Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of amplification devices, in particular to an amplification device for nucleic acid detection. Background Art
[0002] Nucleic acid testing is a method used to detect specific DNA fragments in samples, including PCR testing, LAMP testing, and CRISPR testing. Most existing nucleic acid tests often use PCR testing. PCR is the abbreviation of polymerase chain reaction, which is an enzymatic chemical reaction that can amplify the target gene to be tested in a test tube by 500,000 times or even millions of times in a very short period of time, greatly improving the sensitivity of genetic diagnosis and reducing the difficulty of analysis. When conducting PCR testing, staff need to place the PCR plate in the amplification instrument to amplify the gene.
[0003] When the thermal amplifier is in use, the staff needs to turn the heat cover adjustment knob to adjust the height of the heat cover to ensure sufficient heating of the sample. However, the existing heat cover adjustment knob is often exposed on the top of the sealing cover, which is easy to be accidentally touched during the experiment, causing the heat cover adjustment knob to rotate, thereby causing the heat cover height to change, affecting the heating efficiency of the device, reducing the amplification effect of the device, and even having a certain impact on the accuracy of subsequent detection processes. Utility Model Content
[0004] The purpose of the utility model is to provide an amplification device for nucleic acid detection to solve the technical problems mentioned in the above background technology.
[0005] The technical problem to be solved by the utility model can be achieved through the following technical solutions:
[0006] An amplification device for nucleic acid detection, comprising an amplifier body, a sealing cover rotatably connected to the top of the amplifier body, a base connected to the top of the sealing cover, a heat cover adjustment knob arranged on the top of the base, an outer peripheral ring connected to the top of the base surrounding the outer periphery of the heat cover adjustment knob, and a magnetic ring connected to the inner wall of the outer peripheral ring surrounding the inner periphery;
[0007] The heat cover adjustment knob is symmetrically provided with T-slots inside, a communicating movable slot is provided at the bottom of the T-slot, a wedge block is transversely provided inside the T-slot, a push button is connected to one side of the wedge block, an active rod is vertically provided inside the T-slot, a lifting rod transversely provided inside the movable slot is connected to the bottom end of the active rod, a spherical head is connected to the top of the active rod, a return spring is provided on the outside of the active rod, and one end of the lifting rod passing through the movable slot is connected to a magnetic arc plate.
[0008] As a further solution of the utility model: the push button passes through one end of the T-slot, the spherical head is located below the wedge block, and the head and tail ends of the reset spring are respectively connected to the bottom wall of the T-slot and the bottom of the spherical head.
[0009] As a further solution of the utility model: a display screen is arranged on the front of the amplifier body, and heat dissipation holes are arranged on both sides of the amplifier body.
[0010] As a further solution of the utility model: a data terminal is arranged on the back of the amplifier body, and a power terminal is arranged on the back of the amplifier body, and the power terminal is located on one side of the data terminal.
[0011] As a further solution of the utility model: a protective cover is rotatably connected to the top of the base, and the protective cover is located on one side of the outer ring.
[0012] Beneficial effects of the utility model:
[0013] When the utility model rotates the heat cover adjusting knob, the staff needs to press the push button inwardly, so that the magnetic arc plate moves downward and is offset from the magnetic ring, thereby releasing the limit on the heat cover adjusting knob. After the rotation is completed, the magnetic arc plate and the magnetic ring are loosened, and the magnetic arc plate and the magnetic ring are re-adsorbed together to fix the heat cover adjusting knob. Therefore, even if an accidental touch occurs, it is not easy to cause the heat cover adjusting knob to rotate, thereby further ensuring the stable operation of the device and the heating efficiency of the device, and improving the amplification effect of the device.
