The invention relates to the technical field of vehicle sealing, and discloses a sealing structure for a pipeline via hole, which comprises an elastic plug, a through hole is formed in the elastic plug, the lower end of the elastic plug is fixedly connected with an annular support plate, the radius size of the annular support plate is larger than that of the elastic plug, and the through hole is formed in the elastic plug. An annular clamping groove is formed in the upper end of the annular supporting plate, the elastic plug is sleeved with a reinforcing sleeve, the lower end of the reinforcing sleeve is fixedly connected with an annular clamping plate, the annular clamping plate is clamped in the annular clamping groove, and the reinforcing sleeve is fixedly connected with a plurality of clamping plates above the annular supporting plate. The invention aims to provide the elastic plug, the annular support plate, the fixed framework and the annular clamping plate which are matched with one another, when the elastic plug, the annular support plate, the fixed framework and the annular clamping plate are mounted on the metal plate, the metal plate extrudes the annular support plate, and the fixed framework cannot be separated from the elastic plug, so that the elastic plug is not easy to deform and separate when a vehicle moves, and the overall sealing performance is ensured.

    本发明涉及车辆密封技术领域,公开了一种用于管路过孔的密封结构,包括弹性堵头,所述弹性堵头上开设有贯通孔,所述弹性堵头的下端固定连接有环形支撑板,所述环形支撑板的半径尺寸大于所述弹性堵头的半径尺寸,所述环形支撑板的上端开设有环形卡槽,所述弹性堵头上套设有加固套筒,所述加固套筒的下端固定连接有环形卡接板,所述环形卡接板卡接于所述环形卡槽内,所述加固套筒于所述环形支撑板上方固定连接有多个卡板。其目的是:通过弹性堵头、环形支撑板、固定骨架和环形卡接板的相互配合,安装在钣金上时,钣金将环形支撑板挤压,固定骨架无法脱离弹性堵头,使得弹性堵头在车辆运动时不易变形和分离,从而保证了整体的密封性。
