Description
Technical Field
[0001] The utility model relates to the technical field of optical fiber production, in particular to an optical fiber tensile strength detection device used in optical fiber production. Background Art
[0002] Optical fiber is a thin, transparent fiber typically made of glass or plastic that transmits light signals. It propagates light signals along the fiber's interior through internal reflection, enabling high-speed data transmission and communications. Optical fiber boasts high bandwidth and low attenuation, making it widely used in telecommunications, the internet, and healthcare. Before production and use, optical fibers undergo tensile strength testing to ensure they meet performance standards. Tensile strength is a key performance indicator, ensuring they resist deformation or breakage during use.
[0003] Existing optical fiber tensile strength testing devices typically fix one end of the optical fiber and apply a tensile force to the other end via a force-applying device. However, these devices have several limitations: the tensile force of the force-applying device is fixed, making it difficult to adjust quickly and efficiently, and unable to adapt to the needs of optical fibers of different specifications. In addition, existing devices often lack the functions of automated force adjustment and precise control, resulting in low test efficiency and an inability to meet the demand for efficient and flexible testing in modern optical fiber production. Therefore, it is necessary to design an optical fiber tensile performance testing device for optical fiber production that can support optical fibers of various specifications and improve test efficiency and accuracy.

DETAILED DESCRIPTION
[0018] The following describes embodiments of the present invention with reference to the accompanying drawings.
[0019] Embodiment: A device for detecting the tensile strength of optical fiber used in optical fiber production, such as Figure 1-Figure 5As shown, it includes a base 1, a mounting plate 2, a vertical plate 201, a top plate 202, a first winding wheel 3, a cylinder 4, a connecting block 41, a first fixing block 5, a second winding wheel 6, a slide rod 7 and a first connecting spring 8. The top front side of the base 1 is provided with a mounting plate 2, the first winding wheel 3 is installed on the lower front side of the mounting plate 2, a vertical through hole is opened in the middle and upper part of the front of the mounting plate 2, the top rear side of the base 1 is provided with a cylinder 4, the rear side of the mounting plate 2 is symmetrically provided with vertical plates 201, a top plate 202 is provided between the upper parts of the two vertical plates 201, and the cylinder 4 is provided with a first fixed block 5 at the top, and rectangular through holes are opened on the vertical plates 201. A connecting block 41 is slidably provided between the rectangular through holes on the two vertical plates 201. A circular hole is opened in the middle of the connecting block 41, and the telescopic rod of the cylinder 4 passes through the circular hole of the connecting block 41. Two sliding rods 7 are symmetrically provided at the bottom of the first fixed block 5. The sliding rod 7 passes through the connecting block 41. The bottom of the sliding rod 7 contacts the upper surface of the base 1. The two sliding rods 7 are both covered with a first connecting spring 8. The bottom end of the first connecting spring 8 is against the bottom of the sliding rod 7, and the top end of the first connecting spring 8 is against At the bottom of the connecting block 41, a second winding reel 6 is fixed on the front side of the connecting block 41 through a vertical through-hole. When people perform optical fiber tensile performance testing, one end of the optical fiber is fixed to the first winding reel 3 on the mounting plate 2. Because the mounting plate 2 is made of 7075 series aluminum alloy, which is close to high-strength steel in strength, the mounting plate 2 is light in overall weight while ensuring strength. The other end of the optical fiber is fixed to the second winding reel 6. The first winding reel 3 and the second winding reel 6 are both hollow cylindrical in shape, which is conducive to the winding of the optical fiber and reduces its own weight. As the cylinder 4 works, the telescopic rod of the cylinder 4 drives the first fixed block 5 to move upward, thereby the two sliding rods 7 also move upward. During the movement, the first connecting spring 8 is compressed. When the first connecting spring 8 is compressed to a certain extent, the first connecting spring 8 is no longer compressed, but drives the connecting block 41 to move upward, thereby driving the second winding reel 6 to move upward. By controlling the upward movement distance of the telescopic rod of the cylinder 4, the upward movement distance of the second winding reel 6 is controlled, thereby realizing the detection of different tensile strengths of optical fibers.
[0020] like Figure 3 and Figure 5As shown, it also includes a side plate 203, a bearing seat 91, a first screw rod 9, a clamping block 10, a pulley 11, a connecting belt 12, a rocker 13 and a scale 14. The side surface of the mounting plate 2 is symmetrically provided with side plates 203 on the left and right sides. The two vertical plates 201 are located between the two side plates 203. The upper part of the rear side wall of the mounting plate 2 is symmetrically provided with bearing seats 91. The bearing seats 91 are located between the adjacent side plates 203 and the vertical plates 201. The first screw rod 9 is provided on the bearing seat 91. The lower end of the first screw rod 9 is screwed with a clamping block 10. The two side walls of the clamping block 10 are fitted with the vertical plate 201 and the side wall of the side plate 203. The upper ends of the two first screw rods 9 are provided with pulleys 11. The two pulleys 11 are rotatably connected by a connecting belt 12. The right pulley 11 is provided with a rocker 13. The upper parts of the sides of the two side plates 203 away from each other are provided with scales 14. When the connecting block 41 moves upward to a certain height, the connecting block 41 will not continue to move upward but will be supported by the blocking block 10. The specific distance between the second winding wheel 6 and the first winding wheel 3 can be read through the scale 14 provided on the side plate 203. When the tensile strength measurement is to be increased, the second winding wheel 6 needs to continue to move upward, which requires the blocking block 10 to move upward as well. The pulley 11 is driven by manually rotating the rocker 13, and then the two first screws 9 are driven to rotate. The size of the blocking block 10 is slightly smaller than the width between the adjacent side plates 203 and the vertical plate 201, so the two blocking blocks 10 will move upward along the first screw 9. When the blocking block 10 moves upward to the set scale, the rocker 13 is stopped. The L-shaped rocker 13 is designed to save effort and is rotated by gripping the top of the rocker 13, which conforms to the normal movements of the human hand and makes it easy for people to rotate the pulley 11.
[0021] like Figure 2 and Figure 4 As shown, a second fixing block 15, a third fixing block 16 and a second screw 17 are also included. The second fixing block 15 is provided at the bottom of the first winding wheel 3 and the top of the second winding wheel 6. The second fixing block 15 slides with the third fixing block 16, and the second screw 17 passes through the third fixing block 16 and is screwed with the second fixing block 15. When people conduct optical fiber tensile performance testing, it is extremely inconvenient to directly fix the two ends of the optical fiber on the first winding wheel 3 and the second winding wheel 6. One end of the optical fiber is wound on the second fixing block 15 on the first winding wheel 3, and then the second screw 17 is tightened to fix it. Then, the optical fiber is wound on the first winding wheel 3 and the second winding wheel 6 in sequence, and then the other end of the optical fiber is fixed on the second fixing block 15 on the second winding wheel 6, and also fixed by tightening the second screw 17.
[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
