Optical fiber distribution frame (ODF) is used for termination and distribution of trunk optical cables at the central office in optical fiber communication system, which can conveniently realize the connection, distribution and scheduling of optical fiber lines. With the increasing degree of network integration, optical-digital hybrid distribution frame integrating ODF, DDF and power distribution unit has emerged, which is suitable for small and medium-sized wiring systems of fiber to community, fiber to building, remote module and wireless base station;

[0004] The above patent still has some problems when in use. When connecting optical fiber cables, traditional optical fiber distribution frames can only be installed at a single angle, and sometimes the optical fiber cables need to be forcibly bent, which makes the optical fiber cables easy to break. When one group of optical fiber cables is installed before the next group of optical fiber cables is installed, the previous group of optical fiber cables will hinder the staff from continuing to install, greatly reducing work efficiency. In addition, the existing optical fiber distribution frame cannot be rotated, resulting in the need for the staff to extend their bodies into the wiring cabinet for maintenance later. It is inconvenient to repair the optical fiber cables and cannot guarantee the personal safety of the staff. Therefore, we need to propose an optical fiber distribution frame with a rotating structure. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides: an optical fiber distribution frame with a rotating structure, such as Figure 1-4As shown, it includes a wiring frame 1 and two groups of wiring ports 10, both sides of the wiring frame 1 are fixedly connected with connecting columns 8, and the ends of the two groups of connecting columns 8 away from the wiring frame 1 are provided with rotating columns 7, and the outer arc surfaces of the two groups of rotating columns 7 are rotatably sleeved with connecting sleeves 2, and the outer arc surfaces of the two groups of connecting sleeves 2 are provided with moving grooves 4 corresponding to the connecting columns 8, and the front side of the wiring frame 1 is provided with a plurality of groups of rotating wiring components 6 for driving the wiring ports 10 to rotate;

[0025] Several groups of rotating wiring assemblies 6 all include a rotating column 7 and a rotating column 9. The rotating column 7 is bolted to the front side of the distribution frame 1. The rotating column 9 is rotatably arranged inside the rotating column 7, and two groups of wiring ports 10 are arranged on the front side of the rotating column 9. The rotating column 7 rotates inside the connecting sleeve 2 and drives the distribution frame 1 to rotate through the connecting column 8. When the distribution frame 1 is bolted to the inside of the box as a whole, it only takes a set of fixing bolts 5 on the mounting plate 3 to operate the distribution frame 1 to rotate, thereby facilitating the maintenance of the distribution frame 1 by the staff and avoiding the need for the staff to drill into the box for repairs.

[0026] The rotating wiring assembly 6 also includes an installation arc plate 12, an installation column 13, a limit head 18 and a limit module. The installation arc plate 12 is provided with three groups. The installation column 13 is fixedly connected to the inner arc surface of a group of installation arc plates 12. One end of the installation column 13 passes through the installation arc plate 12 and is fixedly connected to the limit head 18. The inner arc surface of the rotating column 7 is provided with a guide groove 19 corresponding to the limit head 18. The guide groove 19 is set in a U-shape. The limit head 18 moves inside the guide groove 19, driving the rotating column 9 as a whole to rotate back and forth at a certain angle, ensuring that the wiring port 10 rotates while avoiding the entanglement of the optical fiber line. When the optical fiber line needs to be connected at a certain angle, it only needs to rotate the wiring port 10, thereby avoiding the need to bend the optical fiber line.

[0027] The limiting module includes a limiting column 14, a connecting plate 15 and a positioning column 16. The positioning column 16 is rotatably set on the inner wall of the rotating column 7. The connecting plate 15 is fixedly connected to one end of the positioning column 16 away from the rotating column 7. There are two groups of limiting columns 14, and the two groups of limiting columns 14 are fixedly connected to the connecting plate 15. The two groups of limiting columns 14 are connected to the positioning column 16 through the connecting plate 15, thereby ensuring that the two groups of limiting columns 14 can rotate with the positioning column 16 as the center.

[0028] The mounting column 13 is located on the corresponding surface of the two groups of limiting columns 14, and the mounting column 13 does not contact the connecting plate 15. When the connecting column 8 moves along the guide groove 19, it drives the mounting column 13 to move. The mounting column 13 contacts the limiting column 14, and drives the limiting column 14 to rotate while limiting the limiting column 14. The entire rotating column 9 is confined inside the rotating column 7 by the connecting column 8 and the positioning column 16, so that the rotating column 9 can only expand and contract slightly inside the rotating column 7, and will not fall out of the rotating column 7 as a whole.

[0029] The inner walls of the other two sets of arc plates 12 are fixedly connected with arc-shaped wire troughs 17, and the two sets of arc plates 12 are connected to the corresponding wiring ports 10. The optical fiber cable passes through the wiring port 10 into the arc-shaped wire trough 17, thereby connecting the optical fiber cable to the inside of the distribution frame 1.

[0030] A rotating hole 20 corresponding to the positioning column 16 is opened inside the rotating column 7, and the positioning column 16 is rotatably engaged in the rotating hole 20. A larger cylinder is provided at one end of the positioning column 16, and the positioning column 16 is rotatably engaged in the rotating hole 20 as a whole through the cylinder to ensure the stability of the rotating column 9 during rotation, and the positioning column 16 does not contact the mounting arc plate 12, so as to avoid the positioning column 16 contacting the mounting arc plate 12 during rotation, causing the positioning column 16 to be unable to rotate.

[0031] An operating rod 11 is fixedly installed on the front side of the rotating column 9, and the operating rod 11 does not contact the wiring port 10. The staff drives the rotating column 9 to rotate and extend as a whole by moving the operating rod 11. The staff operates the operating rod 11 to drive the rotating column 9 to extend and retract slightly inside the rotating column 7 as a whole, thereby reducing the obstruction of the adjacent rotating column 9 to the staff and facilitating the staff to connect the adjacent wiring ports 10.

[0032] A mounting plate 3 is provided on the side of the two groups of connection sleeves 2 away from the distribution frame 1. Several groups of fixing bolts 5 are threaded through the side of the mounting plate 3. The entire device is bolted to the inside of the installation box through the mounting plate 3 and the fixing bolts 5.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
