The shell 1 is a prior art, and a constant temperature component is arranged inside itself, so that the shell 1 is powered by the power cord 3, so that the interior of the shell 1 can be in a constant temperature state, so that the cell derivatives placed inside can be stored at a constant temperature.

[0036] Reference Figure 3-Figure 5The inner wall of the housing 1 is provided with a push-pull assembly 4, which includes two sets of fixed blocks 41. The inner wall of the right fixed block 41 is elastically connected with a plug rod 46 through a limit spring 45. One end of the limit spring 45 is fixedly connected to the inner wall of the right fixed block 41, and the other end of the limit spring 45 is fixedly connected to the surface of the plug rod 46. The function of the limit spring 45 is to automatically reset the position of the plug rod 46 after it is pulled outward. The plug rod 46 penetrates and is slidably connected to the inner wall of the fixed block 41. The inner wall of the fixed block 41 is provided with a guide groove that fits the front end of the plug rod 46, so that the plug rod 46 can be pushed and pulled outward. When the rod 46 is pulled outward on the inner wall of the fixed block 41, the polygonal front end of the plug rod 46 will rotate on the inner wall of the fixed block 41, and a plurality of anti-slip grooves are provided on the surface of the plug rod 46 to facilitate pulling the plug rod 46. A limiting groove is provided on the right side of the top of the shielding door 2, and the plug rod 46 is plugged into the inner wall of the limiting groove of the shielding door 2. The plugging between the two fixes the position of the shielding door 2 after the bottom plate 42 is moved and unfolded, and also fixes the position of the bottom plate 42 after the shielding door 2 is closed to push the bottom plate 42 on the inner wall of the shell 1, thereby ensuring the sealing of the shell 1.

[0037] Reference Figure 3 The bottom end of the inner wall of the shell 1 is slidably connected with a bottom plate 42, and guide blocks are provided at both ends of the bottom plate 42, so that the bottom plate 42 cannot be separated from the inner wall of the shell 1, and when it moves to the front end position of the shell 1, the shielding door 2 cannot be flipped upwards. The top ends of both sides of the bottom plate 42 are hinged with hinge rods 43, and the end of the hinge rod 43 away from the bottom plate 42 is hinged with a slider 44. The hinge rod 43 is slidably connected to the inner walls of both sides of the shell 1, and cavities that fit the slider 44 are opened on both sides of the shell 1, so that the hinge rod 43 will slide on the inner wall of the shell 1 when following the movement of the slider 44, thereby hiding the hinge rod 43 and blocking the inner side of the door 2. Two groups of sliding grooves are provided on the surface, and the slider 44 is slidably connected to the inner wall of the sliding groove of the shielding door 2. The slider 44 slides on the inner wall of the shielding door 2, so that when the shielding door 2 is pulled upward, the slider 44 will move to the far right in the guide groove of the shielding door 2. At the same time, during the closing process of the shielding door 2, the slider 44 will push the hinged rod 43 and the bottom plate 42 at its bottom to move inward on the inner wall of the shell 1 until the bottom plate 42 moves to the end, and the hinged rod 43 will push the slider 44 to move downward in the guide groove of the shielding door 2. The shielding door 2 is rotatably connected between the two groups of fixed blocks 41, and a storage component 5 is provided on the surface of the bottom plate 42.

[0038] Reference Figure 6-Figure 7The storage component 5 includes a fixed frame 51, which is fixedly connected to the top of the outer wall of the bottom plate 42, one end of the return spring 54 is fixedly connected to the inner wall of the moving seat 53, and the other end of the return spring 54 is fixedly connected to the outer side wall of the moving plate 55. The function of the return spring 54 is that when the moving plate 55 is squeezed by the movement of the positioning plate 52, the moving plate 55 will move on the inner wall of the moving seat 53, and the return spring 54 will be elastically compressed until the contact is cancelled. The moving plate 55 will be elastically acted upon by the return spring 54 to restore it to its initial position, and the moving plate 55 is slidably connected to the inner wall of the moving seat 53, and the right outer wall of the moving plate 55 contacts the outer wall of the positioning plate 52. The contact between the two causes the moving plate 55 to be squeezed by the positioning plate 52 to move on the inner wall of the moving seat 53, thereby adjusting according to the culture dishes or test tubes of cell derivatives of different heights.

[0039] Reference Figure 6-Figure 7 The inner wall of the fixed frame 51 is provided with multiple groups of guide grooves, and the inner wall of the guide groove of the fixed frame 51 is slidably connected with a positioning plate 52. The positioning plate 52 is switched and moved in the multiple groups of guide grooves on the inner wall of the fixed frame 51, so that the placement space on both sides can be adjusted according to culture dishes or test tubes of different heights, and different cell derivatives can also be separated and classified for placement. The inner side wall of the fixed frame 51 is slidably connected with a moving seat 53. The moving seat 53 can only move up and down on the inner side wall of the fixed frame 51 and cannot be separated from its inner wall, thereby providing support for the moving plate 55. The inner wall of the moving seat 53 is elastically connected with the moving plate 55 through a reset spring 54. The moving seat 53 The inner wall of the fixed frame 51 is elastically connected with an insert block 57 through a connecting spring 56, one end of the connecting spring 56 is fixedly connected to the right outer wall of the insert block 57, and the other end of the connecting spring 56 is fixedly connected to the inner wall of the movable seat 53. The connecting spring 56 functions to automatically reset the position of the insert block 57 after it is moved. The insert block 57 is slidably connected to the inner wall of the movable seat 53, and a slot is provided on the inner side wall of the fixed frame 51. The insert block 57 is plugged into the inner wall of the slot. The plugging between the two fixes the movable seat 53 at multiple positions of the inner wall of the fixed frame 51, so that the height can be adjusted according to the culture dishes or test tubes of different heights for partition placement.

[0040] Working principle: When the storage device for preparing cell derivatives is working, the shielding door 2 connected by two sets of fixed blocks 41 at the top of the shell 1 contacts the surface of the shell 1, and the inside of the shell 1 is sealed by a sealing ring. The shell 1 is powered by a power cord 3, and the internal constant temperature component is used to maintain a constant temperature inside the shell 1 to preserve cell derivatives.

[0041] The limiting spring 45 in the right fixed block 41 elastically connects the plug rod 46, and the plug rod 46 passes through and is slidably connected to the inner wall of the fixed block 41. When the shielding door 2 needs to be opened, the plug rod 46 can be pulled out to make its bottom end detach from the plugging of the shielding door 2. At this time, when the shielding door 2 moves into place, the plug rod 46 will be elastically acted upon by the limiting spring 45 to be plugged into the limiting groove of the shielding door 2 to fix the position of the shielding door 2. The bottom plate 42 is slidably connected to the bottom end of the inner wall of the shell 1, and the sliding blocks 44 hinged at the other ends of the hinged rods 43 hinged at the top ends of the two sides are slidably connected to the inner wall of the sliding groove of the shielding door 2. When the shielding door 2 is opened and closed, the hinged rod 43 is driven to move by the sliding blocks 44, pushing or pulling the bottom plate 42 to move on the inner wall of the shell 1.

[0042] When placing cell derivatives, the bottom plate 42 will be pushed outwards as the shielding door 2 is opened, and will drive the fixed frame 51 to move synchronously with it. By sliding the positioning plate 52 in the multiple sets of guide grooves on the inner wall of the fixed frame 51, the internal space of the fixed frame 51 can be adjusted and separated and classified to accommodate the partitioned placement of cell derivative culture dishes or test tubes of different heights. At the same time, when the positioning plate 52 is switched and moved in the multiple sets of card slots, its outer wall will squeeze the moving plate 55 to move on the inner wall of the moving seat 53, and make the reset spring 54 elastically compressed. On the contrary, the other set of moving plates 55 will Under the elastic action of the corresponding return spring 54, the movable plate 55 is always kept in contact with the outer wall of the positioning plate 52. When cell derivatives are stored in test tubes, the plug block 57 can be moved on the inner wall of the movable seat 53, so that the movable seat 53 can drive the movable plate 55 to move up and down on the inner wall of the fixed frame 51. When it is adjusted to a suitable position, the plug block 57 is released and it will be affected by the elastic action of the connecting spring 56 to restore it to its initial position, so that it can be plugged into the card slot at the current position of the fixed frame 51 to fix the position of the movable seat 53 and the movable plate 55.
