[0002] The planar diffuse reflection fiber optic sensor includes a planar body and a working surface disposed on one side of the planar body. A fiber optic bundle is connected to one side of the planar body. The working surface is arranged with one emitting fiber and one receiving fiber at intervals, and the receiving fiber and the emitting fiber are perpendicular to the working surface. During operation, due to the working mechanism of the diffuse reflection fiber optic sensor, the working surface needs to be parallel to the surface of the object to be measured.

[0003] Therefore, when installing a flat-panel diffuse reflection fiber optic sensor, a mounting reference surface or mounting reference component is required for the sensor body to be installed. However, in actual applications, due to manufacturing errors, the reference surface, reference component, and flat-panel sensor body will all have certain dimensional errors. Therefore, after installation, the flat-panel sensor body needs to be fine-tuned according to the actual detection effect. Currently, the fine-tuning method is mostly to adjust the reference surface or reference component, which is not convenient enough and has low adjustment efficiency. Utility Model Content

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] Please refer to Figure 1-5 As a specific implementation, this utility model provides a flat-plate supported diffuse reflection fiber optic 10 sensor for convenient installation, which includes a mounting reference component 2 and a flat plate body 1. The flat plate body 1 includes a working surface 13. The mounting reference component 2 includes a plate body 20 and a connecting rod 21 disposed on the plate body 20. The connecting rod 21 includes a connecting section 210. It also includes an adjustment assembly 3 detachably connected to the connecting rod 21. The adjustment assembly 3 includes: The connecting plate 31 is detachably connected to the connecting section 210, the adjusting plate 30 is connected to the connecting hinge, and two adjusting screws 34 are threadedly connected to the connecting plate 31 and located on both sides of the hinge. The ends of the adjusting screws 34 abut against the adjusting plate 30. The hinge axis of the connecting plate 31 and the adjusting plate 30 is parallel to the axis of the connecting section 210. The flat body 1 is disposed on the adjusting plate 30.

[0027] Specifically, in this application, the flat plate body is consistent with that described in the background art. It includes a working surface 13 for setting the light-emitting optical fiber 10 and the light-receiving optical fiber 10, and is provided with optical fiber 10. It also includes a mounting reference component 2, which includes a metal plate body 20 and a connecting rod 21. The connecting rod 21 includes a connecting section 210 arranged parallel to the plate body 20. In the adjustment assembly 3, the connecting plate 31 is detachably connected to the connecting section 210. The adjustment plate 30 is hinged to the connecting plate 31. Two adjustment screws 34 are threadedly connected to the connecting plate 31 and located on both sides of the hinge part. Their ends abut against the adjustment plate 30. The hinge axis of the connecting plate 31 and the adjustment plate 30 is parallel to the axis of the connecting section 210. The flat plate body 1 is mounted on the adjustment plate 30. With this structural design, when installing the flat plate body 1, it is first fixed to the equipment frame by the plate body 20, and the axis of the connecting section 210 is parallel to the surface of the object to be measured. Then, the adjustment component 3 is installed on the connecting section 210, and the plate body is installed on the adjustment plate 30. Through the installation and positioning of the plate body and the adjustment plate 30, the working surface 13 is also roughly parallel to the axis of the connecting section 210. At this time, by rotating the adjustment plate 30 around the axis of the connecting section 210, the mounting surface is roughly parallel to the surface of the object to be measured. Then, the posture of the adjustment plate 30 can be finely adjusted by rotating the adjustment screws 34 on both sides. Since the end of the adjusting screw 34 abuts against the adjusting plate 30, when one adjusting screw 34 is screwed in, it will push the adjusting plate 30 to rotate around the hinge axis to the other side. When the adjusting screw 34 on that side is screwed out, the adjusting screw 34 on the other side can push the adjusting plate 30 to rotate in the opposite direction under the action of the adjusting plate 30 itself or external force, thereby realizing the fine adjustment of the angle of the flat body 1. The adjustment process directly acts on the adjusting component 3, which is convenient to operate and can effectively improve the adjustment efficiency, solving the problems of inconvenient and inefficient adjustment methods in the background technology.

[0028] Furthermore, as a specific implementation, the side of the connecting plate 31 opposite to the adjusting plate 30 is provided with a clamping groove 32, and an arc-shaped clamping plate 33 is detachably provided on the top of the clamping groove 32.

[0029] Specifically, the connecting plate 31 and the clamping groove 32 are integrally formed. The axis of the clamping groove 32 is parallel to the axis of the hinge shaft and also parallel to the surface of the adjusting plate 30. The cooperation between the clamping groove 32 and the arc-shaped clamping plate 33 can more stably realize the detachable connection between the connecting plate 31 and the connecting section 210 of the connecting rod 21. Furthermore, by clamping and positioning the connecting section 210 with the clamping groove 32, it can be ensured that the axis of the hinge shaft is parallel to the connecting section 210. This method facilitates connection and fixation, provides flexible assembly, and also facilitates clamping and positioning.

[0030] Furthermore, as a specific implementation method, refer to Figure 5 - Figure 8 The connecting plate 31 has a second ear plate 310 on its surface, and the adjusting plate 30 has a first ear plate 302 corresponding to the second ear plate 310. The first ear plate 302 and the second ear plate 310 are rotatably connected by a pin 303. Specifically, the cooperation between the first ear plate 302, the second ear plate 310 and the pin 303 provides a stable and reliable hinge structure for the connecting plate 31 and the adjusting plate 30. This structure is simple and easy to manufacture, ensuring smooth rotation of both around the axis of the pin 303 (i.e., the hinge axis), avoiding jamming or loosening at the hinge, ensuring the accuracy and stability of the angle adjustment of the adjusting plate 30, and providing a structural basis for the effective fine-tuning of the angle of the flat plate body 1.

[0031] Furthermore, as a preferred embodiment, a spring 35 is also provided between the connecting plate 31 and the adjusting plate 30 on one side of the pin 303, with the two ends of the spring 35 abutting against the adjusting plate 30 and the connecting plate 31 respectively.

[0032] Specifically, by setting a spring 35, the spring 35 can provide a spring force to the adjusting plate 30 to rotate around the hinge axis. With this setting, when it is necessary to deflect the angle of the adjusting plate 30, simply loosen the adjusting screw 34 on the same side as the spring 35, and then adjust the adjusting screw 34 on the other side. When the adjusting screw 34 on the other side is turned away from the adjusting plate 30, the spring force of the spring 35 causes the adjusting plate 30 to rotate synchronously and always abut against the end of the adjusting screw 34 on the other side, ensuring the sensitivity and timeliness of the adjustment, and avoiding the problem of loosening or displacement after angle adjustment due to the gap between the adjusting plate 30 and the adjusting screw 34. When the adjusting screw 34 is rotated for adjustment, the spring force of the spring 35 will cooperate with the pushing or pulling force of the adjusting screw 34, so that the position of the adjusting plate 30 can quickly respond to the adjustment action, improving the sensitivity and accuracy of the adjustment, and also enhancing the stability of the overall structure during operation.

[0033] For details, please refer to Figure 6Each adjusting screw 34 is equipped with a locking nut 340. By setting the locking nut 340, after the adjusting screw 34 is adjusted to the appropriate position, the position of the adjusting screw 34 can be locked by locking the locking nut 340.

[0034] Furthermore, as a preferred embodiment, reference continues to be made to... Figure 5 - Figure 8 The adjusting plate 30 has a groove 300 corresponding to the spring 35 on its surface, and the connecting plate 31 has a groove 314 corresponding to the spring 35 on its surface. The two ends of the spring 35 abut against the bottom surfaces of the groove 300 and the groove 314, respectively.

[0035] Specifically, groove 300 and groove 314 position and limit the spring 35, preventing it from shifting laterally or falling off during compression or extension, ensuring that the spring 35 always functions in the predetermined position. This design ensures that the force exerted by the spring 35 on the adjusting plate 30 and the connecting plate 31 is stable, further enhancing the effect of the spring 35 in assisting adjustment and stabilizing the structure.

[0036] Furthermore, the edge of the flat body 1 is provided with threaded holes 11, and the adjusting plate 30 is provided with screws 301 that correspond one-to-one with the threaded holes 11.

[0037] Specifically, the adjusting plate 30 has a plate-like structure. Through the engagement of screws 301 and threaded holes 11, the flat plate body 1 can be firmly fixed to the adjusting plate 30, ensuring their relative positional relationship. Simultaneously, the threaded connection facilitates the installation and disassembly of the flat plate body 1. When it is necessary to replace or maintain the flat plate body 1, simply unscrew the screws 301. This simple and convenient operation improves the equipment's maintenance efficiency.

[0038] Furthermore, as a specific implementation method, refer to Figure 1 - Figure 4 , Figure 9 The connecting rod 21 also includes a mating section 211 that is perpendicular to the connecting end. The mating section 211 is perpendicular to the plate 20 and is rotatably mated.

[0039] Specifically, the mating section 211 is perpendicular to and rotatably fitted with the plate body 20, and is also perpendicular to the connecting section 210. The rotatable fit between the mating section 211 and the plate body 20 allows the connecting rod 21 to rotate around the axis of the mating section 211 (perpendicular to the plate body 20), thereby causing the connecting section 210, the adjusting component 3, and the flat plate body 1 to rotate together, achieving angle adjustment of the flat plate body 1. This structure expands the adjustment dimensions of the flat plate body 1, allowing not only fine-tuning of the angle via the adjusting component 3 but also a wider range of horizontal angle adjustments via the rotation of the connecting rod 21, better adapting to different installation and testing needs and improving the applicability of the equipment.

[0040] Furthermore, as a specific implementation method, refer to Figure 9 The plate 20 has a locking assembly 4 on its side for adapting to the mating section 211. The locking assembly 4 includes a locked state for locking the mating section 211 and a released state for releasing the mating section 211. Specifically, the plate 20 has a locking assembly 4 on its side for adapting to the mating section 211, and the locking assembly 4 has a locked state for locking the mating section 211 and a released state for releasing the mating section 211. When it is necessary to adjust the rotation angle of the connecting rod 21, the locking assembly 4 is switched to the released state, and the mating section 211 can rotate freely; after the angle adjustment is completed, the locking assembly 4 is switched to the locked state, and the mating section 211 is fixed and cannot rotate, thus ensuring the stability of the position of the connecting rod 21 and subsequent structures. The locking assembly 4 enables precise positioning of the rotation adjustment of the connecting rod 21, preventing accidental rotation of the mating section 211 during operation from affecting the working position of the flat plate body 1, and ensuring the accuracy of the detection.

[0041] Furthermore, as a specific implementation method, refer to Figure 9 The plate body 20 includes a first hole 200 that rotatably engages with the mating section 211. A second hole 202 that intersects with the first hole 200 is provided on the side of the plate body 20. A threaded blind hole 201 is provided at the end of the second hole 202. The locking assembly 4 includes a locking pin 40 that is guided and disposed in the second hole 202 and a locking screw 41 that is threadedly connected to the threaded blind hole 201. The lower end of the locking screw 41 abuts against the locking pin 40.

[0042] Specifically, the plate 20 includes a first hole 200 that rotatably engages with the mating section 211. The side of the plate 20 has a second hole 202 that intersects with the first hole 200. The end of the second hole 202 has a threaded blind hole 201. The locking assembly has the following structure: it includes a locking pin 40 guided within the second hole 202 and a locking screw 41 threadedly connected to the threaded blind hole 201. The lower end of the locking screw 41 abuts against the locking pin 40. When it is necessary to lock the mating section 211, the locking screw 41 is tightened, pushing the locking pin 40 to move within the second hole 202 until the locking pin 40 and the mating section 211 in the first hole 200 are tightly abutted, fixing the mating section 211 through friction. When it is necessary to release the mating section 211, the locking screw 41 is loosened, releasing the pressure on the locking pin 40, allowing the mating section 211 to rotate freely. This locking structure is simple, reliable, and easy to operate. It can effectively lock and release the mating section 211, ensuring the convenience of rotating and adjusting the connecting rod 21 and the stability of its positioning.

[0043] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
