Description

Technical Field

[0001] This utility model relates to the technical field of shelving, and in particular to a combination shelving unit with adjustable shelf height. Background Technology

[0002] Shelves generally refer to racks used for storing goods; they are storage devices for packaged items. Traditional shelves are often multi-tiered, and to maximize storage capacity, they are made very tall. For example, a shelf described in existing technology publication CN210961249U includes fixed plates with threaded holes on both the upper and lower ends. Two sets of fixed plates are provided, with shelves between them. Bolts are located on the right end of the shelves, connecting to the threaded holes. Ventilation slots are provided on the shelves, connecting to a lower air exchange layer. This air exchange layer is filled with irregularly sized particles, and a serpentine tube with air diffusers is located at the bottom. A fixing rod connects to the serpentine tube and is connected via a sealing layer at the bottom. However, because the goods on the shelves vary in height, when adjusting the shelf height is inconvenient, goods are often placed on the shelves without categorization. Large amounts of space remain unused above smaller items, resulting in low shelf utilization and limited storage capacity. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a combination shelf with adjustable shelf height that can be adjusted according to the different heights of goods, making it convenient to classify and place goods and improve space utilization.

[0004] This utility model discloses an adjustable-height combination shelf, comprising a base, multiple counterweight pads, support components, supporting components, and connecting components. Counterweight pads are installed at the four corners of the bottom of the base, and support components are installed at the four corners of the top of the base via connecting components. The supporting components are installed on the support components. The counterweight pads support the bottom of the base, lowering the center of gravity of the equipment and ensuring stability. The support components support the supporting components, enabling the placement and storage of goods. At the same time, the support components can adjust the shelf height according to the different heights of the goods, facilitating the classification and placement of goods and improving space utilization.

[0005] Preferably, the support components include two front columns, two rear columns, two sets of vertical rods, two sets of adjusting layer beams, two sets of locking studs, two sets of fixing plates, and two sets of wing nuts. The two front columns are located on the left and right sides of the front end of the top of the base, and the two rear columns are located on the left and right sides of the rear end of the top of the base. Adjusting grooves are formed inside the front and rear columns, and the vertical rods are installed in the adjusting grooves. The front and rear ends of the adjusting layer beams are slidably installed on the adjusting grooves and the outer walls of the vertical rods. A movable groove communicating with the adjusting groove is formed at the front end of the front column, and the locking studs are located in the movable groove and installed at the front end of the adjusting layer beams. The front end of the front column is positioned relative to the movable groove. The moving slot has multiple sets of locking holes symmetrically arranged. The middle of the fixing plate is inserted into the front end of the locking stud, and the rear end of the fixing plate is provided with a locking pin that matches the locking hole. The wing nut is screwed into the front end of the locking stud. Support is provided by the front and rear columns, which push the adjusting layer beam to slide on the outer wall of the vertical rod and in the adjusting slot. The layer height is adjusted according to the different heights of the goods. The fixing plate is inserted into the locking stud, so that the locking pin enters the locking hole. The wing nut is tightened to fix the locking stud and the fixing plate, thereby limiting and fixing the adjusting layer beam, which facilitates the classification and placement of goods and improves space utilization.
