Detailed Description

The present invention will be described in further detail with reference to the drawings and embodiments, but the following embodiments are only illustrative and do not limit the scope of the present invention.

As shown in fig. 1 and 2, the utility model comprises a lock body mechanism (13), a stay wire swing arm (18), a first nut (15), a second nut (16), a split pin (17), a stay wire (11), a steering swing arm (9), a connecting rod (5), an unlocking mechanism, a spring seat (10) and a spring (9). The lock body mechanism (13) is arranged on a door frame (12) on the side edge, a hole matched with the rotating rod (14) in the lock body mechanism (13) is formed in the pull wire swing arm (18), the pull wire swing arm (18) is fixed on the rotating rod (14) through a first nut (15) and a second nut (16), and a split pin (17) is installed behind the second nut (16). A steering swing arm (9) of the steering mechanism is arranged on the outer side of the door lintel (8), namely one side close to the wall of the well through a first rotating shaft (6). And a push-turn swing arm (4) and an unlocking swing arm (2) on the unlocking mechanism are respectively arranged on the inner side and the outer side of the door lintel through a second rotating shaft (3). The spring is mounted (10) on the outer side of the door lintel (8) by means of a spring seat.

When the door is opened, the triangular key is inserted into the lock body mechanism (13) and rotates forcibly, so that the stay wire swing arm (18) arranged on the rotating rod (14) in the lock body mechanism (13) rotates, the stay wire swing arm (18) pulls the steering swing arm (9) to rotate anticlockwise on the rotating shaft I (6) through the stay rope (11), the steering swing arm (9) pushes the pushing swing arm (4) to rotate anticlockwise on the rotating shaft II (3) through the connecting rod (5), and meanwhile, the unlocking swing arm (2) arranged on the inner side of the door lintel (8) is driven to rotate, and the movable door lock hook (1) is opened.
