Layer frame structure with guide rails and drawer device

Abstract

The invention relates to a layer frame structure with guide rails and a drawer device. The layer frame structure with the guide rails comprises a layer frame body, wherein guide rail sliding grooves are formed in two sides of an upper surface of the layer frame body respectively, and the layer frame body and the guide rail sliding grooves are of an integral structure. The drawer device comprises a drawer and at least one layer frame structure with the guide rails, wherein drawer guide rails are arranged on two sides of the drawer, and the drawer is assembled on the guide rail sliding grooves through the drawer guide rails. The layer frame structure achieves portable pushing and pulling by changing assembling modes of the drawer and a layer frame and utilizing the layer frame of a load bearing type guide rail, and compared with the prior art, stress of the guide rails and the layer frame is more even. Stress deformation of the layer frame and the guide rails is improved, and deformation of parts is reduced. The layer frame structure is beneficial to simplifying structures of the parts, reduces cost of the parts, and is suitable for use of assembling drawers, such as a refrigerator, a wine cabinet, a beverage box and a freezer.

Description

[0001] technical field [0002] The invention relates to the technical field of household appliance accessories, and more specifically, to a shelf structure with guide rails and a drawer device. Background technique [0003] The drawers, guide rail frames and layer frames used in the existing refrigeration equipment are separated and are assembled in the form of cantilever beams. For example, Chinese patent ZL201110070024.0 discloses a drawer rail device with a shelf, which uses a suspension to assemble the rail frame 10 below the shelf 20, and the drawer grid 30 is suspended and assembled on the rail frame 10, such as figure 1 , this assembly method needs to increase the force-bearing structure size of the guide rail frame, such as making reinforcing ribs, so as to ensure the rigidity of the assembly. like figure 2 , image 3 It is shown that since the support force F of the shelf 20 and the gravity G of the drawer are not on the same vertical line, the two forces will ...

AI Technical Summary

Problems solved by technology

like figure 2 , image 3 It is shown that since the support force F of the shelf 20 and the gravity G of the drawer are not on the same vertical line, the two forces will generate a deflection moment, which will deform the guide rail frame 10 and cause the guide rail frame 10 to be pulled apart from the upper shelf 20 Trends, which ultimately affect the sliding of drawers
