Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a shelf limiting device and refrigeration equipment. Background Technology
[0002] Due to their loading requirements, upright freezers need to have shelves installed inside the cabinet for space division and storage. Conventional support buckles are open supports and do not have a limiting function. During transportation or movement, there is a risk that the shelves may fall or move.
[0003] Currently, some freezers use support clips with limiting devices, but these generally suffer from complex structures leading to high production costs, as well as difficulties in installing and disassembling shelves. For example, CN216797021U discloses a shelf clip and display cabinet. Although the shelf clip has a limiting function, its structure is complex and its production cost is high. In addition, because the shelf clip uses torsion springs to limit the shelf, each shelf generally requires 4-6 shelf clips to provide stable support. The use of torsion springs means that the shelf clips cannot remain open, making the process of installing or disassembling shelves very cumbersome. Utility Model Content
[0004] To address the problems of complex structure and difficult installation and disassembly of shelf limiting devices in existing technologies, the first objective of this utility model is to provide a shelf limiting device including a shelf support. The shelf support includes a snap-fit part and a support part. The snap-fit part is located on one side of the support part. The support part is provided with a limiting groove with a top opening. A first limiting wire and a second limiting wire are respectively arranged opposite to each other on both sides of the limiting groove. The first limiting wire is L-shaped. A locking ring is provided at the corner of the first limiting wire. The second limiting wire is interference-fitted to the locking ring to lock the first limiting wire, so that the first limiting wire and the limiting groove enclose a limiting cavity for restricting the movement of the shelf.
[0005] Specifically, the limiting groove includes a support plate and a first limiting wall and a second limiting wall disposed opposite to each other on both sides of the support plate. The first limiting wire is hinged in the first limiting wall, and the second limiting wire is hinged in the second limiting wall.
[0006] Specifically, the first limiting wall is disposed on the side of the support plate away from the locking part, and the second limiting wall is disposed on the side of the support plate closer to the locking part.
[0007] Specifically, the first limiting wire includes a transverse limiting wire, a longitudinal limiting wire, and a locking ring connecting the transverse limiting wire and the longitudinal limiting wire.
[0008] Specifically, the upper surface of the support plate is provided with a slot, and a rotating stop section is provided on the side of the slot near the first limiting wall.
[0009] Specifically, the latching part is provided with multiple latching blocks.
[0010] Specifically, the latching part includes an upper latching block and a lower latching block. The upper latching block and the lower latching block are arranged in a direction away from the support part. The latching blocks and the support part enclose to form a slot. A guide slope is provided in the lower latching block.
[0011] The second objective of this utility model is to provide a refrigeration device, including a door and a cabinet. The inner wall of the cabinet is provided with a plurality of vertically arranged support bars, and the aforementioned shelf limiting device is installed in the support bars. The shelf limiting device supports the shelf.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This utility model discloses a shelf limiting device. By using a first limiting steel wire and a second limiting steel wire arranged on both sides of the limiting groove, the support plate, the first limiting wall, and the first limiting steel wire are interference-fitted to form a limiting cavity that restricts the movement of the shelf, thus preventing the shelf from moving laterally or longitudinally. The shelf can be locked with only two steel wires, which significantly reduces production costs. When installing and removing the shelf, the first limiting steel wire can be rotated open in sequence before the shelf is placed into the limiting groove or removed from the limiting groove, making the installation and removal of the shelf convenient.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0020] As shown in the figure, this utility model provides a shelf limiting device to solve the problem in the prior art where shelves fall or move due to the lack of limiting mechanisms when refrigeration equipment such as refrigerators and display cabinets are moved. The shelf limiting device includes a shelf support 1, a first limiting wire 2 and a second limiting wire 3 hinged in the shelf support 1, and a limiting cavity that restricts the movement of the shelf 5 by rotating the limiting wires.
[0021] The shelf support 1 is made of ABS material through injection molding and includes a snap-fit part and a support part. Multiple vertically arranged support bars 4 are installed on the inner wall of refrigeration equipment such as refrigerators and display cabinets. Multiple vertically arranged mounting holes 41 are provided in the support bars 4, and the snap-fit part is inserted into the mounting holes 41. Shelf limiting devices are installed in the support bars 4, and multiple shelf limiting devices are set at the same height on the support bars 4. The shelf 5 includes annular side frames and a cross-shaped bearing surface. Items can be placed on the bearing surface. The side frames are installed in the support part. Multiple shelf supports 1 fix the shelf 5 and limit its position to prevent it from falling during transportation.
[0022] The support includes an upright plate and a limiting groove 13 disposed on the top of the upright plate. The limiting groove 13 includes a support plate 14 and a first limiting wall 15 and a second limiting wall 16 disposed opposite to each other on both sides of the support plate 14. The support plate 14, the first limiting wall 15, and the second limiting wall 16 enclose the limiting groove 13 with a top opening, and the limiting groove 13 is supported on the bottom of the side frame. A triangular support frame 18 is provided at the bottom of the support plate 14 to connect the upright plate and the support plate 14, thereby improving the structural strength of the limiting groove 13.
[0023] The first limiting wall 15 is located on the support plate 14 away from the locking part, and the second limiting wall 16 is located on the support plate 14 near the locking part. A first limiting wire 2 is hinged in the first limiting wall 15, and a second limiting wire 3 is hinged in the second limiting wall 16. The first limiting wire 2 and the second limiting wire 3 are integrally formed by bending. The first limiting wire 2 is L-shaped and includes a transverse limiting wire 23, a longitudinal limiting wire 21, and a locking ring 22 connecting the transverse limiting wire 23 and the longitudinal limiting wire 21. The upper surface of the support plate 14 is provided with a slot 17. A stop section 171 is provided on the side of the slot 17 near the first limiting wall 15. When the first limiting wire 2 is rotated to the locking position, the lower end of the transverse limiting wire 23 is located in the slot 17, and the stop section 171 stops the first limiting wire 2. When the shelf limiting device is in the locked state, the lateral limiting wire 23 is perpendicular to the support plate 14, and the longitudinal limiting wire 21 is parallel to the support plate 14, so that the support plate 14, the first limiting wall 15, and the first limiting wire 2 form a limiting cavity that restricts the movement of the shelf 5. The first limiting wire 2, the second limiting wire 3, and the shelf support 1 all have a high elastic modulus and can undergo elastic deformation when subjected to force. The second limiting wire 3 is engaged at the locking ring 22 and is interference-fitted with the first limiting wire 2 to lock the position of the first limiting wire 2, thereby locking the shelf 5 and preventing the shelf 5 from moving laterally or longitudinally.
[0024] The first limiting wire 2 and the second limiting wire 3 are used to form a limiting cavity to lock the shelf 5. It has low production cost and is easy to use. While satisfying the need to support the shelf 5, it can effectively limit the shelf 5 in the horizontal or vertical direction and prevent the shelf 5 from falling.
[0025] The snap-fit part is provided on one side of the upright plate. Multiple vertically arranged snap-fit blocks are provided in the snap-fit part. Preferably, an upper snap-fit block 11 and a lower snap-fit block 12 are provided in the snap-fit part. The upper snap-fit block 11 and the lower snap-fit block 12 are arranged in the direction away from the support part. The snap-fit blocks and the support part enclose to form a slot. A guide slope 121 is provided in the lower snap-fit block 12.
[0026] When locking the limiting groove 13, first rotate the first limiting wire 2 counterclockwise so that its lower end is screwed into the slot 17. Then rotate the second limiting wire 3 clockwise so that it is in an interference fit with the first limiting wire 2, thus securing the first limiting wire 2. When opening the limiting groove 13, forcefully pull the second limiting wire 3 upward from its bottom so that it rotates counterclockwise, releasing the interference fit with the first limiting wire 2. Then rotate the first limiting wire 2 clockwise to open the limiting groove 13.
[0027] When the shelf 5 needs to be installed, rotate the first limiting wire 2 in sequence to open it, place the shelf 5 on the support plate 14, and rotate the first limiting wire 2 and the second limiting wire 3 counterclockwise in sequence to make the second limiting wire 3 and the first limiting wire 2 interference fit, thus locking the shelf 5. When the shelf 5 needs to be removed, turn the second limiting wire 3 in sequence to release the limitation on the shelf 5, pull the shelf 5 upward, and remove the shelf 5.
[0028] When installing the shelf limiting device, first insert the lower locking block 12 into the mounting hole 41 at an angle, and move the shelf support 1 downward until the upper locking block 11 matches the position of the other mounting hole 41. Push the shelf support 1 towards the mounting hole 41 and insert the upper locking block 11 into the mounting hole 41 to complete the installation of the shelf limiting device.
[0029] This utility model also provides a refrigeration device, such as a refrigerator, display cabinet, upright freezer, etc. The refrigeration device includes a door and a cabinet. The inner wall of the cabinet is provided with a plurality of vertically arranged support bars 4. The support bars 4 are provided with a plurality of mounting holes 41 along the vertical direction. Each support bar 4 is provided with one or more shelf limiting devices at a moderate height. The shelf limiting device is provided with a shelf 5.
[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
