In order to solve the problems that in an existing railway vehicle folding shed, a sewing thread of a
windshield shed cloth floats on the surface of the shed cloth, so that the sealing performance and the strength of a folding shed
windshield are reduced, and an aluminum profile cracks after being flared and crimped, the utility model provides a sewing thread structure of a folding shed
windshield shed cloth, which comprises a composite layer of shed cloth, a sewing thread and a groove, the shed cloth of the composite layer sequentially comprises a surface glue layer, a fabric layer, a bonding layer, a fabric layer and a surface glue layer in the thickness direction. Two grooves are formed in the surface of the surface glue layer on the outer side of the two
layers of shed cloth at the
lap joint of each annular shed cloth
assembly, the grooves are formed in the width direction of each annular shed cloth
assembly, and the positions of the grooves in the two
layers of shed cloth correspond to each other; the sewing thread is arranged in the groove; the utility model has the advantages of simple structure and convenience in
processing, solves the problem that the sewing thread of the
vestibule windshield is broken by abrasion, and prolongs the service life of the windshield; the
cracking risk caused by the flaring width of the aluminum frame is reduced, potential safety hazards are reduced, and meanwhile the maintenance cost and maintenance difficulty of the
bellows windshield are reduced.
