Description
Technical field
The utility model belongs to the demonstration product scope, is specifically related to a kind of demonstration product with explosion prevention function.
Background technology
At present, be used for the display of on-site supervision and televisor etc. and show product, there is following defective in its structure:
1, the existing radiating mode of product that shows is generally following several: offering louvre on the housing and in its housing fan is being set, perhaps offering heat dissipation channel in showing product, and on heat dissipation channel dust guard is set.
In the existing structure, extraneous air, inflammable gas, dust or water can freely enter the inside that shows product, make the waterproof and dustproof weak effect that shows product; Under the situation of specific use occasion, as the hazardous areas such as vapour station, refuelling station of liquefying, inflammable gas enters by louvre or hot channel and shows product inside, shows when product starts or is very easy in the operational process to produce electric spark, thereby cause the blast or the burning of inflammable gas; If but louvre is blocked, then be unfavorable for showing the heat radiation of product, show that the too high meeting of product internal temperature influence its operate as normal.
2, on the other hand, the existing display screen of product that shows generally is fixed on the fore shell, when mounted, need play screw from a side of fore shell is fixed on display screen on the fore shell, then display screen and back cover are fixed, this kind structure makes and has bigger gap between the front and rear casing that shows product, and dust or inflammable gas enter very easily easily and show product inside.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of high leakproofness that has is provided, and has the demonstration product of waterproof and dustproof and explosion-proof performance.
Its technical scheme is as follows:
A kind of demonstration product with explosion prevention function comprises housing, display screen and power panel, is provided with first opening and second opening on housing, is respectively equipped with first heating radiator and second heating radiator at first opening and second opening part; Aforementioned display screen and power panel place in the housing, and display screen, housing, first heating radiator and second heating radiator form closed cavity; The position of first heating radiator is corresponding with power panel and have the heat radiation gap between the two, and second heating radiator contacts with display screen.
For showing product, display screen and power panel are to produce two maximum parts of heat, in use, because second heating radiator directly contacts with display screen, the heat transferred that display screen produced is come out by second heat sink radiates to second heating radiator again, and the heat transferred of the secret generation of power panel is to first heating radiator, come out by first heat sink radiates again, effectively reduced the internal temperature that shows product; On the other hand, show that product is inner and extraneous relatively independent, extraneous air, inflammable gas, dust and water can't enter and show product inside, has improved the waterproof and dustproof and the explosion-proof performance that show product, is particularly useful for using at special occasions such as refuelling stations.
The technical scheme of the further refinement of aforementioned techniques scheme can be:
The inboard of described heating radiator is a substrate, and its outside is for being located at a plurality of heat radiator on the substrate.The heat of display screen and power panel is delivered to earlier on the substrate, distributes the radiating efficiency height again to the external world by heat radiator.
Front side at described back cover is provided with supporting spring, and described display screen is located on this supporting spring.When mounted, display screen is installed on the supporting spring of back cover, rather than is installed on the fore shell, after the installation, the gap between fore shell and the back cover is little, and extraneous dust and water are difficult for entering.
Between described housing and described first heating radiator, second heating radiator, be provided with seal.Be provided with after the seal, can further improve the sealing property that shows product.
The surface of described housing is provided with zinc coat, and the face of amounting to of described housing adopts the mode of no seam welding to connect.Adopt after this housing, show the intensity height of product, good airproof performance.
Described housing comprises fore shell, back cover and back shroud, and fore shell is connected with back cover and is provided with seal betwixt, and back shroud is connected on the back cover and also is provided with seal betwixt; Described display screen is located between fore shell and the back cover, and described second opening is located on the back cover, and described second heating radiator is located at second opening part and is exposed; Be provided with plate hole on back cover, described power panel is connected with display screen, and stretches in the back shroud after passing plate hole, and described first opening is located on the back shroud, and the described second diffusing device is located at second opening part and is exposed.
Front side at described display screen is provided with tempered glass, is equipped with anti-dazzle coating at the front side and the rear side of this tempered glass.The intensity height of tempered glass after its surface is provided with anti-dazzle coating, can reduce the reflective stimulation to human eye of glass as much as possible, and vision is more clear, and the observer can observe the shown image of display screen from wideer scope.
This demonstration product is provided with three plug connector of band earth terminal.Because this three plug connector has earth terminal, show that the static of product can discharge by earth terminal, avoid static on the demonstration product, to assemble, further raising shows security of products.
In sum, the utility model has the advantages that: when satisfying demonstration product heat dispersion, make the inside that shows product form a sealed space, extraneous air, inflammable gas, dust and water can't enter the inside that shows product, improved the waterproof and dustproof performance that shows product, good sealing effect, when special occasions used, security was higher.
