[0029] The utility model is further described below in conjunction with the accompanying drawings:

[0030] like Figure 1 — Fig.10 As shown, an optical fiber distribution box includes an installation shell 101, an internal connector 102 is arranged in the installation shell 101, a plurality of threading tubes 104 are installed at the bottom of the installation shell 101, the optical fiber enters the installation shell 101 from the threading tube 104, and is connected to the internal connector 102 after winding, a winding mechanism is installed in the installation shell 101, a plurality of wire clamping mechanisms are arranged on the winding mechanism, an opening and closing mechanism is arranged on the installation shell 101, the winding mechanism includes a plurality of installation frames 201 wound around the internal connector 102, a slideway 202 is opened in the installation frame 201, one side of the installation frame 201 is connected to a No. 1 connecting shaft 204 by bolts, and one end of the No. 1 connecting shaft 204 is connected to the installation shell 101. It is rotatably connected with a fork-scissor lifting mechanism 205, and the wire-holding mechanism includes a moving block 301. The moving block 301 is detachably connected to the slideway 202 of the installation frame 201. A rotating column 303 is connected to one side of the moving block 301 by bolts, and the end of the rotating column 303 away from the moving block 301 is rotatably connected to the wire-holding frame 305. A plurality of wire-holding grooves 306 are arranged in the wire-holding frame 305. The strands of optical fibers are clamped into the wire-holding grooves 306 of the wire-holding frame 305, and a suitable number of them are set so that the moving block 301 is clamped on the installation frame 201 in a state parallel to the slideway 202, thereby realizing the fixing of the optical fibers, and arranging them evenly and regularly, which is convenient for the staff to install in the early stage and to repair and disassemble in the later stage.

[0031] In this embodiment, a wedge block 302 is glued to one side of the moving block 301, and a plug block 304 is sleeved on the side of the rotating column 303. The plug block 304 is conical. When the rotating column 303 is rotated, the moving block 301 is turned from the parallel slide 202 setting to the vertical slide 202 setting in the slide 202. During this process, the wedge block 302 will gradually tighten and pull the plug block 304 into the slide 202 to complete the position locking of the wire clamping mechanism.

[0032] In this embodiment, the opening and closing mechanism includes a closed door 401, a pulling belt 403 is bonded to the inner side of the closed door 401, a pull rod 404 is bonded to one end of the pulling belt 403, and a No. 2 connecting shaft 405 is connected to one end of the pull rod 404 by bolts. The fork shear lifting mechanism 205 includes a plurality of shafts and connecting rods. The bottom of the fork shear lifting mechanism 205 is rotatably connected to a mounting seat 206.

When the closed door 401 is opened, the closed door 401 pulls the pull rod 404 through the pulling belt 403, and the pull rod 404 drives the No. 2 connecting shaft 405 to move. The No. 2 connecting shaft 405 pulls up the fork shear lifting mechanism 205 to expand it, and the spacing between each installation frame 201 is increased, which is convenient for observing the arrangement of each optical fiber and facilitating positioning and disassembly.

[0033] In this embodiment, a guide block 203 is welded to the middle position of the installation frame 201, and a No. 2 guide rod 407 is slidably connected to the guide block 203. The No. 2 guide rod 407 is connected to the inner wall of the installation shell 101 by bolts. The end of the pull rod 404 away from the No. 2 connecting shaft 405 is slidably connected to the No. 1 guide rod 406, and the No. 1 guide rod 406 is connected to the inner wall of the installation shell 101 by bolts. The No. 1 guide rod 406 and the No. 2 guide rod 407 are arranged perpendicular to the installation shell 101, which is conducive to the installation frame 201 being vertically pulled out by the fork shear lifting mechanism 205.

[0034] In this embodiment, a lock buckle 103 is connected to one side of the mounting shell 101 by bolts, and a docking buckle 402 corresponding to the position of the lock buckle 103 is connected to one side of the closed door 401 by bolts. After the closed door 401 is closed, the lock buckle 103 and the docking buckle 402 are locked by a lock.

[0035] In this embodiment, a screw rod 408 is threadedly connected to the closed door 401 , and a pressing rod 409 is welded to one end of the screw rod 408 . The pressing rod 409 is used to press the guide block 203 .

[0036] Working principle: When the device is in use, the closed door 401 is opened. During the opening process, the closed door 401 drives the pull rod 404 to move through the pulling belt 403, and the pull rod 404 pulls the No. 2 connecting shaft 405, and the No. 2 connecting shaft 405 drives the fork shear lifting mechanism 205 to unfold. At this time, the intervals between multiple installation frames 201 become larger, which is convenient for installation work. Each optical fiber is passed through the inside and outside of the installation shell 101 through the threading tube 104, and then a suitable number of wire clamping mechanisms are used to strand the optical fibers and clamp them in the wire clamping groove 306 of the wire clamping frame 305. Each wire clamping frame 305 is spaced at a suitable distance, so that the moving block 301 is clamped on the installation frame 201 in a state parallel to the slideway 202. In this state, the moving block 301 can slide in the slideway 202. After each moving block 301 moves to a suitable position, the rotating column 303 is rotated, and the moving block 301 is arranged in the slideway 202 to turn vertically in the slideway 202. The straight slide 202 is set. During this process, the wedge block 302 will gradually tighten and pull the plug block 304 into the slide 202 to complete the position locking of the wire clamping mechanism, realize the fixing of the optical fiber, and arrange it evenly and regularly. After the installation is completed, the closed door 401 is closed. After the closed door 401 is closed, the screw 408 is inserted into the corresponding position on the closed door 401, and the pressure rod 409 extends into the second guide rod 407 to press the outermost guide block 203 downward, the fork shear lifting mechanism 205 is folded, and several installation frames 201 approach to one side. Then the screw 408 is screwed into the threaded position of the closed door 401 to lock the installation frame 201. When maintenance is needed, similarly, the screw 408 is first unscrewed and the closed door 401 is opened. When the closed door 401 is opened, the fork shear lifting mechanism 205 is unfolded, so that the spacing between several wire clamping mechanisms on the installation frame 201 becomes larger, which is convenient for staff to check and repair.
