The utility model relates to an abnormal pressure alarm device for a fire extinguisher. The abnormal pressure alarm device comprises fire extinguisher pressure gauges, an alarm device body and magnetic buckle joints; two sensors are respectively arranged in a super-charging indication area and an under-charging indication area of a panel of each fire extinguisher pressure gauge, and each sensor is electrically connected with the alarm device body through the magnetic buckle joint; each magnetic buckle joint comprises an auxiliary buckle and a primary buckle, an output line of each sensor and an input line of the alarm device body are respectively arranged on the auxiliary buckle and the primary buckle; the alarm device body comprises an under-charging warning lamp and a super-charging indication lamp. The abnormal pressure alarm device has the benefits that the pressure state of the fire extinguisher can be monitored at any time; as the sensors are electrically connected with the alarm device body through the magnetic buckle joints capable of being conveniently divorced, the magnetic buckle joints capable of being conveniently divorced cannot influence the normal use of the fire extinguisher; when emergency use is needed, the joints can be automatically disconnected under the action of outside force, so that an alarm circuit is protected from damage.
