Side door sealing device

Abstract

The invention discloses a side door sealing device which is applied to trains. During specific arrangement, three sealing strips are adopted, and the three sealing strips comprise the upper pressing strip and the two side pressing strips. Due to the facts that a first pressing plate is provided with a horizontal plane longitudinal kidney-shaped hole, a top cover edge beam is provided with a horizontal plane transverse kidney-shaped hole, a first connecting piece connects the horizontal plane longitudinal kidney-shaped hole and the horizontal plane transverse kidney-shaped hole, and a first adjusting gasket is arranged between the horizontal plane longitudinal kidney-shaped hole and the horizontal plane transverse kidney-shaped hole, three-dimensional direction adjustment of the upper pressing strip can be achieved. Due to the facts that a sixth pressing plate is provided with a vertical plane transverse kidney-shaped hole, a C-shaped steel channel is fixed onto a side door column, a second connecting piece connects the vertical plane transverse kidney-shaped hole and the C-shaped steel channel, and a second adjusting gasket is arranged between the vertical plane transverse kidney-shaped hole and the C-shaped steel channel, three-dimensional direction adjustment of the side pressing strips can be achieved. Therefore, even if a stainless steel train body of a city rail train has large welding deformation, the best sealing position can be found out through three-dimensional direction adjustment of the upper pressing strip and the side pressing strips.

Description

technical field [0001] The invention relates to the field of sealing technology, in particular to a side door sealing device. Background technique [0002] A train refers to a multitude of vehicles connected together in succession. Generally refers to a train, especially a connected train consisting of traction locomotives and freight or passenger carriages. There are currently many types of trains. Urban rail trains are one of the trains and are railway transport vehicles that connect cities. It can provide passengers with various services such as business travel and sightseeing. [0003] Urban rail trains have relatively high requirements on their own sealing. At present, the side door column cover and the sealing bead on the side door of domestic urban rail stainless steel trains are mainly fixed to the door post by bolts. The disadvantage is that the thread needs to be matched, and the quantity Many, high work intensity, complex structure of the door column accessorie...

[0003] Urban rail trains have relatively high requirements on their own sealing. At present, the side door column cover and the sealing bead on the side door of domestic urban rail stainless steel trains are mainly fixed to the door post by bolts. The disadvantage is that the thread needs to be matched, and the quantity Many, high work intensity, complex structure of the door column accessories, the sealing strip can only be adjusted forward and backward relative to the door column, due to the large welding deformation of the stainless steel car body of the urban rail train, the sealing effect of the sealing strip will be greatly reduced, and the sealing strip installation High work intensity and low efficiency
