[0039] See also Figures 1 to 8The present application provides a refrigeration device, which may include: a door body 200, a door shelf 400 and a rotating clamp 310. The door body 200 may have two limit seats 220 protruding backward. The door shelf 400 may be located between the two limit seats 220. In the direction from top to bottom, the side wall of the door shelf 400 may be inclined toward the center of the door shelf 400 to form a support slope 410. A limit groove 420 may be recessed on the side wall of the door shelf 400. The rotating clamp 310 is rotatably connected to at least one limit seat 220. One end of the rotating clamp 310 may protrude relative to the support slope 410 to form a support portion 311, and the support portion 311 can be supported on the support slope 410. The other end of the rotating clamp 310 may protrude relative to the adjacent limit groove 420 to form a limit portion 312. The rotation direction of the limiting portion 312 and the abutting portion 311 can be opposite. The rotating engaging member 310 has an installation position and a disassembly position. When the rotating engaging member 310 is rotated to the installation position, the limiting portion 312 can rotate toward the limiting groove 420 and be engaged in the limiting groove 420; when the rotating engaging member 310 is rotated to the disassembly position, the limiting portion 312 can rotate away from the limiting groove 420 so that the limiting portion 312 can escape from the limiting groove 420.

[0040] During the installation of the door shelf 400, the door shelf 400 is moved between the two limiting seats 220. Then the door shelf 400 is moved from top to bottom. When the door shelf 400 moves from top to bottom, the abutting inclined surface 410 on the side wall of the door shelf 400 abuts against the abutting portion 311, so that the abutting portion 311 rotates in a direction away from the door shelf 400. The abutting portion 311 rotates to drive the limiting portion 312 to rotate toward the door shelf 400, so that the limiting portion 312 can be engaged in the limiting groove 420, and the rotating engaging member 310 rotates to the installation position. In this way, the door shelf 400 can be quickly and efficiently installed on the door body 200, thereby improving the assembly efficiency of the refrigeration equipment.

[0041] When the door shelf 400 is disassembled, the door shelf 400 is moved upward so that the limiting portion 312 rotates in a direction away from the door shelf 400, and the limiting portion 312 escapes from the limiting groove 420. Thus, the rotating engaging member 310 rotates to the disassembly position, and the door shelf 400 is separated from the door body 200. The user can disassemble the door shelf 400 quickly and efficiently, which is convenient for replacement, cleaning and maintenance of the door shelf 400.

[0042] See also Figures 2 to 5 In this embodiment, the door shelf 400 is detachably connected to the door body 200. When the door shelf 400 is installed on the door body 200, the rotating engaging member 310 is in the installation position. At this time, the door shelf 400 is also in the installation position. When the door shelf 400 is separated from the door body 200, the rotating engaging member 310 is in the removal position. At this time, the door shelf 400 is also in the removal position.

[0043] When the door shelf 400 is installed on the door body 200, the door shelf 400 is firmly limited on the door body 200 by the rotating clamping member 310, so as to facilitate the storage of articles. When the door shelf 400 is disassembled, the door shelf 400 is separated from the rotating clamping member 310, so that the user can take out the door shelf 400 to replace, clean and repair the door shelf 400.

[0044] See also Figure 4 , Figure 5 and Figure 8 In this embodiment, the side wall of the door shelf 400 can be inclined toward the center of the door shelf 400 to form a resisting inclined surface 410. The resisting inclined surface 410 can be limited by the resisting portion 311, so as to facilitate the engagement of the rotating engaging member 310.

[0045] In some embodiments, both side walls of the door shelf 400 may be formed with abutting inclined surfaces 410. In a direction from top to bottom, the two abutting inclined surfaces 410 extend obliquely toward each other.

[0046] In other embodiments, a positioning groove 411 is recessed on the supporting slope 410. When the door shelf 400 rotates to the installation position, the supporting portion 311 slides along the supporting slope 410 into the positioning groove 411, so that the supporting portion 311 is engaged with the positioning groove 411, thereby improving the connection strength between the door shelf 400 and the door body 200.

[0047] See also Figures 2 to 5 , Figure 8 In this embodiment, a limiting groove 420 may be recessed on the side wall of the door shelf 400. The limiting groove 420 can be engaged with and limited by the rotating engaging member 310 to limit the door shelf 400 on the door body 200.

[0048] When the door shelf 400 is in the installation position, the abutting inclined surface 410 abuts against the abutting portion 311, and the limiting groove 420 limits the limiting portion 312, so that the door shelf 400 is firmly limited on the door body 200. When the door shelf 400 is in the removal position, the limiting groove 420 on the door shelf 400 is separated from the limiting portion 312, so that the user can take out the door shelf 400. Thereby, the installation efficiency and removal efficiency of the door shelf 400 are effectively improved, and the time cost during installation and removal is reduced.

[0049] In some embodiments, the bottom wall, front and rear side walls and upper end wall of the limiting groove 420 can abut against the limiting portion 312 to limit the movement of the door rack 400 in the front-to-back direction, the left-to-right direction and the downward direction.

[0050] In this embodiment, a limiting groove 420 is concavely formed on one side of the door shelf 400, and a clamping groove 430 is concavely formed on the other side of the door shelf 400. The door shelf 400 can be limited on the limiting seat 220 by the limiting groove 420 and the clamping groove 430.

[0051] In some embodiments, both side walls of the door shelf 400 may be recessed with limiting grooves 420 to limit the door shelf 400 on the door body 200 .

[0052] In other embodiments, a limiting groove 420 is recessed on one side wall of the door shelf 400, and the other side wall of the door shelf 400 can be supported on the limiting seat 220. The rotating clamp 310 can press the door shelf 400 on the limiting seat 220 so that the door shelf 400 is limited on the door body 200.

[0053] See also Figures 4 to 5 , Figure 8 In this embodiment, the limiting groove 420 can be located below the abutting inclined surface 410. The limiting portion 312 is located below the abutting portion 311. This is to facilitate the engagement and limiting of the rotating engaging member 310 and the door shelf 400. In some embodiments, the positioning groove 411 is located above the abutting inclined surface 410 to limit the position of the abutting portion 311. Therefore, the positioning groove 411 and the limiting groove 420 can jointly improve the connection strength between the door shelf 400 and the door body 200.

[0054] In some embodiments, the limiting groove 420 corresponding to the rotating engaging member 310 can extend downward to pass through the bottom surface of the door shelf 400, so as to facilitate the limiting portion 312 to move into the limiting groove 420 and be limited by the bottom wall and / or the upper end wall of the limiting groove 420.

[0055] In other embodiments, the limiting groove 420 may be located above the abutting inclined surface 410. The limiting portion 312 is located above the abutting portion 311 to facilitate the engagement and limiting of the rotating engaging member 310 with the door shelf 400.

[0056] In other embodiments, the limiting groove 420 can be formed on the abutting inclined surface 410. The limiting portion 312 and the abutting portion 311 are arranged at intervals in the vertical direction, so that the rotating engaging member 310 can rotate under the action of the abutting inclined surface 410, and the limiting portion 312 can be engaged with the limiting groove 420.

[0057] See also Figures 1 to 8 In this embodiment, the door body 200 is rotatably covered on the box body 100 to open and close the refrigeration compartment, thereby facilitating the storage of articles.

[0058] See also Figures 2 to 3 , Figures 6 to 8In this embodiment, the door body 200 may be formed with two limit seats 220 protruding backward. The two limit seats 220 may extend in the up-down direction. The two limit seats 220 are arranged at intervals in the left-right direction to limit the two sides of the door shelf 400, thereby limiting the door shelf 400 on the door body 200.

[0059] The limiting seat 220 may have an accommodation space 221. The rotating engaging member 310 may be accommodated in the accommodation space 221. The limiting seat 220 may have an abutting hole 222 corresponding to the abutting portion 311, and the abutting portion 311 may move in the abutting hole 222. The limiting seat 220 may have a limiting hole 223 corresponding to the limiting portion 312, and the limiting portion 312 may move in the limiting hole 223. This facilitates the installation and removal of the rotating engaging member 310 and the door shelf 400.

[0060] In some embodiments, a foaming space 210 may be provided in the door body 200. The foaming space 210 in the door body 200 may be connected to the accommodating space 221 in the limiting seat 220. A foaming structure may be provided in the foaming space 210 and the accommodating space 221. The foaming structure can improve the cold insulation, reliability and safety of the door body 200.

[0061] Fig. 9 It is a structural schematic diagram of the protection box and the rotating clamping piece of the utility model. Fig.10 It is a structural schematic diagram of a rotary engaging piece and a part of a protective box of the utility model.

[0062] See also Figures 8 to 10 In this embodiment, the limit seat 220 may further include a protection box 240. The protection box 240 may be accommodated in the accommodation space 221. The protection box 240 may fit a side wall of the limit seat 220 close to the door shelf 400. The rotating clamp 310 may be rotatably accommodated in the protection box 240. On the one hand, the volume of the door body 200 can be reduced and the space utilization rate of the refrigeration equipment can be improved. On the other hand, the rotating clamp 310 can be protected and the stable and safe rotation of the rotating clamp 310 is facilitated.

[0063] The protection box 240 may be provided with a first through hole 241 relative to the abutting hole 222, and the abutting portion 311 may extend out of the protection box 240 through the first through hole 241. The protection box 240 may be provided with a second through hole 242 relative to the limiting hole 223, and the limiting portion 312 may extend out of the protection box 240 through the second through hole 242. This facilitates the rotation of the abutting portion 311 and the limiting portion 312 of the rotating engaging member 310.

[0064] In some embodiments, the protection box 240 can be attached to the rear side wall of the door body 200 and the side wall of the limiting seat 220 close to the door shelf 400, thereby improving the connection strength between the protection box 240 and the door body 200.

[0065] In some embodiments, the rear side wall of the door body 200 may be provided with two protection boxes 240. The two protection boxes 240 abut and are connected to the rear side wall of the door body 200. The door shelf 400 can be limited between the two protection boxes 240 to limit the door body 200 on the door body 200.

[0066] Fig.11 It is a structural schematic diagram of the rotary engaging member and the elastic member of the utility model.

[0067] See also Figures 3 to 6 , Figures 8 to 11 In this embodiment, the refrigeration device may further include a rotating engaging member 310. The rotating engaging member 310 may be rotatably connected to the door body 200. One end of the rotating engaging member 310 protrudes relative to the supporting inclined surface 410 to form a supporting portion 311. The other end of the rotating engaging member 310 protrudes relative to the limiting groove 420 to form a limiting portion 312.

[0068] The rotating engaging member 310 can be limited with the door shelf 400. When the door shelf 400 rotates from the disassembly position to the installation position, the abutting inclined surface 410 of the door shelf 400 can abut against the abutting portion 311, and drive the abutting portion 311 to rotate away from the center of the door shelf 400, and the limiting portion 312 rotates toward the door shelf 400.

[0069] When the door rack 400 is located at the installation position, the abutting portion 311 abuts against the abutting inclined surface 410 , and the limiting portion 312 abuts against and is limited in the limiting groove 420 .

[0070] When the door shelf 400 rotates from the installation position to the removal position, the door shelf 400 moves upward relative to the door body 200. The limiting portion 312 moves downward relative to the limiting groove 420 and escapes from the limiting groove 420 from the lower end of the limiting groove 420.

[0071] When the door rack 400 is located at the disassembly position, the abutting portion 311 is separated from the abutting inclined surface 410 , and the limiting portion 312 escapes from the limiting groove 420 .

[0072] See also Figures 4 to 6 , Figures 8 to 11 In this embodiment, the abutting portion 311 is located at the upper end of the rotating engaging member 310. The limiting portion 312 is located at the lower end of the rotating engaging member 310. The middle portion of the rotating engaging member 310 is rotatably connected to the door body 200, and the abutting portion 311 rotates in opposite directions to the limiting portion 312.

[0073] See also Figures 4 to 6 , Figures 8 to 11In this embodiment, the rotating engaging member 310 is located in the accommodating space 221, and the middle part of the rotating engaging member 310 is rotatably connected to the limiting seat 220. The abutting end can extend out of the limiting seat 220 through the abutting hole 222 to abut against the abutting inclined surface 410. The limiting portion 312 can extend out of the limiting seat 220 through the limiting hole 223 to engage with the inner wall of the limiting groove 420 for limiting.

[0074] In some embodiments, there is a gap between the rotating engaging member 310 and a side wall of the limiting seat 220 close to the door shelf 400 , so as to facilitate the rotation of the rotating engaging member 310 .

[0075] In some embodiments, in the direction away from the middle of the rotating clamp 310, both ends of the rotating clamp 310 can be tilted toward the door shelf 400. This can reduce the rotation angle of the rotating clamp 310, and facilitate the clamping and limiting of the rotating clamp 310 and the door shelf 400. It can also reduce the volume of the rotating clamp 310, so as to reduce the production cost of the rotating clamp 310 and facilitate the production and installation of the rotating clamp 310.

[0076] See also Figure 8 and Fig.10 In this embodiment, a support member 243 may be further provided in the door body 200. The support member 243 may extend along the spacing direction of the two limiting seats 220. One end of the support member 243 is connected to the limiting seat 220, and the other end of the support member 243 is rotatably connected to the rotating clamping member 310. Thus, there is a spacing between the rotating clamping member 310 and the side wall of the limiting seat 220, which facilitates the rotation of the rotating clamping member 310.

[0077] In some embodiments, the support member 243 can be accommodated in the protection box 240 . The support member 243 extends in the left-right direction. One end of the support member 243 is rotatably connected to the rotating engaging member 310 , and the other end of the support member 243 is connected to the inner wall of the protection box 240 .

[0078] See also Figures 8 to 11 In this embodiment, the cross-sectional area of ​​the abutting portion 311 gradually decreases in the direction toward the center of the door shelf 400, so that the abutting portion 311 is triangular in shape. When the door shelf 400 rotates from the disassembly position to the installation position, the side wall of the triangular abutting portion 311 is convenient for contacting the bottom of the door shelf 400. Thus, the door shelf 400 is guided, and the relative position of the door shelf 400 in the left-right direction is adjusted, thereby improving the installation accuracy and efficiency of the door shelf 400.

[0079] In some embodiments, in a plane perpendicular to the front-rear direction, the end of the abutting portion 311 near the center of the door body 200 is in an arc transition, so as to facilitate the abutment between the abutting portion 311 and the door shelf 400, protect the door shelf 400, prevent the abutting portion 311 from scratching and damaging the door shelf 400, and improve the safety of the refrigeration equipment.

[0080] See also Figures 4 to 5 , Figures 8 to 11 In this embodiment, the limiting portion 312 is prism-shaped, so that the limiting portion 312 and the inner wall of the limiting groove 420 can be engaged and limited. Thus, the door shelf 400 can be firmly and stably limited on the door body 200.

[0081] See also Figures 4 to 5 , Figures 8 to 11 In this embodiment, a guiding slope 313 is provided on one side of the end of the limiting portion 312 close to the door shelf 400 , and the guiding slope 313 extends obliquely toward the door shelf 400 .

[0082] In some embodiments, the guiding slope 313 is arranged on the upper end of the limiting portion 312 close to the door shelf 400 . The guiding slope 313 facilitates the limiting portion 312 to rotate and extend into the limiting groove 420 , thereby improving the installation efficiency of the door shelf 400 and the door body 200 .

[0083] In other embodiments, the guiding slope 313 is disposed on the lower end of the limiting portion 312 near the door shelf 400. The guiding slope 313 facilitates the limiting portion 312 to escape from the limiting groove 420, so as to improve the disassembly efficiency of the door shelf 400 and the door body 200.

[0084] In some embodiments, in a plane perpendicular to the front-rear direction, the side of the stopper 312 close to the door shelf 400 is arc-shaped, so as to facilitate the separation of the bottom wall of the stopper groove 420 and the stopper 312. In other embodiments, in the direction from top to bottom, the bottom wall of the stopper groove 420 is inclined toward the center of the bottom end of the door shelf 400, so as to facilitate the separation of the bottom wall of the stopper groove 420 and the stopper 312. Thereby, the disassembly efficiency of the door shelf 400 and the door body 200 can be improved.

[0085] In some embodiments, the edges and corners of the limiting portion 312 are all arc-shaped transitions, so as to facilitate the alignment of the limiting portion 312 and the limiting groove 420 and prevent the limiting portion 312 from scratching the inner wall of the limiting groove 420.

[0086] See also Figures 8 to 10In this embodiment, the rotating engaging member 310 is rotatably accommodated in the protection box 240. The supporting member 243 is connected to the inner wall of the protection box 240 and the rotating engaging member 310. The abutting portion 311 can extend out of the limiting seat 220 through the first through hole 241 and the abutting hole 222, so that the abutting portion 311 can abut against the abutting inclined surface 410. The limiting portion 312 can extend out of the limiting seat 220 through the second through hole 242 and the limiting hole 223, so that the limiting portion 312 can be engaged with the inner wall of the limiting groove 420 for limiting.

[0087] See also Figure 8 and Fig.10 In this embodiment, an elastic member 320 is further disposed in the door body 200, and the elastic member 320 connects the rotating engaging member 310 and the door body 200. The elastic member 320 can apply elastic force to the rotating engaging member 310, so that the rotating engaging member 310 can rotate from the installation position to the removal position.

[0088] In some embodiments, the elastic member 320 is located in the protection box 240. The elastic member 320 can connect the rotating engaging member 310 and the inner wall of the protection box 240.

[0089] When the rotating engaging member 310 rotates from the disassembly position to the installation position, the door rack 400 moves from top to bottom, and the abutting inclined surface 410 abuts against the abutting portion 311, and applies pressure to the abutting portion 311, so that the abutting portion 311 rotates around the supporting member 243. The rotating engaging member 310 applies force to the elastic member 320 during the rotation process, and the elastic member 320 absorbs the force of the rotating engaging member 310 and converts it into elastic potential energy.

[0090] When the door shelf 400 rotates from the installation position to the removal position, the door shelf 400 moves from bottom to top. The abutting inclined surface 410 moves upward, so that the abutting portion 311 gradually rotates toward the door shelf 400 under the action of the elastic member 320, and the limiting portion 312 gradually rotates away from the door shelf 400 under the action of the elastic member 320. Thus, the limiting portion 312 can escape from the limiting groove 420, which facilitates the separation of the door shelf 400 and the door body 200.

[0091] In some embodiments, the elastic member 320 may be a compression spring. The elastic member 320 is disposed on a side of the abutting portion 311 away from the door shelf 400. The elastic member 320 is connected to the rotating engaging member 310 and a side wall of the protection box 240 away from the door shelf 400.

[0092] In some embodiments, the elastic member 320 may be a tension spring, which is disposed on a side of the limiting portion 312 away from the door rack 400 , so as to apply elastic force to the rotating engaging member 310 .

[0093] In other embodiments, the elastic member 320 may also be a torsion spring, which is disposed at the connection between the support member 243 and the rotating engaging member 310 to provide elastic force for the rotating engaging member 310 .

[0094] In some other embodiments, the rotating engaging member 310 is located outside the limiting seat 220. The rotating engaging member 310 is rotatably connected to at least one limiting seat 220.

[0095] In some other embodiments, the rotating engaging member 310 is rotatably connected to the protection box 240. When the rotating engaging member 310 is in the disassembly position, the center of gravity of the limiting portion 312 is located outside the door shelf 400.

[0096] When the door shelf 400 rotates from the disassembly position to the installation position, the abutting inclined surface 410 applies pressure to the abutting portion 311 , so that the limiting portion 312 rotates toward the door shelf 400 and engages in the limiting groove 420 , and the door shelf 400 is limited on the door body 200 .

[0097] When the door shelf 400 rotates from the installation position to the removal position, the door shelf 400 is moved upward, and the limiting portion 312 rotates in a direction away from the door shelf 400 under its own gravity. Thus, the limiting portion 312 is disengaged from the limiting groove 420, and the user can disassemble and wash the door shelf 400, which is convenient for cleaning, replacement and maintenance of the door shelf 400.

[0098] See also Figures 4 to 7 In this embodiment, a rotation engaging member 310 is disposed in one limiting seat 220, and a fixed block 250 is protruded from the other limiting seat 220 relative to the slot 430. The fixed block 250 and the rotation engaging member 310 can be respectively engaged with the two side walls of the door shelf 400 to limit the door shelf 400 on the door body 200.

[0099] In some embodiments, in the vertical direction, the height of the fixed block 250 is smaller than the height of the slot 430 , so that the slot 430 can accommodate the fixed block 250 and limit the fixed block 250 to move up and down.

[0100] The height of the limiting portion 312 is smaller than the height of the limiting groove 420 . The limiting groove 420 can accommodate the limiting portion 312 and can stop the limiting portion 312 from moving downward.

[0101] When the door shelf 400 is engaged with the door body 200, the door shelf 400 moves downward so that the fixed block 250 is arranged opposite to the slot 430, and the fixed block 250 can extend into the corresponding slot 430. After that, the door shelf 400 continues to move downward so that the limiting portion 312 abuts against and presses the door shelf 400. Thus, the door shelf 400 moves toward the fixed block 250, so that the door shelf 400 is limited on the fixed block 250. The door shelf 400 is firmly limited on the door body 200.

[0102] When the door shelf 400 needs to be disassembled, the door shelf 400 is moved upward to separate the door shelf 400 from the stopper 312. The door shelf 400 is then moved toward the stopper 312 to allow the fixed block 250 to escape from the slot 430 of the door shelf 400. Thereafter, the door shelf 400 is further moved upward to separate the door shelf 400 from the rotation stopper, and the door shelf 400 is in the disassembly position.

[0103] In some embodiments, the two limiting seats 220 are both provided with a rotating engaging member 310, and both sides of the door shelf 400 are both provided with a limiting groove 420, so as to be able to respectively engage with the limiting grooves 420 on both sides of the door shelf 400. In other embodiments, the limiting grooves 420 on the door shelf 400 corresponding to the two rotating engaging members 310 extend downward to pass through the bottom end of the door shelf 400, so as to facilitate the engagement and limiting of the two rotating engaging members 310 with the door shelf 400.

[0104] In other embodiments, a rotation engaging member 310 is disposed in a limiting seat 220. A limiting groove 420 is recessed on one side of the door shelf 400 so that one side of the door shelf 400 is limited on a limiting seat 220. The other side of the door shelf 400 can be abutted against another limiting seat 220. When the door shelf 400 moves downward, the limiting portion 312 can abut and press one side of the door shelf 400 so that the other side of the door shelf 400 is pressed against the limiting seat 220, thereby limiting the door shelf 400 on the door body 200.

[0105] See also Figures 1 to 11 In the present invention, when the door shelf 400 needs to be installed on the door body 200, the door shelf 400 is moved onto the door body 200 so that the door shelf 400 is in a disassembly position.

[0106] The door shelf 400 is moved from top to bottom so that the door shelf 400 rotates from the disassembly position to the installation position. When the door shelf 400 moves downward, the abutting slope 410 abuts and presses the abutting portion 311. The abutting portion 311 rotates away from the door shelf 400 under the action of pressure. The abutting portion 311 is subjected to force to drive the rotating engaging member 310 to rotate around the support member 243, so that the limiting portion 312 rotates toward the door shelf 400. The limiting portion 312 presses the door shelf 400 so that the fixed block 250 and the limiting portion 312 jointly limit the door shelf 400. During the rotation of the abutting portion 311, part of the kinetic energy is converted into the elastic potential energy of the elastic member 320.

[0107] When the door shelf 400 needs to be disassembled, the door shelf 400 is moved upward, and the elastic member 320 applies elastic force to the rotating engaging member 310 to separate the limiting portion 312 from the door shelf 400. Then the door shelf 400 is moved toward the limiting portion 312 in the left-right direction to make the fixed block 250 escape from the slot 430. After that, it is moved upward again to separate the abutting portion 311 from the abutting inclined surface 410, and the limiting portion 312 escapes from the limiting slot 420, and the door shelf 400 moves to the disassembly state.

[0108] In the present application, when the door shelf 400 is installed on the door body 200, the door shelf 400 is moved between the two limiting seats 220. Then the door shelf 400 is moved from top to bottom. When the door shelf 400 moves from top to bottom, the abutting inclined surface 410 on the door shelf 400 abuts against the abutting portion 311 and presses the abutting portion 311 so that the abutting portion 311 rotates in a direction away from the door shelf 400. The abutting portion 311 rotates to drive the limiting portion 312 to rotate toward the door shelf 400, so that the door shelf 400 extends into and is limited in the limiting groove 420, so that the door shelf 400 can be quickly limited on the door body 200. When the door shelf 400 is disassembled, the door shelf 400 moves upward, and the limiting portion 312 rotates away from the door shelf 400 to escape from the limiting groove 420. Thereby, the disassembly efficiency of the door rack 400 and the door body 200 is improved, and the replacement, cleaning and maintenance of the door rack 400 are facilitated.
