When the circular groove plate 11 of the bottom cover 1 and the circular ring 21 of the top cover 2 are in a fit, the circular ring 21 will bring the rotating plate 41 and the rotating column 42 closer to the inside of the fixed shell 12. Due to the shape of the extrusion block 45, the extrusion block 45 gradually pushes the rotating plate 41 to both sides and moves the rotating plate 41 to the slotted position of the limit block 43. Under the pushing action of the compression spring 47, the extrusion block 45 and the limit block 43 limit the movement of the rotating plate 41.

[0018] The bottom cover 1 includes a circular groove plate 11, the outer wall of the circular groove plate 11 is fixedly connected with a fixed shell 12, the inner wall of the fixed shell 12 is slidably connected with the outer wall of the pressing block 44 through a sliding groove 13, and the sliding groove 13 is opened in the wall of the fixed shell 12, the inner wall of the fixed shell 12 is fixedly connected with the outer wall of the limit block 43, the inner wall of the fixed shell 12 is fixedly connected with the end of the damping rod 46 away from the extrusion block 45, and the inner wall of the fixed shell 12 is fixedly connected with the end of the compression spring 47 away from the extrusion block 45. When the culture dish needs to be opened, a force is applied to the pressing block 44, so that the pressing block 44 moves along the sliding groove 13 in the direction away from the top cover 2. At this time, the compression spring 47 and the damping rod 46 are squeezed, and the extrusion block 45 no longer supports the rotating plate 41, so that the rotating plate 41 leaves the position of the limit block 43 under the action of its own gravity, so that the top cover 2 can leave the outer wall of the bottom cover 1.

[0019] The top cover 2 includes a circular ring 21, the inner wall of the circular ring 21 is fixedly connected with an observation piece 22, the outer wall of the circular ring 21 is fixedly connected with a positioning box 23, the inner wall of the positioning box 23 is rotatably connected to the outer wall of the rotating column 42, the end of the positioning box 23 close to the sleeve ring 3 is fixedly connected with a fixed magnetic block 5, the inner wall of the circular ring 21 is slidably connected to the outer wall of the circular groove plate 11, the sleeve ring 3 includes a rotating ring 31, a groove 32 is opened in the wall of the rotating ring 31, the end of the rotating ring 31 close to the top cover 2 is fixedly connected with a magnetic strip 33, the inner wall of the rotating ring 31 is slidably connected to the outer wall of the circular ring 21 Then, the outer wall of the magnetic strip 33 is slidably connected with the outer wall of the circular ring 21, and the rotating ring 31 on the circular ring 21 is rotated, so that the magnetic strip 33 on the rotating ring 31 is close to the fixed magnetic block 5 on the positioning box 23, until the fixed magnetic block 5 reaches the raised position on the positioning box 23 and attracts each other with the magnetic strip 33. Due to the magnetic effect of the magnetic strip 33 and the fixed magnetic block 5, the ring 3 is fixed on the circular ring 21, so that the culture dish has a label that is easy to disassemble, avoiding damage to the observation sheet 22 on the culture dish caused by removing the sticker attached to the top cover 2.

[0020] Working principle:

[0021] When in use, after culturing Phellinus igniarius, the bottom cover 1 and the top cover 2 are closed to provide a sterile environment for Phellinus igniarius. When the circular groove plate 11 of the bottom cover 1 and the circular ring 21 of the top cover 2 are fitted together, the circular ring 21 will bring the rotating plate 41 and the rotating column 42 close to the interior of the fixed shell 12. Due to the shape of the extrusion block 45, the extrusion block 45 gradually pushes the rotating plate 41 to both sides and moves the rotating plate 41 to the slotted position of the limit block 43. Under the pushing action of the compression spring 47, the extrusion block 45 and the limit block 43 limit the movement of the rotating plate 41. At this time, the bottom cover 1 and the top cover 2 are fitted together, so that the bottom cover 1 and the top cover 2 is fixed by the locking device 4, so as to achieve the purpose of quickly locking the culture dish. When the culture dish needs to be opened, force is applied to the pressing block 44, so that the pressing block 44 moves along the sliding groove 13 in the direction away from the top cover 2. At this time, the compression spring 47 and the damping rod 46 are squeezed, so that the squeezing block 45 is retracted into the interior of the fixed shell 12. When the culture dish is in use, the side of the bottom cover 1 away from the top cover 2 is placed on the desktop. At this time, the squeezing block 45 no longer supports the rotating plate 41, so that the rotating plate 41 leaves the position of the limit block 43 under the action of its own gravity, so that the top cover 2 can leave the outer wall of the bottom cover 1.

[0022] The sleeve ring 3 can be installed on the circular ring 21 of the top cover 2. When the culture dish needs to be marked, a label can be attached to the groove 32 of the rotating ring 31 before installing the sleeve ring 3, and then the rotating ring 31 of the sleeve ring 3 is put on the side of the circular ring 21 away from the bottom cover 1. At this time, the rotating ring 31 is rotated to make the magnetic strip 33 on the rotating ring 31 close to the fixed magnetic block 5 on the positioning box 23 until the fixed magnetic block 5 reaches the raised position on the positioning box 23 and attracts the magnetic strip 33. Due to the magnetic effect of the magnetic strip 33 and the fixed magnetic block 5, the sleeve ring 3 is fixed on the circular ring 21, so that the culture dish obtains a label that is easy to remove, avoiding damage to the observation sheet 22 on the culture dish caused by removing the sticker attached to the top cover 2.

[0023] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
