Technical Field

[0001] The utility model relates to the technical field of biological safety cabinets, in particular to a biological safety cabinet with a protective structure. Background Art

[0002] A biological safety cabinet is a type of laboratory equipment used to manipulate biological samples in a sterile environment. It can provide protection for the experimental environment, prevent samples from being contaminated or laboratory personnel from being exposed to harmful organisms. When using a biological safety cabinet, you need to pay attention to the operating procedures, such as correctly opening and closing the cabinet door, adjusting the airflow, etc., to ensure the best biosafety protection effect.

[0003] Existing related technologies often have the following defects: during the actual use of the biosafety cabinet, when the container for storing reagents is a straight cylindrical structure that is taller and smaller in diameter, the container may tilt or fall over during the placement of the reagents, thereby reducing the stability of the placement of the straight cylindrical container.

[0004] Therefore, the utility model provides a biosafety cabinet with a protective structure. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcoming in the prior art that it is inconvenient to stably place a straight cylindrical structure container inside the cabinet, and to propose a biological safety cabinet with a protective structure.

[0007] The effect achieved by the above components is: by rotating the screw rod, the screw rod will drive the clamping strip to move inside the limit groove. At this time, the clamping strip will move relative to the connecting frame. When the container is clamped in the position between the connecting frame and the clamping strip, the screw rod can be stopped from rotating. At this time, the container can be clamped between the clamping strip and the connecting frame.

[0029] Reference Figure 1 As shown, the utility model provides a technical solution: a biological safety cabinet with a protective structure, comprising a cabinet body 1, a cabinet door 2 is rotatably installed on the surface of the cabinet body 1, a clamping structure 3 is provided on the inner side of the cabinet body 1, and a padding structure 4 is provided on the inner side of the cabinet body 1.

[0030] The specific configuration and function of the clamping structure 3 and the padding structure 4 will be described in detail below.

[0031] Reference Figure 1-Figure 3As shown, in this embodiment, the clamping structure 3 includes a plurality of circular blocks 301 uniformly fixedly connected to both sides of the cabinet body 1. The circular blocks 301 are rotatably connected to the rotating blocks 302 inside. The surface of the rotating blocks 302 is fixedly connected to the connecting frame 303. The surface of the connecting frame 303 is provided with a limiting groove 310. The inner side of the connecting frame 303 is a V-shaped structure. The inner side of the connecting frame 303 is threadedly connected to a screw rod 306. The other end of the screw rod 306 is rotatably connected to a clamping bar 304. The clamping bar 304 is a V-shaped structure and is located inside the limiting groove 310. When the screw rod 306 is rotated, the screw rod 306 drives the clamping bar 304 to move inside the limiting groove 310. At this time, the clamping bar 304 and the connecting frame 303 will generate relative motion. When the container is clamped between the connecting frame 303 and the clamping bar 304, the screw rod 306 can be stopped, and the container can be clamped between the clamping bar 304 and the connecting frame 303. Two elastic pads 305 are glued to the inner side of the clamping strip 304. The elastic pads 305 further enhance the stability of the container's clamping and placement. Auxiliary blocks 307 are fixedly connected to the sidewalls of the connecting frame 303, and bolts 308 are threadedly connected to the inner surface of the auxiliary blocks 307. By rotating the bolts 308 within the auxiliary blocks 307, the twisted connecting frame 303 can be secured. The surface of the circular block 301 is provided with sockets 309, the dimensions of which match those of the bolts 308. Inserting the bolts 308 into the corresponding sockets 309 enhances the stability of the twisted connecting frame 303.

[0032] Reference Figure 1 and Figure 4-Figure 5 As shown, the bedding structure 4 specifically includes a storage box 45 fixedly connected to the inside of the cabinet 1. A paper roll 47 is placed inside the storage box 45, and a drawer hole 46 is formed on the bottom surface of the storage box 45. The bedding structure 4 facilitates the regular replacement of paper towels at the bottom wall of the cabinet 1. This replacement of paper towels prevents contamination of the bottom wall of the cabinet 1 by dripping liquids or reagents, further enhancing the protection of the bottom wall of the cabinet 1. Two rectangular blocks 41 are fixedly connected to the inside of the storage box 45. Limiting pins 44 are slidably connected to the inside of the rectangular blocks 41, and the lower ends of the limiting pins 44 are fixedly connected to a pressure strip 42. The limiting pins 44 slide within the rectangular blocks 41 to limit the movement direction of the pressure strip 42, thereby firmly pressing and securing the paper towels at the bottom wall of the cabinet 1. A drive rod 43 is threadedly connected to the inside of the rectangular blocks 41, and the drive rod 43 and the pressure strip 42 are internally connected in a rotational manner. The driving rod 43 is rotated, and the driving rod 43 pushes the pressing bar 42 to move downward.

[0033] The working principle is that when it is necessary to place a straight cylindrical container on the inner side of the cabinet 1, the straight cylindrical container is placed in the position between the connecting frame 303 and the clamping strip 304, and the screw rod 306 is rotated. The screw rod 306 will drive the clamping strip 304 to move inside the limiting groove 310. At this time, the clamping strip 304 will move relative to the connecting frame 303. When the container is clamped in the position between the connecting frame 303 and the clamping strip 304, the rotation of the screw rod 306 can be stopped. At this time, the clamping work of the container between the clamping strip 304 and the connecting frame 303 can be achieved. By setting the elastic pad 305, the stability of the container clamping and placement is further improved. By rotating the rotating block 302 inside the circular block 301, when After the connecting frame 303 is rotated to a position parallel to the cabinet door 2, the plane space occupied by the connecting frame 303 can be reduced, which facilitates the folding of the clamping structure 3 when not in use. At this time, the bolt 308 inside the auxiliary block 307 is rotated to fix the twisted connecting frame 303, and the bolt 308 is inserted into the inner side of the corresponding socket 309, which improves the stability of fixing the twisted connecting frame 303. By setting the clamping structure 3, the clamping and fixing of the straight cylindrical structure container on the inner side of the cabinet body 1 is facilitated, and the phenomenon that the straight cylindrical structure is easy to tip over when placed is avoided, thereby playing a protective role for the straight cylindrical structure container and increasing the protective function of the straight cylindrical structure container when it is placed.

[0034] Place the paper roll 47 on the inner side of the storage box 45, pull out the paper towels on the paper roll 47 from the inside of the extraction hole 46 on the storage box 45, and after spreading the paper towels flat on the bottom wall of the cabinet 1, rotate the drive rod 43, and the drive rod 43 will push the pressure strip 42 to move downward, wherein the limit pin 44 slides inside the rectangular block 41 to limit the moving direction of the pressure strip 42. At this time, the paper towels at the bottom wall of the cabinet 1 can be pressed and fixed, and the bottom side of the cabinet 1 can be replaced by regularly pulling out the paper towels. By setting the paving structure 4, the regular replacement of the paper towels at the bottom wall of the cabinet 1 is facilitated. By replacing the paper towels, the phenomenon of the bottom wall of the cabinet 1 being contaminated by dripping water or reagents is avoided, and the protection effect of the bottom wall of the cabinet 1 is further improved.
