[0002] A petri dish is a laboratory vessel used for microbial or cell culture. It consists of a flat disc-shaped bottom and a lid, and is generally made of glass or plastic. There are basically two types of petri dish materials, mainly plastic and glass. Glass can be used for plant materials, microbial culture, and adherent culture of animal cells. Plastic may be made of polyethylene, and there are disposable and reusable ones. They are suitable for laboratory inoculation, streaking, and bacterial isolation operations. They can be used for the cultivation of plant materials. After placing liquids or objects in the petri dish, it is sealed to cultivate microorganisms and begin to multiply.
[0003] However, there are some problems with the prior art: the existing culture dish generally has an upper dish cover directly covering the lower dish cover, which is tightly clamped by fitting the edges. Since the staff usually wear gloves and the culture dish is often made of glass, when opening the lid, the gloves may fall off the staff's hands and fall to the ground because they have no friction, causing damage to the culture dish and loss of materials. Therefore, we propose a culture dish that is easy to open and close. Utility Model Content

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.
[0022] like Figure 1-5 A culture dish that is easy to open and close is shown, comprising:
[0023] A lower dish cover 1 is provided with a ring 3 on its surface, the ring 3 is sleeved on the lower dish cover 1 and fixedly connected to the lower dish cover 1, a rotating component 4 is provided on one end of the surface of the ring 3, and an upper dish cover 2 is fixedly connected to one end of the rotating component 4. The upper dish cover 2 is driven by the rotating component 4 to rotate downward, and then closed with the lower dish cover 1 to form a closed state.
[0024] The upper dish cover 2 is rotated by the rotating assembly 4 to fit tightly with the lower dish cover 1, so that the upper dish cover 2 and the inner cavity of the lower dish cover 1 form a closed state, and a fixing assembly 7 is fixedly installed on one side of the surface of the lower dish cover 1. The lower dish cover 1 and the upper dish cover 2 are closed by the fixing assembly 7. After the upper dish cover 2 covers the lower dish cover 1, the lower dish cover 1 and the upper dish cover 2 are fixedly connected by the fixing assembly 7.
[0025] The upper dish cover 2 is rotatably connected to a handle 5. When the culture dish needs to be opened, the fixing assembly 7 is first opened so that the upper dish cover 1 and the lower dish cover 2 are no longer fixedly connected. Then the handle 5 is rotated and pulled upward, and then the upper dish cover 2 can be opened, and the staff can test the sample on the lower dish cover 1.
[0026] The rotating assembly 4 includes a fixed block 401 which is arranged in a U shape and is fixedly mounted on one end of the upper surface of the collar 3 . The fixed block 401 is arranged to facilitate the rotating block 403 to rotate thereon.
[0027] A first rotating shaft 402 is rotatably connected to the fixed block 401, and a rotating block 403 is fixedly installed on the surface of the first rotating shaft 402. One end of the rotating block 403 is fixedly connected to the surface of the upper dish cover 2. The upper dish cover 2 is tightly fitted with the lower dish cover 1 through the rotating block 403 and the first rotating shaft 402. When it is necessary to open or close the culture dish, it is only necessary to pull or put down the upper dish cover 2, and the rotating block 403 on the fixed block 401 will be driven to rotate.
[0028] Positioning blocks 8 are fixedly installed at both ends of the surface of the upper dish cover 2. The positioning blocks 8 are U-shaped, and one side of the positioning blocks 8 is arc-shaped to facilitate connection with the surface of the upper dish cover 2. A buckle 6 is formed on one side of the surface of the upper dish cover 2. The buckle 6 is engaged with the fixing component 7. The upper dish cover 2 and the lower dish cover 1 can be fixedly connected through the engagement of the fixing component 7 with the buckle 6.
[0029] A handle 5 is rotatably connected between the two groups of positioning blocks 8. The handle 5 is arranged in a semicircular shape. A second rotating shaft 9 is arranged between the positioning block 8 and the handle 5. The handle 5 is rotatably connected to the positioning block 8 through the second rotating shaft 9. When it is necessary to open the culture dish, the handle 5 needs to be rotated ninety degrees to make the handle 5 vertical. Then, the handle 5 is pulled upward, and the upper dish cover 2 can be dragged upward, so that the culture dish can be opened.
[0030] The fixing assembly 7 includes a fixing plate 701, one side of which is arranged in an arc shape to facilitate connection with the surface of the lower dish cover 1. A circular hole is opened on the surface of the fixing plate 701, and a tension spring 702 is arranged in the circular hole. A sleeve 703 is fixedly connected to the surface of the fixing plate 701. The circular hole is located in the sleeve 703, and the tension spring 702 is responsible for pulling the rotating column 704 to slide toward the fixing plate 701.
[0031] A U-shaped notch is provided on the surface of the sleeve 703, and a rotating column 704 is rotatably connected inside the sleeve 703. One end of the rotating column 704 is fixedly connected to the tension spring 702, and a knob 706 is fixedly installed on the other end of the rotating column 704. A hook 705 is formed on the surface of the rotating column 704, and the hook 705 is located in the U-shaped notch. The hook 705 is engaged with the buckle 6. When it is necessary to fix the upper dish cover 2 and the lower dish cover 1, it is necessary to pull the rotating column 704, and then after pulling it to a suitable position, rotate the knob 706, and then the knob 706 drives the rotating column 704 to rotate together. When the hook 705 on the rotating column 704 is fully inserted into the hole of the buckle 6, the rotating column 704 is released. Under the pull of the tension spring 702, the rotating column 704 slides toward the fixed plate 701, thereby fixing the upper dish cover 2 and the lower dish cover 1.
[0032] The above embodiments are only used to help understand the method and core idea of the utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made to the utility model without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
