Movable doorsill type sealing door

Abstract

The invention discloses a movable doorsill type sealing door. The door comprises a door frame and a door plate rotationally installed on the door frame, the bottom of the door frame is open, and a doorsill is rotationally installed on the side face, located at the lower portion of the door plate, of the door frame. The first side of the doorsill is hinged to the door frame, and at least one firstrolling buckle is arranged between the second side of the doorsill and the door frame. The first rolling buckle comprises a first rolling buckle end, a first middle part and a second rolling buckle end which are sequentially arranged and integrally formed, the first middle part is hinged to the doorsill, the first rolling buckle end is rotationally connected with a wedge-shaped groove reserved inthe corresponding door frame, and the second rolling buckle end extends along the direction away from the first rolling buckle end. The movable doorsill type sealing door can be selectively opened andclosed, the passing obstacles of cart type equipment or goods are avoided, the requirement for barrier-free rapid passing can be met, and the using occasions of the sealing door are increased.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a movable threshold type hermetic door. Background technique [0002] In the construction of steel ships, steel weathertight doors with openable sills mostly adopt the following structure, that is, the weathertight doors include a door frame and a door panel, wherein the door frame is rectangular, and there is a fixed threshold at the bottom of the door frame to prevent carts The passage of type equipment or goods, and due to the heavy weight of cart-type equipment or goods, several staff members are required to manually push or lift the cart through the airtight door when passing through the airtight door, which consumes a lot of manpower, and due to the fixed The sill has a certain height, even if a transition cover is installed on the fixed sill, when the cart passes by the gravity on the fixed sill, the speed of the cart is faster, and the staff needs to control the speed of th...
