[0016] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] See also Figure 1-3As shown, the utility model proposes a refrigerator drawer installation device, which includes a box body 11, a guide rail 21, and an outer cover 31. The box body 11 is slidably connected to the guide rail 21. The guide rail 21 is arranged on the inner wall of the refrigerator and is slidably connected to both sides of the box body 11.

[0018] A first roller 41 and a slide rail 43 are arranged on the outer wall of the side of the box body 11, wherein the first roller 41 is rotatably connected to the outer wall of the box body 11, the second roller 42 is rotatably connected to the outer cover 31, the outer cover 31 is connected to the guide rail 21 and is arranged on the guide rail 21, the slide rail 43 is extended along the depth direction of the box body 11, the second roller 42 is arranged on the front side of the box body 11, the first roller 41 is located on the rear side of the box body 11 and at the end of the slide rail 43, and the slide rail 43 is located between the top wall of the guide rail 21 and the bottom wall of the guide rail 21.

[0019] The outer wall of the first roller 41 abuts against the bottom wall of the guide rail 21, and the outer wall of the second roller 42 abuts against the bottom wall of the slide rail 43. The outer diameter of the first roller 41 is larger than the outer diameter of the second roller 42. The first roller 41 guides the rear end or end of the box body 11 when it moves along the guide rail 21, and the second roller 42 supports the front end of the slide rail 43 provided on the box body 11.

[0020] The angle between the bottom wall of the guide rail 21 close to the second roller 42 and the bottom wall of the guide rail 21 close to the first roller 41 is the second angle A1, and the angle between the bottom wall of the guide rail 21 close to the first roller 41 and the bottom wall of the guide rail 21 close to the second roller 42 is the second angle A2. Both the second angle A2 and the second angle A1 are obtuse angles and the second angle A2 is greater than the second angle A1. The difference between the second angle A2 and the second angle A1 ranges from 10° to 30°.

[0021] As a result, when the box body 11 is pulled outward, it is first guided by the first roller 41 through the inclined surface of the second angle A1 on the guide rail 21, and then guided by the second roller 42 through the inclined surface of the second angle A2 on the slide rail 43 to achieve lifting in the height direction at the front and rear ends during the pulling-out process. As a result, when the box body 11 carries a large number of items, the inconvenience of pulling out due to its heavy weight can be avoided, thereby facilitating user operation. The inclined surface guidance of the second angle A1 and the second angle A2 can more efficiently realize the drawer pulling operation, so that the box body 11 is offset upward in the height direction and the pressure on the lower part is reduced. The rear end of the box body 11 can be guided along a lower slope with a larger second angle A1 and offset in the height direction, and the front end of the box body 11 can be guided along a higher slope with a smaller second angle A2, thereby achieving smooth movement and offset in the height direction, facilitating user operation experience.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
