Description

Technical Field

[0001] This utility model relates to the field of logistics transportation and warehousing equipment technology, specifically an adjustable-size pallet. Background Technology

[0002] Pallets are an important tool in modern logistics and warehousing. Their core function is to transform static goods into dynamic goods, enabling efficient, standardized, and safe logistics operations. Pallets form standardized units by carrying goods, making them easy to use with forklifts, racks, and other equipment, thus greatly improving loading and unloading efficiency. They can also reduce collisions and wear during transportation, and are particularly effective in protecting fragile goods (such as glass and precision instruments).

[0003] However, existing national standard pallets and European standard pallets are mostly fixed in size at 1200×800mm, which cannot solve the problem of optimal utilization of container placement. This leads to the problem of wasted container space in pallet stacking. Taking a 40-inch standard container as an example, 24 standard pallets of 1200×800mm can be placed optimally. Inflatable bags are also needed to fill the gaps in the middle. As a result, it cannot adapt to the needs of goods of different sizes, resulting in low transportation efficiency.

[0019] Please see Figures 1-5 In this embodiment of the utility model, an adjustable size tray includes a tray body 1, and both ends of the tray body 1 are slidably connected to a sliding module 2 via a set of slide rails 3.

[0020] exist Figure 1 and Figure 2 In the sliding module 2, there are several extension strips 21. A support leg 25 is fixedly connected to the lower side of one end of each extension strip 21. A sliding groove 22 is fixedly connected to the front and rear sides of each support leg 25. A stainless steel ball-head spring plunger 23 and a positioning hole 24 are installed inside each sliding groove 22. A slide rail 3 is slidably connected to the inner side of the corresponding sliding groove 22. The slide rail 3 has a matching structure for the stainless steel ball-head spring plunger 23 and the positioning hole 24. For example, the stainless steel ball-head spring plunger 23 on the slide rail 3 corresponds to the positioning hole 24 on the sliding groove 22. Hole 24 corresponds to the stainless steel ball spring plunger 23 on the slide body 22; when the sliding module 2 slides along the pallet body 1 and reaches the set position, the stainless steel ball spring plunger 23 on the slide rail 3 enters the positioning hole 24 on the slide body 22, thereby achieving automatic locking; ensuring the stability of the pallet body 1 and the sliding module 2, and adjusting the length of the entire pallet to meet the needs of the container's internal space, suitable for handling and storing goods of different sizes, maximizing the utilization rate of the container.

[0021] exist Figure 3 and Figure 4In the process, the stainless steel ball spring plunger 23 includes a plunger housing 231 and a sliding ball head 235 slidably connected to the inner side of the plunger housing 231. The rear end of the plunger housing 231 is fixedly connected to a sealing plate 238 by screws. After loosening the screws counterclockwise, the sealing plate 238 can be removed, thereby allowing the sliding ball head 235 and other structures to be disassembled. A spring 236 is installed inside both the plunger housing 231 and the sliding ball head 235. The front end of the sliding ball head 235 has a countersunk groove 234, and a preload adjustment component 233 is installed through the inner side of the countersunk groove 234. When the slide rail 3 slides inside the slide groove 22, the slide rail 3 presses on the sliding ball head 235, and the sliding ball head 235 slides towards the inner side of the plunger housing 231, compressing the spring 236. When the positioning hole 24 on the slide rail 236 reaches the sliding ball head 235, the spring 236 returns to its original position, and the sliding ball head 235 slides outward from the plunger housing 231. At this time, the sliding ball head 235 enters the positioning hole 24 on the slide rail 3, and the slide rail 3 and the sliding module 2 are locked together and no longer move. When the sliding module 2 is pulled in the opposite direction, the sliding ball head 235 overcomes the pressure of the spring 236 and exits the positioning hole 24, and the sliding module 2 resumes its sliding function. A fixing plate 237 is provided at the rear end of the inner side of the spring 236, and a fixing bolt 232 is installed through the inner side of the fixing plate 237. The spring 236 is fixedly installed on the sealing plate 238 through the fixing plate 237 and the fixing bolt 232, so that the spring 236 remains stable and will not shift.

[0022] exist Figure 3 and Figure 5 In the process, the preload adjustment assembly 233 includes an adjustment plate 2331. The front end of the adjustment plate 2331 is fixedly connected to a rotating sleeve 2332. The front end of the inner side of the rotating sleeve 2332 is rotatably connected to an adjustment screw 2333. Both the adjustment plate 2331 and the rotating sleeve 2332 are located inside the sliding ball head 235. The adjustment screw 2333 engages and penetrates the inner side of the countersunk groove 234. When the adjustment screw 2333 is rotated, the adjustment screw 2333 rotates inside the rotating sleeve 2332 and pushes or pulls the adjustment plate 2331, adjusting the position of the adjustment plate 2331 inside the sliding ball head 235. By changing the distance between the adjustment plate 2331 and the plunger shell 231, the preload of the spring 236 is adjusted.

[0023] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
