The utility model relates to the technical field of cabin door locks, and discloses a cabin door locking structure which comprises a main body mechanism and an auxiliary mechanism, the auxiliary mechanism is located at the rear end of the main body mechanism, the main body mechanism comprises a cabin plate, a cabin door frame and a cabin door plate, and the cabin door frame is fixedly installed at the rear end of the cabin plate. According to the cabin door locking structure, by installing the main body mechanism, when a lawless person enters, a sailor can open a cabin door to hide in a cabin, then the cabin door is closed, a bolt is inserted into a fixing block, a locking hook is hung in a hole in a limiting block, limiting is conducted through an anti-theft lock chain, the lawless person is prevented from prizing the cabin door, and the safety of the sailor is improved. And finally, the handle is rotated, so that the rotating block drives the limiting rod to rotate, the limiting rod is used for blocking the cabin door plate for fixing, and the situation that lawbreakers intrude into the cabin is avoided. According to the locking structure, by improving the main body mechanism, the anti-theft performance is greatly improved, safety is improved, and life and property losses in the cabin are avoided; and the practicability of the cabin door locking structure is improved.

The utility model belongs to door lock alarm device field, specifically disclose door lock state detection automatic alarm subassembly, including the buckle plate and the buckle box that connects on the buckle plate, is seted up with the buckle hole that communicates with the buckle box on the buckle plate, is fixed with the buzzer, the metal swing arm that can swing, the coil assembly and the power supply assembly that is electrically connected with the coil assembly in the buckle box, the one end of coil assembly is opposite the buckle hole, its opposite another end is opposite the metal swing arm, and is set up with the metal swing arm interval, the first electric component that is fixed in the buckle box is equipped on the side of the metal swing arm that is away from the coil assembly, the first electric component is respectively with the first pole of buzzer and the single pole electric connection of power supply assembly, the one end of metal swing arm is connected with the buckle box and has the tension spring, the swing fulcrum of metal swing arm is located between the tension spring and coil assembly, the second electric component that is opposite the first electric component is equipped on the opposite another end of metal swing arm, this scheme can realize the automatic reminding of switching door and the hand of the person in the door opening closes the door.

The utility model belongs to the technical field of handrails, and particularly relates to a mechanical operation safety warning handrail which comprises a bottom plate, a top plate arranged on the lower surface of the bottom plate, stand columns symmetrically and fixedly connected to the side, close to the bottom plate, of the surface of the top plate, and an alarm assembly arranged between the bottom plate and the top plate. The alarm assembly comprises an infrared sensor installed on the front surface of the top plate, a controller installed on the side, close to the infrared sensor, of the front surface of the top plate and a buzzer installed on the upper surface of the top plate, and the buzzer is electrically connected with the infrared sensor. Through the arranged alarm assembly, an alarm can be given out to people intruding into the operation area in time, the people intruding into the operation area are prevented from being hurt, then the practicability of the device is enhanced, through the arranged fixing assembly, the device can be stably fixed to the operation area, the operation area can be isolated from the operation area before operation, and the practicability of the device is improved. People are prevented from intruding into the operation area.
