In the description of the present application, it should be noted that, for the terms of orientation, such as "central", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., it indicates that the orientation and positional relationship shown in the drawings are based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be construed as limiting the specific scope of protection of the present application.

It is noted that the terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

Embodiment as shown in fig. 1 to 4, a rotary optical fiber distribution frame comprises an upper cover plate 1 and a frame body 2 which are mutually covered, and also comprises a hanging lug 6, wherein the section of the hanging lug 6 is U-shaped, and the frame body 2 is rotatably connected with the upper wall and the lower wall of the hanging lug 6 through the front end of one side wall. When the optical fiber distribution frame is installed, the hanging lug 6 firstly passes through the mounting hole 601 on the side wall of the hanging lug 6 through a bolt, and is fixedly installed on the side wall of a distribution box (not shown), and then the frame body 2 is rotatably connected with the hanging lug 6 through a rotating piece.

Simultaneously, the lateral wall is all installed to the left and right sides and the rear side of support body 2, installs distribution box 4 in the inside position detachable that is close to the outside of support body 2, installs a plurality of adapters 5 on the distribution box 4, and the concrete quantity of adapter 5 can set up according to the needs of reality. The inside of support body 2 is close to inboard position and still fixed mounting has melting fiber dish 3, melts and is connected through the optic fibre line that corresponds with adapter 5 quantity between fiber dish 3 and the adapter 5. When needs change the line or maintain adapter 5, can rotate support body 2 round the articulated position of hangers 6 earlier, until support body 2 is located the distribution case outside, then take out distribution box 4 along the inside of support body 2, very sufficient that this moment will become adapter 5's operating space to conveniently change the line or maintain.

In order to prevent the optical fiber from being pulled when the distribution box 4 is pulled out of the frame body 2, a length of the optical fiber between the distribution box 4 and the fiber melting plate 3 is reserved in advance; these reserved optical fiber lines are easily twisted when the wiring box 4 is located in the rack body 2. Therefore, as shown in fig. 2, a winding slot 301 may be provided on the side wall of the fiber melting disc 3, and when the distribution box 4 is located in the frame body 2, the reserved optical fiber lines are arranged and wound in the winding slot 301; when the wiring box 4 is pulled out of the frame body 2, the reserved optical fiber wound in the winding groove 301 is released and pulled out.

Specifically, as shown in fig. 1, the distribution box 4 includes a base plate 41 and a mounting plate 42 fixedly connected to each other, the mounting plate 42 is located on a side of the base plate 41 close to the fusible fiber tray 3, and the adapters 5 are sequentially fixedly mounted on the mounting plate 42. When adapter 5 need change the line or when maintaining, pulling distribution box 4 slides until breaking away from support body 2 through bottom plate 41 along support body 2 lateral wall, in order to improve distribution box 4 in support body 2 internal connection stability, can carry out damping sliding connection with bottom plate 41 and support body 2 lateral wall.

Meanwhile, the distribution box 4 further comprises a nameplate 43, and the nameplate 43 is hinged with one side of the bottom plate 41 far away from the fiber melting plate 3. The inscription plate 43 is also provided with reference numerals of a plurality of types, for example, as shown in fig. 1, the reference numerals being arabic numerals. The sequence of the labels corresponds to the position of the adapter 5, so that the worker can conveniently and quickly identify the position of the adapter 5 needing to be changed or repaired.

In order to prevent the nameplate 43 from interfering with the threading or maintenance of the adapter 5, as shown in fig. 1 and 3. Support plates 44 are fixedly mounted on both ends of the base plate 41, and limit holes 441 are formed in the support plates 44. Meanwhile, the two ends of the nameplate 43 are also fixedly provided with limit plugs 431, and the limit wipers 431 are generally made of soft materials such as rubber. When the wiring box 4 is positioned in the frame body 2, the limiting plug 431 is matched with the limiting hole 441, and the nameplate 43 is in a vertical state; when the cable is required to be changed or repaired, the limiting plug 431 can be pulled out of the limiting hole 441, and then the nameplate 43 can be rotated around the hinged position, so that a larger operation space is provided for the cable changing or the repair.

Since a plurality of subscribers use one optical fiber distribution frame at the same time, many optical fiber lines are connected to the output ends of the adapters 5, and the optical fiber lines can be routed out neatly as shown in fig. 1 and 4. A gap exists between the mounting plate 42 and the nameplate 43 in the wiring box 4, and the optical fiber wires connected with the output ends of the adapters 5 are all placed in the gap; meanwhile, the concave space of the hanging lug 6 is a wire arranging groove 602, and the optical fiber wires of the user are connected with the output end of the adapter 5 through the communication between the wire arranging groove 602 and the gap, so that the outgoing and arrangement of the optical fiber wires are facilitated.

Specifically, in order to facilitate the detachment and installation of the upper cover plate 1, as shown in fig. 1, a connecting plate 21 is fixed at the upper end of the left and right side walls of the frame body 2, and a clamping groove 211 is arranged on the connecting plate 21; a fixing plate 22 is fixed to the upper end of the rear side wall of the frame body 2, and a screw 7 hole is formed in the fixing plate 22. Meanwhile, the two sides of the upper cover plate 1 are provided with the buckles 101, and the rear side of the upper cover plate 1 is also provided with the screw 7 holes. When needing upper cover plate 1 and support body 2 lid fashionable, earlier buckle 101 and draw-in groove 211 cooperation, then carry out fixed connection through screw 7 hole with upper cover plate 1 and bottom plate 41 through screw 7, make things convenient for upper cover plate 1's dismantlement and installation through the fixed quantity that reduces screw 7.

The foregoing has described the general principles, essential features, and advantages of the application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, which are merely illustrative of the principles of the application, but that various changes and modifications may be made without departing from the spirit and scope of the application, and these changes and modifications are intended to be within the scope of the application as claimed.
