Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber equipment, and in particular relates to a free cover of a fiber distribution box. Background Art

[0002] The fiber splitter box houses optical components for fiber broadband, such as optical splitters and pigtails. The box protects these components. Currently, the box consists of a body and a door. The left side of the body and door are connected by a hinge, while the right side has a lock and fastener.

[0003] However, during routine broadband installation and maintenance, the door swings to the left to open, placing all the force of gravity on the left hinge. Because the horizontal direction of the door and latch is perpendicular to the direction of gravity, it's easy for the door and latch to misalign, or for the hinge to twist and deform, causing the splitter door to become stuck or fall off. This exposes optical components inside the box, such as the optical splitter and pigtails, reducing their service life. The resulting weak light path affects user perception and compromises aesthetics.

[0004] The protective covers currently available on the market use a matching cover body to achieve protection, but the existing protective cover body uses multiple sheet structures that are clamped on the fiber distribution box. Not only is the fixing strength insufficient, but it is also difficult to install and easily deformed. At the same time, the metal material increases the risk of electric shock, is heavy, and is prone to falling from high altitudes. Summary of the Invention

[0005] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a free cover for a fiber splitter box, which solves the problem that the lack of a cover on the box exposes the optical devices in the box, resulting in weak light in the optical path that affects the user's perception and reduces the service life of the optical devices. It also solves the problems of insufficient fixing strength of the fixture, difficulty in installation, easy deformation, increased risk of electric shock due to metal material, heavy weight, and easy falling from high altitudes.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A free cover for a fiber distribution box comprises a cover body (1), a holder (2) and a hinge (3), and is characterized in that a fixing ear (1-2) for matching with the optical fiber box is provided on the side of the cover body (1); a handle (1-1) is provided at the bottom end of the cover body (1); a buckle (1-3) is provided on the handle (1-1); both sides of the holder (2) are bent structures (2-1), and a corner structure (2-2) is fixed to the side of the bent structure (2-1) and one side of the holder (2); and the cover body (1) and the holder (2) are connected by a hinge (3).

[0008] The upper end of the bending structure (2-1) is provided with a through hole A (2-3), both ends of the fixer (2) are provided with through holes B (2-4), and the middle of the fixer (2) is provided with a through hole C (2-5).

[0009] The cover body (1) and the fixer (2) are rotatably connected via a hinge (3) and are detachable.

[0010] The dimensions of the cover (1) and the holder (2) match the dimensions of the optical fiber box.

[0011] The hinge (3) is connected by a connecting ear A (3-1) on the cover body (1) and a connecting ear B (3-2) on the fixer (2) via a rotating shaft.

[0012] The rotating shaft in the hinge (3) may be a rotating shaft with damping.

[0013] The cover (1) and the fixer (2) are made of non-metallic materials.

[0014] The through hole A (2-3), through hole B (2-4) and through hole C (2-5) are fixed to the optical fiber box by screws or clips.

[0015] A sealing ring may be provided on the inner side of the cover body (1).

[0016] When screws or clips are installed in the through holes A (2-3) and through holes B (2-4), the screws or clips penetrate into the grooves formed by the ribs provided at the two corners of the cover body (1) and the cover body (1).

[0017] When applied to an iron box, the cover (1) can be closed by magnetic attraction.

[0018] The beneficial effects of this novel method are:

[0019] When the device is fixed on the optical fiber box, the angle design of the holder greatly increases the strength of the holder, making the installation more secure. After being fixed with screws or clips, it is not easy to fall off when the cover is opened, and the holder is not easy to deform. The handle on the cover is provided with a buckle, which makes the cover and the optical fiber box closer and not easy to open. During maintenance, the handle can easily open the buckle, which is easy to install and operate. There is no need to replace the box, which avoids the user's use of the terminal during maintenance, reducing the cost of box replacement and the cost of manual maintenance.
