Description

Fire pre-alarm device Technical Field The utility model relates to the technical field of fire early warning, in particular to a fire pre-warning device. Background The fire alarm device is mainly used for detecting smoke, high temperature or flame in the initial stage of fire, reminding people to evacuate and starting fire extinguishing measures through audible and visual alarm, furthest reducing casualties and property loss, is suitable for places such as families, markets, office buildings and the like, and particularly plays a role in the gold escape time of 15-120 seconds in the initial stage of fire. In order to prevent to cause the outage when the conflagration breaks out, current fire alarm can be from taking independent power supply usually, ensure when the conflagration takes place, fire alarm can normally work, send out the alarm, because take independent power supply certainly, so need the time of taking over just detect and change the independent power supply of fire alarm, current fire alarm's power supply installation socket is located the installation face of fire alarm and wall body generally, thereby when need examining the change to independent power supply, taste need take off the fire alarm from the wall body, very inconvenience, and current fire alarm is usually through sticky glue such as 3M glues on the wall body, can generally lead to sticky glue inefficacy or viscidity weakening after taking down, need change gluey when installing again, cause the waste of resource. There is therefore a need to propose a new solution to this problem. Disclosure of utility model The object of the embodiment of the utility model is to provide a fire pre-alarm device for solving the above problems. The technical aim of the embodiment of the utility model is achieved by the following technical scheme that the fire pre-alarm device comprises an alarm device body and an installation seat, wherein the alarm device body is in sliding fit with the installation seat, a power socket for power installation is arranged in the alarm device body, a cavity in sliding fit with the power socket is arranged in the alarm device body, a metal gasket is arranged on the inner wall of the cavity, a metal protrusion abutted against the metal gasket is arranged on the power socket, and a limiting mechanism for limiting the power socket is arranged between the alarm device body and the power socket.
