Lighting lamp

Abstract

The invention relates to a lighting lamp, comprising a barrel with two opened ends, a lighting assembly arranged in the barrel, and a cover arranged on an end of the barrel, wherein an end surface of the cover extends outwards to form at least two connection arms; connection arms are provided with openings; the lighting lamp further comprises a fixed frame and a knob assembly, wherein a through hole through which an extension arm passes; a knob is rotated to drive the extension arm to rotate by certain angle to be inserted in the through hole, so that a second end is inserted into the through hole, the extension arm leans against an inner wall of the barrel, and the cover is locked with the barrel; the knob is rotated to drive the extension arm to rotate by certain angle to perforate from the through hole, so that the second end leaves the through hole, and the cover is separated from the barrel. A portable fixing mode for the cover and the barrel is provided by the invention. The knob can be rotated directly to make the extension arm of a rotary handle perforate from or extend into the through hole on the barrel, so that the cover can be locked with or separated from the barrel without loosing bolts or other parts, thereby shortening maintenance time, and increasing efficiency.

Description

technical field [0001] The invention relates to the field of lighting, and more specifically, to a lighting fixture.
