Description

Technical Field

[0001] The utility model relates to the technical field of biological analysis and detection, in particular to a nucleic acid detection and extraction plate. Background Art

[0002] The substance of nucleic acid testing is the nucleic acid of the virus. Nucleic acid testing can determine whether the person being tested is infected with a foreign virus by looking for the nucleic acid of the foreign invading virus in the patient's respiratory specimens, blood or feces. In order to facilitate nucleic acid testing of the collected samples, a nucleic acid testing extraction plate is required to place the nucleic acid extraction test tube.

[0003] In the prior art, a plurality of nucleic acid extraction test tubes are placed in a nucleic acid detection extraction plate. When a nucleic acid extraction test tube needs to be taken out individually, it is inconvenient to grab a nucleic acid extraction test tube individually because the nucleic acid extraction test tubes are placed relatively closely and the space between adjacent nucleic acid extraction test tubes is small. Therefore, it is inconvenient for medical staff to take a nucleic acid extraction test tube individually. Therefore, a nucleic acid detection extraction plate is proposed to solve the above problem. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the shortcomings of the prior art, the utility model provides a nucleic acid detection extraction plate, which has the advantages of being easy to take out a certain nucleic acid extraction test tube from the nucleic acid detection extraction plate full of nucleic acid extraction test tubes, etc., and solves the problem in the prior art that a plurality of nucleic acid extraction test tubes are placed in the nucleic acid detection extraction plate. When a certain nucleic acid extraction test tube needs to be taken out individually, it is inconvenient to grab a certain nucleic acid extraction test tube individually because the nucleic acid extraction test tubes are placed relatively closely and the space between adjacent nucleic acid extraction test tubes is small. As a result, it is inconvenient for medical staff to take out a certain nucleic acid extraction test tube individually.

[0006] (II) Technical solution

[0007] The utility model solves the above-mentioned technical problems with the following technical solutions: A nucleic acid detection and extraction plate comprises a rectangular shell and a nucleic acid extraction test tube, characterized in that: a grid through-hole plate which is symmetrically distributed on the left and right and flush with the top of the rectangular shell is fixedly connected inside the rectangular shell, the grid through-hole plate is adapted to the nucleic acid extraction test tube, a first partition which is flush with the top of the rectangular shell is fixedly connected on the opposite side of the grid through-hole plate, a second partition located below the first partition is fixedly connected on the opposite side of the grid through-hole plate, the left and right walls of the inner cavity of the rectangular shell are fixedly connected with slide grooves which are equidistantly distributed in the longitudinal direction and adapted to each other, the opposite sides of the slide grooves which are adapted to each other are provided with the same lifting assembly which is slidably connected to the first partition and adapted to the nucleic acid extraction test tube, a pressing assembly which is equidistantly distributed in the longitudinal direction and extends to the bottom of the first partition is provided on the top of the first partition, a transmission assembly which is threadedly connected to the first partition and extends to the bottom of the corresponding lifting assembly is provided inside the pressing assembly, and the transmission assembly is rotatably connected to the second partition and threadedly connected to the corresponding lifting assembly.

[0008] The beneficial effects of the utility model are:

[0009] When it is necessary to take out a certain nucleic acid extraction test tube separately, the nucleic acid detection and extraction plate is provided with pressing components in the same row as the pressing components. Since the pressing components are threadedly connected to the transmission components, the downward force causes the threads to rotate, thereby causing the transmission components to rotate. Furthermore, since the transmission components are threadedly connected to the lifting components, the force generated by the rotation of the threads drives the lifting components to move upward, so that the nucleic acid extraction test tubes in the same row as the pressing components are all raised to a certain height, so that there is enough space to grab a certain nucleic acid extraction test tube separately, and it has the advantage of being easy to take out a certain nucleic acid extraction test tube separately from the nucleic acid detection and extraction plate full of nucleic acid extraction test tubes.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the lifting assembly includes a lifting plate, a rubber socket block and a socket hole. The opposite sides of the mutually adaptable slide grooves are slidably connected to the same lifting plate. The top of the lifting plate is fixedly connected to rubber socket blocks that are symmetrically distributed on the left and right. The top of the rubber socket blocks is provided with socket holes that are distributed at equal distances laterally and are adapted to the nucleic acid extraction test tubes.

[0012] The beneficial effect of adopting the above further scheme is that when the lifting plate rises upward, it will drive the nucleic acid extraction test tube in the socket hole on the rubber socket block to rise, so that there is enough space to grab a nucleic acid extraction test tube individually, and the socket hole opened on the top of the rubber socket block can facilitate the fixation of the nucleic acid extraction test tube inserted into the device, preventing the nucleic acid extraction test tube from slipping out due to up and down shaking during the transportation of the device.

[0013] Furthermore, the pressing assembly includes an internally threaded pressing sleeve and a return spring, the top of the first partition is slidably connected to an internally threaded pressing sleeve that is equidistantly distributed longitudinally and extends to the bottom thereof, the bottom edge of the internally threaded pressing sleeve is fixedly connected to a return spring located outside thereof, and the top of the return spring is fixedly connected to the bottom of the first partition;

[0014] Furthermore, the transmission assembly includes a first threaded rod, a connecting shaft and a second threaded rod. The interior of the internally threaded pressing sleeve is threadedly connected to the first threaded rod extending below it. The bottom of the first threaded rod is fixedly connected to a connecting shaft extending to the bottom of the second partition and rotatably connected to the second partition. The bottom of the connecting shaft is fixedly connected to a second threaded rod extending to the bottom of the corresponding lifting plate and threadedly connected to the corresponding lifting plate.

[0015] The beneficial effect of adopting the above-mentioned further scheme is that when it is necessary to take out a certain nucleic acid extraction test tube separately, the internal thread pressing sleeve in the same row is pressed, and then the internal thread pressing sleeve slides downward in the first partition. During this process, the reset spring undergoes elastic deformation. Since the internal thread pressing sleeve is threadedly connected to the first threaded rod, the downward force causes the first threaded rod to rotate, and then the second threaded rod is driven to rotate through the connecting shaft. Since the second threaded rod is threadedly connected to the lifting plate, the force generated by the rotation of the second threaded rod drives the corresponding lifting plate to rise upward.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the embodiment, Figure 1-5 A nucleic acid detection and extraction plate is given. The utility model includes a rectangular shell 1 and a nucleic acid extraction test tube 2, characterized in that: a grid through-hole plate 3 which is symmetrically distributed on the left and right and flush with the top of the rectangular shell 1 is fixedly connected inside the rectangular shell 1, the grid through-hole plate 3 is adapted to the nucleic acid extraction test tube 2, a first partition plate 4 which is flush with the top of the rectangular shell 1 is fixedly connected to the opposite side of the grid through-hole plate 3, a second partition plate 5 located below the first partition plate 4 is fixedly connected to the opposite side of the grid through-hole plate 3, the left and right walls of the inner cavity of the rectangular shell 1 are fixedly connected with slide grooves 6 which are equidistantly distributed in the longitudinal direction and adapted to each other, the opposite sides of the slide grooves 6 which adapt to each other are provided with the same lifting component 7 which is slidably connected thereto and adapted to the nucleic acid extraction test tube 2, the top of the first partition plate 4 is provided with a pressing component 8 which is equidistantly distributed in the longitudinal direction and extends to the bottom thereof, the interior of the pressing component 8 is provided with a transmission component 9 which is threadedly connected thereto and extends to the bottom of the corresponding lifting component 7, the transmission component 9 is rotatably connected to the second partition plate 5 and is threadedly connected to the corresponding lifting component 7;

[0024] The lifting assembly 7 includes a lifting plate 701, a rubber socket block 702 and a socket hole 703. The opposite sides of the mutually adapted slide grooves 6 are slidably connected with the same lifting plate 701. The top of the lifting plate 701 is fixedly connected with a rubber socket block 702 that is symmetrically distributed on the left and right. The top of the rubber socket block 702 is provided with a socket hole 703 that is distributed at equal distances in the transverse direction and adapted to the nucleic acid extraction test tube 2.

[0025] When the lifting plate 701 rises upward, it drives the nucleic acid extraction test tube 2 in the socket hole 703 on the rubber socket block 702 to rise, so that there is enough space to grab a nucleic acid extraction test tube 2 separately. The socket hole 703 opened on the top of the rubber socket block 702 can be used to fix the nucleic acid extraction test tube 2 inserted into the device to prevent the nucleic acid extraction test tube 2 from slipping out due to shaking up and down during the transportation of the device;

[0026] The pressing assembly 8 includes an internal thread pressing sleeve 801 and a return spring 802. The top of the first partition plate 4 is slidably connected with an internal thread pressing sleeve 801 that is distributed at equal distances in the longitudinal direction and extends to the bottom thereof. The bottom edge of the internal thread pressing sleeve 801 is fixedly connected with a return spring 802 located on the outside thereof. The top of the return spring 802 is fixedly connected to the bottom of the first partition plate 4.

[0027] The transmission assembly 9 includes a first threaded rod 901, a connecting shaft 902 and a second threaded rod 903. The interior of the internal thread pressing sleeve 801 is threadedly connected with the first threaded rod 901 extending below it. The bottom of the first threaded rod 901 is fixedly connected with a connecting shaft 902 extending to the bottom of the second partition 5 and rotatably connected to the second partition 5. The bottom of the connecting shaft 902 is fixedly connected with a second threaded rod 903 extending to the bottom of the corresponding lifting plate 701 and threadedly connected to the corresponding lifting plate 701.

[0028] When it is necessary to take out a certain nucleic acid extraction test tube 2 separately, press the internal thread pressing sleeve 801 in the same row, and then the internal thread pressing sleeve 801 slides downward in the first partition 4. During this process, the reset spring 802 undergoes elastic deformation. Since the internal thread pressing sleeve 801 is threadedly connected to the first threaded rod 901, the downward force causes the first threaded rod 901 to rotate, and then drives the second threaded rod 903 to rotate through the connecting shaft 902. Since the second threaded rod 903 is threadedly connected to the lifting plate 701, the force generated by the rotation of the second threaded rod 903 drives the corresponding lifting plate 701 to rise upward.

[0029] Working principle:

[0030] Step 1: When a nucleic acid extraction test tube 2 needs to be taken out separately, the internal thread pressing sleeve 801 in the same row is pressed, and then the internal thread pressing sleeve 801 slides downward in the first partition 4. During this process, the return spring 802 is elastically deformed. Since the internal thread pressing sleeve 801 is threadedly connected with the first threaded rod 901, the downward force causes the first threaded rod 901 to rotate, and then drives the second threaded rod 903 to rotate through the connecting shaft 902;

[0031] Step 2: Since the second threaded rod 903 is threadedly connected to the lifting plate 701, the force generated by the rotation of the second threaded rod 903 drives the corresponding lifting plate 701 to rise upward;

[0032] Step 3: When the corresponding lifting plate 701 rises upward, it drives the nucleic acid extraction test tube 2 in the socket hole 703 on the rubber socket block 702 to rise, so that there is enough space to grab a nucleic acid extraction test tube 2 separately. The socket hole 703 opened on the top of the rubber socket block 702 can facilitate the fixation of the nucleic acid extraction test tube 2 inserted into the device to prevent the nucleic acid extraction test tube 2 from slipping out due to up and down shaking during the transportation of the device.
