Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a portable telescopic cabinet. Background Art

[0002] A telescopic cabinet (also known as a telescopic storage cabinet, adjustable storage cabinet, etc.) is a storage solution that can be adjusted in size or shape according to needs. Such storage cabinets are usually designed to be expandable or contractible to adapt to different space requirements or item sizes. Telescopic cabinets are commonly found in places such as kitchens, bathrooms, and offices where space needs to be utilized efficiently, and they are flexible and versatile, suitable for a variety of applications, such as storing clothes, documents, kitchen utensils, etc.

[0003] Existing telescopic cabinets have the effect of telescopic expansion. However, in order to ensure the realization of the telescopic function during use, telescopic cabinets are often made of relatively light materials, which may affect their load-bearing capacity. And usually after expansion, the expanded plate body does not have a structure with enhanced support function. If too heavy items are placed, it may cause deformation or damage. For this reason, the inventor has proposed a portable telescopic cabinet to solve the above-mentioned technical problems. Summary of the Utility Model
