Bridge illuminating lamp device

Abstract

A bridge illuminating lamp device comprises a lamp seat and a lamp holder matched with the lamp seat in use. A first annularly-connected groove with a groove port facing the left end is formed in the lamp holder; a shell sleeve is mounted in the first annularly-connected groove in a slidably connecting mode; inserting columns located in the shell sleeve are mounted on the left end face of the lamp holder in an up-down opposite mode; vertically-through penetrating holes are formed in the inserting columns; a middle groove is formed in the lamp seat; a transferring part is mounted in the middle groove in a transferring mode; inserting grooves matched with the inserting columns are formed in the transferring part in an up-down opposite mode; first electric connecting pieces are fixedly mounted on the left sides of the inner walls of the inserting grooves; first inserting holes and second inserting holes are further formed in the left end face of the transferring part, wherein the first inserting holes are formed in an up-down opposite mode, and hole ports of the first inserting holes face leftwards, and the second inserting holes are formed in an front-rear opposite mode; a square groove with an groove port facing leftwards is formed in the middle of the left end face of the transferring part; second electric connecting pieces are fixedly mounted on the upper and lower end walls of the square groove; a sliding connecting groove is formed in the position, located at the left end of the middle groove, of the lamp seat; and a sliding connecting block is mounted in the sliding connecting groove in a left-right sliding connecting mode.

Description

technical field [0001] The invention relates to the technical field of bridge lighting, in particular to a bridge 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 bridge lighting device for overcoming the above-mentioned defects in the prior art. [0004] A bridge lighting device according to the present invention, comprising a lamp holder and a lamp cap used in conjunc...
