Abstract

A subway seal strip is mounted at the edge of a vertical door cover between a door and a side wall through bolts and used for sealing the door and comprises a rubber strip and a steel plate. The rubber strip is fixed to the steel plate which is fixed to the vertical door cover through the bolts, and the subway seal strip is as high as the vertical door cover to achieve great airtightness of the subway door and is adjustable in extending length. In addition, the subway seal strip has great soundproof, dustproof, waterproof, fixing and damping effects.

Description

technical field [0001] The invention relates to the field of railway train sealing, in particular to a subway sealing strip with adjustable extension length, tight sealing, no waves, and steel plate composite. Background technique [0002] With the rapid development of science and technology, people travel faster and faster between the two places. The train came into being, which greatly shortened the time people spend on the road. The high speed of the train is very high, which requires very high comfort. The sealing design of the door system of high-speed trains is particularly important, it plays the role of shock absorption, waterproof, sound insulation, heat insulation, dustproof, and fixation. But no matter what kind of shape and structure the existing sealing strip is, such as application number: 201620446034.8, publication number: CN 205778392 U utility model patent: a kind of door and window sealing strip for rail transit; application number: 201320304669.0, publica...
