[0040] In the description of the present application, the plural refers to more than two. If there is a description of the first, second, only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the order of the technical features indicated.

[0041] In the description of the present application, unless otherwise explicitly limited, the words such as setting, mounting, connecting, etc. should be broadly understood, and the person skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0042] Referring to Figures 1 to 4 As shown in the drawings, an embodiment of the present application is an automated three-dimensional blood bank, which comprises a refrigerated cabinet 100 and a plurality of shelf units 200.

[0043] The interior of the refrigeration cabinet 100 defines a refrigeration cavity, and the refrigeration cabinet 100 is provided with a plurality of access openings 101 at the front side of the refrigeration cavity, and is provided with opening and closing doors 110 at the access openings 101, which are used to open or close the access openings 101. It can be understood that the access openings 101 are used for the single blood box 300 to pass through, and the cross-sectional size of the access openings 101 is slightly larger than the cross-sectional size of the blood box 300. The refrigeration cabinet 100 is provided with an air conditioner to adjust the temperature in the refrigeration cabinet 100. In some embodiments, the opening and closing doors 110 are connected with a telescopic motor for controlling the opening and closing of the opening and closing doors 110. Of course, the telescopic motor can be replaced by a hydraulic cylinder or an oil cylinder, which is a conventional technical means, so it will not be described in detail here. In addition, in order to ensure the sealing, the opening and closing doors 110 and the access openings 101 can be provided with sealing structures such as sealing rubber strips.

[0044] The shelf unit 200 corresponds to the access opening 101 one by one, that is, one shelf unit 200 corresponds to one access opening 101, and the access opening 101 is located directly in front of the corresponding shelf unit 200. Specifically, the shelf unit 200 includes a storage rack 210, a carrier plate 220, a rotary driving device 230, and a pushing device 240.

[0045] Among them, the storage rack 210 is arranged in the refrigeration cabinet 100.

[0046] The carrier plate 220 is horizontally arranged in the storage rack 210, and the center line of the carrier plate 220 extends vertically. The carrier plate 220 can rotate around the vertical center line thereof, and is used to support the blood box 300. A plurality of limiting assemblies are arranged on the carrier plate 220 in a circumferential direction, and the limiting assemblies and the upper surface of the carrier plate 220 define a storage position for storing the blood box 300. A plurality of limiting assemblies correspond to define a plurality of storage positions, and the plurality of storage positions are arranged along the circumferential direction of the carrier plate 220. In addition, the limiting assemblies can move relative to the carrier plate 220 to adjust the size of the storage position, so as to be able to store blood boxes 300 of different specifications. It should be noted that the function of the limiting assembly is to limit the blood box 300, so that the blood box 300 has a stable state when stored. Obviously, the limiting assembly can release the limiting of the blood box 300, so that the blood box 300 can be pushed out of the storage position.

[0047] The rotary driving device 230 is connected with the carrier plate 220, and the rotary driving device 230 can drive the carrier plate 220 to rotate so that any storage position is directly opposite the access opening 101.

[0048] The pushing device 240 is arranged in the storage rack 210 and has a freedom degree of forward and backward movement, and is used to push the blood box 300 in the storage position directly opposite the access opening 101 to the access opening 101.

[0049] Based on the above embodiment, when the blood taking operation is performed, that is, the blood box 300 is taken out, the rotating drive device 230 is driven to rotate the carrier disc 220, so that the storage position corresponding to the blood box 300 to be taken out is opposite to the access opening 101, then the opening and closing door 110 is opened, the blood box 300 is pushed out from the storage position to the access opening 101 by the pushing device 240, the pushing device 240 is reset after the pushing is completed, then the blood box 300 at the access opening 101 is taken away by the operator, and finally the opening and closing door 110 is closed. When the blood box 300 is stored, the rotating drive device 230 is driven to rotate the carrier disc 220, so that the empty storage position is opposite to the access opening 101, then the opening and closing door 110 is opened, the blood box 300 is inserted into the storage position from the access opening 101 by the operator, the blood box 300 is limited by the limiting assembly, and finally the opening and closing door 110 is closed to complete the blood storage operation.

[0050] The automatic three-dimensional blood bank with the above structure can perform the blood box 300 access operation only by setting a smaller access opening 101 in front of the refrigerator 100, can reduce heat exchange in the access process, reduce cold air loss of the refrigerator 100, and has low energy consumption; when the blood box 300 is taken out, the rotating drive device 230 is only needed to drive the carrier disc 220 to rotate, so that the corresponding storage position is opposite to the access opening 101, then the blood box 300 is pushed out by the pushing device 240, when the blood box 300 is stored, the rotating drive device 230 is only needed to drive the carrier disc 220 to rotate, so that the empty storage position is opposite to the access opening 101, then the blood box 300 is inserted into the storage position by the operator, the whole operation process is completed in front of the access opening 101, has high automation, the blood box 300 is convenient to access, and has high access efficiency; in addition, the storage position of the blood box 300 is defined by the limiting assembly and the carrier disc 220, and the limiting assembly can move relative to the carrier disc 220 to change the size of the storage position, so that the blood box 300 of different sizes can be stored, has wide application range, and has high practicability.

[0051] It is conceivable that, in order to facilitate installation and maintenance, the refrigerator 100 can be divided into a cabinet body 102 and a front panel 103, for example Figure 2 As shown in the figure, a cavity with a front opening is formed in the cabinet body 102, the front panel 103 is detachably arranged at the front side of the cabinet body 102, and the access opening 101 is formed on the front panel 103.

[0052] It is conceivable that, in order to ensure the stability of the blood box 300 when it is pushed out to the access opening 101, a support plate can be arranged at the front side of the access opening 101 to support the blood box 300 when it is pushed out.

[0053] The structure of the limiting assembly will be described below with reference to the drawings.

[0054] Referring to Figure 5As shown, in some embodiments of the present application, the limiting assembly includes first limiting parts 250 and second limiting parts 260, the first limiting parts 250 are provided with two, and the storage position is formed between the upper surface of the object carrier 220 and the two first limiting parts 250 and the second limiting parts 260.

[0055] Specifically, the two first limiting parts 250 of the same group are oppositely arranged along the circumference of the object carrier 220, and the two second limiting parts 260 can be adjusted in the direction of approaching or moving away from each other, so that the spacing between the two first limiting parts 250 can be changed; the two first limiting parts 250 are used to clamp the blood box 300, and in this embodiment, when the blood box 300 is stored in the storage position, the two first limiting parts 250 clamp the blood box 300 from the thickness direction of the blood box 300.

[0056] The second limiting part 260 is vertically adjustable and arranged on the upper side between the two first limiting parts 250, the bottom end of the second limiting part 260 is provided with a limiting groove 261, the limiting groove 261 is closed on the opposite sides and the upper side along the radial direction of the object carrier 220, and the limiting groove 261 is used for embedding the top of the blood box 300; by providing the limiting groove 261, the vertical displacement of the blood box 300 can be limited, and the displacement of the blood box 300 along the radial direction of the object carrier 220 can be limited, so that the blood box 300 can be prevented from moving randomly, the stability of the blood box 300 can be ensured, and the blood box 300 can be prevented from moving to a position interfering with the object carrier 220, so as to avoid affecting the rotation of the object carrier 220. In this embodiment, when the storage position is opposite to the access opening 101, the opposite sides along the radial direction of the object carrier 220 are the front and rear sides of the limiting groove 261.

[0057] In this embodiment, by providing the two first limiting parts 250 and the second limiting part 260 which can be adjusted, the storage position is formed between the upper surface of the object carrier 220, on the one hand, the blood box 300 can be limited from all directions, and the stability of the blood box 300 can be ensured, on the other hand, the first limiting part 250 and the second limiting part 260 can be adjusted to change the size of the storage position, so that it can be suitable for blood boxes 300 of different specifications, and the application range is improved.

[0058] Based on the above embodiment, it is conceivable that the movement of the first limiting part 250 can be realized by electric drive or other power drive, of course, in order to reduce the cost and avoid too complex control, other non-power driven forms can also be adopted.

[0059] For example, in some embodiments of the present application, referring to Figure 5 , Figure 7 and Figure 9As shown, the first limiting parts 250 are horizontally slidably arranged on the turntable 220, and the limiting assembly further comprises two first elastic members 270, which respectively act on the two first limiting parts 250 to enable the two first limiting parts 250 to move towards each other, and through the action of the two first elastic members 270, the two first limiting parts 250 can clamp the blood box 300; wherein the two first limiting parts 250 are respectively provided with clamping surfaces 251 and first guide surfaces 252 on the sides thereof facing each other, the clamping surfaces 251 are perpendicular to the sliding direction of the first limiting parts 250, and the clamping surfaces 251 are used to contact the side surface of the blood box 300, and the first guide surfaces 252 are located at one end of the clamping surfaces 251 away from the center of the turntable 220, and the first guide surfaces 252 of the two first limiting parts 250 extend obliquely in a direction away from each other, and are used to abut against the blood box 300 during storage of the blood box 300 in the storage position.

[0060] Specifically, when the storage position is opposite to the access opening 101, the two first limiting parts 250 are distributed left and right relative to each other, the first elastic members 270 exert elastic force on the first limiting parts 250 in the left-right direction, the clamping surfaces 251 are perpendicular to the left-right direction, and the first guide surfaces 252 are located at the front side of the clamping surfaces 251. During insertion of the blood box 300 into the storage position from the access opening 101, the blood box 300 first contacts the first guide surfaces 252 of the two first limiting parts 250, and since the first guide surfaces 252 are obliquely arranged, the blood box 300 can move along the first guide surfaces 252, thereby pushing open the two first limiting parts 250, and the two first limiting parts 250 elastically move away from each other until the blood box 300 moves to between the two clamping surfaces 251, at which time the distance between the two first limiting parts 250 no longer changes, and the two first limiting parts 250 clamp the blood box 300.

[0061] Through the above structure, during storage of the blood box 300 in the storage position, the first limiting parts 250 can be pushed open by abutting against the first guide surfaces 252, and then enter between the clamping surfaces 251 of the two first limiting parts 250, thereby being clamped by the two first limiting parts 250, without the need to additionally provide a power structure to drive the first limiting parts 250 to move, which is low in cost and convenient to operate, and the two first limiting parts 250 can elastically move, and can be suitable for blood boxes 300 of various specifications.

[0062] It can be understood that, in order to make the blood box 300 more smoothly inserted, the clamping surfaces 251 and the first guide surfaces 252 are smoothly transitioned between each other.

[0063] Reference Figure 7As shown, in some embodiments of the present application, the carrier disc 220 is provided with a mounting plate 221 on each side of the two first limiting portions 250, and the two first limiting portions 250 are provided with a first guide rod 253 on each side, the first guide rod 253 is slidably arranged in the mounting plate 221 on the corresponding side and is threadedly connected with a first limiting nut 254, the first limiting nut 254 is arranged to avoid the first guide rod 253 from being separated from the mounting plate 221, and the position of the first limiting nut 254 can be adjusted by screwing to control the travel of the first limiting portion 250; in addition, the first elastic member 270 is a first compression spring and is sleeved on the first guide rod 253, the two ends of the first compression spring abut against the first limiting portion 250 and the mounting plate 221 respectively, so as to apply an elastic pressure to the first limiting portion 250, which is simple in structure and convenient to install. In this embodiment, the first guide rods 253 are distributed left and right when the storage position is opposite to the access opening 101.

[0064] Based on the above embodiment, it is conceivable that the movement of the second limiting portion 260 can also be achieved by electric power driving or other power driving forms. Of course, in order to reduce the cost and avoid too complex control, other non-power driving forms can also be adopted.

[0065] For example, in some embodiments of the present application, referring to Figures 5 to 8 As shown, the second limiting portion 260 is vertically slidably arranged on the carrier disc 220, and the limiting assembly further comprises a second elastic member 280, the second elastic member 280 is used to apply a downward elastic force to the second limiting portion 260, so as to press the blood box 300 against the upper surface of the carrier disc 220, thereby vertically limiting the blood box 300; the pushing device 240 comprises a pushing portion 241, the pushing portion 241 is configured to: when the storage position storing the blood box 300 is opposite to the access opening 101, the pushing portion 241 can be extended forward and act on the second limiting portion 260 and the blood box 300 in sequence, so as to sequentially release the limiting of the second limiting portion 260 on the blood box 300 and move the blood box 300 towards the access opening 101, that is, the release of the limiting of the second limiting portion 260 on the blood box 300 and the forward pushing of the blood box 300 are both completed by the pushing portion 241, one device realizes two functions, and the structure is simplified.

[0066] Based on the above embodiment, in some embodiments of the present application, referring to Figure 5 and Figure 8 As shown, the second limiting portion 260 is provided with a second guide surface 262 at one end of the limiting groove 261 close to the center of the carrier disc 220, the second guide surface 262 extends upwardly and obliquely from the bottom end of the limiting groove 261 towards the center of the carrier disc 220, and the second guide surface 262 is used to abut against the pushing portion 241 when the pushing portion 241 is extended forward, so as to enable the pushing portion 241 to push the second limiting portion 260 to move upwardly and release the limiting on the blood box 300.

[0067] In this embodiment, by setting the second guide surface 262, when the blood box 300 is taken out, the storage position is opposite to the access opening 101, and the pushing part 241 can be extended forward. The pushing part 241 first abuts against the second guide surface 262, and then, through the guidance of the second guide surface 262, the pushing part 241 lifts the second limiting part 260 upward, so that the second limiting part 260 releases the limiting of the blood box 300. Then, the pushing part 241 continues to move forward until it abuts against the blood box 300, and then the blood box 300 can be pushed forward to the access opening 101.

[0068] In a further embodiment, as shown in Figure 10 , the front end of the pushing part 241 is provided with a first abutting surface 242 and a second abutting surface 243. The first abutting surface 242 extends downward and forward, and is used to abut against the second guide surface 262 to increase the contact area between the pushing part 241 and the second limiting part 260, so that the pushing part 241 can more smoothly lift the second limiting part 260. The second abutting surface 243 is vertically extended at the inclined bottom end of the first abutting surface 242, and is used to abut against the blood box 300 to ensure the area of the pushing part 241 and the blood box 300, so as to avoid the problem of stress concentration when the pushing part 241 pushes the blood box 300 forward.

[0069] In a further embodiment, referring to Figure 5 and Figure 8 , the second limiting part 260 is provided with a third guide surface 263 at one end of the limiting groove 261 away from the center of the carrier disk 220. The third guide surface 263 extends upward and away from the center of the carrier disk 220 at the bottom end of the limiting groove 261.
