Description

Technical Field

[0001] The utility model relates to the technical field of household kitchenware, in particular to an adjustable dish rack. Background Art

[0002] Dish racks are used to store clean dishes and facilitate the draining of washed dishes, keeping them clean. In actual use, due to the large number of dishes and their varying sizes, traditional dish racks cannot be adjusted and can only accommodate dishes of a specific size, limiting their practical application.

[0003] To address the aforementioned technical issues, adjustable dish racks have emerged on the market. For example, a dish rack disclosed in Chinese Utility Model Patent Publication No. CN209285288U comprises a set of end panels with handles formed on their upper portions for manual access, a U-shaped base plate connected between the end panels, and a bracket for supporting bowls or plates, which is slidably connected to the lateral slidable steps on the U-shaped base plate. This rack is assembled to facilitate user adjustment and maintenance. However, the bracket is slidably connected to the lateral slidable steps on the U-shaped base plate. When the bracket is assembled, the bracket and the slidable steps are always in close contact. Overcoming the maximum static friction between the bracket and the slidable steps requires considerable effort, making adjustment extremely difficult.

[0004] Another example is a dish rack disclosed in a Chinese utility model patent (publication number: CN217987406U). The rack includes a set of end plates, a support rod connected between the end plates, and multiple support assemblies for supporting bowls or dishes. The support rod is a pipe with notches on opposite sides. The support assembly includes a support plate body, with connecting posts at each end. A locking block is provided at one end of the connecting post, which fits within the notch. The locking block is located within the pipe. The distance between one set of diagonal corners of the locking block is greater than the distance between the other set of diagonal corners, and the inclination direction of the diagonal with the larger distance is opposite to the inclination direction of the support plate body. When locked, the locking block surface of the diagonal portion of the locking block with the larger distance abuts against the wall of the pipe. Locking ribs are provided on the upper and lower walls of the pipe, and the surface of the locking block contacts the surface of the locking ribs. When it is in the unlocked state, the sliding between the support assembly and the support rod is smooth, which makes it convenient for people to adjust the position of the support assembly, overcoming the adjustment difficulty caused by the need to overcome the static friction between the support assembly and the support rod in the prior art.

[0005] However, in the dish rack disclosed in the above-mentioned prior art, when the support assembly needs to be adjusted, the locking hole is driven to rotate in the support rod by rotating the support plate body, and the locking block does not abut against the inner wall of the support rod, so people can slide the support assembly. However, in this process, there is a large gap between the locking block and the locking rib, which makes the support assembly feel loose and moving during sliding, resulting in a poor user experience.

[0006] Therefore it is necessary to improve the existing technology. Utility Model Content
