[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0026] Example 1
[0027] like Figure 1-5 As shown, this embodiment provides a laboratory bacterial extraction device, including a grip rod 1, a fixing rod 11 is fixedly connected to the bottom of the grip rod 1, a sleeve 2 is inserted into the bottom of the fixing rod 11, a storage component 3 is provided inside the grip rod 1, and a disassembly component 4 is provided inside the sleeve 2.
[0028] like Figure 2 and Figure 3 As shown, in this embodiment, the storage assembly 3 includes a rotating block 31, the outer surface of the handle 1 is provided with a thread, the inner wall of the rotating block 31 is threadedly connected to the outer surface of the handle 1, and the inner wall of the handle 1 is provided with two square grooves 2;
[0029] Furthermore, the inner walls of the two square grooves are fixedly connected to round rods 32, and the outer surfaces of the two round rods 32 are slidably connected to a moving block 33, and the top of the moving block 33 is in contact with the bottom of the rotating block 31, and the bottom of the moving block 33 is fixedly connected to a fixed rod 2 34, and the outer surface of the fixed rod 2 34 is provided with a spring 1 35.
[0030] The top of the spring 1 35 is fixedly connected to the bottom of the moving block 33 , the bottom of the spring 1 35 is fixedly connected to the bottom of the inner wall of the handle 1 , and the bottom of the fixed rod 2 34 is fixedly connected to a scraper 36 .
[0031] During implementation, since the outer surface of the handle 1 is provided with a thread, when the rotating block 31 rotates clockwise, it will move downward. The downward movement of the rotating block 31 will push the moving block 33 to move downward, and rotating the rotating block 31 counterclockwise will move the rotating block 31 upward. During the upward movement of the rotating block 31, the deformed spring 35 will push the moving block 33 to move upward and return to its original position through the elastic force generated, so that the scraper 36 can be moved to the inside of the fixed rod 11, so that the scraper 36 can be accommodated inside the fixed rod 11 when the device is not in use, which can avoid damage to the scraper 36 caused by accidental collision, falling, etc., which helps to extend the service life of the scraper and reduce equipment maintenance costs.
[0032] Furthermore, in order to achieve the purpose that the staff does not need to replace the new curette every time the bacteria are extracted, refer to Figure 4 In this embodiment, the disassembly component 4 includes two hollow frames 41, and two square grooves are provided on the inner wall of the fixing rod 11. The inner walls of the two square grooves are fixedly connected to the outer surface of the hollow frame 41 on the same side. The two hollow frames 41 are symmetrically arranged with the center of the fixing rod 11. A scraper block 42 is provided inside the sleeve 2, and the scraper block 42 is located below the two hollow frames 41.
[0033] During the implementation process, the limit block 411 inside the hollow frame 41 enables the staff to quickly and conveniently disassemble and install the sleeve 2 and clean the scraper block 42 inside the sleeve 2, ensuring that the scraper can always maintain a sterile state and ensure that it is clean every time it is used.
[0034] Example 2
[0035] The only difference between this embodiment and the first embodiment is that Figure 4 The inner wall of the hollow frame 41 is rotatably connected to a limit block 411, and one end of the limit block 411 close to the center of the fixed rod 11 is fixedly connected to a spring 2 412, and one end of the spring 2 412 away from the limit block 411 is fixedly connected to the inner wall of the hollow frame 41.
[0036] The inner wall of the sleeve 2 is provided with two slots, and the ends of the bottoms of the two limit blocks 411 away from the center of the fixing rod 11 are both convex, and the surfaces of the convex parts of the bottom of the spring 2 412 are in contact with the inner wall of the slot on the same side.
[0037] During use, by pressing the two limit blocks 411 toward the inside of the fixed rod 11, the two limit blocks 411 rotate and can be moved out of the slots provided inside the sleeve 2, thereby releasing the restriction on the sleeve 2 and allowing the sleeve 2 to be removed, so that the staff can clean the sleeve 2 conveniently. It is not necessary to replace a new scraper every time bacteria are extracted, thereby reducing the cost of consumables and the complexity of the operation.
[0038] Example 3
[0039] The only difference between this embodiment and the first or second embodiment is that, see Figure 5 The scraper block 42 is fixedly connected to two spring threes 421 on the left side, and the left sides of the two spring threes 421 are fixedly connected to the inner wall of the sleeve 2. The front and back sides of the scraper block 42 are fixedly connected to the limiting rods 423. The inner wall of the sleeve 2 is fixedly connected to two fixed blocks 422. The two fixed blocks 422 are provided with a sliding groove on the side close to each other, and the two limiting rods 423 are slidably connected to the inner wall of the sliding groove on the same side away from the scraper block 42.
[0040] When the scraper 36 moves upward, since the right side of the scraper block 42 is in close contact with the surface of the scraper 36, the bacterial liquid remaining on the surface of the scraper 36 will be scraped off by the scraper block 42, so that the staff does not need to use other tools to scrape off the residual bacterial liquid, reducing the workload of the staff and improving the practicality of the device.
[0041] To sum up, the utility model can release the restriction on the sleeve by pressing the two limit blocks toward the inside of the fixed rod, and the sleeve can be removed, so that the staff can clean the sleeve conveniently. There is no need to replace a new scraper every time bacteria are extracted, thereby reducing the cost of consumables, reducing the complexity of operation, and improving the efficiency of the experimental process.
[0042] At the same time, when the bacteria are extracted, the deformed spring pushes the moving block upward to return to its original position, so that the scraper can be moved into the inside of the fixed rod, which can avoid damage to the scraper caused by accidental collision or falling, help to extend the service life of the scraper and reduce equipment maintenance costs.
[0043] The working principle of the utility model is as follows: when the staff needs to extract bacteria from the culture dish or reagent bottle, first rotate the rotating block 31 clockwise. Since the outer surface of the grip rod 1 is provided with a thread, when the rotating block 31 rotates clockwise, it moves downward, and the downward movement of the rotating block 31 pushes the moving block 33 to move downward. The downward movement of the moving block 33 drives the fixed rod 2 34 to move downward, so that the scraper 36 at the bottom of the fixed rod 2 34 can be moved out of the fixed rod 1 1. When the moving block 33 moves downward, it presses the spring 1 35 to deform it. When the scraper As the spoon 36 moves downward, it contacts the top of the scraper 42. Since the top of the scraper 42 is a curved surface, the scraper 42 is pushed to the left as the spoon 36 moves downward. As the scraper 42 moves to the left, it squeezes the spring 3 421, causing the spring 3 421 to deform. The deformed spring 3 421 generates an elastic force to the right, so that the right side of the scraper 42 can be tightly attached to the surface of the spoon 36. When the staff completes the extraction of bacteria, they rotate the rotating block 31 counterclockwise to move the rotating block 31 upward. As the rotating block 31 moves upward, The deformed spring 35 will push the moving block 33 upward to return to its original position through the elastic force generated, so that the scraper 36 can be moved to the inside of the fixed rod 11, so that the scraper 36 can be stored inside the fixed rod 11 when the device is not in use, which can avoid damage to the scraper 36 caused by accidental collision or falling, thereby helping to extend the service life of the scraper and reduce equipment maintenance costs. When the scraper 36 moves upward, the right side of the scraper block 42 is in close contact with the surface of the scraper 36, and the bacterial liquid remaining on the surface of the scraper 36 will be scraped off by the scraper block 42, so that the staff does not have to use other tools to remove the bacteria. The residual bacterial liquid is scraped off, which reduces the workload of the staff and improves the practicality of the device. When the device is used, by pressing the two limit blocks 411 into the fixed rod 11, the two limit blocks 411 are rotated to move out of the slots opened inside the sleeve 2, thereby releasing the restriction on the sleeve 2 and removing the sleeve 2, so that the staff can clean the sleeve 2 conveniently. It is no longer necessary to replace a new scraper every time bacteria are extracted, which reduces the cost of consumables, reduces the complexity of operation, and improves the efficiency of the experimental process.
