Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber communication, in particular to an optical fiber distribution frame. Background Art

[0002] The optical fiber distribution frame is an optical fiber distribution device designed specifically for optical fiber communication computer rooms, and has functions of optical cable fixing and protection, optical cable termination, and wiring adjustment. It is an indispensable part in the information computer room.

[0003] For example, a pull-out type optical fiber distribution frame disclosed in CN202453558U includes a frame body and a wiring unit fixed on the frame body. The wiring unit includes an outer frame fixed on the frame body and a box body located inside the outer frame. The outer frame includes side plates on both sides, a rear side plate located at the rear, and cover plates and bottom plates above and below. The box body includes side plates on both sides and a front panel located at the front. The inner side of the side plate of the outer frame has a guide rail arranged parallel to the cover plate or the bottom plate. The outer sides of the side plates of the box body respectively have guiding parts matching with the guide rail. The guiding parts cooperate with the guide rail to enable the box body to move along the guide rail and extend out of the space enclosed by the outer frame.

[0004] Although the box body of the above pull-out type optical fiber distribution frame can be pulled out of the outer frame for the user to operate and repair the internal components of the box body, since the box body can only be pulled from one side of the outer frame to the outside of the outer frame, after the box body is pulled out, the operator can only construct outward from the side of the box body close to the outer frame, which limits the operation sequence of the operator, and is not flexible enough to use and not convenient enough for maintenance.

[0030] Figure 1 Shows the state when the second door panel 13 of the fiber optic distribution frame in this embodiment is closed, Figure 2 Shows the state when the first door panel 11 of the fiber optic distribution frame in this embodiment is opened. As Figure 1 And Figure 2As shown, the optical fiber distribution frame of this embodiment includes an outer box 1. One side of the outer box 1 is provided with a first door panel 11 that can be opened. When the first door panel 11 is opened, a first outlet 12 is formed. The side of the outer box 1 away from the first door panel 11 is provided with a second door panel 13 that can be opened. When the second door panel 13 is opened, a second outlet can be formed.

[0031] A guide rail 15 is provided on the inner wall of the outer box 1.

[0032] The first door panel 11 and the outer box 1 are hinged by a hinge 3, and the second door panel 13 and the outer box 1 are hinged by a hinge 3. This setting can facilitate the opening and closing of the first door panel 11 and the second door panel 13, and the first door panel 11 and the second door panel 13 will not separate from the outer box 1 when opened, making it more convenient to use.

[0033] The state when the second door panel 13 of the optical fiber distribution frame of this embodiment is opened is similar to Figure 2 and the state when the first door panel 11 is closed is similar to Figure 1 which is not shown in the accompanying drawings of the specification.

[0034] Figure 3 The state when the tray 2 is pulled out is shown. As Figure 3 shown, a tray 2 is slidably connected in the outer box 1, and the first outlet 12 and the second outlet of the outer box 1 can be used for the tray 2 to slide in and out of the outer box 1.

[0035] As Figure 4 shown, a guiding portion 21 adapted to the guide rail 15 is provided on the bottom of the tray 2. The guide rail 15 is provided on the inner wall of the outer box 1 near the bottom of the tray 2. The guiding portion 21 can cooperate with the guide rail 15 to facilitate the sliding of the tray 2. The guiding portion 21 is provided at the bottom of the tray 2 to make the force more uniform, the sliding more stable, and the service life longer.

[0036] As Figure 5 shown, a locking assembly that can be locked and cooperated with the outer box 1 is provided on the first door panel 11 and the second door panel 13. In this embodiment, the locking assembly includes a buckle 4 provided on the first door panel 11 and the second door panel 13, and a buckle groove 14 adapted to the buckle 4 is provided on the outer box 1.

[0037] The buckle 4 includes a main body 41 fixedly connected to the first door panel 11 and the second door panel 13, and a locking tongue 42 is slidably connected to the main body 41.

[0038] As Figure 7 shown, a buckle protrusion 421 is provided at the upper end of the locking tongue 42, and the buckle protrusion 421 is adapted to the buckle groove 14. A hand-pushing groove 422 is provided on the side of the locking tongue 42.

[0039] AsFigure 8 As shown, an anti-slip convex portion 424 is provided on the locking tongue 42, and a positioning post 423 is provided at the bottom.

[0040] As Figure 6 shown, a window 411 for exposing the hand-pushing groove 422 is provided on the main body 41, a positioning groove 412 is provided at the bottom of the main body 41, and an anti-slip clamping convex portion 413 adapted to the anti-slip convex portion 424 is further provided on the main body 41.

[0041] As Figure 9 shown, an elastic member 43 is provided between the locking tongue 42 and the main body 41 in the sliding direction of the locking tongue 42. The elastic member 43 in this embodiment is preferably a compression spring. The upper end of the compression spring is cooperatively positioned with the positioning post 423, and the lower end is cooperatively positioned with the positioning groove 412.

[0042] The upper end of the locking tongue 42 is exposed outside the main body 41. The snap protrusion 421 cooperates with the snap groove 14 to achieve the locking function of the snap 4 under the elastic action of the elastic member 43. The hand-pushing groove 422 provided on the locking tongue 42 is exposed through the window 411, facilitating an operator to press down the locking tongue 42 through the hand-pushing groove 422 to disengage the snap protrusion 421 from the snap groove 14 and release the locking function of the snap 4. The anti-slip convex portion 424 can cooperate with the anti-slip clamping convex portion 413 to prevent the locking tongue 42 from rising excessively under the elastic action of the elastic member 43, enabling the hand-pushing groove 422 to be perfectly exposed within the window 411 for convenient operation.

[0043] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept scope of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all fall within the protection scope of the present invention.
