Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present invention is a spiral cultivation tube for aerobic and anaerobic integrated culture, which includes a tube body 1 and a cover body 2 mounted on the tube body 1; a first main thread 4 and a first auxiliary thread 6 are arranged at the upper part of the pipe body 1, the first main thread 4 is arranged above the first auxiliary thread 6, and the first main thread 4 and the first auxiliary thread 6 are both gradually broken threads; correspondingly, the inner wall of the cover body 2 is also provided with a second main thread 5 and a second auxiliary thread 7, the second main thread 5 is arranged above the second auxiliary thread 7, the first main thread 4 needs to be matched with the second main thread 5 on the inner wall of the cover body 2, and the first auxiliary thread 6 on the pipe body 1 needs to be matched with the second auxiliary thread 7; different from the threads on the pipe body 1, the second main thread 5 and the second auxiliary thread 7 on the inner wall of the cover body 2 are continuous threads; meanwhile, in order to ensure the sealing, a sealing ring 3 matched with the upper end of the pipe body 1 is additionally arranged in the cover body 2. Preferably, the lower portion of the tube body 1 is designed to be a circular arc spherical surface shape as a culture tube in the prior art, and the sealing ring 3 and the cover body 2 can be designed to be an integrated structure and integrally formed by injection molding of HDPE, so as to help sealing and prevent impurities from entering the tube body 1 to affect sample culture.

Further, the external diameter of the first main thread 4 can be designed to be smaller than the internal diameter of the second auxiliary thread 7, so that in the use of the culture tube, the first main thread 4 on the tube body 1 can pass through the second auxiliary thread 7 on the inner wall of the cover body 2 without hindrance and directly cooperate with the second main thread 5, and under the cooperation effect of the first main thread 4 and the second main thread 5, the upper end part of the tube body 1 is in close contact with the sealing ring 3 to form a seal.

In this embodiment, by adding the gradually broken first main thread 4 and first auxiliary thread 6 on the upper portion of the tube body 1 and adding the second main thread 5 and second auxiliary thread 7 on the inner wall of the cover body 2, the cover body 2 can be installed on the tube body 1 through threads, so as to conveniently cover and remove the cover body 2, and avoid the sample in the tube body 1 from spilling due to too large force, and the seal ring 3 in the cover body 2 can also ensure sealing, so that the sample in the tube body can be cultured anaerobically.

Referring to fig. 2 and 3, in practical use, the tube 1 can be directly installed on the tube 1 by threading, and since the first main thread 4 and the first auxiliary thread 6 on the tube are both of a gradual breaking type, when the cap 2 is rotated to match the first main thread 4 and the second main thread 5 on the tube 1, since the first main thread 4 and the first auxiliary thread 6 are both of a gradual breaking structure, [ U1] the upper end of the tube 1 is not in contact with the sealing ring 3, external air can enter the tube 1 through the gap between the gradual breaking threads through the opening at the upper part of the tube 1, so as to realize aerobic culture, as shown in fig. 2; when anaerobic culture is required, the cover body 2 is continuously rotated, the first main thread 4 is kept to be matched with the second main thread 5, and finally the pipe body is screwed into the state shown in figure 3, at the moment, the upper end part of the pipe body 1 is tightly contacted with the sealing ring 3, so that sealing is realized, external air is prevented from entering the pipe body 1, and anaerobic culture is realized. And at this moment, under the matching action of the first main thread 4 and the second main thread 5, the end part of the pipe body 1 and the sealing ring are always kept in a close contact state, so that the sealing stability is ensured. In other words, in the utility model, the switch between aerobic culture and anaerobic culture can be realized by rotating the cover body 2, and the device can be used for two purposes and is convenient to operate.

In addition to the foregoing, it should be noted that reference throughout this specification to "one embodiment," "another embodiment," "an embodiment," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment described generally throughout this application. The appearances of the same phrase in various places in the specification are not necessarily all referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with any embodiment, it is submitted that it is within the scope of the invention to effect such feature, structure, or characteristic in connection with other embodiments.
