Abstract

The invention relates to a lamp seat fixing structure which comprises a bracket, a supporting piece and a fastening ring. The supporting piece comprises a transverse part and two longitudinal parts, the two ends of the transverse part are extended upwards to form the two longitudinal parts, and the transverse part is fixed on the bracket; the fastening ring comprises a ring-shaped piece with an opening, the ring-shaped piece is arranged between the two longitudinal parts and is respectively connected with the two longitudinal parts in a fixed manner, the two ends at the position of the opening of the ring-shaped piece are respectively extended outwards to form locking sheets, and the fastening ring further comprises a fastening piece used for leading the two locking sheets to be selectively close to or separated from each other. The lamp seat fixing structure has the following characteristics: the lamp seat fixing structure fixes a ceramic lamp seat along the circumferential direction of the ceramic lamp seat by the shrinking of the ring-shaped piece with the opening, so that the force bearing area is large and uniform; furthermore, the bracket can be extended to form a fixing piece and the lamp seat can be further fixed by the bottom part thereof, so as to lead the lamp seat fixing structure to be more reliable; in addition, the lamp seat fixing structure also has certain effect of shock prevention.

Description

technical field [0001] The invention relates to a fixing structure of a lamp holder in a lamp, and more specifically relates to a fixing structure of a lamp holder. Background technique [0002] Ceramic lamp holder is a commonly used lamp holder, which is often used in some lamps with high heat generation such as incandescent lamps and halogen lamps. When the ceramic lamp holder is fixed, it is generally fixed on the bracket through the screw holes on it or the screw holes embedded in it and the screws. Damage, especially in some harsh environments, such as mines, will also be subject to strong mechanical vibrations, often causing the ceramic lamp holder to loosen, and it is also easy to damage the bulb in the lamp holder. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a lamp holder fixing structure with simple structure and reliable fixing for the disadvantages of poor reliability and easy damage of the cerami...
