Abstract
The utility model provides an explosion isolation type light emitting diode (LED) display screen, which comprises an explosion isolation case and an LED electronic display screen, wherein the LED electronic display screen is embedded in the explosion case and is fixed through fastening screws. Thereby, even when the LED electronic display screen generates sparks caused by static electricity in work, the explosion ignition of Inflammable substances and gas around the explosion isolation case can not be caused, meanwhile, hanging lugs are arranged on the upper edge and the lower edge of the explosion isolation case and are convenient for the installation according to the requirements, in addition, an explosion-proof plug wiring terminal is arranged at the lower side of the explosion isolation case, and in addition, a compacted rubber gasket is arranged in the explosion-proof plug wiring terminal and is used for sealing a gap formed between the wiring terminal and an electric wire. The explosion isolation type LED display screen is a special in-site display device for being matched with an oil material quantitative filling control system, an electronic weighing system and the like, is used in inflammable and combustible dangerous places and can be widely used in dangerous places with explosive gas in the fields of petroleum, chemical engineering, medicine and the like.
Description
Technical field
The utility model relates to a kind of explosion-proof type LED electronic display.
Background technology
The widely used common LED electronic display of existing market is not provided with protective device mostly, is absolutely unsafe if it uses in some specific places that inflammable and explosive substances are arranged, and therefore, is necessary to make improvements.
