Abstract
Description
Technical Field
[0001] The utility model relates to a bidirectionally locked culture dish, belonging to the technical field of culture dishes. Background Art
[0002] A culture dish is a laboratory vessel used for microbial culture. It consists of a flat disc-shaped dish body and a flat disc-shaped dish cover. The material is generally polystyrene plastic and is suitable for disposable use. Conventional culture dishes often have a threaded connection between the dish body and the dish cover. This method often requires the operator to rotate the dish cover multiple times to achieve locking with the dish body; therefore, a culture dish with a lock or locking feature has appeared in the prior art (CN 102575213 A, CN 216142015 U), but the above-mentioned culture dish can only achieve one-way locking, which easily leads to the inability to lock the dish body and the dish cover after reverse rotation. Therefore, the operator needs to rotate the dish cover again to achieve locking; and if locking is not achieved after reverse rotation, if the operator misjudges the locking state, it will cause the dish cover and the dish body to be easily disengaged, which will seriously affect the cultivation of microorganisms. Utility Model Content
[0003] The utility model aims to provide a bidirectionally lockable culture dish, wherein the cover and the body of the culture dish can be bidirectionally locked, which is convenient for personnel to operate and provides a guarantee for the cultivation of microorganisms.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A bidirectionally lockable culture dish comprises a dish cover and a dish body; a plurality of stoppers are formed on the outer circumference of the opening of the dish body, and a plurality of protrusions are formed on the dish body at both sides of each stopper;
[0006] The inner circumference of the dish cover is provided with a plurality of anti-slipping parts corresponding to the stopper part, each anti-slipping part forms a gap with the top of the dish cover for the stopper part and the protrusion to be screwed in, and a locking part is formed on the inner side of the dish cover in each gap, and the locking part is located at the non-edge of the anti-slipping part;
[0007] The dish cover and the dish body can be bidirectionally locked, and when locked, the locking portion is inserted between two adjacent protrusions on one side of the corresponding stop portion or between the protrusion and the stop portion.
[0008] Preferably, the dish cover and the dish body are both made of polystyrene.
[0009] Preferably, the distance between the protrusion and the vertical center line of the dish body is greater than the distance between the stopper and the vertical center line of the dish body.
[0010] Preferably, the outer edges of the protrusion and the locking portion are arc-shaped, and the outer edge of the stopping portion is square.
[0011] Preferably, the locking portion is located in a gap on the upper side of the middle portion of the anti-slip portion.
[0012] The beneficial effects of the utility model are:
[0013] A gap is formed between the anti-slip portion and the dish cover, and a locking portion is arranged in the gap. The locking portion cooperates with the anti-slip portions and the dish cover on both sides to form an area for the stop portion and the protrusion to be embedded in regardless of whether the dish cover is rotated forward or backward, and the locking portion can be inserted between two adjacent protrusions on one side of the corresponding stop portion or between the protrusion and the stop portion to achieve locking, thereby facilitating personnel operation and providing protection for the cultivation of microorganisms.

[0021] The utility model is specifically introduced below in conjunction with the accompanying drawings and embodiments.
[0022] This embodiment provides a bidirectionally lockable culture dish, such as Figure 1-3 As shown, it includes a dish cover 1 and a dish body 2, three stoppers 3 are formed on the outer circumference of the opening of the dish body 2, and the non-connecting surfaces of the stoppers 3 and the dish body 2 are square structures. Two protrusions 4 are formed on the dish body 2 located on both sides of each stopper 3, and the distance between the protrusion 4 and the vertical center line of the dish body 2 is greater than the distance between the stoppers 3 and the vertical center line of the dish body 2.
[0023] The inner circumference of the dish cover 1 has three anti-slipping parts 5 corresponding to the stopper 3 and arranged horizontally. Each anti-slipping part 5 forms a gap with the top of the dish cover 1 for the stopper 3 and the protrusion 4 to be screwed in. The height of the gap is close to the thickness of the stopper 3 and the protrusion 4 to ensure the sealing effect after locking. At the same time, a locking part 6 is formed on the inner side of the dish cover 1 in each gap, and the locking part 6 is located in the gap on the upper side of the middle part of the anti-slipping part 5.
[0024] The stopper 3, the protrusion 4 and the dish body 2 are integrally formed, the anti-slip portion 5, the locking portion 6 and the dish cover 1 are also integrally formed, and the entire culture dish is made of polystyrene. At the same time, in order to facilitate locking, the outer edges of the protrusion 4 and the locking portion 6 are both arc-shaped.
[0025] See also Figure 4-5 As shown, the locking portion 6 cooperates with the anti-slip portions 5 on both sides and the dish cover 1 to form an area where the stopper 3 and the protrusion 4 can be embedded, whether the dish cover 1 is rotated forward or backward. When the dish cover 1 needs to be locked with the dish body 2, the dish cover 1 is covered on the dish body 2, and then the dish cover 1 is rotated in any direction. Since the culture dish is made of polystyrene, it has a certain elasticity and can be deformed to a certain extent. During the rotation process, the locking portion 6 will first come into contact with the protrusion 4 on the front side of the stopper 3 and slightly twist, so that the locking portion 6 can be inserted between the two adjacent protrusions 4 during the continued rotation process; when further force is applied to rotate the dish cover 1, the locking portion 6 will come into contact with the other protrusion 4 and twist and deform, so that the locking portion 6 can be inserted between the protrusion 4 and the stopper 3 to achieve locking.
[0026] The above is only a preferred implementation of the utility model patent. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model patent. These improvements and modifications should also be regarded as the protection scope of the utility model patent.
