Description

Technical Field

[0001] The present invention relates to the field of culture dish coating, and more specifically, to a microorganism detection culture dish coating device. Background Art

[0002] Spreading is an important microbial inoculation and culture technology. It evenly distributes microbial samples on solid culture medium. Its main purpose is to count colonies, separate and culture or detect the sensitivity of culture medium, etc. The coating quality is one of the key factors affecting the accuracy and reliability of experimental results.

[0003] In the prior art, an operator usually holds a cotton swab or other coating tool to coat the microbial sample inside the culture dish. For example, a Chinese patent with a publication number of CN212610618U discloses a novel rapid manual microbial coating device, which is provided with a fan-shaped coating sheet on the coating head, and can be rotated to coat the surface of the culture medium in all directions, thereby simplifying the coating operation and making the coating more uniform, which helps to improve the coating quality.

[0042] like Figures 1 to 10 As shown, an embodiment of the present invention provides a microorganism detection culture dish coating device, including an operating table 11, wherein the upper outer surface of the operating table 11 is rotatably connected to a support plate 17, and the upper outer surface of the support plate 17 is movably connected to a movable seat 35, the upper end of the movable seat 35 is open, and the inner side of the movable seat 35 is provided with a clamping component for clamping and fixing the culture dish 20.

[0043] The clamping assembly includes an ear seat 37 fixedly connected to the lower side of the inner surface of the movable seat 35, the ear seats 37 are in several groups and are distributed in a ring array, the outer surface of the ear seat 37 is fixedly connected to a support rod 38, the support rod 38 is in a circular ring shape, the outer surface of the support rod 38 is rotatably connected to a bracket 36, the bracket 36 is in an L-shaped structure, the upper side of the outer surface of the bracket 36 is fixedly connected to a contact plate 39, the outer surface of the contact plate 39 is in contact with the culture dish 20, the bracket 36 is in several groups and is distributed in a ring array.

[0044] By adopting the above technical solution, when performing the coating operation, the support plate 17 is rotatably supported by the operating table 11 so that the support plate 17 can rotate at the upper end of the operating table 11, and the support plate 17 supports the movable seat 35 for placing the culture dish 20. During the coating process, in order to keep the culture dish 20 stable and improve the coating quality, a clamping component is set. Before working, the culture dish 20 is placed on the upper side of the L-shaped bracket 36, and the culture dish 20 is supported by the bracket 36. At the same time, the bracket 36 will be supported by the support rod 38 under the gravity of the culture dish 20. The fulcrum rotates, and the movable seat 35 fixes and supports the support rod 38 through the ear seat 37. As the bracket 36 gradually flips over, the contact plate 39 on its upper side will be driven to fit into contact with the culture dish 20. The culture dish 20 is clamped and fixed by the contact plates 39 distributed in a ring array, which can effectively improve the stability of the culture dish 20 during the coating process and help reduce the risk of accidental overturning of the culture dish 20. By setting up a clamping component, a good clamping effect can be achieved for culture dishes 20 of different diameters, thereby ensuring the coating accuracy of the microbial samples.

[0045] like Figure 1 , Figure 4 and Figure 6 As shown, a support assembly is provided on the upper side of the operating table 11, and the support assembly includes a fixed shaft 13 fixedly connected to the outer surface of the upper end of the operating table 11, a notch 14 is provided on the outer surface of the fixed shaft 13, a spiral groove is provided on the inner side of the notch 14, the fixed shaft 13 is connected to a spiral sleeve 15 through a spiral groove spiral transmission, the outer surface of the spiral sleeve 15 is connected to a support plate 16 for damping rotation, and a surrounding plate 12 is fixedly connected to the outer surface of the upper end of the operating table 11.

[0046] The outer surface of the lower end of the support plate 16 is fixedly connected with a mounting sleeve 21, the inner surface of the mounting sleeve 21 is fixedly connected with a clamping block 22, the inner side of the mounting sleeve 21 is slidably connected with a feed pipe 24, the outer surface of the feed pipe 24 is provided with a clamping groove 23, the feed pipe 24 is clamped and connected with the mounting sleeve 21 through the clamping groove 23, and a coating pipe 32 is arranged at the lower side of the feed pipe 24.

[0047] By adopting the above technical solution, the operating table 11 supports the fixed shaft 13, and the notch 14 on the surface of the fixed shaft 13 is connected with the spiral sleeve 15 in a spiral transmission. The operator can rotate the spiral sleeve 15 to make it move up and down along the inner wall of the notch 14, so that the height of the spiral sleeve 15 can be flexibly adjusted. The notch 14 can block and limit the spiral sleeve 15. The support rod 38 is connected with the spiral sleeve 15 through damping rotation. In the absence of external force, the support plate 16 will remain stationary, and in the presence of external force, the support plate 16 can be spirally moved. The sleeve 15 is rotated at the fulcrum, so that the position of the support plate 16 can be adjusted, so as to further improve the operating convenience of the coating equipment. The support plate 16 fixes and supports the mounting sleeve 21. When installing the material taking tube 24, the slot 23 on the upper side of the material taking tube 24 is engaged with the block 22 inside the mounting sleeve 21 to limit the position, so that the material taking tube 24 can be quickly installed on the lower side of the mounting sleeve 21. When working, the coating equipment can be quickly installed and positioned by setting the support assembly, thereby effectively improving the operating convenience and flexibility of the coating equipment.

[0048] like Figure 4 , Figure 6 and Figure 7 As shown, a coating assembly is provided on the inner side of the feeding tube 24, and the coating assembly includes a cavity 25 embedded in the feeding tube 24, and a ventilation groove 27 is provided on the outer surface of the feeding tube 24. The number of the ventilation grooves 27 is several groups and distributed in a ring array, and the outer surface of the feeding tube 24 is fixedly connected to a capsule 26, and the inner surface of the capsule 26 is fixedly connected to an elastic plate 28, and the elastic plate 28 is fixedly connected to the outer surface of the feeding tube 24 at one end away from the capsule 26.

[0049] A guide groove 29 is embedded on the inner side of the material taking tube 24, and a feed pipe 30 is embedded and fixedly connected to the inner side of the material taking tube 24. The feed pipe 30 is communicated with the inside of the guide groove 29. A retaining ring 31 is fixedly connected to the outer surface of the lower end of the material taking tube 24. A rotating sleeve 33 is spirally connected to the inner surface of the retaining ring 31. The inner surface of the rotating sleeve 33 is inclined. The inner surface of the rotating sleeve 33 is in rotational contact with an extrusion sleeve 34. The extrusion sleeve 34 is located on the outer side of the coating tube 32. The lower end of the coating tube 32 is rotatably connected to a rotating cylinder 44. Through holes 47 are evenly opened on the outer surface of the rotating cylinder 44. The lower side of the outer surface of the rotating cylinder 44 is in rotational contact with the inner surface of the culture dish 20.

[0050] By adopting the above technical solution, during the microbial coating operation, an appropriate amount of microbial material is injected into the feed pipe 30, and then the microbial material enters the guide groove through the feed pipe 30 and is guided to the coating pipe 32 through the guide groove 29 under the action of gravity, and then the operator squeezes the capsule 26. As the volume of the capsule 26 decreases, the gas inside the capsule 26 enters the cavity 25 inside the feed pipe 24 through the ventilation groove 27, and then the gas enters the coating pipe 32 through the guide groove 29, thereby pushing the microbial material inside the coating pipe 32 and accelerating the injection of the microbial material into the rotating cylinder 44. When the capsule 26 is compressed, the elastic plate 28 inside it is squeezed. When the operator releases the capsule 26, the capsule 26 is elastically The plate 28 will continue to expand outward under the elastic force, and at this time, the external gas will enter the capsule 26 through the feed pipe 30. After the microbial material enters the rotating cylinder 44, it will be discharged to the outside from the through hole 47 on the surface of the rotating cylinder 44, and the microbial material will be evenly coated on the surface of the culture dish 20 through the rotating contact between the rotating cylinder 44 and the culture dish 20, thereby completing the rapid coating operation. By setting up a coating component, the microbial material can be evenly coated on the surface of the culture dish 20, while ensuring the operating accuracy, the difficulty of the coating operation can also be reduced, and the probability of the operator's hand directly contacting the culture dish 20 can also be reduced, thereby reducing the risk of the operator being infected by microorganisms, thereby improving the safety of the microbial coating process.

[0051] like Figure 5 and Figure 7 As shown, a rotating assembly is arranged between the coating tube 32 and the rotating cylinder 44, and the rotating assembly includes a connecting seat 41 fixedly connected to the outer surface of the coating tube 32, the connecting seat 41 is in a circular ring shape, and a guide seat 42 is fixedly connected to the outer surface of the connecting seat 41, and a guide groove 43 is provided on the outer surface of the right end of the rotating cylinder 44, and the guide seat 42 is located inside the guide groove 43 and is in rotational contact with the guide groove 43, and a movable groove 50 is embedded on the inner side of the connecting seat 41, and two groups of partitions 59 are fixedly connected inside the movable groove 50.

[0052] The movable groove 50 is in an arc shape, and a piston plate 51 is slidably connected to the inner surface of the movable groove 50, and a piston rod 52 is fixedly connected to the outer surface of the movable plate. The piston rod 52 is in an arc shape, and one end of the piston rod 52 away from the piston plate 51 is fixedly connected to a connecting block 53, and the connecting block 53 is fixedly connected to the outer surface of the right end of the rotating cylinder 44. A branch pipe 60 is embedded and fixedly connected to the front side of the connecting seat 41, and the branch pipe 60 is respectively connected to the movable groove 50 and the inside of the coating tube 32.

[0053] By adopting the above technical solution, during the coating operation, the coating tube 32 fixedly supports the connecting seat 41, and the connecting seat 41 can rotatably support the rotating cylinder 44 through the cooperation of the guide seat 42 and the guide groove 43. In order to make the rotating cylinder 44 fully contact with the culture dish 20, a rotating component is provided. When working, during the extrusion process of the capsule 26, part of the gas inside the coating tube 32 will enter the movable groove 50 through the branch pipe 60, and the two groups of partitions 59 are respectively located at both ends of the movable groove 50 to separate and seal the movable groove 50. At this time, the piston plate 51 will move along the inside of the movable groove 50 under the push of the gas. The piston plate 51 will drive the piston rod 52 to move synchronously during the movement, and the piston rod 52 will drive the connecting block 53 to move in an arc shape during the movement. The connecting block 53 will drive the rotating cylinder 44 to rotate synchronously during the movement. During the rotation of the rotating cylinder 44, the guide seat 42 will slide synchronously inside the guide groove 43. The guide groove 43 can make the rotating cylinder 44 rotate more smoothly. The rotation of the rotating cylinder 44 can make the rotating cylinder 44 fully contact with the surface of the culture dish 20 during the coating process, thereby further improving the coating uniformity and further improving the accuracy of microbial coating detection.

[0054] like Figure 4 and Figure 7 As shown, a stirring assembly is provided on the inner side of the rotating cylinder 44, and the stirring assembly includes a rotating sleeve 45 fixedly connected to the left end of the inner surface of the rotating cylinder 44, a mounting plate 49 is fixedly connected to the inner surface of the rotating cylinder 44, a movable rod 46 is rotatably connected between the mounting plate 49 and the rotating sleeve 45, and stirring rods 48 are fixedly connected to the outer surface of the movable rod 46, and the number of the stirring rods 48 is several groups and is symmetrically distributed.

[0055] By adopting the above technical solution, the rotating cylinder 44 fixedly supports the mounting plate 49 and the rotating sleeve 45, thereby rotatably supporting the movable rod 46 through the rotating sleeve 45 and the mounting plate 49. During the rotation of the rotating cylinder 44, the movable rod 46 cooperates with the stirring rod 48 to fully stir the microbial material inside the rotating cylinder 44, which not only helps to improve the uniformity of the microbial coating, but also, under the stirring action of the stirring rod 48, can accelerate the microbial material inside the rotating cylinder 44 to be discharged into the culture dish 20 through the through hole 47, thereby significantly improving the operating stability of the coating equipment.

[0056] like Figure 4 , Fig. 9 and Fig.10As shown, a shaking assembly is arranged on the outer side of the movable seat 35, and the shaking assembly includes a motor 18 fixedly connected to the inner side of the operating table 11, a driving rod 19 is fixedly connected to the upper end of the output shaft of the motor 18, a pull rod 54 is fixedly connected to the upper end of the driving rod 19, and the pull rod 54 is fixedly connected to the support plate 17. A ball 40 is embedded and rotatably connected on the inner side of the movable seat 35, and the lower side of the outer surface of the ball 40 is in rolling contact with the outer surface of the support plate 17.

[0058] By adopting the above technical solution, in order to further improve the contact effect between the rotating cylinder 44 and the culture dish 20, a shaking component is set. During the coating operation, the motor 18 is started and the drive rod 19 is driven to rotate synchronously through the output shaft of the motor 18. The pull rod 54 is fixedly connected with the drive rod 19 to drive the support plate 17 to rotate along the upper surface of the operating table 11. During the rotation of the support plate 17, the movable seat 35 will rotate synchronously under the action of friction, thereby driving the culture dish 20 to rotate through the movable seat 35, so that the culture dish 20 can fully contact the rotating cylinder 44, and the microbial material is evenly coated on the surface of the culture dish 20. The pull rod 54 fixedly supports the sliding rod 57 and drives the sliding rod 57 to move in a circle. The slide groove is distributed in a straight line, and the pull rod 54 will drive the slide rod 57 to move synchronously during the rotation. The slide rod 57 is supported by the sliding sleeve 58 and the slide groove 55. The slide rod 57 will drive the sliding sleeve 58 to slide linearly inside the slide groove 55 during the rotation, so that the movable seat 35 can be driven to move in the horizontal direction through the slide groove 55, so that the movable seat 35 can slide in different directions during the rotation, thereby further improving the coating quality of the microbial material. The ball 40 on the lower side of the movable seat 35 and the rolling support on the upper surface of the support plate 17 can further improve the stability of the movable seat 35 during the translation process, thereby further improving the operating reliability of the shaking assembly.

[0059] The workflow of the technical solution provided by the present invention is as follows:
