Description

Technical Field

[0001] The utility model provides a test tube box for detection, which relates to the technical field of microorganism detection. Background Technique

[0002] GB / T 4789.27-2008 "Microbiological examination of food hygiene - Examination of antibiotic residues in fresh milk" adjusts the detection method of antibiotics in fresh milk, changing the detection method from a test kit plus nutrient tablets to preparing a culture medium containing spores of test strains in small test tubes. The examination of antibiotic residues in fresh milk includes two methods: the Streptococcus thermophilus inhibition method and the Bacillus stearothermophilus inhibition method. The test procedures of both methods include water bath cultivation. The small test tubes for cultivation are generally plastic tubes, which will float on the water surface when directly placed in water and are also prone to floating on the test tube rack, making the culture medium unable to be fully immersed in hot water, affecting the final reaction and detection effect.

[0003] The existing test tube racks for water bath heating are not suitable for water bath cultivation of plastic small test tubes. When plastic small test tubes are placed on ordinary test tube racks, they are prone to floating and cannot be fully immersed in hot water. For ordinary test tube racks with lids, there are technical problems such as inconvenient height adjustment, and the structure of test tube racks with adjustable height is relatively complex. Content of the Utility Model

[0004] The utility model provides a test tube box for detection, which solves the technical problems that plastic small test tubes are prone to floating during water bath cultivation in the prior art and the structure of a lid-covered test tube rack with adjustable height is relatively complex.

[0005] The utility model is realized as follows: the height of the box lid is less than the height of the box body. Notches are provided on both sides of the box lid. At least two vertically extending limiting strips are provided on the vertical inner surface of the box lid. All the limiting strips are arranged in parallel. Limiting protrusions are provided at the bottom ends of all the limiting strips. Limiting grooves corresponding to the positions of the limiting strips are provided on the outer side of the box body. The number of the limiting grooves is the same as the number of the limiting strips. A plurality of limiting concave holes adapted to the limiting protrusions are provided on all the limiting grooves. The adjacent limiting concave holes on different limiting grooves are located on the same horizontal line. A plurality of test tube slots are provided in the box body, and through holes are provided at the bottoms of the test tube slots.

[0006] As a further preference, the lengths of all the limiting strips are not completely the same.

[0007] As a further preference, the number of the limiting strips is three, and the lengths of the three limiting strips change gradually.

[0008] As a further preference, the lengths of all the limiting grooves change gradually.

[0009] As a further preference, one limiting concave hole is provided in the shorter limiting groove, two limiting concave holes are provided in the longer limiting groove, and three equally spaced limiting concave holes are provided in the longest limiting groove.

[0010] As a further preference, all the limiting strips and all the limiting grooves are axially symmetric, and the length change trends of the limiting strips on both sides of the symmetry center line are the same, and the length change trends of the limiting grooves on both sides of the symmetry center line are the same.

[0011] As a further preference, the number of the limiting strips is five, the number of the limiting grooves is five, one limiting concave hole is provided in the shortest limiting groove, two limiting concave holes are provided in the longer limiting groove, and three equally spaced limiting concave holes are provided in the longest limiting groove.

[0012] As a further preference, the limiting strip is made of plastic.

[0013] As a further preference, the diameter of the through hole is smaller than the diameter of the bottom of the test tube.

[0014] As a further preference, vertical strips are provided at positions near the four corners on the inner surface of the box cover, and vertical grooves corresponding to the vertical strips are provided on the outer side of the box body.

[0015] The beneficial effects of the present utility model are as follows: The test tube box for detection realizes the height adjustment inside the test tube box body by adjusting the connection between the limiting protrusions of the limiting strips and the limiting concave holes at different horizontal positions, so as to accommodate test tubes of different heights. The adjustment method is simple and convenient to operate. The test tube box for detection provided by the present utility model is not only applicable to the detection of small test tubes, but also applicable to the detection of larger test tubes, and has a wide range of uses. By increasing the number of the limiting strips and the limiting grooves, the height stability of the test tube box for detection can be increased, and the number of the limiting concave holes on the limiting grooves of different lengths is inconsistent. When small test tubes are placed in the box body, the closing depth of the box cover is deeper, the vertical strips at the four corners of the box cover are in full contact with the box body and are not easy to float up, and the limiting protrusions on the limiting strips only need to cooperate with a small number of limiting concave holes at the bottom of the limiting grooves; when larger test tubes are placed in the box body, the closing depth of the box cover is shallower, the vertical strips at the four corners of the box cover cannot be in full contact with the box body, and at this time, the limiting protrusions on the limiting strips cooperate with multiple limiting concave holes on the limiting grooves to prevent the box cover from falling off during the water bath heating process.
