Abstract
Description
Technical Field
[0001] This utility model relates to the field of separation equipment technology, and in particular to a microbial strain separation device. Background Technology
[0002] A microbial strain refers to a pure culture of any microorganism isolated from nature. It is a pure population and its offspring propagated from an independently isolated single cell (or a single virus particle), possessing unique genetic and phenotypic characteristics. Currently, most microbial strains require the use of test tubes during the isolation process.
[0003] In existing technologies, such as the "Microbial Strain Isolation Device" with Chinese Patent No. CN221918069U, a tube body and a storage device are included. A rubber stopper is provided on the lower surface of the tube body. The storage device is located on one side of the tube body and includes an elastic rope fixedly connected to the tube body. The side of the elastic rope away from the tube body is fixedly connected to the rubber stopper. A fixing rod is fixedly connected to the lower surface of the tube body. A groove is formed on the surface of the rubber stopper, and the fixing rod is inserted into the groove. A rope is fixedly connected to one side of the rubber stopper, and a magnet is fixedly connected to the side of the rope away from the rubber stopper. This invention, by providing a storage device, facilitates the storage and stacking of the rubber stopper, and also allows the tube body to stand upright, reducing the possibility of rubber stopper loss and simplifying use. However, this separation device lacks a protective structure for the tube body, making it susceptible to breakage from impacts during storage, thus reducing its lifespan. Therefore, improvements are needed. Utility Model Content
[0004] The purpose of this invention is to solve the problem that the tube body is easily broken by impact from external objects during storage in the existing technology, and to propose a microbial strain separation device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a microbial strain isolation device, comprising a protective shell, a test tube body, and a rubber stopper. The inner surface of the protective shell is provided with a slot. An insert plate is fixedly installed at the bottom of the test tube body. A limiting hole is provided on one side of the insert plate and the protective shell. A fixing ring is fixedly installed on the inner wall of the limiting hole. A limiting block is slidably connected inside the limiting hole. A connecting column is fixedly installed at the end of the limiting block near the fixing ring. A pull rod is fixedly installed on the outer wall of the end of the connecting column away from the limiting block. A return spring is sleeved on the outer wall of the connecting column.
[0006] Preferably, the insert plate and the slot are slidably connected, and the connecting post and the fixing ring are slidably connected.
[0007] Preferably, one end of the reset spring is fixedly connected to the limiting block, and the other end of the reset spring is fixedly connected to the fixing ring.
[0008] Preferably, the test tube body and the protective shell are slidably connected, and the rubber stopper is slidably connected to the test tube body.
[0009] Preferably, a fixing sleeve is fixedly installed on one side of the protective shell, a magnetic block is fixedly installed on the top of the fixing sleeve, a cleaning brush is slidably connected inside the fixing sleeve, a fixing post is fixedly installed on the top of the cleaning brush, a connecting block is fixedly installed on the top of the fixing post, and a metal connecting rod is fixedly installed on the outer wall of the connecting block.
[0010] Preferably, the metal connecting rod is adsorbed to the magnetic block, and the connecting block is slidably connected to the fixing sleeve.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0012] 1. In this utility model, by pulling the lever, the connecting column slides inside the fixed ring. During the sliding process, the connecting column drives the limiting block to slide inside the limiting hole. During the sliding process, the limiting block compresses the return spring towards the fixed ring. After a certain degree of compression, the limiting block releases the restriction on the insert plate. After release, the test tube body is inserted into the protective shell. After the insertion reaches the limit distance, the insert plate at the bottom of the test tube body will be inserted into the slot inside the protective shell. After insertion, the lever is released. After release, the rebound force of the return spring will push the limiting block into the limiting hole, thereby limiting the test tube body inside the protective shell. This design improves the storage safety of the test tube body by limiting it inside the protective shell, effectively preventing the test tube body from being easily broken by external impacts during storage.
[0013] 2. In this utility model, by pulling the metal connecting rod upward, the connecting block slides upward inside the fixed sleeve. During the upward sliding process, the connecting block will drive the fixed column and the cleaning brush to move upward together. After moving a certain distance, the cleaning brush can be taken out. After taking it out, the cleaning brush can be used to clean the inside of the test tube body. After cleaning, the cleaning brush, fixed column, connecting block and metal connecting rod are returned to their original positions. After returning to their original positions, the magnetic block will attract the metal connecting rod. This design realizes the function of rapid cleaning of the test tube body, eliminating the need to search for special test tube brushes and other cleaning tools among many tools, thus improving efficiency.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0021] Example 1: As Figures 1-3 As shown, this utility model provides a technical solution: a microbial strain isolation device, including a protective shell 1, a test tube body 2, and a rubber stopper 3. A slot 4 is provided on the inner surface of the protective shell 1. An insert plate 5 is fixedly installed at the bottom of the test tube body 2. A limiting hole 6 is provided on one side of the insert plate 5 and the protective shell 1. A fixing ring 7 is fixedly installed on the inner wall of the limiting hole 6. A limiting block 8 is slidably connected inside the limiting hole 6. A connecting post 9 is fixedly installed at one end of the limiting block 8 near the fixing ring 7. A pull rod 10 is fixedly installed on the outer wall of the connecting post 9 away from the limiting block 8. A return spring 11 is sleeved on the outer wall of the connecting post 9. The insert plate 5 is slidably connected to the slot 4. The connecting post 9 is slidably connected to the fixing ring 7. One end of the return spring 11 is fixedly connected to the limiting block 8. The other end of the return spring 11 is fixedly connected to the fixing ring 7. The test tube body 2 is slidably connected to the protective shell 1. The rubber stopper 3 is slidably connected to the test tube body 2.
[0022] In this embodiment, by pulling the lever 10, the connecting post 9 is moved to slide inside the fixed ring 7. During the sliding process, the connecting post 9 will cause the limiting block 8 to slide inside the limiting hole 6. During the sliding process, the limiting block 8 will compress the return spring 11 towards the fixed ring 7. After a certain degree of compression, the limiting block 8 will release the restriction on the insert plate 5. After the restriction is released, the test tube body 2 is inserted into the protective shell 1. After the insertion reaches the limit distance, the insert plate 5 at the bottom of the test tube body 2 will be inserted into the slot 4 inside the protective shell 1. After insertion, the lever 10 is released. After the release, the rebound force of the return spring 11 will push the limiting block 8 into the limiting hole 6, thereby limiting the test tube body 2 inside the protective shell 1. This design improves the storage safety of the test tube body 2 by limiting the test tube body 2 inside the protective shell 1, and effectively prevents the test tube body 2 from being easily broken by external impacts during storage.
[0023] Example 2: Figure 4 As shown, a fixing sleeve 12 is fixedly installed on one side of the protective shell 1. A magnetic block 13 is fixedly installed on the top of the fixing sleeve 12. A cleaning brush 14 is slidably connected inside the fixing sleeve 12. A fixing post 15 is fixedly installed on the top of the cleaning brush 14. A connecting block 16 is fixedly installed on the top of the fixing post 15. A metal connecting rod 17 is fixedly installed on the outer wall of the connecting block 16. The metal connecting rod 17 is attracted to the magnetic block 13. The connecting block 16 is slidably connected to the fixing sleeve 12.
[0024] In this embodiment, by pulling the metal connecting rod 17 upward, the connecting block 16 slides upward inside the fixed sleeve 12. During the upward sliding process, the connecting block 16 will drive the fixed post 15 and the cleaning brush 14 to move upward together. After moving a certain distance, the cleaning brush 14 can be taken out. After taking it out, the cleaning brush 14 can be used to clean the inside of the test tube body 2. After cleaning, the cleaning brush 14, fixed post 15, connecting block 16 and metal connecting rod 17 are returned to their original positions. After returning to their original positions, the magnetic block 13 will attract the metal connecting rod 17. This design realizes the rapid cleaning function of the test tube body 2, so that it does not need to search for special test tube brushes and other cleaning tools among many tools, thus improving efficiency.
[0025] The working principle of this embodiment is as follows: In use, first pull the lever 10, which drives the connecting column 9 to slide inside the fixed ring 7. During the sliding process, the connecting column 9 will drive the limiting block 8 to slide inside the limiting hole 6. During the sliding process, the limiting block 8 will compress the return spring 11 towards the fixed ring 7. After a certain degree of compression, the limiting block 8 will release the restriction on the insert plate 5. After the restriction is released, the test tube body 2 is inserted into the protective shell 1. After the insertion reaches the limit distance, the insert plate 5 at the bottom of the test tube body 2 will be inserted into the slot 4 inside the protective shell 1. After insertion, the lever 10 is released. After the release, the rebound force of the return spring 11 will push the limiting block 8 into the limiting hole 6, thereby limiting the test tube body 2 inside the protective shell 1. This design improves the storage safety of the test tube body 2 by limiting the test tube body 2 inside the protective shell 1, and effectively prevents the test tube body 2 from being easily broken by external impacts during storage. When it is necessary to clean the inside of the test tube body 2, first pull the metal connecting rod 17 upward. The metal connecting rod 17 drives the connecting block 16 to slide upward inside the fixed sleeve 12. During the upward sliding process, the connecting block 16 will drive the fixed post 15 and the cleaning brush 14 to move upward together. After moving a certain distance, the cleaning brush 14 can be taken out. After taking it out, the cleaning brush 14 can be used to clean the inside of the test tube body 2. After cleaning, the cleaning brush 14, fixed post 15, connecting block 16 and metal connecting rod 17 are returned to their original positions. After returning to their original positions, the magnetic block 13 will attract the metal connecting rod 17. This design realizes the rapid cleaning function of the test tube body 2, so that it does not need to search for special test tube brushes and other cleaning tools among many tools, thus improving efficiency.
