Description

Technical Field

[0001] The invention relates to the technical field of drawer cabinets, and in particular to a drawer cabinet with a lifting structure and a use method thereof. Background Art

[0002] A chest of drawers is a cabinet composed of N drawers. Cabinets can be divided into three types according to the cabinet structure: single cabinets, combination cabinets, and hanging cabinets. Single cabinets have relatively simple functions, such as wardrobes, filing cabinets, food cabinets, etc. Combination cabinets can be combined in various ways according to usage requirements and environmental conditions, and have multiple functions such as storage, display, and support; there are two types of combinations: single cabinet combination and component combination. Single cabinet combination consists of a series of single cabinets, which are combined in three ways: stacking, multi-directional, and parallel according to a certain size ratio; component combination is composed of various specifications of plate components, assembled through various connectors. Hanging cabinets are cabinets that are hung on the wall or on a bracket, which can make more use of space, but the space for human activities under the cabinet must be considered. Cabinet furniture has two types: high and low.

[0003] Chinese patent publication number CN 217408145 U discloses a liftable drawer cabinet, belonging to the technical field of drawer cabinets. In the liftable drawer cabinet, a moving rod is slidably connected inside the hollow sleeve, and the cross bar and the moving rod can form a maximum angle of 90 degrees.

[0004] The above-mentioned patent discloses a liftable drawer cabinet, which is achieved by rotating a hollow sleeve 180 degrees and then fixing the position of the hollow sleeve with a first fastener. At this time, the cross bar is rotated so that the cross bar is located directly below the drawer cabinet body, so that the drawer cabinet can be used as a seat with a backrest, which is more comfortable to use. The size of the backrest can also be adjusted, and the height of the drawer cabinet body can be adjusted after flipping. Although the above-mentioned drawer cabinet can be lifted and lowered and can also serve as a seat, it can only have a single layer, and the storage and load-bearing effects are insufficient, thereby reducing its practicality. For this reason, we provide a drawer cabinet with a liftable structure, which installs a chuck on the inner support frame. When the chuck rotates, it can drive the card-carrying card plate to rotate, thereby indirectly driving the drawer shell and the drawer to move. While being able to adjust any position, it can also have more load-bearing and storage space, effectively compensating for the above-mentioned problems. Summary of the invention
