[0018] In order to make the purpose, technical scheme and advantages of the application more clear, the application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the application and do not limit the application.

[0019] Example 1:

[0020] Reference Figures 1 to 4 As shown in the figure, a kind of optical fiber tensile test device is disclosed, including base 1, the four corners of the base 1, four columns 2 are provided, and the top of two columns 2 adjacent to left and right ends is connected by fixed sleeve 3, the fixed sleeve 3 is fixedly connected with the column 2, sliding sleeve 4 is provided between two columns 2 adjacent to left and right ends, the two ends of the sliding sleeve 4 are respectively provided on adjacent columns 2, two fixed sleeves 3 and two sliding sleeves 4 are connected by mounting box 5, two mounting boxes 5 are provided with cable clamping member at the opposite ends, rotating lead screw 6 is provided between two columns 2 adjacent to left and right ends, the top of the rotating lead screw 6 is rotatably connected with the fixed sleeve 3, the sliding sleeve 4 is sleeved on the rotating lead screw 6, driving member is provided in the base 1, for driving two rotating lead screws 6 to rotate synchronously.

[0021] In the application, the optical fiber cable is clamped by two cable clamping members, and the rotating lead screw 6 is driven to rotate synchronously by the driving member, so as to drive the sliding sleeve 4 to move, and then the tensile test of the optical fiber cable is realized. The whole device has simple structure, and the optical fiber cable is stably clamped by the cable clamping member, so as to ensure that the optical fiber cable does not separate in the tensile test, and ensure that the experiment is carried out normally.

[0022] The cable clamping component includes a hydraulic telescopic column 7 disposed within the mounting box 5. A square outer shell 8 is connected to the mounting box 5. The outer shell 8 has a cavity, and a sliding block 9 is slidably disposed within the cavity. The hydraulic telescopic column 7 slides through the outer shell 8 and is connected to one end of the sliding block 9. The other end of the sliding block 9 is provided with a first cross groove 10. Each of the four openings of the first cross groove 10 is provided with a gripper. Each gripper includes a connecting end 11 rotatably disposed within the first cross groove 10. A clamping end 12 is hinged to the connecting end 11 away from the sliding block 9. The clamping end 12 is provided with multiple anti-slip textures 13 at the end away from the connecting end 11. Each clamping end 12 is provided with a through hole 14 and a limiting post 15 rotatably disposed through the through hole 14 on the side near the connecting end 11. The four limiting posts 15 are arranged in a grid pattern. A rotating hole 16 is provided on the outer shell 8 for connecting the limiting posts 15.

[0023] The square outer shell 8 is provided with a second cross groove 17 for the rotation of the clamping end 12.

[0024] The sliding block 9 is provided with mounting holes and four springs 18 at the four corners of the end away from the hydraulic telescopic column 7. A portion of each of the four springs 18 is vertically installed in the four mounting holes.

[0025] The hydraulic telescopic column 7 drives the sliding block 9 to slide within the cavity. Specifically, when the hydraulic telescopic column 7 extends, it drives the sliding block 9 to slide within the cavity. At this time, the hinge joint between the connecting end 11 and the clamping end 12 rotates, causing the four clamping ends 12 to move toward the end that is closer to each other. This allows the clamping end 12 to clamp the optical cable at the end away from the connecting end 11. At the same time, multiple anti-slip textures 13 are provided at the end of the clamping end 12 away from the connecting end 11. The anti-slip textures 13 further prevent the clamping end 12 from slipping on the optical cable, thus preventing the optical cable from detaching.

[0026] After the test is completed, the hydraulic telescopic column 7 retracts, causing the sliding block 9 to slide in the cavity. At this time, the hinge of the connecting end 11 and the clamping end 12 rotates, causing the four clamping ends 12 to move toward the ends that are far away from each other. This allows the clamping end 12 to detach from the optical cable at the end that is far away from the connecting end 11, making it easier for the cable to separate from the clamping end 12.

[0027] During the experiment, after the cable was clamped by the clamping end 12, the cable stuck to the clamping end 12. At this time, the spring 18 was set, and the compressed spring 18 pushed the sliding block 9 to slide, thereby accelerating the movement of the four clamping ends 12 toward the ends that are far away from each other, thus making it easier to take out the optical cable.

[0028] The limiting column 15 is arranged to limit the clamping end 12, that is, to ensure that the clamping end 12 rotates along the limiting column 15, and to ensure that the four clamping ends 12 move towards the end of mutual separation or mutual approach.

[0029] The driving member comprises a motor 19 arranged in connection with the inner wall of the base 1, the base 1 is internally provided with two fixed seats 20 arranged at intervals, the fixed seat 20 is provided with a first bearing 21, the lower end of the two rotating lead screws 6 is respectively arranged in the inner ring of the two first bearings 21, the first tooth disc 22 is arranged on the two rotating lead screws 6, the output end of the motor 19 is provided with a second tooth disc 23, the second tooth disc 23 and the two first tooth discs 22 are connected by the transmission of the belt 24.

[0030] The motor 19 drives the second tooth disc 23 to rotate, the second tooth disc 23 drives the two first tooth discs 22 to rotate through the belt 24, and the two first tooth discs 22 drive the two rotating lead screws 6 to rotate, respectively. In order to ensure that the two rotating lead screws 6 drive the sliding sleeve 4 to move synchronously, the thread screw directions of the two rotating lead screws 6 are arranged in opposite directions, thereby driving the mounting box 5 to move up and down, and completing the tension test of the optical cable.

[0031] Implementation column 2:

[0032] As shown in Figure 2 The inner wall of the base 1 is also provided with a mounting plate 25, the mounting plate 25 is fixedly provided with a connecting shaft 26, the top of the connecting shaft 26 is provided with a second bearing 27, the outer ring of the second bearing 27 is provided with a third tooth disc 28, the belt 24 is connected in transmission with the third tooth disc 28, and the third tooth disc 28 is arranged to adjust the tension of the belt 24.

[0033] Although the present application has been described herein with reference to the various illustrative embodiments, it is understood that various other modifications and implementations can be devised by those skilled in the art, which will fall within the principles and spirit of the disclosure. More specifically, many variations and modifications of the subject combination arrangement can be made to the constituent components and / or arrangements within the scope of the disclosure, drawings and claims.
