[0015] The utility model technical solution has the following advantages:

[0016] 1. The utility model completes the installation of the support plate by inserting the slide groove into the slide groove surface. This structure can install the chemical reagent on the surface of the installation plate and then install the support plate into the working box. This can effectively avoid the situation where the reagents collide with the inner wall of the working box due to the obstruction of the field of vision when the reagents are placed one by one close to the inside of the working box. After the support plate is installed, the combination of the damper and the spring can provide a certain shock absorption for the installation plate to avoid the reagents from being violently shaken and causing the chemical substances in the reagents to react, thereby improving the reliability of the equipment.

DETAILED DESCRIPTION

[0025] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figures 1 to 5 As shown, a Class 100 chemical safety cabinet for preventing chemicals from shaking comprises: a working box 1, a slide rail 2 is fixedly connected to the inner bottom wall of the working box 1, a slide groove 3 is slidably connected to the surface of the slide rail 2, a support plate 4 is fixedly connected to the surface of the slide groove 3, a damper 5 is fixedly connected to the four sides of the top of the support plate 4, a spring 6 is overlapped on the surface of the damper 5, and a mounting plate 7 is fixedly connected to the top of the damper 5;

[0027] After installing the reagent tubes, align the slide groove 3 at the bottom of the support plate 4 with the slide rail 2 in the working box 1, and slide it into the surface of the slide rail 2 to fix the support plate 4. When the equipment stores the reagent tubes and the working box 1 is vibrated, the damper 5 and the spring 6 can be used together to reduce the shock of the mounting plate 7 to prevent the mounting plate 7 from being affected by the vibration and causing the chemical reagents to be affected.

[0028] Reference Figure 4 and Figure 6 As shown, a first fixed block 8 is fixedly connected to the top of the mounting plate 7, a hand wheel 9 is rotatably connected to one side of the first fixed block 8, a threaded rod 10 is fixedly connected to one side of the hand wheel 9, and the surface of the threaded rod 10 is rotatably connected to the inner wall of the first fixed block 8, a second fixed block 11 is threadedly connected to the surface of the threaded rod 10, and the bottom of the second fixed block 11 overlaps the top of the mounting plate 7, a sliding rod 12 is fixedly connected to one side of the inner wall of the first fixed block 8, and the surface of the sliding rod 12 is slidably connected to the inner wall of the second fixed block 11;

[0029] First, place the reagent tube between the first fixed block 8 and the second fixed block 11, and then turn the handwheel 9. The rotation of the handwheel 9 drives the threaded rod 10 on one side to rotate, and the rotation of the threaded rod 10 drives the second fixed block 11 on the surface to move. The sliding rod 12 can limit the moving trajectory of the second fixed block 11. The second fixed block 11 moves closer to the first fixed block 8, thereby fixing the reagent tube between the two groups of fixed blocks.

[0030] Reference Figures 1 to 3 As shown, a first collecting groove 13 is provided on the surface of the mounting plate 7, a second collecting groove 14 is provided on the surface of the supporting plate 4, a box door 15 is rotatably connected to the front of the working box 1, a handle 16 is fixedly connected to the surface of the box door 15, a connecting pipe 17 is fixedly connected to the middle of the inner wall of the working box 1, a mounting box 18 is fixedly connected to one end of the connecting pipe 17, a collecting box 19 is slidably connected to the inner wall of the mounting box 18, a pull handle 20 is fixedly connected to one side of the collecting box 19, and an electric valve 21 is provided on the inner wall of the connecting pipe 17;

[0031] When the chemicals in the reagent tube are spilled, the chemical liquid flows into the second collecting groove 14 on the surface of the support plate 4 through the first collecting groove 13 on the surface of the mounting plate 7, and then enters the connecting pipe 17 through the second collecting groove 14. The electric valve 21 is then opened to allow the overflowing chemical liquid to flow into the collecting box 19 through the connecting pipe 17. The electric valve 21 is then closed to prevent the chemical liquid in the collecting box 19 from evaporating and flowing back into the working box 1 through the connecting pipe 17. When it is necessary to deal with the overflowing chemical liquid, first hold the pull handle 20 to pull the collecting box 19 out of the mounting box 18, and then deal with the liquid in the collecting box 19. The staff can hold the handle 16 to rotate the box door 15 to open it.

[0032] Working principle: first place the reagent tube between the first fixed block 8 and the second fixed block 11, then turn the hand wheel 9, so that the rotation of the threaded rod 10 drives the second fixed block 11 on the surface to move, and the second fixed block 11 moves closer to the first fixed block 8, thereby fixing the reagent tube between the two groups of fixed blocks, and then align the slide groove 3 at the bottom of the support plate 4 with the slide rail 2 in the working box 1, and slide it into the surface of the slide rail 2, thereby completing the fixation of the support plate 4. When the chemicals in the reagent tube are spilled, the chemical liquid enters the connecting pipe 17 through the first collecting tank 13 and the second collecting tank 14, and finally flows into the collection box 19 through the connecting pipe 17.

[0033] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the utility model creation.
