Barrier-free high-sound-insulating fireproof door for ship

Abstract

The invention relates to a barrier-free high-sound-insulating fireproof door for a ship. The barrier-free high-sound-insulating fireproof door is characterized in that a door leaf (5) and a lifting seal device arranged at the bottom of the door leaf (5) are included, the lifting seal device comprises a fixed frame (1) and a lifting frame (2), at least two sets of lifting linkage devices (3) are connected between the fixed frame (1) and the lifting frame (2), the fixed frame (1) is provided with a sliding groove (1.1), an embedded groove (2.1) is formed in the bottom of the lifting frame (2), each lifting linkage device (3) comprises a sliding block (3.1), a fixed block (3.2), a hinge rod (3.3) and a reset spring (3.4), the sliding blocks (3.1) are arranged in the sliding groove (1.1), and the outer end of the outer sliding block (3.1) is connected with a horizontal contact (4). The barrier-free high-sound-insulating fireproof door for the ship can guarantee that the ground in the fireproof door and the ground outside the fireproof door are equal in level in the using process, and the barrier-free high-sound-insulating fireproof door has a sealing effect in the closing process.

Description

technical field [0001] The invention relates to a barrier-free high-sound insulation marine fire door, which belongs to the field of ships. Background technique [0002] In marine fire doors, the sealing method of the fire doors is to add a ring-shaped rubber seal between the door frame and the door leaf. In the past, the traditional sealing method can only seal the three sides of the door (two sides and one top surface), and the gap between the bottom surface of the door leaf and the ground cannot be sealed by the traditional method. Therefore, it is particularly important to seek a barrier-free high-sound insulation marine fire door that can make the inside and outside of the fire door have no height difference, and can have a sealing effect when closed. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a barrier-free high-sound-insulation marine fire door that can make the inside and outside of the...
