Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0046] Furthermore, it should be understood that although the terms "first," "second," etc. may be used herein to describe various elements or structures, these described objects should not be limited by these terms. These terms are merely used to distinguish the described objects from one another. For example, a first decorative sheet may be referred to as a second decorative sheet, and similarly, a second decorative sheet may be referred to as a first decorative sheet without departing from the scope of protection of this application.

[0047] An embodiment of the present application provides a shelf assembly that can be used in a refrigeration device. The refrigeration device equipped with the shelf assembly includes a box body equipped with a refrigeration compartment and a shelf assembly arranged in the refrigeration compartment. Therefore, the present application also provides a refrigeration device equipped with the aforementioned shelf assembly.

[0048] like Figure 1 、 2As shown, the shelf assembly includes a shelf 1 that can move along a first direction, an adjustment mechanism for adjusting the shelf 1 to move along the first direction, and a decorative structure that ensures aesthetics. The adjustment mechanism is arranged on the side of the shelf 1, and includes a slide rail 2 and a connecting member connected to the slide rail 2. The slide rail 2 is provided with a slide groove 21. The connecting member includes a connecting member 31 for connecting to the shelf 1, a pulley 32 cooperating with the slide groove 21, and an adapter 33 connecting the pulley 32 and the connecting member 31; the decorative structure includes a main decorative shell 51 and a decorative piece 52. The main decorative shell 51 wraps the slide rail 2 and is provided with an adjustment hole 511 extending along the first direction. The connecting member passes through the adjustment hole 511 and is connected to the slide rail 2. The decorative piece 52 is arranged on the side of the adjustment hole 511 away from the shelf 1, and is connected to the adapter 33 to move with the shelf 1. The decorative piece 52 includes a first decorative piece 521 and a second decorative piece 522 located above and below the shelf 1, respectively.

[0049] It should be noted that this article describes the shelf assembly in normal use, that is, the shelf 1 is arranged roughly horizontally, the first direction of movement of the shelf 1 is roughly vertical, and up and down are commonly used directional terms in the vertical direction. The illustration in this application shows that the adjustment mechanism is located on the rear side of the shelf 1, so when the user faces the shelf assembly, the side close to the user is the front side, and the second direction is the front-to-back direction.

[0050] The connecting member 31 is connected to the side of the shelf 1 and is connected to the adapter 33; the slide rail 2 is provided with a slide groove 21, the pulley 32 is provided in the slide groove 21 and moves along the slide groove 21, the adapter 33 is provided with a connecting hole 333, the pulley 32 is connected to the adapter 33 through the connecting hole 333, Figure 2 The pulley 32 indicated by the middle number 32 is only a part of the pulley 32 , and the rest of the pulley 32 is blocked by the adapter 33 .

[0051] The present application sets a first decorative sheet 521 and a second decorative sheet 522 above and below the shelf 1. The first decorative sheet 521 and the second decorative sheet 522 are connected to the adapter 33. When the shelf 1 moves in the vertical direction under the action of the adjustment mechanism, the first decorative sheet 521 and the second decorative sheet 522 move together with the movement of the shelf 1 to cover the part that cannot be covered by the adjustment hole 511. Figure 3 In the embodiment, the bottom of the first decorative piece 521 extends backward to form a convex block, which is open toward the front and downward to make way for the shelf 1 when it is installed.

[0052] In some embodiments, a first clamping portion 334 and a second clamping portion 335 are respectively provided at the top and bottom of the adapter 33; a first clamping portion 5211 and a second clamping portion 5221 are respectively provided at the first decorative sheet 521 and the second decorative sheet 522, the first clamping portion 5211 clamps the first clamping portion 334, and the second clamping portion 5221 clamps the second clamping portion 335.

[0053] The first clamping portion 5211 of the first decorative sheet 521 is arranged at the bottom of the first decorative sheet 521, and the second clamping portion 5221 of the second decorative sheet 522 is arranged at the top of the second decorative sheet 522. In the height direction, from top to bottom are the first decorative sheet 521, the adapter 33, and the second decorative sheet 522.

[0054] In some embodiments, the first clamping portion 334 and the second clamping portion 335 are respectively provided with a first clamping hole 3341 and a second clamping hole 3351; the first clamping portion 5211 and the second clamping portion 5221 each include two clamping plates arranged at intervals, the clamping plate of the first clamping portion 5211 is provided with at least one first protrusion 5211a, and the clamping plate of the second clamping portion 5221 is provided with at least one second protrusion 5221a; the first protrusion 5211a is provided in the first clamping hole 3341, and the second protrusion 5221a is provided in the second clamping hole 3351.

[0055] In some embodiments, the first engaging hole 3341 is larger than the first protrusion 5211 a , and the second engaging hole 3351 is larger than the second protrusion 5221 a .

[0056] Specifically, such as Figure 3 In the figure, the clamping plates are perpendicular to the first decorative piece 521 / the second decorative piece 522, one of the clamping plates of the first clamping portion 5211 is longer, and the first protrusion 5211a is provided on the part of the longer clamping plate protruding from the other clamping plate, and the first protrusion 5211a is provided on the side of the clamping plate close to the other clamping plate, that is, in the spacing direction of the two clamping plates of the first clamping portion 5211, the first protrusion 5211a is located between the two clamping plates.

[0057] When the first decorative piece 521 is connected to the adapter 33, the first clamping portion 334 on the top of the adapter 33 is arranged between the two clamping plates of the first clamping portion 5211, and the first protrusion 5211a extends into the first clamping hole 3341 of the first clamping portion 334. Since the first clamping hole 3341 is larger than the first protrusion 5211a, the connection between the first decorative piece 521 and the adapter 33 is not completely fixed, but can achieve a small relative movement to offset the deflection of the first decorative piece when the front end of the shelf 1 deflects downward.

[0058] Similarly, one of the clamping plates of the second clamping portion 5221 is also longer, and the second protrusion 5221a is set on the part of the longer clamping plate that protrudes from the other clamping plate, and the second protrusion 5221a is also set on the side of the clamping plate close to the other clamping plate, that is, in the spacing direction of the two clamping plates of the second clamping portion 5221, the second protrusion 5221a is located between the two clamping plates.

[0059] When the second decorative piece 522 is connected to the adapter 33, the second clamping portion 335 at the bottom of the adapter 33 is arranged between the two clamping plates of the second clamping portion 5221, and the second protrusion 5221a extends into the second clamping hole 3351 of the second clamping portion 335. Since the second clamping hole 3351 is larger than the second protrusion 5221a, the connection between the second decorative piece 522 and the adapter 33 is not completely fixed, but can achieve a small relative movement to offset the deflection of the second decorative piece when the front end of the shelf 1 deflects downward.

[0060] like Figure 3 In the embodiment, the first protrusion 5211a and the second protrusion 5221a extend from the same side of the adapter 33 into the first engaging hole 3341 and the second engaging hole 3351. However, this is merely an example. The first protrusion 5211a and the second protrusion 5221a may be disposed on the clamping plates on different sides of the adapter 33, thereby extending from different sides of the adapter 33 into the first engaging hole 3341 and the second engaging hole 3351. Furthermore, the first protrusion 5211a and the second protrusion 5221a may be disposed on both clamping plates of the first clamping portion 5211 and the second clamping portion 5221.

[0061] In some embodiments, a stopper 512 is provided on the side of the main decorative shell 51 away from the shelf at the adjustment hole 511 . The stopper 512 is provided along the length direction of the main decorative shell 51 and spaced apart from the adjustment hole 511 in the second direction.

[0062] like Figure 4 In the figure, the stoppers 512 above and below the adjustment hole 511 are wider, and the stoppers 512 at the same height as the adjustment hole 511 are set narrower to avoid obstructing the adjustment of the shelf 1. The stoppers 512 are spaced from the front side of the main decorative shell 51, and the first decorative sheet 521 and the second decorative sheet 522 are set between the stoppers 512 and the front side of the main decorative shell 51 to guide the first decorative sheet 521 and the second decorative sheet 522 and prevent the first decorative sheet 521 and the second decorative sheet 522 from tipping backwards.

[0063] In some embodiments, the adapter 33 is provided with a fixing column for connecting to the connecting member 31 , and the fixing column is located on the side of the pulley 32 close to the shelf 1 and is spaced apart from the pulley 32 in the second direction.

[0064] A fixing column ( Figure 2 The second fixing post 332 (shown in the figure) is located on the side of the pulley 32 closer to the shelf 1, that is, the fixing post is located in front of the pulley 32. After installation, the front end of the shelf 1 tends to tilt downward. The fixing post serves as the center of rotation of the shelf 1 under load. It is located further forward of the pulley 32, which reduces the moment arm of the shelf 1's rotation and increases the load-bearing capacity of the shelf 1.

[0065] In some embodiments, as Figure 5 、 6 The fixed column includes a first fixed column 331 and a second fixed column 332 spaced apart along the first direction. The connecting member 31 is provided with a first hanging groove 311 and a second hanging groove 312 spaced apart along the first direction. The first hanging groove 311 opens downward, and the second hanging groove 312 opens toward the slide rail 2. The first hanging groove 311 and the second hanging groove 312 are hung on the first fixed column 331 and the second fixed column 332.

[0066] The first hanging slot 311 and the second hanging slot 312 on the connecting member 31 are not both open downward, but the first hanging slot 311 opens downward, and the second hanging slot 312 opens toward the slide rail 2. In this way, when installing the shelf 1, it is only necessary to hang the first hanging slot 311 on the first fixed column 331 first, and then rotate the shelf 1 to hang the second hanging slot 312 on the second fixed column 332, without having to lift and lower the entire shelf 1. There is no restriction on the structure above the first fixed column 331 and the second fixed column 332. Moreover, when the shelf assembly is height-adjusted by the gear 35 and the rack 34 as described below, and the gear 35 is provided with a damping member 36, the coordination of the hanging slots and the fixed columns in this application will not affect the installation speed of the workers due to the damping member 36 being affected by the shelf 1 needing to be lifted and lowered.

[0067] In some embodiments, the distance between the axis of the fixed column and the axis of the pulley 32 in the front-to-back direction is 10 to 60 mm. The connector 31 and the adapter 33 are connected to the fixed column via a hanging slot, and the axis of the fixed column is the connection center of the connector 31 and the adapter 33. Controlling the distance between the axis of the fixed column and the axis of the pulley 32 in the front-to-back direction to be between 10 and 60 mm can both reduce the lever arm for the rotation of the shelf 1, thereby increasing the load-bearing capacity of the shelf 1; and also prevent the distance between the axis of the fixed column and the axis of the pulley 32 from occupying too much space in the front-to-back direction of the shelf assembly, thereby reducing the width of the shelf 1 in the front-to-back direction.

[0068] In some embodiments, the distance between the axis of the fixed column and the axis of the pulley 32 can be 37.8 mm. Of course, it can also be an integer such as 37 mm or 38 mm, or set to 35 mm, 40 mm, etc. on this basis.

[0069] In some embodiments, as Figure 6 In the embodiment, the shelf assembly further includes a locking mechanism 4 connected to the connector 31. The locking mechanism 4 includes a locked state in which the second fixing post 332 is blocked from the side of the slide rail 2, and an unlocked state in which the second fixing post 332 is not blocked from the side of the slide rail 2. The locking mechanism 4 can block the side of the second fixing post 332 from the slide rail 2. In other words, the locking mechanism 4 can prevent the second hanging groove 312 from falling out of the second fixing post 332 due to shaking of the shelf 1 due to external factors.

[0070] In some embodiments, the locking mechanism 4 includes a central shaft 41 connected to the connecting member 31, a locking member 42 rotating along the central shaft 41, and a first elastic member deformed as the locking member 42 rotates. The first elastic member is in a locked state when not under force.

[0071] The central axis 41 connected to the connecting member 31 is arranged near the second hanging groove 312. The locking member 42 is sleeved on the central axis 41 to achieve rotation about the central axis 41. When the locking member 42 rotates, it causes the first elastic member to deform. When the first elastic member is not subjected to force, the locking mechanism 4 is in a locked state. That is, at this time, the locking member 42 blocks the second fixing post 332 on the side close to the slide rail 2. This state is when the shelf 1 is installed and in normal use. If the locking member 42 rotates so that the second fixing post 332 on the side close to the slide rail 2 is not blocked, the first elastic member is deformed under force, and the locking mechanism 4 is in an unlocked state. This state is when the shelf 1 is installed or removed, the locking member 42 makes way for the second hanging groove 312 to be hooked to the second fixing post 332, or the locking member 42 makes way for the second hanging groove 312 to be separated from the second fixing post 332.

[0072] In some embodiments, as Figure 7 In the embodiment, the shelf assembly provided in the present application further includes a first side decorative shell 8 wrapped around the side of the connecting member 31, one end of the first elastic member is fixed relative to the first side decorative shell 8, and the other end is fixed to the locking member 42 and rotates with the rotation of the locking member 42.

[0073] The first side decorative shell 8 is wrapped around the side of the connecting member 31 to wrap all the parts connected to the connecting member 31 to ensure beauty, that is, the first side decorative shell 8 is relatively stationary relative to the connecting member 31, and one end of the first elastic member is fixed relative to the first side decorative shell 8, and the other end rotates with the rotation of the locking member 42. During the rotation of the locking member 42, the first elastic member can be subjected to force and compressed or stretched, thereby realizing the switching of the locking mechanism 4 between the locked state and the unlocked state.

[0074] The shelf assembly provided in this application also includes a second side decorative shell 9 wrapped around the other side of the connecting member 31. A cavity is formed between the first side decorative shell 8 and the second side decorative shell, which wraps the connecting member 31 and the components on both sides of the connection to ensure the aesthetics of the shelf assembly.

[0075] In some embodiments, as Figure 6In the figure, the first elastic member is a torsion spring, and the torsion spring 43 includes a torsion spring body 431, a first end 432 and a second end 433 connected to the two ends of the torsion spring body 431; the locking member 42 is provided with a first circular portion 4221 with a notch protruding toward the side of the first side decorative shell 8, and is also provided with a fixing groove 4222 connected to the inner circle of the first circular portion 4221, the torsion spring body 431 is arranged in the first circular portion 4221, the first end 432 extends from 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 portion 81 corresponding to the first circular portion 4221, the second circular portion 81 is sleeved on the outside of the first circular portion 4221 and is provided with a notch at the same position, and the first end 432 also extends from the notch of the second circular portion 81.

[0076] It should be noted here that, Figure 7 The second circular portion 81 is incomplete near the gear 35 to make room for the gear 35 described below, but this does not affect the role of the second circular portion 81. If the gear 35 is far enough away from the second circular portion 81, the second circular portion 81 will only have a single notch at the notch formed by the first circular portion 4221.

[0077] The first annular portion 4221 of the locking member 42 is capable of being sleeved on the central shaft 41 and rotatable 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 annular portion 81 is sleeved on the first annular portion 4221. That is, the spring body 722, the first annular portion 4221, and the second annular portion 81 are sleeved in sequence from the central shaft 41 outward. The first annular portion 4221 and the second annular portion 81 are provided with a notch at the same position, allowing the first end 432 of the torsion spring 43 to extend through the notch in the first annular portion 4221 and the second annular portion 81. The second end 433 of the torsion spring 43 is disposed within the fixing groove 4222 of the locking member 42.

[0078] When the locking mechanism 4 switches between the locked and unlocked states, the locking member 42 drives the torsion spring 43 to rotate within the second annular portion 81. As a result, the first end 432 of the torsion spring 43, since it extends from the notch of the second annular portion 81, can only move slightly within the width of the notch of the second annular portion 81. The second end 433 of the torsion spring 43 rotates with the rotation of the locking member 42, compressing or stretching the torsion spring body 431, thereby applying force to the torsion spring body 431. Of course, the width of the notch of the second annular portion 81 only needs to be wide enough for the first end 432 of the torsion spring 43 to extend, and may also be slightly wider than the first end 432 of the torsion spring 43. This is not a limitation herein.

[0079] In some embodiments, the locking member 42 includes a first locking member 421 provided with a locking hook 4211 and a second locking member 422 provided with a paddle 4223 , and the second locking member 422 drives the first locking member 421 to rotate.

[0080] The locking hook 4211 is used to block the second fixing column 332 from being close to the slide rail 2. The user turns the paddle 4223 to rotate the second locking member 422. When installing the shelf 1, first hang the first hanging groove 311 on the first fixing column 331, and then rotate the shelf 1. Figure 6 After the locking hook 4211 hits the second fixing column 332, it is forced to rotate downward so that the second hanging groove 312 can be hung on the second fixing column 332. When the shelf 1 needs to be removed, the paddle 4223 is moved as shown in FIG. Figure 6 When the handle is turned counterclockwise, the second locking member 422 drives the first locking member 421 to rotate, and the locking hook 4211 gives way, so that the second hanging groove 312 can be disengaged from the second fixing column 332, thereby removing the shelf 1.

[0081] In some embodiments, as Figure 8 In the embodiment, the second locking member 422 is fastened to the first locking member 421 and drives the first locking member 421 to rotate synchronously. The first annular portion 4221 and the fixing groove 4222 are provided on the second locking member 422. The first locking member 421 is provided with a socket hole 4212 that is sleeved onto the central shaft 41. The second locking member 422 is sleeved onto the central shaft 41 via the first annular portion 4221. The edge of the second locking member 422 extends toward the side of the first locking member 421 to form a snap-fitting portion 4224. The shape of the snap-fitting portion 4224 matches that of the first locking member 421 and the snap-fitting portion 4224 abuts against the side of the first locking member 421.

[0082] When installing the locking mechanism 4, first fix the central shaft 41 to the connecting member 31, sleeve the first locking member 421 onto the central shaft 41, and then sleeve the torsion spring 43 with the second end 433 fixed to the second locking member 422 and the second locking member 422 onto the central shaft 41 together, and ensure that the first end 432 extends from the first annular portion 4221. When installing the second locking member 422, align the buckling portion 4224 with the first locking member 421.

[0083] In some embodiments, the connecting member also includes a rack 34 fixed to the slide rail 2 and parallel to the slide groove 21, and a gear 35 rotatably connected to the connecting member 31. The adjustment mechanism also includes a damping member 36 that provides damping force for the gear 35. The gear 35 engages with the rack 34 to adjust the height of the shelf 1. The damping member 36 provides damping force when the shelf 1 moves downward to prevent the shelf 1 from falling rapidly under the action of gravity.

[0084] Since the installation method of the shelf 1 in this application is to hang the upper first hanging groove 311 on the first fixed column 331, and then rotate the shelf 1 to hang the second hanging groove 312 on the second fixed column 332, after the first hanging groove 311 is hung on the first fixed column 331, the gear 35 and the rack 34 are not engaged until the shelf 1 is rotated. At this time, there is no need to lift the shelf 1 up and then lower it. Therefore, during the installation process of the shelf 1, the damping component 36 has no effect on the installation of the shelf 1, and will not affect the time for workers to install the shelf 1.

[0085] The damping member 36 includes a damping wheel 361 and a damper 362 that provides damping force for the damping wheel 361. The damping wheel 361 is detachably connected to the damper 362, and the damping wheel 361 is meshed with the gear 35. The pitch circle radius r1 and the number of teeth z1 of the damping wheel 361 satisfy the following formula:

[0086]

[0087] Among them, k and b are constants in the relationship between the damping and speed of the damper 362, g is the acceleration of gravity, m is the preset load-bearing capacity of the shelf 1, r2 is the pitch circle radius of the gear 35, z2 is the number of teeth of the gear 35, and v is the preset descending speed of the shelf 1.

[0088] Since the speed ω1 and the number of teeth z1 of the damping wheel 361 and the speed ω2 and the number of teeth z2 of the gear 35 satisfy: ω1×z1=ω2×z2 (Formula 1), then The descending speed v of shelf 1 is the linear speed of gear 35, so the speed of gear 35 is r2 is the pitch circle radius of gear 35, then

[0089] The relationship between the damping T of the damper 362 and the rotation speed ω satisfies the linear function T = kω + b, the rotation speed ω of the damper 362 = the rotation speed ω1 of the damping wheel 361, the damping force F output by the damping wheel 361 = T / r1, r1 is the pitch circle radius of the damping wheel 361. Then the downward acceleration of the shelf 1 is m is the load-bearing capacity of shelf 1, specifically the sum of the weight of shelf 1 itself and the weight of the items placed on it; if you want to keep the descending speed of shelf 1 unchanged, the descending acceleration of shelf 1 a=0, then

[0090] Since gear 35 is meshed with rack 34 and cannot be replaced, the only changes are the pitch radius r1 and the number of teeth z1 of damping wheel 361. Furthermore, as shown in Formula 4, if the load capacity of shelf 1 increases, the pitch radius r1 and / or the number of teeth z1 of damping wheel 361 need to be reduced.

[0091] In some embodiments, the connecting member 31 is provided with a through hole 313; Figure 9 In the embodiment, the damping wheel 361 is provided with a non-circular hole 3611, and the damper 362 is provided with a non-circular cylinder 3621 that matches the non-circular hole 3611. The damper 362 is fixed to the connecting member 31 and passes through the through hole 313. The non-circular cylinder 3621 passes through the non-circular hole 3611, thereby connecting the damping wheel 361 and the damper 362. Therefore, the damping wheel 361 can be removed from the non-circular cylinder 3621 for replacement according to the load-bearing capacity of the shelf 1.

[0092] In some embodiments, the shelf assembly further includes a synchronization mechanism and a limiting mechanism. The synchronization mechanism includes a synchronization rod 61 and synchronization wheels 62 at both ends of the synchronization rod 61, and the synchronization wheels 62 are engaged with the gear 35; the limiting mechanism includes a ratchet 71 and a movable rod 72, and the ratchet 71 is coaxially arranged with the synchronization wheel 62. Figure 2 In the embodiment, the gear 35, the synchronous wheel 62 and the damping wheel 361 are arranged on the outside of the connecting member 31, that is, on the side away from the shelf 1, and the ratchet 71 is arranged on the inside of the connecting member 31. Figure 10 In the figure, both ends of the synchronization rod 61 are non-circular, and the ratchet 71 is close to the synchronization rod 61 and the non-circular structure at both ends of the synchronization rod 61 is matched to set a first non-circular groove 711, and the ratchet 71 is close to the synchronization wheel 62 and a non-circular protrusion 712 is provided on the side of the synchronization wheel 62 close to the ratchet 71, and the second non-circular groove 621 is provided corresponding to the non-circular protrusion 712. The non-circular structure at the end of the synchronization rod 61 is inserted into the first non-circular groove 711 of the ratchet 71, and the non-circular protrusion 712 is provided in the second non-circular groove 621 through the connecting piece 31, so that the synchronization wheels 62 at both ends of the synchronization rod 61 are respectively engaged with the gears 35 on both sides of the shelf 1. When the shelf 1 moves up or down, the adjustment synchronization of the two sides is better.

[0093] In some embodiments, the movable rod 72 includes a locking position for cooperating with the ratchet 71 to limit the rotation of the ratchet 71 when the shelf 1 moves downward, and a release position after being separated from the ratchet 71. Figure 11 In the figure, since the adjustment mechanism is arranged near the rear side of the shelf 1, the movable rod 72 can move in the front and rear directions and is provided with a convex ring 721; the limiting mechanism is also provided with a second elastic member and a first limiting block 723 connected to the connecting member 31, the first limiting block 723 is provided with a first limiting hole 7231 that matches the cross section of the movable rod 72, the movable rod 72 passes through the first limiting hole 7231, the front end of the second elastic member abuts against the first limiting block 723, and the rear end abuts against the convex ring 721.

[0094] Two limiting members are provided, and the first limiting hole 7231 is used to restrict the movable rod 72 to move only in the forward and backward directions. The second elastic member is preferably a spring 722, which is mounted on the movable rod 72 and cooperates with the limiting member at the front end. After the movable rod 72 is forced to move forward, the spring 722 is compressed. After the movable rod 72 loses its force, the restoring force of the spring 722 causes the movable rod 72 to move backward and cooperate with the ratchet 71 to lock the ratchet 71, thereby locking the relative movement of the gear 35 and the rack 34, thereby locking the position of the shelf 1.

[0095] When the movable rod 72 is in the locked position, if the ratchet wheel 71 moves along Figure 2 When the shelf 1 is rotated clockwise (corresponding to the upward movement of the shelf 1), the ratchet 71 pushes the movable rod 72 forward. It should 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 avoid the ratchet 71. After the shelf 1 stops moving upward, the movable rod 72 is reset to the locked position under the action of the spring 722.

[0096] If the ratchet 71 has Figure 2 In the counterclockwise rotation trend (corresponding to the downward movement of the shelf 1), the ratchet 71 cannot rotate under the locking of the movable rod 72, so that the gear 35 and the rack 34 cannot move relative to each other, preventing the shelf 1 from moving downward under the weight of the items placed thereon.

[0097] When the movable rod 72 is in the release position, the rotation of the ratchet wheel 71 is not restricted and can rotate in both directions, that is, the shelf 1 can move up or down.

[0098] Of course, the locking and releasing of the ratchet 71 by the movable rod 72 is not limited to the aforementioned method. The movable rod 72 can also be set to move vertically towards and away from the ratchet 71 to reach the locking position and the release position, or the movable rod 72 can be set horizontally to move backward to the locking position and forward to the locking position; or other setting methods that can realize the locking and releasing of the ratchet 71 by the movable rod 72 are not described in detail here.

[0099] Furthermore, the ratchet 71 has an arcuate profile, and a circular sleeve 724 is provided at one end of the movable rod 72 near the ratchet 71. The circular sleeve 724 is made of an elastic material. After the movable rod 72 moves forward and then returns to the locked position under the restoring force of the spring 722, the contact area between the arcuate ratchet 71 and the movable rod 72 is small. Providing the circular sleeve 724 at one end of the movable rod 72 near the ratchet 71 further reduces the contact area between the ratchet 71 and the movable rod 72, changing the contact area between the ratchet 71 and the movable rod 72 from the original surface contact to point contact, greatly reducing the noise generated by the collision between the movable rod 72 and the ratchet 71. The circular sleeve 724 made of elastic material acts as a buffer, further reducing the noise generated by the collision.

[0100] In some embodiments, as Figure 2 In the embodiment, the limiting mechanism further includes a second limiting block 725 provided at the end of the connecting member 31 away from the ratchet 71. The second limiting block 725 is provided with a second limiting hole, through which the movable rod 72 passes. A wrench 726 is provided at the end of the movable rod 72 away from the ratchet 71. When the movable rod 72 is in the locked position, the rear end of the wrench 726 abuts against the front end of the second limiting block 725. The wrench 726 is provided at the end of the movable rod 72 away from the ratchet 71. The user can grasp the wrench 726 at the front end to move the movable rod 72 from the locked position to the released position, thereby facilitating adjustment of the shelf 1.

[0101] In some embodiments, the diameter of the gear 35 is larger than the diameter of the synchronous wheel 62. The diameter of the gear 35 is larger than the diameter of the synchronous wheel 62, so that when the gear 35 rotates one circle, the synchronous wheel 62 rotates more than one circle, and the ratchet 71 coaxially arranged with the synchronous wheel 62 rotates more than one circle. That is, when the shelf 1 is adjusted to the same height, the larger the diameter of the gear 35, the larger the angle of rotation of the ratchet 71, the more teeth can be locked by the rotation angle of the ratchet 71 within the adjustment height, and the greater the adjustment accuracy.
