Description

Technical Field

[0001] This utility model relates to the field of fiber optic probe manufacturing and processing technology, and in particular to an adjustable fluorescent fiber optic probe. Background Technology

[0002] A fiber optic probe is a sensor device based on fiber optic technology. It utilizes the characteristics of optical fibers to detect and measure various physical, chemical, or biological quantities. It has the potential for multi-parameter measurement. For example, some composite fiber optic probes can simultaneously measure temperature and strain. By analyzing different characteristics of the optical signal, such as wavelength and intensity, information on multiple physical quantities can be obtained.

[0003] Traditional fluorescent fiber optic probes have a relatively simple structure design, low cost, and are easy to mass-produce. However, traditional fluorescent fiber optic probes cannot freely adjust the probe length, which makes them unsuitable for complex detection environments and greatly exacerbates the limitations of fiber optic probe use. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an adjustable fluorescent fiber optic probe, which aims to improve the problem that traditional fluorescent fiber optic probes cannot freely adjust the probe length, thus making them unsuitable for complex detection environments and greatly exacerbating the limitations of fiber optic probe use.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An adjustable fluorescence fiber optic probe includes a first housing, a second housing slidably connected to the inner wall of the first housing, a support assembly provided on the inner wall of the second housing, a spring piece fixedly connected to the outer wall of the support assembly, a first sliding post fixedly connected to the outer wall of the spring piece, a fiber optic probe body fixedly connected to the inner wall of the second housing, a sliding hole provided on the inner wall of the first housing, and the outer wall of the first sliding post slidably connected to the inner wall of the first housing through the sliding hole.

[0007] Preferably, the support assembly includes a fixed column, the outer wall of which is fixedly connected to the inner wall of the second housing, and a collar is fixedly connected to the outer wall of the fixed column.

[0008] Preferably, a stop is fixedly connected to the outer wall of the first housing, a fixing block is fixedly connected to the outer wall of the stop, a transmission component is provided on the inner wall of the fixing block, the outer wall of the transmission component is slidably connected to the inner wall of the stop, a second sliding column is slidably connected to the outer wall of the transmission component, and a protective sleeve is fixedly connected to the upper surface of the second sliding column.

[0009] Preferably, the transmission assembly includes a spring, the outer wall of which is disposed on the inner wall of the fixed block, and a sliding block is fixedly connected to the outer wall of the spring.

[0010] Preferably, the inner wall of the fixed block is provided with a sliding groove, and the outer wall of the sliding block is slidably connected to the inner wall of the fixed block through the sliding groove.

[0011] Preferably, the inner wall of the stop block is provided with a third hole, and the outer wall of the sliding block is slidably connected to the inner wall of the stop block through the third hole.

[0012] Preferably, the inner wall of the stop block is provided with a second hole, and the outer wall of the second sliding column is slidably connected to the inner wall of the stop block through the second hole.

[0013] Preferably, the inner wall of the second sliding column is provided with a first hole, and the outer wall of the sliding block is slidably connected to the inner wall of the second sliding column through the first hole.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the first sliding post is pressed to drive the spring to rotate. After the first sliding post is pressed, the first outer shell is slid, so that the first outer shell slides on the outer wall of the first sliding post. When the first outer shell slides to the appropriate position, the spring will pop out the first sliding post, so that the first sliding post is fixed to the inner wall of the first outer shell through the sliding hole. This realizes the adjustment of the length of the fiber optic probe body, so that the fiber optic probe body can adapt to the needs of different environments and greatly improve the efficiency of the fiber optic probe body.

[0016] 2. In this utility model, when the fiber optic probe body is placed for a long time, firstly, the sliding block is slid to compress the spring. When the sliding block slides to a suitable position, the sliding block is rotated to fix the sliding block to the inner wall of the fixed block through the sliding groove. At this time, the protective sleeve is moved to drive the second sliding column to slide to the inner wall of the stop block through the second hole. Then, the sliding block is rotated to make the spring pop out the sliding block to the inner wall of the stop block and the second sliding column, thereby achieving the effect of fixing the protective sleeve to the outside of the fiber optic probe body and preventing the surface of the fiber optic probe body from being worn by external force.

[0026] Specifically, pressing the first sliding post 7 will cause the spring 6 to rotate due to the fixing action of the first sliding post 7 and the spring 6. After pressing the spring 6, the first outer shell 1 will slide. When the first outer shell 1 is slid to the appropriate position, the spring 6 will pop out the first sliding post 7, so that the first sliding post 7 is fixed to the inner wall of the first outer shell 1 through the sliding hole 2, thereby achieving the effect of adjusting the length of the fiber optic probe body 8.

[0027] Reference Figure 1 , Figure 4 and Figure 5The support assembly includes a fixed column 4, the outer wall of which is fixedly connected to the inner wall of the second outer shell 3, and a collar 5 is fixedly connected to the outer wall of the fixed column 4; a stop block 9 is fixedly connected to the outer wall of the first outer shell 1, a fixed block 10 is fixedly connected to the outer wall of the stop block 9, a transmission assembly is provided on the inner wall of the fixed block 10, the outer wall of the transmission assembly is slidably connected to the inner wall of the stop block 9, a second sliding column 15 is slidably connected to the outer wall of the transmission assembly, and a protective sleeve 14 is fixedly connected to the upper surface of the second sliding column 15; the transmission assembly includes a spring 11, the outer wall of the spring 11 is provided on the inner wall of the fixed block 10, and a sliding block 12 is fixedly connected to the outer wall of the spring 11; a groove 13 is provided on the inner wall of the fixed block 10, and the outer wall of the sliding block 12 is slidably connected to the inner wall of the fixed block 10 through the groove 13;

[0028] Specifically, the fixed column 4 is used to support the collar 5, the stop block 9 is used to support the fixed block 10, the fixed block 10 is used to support the spring 11 and the sliding block 12, the spring 11 is used to reset the sliding block 12, and the slide groove 13 is used to limit the running trajectory of the sliding block 12.

[0029] Reference Figure 4 and Figure 5 The inner wall of the stop block 9 has a third hole 18, and the outer wall of the sliding block 12 is slidably connected to the inner wall of the stop block 9 through the third hole 18; the inner wall of the stop block 9 has a second hole 17, and the outer wall of the second sliding column 15 is slidably connected to the inner wall of the stop block 9 through the second hole 17; the inner wall of the second sliding column 15 has a first hole 16, and the outer wall of the sliding block 12 is slidably connected to the inner wall of the second sliding column 15 through the first hole 16.

[0030] Specifically, the stop block 9 is used to keep the first hole 16 and the third hole 18 on the same horizontal line, the second hole 17 is used to restrict the running trajectory of the second sliding column 15, and the sliding block 12 fixes the second sliding column 15 to the inner wall of the stop block 9 through the third hole 18 and the first hole 16. Through the fixing action of the second sliding column 15 and the protective sleeve 14, the protective sleeve 14 is fixed to the outer wall of the fiber optic probe body 8, so as to prevent the fiber optic probe body 8 from being worn on the surface due to external force, thus affecting the quality of use.

[0031] Working principle: When the fluorescent fiber optic probe needs to be adjusted, firstly press the first sliding post 7. The first sliding post 7 will drive the spring 6 to rotate on the outer wall of the collar 5. After pressing the first sliding post 7, slide the first outer shell 1, causing the first outer shell 1 to slide up and down on the outer wall of the second outer shell 3. When the first outer shell 1 slides to the appropriate position, the spring 6 will pop out the first sliding post 7, allowing the first sliding post 7 to pass through the sliding hole 2 opened on the inner wall of the first outer shell 1 and be fixed to the inner wall of the first outer shell 1, thereby achieving the effect of length adjustment of the fiber optic probe body 8. When the fluorescent fiber optic probe needs to be placed for a long time, firstly slide the sliding block 12. When the sliding block 12 slides, it will compress the spring 11. When the sliding block 12 slides to the appropriate position, rotate the sliding block 12 to fix the sliding block 12 to the fixed position through the sliding groove 13. The inner wall of the fixed block 10 is then slid, and the second sliding column 15 is slid through the second hole 17 to the inner wall of the stop block 9. The stop block 9 can keep the third hole 18 and the first hole 16 on the same horizontal line. Then, the sliding block 12 is rotated, and the spring 11 will pop out the sliding block 12, so that the sliding block 12 is fixed to the inner wall of the stop block 9 and the second sliding column 15 through the third hole 18 and the first hole 16, thereby fixing the protective sleeve 14 to the outside of the fiber optic probe body 8. Finally, the fluorescent fiber optic probe can not only adjust the length of the fiber optic probe body 8 by sliding the first outer shell 1, but also fix the sliding block 12 to the inner wall of the stop block 9 and the second sliding column 15, thereby setting the protective sleeve 14 on the outside of the fiber optic probe body 8, preventing the fiber optic probe body 8 from being worn by external forces.
