In this way, by arranging multiple clamping grooves 211 in a vertical direction on the rack 21, the multiple clamping grooves 211 can be arranged at different heights of the rack 21, so that the door shelf 3 can be clamped with the clamping grooves 211 of different heights, thereby adjusting the height position of the shelf on the rack 21, and thereby adjusting the height position of the door shelf 3 on the door body 2.

[0081] In some embodiments, the clamping grooves 211 on the left and right racks 21 can be arranged in a one-to-one correspondence. In this way, by using the corresponding two clamping grooves 211 on the two racks 21, the left and right sides of the door shelf 3 can be supported, thereby making the door shelf 3 more stable on the rack 21, avoiding the inclination of the door shelf 3, and thereby avoiding the falling of the objects in the door shelf 3.

[0082] In some embodiments, the plurality of card slots 211 can be arranged at equal intervals. In this way, by using the plurality of card slots 211 at equal intervals, the door shelf 3 can be adjusted at equal intervals in height.

[0083] It should be noted that in some embodiments, the plurality of card slots 211 can also be arranged at unequal intervals. In this way, by using the plurality of card slots 211 at unequal intervals, the door shelf 3 can be fixed at different specific heights of the rack 21 to place various articles of different heights.

[0084] It should be noted that in some embodiments, the card slot 211 can be concave only on one rack 21. In this way, the other rack 21 can not be provided with a card slot 211, thereby reducing the cost of the rack 21 while ensuring that the door shelf 3 can be supported.

[0085] It should also be noted that in some embodiments, one rack 21 can be provided with a card slot 211, and the other rack 21 can be provided with a card block. One side of the door shelf 3 can be carded with the card slot 211, and the other side of the door shelf 3 can be carded with the card block.

[0086] Please refer to Figure 7 In some embodiments, the rack 21 can be provided with a plurality of card teeth 212. The plurality of card teeth 212 can be arranged vertically and spaced apart on the rack 21. The card slot 211 can be formed between two adjacent card teeth 212. In this way, by arranging the plurality of card teeth 212 vertically and spaced apart on the rack 21, the plurality of card teeth 212 can be arranged at different heights of the rack 21, thereby the plurality of card slots 211 are arranged at different heights of the rack 21. Therefore, the door shelf 3 can be carded with the card slot 211 of different heights to adjust the height position of the shelf on the rack 21, thereby adjusting the height position of the shelf on the door body 2.

[0087] In some embodiments, the card tooth 212 can be trapezoidal. The card slot 211 can be arranged between two trapezoidal card teeth 212. When the door shelf 3 is carded with the card slot 211, the door shelf 3 can be supported on the top of the trapezoidal card tooth 212. In this way, by using the trapezoidal card tooth 212, the bottom surface of the card slot 211 is a plane, thereby when the door shelf 3 is carded with the card slot 211, the door shelf 3 can be supported on the plane of the trapezoidal, thereby improving the support stability between the door shelf 3 and the card slot 211.

[0088] Please refer to Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the back side of the door body 2 can be provided with a support rib 22. The support rib 22 can be protruded on the back side of the door body 2. The support rib 22 can be arranged in a vertical extension. The support rib 22 can be provided with two. The two support ribs 22 can be arranged in a left-right interval. The door shelf 3 can be movably arranged between the two support ribs 22. Thus, the two support ribs 22 can be used to limit the left-right position of the door shelf 3, thereby improving the stability of the door shelf 3 between the two support ribs 22, and further improving the stability of the door shelf 3 on the door body 2.

[0089] In some embodiments, the rack 21 can be arranged on the support rib 22. The rack 21 can be arranged on the side wall of the support rib 22 facing the other support rib 22. The door shelf 3 can be slidably arranged on the support rib 22 through the rack 21, thereby enabling the door shelf 3 to slide up and down along the extension direction of the support rib 22, thereby enabling the height position of the door shelf 3 on the support rib 22 to be adjusted, and further enabling the height position of the door shelf 3 on the door body 2 to be adjusted.

[0090] It should be noted that in other embodiments, the rack 21 can not be arranged on the support rib 22, but directly on the back side wall of the door body 2.

[0091] In some embodiments, when the rack 21 is provided with two, one of the racks 21 can be arranged on one of the support ribs 22. The other rack 21 can be arranged on the other support rib 22. The two racks 21 can be arranged on the opposite side walls of the two support ribs 22, respectively. In this way, the two support ribs 22 can be used to limit the left-right position of the door shelf 3. At the same time, the door shelf 3 can slide up and down relative to the two racks 21, so that the door shelf 3 can slide up and down relative to the two support ribs 22, and then the two support ribs 22 can be used to limit the left-right position of the door shelf 3, so that the door shelf 3 can slide up and down more stably between the two support ribs 22.

[0092] It should be noted that in other embodiments, when the rack 21 is provided with two, one of the racks 21 can be arranged on the support rib 22. The other rack 21 can not be arranged on the support rib 22, but on other areas of the back side of the door body 2.

[0093] It should also be noted that in other embodiments, when the rack 21 is provided with two, neither of the two racks 21 can be arranged on the support rib 22, but on other areas of the back side of the door body 2.

[0094] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, in some embodiments, the side wall of the door body 2 can be provided with a sliding rail 23. The sliding rail 23 can be vertically arranged. The sliding rail 23 can be arranged on one side of the door shelf 3. The door shelf 3 can be in sliding connection with the sliding rail 23. The door shelf 3 can slide up and down along the extension direction of the sliding rail 23. Thus, the user can control the door shelf 3 to slide up and down relative to the sliding rail 23, thereby adjusting the height position of the door shelf 3 on the sliding rail 23.

[0095] In some embodiments, the sliding rail 23 can be provided with two. The two sliding rails 23 can be arranged on the back side of the door body 2. The two sliding rails 23 can be respectively arranged on the left and right opposite sides of the door shelf 3. The door shelf 3 can be in sliding connection with the two sliding rails 23 respectively. Thus, the user can control the door shelf 3 to slide up and down relative to the two sliding rails 23, and limit the sliding of the door shelf 3 by the two sliding rails 23, thereby improving the stability of the door shelf 3 when sliding up and down.

[0096] It should be noted that in other embodiments, the two sliding rails 23 can be arranged on the back side or other positions of the door shelf 3. The sliding rail 23 can be provided with three or more than three.

[0097] It should be further noted that in other embodiments, the sliding rail 23 can be provided with three or more than three.

[0098] In some embodiments, the rack 21 can be arranged on the sliding rail 23. The rack 21 can be arranged on the side wall of the sliding rail 23. The rack 21 can be arranged on the side of the sliding rail 23 facing the door shelf 3. Thus, when the door shelf 3 slides up and down relative to the sliding rail 23, the door shelf 3 can be clamped with the clamping groove 211 of the rack 21 on the sliding rail 23, so that the door shelf 3 can be supported on the sliding rail 23, thereby enabling the door shelf 3 to be supported at different height positions on the sliding rail 23.

[0099] It should be noted that in other embodiments, when the sliding rail 23 is provided with two, one of the sliding rails 23 can be provided with a rack 21, and the other sliding rail 23 can not be provided with a rack 21.

[0100] In some embodiments, the sliding rail 23 can be arranged on the support rib 22. The sliding rail 23 can be arranged on the side wall of the support rib 22 facing the other support rib 22. The door shelf 3 can be slidably arranged on the support rib 22 through the sliding rail 23, thereby enabling the door shelf 3 to slide up and down along the extension direction of the support rib 22, thereby adjusting the height position of the door shelf 3 on the support rib 22, and thereby adjusting the height position of the door shelf 3 on the door body 2.

[0101] It should be noted that in other embodiments, the sliding rail 23 can not be arranged on the support rib 22, but directly on the back side wall of the door body 2.

[0102] In some embodiments, when two slide rails 23 are provided, one of the slide rails 23 can be arranged on one of the support ribs 22. The other slide rail 23 can be arranged on the other support rib 22. Alternatively, the two slide rails 23 can be arranged on the opposite side walls of the two support ribs 22 respectively. In this way, the door shelf 3 can be limited leftward and rightward by the two support ribs 22. Meanwhile, the door shelf 3 can slide upward and downward relative to the two slide rails 23, so that the door shelf 3 can slide upward and downward relative to the two support ribs 22, and then the door shelf 3 can be limited leftward and rightward by the two support ribs 22, so that the door shelf 3 can slide upward and downward between the two support ribs 22 more stably.

[0103] It should be noted that in other embodiments, when two slide rails 23 are provided, one of the slide rails 23 can be arranged on the support rib 22. The other slide rail 23 can not be arranged on the support rib 22, but arranged on other regions of the back side of the door body 2.

[0104] It should be further noted that in other embodiments, when two slide rails 23 are provided, neither of the two slide rails 23 can be arranged on the support rib 22, but arranged on other regions of the back side of the door body 2.

[0105] Please refer to Figure 5 In some embodiments, the door shelf 3 can be provided with a sliding groove 32. The sliding groove 32 can be arranged on the outer side wall of the door shelf 3. The sliding groove 32 can be arranged in a vertical direction. The slide rail 23 can be slidably arranged in the sliding groove 32. The door shelf 3 can slide upward and downward relative to the slide rail 23 through the sliding groove 32, so as to adjust the height of the door shelf 3 on the door body 2, and thus the door shelf 3 can be used to place articles of different heights. In addition, the sliding groove 32 and the slide rail 23 can be used to limit the sliding of the door shelf 3, so as to improve the stability of the door shelf 3 when the door shelf 3 slides upward and downward.

[0106] In some embodiments, the sliding groove 32 can be provided with two. The two sliding grooves 32 can be arranged on the two opposite side walls of the door shelf 3 respectively. The two slide rails 23 can be slidably arranged in the sliding grooves 32 respectively. In this way, the two slide rails 23 can be limited by the two sliding grooves 32, so that the left and right sides of the door shelf 3 can slide upward and downward along the two slide rails 23 synchronously, and thus the stability of the door shelf 3 when the door shelf 3 slides upward and downward can be further improved.

[0107] It should be noted that in other embodiments, the sliding groove 32 can be provided with three or more. The number of the sliding grooves 32 can correspond to the number of the slide rails 23.

[0108] Figure 8 is Figure 3 a schematic view of part of the structure. Figure 9 is Figure 8 an exploded view of Figure 10 is Figure 9A structural schematic view of the adjustment assembly 4. Figure 11 is Figure 10 an exploded view. Figure 12 is Figure 2 a sectional view from a certain perspective. Figure 13 is Figure 12 an enlarged view of part B.

[0117] Please refer to Figure 6 and Figure 7 , in some embodiments, the back side of the door body 2 can be provided with a lifting channel 24. The lifting channel 24 can be provided on one side of the rack 21. The lifting channel 24 is arranged in parallel with the rack. The lifting channel 24 can be provided on one side of the door shelf 3. The lifting channel 24 can be arranged vertically. The lifting channel 24 can be in communication with the transverse end of the clamping groove 211. The clamping piece 41 can extend into the lifting channel 24 and slide up and down along the lifting channel 24, so that the adjusting assembly 4 can slide along the lifting channel 24, and the door shelf 3 can slide along the lifting channel 24 to adjust the height of the lifting channel 24 on the back side of the door body 2.

[0118] In some embodiments, the clamping piece 41 can enter the clamping groove 211 from the transverse end of the lifting channel 24 through the clamping groove 211, and the clamping piece 41 can be clamped in the clamping groove 211, so that the adjusting assembly 4 can be clamped on the rack 21.

[0119] In some embodiments, the clamping piece 41 can enter the lifting channel 24 from the transverse end of the clamping groove 211, so that the clamping piece 41 can slide into the lifting channel 24, and the clamping piece 41 can slide up and down along the lifting channel 24, and the door shelf 3 can slide up and down along the lifting channel 24.

[0120] In some embodiments, the lifting channel 24 can be arranged on the side wall of the slide rail. The vertical two ends of the slide rail 23 can be respectively provided with openings. The two openings can be respectively communicated with the upper and lower ends of the lifting channel 24, so that the clamping part 411 can be slid into the lifting channel 24 through any opening or slid out of the slide rail 23 through any opening, thereby enabling the door shelf 3 to be mounted between the two slide rails 23 or dismounted from the two slide rails 23. Thus, the two openings of the slide rail 23 can facilitate the user to mount or dismount the door shelf 3.

[0121] Figure 14 is Figure 8 an exploded view. Figure 15 is Figure 14 is an enlarged view of part C in Figure 16 is Figure 15 a structural schematic view in another state.

[0122] Referring to Figure 14 , Figure 15 and Figure 16 , in some embodiments, the side wall of the door shelf 3 can be provided with a first guide groove 33. The first guide groove 33 can be arranged on the side wall of the door shelf 3 close to the rack 21 and the lifting channel 24. The arrangement direction of the first guide groove 33 is parallel to the arrangement direction of the clamping part 411. One end of the first guide groove 33 is arranged opposite to the rack 21. The other end of the first guide groove 33 is arranged opposite to the lifting channel 24. The clamping part 41 is slidably arranged in the first guide groove 33.

[0123] When the user does not need to adjust the height of the door shelf 3 on the door body 2, the user can drive the clamping part 41 to slide towards the end of the first guide groove 33 close to the rack 21, so that the clamping part 41 can drive the clamping part 411 to move towards the end of the rack 21, thereby enabling the clamping part 411 to enter the rack slot 211 from the transverse end of the rack slot 211 through the lifting channel 24, and enabling the clamping part 411 to be clamped in the rack slot 211, thereby enabling the door shelf 3 to be supported on the rack 21.

[0124] When the user needs to adjust the height of the door shelf 3 on the door body 2, the user can drive the clamping part 41 to slide towards the end of the first guide groove 33 close to the lifting channel 24, so that the clamping part 41 can drive the clamping part 411 to move towards the end of the lifting channel 24, thereby enabling the clamping part 411 to enter the lifting channel 24 from the transverse end of the rack slot 211, thereby enabling the clamping part 41 to enter the lifting channel 24, thereby enabling the door shelf 3 to slide up and down on the rack 21, thereby enabling the height position of the door shelf 3 on the door body 2 to be adjusted, so that different height and size of articles can be placed in the door shelf 3.

[0125] Thus, the user can slide the clamping member 41 along the first guide slot 33 in different directions to support the door shelf 3 on the door body 2 or slide the door shelf 3 up and down on the door body 2, thereby improving the convenience of the up and down operation of the door shelf 3 on the door body 2.

[0126] In some embodiments, the first guide slot 33 can be formed on the slot side wall of the sliding slot 32. Thus, the clamping member 41 can be arranged in the sliding slot 32, thereby enabling the clamping member 41 to slide relative to the door shelf 3.

[0127] In some embodiments, the adjusting assembly 4 can include a first sliding column 412. One end of the first sliding column 412 can be connected with the clamping member 41. The other end of the first sliding column 412 can be arranged in the first guide slot 33 and can slide along the first guide slot 33, thereby enabling the clamping member 41 to slide along the first guide slot 33. Thus, the clamping member 41 can be limited in sliding in the first guide slot 33 by the first sliding column 412, thereby improving the stability of the sliding of the clamping member 41 in the first guide slot 33 by the first sliding column 412.

[0128] Please refer to Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 15 and Figure 16 In some embodiments, the adjusting assembly 4 can include a knob 42. The knob 42 can be movably arranged on the door shelf 3. At least part of the knob 42 can be exposed outside the outer wall of the door shelf 3. The knob 42 can be in transmission connection with the clamping member 41. The user can drive the clamping member 41 to move along the first guide slot 33 by rotating the part of the knob 42 exposed outside the door shelf 3.

[0129] Specifically, when the user does not need to adjust the height of the door shelf 3 on the door body 2, the user can drive the clamping member 41 to slide along the first guide slot 33 towards the end of the first guide slot 33 close to the rack 21 by the knob 42, so as to support the door shelf 3 on the rack 21.

[0130] When the user needs to adjust the height of the door shelf 3 on the door body 2, the user can drive the clamping member 41 to slide along the first guide slot 33 towards the end of the first guide slot 33 close to the lifting passage 24 by the knob 42, so as to slide the door shelf 3 up and down on the lifting passage 24, thereby adjusting the height position of the door shelf 3 on the door body 2.

[0131] Thus, driving the clamping member 41 to move along the first guide slot 33 by the knob 42, thereby improving the convenience of the user's operation of adjusting the height position of the door shelf 3.

[0132] In some embodiments, the knob 42 can be arranged on the top of the door shelf 3. At least a part of the knob 42 can protrude from the top wall of the door shelf 3. In this way, the user can drive the clamping member 41 to slide along the first guide slot 33 by the knob 42 protruding from the top of the door shelf 3, so as to facilitate the user to adjust the knob 42, thereby improving the convenience of the user to adjust the height position of the door shelf 3.

[0133] It should be noted that in other embodiments, the knob 42 can be arranged on the bottom or other positions of the door shelf 3. At least a part of the knob 42 can protrude from the bottom wall or other side wall of the door shelf 3.

[0134] Figure 17 is a sectional view of Figure 2 . Figure 18 is an enlarged view of part D of Figure 17 . Figure 19 is a sectional view of Figure 18 . Figure 20 is a structural schematic view of the door shelf in another state. Figure 19 is a structural schematic view of part of

[0135] Please refer to Figure 9 , Figure 10 , Figure 11 , Figure 17 , Figure 18 , Figure 19 and Figure 20 , in some embodiments, the adjusting assembly 4 can include a transmission member 43. The transmission member 43 is rotatably arranged in the sliding groove 32. One end of the transmission member 43 can be in transmission connection with the knob 42. The other end of the transmission member 43 can be in transmission connection with the clamping member 41.

[0136] When the user does not need to adjust the height of the door shelf 3 on the door body 2, the user can drive the knob 42 to move towards the end of the lifting channel 24 away from the rack 21, so that the knob 42 drives the transmission member 43 to rotate, thereby causing the clamping member 41 to move reversely relative to the knob 42, i.e. causing the clamping member 41 to slide along the first guide slot 33 towards the end away from the lifting channel 24, i.e. causing the clamping member 41 to slide along the first guide slot 33 towards the end close to the rack 21, thereby causing the clamping portion 411 on the clamping member 41 to be able to extend into the clamping slot 211 from the transverse end of the clamping slot 211 through the lifting channel 24, thereby realizing the clamping of the clamping portion 411 and the clamping slot 211.

[0137] When the user needs to adjust the height of the door shelf 3 on the door body 2, the user can drive the push block 42 to move towards the end of the rack 21 away from the lifting channel 24, so that the push block 42 drives the transmission member 43 to rotate, and then the clamping member 41 moves reversely relative to the push block 42, that is, the clamping member 41 slides along the first guide groove 33 towards the end of the rack 21 away from the lifting channel 24, that is, the clamping member 41 slides along the first guide groove 33 towards the end of the lifting channel 24, and then the clamping part 411 on the clamping member 41 can enter the lifting channel 24 through the transverse end of the clamping groove 211, so that the door shelf 3 slides up and down on the lifting channel 24, and then the height position of the door shelf 3 on the door body 2 can be adjusted.

[0138] Therefore, the transmission between the push block 42 and the clamping member 41 can be better realized by the transmission member 43, so that the operation of supporting and adjusting the lifting of the door shelf 3 on the door body 2 is realized.

[0139] It should be noted that in other embodiments, the transmission member 43 can be arranged on the door shelf 3 without rotating, but is directly connected between the push block 42 and the clamping member 41. Therefore, when the user does not need to adjust the height of the door shelf 3 on the door body 2, the user can drive the push block 42 to move towards the end of the rack 21, so that the transmission member 43 moves towards the end of the rack 21, and the clamping member 41 moves along the first guide groove 33 towards the end of the rack 21. When the user does not need to adjust the height of the door shelf 3 on the door body 2, the user can drive the push block 42 to move towards the end of the lifting channel 24, so that the transmission member 43 moves towards the end of the lifting channel 24, and the clamping member 41 moves along the first guide groove 33 towards the end of the lifting channel 24.

[0140] In some embodiments, the adjusting assembly 4 can include a rotating shaft member. The rotating shaft member can be arranged through the side wall of the door shelf 3 and the transmission member 43, so that the transmission member 43 can rotate relative to the rotating shaft member, and then the transmission member 43 can rotate relative to the door shelf 3. Therefore, the stability of the rotation of the transmission member 43 relative to the door shelf 3 can be improved by the rotating shaft member.

[0141] In some embodiments, a second guide groove 34 can be arranged on the side wall of the door shelf 3. The second guide groove 34 can be arranged on one side of the first guide groove 33. The arrangement direction of the second guide groove 34 can be parallel to the arrangement direction of the first guide groove 33. The push block 42 is slidably arranged in the second guide groove 34.

[0142] When the user does not need to adjust the height of the door shelf 3 on the door body 2, the user can drive the push block 42 to move along the second guide groove 34 towards the end of the lifting channel 24 away from the gear rack 21, so that the clamping piece 41 slides along the first guide groove 33 towards the end close to the gear rack 21, and then the clamping part 411 on the clamping piece 41 can be inserted into the clamping groove 211 from the transverse end of the clamping groove 211 through the lifting channel 24, so as to realize the clamping of the clamping part 411 and the clamping groove 211.

[0143] When the user needs to adjust the height of the door shelf 3 on the door body 2, the user can drive the push block 42 to move along the second guide groove 34 towards the end of the lifting channel 24 away from the gear rack 21, so that the clamping piece 41 slides along the first guide groove 33 towards the end close to the gear rack 21, and then the clamping part 411 on the clamping piece 41 can be inserted into the clamping groove 211 from the transverse end of the clamping groove 211 through the lifting channel 24, so as to realize the clamping of the clamping part 411 and the clamping groove 211.

[0144] Thus, the sliding of the push block 42 can be limited by the second guide groove 34, and the stability of the user when driving the push block 42 to slide can be improved.

[0145] In some embodiments, the adjusting assembly 4 can include a second sliding column 44. One end of the second sliding column 44 can be connected with the push block 42. The other end of the second sliding column 44 can be arranged in the second guide groove 34 and can slide along the second guide groove 34, so that the push block 42 can slide along the second guide groove 34. Thus, the push block 42 can be limited in the second guide groove 34 by the second sliding column 44, and the stability of the push block 42 in the second guide groove 34 can be improved by the second sliding column 44.

[0146] Please refer to Figure 10 、 Figure 11 、 Figure 17 、 Figure 18 、 Figure 19 and Figure 20 In some embodiments, the adjusting assembly 4 can include a first movable rod 45. The end of the transmission member 43 close to the clamping piece 41 can be provided with a first telescopic groove 431. One end of the first movable rod 45 can be telescopically arranged in the first telescopic groove 431. The other end of the first movable rod 45 is exposed outside the transmission member 43. The clamping piece 41 is rotatably arranged at the end of the first movable rod 45 exposed to the transmission member 43.

[0147] When the user does not need to adjust the height of the door shelf 3 on the door body 2, the user can drive the push block 42 to move towards the end of the lifting channel 24 away from the rack 21, so that the transmission member 43 rotates, and the transmission member 43 drives the first movable rod 45 to rotate relative to the clamping member 41, so that the first movable rod 45 inserted into one end of the first telescopic slot 431 slides along the first telescopic slot 431, and the first movable rod 45 drives the clamping member 41 to move along the first guide slot 33 towards the end close to the rack 21, so that the clamping part 411 can be inserted into the clamping groove 211 from the transverse end of the lifting channel 24, and the clamping part 411 and the clamping groove 211 are clamped.

[0148] When the user needs to adjust the height of the door shelf 3 on the door body 2, the user can drive the push block 42 to move towards the end of the lifting channel 24 away from the rack 21, so that the transmission member 43 rotates, and the transmission member 43 drives the first movable rod 45 to rotate relative to the clamping member 41, so that the first movable rod 45 inserted into one end of the first telescopic slot 431 slides along the first telescopic slot 431, and the first movable rod 45 drives the clamping member 41 to move along the first guide slot 33 towards the end close to the rack 21, so that the clamping part 411 can be inserted into the clamping groove 211 from the transverse end of the lifting channel 24, and the clamping part 411 and the clamping groove 211 are clamped.

[0149] Thus, by using the first movable rod 45 and the first telescopic slot 431, when the transmission member 43 rotates, the transmission member 43 can drive the clamping member 41 to move transversely through the first movable rod 45, so that the clamping member 41 can be clamped with the clamping groove 211 or separated from the clamping groove 211, thereby realizing that the door shelf 3 is clamped on the rack 21 or slides up and down relative to the rack 21.

[0150] In some embodiments, when the clamping member 41 is clamped with the clamping groove 211, the transmission member 43 and the first movable rod 45 can be parallel to the extension direction of the rack 21.

[0151] When the user does not need to adjust the height of the door shelf 3 on the door body 2, the transmission member 43 drives the first movable rod 45 to rotate, so that the distance between the end of the first movable rod 45 away from the transmission member 43 and the rotating shaft of the transmission member 43 decreases, and the first movable rod 45 slides along the first telescopic slot 431 towards the inside of the first telescopic slot 431.

[0152] When the user needs to adjust the height of the door shelf 3 on the door body 2, the transmission member 43 drives the first movable rod 45 to rotate reversely, so that the distance between the end of the first movable rod 45 away from the transmission member 43 and the rotating shaft of the transmission member 43 increases, and the first movable rod 45 reversely slides along the first telescopic slot 431 towards the outside of the first telescopic slot 431.

[0153] It should be noted that in some other embodiments, when the clamping piece 41 is clamped with the clamping groove 211, the transmission piece 43 and the first movable rod 45 can be arranged at an angle with the extension direction of the rack 21.

[0154] Please refer to Figure 10 、 Figure 11 、 Figure 17 、 Figure 18 、 Figure 19 and Figure 20 , in some embodiments, the adjusting assembly 4 can include a first elastic piece 46. The first elastic piece 46 can be arranged in the first telescopic groove 431. One end of the first elastic piece 46 can abut against the first movable rod 45. The other end of the first elastic piece 46 can abut against the side wall of the first telescopic groove 431. The first elastic piece 46 can provide elastic force to the first movable rod 45 to move the first movable rod 45 towards the outside of the first telescopic groove 431. Thus, when the user needs to adjust the height of the door shelf 3 on the door body 2, the user drives the push block 42 to drive the transmission piece 43 to rotate reversely, so that the first movable rod 45 slides along the first telescopic groove 431 towards the outside of the first telescopic groove 431, and the first elastic piece 46 can provide elastic force for the sliding of the first movable rod 45, and further provide pushing force for the movement of the clamping piece 41 by the elastic force, and further provide pushing force for the movement of the clamping piece 41 by the elastic force, and further reduce the force required by the user to drive the push block 42, and further save the user's effort, and facilitate the user's operation.

[0155] In some embodiments, the first elastic piece 46 can be a spring. One end of the spring can abut against the first movable rod 45. The other end of the spring can abut against the side wall of the first telescopic groove 431.

[0156] It should be noted that in some other embodiments, the elastic piece can also be other elastic devices.

[0157] In some embodiments, the first elastic piece 46 can be provided with two. The two first elastic pieces 46 can be arranged at intervals. The two first elastic pieces 46 can be arranged parallel to each other. The two first elastic pieces 46 can respectively abut against the ends of the first movable rod 45 away from the push block 42, so that the two first elastic pieces 46 can simultaneously provide elastic force to the first movable rod 45, and further improve the elastic force received by the first movable rod 45, and further improve the pushing force received by the clamping piece 41, so that the user can more easily drive the push block 42 to push the clamping piece 41 through the transmission piece 43, and further save the user's effort.

[0158] It should be noted that in some other embodiments, the first elastic piece 46 can be three or more.

[0159] Please refer to Figure 17, Figure 18 , Figure 19 and Figure 20 As shown, in some embodiments, a first limiting groove 432 may be formed on the transmission member 43. The first limiting groove 432 may be formed on the side wall of the first telescopic groove 431. The first limiting groove 432 may communicate with the first telescopic groove 431. The first limiting groove 432 extends along the telescopic direction of the first movable rod 45. A first hook 451 may be provided on the first movable rod 45. The first hook 451 can extend into the first limiting groove 432. The first hook 451 can slide along the first limiting groove 432.

[0160] When the user does not need to adjust the height of the door shelf 3 on the door body 2, the transmission component 43 drives the first movable rod 45 to rotate, so that the first movable rod 45 slides along the first telescopic groove 431 toward the inside of the first telescopic groove 431, so that the first hook 451 slides along the first limiting groove 432 toward the inside of the first telescopic groove 431.

[0161] When the user needs to adjust the height of the door shelf 3 on the door body 2, the transmission component 43 drives the first movable rod 45 to rotate in the opposite direction, so that the first movable rod 45 slides in the opposite direction along the first telescopic groove 431 toward the outside of the first telescopic groove 431, so that the first hook 451 slides in the opposite direction along the first limiting groove 432 toward the outside of the first telescopic groove 431.

[0162] Therefore, the first limiting groove 432 can limit the sliding of the first hook 451, thereby limiting the sliding of the first movable rod 45 within the first telescopic groove 431, thus preventing the first movable rod 45 from sliding out of the first telescopic groove 431. At the same time, by using the first hook 451 to slide along the first limiting groove 432, the sliding of the first hook 451 can be made more stable, thereby making the sliding of the first movable rod 45 within the first telescopic groove 431 more stable.

[0163] In some embodiments, two first limiting grooves 432 may be provided. The two first limiting grooves 432 may be respectively provided on opposite side walls of the first telescopic groove 431. The two first limiting grooves 432 may be arranged opposite to each other. First hooks 451 are respectively provided on opposite sides of the first movable rod 45. One first hook 451 can be slidably limited within one of the first limiting grooves 432, and the other first hook 451 can be slidably limited within the other first limiting groove 432. Therefore, by using the two first limiting grooves 432 to limit the two first hooks 451 respectively, the stability of the first hooks 451 sliding within the two first limiting grooves 432 can be improved, thereby improving the stability of the first movable rod 45 sliding within the first telescopic groove 431.

[0164] It should be noted that in other embodiments, the first limiting groove 432 can be provided with three or more than three. The first clamping hook 451 can be provided with three or more than three.

[0165] Please refer to Figure 10 、 Figure 11 、 Figure 17 、 Figure 18 、 Figure 19 and Figure 20 , in some embodiments, the adjusting assembly 4 can include a second movable rod 47. The end of the transmission member 43 close to the knob 42 can be provided with a second telescopic groove 433. One end of the second movable rod 47 is telescopically provided in the second telescopic groove 433. The other end of the second movable rod 47 is exposed outside the transmission member 43. The knob 42 is rotatably provided at the exposed end of the transmission member 43 of the second movable rod 47.

[0166] When the user does not need to adjust the height of the door shelf 3 on the door body 2, the user can drive the knob 42 to move towards the end close to the lifting channel 24 away from the rack 21, so that the second movable rod 47 rotates relative to the knob 42, thereby making the transmission member 43 rotate, and the end of the second movable rod 47 extending into the second telescopic groove 433 slides along the second telescopic groove 433, and the clamping member 41 drives the clamping member 41 to move along the first guide groove 33 towards the end close to the rack 21, thereby enabling the clamping part 411 to extend into the clamping groove 211 from the lifting channel 24 through the transverse end of the clamping groove 211, and realizing the clamping of the clamping part 411 and the clamping groove 211.

[0167] When the user needs to adjust the height of the door shelf 3 on the door body 2, the user can drive the knob 42 to move towards the end close to the rack 21 away from the lifting channel 24, so that the second movable rod 47 rotates relative to the knob 42 in the opposite direction, thereby making the transmission member 43 rotate in the opposite direction, and the end of the second movable rod 47 extending into the second telescopic groove 433 slides along the second telescopic groove 433 in the opposite direction, and the clamping member 41 drives the knob 42 to move along the first guide groove 33 towards the end close to the lifting channel 24, thereby enabling the clamping member 41 to enter the lifting channel 24 from the clamping groove 211 through the transverse end thereof, so that the door shelf 3 slides up and down on the lifting channel 24, thereby being able to adjust the height position of the door shelf 3 on the door body 2.

[0168] Thus, the knob 42 drives the second movable rod 47 and the second telescopic groove 433 to rotate, so that the knob 42 can drive the clamping member 41 to move transversely through the second movable rod 47 and the transmission member 43, so that the clamping member 41 can be clamped with or separated from the clamping groove 211, thereby realizing the clamping of the door shelf 3 on the rack 21 or the sliding of the door shelf 3 on the rack 21.

[0169] In some embodiments, when the clamping piece 41 is clamped with the clamping groove 211, the transmission piece 43 and the second movable rod 47 can be parallel to the extending direction of the rack 21.

[0170] When the user does not need to adjust the height of the door shelf 3 on the door body 2, the knob 42 drives the second movable rod 47 and the transmission piece 43 to rotate, so that the distance between the end of the second movable rod 47 away from the transmission piece 43 and the rotating shaft of the transmission piece 43 is reduced, and then the second movable rod 47 slides along the second telescopic groove 433 towards the inside of the second telescopic groove 433.

[0171] When the user needs to adjust the height of the door shelf 3 on the door body 2, the knob 42 drives the second movable rod 47 and the transmission piece 43 to rotate, so that the distance between the end of the second movable rod 47 away from the transmission piece 43 and the rotating shaft of the transmission piece 43 is increased, and then the second movable rod 47 reversely slides along the second telescopic groove 433 towards the outside of the second telescopic groove 433.

[0172] It should be noted that in other embodiments, when the clamping piece 41 is clamped with the clamping groove 211, the transmission piece 43 and the second movable rod 47 can be arranged at an angle with the extending direction of the rack 21.

[0173] Please refer to Figure 10 , Figure 11 , Figure 17 , Figure 18 , Figure 19 and Figure 20 , in some embodiments, the adjusting assembly 4 can include a second elastic piece 48. The second elastic piece 48 can be arranged in the second telescopic groove 433. One end of the second elastic piece 48 can abut against the second movable rod 47. The other end of the second elastic piece 48 can abut against the side wall of the second telescopic groove 433. The second elastic piece 48 can provide an elastic force to the second movable rod 47 to move towards the outside of the second telescopic groove 433. Thus, when the user needs to adjust the height of the door shelf 3 on the door body 2, the user drives the knob 42 to reversely rotate the second movable rod 47 and the transmission piece 43, so that the second movable rod 47 reversely slides along the second telescopic groove 433 towards the outside of the second telescopic groove 433, and the second elastic piece 48 can provide an elastic force for the reversely sliding of the second movable rod 47, and then the elastic force can provide a pushing force for the movement of the knob 42, and then the force required by the user to drive the knob 42 can be reduced, and then the user can save the force and facilitate the operation of the user.

[0174] In some embodiments, the second elastic piece 48 can be a spring. One end of the spring can abut against the second movable rod 47. The other end of the spring can abut against the side wall of the second telescopic groove 433.

[0175] It should be noted that in other embodiments, the second elastic member 48 can also be other elastic devices.

[0176] In some embodiments, the second elastic member 48 can be provided with two. The two second elastic members 48 can be spaced apart. The two second elastic members 48 can be arranged in parallel with each other. The two second elastic members 48 can be respectively abutted with the end of the second movable rod 47 away from the knob 42, so that the two second elastic members 48 can simultaneously provide the second movable rod 47 with elastic force, thereby improving the elastic force received by the second movable rod 47, and thereby improving the pushing force received by the knob 42, so that the user drives the knob 42 more labor-saving.

[0177] It should be noted that in other embodiments, the second elastic member 48 can be three or more.

[0178] Please refer to Figure 17 , Figure 18 , Figure 19 and Figure 20 shown, in some embodiments, the transmission member 43 can be provided with a second limiting slot 434. The second limiting slot 434 can be provided on the slot side wall of the second telescopic slot 433. The second limiting slot 434 can be in communication with the second telescopic slot 433. The second limiting slot 434 is arranged along the telescopic direction of the second movable rod 47. The second movable rod 47 can be provided with a second hook 471. The second hook 471 can extend into the second limiting slot 434. The second hook 471 can slide along the second limiting slot 434.

[0179] When the user does not need to adjust the height of the door shelf 3 on the door body 2, the second movable rod 47 is not driven to rotate, so that the second movable rod 47 slides along the second telescopic slot 433 towards the inside of the second telescopic slot 433, so that the second hook 471 slides along the second limiting slot 434 towards the inside of the second telescopic slot 433.

[0180] When the user needs to adjust the height of the door shelf 3 on the door body 2, the knob 42 drives the second movable rod 47 to rotate reversely, so that the second movable rod 47 reversely slides along the second telescopic slot 433 towards the outside of the second telescopic slot 433, so that the second hook 471 reversely slides along the second limiting slot 434 towards the outside of the second telescopic slot 433.

[0181] Thus, the second limiting slot 434 can limit the sliding of the second hook 471, and thereby limit the sliding of the second movable rod 47 in the second telescopic slot 433, and thereby avoid the second movable rod 47 from sliding out of the second telescopic slot 433. At the same time, the second hook 471 slides along the second limiting slot 434, and thereby the sliding of the second hook 471 is more stable, and thereby the sliding of the second movable rod 47 in the second telescopic slot 433 is more stable.

[0182] In some embodiments, the second limiting slot 434 can be provided with two. The two second limiting slots 434 can be respectively provided on the opposite two side walls of the second telescopic slot 433. The two second limiting slots 434 can be oppositely arranged. The opposite two sides of the second movable rod 47 are respectively provided with the second clamping hook 471. One of the second clamping hooks 471 can be slidably limited in one of the second limiting slots 434, and the other second clamping hook 471 can be slidably limited in the other second limiting slot 434. Thus, by limiting the two second clamping hooks 471 with the two limiting slots respectively, the stability of the second clamping hook 471 sliding in the two second limiting slots 434 can be improved, and thus the stability of the second movable rod 47 sliding in the second telescopic slot 433 can be improved.

[0183] It should be noted that in other embodiments, the second limiting slot 434 can be provided with three or more. The second clamping hook 471 can be provided with three or more.

The interior of the sliding part 36 can be formed with a sliding groove 32. The protective shell 35 can be attached to the side wall of the sliding part 36 away from the sliding groove 32. The sliding part 36 can be provided with a first guide slot 33 and a second guide slot 34. Thus, by using the protective shell 35, the first guide slot 33 and the second guide slot 34 can be covered on the side wall away from the sliding groove 32, and then the protective shell 35 can separate the first guide slot 33, the second guide slot 34 and the storage groove 31, and then avoid the items in the storage groove 31 entering the first guide slot 33 and the second guide slot 34, and then avoid affecting the sliding of the clamping piece 41 along the first guide slot 33 and the sliding of the push block 42 along the second guide slot 34.

[0185] In some embodiments, the sliding part 36 can be provided with two. The two sliding parts 36 can be provided on the opposite two side walls of the door shelf 3. The protective shell 35 can be provided with two. One of the protective shells 35 can be covered on the side wall of one of the sliding parts 36 close to the other sliding part 36. The other protective shell 35 can be covered on the side wall of the other sliding part 36 close to the sliding part 36.

[0186] Please refer to Figure 14 , Figure 15 and Figure 16As shown, in some embodiments, the sliding part 36 can be provided with a first sliding wall 361, a second sliding wall 362 and a third sliding wall 363 on the side wall away from the sliding groove 32. The first sliding wall 361 can be provided on the side wall of one sliding part 36 close to the other sliding part 36. The second sliding wall 362 can be provided on one side of the first sliding wall 361. The third sliding wall 363 can be provided on the other side of the first sliding wall 361.

The second cover plate 352 can be provided on the side wall of the second sliding wall 362. The third cover plate 353 can be provided on the side wall of the third sliding wall 363. Thus, by providing the first cover plate 351, the second cover plate 352 and the third cover plate 353 on the first sliding wall 361, the second sliding wall 362 and the third sliding wall 363 respectively, the protective shell 35 can fully cover the sliding part 36, thereby fully protecting the sliding part 36 from damage by the articles in the article slot 31.

[0187] In some embodiments, the inner wall of the protective shell 35 can be provided with a clamping rib (not labeled in the figure). The side wall of the sliding part 36 away from the sliding groove 32 can be provided with a mounting groove 364. The mounting groove 364 can be arranged vertically. The clamping rib can slide along the mounting groove 364. When the protective shell 35 is provided on the side wall of the sliding part 36 away from the sliding groove 32, the clamping rib can extend into the mounting groove 364 and slide along the extension direction of the mounting groove 364, so that the protective shell 35 is provided on the side wall of the sliding part 36 away from the sliding groove 32. Thus, by limiting the sliding between the clamping rib and the mounting groove 364, the stability of the cover between the protective shell 35 and the sliding part 36 can be improved.

[0188] In some embodiments, the clamping rib can be provided with two. The two clamping ribs are arranged on the inner wall of the protective shell 35. The sliding part 36 can be provided with two mounting grooves 364. The two mounting grooves 364 can be arranged on the side wall of the sliding part 36 away from the sliding groove 32.
