Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to biological experiment consumables, in particular to a centrifuge tube with an independent cover. Background Art
[0002] Polymerase Chain Reaction (PCR) technology is widely used in the field of biology. Usually, PCR reactions need to be carried out in PCR tubes.
[0003] After extensive searching, I found that the Chinese patent publication number is CN210065760U, which discloses a PCR tube and PCR plate for PCR detection of plant pathogenic bacteria. The PCR tube includes a tube body with a closed bottom and an open top, and a tube cover inserted at the tube mouth of the tube body. The tube cover includes a connecting portion that extends into the interior of the tube body when the cover is closed, and a cap portion located outside the tube body. The outer surface of the connecting portion near the cap portion is provided with an external thread, and the inner surface of the tube body near the tube mouth is provided with an internal thread. The inner surface of the tube body is provided with a soft rubber layer circumferentially below the internal thread. The soft rubber layer surrounds the tube body to form a sleeve-like structure. When the tube cover is closed, the connecting portion extends into the soft rubber layer. Because the tube cover and tube body of the PCR tube are connected by threads and sealed with a soft rubber layer, the double seal can prevent the tube cover from detaching, making the seal more stable, avoiding expansion and loosening of the tube cover after the amplification reaction, and avoiding the occurrence of false positives. At the same time, the tube cover can be opened and closed by twisting the tube cover with relatively little force, which is relatively labor-saving.
[0004] In summary, when the existing PCR tube is in use, the upper cover and the tube body are connected by threads, which enhances the firmness of the upper cover installation, but the installation and removal of the upper cover is time-consuming and labor-intensive.
[0005] In view of the above-mentioned defects, the present designer actively carried out research and innovation in order to create a centrifuge tube with an independent cover to make it more valuable for industrial use. Utility Model Content

[0009] An annular plug protruding upward is provided on the upper cover, and a buckle is provided on the upper cover on the left side of the plug;
[0010] An upper mounting cavity and a lower mounting cavity are sequentially arranged in the upper mounting seat from top to bottom, and an inner tube cavity is arranged in the tube body below the lower mounting cavity;
[0011] The upper cover is closed on the upper mounting seat, the plug passes through the upper mounting cavity and is installed in the lower mounting cavity, and the buckle is buckled on the right bottom of the upper mounting seat.
[0012] As a further improvement of the present invention, a scale layer is provided on the tube body.

[0017] As a further improvement of the present invention, a sealing groove is provided near the top of the plug, and a sealing ring is installed in the sealing groove.
[0018] As a further improvement of the present invention, the tube body, the upper mounting seat, the bent connection portion, the upper cover and the plug are all made of PP material.
[0019] By means of the above solution, the present invention has at least the following advantages:
[0020] When the upper cover of the utility model is closed on the upper mounting seat, the plug passes through the upper mounting cavity and is installed in the lower mounting cavity, and then the buckle is buckled on the upper mounting seat. Under the premise of ensuring the firmness of the upper cover, the installation and disassembly of the upper cover is relatively convenient;
