[0029] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0030] As used herein, terms indicating spatial relative positions such as "upper," "above," "lower," and "below" are used for the purpose of convenience to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. Terms of spatial relative position may be intended to include different orientations of the device in use or operation in addition to the orientation shown in the drawings. For example, if the device in the figure is turned over, units described as being "below" or "beneath" other units or features will be located "above" the other units or features. Thus, the exemplary term "below" can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein interpreted accordingly.

[0031] See also Figure 1-2 , is a schematic structural diagram of a shelf assembly 100 provided in one embodiment of the present invention. The shelf assembly 100 can be applied in a box or on a door.

[0032] Preferably, the rack assembly 100 includes a rack body 10 and an adjustment assembly 20 arranged in cooperation with the rack body 10, the rack body 10 is used to store items, and the adjustment assembly 20 is used to adjust the height position of the rack body 10 in the vertical direction to adjust the storage space formed above the rack body 10 to accommodate items of different sizes.

[0033] Preferably, the adjustment component 20 includes a limit member 30 rotatably fixed to the rack body 10 via a rotating shaft 21, and a driving component 40 for driving the limit member 30 to rotate; the limit member 30 has a first part 31 and a second part 32 located on both sides of the rotating shaft 21, and the first part 31 is provided with a positioning protrusion 311 protruding outward to facilitate the installation and positioning of the rack body 10; the driving component 40 has a first elastic mechanism 43 arranged between the first part 31 and the rack body 10, a driving block 42 cooperating with the second part 32 to drive the second part 32 to move, and a reset mechanism 41 arranged between the driving block 42 and the rack body 10.

[0034] In this way, the function of multi-level adjustment of the rack body 10 in a small range can be realized, thereby meeting the user's demand for a wider range of space sizes; at the same time, the rack assembly 100 needs to be driven and adjusted by the drive block 42 before the rack body 10 can be removed, which can prevent children from easily removing it and improve safety.

[0035] In this embodiment, refer to Figure 3-7As shown, the shelf body 10 is a drawer-shaped receiving space, and the shelf body 10 includes side walls 11 located on both sides in the horizontal direction, and the side walls 11 define a receiving space 110, and the receiving space 110 is open to both sides, and the adjustment component 20 is arranged in the receiving space 110; the shelf body 10 also includes a rear wall 12 connecting the two side walls 11. In other embodiments, the adjustment component 20 can also be arranged on the rear wall 12.

[0036] The stopper 30 is fixed to the side wall 11 via the rotating shaft 21, the positioning protrusion 311 has a positioning state protruding out of the receiving space 110 and an adjustment state rotating to be located in the receiving space 110, and the end of the second portion 32 is provided with a first inclined surface 321 abutting against the second inclined surface of the driving block 42. In this way, the stopper 30 is driven to rotate.

[0037] Specifically, the rotation shaft 21 passes through the middle part of the stopper 30 and the two ends of the rotation shaft 21 are fixed to the side wall 11. The stopper 30 can rotate around the rotation shaft 21. In this way, no matter the first part 31 or the second part 32 of the stopper 30 is rotated by force, the other part will be driven to rotate counterclockwise or clockwise at the same time. In this embodiment, the first inclined surface 321 of the second part 32 is arranged toward the driving block 42 and abuts against the second inclined surface of the driving block 42. In this way, when the driving block 42 moves downward, it abuts against the second part 32 to move outward, thereby driving the first part 41 to rotate.

[0038] The positioning protrusion 311 protrudes out of the receiving space 110 and cooperates with the box or door to realize the positioning of the rack body 10. When the positioning protrusion 311 rotates into the receiving space 110, the positioning protrusion 311 cannot cooperate with the box or door, and the rack body 10 can be adjusted in the vertical height direction. The minimum single adjustment value of the rack body 10 is in the range of 10-30mm. A small range of height adjustment is realized to adapt to the height of more items.

[0039] Specifically, the initial state of the limit member 30 is the positioning state, the first inclined surface 321 of the limit member 30 abuts against the driving block 42, and the positioning protrusion 311 of the limit member 30 abuts against the door body or the box body to maintain force balance and achieve stable positioning.

[0040] Preferably, the reset mechanism 41 is a first spring arranged in the vertical direction, the bottom end of the first spring is fixed to the side wall 11, and the top end of the first spring is connected to the driving block 42. In this way, when the driving block 42 is forced to move downward, the first spring is compressed and has elastic force, and when the driving block 42 is not forced, the first spring returns to its original shape and presses the driving block 42 upward, so that the driving block 42 returns to its original position.

[0041] Preferably, the driving block 42 is assembled into the receiving space 110 from top to bottom, and the driving block 42 has an operating portion 421 exposed above the side wall and an abutment portion 422 located in the receiving space 110, and the abutment portion 422 includes a second inclined surface 423 arranged toward the limit member 30 and a bottom 424, and the top end of the reset mechanism 41 abuts against the bottom 424.

[0042] Specifically, the driving block 42 faces the limit member 30 along one side in the horizontal direction and is provided with a second inclined surface 423. The second inclined surface 423 is wide at the top and narrow at the bottom, and the first inclined surface 321 is narrow at the top and wide at the bottom. In this way, when the second inclined surface 423 moves downward vertically, it will also abut the first inclined surface 321 to generate a horizontal force, thereby pushing the second part 32 to rotate; the driving block 42 faces the side wall 11 along the other side in the horizontal direction and is provided with a guide wall 425. The accommodating space 110 is provided with a guide groove 111 corresponding to the guide wall 425. The guide wall 425 moves along the guide groove 111, which is more stable.

[0043] The drive block 42 is provided with a buckle 426 on the side along the front-to-back direction, and the inner wall surface of the receiving space 110 is provided with a slide groove 112, and the buckle 426 abuts against the wall surface of the slide groove 112 upwards; the drive block 42 is limited to prevent the drive block 42 from upwardly escaping from the receiving space; the reset mechanism 41 abuts against the bottom 424 of the drive block 42 upwards, limits the drive block 42 and provides a reset elastic force.

[0044] Reference Figure 7 As shown, the driving block 42 is pressed downward, and the second inclined surface 423 slides against the first inclined surface 321 of the stopper 31, driving the second part 32 of the stopper to rotate outward, driving the positioning protrusion 311 to rotate inward to be located in the receiving space 110, and at the same time, the bottom 424 downwardly abuts against the reset mechanism 41, and the reset mechanism 41 has elastic force. It is worth noting that the first elastic mechanism 43 is also provided in this case, and when the positioning protrusion 311 rotates inward, it will also compress the first elastic mechanism 43 to make it have elastic force.

[0045] The pressing of the driving block 42 is released, and the reset mechanism 41 applies force to push the driving block 42 upward, and the first inclined surface 321 is no longer subject to the downward pressure of the second inclined surface 423, and the first elastic mechanism 43 has elastic force to apply force to the positioning protrusion 321, so that the positioning protrusion 311 rotates outward to the positioning state, and at the same time, the second part 32 rotates inward and can also press the second inclined surface 423, so that the driving block 42 moves upward to the initial state. In this way, the positioning and height adjustment of the shelf body 10 can be achieved.

[0046] In other embodiments, the first elastic mechanism 43 can also be eliminated as long as the upward pressure exerted by the second inclined surface 423 on the first inclined surface 321 is smaller than the gravity exerted by the second portion 32 falling back downward. In this way, even if the first inclined surface 321 is still subjected to the pressure exerted by the upward movement of the second inclined surface 423, due to the small pressure, the first inclined surface 321 will still fall back along the second inclined surface 423 due to gravity, thereby rotating inward, thereby driving the positioning protrusion 311 to rotate outward.

[0047] Preferably, the adjustment assembly 20 includes a decorative cover 50 covering the receiving space 110 , the decorative cover 50 is snapped into the receiving space 110 , and the outer side surface of the decorative cover 50 is flush with the outer side surface of the side wall 11 .

[0048] The present invention also includes a refrigeration device, such as a refrigerator, which includes the above-mentioned shelf assembly 100. Specifically, the refrigerator includes a box body and a door body. The box body can be correspondingly provided with the above-mentioned shelf assembly 100 that can be adjusted in a small range, and the door body can also be correspondingly provided with the above-mentioned shelf assembly 100 that can be adjusted in a small range. Figure 8-9 As shown, users can configure according to their needs.

[0049] Preferably, the refrigerator includes a positioning groove 200 that is arranged in cooperation with the shelf assembly 100, and the positioning groove 200 is abutted against the positioning protrusion 311 to achieve installation and positioning, and the distance between adjacent positioning grooves 200 along the height direction of the refrigerator is between 10-30 mm. Specifically, the distance between the positioning grooves 200 refers to the distance between the bottoms or tops of two adjacent positioning grooves 200, that is, the positioning protrusion 311 adjusts the required distance between adjacent positioning grooves 200.

[0050] Preferably, the box body and / or the door body are integrally formed with the positioning groove 200 ; or, the box body and / or the door body are provided with an adjustment base, and the adjustment base is provided with the positioning groove 200 .

[0051] In a specific embodiment, the shelf assembly 100 is applied to a door body. When the door body is foamed, the adjustment base provided with a positioning groove 200 is integrated into the door body lining, and the door body is foamed as a whole, or the door body lining is integrally formed with the positioning groove 200, and the box body is arranged in the same manner.

[0052] Preferably, each of the positioning grooves 200 includes a first abutment plane 201 and a first guide slope 202, and the positioning protrusion 311 includes a second abutment plane 312 and a second guide slope 313. When the positioning protrusion 311 is in a positioning state, the second abutment plane 312 abuts against the first abutment plane 201; the second guide slope 313 abuts upward against and slides over the first guide slope 202, so that the positioning protrusion 311 slides out of the positioning groove 200.

[0053] The installation process and adjustment process of the rack assembly 100 will be briefly described below, and only the assembly steps of one side of the rack assembly 100 are shown, and the other side is the same.

[0054] First, fix the reset mechanism 41 to the corresponding position of the accommodating space 110, and install the driving block 42 from top to bottom, so that the top of the reset mechanism 41 is connected to the bottom 424 of the driving block 42, the guide wall 425 will slide along the guide groove, and the buckle 426 will limit the driving block 42; then, pre-place the first elastic mechanism 43 and the limiting member 30 in the corresponding position, so that one end of the first elastic mechanism 43 is fixed to the side wall, and the other end is connected to the inner side of the first part 31, and then assemble the rotating shaft 21 to the corresponding position of the side wall 11 for fixing the limiting member 30; finally, snap the decorative cover 50 onto the side wall of the shelf body 10 to cover the adjustment component 20 inside.

[0055] Reference Figure 7 As shown, the driving block 42 is pressed downward by hand, and then guided and abutted by the second inclined surface 423 and the first inclined surface 321, the limiting member 30 is pressed to rotate around the rotating shaft 21 by a certain angle, so that the positioning protrusion 321 protruding from the side wall 11 is retracted into the receiving space 110, so that the shelf body 10 can be moved up and down. At the same time, under the action of the reset mechanism 41 and the first elastic mechanism 43, the limiting member 30 and the driving block 42 can be reset to the original initial state after the hand is released.

[0056] It is understandable that when the shelf assembly 100 is inserted into the positioning slot 200 of the door body and / or the box body, the shelf assembly 100 can move directly upward for adjustment. Specifically, the second guide slope 313 abuts upward and slides over the first guide slope 202, so that the positioning protrusion 311 slides out of the positioning slot 200 for height adjustment.

[0057] However, since the second abutment plane 312 abuts against the first abutment plane 201 in the vertical direction, it cannot be adjusted downward directly. It is necessary to press the driving block 42 to retract the positioning protrusion 311 to the side wall 11 of the rack body 10, and the limit member 30 and the positioning groove 200 are released from the abutment and positioning. Then you can let go and the rack body 10 moves downward. When you hear a click, the rack body 10 is stuck in the positioning groove 200 of the lower level, thereby realizing the downward adjustment of the rack body 10.

[0058] If the shelf body 10 is to be removed from the door body and / or the box body, the only way is to press the drive block 42, retract the positioning protrusion 311 into the interior or slide the shelf body 10 through the uppermost positioning groove 200 to remove the shelf assembly 100. Children cannot easily remove the shelf body 10, thereby preventing the shelf body 10 from being easily removed and falling to injure children.

[0059] The beneficial effects of the present invention are as follows: the shelf body 10 can achieve multi-level adjustment in a small range of at least 10 mm; the shelf assembly 100 can be removed only after pressing the drive block 42 or moving the shelf assembly 100 to the top, thereby preventing children from accidentally touching or getting hurt.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
