Description

Technical Field

[0001] The utility model belongs to the technical field of potential detectors, and in particular relates to a portable redox potential detector. Background Art

[0002] A portable redox potential meter is an instrument used for in-situ testing of media such as soil and water to measure their redox potential, pH, temperature, and other data. Widely used in research laboratories, industrial process control, and environmental monitoring, this instrument helps researchers understand and control redox reactions and assess information such as solution concentrations and environmental pollution levels. While existing redox potential meters generally meet user needs, the following challenges remain.

[0003] When using the oxidation-reduction potential detector, the operator first installs the detection head on the oxidation-reduction potential detector, and then inserts the detection head into the test medium. However, when the operator no longer uses it, the operator removes the detection head from the oxidation-reduction potential detector. The operator may place the detection head and the oxidation-reduction potential detector separately in a storage box for storage. However, since the operator needs to carry a large number of detection heads, the operator may need to carry the box to carry the oxidation-reduction potential detector and the detection head. Moreover, when the operator replaces the detection head, the operator may need to take the detection head out of the box, which may cause the operator to be inconvenient when replacing the detection head or carrying the detection head. For this reason, we propose a portable oxidation-reduction potential detector. Utility Model Content

The connecting plate 17 is elastically connected to the mounting groove 2, and the two side ends of the mounting groove 2 are symmetrically hot-melted with a slide groove 15, and the inner walls of the slide groove 15 are respectively provided with a first spring 11 and a slider 12, and the two side ends of the first spring 11 are respectively abutted between the surface of the slider 12 and the inner wall of the slide groove 15, and the surface of the slider 12 is hot-melted with a connecting plate 17. When the operator replaces the detection head, the operator first pulls the limit plug 8, and the limit plug 8 drives the connecting plate 17 to move, and the connecting plate 17 drives the slider 12 to slide in the slide groove 15, and when the slider 12 slides in the slide groove 15, the slider 12 squeezes the first spring 11, causing the first spring 11 to elastically After the first spring 11 is elastically deformed, the first spring 11 avoids the slider 12, and the slider 12 slides in the slide groove 15, causing the connecting plate 17 to move on the surface of the slide groove 15, and the limit plug 8 is moved out from the end of the installation groove 2 and the receiving groove 18, and the limit plug 8 drives the traction block 7 to move out from the notch opened at the end of the receiving groove 18, so that the limit plug 8 and the traction block 7 are no longer fixed to the receiving groove 18. The operator pulls the protective plate 4, and the circular through hole opened at the end of the protective plate 4 rotates on the surface of the cylindrical rotating shaft 3, so that the protective plate 4 drives the receiving groove 18 to rotate out of the installation groove 2, and then the operator moves the detection head It is inserted into the receiving groove 18, and the detection head is supported by the first support frame 5. Then the operator rotates the protective plate 4 again, and the protective plate 4 drives the detection head to be inserted into the installation groove 2 through the receiving groove 18. Then the operator releases the limit plug 8. The limit plug 8 no longer pulls the slider 12 through the connecting plate 17. After the slider 12 no longer squeezes the first spring 11, the elastic deformation of the first spring 11 is restored, and the first spring 11 pushes the slider 12 to move.

[0029] The first spring groove 22 is symmetrically provided on both sides of the rotating block 21, and the first spring groove 22 is provided with a third spring 20 and a positioning button 23. The ends of the third spring 20 are respectively abutted between the inner wall of the first spring groove 22 and the surface of the positioning button 23. The ends of the positioning button 23 are sleeved with abutting grooves 13 provided on the inner wall of the rotating groove 19. When the operator needs to push the mounting groove 2 and the mounting groove 2 is removed from the battery cover provided on the back of the detector body 1, the operator first pushes the mounting groove 2, and the mounting groove 2 drives the rotating block 21 to slide in the rotating groove 19. When the rotating block 21 slides in the rotating groove 19, the rotating block 21 drives the first spring groove 22 to move, and the first spring groove 22 drives the positioning button 23 to move, so that the end of the positioning button 23 abuts against the inner wall of the abutting groove 13, and the end of the positioning button 23 abuts against When the third spring 20 is elastically deformed, the third spring 20 avoids the positioning button 23, so that the positioning button 23 enters the first spring groove 22, and the rotating block 21 rotates in the rotating groove 19, so that the installation slot 2 is rotated on the back of the detector body 1, and the installation slot 2 is moved out of the battery cover set on the back of the detector body 1. When the rotating block 21 drives the positioning button 23 to move to the front end of the supporting groove 13 through the first spring groove 22, the elastic deformation of the third spring 20 is restored, and the third spring 20 pushes the positioning button 23 to move, so that the positioning button 23 is inserted into the supporting groove 13, fixing the rotating block 21 in the rotating groove 19, making it convenient for the operator to fix the position of the installation slot 2.

[0030] In other embodiments, the end of the positioning button 23 is configured as a semicircular block, and the groove 13 is configured as a semicircular groove that matches the end of the positioning button 23. The semicircular block set at the end of the positioning button 23 matches the semicircular groove set at the groove 13, so that the positioning button 23 can be inserted into the groove 13, and the surface of the positioning button 23 fits with the inner wall of the groove 13.

The second spring 14 undergoes elastic deformation. After the second spring 14 undergoes elastic deformation, the second spring 14 avoids the push block 24, allowing the positioning rod 27 to enter the second spring groove 26, and the positioning rod 27 moves out of the through hole opened on the surface of the second bracket 10, so that the first bracket 9 and the second bracket 10 are separated, which facilitates the installation slot 2 to drive the second bracket 10 to slide on the surface of the first bracket 9, and when the second bracket 10 moves to the first bracket 9 again, the second spring 14 elastic deformation is restored, the second spring 14 pushes the push block 24 to move, and the push block 24 drives the positioning rod 27 to move, so that the positioning rod 27 is inserted into the through hole opened in the middle of the second bracket 10, fixing the second bracket 10 and the first bracket 9 to each other, making it convenient for the operator to fix the first bracket 9 and the second bracket 10, so that the first bracket 9 and the second bracket 10 support both sides of the installation slot 2 and the detector body 1, increasing the stability of the installation slot 2.

[0032] In other embodiments, the second bracket 10 is configured as an arc block that matches the first bracket 9. The arc block set on the second bracket 10 matches the first bracket 9, so that when the second bracket 10 slides on the surface of the first bracket 9, the second bracket 10 and the first bracket 9 fit together, thereby increasing the stability of the second bracket 10 sliding on the surface of the first bracket 9.

[0033] In other embodiments, the middle of the first spring 11 and the slider 12 are both penetrated by a slider 16 that is hot-melt bonded to the inner wall of the slide groove 15, and the slider 16 is set to be cylindrical, and the middle of the slider 12 is provided with a circular through hole that matches the slider 16. The cylindrical shape of the slider 16 matches the circular through hole opened in the middle of the slider 12, so that the circular through hole opened in the middle of the slider 12 can slide on the surface of the slider 16 set to be cylindrical, so that the slider 16 pulls the moving direction of the slider 12, thereby increasing the stability of the slider 12 sliding in the slide groove 15.
