[0027] 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.

[0028] 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.

[0029] 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 to a box body or a door body.

[0030] 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.

[0031] Preferably, the adjustment assembly 20 includes a limit block 30 arranged in cooperation with the rack body 10 and a driving assembly 40 for driving the limit block 30 to move in the lateral direction. The driving assembly 40 includes an elastic member 41 arranged between the rack body 10 and the limit block 30 and a pressing block 42 pressing the limit block 30, and the pressing block 42 and the elastic member 41 can respectively drive the limit block 30 to move, so as to realize the lateral movement and reset of the limit block 30.

[0032] Reference Figure 3-7 As shown, the stopper 30 moves in the lateral direction, and the stopper 30 has a positioning state of protruding from the rack body 10, and an adjustment state of being retracted into the rack body 10. Preferably, the rack body 10 can be adjusted in height, and the minimum single adjustment value of the rack body 10 is in the range of 10-30 mm; in a specific embodiment, a small range of 10-15 mm height adjustment can be achieved.

[0033] In this way, the adjustment component 20 can realize the function of multi-level adjustment of the shelf body 10 in a small range, thereby meeting the user's demand for a wider range of space sizes; at the same time, the shelf assembly 100 needs to be driven and adjusted by the pressing block 42 before the shelf body 10 can be removed, which can prevent children from easily removing it and improve safety.

[0034] The rack body 10 is a drawer-shaped receiving space, which is used to be installed on a door body and / or a box body. The rack body 10 includes side walls 11 located on both sides in the horizontal direction, and the side walls 11 are provided with a receiving space 110, and the receiving space 110 is penetrated toward both sides to form a through hole, and the adjustment component 20 is arranged in the receiving space 110; the rack body 10 also includes a rear wall connecting the two side walls 11, and in other embodiments, the adjustment component 20 can also be arranged on the rear wall.

[0035] Preferably, the top of the pressing block 42 is exposed above the shelf body 10 and forms a pressing portion 421, the bottom of the pressing block 42 is provided with a first inclined surface structure 423, the limiting block 30 is provided with a second inclined surface structure 311 toward the first inclined surface structure 423, and the first inclined surface structure 423 is slidably abutted against the second inclined surface structure 311.

[0036] In this way, the first and second inclined structures 423 and 311 are set to abut each other, so that when the pressing block 42 moves vertically, the first inclined structure 423 applies an oblique force to the limit block 30, and the oblique force can be decomposed into vertical force and lateral force, thereby driving the limit block 30 to move horizontally.

[0037] Preferably, the two side walls of the pressing block 42 along the front-to-back direction extend downward to form extension walls 422 , and the bottom of the pressing block 42 includes two extension walls 422 spaced apart from each other. The inner surface of the extension wall 422 is a first inclined surface structure 423 .

[0038] Specifically, the extension walls 422 of the pressing block 42 are parallel to each other, and an avoidance space is formed between the two extension walls 422. When the pressing block 42 moves vertically, it avoids the limit block 30, allowing the limit block 30 to partially enter, so that the first inclined surface structure 423 of the extension wall 422 can slide and abut against the limit block 30.

[0039] Preferably, elastic hooks 424 and guide walls 425 are provided on both sides of the pressing block 42, and holding grooves and sliding grooves are provided on the inner wall surface of the receiving space 110 corresponding to the elastic hooks 424 and the guide walls 425, respectively, so as to facilitate the installation and movement guidance of the pressing block 42, make the movement more stable, and prevent it from falling off upwards.

[0040] Preferably, the limit block 30 includes a main body block 31 and a protruding block 32 located outside the main body block 31, the protruding block 32 is used to achieve abutment positioning, and second inclined surface structures 311 are provided on both sides of the main body block 31. Specifically, the main body block 31 is located inside the protruding block 32, and the main body block 31 cooperates with the pressing block 42 to slide in the receiving space 110, so that the protruding block 32 protrudes out of the receiving space 110 or retracts into the receiving space 110.

[0041] Preferably, the first inclined surface structure 423 abuts against the second inclined surface structure 311 from outside to inside. When the pressing block 42 is located at the initial position along the height direction, the first inclined surface structure 423 abuts against the second inclined surface structure 311 to prevent the limiting block 30 from escaping from the receiving space 110 outward.

[0042] Specifically, the extension wall 422 is formed into a first inclined surface structure 423 along the transverse inner side surface, and the extension wall 422 is wide at the top and narrow at the bottom. The main body block 31 has an additional wall arranged in cooperation with the extension wall 422, and the additional wall forms a second inclined surface structure 311 along the transverse outer side surface, and the additional wall is narrow at the top and wide at the bottom; the bottom end of the extension wall 422 falls within the vertical range of the second inclined surface structure 311, so the first inclined surface structure 423 always fits inwardly and abuts against the second inclined surface structure 311, otherwise the second inclined surface structure 311 will break away from the restriction of the first inclined surface structure 423 when moving in the transverse direction, resulting in outward separation from the receiving space 110 or the two inclined surface structures are misaligned and can no longer effectively abut.

[0043] Preferably, the limit block 30 is provided with a clamping block 33 on both sides along the front-back direction, and the second inclined surface structure 311 is located above the clamping block 33; the through hole is provided with a clamping groove 111 corresponding to the clamping block 33, and the clamping block 33 is movable in the clamping groove 111 in the horizontal direction and abuts against the wall surface of the clamping groove 111 in the height direction, so that the limit block 30 is guided in the horizontal direction and clamped in the vertical direction.

[0044] Specifically, the elastic member 41 is a spring, one end of which is fixed to the side wall, and the other end is connected to the main body block 31. The elastic member 41 has elastic force after being compressed, so that the limit block 32 can automatically reset outward.

[0045] After the elastic member 41 and the limiting block 30 are pre-assembled, they are installed into the receiving space 110 from the through holes on the side, and the pressing block 42 is assembled into the receiving space 110 from top to bottom, and the process is simple.

[0046] Specifically, refer to Figure 7 As shown, by pressing the pressing portion 421 , the pressing block 42 moves downward, and the first inclined surface structure 423 abuts against the second inclined surface structure 311 obliquely downward, applying a lateral inward force to the second inclined surface structure 311 , so that the limiting block 30 moves inward, and the limiting block 30 compresses the elastic member 41 .

[0047] The pressing portion 421 is released, and the elastic member 41 returns to its original shape and releases the elastic force, causing the limit block 30 to move outward. The second inclined surface structure 311 abuts against the first inclined surface structure 423 obliquely upward, applying a vertical force to the first inclined surface structure 423, causing the pressing block 42 to move outward. Therefore, the limit block 30 and the pressing block 42 are reset.

[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 8As 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 protruding block 32 of the limiting block 30 to achieve installation 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 limiting block 30 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 protruding block 32 includes a second abutment plane 321 and a second guide slope 322. When the protruding block 32 is in a positioning state, the second abutment plane 321 abuts against the first abutment plane 201; the second guide slope 322 abuts upward and slides over the first guide slope 202, so that the limit block 30 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, the elastic member 41 is pre-installed on the limit block 30 so that one end of the elastic member 41 is connected to the inner side of the limit block 30, and then the elastic member 41 and the limit block 30 are pushed into the receiving space 110 together, and the other end of the elastic member 41 is limited to the side wall 11. Next, the pressing block 42 is installed into the receiving space from top to bottom, and has a pressing portion 421 exposed above the side wall 11, and the elastic hook 424 and the guide wall 425 are used for the installed abutment and sliding guidance during movement during installation.

[0055] By pressing the pressing portion 421 by hand, the pressing block 42 can only move vertically downward along the guide groove of the side wall due to the guide wall 425, so that the downward force of the pressing block 42 will be transmitted to the limit block 30 through the inclined structure, and the limit block 30 can only move laterally along the clamping groove 111 due to the clamping block 33. The downward force of the pressing block 42 is converted into a lateral inward force of the limit block 30, causing the limit block 30 to shrink inward.

[0056] At the same time, the limit block 30 will give a compression force to the elastic member 41, and the elastic member 41 will also give a reaction force to the limit block 30; after letting go, the limit block 30 will reset under the reaction force of the elastic member 41, and the pressing part 421 will also reset accordingly.

[0057] 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 322 abuts upward and slides over the first guide slope 202, so that the limit block 30 slides out of the positioning slot 200 for height adjustment.

[0058] However, since the second abutting plane 321 abuts against the first abutting plane 201 in the vertical direction, it cannot be adjusted downward directly. The pressing portion 421 needs to be operated to retract the limit block 30 to the side wall 11 of the rack body 10, and the adjustment component 20 and the positioning groove 200 are released from the abutment and positioning. Then, the rack body 10 can be released, and the rack body 10 moves downward. When a click sound is heard, the rack body 10 is stuck in the positioning groove 200 of the next level, thereby realizing the downward adjustment of the rack body 10. Of course, the rack body 10 can also be adjusted upward by the above method.

[0059] If the shelf body 10 is to be removed from the door body and / or the box body, the pressing portion 421 can only be operated to retract the limit block 30 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.

[0060] The beneficial effects of the present invention are as follows: the rack body 10 can achieve multi-level adjustment in a small range of at least 10 mm; the rack assembly 100 can be removed only by pressing the pressing portion 421 or moving the rack assembly 100 to the top, thereby preventing children from accidentally touching or getting hurt.

[0061] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. 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.
