Embodiment Construction

[0032] Drawings of embodiments of the present invention will be described in further detail below in conjunction.

[0033] Such as Figure 1 to 3 As shown in a height-adjustable rack comprising a pair of lifting device 2, the plate 1 and the shelving synchronization mechanism, the lifting device 2 two symmetrically installed on both sides of the shelving panel 1, panel 1 and drive down shelving to ensure the synchronous movement of two lifting means, connected by a synchronizing mechanism between the two lifting means 2. The shelving 1 is a rectangular flat plate, the lifting device 2 comprises a rectangular housing 21, the lower rail 22, the cam 24, the upper rail 23 and a return spring 26.

[0034] The inner housing 21 is formed of an elongated slide chamber 21a, and at least the upper end of the sliding chamber port 21a is opened. The lower rail 22 is mounted at the bottom of the slide chamber 21a, the length of the slide rail 22 is smaller than the length of the cavity 21a of t...

Abstract

The invention relates to a height-adjustable shelf, which includes a pair of lifting devices, a shelf and a synchronizing mechanism. The two lifting devices are respectively installed on both sides of the shelf and connected by a synchronizing mechanism. The lifting device includes A housing with a slide chamber and a lower guide rail, a cam, and an upper guide rail installed in the slide chamber; the lower guide rail is configured to slide horizontally along the slide chamber, and the upper guide rail and the inner wall of the slide chamber are provided with a mutually cooperative limiting structure, so that The upper guide rail can only slide up and down in the sliding cavity, and the cam is installed between the upper guide rail and the lower guide rail, and is rollingly matched with the upper guide rail and the lower guide rail; the housing is also provided with a locking structure for locking The lower guide rail; the shelf board is connected with the upper guide rail and keeps moving synchronously with the upper guide rail. The synchronization mechanism connects the lower guide rails of the two lifting devices and keeps the two lower guide rails moving synchronously. The shelf of the invention can be adjusted in height, has simple structure, good bearing effect and low manufacturing cost.

Description

Technical field [0001] The present invention relates to a household appliance, in particular a height-adjustable rack. Background technique [0002] Conventional household refrigerators to increase the internal space utilization, generally a special racks provided inside the refrigerator, refrigerator racks ordinary general manner pluggable card installed in the refrigerator liner, which is a highly slot position decided, not regulation, this will lead to, in some cases, because the shelves reserved for high enough, the article can not be successfully placed in a shelf, remove the shelves if the case will emerge wasted space . Currently, some high-end refrigerator provided in a liftable liner electric rack, such as application number: 201611037914.0 Chinese invention patent, there is disclosed a system for synchronizing a lifting refrigerator rack, comprising: a controller, put rack body and at least two lifting mechanism, the lifting mechanism comprising: a motor, drive screw, g...
