Description

Technical Field

[0001] This utility model relates to the field of microbial culture technology, specifically to a device for rapid isolation and culture of microorganisms. Background Technology

[0002] Microbial culture devices for food and drug testing are specialized equipment used to detect microbial contamination in food and drugs. They are widely used in food safety testing, drug quality control, and public health. The main function of a microbial culture device is to provide a suitable growth environment for microorganisms. By controlling conditions such as temperature, humidity, and oxygen concentration, it enables target microorganisms to grow rapidly, facilitating subsequent analysis and identification.

[0003] Patent CN221940453U discloses a microbial incubator, including a box body. A circular rod is installed inside the box body. Three circular discs are vertically and equidistantly fixed to the outside of the circular rod. Six placement trays are fixedly installed in a ring at the upper end of each circular disc. Three rectangular slots are formed at the upper end of each placement tray. Clamping components are installed inside each rectangular slot. The clamping components include guide plates, which are located inside the placement trays. Three return springs are fixedly installed outside the guide plates, located inside the rectangular slots. A vertical block is fixedly installed at one end of each return spring. Limiting blocks are fixedly installed on the inner walls of both sides of the rectangular slots. A movable rod is movably installed between two of the limiting blocks. Clamping claws are sleeved on the outside of the movable rod. This microbial incubator facilitates the clamping and placement of culture dishes.

[0004] While the aforementioned existing technology solves the problem of petri dish placement and positioning through its clamping components, it still has certain defects and shortcomings in practical use. For example, when the petri dish is placed between the three clamping claws, the claws need to expand outwards. After the dish is fully placed in the placement tray, the elastic force provided by the return spring allows the clamping claws to hold and position the petri dish. However, the clamping claws apply a certain amount of pressure to the petri dish. This design may lead to the following problems in actual operation: on the one hand, operators need to apply considerable force when lifting the petri dish upwards, which may easily cause their hands to hit the upper disc due to excessive force; on the other hand, due to the large vibration or shaking that may occur during the up-and-down pulling process, the culture medium inside the petri dish is prone to spillage, contaminating the incubator environment and even causing cross-contamination of other culture samples. In addition, there is still room for improvement in terms of improving operational efficiency and reducing the risk of misoperation. Therefore, we propose a rapid microbial isolation and culture device. Utility Model Content

[0005] The purpose of this invention is to provide a device for rapid isolation and culture of microorganisms to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The rapid isolation and culture device for microorganisms includes an incubator body, which provides the environment required for microbial culture and is existing technology, so it will not be described in detail here. The front side of the incubator body is hinged with a movable door, which is used to open and close the incubator to facilitate the placement or removal of culture dishes by the staff. The bottom of the incubator body is equipped with a controller, which is used to control the temperature, humidity and other parameters inside the incubator to provide suitable culture conditions for microorganisms.

[0008] A rotating vertical rod is rotatably connected between the upper and lower sides of the inner wall of the incubator body and at the middle position. The rotating vertical rod is used to support the disc and provide a rotation axis, so that the disc can rotate flexibly and the placement position of the culture dish can be adjusted. The outer wall of the rotating vertical rod is provided with multiple discs arranged at equal intervals in the upper and lower directions. The discs can be arranged at equal intervals in the upper and lower directions to make efficient use of the space inside the incubator.

[0009] The top of the disc has multiple circular placement slots arranged in a ring array. These slots are used to place the culture dishes and prevent them from tipping over during operation. The culture dishes are placed inside the circular placement slots. The inner wall of the circular placement slots is provided with fixing blocks to provide support for the culture dishes and further fix their position to ensure stability. The outer wall of the disc has multiple U-shaped slots arranged in a ring array. These U-shaped slots cooperate with positioning components to help fix the position of the culture dishes.

[0010] The U-shaped groove is equipped with a positioning component for positioning the culture dish. The positioning component includes a fixed vertical plate fixedly connected between the two sides of the inner wall of the U-shaped groove. The fixed vertical plate serves as a support structure and is used to connect a rectangular movable rod and a spring. A rectangular movable rod is provided through the side of the fixed vertical plate. The rectangular movable rod is used to drive the V-shaped clamping block to move, thereby clamping or releasing the culture dish. One end of the rectangular movable rod passes through the inner wall of the U-shaped groove and is fixedly connected to the V-shaped clamping block, which is used to cooperate with the fixed block to clamp the culture dish. A spring is sleeved on the outer side of the rectangular movable rod. The spring is used to provide clamping force so that the V-shaped clamping block can firmly clamp the culture dish.

[0011] Preferably, the V-shaped clamping block is located in the circular placement groove, and the culture dish is located between the fixing block and the V-shaped clamping block. The fixing block and the V-shaped clamping block together fix the culture dish.

[0012] Preferably, the fixing block has a V-shaped groove on the side near the V-shaped clamping block. The V-shaped groove is used to cooperate with the V-shaped clamping block to make the clamping of the culture dish more stable and prevent the culture dish from sliding.

[0013] Preferably, the concave surface of the V-shaped clamping block is provided with a first rubber pad, which is used to reduce direct compression of the culture dish during clamping and avoid damage to the culture dish. The concave surface of the V-shaped groove is provided with a second rubber pad, which cooperates with the first rubber pad to provide flexible fixation for the culture dish.

[0014] Preferably, the inner wall of the circular placement groove is provided with a receiving groove. When the diameter of the placed culture dish is large, the V-shaped clamping block can be moved into the receiving groove to increase the movable range of the V-shaped clamping block, thereby improving the applicability of the rapid separation culture device. A rectangular hole is provided in the disc and located between the receiving groove and the U-shaped groove. The rectangular hole is used for the rectangular movable rod and spring to pass through and move.

[0015] Preferably, both the rectangular movable rod and the spring pass through the rectangular hole, and the two ends of the spring abut against the opposite sides of the V-shaped clamping block and the fixed vertical plate, respectively, so that the spring can provide stable elastic force when clamping or releasing the culture dish.

[0016] Preferably, the outer end of the rectangular movable rod is rotatably connected to a pull ring, which is used by the operator to move the V-shaped clamping block by pulling, so as to facilitate the operator to quickly place or remove the culture dish.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This rapid microbial isolation and culture device uses a V-shaped clamping block, a fixing block, and a spring to flexibly fix the culture dish by utilizing the elasticity of the spring. When taking the culture dish out or putting it in, simply pull the rectangular movable rod outward to release the positioning of the culture dish, which improves the convenience of operation. At the same time, the first and second rubber pads further buffer the fixing force and protect the culture dish from damage.

[0019] 2. This rapid microbial isolation and culture device significantly reduces the spillage of culture medium caused by shaking or vibration during the extraction or placement of culture dishes by optimizing the fixation method of the culture dishes. In particular, the structural design of the V-shaped clamping block and fixing block combined with the V-shaped groove further improves the stability of the culture dishes and effectively avoids the risk of cross-contamination inside the incubator, thereby improving the reliability of the culture environment and the accuracy of sample detection.

[0020] 3. This rapid microbial isolation and culture device achieves flexible operation of the clamping mechanism through the pull ring connected to the outer end of the rectangular movable rod, avoiding hand impact or other accidental injuries that may be caused by excessive manual force in traditional technology. At the same time, the fixed design of the circular placement groove can greatly reduce the risk of the culture dish sliding or tipping over, enhancing the safety of operation.

[0021] 4. The rapid microbial isolation and culture device has a storage tank on the inner wall of the circular placement tank, which provides space for the V-shaped clamping block to move. This allows the device to adapt to culture dishes of different diameters. When the diameter of the culture dish is large, the V-shaped clamping block can be moved into the storage tank, expanding the applicability of the device and meeting the flexibility of different experimental needs.

[0029] Please see Figures 1-4This utility model provides a technical solution:

[0030] The rapid isolation and culture device for microorganisms includes an incubator body 1, which provides the environment required for microbial culture and is existing technology, so it will not be described in detail here. The incubator body 1 has a hinged door 2 on the front side, which is used to open and close the incubator to facilitate the placement or removal of culture dishes 8 by staff. The bottom of the incubator body 1 is equipped with a controller 3, which is used to control the temperature, humidity and other parameters inside the incubator to provide suitable culture conditions for microorganisms.

[0031] A rotating vertical rod 4 is rotatably connected between the upper and lower sides of the inner wall of the incubator body 1 and at the middle position. The rotating vertical rod 4 is used to support the disc 5 and provide a rotation axis, so that the disc 5 can rotate flexibly and the placement position of the culture dish 8 can be adjusted. The outer wall of the rotating vertical rod 4 is provided with multiple discs 5 arranged at equal intervals in the upper and lower directions. The discs 5 can be arranged at equal intervals in the upper and lower directions to make efficient use of the space inside the incubator.

[0032] The top of the disc 5 has multiple circular placement slots 50 arranged in a ring array. The circular placement slots 50 are used to place the culture dish 8 to prevent it from tipping over during operation. The culture dish 8 is placed in the circular placement slot 50. The inner wall of the circular placement slot 50 is provided with a fixing block 6. The fixing block 6 is used to provide support for the culture dish 8, further fix the position of the culture dish 8, and ensure stability. The outer wall of the disc 5 has multiple U-shaped slots 51 arranged in a ring array. The U-shaped slots 51 cooperate with the positioning member 7 to help fix the position of the culture dish 8.

[0033] A positioning component 7 is provided at the U-shaped groove 51 for positioning the culture dish 8. The positioning component 7 includes a fixed vertical plate 70 fixedly connected between the two sides of the inner wall of the U-shaped groove 51. The fixed vertical plate 70 serves as a support structure for connecting a rectangular movable rod 71 and a spring 73. The rectangular movable rod 71 is provided through the side of the fixed vertical plate 70. The rectangular movable rod 71 is used to drive the V-shaped clamping block 72 to move, thereby clamping or releasing the culture dish 8. One end of the rectangular movable rod 71 passes through the inner wall of the U-shaped groove 51 and is fixedly connected to the V-shaped clamping block 72 for cooperating with the fixed stop block 6 to clamp the culture dish 8. A spring 73 is sleeved on the outer side of the rectangular movable rod 71. The spring 73 is used to provide clamping force so that the V-shaped clamping block 72 can firmly clamp the culture dish 8.

[0034] In this embodiment, the V-shaped clamping block 72 is located in the circular placement groove 50, and the culture dish 8 is located between the fixing block 6 and the V-shaped clamping block 72. The fixing block 6 and the V-shaped clamping block 72 together fix the culture dish 8.

[0035] Specifically, a V-shaped groove 60 is provided on the side of the fixing block 6 near the V-shaped clamping block 72. The V-shaped groove 60 is used to cooperate with the V-shaped clamping block 72 to make the clamping of the culture dish 8 more stable and to prevent the culture dish from sliding.

[0036] Furthermore, the concave surface of the V-shaped clamping block 72 is provided with a first rubber pad 74, which is used to reduce the direct compression of the culture dish 8 during the clamping process and avoid damage to the culture dish. The concave surface of the V-shaped groove 60 is provided with a second rubber pad 9, which cooperates with the first rubber pad 74 to provide flexible fixation for the culture dish 8.

[0037] Furthermore, the inner wall of the circular placement groove 50 is provided with a storage groove 52. When the diameter of the placed culture dish 8 is large, the V-shaped clamping block 72 can be moved into the storage groove 52 to increase the movable range of the V-shaped clamping block 72, thereby improving the applicability of the rapid separation culture device. A rectangular hole 53 is provided in the disc 5 at a position between the storage groove 52 and the U-shaped groove 51. The rectangular hole 53 is used for the rectangular movable rod 71 and the spring 73 to pass through and move.

[0038] Furthermore, both the rectangular movable rod 71 and the spring 73 pass through the rectangular hole 53. The two ends of the spring 73 abut against the opposite sides of the V-shaped clamping block 72 and the fixed vertical plate 70, respectively. The spring 73 can provide stable elastic force when clamping or releasing the culture dish 8.

[0039] Furthermore, a pull ring 75 is rotatably connected to the outer end of the rectangular movable rod 71. The pull ring 75 is used by the staff to move the V-shaped clamping block 72 by pulling, so that the staff can quickly place or take out the culture dish 8.

[0040] In this embodiment of the rapid microbial isolation and culture device, first open the movable door 2 of the incubator body 1. Before placing the culture dish 8 inside, adjust the temperature, humidity, and other parameters inside the incubator using the controller 3 to provide a suitable environment for microbial growth. During operation, pull the pull ring 75 outward to move the V-shaped clamping block 72 away from the fixed stop block 6, and place the culture dish 8 stably in the circular placement groove 50 on the top of the disc 5. The circular placement groove 50 can stabilize the culture dish 8 and prevent it from sliding or tipping over. At the same time, the fixed stop block 6 and the V-shaped clamping block 72 are held in place by the action of the spring 73. The culture dish 8 is flexibly fixed to ensure its stability and prevent damage. After placement, the pull ring 75 is released, and the spring 73 will cause the V-shaped clamping block 72 to contact and fix the culture dish 8. The first rubber pad 74 and the second rubber pad 9 further buffer the clamping force to prevent damage to the culture dish 8. After all the culture dishes 8 are placed, the movable door 2 is closed to start the culture process. After the culture is completed, the disc 5 is rotated to a position that is easy to pick up and put down. By pulling the pull ring 75, the fixation of the V-shaped clamping block 72 on the culture dish 8 is temporarily released, and the culture dish 8 is smoothly taken out from the circular placement slot 50.
