Description

Adjusting device and drawer cabinet

Technical Field

The utility model relates to a drawer technical field especially relates to an adjusting device and drawer cabinet.

Background

In the drawer installation of the cabinet body, because there is machining error between the spare part, appear "the upper end pastes tightly easily between the drawer frame edge of panel in drawer the place ahead and the cabinet body, and the lower extreme has gap" or "the lower extreme pastes tightly, and there is the gap" scheduling problem in the upper end, for making the gap between drawer frame edge and the panel even, among the prior art, often set up adjusting device on the drawer in order to adjust.

The existing adjusting device mainly adopts two modes of panel adjustment and side wall adjustment:

the panel adjustment means that an adjusting device capable of rotating in the vertical direction is arranged between the panel and the side wall, the adjusting device drives the panel to rotate relative to the side wall to achieve adjustment, and the adjusting mode has the defects that a large gap exists between the panel and the side wall due to the inclination of the panel, and the panel is pulled obliquely according to the requirement of opening a drawer in the long-term daily use process, so that the adjusting device arranged between the panel and the side wall is prone to failure.

The side wall adjustment means that an adjusting device is arranged behind the side wall of the drawer, and the adjusting device drives the rear part of the side wall to lift, so that the whole drawer is in an inclined state relative to the sliding rail assembly, the adjustment of a gap between the edge of the drawer frame and a panel is realized, the problem of the panel adjusting mode can be effectively solved by the side wall adjusting mode, and the side wall adjusting mode is more widely applied to production.
