Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a refrigeration device. Background Art

[0002] Refrigeration equipment such as refrigerators is an appliance that maintains a constant low temperature to store items. As consumers' living standards improve, the requirements for refrigeration equipment are also getting higher and higher.

[0003] Refrigeration equipment, such as refrigerators, typically includes a cabinet, a door, and a door shelf. The cabinet serves as the outer shell of the refrigeration equipment. A refrigeration compartment with a front opening is located within the cabinet for storing items. The door can be located at the front opening of the refrigeration compartment. The door shelf can be located within the refrigeration compartment and on the back side of the door to improve the utilization of the interior space of the refrigeration compartment.

[0004] In existing refrigeration equipment, a door shelf is installed in a refrigeration room in a liftable manner, and the height of the door shelf in the refrigeration room can be adjusted to accommodate items of different heights. However, the lift adjustment structure of the existing door shelf is relatively complex, making it difficult to adjust the door shelf. Utility Model Content

[0005] The purpose of the present utility model is to provide a refrigeration device to optimize the structure of the clothes processing device in the related art and simplify the lifting operation of the shelf.

[0006] The purpose of the present invention is not limited to the above-mentioned purpose, and those skilled in the art can clearly understand other purposes not mentioned through the following description.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] According to one aspect of the present invention, the present invention provides a refrigeration device, which includes: a box body, which is configured as the outer shell of the refrigeration device; a refrigeration compartment with an opening on the front side is provided inside the box body; a door body, which is rotatably provided on the box body, and is used to open or close the refrigeration compartment; a vertically arranged hanging ear is provided on the back side of the door body, and a plurality of card slots are provided on the hanging ear, and the plurality of card slots are arranged at intervals along the vertical direction; a shelf, which is provided on the back side of the door body and slides along the extension direction of the hanging ear; a press-lift module, which is provided on the shelf The push-to-lift module comprises: a locking member, which is rotatably provided on the shelf, and one end of the locking member forms a locking portion; an elastic member, one end of the elastic member is fixedly connected to the shelf, and the other end of the elastic member is against the locking member; a button, which is movably provided on the shelf; the button is transmission-connected with the locking member; wherein, the elastic member can drive the locking member to rotate so that the locking portion extends into the engaging groove and is engaged therein; when the button is pressed, the button drives the locking member to overcome the elastic force of the elastic member and rotate in the opposite direction so that the locking portion is separated from the engaging groove.

[0009] One of the above technical solutions has the following advantages or beneficial effects: when the button is pressed, the button slides under the action of external pressure, and the button can drive the locking member to overcome the elastic force of the elastic member to rotate, thereby driving the locking portion to move away from the clamping groove, so that the locking portion is separated from the clamping groove on the hanging ear, thereby separating the locking member from the hanging ear, and thereby separating the shelf from the hanging ear, so that the shelf can slide up and down relative to the hanging ear, thereby achieving the height adjustment of the shelf. When the button is released, the elastic member can drive the locking member to rotate, which can cause the locking portion to move toward the clamping groove, so that the locking portion rotates and clamps into the clamping groove on the hanging ear, thereby achieving the support of the shelf on the hanging ear. In addition, when the locking member rotates under the action of the elastic member, the locking member can drive the button to move, causing the button to slide in the opposite direction, thereby completing the reset of the button. Thus, the press-to-lift module can be switched between an unlocked state and a locked state by pressing or not pressing the button, thereby improving the convenience of the shelf lifting operation on the door body.

[0010] In some embodiments of the present application, the push-to-lift module also includes a transmission rod, which is rotatably provided on the shelf; the first end of the transmission rod is transmission-connected to the button, and the second end of the transmission rod is rotationally connected to an end of the locking member away from the locking portion; when the button is pressed, the button drives the transmission rod to rotate, and the transmission rod drives the locking member to rotate.

[0011] One of the above technical solutions has the following advantages or beneficial effects: When the button is pressed, the external pressure applied to the button is transmitted to the first end of the transmission rod, causing the transmission rod to rotate within the shelf under the action of the pressure. During the rotation of the transmission rod, the second end of the transmission rod can drive the locking member to rotate away from the engaging slot, thereby separating the locking member from the engaging slot and, in turn, separating the shelf from the mounting lug, allowing the shelf to be adjusted in height. When the button is released, the elastic force of the elastic member drives the locking member to rotate toward the engaging slot. When the locking member rotates toward the engaging slot, the locking member drives the transmission rod to rotate in the opposite direction. When the transmission rod rotates in the opposite direction, the first end of the transmission rod drives the button to slide in the opposite direction, thereby resetting the button. In this way, the transmission rod can better achieve transmission between the button and the locking member, ensuring that the shelf is supported on the door mounting lug and can be raised and lowered.

[0012] In some embodiments of the present application, the button is slidably connected to the top of the shelf, and the top end of the button extends out of the top of the shelf.

[0013] One of the above technical solutions has the following advantages or beneficial effects: the top of the button can extend beyond the top of the shelf, thereby being exposed on the top of the shelf. Thus, the user can directly press down on the top of the button to move the button downward. This makes it easier for the user to apply force, saves effort, and facilitates user operation.

[0014] In some embodiments of the present application, a pressing channel is provided on the shelf, and the pressing channel is arranged vertically; the button is slidably disposed in the pressing channel.

[0015] One of the above technical solutions has the following advantages or beneficial effects: the pressing movement and reset movement of the button are both moved along the pressing channel, so that the pressing channel can limit the button, thereby improving the stability of the button when pressing or resetting.

[0016] In some embodiments of the present application, an adjustment groove is provided at the bottom end of the button; the adjustment groove is horizontally arranged in a direction away from the locking member; an adjustment column is provided at the first end of the transmission rod, and the adjustment column is slidably disposed in the adjustment groove; the transmission rod is transmission-connected to the button through the adjustment column; when the button is pressed downward, the button drives the adjustment column to slide along the adjustment groove in a direction away from the locking member, and drives the transmission rod to rotate.

[0017] One of the above technical solutions has the following advantages or beneficial effects: the adjustment slot is used to limit the sliding movement of the adjustment post on the first end of the transmission rod, so that when the button is pressed, the transmission rod rotates more smoothly. In addition, the extended length of the adjustment slot can limit the rotation range of the transmission rod, and thus limit the rotation range of the locking member, thereby improving the rotational stability of the transmission rod and the locking member.

[0018] In some embodiments of the present application, the transmission rod is arranged below the button, and a guide groove is provided on the transmission rod; the guide groove is arranged upwardly and inclined toward the direction close to the adjustment column; a rotating shaft is provided on the shelf, and the rotating shaft can be movably passed through the guide groove; when the button is pressed downward, the rotating shaft moves along the guide groove relative to the transmission rod, and the transmission rod rotates around the rotating shaft.

[0019] One of the above technical solutions has the following advantages or beneficial effects: the guide groove can be slidably engaged with the rotating shaft member, allowing the rotating shaft member to move relative to the guide groove. Consequently, when the transmission rod rotates relative to the rotating shaft member, the transmission rod can move relative to the rotating shaft member toward or away from the locking member. The guide groove can be used to limit the range of movement of the transmission rod relative to the rotating shaft member, which in turn can be used to limit the range of movement of the transmission rod relative to the locking member. This can further facilitate relative rotation of the transmission rod and the locking member, improving the stability of the transmission connection between the transmission rod and the locking member.

[0020] In some embodiments of the present application, a stop portion is provided on the shelf, and the stop portion is supported on the lower side of the transmission rod; when the button is pressed, the transmission rod abuts against the stop portion, and the stop portion can drive the transmission rod to rotate relative to the rotating shaft.

[0021] One of the above technical solutions has the following advantages or beneficial effects: by utilizing the abutment cooperation between the stop portion and the second end of the transmission rod, the transmission rod can be driven to rotate more smoothly relative to the second rotating shaft.

[0022] In some embodiments of the present application, a first retaining rib is provided on the shelf, and the first retaining rib is provided on one side of the locking member; the elastic member can drive the locking member to rotate toward the first retaining rib; when the locking member rotates to abut against the first retaining rib, the locking portion extends into the retaining groove and is engaged with the retaining groove.

[0023] One of the above technical solutions has the following advantages or beneficial effects: the first retaining rib can be used to limit the rotation of the locking member, thereby preventing the locking portion from rotating too much under the drive of the elastic member, thereby making the rotation of the locking portion more stable.

[0024] In some embodiments of the present application, a second rib is provided on the shelf, and the second rib is provided on a side of the locking member away from the first rib; when the button is pressed, the button can drive the locking member to rotate toward the second rib to separate the locking portion from the snap-in groove.

[0025] One of the above technical solutions has the following advantages or beneficial effects: the second stop rib can be used to limit the rotation of the locking piece, and when the locking piece abuts against the second stop rib, the locking part can be retracted into the shelf and separated from the snap-in groove, thereby ensuring that the shelf can be lifted up and down along the hanging ear.

[0026] In some embodiments of the present application, a limiting channel is provided between the first barrier rib and the second barrier rib, and the locking piece is rotatably provided in the limiting channel; a vertically extending slide groove is provided on the shelf, and the hanging ear is slidably provided in the slide groove; a telescopic opening is provided at one end of the limiting channel close to the slide groove, and the telescopic opening connects the slide groove and the limiting channel; the elastic piece drives the locking piece to rotate toward the direction of the first barrier rib, and the locking part extends into the slide groove from the telescopic opening and engages with the clamping groove; when the button is pressed, the button drives the locking piece to rotate toward the direction of the second barrier rib, and the locking part exits the slide groove from the telescopic opening and is separated from the clamping groove.

[0027] One of the above technical solutions has the following advantages or beneficial effects: the locking member can rotate within the range of the limiting channel, and the limiting channel can be used to limit the rotation angle of the locking member, thereby preventing the locking member from rotating too much and improving the stability of the locking member's rotation. The locking portion can be extended and retracted at the telescopic opening, thereby enabling the locking portion to engage with the engaging groove on the outside of the shelf.

[0051] Figure 1 It is a structural diagram of a refrigeration device provided by an embodiment of the present utility model. Figure 2 yes Figure 1 Schematic diagram of the structure of the middle part. Figure 3 yes Figure 2 Exploded diagram of .

[0052] See also Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the refrigeration device provided by the present invention may include a housing 1. The housing 1 may be a rectangular hollow structure. The interior space of the housing 1 may be used to provide installation space. The housing 1 may be configured as an outer shell of the refrigeration device.

[0053] It should be noted that, in some other embodiments, the box body 1 may also be a hollow structure of other shapes.

[0054] In some embodiments, a refrigeration compartment (not shown) may be provided in the box body 1. The refrigeration compartment may store food.

[0055] In some embodiments, multiple refrigeration compartments may be provided. These compartments may be arranged vertically or horizontally. Each of the compartments may function as an independent storage space, such as a freezer, refrigerator, or temperature-controlled room, to meet different refrigeration requirements for freezing, refrigeration, or temperature-controlled storage, depending on the type of food being stored.

[0056] In some embodiments, a door 2 may be provided on the front side of the cabinet 1. The door 2 may be used to open and close the refrigeration compartment. The door 2 may be connected to the cabinet 1 via a hinge, allowing the door 2 to rotate about the hinge axis to open and close the door 2, thereby opening and closing the corresponding refrigeration compartment.

[0057] It is understandable that multiple door bodies 2 can be provided and arranged in a one-to-one correspondence with the refrigeration compartments. It is also possible that multiple door bodies 2 open and close a refrigeration compartment at the same time.

[0058] In some embodiments, a box liner (not shown) may be provided in the box body 1. A refrigeration compartment may be formed in the box liner.

[0059] It should be noted that a plurality of cooling chambers can be provided. The same cooling chamber can have only one cooling chamber or multiple cooling chambers.

[0060] In some embodiments, the refrigeration device may include a refrigeration assembly (not shown). The refrigeration assembly may be disposed inside the housing 1. The refrigeration assembly is used to provide refrigeration for the interior of the refrigeration device to maintain a low temperature environment in each refrigeration room.

[0061] In some embodiments, the refrigeration assembly may include a compressor (not shown in the figure). The compressor may compress the refrigerant into high-temperature and high-pressure refrigerant vapor.

[0062] In some embodiments, the refrigeration assembly may include a condenser (not shown in the figure) that can condense high-temperature and high-pressure refrigerant vapor into medium-temperature and medium-pressure liquid refrigerant.

[0063] In some embodiments, the condenser assembly may include a throttling device (not shown) that can be used to throttle and depressurize the medium-temperature and medium-pressure liquid refrigerant to convert the medium-temperature and medium-pressure liquid refrigerant into low-temperature and low-pressure refrigerant vapor.

[0064] In some embodiments, the refrigerant assembly may include an evaporator (not shown in the figure). The evaporator can evaporate and boil the low-temperature and low-pressure refrigerant vapor to absorb heat from the surrounding medium.

[0065] In some embodiments, the refrigerant assembly may include refrigeration devices such as a compressor, a condenser, a throttling device, and an evaporator.

[0067] See also Figure 2 、 Figure 3 and Figure 5 As shown, in some embodiments, the refrigeration device may include a shelf 3. The shelf 3 may be disposed on the door 2. A storage slot 31 may be formed in the shelf 3. The storage slot 31 may be used to place food or drinks. The shelf 3 may be disposed on the side wall of the door 2 facing the cabinet 1. The shelf 3 may also be disposed on the back side of the door 2. When the door 2 closes the refrigeration compartment of the cabinet 1, the shelf 3 may be located within the refrigeration compartment, allowing the food or drinks on the shelf 3 to be stored at low temperatures using the cold air within the refrigeration compartment.

[0068] In some embodiments, the shelf 3 can be movably provided on the door body 2. The shelf 3 can be moved up and down on the door body 2, thereby adjusting the height of the shelf 3 so that the storage slots 31 in the shelf 3 can be used to place food or drinks of different heights.

[0069] In some embodiments, multiple shelves 3 may be provided. The multiple shelves 3 may be spaced vertically. The multiple shelves 3 may be movable up and down on the door body 2 . Thus, as the multiple shelves 3 move up and down on the door body 2 , the heights of the multiple shelves 3 on the door body 2 can be adjusted, allowing food or drinks of different heights to be placed on the multiple shelves 3 . Thus, by allowing the multiple shelves 3 to move up and down on the door body 2 , the spacing between adjacent shelves 3 can be adjusted, allowing food or drinks of different heights to be placed between adjacent shelves 3 .

[0070] It should be noted that, in some other embodiments, a plurality of shelves 3 may be arranged on the door body 2 at intervals on the left and right.

[0071] See also Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, the door body 2 may be provided with a hanging ear 22. The hanging ear 22 may be provided on the back side of the door body 2. The hanging ear 22 may be in the shape of an elongated strip. The hanging ear 22 may be provided to extend vertically. The shelf 3 may be slidably connected to the hanging ear 22. The shelf 3 may slide up and down along the extension direction of the hanging ear 22. Thus, the user may control the shelf 3 to slide up and down relative to the hanging ear 22, thereby adjusting the height position of the shelf 3 on the hanging ear 22, and further adjusting the height position of the shelf 3 on the door body 2, thereby being able to place food or drinks of different heights on the shelf 3.

[0072] In some embodiments, two hanging ears 22 may be provided. The two hanging ears 22 may be located on the back side of the door body 2. The shelf 3 may be slidably connected to the two hanging ears 22. Thus, the user can control the shelf 3 to slide up and down relative to the two hanging ears 22, thereby adjusting the height of the shelf 3 on the two hanging ears 22, and further adjusting the height of the shelf 3 on the door body 2, thereby allowing the shelf 3 to be placed at different heights.

[0073] It should be noted that, in some other embodiments, three or more lugs 22 may be provided. The multiple lugs 22 can further improve the stability of the shelf 3 when it is lifted up and down.

[0074] In some embodiments, the ear 22 may be provided with a snap-in groove 221. In this way, when the shelf 3 is provided on the back side of the door body 2, the shelf 3 can be snap-fitted with the snap-in groove 221 on the ear 22, thereby enabling the shelf 3 to be stably supported on the back side of the door body 2.

[0075] In some embodiments, the hanging ear 22 may be provided with a plurality of engaging slots 221. The plurality of engaging slots 221 may be arranged vertically and spaced apart. In this way, when the user controls the shelf 3 to slide up and down relative to the hanging ear 22, the shelf 3 may engage with the engaging slots 221 at different heights, thereby enabling the shelf 3 to be supported at different heights on the hanging ear 22. This allows the shelf 3 to be adjusted to different heights on the hanging ear 22, thereby allowing items of different heights to be placed on the shelf 3.

[0076] In some embodiments, the engaging grooves 221 on the left and right hanging ears 22 can be arranged in a one-to-one correspondence. In this way, the two corresponding engaging grooves 221 on the two hanging ears 22 can support the left and right sides of the shelf 3, thereby making the shelf 3 more stable on the hanging ears 22, preventing the shelf 3 from tilting, and thus preventing the items in the shelf 3 from falling.

[0077] In some embodiments, the plurality of engaging slots 221 may be arranged at equal intervals. Thus, by utilizing the plurality of engaging slots 221 at equal intervals, the height of the shelf 3 can be adjusted up and down at equal intervals.

[0078] It should be noted that, in some embodiments, the plurality of snap-in slots 221 may also be arranged at unequal intervals. In this way, the plurality of snap-in slots 221 at unequal intervals can enable the shelf 3 to be fixed at different specific heights of the hanging ear 22 to place items of various heights.

[0079] It should be noted that, in some embodiments, the engaging groove 221 may be recessed on only one of the hanging ears 22. Thus, the engaging groove 221 may not be provided on the other hanging ear 22, thereby reducing the cost of the hanging ear 22 while ensuring that the shelf 3 can be supported.

[0080] See also Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, a support rib 21 may be provided on the back side of the door body 2. The support rib 21 may be protruding from the back side of the door body 2. The support rib 21 may be arranged to extend vertically. Two support ribs 21 may be provided. The two support ribs 21 may be spaced apart from each other. The shelf 3 may be movably disposed between the two support ribs 21. Thus, the two support ribs 21 can be used to limit the left and right positions of the shelf 3, thereby improving the stability of the shelf 3 between the two support ribs 21, and thus improving the stability of the shelf 3 on the door body 2.

[0081] In some embodiments, the lugs 22 may be provided on the support ribs 21. The lugs 22 may be provided on the sidewalls of the support ribs 21 facing the other support ribs 21. The shelf 3 may be slidably provided on the support ribs 21 via the lugs 22, thereby enabling the shelf 3 to slide up and down along the extension direction of the support ribs 21, thereby adjusting the height of the shelf 3 on the support ribs 21, and further adjusting the height of the shelf 3 on the door 2.

[0082] It should be noted that, in some other embodiments, the hanging ear 22 may not be provided on the supporting rib 21 , but may be directly provided on the back wall of the door body 2 .

[0083] In some embodiments, when two lugs 22 are provided, one lug 22 can be provided on one of the support ribs 21. The other lug 22 can be provided on the other support rib 21. The two lugs 22 can be provided on the opposite side walls of the two support ribs 21. In this way, the two support ribs 21 can be used to limit the left and right positions of the shelf 3. At the same time, the shelf 3 can slide up and down relative to the two lugs 22, allowing the shelf 3 to slide up and down relative to the two support ribs 21. The two support ribs 21 can then limit the left and right positions of the shelf 3, allowing the shelf 3 to slide up and down more stably between the two support ribs 21.

[0084] It should be noted that, in some other embodiments, when two hanging ears 22 are provided, one of the hanging ears 22 may be provided on the support rib 21. The other hanging ear 22 may not be provided on the support rib 21, but may be provided in other areas on the back side of the door body 2.

[0085] It should also be noted that, in other embodiments, when two hanging ears 22 are provided, both hanging ears 22 may not be provided on the supporting rib 21 , but may be provided in other areas on the back side of the door body 2 .

[0086] See also Figure 5 As shown, in some embodiments, the shelf 3 may be provided with a slide groove 32. The slide groove 32 may be provided on the outer side wall of the shelf 3. The slide groove 32 may be provided to extend vertically. The lug 22 may be slidably provided in the slide groove 32. The shelf 3 may slide up and down relative to the lug 22 to adjust the height of the shelf 3 on the door body 2, thereby enabling items of different heights and sizes to be placed in the shelf 3. In addition, the slide groove 32 and the lug 22 may be used to limit the sliding of the shelf 3, thereby improving the stability of the shelf 3 when it is raised and lowered.

[0087] In some embodiments, two slide grooves 32 may be provided. The two slide grooves 32 may be respectively provided on two opposite side walls of the shelf 3. The two lugs 22 are slidably provided in the slide grooves 32. Thus, by limiting the sliding position of the two lugs 22, the left and right sides of the shelf 3 can slide up and down synchronously along the two lugs 22, thereby further improving the stability of the shelf 3 when it is raised or lowered.

[0088] It should be noted that, in some other embodiments, there may be three or more chute slots 32 , and the number of chute slots 32 may correspond to the number of lugs 22 .

[0090] 6 , in some embodiments, the refrigeration device may include a push-lift module 4. The push-lift module 4 may be provided on the shelf 3. The push-lift module 4 may be configured to engage with or disengage from the engaging slot 221 of the hanging ear 22.

[0091] When the push-to-lift module 4 is engaged with the engaging groove 221 on the hanging ear 22, the push-to-lift module 4 can be engaged with the hanging ear 22, so that the push-to-lift module 4 can be supported on the hanging ear 22, so that the push-to-lift module 4 can be supported on the back side of the door body 2, and so that the shelf 3 can be supported on the back side of the door body 2.

[0092] When the push-to-lift module 4 is separated from the snap-in slot 221 on the hanging ear 22, the push-to-lift module 4 can be separated from the hanging ear 22, so that the push-to-lift module 4 can slide up and down relative to the hanging ear 22, and the shelf 3 can slide up and down relative to the hanging ear 22, so that the height position of the shelf 3 on the hanging ear 22 can be adjusted, and the height position of the shelf 3 on the door body 2 can be adjusted, so that items of different heights and sizes can be placed in the shelf 3.

[0093] In some embodiments, the press-lift module 4 has a locked state and an unlocked state, and the locked state and the unlocked state can be switched to each other.

[0094] When the user does not need to adjust the height of the shelf 3 on the door body 2, the push-lift module 4 can be in a locked state. At this time, the push-lift module 4 can be engaged with the engaging groove 221 on the hanging ear 22, thereby enabling the shelf 3 to be supported on the back side of the door body 2.

[0095] When the user needs to adjust the height of the shelf 3 on the door 2, the push-lift module 4 can be switched from the locked state to the unlocked state. At this time, the push-lift module 4 can be separated from the engaging groove 221 on the hanging ear 22, thereby allowing the shelf 3 to slide up and down along the hanging ear 22 through the slide groove 32, thereby adjusting the height position of the shelf 3 on the door 2, so that items of different heights and sizes can be placed on the shelf 3.

[0096] In some embodiments, two push-to-lift modules 4 can be provided. The two push-to-lift modules 4 can be located on opposite sides of the shelf 3. Thus, one push-to-lift module 4 can be engaged with or separated from the engaging slot 221 on one hanging ear 22, and the other push-to-lift module 4 can be engaged with or separated from the engaging slot 221 on the other hanging ear 22.

[0097] When the two push-lift modules 4 are simultaneously supported on the two corresponding snap-in slots 221 of the two hanging ears 22, the opposite sides of the shelf 3 can be fixed on the two hanging ears 22 at the same time, thereby improving the stability of the shelf 3 supported on the door body 2.

[0098] When the two press-lift modules 4 are separated from the two corresponding snap-in grooves 221 on the two hanging ears 22 at the same time, the opposite sides of the shelf 3 can be separated from the two hanging ears 22 at the same time, so that the shelf 3 can slide up and down relative to the two hanging ears 22, thereby adjusting the height position of the shelf 3 on the hanging ears 22, and then adjusting the height position of the shelf 3 on the door body 2.

[0099] It should be noted that, in some other embodiments, three or more pressing and lifting modules 4 may be provided. The number of pressing and lifting modules 4 may correspond to the number of hanging ears 22 .

Figure 10 yes Figure 9 Schematic diagram of the structure of the middle part. Figure 11 yes Figure 10 Schematic diagram of the structure from another perspective. Figure 12 yes Figure 9 Schematic diagram of the structure of the middle part.

[0101] See also Figure 8 、 Figure 9 and Figure 12 As shown, in some embodiments, the press-lift module 4 may include a locking member 41. The locking member 41 may be rotatably disposed on the shelf 3. One end of the locking member 41 may form a locking portion 413.

[0102] When the locking member 41 rotates toward the first direction, the locking portion 413 rotates toward the first direction, and the locking portion 413 can move toward the direction close to the hanging ear 22, so that the locking portion 413 can be engaged with the engaging groove 221 on the hanging ear 22, thereby enabling the pressing and lifting module 4 to be engaged with the engaging groove 221 on the hanging ear 22, thereby enabling the shelf 3 to be supported on the hanging ear 22 through the pressing and lifting module 4.

[0103] When the locking piece 41 rotates in the opposite direction to the first direction, the locking portion 413 rotates in the opposite direction to the first direction, and the locking portion 413 can move in the direction away from the hanging ear 22, so that the locking portion 413 can be separated from the clamping groove 221 on the hanging ear 22, thereby separating the pressing and lifting module 4 from the clamping groove 221 on the hanging ear 22, so that the shelf 3 can slide up and down relative to the hanging ear 22, and thus the shelf 3 can be adjusted to a height position on the hanging ear 22, so that items of different heights can be placed in the shelf 3.

[0104] In some embodiments, the locking member 41 is rotatably disposed on one side of the chute 32. Thus, when the locking member 41 is rotated in a first direction, the locking portion 413 rotates in the first direction, and the locking portion 413 can extend into the chute 32 and engage with the engaging groove 221 on the hanging ear 22, thereby supporting the push-lift module 4 on the hanging ear 22, and further enabling the shelf 3 to be stably supported on the hanging ear 22. When the locking member 41 is rotated in the opposite direction from the first direction, the locking portion 413 rotates in the opposite direction from the first direction, and the locking portion 413 can exit the chute 32 and separate from the engaging groove 221 on the hanging ear 22, thereby enabling the shelf 3 to slide up and down relative to the hanging ear 22, thereby enabling the shelf 3 to adjust its height on the hanging ear 22, thereby allowing items of different heights to be placed on the shelf 3.

[0105] Please refer to Figure 10 and Figure 11 As shown, in some embodiments, the shelf 3 may be provided with a first rotating shaft 42. The locking member 41 can rotate relative to the first rotating shaft 42. When the locking member 41 rotates in a first direction, the locking portion 413 can rotate about the first rotating shaft 42 in the first direction. When the locking member 41 rotates in the opposite direction from the first direction, the locking portion 413 can rotate in the opposite direction from the first direction. Thus, the locking member 41 can rotate more stably on the shelf 3 by rotating relative to the first rotating shaft 42, thereby improving the stability of the locking member 41 during rotation.

[0106] In some embodiments, the first rotating shaft 42 can be integrally formed on the shelf 3 . The locking member 41 is rotatably sleeved on the first rotating shaft 42 .

[0107] It should be noted that, in other embodiments, the first rotating shaft 42 may be provided separately from the shelf 3. The first rotating shaft 42 may rotate relative to the shelf 3. The locking member 41 may be fixed to the first rotating shaft 42. The locking member 41 may be rotatably provided on the shelf 3 via the first rotating shaft 42.

[0108] See also Figure 6 、 Figure 8 and Figure 12 As shown, in some embodiments, the push-lift module 4 may include an elastic member 43. The elastic member 43 may be provided on the shelf 3. One end of the elastic member 43 may be fixedly connected to the shelf 3, and the other end of the elastic member 43 may be against the locking member 41. The elastic member 43 may drive the locking member 41 to rotate in the first direction by its own elastic force, so that the locking member 41 extends into the engaging groove 221 engaged with the hanging ear 22. Thus, the elastic member 43 can be used to support the locking member 41 on the hanging ear 22, so that the push-lift module 4 is in a locked state, thereby enabling the shelf 3 to be supported on the hanging ear 22, and thereby enabling the shelf 3 to be supported on the door body 2.

[0109] In some embodiments, the elastic member 43 may be a torsion spring. The torsion spring may be wound around the first rotating shaft member 42. One end of the torsion spring may be fixedly connected to the shelf 3, and the other end of the torsion spring may abut against the locking member 41. The torsion spring may drive the locking member 41 to rotate in the first direction through its own elastic force, so that the locking member 41 extends into the engaging groove 221 engaged with the hanging ear 22. Thus, the torsion force of the torsion spring can be used to rotate the locking member 41 in the first direction, so that the locking member 41 is supported on the hanging ear 22, thereby locking the press-lift module 4.

[0110] It should be noted that, in some other embodiments, the elastic member 43 may be a spring or other elastic members 43 .

[0111] Figure 13 yes Figure 8 Schematic diagram of the structure in another state. Figure 14 yes Figure 2 sectional view of . Figure 15 yes Figure 14 Enlarged view of part A. Figure 16 yes Figure 15 Schematic diagram of the structure in another state.

[0112] See also Figure 7 、 Figure 8 、 Figure 9 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 15 as well as Figure 16As shown, in some embodiments, the pressure adjustment module may include a button 45. The button 45 is movably provided on the shelf 3. The button 45 can be in transmission connection with the locking member 41.

[0113] When the button 45 is pressed, the button 45 slides under the action of external pressure, and the button 45 can drive the locking member 41 to overcome the elastic force of the elastic member 43 and rotate in the second direction. The second direction can be opposite to the first direction, and thus can drive the locking portion 413 to move in the direction away from the snap-in groove 221, so that the locking portion 413 is separated from the snap-in groove 221 on the hook 22, and thus the locking member 41 is separated from the hook 22, and thus the shelf 3 is separated from the hook 22, so that the shelf 3 can slide up and down relative to the hook 22, thereby realizing the height position adjustment of the shelf 3.

[0114] When the button 45 is released, the elastic force of the elastic member 43 causes the locking member 41 to rotate in the first direction, causing the locking portion 413 to move toward the engaging groove 221. This allows the locking portion 413 to rotate and engage with the engaging groove 221 on the hanging ear 22, thereby supporting the shelf 3 on the hanging ear 22. Furthermore, when the locking member 41 rotates in the first direction, the locking member 41 can drive the button 45 to move, causing the button 45 to slide in the opposite direction, thereby completing the reset of the button 45.

[0115] Thus, the button 45 can be pressed or not pressed (i.e., the button is released) to switch the press-to-lift module 4 between the unlocked state and the locked state, thereby improving the convenience of the lifting operation of the shelf 3 on the door body 2.

[0116] See also Figure 10 As shown, in some embodiments, a pressing channel 342 may be opened on the shelf 3. The button 45 is slidably arranged in the pressing channel 342. One end of the button 45 can extend into the pressing channel 342, and the other end of the button 45 can be exposed on the shelf 3.

[0117] Thus, the user can press the button 45 to expose the part of the shelf 3 and drive the button 45 to slide in the pressing channel 342. During the sliding process, the button 45 can drive the locking member 41 to rotate in the opposite direction of the first direction under the action of external pressure, so that the locking part 413 can be separated from the snap-fit ​​groove 221, thereby enabling the shelf 3 to be separated from the snap-fit ​​groove 221 on the hook 22, and thereby enabling the shelf 3 to be raised and lowered.

[0118] When the user releases the button 45, the elastic member 43 can drive the locking member 41 to rotate in the first direction, so that the locking portion 413 is engaged with the engaging groove 221, and can drive the button 45 to slide back along the pressing channel 342 to reset, so that part of the button 45 is exposed to the shelf 3 again, so that it can be pressed again. In this way, the button 45 moves along the pressing channel 342 during both pressing and reset, so that the pressing channel 342 can limit the button 45, thereby improving the stability of the button 45 when pressing or reset.

[0119] In some embodiments, the pressing channel 342 can be arranged vertically. The button 45 can move vertically along the pressing channel 342. The user can apply a pushing force toward the pressing channel 342 toward the portion of the button 45 that exposes the shelf 3, thereby pushing the button 45 to slide along the pressing channel 342, and then driving the locking member 41 to rotate in the opposite direction in the first direction through the button 45, thereby separating the locking portion 413 from the clamping groove 221, thereby separating the shelf 3 from the hanging ear 22, and thereby adjusting the height position of the shelf 3. In this way, with the pressing channel 342 arranged vertically, the user only needs to press the button 45 vertically to adjust the height of the shelf 3 on the hanging ear 22. The vertical pressing operation facilitates the user to exert force, making the lifting and lowering operation of the shelf 3 more convenient.

[0120] It should be noted that, in some other embodiments, the button 45 can be directly provided on the outer wall of the shelf 3 .

[0121] In some embodiments, the button 45 can be located on the top of the shelf 3. The top of the button 45 can extend beyond the top of the shelf 3 and be exposed on the top of the shelf 3. Thus, the user can directly press down on the top of the button 45 to move the button 45 downward. This makes it easier for the user to apply force, saves effort, and facilitates user operation.

[0122] It should be noted that, in some other embodiments, the button 45 may be provided on the side of the shelf 3. One end of the button 45 may be exposed on the side of the shelf 3.

[0123] It should also be noted that, in other embodiments, the button 45 may be provided at the bottom of the shelf 3. The bottom end of the button 45 may be exposed from the bottom of the shelf 3.

[0124] See also Figure 8 、 Figure 9 、 Figure 12 、 Figure 15 and Figure 16As shown, in some embodiments, the pressure adjustment module may include a transmission rod 44. The transmission rod 44 is rotatably disposed on the shelf 3. The transmission rod 44 may be disposed between the locking member 41 and the button 45. A first end of the transmission rod 44 may be in transmission connection with the button 45. A second end of the transmission rod may be in transmission connection with the locking member 41.

[0125] When the button 45 is pressed, the external pressure applied to the button 45 is transmitted to the first end of the transmission rod 44, causing the transmission rod 44 to rotate within the shelf 3 under the action of the pressure. During the rotation of the transmission rod 44, the second end of the transmission rod 44 can drive the locking member 41 to rotate in the second direction, thereby separating the locking member 41 from the engaging groove 221, thereby separating the shelf 3 from the hanging ear 22, and allowing the shelf 3 to be adjusted in height.

[0126] When the button 45 is released, the elastic force of the elastic member 43 drives the locking member 41 to rotate in the first direction. As the locking member 41 rotates in the first direction, the locking member 41 drives the transmission rod 44 to rotate in the opposite direction. As the transmission rod 44 rotates in the opposite direction, the first end of the transmission rod 44 drives the button 45 to slide in the opposite direction, thereby resetting the button 45.

[0127] In this way, the transmission rod 44 can better realize the transmission between the button 45 and the locking member 41 to ensure that the support and lifting and lowering adjustment operations of the shelf 3 on the hanging ear 22 of the door body 2 are completed.

[0128] See also Figure 8 、 Figure 9 and Figure 13 As shown, in some embodiments, the bottom end of the button 45 may be provided with an adjustment slot 451. The adjustment slot 451 may be elongated and arranged horizontally, facing away from the locking member 41. The first end of the transmission rod 44 may be provided with an adjustment post 443. The adjustment post 443 is slidably disposed within the adjustment slot 451. The transmission rod 44 and the button 45 are in transmission connection via the adjustment post 443 and the adjustment slot 451.

[0129] When the button 45 is pressed downward, the button 45 moves downward under the action of external pressure, squeezing the adjustment post 443 within the adjustment slot 451. This allows the adjustment post 443 to move along the adjustment slot 451 away from the locking member 41, thereby driving the first end of the transmission rod 44 to move downward. As the first end of the transmission rod 44 moves downward, the transmission rod 44 can rotate and drive the locking member 41 to rotate in the second direction, causing the locking portion 413 to rotate away from the engaging slot 221, thereby separating the locking portion 413 from the engaging slot 221.

[0130] When the button 45 is released, the elastic force of the elastic member 43 drives the transmission rod 44 to rotate in the opposite direction. When the transmission rod 44 rotates in the opposite direction, the first end of the transmission rod 44 can move upward, so that the adjustment post 443 moves upward, and then the adjustment post 443 can move along the adjustment slot 451 toward the locking member 41.

[0131] Thus, the adjustment slot 451 is used to limit the sliding movement of the adjustment post 443 on the first end of the transmission rod 44, so that when the button 45 is pressed, the transmission rod 44 can rotate more smoothly. In addition, the extended length of the adjustment slot 451 can limit the rotation range of the transmission rod 44, and thus limit the rotation range of the locking member 41, thereby improving the rotational stability of the transmission rod 44 and the locking member 41.

[0132] It should be noted that, in some other embodiments, the adjustment slot 451 may also be arranged to be inclined upward or downward.

[0133] See also Figure 12 As shown, in some embodiments, the bottom of the button 45 may be provided with two oppositely disposed ears 452. The adjustment slot 451 may be provided on one ear 452. The first end of the transmission rod 44 may extend between the two ears 452. The adjustment column 443 on the transmission rod 44 may extend into the adjustment slot 451 and may slide along the adjustment slot 451 between the two ears 452. Thus, by utilizing the two ears 452 to limit the sliding movement of the adjustment column 443 at the first end of the transmission rod 44, the sliding stability of the adjustment column 443 between the two ears 452 can be improved, thereby improving the sliding stability of the adjustment column 443 in the adjustment slot 451 on the ear 452.

[0134] In some embodiments, there may be two adjustment slots 451. The two adjustment slots 451 may be respectively opened on the two support ears 452. The two adjustment slots 451 may be arranged opposite to each other. At this time, the first end of the transmission rod 44 may extend between the two support ears 452. There may be two adjustment columns 443 on the transmission rod 44. The two adjustment columns 443 may be respectively arranged on opposite sides of the transmission rod 44. One adjustment column 443 may extend into one adjustment slot 451 and slide. The other adjustment column 443 may extend into the other adjustment slot 451 and slide. Thus, the two support ears 452 can be used to respectively limit the sliding of the two adjustment columns 443 at the first end of the transmission rod 44, thereby improving the sliding stability of the adjustment column 443 in the adjustment slot 451.

[0135] See also Figure 8 、 Figure 9 、 Figure 13 、 Figure 15 as well as Figure 16As shown, in some embodiments, the transmission rod 44 may be provided with a guide slot 444. The guide slot 444 may be located below the button 45. The transmission rod 44 may be located below the button. The guide slot 444 may be arranged to be tilted upward toward the adjustment column 443. The shelf 3 may be provided with a second rotating shaft 46. The second rotating shaft 46 may be provided on the mounting box 34. The second rotating shaft 46 may be movably inserted into the guide slot 444.

[0136] When the button 45 is pressed downward, the second rotating shaft 46 can move relative to the transmission rod 44 along the guide groove 444 , and the transmission rod 44 can rotate around the second rotating shaft 46 .

[0137] Specifically, when the button 45 is pressed downward, the button 45 can drive the first end of the transmission rod 44 to move downward. As the first end of the transmission rod 44 moves downward, the transmission rod 44 can rotate about the second rotating shaft 46, causing the second rotating shaft 46 to move relatively along the guide groove 444 toward the adjustment column 443, so that the second end of the transmission rod 44 can move toward the direction of squeezing the locking member 41, thereby driving the locking member 41 to rotate about the first rotating shaft 42 in the second direction, thereby rotating and separating the locking portion 413 from the engaging groove 221.

[0138] When the button 45 is released, the elastic force of the elastic member 43 drives the locking member 41 to rotate the transmission rod 44 in the opposite direction. When the transmission rod 44 rotates in the opposite direction, the second end of the transmission rod 44 can move away from the locking member 41, and the first end of the transmission rod 44 can move upward, thereby causing the second rotating shaft 46 to move relatively along the guide groove 444 in a direction away from the adjustment post 443.

[0139] Thus, the guide groove 444 can be slidably engaged with the second rotating shaft member 46, allowing the second rotating shaft member 46 to move relative to the guide groove 444. Consequently, when the transmission rod 44 rotates relative to the second rotating shaft member 46, the transmission rod 44 can move relative to the second rotating shaft member 46 to move closer to or away from the locking member 41. The guide groove 444 can be used to limit the range of movement of the transmission rod 44 relative to the second rotating shaft member 46, and further limit the range of movement of the transmission rod 44 relative to the locking member 41. This can make the relative rotation of the transmission rod 44 and the locking member 41 smoother, thereby improving the stability of the transmission connection between the transmission rod 44 and the locking member 41.

[0140] See also Figure 8 、 Figure 11 、 Figure 13 、 Figure 15 and Figure 16 As shown, in some embodiments, a stopper 35 may be provided on the shelf 3. The stopper 35 may be supported on the lower side of the transmission rod 44.

[0141] When the button 45 is pressed downward, the button 45 drives the first end of the transmission rod 44 to move downward and rotate about the second rotating shaft 46. The lower side of the second end of the transmission rod 44 can abut against the stopper 35. Therefore, the stopper 35 can ensure that when the transmission rod 44 slides relative to the second rotating shaft 46, the second end of the transmission rod 44 can rotate smoothly relative to the second rotating shaft 46, and prevent the second end of the transmission rod 44 from moving downward under the drive of the knob 45, so that the locking member 41 can rotate smoothly in the second direction, thereby improving the stability of the rotation of the transmission rod 44 on the shelf 3.

[0142] When the button 45 is released, the elastic force of the elastic member 43 drives the locking member 41 to rotate in the first direction. As the locking member 41 rotates in the first direction, the second end of the transmission rod 44 rotates downward relative to the second rotating shaft 46, and the first end of the transmission rod 44 moves upward until the lower side of the second end of the transmission rod 44 abuts against the stopper 35. At this point, the first end of the transmission rod 44 can reset the button 45.

[0143] In this way, the stopper 35 abuts against the second end of the transmission rod 44 , so that the transmission rod 44 can be driven to rotate in the forward or reverse direction relative to the second rotating shaft 46 more smoothly.

[0144] See also Figure 10 、 Figure 11 and Figure 16 As shown, in some embodiments, a third rotating shaft 47 is provided between the second end of the transmission rod 44 and the end of the locking member 41 away from the locking portion 413. The third rotating shaft 47 is movably disposed within the shelf 3. The second end of the transmission rod 44 is rotatably disposed on the third rotating shaft 47. The end of the locking member 41 away from the locking portion 413 is rotatably disposed on the third rotating shaft 47.

[0145] When the button 45 is pressed downward, the transmission rod 44 can rotate relative to the second rotating shaft 46 under the action of external pressure. When the transmission rod 44 rotates, the second end of the transmission rod 44 can drive the third rotating shaft 47 to move upward. The third rotating shaft 47 drives the end of the locking member 41 away from the locking portion 413 to rotate in the second direction, thereby separating the locking portion 413 from the engaging groove 221, thereby achieving the height adjustment of the shelf 3.

[0146] When the button 45 is released, the elasticity of the elastic member 43 can drive the locking member 41 to rotate in the first direction, so that the locking member 41 moves downward away from one end of the locking portion 413, thereby causing the third rotating shaft member 47 to move downward, and then driving the transmission rod 44 to rotate in the opposite direction through the third rotating shaft member 47.

[0147] Therefore, the third rotating shaft 47 can make the transmission between the locking member 41 and the transmission rod 44 smoother.

[0148] See also Figure 10 、 Figure 11 and Figure 16 As shown, in some embodiments, the button 45 drives the first end of the transmission rod 44 to rotate downward around the second rotating shaft 46, and causes the second end of the transmission rod 44 caused by the second rotating shaft 46 to rotate upward relative to the second rotating shaft 46, thereby driving the third rotating shaft 47 to move upward, and the third rotating shaft 47 drives the locking member 41 to rotate around the first rotating shaft 42, thereby realizing that the locking portion 413 on the locking member 41 is rotated and separated from the snap-fit ​​groove 221 and retracted into the shelf 3, thereby enabling the shelf 3 to be lifted up and down along the hanging ear 22.

[0149] See also Figure 10 、 Figure 11 as well as Figure 13 As shown, in some embodiments, a movable slot 343 is defined on the shelf 3. The movable slot 343 can be arranged circumferentially with the first rotating shaft 42 as the center. The third rotating shaft 47 is movably disposed within the movable slot 343. When the button 45 is pressed downward, the button 45 drives the first end of the transmission rod 44 to rotate downward relative to the second rotating shaft 46, causing the second end of the transmission rod 44 to rotate upward relative to the second rotating shaft 46, thereby driving the third rotating shaft 47 to move upward along the movable slot 343, causing the locking member 41 to rotate about the first rotating shaft 42. This causes the locking portion 413 on the locking member 41 to rotate and separate from the engaging slot 221, thereby first separating the shelf 3 from the hanging ear 22, allowing the shelf 3 to be raised and lowered along the hanging ear 22. Thus, the movable slot 343 can limit the rotation of the locking member 41, thereby improving the stability of the locking member 41 during rotation. At the same time, the movable groove 343 can be used to enable the locking member 41 to accurately rotate around the first rotating shaft 42, thereby improving the accuracy of the rotation of the locking member 41.

[0150] See also Figure 8 、 Figure 9 、 Figure 13 、 Figure 15 as well as Figure 16As shown, in some embodiments, the locking member 41 may include a first connecting arm 411 and a second connecting arm 412. The locking member 41 may be formed by the first connecting arm 411 and the second connecting arm 412 connected at an angle. The locking portion 413 may be an end of the first connecting arm 411 away from the second connecting arm 412. The first rotating shaft 42 may be provided with a connection between the first connecting arm 411 and the second connecting arm 412. The first connecting arm 411 and the second connecting arm 412 may rotate synchronously about the first rotating shaft 42. When the button 45 drives the second connecting arm 412 to rotate via the transmission rod 44, the first connecting arm 411 may also drive the first connecting arm 411 to rotate synchronously. In this way, by utilizing the angle connection between the first connecting arm 411 and the second connecting arm 412, the second connecting arm 412 can be bent and extended toward the direction of the transmission rod 44, so that the transmission rod 44 only needs a smaller rotation angle to drive the locking portion 413 on the first connecting arm 411 to extend into the snap-in groove 221, that is, the rotation range of the transmission rod 44 and the locking member 41 can be reduced, and the structure of the transmission rod 44 and the locking member 41 can be simplified, making the structure of the transmission rod 44 and the locking member 41 more reasonable.

[0151] It should be noted that the angle between the first connecting arm 411 and the second connecting arm 412 can be adjusted according to actual needs.

[0152] In some embodiments, the first connecting arm 411 and the second connecting arm 412 may be integrally formed.

[0153] It should be noted that, in some other embodiments, the locking member 41 may be formed by connecting a first connecting arm 411 and a second connecting arm 412 that are separate parts.

[0154] See also Figure 8 、 Figure 9 、 Figure 13 、 Figure 15 as well as Figure 16 As shown, in some embodiments, the transmission rod 44 may include a third connecting arm 441 and a fourth connecting arm 442. The third connecting arm 441 and the fourth connecting arm 442 are connected. The end of the third connecting arm 441 away from the fourth connecting arm 442 may serve as the second end of the transmission rod 44. The end of the third connecting arm 441 away from the fourth connecting arm 442 may be in transmission connection with the locking member 41. The end of the fourth connecting arm 442 away from the third connecting arm 441 may be in transmission connection with the button 45. The movement of the third connecting arm 441 away from the fourth connecting arm 442 enables the knob to drive the locking member 41 to rotate.

[0155] In this way, by utilizing the angle connection between the third connecting arm 441 and the fourth connecting arm 442, the fourth connecting arm 442 can be bent and extended toward the direction of the button 45. The button 45 only needs to move a short distance to drive the fourth connecting arm 442 and the third connecting arm 441 to rotate synchronously, that is, the moving range of the button 45 can be reduced, and the structure of the button 45 and the transmission rod 44 can be simplified, making the structure of the button 45 and the transmission rod 44 more reasonable.

[0156] It should be noted that the angle between the third connecting arm 441 and the fourth connecting arm 442 can be adjusted according to actual needs.

[0157] In some embodiments, the third connecting arm 441 and the fourth connecting arm 442 may be integrally formed.

[0158] It should be noted that, in some other embodiments, the transmission rod 44 may be formed by connecting a third connecting arm 441 and a fourth connecting arm 442 which are separate parts.

[0159] See also Figure 10 and Figure 11 As shown, in some embodiments, the shelf 3 may be provided with a first retaining rib 36. The first retaining rib 36 may be provided on one side of the locking member 41. When the elastic member 43 drives the locking member 41 to rotate toward the first direction, the locking member 41 may rotate in the direction of the first retaining rib 36. When the locking member 41 rotates to abut against the first retaining rib 36, the locking portion 413 may extend into the engaging groove 221, so that the locking portion 413 is supported on the hanging ear 22, thereby supporting the shelf 3 on the hanging ear 22. Thus, the first retaining rib 36 can be used to limit the rotation of the locking member 41, thereby preventing the locking portion 413 from rotating too much under the drive of the elastic member 43, thereby preventing the locking portion 413 from mismatching with the locking portion 413, thereby making the rotation of the locking portion 413 more stable.

[0160] In some embodiments, the shelf 3 may be provided with a second retaining rib 37. The second retaining rib 37 may be located on a side of the locking member 41 away from the first retaining rib 36. When the locking member 41 rotates about the first rotating shaft 42 in the second direction, the locking member 41 may rotate toward the second retaining rib 37. When the locking member 41 abuts the second retaining rib 37, the locking portion 413 separates from the engaging groove 221. Thus, the second retaining rib 37 can limit the reverse rotation of the locking member 41 in the first direction.

[0161] In some embodiments, a limiting channel 38 can be formed between the first retaining rib 36 and the second retaining rib 37. The locking member 41 is rotatably disposed within the limiting channel 38. The first connecting arm 411 is rotatably disposed within the limiting channel 38. Thus, the first connecting arm 411 can rotate within the limiting channel 38. The limiting channel 38 can then be used to limit the rotation angle of the locking member 41, preventing the locking member 41 from rotating excessively and improving the stability of the locking member 41's rotation.

[0162] See also Figure 6 and Figure 13 As shown, in some embodiments, a telescopic opening 332 can be defined on the side wall of the shelf 3. The telescopic opening 332 can be located on the side wall of the shelf 3 near the slide slot 32. The locking portion 413 can extend through the telescopic opening 332 into the slide slot 32 and engage with the engaging groove 221 on the hanging ear 22, thereby supporting the shelf 3 on the back side of the door body 2. Thus, the telescopic opening 332 can limit the rotation of the locking portion 413, thereby improving the rotational stability of the locking portion 413 at the telescopic opening 332.

[0163] In some embodiments, the telescopic opening 332 can be provided at one end of the limiting channel 38 near the chute 32. The telescopic opening 332 can connect the chute 32 and the limiting channel 38. When the elastic member 43 drives the locking member 41 to rotate toward the first retaining rib 36, the locking portion 413 can extend through the telescopic opening 332 into the chute 32 and engage with the engaging groove 221, thereby supporting the locking portion 413 on the hanging ear 22, thereby supporting the shelf 3 on the hanging ear 22.

[0164] When the button 45 is pressed, the button 45 can drive the locking piece 41 to rotate toward the second retaining rib 37 through the transmission rod 44, and the locking part 413 can exit the slide groove 32 through the telescopic opening 332 and separate from the snap-fit ​​groove 221, thereby enabling the shelf 3 to be raised and lowered along the hanging ear 22, and thus the height of the shelf 3 on the hanging ear 22 can be adjusted.

[0165] When the button 45 is released, the elastic force of the elastic member 43 can drive the locking member 41 to rotate in the first direction, so that the locking portion 413 of the locking member 41 rotates in the direction of the first retaining rib 36, so that the locking portion 413 can move from the limiting channel 38 toward the telescopic opening 332, and the locking portion 413 extends from the telescopic opening 332 into the slide groove 32 and engages with the engaging groove 221.

[0166] Thus, the locking portion 413 can extend into or out of the sliding groove 32 through the telescopic opening 332 , and the telescopic opening 332 can be used to realize the connection or height adjustment between the shelf 3 and the hanging ear 22 .

[0167] See also Figure 6As shown, in some embodiments, the shelf 3 may be provided with a mounting cavity 33. The mounting cavity 33 may be provided on a side of the shelf 3 near the mounting ears 22. The mounting cavity 33 may also be provided on a side of the shelf 3 near the supporting ribs 21. The mounting cavity 33 may be used to mount the push-lift module 4 to protect the push-lift module 4 from damage from external factors.

[0168] Specifically, the locking member 41 is rotatably disposed at one end of the mounting cavity 33 near the slide groove 32. The button 45 is slidably disposed at the top of the mounting cavity 33. The top of the button 45 can be exposed above the mounting cavity 33. The transmission member 44 is rotatably disposed within the mounting cavity 33.

[0169] It should be noted that, in some other embodiments, the press-lift module 4 may not be provided on the installation cavity 33 . The press-lift module 4 may be provided on the outer side wall of the shelf 3 near the hanging ear 22 .

[0170] It should also be noted that, in other embodiments, the pressing and lifting module 4 may not be provided on the installation cavity 33. The installation cavity 33 may be provided at the rear side of the sliding groove 32 or at other locations.

[0171] In some embodiments, two mounting cavities 33 may be provided. The two mounting cavities 33 may be located on opposite sides of the shelf 3 near the two hanging ears 22. The two mounting cavities 33 may be located in front of the two slide slots 32. A press-and-lift module 4 is located in each mounting cavity 33. Thus, the two press-and-lift modules 4 in the two mounting cavities 33 can be engaged with the corresponding engaging grooves 221 in the two hanging ears 22, thereby enabling the opposite sides of the shelf 3 to engage with the engaging grooves 221 on the left and right sides, thereby ensuring the stability of the shelf 3 support.

[0172] It should be noted that, in some other embodiments, the number of the mounting cavities 33 may be three or more, and the number of the mounting cavities 33 may correspond to the number of the hanging ears 22 .

[0173] See also Figure 6 、 Figure 9 、 Figure 10 and Figure 11As shown, in some embodiments, a mounting box 34 may be provided in the mounting cavity 33. The mounting box 34 is detachably mounted in the mounting cavity 33. A pressing channel 342 may be provided at the top of the mounting box 34. A limiting channel 38 may be provided at one end of the mounting box 34 close to the slide groove 43. The press-lift module 4 may be installed on the mounting box 34. Thus, the press-lift module 4 is first installed on the mounting box 35, and then the mounting box 34 is installed in the mounting cavity 33, thereby making the press-lift module 4 and the mounting box 34 modular, and making the press-lift module 4 and the mounting box 34 installed together in the mounting cavity 33, thereby improving the installation efficiency of the press-lift module 4. At the same time, the installation of the press-lift module 4 using the mounting box 34 can facilitate the maintenance of the components on the press-lift module 4.

[0174] In some embodiments, the mounting box 34 may be provided with a fixing hole 341. A fixing post 331 may be provided on the sidewall of the mounting cavity 33. The fixing post 331 may extend into the fixing hole 341. Thus, the mounting box 34 may be positioned and installed in the mounting cavity 33 through the fixing post 331 and the fixing hole 341.

[0175] In some embodiments, there may be multiple fixing holes 341. There may also be multiple fixing posts 331. Multiple fixing posts 331 may be provided in a one-to-one correspondence with multiple fixing holes 341. Thus, multiple fixing posts 331 can simultaneously extend into and engage with multiple fixing holes 341, thereby improving the installation stability between the mounting box 34 and the mounting cavity 33.

[0176] In some embodiments, a block 344 may be protruded from the outer wall of the mounting box 34. The block 344 can reduce the distance between the outer wall of the mounting box 34 and the inner wall of the mounting cavity 33. Thus, the block 344 can further improve the installation stability between the mounting box 34 and the mounting cavity 33.

[0177] See also Figure 6 As shown, in some embodiments, a sliding opening 39 may be provided on the side wall of the shelf 3. The button 45 may be movably disposed in the sliding opening 39. The pressing channel 342 may be opened at the top of the installation box 34. The sliding opening may be provided at one end of the installation cavity 33. The sliding opening 39 may be directly connected to the pressing channel 342. The sliding opening 39 may be arranged opposite to the pressing channel 342. Thus, when the button 45 is pressed downward, the button 45 can slide in the sliding opening 39 and the pressing channel 342. The top end of the button 45 is exposed to the shelf 3 through the sliding opening 39, thereby making it convenient for the user to adjust the button 45.
