Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a stirrer shielding and splash-proof device. Background Art

[0002] During the experiment, a stirrer is often used to prepare sample slurry for the next experimental treatment. However, during the stirring process, small sample droplets will inevitably splash out, causing adverse effects on the experimenters and the experimental environment. Therefore, the opening of the container needs to be covered.

[0003] Currently, during the test process, paper with holes in it is usually used to cover the opening at the top of the container. However, when making a hole in the paper, it is not convenient to accurately control the size of the hole. Once the hole is too large, some droplets will still splash out. At the same time, the splashing droplets will also wet the covering paper, resulting in sample waste and pollution of the working environment.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a stirrer shielding and anti-splashing device is provided. Utility Model Content

[0005] The purpose of the utility model is to provide a stirrer shielding and anti-splashing device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an agitator shielding and anti-splashing device, comprising a cover plate and an adjusting component, a through hole is opened in the middle of the cover plate, the adjusting component is arranged on the top of the cover plate, the adjusting component comprises a slide groove, a slider, a baffle, a slide column, a driving ring and a guide groove, a slide groove is opened on the top of the cover plate, and the inside of the slide groove is slidably connected with the slider, a baffle is fixed on the top of the slider, and a slide column is connected to one end of the top of the baffle, the top of the baffle is slidably connected with the driving ring, and a guide groove is opened inside the driving ring.

[0007] Furthermore, the slide grooves are inclined, and are distributed equidistantly around the top of the cover plate.

[0008] Furthermore, the diameter of the sliding column is equal to the width of the guide groove, and the sliding column is slidably connected to the driving ring through the guide groove.

[0009] Furthermore, a rubber pad is fixed to the bottom of the cover plate, and a scraper ring is arranged in the middle of the cover plate.

[0010] Furthermore, the baffle is triangular in shape, and is slidably connected to the scraper ring.

[0011] Furthermore, a limiting groove is provided on the outer side of the cover plate, and the outer side of the cover plate is slidably connected to a limiting block.

[0012] Furthermore, the limit block is in a right-angle shape, and the limit block is fixedly connected to the drive ring.

[0013] Furthermore, the width of the limiting block is substantially consistent with the width of the limiting groove, and the limiting block fits the rubber pad.

[0014] The utility model provides a stirrer shielding and anti-splashing device, which has the following beneficial effects:

[0015] 1. The utility model adjusts the components so that when the stirring rod of the stirrer passes through the through hole of the cover plate, the driving ring can be rotated to make the slide column slide inside the guide groove. At the same time, the slide groove and the slider guide the moving direction of the baffle, so that all the baffles can be controlled to move at the same time to form central holes of different sizes, so that they can fit stirring rods of different diameters, thereby avoiding the splashing of droplets inside the container during stirring, which is conducive to improving the adaptability range of the device;

[0016] 2. The utility model can improve the fit between the cover plate and the top of the test container and avoid splashing of the solution by setting the rubber pad. At the same time, the rubber pad can also provide friction to the limit block, so as to avoid the drive ring from accidentally rotating after adjustment and changing the size of the center hole. In the process of the center hole becoming larger, the scraper ring can also scrape and clean the bottom of the baffle, which is beneficial to improving the convenience of subsequent maintenance. When the drive ring is rotated to move the limit block to the limit groove, the restriction between the drive ring and the cover plate can be released, making it very convenient to disassemble and clean the whole, which is beneficial to improving the convenience of maintenance.

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figures 1 to 3 As shown, a stirrer shielding and anti-splashing device comprises a cover plate 1 and an adjusting component 3. A through hole 2 is provided in the middle of the cover plate 1. The adjusting component 3 is arranged on the top of the cover plate 1. The adjusting component 3 comprises a slide groove 301, a slider 302, a baffle 303, a slide column 304, a driving ring 305 and a guide groove 306. A slide groove 301 is provided on the top of the cover plate 1, and the slider 302 is slidably connected inside the slide groove 301. The slide groove 301 is inclined, and the slide grooves 301 are equidistantly distributed around the top of the cover plate 1. A baffle 303 is fixed on the top of the slider 302, and a slide column 304 is connected to one end of the top of the baffle 303. The slider 302 It will slide in the slide groove 301, thereby guiding the moving direction of the baffle 303. The top of the baffle 303 is slidably connected to the drive ring 305, and a guide groove 306 is opened inside the drive ring 305. The diameter of the slide column 304 is equal to the width of the guide groove 306, and the slide column 304 is slidably connected to the drive ring 305 through the guide groove 306. The drive ring 305 can be rotated to make the slide column 304 slide inside the guide groove 306, which can simultaneously control the movement of all the baffles 303 to form central holes of different sizes, so that it can fit the stirring rods of different diameters, thereby avoiding the splashing of droplets inside the container during stirring.

[0023] like Figure 1 and Figure 2 As shown, a rubber pad 4 is fixed to the bottom of the cover plate 1, and a scraper ring 5 is arranged in the middle of the cover plate 1. The rubber pad 4 will improve the fit between the cover plate 1 and the top of the test container to prevent the solution from leaking out. The baffle 303 is triangular in shape, and the baffle 303 is slidably connected to the scraper ring 5. In the process of the central hole becoming larger, the scraper ring 5 can scrape and clean the bottom of the baffle 303, which is conducive to improving the convenience of subsequent maintenance. A limiting groove 6 is provided on the outer side of the cover plate 1, and the outer side of the cover plate 1 is slidably connected to a limiting block 7. The limiting block 7 is in a right angle shape, and the limit block 7 is fixedly connected to the drive ring 305. When the drive ring 305 is rotated to move the limit block 7 to the limit groove 6, the restriction between the drive ring 305 and the cover plate 1 can be released, making it very convenient to disassemble and clean the entirety. The width of the limit block 7 is substantially consistent with the width of the limit groove 6, and the limit block 7 fits with the rubber pad 4, which can also provide a certain friction resistance to the limit block 7, thereby preventing the drive ring 305 from accidentally rotating after adjustment and changing the size of the center hole.

[0024] In summary, the stirrer shielding anti-splashing device, when used, first according to Figure 1 , Figure 2 and Figure 3The structure shown in the figure, first, place the container under the stirrer, and then cover the top of the container with the cover 1. At this time, use the rubber pad 4 to improve the fit between the cover 1 and the top of the test container. Secondly, rotate the drive ring 305 clockwise to make the slide column 304 slide inside the guide groove 306, and the slider 302 will slide in the slide groove 301, thereby guiding the moving direction of the baffle 303, so that all the baffles 303 can be controlled to move at the same time to form a larger central hole, so that the stirring blade of the stirrer passes through the through hole 2 of the cover 1. Then, after the stirring rod of the stirrer passes through the through hole 2 of the cover 1, it can be rotated counterclockwise. The needle rotates the drive ring 305, and similarly it can make it fit the stirring rods of different diameters. Then, after adjustment, the rubber pad 4 can also provide a certain friction resistance to the limit block 7, so as to prevent the drive ring 305 from accidentally rotating after adjustment and changing the size of the center hole. Later, when taking out the stirring shaft of the stirrer, when the drive ring 305 is rotated to make the center hole larger, the scraper ring 5 can also scrape and clean the bottom of the baffle 303. Finally, during cleaning and maintenance, it is only necessary to rotate the drive ring 305 to move the limit block 7 to the limit groove 6 to release the restriction between the drive ring 305 and the cover plate 1, so that the overall disassembly and cleaning is also very convenient.
