For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0071] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0072] See also Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a refrigerator having a first direction X, a second direction Z, and a third direction Y which are perpendicular to each other. The first direction X is the width direction of the refrigerator, the second direction Z is the height direction of the refrigerator, and the third direction Y is the depth direction of the refrigerator. The refrigerator includes a box body 10, and the box body 10 is provided with a storage compartment 11, and the storage compartment 11 is used to store items. The storage compartment 11 has a first side wall 111 and a second side wall 112 which are arranged opposite to each other along the first direction X.

[0073] The box body 10 includes a box shell and a box liner. The box liner is arranged in the box shell. A foaming space is formed between the box liner and the box shell. The foaming space is used to install other component structures of the refrigerator and form a foaming insulation layer. The box shell provides protection and support for the box liner. A storage compartment 11 is formed in the box liner. The storage compartment 11 is provided with a take-in and put-out opening to facilitate taking and putting items into the storage compartment 11. A door body is movably connected at the take-in and put-out opening. The door body can be connected to the box shell of the box body 10 in an openable and closable manner. For example, the door body and the box shell can be rotatably connected or slidably connected to open and close the take-in and put-out opening.

[0074] The direction of the access opening of the storage compartment 11 is the front side, the side wall of the storage compartment 11 opposite to the access opening is the rear wall, and the first side wall 111 and the second side wall 112 are respectively arranged on the left and right sides of the storage compartment 11.

[0075] In some embodiments, the refrigerator also includes a refrigeration system (not shown) and an air supply system (not shown), and the refrigeration system and the air supply system are electrically connected to a power supply component, and the power supply component is used to supply electricity to various components of the refrigeration system and the air supply system, thereby ensuring the normal operation of the refrigeration system and the air supply system.

[0076] The refrigeration system is installed in the box shell, and the refrigeration system is used to provide cold air to the storage room 11 inside the box. The refrigeration system generally refers to a closed system composed of components such as a compressor, an evaporator, a condenser, a drying filter, a return air pipe and a throttling device and a refrigerant. Each component is distributed in different positions in the box shell according to its structural characteristics to meet the requirements of its corresponding function. The working process of the refrigeration system mainly includes a compression process, a condensation process, a throttling process and an evaporation process. The compression process is: after the power cord of the refrigerator is plugged in, when the contacts of the thermostat are connected, the compressor starts to work, and the low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor, and is compressed into a high-temperature and high-pressure refrigerant gas by the action of the compressor and then discharged into the condenser. The condensation process is: the high-temperature and high-pressure refrigerant gas exchanges heat with the external environment through the condenser, the temperature drops, and is gradually cooled to a saturated refrigerant vapor at room temperature and high pressure, and then cooled to a saturated refrigerant liquid. The throttling process is: the condensed refrigerant saturated liquid is filtered through a drying filter to remove moisture and impurities and then flows into the throttling device. The throttling device is used to throttle and reduce the pressure, and the refrigerant becomes wet steam at room temperature and low pressure. Evaporation process: The wet steam at room temperature and low pressure enters the evaporator and begins to absorb heat for gasification, which reduces the temperature of the evaporator and its surroundings, realizes refrigeration, and turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor and repeats the above process. The energy conversion is carried out through the state change of the refrigerant, and the heat in the refrigerator is transferred to the air outside the box, thereby realizing the refrigeration cycle of the refrigerator.

[0077] The air supply system is installed in the box shell to provide power for the flow of cold air; the air supply system generally includes a fan and an air supply duct defined in the box shell. In some embodiments, the air inlet end of the air supply duct is arranged close to the fan, and the air outlet end of the air supply duct is arranged away from the fan; in other embodiments, the air outlet end of the air supply duct is arranged close to the fan, and the air inlet end of the air supply duct is arranged away from the fan. The box shell also defines a duct cavity, which is connected to the air supply duct and the storage room 11 inside the box liner, respectively, so that the air supply duct is connected to the storage room 11 through the duct cavity; it should be noted that the box liner is provided with an air outlet, which is used to connect the air duct cavity and the storage room 11. The cold air generated by the refrigeration system enters the air duct cavity through the air supply duct through the operation of the fan, and flows from the air outlet to the storage room 11 to cool the storage room 11. It should also be noted that, in some embodiments, the air outlet is arranged on the side wall on the side opposite to the access opening of the box liner and the storage compartment 11 or on the side adjacent to the access opening of the box liner and the storage compartment 11; it should also be noted that the refrigeration system and the air supply system belong to common knowledge in the field and will not be described in detail here.

[0078] In order to facilitate the classification and storage of items, a storage shelf 20 is provided in the storage compartment 11. Figure 1 - Figure 5 As shown, the storage shelf 20 includes a first plate 21, a second plate 22 and a connecting assembly 23. The first plate 21 has a first end and a second end arranged opposite to each other along a first direction X. The first end of the first plate 21 is connected to the first side wall 111, so that the first side wall 111 can support and fix the first plate 21. It should be noted that the connection between the first plate 21 and the first side wall 111 can be a fixed connection or a detachable connection. When the first plate 21 and the first side wall 111 are detachably connected, the first plate 21 and the first side wall 111 are connected. 11 can be disengaged; the second plate 22 has a first end and a second end arranged oppositely along the first direction X, and the first end of the second plate 22 is detachably connected to the second side wall 112, so that the second side wall 112 can support and fix the second plate 22, and can also make the second plate 22 disengaged from the second side wall 112; the connecting component 23 is connected between the first plate 21 and the second plate 22, and enables the first plate 21 and the second plate 22 to rotate relative to each other; the storage shelf 20 has a first state and a second state through the connecting component 23. When the storage shelf 20 is in the first state, the first plate 21 and the second plate 22 are parallel to each other; when the storage shelf 20 is in the second state, the first plate 21 and the second plate 22 are perpendicular to each other; one of the first plate 21 and the second plate 22 rotates relative to the other, so that the storage shelf 20 switches between the first state and the second state. Among them, in the first state, the height positions of the first plate 21 and the second plate 22 in the second direction Z can be the same or different.

[0079] Among them, when the storage shelf 20 is in the first state, the first plate 21 and the second plate 22 are parallel to each other. In this state, items can be placed on both the first plate 21 and the second plate 22. When the storage shelf 20 is in the second state, the first plate 21 and the second plate 22 are perpendicular to each other. Take the second plate 22 folded downward 90 degrees relative to the first plate 21 as an example for explanation. In this state, the first plate 21 that has not been rotated and folded is set horizontally, and the second plate 22 is rotated and folded and set vertically. Items can be placed normally on the first plate 21; and the item placement space at the position corresponding to the second plate 22 will be increased, which can be used to place higher items.

[0080] Since the first plate 21 and the second plate 22 of the storage shelf 20 of the present application are arranged relatively to each other along the first direction, even if one of the plates is rotated and folded, it will not affect the normal placement of items on the other plate, and the folded plate will not only increase the height of the items that can be placed at the corresponding position, but also will not block the placed items on the unrotated and folded plate when the height of the placed items protrudes beyond the unrotated and folded plate. Therefore, the present application can make full use of the storage space of the storage shelf 20 while increasing the storage height of the storage shelf 20, avoiding the inconvenience of taking items on the storage shelf 20.

[0081] It should be noted that, when the storage shelf 20 is in the second state, the folded plate can be connected to the top wall or the bottom wall of the storage compartment 11 through an additional connecting component.

[0082] In some embodiments, the storage shelf 20 is provided with at least two layers, and at least two layers of storage shelves 20 are arranged in the storage compartment 11 at intervals along the second direction Z. When the upper storage shelf is in the second state, the folded first plate 21 or the second plate 22 abuts against the lower adjacent storage shelf, which can not only increase the height of the items that can be placed at the corresponding position of the lower adjacent storage shelf and the folded plate, but also support the upper storage shelf through the lower adjacent storage shelf, making full use of the space between the upper and lower storage shelves 20 to accommodate the folded plate, reducing the space occupied by the storage shelf 20 in the height direction of the storage compartment 11, and the folded plate can play a role in supporting and fixing the upper storage shelf, and the lower storage shelf 20, the upper folded plate, the upper non-folded plate and the side wall of the storage compartment 11 form a stable support structure, which can ensure the stability of the storage shelf 20 without the need for additional support components.

[0083] See also Figure 7 - Fig.13As shown, in some embodiments, the connection assembly 23 includes a first connection part 231, a second connection part 232 and a mechanical trigger assembly 233, the first connection part 231 is fixed to one of the first plate 21 and the second plate 22; the second connection part 232 is fixed to the other of the first plate 21 and the second plate 22, and the second connection part 232 is rotatably connected to the first connection part 231; the mechanical trigger assembly 233 connects the first connection part 231 and the second connection part 232. The mechanical trigger assembly 233 is used to unlock and lock the connection state between the first connection part 231 and the second connection part 232. When the mechanical trigger assembly 233 is unlocked, the first connection part 231 and the second connection part 232 can rotate relative to each other to switch the state of the storage shelf 20; when the mechanical trigger assembly 233 is locked, the first connection part 231 and the second connection part 232 are parallel to each other, so that the storage shelf 20 is fixed in the first state, or the first connection part 231 and the second connection part 232 are perpendicular to each other, so that the storage shelf 20 is fixed in the second state.

[0084] Taking the first connection part 231 fixed to the first plate 21 and the second connection part 232 fixed to the second plate 22 as an example, the mechanical trigger assembly 233 is operated to change the connection state between the first connection part 231 and the second connection part 232, so that the first connection part 231 and the second connection part 232 can rotate relative to each other or lock each other. For example, by rotating the first connection part 231, the first connection part 231 can drive the first plate 21 to move synchronously, so that the first plate 21 can be freely flipped relative to the second plate 22, and after flipping 90 degrees, the mechanical trigger assembly 233 is operated to lock, so that the storage shelf 20 is switched from the first state to the second state and fixed in the second state. The mechanical trigger assembly 233 is operated again to rotate the first connection part 231 in the opposite direction, drive the first plate 21 to move in the opposite direction, so that the first plate 21 and the second plate 22 can be parallel to each other, and the storage shelf 20 is switched from the second state to the first state and then locked. A mechanical trigger component 233 is used to switch the state of the storage shelf 20. Compared with the electric control structure, the mechanical structure is more stable and reliable. In addition, the mechanical trigger component 233 is connected to the first connecting part 231 and the second connecting part 232, which can avoid operations such as punching holes on the first plate 21 and the second plate 22 to weaken the strength of the plate.

[0085] See also Figure 7 - Fig.13As shown, in some embodiments, the mechanical trigger assembly 233 includes a trigger member 2331, a reset connection member 2332, a locking member 2333 and a limiting member 2334. The trigger member 2331 and the locking member 2333 are respectively installed on the second end of the first connection portion 231. The limiting member 2334 is rotatably installed on the second end of the first connection portion 231, and the limiting member 2334 is fixed to the second end of the second connection portion 232. The limiting member 2334 is provided with a first limiting groove 23341 and a second limiting groove 23342. The first limiting groove 23341 and the second limiting groove 23342 are arranged at intervals along the circumferential direction of the outer peripheral edge of the limiting member 2334. The center angle formed by the center of the first limiting groove 23341 and the center of the second limiting groove 23342 in the circumferential direction of the limiting member 2334 is 90°. The reset connection member 2332 connects the locking member 2333 and the limiting member 2334.

[0086] The trigger member 2331 drives the locking member 2333 to move away from the limiting member 2334, so that the locking member 2333 is separated from the first limiting groove 23341 or the second limiting groove 23342, so that the first connecting portion 231 and the second connecting portion 232 can rotate relatively. The reset connecting member 2332 drives the locking member 2333 to move close to the limiting member 2334, so that the locking member 2333 is clamped into the first limiting groove 23341 or the second limiting groove 23342. The reset connecting member 2332 provides a clamping force for the locking member 2333 to be clamped in the first limiting groove 23341 or the second limiting groove 23342, so that the first connecting portion 231 and the second connecting portion 232 can be relatively locked. By adopting the above structure, the self-locking of the first connection part 231 and the second connection part 232 can be achieved, thereby keeping the first plate 21 and the second plate 22 in the first state or the second state without adding other locking components; the first connection part 231 and the second connection part 232 can also be unlocked, which facilitates the switching of the states of the first plate 21 and the second plate 22.

[0087] The reset connecting member 2332 is a spring, one end of which is fixed to the locking member 2333, and the other end is fixed to the limiting member 2334 through the connecting rod 23343. The limiting member 2334 is rotatably mounted on the first connecting portion 231 through the connecting rod 23343. The limiting member 2334 and the second connecting portion 232 can be integrally formed. The limiting member 2334 includes a first limiting plate and a second limiting plate which are relatively arranged on the second connecting portion 232. The second end of the first connecting portion 231 is inserted into the space between the first limiting plate and the second limiting plate, and mounting holes 2313 are respectively provided on both sides of the second end of the first connecting portion 231. The two ends of the connecting rod 23343 are respectively rotatably assembled on the mounting holes 2313 on both sides of the second end of the first connecting portion 231, and the two ends of the connecting rod 23343 extend out of the first connecting portion 231 and are fixed to the first limiting plate and the second limiting plate. The outer edges of the first and second limiting plates are both provided with first and second limiting grooves 23341 and 23342, and the positions of the first and second limiting grooves 23341 and 23342 on the two limiting plates correspond to each other. The first and second limiting plates are both arc-shaped plates.

[0088] See also Fig. 9 - Fig.11 As shown, in some embodiments, the first connecting portion 231 is provided with a first guide groove 2311 and a second guide groove 2312 along the first direction X. In the first direction X, the second guide groove 2312 is located between the first guide groove 2311 and the second connecting portion 232. The groove length direction of the second guide groove 2312 is extended along the first direction X, and the groove length direction of the first guide groove 2311 is inclined. The height position of one end of the first guide groove 2311 away from the second guide groove 2312 in the second direction Z is higher than the height position of one end of the first guide groove 2311 close to the second guide groove 2312 in the second direction Z. The trigger member 2331 includes a pressing portion 23311, an installation body 23312 and a transmission shaft 23313. The installation body 23312 is rotatably connected to the first connecting portion 231, the pressing portion 23311 is fixedly connected to the installation body 23312, the transmission shaft 23313 is installed on the installation body 23312, and the end of the transmission shaft 23313 is installed on the first guide groove 2311; the locking member 2333 is installed on the installation body 23312, and the end of the locking member 2333 is installed on the second guide groove 2312.

[0089] The pressing portion 23311 is pressed along the second direction Z, and a pressure is applied to the pressing portion 23311 toward the first connection portion 231, so that the pressing portion 23311 moves along the second direction Z. The pressing portion 23311 drives the mounting body 23312 to swing toward the first connection portion 231, so that the transmission shaft 23313 rolls along the first guide groove 2311 away from the limiting member 2334, and drives the locking member 2333 to roll away from the first limiting groove 23341 or the second limiting groove 23342 along the second guide groove 2312 away from the limiting member 2334. The pressing portion 23311 is released, and under the action of the reset connection member 2332, the locking member 2333 is pulled to roll along the second guide groove 2312 toward the limiting member 2334 and is stuck in the first limiting groove 23341 or the second limiting groove 23342 opposite thereto. The first guide groove 2311 and the second guide groove 2312 guide the rolling of the transmission shaft 23313 and the locking member 2333. The first connecting portion 231 and the trigger member 2331 are connected by a rolling assembly method, which can reduce the friction between the two, reduce the operating force on the trigger member 2331, and facilitate the operation.

[0090] The pressing portion 23311 is in the shape of a plate. The installation body 23312 includes a first installation plate and a second installation plate that are arranged opposite to each other, and one end of the pressing portion 23311 extends between the first installation plate and the second installation plate, and is fixedly connected to the first installation plate and the second installation plate.

It should be pointed out that the end portion of the first connecting portion 231 is U-shaped, and the first guide groove 2311 and the second guide groove 2312 are provided on the U-shaped arms on both sides of the first connecting portion 231. The installation body 23312 is inserted into the U-shaped space of the first connecting portion 231.

[0091] See also Figure 4 and Figure 5As shown, in some embodiments, a connecting assembly 23 is provided on each side of the storage shelf 20 along the third direction Y, and the two connecting assemblies 23 have the same structure. An operating rod 24 is connected between the mechanical trigger assemblies 233 of the two connecting assemblies 23. Specifically, the operating rod 24 is connected between the pressing parts 23311 of the two connecting assemblies 23. The two pressing parts 23311 can be operated simultaneously by the operating rod 24, so that the two connecting assemblies 23 can act synchronously, which is convenient for the operation of folding the layer plate. And a connecting assembly 23 is provided on each of the front side and the rear side, which can not only ensure the stability of the connection between the first plate 21 and the second plate 22, but also ensure that a balanced turning force is applied to the first plate 21 and the second plate 22, so that the first plate 21 and the second plate 22 can rotate smoothly.

[0092] See also Figure 1 - Figure 5 As shown, in some embodiments, the storage shelf 20 further includes a reinforcement member 25, which is fixed to the first plate member 21 and the second plate member 22, respectively, and the connection assembly 23 is connected to the reinforcement member 25. The reinforcement member 25 can be coated on the outer peripheral edge of the first plate member 21 and the outer peripheral edge of the second plate member 22. The provision of the reinforcement member 25 can not only enhance the structural strength of the first plate member 21 and the second plate member 22, and ensure the stability of the storage shelf 20, but also provide an installation space for the connection assembly 23, facilitate the assembly of the connection assembly 23, and avoid directly performing operations such as punching holes on the layer plate to reduce the strength of the layer plate.

[0093] See also Figure 1 - Figure 5 As shown, in some embodiments, the first side wall 111 and the second side wall 112 are both provided with an adjustment assembly 30, and the first end of the first plate 21 and the first end of the second plate 22 are respectively mounted on the corresponding adjustment assembly 30, and the adjustment assembly 30 is used to adjust the position of the storage shelf 20 in the second direction Z. When the storage shelf 20 is in the first state, the height position of the storage shelf 20 can be adjusted by the adjustment assembly 30, and then the size of the storage space on the storage shelf 20 is adjusted to match the height of the items to be placed.

[0094] It should be noted that when the upper storage shelf 20 is in the second state, if the height position of the storage shelf 20 needs to be adjusted, the height positions of the upper storage shelf 20 and the lower storage shelf 20 are adjusted synchronously to ensure that the folded layer plate of the upper storage shelf 20 is always in contact with the lower storage shelf 20.

[0095] See also Figure 1 , Fig.14 and Fig.15As shown, in some embodiments, the adjustment component 30 includes a slide groove 311 and a plurality of third limiting grooves 312, the groove length direction of the slide groove 311 extends along the second direction Z, the plurality of third limiting grooves 312 are arranged along the second direction Z (only two third limiting grooves 312 are shown in the figure), the plurality of third limiting grooves 312 are respectively connected to the slide groove 311, and the third limiting grooves 312 extend along the third direction Y; the first end of the first plate 21 and the first end of the second plate 22 are both provided with a plug-in component 211, and the plug-in component 211 is installed in the third limiting groove 312. The plug-in component 211 moves along the third limiting groove 312 to enter or move away from the slide groove 311.

[0096] The connector 211 is supported and fixed by the third limiting groove 312, thereby supporting the first plate 21 and the second plate 22. When adjusting the height position of the storage shelf 20, the storage shelf 20 is manually pushed and pulled in the direction close to the slide groove 311 by external force, so that the connector 211 is separated from the third limiting groove 312 and enters the slide groove 311, so that the storage shelf 20 can slide up and down along the slide groove 311. After the storage shelf 20 is manually adjusted to a suitable height position, the storage shelf 20 is pushed and pulled in the opposite direction, so that the connector 211 of the storage shelf 20 is inserted into the third limiting groove 312 at the corresponding height position, and the height position of the storage shelf 20 is adjusted. The height of the storage shelf 20 is adjusted by the mechanical structure of the slide groove 311 and the third limiting groove 312. The structure is simple, and compared with the electric control lifting structure, the arrangement of electrical components in the box 10 is simplified, and the structure is more stable. In order to prevent the plug-in component 211 from scratching the user when the first plate 21 or the second plate 22 is folded, a protective pad is sleeved on the plug-in component 211. The protective pad is a rubber pad.

[0097] When the storage shelf 20 needs to be switched between the first state and the second state, the storage shelf 20 can be pushed and pulled to allow the connector 211 to disengage from the third limiting groove 312 and enter the sliding groove 311. The sliding groove 311 provides sufficient space for the connector 211 to flip out, thereby facilitating the flipping of the first plate 21 or the second plate 22 and preventing the third limiting groove 312 from blocking the connector 211.

[0098] See also Fig.14 and Fig.15As shown, in some embodiments, the adjustment assembly 30 further includes an installation box 31, a stopper 32 and a driving member 33. The installation box 31 is fixed to the corresponding first side wall 111 or second side wall 112. The installation box 31 is extended along the third direction Y. The installation box 31 has a receiving cavity. The driving member 33 is arranged in the receiving cavity of the installation box 31. The stopper 32 is installed in the receiving cavity of the installation box 31, and the stopper 32 is connected to the driving member 33. The driving member 33 is used to drive the stopper 32 to move close to the slide groove 311 so that the end of the stopper 32 extends into the slide groove 311, or to drive the stopper 32 to move away from the slide groove 311 so that the stopper 32 is separated from the slide groove 311. When the stopper 32 extends into the slide groove 311, the stopper 32 is stopped in the slide groove 311, which can prevent the storage shelf 20 from being unstable due to the plug-in component 211 entering the slide groove 311 due to accidental touching of the push-pull storage shelf 20. When the stopper 32 is disengaged from the slide groove 311, the connector 211 can slide freely along the slide groove 311 under the action of artificial external force. When there are multiple third limiting grooves 312, a corresponding stopper 32 is provided between each two adjacent third limiting grooves 312. Each stopper 32 can be driven by a separate driving member 33, and two stoppers 32 located at the same height position can also be driven by the same driving member 33. In some embodiments, the driving member 33 drives the stopper 32 to reciprocate along the third direction Y, so that the stopper 32 slides along the third direction Y into or out of the slide groove 311. The slide groove 311 and the third limiting groove 312 can be provided on the installation box 31 to facilitate the installation and fixation of the adjustment component 30 as a whole on the first side wall 111 and the second side wall 112.

[0099] See also Fig.14 and Fig.15As shown, both ends of the installation box 31 along the third direction Y are provided with a slide groove 311 and a third limiting groove 312, and each third limiting groove 312 extends toward the same side of the slide groove 311 in the third direction Y. The two slide grooves 311 in the same installation box 31 are provided with corresponding stoppers 32, and the end of the stopper 32 away from the corresponding slide groove 311 is provided with meshing teeth 321; the driving member 33 includes a knob 331 and a transmission gear 332, the knob 331 is fixed to the transmission gear 332, the transmission gear 332 is arranged between the two stoppers 32 in the installation box 31, and the transmission gear 332 is meshed and connected with the two stoppers 32 respectively, and when the transmission gear 332 rotates, the two stoppers 32 are driven to move in opposite directions. The knob 331 is rotated to drive the transmission gear 332 to rotate synchronously, and the transmission gear 332 drives the two stoppers 32 meshing with it to move in the opposite direction, so that the two stoppers 32 are synchronously extended into the corresponding slide grooves 311 or disengaged from the corresponding slide grooves 311, so as to facilitate the synchronous movement of the front and rear sides of the storage shelf 20. The above structure ensures the synchronous blocking and release of the slide grooves 311 on both sides, and the structure is simple and easy to operate. After the knob 331 is rotated, the knob 331 can be kept in the rotation position, thereby ensuring the stable position of the stopper 32. In order to facilitate the rotation operation of the knob 331, the knob 331 partially protrudes from the side of the installation box 31 facing the storage compartment.

[0100] It should be noted that when a plurality of third limiting grooves 312 are correspondingly arranged in a slide groove 311, and a corresponding stopper 32 is arranged between each two adjacent third limiting grooves 312, the transmission gear 332 is meshed and connected with two stoppers 32 located at the same height position. The figure shows that two third limiting grooves 312 are correspondingly arranged in a slide groove 311, and a stopper 32 is arranged between the two third limiting grooves 312.

[0101] The working process of the present invention is:

[0102] When the height position of the entire storage shelf 20 needs to be adjusted, the knob 331 is rotated to disengage the stopper 32 from the slide slot 311, and the storage shelf 20 is pushed and pulled to disengage the connector 211 from the third limiting slot 312 and enter the slide slot 311. The storage shelf 20 is driven to move along the slide slot 311 by artificial external force to adjust the height position of the storage shelf 20. After the storage shelf 20 is adjusted to a suitable height position, the connector 211 is inserted into the third limiting slot 312 at the height position, and the storage shelf 20 is supported by the third limiting slot 312.

[0103] When it is necessary to place higher items in the storage compartment 11, the storage shelf 20 is pushed and pulled by an external force to make the connector 211 enter the slide groove 311; then, the pressing portion 23311 is pressed to make the locking member 2333 disengage from the first limiting groove 23341, and the second plate 22 is manually turned over to make the connector 211 of the second plate 22 disengage from the slide groove 311; after the second plate 22 is turned over 90 degrees, the pressing portion 23311 is released to make the locking member 2333 snap into the second limiting groove 23342 under the action of the reset connector 2332, so that the first connection portion 231 and the second connection portion 232 are locked, and then the first plate 21 and the second plate 22 are kept in a mutually perpendicular state. At this time, higher items can be placed at the position corresponding to the second plate 22 without affecting the taking and placing of items on the first plate 21, which not only makes full use of the space in the storage compartment 11, but also meets the needs of classified storage of items of different heights.

[0104] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
