Description

Technical Field

[0001] The utility model relates to the field of refrigerator door shelves, in particular to a multi-layer refrigerator door shelf structure. Background Art

[0002] The refrigerator shelf is the refrigerator door shelf, which mainly includes the door shelf body and the door shelf side panels. The two ends of the door shelf body are connected to the door shelf side panels as a whole, and the door shelf side panels are assembled with the door liner. There is a gap between the door shelf body and the door liner. The cross-sectional shape of the door shelf body is hook-shaped, and the height of the hook part of the hook is about 10mm. This design can ensure that air can flow between the door liner and the door shelf, so that the heat leaking through the door body is directly taken away by the convection part of the air, so that the air temperature of the door shelf part will not be too high.

[0003] After searching, the refrigerator shelf and refrigerator with publication number CN201520145629.5 specifically disclose a shelf body and two parallel arranged clips, wherein the shelf body comprises a grid structure formed by a plurality of rods being hinged; the shelf body is arranged between the two clips and connected with the two clips. The refrigerator shelf provided by the utility model has a plurality of rods constituting the grid structure that are movably connected, and the two clips can support the shelf body, so that the shelf body can be extended and deformed along the length direction perpendicular to the two clips under the action of external force, so that when the above refrigerator shelf is placed in the refrigerator accommodating chamber, the storage area of ​​the same refrigerator shelf can be adjusted at will through the extension and deformation of the shelf body, so as to meet the user's demand for different storage areas of the same refrigerator shelf; and the height restriction of different storage spaces in the vertical direction can be eliminated, so as to meet the user's demand for placing items of different heights, improve the user's convenience of use, and improve the space utilization rate.

[0004] However, the above device still has certain defects. For example, in the refrigerator in the prior art, the bottled item holder inside has a relatively simple function and can generally only be used to place bottled items. Moreover, the bottled item holder is usually fixed in the refrigerator box. When there is no need to place bottled items, it still occupies a large space inside the refrigerator.

[0005] Therefore, it is necessary to invent a multi-layer refrigerator door shelf structure to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a multi-layer refrigerator door shelf structure, which can quickly adjust the relative positions and heights of the upper and lower shelves on the inner side of the side panels through components such as side panels, gears, racks, ratchets, cylinders, torsion bars, etc., so as to make full use of the limited space in the refrigerator and achieve the effect of placing items with gears of different sizes in sections, so as to solve the problem that in the prior art, the bracket is usually fixed in the refrigerator box and still occupies a large space inside the refrigerator when bottled items are not needed.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-layer refrigerator door shelf structure, including a base plate, side plates are bolted on both sides of the front side of the base plate, the middle part of the inner cavity of the side plate is rotatably connected to a gear through a bearing, racks are arranged at the front and back of the inner cavity of the side plate, and the teeth of the rack are meshed with the surface of the gear, a shell is bolted on both sides of the front side of the base plate, a rotating rod is rotatably connected to the inner side of the inner cavity of the shell through a bearing, arc rods are bolted on both sides of the middle part of the rotating rod, a gear rod is bolted on the inner side of the arc rod, a first torsion spring is bolted on the inner side of the inner cavity of the shell, and the other end of the first torsion spring is bolted to both sides of the surface of the rotating rod.

After releasing the torsion bar, the second torsion spring will pull the torsion bar to reset through its own torsional elastic force, and make the pawl contact and mesh with the ratchet again.

[0009] Preferably, the surface of the pawl meshes with the surface of the ratchet wheel, and a twist handle is bolted through the cylinder on the right side of the torsion bar, so that the user can drive the torsion bar to rotate in the cylinder cavity through the twist handle.

[0010] Preferably, a transverse plate is bolted to the inner side of the rack, a slide rail is bolted to the inner side of the transverse plate through the side plate, and a placement rack is slidably connected to the inner side of the slide rail. The transverse plate will synchronously drive the rack to move vertically during the vertical movement. When the placement rack needs to be disassembled and cleaned, it only needs to be pulled out directly from the inner side of the transverse plate through the slide rail.

[0011] Preferably, both the front and rear sides of the inner cavity of the side plate are bolted with limiting grooves, and the inner side of the limiting groove is slidably connected to the toothless portion of the rack, so that the rack is installed in the inner cavity of the side plate through the limiting groove.
