Abstract
A flame-proof type illumination lamp comprises a metal casing formed by an upper body and a lower body and a glass transparent cover; the upper body and lower body of the metal casing are jointed and take the shape of a cone, and are fastened through an annual thread clamping ring; a conical flame-proof surface is adopted so as to ensure the parameter of the flame-proof gap; the upper body and the lower body of the metal casing are fastened through the annual thread clamping ring, so that the explosion proof effect is improved greatly; the opening and the closing of the upper body and the lower body are very convenient, and the flame-proof surface can not be damaged, so that the service life of the lamp is prolonged.
Description
Technical field:
The utility model relates to a kind of lighting, specifically a kind of flame-proof type lighting that is widely used in inflammable, explosive or medium hazardous area.
Background technology:
The flame-proof type lighting of present domestic employed metal material, its explosion suppresion surface mainly adopts the explosion separation structure of plane formula or seam formula, and the explosion separation structure of plane formula is difficult to reach requirement of explosion proof because the gap of plane engaging surface is not easy control; The light fixture on seam composition surface is opened plug easy damaged explosion suppresion surface, reduces the service life of light fixture.
Summary of the invention:
In view of the deficiency that above-mentioned prior art exists, the purpose of this utility model provides the flame-proof type lighting that the good and unlatching of a kind of explosion-proof effect does not damage explosion suppresion surface.
The purpose of this utility model is achieved in that it comprises metal shell and the glass transparent cover that is made of upper body and lower body, is characterized in that: the upper body of metal shell and lower body composition surface are conical; The upper body of metal shell and lower body are fastening by the ring screw trim ring, make it to reach the requirement of explosion-proof parameter.
The utility model is owing to adopted conical explosion suppresion surface, enable to guarantee the parameter in flame proof gap, upper body and lower body by ring screw trim ring fastening metal shell, improve explosion-proof effect greatly, the folding of upper body and lower body is very convenient, and do not damage explosion suppresion surface, help prolonging the service life of light fixture.
Description of drawings:
Accompanying drawing is the utility model structural representation.
The specific embodiment:
By accompanying drawing as can be known, the utility model mainly comprises the metal shell that is made of upper body 1 and lower body 2 and ring screw trim ring 3, glass transparent cover 4.The upper body 1 and the lower body 2 of metal shell have the taper explosion suppresion surface respectively., two taper explosion suppresion surfaces engage, the upper body of promptly above-mentioned metal shell and lower body composition surface
Be conical; The upper body 1 of metal shell and lower body 2 are fastening by ring screw trim ring 3.
