Description
Technical field
The utility model relates to a kind of outdoor fiber cable cross connection box.
Background technology
At communication field, fiber cable cross connection box is a kind of common communication apparatus, it is generally used for holding all kinds of telecommunication apparatus, thereby and in running, will produce a large amount of heat owing to including many telecommunication apparatus in telecommunication distributing box, for the heat radiation of cross-connecting box, conventionally be all on casing, to offer some air intake vents and some air outlets, utilize simple thermal convection principle, allow air that the dissipation of heat of box house is gone out.If commuting case is in the damp and hot rainy environment in south, airborne humidity is very large, and the telecommunication apparatus of so easy corrosion and short circuit cross-connecting box inside, causes the life-span of telecommunication apparatus and the decline of transmission quality.Can cause heat radiation not smooth but telecommunication apparatus is put in the cross-connecting box of sealing, easily allow the temperature in the cross-connecting box of sealing exceed normal working temperature, telecommunication apparatus is caused to damage.
Summary of the invention
The utility model is for deficiency of the prior art, a kind of commuting case being applicable under wet environment is provided, can in the environment of rainy day, automatically close air intake vent and air outlet, prevent that moisture from entering in casing, solve in the past commuting case in moist environment, be easily the corroded problem of short circuit of internal component.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of commuting case being applicable under wet environment, comprise casing, on described casing, be provided with several air inlets and several air outlets, in described casing, be fixedly installed axle sleeve, on described axle sleeve, be provided with first back-up ring, on described axle sleeve, be movably set with pillar, on described pillar, be provided with second back-up ring, between described first back-up ring and described second back-up ring, be provided with spring, described pillar stretches out outside described casing and top is provided with feeder, described feeder top is provided with beveled, in described beveled, be provided with metal screen, described pillar lower end is provided with left follower lever and right follower lever, on described air inlet, be provided with first chute, on described air outlet, be provided with second chute, on described first chute, slide and be provided with the first baffle plate matching with described air inlet, on described second chute, be provided with the second baffle plate matching with described air outlet, on described first baffle plate, be provided with first connecting link, described first connecting link connects described left follower lever, on described second baffle plate, be provided with second connecting link, described second connecting link connects described right follower lever, on described air inlet, be provided with first blend stop, on described first blend stop, be provided with the first groove matching with described first baffle plate, in described first groove, be provided with rubber blanket, on described air outlet, be provided with second blend stop, on described second blend stop, be provided with the second groove matching with described second baffle plate, in described second groove, be also provided with rubber blanket.
In technique scheme, preferred, on described first baffle plate and described second baffle plate, be provided with elastic rubber strip.
In technique scheme, preferred, on described casing, be provided with the O-ring seal matching with described pillar.
In technique scheme, preferred, on described first chute, be provided with the first limited block matching with described first baffle plate, on described second chute, be provided with the second limited block matching with described second baffle plate.
Arrange like this, outstanding feature of the present utility model is provided with a feeder exactly at casing top, feeder connects the pillar that is positioned at casing, after pillar is under pressure, can slide and be positioned at first baffle plate and the second baffle plate on air inlet and air outlet, allow first baffle plate and second baffle plate block air inlet and air outlet, prevent that moisture from entering in casing.Its groundwork principle is with spring supporting between pillar and axle sleeve, generalized case carapax et plastruw testudinis baffle plate and second baffle plate do not shelter from air inlet and air outlet, once after raining, rainwater drops onto in feeder, feeder props up column pressure, make pillar downward, also allow first baffle plate and second baffle plate move, seal up air inlet and air outlet simultaneously.If after rain stops, air is still moist, and the water in feeder can rapid evaporation, still keeps certain gravity, and first baffle plate and second baffle plate still seal up air inlet and air outlet.If sunlight is fierce, moisture declines fast, and the water rapid evaporation gravity in feeder reduces, the stressed minimizing of pillar, and first baffle plate and second baffle plate set back, and no longer cover air inlet and air outlet, allow in casing and carry out circulation of air heat radiation by air inlet and air outlet.
Compared with prior art, the beneficial effects of the utility model are: can in the environment of rainy day, automatically close air intake vent and air outlet, prevent that moisture from entering in casing, solved in the past commuting case in moist environment, be easily the corroded problem of short circuit of internal component.
