Description

Technical Field

[0001] The utility model relates to the technical field of nucleic acid and protein detection, in particular to a novel nucleic acid and protein detector. Background Art

[0002] The nucleic acid and protein detector has a single optical path structure and is composed of three parts: an ultraviolet detector, a power supply, and a recorder. The ultraviolet detector is connected to the power supply and belongs to a monomer structure. Among them, the power supply is responsible for providing energy, the recorder is responsible for outputting detection data in paper form, and the ultraviolet detector is the core component of the nucleic acid and protein detector. It mainly consists of a group of light sources, four interference filter plates, a condenser lens, a sample cell, a photomultiplier tube, an amplifier board, and a logarithmic board, etc. The main principle is roughly that the light emitted from the light source passes through a slit, and the color filter focuses on the sample cell. This monochromatic light passes through the sample cell and reaches the photocathode surface of the photomultiplier tube, converting the change in the light transmission intensity caused by different sample concentrations into a change in photocurrent. This photocurrent is amplified by an amplifier and input into a logarithmic converter, thereby achieving detection.

[0003] However, in the actual use scenario of the nucleic acid and protein detector, the photomultiplier tube in the ultraviolet detector often causes fluctuations in the photocurrent on the photocathode surface due to the complex electromagnetic environment inside the detector. For example, when the human-computer interaction interface for nucleic acid and protein detection is too close to the photomultiplier tube, or when there are fluctuations in the current and voltage in the circuit, etc., it may cause unstable conversion data of the photomultiplier tube.

[0004] Based on this, a novel nucleic acid and protein detector that can solve the above problems is proposed. Content of the Utility Model

[0005] To solve the technical problem of poor stability caused by electromagnetic interference in the nucleic acid and protein detector, the utility model provides a novel nucleic acid and protein detector.

[0006] The utility model is realized by adopting the following technical solutions: A novel nucleic acid and protein detector includes a detection table. An accommodation groove is opened on the upper side of the detection table. An installation table is arranged inside the accommodation groove. A sample cell is arranged on the upper side of the installation table. Above the sample cell, a nucleic acid and protein detection unit fixedly connected to the upper side of the installation table is arranged. The nucleic acid and protein detection unit is composed of an ultraviolet detector, a power supply, and a recorder. On one side of the accommodation groove, an installation table separation mechanism for lifting the installation table from the accommodation groove is arranged. On one side of the detection table, a touch digital display mechanism for facilitating human-computer interaction is arranged. A wire mechanism with a telescopic length is arranged between the installation table and the detection table.

[0007] As a further improvement of the above solution, the installation table separation mechanism includes a first fixed plate and a second fixed plate fixedly connected inside the detection table. At one end of the first fixed plate and the second fixed plate close to the receiving groove, clamping grooves are respectively formed. A slider is slidably connected to the inner sides of the two clamping grooves. A motor driving mechanism for moving the slider up and down along the clamping grooves is arranged on the lower side of the slider. A connecting plate connecting mechanism for keeping the installation table and the slider in linkage is arranged on the slider.

[0008] As a further improvement of the above solution, the motor driving mechanism includes a servo motor fixedly connected to the bottom side inside the detection table. The output end of the servo motor is fixedly connected with a screw rod. The upper end of the screw rod is rotatably connected to the upper side of the detection table. The screw rod is threadedly sleeved with the slider.

[0009] As a further improvement of the above solution, the connecting plate connecting mechanism includes a running horse groove formed on the slider. A connecting plate is slidably connected to the inner side of the running horse groove. One end of the connecting plate is fixedly connected to one side of the installation table. A clamping rod mechanism for pushing the connecting plate to slide back and forth along the inner side of the running horse groove is arranged at the other end of the connecting plate.

[0010] As a further improvement of the above solution, the clamping rod mechanism includes limiting sliding grooves respectively formed on the first fixed plate and the second fixed plate. The two limiting sliding grooves are both located on the side far from the slider. A clamping rod is slidably connected to the inner sides of the two limiting sliding grooves. The clamping rod is fixedly connected to the other end of the connecting plate.

[0011] As a further improvement of the above solution, when the slider is at the initial position at the lowest end of the clamping groove, the clamping rod is at the lowest point of the two limiting sliding grooves, and the installation table is at the initial position inside the receiving groove;

[0012] When the slider leaves the initial position of the clamping groove and moves upward to the uppermost end of the clamping groove, the clamping rod leaves the lowest point of the two limiting sliding grooves and moves obliquely upward along the inner side of the limiting sliding groove to the highest point of the limiting sliding groove, and the installation table rises from inside the receiving groove and is in a state of being separated from the detection table body.

[0013] As a further improvement of the above solution, the touch digital display mechanism includes an LED touch display unit installed on one side of the detection table.

[0014] As a further improvement of the above solution, the wire mechanism includes an elastic wire arranged between the LED touch display unit and the installation table. One end of the elastic wire is electrically connected to the LED touch display unit, and the other end of the elastic wire is electrically connected to the inside of the installation table.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. By setting up the mounting table separation mechanism, the nucleic acid and protein detection unit carrying the photomultiplier tube is actively separated from the circuit electromagnetic environment inside the detection table during nucleic acid and protein detection, thereby reducing the influence of the external magnetic field on the formation of photocurrent by the photomultiplier tube, and making the detection data output of the nucleic acid and protein detection unit more stable, more scientific and accurate.

[0017] 2. The mounting table and the nucleic acid and protein detection unit of the present utility model rise when the detection table performs nucleic acid and protein detection work, and retract after the detection work is completed, making the nucleic acid and protein detector of the present utility model have the functional advantages of being easy to store and easy to carry and transfer.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, in combination with the drawings and the specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, any combination can be formed between the following described embodiments or technical features.

[0026] Embodiment:

[0027] Please combine with Figures 1-5, a novel nucleic acid and protein detector according to this embodiment includes a detection table 1. A receiving groove 3 is formed on the upper side of the detection table 1. An installation table 5 is arranged inside the receiving groove 3. A sample pool 6 is arranged on the upper side of the installation table 5. Above the sample pool 6, there is a nucleic acid and protein detection unit 4 fixedly connected to the upper side of the installation table 5. The nucleic acid and protein detection unit 4 consists of an ultraviolet detector, a power supply, and a recorder part. The ultraviolet detector includes core components such as a photomultiplier tube. One side of the receiving groove 3 is provided with an installation table separation mechanism for raising the installation table 5 from the receiving groove 3. One side of the detection table 1 is provided with a touch digital display mechanism for facilitating human-machine interaction. A wire mechanism with a telescopic length is arranged between the installation table 5 and the detection table 1.

[0028] Please refer to Figure 5 As shown, the installation table separation mechanism includes a first fixing plate 14 and a second fixing plate 15 fixedly connected inside the detection table 1. At one end of the first fixing plate 14 and the second fixing plate 15 close to the receiving groove 3, a clamping groove 17 is formed. A slider 10 is slidably connected to the inner sides of the two clamping grooves 17. Clamping plate structures are arranged on both sides of the slider 10. A motor driving mechanism for moving the slider 10 up and down reciprocally along the clamping groove 17 is arranged on the lower side of the slider 10. A connecting plate connecting mechanism for keeping the installation table 5 and the slider 10 in linkage is arranged on the slider 10. Through the above technical solution, the slider 10 can move up and down smoothly along the clamping groove 17.

[0029] Please refer to Figure 4 As shown, the motor driving mechanism includes a servo motor 9 fixedly connected to the bottom side inside the detection table 1. The output end of the servo motor 9 is fixedly connected with a screw rod 11. The upper end of the screw rod 11 is rotatably connected to the upper side of the detection table 1. The screw rod 11 is threadedly sleeved with the slider 10.

[0030] By controlling the forward or reverse rotation of the servo motor 9, the slider 10 is raised or lowered along the clamping groove 17, thereby indirectly controlling the effect of raising or lowering and receiving the installation table 5 from the receiving groove 3.

[0031] Please refer to Figure 5 As shown, the connecting plate connecting mechanism includes a running horse groove 16 formed on the slider 10. A connecting plate 8 is slidably connected to the inner side of the running horse groove 16. One end of the connecting plate 8 is fixedly connected to one side of the installation table 5. A clamping rod mechanism for pushing the connecting plate 8 to slide back and forth reciprocally along the inner side of the running horse groove 16 is arranged at the other end of the connecting plate 8.

[0032] Please refer to Figure 5 As shown, the clamping rod mechanism includes limiting sliding grooves 12 formed on both the first fixing plate 14 and the second fixing plate 15. The two limiting sliding grooves 12 are both located on the side far from the slider 10. A clamping rod 13 is slidably connected to the inner sides of the two limiting sliding grooves 12. The clamping rod 13 is fixedly connected to the other end of the connecting plate 8.

[0033] It should be noted in particular that the track distance parameter of the limit chute 12, the track arc structure, and the distance and form of the mounting table 5 separated from the detection table 1 are directly related. The longer front-back distance of the limit chute 12 can increase the separation distance between the mounting table 5 and the detection table 1, thereby achieving a better effect of avoiding electromagnetic interference. In this embodiment, the track structure of the limit chute 12 is a straight line slanting upward. In other embodiments of the present utility model, in the starting stage of the track of the limit chute 12, it inclines upward at a small angle for a certain distance and then inclines upward at a large angle. In this way, when the mounting table 5 and the detection table 1 are just separated, the rising speed in the Y-axis direction can be reduced, creating a better space for separation.

[0034] When the slider 10 is at the lowest initial position of the card slot 17, the clamping rod 13 is at the lowest points of the two limit chutes 12, and the mounting table 5 is at the initial position inside the receiving groove 3;

[0035] When the slider 10 leaves the initial position of the card slot 17 and moves upward to the uppermost end of the card slot 17, the clamping rod 13 leaves the lowest points of the two limit chutes 12 and moves obliquely upward along the inner side of the limit chute 12 to the highest point of the limit chute 12, and the mounting table 5 rises from inside the receiving groove 3 and is in a state of being separated from the main body of the detection table 1.

[0036] Please refer to Figure 1 As shown, the touch digital display mechanism includes an LED touch display unit 2 installed on one side of the detection table 1. The LED touch display unit 2 is a 5-inch color touch screen and requires a power supply with DC 5V and 2A current and a power of 10W.

[0037] Please refer to Figure 1 As shown, the wire mechanism includes an elastic wire 7 arranged between the LED touch display unit 2 and the mounting table 5. One end of the elastic wire 7 is electrically connected to the LED touch display unit 2, and the other end of the elastic wire 7 is electrically connected to the inside of the mounting table 5.

[0038] The implementation principle of a new type of nucleic acid and protein detector in the embodiment of this application is as follows: When nucleic acid and protein detection is required, the servo motor 9 is started. By rotating the screw rod 11, the slider 10 is driven to move upward along the card slot 17. At this time, since one end of the connecting plate 8 is fixedly connected to the clamping rod 13, and the two ends of the clamping rod 13 are limited and held by the limit chutes 12 on both sides, the clamping rod 13 moves obliquely upward along the limit chute 12. The connecting plate 8 is pushed by the clamping rod 13 at one end, pushing the mounting table 5 out of the receiving groove 3 and gradually rising, achieving the effect of separating from the detection table 1 and effectively avoiding electromagnetic interference.

[0039] The above embodiments are only the preferred embodiments of the present utility model, and the scope of protection of the present utility model cannot be limited thereby. Any non-substantive changes and substitutions made by those skilled in the art based on the present utility model fall within the scope of protection required by the present utility model.
