Technical Field
[0001] This utility model relates to the field of fiber optic sensor technology, specifically to a steel component fiber optic sensor that is easy to disassemble and replace. Background Technology
[0002] Fiber optic sensors are needed when assembling steel components. A fiber optic sensor is a sensor that converts the state of the object being measured into a measurable light signal.

The installation and fixing structure of the display screen and the electrical connection structure have been optimized to achieve efficient and automated assembly of the display screen in the fiber optic sensor. Simultaneously, the dimensional accuracy requirements of the electrical connection structure are reduced, further lowering production costs and improving manufacturing efficiency. The fiber optic sensor includes a housing, a circuit board, a display screen, and electrical connectors. The housing has a bottom surface and a side surface, with a portion of the side surface configured as a fixing groove perpendicular to the bottom surface. The circuit board is equipped with... On the inner side of the bottom surface, the circuit board surface is provided with display screen electrical connection terminals; the display screen is embedded in the fixing groove in a direction perpendicular to the bottom surface; the electrical connector is electrically connected at one end to the side of the display screen extending along the length direction, and the other end is bent and extended laterally to be electrically connected to the display screen electrical connection terminals. However, most of these fiber optic sensors achieve connection by friction between the protective layer on the surface of the fiber and the inner wall of the sensor slot. This causes the fiber optic sensor to be prone to fiber optic detachment when subjected to external force, and force is required to insert the fiber into the sensor when plugging it in, which reduces the practicality of the fiber optic sensor.
[0004] Therefore, it is necessary to improve the fiber optic sensor to prevent it from coming loose when the fiber optic cable is plugged in. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 4 As shown, the present invention provides a steel component fiber optic sensor that is easy to disassemble and replace, including sensor 1;
[0023] Two optical fibers 2 are provided on the front side of the sensor 1. The rear side of the optical fibers 2 extends into the interior of the sensor 1 and contacts the inner wall of the sensor 1. Movable grooves 3 are provided on both sides of the sensor 1. A connecting plate 4 is provided inside the movable groove 3. A rotating rod 5 is fixedly connected inside the connecting plate 4. The outer side of the rotating rod 5 extends into the interior of the sensor 1 and is movably connected to the inner wall of the sensor 1. A clamping plate 6 is fixedly connected to the front side of the connecting block 11. The end of the clamping plate 6 away from the connecting block 11 passes through the movable groove 3 and is sleeved on the surface of the optical fiber 2. The surface of the clamping plate 6 is slidably connected to the inner wall of the movable groove 3. The opposite sides of the clamping plates 6 are in contact with each other.
[0024] refer to Figure 3Both sides of the sensor 1 are fixedly connected to a transmission box 7. The transmission box 7 has a sliding groove 8 inside. A moving block 9 is slidably connected inside the sliding groove 8. An insert plate 10 is fixedly connected to the front side of the moving block 9. The front side of the insert plate 10 passes through the transmission box 7 and extends to the surface of the card plate 6. The end of the insert plate 10 away from the moving block 9 contacts the surface of the card plate 6. A connecting block 11 is fixedly connected to the end of the moving block 9 away from the sensor 1. The end of the connecting block 11 away from the moving block 9 passes through to the outside of the transmission box 7 and is fixedly connected to a push block 12. The end of the push block 12 close to the transmission box 7 is slidably connected to the surface of the transmission box 7.
[0025] As a technical optimization of this utility model, by setting up a transmission box 7, a sliding groove 8, a moving block 9, an insert plate 10, a connecting block 11, and a push block 12, the card plate 6 can be limited, thus preventing the card plate 6 from automatically flipping during the limiting process.
[0026] refer to Figure 3 The inside of the slide 8 is horizontally fixedly connected to two guide rods 13, which pass through the moving block 9 and are slidably connected to the moving block 9.
[0027] As a technical optimization of this utility model, by setting the guide rod 13, the push block 12 can be guided to prevent the push block 12 from tilting and getting stuck when moving.
[0028] refer to Figure 3 A spring return device 14 is sleeved on the surface of the guide rod 13. The front side of the spring return device 14 contacts the rear side of the moving block 9, and the rear side of the spring return device 14 contacts the rear side of the inner wall of the slide groove 8.
[0029] As a technical optimization of this utility model, by setting the rebound device 14, the push block 12 can be moved inward automatically, which improves the practicality of the push block 12.
[0030] refer to Figure 1 A friction sleeve 15 is fixedly connected to the end of the card plate 6 away from the connecting plate 4, and the inner wall of the friction sleeve 15 is in contact with the surface of the optical fiber 2.
[0031] As a technical optimization of this utility model, by setting the friction sleeve 15, the contact between the card plate 6 and the surface of the optical fiber 2 can be made tighter, thereby increasing the contact area between the card plate 6 and the optical fiber 2.
[0032] refer to Figure 4 Two torsion springs 16 are sleeved on the surface of the rotating rod 5. The outer side of the torsion spring 16 is fixedly connected to the inner wall of the movable groove 3, and the inner side of the torsion spring 16 is fixedly connected to the surface of the connecting plate 4.
[0033] As a technical optimization of this utility model, by setting the torsion spring 16, the connecting plate 4 can be automatically flipped outward, avoiding the phenomenon that the user needs to manually flip the card plate 6 outward, thus improving the user's comfort.
[0034] The working principle and usage process of this utility model are as follows: When in use, first insert the optical fiber 2 into the inside of the sensor 1. After insertion, the user flips the card plate 6 inward. The card plate 6 drives the connecting plate 4 sleeved on the surface of the rotating rod 5 to flip inward, so that the card plate 6 is pressed against the surface of the optical fiber 2. After pressing, the pusher 12 is pushed to move the connecting block 11 forward. The connecting block 11 drives the pusher 12 to move forward. The pusher 12 drives the insert plate 10 to move forward, so that the insert plate 10 moves to the surface of the card plate 6 and limits the card plate 6. Finally, if it is necessary to remove the optical fiber 2, the above operation can be reversed.
[0035] In summary, this easily replaceable steel-framed fiber optic sensor, by using a retaining plate 6, can initially limit the fiber optic cable 2, preventing it from naturally detaching during use. The rotating rod 5 and connecting plate 4 allow the retaining plate 6 to be flipped, facilitating quick insertion of the fiber optic cable. The moving block 9, insertion plate 10, connecting block 11, and push block 12 further limit the retaining plate 6, preventing it from automatically flipping during use. This design facilitates easy replacement and solves the problem that most fiber optic sensors rely on friction between the protective layer on the fiber optic surface and the inner wall of the sensor slot for connection. This often leads to fiber optic cable detachment when subjected to external force, and requires force to insert the cable, reducing the sensor's practicality.
