The invention discloses a bulb loosening-prevention structure belonging to the field of lighting. The structure is arranged on a lamp-socket supporting plate; a lamp socket and a bulb plugged on the lamp socket are arranged on the lamp-socket supporting plate; the bulb loosening-prevention structure comprises a bulb pressing plate for applying stable pressure on the lamp socket and the head of the bulb, and a slide groove part fixed on the lamp-socket supporting plate; the bulb pressing plate comprises a movable end part, a movable end part and a convex part between the movable end parts; themovable end parts of the bulb pressing plate are movably connected to the lamp-socket supporting plate; the convex part of the bulb pressing plate crosses the lamp socket and the head of the bulb andis in fitting contact with the head of the bulb; and the movable end part of the bulb pressing plate is slidably arranged on the slide groove part. Compared with the prior art, the invention fixes the head of the bulb by adding the bulb pressing plate arranged on the lamp-socket supporting plate, prevents the head of the bulb from being loosened from the lamp socket after being vibrated so as to avoid abnormal black out or vibrated cracking of the bulb and reduces the maintenance cost of the bulb.
Description
technical field [0001] The invention relates to a light bulb anti-loosening structure, in particular to a light bulb anti-loosening structure of a metal halide lamp. The invention also relates to a lamp using a light bulb anti-loosening structure. Background technique [0002] At present, metal halide lamps are generally used as light sources for flood lighting in coal mine underground roadways and caverns, or other places such as large mechanical operation squares. This light source has the advantages of strong illumination and wide irradiation range. However, in the above-mentioned workplaces, when the large-scale mechanical equipment is in normal operation, it often brings certain vibration to the workplace. There are loose and virtual connections between the sockets, causing the lamps to go out abnormally and affecting the normal operation of the operators; in serious cases, the metal halide lamps are loosened from the lamp sockets and broken, which increases the maint...
