Abstract

The invention relates to the technical field of railway vehicles and particularly relates to a folding shed windshield structure of a railway vehicle. A welding column is fixedly connected with a transition plate frame, a fixing bolt is in threaded connection with the transition plate frame, a butt joint plate is detachably connected with the transition plate frame, a clamping piece is fixedly connected with the butt joint plate, a windshield is fixedly connected with the butt joint plate, when installing and connecting the windshield, the transition plate frame is firstly welded and fixed with a carriage through welding columns, then the windshield is connected and fixed with the butt joint plate, a protrusion of the butt joint plate is inserted into a mounting groove of the transition plate frame, the protrusion is clamped with the mounting groove, clamping pieces on the two sides of the protrusion are inserted into clamping grooves in the two sides of the mounting groove respectively, the transition plate frame and the butt joint plate are firmly clamped and fixed, and the fixing bolt is rotated to be inserted into the fixing hole in the butt joint plate. The connecting and fixing effect of the transition plate frame and the butt joint plate is enhanced, and a problem that flash seams are prone to occurring due to the fact that an existing folding shed windshield is not enough in locking force is solved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a bellows windshield structure for rail vehicles. Background technique [0002] With the current increase in the operating speed of domestic main-line railways and urban light rail transit, higher design standards have been put forward for the comfort of the passenger compartment environment on the basis of the safe use of vehicle supporting facilities and structural stability. The bellows windshield is one of the important parts, it is set at both ends of the compartment, it acts as a flexible connection between the two compartments, and it is also a through passage connecting the two compartments for passengers to pass through. [0003] In the prior art, the bellows windshield for rapid decompilation is first to install the transition plate composition on both sides of the vehicle through screws, and then hang and fix the bellows windshield docking frame composition on th...
