Description

Technical Field

[0001] The present application relates to the technical field of shelves, and more specifically, to a shelf with good stability. Background Art

[0002] Shelves are metal, wood or plastic rack structures used to store and display goods and items. They are usually used in shopping malls, warehouses, supermarkets, libraries and other places to effectively utilize space and display various goods and items.

[0003] In the related art, it is pointed out that the existing high-level shelves cannot effectively support and prevent tipping in multiple directions at the same time, which greatly affects the normal stability. For example, the patent with the prior art publication number CN219970771U provides a high-level shelf with high stability. The device controls the stabilizing rod and the stabilizing plate to descend through a force ring, and uses the stabilizing plates and reinforced suction cups on the left and right sides to support and stabilize the shelf body in the left and right directions. The threaded rod is controlled to rotate through the operating ring. The rotation of the threaded rod causes the two threaded blocks to pull the support rod to move away from each other, and then the support plate and the stabilizing suction cup are extended in the front and back directions to support and stabilize the shelf body in the front and back directions. Therefore, by supporting and stabilizing the high-level shelf in the front, back, left and right directions, the stability of the high-level shelf is improved to ensure the quality and safety of use.

[0004] Although the above-mentioned existing technical solutions can achieve the effect of improving the stability of the shelf through multi-sided support, they still have the following defects: each support point needs to be adjusted individually, resulting in different support heights at each point, which makes the shelf prone to tilting.

[0005] In view of this, we propose a shelf with good stability. Utility Model Content
