Description

Technical Field

[0001] The utility model belongs to the technical field of measuring tools, and in particular relates to an optical fiber sheath measuring tool. Background Art

[0002] Fiber optic sheathing is a major downstream application of PBT materials. Fiber optic sheathing materials processed from PBT offer both mechanical strength and flexibility, along with low thermal shrinkage, making them ideal for this application. Currently, PBT fiber optic sheathing materials have been processed into a variety of grades, all of which offer stable performance and a long service life.

[0003] The market is now overflowing with PBT brands, processing, and production suppliers, each with varying material properties. In response, China has developed its own fiber optic jacket material testing standards, referencing the performance indicators of relevant international industries. However, due to differences in testing equipment, test conditions, and data analysis, and even some vendors failing to provide clear testing and evaluation methods for unspecified test items, material testing results can vary significantly, resulting in a lack of unified evaluation standards.

[0004] Currently, the testing performance of optical fiber sheath mechanical properties is unstable. During some optical fiber sheath testing, the clamping of the fixture causes partial surface damage, and the fracture is always near the clamping edge. This phenomenon is particularly obvious for optical fiber sheaths with a diameter of less than 2.5mm. This patent addresses this problem by designing a set of optical fiber sheath fixing devices to reduce the fluctuation problem in optical fiber sheath testing and improve the accuracy of optical fiber sheath testing.

[0022] 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.

[0023] refer to Figure 1 As shown, the utility model provides an optical fiber sheath measuring tool, comprising: an equipment body for measuring the optical fiber sheath, a stretching position is provided in the equipment body, two clamping mechanisms are symmetrically provided from top to bottom in the stretching position, a stretching mechanism for stretching is provided between the two clamping mechanisms, each clamping mechanism includes a mounting frame and a rotating shaft 16 that can rotate on the mounting frame, based on the rotation, one end of the optical fiber sheath is wound around the rotating shaft 16, and a measuring area for measurement is formed between the two rotating shafts 16.

[0024] As described above, when using the device body, two clamping mechanisms and stretching mechanism provided by the present invention, the end of the optical fiber sheath is placed on the rotating shaft 16. When the rotating shaft 16 is rotated, the optical fiber sheath can be rotated and wound around the rotating shaft 16 and fixed. The stretching mechanism can drive the two rotating shafts 16 to move to opposite sides, thereby straightening the optical fiber sheath, thereby facilitating the measurement of the optical fiber sheath.

[0025] In this utility model, combined with Figure 4 As shown, in this embodiment, an inclined hole 10 for accommodating the end of the optical fiber sheath is formed on the side wall of each rotating shaft 16, and the inclined hole 10 is inclined at an angle of 30-50 degrees to the radial direction of the rotating shaft 16.

[0026] As described above, when using the inclined hole 10 provided by the present invention, when it is necessary to test the sample, the optical fiber sheath is inserted into the inclined hole 10 of the rotating shaft 16 respectively, and when the rotating shaft 16 is shaken to a fixed position, the optical fiber sheath is fixed with tape or a soft pressure block. After that, the relevant performance of the sample can be measured. During the test, the optical fiber sheath is required to wrap around the outer circumference of the rotating shaft 16 at least 3 times to ensure that the rotating shaft 16 does not affect the mechanical properties of the optical fiber during the test.

[0027] In this utility model, combined with Figure 1-2 As shown, the mounting frame of this embodiment includes a horizontal plate 9 and two mounting plates 7 symmetrically installed at both ends of the horizontal plate 9. A rotation groove 4 is passed through the two mounting plates 7. The two ends of the rotating shaft 16 are respectively rotatably installed in the two rotating grooves 4. A rocker 8 for driving the rotating shaft 16 to rotate is provided on the outer side of one of the mounting plates 7.

[0028] Combine Figure 1-3 As shown, one of the mounting plates 7 is further provided with a limiting mechanism for limiting the rotation of the rotating shaft 16 , and the limiting mechanism is arranged at one end of the rotating shaft 16 away from the rocker 8 .

[0029] Combine Figure 2-3 As shown, the limiting mechanism includes a gear 15 and a latch 12. The gear 15 is arranged at the rotation axis of one end of the rotating shaft 16. A mounting seat 13 is welded on the outer wall of the mounting plate 7. The latch 12 is movably installed on the mounting seat 13, and one end of the latch 12 can be inserted into the teeth of the gear 15. A fastening bolt 14 is screwed to the outside of the mounting seat 13, and one end of the fastening bolt 14 abuts against the latch 12.

[0030] As described above, when using the mounting bracket provided by the present invention, a mounting position for the rotating shaft 16 can be provided on the horizontal plate 9 through the two mounting plates 7, and the rotating shaft 16 can be rotatably installed between the two mounting plates 7 through the rotating groove 4. When the end of the optical fiber sheath is wound around the rotating shaft 16, one end of the pin 12 is inserted into the tooth, and the fastening bolt 14 is tightened to fix the position of the pin 12. At this time, the gear 15 cannot rotate, thereby preventing the rotating shaft 16 from rotating, thereby preventing the end of the optical fiber sheath from detaching from the rotating shaft 16. The rotating shaft 16 can be driven by the rocker 8 to rotate and adjust, thereby facilitating the winding of the optical fiber sheath around the rotating shaft 16.

[0031] In this utility model, combined with Figure 3 As shown, the device body of this embodiment includes a frame 1 and two docking poles 11. The two docking poles 11 are installed in the longitudinal direction of the frame 1 from top to bottom. The stretching mechanism is installed between the frame 1 and one of the docking poles 11. A connecting mechanism for connection is provided between the two horizontal plates 9 and the two docking poles 11.

[0032] Combine Figure 2As shown, the connection mechanism includes a docking sleeve 6, one end of which is welded to the side of the horizontal plate 9 away from the rotating shaft 16, and each docking sleeve 6 is provided with a docking hole 17 for accommodating the insertion of the docking column 11, and each docking sleeve 6 is provided with a mounting hole 18 passing through the docking column 11 on the side wall, and a connecting bolt 5 connecting the docking sleeve 6 and the docking column 11 is provided in the mounting hole 18.

[0033] As mentioned above, when using the device body provided by the present invention, the frame 1 in the device body provides an installation position for the two docking columns 11, and the cross plate 9 is detachably installed on the docking column 11 through the docking sleeve 6 and the connecting bolt 5, so that the two rotating shafts 16 are sequentially set in the stretching position. After removing the connecting bolt 5, the cross plate 9 can be removed from the docking column 11, which is convenient for inspection and maintenance of the mounting frame, the rotating shaft 16 and the limiting mechanism.

[0034] In this utility model, combined with Figure 1 As shown, the stretching mechanism of this embodiment includes an electric push rod 3, a tension sensor 19 and a lifting plate 2. The electric push rod 3 is longitudinally installed on the frame 1, and the tension sensor 19, the lifting plate 2 and one of the docking columns 11 are sequentially installed on the telescopic end of the electric push rod 3.

[0035] As mentioned above, when using the stretching mechanism provided by the present invention, when the electric push rod 3 in the stretching mechanism is started, it drives the lifting plate 2 to be raised and lowered in the frame 1, thereby driving one of the docking posts 11 to move closer to or away from the other docking post 11, so as to facilitate the stretching and straightening of the fixed optical fiber sheath. During this process, the degree of force on the optical fiber sheath can be detected by the tension sensor 19, and when the tension reaches the threshold, the drive of the electric push rod 3 is stopped. The tension sensor 19 is directly connected to the external display, and data monitoring and data adjustment are performed through the display. The display is not drawn in the figure, which is convenient for later measurement of the optical fiber sheath. The electric push rod 3 can be replaced by a variety of devices, such as hydraulic cylinders and other linearly driven devices.
