Description
Technical field
The present invention relates to a kind of outdoor fiber cable cross connection box.
Background technology
In communication field, fiber cable cross connection box is a kind of common communication apparatus, is commonly used for accommodating all kinds of telecommunication apparatus,
And due to including the telecommunication apparatus of many in telecommunication distributing box so as to substantial amounts of heat will be produced in running, for cross-connecting box
Radiating, be generally all that some air intake vents and some air outlets are opened up on casing, using simple thermal convection principle, allow air to make
The heat of box house is distributed.If commuting case is in the damp and hot rainy environment in south, the humidity in air is very big,
Telecommunication apparatus so easily inside corrosion and short-circuit cross-connecting box, under causing life-span and the transmission quality of telecommunication apparatus
Drop.But telecommunication apparatus is put into the cross-connecting box of sealing and can then cause that radiating is not smooth, the temperature easily allowed in the cross-connecting box of sealing
Beyond normal operating temperature, telecommunication apparatus is caused to damage.
The content of the invention
The present invention is directed to deficiency of the prior art, there is provided a kind of moistureproof commuting case, can be in the environment of rainy day certainly
It is dynamic to close air intake vent and air outlet, prevent moisture from entering in casing, solve conventional commuting case and be in moist environment, it is internal
Component be easily corroded short circuit problem.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：A kind of moistureproof commuting case, bag
Casing is included, several air inlets and several air outlets are provided with described casing, axle is fixedly installed in described casing
Set, is provided with first back-up ring on described axle sleeve, pillar is movably set with described axle sleeve, and second gear is provided with described pillar
Circle, is provided with spring between described first back-up ring and described second back-up ring, described pillar is stretched out outside described casing and top
Collecting tank is provided with, described collecting tank top is provided with beveled, metal screen, institute are provided with described beveled
The lower rod end stated is provided with left follower lever and right follower lever, and first chute, described air outlet are provided with described air inlet
On be provided with second chute, slided on described first chute and be provided with the first baffle plate that is engaged with the air inlet, described second is slided
The second baffle plate being engaged with the air outlet is provided with groove, first connecting rod is provided with described first baffle plate, described first connects
The described left follower lever of extension bar connection, is provided with second connecting rod on described second baffle plate, described second connecting rod connects described
Right follower lever.
In above-mentioned technical proposal, it is preferred that be provided with elastic rubber strip on described first baffle plate and described second baffle plate.
In above-mentioned technical proposal, it is preferred that the sealing ring being engaged with the pillar is provided with described casing.
In above-mentioned technical proposal, it is preferred that the first limit being engaged with described first baffle plate is provided with described first chute
Position block, is provided with the second limited block being engaged with described second baffle plate on described second chute.
So set, outstanding feature of the invention is exactly in casing top there is provided a collecting tank, collecting tank connection position
In the pillar in casing, pillar can be slidably disposed in first baffle plate and second baffle plate on air inlet and air outlet after being under pressure, allow
First baffle plate and second baffle plate block air inlet and air outlet, prevent moisture from entering into casing.Its main operational principle be pillar with
Spring supporting is used between axle sleeve, generally first baffle plate and second baffle plate do not shelter from air inlet and air outlet, after raining,
Rainwater is dropped onto in collecting tank, and collecting tank gives strut pressure so that pillar is downward, while also allowing first baffle plate and second baffle plate to move
It is dynamic, seal up air inlet and air outlet.If after rain stops, air is still moist, then the water in collecting tank will not rapid evaporation, according to
Certain gravity, first baffle plate and second baffle plate is so kept still to seal up air inlet and air outlet.If sunlight is fierce, moisture declines
Block, the then water rapid evaporation gravity reduction in collecting tank, pillar stress is reduced, and first baffle plate and second baffle plate set back, no longer hide
Air port and air outlet are lived in, allow in casing carries out air circulation radiating by air inlet and air outlet.
Compared with prior art, the beneficial effects of the invention are as follows：Can be automatically switched off in the environment of rainy day air intake vent and
Air outlet, prevents moisture from entering in casing, solves conventional commuting case and is in moist environment, and internal component is easily rotten
Lose the problem of short circuit.
