Description

TECHNICAL FIELD

[0001] The present application belongs to the field of optical fiber laying operation tools, and particularly relates to an optical fiber distribution frame operation tool. BACKGROUND

[0002] In the daily operation and maintenance of the optical fiber distribution frame, it is inevitable to perform the operation of covering and pulling out the dustproof cap for many times, and after a long operation time, the dustproof cap at the optical distribution flange is difficult to be inserted and pulled out due to aging and hardening, low temperature in winter, stiff hands of the operation and maintenance personnel and other reasons, and sometimes the dustproof cap beside is touched by mistake, which greatly affects the work efficiency.

[0003] Chinese invention CN112034561A discloses an FC optical fiber distribution frame dustproof cap extractor, which comprises a jaw, a first adjusting mechanism, an elastic reset mechanism, a second adjusting mechanism and a detection mechanism. One of the two jaws is provided with a groove, and the two jaws are rotatably installed through a first rotating shaft. First and second connecting rods are installed on the two jaws through the second adjusting mechanism. The first adjusting mechanism is connected to the jaw and comprises a shell, a first ratchet wheel, a second ratchet wheel and a pull rod. After the dustproof cap is grabbed by the two jaws, the closed locking structure formed by the first and second ratchet wheels realizes the closed locking of the two jaws, freeing the hands of the workers, so that the handle only needs to be held. In this way, the dustproof cap can be quickly pulled out, and the idle fiber core near the tail fiber being used will not be squeezed, ensuring the safety of the tail fiber being used.

[0004] However, the prior art lacks modular design, and if the grabbing block is damaged or needs to be adapted to different sizes of dustproof caps, the whole needs to be replaced or adjusted, and the flexibility is insufficient.

[0005] Secondly, although the grabbing block has a pressure sensor, it does not mention the design of the inner concave surface or the elastic material, and the grabbing force may be unevenly distributed.

[0006] In addition, the prior art lacks storage design, which may cause the tool to be scattered or the dustproof cap to be lost, especially during on-site operation.

[0007] Furthermore, the multi-mechanism design (ratchet wheel, pull rope, threaded rod) of the prior art may increase the operation complexity, especially in emergency or rapid operation. CONTENT OF THE UTILITY MODEL

[0015] Further, at least a part of the clamping head is made of elastic material.The clamping head can be directly made of elastic material or wrapped with an elastic sheath,

[0016] Further, the plug-in connector is provided with a longitudinal limiting protrusion, and the slot is provided with a limiting slot matched with the limiting protrusion.The relative rotation of the connecting plate and the mounting seat is prevented.

[0017] Further, the outer wall of the slot is provided with a fixed buckle, and the fixed buckle is arranged at the bottom end of the outer wall through a connecting seat with large top and small bottom.The buckle can prevent sliding, and the top of the connecting seat with large top and small bottom has stronger stress, which can prevent the connecting seat from breaking during installation or disassembly.

[0022] The clamping head adopts an inner concave surface design and partially uses silica gel or soft rubber (Shore A 20-40), and the clamping force is more evenly distributed, which effectively avoids scratching the dust cap or optical fiber compared with the existing technology of the grabbing block design, and is particularly suitable for fine operation of fiber distribution frame.

[0023] Through the intuitive connection mode of the plug and the fixing buckle, the installation and disassembly process is simplified, and compared with the existing technology of multi-mechanism design (ratchet, pull rope, threaded rod), the operation steps are reduced by more than 30%, which is suitable for scenes such as hand stiffness in winter or hardened dust caps.

[0024] Equipped with a special storage box (semi-closed collection tank + jack placement seat), the clamping device and the pulled dust cap can be arranged, avoiding scattered tools or lost accessories, and compared with the lack of storage design in the prior art, the on-site operation portability is improved.
