Abstract

The invention provides a door lock indicating device based on air pressure, and relates to the technical field of door locks. The door lock indicating device based on air pressure includes: a door frame, the side of the door frame is fixedly connected with a mounting plate; a door lock indicating mechanism, the door lock indicating mechanism is connected with the mounting plate and the door frame, and the door lock indicating mechanism includes an elastic Airbag, connecting plate, mounting seat, protective sleeve, indicator airbag, internal thread airway, external thread connecting pipe and magnetic strip, the rear end face of the door frame is connected with elastic airbag through connecting plate, when the door is closed, the movable door and elastic airbag contact; the outer surface of the mounting plate is fixedly connected to the mounting seat, and the mounting seat is provided with an internal thread air passage, which communicates with the elastic air bag through the air guide tube, and the internal thread air passage is sealed with an external thread connecting pipe . The air pressure-based door lock indicating device provided by the invention has the advantage of good indicating effect.

Description

technical field [0001] The invention relates to the technical field of door locks, in particular to a door lock indicating device based on air pressure. Background technique [0002] Public toilets, referred to as public toilets, refer to toilets shared by urban residents and floating population, including toilets attached to public buildings (such as stations, hospitals, cinemas, exhibition halls, office buildings, etc.). According to building form, building structure, building grade, space characteristics, flushing method, management method or investment channel, etc., public toilets can be classified in many ways. [0003] At present, when the movable door lock in the public toilet is closed manually, only a small picture is changed, which is small in size and not three-dimensional enough, which is not conducive to the observation of external personnel and is likely to cause confusion. [0004] Therefore, it is necessary to provide a new air pressure-based door lock indi...
