Description

Technical Field

[0001] The utility model relates to the field of biotechnology, and more specifically to a constant temperature incubator for microbial strains. Background Art

[0002] When cultivating microbial strains, there are many types of strains. If each strain is cultivated alone, the efficiency is low, so multiple strains can be placed in the incubator at the same time. However, the culture medium for each strain during pre-cultivation is different, and the required space size is also different, so the space in the incubator needs to be adjusted to achieve the required conditions.

[0003] Patent No. CN214991622U discloses a biological box for cultivating microorganisms. The temperature adjustment plate can be removed by sliding it on a slide rail and installed on other levels to achieve the function of adjusting the internal height. The entire adjustment plate needs to be taken out and installed on other levels. After taking out the installation plate, it is necessary to prepare another plane for its placement, which may require additional experimental space. At the same time, the operation process may take a lot of time and labor-consuming. In addition, the number of card slots of the slide rail is limited and the distance is fixed. The space in the box cannot be flexibly utilized, resulting in a certain amount of space waste and cannot be accurately adjusted to a certain height. In addition, the temperature at the vent position is generally too high, which will cause uneven temperature and thus inaccurate observation results. Therefore, it is necessary to propose a welding device for component processing to improve and optimize it. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figures 1 to 7 As shown, the utility model provides a microbial strain constant temperature incubator, comprising a box body 1, on which a box door 2 is hingedly installed;

[0031] The limiting mechanism is fixedly installed inside the box 1;

[0032] The pushing mechanism is fixedly installed inside the box body 1 and is arranged on the front side of the limiting mechanism;

[0033] Among them, the pushing mechanism includes a bidirectional threaded rod 7 rotatably installed inside the box body 1, a hydraulic cylinder 8 is fixedly installed on the rear side of the box body 1, a toothed plate 9 is fixedly installed on the output shaft of the hydraulic cylinder 8, a gear 10 is fixedly sleeved on the outer wall of the bidirectional threaded rod 7, the gear 10 is meshed with the toothed plate 9, and two movable frames 11 are threadedly sleeved on the upper and lower outer walls of the bidirectional threaded rod 7 respectively, a fixed frame 29 is fixedly installed inside the box body 1, the bidirectional threaded rod 7 runs through the left side of the fixed frame 29, and the two movable frames 11 and the fixed frame 29 are respectively slidably installed with culture dish plates 12.

[0034] When the staff is doing the preparation work, they first move the space in the box 1 to the required state, and start the hydraulic cylinder 8, which drives the tooth plate 9 to extend, and the tooth plate 9 drives the gear 10 to rotate, thereby driving the bidirectional threaded rod 7 to rotate, so that the upper and lower movable frames 11 can move up and down, and control the distance between the three culture dish plates 12, so that the culture dish plates 12 move to the required position for cultivation to adapt to the size of the culture dish to be placed, and at the same time, they slide stably under the fixed limit of the limit rod 28, and through the interlayer cultivation of the culture dish plates 12, different strains can be cultivated multiple times, and contamination caused by complex colonies can be avoided, which affects the observation results. After the cultivation observation is completed, the culture dish plates 12 are pulled out for processing.

[0035] Through the power of the hydraulic cylinder 8, the bidirectional threaded rod 7 can drive the corresponding culture dish plate 12 to move up and down to control the limited space, so that the space capacity in the box 1 can be reasonably utilized. Compared with the traditional device, the device uses the pushing mechanism to change the placement height by moving the upper and lower culture dish plates 12 to adapt to the cultivation of different strains, and can cultivate a variety of fungi. The space of the entire box 1 can be adjusted, so that the space inside the constant temperature box is fully utilized, allowing more culture dishes to be placed in the constant temperature box, increasing the use efficiency of the constant temperature box, and by adjusting the position, it is convenient for the experimenter to observe and operate.

[0036] Among them, an electric heating box 4 is fixedly installed on the right side of the box body 1;

[0037] The heat dissipation mechanism is fixedly installed on the right side of the electric heating box 4;

[0038] The cleaning mechanism is slidably mounted on the top of the electric heating box 4 and is arranged on the lower side of the heat dissipation mechanism;

[0039] The cleaning mechanism includes an adjusting component and a limiting component. The adjusting component includes a motor 13 fixedly mounted on the front side of the electric heating box 4. A rotating shaft 14 is fixedly mounted on the output shaft of the motor 13. A driving gear 15 is provided on the outer wall fixed sleeve of the rotating shaft 14. Two pulleys 17 are fixedly mounted on the top of the electric heating box 4. The corresponding outer wall fixed sleeve of the pulley 17 is provided with a driven gear 16. The driven gear 16 is meshed with the driving gear 15. A belt 18 is wound around the two pulleys 17. A moving column 19 is fixedly mounted on the outer side of the belt 18. Two limiting plates 22 are fixedly mounted on the top of the electric heating box 4. A swing plate 20 is slidably mounted on the top of the two limiting plates 22. A sliding groove 21 is opened inside the swing plate 20. The top of the moving column 19 passes through the sliding groove 21. An L-shaped connecting plate 25 is fixedly mounted on the right end of the swing plate 20. A strong round brush 27 is fixedly mounted on the bottom of the L-shaped connecting plate 25. A collection cabinet 5 is fixedly mounted on the bottom of the electric heating box 4.

[0040] After the staff completes the cultivation observation, the electric heating wire of the electric heating box 4 continuously generates heat during operation, so a heat dissipation hole 6 is provided to dissipate heat. When dissipating heat, the filter plate 26 on the heat dissipation hole 6 will deposit dust and fine particles in the air, thereby forming a blockage, so it is necessary to start the motor 13, and the motor 13 drives the driving gear 15 to rotate, and the driving gear 15 drives the driven gear 16 to rotate, and the driven gear 16 drives the bearing of the pulley 17 to rotate, so that the belt 18 wrapped thereon rotates, and when rotating, the moving column 19 will also rotate accordingly, and the moving column 19 is stuck in the sliding groove 21 of the swing plate 20, so the swing plate 20 moves to the rear end in the periodic motion of the moving column 19 and then returns to the front end, forming a reciprocating motion, and then drives the strong round brush 27 to roll back and forth on the filter plate 26, so that the dust and some magazines thereon are swept into the collection cabinet 5 for cleaning.

[0041] Through the power of the motor 13, the moving column 19 carries the swing plate 20 to reciprocate back and forth on the electric heating box 4, so that the strong round brush 27 moves back and forth on the filter plate 26 to clean the filter plate 26, maintain the filtering efficiency, reduce energy consumption and extend the service life. Compared with the traditional device, the device uses a cleaning mechanism to repeatedly brush the filter plate 26 with a strong round brush 27 to clean the filter plate 26, remove the dirt on the filter plate 26, restore the filtering effect of the filter plate 26, and avoid blocking the heat dissipation hole 6, which will cause the heat dissipation to be unable to shorten the service life of the electric heating box 4 and increase the use cost.

[0042] The limiting assembly includes limiting grooves 23 respectively opened on the tops of the two limiting plates 22 , and limiting blocks 24 are fixedly installed on the bottoms of both ends of the swing plate 20 , and the bottom ends of the two limiting blocks 24 extend to the bottoms of the two limiting grooves 23 respectively.

[0043] The device of the utility model is provided with a limit block 24, so that the limit block 24 drives the swing plate 20 to slide on the limit block 24, ensuring that the swing plate 20 will not exceed the safety range during operation, thereby avoiding the occurrence of accidents. When the moving part moves to the extreme position, the limit block will counteract the limit groove, thereby limiting its stroke and changing the movement direction and state.

[0044] The limiting mechanism includes a limiting rod 28 fixedly installed inside the box 1, a bidirectional threaded rod 7 is arranged on the front side of the limiting rod 28, and the limiting rod 28 passes through the two movable frames 11 and the fixed frame 29 and is slidably connected to both the two movable frames 11 and the fixed frame 29.

[0045] The device of the utility model is provided with a limit rod 28, so that the two movable frames 11 remain stable when sliding up and down and limit the travel range of the moving parts, ensuring that they will not exceed the safety range, thereby ensuring the normal operation and safety of the equipment.

[0046] The heat dissipation mechanism includes three heat dissipation holes 6 and a filter plate 26 opened on the right side of the electric heating box 4 . The three heat dissipation holes 6 are in contact with the left side of the filter plate 26 . A swing plate 20 is arranged above the filter plate 26 .

[0047] The utility model device dissipates the heat generated during the operation of the electric heating box 4 by setting three heat dissipation holes 6 and the filter plate 26. If the heat cannot be dissipated in time, the internal temperature of the electric heating box 4 will rise, which may cause the device to overheat and be damaged. Heat dissipation can effectively transfer heat to the surrounding environment, keep the temperature inside the electric heating box stable, thereby protecting the normal operation of the device, and heat dissipation can help maintain the stability of the internal temperature of the device, ensuring accurate control and stability of the temperature.

[0048] A sealed glass door 3 is provided inside the box door 2 , and the height of the sealed glass door 3 is adapted to the placement height of the three culture dish plates 12 .

[0049] By making it possible to observe the bacterial species directly through the sealed glass door 3 when cultivating and observing, there is no need to open the box door 2 for observation and recording. Frequent opening of the box door 2 will also cause heat loss in the box body 1, and bacteria in the air will enter the box body 1, which will also have a certain impact on the temperature, making the culture result of the bacterial species inaccurate. Therefore, observation through the sealed glass door 3 can prevent the microorganisms from being contaminated by the outside world.

[0050] Among them, a fixing block 30 is fixedly installed on the front side of the electric heating box 4, and the fixing block 30 is rotatably connected to the rotating shaft 14.

[0051] By fixing the rotating shaft 14 to the electric heating box 4, the stable state of the rotating shaft 14 is ensured when the rotating shaft 14 rotates, and the rotating direction of the rotating shaft 14 is limited during movement, so that the whole device is stabilized to avoid affecting the work process.

[0052] The working principle and use process of this utility model:

[0053] When the staff is doing the preparation work, they first move the space in the box 1 to the required state, and start the hydraulic cylinder 8, which drives the tooth plate 9 to extend, and the tooth plate 9 drives the gear 10 to rotate, thereby driving the bidirectional threaded rod 7 to rotate, so that the upper and lower movable frames 11 can move up and down, and control the distance between the three culture dish plates 12, so that the culture dish plates 12 move to the required position for cultivation to adapt to the size of the culture dish to be placed, and at the same time, they slide stably under the fixed limit of the limit rod 28, and through the interlayer cultivation of the culture dish plates 12, different strains can be cultivated multiple times, and contamination caused by complex colonies can be avoided, which affects the observation results. After the cultivation observation is completed, the culture dish plates 12 are pulled out for processing.

[0054] After the staff completes the cultivation observation, the electric heating wire of the electric heating box 4 continuously generates heat during operation, so a heat dissipation hole 6 is provided to dissipate heat. When dissipating heat, the filter plate 26 on the heat dissipation hole 6 will deposit dust and fine particles in the air, thereby forming a blockage, so it is necessary to start the motor 13, and the motor 13 drives the driving gear 15 to rotate, and the driving gear 15 drives the driven gear 16 to rotate, and the driven gear 16 drives the bearing of the pulley 17 to rotate, so that the belt 18 wrapped thereon rotates, and when rotating, the moving column 19 will also rotate accordingly, and the moving column 19 is stuck in the sliding groove 21 of the swing plate 20, so the swing plate 20 moves to the rear end in the periodic motion of the moving column 19 and then returns to the front end, forming a reciprocating motion, and then drives the strong round brush 27 to roll back and forth on the filter plate 26, so that the dust and some magazines thereon are swept into the collection cabinet 5 for cleaning.
