Description

Technical Field

[0001] This invention belongs to the field of strain culture technology, specifically relating to a multi-position strain culture and observation device that can prevent cross-contamination. Background Technology

[0002] A strain, also known as a lineage, refers to a pure culture of the same microorganism from different sources. Every pure culture of a microorganism isolated from nature can be called a strain. With the rapid development of space technology, the cultivation and observation of space strains has become a key technology in strain culture. Space strains refer to strains that have entered space via spacecraft. They undergo mutagenesis in the unique environment of space, including high vacuum, microgravity, strong radiation, weak magnetic fields, and extreme temperature differences. This unique space environment can significantly increase the frequency and magnitude of strain mutations, creating more possibilities for subsequent breeding of superior varieties. When cultivating and observing strains, petri dishes are needed to hold the microbial strains.

[0003] Existing culture observation devices directly place multiple culture dishes containing microbial strains together for observation without separating them, which easily leads to cross-contamination. To address this, we propose a multi-position strain culture observation device that can prevent cross-contamination. Utility Model Content

[0004] The purpose of this invention is to provide a multi-placement strain culture and observation device that can prevent cross-contamination, in order to solve the problem mentioned in the background art that existing culture and observation devices directly place multiple culture dishes containing microbial strains together for observation without separating the multiple culture dishes, thus easily leading to cross-contamination.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-position bacterial strain culture and observation device that can prevent cross-contamination, comprising a base, a rotating shaft rotatably mounted on the upper surface of the base, a transparent cover fixedly mounted on the outer surface of the rotating shaft, a transparent partition frame fixedly mounted on the inner wall of the transparent cover, the transparent partition frame dividing the interior of the transparent cover into several petri dish observation areas, an opening being provided on the side of the transparent cover facing the petri dish observation area, and a transparent cover plate being slidably disposed at the opening, a supporting shell fixedly mounted inside the transparent cover at the petri dish observation area, a motor fixedly mounted on the side of the supporting shell, a bidirectional screw rotatably mounted on the inner wall of the supporting shell, the output shaft of the motor being fixedly connected to one end of the bidirectional screw, threaded plates being threadedly mounted on the outer surfaces of both threads of the bidirectional screw, a connecting plate being fixedly mounted at the end of the threaded plate, and a petri dish holder being fixedly mounted at the end of the connecting plate.

[0006] The above scheme, using a rotating shaft in conjunction with a transparent cover and a transparent partition frame, divides the interior of the transparent cover into multiple petri dish observation areas. This allows for separate observation of multiple petri dishes, effectively preventing cross-contamination. The transparent cover allows for easy opening and closing, facilitating the retrieval and storage of petri dishes. The supporting shell, with its bidirectional screw, drives the relative movement of two petri dish holders, securing the petri dishes firmly and preventing them from shaking during observation when the transparent cover is adjusted, thus improving the stability of the observation process.

[0007] In the above scheme, it should be noted that the motor is electrically connected to an external power supply.

[0008] In a preferred embodiment, a fixed base is fixedly installed at the top of the rotating shaft. A groove is provided on the side of the fixed base, and a spring and a telescopic rod are fixedly installed on the inner wall of the groove. The ends of the spring and the telescopic rod are fixedly installed with the same locking plate. An operating handle is fixedly installed on the surface of the locking plate. A channel for the operating handle to move is provided on the surface of the fixed base. Several locking sleeves are fixedly installed on the surface of the transparent cover. The locking plate and the locking sleeves are used in conjunction with each other. Several locking sleeves are used in conjunction with several petri dish observation areas.

[0009] Using the above scheme, the fixed base is used in conjunction with spring one and the locking plate. When the locking plate moves away from the lock sleeve, the transparent cover unlocks and can rotate to change position. At this time, spring one deforms. After the transparent cover is in the correct position, the elasticity of spring one can ensure that the locking plate is quickly inserted into the lock sleeve to achieve locking. The locking structure is simple and easy to operate.

[0010] In a preferred embodiment, a sliding block is fixedly installed on the side of the transparent cover plate, and a sliding groove is provided on the inner wall of the opening of the transparent cover for the sliding block to slide. A fixing guide rod is fixedly installed on the inner wall of the sliding groove, and the sliding block is slidably installed on the outer surface of the fixing guide rod. A spring is sleeved on the outside of the fixing guide rod, and the two ends of the spring are fixedly connected to the inner wall of the sliding groove and the surface of the sliding block, respectively.

[0011] By adopting the above scheme, the sliding block can slide in the sliding groove to ensure the stable sliding of the transparent cover. The setting of the fixed guide rod can prevent the sliding block from falling out of the sliding groove when sliding, which has a good support and guidance effect. When the transparent cover is in the closed state, the spring two deforms. Therefore, after the transparent cover is unlocked, the elastic force of the spring two can be used to quickly drive the transparent cover to slide open, improving the convenience of operation and use.

[0012] In a preferred embodiment, a fixing plate is fixedly installed on the side of the transparent cover, a locking rod is slidably installed on the fixing plate, an operating plate is fixedly installed at one end of the locking rod, a spring is fixedly installed between the operating plate and the fixing plate, and a locking groove is opened on the side of the transparent cover for the other end of the locking rod to be inserted.

[0013] Using the above solution, after the transparent cover slides closed, the spring force of spring three drives the locking rod to insert into the locking groove, which can conveniently lock the position of the transparent cover. The locking structure is simple and easy to operate.

[0014] In a preferred embodiment, a plurality of fixed guide rods are fixedly installed on the inner wall of the bearing housing, and the threaded plate is slidably installed on the outer surface of the plurality of fixed guide rods.

[0015] By adopting the above scheme, the movement of the threaded plate can be supported by the setting of the fixed guide rod 2, so that the threaded plate can move smoothly under the rotation of the bidirectional screw.

[0016] In a preferred embodiment, the inner wall of the culture dish holder is covered with an anti-slip pad, and two anti-slip pads on the support shell are arranged opposite each other.

[0017] By adopting the above solution, the anti-slip pads can provide a fixed and anti-slip effect when the culture dish is fixed and tightened, thus improving the fixation effect.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This multi-position bacterial culture and observation device, which can prevent cross-contamination, is used in conjunction with a rotating shaft, a transparent cover, and a transparent partition frame. The transparent partition frame divides the inside of the transparent cover into multiple observation areas for culture dishes, enabling separate observation of multiple culture dishes and effectively preventing cross-contamination. The transparent cover can be easily opened and closed, making it convenient to take out and store culture dishes.

[0020] This multi-position bacterial culture and observation device, which prevents cross-contamination, uses a supporting shell and a bidirectional screw to drive the relative movement of two culture dish holders, thereby fixing the culture dishes in place. This ensures that the culture dishes will not shake when the transparent protective cover is adjusted during the observation process, improving the stability of the usage effect.

[0030] By using the rotating shaft 2 in conjunction with the transparent cover 3 and the transparent partition frame 4, the interior of the transparent cover 3 is divided into multiple petri dish observation areas using the transparent partition frame 4. This allows for separate observation of multiple petri dishes, effectively preventing cross-contamination. The transparent cover 5 allows for easy opening and closing, facilitating the retrieval and storage of petri dishes. The supporting shell 6, along with the rotation of the bidirectional screw 8, drives the relative movement of the two petri dish holders 11, thereby securing the petri dishes and ensuring that they do not shake when the transparent cover 3 is adjusted during observation, thus improving the stability of the usage.

[0031] A fixed base 12 is fixedly installed at the top of the rotating shaft 2. A groove is provided on the side of the fixed base 12, and a spring 13 and a telescopic rod 16 are fixedly installed on the inner wall of the groove. The same locking plate 14 is fixedly installed at the ends of the spring 13 and the telescopic rod 16. An operating handle 15 is fixedly installed on the surface of the locking plate 14. A channel for the operation handle 15 to move is provided on the surface of the fixed base 12. Several locking sleeves 17 are fixedly installed on the surface of the transparent cover 3. The locking plate 14 and the locking sleeves 17 are used together. Several locking sleeves 17 are used in conjunction with several petri dish observation areas. The fixed base 12 is used in conjunction with the spring 13 and the locking plate 14. When the locking plate 14 moves away from the locking sleeve 17, the transparent cover 3 is unlocked and can rotate to change its position. At this time, the spring 13 deforms. After the transparent cover 3 is in the correct position, the elastic force of the spring 13 can ensure that the locking plate 14 is quickly inserted into the locking sleeve 17 to achieve locking. The locking structure is simple and easy to operate.

[0032] A sliding block 18 is fixedly installed on the side of the transparent cover 5. The inner wall of the opening of the transparent cover 3 is provided with a sliding groove for the sliding block 18 to slide. A fixed guide rod 19 is fixedly installed on the inner wall of the sliding groove. The sliding block 18 is slidably installed on the outer surface of the fixed guide rod 19. A spring 20 is sleeved on the outside of the fixed guide rod 19. The two ends of the spring 20 are fixedly connected to the inner wall of the sliding groove and the surface of the sliding block 18, respectively. By sliding the sliding block 18 in the sliding groove, the stable sliding of the transparent cover 5 can be ensured. The setting of the fixed guide rod 19 can prevent the sliding block 18 from falling out of the sliding groove when sliding, which has a good support and guidance effect. When the transparent cover 5 is in the closed state, the spring 20 deforms. Therefore, after the transparent cover 5 is unlocked, the elasticity of the spring 20 can be used to quickly drive the transparent cover 5 to slide open, improving the convenience of operation and use.

[0033] A fixing plate 21 is fixedly installed on the side of the transparent cover 5. A locking rod 22 is slidably installed on the fixing plate 21. An operating plate 23 is fixedly installed on one end of the locking rod 22. A spring 3 24 is fixedly installed between the operating plate 23 and the fixing plate 21. A locking groove is opened on the side of the transparent cover 3 for the other end of the locking rod 22 to be inserted. After the transparent cover 5 is slid closed, the spring force of the spring 3 24 drives the locking rod 22 to be inserted into the locking groove, which can realize convenient locking of the position of the transparent cover 5. The locking structure is simple and easy to operate.

[0034] Several fixed guide rods 25 are fixedly installed on the inner wall of the bearing housing 6. The threaded plate 9 is slidably installed on the outer surface of the several fixed guide rods 25. The fixed guide rods 25 can support the movement of the threaded plate 9, so that the threaded plate 9 can move smoothly under the rotation of the bidirectional screw 8.

[0035] The inner wall of the petri dish holder 11 is covered with anti-slip pads 26. Two anti-slip pads 26 on the support shell 6 are arranged opposite each other. The anti-slip pads 26 can provide a fixed and anti-slip effect when the petri dish is fixed and clamped, thus improving the fixation effect.

[0036] In use, pulling the operating plate 23 causes the locking lever 22 to move and disengage from the locking groove. At this time, the transparent cover 5 unlocks and quickly moves upward and unfolds under the elastic force of the second spring 20. The culture dish is then placed on the surface of the supporting housing 6 and positioned between the two culture dish holders 11. The motor 7 is started to drive the bidirectional screw 8 to rotate, which in turn drives the two threaded plates 9 to move relative to the two culture dish holders 11 through the connecting plate 10, thus fixing and clamping the culture dish. Then, the transparent cover 5 is pushed downward, and the operating plate 23 is pulled to cause the locking lever 22 to move and misalign with the transparent cover 3. At this time, the third spring 24 deforms, and the transparent cover... After the plate 5 is fully closed by sliding, release the operating plate 23. At this time, the elastic force of the spring 24 will drive the locking rod 22 to insert into the locking groove, thereby locking the transparent cover 5. Then, the petri dish can be observed through the transparent cover 5 and the transparent cover 3. When it is necessary to rotate and adjust the position of the transparent cover 3, hold the operating handle 15 to drive the locking plate 14 to move away from the locking sleeve 17. At this time, the spring 13 deforms and the transparent cover 3 is unlocked. Rotate the transparent cover 3 until the next locking sleeve 17 is aligned with the locking plate 14. At this time, release the operating handle 15, and use the elastic force of the spring 13 to drive the locking plate 14 to reset and insert into the locking sleeve 17, thereby locking the transparent cover 3.
