Embodiment Construction

[0047] figure 1 is a schematic diagram of a drawer assembly according to one embodiment of the present invention; figure 2 yes figure 1 Schematic diagram of the structure of the slide assembly in the drawer assembly shown. Such as Figure 1 to Figure 2 As shown, the embodiment of the present invention provides a drawer assembly 200 for a refrigerating and freezing device (such as a refrigerator). The drawer assembly 200 includes a cylinder 10 with an open front side, a drawer 20 that can be pushed and pulled back and forth into the cylinder 10, and Two slide rail assemblies are respectively arranged at both ends of the cylinder body 10 in the transverse direction (the transverse direction is the left-right direction of the drawer 20 ). Each slide rail assembly includes an inner rail 90 and an outer rail 80 . Wherein, the outer rail 80 is fixed inside the cylinder body 10 so as to extend along the front-rear direction, for example, it is arranged on a lateral side wall of th...

Abstract

The invention relates to a refrigeration and freezing device and a drawer assembly thereof. The drawer assembly comprises a cylinder body of which the front side is open, a drawer which can be inserted into the cylinder body in a front-and-back push-pull manner, and two sliding rail assemblies which are respectively arranged at the two transverse ends of the inner part of the cylinder body; each sliding rail assembly comprises an outer rail which is fixed inside the cylinder body in an extending manner along the front and back directions, an inner rail which is arranged on the outer rail in a front-and-back sliding manner to be supported by the outer rail and is fixed on the drawer, an elastic clamping groove which is arranged at the back end of the outer rail, and a clamping head which is directly or indirectly fixed at the rear end of the inner rail and is inserted into the elastic clamping groove toward the back side in a process of pushing the drawer into the cylinder body, wherein the elastic clamping groove is elastically deformed to clamp the clamping head to ensure that the inner rail is locked on the outer rail and the drawer is locked on the cylinder body. The drawer assembly provided by the invention has the advantages that a locking mechanism between the drawer and the cylinder body has a simple and novel structure and is convenient for users to open or close the drawer.

Description

technical field [0001] The invention relates to a refrigerating device, in particular to a refrigerating and freezing device and a drawer assembly thereof. Background technique [0002] The drawer of the refrigerating and freezing device is generally arranged in a cylindrical body in a push-and-pull manner. With the improvement of food preservation requirements, it is necessary to form a good seal between the front panel of the drawer and the opening of the cylinder after the drawer is fully pushed into the cylinder, that is, it is necessary to make the front panel close to the opening of the cylinder. [0003] For this reason, the existing refrigerating and freezing devices are equipped with complex mechanical or electromagnetic locking mechanisms to lock the drawer and the cylinder body, but the existing locking mechanisms are complex in structure and difficult to manufacture, cumbersome in operation and difficult to control, or high in cost .
