Smoke alarm with wide application range

Abstract

The invention discloses a smoke alarm with a wide application range. The top of an alarm body is fixedly connected with a mounting base; a fixed seat is arranged above the mounting base; the top of the fixed seat is fixedly connected with a ceiling; the mounting base is detachably connected with the fixed seat; a blade protection device is arranged around the alarm body; the bottom of the inner cavity of the mounting base is provided with a sliding part base; a horizontal sliding part is arranged in the sliding part base; the sliding part base is vertically connected with a fixed seat lockingpart; horizontal clamping rods are arranged over against each other on both sides of the fixed seat locking part; and the two horizontal clamping rods are fixedly with the horizontal sliding part through stabilizer rods respectively. Compared with the prior art, the smoke alarm has the advantages of compact structure and high practicability. A user can easily and conveniently realize the mounting,fixation and disassembly between the mounting base and the fixed seat with a good stabilizing effect. Meanwhile, a protective blade can be contracted and protected on the outer side of the alarm to form a protective wall, so that the device can be insulated to a certain extent, and has an own protective function.

Description

technical field [0001] The invention relates to the technical field of alarms, in particular to a smoke alarm with a wide application range. Background technique [0002] Fire refers to a catastrophic burning phenomenon that is out of control in time or space. Among various disasters, fire is one of the main disasters that most often and most commonly threaten public safety and social development. Human beings can use and control fire, which is an important symbol of the progress of civilization, so smoke alarms were invented, also known as fire smoke alarms, smoke alarms or smoke sensors, etc., which are powered by the bus, and multiple , network and communicate with the fire alarm controller to form an alarm system. There is no sound at the scene when the alarm is triggered, and the host has sound and light prompts. [0003] Defects of the prior art: At present, the commonly used installation methods for smoke alarms are mostly to fix the smoke alarms to the wall or the s...
