[0024] In order to make the personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments.

[0025] EMBODIMENT

[0026] As Figure 1 , 2 indicated, the embodiment discloses a program cooling instrument freezing frame, which comprises a frame body 1, a moving frame and a plurality of cross rods 5.

[0027] Among them, the frame body 1 is in the shape of a cuboid or a cube; the frame body 1 is composed of two side plates, a top plate and a bottom plate arranged on the upper and lower ends of the two side plates respectively, and a back plate connecting the two side plates; so that the frame body 1 has an opening, as Figure 1 indicated.

[0028] In addition, a plurality of layers of baffle plates 8 are arranged in the frame body 1 from top to bottom, the internal space of the frame body 1 is divided into a plurality of storage grids 2 for storing freezing boxes by the baffle plates 8, and the opening on the frame body 1 is divided into the openings of the respective storage grids 2. In use, the freezing boxes can be placed in the storage grids 2 through the openings of the storage grids 2, or the freezing boxes can be taken out from the storage grids 2.

[0029] The moving frame is arranged on the frame body 1 and located on the opening side of the frame body 1. Specifically, the moving frame comprises a pull rod 4 and two side rods 3; the upper ends of the two side rods 3 penetrate the top plate of the frame body 1 upwards and are connected with the two ends of the pull rod 4 respectively. The two side rods 3 and the top plate of the frame body are gap-fitted, so that the whole moving frame can move up and down. The number of cross rods 5 is the same as that of the storage grids, and they are distributed vertically, and their two ends are connected with the two side rods 3 respectively, so that they can move up and down with the moving frame.

[0030] In addition, the frame body 1 is provided with a positioning block 7, and the two side rods 3 penetrate the positioning block 7. The positioning block 7 can make the moving frame move up and down more stably.

[0031] The position of the crossbar 5 needs to meet the following condition: In the initial state, the moving frame is in the closed position, at which time the crossbar 5 can seal the opening of each storage compartment 2, that is, one crossbar 5 closes the opening of one storage compartment 2. Figure 1 As shown; and, when the moving frame moves upward to the open position, the crossbar 5 is misaligned with the opening of the storage compartment 2, thereby opening the opening of the storage compartment 2, as shown. Figure 2 As shown. In this embodiment, when the moving frame is in the closed position, the crossbar 5 is located in the middle of the opening of the storage compartment 2. When it is necessary to open the storage compartment 2, simply lift the lifting rod 4 by hand and raise the moving frame upwards by half the height of the storage compartment 2. This takes up less space and is more convenient to open. It should be noted that when the moving frame is moved upwards to the open position, the two side rods 3 will not disengage from the positioning block 7, in order to prevent the side rods 3 from needing to be re-passed through the positioning block 7 when closing the storage compartment 2, which would cause operational inconvenience.

[0032] In addition, in order to fix the moving frame in the open position for easy access to the cryopreservation box, the cryopreservation rack of the programmable cooling device also includes a fixing component.

[0033] Specifically, the fixing assembly includes a first suction member 6 disposed on the uppermost crossbar 5, a receiving groove 10 formed on the lower surface of the top plate of the frame 1, and a second suction member 11 disposed within the receiving groove 10, such as... Figure 1 , 3 As shown.

[0034] The size of the receiving slot 10 matches the size of the uppermost horizontal bar 5. When the moving frame is raised to the open position, the uppermost horizontal bar 5 is retracted into the receiving slot 10, while the positions of the remaining horizontal bars 5 correspond one-to-one with the partitions 8. At this time, the openings of each storage compartment 2 are opened, such as... Figure 2 As shown. Simultaneously, the first suction member 6 and the second suction member 11 engage. Under the suction force of the first suction member 6 and the second suction member 11, the moving frame is fixed in the open position for easy access to the cryopreservation box. When it is necessary to close the opening of the storage compartment 2, simply press down the lifting rod 4; the first suction member 6 and the second suction member 11 will separate, and the moving frame will return to the closed position. The operation is convenient and quick.

[0035] Specifically, the first attracting member 6 and the second attracting member 11 can be implemented using magnets; or, in the first attracting member 6 and the second attracting member 11, one is a magnet and the other is an iron sheet.

[0036] In addition, a handle 9 is provided on the top plate of the frame 1 to facilitate the transfer of the frozen storage rack.

[0037] It is to be noted that all features disclosed in this specification, and / or all methods or processes disclosed in this specification, can be combined in any combination, except combinations where at least some of the features and / or steps are mutually exclusive.

[0038] In addition, the above specific embodiments are exemplary, and those skilled in the art can think of various solutions under the inspiration of the disclosure of the present application, and these solutions also belong to the disclosed range of the present application and fall within the protection scope of the present application. Those skilled in the art should understand that the specification and drawings of the present application are illustrative and do not constitute a limitation on the claims. The protection scope of the present application is defined by the claims and their equivalents.
