Abstract

The invention discloses an explosion-proof electric horn and belongs to explosion-proof vehicle fittings. A conventional explosion-proof electric horn is just suitable for a few places, low in sound, high in power consumption, and is not very suitable for explosion-proof vehicles used in the multiple places. A housing, a cover, and a hood are assembled together. A first receiving cavity is formed between the housing and the cover. A second receiving cavity is formed between the cover and the hood. An electric horn body is assembled in the first receiving cavity. A sound generating diaphragm is located in the second receiving cavity. An axially movable core shaft passes through the cover and has its both ends connected with the electric horn body and the sound generating diaphragm respectively. An explosion-proof cable introducing device is assembled on the housing. A cable is introduced into the first receiving cavity by the explosion-proof cable introducing device and is connected with the electric horn body. The explosion-proof electric horn has a good gas and dust explosion-proof effect, loud in sound, low in power consumption, simple in structure, easy to manufacture, and suitable for most explosion-proof vehicles.

Description

technical field [0001] The invention belongs to explosion-proof vehicle accessories, in particular to an explosion-proof electric horn used for the electrical system of the explosion-proof vehicle. Background technique [0002] Existing explosion-proof vehicles are mostly explosion-proof grades for single places, the highest gas explosion-proof grade is Ex desⅡC T4 Gb, and the highest dust explosion-proof grade is Ex tD A21 IP65 T130℃. Most of the existing explosion-proof electric horns are explosion-proof designs for a single place, which cannot be applied to vehicles with explosion-proof gas and dust at the same time. At present, the market demand is mostly explosion-proof vehicles that can be used in explosive gas environments and combustible dust environments at the same time. Therefore, explosion-proof electric horns equipped with explosion-proof vehicles must also meet the requirements of gas and dust explosion-proof at the same time, and the explosion-proof grades are...
