Mounting process for lamp strips of passenger rooms of railway vehicles

Abstract

Mounting process for lamp strips of passenger rooms of railway vehicles comprises steps including that a T5 lamp holder, a T5 electronic ballast and a universal terminal strip are fixed to the lower side surface of a lamp strip top plate, a cable is fixed to one side of a cable fixing plate by the aid of cable ties, the lamp strip top plate is fixed to an inner top plate of a vehicle by a wood screw, a T5 lamp is mounted in the T5 lamp holder, a connecting component and a rotating component are respectively mounted on the inner side and the outer side of a lamp shade, a loudspeaker mounting plate is fixed to the upper side of the lamp shade and provided with a loudspeaker, the outer side of the lamp shade is lifted so that the rotating component is inserted into a rotary shaft support component on the outer side of the lamp strip top plate, the lamp shade rotates around a rotary shaft of the rotating component so that the connecting component on the inner side of the lamp shade is abutted to a folded edge of the lower portion of the inner end of the lamp strip top plate, a quick screw is screwed into a screw hole of the connecting component and a screw hole of the folded edge, and accordingly a lamp strip is fixedly mounted. The assembly process is high in efficiency, the top plate and the lamp shade can be respectively mounted outside the vehicle and then mounted on the vehicle together, mounting efficiency is much higher than that of existing lamp strip mounting process, and assembly precision is high.

Description

technical field [0001] The invention relates to an installation process for a light strip in a passenger compartment of a railway vehicle, and belongs to the technical field of railway passenger vehicle electric lighting. Background technique [0002] The traditional car light belt uses T8 fluorescent tubes, which are connected to the car body frame as a whole, and the size is too large. Due to the small space in the low-floor EMU, the traditional light belt structure cannot meet the requirements. In addition, the bottom surface of the air-conditioning duct in the passenger room is close to the roof of the car, so the speaker cannot be directly installed on the roof of the car. [0003] The applicant invented the figure 1 , figure 2 , image 3 The light strip in the passenger compartment of a railway vehicle includes a light strip top plate 1 fixed to the interior roof plate 24 by wood screws 19, a lampshade 2 located below the light strip top plate 1, and a rotating par...
