Description
Technical field
The utility model relates to a kind of LED display, particularly display screen box body.
Background technology
In prior art, along with more and more higher to the requirement of energy-conserving and environment-protective, and the maturing of LED display technique, the mainstream technology that LED display must will become large-scale area display, LED display mainly by LED unit module group assembling on metal framework casing, again by the LED control system of specialty, whole LED is made to demonstrate exquisite picture.And due to the feature of LED display own, so for display screen box body, waterproof, heat radiation ensure one of LED display unit casing safety, normal important performance run, and the realization of at present LED display casing waterproof, heat radiation be by driving into, air outlet and install scavenger fan additional to realize, and waterproof is needed into and out of air port, the outer cover of a box dress is usually increased outward at inlet and outlet.But the waterproof effect depending merely on an outer cover is undesirable, and except waterproof is with except heat radiation, be in communication with the outside owing to importing and exporting, outside dust easily enters in casing, causes damage to circuit component.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of more excellent display screen box body inlet and outlet structure.
The solution that the utility model solves its technical matters is: a kind of inlet and outlet structure of LED display casing, comprises cover plate, and described cover plate is provided with air inlet and air outlet, and described air inlet is provided with fan cassette holder, and described air outlet is provided with filter screen seat; Described fan cassette holder comprises pedestal and flap, and described pedestal is roughly in wedge shape, and the front end of pedestal is lower than rear end, and described pedestal is fixedly connected with cover plate, and the rear end of described flap and pedestal is hinged; Described filter screen seat comprises pedestal and filter screen compressing tablet, described filter screen compressing tablet and pedestal hinged.
As the further improvement of technique scheme, the surface of described pedestal and the surface of pedestal all have multiple air vent.
As the further improvement of technique scheme, described flap is provided with fan base, and described fan base is wedge shape, and the front end of fan base is higher than rear end.
As the further improvement of technique scheme, the front end of described flap is provided with screw hole, and the front end of described filter screen compressing tablet is also provided with screw hole.
As the further improvement of technique scheme, the inner side of described flap is provided with filter screen groove.
The beneficial effects of the utility model are: the utility model, by adding fan cassette holder and filter screen seat on inlet and outlet, all increases filter screen when then using, ensure that the humidity in casing and dustless degree in fan cassette holder and filter screen seat; Further, it is all very easily that the filter screen of fan cassette holder and filter screen seat is installed, and because flap and filter screen compressing tablet are all hinged, only need open flap and filter screen compressing tablet and replaceable filter screen when filter screen changed by needs time, saving replacing construction.The utility model is used for the dust-proof and waterproof of the inlet and outlet of LED display casing.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model, instead of whole embodiment, and those skilled in the art, under the prerequisite not paying creative work, can also obtain other design proposals and accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Embodiment
Be clearly and completely described below with reference to embodiment and the accompanying drawing technique effect to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.Obviously; described embodiment is a part of embodiment of the present utility model, instead of whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art obtains under the prerequisite not paying creative work, all belong to the scope of the utility model protection.In addition, all connection/annexations mentioned in literary composition, not singly refer to that component directly connects, and refer to and according to concrete performance, can connect auxiliary by adding or reducing, and form more excellent draw bail.Each technical characteristic in the invention, can combination of interactions under the prerequisite of not conflicting conflict.
With reference to Fig. 1, a kind of inlet and outlet structure of LED display casing, comprises cover plate 1, and described cover plate 1 is provided with air inlet and air outlet, and described air inlet is provided with fan cassette holder 2, and described air outlet is provided with filter screen seat 3; Described fan cassette holder 2 comprises pedestal 21 and flap 22, and described pedestal 21 is roughly in wedge shape, and the front end of pedestal 21 is lower than rear end, and described pedestal 21 is fixedly connected with cover plate 1, and described flap 22 is hinged with the rear end of pedestal 21; Described filter screen seat 3 comprises pedestal 31 and filter screen compressing tablet 32, and described filter screen compressing tablet 32 is hinged with pedestal 31.Time air inlet uses, put into by filter screen between flap and pedestal, then fixed by flap, filter screen can not be shifted, fixed form can be the mode etc. by screwing; Air outlet is also similar, is put into by filter screen between filter screen compressing tablet and pedestal, is then fixedly connected with pedestal by filter screen compressing tablet with screw.When filter screen changed by needs time, only need unclamp screw, then filter screen compressing tablet and flap and replaceable filter screen are opened in upset.
Be further used as preferred embodiment, the surface of described pedestal 21 and the surface of pedestal 31 all have multiple air vent.
Be further used as preferred embodiment, described flap 22 is provided with fan base 23, and described fan base 23 is in wedge shape, and the front end of fan base 23 is higher than rear end.Because flap is tilt when in use, so in order to ensure the parallel of fan, fan base is also arranged to wedge shape, and contrary with the gradient of pedestal, then and when can ensure that fan is arranged on fan base, axle center is vertical with cover plate, makes radiating effect more excellent.
Be further used as preferred embodiment, the front end of described flap 22 is provided with screw hole, and the front end of described filter screen compressing tablet 32 is also provided with screw hole.
