Description

Technical Field

[0001] This utility model relates to the field of fiber optic sensing technology, specifically to a fiber optic sensor mounting structure. Background Technology

[0002] Fiber optic sensors have been widely used in many industrial and civilian monitoring fields due to their advantages such as strong anti-electromagnetic interference capability, high sensitivity, ability to achieve distributed measurement, and corrosion resistance. However, in actual installation, the existing installation structure has many problems, which seriously affect the installation quality of fiber optic sensors and the subsequent monitoring effect. Therefore, it is particularly important to develop a fiber optic sensor installation structure.

[0003] Referring to the mounting structure of an optical fiber sensor with publication number CN220490096U, it includes a base plate and a mounting mechanism. The base plate has fixing parts on both sides of its top end. A placement component is located inside the fixing part. The mounting mechanism is located in front of the placement component. The mounting mechanism includes a support component, a rotating component, a moving component, and a mounting element. The support component is located in front of the placement component, the rotating component is located inside the support component, and the moving component is located at the top of the rotating component. First, the rotating bar is adjusted to a suitable angle, and then the rotating cover is screwed in along the external thread, causing the contraction opening to be squeezed and contracted. This causes the inner rotating column to be compressed, thereby fixing the rotating column. Adjust the position of the moving block so that the adjusting hole is aligned with the fixing hole, then insert the bolt and install the fiber optic sensor head into the mounting hole according to its diameter. This mounting structure allows for free adjustment of the angle and distance of the fiber optic sensor head, and is simple and practical. As can be seen from the above, although this mounting structure can be well applied to meet the installation requirements of fiber optic sensors, it is usually inconvenient to adjust the angle of the fiber optic sensor, making it difficult for the signal reception and transmission efficiency of the fiber optic sensor to reach the expected level, which often troubles users.

[0004] The purpose of this utility model is to provide a fiber optic sensor mounting structure to solve the problem that although the mounting structure proposed in the background art can be well applied to meet the installation requirements of fiber optic sensors, it is usually inconvenient to adjust the angle of the fiber optic sensor, making it difficult for the signal reception and transmission efficiency of the fiber optic sensor to reach the expected level.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fiber optic sensor mounting structure, including an upper connecting plate, a lower connecting plate below the upper connecting plate, a top seat installed at the center of the bottom end of the lower connecting plate, a plurality of upper connecting seats fixed at the bottom end of the top seat, a lower connecting seat installed on the right side of each upper connecting seat, the outer walls of adjacent lower connecting seats and upper connecting seats touching each other, a rotating shaft rotatably mounted between the plurality of upper connecting seats and lower connecting seats, a rectangular frame fixed at the bottom end of the plurality of lower connecting seats, a fiber optic sensor body installed inside the rectangular frame, both ends of the fiber optic sensor body extending to the outside of the rectangular frame, and a sensor interface provided on the outer wall of one side of the fiber optic sensor body.

[0006] Preferably, two first locking bolts are installed on the outer wall of one side of the rectangular frame. One end of the first locking bolt passes through the rectangular frame and is threadedly connected to the outer wall of the fiber optic sensor body. The first locking bolts are provided to facilitate the disassembly and assembly of the fiber optic sensor body.

[0007] Preferably, two second locking bolts are installed on the outer wall of the rectangular frame away from the first locking bolt. One end of the second locking bolt passes through the rectangular frame and is threadedly connected to the outer wall of the fiber optic sensor body. The second locking bolts are provided to facilitate the disassembly and assembly of the fiber optic sensor body.

[0008] Preferably, a third locking bolt is installed on both sides of the top of the rectangular frame. The bottom end of the third locking bolt passes through the rectangular frame and is threadedly connected to the top of the fiber optic sensor body. The third locking bolt is provided to facilitate the disassembly and assembly of the fiber optic sensor body.

[0009] Preferably, a fourth locking bolt is installed on both sides of the bottom end of the top seat. The top end of the fourth locking bolt passes through the top seat and is threadedly connected to the bottom end of the lower connecting plate. The fourth locking bolt is provided to facilitate the disassembly and assembly of the top seat.

[0010] Preferably, a plurality of pin cylinders are installed between the upper connecting plate and the lower connecting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the fiber optic sensor mounting structure can not only adjust the tilt angle of the fiber optic sensor body as needed to improve the signal transmission and reception efficiency of the fiber optic sensor body, but also achieve the purpose of easy disassembly and maintenance of the fiber optic sensor body, and also achieve the purpose of easy and stable installation of the fiber optic sensor body.

[0012] (1) The upper and lower connecting seats are rotatably mounted on the outer wall of the rotating shaft, and the outer walls of adjacent upper and lower connecting seats are in contact. By simply rotating the fiber optic sensor body so that the lower connecting seat is located on the outer wall of the upper connecting seat, the tilt angle of the fiber optic sensor body can be adjusted as needed, thereby improving the signal transmission and reception efficiency of the fiber optic sensor body.

[0013] (2) By setting the first locking bolt, the second locking bolt and the third locking bolt, the fiber optic sensor body can be locked and placed inside the rectangular frame, or the fiber optic sensor body can be removed to the outside of the rectangular frame. Because of the setting of the fourth locking bolt, the top seat can be disassembled and installed at the bottom of the lower connecting plate. Thus, the fiber optic sensor body can be disassembled and installed without the need for the overall disassembly and installation structure, thereby achieving the purpose of easy disassembly and maintenance of the fiber optic sensor body.

[0014] (3) By setting up several pin cylinders, the entire installation structure can be wall-mounted by simply using bolts to pass through the pin holes and screw them into the mounting housing or mounting wall, thereby achieving the purpose of easy and stable installation of the fiber optic sensor body.

A fourth locking bolt 12 is installed on both sides of the bottom end of the top seat 8. The top of the fourth locking bolt 12 passes through the top seat 8 and is threadedly connected to the bottom end of the lower connecting plate 2.

[0024] In use, the top seat 8 can be disassembled and assembled by the fourth locking bolt 12.

[0025] Several upper connecting seats 9 are fixed at the bottom of the top seat 8. A lower connecting seat 10 is installed on the right side of each upper connecting seat 9. The outer walls of adjacent lower connecting seats 10 and upper connecting seats 9 are in contact. A rotating shaft 11 is rotatably installed between several upper connecting seats 9 and lower connecting seats 10. A rectangular frame 5 is fixed at the bottom of several lower connecting seats 10. Two first locking bolts 7 are installed on the outer wall of one side of the rectangular frame 5. One end of the first locking bolt 7 passes through the rectangular frame 5 and is threadedly connected to the outer wall of the fiber optic sensor body 6.

[0026] In use, the first locking bolt 7 is used to facilitate the disassembly and assembly of the fiber optic sensor body 6.

[0027] Two second locking bolts 13 are installed on the outer wall of the rectangular frame 5 on the side away from the first locking bolt 7. One end of the second locking bolt 13 passes through the rectangular frame 5 and is threadedly connected to the outer wall of the fiber optic sensor body 6.
