Description

Technical Field

[0001] This utility model relates to the technical field of optical fiber fusion splicer fixture structure, specifically a linkage opening and closing device for an optical fiber fusion splicer fixture. Background Technology

[0002] Fiber optic fusion splicers are mainly used for the construction and maintenance of optical cables in optical communication. The working principle is to use a high-voltage electric arc to melt the cross-sections of two optical fibers while using a high-precision motion mechanism to smoothly advance the two optical fibers into one, so as to achieve the coupling of the optical fiber mode field. Before fusion splicing, optical fiber clamps are needed to clamp the optical fibers.

[0003] In related technologies, fiber optic clamps and fiber optic fusion splicers are usually independent of each other. After the fusion splicer is opened, the components holding the fiber in the clamp need to be separated manually or by an external power source before the fiber can be placed in the clamp position. After splicing is completed, the clamping components need to be separated again to remove the fiber. This series of operations is cumbersome and inconvenient, reducing fiber optic splicing efficiency. For operators outdoors, the simpler the operation process, the higher the efficiency. Based on this, this application proposes a clamp linkage opening and closing device for a fiber optic fusion splicer. Utility Model Content

[0004] This invention provides a clamp linkage opening and closing device for a fiber optic fusion splicer, which solves the problem mentioned in the background art that the fiber optic clamp and the fiber optic fusion splicer are in an independent state, and the fiber can only be picked up and put in after the fusion splicer is opened, which is inconvenient to use and reduces the fiber optic splicing efficiency.

[0005] This utility model provides the following technical solution: a clamp linkage opening and closing device for a fiber optic fusion splicer, comprising a clamp body and a linkage structure. The clamp body includes a clamp base and a clamp cover movably connected to the clamp base. The linkage structure includes an active part connected to the windproof cover of the fiber optic fusion splicer and a driven block connected to the top center of the opening end of the clamp cover. The active part includes a fixed frame, one end of which is connected to the windproof cover of the fiber optic fusion splicer, and a rotating shaft movably connected to the center of the other end of the fixed frame. A hook is fixedly connected to the outer ring of the center of the rotating shaft, and the rotating shaft is connected to the fixed frame through a torsion spring.

[0006] Preferably, torsion springs are movably sleeved on the outer rings at both ends of the rotating shaft, with one end of the torsion spring fixedly connected to the rotating shaft and the other end of the torsion spring fixedly connected to the other end of the fixing frame.

[0007] Preferably, the sidewall of the driven block is provided with rounded corners, the driven block is inclined, the high end of the driven block is located outside the upper cover of the clamp, and the lower inclined surface of the driven block is provided with anti-slip texture.

[0008] Preferably, when the windproof cover of the fiber optic fusion splicer is closed, the end of the hook near the driven block is located directly below the driven block.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. The clamp linkage opening and closing device for this fiber optic fusion splicer utilizes a linkage structure to enable the clamp cover to open and close during the opening of the fusion splicer's windproof cover, thus achieving linkage opening and closing of the clamp cover. Through structural optimization, the operator's work efficiency is improved, while the operability of the fiber optic fusion splicer in outdoor environments is increased, the ease of use of the fusion splicer is enhanced, and the automation level of the fusion splicer is strengthened.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a clamp linkage opening and closing device for a fiber optic fusion splicer, including a clamp body and a linkage structure. The clamp body includes a clamp base 1 and a clamp cover 2 movably connected to the clamp base 1. In some embodiments of this application, a round rod is provided at one end of the clamp base 1, and the clamp cover 2 is fixedly connected to the round rod. Under the action of external force, the clamp cover 2 can perform circular motion with the round rod as the center, thereby realizing the opening and closing of the clamp cover 2.

[0023] The linkage structure includes an active part connected to the windproof cover of the fiber optic fusion splicer and a driven block 3 connected to the top center of the opening end of the clamp cover 2. The side wall of the driven block 3 is provided with rounded corners. The driven block 3 is inclined. The high end of the driven block 3 is located outside the clamp cover 2. The lower inclined surface of the driven block 3 is provided with anti-slip texture, and the upper inclined surface of the driven block 3 is a smooth plane.

[0024] The active unit includes a fixed frame 4. One end of the fixed frame 4 is connected to the windproof cover of the fiber optic fusion splicer. A rotating shaft 5 is movably connected to the middle of the other end of the fixed frame 4. A hook 7 is fixedly connected to the outer ring of the middle of the rotating shaft 5. Torsion springs 6 are movably sleeved on the outer rings of both ends of the rotating shaft 5. One end of the torsion spring 6 is fixedly connected to the rotating shaft 5, and the other end of the torsion spring 6 is fixedly connected to the other end of the fixed frame 4. The rotating shaft 5 is connected to the fixed frame 4 through the torsion springs 6. Due to the torsion springs, the hook 7 can move in a circular motion along the rotating shaft 5 under the action of external force. When the restriction on the hook 7 is released, the hook 7 can be reset under the action of the rebound force of the torsion spring 6, and the rebound force of the torsion spring 6 can offset part of the force applied to the hook 7.

[0025] When the fiber optic fusion splicer's windproof cover is closed, the end of hook 7 closest to driven block 3 is positioned directly below driven block 3. With this configuration, when the windproof cover is opened, it can move hook 7 via the fixing bracket 4. Because hook 7 and driven block 3 overlap, hook 7 can contact driven block 3 during movement, causing it to move. Driven block 3, driven by hook 7, rotates the clamp cover 2, opening it. When hook 7 separates from driven block 3... When the clamp cover 2 is open, the hook 7 returns to its original position under the restoring force of the torsion spring 6. During the closing process of the fiber optic fusion splicer's windproof cover, the windproof cover causes the hook 7 to move downwards. As the hook 7 moves downwards, it contacts the upper inclined surface of the driven block 3. The driven block 3 restricts the hook 7, and under this restricting force, the hook 7 rotates until it separates from the driven block 3. Under the restoring force of the torsion spring 6, the hook 7 returns to its original position, now located below the driven block 3. The upper surface of the hook 7 near the driven block 3 is a smooth plane, and the lower surface of the hook 7 near the driven block 3 has anti-slip textures.

[0026] In summary: When using the clamp linkage opening and closing device for this fiber optic fusion splicer, during the opening process of the fusion splicer, the hook 7 moves upward in a circular motion around the rotating shaft 8. Because the hook 7 and the driven block 3 have an overlapping surface, when the hook is lifted, the upper cover of the linkage clamp is lifted and opened, and the upper cover of the clamp moves in a circular motion around the circular rod 9. Figure 2 As shown. When the welding machine is turned off, hook 7 overlaps with driven block 3, causing obstruction as hook 7 moves downwards. When hook 7 contacts driven block 3, torsion spring 6 connecting hook 7 causes hook 7 to bend backwards until it moves downwards without obstruction. After hook 7 has completely passed driven block 3, torsion spring 6 causes hook 7 to open, returning to its initial state. The specific process is as follows: Figure 3 As shown.
