Abstract

The invention relates to a lamp fixing device capable of adjusting an illumination angle and a lamp. The lamp fixing device comprises a fixing seat, a first adjusting disc and a second adjusting disc, wherein the fixing seat is used for connecting a lamp holder; the first adjusting disc is arranged on the fixing seat and is provided with a first serrated face; and the second adjusting disc is provided with a second serrated face. Teeth capable of coinciding with one another to lock the lamp at different illumination angles are arranged on the first and second serrated faces; an adjusting bolt sequentially passes through the second adjusting disc, the first adjusting disc and the fixing seat; a nut is arranged at one end of the adjusting bolt, which runs through the fixing seat; a gap is reserved between the nut and the fixing seat; and a spring used for jacking the fixing seat and the first adjusting disc and making the first serrated face fitted with the second serrated face is arranged at the gap. The lamp fixing device can conveniently adjust the illumination angle of the lamp holder with a single hand and also can reliably adjust the illumination angle when the fixing seat is connected with a relatively heavy lamp holder.

Description

technical field [0001] The invention relates to a lighting lamp, in particular to a lamp fixing device and a lamp with an adjustable irradiation angle. Background technique [0002] The lamps used in the railway operation environment need to check the top surface and inner and outer sides of the track when performing track maintenance, and need to rotate to adjust the irradiation angle of the lamp head of the lighting lamp. However, in the existing adjustment discs, some are realized by punching holes and using bolts. During operation, it is necessary to pull out the bolts and then turn the lamp head of the lighting fixture. It is necessary to operate simultaneously with both hands to realize the adjustment of the lamp head irradiation angle. [0003] Some adjustment discs that are operated with one hand are pressed by nuts, and the adjustment function of the lamp head irradiation angle is realized by overcoming the friction force. This structure can only bear the adjustment...
