Description

Technical Field

[0001] This utility model relates to the field of bacterial culture bottles, specifically a sealing device for bacterial culture bottles. Background Technology

[0002] A strain culture bottle is a container used for culturing microorganisms. It is used in microbiology laboratories to cultivate microbial strains and is characterized by being non-toxic, safe, hygienic, and having good transparency and light transmittance. It can be used for liquid or solid culture of microorganisms to study their growth characteristics, metabolites, etc. Strain culture bottles play an important role in microbiological research and applications. Through proper use and management, strains can be effectively cultured and preserved, providing support for related research and production.

[0003] However, since the bacterial culture flasks need to be covered with sealing film before being sealed with a lid, the sealing film is slippery, making it inconvenient to cover with a lid. Utility Model Content

[0005] This utility model provides the following technical solution: a sealing device for a bacterial culture bottle, comprising a support frame and an upper mounting plate. A pressure rod sleeve is provided on the upper surface of the upper mounting plate, and a sealing pressure rod is provided inside the pressure rod sleeve. A magnetic pad is installed on the lower surface of the sealing pressure rod, and a suction cup is installed on the lower surface of the magnetic pad. A bottle cap drop hole is provided below the suction cup corresponding to the lower surface of the upper mounting plate. A bottle cap guide groove is provided on one side of the bottle cap drop hole, penetrating the side surface of the upper mounting plate. A sealing film roller is installed on one side of the bottle cap drop hole, located on the lower surface of the upper mounting plate, and a limiting roller is installed on the other side of the bottle cap drop hole, located on the lower surface of the upper mounting plate.

[0006] As a further improvement of this utility model: a guide rod is installed on the upper surface of the support frame, and a magnetic slider is installed on one side of the upper mounting plate inside the guide rod.

[0007] As a further improvement of this utility model: a slot is provided on the upper surface of the support frame corresponding to the position of the bottle cap drop hole, and a culture bottle is installed inside the slot.

[0008] As a further embodiment of this utility model: the magnetic pad is magnetically fixedly connected to the upper mounting plate, and the magnetic pad is fixedly connected to the suction cup and the sealing pressure rod.

[0009] As a further improvement of this utility model, the sealing film roller is rotatably connected to the upper mounting plate.

[0010] As a further improvement of this utility model, the upper mounting plate is movably connected to the guide rod via the magnetic slider.

[0011] As a further improvement of this utility model, the outer diameter of the suction cup is greater than the inner diameter of the pressure rod sleeve.

[0012] As a further improvement of this utility model, the center of the slot is on the same straight line as the center of the bottle cap hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By applying a downward force to the sealing rod, the cap presses the sealing film downward to contact the upper part of the culture bottle. With continued application of force, the cap presses against the end of the culture bottle. The cap and culture bottle are designed with a cap drop hole and a slot to ensure that the cap can accurately press and seal the sealing film on the top of the culture bottle after compression.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-5 As shown, this embodiment provides a sealing device for bacterial culture bottles, including a support frame 1 and an upper mounting plate 2. A pressure rod sleeve 202 is provided on the upper surface of the upper mounting plate 2. A sealing pressure rod 4 is provided inside the pressure rod sleeve 202. A magnetic pad 402 is installed on the lower surface of the sealing pressure rod 4. The magnetic pad 402 is magnetically fixed to the upper mounting plate 2. A suction cup 401 is installed on the lower surface of the magnetic pad 402. The outer diameter of the suction cup 401 is larger than the inner diameter of the pressure rod sleeve 202. The magnetic pad 402 is fixedly connected to the suction cup 401 and the sealing rod 4. A bottle cap drop hole 8 is provided on the lower surface of the upper mounting plate 2 below the suction cup 401. A bottle cap guide groove 5 is provided on one side of the bottle cap drop hole 8 through the side surface of the upper mounting plate 2. A sealing film roller 9 is installed on one side of the bottle cap drop hole 8 on the lower surface of the upper mounting plate 2. The sealing film roller 9 is rotatably connected to the upper mounting plate 2. A limit roller 10 is installed on the other side of the bottle cap drop hole 8 on the lower surface of the upper mounting plate 2.

[0023] like Figure 2-3 As shown, in this embodiment, a guide rod 3 is installed on the upper surface of the support frame 1, and a magnetic slider 201 is installed on one side of the upper mounting plate 2 inside the guide rod 3. The upper mounting plate 2 is movably connected to the guide rod 3 through the magnetic slider 201. A slot 6 is opened on the upper surface of the support frame 1 at the position corresponding to the bottle cap drop hole 8. A culture bottle 7 is installed inside the slot 6, and the center of the slot 6 is on the same straight line as the center of the bottle cap drop hole 8.

[0024] The working principle of this utility model is as follows: During use, the sealing caps are arranged in an array inside the cap guide groove 5. After the sealing film is installed inside the sealing film roller 9, one end of the sealing film is pulled out and moved above the limiting roller 10, leaving a certain amount of clearance. The culture bottle 7 is then placed correspondingly inside the slot 6. The upper mounting plate 2 is adjusted downwards inside the guide rod 3 using the magnetic slider 201. Finally, a cap is inserted from the end of the cap guide groove 5 inwards, causing the innermost cap to be squeezed out. After falling into the cap hole 8 and covering the outside of the sealing film, the sealing rod 4 is applied downward force, causing the cap to press the sealing film downward to contact the upper end of the culture bottle 7. Under the continuous force, the suction cup 401 is adsorbed onto the upper surface of the cap. After the force is applied, the cap is pressed against the end of the culture bottle 7, completing the sealing process. After sealing, the sealing rod 4 is pulled upward to adsorb the magnetic pad 402 into the interior of the upper mounting plate 2, which makes it easier to push the cap into the cap hole 8 later.
