[0002] Gene amplification instrument is a high-precision and high-efficiency biotechnology instrument, which is mainly used to amplify DNA or RNA molecules to obtain high-quality gene sequence information. It is an important tool for gene amplification experiments in the fields of molecular biology, medicine, food industry, forensic science, biotechnology, environmental science, microbiology, clinical diagnosis, epidemiology, genetics, gene chip, gene detection, gene cloning and gene expression.
[0003] Generally, when a gene thermal cycler is used, the lid is first opened, and then the container is placed inside the instrument. Then the lid is closed. During the gene amplification process, the PCR tube needs to be heated. After the reagent in the PCR tube evaporates due to heat, a certain air pressure will be formed in the PCR tube. The lid of the instrument is easily popped open, which will cause aerosol leakage and pollution. In severe cases, it may even cause the entire laboratory to stop production. Therefore, it needs to be improved and optimized. Utility Model Content

[0027] like Figures 1 to 5 As shown, the utility model provides a gene amplification instrument with a thermal cover lock, comprising a bottom shell 1, a top shell 2, and a cover 3, wherein the top shell 2 is movably arranged above the bottom shell 1, and the cover 3 is hinged above the top shell 2;
[0028] A fixing mechanism, fixedly arranged on one side of the top shell 2;
[0029] The fixing mechanism includes a bottom plate 14 fixedly arranged on one side of the inner part of the top shell 2, a telescopic rod 12 is fixedly installed on the top of the bottom plate 14, a rotating frame 9 is fixedly installed on the top of the telescopic rod 12, a spring 13 is fixedly installed on the top of the bottom plate 14, the spring 13 is elastically connected between the rotating frame 9 and the bottom plate 14, a latch 10 is fixedly installed on one side of the top shell 2, the other end of the latch 10 movably passes through both sides of the rotating frame 9, a fixing frame 8 is fixedly installed below the rotating frame 9, a fixing plate 7 is fixedly installed below the cover 3, the fixing frame 8 is movably connected to the fixing plate 7, and a handle 11 is fixedly installed above the rotating frame 9.
[0030] When the staff uses it, the staff first presses the handle 11, and when the handle 11 is pressed, it moves downward. When the handle 11 moves downward, it drives one end of the rotating frame 9 to rotate downward around the latch 10. When one end of the rotating frame 9 rotates downward, it presses the spring 13 downward. When the spring 13 is pressed, it drives the upper end of the telescopic rod 12 to move downward. As one end of the rotating frame 9 moves downward, the other end of the rotating frame 9 moves upward. When the other end of the rotating frame 9 moves upward, it drives the fixed frame 8 to move upward. At this time, the cover 3 can be opened around the connection between the cover 3 and the top shell 2.
[0031] By pressing the handle 11, the handle 11 will move downward when pressed, which will drive one end of the rotating frame 9 to rotate downward around the latch 10, and the spring 13 will be pressed downward, and the other end of the rotating frame 9 will move upward, which will drive the fixed frame 8 to move upward. At this time, the lid 3 can be opened around the connection between the lid 3 and the top shell 2. Compared with the traditional device, the device can improve the stability of the lid 3 when closing through the fixing mechanism, avoid the lid 3 being opened due to excessive internal pressure, and improve the working efficiency of the device.
[0032] Among them, also include:
[0033] The disassembly mechanism is fixedly arranged on both sides of the bottom shell 1;
[0034] The disassembly mechanism includes a fixing block 15 fixedly arranged on both sides of the top shell 2, a groove 16 is opened inside the fixing block 15, a knob 19 is rotatably installed inside the fixing block 15, a threaded rod 18 is rotatably installed above the knob 19, a fixing block 20 is fixedly installed on the side of the bottom shell 1, the fixing block 20 is located below the fixing block 15, the threaded rod 18 movably passes through the knob 19 and the fixing block 20, the threaded rod 18 and the knob 19 are threadedly sleeved, and a limiting plate 17 is fixedly installed on the top of the threaded rod 18.
[0035] When the staff uses it, they first turn the knob 19. When the knob 19 is turned, since there is a thread at the connection between the knob 19 and the threaded rod 18, and the up and down movement of the knob 19 is restricted by the fixed block 15, the rotation of the knob 19 will drive the threaded rod 18 to move upward. When the threaded rod 18 moves upward, it will drive the limit plate 17 to move upward along the inner wall of the groove 16. When one end of the threaded rod 18 is completely moved out of the fixed block 20, the staff can separate the top shell 2 from the bottom shell 1 and replace the bottom shell 1 or the top shell 2.
[0036] By turning the knob 19, the threaded rod 18 will be driven to move upward as the knob 19 is turned, thereby driving the limit plate 17 to move upward along the inner wall of the groove 16. When one end of the threaded rod 18 is completely moved out of the interior of the fixed block 20, the staff can separate the top shell 2 from the bottom shell 1 and repair the interior. Compared with the traditional device, the device can quickly open the outer shell of the device and quickly replace the internal parts when the internal parts of the device are damaged through the disassembly mechanism, thereby improving the working efficiency of the device.
[0037] The top shell 2 also includes a screen 4 fixedly mounted on one side of the top shell 2 , and a button 5 fixedly mounted on the side of the bottom shell 1 .
[0038] The operation of the entire device can be controlled by buttons 5, and the internal data can be displayed through screen 4.
[0039] There are two groups of disassembly mechanisms, which are evenly distributed on both sides of the top shell 2 .
[0040] When the bottom shell 1 and the top shell 2 are fixed, the stability of the fixing of the bottom shell 1 and the top shell 2 is improved, thereby improving the working efficiency of the device.
[0041] The bottom shell 1 further includes a rectangular block 6 fixedly arranged on the inner bottom of the bottom shell 1 , and a second groove 21 is formed on the upper side of the rectangular block 6 .
[0042] The sample tube can be placed inside the second groove 21 and fixed, thereby improving the working efficiency of the device.
[0043] There are three telescopic rods 12 , which are evenly distributed above the bottom plate 14 .
[0044] This improves the stability of the cover 3 and increases the downward pressure of the fixing frame 8 when the cover 3 is fixed.
[0045] There are three springs 13 , which are evenly distributed above the bottom plate 14 .
[0046] The stability of the cover 3 is improved, the downward pressure of the fixing frame 8 is increased, and the working efficiency of the device is improved.
[0047] The rectangular block 6 is movably connected to the top shell 2 and fixedly connected to the bottom shell 1 .
[0048] The top shell 2 and the bottom shell 1 can be movably connected and disassembled.
[0049] The working principle and use process of this utility model:
[0050] When the staff uses it, the staff first presses the handle 11, and when the handle 11 is pressed, it moves downward. When the handle 11 moves downward, it drives one end of the rotating frame 9 to rotate downward around the latch 10. When one end of the rotating frame 9 rotates downward, it presses the spring 13 downward. When the spring 13 is pressed, it drives the upper end of the telescopic rod 12 to move downward. As one end of the rotating frame 9 moves downward, the other end of the rotating frame 9 moves upward. When the other end of the rotating frame 9 moves upward, it drives the fixed frame 8 to move upward. At this time, the cover 3 can be opened around the connection between the cover 3 and the top shell 2.
[0051] When the staff uses it, they first turn the knob 19. When the knob 19 is turned, since there is a thread at the connection between the knob 19 and the threaded rod 18, and the up and down movement of the knob 19 is restricted by the fixed block 15, the rotation of the knob 19 will drive the threaded rod 18 to move upward. When the threaded rod 18 moves upward, it will drive the limit plate 17 to move upward along the inner wall of the groove 16. When one end of the threaded rod 18 is completely moved out of the fixed block 20, the staff can separate the top shell 2 from the bottom shell 1 and replace the bottom shell 1 or the top shell 2.
