Explosion-proof lamps

Abstract

The invention provides an explosion-proof lamp comprising an upper shell, a lower shell cooperating with the upper shell, a driver and a lamp tube are arranged in the lower shell, the lamp tube is electrically connected to the driver, and the locking device is locked. The switch mechanism of the upper shell and the lower shell. The switch mechanism includes multiple sets of rotating assemblies rotatably arranged on the first side of the lower case, and multiple sets of locking assemblies arranged on the second side of the lower case. The explosion-proof lamp also includes a sealing assembly, which is used for sealing the upper shell and the lower shell. The above-mentioned explosion-proof lamp uses a sealing component to seal the upper case and the lower case, and cooperates with the rotating component and the locking component to lock the upper case and the lower case. At this time, the gap between the upper shell and the lower shell is very small, which can limit the explosive gas, steam or mist from entering the interior of the lamp body to achieve the purpose of explosion protection. When the locking component is released, the upper shell can rotate around the rotating component, which facilitates the opening of the lamp, and the operation is simple and economical.

Description

technical field [0001] The invention relates to the field of lighting lamps, in particular to an explosion-proof lamp. Background technique [0002] During normal work, there are generally no explosive hazardous substances in a potentially explosive gas environment, and these hazardous substances include gases, vapors and mist. Dangerous explosive gases, vapors or mists will only appear in the event of a malfunction, but the chances of such a malfunction are very small, and even if a malfunction occurs, the malfunction exists for a very short time. At present, metal flameproof lamps are generally used for this special gas environment, but such lamps are heavy and costly to manufacture. It is very uneconomical for environments with only potentially explosive gases. Contents of the invention [0003] Based on this, it is necessary to provide an economical explosion-proof lamp that limits the ingress of gas, vapor and mist. [0004] Its technical scheme is as follows. [...
