Improved multifunctional lighting lamp

Abstract

The invention discloses an improved multifunctional lighting lamp, and relates to the technical field of construction lighting lamps. The improved multifunctional lighting lamp comprises a base, which is of a structure shaped like a Chinese character 'yue', wherein two auxiliary supporting frames are symmetrically and slidably inserted into supporting rods on the left side and the right side of the base, a swing rod is rotationally installed on the middle section of the supporting rod in the middle of the base, a handle rod is welded to the head end section of the swing rod in an extending and protruding mode, two positioning bolts are installed on the handle rod in a screwing mode at intervals, two transverse support positioning shafts are symmetrically welded to the top ends of the middle sections of supporting rods on the left side and the right side of the base, a shear fork mechanism is slidably installed on the two transverse support positioning shafts, and the whole horizontal supporting frame is formed by jointly welding a front strip-shaped track frame, a rear strip-shaped track frame and three longitudinal connecting plates welded between the two strip-shaped track frames at equal intervals. According to the invention, when the two auxiliary supporting frames and the shear fork mechanism slide and contract, the overall supporting occupied area of the lighting device can be greatly reduced, and the problem that an existing lighting device is large in overall occupied area and inconvenient to transfer is solved.

Description

technical field [0001] The invention relates to the technical field of construction lighting fixtures, in particular to an improved multifunctional lighting fixture. Background technique [0002] During the construction of roads and factory buildings, in order to ensure normal operation at night, it is necessary to illuminate the lighting construction site, which will use an improved multifunctional lighting fixture. [0003] Most of the existing construction lighting lamps can be adjusted up and down, but the lifting mechanism of the lamps will change the overall center of gravity of the lighting device when it is lifted up and down, and it is easy to cause the center of gravity to be unstable and topple over. In addition, although some lighting devices are equipped with Auxiliary support components can be telescopically adjusted to increase support stability, but most of the auxiliary support components cannot be linked with the lifting mechanism and combined with synchron...

Problems solved by technology

[0004] In view of this, the present invention provides an improved multi-functional lighting fixture, which has an L-shaped pull rod. Through the power transmission of two L-shaped pull rods, the two sliding frames can drive the two sliding shafts on the bottom side when they slide and expand in opposite directions. Sliding together, linked to control the lifting of the scissor mechanism, which saves the trouble of additional manual effort to operate the lifting of the three spotlights, and solves the problem of low efficiency of the overall retraction operation of the lighting device
