Description

A kind of water-mist-proof LCDs of band EVA foam

Technical field

This utility model relates to water-mist-proof LCDs technical field, is specifically related to the water-mist-proof of a kind of band EVA foam LCDs.

Background technology

Outdoor advertisement machine is for indoor tv machine, and outdoor advertisement machine refers to carry out out of doors advertisement broadcasting A kind of LCD TV, it can run normally under sunlight the most out of doors, rainwater, information to be shown for enterprise be shown Out of doors, bringing good vision and hearing enjoying to outdoor audient, it is extensively applied to shopping centre, bus platform, public affairs Garden, square, community's Condom, tourist attractions, government and enterprises propagandist etc.！

Along with the application of outdoor advertisement machine is increasingly wider, the not enough exposed day by day that outdoor advertisement machine exists, such as liquid crystal display Screen brightness, definition deficiency, easily haze, coagulate the phenomenons such as water；It is known that due to outdoor life-time service, outdoor advertisement machine all has Safety glass plays protection crashproof, anti-riot.Safety glass hazes, solidifying water, directly affect most can perception, and be not easily cleaned, have for a long time Water smoke affects service life of a machine, therefore except own hardware needs constantly to promote, solves water-mist-proof problem particularly important.

Such as China Patent No. CN201520130306.9, date of declaration is disclosed in the patent of invention of on 07 08th, 2015 A kind of water-mist-proof TV display screen and television set based on water-mist-proof TV display screen, including being fixedly arranged on liquid crystal electricity Depending on the liquid crystal panel between glue frame one and LCD TV glue frame two and be located at liquid crystal panel leading portion and be fixedly arranged on LCD TV glue frame Toughened glass panel on two, LCD TV glue frame two is provided with adhered layer and porous material with the contact surface of toughened glass panel The bed of material, adhered layer surrounds " mouth " font with porous material layer is end to end.This utility model can play certain water-mist-proof effect Really, but the structure that its " mouth " character form structure is a kind of sealing, it is unfavorable for that cross-ventilation circulates, the formation effect to prevention water smoke The most limited, and this LCDs uses adhered layer to fix porous material layer to be not easy to change, due to adhered layer and many The service life of Porous materials layer is limited, and after reaching certain use cycle, its water-mist-proof effect also can substantially reduce, the most not Use in applicable advertisement machine out of doors.

Utility model content

(1) solve the technical problem that

For the disadvantages mentioned above existing for prior art, this utility model provides the water-mist-proof liquid crystal of a band EVA foam Display screen, it is possible to situation about easily forming mist efficiently against the display screen existing for prior art, be particularly suitable for application to open air Advertisement machine, and change EVA foam bar when facilitating LCDs periodic inspection, eliminate the use that EVA foam bar reaches certain The impact of poor effect after degree.

(2) technical scheme

For realizing object above, this utility model is achieved by the following technical programs:

A kind of water-mist-proof LCDs of band EVA foam, including liquid crystal module, glass film plates and EVA foam bar, described Liquid crystal module be provided above glass film plates, the upper surface of described liquid crystal module is provided with draw-in groove, the one of described draw-in groove End is fixed on the upper surface of described liquid crystal module, and the other end of described draw-in groove is provided with spring pressuring plate, described spring pressure Sheet is fixed on the upper surface of described liquid crystal module, and described EVA foam bar is arranged on described draw-in groove.

Further, described draw-in groove is set in parallel in the upper surface of described liquid crystal module, described draw-in groove about The centrage on the long limit of upper surface of described liquid crystal module is symmetrical.

Further, the width of the upper surface being smaller than described liquid crystal module of described draw-in groove.

Further, the length of described EVA foam bar is more than the length of described draw-in groove, and its thickness is more than described 2 times of card groove depth.

Further, the length of described EVA foam bar is less than the length of the upper surface of described liquid crystal module.

(3) beneficial effect

The technical scheme using this utility model to provide, compared with known publicly-owned technology, has the advantages that

1, this utility model can pass through to increase ventilative, low density EVA foam bar between liquid crystal module and face glass, Making the space between liquid crystal module and face glass form cross-ventilation circulation, the gas that during liquid crystal display screen work, temperature is high rises Discharging, outside air is supplemented by lower, effectively prevents the formation of water smoke.

2, this utility model is by arranging draw-in groove and spring pressuring plate, it is simple to install and change EVA foam bar, especially outdoor LCDs in advertisement machine, owing to outdoor advertisement machine is exposed in outdoor environment for a long time, and outside air humidity is relative Relatively big in indoor, so that often change EVA foam bar, this set changes EVA foam when facilitating outdoor advertising machine overhauling Bar reaches the effect of effective water-mist-proof.
