Padlock latch for escape

Abstract

The invention discloses a padlock latch for escape, comprising an inner door mechanism and an outer door mechanism. A conventional bolt and butterfly nut structure for escape is replaced by a mode ofcombining a tenon and a bevel slider; after the tenon and the bevel slider are staggered, the bevel slider does not limit the axial movement between a handle and the latch any more, so that the padlock latch is quickly unlocked; the handle part increases the arm of force of a rotating part, so that the operation is more labor-saving, and the personnel operation difficulty caused by overlarge locking force is prevented; the outer edge of the tenon is consistent with the diameter of the inner surface of the handle, so that the tenon can only rotate relative to the handle after being pressed intothe handle; moreover, the surfaces of the tenon and the handle are inclined, so that the axial pressure between the tenons and the handle can be changed when the handle rotates, the tenon and the bevel slider can be conveniently staggered, and the bevel slider on the handle is hidden in the handle; and meanwhile, the tenon of the latch is covered by the handle, and the inner side structure of thedoor is of built-in design, so that the appearance is more attractive compared with common exposed nuts and bolts.

Description

Technical field[0001]The invention relates to the technical field of padlock buckles, in particular to a padlock buckle for escape.Background technique[0002]At present, ships have planned escape routes for the safety of their crews, and the steel doors on the routes need to be equipped with padlocks due to factors such as preventing outsiders from entering. For this reason, the steel doors on the general escape routes The door will be equipped with an escape padlock. The lock is fixed to the frame of the steel door from the inside of the door with a wing nut. Because the outsider cannot operate the wing nut and cannot enter from the outside when the door is locked, he needs to escape At this time, the personnel can remove the wing nut from the inside, and the lock will fall off the door frame, thus ensuring the escape route for the personnel.[0003]However, at present, the padlocks used for escape on ships’ steel doors are fixed by wing nuts. In case of fire and other emergency situa...

Problems solved by technology

[0003] However, at present, the padlock buckle used for escape on the ship's steel door is fixed by a wing nut. When encountering an emergency such as a fire, it needs to be rotated several times to remove the buckle. This design takes a long time to operate, and it may also be because The staff panicked and the size of the nut was relatively small, resulting in misoperation, unable to escape immediately, which made the overall convenience and practicability unsatisfactory.
