Description

Technical Field

[0001] This utility model relates to the field of thickness gauge technology, and in particular to an infrared thickness gauge. Background Technology

[0002] An infrared thickness gauge is a non-contact measuring device based on infrared spectroscopy technology. It is mainly used to measure the thickness of materials. Its working principle is based on the absorption characteristics of infrared light. The thickness of the material is calculated by measuring the absorption and transmission of infrared light in the material.

[0003] Infrared thickness gauges use a probe that is perpendicular to the object being measured. However, if the object moves or the worker's hand shakes due to prolonged pressure, the probe may not be in contact with the object, affecting the measurement results. Furthermore, the probe is protected with a protective lens to prevent foreign objects from entering and causing hand damage. However, the maintenance and disassembly of traditional protective lenses is time-consuming and laborious, which can easily cause worker fatigue. Utility Model Content

[0030] This utility model provides, for example Figures 1-3 An infrared thickness gauge is shown, comprising a housing 1, a cylindrical tube 4, an adjustment mechanism, and a disassembly / assembly mechanism. A control mechanism is located outside the housing 1 to control the infrared thickness gauge. The cylindrical tube 4 is fixedly connected to the bottom of the housing 1, and a connecting tube 5 is fixedly connected to the bottom of the cylindrical tube 4. A probe 6 is fixedly connected to the end of the connecting tube 5 away from the cylindrical tube 4. A protective lens 11 is movably disposed inside the probe 6. The adjustment mechanism is located inside the connecting tube 5 and is used to adjust the angle of the probe 6. The disassembly / assembly mechanism is located inside the probe 6 and is used to disassemble / assemble the protective lens 11. The protective lens 11 is made of quartz material to prevent foreign objects from entering. In specific use: the probe 6 is in contact with the object being measured for detection. During the detection process, the adjustment mechanism allows the probe 6 to deflect at a certain angle with the surface of the object being measured, ensuring that the probe remains in contact with the object and preventing the detection effect from being affected by the probe 6 not being in contact with the object. Simultaneously, the disassembly / assembly mechanism allows workers to quickly disassemble / assemble the protective lens 11 and distribute workers for maintenance and cleaning of the protective lens 11.

[0031] On one hand, there are multiple adjustment mechanisms arranged at circumferential intervals. The adjustment mechanism includes a first circular rod 8 and a first spring 9. The first circular rod 8 is slidably connected to the inner wall of the circular cylinder 4. A universal ball 10 is fixedly connected to the bottom of the first circular rod 8. The probe 6 is movably adjusted on the outer wall of the universal ball 10. The first spring 9 is fixedly connected between the circular cylinder 4 and the probe 6. In specific use, the multiple universal balls 10 are used to make the probe 6 move with the surface of the object being measured and make a certain angle of displacement. When the probe 6 makes an angle displacement, it squeezes the first circular rod 8 to move along the inner wall of the circular cylinder 4.

[0032] On the other hand, the disassembly and assembly mechanism includes a locking structure and a horizontal drive structure. The locking structure includes a sliding plate 16 and a second fixing plate 20. The sliding plate 16 is slidably connected to the inner wall of the probe 6. A square plate 13 is fixedly connected to the outer wall of the sliding plate 16. A first fixing plate 12 is fixedly connected to the side of the square plate 13 away from the sliding plate 16. The second fixing plate 20 is fixedly connected to the outer wall of the square plate 13 and is located below the first fixing plate 12. A fixing ring 17 is fixedly connected to the inner wall of the probe 6. The sliding plate 16 is slidably connected to the inner wall of the fixing ring 17. An elastic component is provided between the square plate 13 and the probe 6. The horizontal drive structure includes a first trapezoidal plate 14 and a second trapezoidal plate 15. The first trapezoidal plate 14 is fixedly connected to the bottom of the square plate 13. A torsion ring 7 is movably connected to the inner wall of the probe 6. The second trapezoidal plate 15 is fixedly connected to the inner wall of the torsion ring 7. The elastic component includes a second circular rod 18 and a second spring 19. The second circular rod 18 is fixedly connected to the inner wall of the probe 6. The square plate 13 is slidably sleeved on the outer wall of the second circular rod 18. The second spring 19 is fixedly connected to the square plate 13 and the inner wall of the probe 6. The second trapezoidal plate 15 is always arc-shaped. The torsion ring 7 is bolted to the probe 6. When the torsion ring 7 moves into the probe 6, the second trapezoidal plate 15 drives the first trapezoidal plate 14 to move. There are multiple second fixing plates 20 and first fixing plates 12, which are circumferentially spaced. In specific use: when it is necessary to install the protective lens 11, the worker inverts the equipment, presses the protective lens 11 into the inner wall of the fixing ring 17, and then rotates the torsion ring 7 into the probe 6 so that the protective lens 11 abuts against the first fixing plate 12. The torsion ring 7 drives the second trapezoidal plate 15 to move. The second trapezoidal plate 15 presses the first trapezoidal plate 14 to move. The first trapezoidal plate 14 drives the second fixing plate 20 and the first fixing plate 12 to move. Multiple second fixing plates 20 and first fixing plates 12 clamp and fix the protective lens 11 at multiple angles to achieve the purpose of fixing the protective lens 11.

[0033] In addition, a display screen 2 and control buttons 3 are fixedly connected to the outer wall of the housing 1. The display screen 2 is used to display detection data, and the control buttons 3 are used to control the opening and closing of the probe 6. A control circuit board is set inside the housing 1. The control circuit board is connected to the control buttons 3, the probe 6 and the display screen 2 by wires. The probe 6 converts the light signal into an electrical signal, which is displayed by the control circuit board through the display screen 2.

[0034] In specific operation: Multiple omnidirectional balls 10 are used to make the probe 6 move with the surface of the object being measured, resulting in a certain angle of displacement. When the probe 6 deviates at an angle, it squeezes the first circular rod 8 to move along the inner wall of the circular cylinder 4. When it is necessary to install the protective lens 11, the worker inverts the equipment, presses the protective lens 11 into the inner wall of the fixing ring 17, and then rotates the torsion ring 7 into the probe 6, so that the protective lens 11 abuts against the first fixing plate 12. The torsion ring 7 drives the second trapezoidal plate 15 to move, the second trapezoidal plate 15 squeezes the first trapezoidal plate 14 to move, and the first trapezoidal plate 14 drives the second fixing plate 20 and the first fixing plate 12 to move. Multiple second fixing plates 20 and the first fixing plate 12 clamp and fix the protective lens 11 at multiple angles, thereby achieving the purpose of fixing the protective lens 11.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
