Abstract
Description
Technical Field
[0001] This application relates to the field of refrigeration equipment technology, and more particularly to a shelf assembly and a refrigeration device provided with the shelf assembly. Background Technology
[0002] With the development of technology, existing refrigerators have improved the adjustment of the shelf position in the refrigeration compartment, providing a shelf assembly in which the shelf can move up and down. The shelf has an adjustment mechanism on the side. To avoid the influence of dust and other factors on the smoothness of the adjustment mechanism and for aesthetic reasons, researchers have set decorative shells on the adjustment mechanisms on both sides of the shelf and opened adjustment holes on the decorative shells for the shelf to move. In addition, decorative pieces that move with the shelf are set on the inside of the decorative shells, so that the exposed adjustment holes can be covered when the shelf moves to maintain the appearance.
[0003] However, since the connection between the shelf and the adjustment mechanism is mostly in the form of a hanging groove, the shelf needs to be lifted and then lowered to hook the hanging groove during installation. Therefore, a clearance notch needs to be reserved on the decorative plate for the shelf installation. The clearance notch will still affect the appearance of the shelf assembly, exposing the adjustment mechanism inside the decorative shell. Dust can also enter the decorative shell through the clearance notch, affecting the smoothness of the adjustment mechanism. Summary of the Invention

These terms are only used to distinguish these objects from one another. For example, a first decorative piece may be referred to as a second decorative piece, and similarly, a second decorative piece may be referred to as a first decorative piece, without departing from the scope of protection of this application.
[0052] This application provides a shelf assembly that can be used in refrigeration equipment. The refrigeration equipment equipped with the shelf assembly includes a housing with a refrigeration compartment and the shelf assembly disposed in the refrigeration compartment. Therefore, this application also provides a refrigeration equipment equipped with the aforementioned shelf assembly.
[0053] like Figures 1-3 As shown, the shelf assembly includes a shelf 1, an adjustment mechanism, and a decorative structure. The shelf 1 can move along a first direction. In this application, the shelf 1 is only a... Figure 1The shelf is movable in the middle and lower part; the adjustment mechanism is set on the side of the shelf 1, the adjustment mechanism includes a slide rail 2 and a connecting member connected to the slide rail 2, the connecting member is connected to the shelf 1; 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 in 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 set on the side of the adjustment hole 511 away from the shelf 1 and moves together with the shelf 1, the decorative piece 52 includes a decorative body 5211 with a notch, a relief piece 5212 set at the notch and a first elastic member connecting the decorative body 5211 and the relief piece 5212, the notch of the decorative body 5211 is located above the shelf 1 and is set close to the shelf 1 in the first direction, the first elastic member makes the relief piece 5212 include a first state in which it is located on the same plane as the decorative body 5211 and a second state in which it is flipped toward the slide rail 2.
[0054] It should be noted that this article describes the shelf assembly in its normal use state, that is, the shelf 1 is roughly horizontal, the first direction of movement of the shelf 1 is roughly vertical, and up and down are common directional terms in the vertical direction. In addition, the illustration in this application shows that the adjustment mechanism is located on the rear side of the shelf 1. When the user faces the shelf assembly, the side closer to the user is the front side, and the second direction is the front and back direction.
[0055] Shelf 1 is connected to slide rail 2 via connecting members, allowing it to move vertically and thus adjust its height. Main decorative shell 51 includes slide rail 2, giving the shelf assembly a pleasing appearance. Adjustment holes 511 are provided on the main decorative shell 51 to allow the shelf 1 to move vertically. The main decorative shell 51 has a roughly C-shaped cross-section, covering the two sides and front of slide rail 2. A decorative piece 52 is located on the side of the adjustment hole 511 facing away from the shelf 1, i.e., inside the main decorative shell 51, and moves with the shelf 1 to cover the adjustment hole 511.
[0056] The connecting member passes through the adjustment hole 511. The connecting member is composed of multiple parts, one of which is connected to the shelf 1 and the other part is connected to the slide rail 2. The connection is achieved through the adjustment hole 511. A notch is provided in the decorative body 5211 of the decorative piece 52 to make way for the shelf 1 with some parts of the connecting member during installation. The vacating piece 5212 is in the second state during the installation of the shelf 1, flipped towards the slide rail 2. After the shelf 1 is installed, or when the shelf 1 is not installed, the vacating piece 5212 is in the first state, located on the same plane as the decorative body 5211. The decorative body 5211 and the vacating piece 5212 together cover the adjustment hole 511.
[0057] In some embodiments, such as Figure 3To accommodate the decorative piece 52 when the spacer piece 5212 is in the first state, the decorative piece 52 also includes a pivot 5214. The decorative body 5211 is provided with a first transition hole 5211a, the spacer piece 5212 is provided with a second transition hole 5212a, the first elastic element is a torsion spring, and the torsion spring that serves as the first elastic element is called the first torsion spring 5213. The pivot 5214 passes through the first transition hole 5211a, the second transition hole 5212a and the first torsion spring 5213.
[0058] The first transition hole 5211a and the second transition hole 5212a are both formed on the protrusions extending from the decorative body 5211 and the relief piece 5212, so as to facilitate the passage of the rotating shaft 5214 through the first transition hole 5211a and the second transition hole 5212a. When the relief piece 5212 is in the first state, the first torsion spring 5213 is not under force, and its two ends are only in contact with the decorative body 5211 and the relief piece 5212; after the first torsion spring 5213 is subjected to external force, the relief piece 5212 rotates around the rotating shaft 5214 as the axis to switch to the second state. When the external force is removed, the relief piece 5212 returns to the first state under the action of the elastic restoring force of the first torsion spring 5213.
[0059] Of course, the first elastic element can also be other structures with elastic force, such as the relief plate 5212. This application uses a torsion spring as an example for illustration.
[0060] In some embodiments, the slide rail 2 is provided with a slide groove 21; the connecting member includes a connector 31 for connecting with the shelf 1, a pulley 32 that cooperates with the slide groove 21, and a converter 33 that connects the pulley 32 and the connector 31; the decorative piece 52 includes a first decorative piece 521 and a second decorative piece 522 located above and below the shelf 1, respectively, and both the first decorative piece 521 and the second decorative piece 522 are connected to the converter 33.
[0061] The connector 31 is connected to the side of the shelf 1 and to the adapter 33; the slide rail 2 is provided with a slide groove 21, the pulley 32 is disposed in the slide groove 21 and moves along the slide groove 21, the adapter 33 is provided with a connecting hole 333, and the pulley 32 is connected to the adapter 33 through the connecting hole 333. Figure 2 The pulley 32 referred to by reference numeral 32 is only a part of the pulley 32; the rest is covered by the adapter 33. The decorative piece 52 is divided into a first decorative piece 521 located above the shelf 1 and a second decorative piece 522 located below the shelf 1. This effectively divides a long decorative piece 52 into two shorter pieces, increasing the flexibility of the decorative piece 52 and preventing the longer piece from bending due to the downward deflection of the front end of the shelf 1. Since the clearance piece 5212 is located above the partition, the clearance piece 5212, the first elastic element, and the pivot 5214 are all part of the first decorative piece 521. The first decorative piece 521 and the second decorative piece 522 are connected to the adapter 33 to achieve synchronous movement with the shelf 1.
[0062] In some embodiments, the adapter 33 is provided with a first snap-fit portion 334 and a second snap-fit portion 335 at its top and bottom, respectively; the first decorative piece 521 and the second decorative piece 522 are provided with a first clamping portion 5215 and a second clamping portion 5221, respectively, wherein the first clamping portion 5215 clamps the first snap-fit portion 334 and the second clamping portion 5221 clamps the second snap-fit portion 335.
[0063] The first clamping part 5215 of the first decorative piece 521 is disposed at the bottom of the first decorative piece 521, and the second clamping part 5221 of the second decorative piece 522 is disposed at the top of the second decorative piece 522. In the height direction, from top to bottom, they are the first decorative piece 521, the adapter 33, and the second decorative piece 522.
[0064] In some embodiments, the first latching portion 334 and the second latching portion 335 are respectively provided with a first latching hole 3341 and a second latching hole 3351; the first clamping portion 5215 and the second clamping portion 5221 each include two clamping plates spaced apart, the clamping plate of the first clamping portion 5215 is provided with at least one first protrusion 5215a, and the clamping plate of the second clamping portion 5221 is provided with at least one second protrusion 5221a; the first protrusion 5215a is disposed in the first latching hole 3341, and the second protrusion 5221a is disposed in the second latching hole 3351.
[0065] In some embodiments, the first snap-fit hole 3341 is larger than the first protrusion 5215a, and the second snap-fit hole 3351 is larger than the second protrusion 5221a.
[0066] Specifically, such as Figures 4-6 In the first clamping part 5215, one of the clamping plates is longer than the other clamping plate. The part of the longer clamping plate that protrudes from the other clamping plate is provided with a first protrusion 5215a. The first protrusion 5215a is located on the side of the clamping plate closer to the other clamping plate. That is, in the spacing direction between the two clamping plates of the first clamping part 5215, the first protrusion 5215a is located between the two clamping plates.
[0067] When the first decorative piece 521 is connected to the adapter 33, the first snap-fit portion 334 at the top of the adapter 33 is located between the two clamping plates of the first clamping portion 5215, and the first protrusion 5215a extends into the first snap-fit hole 3341 of the first snap-fit portion 334. Since the first snap-fit hole 3341 is larger than the first protrusion 5215a, 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 amount of deflection of the first decorative piece when the front end of the shelf 1 deflects downward.
[0068] Similarly, one of the clamping plates of the second clamping part 5221 is also longer. The portion of the longer clamping plate that protrudes from the other clamping plate is provided with a second protrusion 5221a. The second protrusion 5221a is also 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 second clamping part 5221, the second protrusion 5221a is located between the two clamping plates.
[0069] When the second decorative piece 522 is connected to the adapter 33, the second snap-fit portion 335 at the bottom of the adapter 33 is disposed between the two clamping plates of the second clamping portion 5221, and the second protrusion 5221a extends into the second snap-fit hole 3351 of the second snap-fit portion 335. Since the second snap-fit 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 amount of deflection of the second decorative piece when the front end of the shelf 1 deflects downward.
[0070] like Figure 4 In this configuration, the first protrusion 5215a and the second protrusion 5221a extend into the first snap-fit hole 3341 and the second snap-fit hole 3351 from the same side of the adapter 33. However, this is only one example; the first protrusion 5215a and the second protrusion 5221a can also be provided on clamping plates on different sides of the adapter 33, thereby extending into the first snap-fit hole 3341 and the second snap-fit hole 3351 from different sides of the adapter 33. Furthermore, the first protrusion 5215a / second protrusion 5221a can also be provided on both clamping plates of the first clamping portion 5215 / second clamping portion 5221.
[0071] In some embodiments, the main decorative shell 51 is provided with a stop 512 on the side of the adjustment hole 511 away from the shelf. The stop 512 is provided along the length direction of the main decorative shell 51 and is spaced apart from the adjustment hole 511 in a second direction.
[0072] like Figure 7 In the middle, the stop members 512 above and below the adjustment hole 511 are relatively wide. The stop members 512 at the same height as the adjustment hole 511 are relatively narrow to avoid obstructing the adjustment of the shelf 1. The stop members 512 are spaced apart from the front side of the main decorative shell 51. The first decorative piece 521 and the second decorative piece 522 are disposed between the stop members 512 and the front side of the main decorative shell 51 to guide the first decorative piece 521 and the second decorative piece 522 and prevent the first decorative piece 521 and the second decorative piece 522 from tilting backward.
[0073] In some embodiments, the adapter 33 is provided with a fixing post for connecting to the connector 31. The fixing post is located on the side of the pulley 32 near the shelf 1 and is spaced apart from the pulley 32 in a second direction.
[0074] Fixed post for connection with connector 31 Figure 2 The second fixing post 332 shown in the diagram is located on the side of the pulley 32 near the shelf 1, that is, the fixing post is located in front of the pulley 32. After the shelf 1 is installed, the front end is prone to tilting downward. The fixing post serves as the center of rotation of the shelf 1 after it bears the load. It is further forward than the pulley 32, which reduces the lever arm of the shelf 1 and increases the load-bearing capacity of the shelf 1.
[0075] In some embodiments, such as Figure 8 , 9 The fixing column includes a first fixing column 331 and a second fixing column 332 arranged from top to bottom. The connector 31 is provided with a first hanging groove 311 and a second hanging groove 312 arranged from top to bottom. The first hanging groove 311 opens downward and the second hanging groove 312 opens towards the slide rail 2. The first hanging groove 311 and the second hanging groove 312 are hung on the first fixing column 331 and the second fixing column 332.
[0076] The first hanging groove 311 and the second hanging groove 312 on the connector 31 are not both open downwards. Instead, the first hanging groove 311 opens downwards, and the second hanging groove 312 opens towards the slide rail 2. Thus, when installing the shelf 1, it is only necessary to hang the first hanging groove 311 on the first fixed post 331 first, and then rotate the shelf 1 to hang the second hanging groove 312 on the second fixed post 332, without having to lift and lower the shelf 1 as a whole. There are no restrictions on the structure above the first fixed post 331 and the second fixed post 332. Furthermore, when the shelf assembly is height-adjusted via gear 35 and rack 34 as described below, and a damping member 36 is provided for the gear 35, the engagement method of the hanging groove and the fixed post in this application will not be affected by the damping member 36 due to the need to lift and lower the shelf 1, thus not affecting the installation speed of the workers.
[0077] In some embodiments, the distance between the axis of the fixed column and the axis of the pulley 32 in the front-back direction is 10-60 mm. The connector 31 and the adapter 33 are connected to the fixed column through the hanging groove. The axis of the fixed column is the connection center of the connector 31 and the adapter 33. By controlling the distance between the axis of the fixed column and the axis of the pulley 32 in the front-back direction to be between 10-60 mm, the lever arm of the shelf 1 can be reduced, thereby increasing the load-bearing capacity of the shelf 1. It can 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-back direction of the shelf assembly, which would reduce the width of the shelf 1 in the front-back direction.
[0078] In some embodiments, the distance between the axis of the fixed column and the axis of the pulley 32 can be 37.8 mm, or it can be an integer such as 37 mm or 38 mm, or it can be set to 35 mm, 40 mm, etc.
[0079] In some embodiments, such as Figure 9The shelf assembly also 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, that is, the locking mechanism 4 can prevent the second hanging slot 312 from falling off the second fixing post 332 due to shaking of the shelf 1 caused by external factors.
[0080] In some embodiments, the locking mechanism 4 includes a central shaft 41 connected to the connecting member 31, a locking member 42 that rotates along the central shaft 41, and a second elastic member that deforms as the locking member 42 rotates. The second elastic member is in a locked state when it is not under force.
[0081] The central shaft 41, connected to the connector 31, is positioned near the second hanging groove 312. The locking member 42 is sleeved on the central shaft 41 to achieve rotation around the central shaft 41. When the locking member 42 rotates, it causes the second elastic member to deform. When the second elastic member is not under force, the locking mechanism 4 is in the locked state, that is, at this time, the locking member 42 blocks the side of the second fixed post 332 near 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 side of the second fixed post 332 near the slide rail 2 is not blocked, the second elastic member is deformed under force, and the locking mechanism 4 is in the unlocked state. This state is when the shelf 1 is installed or removed, and the locking member 42 makes room for the second hanging groove 312 to hang on the second fixed post 332, or the locking member 42 makes room for the second hanging groove 312 to disengage from the second fixed post 332.
[0082] In some embodiments, such as Figure 10 In this application, the shelf assembly also includes a first side decorative shell 8 wrapped around the side of the connector 31, one end of the second 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.
[0083] The first decorative shell 8 is wrapped around the side of the connector 31 to completely cover the components connected to the connector 31 to ensure aesthetics. That is, the first decorative shell 8 is relatively stationary relative to the connector 31. One end of the second elastic member is fixed relative to the first 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 second elastic member is compressed or stretched, thereby realizing the switching of the locking mechanism 4 between the locked state and the unlocked state.
[0084] The shelf assembly provided in this application also includes a second decorative shell 9 that wraps around the other side of the connector 31. A cavity is formed between the first decorative shell 8 and the second decorative shell to wrap the connector 31 and the components on both sides of the connector, thus ensuring the aesthetics of the shelf assembly.
[0085] In some embodiments, such as Figure 9 In this design, the second elastic element is a torsion spring, which is referred to as the second torsion spring. The second torsion spring 43 includes a torsion spring body 431, a first end 432 and a second end 433 connected to both ends of the torsion spring body 431. The locking member 42 has a first ring portion 4221 with a notch protruding from the side facing the first side decorative shell 8, and a fixing groove 4222 communicating with the inner circle of the first ring portion 4221. The torsion spring body 431 is disposed inside the first ring portion 4221, the first end 432 extends out from the notch, and the second end 433 is disposed inside the fixing groove 4222. The first side decorative shell 8 is provided with a second ring portion 81 corresponding to the first ring portion 4221. The second ring portion 81 is sleeved outside the first ring portion 4221 and has a notch at the same position. The first end 432 also extends out from the notch of the second ring portion 81.
[0086] It should be noted here that, Figure 10 In order to make way for the gear 35 mentioned below, the second ring portion 81 is partially missing near the gear 35. However, this does not affect the function of the second ring portion 81. If the gear 35 is far enough away from the second ring portion 81, the second ring portion 81 will also have a unique notch at the notch formed by the first ring portion 4221.
[0087] The first annular portion 4221 formed by the locking member 42 can be sleeved on the central shaft 41 and rotated around the central shaft 41. The torsion spring body 431 of the second torsion spring 43 is also sleeved on the central shaft 41. 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 sequentially sleeved from the central shaft 41 outwards. The first annular portion 4221 and the second annular portion 81 are provided with notches at the same position, so that the first end 432 of the second torsion spring 43 protrudes from the notches of the first annular portion 4221 and the second annular portion 81. The second end 433 of the second torsion spring 43 is disposed in the fixing groove 4222 of the locking member 42.
[0088] When the locking mechanism 4 switches between the locked and unlocked states, the locking member 42 drives the second torsion spring 43 to rotate within the second annular portion 81. Thus, the first end 432 of the second torsion spring 43, protruding from the notch in the second annular portion 81, can only move slightly within the width of the notch. The second end 433 of the second torsion spring 43 rotates with the locking member 42, compressing or stretching the torsion spring body 431, causing the torsion spring body 431 to bear force. Of course, the width of the notch in the second annular portion 81 only needs to be sufficient for the first end 432 of the second torsion spring 43 to extend, or it can be slightly larger than the first end 432 of the second torsion spring 43; this is not a limitation.
[0089] 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, wherein the second locking member 422 drives the first locking member 421 to rotate.
[0090] The locking hook 4211 is used to block the second fixing post 332 from the side near the slide rail 2. The user moves the lever 4223 to rotate the second locking member 422. When installing the shelf 1, first hang the first hanging slot 311 on the first fixing post 331, and then rotate the shelf 1. Figure 9 In the middle, after the locking hook 4211 touches the second fixing post 332, it rotates downward under force, so that the second hanging slot 312 can be hung on the second fixing post 332. When it is necessary to remove the shelf 1, the lever 4223 is moved as follows. Figure 9 When the middle is turned counterclockwise, the second locking member 422 drives the first locking member 421 to rotate, and the locking hook 4211 moves aside, so that the second hanging groove 312 can disengage from the second fixing post 332, thereby removing the shelf 1.
[0091] In some embodiments, such as Figure 11 In this design, 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 sleeve hole 4212 for sleeved onto the central shaft 41. The second locking member 422 is sleeved onto the central shaft 41 through the first annular portion 4221. The edge of the second locking member 422 extends toward the first locking member 421 to form a fastening portion 4224. The shape of the fastening portion 4224 matches that of the first locking member 421, and the fastening portion 4224 abuts against the side of the first locking member 421.
[0092] When installing the locking mechanism 4, first fix the central shaft 41 to the connecting piece 31, then fit the first locking piece 421 onto the central shaft 41, and then fit the second torsion spring 43, which has its second end 433 fixed to the second locking piece 422, and the second locking piece 422 together onto the central shaft 41, ensuring that the first end 432 extends out from the first ring portion 4221. When installing the second locking piece 422, the fastening portion 4224 should be aligned with the first locking piece 421.
[0093] In some embodiments, the connecting member further 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 adjusting mechanism further includes a damping member 36 that provides damping force to the gear 35. The gear 35 meshes 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.
[0094] Since the shelf 1 in this application is installed by first hanging groove 311 on the first fixed post 331 and then rotating the shelf 1 so that the second hanging groove 312 is hung on the second fixed post 332, after the first hanging groove 311 is hung on the first fixed post 331, the gear 35 and the rack 34 are not yet engaged until the shelf 1 is rotated. At this time, there is no need to lift and lower the shelf 1. Therefore, the damping component 36 has no effect on the installation of the shelf 1 during the installation process and will not affect the time of the worker to install the shelf 1.
[0095] The damping member 36 includes a damping wheel 361 and a damper 362 that provides damping force to the damping wheel 361. The damping wheel 361 is detachably connected to the damper 362, and the damping wheel 361 meshes with the gear 35. The pitch circle radius r1 and the number of teeth z1 of the damping wheel 361 satisfy the following formula:
[0096]
[0097] Where k and b are constants in the relationship between damping and rotational speed of damper 362, g is the acceleration due to gravity, m is the preset load capacity of shelf 1, r2 is the pitch circle radius of gear 35, z2 is the number of teeth of gear 35, and v is the preset descent speed of shelf 1.
[0098] Since the rotational speed ω1 and number of teeth z1 of damping wheel 361 satisfy the rotational speed ω2 and number of teeth z2 of gear 35: ω1×z1=ω2×z2 (Formula 1), then If the descending speed v of shelf 1 is the linear velocity of gear 35, then the rotational speed of gear 35 is... If r2 is the pitch circle radius of gear 35, then
[0099] The damping force T of damper 362 is related to its rotational speed ω by a linear function T = kω + b. The rotational speed ω of damper 362 is equal to the rotational speed ω1 of damping wheel 361. The damping force output by damping wheel 361 is F = T / r1, where r1 is the pitch circle radius of damping wheel 361. Therefore, the downward acceleration of shelf 1... m represents 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; to maintain a constant descent speed of shelf 1, the descent acceleration a = 0, then...
[0100] Since gear 35 meshes with rack 34 and cannot be replaced, the only option is to change the pitch circle radius r1 and the number of teeth z1 of damping wheel 361. Furthermore, according to formula 4, if the load-bearing capacity of shelf 1 increases, the pitch circle radius r1 and / or the number of teeth z1 of damping wheel 361 need to be reduced.
[0101] In some embodiments, the connector 31 is provided with a through hole 313; such as Figure 12 In this design, the damping wheel 361 has a non-circular hole 3611, and the damper 362 has a non-circular cylinder 3621 that mates with the non-circular hole 3611. The damper 362 is fixed to the connector 31 and passes through the through hole 313, while the non-circular cylinder 3621 passes through the non-circular hole 3611, thus 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.
[0102] 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 located at both ends of the synchronization rod 61, the synchronization wheels 62 meshing with a gear 35. The limiting mechanism includes a ratchet 71 and a movable rod 72, the ratchet 71 being coaxially arranged with the synchronization wheels 62. Figure 2 In this configuration, gear 35, synchronizer pulley 62, and damping pulley 361 are located on the outside of connector 31, i.e., on the side opposite to shelf 1, while ratchet 71 is located on the inside of connector 31. For example... Figure 13 In the design, the ends of the synchronizing rod 61 are non-circular. The ratchet 71 is provided with a first non-circular groove 711 on the side near the synchronizing rod 61 to cooperate with the non-circular structures at both ends of the synchronizing rod 61. The ratchet 71 is provided with a non-circular protrusion 712 on the side near the synchronizing wheel 62. The synchronizing wheel 62 is provided with a second non-circular groove 621 on the side near the ratchet 71 to cooperate with the non-circular protrusion 712. The non-circular structure at the end of the synchronizing rod 61 is inserted into the first non-circular groove 711 of the ratchet 71. The non-circular protrusion 712 passes through the connector 31 and is provided in the second non-circular groove 621, so that the synchronizing wheels 62 at both ends of the synchronizing rod 61 mesh with the gears 35 on both sides of the shelf 1 respectively. When the shelf 1 moves up or down, the synchronization of the two sides is better.
[0103] In some embodiments, the movable lever 72 includes a locked position that engages with the ratchet 71 to limit the rotation of the ratchet 71 when the shelf 1 moves downward, and a released position after being disengaged from the ratchet 71. Figure 14 In the middle, since the adjustment mechanism is located near the rear side of the shelf 1, the movable rod 72 can move in the front and back direction and is provided with a convex ring 721; the limiting mechanism is also provided with a third elastic element 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 third elastic element abuts against the first limiting block 723 and the rear end abuts against the convex ring 721.
[0104] Two limiting members are provided, and the first limiting hole 7231 restricts the movable rod 72 to move only in the front-back direction. The third elastic member is preferably a spring 722, which is sleeved on the movable rod 72 and cooperates with the limiting member located 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, thus locking the position of the shelf 1.
[0105] When the movable lever 72 is in the locked position, if the ratchet 71 moves along... Figure 2 When rotated clockwise (corresponding to the upward movement of shelf 1), ratchet 71 pushes movable rod 72 forward. It should be noted that movable rod 72 can be fully moved to the release position or only partially moved in the direction of the release position to avoid ratchet 71. After shelf 1 stops moving upward, movable rod 72 returns to the locked position under the action of spring 722.
[0106] If the ratchet 71 has an edge Figure 2 The ratchet 71 cannot rotate due to the counterclockwise rotation (corresponding to the downward movement of shelf 1), and the gear 35 and rack 34 cannot move relative to each other, thus preventing shelf 1 from moving downward under the weight of the items placed on it.
[0107] When the movable lever 72 is in the released position, the ratchet 71 can rotate freely in both directions, meaning that the shelf 1 can move up or down.
[0108] Of course, the locking and releasing of the ratchet 71 by the movable lever 72 is not limited to the aforementioned methods. The movable lever 72 can also be set to move vertically to approach and move away from the ratchet 71 to reach the locking and releasing positions. It can also be set to move horizontally backward to the locking position and forward to the locking position. Other settings that can enable the movable lever 72 to lock and release the ratchet 71 will not be described in detail here.
[0109] Furthermore, the ratchet 71 has an arc-shaped outline, and a circular sleeve 724 made of elastic material is provided at the end of the movable lever 72 near the ratchet 71. When the movable lever 72 moves forward and returns to the locked position under the restoring force of the spring 722, the contact area between the arc-shaped ratchet 71 and the movable lever 72 is small. The circular sleeve 724 at the end of the movable lever 72 near the ratchet 71 further reduces the contact area between the ratchet 71 and the movable lever 72, changing the contact area between the ratchet 71 and the movable lever 72 from the original surface contact to point contact, which greatly reduces the noise generated by the impact between the movable lever 72 and the ratchet 71; and the circular sleeve 724 made of elastic material acts as a buffer, further reducing the noise generated by the impact.
[0110] In some embodiments, such as Figure 2 The limiting mechanism also includes a second limiting block 725 located at the end of the connecting member 31 away from the ratchet 71. The second limiting block 725 has a second limiting hole through which the movable rod 72 passes. A wrench 726 is located 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. By providing a wrench 726 at the end of the movable rod 72 away from the ratchet 71, the user can move the movable rod 72 from the locked position to the released position by grasping the wrench 726 at the front end, facilitating the adjustment of the shelf 1.
[0111] In some embodiments, the diameter of gear 35 is larger than the diameter of synchronous wheel 62. The larger diameter of gear 35 is larger than the diameter of synchronous wheel 62, so that when gear 35 rotates once, synchronous wheel 62 rotates more than once. Therefore, ratchet 71, which is coaxially arranged with synchronous wheel 62, also rotates more than once. That is, when the shelf 1 is adjusted to the same height, the larger the diameter of gear 35, the larger the angle of ratchet 71, the more teeth that ratchet 71 can lock within the adjustment height, and the greater the adjustment accuracy.
[0112] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
[0113] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this application and are not intended to limit the scope of protection of this application. All equivalent implementation methods or modifications made without departing from the spirit of the art of this application should be included within the scope of protection of this application.
