The height of the front wall 22 is less than the height of the rear wall 24. The front wall 22, the two side walls 23 and the rear wall 24 are used for isolating the storage space of the storage box 2 from the compartment, so that the user can place the articles in the storage box 2 and outside the storage box 2 in order. The front wall 22 and the rear wall 24 also serve to block the articles in the storage case 2. When the storage box 2 is in a forward tilting state with a low front and a high rear, the articles in the storage box 2 can slide to the front end of the storage box 2 and touch the inner side of the front wall 22, and cannot fall out. When the storage box 2 is in a backward inclined state with the front high and the rear low, the articles in the storage box 2 can slide to the rear end of the storage box 2 and touch the inner side of the rear wall 24, and cannot fall out. The two side walls 23 may be arranged low at the front and high at the rear, or may be arranged horizontally, or may have other shapes. When the two side walls 23 are arranged to be low at the front and high at the rear, it is convenient for the user to see the articles in the storage box 2 from the front or from the side. Of course, the storage box 2 can also be made of transparent materials, so that a user can intuitively see articles in the storage box 2 on one hand, and illumination light rays in a refrigerator compartment can not be blocked on the other hand, and a darker blind area is formed in the storage box 2.

In some embodiments of the rack of the present utility model, the rear and front links 31, 32 are hinged to the rack plate 1 by means of damped hinges. The raised state of the storage case 2 in the present utility model does not mean that the front link 32 or the rear link 31 is in a vertical state. As long as the storage box 2 is not placed on the upper surface of the deck 1, it is called a raised state, that is, when the front link 32 or the rear link 31 is in an inclined state, also a raised state. In this embodiment, by providing the damping hinge, the damping hinge is formed between the rear link 31 and/or the front link 32 and the rack 1, so that the rear link 31 and/or the front link 32 can always maintain a certain damping during rotation, and the storage box 2 can stably maintain its state when the rear link 31 and/or the front link 32 are at any angle. Therefore, the user can rotate the storage box 2 to the required height according to the requirements of the heights of the articles, articles in the refrigerator compartments can be placed neatly and orderly, the space of the refrigerator compartments is fully utilized, and the space utilization efficiency is improved.

In some embodiments of the rack of the present utility model, the front link 32 forms a hinge with the rack plate 1 by a damped hinge. In this embodiment, by providing the damping hinge, the damping hinge is formed between the front link 32 and the rack 1, so that the front link 32 can always maintain a certain damping during rotation, and the storage box 2 can stably maintain its state when the front link 32 is at any angle. Compared with the damping hinge arranged between the front connecting rod 32 and the article placing plate 1 and between the rear connecting rod 31 and the article placing plate 1, the damping hinge arranged between the front connecting rod 32 and the article placing plate 1 can meet the requirements because the weight of articles in the storage box 2 is not too heavy, so that the storage box 2 can stably maintain the state of the articles, and the production cost can be reduced.

In some embodiments of the rack of the present utility model, the front link 32 is hinged to the rack plate 1 by a screw 4. The screw 4 acts as a rotation shaft, and the lower support 3122 is provided with a through hole. The magnitude of the damping force can be adjusted by tightening or loosening the screw 4. Compared with the damping hinge formed between the front connecting rod 32 and the object placing plate 1 and between the rear connecting rod 31 and the object placing plate 1 through the screw 4, the damping hinge is arranged between the front connecting rod 32 and the object placing plate 1 only because the weight of objects in the storage box 2 cannot be too heavy, so that the requirements can be met, the storage box 2 can stably maintain the state of the storage box, and the production cost can be reduced.

In some embodiments of the rack of the present utility model, the rack further comprises an electric device configured to drive the upper link 311 to slide along the lower link 312. The electric device can be an electric push rod, a motor and the like, can liberate the hands of a user, automatically adjust the lifting support device 3 at a preset height, and can directly take and put articles in the storage box 2.

In some embodiments of the rack of the present utility model, the motorized device is configured to simultaneously drive the front 32 and rear 31 links in a lateral direction, driving the storage case 2 between a lowered state and a raised state. The user's hands can be liberated, the efficiency of accessing article is improved.

In some embodiments of the rack of the present utility model, the motorized device is configured to drive the front 32 or rear 31 links in a lateral direction, driving the storage case 2 between a lowered state and a raised state.

In some embodiments of the refrigerator of the present utility model, the refrigerator includes a compartment, and a rack for the refrigerator, the rack being disposed in the compartment.

In some embodiments of the refrigerator of the present utility model, the plurality of racks are provided in the compartment at intervals up and down.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been shown and described herein in detail, many other variations or modifications of the utility model consistent with the principles of the utility model may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the utility model. Accordingly, the scope of the present utility model should be understood and deemed to cover all such other variations or modifications.
