Description

Technical Field

[0001] The invention relates to the technical field of microorganism homogenization, in particular to a homogenization device for microorganism testing. Background Art

[0002] Microbial homogenization is a laboratory technique used to break up microbial cells in order to extract intracellular substances such as DNA, RNA, protein, etc. A microbial homogenizer is a device specifically used for microbial sample processing. It can evenly disperse microbial cells in the experimental medium to ensure the accuracy and reliability of the experimental results. Microbial homogenizers usually use high-speed vibration and stirring. Through the combined action of the vibrator and the stirrer, the experimental sample and the medium are fully mixed to achieve the purpose of homogenization.

[0003] The existing homogenizer has a fixed internal blade position during use. When there are many raw materials to be homogenized, all the raw materials cannot be fully stirred, which will result in the inability to homogenize the microorganisms. In addition, the existing homogenizer uses a raw material bottle with a blade to hold the raw materials, and then reversely clamps it on the upper end of the motor for homogenization. If the blade is loose, it is easy to cause the raw materials to leak. Summary of the invention

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0018] like Figure 1-Figure 7 As shown, a homogenizing device for microbial testing of the present invention comprises a U-shaped frame 1, an adjusting component 2 is arranged on the side wall of the U-shaped frame 1, a supporting component 3 is arranged at the other end of the U-shaped frame 1, and a stirring component 4 is arranged at the upper end of the U-shaped frame 1; The adjustment component 2 includes a moving bar 21, a rubber pad 25 and a slide groove 26. Two fixing holes 22 are arranged on the surface of the moving bar 21. A U-shaped rod 23 is fixedly inserted inside the fixing hole 22. A rubber sheet 24 is embedded on the side wall of the moving bar 21. The rubber pad 25 is embedded on the inner wall of the U-shaped frame 1. Two slide grooves 26 are symmetrically arranged on the inner wall of the U-shaped frame 1. The two ends of the U-shaped rod 23 are slidably connected in the two slide grooves 26. Both ends of the U-shaped rod 23 are arranged with a rotating hole 27. The rotating hole 27 is rotatably connected with a rotating shaft 28 inside. The surface of the rotating shaft 28 is fixedly sleeved with an extrusion plate 2 9. A push rod 210 is fixedly connected to a side wall of the extrusion plate 29. The push rod 210 is pushed to drive the extrusion plate 29 to rotate, so that one end of the extrusion plate 29 is squeezed on the outer wall of the U-shaped frame 1. The pulling force generated by the extrusion pulls the two ends of the U-shaped rod 23 to move, so that the U-shaped rod 23 pulls the moving bar 21, and the rubber sheet 24 is squeezed on the rubber pad 25 through the moving bar 21. The position of the moving bar 21 is fixed by the friction between the rubber sheet 24 and the rubber pad 25, and then the position of the rubber cover 31 on the U-shaped rod 23 is fixed, and the rubber cover 31 is sealed to prevent the leakage of the raw material.

[0019] Specifically, the supporting assembly 3 includes a rubber cover 31 and a circular hole 34. The rubber cover 31 is sleeved on the surface of the U-shaped rod 23. A conical clamping ring 32 is fixedly connected to the lower surface of the rubber cover 31. A sleeve 33 is fixedly sleeved at the center of the rubber cover 31. The circular hole 34 is opened on the upper surface of the U-shaped frame 1. The upper end of the sleeve 33 is inserted into the circular hole 34. A clamping ring 35 is fixedly sleeved on the outer wall of the upper end of the sleeve 33. The lower end of the conical clamping ring 32 is clamped on the bottle 36. The drive shaft 44 is supported by the sleeve 33 to keep the drive shaft 44 rotating stably. At the same time, the sleeve 33 is limited by the clamping ring 35 to prevent the sleeve from being separated from the circular hole 34. The sleeve 33 can slide in the circular hole 34 to facilitate the adjustment of the height of the rubber cover 31.

[0020] Specifically, the stirring assembly 4 includes a top plate 41 and two through holes 48. The upper surface of the top plate 41 is fixedly connected to a motor 42. The output end of the motor 42 is fixedly connected to a drive shaft 44. A plug hole 43 is provided on the surface of the top plate 41. The drive shaft 44 is inserted into the plug hole 43. The lower end of the drive shaft 44 is inserted into the sleeve 33. The lower end of the drive shaft 44 is fixedly connected to a stirring blade 45. Two fixed rods 46 are fixedly connected to the lower surface of the top plate 41. The surface of the fixed rod 46 is slidably sleeved. A spring 47 and a through hole 48 are provided on the upper surface of the U-shaped frame 1, a fixing rod 46 is inserted into the through hole 48, and the lower end of the fixing rod 46 is fixedly connected to the same connecting strip 49. The starting motor 42 drives the driving shaft 44 to rotate, and the driving shaft 44 drives the stirring blade 45 to rotate when rotating, and at the same time presses the top plate 41 to move downward, and then pushes the top plate 41 upward through the spring 47, and repeatedly presses the top plate 41 to drive the driving shaft 44 to move up and down, thereby driving the stirring blade 45 to move up and down to evenly stir the raw materials.

[0021] Specifically, the rubber sheet 24 corresponds to the rubber pad 25 , and the rubber sheet 24 protrudes from the moving bar 21 , and the position of the moving bar 21 is fixed by the friction between the rubber sheet 24 and the rubber pad 25 .

[0022] Specifically, a curved surface is formed at one end of the lower surface of the extrusion plate 29 , and the curved surface is arranged at one end of the extrusion plate 29 close to the U-shaped frame 1 . The curved surface facilitates the extrusion plate 29 to rotate and clamp on the outer wall of the U-shaped frame 1 .

[0023] Specifically, the connecting bar 49 is disposed at the lower end of the moving bar 21 , and the length of the connecting bar 49 is longer than the length of the moving bar 21 , so that the connecting bar 49 and the fixing rod 46 surround the moving bar 21 to prevent the connecting bar 49 and the moving bar 21 from colliding.

[0024] Specifically, the spring 47 is located between the top plate 41 and the U-shaped frame 1, and the spring 47 is in a normal pressure state. The top plate 41 is pushed upward by the spring 47, so that the top plate 41 is pressed to move up and down continuously.

[0025] When in use, first put the raw material into the material bottle 36, then put the material bottle 36 on the bottom inner wall of the U-shaped frame 1, and then push the rubber cover 31 downward, so that the rubber cover 31 drives the cone clamping ring 32 to clamp at the opening of the material bottle 36. When the cone clamping ring 32 is stably clamped with the material bottle 36, push the push rod 210 to drive the extrusion plate 29 to rotate, so that one end of the extrusion plate 29 is squeezed on the outer wall of the U-shaped frame 1, and the tension generated by the extrusion pulls the two ends of the U-shaped rod 23 to move, so that the U-shaped rod 23 pulls the moving bar 21, and the moving bar 21 drives the rubber sheet 24 to be squeezed on On the rubber pad 25, the position of the movable bar 21 is fixed by the friction force between the rubber sheet 24 and the rubber pad 25, and then the position of the rubber cover 31 on the U-shaped rod 23 is fixed, and the material bottle 36 is sealed by the rubber cover 31 to prevent leakage of raw materials, and then the motor 42 is started to drive the drive shaft 44 to rotate. When the drive shaft 44 rotates, it drives the stirring knife 45 to rotate, and at the same time presses the top plate 41 to move down, and then pushes the top plate 41 up through the spring 47, and repeatedly presses to make the top plate 41 drive the drive shaft 44 to move up and down, and then drives the stirring knife 45 to move up and down to evenly stir the raw materials.
