Description

Technical Field

[0001] The utility model relates to the technical field of storage and transportation attachment devices in cold chain logistics, in particular to a stackable combined pallet used for cold chain storage and transportation. Background Art

[0002] Goods transported in cold chain are usually packed in EPS foam boxes, cartons or sacks. This form of packaging is time-consuming, labor-intensive and costly if loaded and unloaded manually. In addition, there is not enough space between the goods for cold air circulation. In order to facilitate mechanical handling and loading and unloading, metal frame equipment is often used. Although forklifts and other machinery can be used to improve loading and unloading efficiency and reduce some costs, such metal frame equipment often uses welding to form a fixed frame structure.

[0003] A Chinese patent discloses a forklift pallet for transportation (authorization announcement number CN 220432257 U). The patented technology can adjust the position of the limit rod, and the limit rod can be fixed after adjustment, so as to provide better protection for smaller goods on the pallet and effectively prevent the goods from falling off the pallet. However, the height of the device is a fixed value and cannot be adjusted as needed, and the maintenance cost is high after the device is damaged. At the same time, in order to prevent the goods stored in the device from scattering and falling out, a disposable film is often wrapped around the outside of the device, which is not conducive to the circulation of cold air and increases additional costs. Therefore, the utility model provides a stackable modular pallet for cold chain storage and transportation to solve the problems raised in the above-mentioned background technology.
