Technical Field

The invention relates to the technical field of plant tissue culture, in particular to a circular plant tissue culture box.

Background

The tissue culture technique is a technique in which living isolated organs (e.g., roots, stems, leaves, stem segments, protoplasts), tissues or cells are placed in a culture medium under artificially created aseptic conditions and placed in an appropriate environment for continuous culture to obtain cells, tissues or individuals. The technology is widely applied to agriculture and biological and medical research.

Disclosure of Invention

For this reason, need provide a circular plant group and cultivate box with earth, the device reduces the upper cover closure and opens the obstacle that the in-process met through the rational arrangement and the cooperation function of each structure, and the simple operation nature promotes greatly, improves work efficiency, avoids the upper cover that drops after the filter membrane sterilization and leads to scrapping, reduces the waste of material, practices thrift the cost, and is difficult for producing the comdenstion water in the container, and the plant can more evenly absorb light and reduce the pollution that the comdenstion water caused.

In order to achieve the purpose, the invention provides a circular plant tissue culture box which comprises an upper cover and a base, wherein the upper cover and the base are rotatably connected, and a limiting device which is matched with each other, limits a rotating angle and aligns the rotating angle is arranged at the joint of the upper cover and the base. Stop device's setting reduces the upper cover and closes and open the obstacle that the in-process meets, and the simple operation nature promotes greatly, improves work efficiency.

Furthermore, stop device is including setting up in at least one arch of upper cover inner wall edge and setting up in at least one breach at base outer wall edge, at least one arch and at least one breach shape looks adaptation. The cooperation of arch and breach makes the upper cover can fix on the base, and aims at the arch breach rotation can be more accurate guarantee upper cover and base be connected.

Furthermore, the upper cover and the base are rotatably connected through threads, the protrusions are arranged on internal threads on the edge of the inner wall of the upper cover, and the notches are arranged on external threads on the edge of the outer wall of the base. Threaded connection makes, upper cover and base connection convenient and fast more, and the cooperation setting of arch and breach for only need rotate less than 180 degrees and can fix when rotating at the bottom of the upper cover through the screw thread and connecting.

Furthermore, the width of the internal thread and the external thread is the relative displacement distance of the upper cover and the base which rotate for one circle, and the rotation angle of the bulge relative to the horizontal plane is less than 180 degrees. The thread rotating distance is shortened to one circle, so that the operation convenience is greatly improved, and the working efficiency is improved.

Furthermore, the number of the limiting devices is two, and the two limiting devices are oppositely arranged at the joint of the upper cover and the base. The number of the limiting devices is two, so that the rotating angles of the upper cover and the base are limited to a greater extent.

Furthermore, the number of the limiting devices is four, and the four limiting devices are uniformly distributed at the joint of the upper cover and the base for a circle. The number of the limiting devices is four, so that the rotation angles of the upper cover and the base are limited to a greater extent.

Furthermore, the top of the upper cover is provided with an air hole, and a filter membrane is embedded in the air hole of the upper cover. The arrangement of the air holes enables air to flow in the upper cover, and the filter membrane prevents external moisture and mixed bacteria from entering.

Furthermore, a plurality of positioning bulges are arranged at the bottom of the base. The base can be stabilized in the bellied setting of location, prevents the higher cultivation frame surface of base contact temperature simultaneously to arouse the inside condensation drop that appears of container, the drop of water condenses and can lead to the inside plant of container to receive the illumination inhomogeneous at upper cover internal surface.

Furthermore, the vertical section of the upper cover is a trapezoidal cross section with a small upper part and a large lower part, and the vertical section of the base is a trapezoidal cross section with a large upper part and a small lower part. The arrangement of the structure enables a large operation area to be formed between the upper cover and the base, and then the operation is carried out by personnel.

Furthermore, the cross sections of the upper cover and the base are circular cross sections. The circular cross-section arrangement is such that the upper cover and base facilitate a threaded connection.

Different from the prior art, the technical scheme has the following beneficial effects:

1. according to the invention, the limiting device is arranged at the joint of the upper cover and the base, the inner thread of the upper cover at the position corresponding to the limiting device is provided with the bulge, the thread at the position corresponding to the base is provided with the notch, the upper cover and the base can be clamped only by rotating less than 180 degrees at the indication position corresponding to the closing position, and the number of turns of the thread at the joint of the cover and the base is reduced.

2. According to the invention, the filter membrane is directly embedded on the air holes, so that the upper cover is prevented from being discarded due to the falling off of the filter membrane after sterilization.

3. The bottom of the container base is provided with the positioning bulge, so that the base is prevented from contacting the surface of the culture shelf with higher temperature, condensed water drops are generated in the container, and the condensation of the water drops on the inner surface of the upper cover can cause uneven illumination of plants in the container and easy plant pollution.
