DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1:

[0029] This embodiment provides an experimental device for detecting long-distance optical information loss, specifically Figure 1-Figure 5As shown, it includes an optical time domain reflectometer 5 and a support assembly 2 for carrying and adjusting the deflection angle of the optical time domain reflectometer 5; the support assembly 2 includes a carrying frame 204 for carrying the optical time domain reflectometer 5 and a set of slide rails 201 distributed on both sides of the carrying frame 204. The slide rails 201 are slidably connected to sliders 206. The slide rails 201 are rotatably connected to lead screws 202, which are threadedly connected to a slider 206. The carrying frame 204 is rotatably connected to the slider 206. The carrying frame 204 is rotatably connected to a support rod 203. The end of the support rod 203 away from the carrying frame 204 is rotatably connected to the slide rail 201. The lead screw 202 is transmission-connected to a knob 207.

[0030] The staff rotates the knob 207 to make the screw 202 rotate synchronously, and the screw 202 drives the slider 206 threadedly connected to it to slide on the slide rail 201. At this time, under the support of the support rod 203, the supporting frame 204 gradually begins to tilt from the horizontal state until the supporting frame 204 is in a vertical state; then with the continuous rotation of the knob 207, the supporting frame 204 begins to tilt in the opposite direction, so that the angle between the supporting frame 204 and the horizontal plane can be changed at will; the self-locking property of the thread between the screw 202 and the slider 206 is used to maintain the inclination angle of the supporting frame 204.

[0031] By providing the support assembly 2 , the problem of limited deflection angle options caused by the step-by-step change of the support angle when supporting the optical time domain reflectometer 5 in existing equipment is solved, and the optical time domain reflectometer 5 can be freely deflected and maintained.

[0032] Example 2:

[0033] This embodiment is further expanded on the basis of embodiment 1. Figure 8 As shown, it also includes a fastening assembly 3 for fixing the optical time domain reflectometer 5, and the fastening assembly 3 includes a plurality of fastening rods 301 slidably connected to the supporting frame 204, and a fastening spring 302 is provided between the fastening rods 301 and the supporting frame 204.

[0034] By providing the fastening assembly 3 , the optical time domain reflectometer 5 can be firmly fixed on the carrier frame 204 . In addition, the fastening assembly 3 can provide a buffer for the optical time domain reflectometer 5 when it is bumped, thereby reducing damage to the internal components of the optical time domain reflectometer 5 .

[0035] like Figure 9 As shown, it also includes multiple sets of anti-slip components 4 for fixing cables. The anti-slip components 4 include two symmetrically arranged clamping units 401, each of which is provided with a semicircular groove. The clamping units 401 are slidably connected to the carrier frame 204, and a clamping spring 403 is provided between the clamping units 401 and the carrier frame 204. The clamping units 401 are provided with a pull hole 402.

[0036] When the cable needs to be connected to the optical time domain reflectometer 5, the staff manually pulls open the two clamping units 401 in a set of anti-detachment components 4. At this time, the clamping spring 403 is squeezed. Then the cable is passed through the semicircular groove between the two clamping units 401 and inserted into the optical time domain reflectometer 5. Then the clamping unit 401 is released. The two clamping units 401 begin to clamp the cable under the action of the clamping spring 403, preventing the cable from accidentally detaching from the optical time domain reflectometer 5 when pulled, thereby improving the stability of the operation.

[0037] The pulling hole 402 is provided for fingers to pass through, thereby facilitating pulling of the clamping unit 401 .

[0038] like Figure 1-Figure 3 As shown, the device further includes a suitcase 1 for storing the optical time domain reflectometer 5 and the support assembly 2. The suitcase 1 includes a case shell 101, a cover plate 102 is slidably connected to the case shell 101, a handle 103 is rotatably connected to the case shell 101, and a plurality of anti-slip pads 105 are installed on the case shell 101. When the optical time domain reflectometer 5 is in the folded state, its display panel faces downward.

[0039] The suitcase 1 can be opened and closed by a sliding cover 102, and a handle 103 is provided for easy carrying; a plurality of anti-slip pads 105 are provided to increase the friction between the case shell 101 and the ground or table during use to prevent the suitcase 1 from sliding.

[0040] After the operator pulls the cover 102, they turn the knob 207. This causes the support frame 204 to tilt the optical time-domain reflectometer 5 from a horizontal position, with the display panel on the optical time-domain reflectometer 5 facing diagonally downward until the support frame 204 becomes vertical. Then, based on the operator's preferred viewing angle, the operator continues to turn the knob 207, causing the support frame 204 to tilt in the opposite direction, with the display panel on the optical time-domain reflectometer 5 now facing diagonally upward. Initially, the display panel of the optical time-domain reflectometer 5 faces downward to reduce dust from scattering on the display panel and function buttons, prevent accidental scratches on the display panel, and enhance protection for the optical time-domain reflectometer 5.

[0041] like Figure 6 、 Figure 7 As shown, the screw 202 is slidably connected to a knob 207 , a tension spring 205 is provided between the knob 207 and the screw 202 , and the box shell 101 is provided with an engaging groove 106 for engaging the knob 207 .

[0042] When the staff needs to rotate the knob 207, they first overcome the tension of the tension spring 205 to pull the knob 207 out of the fitting groove 106. After the rotation is completed, the knob 207 is embedded in the fitting groove 106 under the action of the tension spring 205. On the one hand, embedding the knob 207 in the fitting groove 106 can achieve a flat and beautiful effect on the exterior of the box shell 101 when the device is not in use. On the other hand, the knob 207 cannot be rotated after being embedded in the fitting groove 106, which can prevent the knob 207 from being accidentally touched, causing the deflection angle of the optical time domain reflectometer 5 to change and jitter, thereby further reducing factors affecting the accuracy of experimental data.

[0043] like Figure 2-Figure 3 As shown, a sealing ring 104 is provided on the box shell 101 , and the sealing ring 104 is made of rubber or plastic. When the optical time domain reflectometer 5 is in the retracted state, the edge of its display panel is in contact with the sealing ring 104 .

[0044] After the optical time domain reflectometer 5 is folded, the sealing ring 104 will fit the display panel, thereby preventing external dust and water stains from entering, and effectively protecting the display panel and function buttons.

[0045] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the scope of protection of the present invention.
