Illuminating lamp device

Abstract

An illuminating lamp device comprises a lamp holder and a lamp base. A turning hole with a rightward notch is formed in the lamp holder. A turning piece is rotatably mounted in the turning hole. A left insertion groove and a right insertion groove communicating with the left insertion groove are formed in the turning piece in a vertically corresponding mode. Wafers are fixedly mounted in the insertion grooves. A compression sheet is fixedly mounted on the midpoint of the left end face of the turning piece, and a hole is formed in the left end face of the compression sheet. An annular groove is formed in the portion, located at the left end of the turning hole, of the lamp holder, a midpoint groove is formed in the midpoint of the left end of the annular groove, and a horizontal sliding piece is mounted in the midpoint groove and can horizontally slide left and right in the midpoint groove. A fixing pin is fixedly mounted on the midpoint of the right end face of the horizontal sliding piece. A semicircular groove which is located behind and above the horizontal sliding piece and a semicircular groove located in front of and below the horizontal sliding piece are formed in the end wall of the annular groove. Pushing grooves which stretch up and down are arranged in the end wall of the annular groove in a vertically corresponding mode and communicate with the semicircular grooves. Charged sliding blocks are mounted in the pushing grooves in a horizontal sliding mode.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a lighting device. Background technique [0002] In bridge construction, some lighting lamps are generally installed for bridge night lighting. However, these lighting lamps are generally fixed and connected by fastening bolts. , the operation is cumbersome and complicated, which greatly reduces the efficiency of maintenance. At the same time, the lamp holders of the existing bridge lighting lamps are generally connected to the mains. Contact with the conductive parts of the battery can easily cause electric shock accidents, and there is a great potential safety hazard. Contents of the invention [0003] The object of the present invention is to provide a lighting device for overcoming the above-mentioned defects in the prior art. [0004] A lighting device according to the present invention, comprising a lamp holder and a lamp cap, the lamp holder is provided with a turning hole with ...
