The inner walls on both sides of the cabinet body are symmetrically provided with vertical grooves along the center line of the cabinet body, and a lifting plate is slidably connected in the vertical groove, and a first spring is provided between the lifting plate and the vertical groove. The lifting plate is provided with a plurality of grooves for storing blood specimens, and transverse holes are symmetrically provided on both sides of the cabinet body along the center line of the cabinet body, and a prompt block is slidably connected to the transverse hole, and a marking section is provided on the prompt block. It also includes a linkage mechanism that drives the prompt block to move along the path of the transverse hole as the lifting plate rises and falls.

[0004] The above patent first requires to separate the cabinet cover and the cabinet body, put the blood specimens into the grooves one by one, and then connect the cabinet cover and the cabinet body to seal; in the process of putting in the blood specimens, as the number of blood specimens put into the cabinet body increases, the weight also increases, causing the lifting plate to gradually move downward, and the first spring is compressed; the lifting plate drives the prompt block to move outward along the path of the transverse hole through the linkage mechanism, that is, at this time the two prompt blocks move in opposite directions; when the grooves on the lifting plate are full of blood specimens, the prompt block moves outward so that the marking section moves out of the cabinet body, and when the cabinet cover and the cabinet body are connected to keep the blood specimens sealed, medical staff can directly know from the marking section on the prompt block outside the cabinet body that the cabinet body is full of blood specimens, without having to separate the cabinet cover and the cabinet body to know.

[0005] However, since some tissue structures need to be in a light-free environment, other specimens will inevitably be affected by light during the process of taking out the required specimens from the storage cabinet, which may cause damage to the specimens. Summary of the invention

[0006] The present invention provides an animal experiment tissue specimen storage device, aiming to solve the problem in the related art that in the process of taking out the required specimen, other specimens will inevitably be affected by light, which may cause damage to the specimen.

After the specimens are placed, the support mechanism is pushed into the box, and the support mechanism can fit with the open structure on the side of the box, so that the box is in a light-free environment. When taking out the specimen, the first rotating ring and the second rotating ring rotate the storage box containing the specimen to be taken out to the bottom of the opening, and then open the shielding component to take out the specimen. In the process of taking out the specimen, since the storage box is located below the opening, it can block the light at the opening and prevent light from entering the box, ensuring that the box is in a light-free environment, thereby preventing the specimen from being damaged.

The second elastic member is a spring, one end of which is fixedly connected to the box body 1, and the other end of which can be stopped by the second support frame 202. The second support frame 202 can move left and right relative to the first support frame 201. A limit plate is provided at the left end of the first support frame 201, and the limit plate can be stopped by the second support frame 202 to prevent the second support frame 202 from separating from the first support frame 201. The top of the box body 1 is also provided with an opening, and a shielding component 25 is provided at the opening.

[0037] like Figure 2 , Figure 4 and Figure 5 As shown, the rotating assembly includes a first rotating ring 3 and a second rotating ring 4.

[0038] like Figure 3 and Figure 5 As shown, the first support frame 201 and the second support frame 202 are respectively provided with circular grooves 8 at the center of the first rotating ring 3 and the second rotating ring 4, and the top of each circular groove 8 is provided with a vertically distributed card slot 9. The first positioning rod 5 is connected to the first rotating ring 3 through a first elastic member 10, and the first positioning rod 5 is provided with a stopper 11, which can be snap-fitted with the card slot 9 and can slide along the card slot 9.

[0039] like Figures 6 to 8As shown, a limit rod 15 is provided between the storage box 7 and the first positioning rod 5, and a rotating hole 13 is provided on the first positioning rod 5. One end of the limit rod 15 extends into the rotating hole 13 and slides with the rotating hole 13. A plurality of limit blocks 16 evenly distributed along its circumference are provided on the side wall of the other end of the limit rod 15. The limit blocks 16 and the limit rod 15 are elastically connected by springs. The limit blocks 16 can be received in the limit rod 15. A plurality of limit grooves 14 evenly distributed along its circumference are provided on the circumferential side of the rotating hole 13. The limit grooves 14 correspond to the limit blocks 16. Each limit block 16 can cooperate with a limit groove 14. The limit block 16 cooperates with the limit groove 14 to limit the rotation of the limit rod 15 relative to the first positioning rod 5, thereby limiting the rotation of the storage box 7.

[0040] like Figure 2 and Fig. 9 As shown, the first support frame 201 and the second support frame 202 are slidably matched with a control rod 17, and the control rod 17 can move along its axial direction and rotate around its axis. The first support frame 201 is rotatably matched with a first gear 18, and the second support frame 202 is rotatably matched with a second gear 19. The inner walls of the first rotating ring 3 and the second rotating ring 4 are both provided with tooth grooves, and the first gear 18 is meshed with the first rotating ring 3 through the tooth grooves, and the second gear 19 is meshed with the second rotating ring 4 through the tooth grooves. The first gear 18 and the second gear 19 are both sleeved on the control rod 17, and both are slidably matched with the control rod 17. The first gear 18 and the second gear 19 are both provided with a first matching groove, and the side wall of the control rod 17 is provided with two first matching keys 20 corresponding to the first matching grooves, and the two first matching keys 20 can be matched with the corresponding first matching grooves, so as to be snap-fitted with the first gear 18 and the second gear 19, and the control rod 17 can drive the first gear 18 and the second gear 19 to rotate, thereby driving the first rotating ring 3 and the second rotating ring 4 to rotate.

[0041] like Figure 2 , Figure 5 and Fig. 9As shown, the first support frame 201 is also rotatably matched with a third gear 21, which is sleeved on the control rod 17 and slidably matched with the control rod 17. The third gear 21 is provided with a second matching groove, and the side wall of the control rod 17 is provided with a second matching key corresponding to the second matching groove. The second matching key can match with the second matching groove, so that the control rod 17 can drive the third gear 21 to rotate. The first support frame 201 is also slidably matched with a driving rack 22, which is vertically distributed and meshes with the third gear 21. The rotation of the third gear 21 can drive the driving rack 22 to move up and down. The upward movement of the driving rack 22 can push the first positioning rod 5 located at the uppermost end of the first rotating ring 3 upward. The upward movement of the first positioning rod 5 can drive the storage box 7 and the second positioning rod 6 to move upward synchronously, so that the storage box 7 can be sent to the opening, which is convenient for taking out the specimens stored in the storage box 7.

[0042] like Figure 1 and Fig. 9 As shown, a grip 23 is also provided at the right end of the control rod 17, so that the staff can operate the control rod 17 conveniently. A fourth elastic member 24 is provided between the grip 23 and the first support frame 201. The fourth elastic member 24 is a spring, one end of which is fixedly connected to the grip 23 and the other end of which is connected to the first support frame 201. The fourth elastic member 24 is provided to facilitate the restoration of the control rod 17.

[0043] like Figure 6 and Fig.10 As shown, the shielding assembly 25 includes a first baffle 251 and a second baffle 252. One end of the first baffle 251 is connected to the box body 1 through a spring, and the bottom of the other end thereof is provided with a first inclined surface. One end of the second baffle 252 is connected to the box body 1 through a spring, and the bottom of the other end thereof is provided with a second inclined surface. The first baffle 251 and the second baffle 252 are symmetrically distributed, and two springs respectively apply a force to the first baffle 251 toward the second baffle 252, and apply a force to the second baffle 252 toward the first baffle 251, so that the first baffle 251 and the second baffle 252 stop against each other under the action of the spring elastic force, and a V-shaped groove is formed between the first inclined surface and the second inclined surface. A push block 26 is provided at the top of the first positioning rod 5. The top of the push block 26 has a conical protrusion. When the first positioning rod 5 moves upward, the conical protrusion can contact the V-shaped groove. When the first positioning rod 5 continues to move upward, the first positioning rod 5 can overcome the spring force to separate the first baffle 251 from the second baffle 252. At this time, the opening is opened.

[0044] According to the animal experimental tissue specimen storage device of the embodiment of the present invention, the first support frame 201 is manually pulled out of the box 1, and the specimens are placed in the storage box 7 in sequence. In the process of placing the specimens, since the first support frame 201 extends out of the box 1, the limit plate at the left end of the first support frame 201 stops with the second support frame 202, and drives the second support frame 202 to move synchronously. When the first support frame 201 moves to the rightmost end, the second support frame 202 is separated from the contact with the second elastic member. At this time, under the elastic force of the third elastic member 12, the spacing between the first rotating ring 3 and the second rotating ring 4 is at the maximum value. At this time, the limit block 16 is separated from the limit groove 14, and the storage box 7 and the first positioning rod 5 and the second positioning rod 6 can rotate relative to each other, so that the storage box 7 can always be in a vertical state under the action of gravity to prevent the specimens from falling. After the specimens are placed, the first support frame 201 is pushed into the box 1, and the first support frame 201 can fit with the open structure on the side of the box 1, so that the box 1 is in a lightless environment. At this time, the second elastic member pushes the second support plate to move to the left under the action of elastic force, thereby reducing the distance between the first rotating ring 3 and the second rotating ring 4, and the limiting rod 15 can be inserted into the rotating hole 13 as a whole, and the limiting block 16 can be snap-fitted with the limiting groove 14, thereby limiting the rotation of the storage box 7, preventing the storage box 7 from shaking during the transportation of the animal experimental tissue specimen storage device, and thereby preventing the specimen from spilling. When it is necessary to take out the specimen, first manually push the control rod 17 to move to the left and extend it into the box body 1, and the control rod 17 pushes the second support frame 202 to overcome the elastic force of the second elastic member and move away from the first support frame 201, so that the limiting block 16 is separated from the limiting groove 14, and the rotation restriction of the storage box 7 is released. The control rod 17 moves to the left so that the first matching key 20 matches the first gear 18 and the second gear 19 respectively. At this time, manually rotating the control rod 17 can drive the first gear 18 and the second gear 19 to rotate, thereby driving the first rotating ring 3 and the second rotating ring 4 to rotate, and rotate the specimen to be taken out to the bottom of the opening. At this time, pulling the control rod 17 to move right, the second support frame 202 approaches the first support frame 201 under the elastic force of the second elastic member, thereby restoring the rotation limit of the storage box 7, and the control rod 17 moves to the right so that the first matching key 20 disengages from the first gear 18 and the second gear 19, and the second matching key matches with the third gear 21, at this time, manually rotating the control rod 17, the control rod 17 drives the third gear 21 to rotate, and the third gear 21 drives the driving rack 22 to move from bottom to top, and the driving rack 22 stops with the first positioning rod 5 during the movement and drives the first positioning rod 5 to move upward, the first elastic member 10 is stretched, and the stopper 11 cooperates with the card slot 9 during the upward movement of the first positioning rod 5, thereby preventing the first positioning rod 5 from shaking.When the first positioning rod 5 moves upward until the push block 26 stops against the V-shaped groove, the first positioning rod 5 continues to move upward to push the first baffle 251 and the second baffle 252 away. At this time, the storage box 7 can extend out of the box body 1 through the opening, so that it is convenient for the staff to take out the specimens in the storage box 7. Then the control rod 17 rotates in the opposite direction to drive the rack 22 to move downward, the first elastic member 10 contracts, and the first positioning rod 5 and the second positioning rod 6 move downward under the action of the first elastic member 10 until the block 11 is separated from the slot 9. When the first positioning rod 5 and the second positioning rod 6 are separated from the contact with the first baffle 251 and the second baffle 252, the first baffle 251 and the second baffle 252 are close to each other and stop against each other under the action of the spring force, thereby closing the opening and ensuring a lightless environment in the box body 1. After the control rod 17 is released, the control rod 17 is restored under the action of the fourth elastic member 24.
