Description

Technical Field

[0001] This utility model relates to the field of microbial experimental technology, specifically to a device for preparing slant culture medium. Background Technology

[0002] Currently, when preparing slant culture medium, the laminar flow hood is first disinfected and sterilized. A rubber or plastic tube with a height of about 1.5 cm is placed on the surface of the laminar flow hood. While still hot, the unsolidified culture medium is dispensed quantitatively into the test tube, the tube opening is sterilized, and the tube is stoppered. Then, the upper end of the test tube opening is placed on the rubber tube, allowing the culture medium in the test tube to tilt naturally. The tilt is adjusted to increase the surface area of ​​the culture in the test tube, and the culture is solidified into a slant.

[0003] In practice, the test tubes are easy to roll due to their smooth surface, which leads to unevenness on the slant surface and thus failure. At the same time, since the outer diameter of the rubber tube is fixed, different outer diameter rubber tubes are required when preparing culture media with different slant surfaces, which takes up a lot of space. Therefore, we propose a slant culture medium preparation device to solve the above problems. Utility Model Content

[0018] 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. Example

[0019] Reference Figure 1 , 2 This is the first embodiment of the present invention. This embodiment provides a slant culture medium preparation device, including a base plate 1. A support frame 2 is fixedly connected to one side of the top of the base plate 1. The support frame 2 has several movable openings 3. A fixed seat 4 is hinged in each movable opening 3. One side of a test tube 5 is sleeved in the fixed seat 4. The bottom of the other side of the test tube 5 abuts against an adjustment seat 7. An adjustment component 8 is fixedly connected to the bottom of the adjustment seat 7. The adjustment component 8 is fixedly connected to the other side of the top of the base plate 1. A sealing plug 6 is provided at the opening of the test tube 5.

[0020] The culture medium is quantitatively injected into test tube 5, and then a sealing plug 6 is inserted into the opening of test tube 5 to seal the test tube 5. Then, the tail end of test tube 5 is inserted into the mounting hole 41 of the fixing seat 4. The rubber ring 42 clamps and fixes test tube 5 by friction. Then, the open end of test tube 5 is placed on the adjusting seat 7. According to the required tilt angle, the adjusting component 8 is operated to drive the fixed adjusting seat 7 to rise and fall. The adjusting seat 7 drives test tube 5 to change the tilt angle with the hinge position of the fixing seat 4 as the center, which facilitates the preparation of culture media with different slant surfaces. Example

[0021] Reference Figure 1-4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, the fixing base 4 is provided with a through mounting hole 41. A rubber ring 42 is fixedly sleeved in the mounting hole 41. The tail end of the test tube 5 is inserted into the mounting hole 41 of the fixing base 4. The rubber ring 42 clamps and fixes the test tube 5 by friction.

[0022] Specifically, the top of the adjusting seat 7 is provided with a U-shaped groove, which facilitates the adjusting seat 7 to support and limit the test tube 5.

[0023] Specifically, a rotating shaft 62 is coaxially mounted inside the sealing plug 6. One end of the rotating shaft 62 is fixedly connected to an adjusting knob 66, which is rotatably mounted outside the sealing plug 6. A cavity 67 is hollow on one side inside the sealing plug 6. A vertical baffle 65 is slidably provided inside the cavity 67. One end of the vertical baffle 65 is fixedly connected to the outer wall of the rotating shaft 62, and the other end of the vertical baffle 65 is fixedly connected to a fan-shaped sealing plate 64. The fan-shaped sealing plate 64 is slidably disposed inside the cavity 67. A receiving groove 61 is opened on the inner wall of one end of the cavity 67. A liquid inlet hole 63 is opened on one side of the cavity 67, which is correspondingly arranged with the fan-shaped sealing plate 64. A drain pipe 68 is opened on the other side of the cavity 67, which is located away from the fan-shaped sealing plate 64.

[0024] Furthermore, the cavity 67 has a semi-cylindrical structure, with the receiving groove 61 corresponding to the fan-shaped sealing plate 64. The culture medium is quantitatively injected into the test tube 5, and then a sealing plug 6 is inserted into the opening of the test tube 5. The fan-shaped sealing plate 64 of the sealing plug 6 seals the inlet hole 63. The fan-shaped sealing plate 64 is held in place by friction. When a small amount of culture medium needs to be poured out before it solidifies, the adjusting knob 66 ​​is turned, causing the fixed rotating shaft 62 to rotate. The rotating shaft 62 causes the fixed vertical baffle 65 to rotate circumferentially, and the vertical baffle 65 causes the fixed fan-shaped sealing plate 64 to move synchronously. 64 releases the seal on the inlet hole 63, and at the same time, the fan-shaped sealing plate 64 is embedded into the receiving tank 61. At this time, the test tube 5 is inverted, and the culture medium inside the test tube 5 flows into the cavity 67 through the inlet hole 63. After reaching the required amount, the adjustment knob 66 ​​is rotated in the opposite direction, which drives the rotating shaft 62 to rotate in the opposite direction. The rotating shaft 62 drives the fan-shaped sealing plate 64 and the vertical baffle 65 to move. The fan-shaped sealing plate 64 is moved out of the receiving tank 61 and seals the inlet hole 63. The vertical baffle 65 pushes and squeezes the culture medium in the cavity 67, so that the culture medium is finally discharged quantitatively from the drain pipe 68.

[0025] Specifically, the adjustment assembly 8 includes a base 81, an internally threaded cylinder 82, an externally threaded rod 83, a handwheel 84, a worm gear 85, and a worm 86. The bottom end of the base 81 is fixedly connected to the base plate 1. Several internally threaded cylinders 82 are rotatably installed inside the base 81. Each internally threaded cylinder 82 is fitted with an externally threaded rod 83 through a threaded structure. One end of each externally threaded rod 83 is fixedly connected to an adjustment seat 7. Each internally threaded cylinder 82 is fixedly fitted with a worm gear 85. One side of each worm gear 85 is meshed with a worm 86. The worm 86 is rotatably installed inside the base 81, and one end of the worm 86 is fixedly connected to the handwheel 84. The handwheel 84 is rotatably located outside the base 81.

[0026] Furthermore, vertical grooves 831 are recessed on both sides of the external threaded rod 83, and a limiting slider 821 is slidably engaged in the vertical grooves 831. The limiting slider 821 is fixedly connected to the base 81.

[0027] According to the required tilt angle, operate the adjustment component 8 and turn the handwheel 84. The handwheel 84 drives the worm gear mechanism to work, which in turn drives the internal threaded cylinder 82 to rotate. The internal threaded cylinder 82 drives the external threaded rod 83 to lift and lower through the threaded structure. The external threaded rod 83 drives the fixed adjustment seat 7 to lift and lower. The adjustment seat 7 drives the test tube 5 to change the tilt angle with the hinge position of the fixed seat 4 as the center, which is convenient for preparing culture media with different slopes. Example

[0028] Reference Figure 1-4 This is the third embodiment of the present invention. Based on the previous two embodiments, in use, the culture medium is quantitatively injected into the test tube 5. Then, a sealing plug 6 is placed at the opening of the test tube 5. The fan-shaped sealing plate 64 of the sealing plug 6 blocks the inlet hole 63. The fan-shaped sealing plate 64 is held in place by friction. When a small amount of culture medium needs to be poured out before it solidifies, the adjusting knob 66 ​​is turned, causing the fixed rotating shaft 62 to rotate. The rotating shaft 62 causes the fixed vertical baffle 65 to rotate circumferentially. The vertical baffle 65 causes the fixed fan-shaped sealing plate 64 to move synchronously, disengaging the fan-shaped sealing plate 64 from the inlet hole 63. Simultaneously, the fan-shaped sealing plate 64 is embedded into the receiving groove 61. At this time, the test tube 5 is inverted, and the culture medium inside the test tube 5 flows into the cavity 67 through the inlet hole 63. After reaching the required amount, the adjusting knob 66 ​​is turned in the opposite direction, causing the rotating shaft 62 to rotate in the opposite direction. The rotating shaft 62 then drives the fan-shaped sealing plate 64 and the vertical baffle 65... The fan-shaped sealing plate 64 is moved out of the receiving groove 61 and blocks the liquid inlet 63. The vertical baffle 65 pushes and squeezes the culture medium in the cavity 67, so that the culture medium is finally discharged quantitatively from the drain tube 68. The drain tube 68 is a sterile tube. The discharged solution is finally collected through an external container. Then, the tail end of the test tube 5 is inserted into the mounting hole 41 of the fixing seat 4. The rubber ring 42 clamps and fixes the test tube 5 by friction. Then, the open end of the test tube 5 is placed on the adjusting seat 7. According to the required tilt angle, the adjusting component 8 is operated and the handwheel 84 is turned. The handwheel 84 drives the worm gear mechanism to work, which in turn drives the internal threaded cylinder 82 to rotate. The internal threaded cylinder 82 drives the external threaded rod 83 to rise and fall through the thread structure. The external threaded rod 83 drives the fixed adjusting seat 7 to rise and fall. The adjusting seat 7 drives the test tube 5 to change the tilt angle with the hinge position of the fixing seat 4 as the center, which facilitates the preparation of culture media with different slopes.
