[0034] The following is combined with Figure 1—5 further describes this application in detail.

[0035] The embodiment of the present application discloses an optical fiber detection device.

[0036] Example 1

[0037] Reference Figure 1-3 A fiber optic detection device includes a detection component 1. The detection component 1 includes a reflector body 101 for detecting an optical fiber. An operation panel 102 and a detection port 103 are installed on one side of the reflector body 101. The operation panel 102 is located on the side wall of the reflector body 101. The detection port 103 is located at the upper end of the reflector body 101. By inserting the optical fiber into the port of the detection port 103, the reflector body 101 is used to detect the attenuation and damage position of the optical fiber. The structure and principle of the reflector body 101 are both existing technologies and are not repeated here. A support component 2 for supporting is installed on the reflector body 101;

[0038] The support assembly 2 is mounted to the rear side wall of the reflector body 101. The support assembly 2 includes a cover plate 201 hinged to the rear side wall of the reflector body 101. Two mounting grooves are also drilled on the cover plate 201 for easy use of the control assembly 4. The two mounting grooves are symmetrically arranged and drilled at the upper end of the cover plate 201. An adjustment opening 202 is drilled on the cover plate 201. The length of the adjustment opening 202 is controlled so that when the cover plate 201 is completely closed, the cover plate 201 will not contact the adjustment assembly 3. A fixing rod 203 is fixedly connected inside the adjustment opening 202. A rotating sleeve 204 is rotatably connected to the fixing rod 203 by being sleeved on the fixing rod 203. An adjustment assembly 3 for adjusting the angle between the cover plate 201 and the reflector body 101 is arranged on the rotating sleeve 204, and the adjustment assembly 3 is arranged between the cover plate 201 and the reflector body 101.

[0039] The adjustment component 3 includes two fixed plates 301 fixedly connected to the rear side wall of the reflectometer body 101, a rotating block 302 is rotatably connected between the two fixed plates 301 through a bearing, the interior of the rotating block 302 is set as a hollow structure, the lower side wall of the rotating block 302 is connected and fixed with a gas cylinder 303, the interior of the gas cylinder 303 is slidably connected with a piston 304, a push rod 305 is fixedly connected between the piston 304 and the rotating sleeve 204 by welding, and a connecting pipe 306 is connected and fixed on the rotating block 302, wherein the gas cylinder 303, the rotating block 302 and the connecting pipe 306 are all filled with inert gas, and a control component 4 for controlling the length of the adjustment component 3 is set at the end of the connecting pipe 306 away from the rotating block 302.

[0040] A protection component 5 for protecting the detection port 103 is disposed on the cover plate 201 , and a symmetrically disposed elastic pull rope 6 is fixedly connected between the cover plate 201 and the reflectometer body 101 .

[0041] Through the above arrangement, when the piston 304 moves downward, the push rod 305 and the rotating sleeve 204 can push the fixing rod 203, thereby pushing the cover plate 201 to flip downward. At this time, the detection port 103 is opened, which is convenient for the staff to quickly detect the optical fiber. At the same time, the cover plate 201 is used to effectively support the reflectometer body 101, so that the staff can operate the reflectometer body 101. The movement of the piston 304 requires the control component 4 to adjust the inert gas transmitted by the connecting pipe 306. When the control component 4 is no longer connected to the connecting pipe 306, the piston 304 cannot move. At this time, the angle between the reflectometer body 101 and the cover plate 201 can be fixed.

[0042] Reference Figure 4 The control assembly 4 includes a control cylinder 401 fixedly connected to the upper side wall of the reflectometer body 101 by bolts, a connecting pipe 306 penetrates the side wall of the reflectometer body 101 and is connected to the lower end of the control cylinder 401 and fixedly connected, a movable plug 402 is slidably connected inside the control cylinder 401, and the control cylinder 401 is filled with inert gas, and a vertical rod 403 arranged through the movable plug 402 is rotatably connected to the movable plug 402. A rotating shaft seal is installed between the movable plug 402 and the vertical rod 403, which is not shown in the figure. The rotating shaft seal can prevent the inert gas inside the control cylinder 401 from rotating when the vertical rod 403 rotates relative to the movable plug 402. In case of leakage, the upper end of the vertical rod 403 is fixedly connected to the disc 404 by bolts, the inner wall of the lower end of the control cylinder 401 is fixedly connected to the valve cylinder 405, the inner wall inside the valve cylinder 405 is rotatably connected to the valve core 406 by means of a sliding groove clamping, an L-shaped hole 407 connected to the port of the connecting pipe 306 is drilled inside the valve core 406, an exhaust hole corresponding to the port at the other end of the L-shaped hole 407 is drilled on the valve cylinder 405, the upper end of the valve core 406 is fixedly connected to the square rod 408 plugged into the lower end of the vertical rod 403, and the disc 404 is fixedly connected to the arrow sticker 409 set in the same direction as the lateral port of the L-shaped hole 407.

[0043] With the above arrangement, the staff only needs to press the disc 404 so that the disc 404 drives the movable plug 402 to move downward, so that the movable plug 402 transmits the air inside the control cylinder 401 to the fixed plate 301 and the inside of the air cylinder 303 through the L-shaped hole 407 and the connecting pipe 306, so that the air pushes the piston 304 to move, and the cover plate 201 can be opened. When it is necessary to fix the angle between the reflectometer body 101 and the cover plate 201, the staff only needs to rotate the disc 404 so that the disc 404 drives the square rod 408 to rotate through the vertical rod 403, and the square rod 408 drives the valve core 406 to rotate, so that the L-shaped hole 407 of the valve core 406 no longer corresponds to the exhaust hole of the valve cylinder 405, and the gas is sealed to achieve the fixation of the length of the adjustment component 3, thereby completing the angle fixation between the reflectometer body 101 and the cover plate 201.

[0044] See also Figure 5 The protective component 5 includes two symmetrically arranged dustproof pads 501 fixedly connected to the cover plate 201 by bonding. A water test paper 502 is sewn between the center of the dustproof pad 501 and the cover plate 201 by needle and thread. The water test paper 502 is a moisture detection test paper produced by Wuxi Lierjie Biotechnology Co., Ltd., which can change color after contacting water to serve as a reminder. The structure and principle of the water test paper 502 are all existing technologies and are not repeated here. A notch is cut on the cover plate 201, and a glass piece 503 is arranged on the notch.

[0045] Through the above arrangement, when the cover 201 is closed, the dustproof pad 501 covers the detection port 103, effectively blocking dust from entering the detection port 103; when the cover 201 contacts a large amount of water, the water will penetrate into the vicinity of the detection port 103, thereby causing the water test paper 502 to change color, reminding the staff to clean the water around the detection port 103, thereby avoiding water entering the detection port 103 and causing damage to the equipment, thereby further improving the protection of the detection port 103.

[0046] The implementation principle of an optical fiber detection device in the embodiment of the present application is as follows: when in use, first, the staff member places the reflectometer body 101 on the ground at an angle, and the angle of inclination can be placed according to actual needs. Then the staff member presses the disc 404, and the disc 404 drives the movable plug 402 to move downward, so that the movable plug 402 transmits the air inside the control cylinder 401 through the L-shaped hole 407 and the connecting pipe 306 to the fixed plate 301 and the air cylinder 303, so that the air pushes the piston 304 to move, and the piston 304 pushes the cover plate 201 through the push rod 305 to make it flip downward. When the cover plate 201 contacts the ground, the staff member rotates the disc 404, and the disc 404 drives the square rod 408 to rotate through the vertical rod 403, and the square rod 408 drives the valve core 406 to rotate, so that the L-shaped hole 407 of the valve core 406 no longer corresponds to the exhaust hole of the valve cylinder 405, thereby completing the angle fixation between the reflectometer body 101 and the cover plate 201. The state of the reflectometer body 101 after being supported is as shown in FIG. Figure 1 As shown, at this time, the staff quickly inspects the optical fiber;

[0047] When the cover plate 201 needs to be stored, the staff only needs to observe the arrow sticker 409 and rotate the disc 404 to make the L-shaped hole 407 on the valve core 406 correspond to the exhaust hole on the valve cylinder 405. At this time, the cover plate 201 is reset under the tension of the elastic pull rope 6. When the protective component 5 in the cover plate 201 contacts the detection port 103, the staff rotates the disc 404 again to complete the storage and fixation of the cover plate 201.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
