Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 This utility model provides a technical solution: a chemical reagent test petri dish, including a box body 1, a fixing frame 12 connected to the inner wall of the box body 1, a plurality of damping rods 11 slidably connected to the inner wall of the fixing frame 12, a buffer spring 9 sleeved on the outer surface of the plurality of damping rods 11, a clamping block 10 connected to the end of each damping rod 11 away from the fixing frame 12, the outer surface of the plurality of clamping blocks 10 being made of sponge material, a sealing cover 5 hinged to the top of the fixing frame 12, and a locking block 4 connected to the right side of the sealing cover 5.
[0021] The box 1 contains a culture dish body 8. The outer surface of the culture dish body 8 is in contact with the inner wall of multiple clamping blocks 10. The contact between the clamping blocks 10 and the culture dish body 8 ensures the stability of the culture dish body 8 during transportation.
[0022] The petri dish body 8 is provided with a bottom layer 19, and a culture layer 18 is connected to the upper surface of the bottom layer 19. The culture layer 18 is located above the bottom layer 19 and provides appropriate support for culture medium and other experimental materials, which is conducive to the growth of microorganisms, cells or other biological materials. A label layer 17 is connected to the upper surface of the culture layer 18.
[0023] The bottom surface of the box 1 is connected to multiple support rods 7, and the bottom surface of each support rod 7 is connected to an adsorption plate 6. The use of the adsorption plate 6 ensures stability during transportation.
[0024] The bottom surface of the box 1 is connected to a negative pressure pump 16, the front surface of the negative pressure pump 16 is connected to a vent pipe 13, the outer surface of the vent pipe 13 is fitted with a fixing plate 14, and the upper surface of the fixing plate 14 is connected to the upper surface of the box 1. The use of the negative pressure pump 16 ensures that the air inside the adsorption plate 6 can be extracted.
[0025] The outer surface of the negative pressure pump 16 is connected to multiple connecting pipes 15. The end of each connecting pipe 15 away from the negative pressure pump 16 penetrates the outer wall of the adsorption disk 6 and communicates with the inside, thereby enabling the adsorption disk 6 to be extracted to achieve the stability of the box 1.
[0026] The upper surface of the box body 1 is hinged with a cover plate 2, and the upper surface of the cover plate 2 is connected with a locking plate 3. The cooperation between the cover plate 2 and the locking plate 3 seals the petri dish body 8 inside the box body 1, further ensuring the safety of the petri dish body 8.
[0027] Working principle: When the culture dish body 8 needs to be transferred or transported, the culture dish body 8 is placed on the inner wall of the clamping block 10 inside the box 1. Due to the cooperation of the fixing frame 12 with the buffer spring 9 and the damping rod 11, it can adapt to culture dishes of various sizes. Then, the cooperation of the sealing cover 5 and the locking block 4 tightly seals the culture dish body 8 inside, preventing the reagents inside the culture dish from escaping due to bumps. Subsequently, the cooperation of the negative pressure pump 16 and the connecting pipe 15 extracts the air inside the adsorption plate 6, so that the box 1 can be stably adsorbed on the placement plate, avoiding displacement and collision of the box 1 during transportation, which would damage or leak the culture dish body 8 inside. Of course, the cooperation of the clamping block 10 with the buffer spring 9 and the damping rod 11 will absorb the shaking of the culture dish body 8 even during bumps. Finally, the cooperation of the cover plate 2 and the locking plate 3 seals the box 1.
