the elastic element is provided with a locking block. The elastic element has an elastic force, which is used to apply force to insert the locking block into the first positioning hole and the second positioning hole to fix the inner tube.

[0012] The elastic element is a spring sheet.

[0013] The elastic element has a V-shaped structure.

[0014] The elastic element is provided with the locking block at both the top and bottom.

[0015] The card block includes a column and an arc-shaped surface on the outer wall of the top of the column, the arc-shaped surface being used to slide and engage with the inner wall of the first positioning hole.

[0016] The support plates are provided on both sides of the substrate.

[0017] The substrate includes a first plate and a first base, and the outer tube is disposed on the first base.

[0018] The support plate includes a second plate and a second base, and the inner tube is disposed on the second base.

[0019] The beneficial effects of this utility model are: This utility model provides an adjustable length tray, which can be adjusted to meet different usage needs and is applicable to a variety of scenarios. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings. An adjustable-length tray includes a base plate 1 and a support plate 2, and an outer tube 3 disposed on the outer side wall of the base plate. The outer tube has a plurality of through-holes 31 arranged radially. An inner tube 4 is disposed on the outer side wall of the support plate, at least a portion of which is located within the outer tube and has through-holes 41 arranged radially. The inner tube and the outer tube are slidably fitted together. An elastic element 5 is disposed inside the inner tube, with a locking block 51 at one end. The elastic element has an elastic force, which is used to apply force to insert the locking block into the first and second positioning holes to fix the inner tube. The locking block extends out of the outer tube due to the elastic force of the elastic element, with part of it located in the first positioning hole and part in the second positioning hole. Therefore, the inner tube cannot slide relative to the outer tube. When length adjustment is required, a finger is pressed down on the locking block to move it out of the first positioning hole, and then the support plate is pulled.

[0025] In this embodiment, as shown in the figure, the elastic element is a spring sheet.

[0026] In this embodiment, as shown in the figure, the elastic element has a V-shaped structure.

[0027] In this embodiment, as shown in the figure, the elastic member is provided with the locking block at both the top and bottom.

[0028] In this embodiment, as shown in the figure, the locking block includes a column 53 and an arc-shaped surface 52 on the outer wall of the top of the column. The arc-shaped surface is used to slide and engage with the inner wall of the first positioning hole. When the support plate is pulled after being pressed down, the arc-shaped surface engages with the inner wall of the first positioning hole, which will continue to drive the locking block down. In this way, it is not necessary to press the locking block down very low with your finger.

[0029] In this embodiment, as shown in the figure, the support plates are provided on both sides of the substrate. Both sides are adjustable, which is quite convenient.

[0030] In this embodiment, as shown in the figure, the substrate includes a first plate and a first base 12, and the outer tube is disposed on the first base.

[0031] In this embodiment, as shown in the figure, the support plate includes a second plate body and a second base 22, and the inner tube is disposed on the second base.
