Novel locking steel door used for ship

Abstract

A novel locking steel door used for a ship comprises a door plate, a door frame, a hinge, a handle, a connecting rod, a rolling head, a pulling handle, a tapered wedge, a sealing strip, a connecting plate, a transmission shaft and a nut. The handle, the connecting rod, the rolling head, the pulling handle, the tapered wedge, the connecting plate, the transmission shaft and the nut are matched with one another to be assembled into a locking transmission device. The door plate adopts a stamping process, regular concave and convex parts are arranged on the surface of the shape of the door plate, and the door plate is provided with an observation window. According to the novel locking steel door used for the ship, the arrangement of the locking transmission device and the design of the door plate are optimized, so that the weight of the door plate of the steel door is significantly reduced, and opening and closing of the steel door are more convenient; and meanwhile, the strength and the stiffness of the door plate are not reduced, and the locking and unlocking functions as well as the working reliability of the steel door are not affected.

Description

technical field [0001] The invention relates to a novel locking steel door for ships, which belongs to the technical field of special devices for ships. Background technique [0002] Marine doors are divided into steel doors, stainless steel doors, aluminum doors, glass steel doors and wooden doors according to their main materials. Steel doors are usually set on the peripheral wall of the superstructure or the main transverse partition. Usually, steel doors also have requirements for airtightness (weathertight, watertight, airtight) and fire protection. [0003] For the steel doors of my country's marine standard, the locking and transmission devices are usually set on the door panels, resulting in heavy door panels and laborious opening and closing, especially for steel doors on the inclined walls of superstructures, which are more laborious to open and close, and the operation is very inconvenient . Therefore, considering the inconvenience of using the current steel door...
