DETAILED DESCRIPTION
[0027] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0028] Example 1
[0029] A device for rapid detection of mercury content in food, see Figure 1-Figure 5As shown, it includes a detector housing 1, a first rotating shaft 2, a guide frame 3, a support plate 4, a clamping ring 5, a bolt 6, a test tube 7, a detection component and a first protrusion 12. The first rotating shaft 2 is rotatably arranged on the left and right sides of the detector housing 1. Two guide frames 3 are fixedly connected to the first rotating shaft 2 by welding. The two guide frames 3 are slidably arranged on the support plates 4. A hollow pull ring is arranged on the side of the support plate 4 away from the first rotating shaft 2 to facilitate pushing and pulling the support plate 4 for sliding. Two through holes of the same size are provided on the support plate 4 for placing the test tube 7. The test tube 7 is sleeved with a clamping ring 5, and a threaded design is arranged on the clamping ring 5. Bolts 6 are arranged, and the clamp ring 5 is fixed on the test tube 7 by the bolts 6, and the test tube 7 is placed in the through hole of the support plate 4. The clamp ring 5 limits the test tube 7 to prevent the test tube 7 from slipping. The right end of the first rotating shaft 2 penetrates to the right side of the detector housing 1. The right end of the first rotating shaft 2 is installed with a first protrusion 12 by welding. The outer wall of the detector housing 1 is installed with a detection component. The first protrusion 12 is triggered to start the detection component by rotating the first rotating shaft 2. It also includes a push rod 8, a connecting frame 13, a liquid storage frame 14, a guide tube 15, a ball valve 16, a rotating rod 17, a sleeve 1701, a second protrusion 18 and a torsion spring 19. Push rods 8 are symmetrically installed on the left and right sides of the top of the support plate 4 by welding. When the support plate 4 slides on the guide frame 3, the push rod 8 is driven to move. A plurality of connecting frames 13 are fixedly connected to the two guide frames 3 by welding. The total number of connecting frames 13 is 8. A liquid storage frame 14 is installed on the upper part of each of the four connecting frames 13 by bolt connection. The four connecting frames 13 connected to the liquid storage frame 14 are symmetrically distributed on the left and right. The bottom of the liquid storage frame 14 is connected and connected to the left and right guide pipes 15. The guide pipes 15 are each provided with a ball valve 16. By controlling the ball valve 16, the indicating liquid in the liquid storage frame 14 is discharged from the guide pipe 15. The water flows out downward, and the sides of the two ball valves 16 away from each other are fixedly connected with a rotating rod 17 by welding. A sleeve 1701 is arranged on the outer sleeve of the rotating rod 17. The sleeve 1701 is fixedly connected to the side wall of the guide pipe 15 by welding. The end of the rotating rod 17 away from the ball valve 16 is fixedly connected with a second protrusion 18 by welding. A torsion spring 19 is fixedly connected between the second protrusion 18 and the sleeve 1701 by welding. The torsion spring 19 is wound around the rotating rod 17. The rotating rod 17 drives the ball valve 16 to rotate by rotating the second protrusion 18, and the second protrusion 18 is reversed and reset by the torsion spring 19.
[0030] See also Figure 2 and Figure 3 As shown, it also includes a clamping block 201 and a cross block 1201. The left and right sides of the first rotating shaft 2 are fixedly connected to the cross block 1201 by welding, and the left and right inner walls of the detector housing 1 are fixedly connected with two clamping blocks 201 by bolt connection. The clamping block 201 is used to limit the cross block 1201, thereby limiting the rotation angle of the first rotating shaft 2.
[0031] See also Figure 3 As shown, the detection component includes a spectral detection instrument 9, a circuit line 10 and a button 11. The spectral detection instrument 9 is installed on the rear part of the outer wall of the detector housing 1 by bolt connection. The spectral detection instrument 9 penetrates into the interior of the detector housing 1 to facilitate the detection of mercury content. The button 11 is installed on the right part of the outer wall of the detector housing 1 by bolt connection. The spectral detection instrument 9 and the button 11 are electrically connected through the circuit line 10. Pressing the button 11 turns on the spectral detection instrument 9.
[0032] When the mercury content of the food sample is to be tested, the first rotating shaft 2 is first rotated to turn the guide frame 3 outward. As the first rotating shaft 2 rotates, the first protrusion 12 rotates and presses the button 11. The button 11 starts the spectrum detection instrument 9 to work through the circuit line 10. At the same time, the cross block 1201 contacts the block 201 to limit the first rotating shaft 2 to prevent the first rotating shaft 2 from rotating excessively and causing the guide frame 3 to tilt. Then, the support plate 4 is slid out along the guide frame 3 to the side away from the first rotating shaft 2, and the two clamping rings 5 are respectively fixed to the upper parts of the two test tubes 7 by bolts 6, so that the two test tubes 7 are respectively placed in the two through holes of the support plate 4, and then the food sample is placed in one of the test tubes 7, and equal amounts of pure water are added to the two test tubes 7 respectively, and then the indicator is added to the two liquid storage frames 14 respectively, and the support plate 4 is pushed to slide along the guide frame 3 to align the two test tubes 7 with the two guide tubes 15. At the same time, the push rod 8 pushes the second protrusion 18 to rotate, thereby causing the rotating rod 17 and the ball valve 16 to rotate in the sleeve 1701 and the guide tube 15 respectively, so that the guide tube 15 is in a flow state, and the torsion spring 19 is deformed as the second protrusion 18 rotates. After the indicator in the liquid storage frame 14 flows into the two test tubes 7, the support plate 4 is pushed to the bottom of the other liquid storage frame 14. At this time, the two push rods 8 are separated from the two second protrusions 18 on the front side, and the second protrusion 18 is rotated and reset by the torsion spring 19, driving the rotating rod 17 and the ball valve 16 to reverse, so that the guide tube 15 is in a closed state, and at this time, the indicator in the other liquid storage frame 14 is added to the two test tubes 7 through the above operation. After the indicator is added, the support plate 4 drives the two test tubes 7 to slide along the guide frame 3 to the side of the spectrum detection instrument 9, and the spectrum detection instrument 9 is used to compare the mercury content of the blank liquid and the sample liquid in the two test tubes 7.
[0033] Example 2
[0034] Based on Example 1, see Figure 4 and Figure 6As shown, it also includes a support block 20, a first elastic member 21, a pressure block 22, a second rotating shaft 23, a spur gear 24, a pulley assembly 25, a support frame 26, a slide rail 27, a rack 28, a guide rod 29 and a second elastic member 30. The bottom of the detector housing 1 is rotatably provided with two left and right second rotating shafts 23, and the second rotating shafts 23 penetrate to the outer bottom of the detector housing 1. The second rotating shafts 23 are fixedly connected to the support blocks 20 by welding. The support blocks 20 are slidably provided with pressure blocks 22. The pressure blocks 22 slide up and down along the support blocks 20. The top of the pressure blocks 22 is a hemispherical concave groove, which is convenient for fully fitting with the bottom of the test tube 7 to support the test tube 7. A first elastic member 21 for pushing the pressure block 22 to slide upward is connected between the pressure block 22 and the support block 20. The lower part of the second rotating shaft 23 on the right side is fixedly connected with a spur gear 24 through a key. The spur gear 24 is located at the detection On the outside of the detector housing 1, two second rotating shafts 23 are connected together with a pulley assembly 25. Rotating one of the rotating shafts drives the pulley assembly 25 to transmit, so that the other rotating shaft rotates accordingly. A slide rail 27 is installed on the outer bottom of the detector housing 1 by bolt connection. A rack 28 is slidably arranged on the slide rail 27. The rack 28 is located on the front side of the slide rail 27. The rack 28 slides left and right on the slide rail 27. The rack 28 is meshed with the spur gear 24. The spur gear 24 drives the second rotating shaft 23 to rotate through the sliding of the slide rail 27. A support frame 26 is installed on the lower right part of the outer wall of the detector housing 1 by bolt connection. A guide rod 29 is fixedly connected to the side of the rack 28 close to the support frame 26 by welding. The guide rod 29 is slidably connected to the support frame 26. A second elastic member 30 is wound around the side of the guide rod 29 away from the rack 28. The second elastic member 30 is located on the right side of the support frame 26.
[0035] Before the spectrum detection instrument 9 detects the blank liquid and the sample liquid, when the two test tubes 7 are in contact with the pressing block 22, as the support plate 4 moves, the two test tubes 7 push the two pressing blocks 22 to slide downward along the support block 20. At this time, the first elastic member 21 is compressed and deformed. When the test tube 7 is directly above the pressing block 22, the pressing block 22 slides upward and resets through the first elastic member 21, and the test tube 7 is slightly lifted. Then the staff pushes the guide rod 29. At this time, the second elastic member 30 is compressed and deformed. The guide rod 29 pushes the rack 28 to slide in the slide rail 27. Under the meshing action, the rack 28 causes the spur gear 24 to rotate, thereby driving the second spur gear 24 connected to the spur gear 24. The rotating shaft 23 rotates, and the second rotating shaft 23 drives another second rotating shaft 23 to rotate through the transmission of the pulley assembly 25. The two second rotating shafts 23 drive the corresponding support blocks 20 to rotate, so that the test tubes 7 on the two pressing blocks 22 rotate. When the guide rod 29 is loosened, the guide rod 29 is reset through the second elastic member 30, so that the rack 28 slides in the opposite direction, and the spur gear 24 and the second rotating shaft 23 are reversed, so that the support block 20 and the pressing block 22 drive the test tube 7 to reverse, so that the solution in the test tube 7 and the indicator are fully mixed by the centrifugal force generated by the rotation, and then the mercury content of the sample liquid and the blank liquid is compared and detected using the spectral detection instrument 9.
[0036] See also Figure 7 As shown, it also includes a stopper 31, a limiting ring 32 and a baffle 33. The baffle 33 is rotatably arranged on the upper front side of the detector housing 1. The stopper 31 and two limiting rings 32 are installed on the top front side of the detector housing 1 by bolt connection. The two limiting rings 32 are located on the left and right sides of the stopper 31. The limiting rings 32 are slidably connected to the baffle 33. The stopper 31 limits the rotation angle of the baffle 33.
[0037] When the device needs to be used, the detector housing 1 is opened by rotating the baffle 33 upward along the limit ring 32, and then the first rotating shaft 2 drives the guide frame 3 to rotate out. When the device is not in use, the baffle 33 is rotated downward along the limit ring 32 to make the detector housing 1 in a closed state. The block 31 is used to limit the rotation angle of the baffle 33 to prevent the baffle 33 from rotating excessively and being difficult to reverse and close.
[0038] See also Figure 5 and Figure 7As shown, the left side of the top of the two liquid storage frames 14 are both rotatably provided with a baffle plate 34 for preventing dust from falling in, and a groove block is installed on the right side of the top of the baffle plate 34 by bolt connection, which is convenient for the staff to buckle and turn the baffle plate 34 over, and the rear side of the outer wall of the detector housing 1 is installed with two symmetrical mounting brackets 35 for fixing it on the wall by bolt connection. The baffle plate 34 is used to prevent dust from falling into the indicator of the liquid storage frame 14 to avoid affecting the detection data, and the mounting bracket 35 is used to install the detector housing 1 on the wall.
