The extension portion 413 can drive the first rotating member 411 to rotate. The second rotating member 421 is rotatably connected to the door body 200. The front end of the second rotating member 421 may be transmission-connected to the first rotating member 411. The rear end of the second rotating member 421 can pass through the door body 200. The rear end of the second rotating member 421 can be arranged opposite to the slot 310. The first rotating member 411 can drive the second rotating member 421 to rotate, so that the rear end of the second rotating member 421 can move toward the door shelf 300 and engage in the slot 310, thereby limiting the door shelf 300 on the door body 200.

[0040] When the door shelf 300 is installed, the user moves the extension part 413 so that the first rotating member 411 drives the second rotating member 421 to rotate, and the rear end of the second rotating member 421 moves away from the center of the door body 200. The door shelf 300 is moved onto the door body 200, and the rear end of the second rotating member 421 is arranged opposite to the slot 310. Then the user moves the extension part 413, and the first rotating member 411 drives the second rotating member 421 to rotate, so that the rear end of the second rotating member 421 moves toward the door shelf 300 and is engaged in the slot 310, thereby firmly limiting the door shelf 300 on the door body 200, effectively improving the installation efficiency of the door shelf 300.

[0041] When the door shelf 300 needs to be disassembled, the user moves the extension part 413, the first rotating member 411 drives the second rotating member 421 to rotate, and the rear end of the second rotating member 421 moves out of the card slot 310 to disassemble the door shelf 300. The quick-release card structure 400 can quickly disassemble the door shelf 300 while ensuring the connection strength between the door shelf 300 and the door body 200, thereby facilitating the replacement, cleaning and maintenance of the door shelf 300 and improving the user's disassembly and use efficiency.

[0042] See also Figures 2 to 6In this embodiment, a foaming space 210 may be provided in the inner opening of the door body 200. The foaming space 210 is used to accommodate the quick-release snap-fit ​​structure 400, thereby effectively reducing the space occupancy rate of the quick-release snap-fit ​​structure 400 and improving the space utilization rate of the refrigeration equipment.

[0043] See also Figures 2 to 6 In this embodiment, the rear end wall of the door body 200 may have two limit protrusions 230 extending backward. The limit protrusions 230 may extend in the up-down direction. The two limit protrusions 230 may be respectively located on both sides of the door shelf 300.

Figure 8 yes Figure 7 A cross-sectional view of the structure shown in FIG. Fig. 9 yes Figure 8 A structural schematic diagram of another perspective of the structure shown in .

[0047] See also Figures 5 to 9 In this embodiment, the door body 200 may include a working box 240. The working box 240 may be located in the foaming space 210. The working box 240 is connected to the rear end wall of the door body 200. The working box 240 includes a working space 241. The quick-release snap-fit ​​structure 400 may be accommodated in the working space 241 to ensure safe and stable operation of the quick-release snap-fit ​​structure 400.

[0048] The working box 240 includes a first working portion 242 and a second working portion 243. The first working portion 242 can be attached to and limited on the rear end wall of the door body 200. The second working portion 243 can be located in the limiting protrusion 230. The second working portion 243 can be attached to a side wall of the limiting protrusion 230 close to the door shelf 300, thereby reducing the rotation angle and movement stroke of the quick-release clamping structure 400, thereby facilitating the movement of the quick-release clamping structure 400.

[0049] In some embodiments, the working spaces 241 in the first working portion 242 and the second working portion 243 are connected to facilitate the installation of the quick-release engaging structure 400. The first rotating member 411 is rotatably connected to the first working portion 242. The second rotating member 421 is rotatably located in the second working portion 243. This allows the quick-release engaging structure 400 to operate safely and stably.

[0050] In other embodiments, the working box 240 may be located in the door body 200. The first working portion 242 may be attached to the rear end wall of the door body 200. The second working portion 243 extends backward to pass through the rear end wall of the door body 200. The second working portion 243 may be located on at least one side of the door shelf 300. A limited opening 231 is provided on a side wall of the second working portion 243 close to the door shelf 300.

[0051] In other embodiments, the working box 240 can be disposed in close contact with the rear end wall of the door body 200. The second rotating member 421 passes through the working box 240 and the door body 200 backwards, so that the second rotating member 421 can be engaged with the slot 310 of the door shelf 300.

[0052] See also Figures 5 to 9 In this embodiment, the working box 240 may be provided with a through hole relative to the starting opening 221 and the limiting opening 231 , so as to facilitate the extension portion 413 and the second rotating member 421 to pass through the door body 200 .

[0053] In some other embodiments, the working box 240 opens toward one side of the rear end wall of the door body 200 so that the working box 240 covers the rear end wall of the door body 200. The rear end wall of the door body 200 and the working box 240 enclose a working space 241.

[0054] In some embodiments, a foaming structure (not shown) may be provided in the foaming space 210. The foaming structure can be filled between the inner wall of the door body 200 and the working box 240, so that the working box 240 is stably and firmly connected to the rear end wall of the door body 200. Thus, the stability and safety of the quick-release snap-fit ​​structure 400 are ensured.

[0055] In some embodiments, there is an arc-shaped transition between the rear end wall of the door body 200 and the limiting protrusion 230. There is an arc-shaped transition between the first working portion 242 and the second working portion 243.

[0056] Fig.10 It is a structural schematic diagram of the quick-release clamping structure and part of the working box of the utility model. Fig.11 It is a structural schematic diagram of the first rotating member, the second rotating member and the elastic member of the utility model.

[0057] See also Figures 6 to 11 In this embodiment, the quick-release snap-fit ​​structure 400 can be accommodated in the working box 240. The user can adjust the connection state between the door shelf 300 and the door body 200 through the quick-release snap-fit ​​structure 400. Thus, the door shelf 300 can be quickly disassembled while ensuring the connection strength between the door shelf 300 and the door body 200, so as to facilitate replacement, cleaning and maintenance.

[0058] The quick-release engaging structure 400 can switch between an engaged state and a disassembled state. When the quick-release engaging structure 400 is in the engaged state, the rear end of the second rotating member 421 is engaged in the engaging slot 310. When the quick-release engaging structure 400 switches from the engaged state to the disassembled state, the rear end of the second rotating member 421 can rotate in a direction away from the center of the door body 200, so that the rear end of the second rotating member 421 can move out and away from the engaging slot 310.

[0059] See also Figure 6 , Figures 8 to 11 In this embodiment, the quick-release engaging structure 400 includes a first rotating member 411 and a second rotating member 421 that can be connected in a transmission manner. The first rotating member 411 is rotatably connected to the rear end wall of the door body 200. The second rotating member 421 is rotatably connected to the upper portion of the limiting protrusion 230. This facilitates the engagement of the quick-release engaging structure 400 with the door shelf 300.

[0060] The first rotating member 411 may extend in the left-right direction. The middle portion of the first rotating member 411 may be rotatably connected to the door body 200. The second rotating member 421 may be located at an end of the first rotating member 411 away from the center of the door body 200. The second rotating member 421 may extend in the front-back direction. The middle portion of the second rotating member 421 may be rotatably connected to the door body 200. The rear end of the second rotating member 421 may be movable toward the door shelf 300, so that the rear end of the second rotating member 421 may pass through the door body 200 through the limiting opening 231 and be limited by the slot 310.

[0061] The first rotating member 411 is located on a side of the second rotating member 421 close to the center of the door body 200 , so as to effectively improve the space utilization rate in the door body 200 , reduce the total volume of the door body 200 , and thus reduce the production cost of the door body 200 .

[0062] In this embodiment, the first rotating member 411 may be located in the first working portion 242. The middle portion of the first rotating member 411 is rotatably connected to the first working portion 242. An end of the first rotating member 411 away from the second rotating member 421 may be provided with an extension portion 413.

[0063] In other embodiments, the distance between the extension 413 and the rotation axis 415 of the first rotating member 411 is greater than the distance between the rotation axis 415 of the first rotating member 411 and the end of the first rotating member 411 away from the extension 413. According to the lever principle, when the extension 413 drives the first rotating member 411 to rotate, the user only needs to apply a small force to the extension 413 to push the second rotating member 421 to rotate. This can effectively improve the installation and disassembly efficiency of the door shelf 300 and improve the use efficiency of the refrigeration equipment.

[0064] In some embodiments, a connection portion 412 may be protruded downward from one end of the first rotating member 411 away from the second rotating member 421. The lower portion of the connection portion 412 extends downward beyond the door shelf 300. The extension portion 413 is disposed on the connection portion 412 so that the extension portion 413 is located at the lower side of the door shelf 300. This facilitates the hidden arrangement of the extension portion 413 and prevents the user from accidentally touching the extension portion 413.

[0065] In some embodiments, a first abutting rib 451 may be convexly provided on the first rotating member 411. The first abutting rib 451 can abut against the rear end wall of the door body 200. The first abutting rib 451 can limit the rotation angle of the first rotating member 411, so as to reduce the pressure strength at the rotation point of the first rotating member 411, reduce the fatigue wear degree of the first rotating member 411, and increase the service life of the first rotating member 411.

[0066] In other embodiments, the first abutting ribs 451 can be respectively disposed on the front and rear sides of the first rotating member 411. The first abutting ribs 451 can respectively abut against the front and rear side walls of the working box 240 to further limit the rotation angle of the first rotating member 411.

[0067] In other embodiments, the first abutting rib 451 may be disposed on the working box 240. The first abutting rib 451 is disposed relative to the first rotating member 411 so that the first abutting rib 451 can limit the rotation angle of the first rotating member 411.

[0068] In other embodiments, the first retaining rib 451 may be disposed on the connecting portion 412 to limit the rotation angle of the first rotating member 411 .

[0069] See also Figure 6 , Figures 8 to 11In this embodiment, the quick-release engaging structure 400 may further include an elastic member 431. The elastic member 431 may be disposed between the first rotating member 411 and the inner wall of the door body 200. The elastic member 431 may apply an elastic force to the first rotating member 411 to drive the first rotating member 411 to rotate, so that the rear end of the second rotating member 421 is engaged in the engaging groove 310, and the quick-release engaging structure 400 switches from the disassembly state to the engagement state.

[0070] When the user pulls out or presses the extending portion 413 , the first rotating member 411 drives the second rotating member 421 to rotate, and the second rotating member 421 moves out of the slot 310 , and the quick-release engaging structure 400 can switch from the engaged state to the disassembled state.

[0071] When the quick-release engaging structure 400 switches to the disassembled state, the elastic member 431 can apply elastic force to the first rotating member 411 so that the first rotating member 411 drives the second rotating member 421 to rotate, and the second rotating member 421 moves toward the limiting opening 231, so that the quick-release engaging structure 400 switches to the engaged state.

[0072] See also Figure 6 , Figures 8 to 11 In this embodiment, the elastic member 431 can be a compression spring. The elastic member 431 is located between the first rotating member 411 and the front end wall of the working box 240. The front end of the elastic member 431 abuts against the front end wall of the working box 240. The rear end of the elastic member 431 abuts and is limited to one end of the first rotating member 411 where the extension portion 413 is set. When the user applies a forward force to the extension portion 413, the elastic member 431 can absorb part of the kinetic energy and convert it into elastic potential energy. When the user stops applying force to the extension portion 413, the elastic member 431 can apply a backward elastic force to the first rotating member 411.

[0073] The distance between the elastic member 431 and the rotation axis 415 of the first rotating member 411 is greater than the distance between the rotation axis 415 of the first rotating member 411 and the end of the first rotating member 411 away from the elastic member 431. Thus, a smaller elastic force can stably and reliably drive the second rotating member 421 to rotate.

[0074] In some embodiments, the first rotating member 411 may have an elastic groove (not shown) relative to the elastic member 431 . The elastic groove is used to accommodate and limit the elastic member 431 so that the elastic member 431 can apply elastic force to the first rotating member 411 .

[0075] In other embodiments, the elastic member 431 may be disposed on the connecting portion 412. The elastic member 431 is disposed on the front side of the connecting portion 412 relative to the extending portion 413. When the user applies force to the extending portion 413, and the extending portion 413 drives the first rotating member 411 to rotate, part of the power is directly transmitted to the elastic member 431 through the connecting portion 412 and converted into elastic kinetic energy. This can improve the efficiency of the quick-release engaging structure 400 when it is reset to the engaging state.

[0076] In some embodiments, the elastic member 431 may also be a tension spring. In other embodiments, the elastic member 431 may be located between the first rotating member 411 and the rear end wall of the working box 240 so that the second rotating member 421 can move toward the limiting opening 231 .

[0077] In some embodiments, the quick-release engaging structure 400 may further include a first supporting member 441. One end of the first supporting member 441 is connected to the door body 200, and the other end of the first supporting member 441 is rotatably connected to the middle of the first rotating member 411. The first supporting member 441 can support the first rotating member 411 to rotate.

[0078] See also Figure 6 , Figures 8 to 11 In this embodiment, the second rotating member 421 can be accommodated in the limiting protrusion 230. The second rotating member 421 can extend in the front-to-back direction. The front end of the second rotating member 421 is transmission-connected to the first rotating member 411. The rear end of the second rotating member 421 can extend out of the limiting opening 231 so that the second rotating member 421 and the slot 310 are limited. The second rotating member 421 can be accommodated in the second working portion 243. The middle portion of the second rotating member 421 is rotatably connected to the second working portion 243.

[0079] In some embodiments, the distance between the front end of the second rotating member 421 and the rotation axis 415 of the second rotating member 421 is smaller than the distance between the rear end of the second rotating member 421 and the rotation axis 415 of the second rotating member 421. This allows the first rotating member 411 to provide only a small force to rotate the rear end of the second rotating member 421 to a larger angle, thereby facilitating the second rotating member 421 to move in and out of the slot 310.

[0080] See also Figure 6 , Figures 8 to 11 In this embodiment, a limiting block 423 may be protruded from the rear end of the second rotating member 421 relative to the limiting opening 231. The limiting block 423 is disposed opposite to the slot 310. The limiting protrusion 230 may extend toward the slot 310. The limiting block 423 may rotate around the rotation axis 415 of the second rotating member 421, so that the limiting block 423 may be engaged in the slot 310.

[0081] In some embodiments, the side of one end of the limiting block 423 extending into the slot 310 has an arc-shaped transition, so that the limiting block 423 can extend into the slot 310 after passing through the limiting opening 231 .

[0082] In other embodiments, the lower side wall of the limiting opening 231 can abut against the limiting block 423 so that the limiting protrusion 230 can support and limit the door shelf 300 through the limiting block 423, thereby improving the connection strength between the door shelf 300 and the door body 200.

[0083] In some embodiments, the slot 310 of the door shelf 300 is arranged relative to the position limiting block 423. In the direction toward the center of the door shelf 300, the radial dimension of the slot 310 gradually decreases, so as to facilitate the engagement and limiting of the slot 310 and the position limiting block 423. Thus, the door shelf 300 can be firmly limited on the door body 200 through the position limiting block 423.

[0084] See also Figure 6 , Figures 8 to 11 In this embodiment, in the direction from front to back, the rear end of the second rotating member 421 is tilted toward the door shelf 300. On the one hand, the movement stroke of the limit block 423 can be reduced, so that the rear end of the second rotating member 421 only rotates a small angle, and the limit block 423 can move in and out of the slot 310, thereby improving the user's efficiency. On the other hand, the volume of the working box 240 can be reduced to accommodate the second rotating member 421 and the limit block 423 in the disassembled state. It can not only reduce the production cost of the quick-release snap-fit ​​structure 400, but also ensure that there is a gap between the side wall of the limit protrusion 230 away from the door shelf 300 and the second working part 243, thereby facilitating the filling of the foaming structure and improving the connection strength between the quick-release working box 240 and the rear end wall of the door body 200.

[0085] See also Figure 6 , Figures 8 to 11 In this embodiment, the door body 200 is provided with a second abutting rib 452 at the rear end relative to the second rotating member 421, and the second abutting rib 452 can abut against the second rotating member 421 to limit the rotation angle of the second rotating member 421. In some embodiments, the second abutting rib 452 can be provided on a side wall of the second working portion 243 close to the door shelf 300 to support the second rotating member 421 and limit the rotation angle of the second rotating member 421.

[0086] In some embodiments, the second abutting rib 452 may be disposed on a side wall of the working box 240 close to the door shelf 300 , so that the second abutting rib 452 can abut and limit the rotation angle of the second rotating member 421 .

[0087] In other embodiments, the second abutting ribs 452 may be disposed on the left and right side walls of the working box 240 to limit the rotation angle of the second rotating member 421 .

[0088] See also Figure 6 , Figures 8 to 11 In this embodiment, a transmission structure may be provided between the second rotating member 421 and the first rotating member 411. The second rotating member 421 is connected to the first rotating member 411 through the transmission structure, and the first rotating member 411 can drive the second rotating member 421 to rotate.

[0089] See also Figure 6 , Figures 8 to 11 In this embodiment, a rotating shaft 415 may be provided at one end of the first rotating member 411 close to the second rotating member 421. A moving hole 422 may be provided at the front end of the second rotating member 421. The moving hole 422 may be used to accommodate the rotating shaft 415. The rotating shaft 415 can move in the moving hole 422, and the rotating shaft 415 can abut against the inner circumferential wall of the moving hole 422, so that the first rotating member 411 can drive the second rotating member 421 to rotate through the rotating shaft 415.

[0090] When the user applies force to the extension part 413, so that the extension part 413 drives the first rotating member 411 to rotate, the rotating shaft 415 rotates around the rotating shaft 415 line of the first rotating member 411. The rotating shaft 415 can move in the moving hole 422. The rotating shaft 415 can abut against the inner peripheral wall of the moving hole 422, so that the rotating shaft 415 can drive the second rotating member 421 to rotate. So that the rear end of the second rotating member 421 can move away from the card slot 310, so that the limit card block 423 is separated from the door shelf 300. The quick-release card structure 400 switches from the card state to the disassembly state.

[0091] When the door shelf 300 needs to be assembled, the user applies force to the extension portion 413 to put the quick-release snap-fit ​​structure 400 in a disassembled state. Then the door shelf 300 is placed on the door body 200 so that the door shelf 300 corresponds to the quick-release snap-fit ​​structure 400. The user stops applying force to the extension portion 413, and the first rotating member 411 rotates under the action of the elastic member 431. The first rotating member 411 drives the second rotating member 421 to rotate through the rotating shaft 415. The rear end of the second rotating member 421 rotates toward the door shelf 300 so that the limiting block 423 moves into and engages in the slot 310. The quick-release snap-fit ​​structure 400 switches from the disassembled state to the engaged state to firmly limit the door shelf 300 on the door body 200.

[0092] In some embodiments, the rotation axis 415 may extend along a rotation axis 415 line of the second rotation member 421 .

[0093] In other embodiments, the rotating shaft 415 may be a rolling bearing to improve the transmission efficiency of the first rotating member 411 and the second rotating member 421 .

[0094] In some embodiments, the transmission structure may further include a sliding shaft and a sliding groove. The sliding shaft is disposed on the first rotating member 411. The sliding groove is disposed on the second rotating member 421. The sliding shaft is slidably accommodated in the sliding groove. The sliding shaft can abut against the inner peripheral wall of the sliding groove. When the first rotating member 411 rotates, the sliding shaft rotates around the rotating shaft 415 of the first rotating member 411. The sliding shaft can slide in the sliding groove, and the sliding shaft can apply pressure to the inner peripheral wall of the sliding groove to drive the second rotating member 421 to rotate.

[0095] See also Figure 6 , Figures 8 to 11 In this embodiment, the quick-release engaging structure 400 may further include a second supporting member 442 . One end of the second supporting member 442 is connected to the working box 240 ; the other end of the second supporting member 442 is rotatably connected to the middle portion of the second rotating member 421 .

[0096] In some embodiments, the second support member 442 may be located on the second working portion 243. The second support member 442 is disposed near the front end of the second working portion 243, so that when both ends of the second rotating member 421 rotate at the same angle, the movement stroke of the rear end of the second rotating member 421 is greater than the movement stroke of the front end of the second rotating member 421. This facilitates the engagement of the limit block 423 and improves the working efficiency of the quick-release engagement structure 400.

[0097] In other embodiments, the first rotating member 411 may be located on the upper side or lower part of the second rotating member 421. The first rotating member 411 may be accommodated in the limiting protrusion 230. The first rotating member 411 extends in the up-down direction, and the second rotating member 421 extends in the front-back direction. The first rotating member 411 is transmission-connected with the second rotating member 421 to drive the second rotating member 421 to switch between the engaged state and the disassembled state.

[0098] In some other embodiments, the first rotating member 411 and the second rotating member 421 may both extend in the up-down direction. The first rotating member 411 and the second rotating member 421 are transmission-connected to drive the second rotating member 421 to switch between the engaged state and the disassembled state.

[0099] See also Figure 6 , Figures 8 to 11 In this embodiment, a quick-release snap-fit ​​structure 400 may be provided on one side of the door body 200. A snap-fit ​​protrusion 232 may be provided on the other side of the door body 200. A snap-fit ​​groove 310 on one side of the door shelf 300 may be detachably snap-fitted with the limit snap-fit ​​block 423. A snap-fit ​​groove 310 on the other side of the door shelf 300 may be detachably snap-fitted with the snap-fit ​​protrusion 232.

[0100] When the door shelf 300 is installed on the door body 200, the door shelf 300 is first engaged with the engaging protrusion 232. Then the quick-release engaging structure 400 is switched to the engaging state, and the limiting block 423 extends into the engaging groove 310. The engaging protrusion 232 and the limiting block 423 together limit the door shelf 300 on the door body 200. This effectively improves the installation efficiency of the door shelf 300 and the door body 200, and improves the connection strength of the door shelf 300 and the door body 200.

[0101] When the door shelf 300 needs to be disassembled, the user moves the extension part 413 to rotate the first rotating member 411 and the second rotating member 421 so that the limiting block 423 is disengaged from the slot 310. Then, the other side of the door shelf 300 is separated from the engaging protrusion 232. Thus, the door shelf 300 can be quickly disassembled, so as to facilitate the replacement, cleaning and maintenance of the door shelf 300.

[0102] In some embodiments, the engaging protrusion 232 and the limiting block 423 are both prismatic structures, so as to improve the connection strength between the door shelf 300 and the door body 200 .

[0103] In other embodiments, both sides of the door body 200 may be provided with a quick-release snap-fit ​​structure 400. The limiting blocks 423 of the two quick-release snap-fit ​​structures 400 can be respectively limited in the two side slots 310 of the door shelf 300. On the one hand, the door shelf 300 can be firmly limited on the door body 200. On the other hand, it is convenient to quickly disassemble the door shelf 300. The use efficiency of the refrigeration equipment is improved.

[0104] See also Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Fig.11 In this embodiment, a locking portion 250 is further provided on the door body 200. The locking portion 250 is provided relative to the extension portion 413. The extension portion 413 is provided with a locking groove 414 relative to the locking portion 250, and the locking portion 250 is accommodated in the locking groove 414 to limit the moving distance of the extension portion 413.

[0105] In some embodiments, the locking portion 250 may be disposed on the rear end wall of the door body 200. The locking portion 250 may be disposed on the peripheral side of the start opening 221. In other embodiments, the locking portion 250 may be located on the outer side of the door body 200. A support protrusion 260 may protrude upward from the upper portion of the locking portion 250. The support protrusion 260 can abut against the lower surface of the door shelf 300, thereby limiting and supporting the door shelf 300.

[0106] In some embodiments, the locking portion 250 can be connected to the working box 240 through the activation opening 221 .

[0107] In other embodiments, the locking portion 250 may include a locking hook 251. The locking hook 251 is disposed relative to the locking groove 414. The locking hook 251 can move relatively in the locking groove 414. The front end surface of the locking hook 251 can abut against the inner peripheral wall of the front side of the locking groove 414, and the rear end surface of the locking hook 251 can abut against the inner peripheral wall of the rear side of the locking groove 414, so that the locking hook 251 can limit the moving distance of the extension portion 413.

[0108] In some embodiments, in the direction from top to bottom, the rear end face of the locking hook 251 is tilted toward the door body 200. The inner peripheral wall of the rear side of the locking groove 414 is arranged relative to the rear end face of the locking hook 251, so that the rear end face of the locking hook 251 can fit the inner peripheral wall of the locking groove 414. In this way, the volume of the locking portion 250 is reduced while ensuring the movement stroke of the extension portion 413, thereby reducing the production cost of the refrigeration equipment.

[0109] See also Figures 1 to 11 In the present invention, when the door shelf 300 needs to be installed on the door body 200, the user applies force to the extension part 413. The elastic member 431 absorbs kinetic energy and converts it into elastic potential energy. The extension part 413 drives the first rotating member 411 to rotate. The first rotating member 411 drives the rotating shaft 415 to rotate, and the rotating shaft 415 drives the front end of the second rotating member 421 to rotate. So that the limit block 423 on the rear end of the second rotating member 421 moves, and the limit block 423 moves into the limit protrusion 230.

[0110] The user moves the door shelf 300 onto the door body 200 so that the slot 310 on one side of the door body 200 is engaged with the engaging protrusion 232 and the slot 310 on the other side of the door body 200 is arranged opposite to the limiting block 423. The user stops applying external force to the extension portion 413, and the elastic member 431 applies elastic force to the first rotating member 411. The first rotating member 411 rotates under the action of the elastic force. The first rotating member 411 drives the second rotating member 421 to rotate through the rotating shaft 415, so that the limiting block 423 at the rear end of the second rotating member 421 moves toward the slot 310 and engages in the slot 310. Thereby, the engaging protrusion 232 and the limiting block 423 firmly limit the door shelf 300 on the door body 200.

[0111] When the door shelf 300 needs to be disassembled for replacement, cleaning and maintenance, the user applies force to the extension part 413. The extension part 413 drives the first rotating member 411 to rotate. The first rotating member 411 drives the second rotating member 421 to rotate through the rotating shaft 415, so that the limiting block 423 at the rear end of the second rotating member 421 moves away from the slot 310. After the limiting block 423 moves out of the slot 310, the user removes the door shelf 300. This facilitates the quick installation and disassembly of the door shelf 300, and effectively improves the replacement and cleaning efficiency of the door shelf 300.

[0112] In the present application, when the door shelf 300 is installed on the door body 200, the user moves the extension part 413, the first rotating member 411 drives the second rotating member 421 to rotate, and the rear end of the second rotating member 421 moves away from the center of the door body 200. After that, the door shelf 300 is moved onto the door body 200 so that the slot 310 and the second rotating member 421 are arranged opposite to each other. The second rotating member 421 is then driven to rotate by the extension part 413 and the first rotating member 411, and the rear end of the second rotating member 421 extends into the slot 310. The second rotating member 421 limits the door shelf 300 on the door body 200. Thus, while ensuring the connection strength between the door shelf 300 and the door body 200, the disassembly efficiency of the door shelf 300 is improved, and the installation, replacement and cleaning of the door shelf 300 are facilitated.
