Description

Technical Field

[0001] The utility model relates to the technical field of microorganism culture, and particularly relates to a screening device for bacillus Background Art

[0002] The screening device for bacillus is a device for culturing and screening bacillus. A culture dish is arranged inside it. The culture dish is used to hold a culture medium for culturing strains, and it is composed of a flat disc-shaped bottom and an upper cover. The existing culture dish has the following problems in actual use. First, it shakes, resulting in the culture dish tilting or falling, affecting the operation efficiency of experimental personnel. Second, when freely placed on the ground or a platform, it is easy to move or shake due to collision. In this regard, the patent document CN220116501U discloses a rapid screening culture dish for bacillus, which can solve the existing problems of shaking or falling, but still has the following problems: it can only fix a single-size culture dish and cannot fix multiple culture dishes with various outer diameter size specifications at the same time, so the experimental efficiency is low.

[0026] See Figures 1-4 As shown, a bacillus screening device includes an incubator 1, which is provided with a fixed seat on one side, an openable door on the top, and a petri dish 2 inside;

[0027] The petri dish 2 is fixed in the incubator 1 through a fixed bracket 3; the fixed bracket 3 includes: a motor 31, fixed in the incubator 1;

[0028] A first rotating shaft 33, rotatably connected to the incubator 1 and driven to rotate by the motor 31;

A first clamping groove 341 is provided on the inner side thereof for cooperating with the second clamping groove 351 to fix the culture dish 2.

[0031] An adjusting assembly is arranged in the first clamping groove 341 and the second clamping groove 351 for adjusting the clamping distance. In this embodiment, adjusting assemblies are provided in both the first clamping groove 341 and the second clamping groove 351, and the fine adjustment of the clamping distance between the fixed clip 35 and the adjusting clip 34 is realized by respectively adjusting the adjusting assemblies provided on the first clamping groove 341 and the second clamping groove 351.

[0032] In a specific implementation, both ends of the first rotating shaft 33 are round shafts. The right end is connected to the output shaft of the motor 31 through a coupling, and the left end is rotatably connected to the left side wall of the culture dish 2 through a bearing. A bearing seat is provided near the right end in the middle as another supporting end. External threads are machined on the middle part of the first rotating shaft 33, and a threaded hole 342 is machined on the adjusting clip 34. The adjusting clip 34 is connected to the first rotating shaft 33 through the threaded hole 342, and the adjusting clip 34 can be moved along the axial direction of the first rotating shaft 33 by rotating the first rotating shaft 33. The aperture of the through hole 352 on the fixed clip 35 is larger than the outer diameter of the first rotating shaft 33, so that the rotation of the first rotating shaft 33 does not interfere with the fixed clip 35. The first rotating shaft 33 passes through the fixed clip 35 and is in threaded cooperation with the adjusting clip 34. The fixed clip 35 and the adjusting clip 34 are symmetrically arranged in groups, and multiple groups are arranged along the axial direction of the first rotating shaft 33.

[0033] When using this bacillus screening device to fix the culture dish 2, first make the outer wall of the culture dish 2 fit with the second clamping groove 351 on the fixed clip 35, then start the motor 31 to drive the first rotating shaft 33 to rotate. Under the action of the screw pair, a plurality of adjusting clips 34 move relative to the first rotating shaft 33 at the same time. The first clamping groove 341 and the second clamping groove 351 approach each other and clamp the culture dishes 2 in the same column. Finally, by adjusting the adjusting assembly, the problem of inconsistent outer diameters of the culture dishes 2 caused by manufacturing errors is offset, so that the culture dishes 2 can all be fixed well. In addition, when the sizes of the culture dishes 2 to be placed are different, first adjust the adjusting assembly to move it inward, then put the culture dish 2 in, and then drive the motor 31 to rotate to reduce the distance between the adjusting clip 34 and the fixed clip 35, thereby clamping the culture dish 2, so as to realize the clamping of culture dishes 2 of different sizes and specifications.

[0034] See Figure 2As shown, in a specific embodiment, the adjustment assembly includes an adjustment member 36 and an adjustment bolt 37. The adjustment member 36 is disposed in the first clamping groove 341 or the second clamping groove 351, and the adjustment bolt 37 passes through the fixed clamp 35 or the adjustment clamp 34 and is connected to the adjustment member 36. Specifically, the first clamping groove 341 and the second clamping groove 351 are arc grooves, and a plurality of the first clamping grooves 341 and the second clamping grooves 351 are vertically spaced apart. In a specific implementation, the first clamping groove 341 and the second clamping groove 351 have the same size, which is convenient for fixing the culture dish 2. The adjustment member 36 is an arc member, and the size of the inner arc surface thereof matches the outer diameter of the culture dish 2, and the size of the outer arc surface thereof matches the first clamping groove 341 and the second clamping groove 351.

[0035] During use, place the culture dish 2 between the symmetrically arranged first clamping groove 341 and the second clamping groove 351, and then rotate the adjustment bolt 37 to finely adjust the adjustment member 36 so that the adjustment member 36 clamps the culture dish 2, thereby clamping culture dishes 2 with different outer diameters in the same column.

[0036] See Figure 1 and Figure 2 As shown in, in a specific embodiment, it further includes a transmission assembly and a second rotating shaft 38. The transmission assembly is a belt transmission member, including a first belt pulley and a second belt pulley. The first belt pulley is connected to the first rotating shaft 33, the second belt pulley is connected to the second rotating shaft 38, and both ends of the second rotating shaft 38 are rotatably connected to the incubator 1 and are arranged parallel and spaced apart from the first rotating shaft 33 up and down. Through the arrangement of the transmission assembly and the second rotating shaft 38, the stability of the adjustment clamp 34 and the smoothness of movement are increased. In a specific implementation, both ends of the second rotating shaft 38 are round shafts and are connected to the left and right side walls of the incubator 1 through bearings. The middle part is processed with an external thread. The lower end of the adjustment clamp 34 is provided with a threaded hole 342 that cooperates with it. The lower end of the fixed clamp 35 is provided with a through hole 352 with a diameter larger than the outer diameter of the second rotating shaft 38.

Moreover, the adjusting clamp 34 is movably matched with the first rotating shaft 33 through a screw pair. The first rotating shaft 33 is controlled by a motor 31. By controlling the motor 31 to drive the first rotating shaft 33 to rotate, multiple adjusting clamps 34 which are in screw fit with the first rotating shaft 33 can move axially along the first rotating shaft 33, approaching or departing from the fixedly clamp 35. When approaching the fixedly clamp 35, the culture dish 2 is clamped and fixed. When departing from the fixedly clamp 35, the culture dish 2 is released. Meanwhile, the clamping force is adjusted through the adjusting assembly arranged on the fixedly clamp 35 and the adjusting clamp 34, so that the fixedly clamp 35 and the adjusting clamp 34 can simultaneously fix culture dishes 2 with different outer diameter sizes, thereby increasing the number of culture dishes 2 placed by the Bacillus screening device and improving the experimental efficiency.
