Summary of the invention

The purpose of this utility model is the defect that exists for above-mentioned prior art, proposes a kind of rotary optical fiber distributing unit case.

The technical solution adopted in the utility model is, design a kind of rotary optical fiber distributing unit case, comprise casing and be arranged on the interior optical fiber thermoconnecting tray of this casing, wherein, optical fiber thermoconnecting tray front console upward and downward turns down outward, and in both sides, being respectively equipped with screw, optical fiber thermoconnecting tray and casing, by Stud connection, make optical fiber thermoconnecting tray rotate and to shift out around this double-screw bolt.

In one embodiment, described base plate and/or top board are provided with spaced apart a plurality of projection.

The base plate of described casing and header board, by gemel connection, install the limited location baffle plate near hinge position on base plate.

Described optical fiber thermoconnecting tray panel is provided with a handle.

Be positioned at optical fiber thermoconnecting tray off-position place on described base plate and be provided with fixed magnet.

Compared with prior art, the utility model adopts optical fiber thermoconnecting tray to open in the mode of a left side or right rotation, can independently select according to demand optical cable turnover mode, the use of fusion joining disk is more stable, can not cause because open angle is excessive optical fiber to damage after rotary-tray is opened, both facilitate molten fibre, can guarantee again the radius-of-curvature of optical fiber, in narrow and small work space, can utilize fully environment to reach working efficiency.

Embodiment

Below in conjunction with drawings and Examples, utility model is described in detail.

As shown in Figure 1, the rotary optical fiber distributing unit case that the utility model proposes, comprise by header board 9, left plate 3, right plate 4, base plate 6, backboard 7 and top board 5 and enclose the casing that forms and be arranged on optical fiber thermoconnecting tray in this casing, wherein, optical fiber thermoconnecting tray front console 26 upward and downwards turn down outward, and in both sides, be respectively equipped with screw, and described optical fiber thermoconnecting tray comprises screw and nut with casing by double-screw bolt 12() be connected.

As can be seen from Figures 2 and 3, be provided with optical cable fixation kit 11 near backboard 7 places on the left plate 3 of casing, right plate 4, by set screws component 15, be fixed on left plate 3, right plate 4, can overlap insulation cover pad assembly 17 is arranged between screw and optical cable fixation kit 11.Be provided with optical cable near an end of header board 9 on left plate 3, right plate 4 and enter hole and cross coil 10, the periphery that optical cable enters hole and crosses coil 10 can be equipped with dentation and protect lines, for the protection of optical cable.Optical cable enters hole in the incoming light ray fusion joining disk from this, then by crossing coil 10, picks out casing.Be provided with some binding bridges in casing, be used for the optical cable top solid in fusion joining disk.

Can find out from Fig. 2, Fig. 3, optical fiber thermoconnecting tray comprises front console 26, and optical fiber thermoconnecting tray front console 26 upward and downwards turn down outward, and in both sides, are respectively equipped with screw, described optical fiber thermoconnecting tray is connected by double-screw bolt 12(and comprises screw and nut with top board 5, the base plate 6 of casing, or rivet) connect.Be positioned at the pallet 21 of bottom, comprise a rectangular part and a trapezoidal portions.Two sidewalls with the optical cable entrance 22, sidewall 22 rear portions slope inwardly, and the angle of inclination is that optical fiber thermoconnecting tray can rotate and get final product around link.

Can be provided with postive stop baffle 27 near the hinge position on base plate, after pallet 21 Unscrews, postive stop baffle 27 is used for preventing that the anglec of rotation of pallet 21 is excessive, affects the radius-of-curvature of optical fiber.

Base plate 6 and top board 5 punchings have a plurality of isolated projections 25, can find out from Fig. 1, Fig. 3, projection 25 is shaped as truncated cone-shaped, make optical fiber thermoconnecting tray make somebody a mere figurehead in the optical fiber distributing unit case, avoided when taking off the rotating shaft of an end, optical fiber thermoconnecting tray tilts to cause other end rotating shaft stress deformation and this end face of optical fiber thermoconnecting tray and Cell collision, has improved the stability of product.
