Description

Technical Field

[0001] This utility model is a wound anti-slip clamp for testing the tensile strength of optical fibers, belonging to the field of optical fiber testing technology. Background Technology

[0002] In optical fiber tensile strength testing, the stability of sample fixation and applied force directly affects the accuracy of test data. The core procedure is as follows: the end of the optical fiber is passed through corresponding holes on two posts, and then secured firmly by wrapping it several times around the post surface, utilizing the mutual holding force generated by the fiber's own winding to prevent slippage during testing. Subsequently, screws are used to restrict the relative position of the posts and the support carrier. By adjusting the distance between the two posts, the optical fiber is gradually subjected to axial tension. Finally, tensile strength data is collected, completing the testing process.

[0003] Screws used to limit the position of the posts typically have exposed threaded connections. The testing environment inevitably contains dust, fiber debris, metal powder, and other fine impurities. These impurities easily adhere to the screw threads and gaps through airflow and contact. As impurities accumulate, the meshing gap between the screw and the screw hole becomes filled, generating significant frictional resistance during tightening. This causes the spacing adjustment operation to become choppy and difficult. Furthermore, the spiral-shaped threads and narrow gaps make it difficult to completely remove the attached fine impurities through conventional wiping methods. The cleaning process requires the use of specialized tools to meticulously scrape away the residual impurities within the threads, which is time-consuming and labor-intensive, hindering the efficient conduct of fiber optic tensile strength testing.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a wound anti-slip clamp for testing the tensile strength of optical fibers, including a linear guide rail 1, on which two slide blocks 11 are fitted. Two sets of connecting plates 2 are respectively installed on the upper surfaces of the two slide blocks 11 by connecting screws 4. When the slide blocks 11 move along the linear guide rail 1, the distance between the two sets of connecting plates 2 changes, that is, the distance between the two sets of column rods 3 is adjusted synchronously, providing a basis for applying axial tension to the optical fiber.

[0017] See Figures 1-3 The connecting plate 2 has two parallel sides each equipped with a support plate 21. Two sets of columns 3 are provided, each set positioned on the upper side of one of the connecting plates 2. A shaft hole 26 is provided on the upper part of one side of each support plate 21. The end of the column 3 is slidably inserted into the shaft hole 26, completing the rotational connection between the column 3 and the support plate 21. A through hole 31 for inserting an optical fiber is provided in the middle of the outer surface of the column 3. Both ends of the column 3 are fitted with side plates 32 for connection and fixation. The through hole 31 on the column 3 is used to position the end of the optical fiber. After the optical fiber is wound several times around the surface of the column 3, it is firmly fixed by its own mutual pressure, preventing the optical fiber from slipping during testing.

[0018] See Figures 1-4A lug plate 52 is installed at one end of the horizontal cylinder 5. A circular opening 55 is opened at the upper part of one side of the lug plate 52. One end of the horizontal cylinder 5 is installed in the circular opening 55 to improve the stability of the connection between the horizontal cylinder 5 and the lug plate 52. The lower end of the lug plate 52 is installed at the upper end of the support plate 21. A middle plate 53 is installed in the middle of the horizontal cylinder 5. A screw hole is opened at the middle of one side of the middle plate 53. A long screw 51 is threaded into the screw hole. A gripping head is fixed to the end of the long screw 51 away from the side plate 32. The gripping head and the long screw 51 are integrally formed to facilitate the screwing of the long screw 51. Multiple positioning holes 33 are opened in a ring at equal intervals on one side edge of the side plate 32. One end of the long screw 51 extends into one of the positioning holes 33. Rubber discs 54 are provided on both sides of the middle plate 53 along the length of the long screw 51. The rubber discs 54 are sleeved on the long screw 51 and fixed to the long screw 51. The rubber discs 54 are slidably installed in the horizontal cylinder 5. The distance between the two rubber discs 54 is less than half the length of the horizontal cylinder 5. The threaded connection between the long screw 51 and the intermediate plate 53 is enclosed by the structure formed by the horizontal cylinder 5 and the two rubber plates 54, forming a closed space. This effectively blocks dust, fiber debris, metal powder and other small impurities in the test environment, preventing impurities from adhering to the thread lines and gaps. This solves the problem of thread jamming and increased turning resistance from the root, ensuring smooth spacing adjustment.

[0019] See Figures 1-4 A horizontal plate 22 is provided on the upper side of the connecting plate 2. Small holes are opened at both ends of the horizontal plate 22, and connecting screws 4 that are threaded to the slide block 11 are inserted into the small holes. A tension plate 23 is installed on one side of the horizontal plate 22, and the end of the tension plate 23 away from the horizontal plate 22 extends to one side of the connecting plate 2. The tension plate 23 has an L-shaped structure, and an opening 24 is opened on one side of the tension plate 23. A reinforcing rib 25 is installed between the vertical part and the horizontal part of the tension plate 23. The reinforcing rib 25 improves the stability of the tension plate 23 structure, and the design of the opening 24 facilitates the attachment of tension ropes to the tension plate 23. The connecting screws 4 are used to simultaneously limit the relative positions of the horizontal plate 22, the connecting plate 2, and the slide block 11, thereby reducing the number of connecting screws 4 used.
