Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber sensor fixation, in particular to a fixing structure of an optical fiber sensor. Background Art

[0002] Sensors are developing towards being more sensitive, precise, adaptable, compact, and intelligent. In this process, fiber optic sensors, a new member of the sensor family, are gaining popularity. Fiber optics offer many excellent properties, including resistance to electromagnetic and atomic radiation interference; mechanical properties such as thin diameter, softness, and light weight; electrical insulation and non-inductive properties; and chemical resistance to water, heat, and corrosion. They can act as human eyes and ears in inaccessible locations (such as high-temperature areas) or hazardous areas (such as nuclear radiation zones). They can also transcend human physiological boundaries, receiving external information that is inaccessible to human senses. A fiber optic sensor converts the state of a measured object into a measurable optical signal. The operating principle of a fiber optic sensor is to transmit an incident light beam through an optical fiber into a modulator. Within the modulator, the light interacts with the external measured parameter, causing the optical properties of the light, such as intensity, wavelength, frequency, phase, and polarization state, to change, resulting in a modulated optical signal. This signal is then transmitted through the optical fiber to an optoelectronic device, where it is demodulated to obtain the measured parameter. During the entire process, the light beam is introduced through the optical fiber, passes through the modulator and then emitted. The role of the optical fiber is first to transmit the light beam and secondly to act as a light modulator.

[0003] Currently, most fiber optic sensors use fiber Bragg grating technology. The grating part is very fragile and easy to break. During the repeated use of fiber optic sensors, the bending and stretching forces during installation and disassembly directly act on the rubber sleeve that encapsulates the fiber Bragg grating. Excessive forces during installation and disassembly, as well as excessive bending angles during assembly and disassembly, will affect the service life of the optical fiber and may even cause breakage, affecting its use. Utility Model Content

[0004] In response to the above technical problems, the utility model provides a fixing structure for an optical fiber sensor, which is characterized by comprising an installation fixing structure, a tightening structure, a mounting structure, and an adhesive structure. The tightening structure is installed above the installation fixing structure, the mounting structure is installed above the tightening structure, and the adhesive structure is installed on the back of the installation fixing structure.

[0005] The installation and fixing structure is composed of a fixing buckle, a flip cover, a rotating baffle mounting shaft, a rotating baffle, and an optical fiber placement slot. An optical fiber prevention slot is set inside the fixing buckle, a flip cover is installed on the side of the optical fiber placement slot, a rotating baffle mounting shaft is installed above the flip cover, and a rotating baffle is installed on the top of the rotating baffle mounting shaft.

[0006] The tightening structure is composed of a bolt tightening seat and a bolt hole. The bolt hole is provided inside the bolt tightening seat.

[0007] The mounting structure is composed of a hook mounting seat and a hook, and a hook is installed above the hook mounting seat.

[0008] The adhesive structure consists of back adhesive and back tear paper, and the back tear paper is arranged on the outer side of the back adhesive.

[0009] Beneficial effects of the utility model:
