Based on the above, when the wiring box 200 is installed in the wiring box, the bottom of the side edge thereof contacts the push rod 101b-2, pushing the sliding block 101b to slide inwards, and simultaneously the connecting rod 101d moves and hooks the sliding block 101b in cooperation with the third elastic member 101e, so that the sliding block 101b is fixed; the movable slot 101a-5 at the bottom of the sliding block 101b drives the fourth hinge post 101c-1, and since the fifth hinge post 101c-2 is fixed, the hook claw 101c rotates around the fifth hinge post 101c-2 to hook the limiting head 200a-4 at the bottom end of the wiring box 200 upwards. When the wiring box 200 is to be taken out, the wiring box 200 is pushed inward again, the link 101d slides, the third elastic member 101e pushes out the slider 101b, and the hook 101c is released, so that the wiring box 200 can be taken out.

The optical fiber is wound in the wiring box 200 through the winding unit 201, the mechanical structure design is adopted, the complicated power system control is not needed, after the optical fiber is wound for the first time, the optical fiber is not needed to be wound again, the optical fiber drawn out from the wiring box 200 can be automatically drawn back into the wiring box 200, one end of the cable is connected to the wiring terminal 202a and is fixed, even if the cable at the other end is drawn, the cable wound on the wiring disc 201a cannot be loosened, the whole device is lighter, and more cost is saved on the manufacturing and processing of the device; in order to facilitate the maintenance and replacement of workers, the invention adopts a structure which is convenient to assemble and disassemble, so that the steps of maintenance, replacement and the like are simpler, and because the installation is simple, the connection mode of the buckling unit 202 is difficult to avoid loosening, but the wiring end 202a is firmly fixed in a state that the internal cable is strained; when the optical fiber is damaged and needs to be replaced, only the two ends led out by the optical fiber need to be loosened, at the moment, the optical fiber can be collected into the box by the wire spool 201a, the wiring box 200 is opened, and the wire spool 201a can be directly taken out for replacement, so that the replacement is quick and convenient; when the number of the optical fibers is large, the optical fibers can be wound on different wire reels 201a respectively, and when the number of the optical fibers is small, the optical fibers can be wound among the wire reels 201a, so that the optical fibers are prevented from being curled too much and the service life of the optical fibers is shortened.

It is important to note that the construction and arrangement of the present application as shown in the various exemplary embodiments is illustrative only. Although only a few embodiments have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters (e.g., temperatures, pressures, etc.), mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter recited in this application. For example, elements shown as integrally formed may be constructed of multiple parts or elements, the position of elements may be reversed or otherwise varied, and the nature or number of discrete elements or positions may be altered or varied. Accordingly, all such modifications are intended to be included within the scope of this invention. The order or sequence of any process or method steps may be varied or re-sequenced according to alternative embodiments. In the claims, any means-plus-function clause is intended to cover the structures described herein as performing the recited function and not only structural equivalents but also equivalent structures. Other substitutions, modifications, changes and omissions may be made in the design, operating conditions and arrangement of the exemplary embodiments without departing from the scope of the present inventions. Therefore, the present invention is not limited to a particular embodiment, but extends to various modifications that nevertheless fall within the scope of the appended claims.

Moreover, in an effort to provide a concise description of the exemplary embodiments, all features of an actual implementation may not be described (i.e., those unrelated to the presently contemplated best mode of carrying out the invention, or those unrelated to enabling the invention).

It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure, without undue experimentation.

It should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
