Description

Technical Field

[0001] This utility model relates to the field of detection technology, specifically to a detection device for nicotinamide adenine dinucleotide. Background Technology

[0002] Nicotinamide adenine dinucleotide exists in two forms in mammals: oxidized and reduced (NADH). Nicotinamide adenine dinucleotide participates in various physiological activities such as cellular metabolism, energy synthesis, and cellular DNA repair, and plays an important role in the body's immune function.

[0003] For example, CN213482081 U discloses a detection device for nicotinamide adenine dinucleotide. A second electric push rod inside the second housing can push a second and third slider inside the second slide rail, causing a motor and protective shell located at the bottom of a fixed rod to move accordingly. A grinding groove in the middle of the grinding disc can cooperate with a grinding head located at the bottom of a rotating rod, allowing the grinding head to grind the drug inside the grinding groove. A first electric push rod inside the first housing can push a first slider to move, causing the grinding disc located at the top of a fixed column to move accordingly. This eliminates manual operation, avoiding contamination and saving manpower.

[0004] However, the existing nicotinamide adenine dinucleotide detection device requires manual crushing to prepare the sample for testing, and then the sample is analyzed by a drug component analyzer. During the grinding process, the material tends to stick to the grinding tank and grinding disc, so it is necessary to clean the material stuck to the grinding tank and grinding disc.

[0005] Therefore, we need a detection device for nicotinamide adenine dinucleotide (NADNU) that solves the grinding problem of existing NADNU detection devices and also enables the cleaning of materials in the grinding tank during the NADNU grinding process. Utility Model Content

[0006] The purpose of this invention is to provide a detection device for nicotinamide adenine dinucleotide (NADNU) to solve the grinding problem of existing NADNU detection devices mentioned in the background art, and also to achieve material cleaning in the grinding tank during the NADNU grinding process.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a detection device for nicotinamide adenine dinucleotide, wherein a grinding chamber has a receiving cavity and a grinding groove inside, a hopper is provided on the top surface of the grinding chamber, a drive motor is fixedly connected to the top surface of the grinding chamber, the device includes a drive motor, a drive rod is fixedly connected to the end of the power output shaft of the drive motor, the surface of the drive rod is rotatably connected to the surface of the grinding groove, the surface of the drive rod is rotatably connected to the interior of a stable support frame, the end of the support rod of the stable support frame is fixedly connected to the surface of the grinding groove, the bottom end of the drive rod is fixedly connected to the top surface of the grinding disc, the surface of the grinding disc is rotatably connected to the surface of the grinding groove, and a cleaning scraper is provided on the surface of the grinding disc.

[0008] Preferably, the storage cavity and the grinding tank are connected in communication, and a material storage box is movably connected to the surface of the storage cavity.

[0009] Preferably, the grinding disc has a limiting groove inside, the surface of the limiting groove is fixedly connected to the end of the fixing pin, the surface of the fixing pin is rotatably connected to the inside of the cleaning scraper, the bottom end of the cleaning scraper contacts the surface of the grinding groove, and there are two cleaning scrapers, which are symmetrically arranged along the center point of the grinding groove.

[0010] Preferably, the surface of the grinding groove is provided with an integrally formed convex ball, the outer surface of the convex ball abuts against the outer surface of the guide roller, the surface of the stabilizing rod is rotatably connected to the inside of the guide roller, the end of the stabilizing rod is fixedly connected to the inner surface of the two side plates of the mounting frame, the surface of the mounting frame is fixedly connected to a shrink rod, the surface of the shrink rod is movably connected to the inside of the cavity tube, a return spring is provided inside the cavity tube, and the end of the cavity tube is fixedly connected to the surface of the grinding groove.

[0011] Preferably, the convex ball has an arc-shaped cross-section, and there are several convex balls, which are evenly distributed on the edge surface of the grinding disc.

[0012] Preferably, the retractable rod has a "T" shaped cross-section, and an integrally formed limiting disc is provided at the end of the retractable rod. The radius of the end limiting disc of the retractable rod is equal to the inner radius of the cavity tube.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the drive motor is started, the drive rod drives the grinding disc to rotate on the surface of the grinding tank, thereby automatically grinding the material inside the grinding tank through the grinding disc. The ground material is convenient for workers to inspect and enters the inside of the storage cavity, thus avoiding manual operation. When the grinding disc grinds the material on the surface of the grinding tank, the cleaning scraper cleans and removes the material adhering to the surface of the grinding tank. The surface of the fixing pin is rotatably connected to the inside of the cleaning scraper, so that the cleaning scraper can adjust its posture on the surface of the grinding tank along with the rotation of the grinding disc. Therefore, the automatic rotation of the cleaning scraper driven by the grinding disc automatically cleans and removes the ground material adhering to the surface of the grinding tank. As the grinding disc rotates automatically on the surface of the grinding tank, the grinding disc impacts the surface of the guide roller, causing the material adhering to the grinding disc surface to fall off during the grinding process. This further solves the grinding problem of the existing nicotinamide adenine dinucleotide detection device and also realizes the cleaning of the material in the grinding tank during the grinding process of nicotinamide adenine dinucleotide.

[0023] Please see Figures 1-6 This utility model provides a technical solution: a detection device for nicotinamide adenine dinucleotide, wherein the grinding box 1 has a storage cavity 4 and a grinding groove 6 inside, a hopper 2 is provided on the top surface of the grinding box 1, a drive motor 3 is fixedly connected to the top surface of the grinding box 1, including the drive motor 3, a drive rod 7 is fixedly connected to the end of the power output shaft of the drive motor 3, the surface of the drive rod 7 is rotatably connected to the surface of the grinding groove 6, the surface of the drive rod 7 is rotatably connected to the interior of the stable support frame 8, the end of the support rod of the stable support frame 8 is fixedly connected to the surface of the grinding groove 6, the bottom end of the drive rod 7 is fixedly connected to the top surface of the grinding disc 9, the surface of the grinding disc 9 is rotatably connected to the surface of the grinding groove 6, and a cleaning scraper 12 is provided on the surface of the grinding disc 9;

[0024] By rotating the surface of the drive rod 7 to connect to the inner ring surface of the stable support frame 8, when material is added into the grinding tank 6 through the hopper 2, the drive motor 3 is started, causing the drive rod 7 to drive the grinding disc 9 to rotate on the surface of the grinding tank 6. Thus, the grinding disc 9 automatically grinds the material inside the grinding tank 6. The ground material is convenient for staff to inspect. The ground material enters the storage cavity 4, thus avoiding manual operation. At the same time, a cleaning scraper 12 is provided on the surface of the grinding disc 9. When the grinding disc 9 grinds the material on the surface of the grinding tank 6, the cleaning scraper 12 cleans and scrapes off the material adhering to the surface of the grinding tank 6.

[0025] Example 2

[0026] See attached document Figures 1 to 6 Based on Embodiment 1, in order to automatically clean and scrape off the ground material adhering to the surface of the grinding tank 6, a limiting slot 11 is provided inside the grinding disc 9. The surface of the limiting slot 11 is fixedly connected to the end of the fixing pin 13, and the surface of the fixing pin 13 is rotatably connected to the inside of the cleaning scraper 12. The bottom end of the cleaning scraper 12 contacts the surface of the grinding tank 6. There are two cleaning scrapers 12, and the two cleaning scrapers 12 are symmetrically arranged along the center point of the grinding tank 6.

[0027] By opening a limiting slot 11 inside the grinding disc 9, the surface of the fixing pin 13 is rotatably connected to the inside of the cleaning scraper 12. Thus, the cleaning scraper 12 can adjust its posture on the surface of the grinding tank 6 along with the rotation of the grinding disc 9. Therefore, the grinding disc 9 drives the cleaning scraper 12 to automatically clean and scrape off the ground material adhering to the surface of the grinding tank 6.

[0028] Example 3

[0029] See attached document Figures 1 to 6 Based on Embodiment 2, in order to shake off the material adhering to the surface of the grinding disc 9 during the grinding process, the surface of the grinding tank 6 is provided with an integrally formed convex ball 10. The outer surface of the convex ball 10 abuts against the outer surface of the guide roller 19. The surface of the stabilizing rod 18 is rotatably connected inside the guide roller 19. The end of the stabilizing rod 18 is fixedly connected to the inner surface of the two side plates of the mounting frame 16. The surface of the mounting frame 16 is fixedly connected with a shrinking rod 15. The surface of the shrinking rod 15 is movably connected to the inside of the cavity tube 14. A return spring 17 is provided inside the cavity tube 14. The end of the cavity tube 14 is fixedly connected to the surface of the grinding tank 6.

[0030] By setting an integrally formed convex ball 10 on the edge surface of the grinding disc 9, the grinding disc 9 automatically rotates on the surface of the grinding groove 6, thus impacting the surface of the guide roller 19, causing the material adhering to the surface of the grinding disc 9 during the grinding process to be shaken off. At the same time, the surface of the internal rotating connection of the guide roller 19 to the stabilizing rod 18 is connected, so that the guide roller 19 can rotate inside the mounting frame 16 to reduce friction. When the convex ball 10 impacts the surface of the guide roller 19, it pushes the shrinking rod 15 to shrink to the surface of the cavity tube 14. Therefore, the elastic force of the return spring 17 causes the shrinking rod 15 to push the guide roller 19 to reciprocate to impact the surface of the convex ball 10.

[0031] In actual use, by rotating the surface of the drive rod 7 to connect to the inner ring surface of the stable support frame 8, when material is added into the grinding tank 6 through the hopper 2, the drive motor 3 is started, causing the drive rod 7 to drive the grinding disc 9 to rotate on the surface of the grinding tank 6. This allows the grinding disc 9 to automatically grind the material inside the grinding tank 6. The ground material is then easily inspected by staff and enters the storage cavity 4, thus avoiding manual operation. Simultaneously, a cleaning scraper 12 is provided on the surface of the grinding disc 9. When the grinding disc 9 grinds the material on the surface of the grinding tank 6, the cleaning scraper 12 cleans and removes the material adhering to the surface of the grinding tank 6. A limiting slot 11 is provided inside the grinding disc 9, allowing the surface of the fixing pin 13 to be rotatably connected to the inside of the cleaning scraper 12, thus allowing the cleaning scraper 12 to move freely during grinding. The grinding disc 9 rotates and adjusts its posture on the surface of the grinding tank 6. Therefore, the grinding disc 9 drives the automatic rotation of the cleaning scraper 12 to automatically clean and scrape off the ground material adhering to the surface of the grinding tank 6. By setting an integrally formed convex ball 10 on the edge surface of the grinding disc 9, the grinding disc 9 rotates automatically on the surface of the grinding tank 6. Therefore, the grinding disc 9 impacts the surface of the guide roller 19, thereby shaking off the material adhering to the surface of the grinding disc 9 during the grinding process. At the same time, the surface of the internal rotating connection of the guide roller 19 to the stabilizing rod 18 is connected, so that the guide roller 19 can rotate inside the mounting frame 16 to reduce friction. When the convex ball 10 impacts the surface of the guide roller 19, it pushes the shrinking rod 15 to shrink to the surface of the cavity tube 14. Therefore, the elastic force of the return spring 17 causes the shrinking rod 15 to push the guide roller 19 to reciprocate to impact the surface of the convex ball 10.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
