DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The present utility model will be further described below in conjunction with the drawings and embodiments. The implementation manners of the present utility model include but are not limited to the following embodiments. Embodiment 1

[0028] As Figures 1-5As shown in the figure, the portable rapid nucleic acid extraction device provided by the present utility model includes: a housing 1, in which a magnetic rod 5 and a magnetic rod sleeve 6 are installed. The structures of the magnetic rod 5 and the magnetic rod sleeve 6 are the same as those disclosed in CN209906801U and will not be elaborated here. A controller 2 and a rotatable handle 3 are installed on the top of the housing 1. Through the handle 3, the device can be conveniently lifted, making it more convenient to use. There are access openings 4 on both sides of the housing 1, and a test tube support mechanism is provided inside the housing 1; the test tube support mechanism includes a track frame 7 connected to the housing 1. Two translatable test tube platforms 8 are installed on the track frame 7. The test tube platforms 8 also adopt the structure disclosed in CN209906801U and are used to place test tubes for nucleic acid extraction. A driving motor 9 for driving the test tube platforms 8 to translate is installed on one side of the track frame 7. It should be noted that a part of the track frame 7 extends out from the access opening 4 (about one-third). The controller 2 can control the driving motor 9. During use, the test tubes for nucleic acid extraction are placed on the test tube platforms 8. By controlling the driving motor 9 to start through the controller 2, the two test tube platforms 8 are driven to translate, so that one of the test tube platforms 8 moves below the magnetic rod sleeve 6. The magnetic rod 5 and the magnetic rod sleeve 6 descend into the test tube, and the magnetic rod sleeve 3 oscillates to lyse the nucleic acid sample in the test tube, facilitating the subsequent extraction of nucleic acid. During this process, the test tube platform 8 outside the housing 1 is in an idle state. Taking advantage of this period of time, the subsequent test tubes can be placed on this test tube platform 8, thus saving time. When another test tube platform 8 moves out from the other access opening 4, this test tube platform 8 moves into the housing 1, and the nucleic acid sample in the test tube on this test tube platform 8 can continue to be lysed. Moreover, taking advantage of this idle time, the test tube on another test tube platform 8 is replaced with a test tube to be operated. Thus, the two test tube platforms 8 take turns to enter the housing 1, enabling continuous operation and improving the operation efficiency of the device.

[0029] By setting the housing 1, the handle 3, the access openings 4, the magnetic rod 5, the magnetic rod sleeve 6 and the test tube support mechanism, and using the driving motor to drive the two test tube platforms 8 to take turns to enter the housing 1 for operation, the test tubes are replaced synchronously during the operation period of the device, which can improve the operation efficiency of the device and can conveniently lift the device for transfer. Embodiment 2

[0030] As Figures 3-4As shown in the figure, a support plate 10 is slidably installed inside the track frame 7. The test tube platform 8 is installed on the top of the support plate 10. A rack 11 is installed at the bottom of the support plate 10. A gear shaft 13 is installed at the bottom of the rack 11 in a meshing manner. A connecting shaft 12 is installed at the end of the gear shaft 13. The connecting shaft 12 is rotatably connected to the track frame 7 through a bearing. And the output shaft of the driving motor 9 is connected to the connecting shaft 12 through a coupling. When in use, the driving motor 9 is started to make its output shaft rotate forward / backward, thereby making the connected connecting shaft 12 rotate. The rotation of the connecting shaft 12 drives the gear shaft 13 to rotate. The gear shaft 13 drives the rack 11 engaged therewith to move. The rack 11 drives the support plate 10 to translate, thereby making the test tube platform 8 on the top of the support plate 10 move. The test tube platform 8 moves out of or into the housing 1.

[0031] By providing the support plate 10, the rack 11, the connecting shaft 12 and the gear shaft 13, it is convenient for the driving motor 9 to drive the test tube platform 8 to translate. Embodiment 3

[0032] As Figure 1 shown, a detachable protective cover 15 is installed on the track frame 7, and a liftable sealing door 16 is installed outside the entrance / exit 4. When in use, as Figure 1 shown, in this state, through the protective cover 15 and the sealing door 16, the device can be enclosed to prevent dust from entering the housing 1. When the device needs to be used, the sealing door 16 is pulled up and the protective cover 15 is removed, so that both ends of the track frame 7 are in an exposed state, which is convenient for adding and removing test tubes to / from the test tube platform 8.

[0033] By providing the protective cover 15 and the sealing door 16, it is convenient to enclose and protect the exposed part of the track frame 7 in a timely manner. Embodiment 4

[0034] As Figure 3 and Figure 5 shown, a card slot 17 is provided on the track frame 7. The card slots 17 are symmetrically arranged. A card strip 18 adapted to the card slot 17 is provided on the inner side of the protective cover 15. When in use, the card strip of the protective cover 15 is inserted into the card slot 17 and slides, thereby clamping and installing the protective cover 15 on the track frame 7. In addition, pull rods 19 are installed on both sides of the protective cover 7. By holding the pull rods 19, it is convenient to push and pull the protective cover 15, which is convenient for the installation and disassembly of the protective cover 15.

[0035] By providing the card slot 17 and the card strip 18, it is convenient to clamp and install the protective cover 15 on the track frame 7, which is convenient for the disassembly and assembly of the protective cover 15. Embodiment 5

[0036] As Figure 5As shown in the figure, a limiting groove 20 is formed at the top of the protective cover 15, and the bottom end of the sealing door 16 can be inserted into the limiting groove 20. During use, the protective cover 15 is snap-connected to the track rack 7, so that the limiting groove 20 on the protective cover 15 moves below the sealing door 16, and then the sealing door 16 is pulled downward to embed the top end thereof into the limiting groove 20, thereby limiting the protective cover 15 and preventing the protective cover 15 from falling off the track rack 7.

[0037] By forming the limiting groove 20 at the top of the protective cover 15, the protective cover 15 can be limited to prevent the protective cover 15 from falling off the track rack 7. Embodiment 6

[0038] As Figure 4 shown in the figure, a sponge pad 14 is laid and installed below the test tube platform 8, and the bottom of the test tube is supported by the sponge pad, which has a shock-absorbing effect and plays a role in protecting the test tube.

[0039] By installing the sponge pad 14 below the test tube platform 8, the test tube can be protected.

[0040] Working principle: During use, the test tube for nucleic acid extraction is placed on the test tube platform 8. The controller 2 is used to control the driving motor 9 to start, so as to drive the two test tube platforms 8 to translate, so that one of the test tube platforms 8 moves below the magnetic rod sleeve 6. The magnetic rod 5 and the magnetic rod sleeve 6 descend into the test tube, and the magnetic rod sleeve 3 oscillates to lyse the nucleic acid sample in the test tube, which is convenient for the subsequent extraction of nucleic acid. During this process, the test tube platform 8 located outside the housing 1 is in an idle state. Taking advantage of this period of time, the subsequent test tubes can be placed on this test tube platform 8, thereby saving time. When the other test tube platform 8 moves out from the other side entrance and exit 4, this test tube platform 8 moves into the housing 1, and the nucleic acid sample in the test tube on this test tube platform 8 can continue to be lysed. Moreover, taking advantage of this idle time, the test tube on the other test tube platform 8 is replaced with a test tube to be operated. Thus, the two test tube platforms 8 take turns to enter the housing 1, and continuous operation can be realized, improving the operation efficiency of the device.
