[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0023] The present application is based on the problem that the fiber modification method in the prior art is based on manual measurement by operators using a steel ruler, which has low efficiency and poor precision. The present application provides a mobile optical fiber cable length-fixing tool. In view of the drawbacks of the traditional fiber modification and length-fixing method, the application draws on the principle of a vernier caliper so that the optical fiber can slide along a slide to achieve length fixing, and graduations are set along the slide track to improve the length fixing accuracy.

[0024] Figure 1 A schematic diagram of the planar structure of a mobile optical fiber cable fixed-length tooling is shown; Figure 1 In the present invention, a mobile optical fiber cable fixed-length tooling comprises a track 110, on which is provided a straight slideway, in which a traction member 130 is slidably arranged, and on which a scale is arranged along the track of the straight slideway; the optical fiber is connected to the traction member 130, and the operator drives the traction member 130 to move along the track of the straight slideway, and can drag the optical fiber to move, while observing the scale to determine the current length of the optical fiber; a tail pressure block 120 penetrated by the optical fiber is also slidably arranged on the straight slideway of the track 110, and the tail pressure block 120 can cooperate with the traction member 130 to make the tension at every point on the optical fiber the same, and make the straight slideway parallel to the optical fiber; due to the traction of the traction member 130, in cooperation with the locking of the tail pressure block 120, the optical fiber can be forced to be straightened, that is, the tension at every point on the optical fiber is the same, thereby improving the accuracy of optical fiber measurement; in the present application, by setting a scale along the track of the straight slideway on the track 110, and using the tail pressure block 120 and the traction member 130 to force the optical fiber to be in a straightened state and parallel to the slideway The tracks are parallel, and the operator can directly observe the scale to determine the length of the optical fiber. This operation method reduces the experience requirements for the operator and improves the operation accuracy; the tail pressure block 120 and the traction member 130 are both matched with the linear slideway clearance, and the tail pressure block 120 and / or the traction member 130 can be driven by an external force to move along the linear slideway track, and after the external force is removed, the tail pressure block 120 and / or the traction member 130 maintain the state caused by the external force; for example, the tail pressure block 120 and the traction member 130 The size of is slightly larger than that of the linear slideway, and is squeezed and restricted in the slideway. Under normal circumstances, the tail pressure block 120 and the traction member 130 remain stationary due to the squeeze pressure, but when driven by an external force, they can still overcome the squeeze pressure and slide, that is, the slideway still allows the tail pressure block 120 and the traction member 130 to slide along their trajectory; alternatively, the tail pressure block 120 and the traction member 130 are connected to the linear slideway through a damping pad, so that the tail pressure block 120 and the traction member 130 can be stably docked after stopping.

[0025] Figure 2 A schematic structural diagram of the tail pressing block 120 is shown; Figure 2 In the embodiment, the tail pressing block 120 includes a base 121 and a pressing plate 122 rotatably disposed on the base 121; the pressing plate 122 is driven to rotate and open, and the optical fiber is placed between the base 121 and the pressing plate 122. At this time, relative movement can occur between the optical fiber and the tail pressing block 120, and the position of the optical fiber or the tail pressing block 120 can be adjusted. After the adjustment, the pressing plate 122 is driven to rotate in the opposite direction and close, and the pressing plate 122 and the base 121 are used to clamp the optical fiber, so that a lock is formed between the tail pressing block 120 and the optical fiber; in some other embodiments, the base 121 and the pressing plate 122 can also be slid open or bolted, and are not limited to rotational opening.

[0026] Figure 3 A schematic structural diagram of the traction member 130 is shown; Figure 4 The overall structural diagram of a mobile optical fiber cable fixed-length tooling is shown; Figure 5 Shows Figure 4 Schematic diagram of the state structure; Figure 3-Figure 5 In the embodiment, the traction member 130 has a core insert Boot card slot 131, and the core insert Boot card slot 131 has a socket for matching the optical fiber on the side facing the tail pressure block 120; the optical fiber is loaded into the clamping mouth, fixed by glue, and the traction member 130 is driven to move, so as to drive the optical fiber to move synchronously; the traction member 130 has a scale arranged along the linear slide track, and the scale spacing on the track 110 is at least 10 times the scale spacing on the traction member 130; the operator can roughly estimate the current length through the scale on the track 110, first move the traction member 130 to the approximate range, and then use the scale on the traction member 130 to fine-tune the position of the traction member 130 to ensure the accuracy of the optical fiber measurement; for example Figure 4 and Figure 5 As shown; it should be noted that, in the present application, the scale spacing on the track 110 is 10 mm, and the scale spacing on the traction member 130 is 0.1 mm, and the two have a scale ratio of 100 times; two groups of spaced-apart limit bars 132 protrude from the upper surface of the traction member 130, and the two groups of limit bars 132 are distributed on both sides of the optical fiber; the two limit bars 132 are distributed on both sides of the optical fiber, which can preliminarily limit the extension direction of the optical fiber to avoid optical fiber deviation.
