[0033] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] Reference Figure 1 , Figure 2 , Figure 3The lifting shelf proposed in this embodiment of the utility model includes a movable support 100, a drive assembly 200, and a turntable device 300. The movable support 100 is equipped with a shelf assembly. There are two turntable devices 300, which are arranged on the left and right sides of the lifting shelf. The turntable device 300 includes a disc body 310 and a flexible cable 320. The drive assembly 200 is connected to the disc body 310 through a drive shaft 330. The disc body 310 is connected to the first end of the flexible cable 320, and the movable support 100 is connected to the second end of the flexible cable 320. When the drive assembly 200 drives the disc body 310 to rotate in the forward direction, the flexible cable 320 is wound around the mounting part of the disc body 310, and the flexible cable 320 drives the movable bracket 100 to move upward. When the drive assembly 200 drives the disc body 310 to rotate in the reverse direction, the flexible cable 320 is released from the mounting part, and the movable bracket 100 moves downward under its own weight and the weight of the shelf assembly, thereby driving the shelf assembly to move up and down to adjust the position of the shelf assembly in the vertical direction to meet the needs of placing food of different heights.

[0036] In the above embodiments, reference is made to Figure 4 , Figure 5 and Figure 6 The turntable device 300 includes a disc body 310, a first guide structure 400, and a second guide structure 500, both of which are disposed within the disc body 310. The first guide structure 400 includes a first receiving cavity 410 and a first guide groove 420. The first guide groove 420 has a first port and a second port; the first port communicates with the first receiving cavity 410, and the second port communicates with the outside of the disc body 310. The second guide structure 500 includes a second receiving cavity 510 and a second guide groove 520. The second guide groove 520 has a third port and a fourth port; the third port communicates with the second receiving cavity 510, and the fourth port communicates with the outside of the disc body 310. Along the circumferential direction of the disc body 310, the opening direction of the second port of the first guide groove 420 is opposite to the opening direction of the fourth port of the second guide groove 520; that is, the guiding direction of the first guide groove 420 on the flexible cable 320 is opposite to the guiding direction of the second guide groove 520 on the flexible cable.

[0037] The first end of the flexible cable 320 of the turntable device 300 is adapted to be fixed in the first receiving cavity 410 or the second receiving cavity 510, and the second end of the flexible cable 320 is adapted to pass through the corresponding first guide groove 420 or second guide groove 520 and then be wound around the mounting portion of the disc body 310. Specifically, when the turntable device 300 is installed on the left side of the lifting shelf, the first end of the flexible cable 320 is fixed in the first receiving cavity 410, and the second end of the flexible cable 320 passes through the first guide groove 420 and is wound around the mounting portion of the disc body 310 in the reverse direction of the drive assembly; when the turntable device 300 is installed on the right side of the lifting shelf, the first end of the flexible cable 320 is fixed in the second receiving cavity 510, and the second end of the flexible cable 320 passes through the second guide groove 520 and is wound around the mounting portion of the disc body 310 in the forward rotation direction of the drive assembly. The mounting portion includes a groove 340, which is provided on the outer peripheral surface of the disc body 310.

[0038] According to the turntable device 300 of this utility model embodiment, by providing a first guide groove 420 and a second guide groove 520 with opposite guiding directions on the disc body 310, the flexible cable 320 can selectively pass through the first guide groove 420 or the second guide groove 520 corresponding to the installation position of the turntable device 300, so as to change the winding direction of the flexible cable 320. When the turntable device 300 is used on both sides of the lifting shelf, by changing the winding direction of the flexible cable 320, the second ends of the flexible cables 320 on both sides of the lifting shelf extend from the same side of the lifting shelf, so that the flexible cables 320 between the movable brackets 100 on both sides of the lifting shelf and the disc body 310 extend in the vertical direction, avoiding the flexible cable 320 from tilting, so as to avoid the flexible cable 320 from interfering with other components, thereby making the up and down movement of the lifting shelf balanced and stable. Therefore, the turntable device 300 of this utility model has universality and can be used on both sides of the lifting shelf, thereby reducing the types of lifting shelf parts and reducing assembly costs.

[0039] It should be noted that the flexible cable 320 includes, but is not limited to, wire rope, rope, wire or chain, etc. The side wall of the groove 340 is used to limit the flexible cable 320, ensuring that the flexible cable 320 can be wound in the groove 340 when the disc 310 rotates in the forward direction.

[0040] Reference Figure 4 , Figure 6In some embodiments, the first guide groove 420 and the second guide groove 520 are symmetrically arranged, and the first receiving cavity 410 and the second receiving cavity 510 are symmetrically arranged. Specifically, in the embodiment shown in the figure, the first guide groove 420 and the second guide groove 520 are symmetrically arranged vertically relative to the radial direction of the horizontal direction of the disc body 310. Thus, when the turntable device 300 is installed on the left side of the lifting shelf, the disc body 310 can be assembled onto the drive shaft 330 in the normal state. When the turntable device 300 is installed on the right side of the shelf, it is only necessary to rotate the turntable device 300 180° and then assemble the disc body 310 of the turntable device 300 onto the drive shaft 330 to change the winding direction of the flexible cable 320, so that the second ends of the flexible cables 320 on both sides of the lifting shelf extend from the same side of the lifting shelf.

[0041] In some embodiments, the tray 310 is made of plastic, which makes the contact between the turntable device 300 and other mating parts relatively gentle during rotation, especially the contact between the flexible cable 320 and the tray 310. Compared with a metal tray, this reduces friction between the tray 310 and the flexible cable 320, thereby reducing damage to the flexible cable 320 and other mating parts. At the same time, it also reduces the noise of the lifting shelf during operation, which helps to improve the user experience of the storage cabinet using this lifting shelf.

[0042] Reference Figure 4 , Figure 6 In some embodiments, the first guide groove 420 and the second guide groove 520 are both arc-shaped grooves, which can make the bending and rotation of the flexible cable 320 smooth and avoid the phenomenon of wear and breakage of the flexible cable 320 due to stress concentration during the bending and rotation process along the disc 310. This improves the bending and rotation load capacity of the flexible cable 320, extends the bending and rotation life of the flexible cable 320, and improves the reliability of the connection between the flexible cable 320 and the disc 310.

[0043] Reference Figure 3 In some embodiments, the turntable device 300 further includes a drive shaft 330, which is detachably connected to the disc body 310. Detachably connecting the drive shaft 330 to the disc body 310 facilitates the installation and disassembly of the turntable device 300 and allows for convenient maintenance of damaged components. The drive shaft 330 connects the disc body 310 to the drive assembly 200. When the drive assembly 200 drives the disc body 310 to rotate in the forward direction, the flexible cable 320 is wound around the mounting portion of the disc body 310; when the drive assembly 200 drives the disc body 310 to rotate in the reverse direction, the flexible cable 320 is released from the mounting portion.

[0044] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6In some embodiments, the disk body 310 has a first through hole 3122 along its thickness direction, which communicates with the receiving cavity. The first end of the drive shaft 330 is inserted into the first through hole 3122. The disk body 310 is a circular disk body, and the center of the first through hole 3122 coincides with the center of the disk body 310. Furthermore, the first port of the first guide groove 420 communicates with the first receiving cavity 410 through the first through hole 3122, and the third port of the second guide groove 520 communicates with the second receiving cavity 510 through the first through hole 3122.

[0045] Reference Figure 3 In some embodiments, a limiting portion 331 and a locking member 332 are provided at the first end of the drive shaft 330. The limiting portion 331 abuts against the first side of the disc body 310, and the locking member 332 abuts against the second side of the disc body 310. Since the disc body 310 is located between the limiting portion 331 and the locking member 332, the limiting portion 331 and the locking member 332 cooperate to connect the disc body 310 to the first end of the drive shaft 330, preventing the disc body 310 from moving axially along the drive shaft 330. Locking the disc body 310 with the locking member 332 simplifies the installation and removal steps of the disc body 310.

[0046] Reference Figure 3 In some embodiments, a second through hole 334 is provided at the first end of the drive shaft 330, and a locking member 332 is inserted into the second through hole 334. The limiting part 331 includes a limiting step provided at the first end of the drive shaft 330. There are two limiting steps, which are symmetrically arranged. After setting the limiting steps, there is no need to set other limiting parts, which reduces the number of components in the turntable device 300 and simplifies the structure of the turntable device 300.

[0047] It should be noted that at least one plane can be milled on the outer peripheral surface of the first end of the drive shaft 330 using a machining equipment, so that a limiting step is formed on the outer peripheral surface of the first end of the drive shaft 330.

[0048] In some embodiments, the locking member 332 is configured as a latch. After the latch is inserted into the second through hole 334, the clamping part of the latch clamps the first end of the drive shaft 330. This achieves both locking of the disc body 310 and locking of the latch itself, preventing the latch from falling off during rotation of the disc body 310. In addition, the use of the latch facilitates the installation and removal of the disc body 310.

[0049] It should be noted that the locking element 332 can also be a pin, nut, key, etc. When a pin, nut, key, etc. are used as the locking element 332, corresponding through holes, threads, keyways, etc. need to be provided at the corresponding positions of the first through hole 3122 or the drive shaft 330, which will not be described in detail here.

[0050] In some embodiments, the first through hole 3122 is a non-circular hole, and the cross-sectional shape of the first end of the drive shaft 330 is adapted to the shape of the first through hole 3122. By setting the first through hole 3122 as a non-circular hole, the drive shaft 330 can be inserted into the first through hole 3122 to prevent relative rotation between the disk body 310 and the drive shaft 330.

[0051] It is understandable that non-circular holes can be oblong, oval, rectangular, triangular, etc.

[0052] Reference Figure 4 , Figure 5 , Figure 6 In some embodiments, the disc body 310 includes a first disc body 311 and a second disc body 312 that are detachably connected. The second disc body 312 is disposed on one side of the first disc body 311. A first guide structure 400 and a second guide structure 500 are formed on the side of the second disc body 312 facing the first disc body 311. That is, the first receiving cavity 410, the first guide groove 420, the second receiving cavity 510, and the second guide groove 520 are all formed on the side of the second disc body 312 facing the first disc body 311 to facilitate the processing of the disc body 310. Both the first disc body 311 and the second disc body 312 are circular disc bodies 310, and the diameter of the first disc body 311 is equal to the diameter of the second disc body 312. A groove 340 is formed at the connection between the outer peripheral surface of the first disc body 311 and the outer peripheral surface of the second disc body 312. In this embodiment, a protrusion 3123 is provided on the side of the second disc 312 facing the first disc 311. The size of the protrusion 3123 is smaller than the diameter of the second disc 312. When the first disc 311 and the second disc 312 are assembled together, the first disc 311, the second disc 312 and the protrusion 3123 form a groove 340 for the flexible rope 320 to be wound.

[0053] It is understood that in some embodiments, the groove 340 may also be formed on the outer peripheral surface of the second disk 312, which will not be described in detail here.

[0054] Reference Figure 3 In some embodiments, the first disc 311 and the second disc 312 are fixedly connected by screws to facilitate the installation and disassembly of the first disc 311 and the second disc 312. Of course, the first disc 311 and the second disc 312 can also be connected by a snap-fit ​​structure, which is not limited here.

[0055] Reference Figure 5 , Figure 6In some embodiments, the first disc body 311 is provided with an installation port 3111, which is used to communicate with the corresponding first receiving cavity 410 or second receiving cavity 510. The first end of the flexible cable 320 is provided with a positioning head 321, which is used to be engaged in the corresponding receiving cavity. The size of the installation port 3111 is adapted to the size of the positioning head 321 to ensure that the positioning head 321 can pass through the installation port 3111, which facilitates the installation of the turntable device 300.

[0056] Reference Figure 3 The first end of the drive shaft 330 is provided with a slot 333 extending axially. The positioning head 321 is disposed in the receiving cavity. The width of the positioning head 321 is greater than the width of the slot 333. The first end of the flexible cable 320 passes through the slot 333 and connects to the positioning head 321. The slot 333 allows the first end of the flexible cable 320 to pass through and also limits the positioning head 321, thereby connecting the first end of the flexible cable 320 to the first receiving cavity 410 or the second receiving cavity 510. Moreover, by using the slot 333 to limit the positioning head 321, there is no need to set up a separate component to fix the positioning head 321, reducing the types of components. Furthermore, the slot 333 can also play a role in avoiding the flexible cable 320, so that the flexible cable 320 can extend from the first receiving cavity 410 or the second receiving cavity 510 to the corresponding first guide groove 420 and second guide groove 520.

[0057] Reference Figure 3 , Figure 4 A threaded hole 3121 is provided along the thickness direction of the second disc 312. There are four threaded holes 3121 arranged in a square. The first disc 311 is provided with two through holes 3112. The two through holes 3112 penetrate the first disc 311 along the thickness direction of the first disc 311. Furthermore, the two through holes 3112 are opposite to the threaded holes 3121 at the diagonal positions of the second disc 312.

[0058] When the turntable device 300 is installed on the left side of the lifting shelf, screws pass through two through holes 3112 and are threaded into two diagonally opposite threaded holes 3121 of the second disc body 312, thereby fixing the first disc body 311 and the second disc body 312 together and connecting the mounting port 3111 with the first receiving cavity 410. When the turntable device 300 is installed on the right side of the lifting shelf, the second disc body 312 is rotated 180°, and screws pass through two through holes 3112 and are threaded into the other two diagonally opposite threaded holes 3121 of the second disc body 312, thereby fixing the first disc body 311 and the second disc body 312 together and connecting the mounting port 3111 with the second receiving cavity 510. Therefore, the turntable device 300 of this invention can be used not only on the left side of the lifting shelf but also on the right side, possessing versatility, thus reducing the types of components in the lifting shelf and lowering assembly costs.

[0059] It should be noted that the number of through holes 3112 can be the same as the number of threaded holes 3121, as long as the through holes 3112 can be aligned with the corresponding threaded holes 3121 after the second disc body 312 is rotated at a predetermined angle, so that the screw can be threadedly connected to the corresponding threaded hole 3121.

[0060] The lifting shelf proposed in the second aspect of this utility model includes a movable support 100, a drive assembly 200, and a turntable device 300 as described in any of the above, wherein the drive assembly 200 is connected to the disc body 310 via a drive shaft 330, and the movable support 100 is connected to the second end of the flexible cable 320.

[0061] According to the embodiment of the present invention, the lifting shelf has a first guide groove 420 and a second guide groove 520 with opposite guiding directions on the disc body 310. Depending on the installation position of the turntable device 300, the flexible cable 320 can selectively pass through either the first guide groove 420 or the second guide groove 520 to change the winding direction of the flexible cable 320. When the turntable device 300 is used on both sides of the lifting shelf, by changing the winding direction of the flexible cable 320, the second ends of the flexible cables 320 on both sides of the lifting shelf extend from the same side of the lifting shelf. This ensures that the flexible cables 320 between the movable supports 100 on both sides of the lifting shelf and the disc body 310 extend vertically, preventing the flexible cables 320 from tilting and interfering with other components. This results in a balanced and stable vertical movement of the lifting shelf. Therefore, the turntable device 300 of the present invention is versatile and can be used on both sides of the lifting shelf, thereby reducing the types of parts in the lifting shelf and lowering assembly costs.

[0062] The storage cabinet proposed in the third aspect of this utility model includes a cabinet body and the aforementioned lifting shelf, wherein the lifting shelf is disposed inside the cabinet body.

[0063] The storage cabinet of this utility model uses a lifting shelf. By setting a first guide groove 420 and a second guide groove 520 with opposite guiding directions on the tray 310, the flexible cable 320 can selectively pass through the first guide groove 420 or the second guide groove 520 depending on the installation position of the turntable device 300, so as to change the winding direction of the flexible cable 320. When the turntable device 300 is used on both sides of the lifting shelf, by changing the winding direction of the flexible cable 320, the second end of the flexible cable 320 on both sides of the lifting shelf extends from the same side of the lifting shelf, so that the flexible cable 320 between the movable bracket 100 on both sides of the lifting shelf and the tray 310 extends in the vertical direction, avoiding the flexible cable 320 from tilting, thus avoiding interference between the flexible cable 320 and other components, thereby making the up and down movement of the lifting shelf balanced and stable. Therefore, the turntable device 300 of this utility model has versatility and can be used on both sides of the lifting shelf, thereby reducing the types of lifting shelf parts and reducing assembly costs.

[0064] It should be noted that storage cabinets include, but are not limited to, refrigerators, freezers, and cabinets used to place objects.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
