[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The embodiment of the utility model discloses a detection device for a fiber Bragg grating demodulation system.

[0028] Example 1

[0029] The utility model provides Figure 1-4 The fiber Bragg grating demodulation system detection device shown includes a storage rack 1, a detection platform 2 is fixedly provided on the top of the storage rack 1, a sliding hole 3 is opened on the upper end of the side of the detection platform 2, a slider 4 is slidably penetrated inside the sliding hole 3, a rotating rod 5 is rotatably penetrated inside the slider 4, a connecting plate 6 is fixedly sleeved on the front end of the rotating rod 5, a plurality of connecting racks 7 arranged in a symmetrical manner are fixed on the outer side of the connecting plate 6, a standard test single board 8 is provided at the end of the connecting rack 7, the connecting rack 7 is arranged in a T shape, and a mounting bolt 17 is screwed between the connecting rack 7 and the standard test single board 8, and the specifications of the plurality of standard test single boards 8 are different.

[0030] Before inspecting the internal components of the fiber grating adjustment system, multiple standard test boards 8 of different specifications are installed on the surface of the connecting frame 7 according to the components to be inspected, and multiple components to be inspected are placed in the storage rack 1. When performing the inspection, the components are placed at the lower end of the interior of the inspection table 2. At this time, the standard test board 8 of the corresponding specifications is determined according to the components, and the rotating rod 5 is rotated so that the rotating rod 5 rotates inside the slider 4. At this time, under the connection between the connecting plate 6 and the connecting frame 7, multiple standard test boards 8 can be rotated and replaced to stably cooperate with the components to be tested. After the position of the standard test board 8 is determined, the standard test board 8 can be moved down and contacted with the components to complete the inspection.

[0031] Example 2

[0032] Example 2 is based on Example 1 in order to make the standard test board 8 move downward stably after positioning and cooperate with the components to complete the test, such as Figure 2-3 As shown, the back side of the slider 4 is provided with a downward support mechanism for supporting the movement of the slider 4. The downward support mechanism includes two symmetrically arranged support frames 9. The two support frames 9 are U-shaped support frames. The two support frames 9 are located on both sides of the sliding hole 3 and are fixedly connected to the back side of the detection table 2. Guide rings 10 are fixedly provided on both sides of the rear end of the slider 4. The guide rings 10 are slidably sleeved on the outside of the support frame 9. The outer lower end of the support frame 9 is sleeved with a spring 11. The two ends of the spring 11 are fixedly connected to the support frame 9 and the guide ring 10 respectively.

[0033] After the position of the standard test board 8 is determined, the slider 4 can be moved downward. At this time, the slider 4 is restricted by the sliding hole 3. At the same time, with the sliding cooperation of the guide ring 10 and the support frame 9, the slider 8 drives multiple standard test boards 8 to move downward stably and contact with the component to be tested and complete the detection work. At the same time, under the elastic force of the spring 11, after the detection work is completed, the guide ring 10, the slider 4 and the standard test board 8 can be pushed back to their original position by the elastic force of the spring 11, which is convenient for subsequent continuous detection of the component to be tested.

[0034] Example 3

[0035] Example 3 is based on Example 1 in order to determine the position of the standard test board 8 before and after the standard test board 8 is rotated, so as to ensure the stable performance of the test work. Figure 2-3 As shown, the rear end of the rotating rod 5 is provided with a rotation positioning mechanism for limiting the position of the standard test board 8. The rotation positioning mechanism includes a mounting ring 12, which is fixedly mounted on the lower end of the back side of the slider 4. The surface of the mounting ring 12 is provided with a plurality of symmetrically arranged slots 13. The rear end of the rotating rod 5 is provided with a rotation slot. A clamping plate 14 is provided in the rotation slot via a rotation and torsion mechanism. The end of the clamping plate 14 is clamped in the clamping slot 13.

[0036] The rotation and torsion mechanism includes a cross bar 15, which is fixed in the rotation groove. The clamping plate 14 is rotatably sleeved on the outside of the cross bar 15. The rod wall of the cross bar 15 is sleeved with a torsion spring 16, and the two ends of the torsion spring 16 are fixedly connected to the cross bar 15 and the clamping plate 14 respectively.

[0037] After the standard test board 8 is rotated and replaced, it can be pulled by the card plate 14, so that one end of the card plate 14 rotates under the rotation support of the cross bar 15. At this time, the other end of the card plate 14 can be pulled out from the inside of the card slot 13, and then the rotating rod 5 can be rotated, so that the rotating rod 5 drives multiple standard test boards 8 to rotate and replace. When the standard test board 8 of the corresponding specification rotates to the bottom, the card plate 14 is released. Under the torsion recovery of the torsion spring 16, the card plate 14 can quickly rebound and continue to be inserted into the card slot 13, thereby completing the position fixation of the rotating rod 5 and the standard test board 8, ensuring the stable progress of subsequent testing work.

[0038] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
