Embodiment
With reference to Figure of description, optical patchcord stationary installation of the present utility model is described in detail below.
As Fig. 1, Fig. 2, shown in Fig. 3, optical patchcord stationary installation of the present utility model, its structure comprises casing 1, described casing 1 is the cavity of all the other face closures of leading flank opening, case lid 2 is hinged with in casing 1 open side, the inner chamber of described casing 1 is provided with the first winding post 3, bumper post 4 and the second winding post 5, the first described winding post 3, bumper post 4 is connected with the sidewalls orthogonal of casing 1 inner chamber respectively with one end of the second winding post 5, in the first winding post 3, the free end of bumper post 4 and the second winding post 5 is respectively equipped with a jack, jack activity is plugged with falling prevention bracket 8, the bottom wall of inner cavity of described casing 1 is provided with wire jumper import 6 and wire jumper outlet 7.
In wire jumper import 6, place is provided with fixed pulley 10, is connected bottom described fixed pulley 10 by spring 11 with casing 1 diapire; Described spring 11 one end is connected with the support of fixed pulley 10, and the other end is connected with the holder of casing diapire.
As shown in Figure 4, described falling prevention bracket is made up of plate body 81, joint pin 82 and slip-off preventing bar 83, and described plate body 81 is circular, is vertically connected with joint pin 82 in the side of plate body 81, described joint pin 82 coordinates with jack, and the edge of described plate body 81 is evenly provided with multiple slip-off preventing bar 83.
