Abstract
The utility model discloses an explosion-proof industrial telephone, including a bottom shell and a surface shell assembled on the bottom shell in a sealing manner. The explosion-proof industrial telephone is characterized in that: an anti-explosive cavity formed between the bottom shell and the surface shell is provided with a PCB, a display screen and buttons are arranged between the surface shell and the PCB, an observation port matched with the display screen is disposed on a position on the surface shell corresponding to the display screen, the display screen is electrically connected with the PCB, the bottom of the bottom shell is recessed to form a battery compartment, a battery cover is used for packing a battery in the battery compartment and is fixed on the bottom shell by screws, and a waterproof rubber gasket is disposed on the edge position of the battery cover corresponding to the battery compartment. The explosion-proof industrial telephone has multiple sealing structures, is good in sealing performance, can effectively prevent combustible gases into the anti-explosive cavity of the cell phone housing, and prevent a circuit in the explosion-proof chamber producing sparks and further fire or explosion, being safe to use.
Description
[technical field]
The utility model relates to a kind of explosion-proof communication apparatus, particularly a kind of explosion-proof industrial phone.
[background technology]
To be material sharply become another kind of state and discharge the process of large energy from a kind of state through physics or chemical change in blast.Blast must possess three conditions: 1, explosive substance: can with the material of oxygen (air) reaction, comprise gas (such as hydrogen, acetylene, methane etc.), liquid (such as alcohol, gasoline etc.) and solid (such as dust, fibre dust etc.).2, oxygen, air.3, ignition source: comprise naked light, electric spark, mechanical spark, electrostatic spark, high temperature, chemical reaction, luminous energy etc.When explosive substance and airborne oxygen mix, when concentration is in the explosion limit scope, if there is ignition source, will blast.In inflammable and explosive place (such as the mining area, methane, coal-dust explosion mixture are arranged but in the environment of apodia with the corrosive gas that destroys metal and insulation and steam), the product that can become ignition source generally needs technological processing for explosion protection feature, not so can produce huge threat to people's lives and properties, and regular handset belongs to electric equipment, want in these inflammable and explosive places, to use, must do first technological processing for explosion protection feature.
