At the same time, the constant temperature incubator can accurately stabilize and provide a stable environment, thereby improving the reliability of experimental results, and it has a wide range of applications.
[0003] During the use of a thermostat, gaps can easily form between the sealing gasket and the thermostat after prolonged use, resulting in an incomplete seal. This can affect the internal environment of the thermostat and compromise the stable development of the culture medium, leading to deviations in experimental results. To address these issues, a thermostat with good sealing performance is urgently needed. Utility Model Content
[0004] The purpose of this invention is to solve the problem that during the use of a constant temperature incubator, gaps easily form between the sealing gasket and the incubator after prolonged use, resulting in poor sealing of the incubator and affecting the internal environment of the incubator. This can lead to deviations in experimental results due to the inability to ensure stable development of the culture medium. Therefore, this invention proposes a culture medium constant temperature device with good sealing performance.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a culture medium constant temperature device with good sealing effect, including a constant temperature box, a fixing frame fixedly connected to the top of the constant temperature box, a sealing component provided at the top of the constant temperature box, and a fixing component provided on the top surface of the sealing component;
[0006] The sealing assembly includes a top plate, a first pressure plate slidably connected inside the top plate, an extrusion block fixedly connected to the outside of the first pressure plate, a slide plate slidably connected to the top plate through a groove opened on its bottom surface, a second pressure plate fixedly connected to the bottom end of the slide plate, and a rubber cover provided on the bottom surface of the top plate.
[0007] As a further description of the above technical solution:
[0008] A spring is fixedly connected to one side of the skateboard, and the other end of the spring is fixedly connected to the top plate.
[0009] As a further description of the above technical solution:
[0010] A threaded sleeve is fixedly connected to the top surface of the first pressure plate, and one side of the extrusion block is in contact with the second pressure plate with the contact surface being an inclined surface.
[0011] As a further description of the above technical solution:
[0012] The first pressure plate, the extrusion block, and the second pressure plate are all located inside the rubber cover.
[0013] As a further description of the above technical solution:
[0014] The fixing component includes a protective cover, an insert block is slidably connected inside the protective cover, a rack is fixedly connected to one end of the insert block, and the bottom end of the protective cover is fixedly connected to the top plate.
[0015] As a further description of the above technical solution:
[0016] The protective cover is rotatably connected to a rotating rod through a through hole inside it. A gear is fixedly connected to the bottom end of the rotating rod, and one side of the gear meshes with a rack.
[0017] As a further description of the above technical solution:
[0018] A threaded rod is fixedly connected to the bottom end of the gear, and the threaded rod is rotatably connected to it through a through hole opened on the top surface of the top plate.
[0019] As a further description of the above technical solution:
[0020] The threaded rod is threadedly connected to the threaded sleeve, and the insert block is slidably connected to it through a slot opened in the fixing frame.
[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0022] In this invention, a second pressure plate is provided inside. After the culture medium is placed into the incubator, the top plate is placed on the top surface of the incubator, and the rubber cover is placed into the groove on the top surface of the incubator. The first pressure plate moves downward, thereby driving the second pressure plate to move to both sides and compress the rubber cover. At the same time, the first pressure plate can also compress the bottom surface of the rubber cover, so that the rubber cover can fully fit into the groove on the top surface of the incubator. Through this design, when sealing the incubator, the rubber cover can fully fit into the groove on the top surface of the incubator, thereby reducing the generation of gaps and ensuring the airtightness of the incubator. This avoids unstable temperature inside the incubator due to poor sealing, which could lead to damage to the culture medium during storage.
[0023] In this invention, an insert block is provided inside. During sealing, the rotating rod drives the gear to rotate, which in turn drives the rack to move, allowing the insert block to be inserted into the fixed frame. This design achieves the goal of limiting the top plate by inserting the insert block into the fixed frame during sealing, thereby preventing misalignment during installation and ensuring the airtightness of the constant temperature chamber.

The sliding block 42 is slidably connected to the fixing frame 2 through a groove.
[0036] The specific implementation method is as follows: when sealing, the rotating rod 43 drives the gear 44 to rotate, thereby driving the rack 46 to move through the rotation of the gear 44, and causing the insert 42 to extend out, so that the insert 42 is inserted into the fixing frame 2.

The rotating rod 43 drives the threaded rod 45 to rotate, which in turn drives the gear 44 to rotate. The rotation of the gear 44 drives the rack 46 to move, causing the insert 42 to extend and insert into the fixing frame 2. The rotation of the threaded rod 45 drives the first pressure plate 33 to move downward through the threaded sleeve 32. The first pressure plate 33 drives the squeezing block 34 to move, which in turn squeezes the second pressure plate 37, causing the second pressure plate 37 to move to both sides. The second pressure plate 37 squeezes the rubber cover 38 and compresses the spring 35. At the same time, the first pressure plate 33 squeezes the bottom surface of the rubber cover 38, so that the rubber cover 38 can fully fit into the groove on the top surface of the constant temperature chamber 1.
