[0033] Example 1

[0034] The utility model discloses a sealed storage device for veterinary drugs used in a laboratory. Figure 1-Figure 7As shown, it includes a storage box 1, several test tube bodies 2, a turntable 6, a material taking mechanism 9 and a sealing mechanism 10. The upper side of the storage box 1 is provided with a material port 3 for placing and taking out the test tube bodies 2. A support column 4 is rotatably provided inside the storage box 1. A placing mechanism 5 is provided on the outside of the support column 4 for placing several test tube bodies 2. The placing mechanism 5 includes a placing rack 501 provided on the outside of the support column 4. The placing rack 501 is provided with several limiting openings 502 for the test tube bodies 2 to pass through. The test tube bodies 2 pass through the limiting openings 502 and are located on the inner side of the limiting openings 502. By utilizing the cooperation between the placing rack 501 and the limiting openings 502, the test tube bodies 2 can be stably placed in the interior of the storage box 1 for storage.

[0035] The turntable 6 is rotatably arranged on the upper part of the storage box 1. The bottom end of the turntable 6 is connected to the top end of the support column 4. A groove 7 is provided on one side of the turntable 6. A positioning mechanism 8 is provided in the groove 7 for positioning the rotation angle of the placement rack 501. By rotating the turntable 6, the support column 4 can be driven to rotate. The rotation of the support column 4 can drive the placement rack 501 to rotate, making it convenient to take the corresponding test tube body 2.

[0036] The material taking mechanism 9 is arranged inside the storage box 1 and is used to take out the test tube body 2 in the limit opening 502. The material taking mechanism 9 includes a threaded rod 901 rotatably arranged inside the storage box 1. The outer lower end of the threaded rod 901 is threadedly provided with a threaded sleeve 902, and the outer upper end of the threaded rod 901 is provided with a driven bevel gear 903. The material taking mechanism 9 can drive the test tube body 2 to move upward, eliminating the need for an operator to take the test tube body 2 inside the storage box 1, thereby reducing the risk of contamination of the test tube body 2.

[0037] The sealing mechanism 10 is arranged on the upper side of the storage box 1. The sealing mechanism 10 includes a discharge pipe 101 arranged on the upper side of the storage box 1, and the discharge pipe 101 is located on the outside of the material port 3. A sealing cover 102 is provided on the discharge pipe 101. The sealing mechanism 10 further improves the sealing of the storage box 1.

[0038] Among them, the placement mechanism 5 also includes a plurality of support sleeves 503 arranged at the bottom end of the placement rack 501. The number of the support sleeves 503 is consistent with the number of the limiting openings 502, and the support sleeves 503 are located directly below the limiting openings 502. The bottom end of the test tube body 2 contacts the inner bottom end of the support sleeve 503, and a notch 504 is opened on the support sleeve 503.

[0039] It should be noted that when the test tube body 2 is placed in the storage box 1 for storage, the bottom end of the test tube body 2 is passed through the limiting opening 502, and the bottom end of the test tube body 2 is brought into contact with the inner bottom end of the support sleeve 503. Then, the limiting opening 502 and the support sleeve 503 are used to allow the test tube body 2 to be stably placed in the storage box 1, and several test tube bodies 2 will not collide with each other when the placement rack 501 rotates.

[0040] The positioning mechanism 8 includes a spring 801 disposed in the groove 7. A positioning rod 802 is disposed at one end of the spring 801 away from the inner wall of the groove 7. The end of the positioning rod 802 away from the spring 801 extends through the groove 7. The end of the positioning rod 802 extending through the groove 7 is semicircular, and the vertical cross-sections of the groove 7 and the positioning rod 802 are both T-shaped.

[0041] The upper end of the storage box 1 is located on the outside of the turntable 6 and is provided with a positioning ring 11. The inner side of the positioning ring 11 is provided with several positioning holes 12. A metal block 13 is provided inside the positioning hole 12. The end of the positioning rod 802 away from the spring 801 is inserted into the corresponding positioning hole 12 and abuts against the metal block 13.

[0042] It should be noted that, as mentioned above, when the test tube body 2 is placed in the storage box 1 and needs to be taken out, the operator can rotate the turntable 6, and the rotation of the turntable 6 drives the support column 4 to rotate, and the rotation of the support column 4 drives the placement rack 501 to rotate, and the rotation of the placement rack 501 can drive the test tube body 2 to move, and when the turntable 6 rotates, it drives the positioning rod 802 to move out of the corresponding positioning port 12. At this time, the positioning rod 802 will contact the inner wall of the positioning ring 11 to squeeze the spring 801, and then as the turntable 6 continues to rotate, when the positioning ring 11 is pressed, the test tube body 2 will be moved. When the positioning rod 802 rotates to the corresponding positioning port 12, the extrusion force on the positioning rod 802 disappears, and the elastic force of the spring 801 can drive the positioning rod 802 to be reinserted into the corresponding positioning port 12. When the positioning rod 802 is inserted into the positioning port 12, it will collide with the metal block 13, thereby emitting a crisp collision sound. At this time, the test tube body 2 is just moved to the bottom of the material port 3, which makes it convenient to position the rotation angle of the placement rack 501, making it convenient to take the test tube body 2 out of the storage box 1.

[0043] The material taking mechanism 9 further includes a handle 904 rotatably arranged on the upper end of the outer side of the storage box 1. One end of the handle 904 penetrates into the interior of the storage box 1 and is provided with a driving bevel gear 905. The driving bevel gear 905 is meshed with the driven bevel gear 903. The outer side of the threaded sleeve 902 is provided with a lifting block 906 for use with the notch 504.

[0044] A guide block 14 is provided on the side of the threaded sleeve 902 away from the lifting block 906 , and a guide groove 15 is provided inside the storage box 1 . The side of the guide block 14 away from the threaded sleeve 902 penetrates into the guide groove 15 and is slidably connected to the guide groove 15 .

[0045] It should be noted that, as mentioned above, when the test tube body 2 to be taken is moved to the bottom of the material port 3, the operator can turn the handle 904, and the rotation of the handle 904 drives the active bevel gear 905 to rotate, and the rotation of the active bevel gear 905 drives the driven bevel gear 903 to rotate, and the rotation of the driven bevel gear 903 drives the threaded rod 901 to rotate. The rotation of the threaded rod 901 can drive the threaded sleeve 902 to move upward by utilizing the cooperation of the guide block 14 and the guide groove 15. The upward movement of the threaded sleeve 902 drives the lifting block 906 to move upward, and the lifting block 906 moves up into the notch 504 and continues to move along the notch 504. At this time, the lifting block 906 will push the test tube body 2 to move upward, and the operator does not need to take the test tube body 2 inside the storage box 1, thereby reducing the risk of contamination of the test tube body 2.

[0046] A transparent observation window 16 is provided on the outside of the storage box 1 , and the supporting sleeve 503 is made of a transparent material.

[0047] It should be noted that when taking the test tube body 2 inside the storage box 1, the test tube body 2 stored in the storage box 1 can be seen through the transparent observation window 16, and then the support sleeve 503 made of transparent material can be used to observe the type of test tube body 2 moving directly below the material port 3, thereby facilitating the rapid determination of the test tube body 2 that needs to be taken, thereby greatly improving the efficiency of taking the required test tube body 2.

[0048] A thread groove 17 is provided on the inner side of the discharge pipe 101 , and a connector 18 for use with the thread groove 17 is provided on the bottom side of the sealing cover 102 , and the connector 18 is threadedly connected to the thread groove 17 .

[0049] It should be noted that, as mentioned above, in the process of the lifting block 906 pushing the test tube body 2 upward, when the top end of the test tube body 2 moves to the inside of the discharge tube 101 and contacts the bottom side of the sealing cover 102, the handle 904 is stopped. At this time, the operator can rotate the sealing cover 102, and use the cooperation of the connecting head 18 and the threaded groove 17 to make the sealing cover 102 able to be removed from the discharge tube 101. Then the operator can quickly take the test tube body 2 out of the storage box 1, which greatly saves the time of taking the test tube body 2.

[0050] Working principle of Example 1: When storing test tube bodies 2, different types of test tube bodies 2 can be placed in different limiting openings 502 on the placement rack 501, thereby ensuring the stability of the sealed storage of the test tube bodies 2 in the storage box 1. At the same time, the sealing cover 102 ensures the sealing of the test tube bodies 2 during storage;

[0051] When the test tube body 2 needs to be taken out of the storage box 1 for experiment, the operator can rotate the turntable 6 to drive the support column 4 to rotate, and the rotation of the support column 4 drives the placement rack 501 to rotate, and the rotation of the placement rack 501 can drive the test tube body 2 to move, and when the turntable 6 rotates, it drives the positioning rod 802 to move out from the corresponding positioning port 12. At this time, the positioning rod 802 contacts the inner wall of the positioning ring 11 to squeeze the spring 801, and then as the turntable 6 continues to rotate, when the positioning rod 802 rotates to the corresponding positioning port 12, the squeezing force on the positioning rod 802 disappears, and the spring 801 is pressed. The elastic force of 801 can drive the positioning rod 802 to be reinserted into the corresponding positioning port 12. When the positioning rod 802 is inserted into the positioning port 12, it collides with the metal block 13, thereby making a crisp collision sound. At this time, the test tube body 2 is just moved to the bottom of the material port 3, thereby facilitating the positioning of the rotation angle of the placement rack 501. In this way, during the rotation of the test tube body 2, the type of test tube body 2 that has moved to the bottom of the material port 3 can be observed through the transparent observation window 16, thereby facilitating the rapid determination of the test tube body 2 that needs to be taken.

[0052] When the test tube body 2 to be taken is moved to the right below the material port 3, the operator can turn the handle 904 to drive the active bevel gear 905 to rotate. The active bevel gear 905 rotates and can drive the threaded rod 901 to rotate through the driven bevel gear 903. The rotation of the threaded rod 901 can drive the threaded sleeve 902 to move upward by the cooperation of the guide block 14 and the guide groove 15. The upward movement of the threaded sleeve 902 drives the lifting block 906 to move upward. The lifting block 906 moves up into the notch 504 and continues to move along the notch 504. At this time, the lifting block 906 will push the test tube body 2 to move upward. After the top of the body 2 moves to the inside of the discharge tube 101 and contacts the bottom side of the sealing cover 102, stop turning the handle 904. At this time, the operator can rotate the sealing cover 102 and use the cooperation of the connector 18 and the threaded groove 17 to remove the sealing cover 102 from the discharge tube 101. Then, the test tube body 2 can be quickly taken out of the storage box 1, which greatly reduces the amount of external air entering the storage box 1, helps to maintain the stability of the internal environment of the storage box 1, and does not require the operator to take the test tube body 2 inside the storage box 1, reducing the risk of contamination of the test tube body 2.

[0053] Example 2

[0054] The utility model discloses a sealed storage device for veterinary drugs used in a laboratory. Figure 8-Figure 9 As shown, a timer 19 is provided on one side of the upper portion of the storage box 1, and a controller 20 is provided on the outer side of the storage box 1, and the timer 19 is electrically connected to the controller 20;

[0055] It should be noted that when the operator needs to conduct an experiment on the veterinary drug in the test tube body 2 within a certain time period, the timer 19 can be used to time the experiment in advance. When the set experiment time is reached, the operator can be automatically reminded through sound or light signals to avoid missing the experiment.

[0056] Considering that veterinary drug experiments may need to be conducted multiple times, multiple time periods can be set through the timer 19. The operator can set multiple experimental time points at one time, and the timer 19 will automatically remind according to the set order and time points, thereby improving the flexibility of experimental arrangements.

[0057] Among them, the sealing cover 102 is rotatably connected to the discharge pipe 101, and a number of rubber sealing blocks 21 are arranged on the inner side of the discharge pipe 101. The rubber sealing blocks 21 are distributed in a circular array inside the discharge pipe 101. A rubber plug 22 is arranged on the bottom side of the sealing cover 102, and the outer side of the rubber plug 22 is tightly attached to the inner side of the discharge pipe 101.

[0058] It should be noted that, as mentioned above, when the lifting block 906 pushes the test tube body 2 upward, the top of the test tube body 2 passes through the rubber sealing block 21 and contacts the bottom side of the rubber plug 22. As the test tube body 2 continues to move upward, the sealing cover 102 is squeezed by the test tube body 2 to rotate, thereby automatically opening the sealing cover 102 on the discharge pipe 101. At this time, the test tube body 2 will stretch out several rubber sealing blocks 21, and several rubber sealing blocks 21 will fit with the outside of the test tube body 2. Then the operator can quickly take the test tube body 2 out of the storage box 1 without manually opening the sealing cover 102, which makes it more convenient to take out the test tube body 2. At the same time, the rubber sealing block 21 can further prevent outside air from entering the interior of the storage box 1, thereby helping to maintain the stability of the internal environment of the storage box 1.

[0059] The working principle of Example 2: When the operator needs to conduct an experiment on the veterinary drugs in the test tube body 2 within a certain time period, the timer 19 can be used to start the timing in advance. When the set experimental time is reached, the operator can be automatically reminded through sound and light signals to avoid missing the experiment, which provides convenience for the experiment. When the test tube body 2 is driven to move upward and contact the bottom side of the rubber plug 22, the sealing cover 102 can be rotated as the test tube body 2 continues to move upward, so that the sealing cover 102 on the discharge pipe 101 can be automatically opened. There is no need to manually open the sealing cover 102, which makes it more convenient to take out the test tube body 2. At the same time, several rubber sealing blocks 21 are fitted with the outside of the test tube body 2, which not only makes it more convenient to take out the test tube body 2, but also can further prevent outside air from entering the interior of the storage box 1, which helps to maintain the stability of the internal environment of the storage box 1.

[0060] The above describes an embodiment of the present invention, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make more equivalent embodiments based on the inspiration of this embodiment, all of which are protected by this embodiment.
