Description

Technical Field

[0001] The utility model relates to the technical field of shelves, in particular to a shelf with adjustable height. Background Art

[0002] In order to improve the utilization rate of the internal space, existing household refrigerators generally have special shelves inside the refrigerator. The shelves of ordinary refrigerators are generally pluggable and mounted in the refrigerator liner. The height is determined by the position of the card slot and cannot be adjusted. This leads to that in some cases, the items cannot be placed on the shelves smoothly due to insufficient reserved height of the shelves. If the shelves are removed, space will be wasted. Some high-end refrigerators are equipped with liftable electric shelves in the liner.

[0003] The Chinese invention patent with application number: 201611037914.0 discloses a lifting synchronization system for a refrigerator shelf, including: a controller, a shelf body and at least two lifting mechanisms, the lifting mechanism includes: a motor, a transmission screw, a guide rod, a connecting piece, and a sliding nut adapted to the transmission screw is also provided on the connecting piece. When the shelf body and the lifting mechanism are assembled, the connecting piece is slidably mounted on the guide rod, and the sliding nut is mounted on the transmission screw. The motor drives the transmission screw to rotate and drive the sliding nut to move up and down, thereby driving the shelf body to move along the guide rod; the controller is configured to control the speed and step number of each motor to gradually become synchronized according to the speed and step number signals of the corresponding motor fed back by each sensor.

[0004] Although the above technical solution solves the problem that the height of the shelf cannot be adjusted, the electric device has a complex structure. In addition, since frost is easy to form inside the refrigerator, the lifting mechanism may malfunction easily. The reliability of use is relatively low, the manufacturing cost is high, and the subsequent maintenance is troublesome. The shelf may slide and fall during the placement process. Therefore, the present application provides a height-adjustable shelf to meet the needs. Utility Model Content

[0007] Optionally, a gripping portion is sleeved and mounted on the shelf body, and a telescopic slot is formed at the bottom end of the gripping portion.

[0008] Optionally, a first spring is embedded in the telescopic slot, and a clamping block is elastically inserted into the telescopic slot through the first spring.

[0009] Optionally, a slot is provided at the top end of the support plate, and a button is protruding from the bottom end of the support plate.

[0010] Optionally, one end of the card block extending out of the telescopic slot is inserted into the card slot, and the top end of the button is slidably inserted into the card slot.

[0011] Optionally, sliding parts embedded in the positioning grooves are fixed at both ends of the support plate, and positioning parts engaged with the positioning grooves are arranged on the sliding parts.

[0012] Optionally, a through groove is formed at the bottom end of the protrusion, and the through groove is connected to the slide groove.

[0013] Optionally, a second spring is embedded in the slide groove, and two ends of the second spring are respectively in contact with the inner wall of the slide groove and the positioning plate.

[0014] Optionally, a lever is embedded in the through slot, and the lever is protruding from the side wall of the raised portion.

[0015] Optionally, the positioning plate is inserted into the slide slot, and one end of the shifting rod extending into the slide slot is fixedly connected to the positioning plate.

[0016] Compared with the prior art, the utility model has at least the following beneficial effects:

[0017] The camming member is a pair of camming members which are arranged on the sides of the support frame, and the camming members are engaged with the camming members, thereby preventing the support frame from falling off the support frame.

[0018] By providing a gripping portion on the shelf body and opening a telescopic slot at the bottom end of the gripping portion, when the shelf body is arranged at the top ends of the two support plates, the first spring in the telescopic slot pushes the card block to fit and be inserted into the card slot opened in the top ends of the support plates, so that the shelf body and the support plates are kept laterally fixed, avoiding the shelf body from sliding and falling off laterally. When the shelf body is disassembled, the button is squeezed to push the card block out of the card slot, and then the shelf body is slid and disassembled between the two support plates, thereby improving the stability of the shelf body when in use.

The plurality of support plates 6 are provided with a plurality of support plates 6 on the bottom of the mounting plate 2 to support the mounting plate 1.

[0034] like Figure 3 , Figure 4 and Figure 5As shown, the shelf body 1 is sleeved with a gripping portion 3, a telescopic slot 10 is provided at the bottom end of the gripping portion 3, a first spring 14 is embedded in the telescopic slot 10, and a card block 13 is elastically inserted into the telescopic slot 10 through the first spring 14, a card slot 11 is provided at the top end of the support plate 6, and a button 12 is protruding from the bottom end of the support plate 6, one end of the card block 13 extending out of the telescopic slot 10 is inserted into the card slot 11, and the top end of the button 12 is slidably inserted into the card slot 11, the sliding grooves 15 at both ends of the support plate 6 are embedded in the positioning slot 7, and the positioning portion 9 on the sliding portion 8 is engaged with the positioning slot 7, and the positioning portion 9 is used to avoid The support plate 6 is prevented from falling off from the mounting plate 2. At the same time, a protrusion 4 is provided on the support plate 6. A second spring 16 and a positioning plate 17 are embedded in the slide groove 15 provided on the protrusion 4. The second spring 16 pushes the positioning plate 17 to fit in and be inserted in the adjustment groove 5 to keep the support plate 6 vertically fixed. When the height of the support plate 6 and the shelf body 1 is adjusted, the positioning plate 17 is driven to slide in the slide groove 15 by the lever 18, and is moved out of the adjustment groove 5 during the sliding process, so that the support plate 6 can slide and adjust on the side wall of the mounting plate 2, and the lever 18 is released after adjustment to allow the positioning plate 17 to be inserted into the adjustment groove 5 at different positions.

[0035] The two ends of the support plate 6 are fixed with a sliding part 8 embedded in the positioning groove 7, and the sliding part 8 is provided with a positioning part 9 engaged with the positioning groove 7. The bottom end of the protrusion 4 is provided with a through groove 19, and the through groove 19 is connected to the slide groove 15. A second spring 16 is embedded in the slide groove 15, and the two ends of the second spring 16 are respectively abutted against the inner wall of the slide groove 15 and the positioning plate 17. A lever 18 is embedded in the through groove 19, and the lever 18 is protruding on the side wall of the protrusion 4. The positioning plate 17 is fitted and inserted in the slide groove 15, and one end of the lever 18 extends into the slide groove 15 and is fixedly connected with the positioning plate 17. When the shelf body 1 is arranged at the top ends of the two support plates 6, the first spring 14 in the telescopic groove 10 pushes the card block 13 to fit and insert into the card groove 11 opened at the top end of the support plate 6, so that the shelf body 1 and the support plate 6 are kept horizontally fixed, avoiding the shelf body 1 from sliding and falling off horizontally.
