[0051] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0052] For example, the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like as used herein to describe a spatial relationship between one element or feature to another element or feature are for convenience only, and are not intended to limit the scope of the application to only such relative positions. The terms can encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures.

[0053] For example, if the device in the figures is turned over, elements described as on the "lower" side of other elements or features would then be oriented on the "upper" sides of the other elements or features. The exemplary term "lower" can, therefore, encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0054] In the description of the present application, it is necessary to explain that, unless explicitly defined and limited otherwise, the terms "mounting", "connecting", "connection" should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be mechanically connected, or electrically connected; can be directly connected, or indirectly connected through an intermediate medium, or can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0055] And it should be understood that although the terms first, second, etc. can be used herein to describe various elements or structures, these described objects should not be limited by these terms. These terms are only used to distinguish one described object from another. For example, a first fixed column can be called a second fixed column, and similarly a second fixed column can also be called a first fixed column, which does not depart from the scope of protection of the present application.

[0056] The embodiment of the present application provides a shelf assembly 100, which can be used in a refrigeration device, the refrigeration device provided with the shelf assembly 100 comprises a box body provided with a refrigeration compartment and the shelf assembly 100 arranged in the refrigeration compartment, and thus the present application further provides a refrigeration device provided with the aforementioned shelf assembly 100.

[0057] As shown in FIGS. 1-3, the aforementioned shelf assembly 100 comprises a shelf plate 1, a support mechanism 2, and a connecting piece 3 connecting the shelf plate 1 and the support mechanism 2, the support mechanism 2 being provided with a first fixing structure 201 and a second fixing structure 202 at intervals along the length direction; the connecting piece 3 is connected with the shelf plate 1, and the connecting piece 3 is provided with a first hanging groove 31 and a matching part 301 at intervals near one end of the support mechanism 2, the first hanging groove 31 is hung on the support mechanism 2 through the first fixing structure 201, and the matching part 301 cooperates with the second fixing structure 202; the locking mechanism 4 comprises a locking state of locking the matching part 301 and the second fixing structure 202, and an unlocking state of allowing the matching part 301 and the second fixing structure 202 to be separated.

[0058] In the present application, the connection between the connecting piece 3 and the support mechanism 2 is not achieved by hanging through two downward hanging grooves, but only one first hanging groove 31 is provided to be hung on the support mechanism 2, and the matching part 301 of the connecting piece 3 cooperates with the second fixing structure 202 of the support mechanism 2 to achieve the connection between the connecting piece 3 and the support mechanism 2. In this way, when the shelf plate 1 is installed, only the first hanging groove 31 needs to be hung on the support mechanism 2 through the first fixing structure 201, and then the shelf plate 1 is rotated to make the matching part 301 cooperate with the second fixing structure 202, without the need to lift the whole shelf plate 1 and then put it down, and there is no limitation on the structure of the support mechanism 2 above the positions of the first fixing structure 201 and the second fixing structure 202.

[0059] Furthermore, when the shelf assembly 100 is adjusted in height by the gear 52 and the rack 51 as described below, and the gear 52 is provided with a damping member 53, the installation method in the present application will not be affected by the damping member 53 to affect the installation speed of workers due to the need to lift and then put down the shelf plate 1. In addition, the matching part 301 and the second fixing structure 202 are locked or unlocked by the locking mechanism 4, so that the locking mechanism 4 is unlocked during the installation or disassembly of the shelf plate 1, and is locked and fixed after installation is completed.

[0060] It should be noted that the shelf assembly 100 is described in the normal use state in this article, i.e., the shelf plate 1 is arranged substantially horizontally, the first direction in the following is the vertical direction, up and down are the commonly used orientation words in the vertical direction, and the drawings in the present application show that the support mechanism 2 is located at the rear side of the shelf plate 1, so that the side close to the user when the user faces the shelf assembly 100 is the front side.

[0061] In some embodiments, the support mechanism 2 comprises a support 21 and an adapter 22 connected with the support 21, the first and second fixing structures 201 and 202 are respectively a first fixing column 221 and a second fixing column 222 arranged on the adapter 22; the cooperation part 301 is a second hanging groove 32 with an opening facing the support 21, and the first and second hanging grooves 31 and 32 are respectively hung on the first and second fixing columns 221 and 222. The first fixing column 221 serves as the first fixing structure 201 for hanging the first hanging groove 31, and the first hanging groove 31 can be downwardly opened as shown in FIG. 2, or upwardly opened. The second fixing column 222 can provide support for the connecting piece 3 in the vertical direction, and also bear the pressure from the deflection of the front end of the shelf 1 downward in the horizontal direction.

[0062] In addition to the cooperation mode of the hanging groove and the fixing column as described above, in other embodiments, the connection mode of the connecting piece 3 and the support mechanism 2 further comprises:

[0063] The first and second fixing structures 201 and 202 are respectively a first and a second clearance hole 213 and 214 arranged on the support 21, and the cooperation part 301 is a limiting piece arranged in an extending manner towards the support 21 (blocked by the locking mechanism 4 in FIG. 4), the first hanging groove 31 is hung on the support 21 by passing through the first clearance hole 213, and the limiting piece passes through the second clearance hole 214.

[0064] The first hanging groove 31 is also connected with the support 21 in a hanging manner, which is different from the above-mentioned mode, that is, the first hanging groove 31 passes through the first clearance hole 213 and is hung at a position below the first clearance hole 213 on the support 21. The limiting piece passing through the second clearance hole 214 can avoid the left and right deflection of the connecting piece 3 and cannot abut against the support 21. Of course, the first hanging groove 31 can also be hung at a position above the first clearance hole 213 on the support 21, that is, the first hanging groove 31 is upwardly opened.

[0065] In FIGS. 2 and 4, the first hanging groove 31 and the cooperation part 301 are in a position relationship that the first hanging groove 31 is above and the cooperation part 301 is below, but they can also be arranged in a position relationship that the first hanging groove 31 is below and the cooperation part 301 is above, and the present application does not limit the position relationship of the first hanging groove 31 and the cooperation part 301.

[0066] In some embodiments, the locking mechanism 4 comprises a center shaft 41, a locking piece 42 and a first elastic piece 40, the center shaft 41 is connected with the connecting piece 3, the locking piece 42 rotates around the center shaft 41, the first elastic piece 40 deforms with the rotation of the locking piece 42, and the locking mechanism 4 is in a locked state when the first elastic piece 40 is not under stress.

[0067] The center shaft 41 is connected with the connecting piece 3, which can be provided with a hole or a slot for the center shaft 41 to pass through, or the center shaft 41 can be integrally provided with the connecting piece 3. The locking piece 42 is sleeved on the center shaft 41 to rotate around the center shaft 41. When the locking piece 42 rotates, the first elastic piece 40 is deformed. When the first elastic piece 40 is not stressed, the locking mechanism 4 is in a locked state. For example, as shown in FIG. 3, taking the first connection mode of the connecting piece 3 and the support mechanism 2 as an example, at this time, the locking piece 42 blocks the second fixed column 222 on the side close to the support piece 21. This state is when the shelf 1 is installed and normally used. If the locking piece 42 rotates to make the second fixed column 222 not blocked on the side close to the support piece 21, at this time, the first elastic piece 40 is deformed under stress, and the locking mechanism 4 is in an unlocked state. At this time, the locking piece 42 is provided for the second hanging groove 32 to be hung on the second fixed column 222, or the locking piece 42 is provided for the second hanging groove 32 to be separated from the second fixed column 222.

[0068] For example, as shown in FIG. 4, taking the second connection mode of the connecting piece 3 and the support mechanism 2 as an example, when the locking mechanism 4 is in a locked state, the locking piece 42 passes through the second gap hole 214 and abuts against the side of the support piece 21 away from the connecting piece 3. If the locking piece 42 rotates to make the locking piece 42 deviate from the support piece 21, at this time, the first elastic piece 40 is deformed under stress, and the locking mechanism 4 is in an unlocked state.

[0069] Hereinafter, the related content of the locking mechanism 4 is taken as an example of the first connection mode of the connecting piece 3 and the support mechanism 2.

[0070] In some embodiments, the shelf assembly 100 provided by the present application further comprises a first side decorative shell 8, which is wrapped on one side edge of the connecting piece 3. One end of the first elastic piece 40 is fixed relative to the first side decorative shell 8, and the other end is fixed to the locking piece 42 and rotates with the rotation of the locking piece 42.

[0071] The first side decorative shell 8 is wrapped on one side edge of the connecting piece 3 to wrap all the components connected to the connecting piece 3 to ensure the appearance, that is, the first side decorative shell 8 is relatively stationary relative to the connecting piece 3. One end of the first elastic piece 40 is fixed relative to the first side decorative shell 8, and the other end rotates with the rotation of the locking piece 42. Thus, the first elastic piece 40 can be compressed or stretched under stress during the rotation of the locking piece 42, so as to switch the locking mechanism 4 between the locked state and the unlocked state.

[0072] The shelf assembly 100 provided by the present application further comprises a second side decorative shell 9 wrapped on the other side edge of the connecting piece 3. The first side decorative shell 8 and the second side decorative shell 9 form a cavity therebetween to wrap the connecting piece 3 and the components on both sides of the connecting piece 3, so as to ensure the appearance of the shelf assembly 100.

[0073] In some embodiments, as shown in FIG. 3, 5, the first elastic member 40 is a torsion spring 43, which includes a torsion spring body 431, a first end 432 and a second end 433 connected to two ends of the torsion spring body 431; the locking member 42 is protruded towards one side of the first side decorative shell 8 to form a first circular ring part 4221 with a notch, and is further provided with a fixing groove 4222 in communication with the inner circle of the first circular ring part 4221, the torsion spring body 431 is arranged in the first circular ring part 4221, the first end 432 extends out of the notch, and the second end 433 is arranged in the fixing groove 4222; the first side decorative shell 8 is provided with a second circular ring part 81 corresponding to the first circular ring part 4221, the second circular ring part 81 is sleeved outside the first circular ring part 4221 and is provided with a notch at the same position, and the first end 432 further extends out of the notch of the second circular ring part 81.

[0074] It should be noted here that the second circular ring part 81 in FIG. 5 is partially incomplete at the position close to the gear 52 (upper position) to give way to the gear 52 in the following description, but this does not affect the function of the second circular ring part 81. If the gear 52 is far enough from the second circular ring part 81, the second circular ring part 81 is only provided with a unique notch at the notch formed by the first circular ring part 4221.

[0075] The first circular ring part 4221 formed by the locking member 42 can be sleeved on the central shaft 41 and rotate about the central shaft 41, the torsion spring body 431 of the torsion spring 43 is also sleeved on the central shaft 41, and the second circular ring part 81 is sleeved on the first circular ring part 4221, i.e., the torsion spring body 431, the first circular ring part 4221 and the second circular ring part 81 are sequentially sleeved outside the central shaft 41. The first circular ring part 4221 and the second circular ring part 81 are provided with notches at the same position, so that the first end 432 of the torsion spring 43 extends out of the notches of the first circular ring part 4221 and the second circular ring part 81, and the second end 433 of the torsion spring 43 is arranged in the fixing groove 4222 of the locking member 42.

[0076] When the locking mechanism 4 switches between the locked state and the unlocked state, the locking member 42 drives the torsion spring 43 to rotate in the second circular ring part 81, so that the first end 432 of the torsion spring 43 can only move within a small range of the width of the notch of the second circular ring part 81 since it extends out of the notch of the second circular ring part 81, and the second end 433 of the torsion spring 43 rotates with the locking member 42 to compress or stretch the torsion spring body 431, so that the torsion spring body 431 is stressed. Of course, the width of the notch of the second circular ring part 81 is sufficient for the first end 432 of the torsion spring 43 to extend out, and can be slightly larger than the first end 432 of the torsion spring 43, which is not limited here.

[0077] In some embodiments, the locking member 42 comprises a first locking member 421 and a second locking member 422, the first locking member 421 is provided with a locking hook 4211, and the second locking member 422 is provided with a knob 4223, and the second locking member 422 drives the first locking member 421 to rotate.

[0078] The locking hook 4211 is used to shield the second fixing column 222 near the support member 21, and the user rotates the knob 4223 to drive the second locking member 422 to rotate. When installing the shelf 1, first, the first hanging groove 31 is hung on the first fixing column 221, and then the shelf 1 is rotated, as shown in FIG. 3, after the locking hook 4211 hits the second fixing column 222, it is forced to rotate downward, so that the second hanging groove 32 can be hung on the second fixing column 222, when it is needed to remove the shelf 1, the knob 4223 is rotated counterclockwise as shown in FIG. 3, the second locking member 422 drives the first locking member 421 to rotate, the locking hook 4211 is allowed to make room, so that the second hanging groove 32 can be separated from the second fixing column 222, thereby removing the shelf 1.

[0079] In some embodiments, as shown in FIG. 6, the second locking member 422 is buckled to the first locking member 421 and drives the first locking member 421 to rotate synchronously, the first circular ring part 4221 and the fixing groove 4222 are arranged on the second locking member 422. The first locking member 421 is provided with a sleeve hole 4212 which is sleeved on the center shaft 41, and the second locking member 422 is sleeved on the center shaft 41 through the first circular ring part 4221. The side part of the second locking member 422 extends to the side of the first locking member 421 to form a buckling part 4224, the shape of the buckling part 4224 is matched with the first locking member 421, and the buckling part 4224 abuts against the side edge of the first locking member 421.

[0080] When the locking mechanism 4 is installed, first, the center shaft 41 is fixed to the connecting member 3, the first locking member 421 is sleeved on the center shaft 41, then the second end 433 is fixed to the torsion spring 43 and the second locking member 422 which are sleeved on the center shaft 41, and it is ensured that the first end 432 extends from the first circular ring part 4221. When the second locking member 422 is installed, the buckling part 4224 needs to be aligned with the first locking member 421.

[0081] In some embodiments, as shown in FIGS. 1 and 2, the support member 21 is provided with a sliding groove 211 extending in the first direction and a pulley 212 arranged in the sliding groove 211, and the adapter 22 is provided with a connecting hole 223, the pulley 212 is connected with the adapter 22 through the connecting hole 223, and the pulley 212 indicated by the reference numeral 212 in FIG. 1 is only a part of the pulley, and the remaining part is shielded by the adapter 22.

[0082] The first direction is vertical direction due to the description of the shelf assembly 100 in normal use state. The shelf assembly 100 further comprises an adjusting mechanism, the adjusting mechanism comprises a rack 51, a gear 52 and a damping member 53, the rack 51 is fixed to the support 21 and parallel to the sliding groove 211, the gear 52 is rotationally connected with the connecting piece 3, the damping member 53 provides damping force for the gear 52, the gear 52 is engaged with the rack 51 so as to adjust the height of the shelf plate 1, and the damping member 53 provides damping force when the shelf plate 1 moves downward to prevent the shelf plate 1 from rapidly descending under the action of gravity.

[0083] Due to the mounting mode of the shelf plate 1 in the present application is to hang the first hanging groove 31 on the first fixed column 221, and then rotate the shelf plate 1 to hang the second hanging groove 32 on the second fixed column 222, after the first hanging groove 31 is hung on the first fixed column 221, the gear 52 and the rack 51 are not engaged, and are engaged with each other only when the shelf plate 1 is rotated, at this time, the shelf plate 1 does not need to be lifted and then lowered, therefore, the damping member 53 has no effect on the installation of the shelf plate 1 during the installation of the shelf plate 1, and does not affect the time of workers installing the shelf plate 1.

[0084] The damping member 53 comprises a damping wheel 531 and a damper 532 providing damping force for the damping wheel 531, the damping wheel 531 is detachably connected with the damper 532, and the damping wheel 531 is engaged with the gear 52; wherein the pitch circle radius r1 and the number of teeth z1 of the damping wheel 531 satisfy the following formula:

[0085] ,

[0086] Wherein, k, b are constants in the damping and rotational speed relationship formula of the damper 532, g is the acceleration of gravity, m is the preset load bearing capacity of the shelf plate 1, r2 is the pitch circle radius of the gear 52, z2 is the number of teeth of the gear 52, and v is the preset descending speed of the shelf plate 1.

[0087] Since the rotational speed ω1 and the number of teeth z1 of the damping wheel 531 and the rotational speed ω2 and the number of teeth z2 of the gear 52 satisfy: ω1×z1=ω2×z2 (Formula 1), then ω1 is:

[0088] .

[0089] The descending speed v of the shelf plate 1 is the linear speed of the gear 52, and the rotational speed ω2 of the gear 52 is:

[0090] ;

[0091] r2 is the pitch circle radius of the gear 52, and ω1 is:

[0092] (Formula 2).

[0093] The relationship between the damping T of the damper 532 and the rotational speed ω satisfies a linear function T=kω+b, the rotational speed ω of the damper 532 is the rotational speed ω1 of the damping wheel 531, the damping force F output by the damping wheel 531 is T / r1, and r1 is the pitch circle radius of the damping wheel 531. Then the descending acceleration a of the shelf 1 is:

[0094] (Formula 3),

[0095] m is the load of the shelf 1, specifically the total weight of the shelf 1 itself and the objects placed thereon; if the descending speed of the shelf 1 is to be kept constant, the descending acceleration a of the shelf 1 is 0, and then

[0096] (Formula 4).

[0097] Since the gear 52 and the rack 51 are engaged and cannot be replaced, only the pitch circle radius r1 and the number of teeth z1 of the damping wheel 531 can be changed. And according to Formula 4, if the load of the shelf 1 increases, the pitch circle radius r1 and / or the number of teeth z1 of the damping wheel 531 need to be reduced.

[0098] In some embodiments, the connecting piece 3 is provided with a through hole 35; as shown in FIG. 8, the damping wheel 531 is provided with a non-circular hole 5311, the damper 532 is provided with a non-circular cylinder 5321 matched with the non-circular hole 5311, the damper 532 is fixed to the connecting piece 3 and passes through the through hole 35, the non-circular cylinder 5321 passes through the non-circular hole 5311, and the connection between the damping wheel 531 and the damper 532 is achieved. Thus, the damping wheel 531 can be detached from the non-circular cylinder 5321 according to the load of the shelf 1 for replacement.

[0099] In some embodiments, the shelf assembly 100 further comprises a synchronous mechanism and a limiting mechanism, the synchronous mechanism comprises a synchronous rod 61 and synchronous wheels 62 located at both ends of the synchronous rod 61, the synchronous wheels 62 are engaged with the gear wheels 52; the limiting mechanism comprises a ratchet wheel 71 and a movable rod 72, the ratchet wheel 71 is coaxially arranged with the synchronous wheels 62. As shown in FIG. 7, 9, the gear wheels 52, the synchronous wheels 62 and the damping wheels 531 are arranged on the outer side of the connecting piece 3, i.e. the side away from the shelf plate 1, the ratchet wheel 71 is arranged on the inner side of the connecting piece 3, the both ends of the synchronous rod 61 are non-circular, the first non-circular groove 711 corresponding to the non-circular structure of the both ends of the synchronous rod 61 is arranged on the side of the ratchet wheel 71 close to the synchronous rod 61, the non-circular protrusion 712 is arranged on the side of the ratchet wheel 71 close to the synchronous wheel 62, the second non-circular groove 621 corresponding to the non-circular protrusion 712 is arranged on the side of the synchronous wheel 62 close to the ratchet wheel 71, the non-circular structure of the end of the synchronous rod 61 is inserted into the first non-circular groove 711 of the ratchet wheel 71, the non-circular protrusion 712 is arranged in the second non-circular groove 621 through the connecting piece 3, so that the synchronous wheels 62 at both ends of the synchronous rod 61 are engaged with the gear wheels 52 on both sides of the shelf plate 1 respectively, and the adjustment synchronization on both sides is better when the shelf plate 1 is moved up or down.

[0100] In some embodiments, the movable rod 72 comprises a locking position matched with the ratchet wheel 71 to limit the rotation of the ratchet wheel 71 when the shelf plate 1 is moved downward, and a release position separated from the ratchet wheel 71. As shown in FIG. 7, 10, the adjusting mechanism is arranged on the rear side close to the shelf plate 1, the movable rod 72 can be moved in the front-rear direction and is provided with a convex ring 721; the limiting mechanism is further provided with a spring and a first limiting block 723 connected with the connecting piece 3, the first limiting block 723 is provided with a first limiting hole 7231 matched with the cross section of the movable rod 72, the movable rod 72 passes through the first limiting hole 7231, the front end of the spring abuts against the first limiting block 723, and the rear end abuts against the convex ring 721.

[0101] The limiting piece is provided with two and limits the movable rod 72 to be moved only in the front-rear direction through the first limiting hole 7231, the spring 722 is preferably a spring, is sleeved on the movable rod 72 and is matched with the limiting piece at the front end. After the movable rod 72 is forced to move forward, the spring 722 is compressed, and after the movable rod 72 loses the force, the restoring force of the spring 722 makes the movable rod 72 move backward to match the ratchet wheel 71 to lock the ratchet wheel 71, and then lock the relative movement of the gear wheel 52 and the gear rack 51, so as to lock the position of the shelf plate 1.

[0102] When the movable rod 72 is in the locking position, if the ratchet wheel 71 rotates clockwise in FIG. 7 (corresponding to the upward movement of the shelf plate 1), the ratchet wheel 71 pushes the movable rod 72 forward, and it is to be noted that the movable rod 72 can be completely moved to the release position or only partially moved in the direction of the release position to form the avoidance of the ratchet wheel 71, and after the shelf plate 1 stops moving upward, the movable rod 72 is reset to the locking position under the action of the spring 722.

[0103] If the ratchet wheel 71 has a tendency to rotate counterclockwise in FIG. 7 (corresponding to the downward movement of the shelf 1), the ratchet wheel 71 cannot rotate under the locking of the movable rod 72, so that the gear 52 and the rack 51 cannot move relative to each other, avoiding the downward movement of the shelf 1 under the weight of the objects placed thereon.

[0104] When the movable rod 72 is in the release position, the rotation of the ratchet wheel 71 is not restricted and can be bidirectional, i.e., the shelf 1 can move upward or downward.

[0105] Of course, the locking and releasing of the ratchet wheel 71 by the movable rod 72 are not limited to the above-mentioned manner, and the movable rod 72 can also be arranged to move vertically close to and away from the ratchet wheel 71 to reach the locking position and the release position, or arranged to be horizontally arranged to move backward to the locking position and forward to the release position; or other arrangements that can achieve the locking and releasing of the ratchet wheel 71 by the movable rod 72, which are not described in detail here.

[0106] Further, the ratchet wheel 71 has an arc-shaped contour, and the end of the movable rod 72 close to the ratchet wheel 71 is provided with a circular sleeve 724 made of elastic material. When the movable rod 72 moves forward and then returns to the locking position under the restoring force of the spring 722, the arc-shaped ratchet wheel 71 has a small contact area with the movable rod 72, and the circular sleeve 724 provided at the end of the movable rod 72 close to the ratchet wheel 71 further reduces the contact area between the ratchet wheel 71 and the movable rod 72, so that the contact area between the ratchet wheel 71 and the movable rod 72 changes from the original surface contact to point contact, greatly reducing the noise generated by the impact of the movable rod 72 and the ratchet wheel 71; and the circular sleeve 724 made of elastic material serves as a buffer, further reducing the noise generated by the impact.

[0107] In some embodiments, as shown in FIG. 7, the limiting mechanism further includes a second limiting block 725 arranged at the end of the connecting piece 3 away from the ratchet wheel 71, the second limiting block 725 being provided with a second limiting hole through which the movable rod 72 passes; and a wrench 726 arranged at the end of the movable rod 72 away from the ratchet wheel 71, the wrench 726 having a rear end abutting against the front end of the second limiting block 725 when the movable rod 72 is in the locking position. By arranging the wrench 726 at the end of the movable rod 72 away from the ratchet wheel 71, the user can move the movable rod 72 from the locking position to the release position by holding the wrench 726 at the front end, facilitating the adjustment of the shelf 1.

[0108] In some embodiments, the diameter of the gear 52 is greater than the diameter of the synchronizing wheel 62, so that when the gear 52 rotates one turn, the synchronizing wheel 62 rotates more than one turn, and the ratchet wheel 71 coaxially arranged with the synchronizing wheel 62 also rotates more than one turn. That is, when the shelf 1 is adjusted to the same height, the greater the diameter of the gear 52, the greater the angle of rotation of the ratchet wheel 71, and the greater the number of teeth that can be locked by the angle of rotation of the ratchet wheel 71 in the adjustment height, and the greater the adjustment accuracy.

[0109] It should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
