[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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 an elastic member 41 fixed to the rack body 10 and limited to the second part 32, and a driving member 42 that can drive the second part 32 to move and thereby drive the first part 31 to rotate.

[0033] 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 driving member 42 before the rack body 10 can be removed, which can prevent children from easily removing it and improve safety.

[0034] 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.

[0035] The stopper 30 is fixed to the side wall 11 via the rotating shaft 21, and 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 abuts against the inner wall surface of the receiving space 110. In this way, the rotation adjustment of the stopper 30 is achieved.

[0036] 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, and 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 end of the second part 32 abuts against the inner wall surface of the receiving space 110 and can be driven to rotate by the driving member 42 or abutted and rotated by the elastic member 41, thereby driving the first part 41 to rotate.

[0037] 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 rack body 10 can be adjusted in the vertical height direction, and 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.

[0038] Specifically, the initial state of the stopper 30 is the positioning state, the end of the second part 32 of the stopper 30 abuts against the inner wall of the receiving space 110, and the end of the first part 31 of the stopper 30 abuts against the door body or the box body, maintaining force balance and achieving stable positioning. At the same time, the elastic member 41 and the driving member 42 are both matched with the second part 32.

[0039] Preferably, the elastic member 41 is a metal spring, a protruding wall 111 is provided in the receiving space 110 , one end of the metal spring is inserted into the protruding wall 111 , and the other end of the metal spring is located outside the second portion 32 and pressed against the outer side surface.

[0040] Thus, in the initial state of the limit member 30 , the elastic member 41 can abut against the limit member 30 inwardly to provide an inward pressure; at the same time, after the limit member 30 rotates outwardly, the elastic member 41 is driven to deform outwardly. At this time, the elastic member 41 has elastic force that can provide a restoring force for the limit member 30 .

[0041] Preferably, the driving member 42 is a rectangular sheet structure, which is installed into the receiving space 110 from bottom to top, with one end of the driving member 42 abutting against the inner side of the second part 32 and the other end of the driving member 42 exposed under the side wall 11 for force operation.

[0042] The driving member 42 is operated to move upward, and one end of the driving member 42 drives the second portion 32 of the stopper to rotate outward, driving the positioning protrusion 311 to rotate inward until it is located in the receiving space 110; the driving member 42 is released, and the driving member 42 slides downward, and the second portion 32 of the stopper 30 rotates inward under the action of the metal spring, driving the positioning protrusion 311 to rotate outward to a positioning state. In this way, positioning and height adjustment can be achieved.

[0043] Specifically, the driving member 42 slides upward to abut against the inner side of the second portion 32, gradually separating the second portion 32 of the stopper from the inner wall of the receiving space 110, so that the second portion 32 rotates counterclockwise outward, driving the first portion 31 to rotate counterclockwise inward; conversely, the elastic member 41 provides a restoring force, so that the first portion 31 rotates clockwise outward. The inner side surface of the stopper 30 is inclined, so that one end of the driving member 42 can vertically abut against its inner side surface and drive it to rotate.

[0044] Preferably, the adjustment assembly 20 includes a decorative cover 50 covering the accommodating space 110 , and an abutting protrusion 51 is provided at one end of the decorative cover 50 corresponding to the elastic member 41 , and the abutting protrusion 51 is attached to the outer side surface of the elastic member 41 to prevent it from loosening.

[0045] Reference Figure 7 As shown, the elastic member 41 is deformed outwardly under force, which may easily lead to looseness, affecting the limiting and restoring effect of the elastic member 41 on the limiting member 30; the abutting protrusion 51 further abuts the elastic member 41 inward, so that the elastic member 41 can provide more stable abutting pressure and restoring force.

[0046] Preferably, the driving member 42 is provided with a widened portion 421 , and the decorative cover 50 is provided with a step 52 corresponding to the widened portion 421 , and the widened portion 421 abuts against the step 52 to prevent the driving member 42 from loosening.

[0047] 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.

[0048] 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.

[0049] 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 .

[0050] 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.

[0051] 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.

[0052] The installation process and adjustment process of the rack assembly 100 will be described in detail below, and only the assembly steps of one side of the rack assembly 100 are shown, and the other side is the same.

[0053] First, place the limiting member 30 at the corresponding position of the receiving space 110, and insert the rotating shaft 21 into and fix it on the limiting member 30 and the side wall 11; then, insert one end of the elastic member 41 into the protruding wall 111, and the other end presses against the second part 32 of the limiting member; then, install the driving member 42 into the receiving space 110 from bottom to top, and at this time, you need to hold it with your hands to prevent it from falling; finally, snap the decorative cover 50 onto the side wall of the shelf body 10 to cover the adjusting assembly 20 inside, wherein the abutting protrusion 51 of the decorative cover 50 needs to press the outer side surface of the elastic member 41 to prevent the elastic member 41 from loosening, and the step 52 of the decorative cover 50 cooperates with the widened portion 421 to play a limiting role to prevent the driving member 42 from falling off.

[0054] Reference Figure 7 As shown, the driving member 42 is pressed by hand, and the driving member 42 moves upward; thereby driving the limiting member 30 to rotate around the rotating shaft 21, so that the limiting member 30 protruding from the side wall 11 is retracted into the accommodating space 110. At this time, the positioning protrusion 311 is away from the positioning groove 200, and the shelf body 10 can be adjusted along the height direction; at the same time, the second part 32 of the limiting member 30 rotates outward to apply a force to the metal spring sheet (elastic member 41), so that the metal spring sheet is in a force storage state; on the contrary, if the hand is released, the limiting member 30 will be reset under the force of the metal spring sheet, and the limiting member 30 will also apply a force to the driving member 42 to reset it, and the retracted limiting member 30 will be reset again, protruding from the side wall 11 in a positioning state.

[0055] It is understandable that when the shelf assembly 100 is inserted into the positioning groove 200 of the door body and / or the box body, the shelf assembly 100 can move directly upward. 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 groove 200 for height adjustment.

[0056] 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 member 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 up and down adjustment of the rack body 10.

[0057] If the rack body 10 is to be removed from the door body and / or the box body, the rack assembly 100 can only be removed by pressing the driving member 42 to receive the positioning protrusion 311 inside or sliding the rack body 10 through the uppermost positioning groove 200.

[0058] 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 driving member 42 or moving the shelf assembly 100 to the top, thereby preventing children from accidentally touching or getting hurt.

[0059] 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.
