Embodiment 1

[0028] Such as Figure 1-Figure 4 As shown, the present invention provides an alarm, including a casing 1, a discharge device disposed in the casing 1, and a discharge tool 2, and the discharge tool 2 is pivotally connected to the casing 1;

[0029] The shell 1 is provided with a first shaft hole 11, a preset hole 12 and a limit hole 13;

[0030] The discharge device includes a start switch 3 for turning on the discharge function;

[0031] The discharge tool 2 includes a main body 21, a first rotating shaft 22 arranged at one end of the main body 21, an elastic arm 23 and a lever 24 arranged on the side of the main body 21, and a limit block 25 is arranged on the elastic arm 23;

[0032] The first rotating shaft 22 is placed in the first shaft hole 11, and the limit block 25 is set in the preset hole 12;

[0033] When the discharge tool 2 rotates around the first rotating shaft 22, the limit block 25 breaks away from the preset hole 12 and enters the limit hole 13, thereby r...

Embodiment 2

[0040] Such as figure 1 As shown, the present invention provides an alarm, comprising a housing 1, a discharge device and a discharge tool 2 arranged in the housing 1, a hanging board 4, the hanging board 4 is fixedly arranged on the wall or ceiling, the housing 1 and the hanging board 4 Fixed connection. There are many ways to connect the shell 1 and the hanging plate 4, such as elastic undercut connection, hook connection, fastener connection and so on. A first shaft hole 11 , a preset hole 12 and a limiting hole 13 are defined on the surface of the casing 1 adjacent to the hanging plate 4 . When the alarm is in normal use, the shell 1 is fixedly connected to the hanging plate 4, the first shaft hole 11 is covered by the hanging plate 4, and the discharge tool 2 cannot be rotated. The rotating discharge tool 2 needs to remove the alarm from the hanging plate 4, The first shaft hole 11, the preset hole 12 and the limit hole 13 are arranged on the surface adjacent to the han...

Embodiment 3

[0042] Such as figure 1As shown, the present invention provides an alarm, including a casing 1, a discharge device disposed in the casing 1, a discharge tool 2 and a printed board 5, and a start switch 3 of the discharge device is fixedly arranged on the printed board 5. Moreover, the discharge tool 2 is pivotally connected to the printed board 5 . For example: the second shaft hole 51 is set on the printed board 5, the other end of the main body 21 of the discharge tool 2 is provided with the second rotating shaft 27, and the second rotating shaft 27 is placed in the second shaft hole 51, so that the second rotating shaft 27 revolves around the second The shaft hole 51 rotates; or a second shaft hole 51 is set on the printed board 5, a rotating shaft is fixedly arranged in the second shaft hole 51, and a shaft hole is arranged at the other end of the main body of the discharge tool 2, so that the rotating shaft is in the shaft hole rotate. The two ends of the main body 21 o...

Abstract

The invention, which is applicable to the technical field of security, provides an alarm device comprising a housing, a discharging device and a discharging tool. The discharging tool is pivotally connected with the housing; and a first shaft hole, a preset hole and a limit hole are formed in the housing. The discharging device includes a start switch. The discharging tool includes a main body, afirst rotating shaft, an elastic arm and a driving lever; a limiting block is arranged at the elastic arm; the first rotating shaft is arranged in the first shaft hole; and the limiting block is arranged in the preset hole. When the discharging tool rotates around the first rotating shaft, the limiting block is separated from the preset hole to enter a limiting hole so as to limit movement of thedischarging tool. And the driving lever pushes the start switch to realize the discharging function. According to the embodiment of the invention, during the discharge process, only the discharging tool needs to be rotated and the limiting block of the discharging tool enters the limiting hole formed in the housing to realize discharging, so that the operation becomes convenient. Since the discharging tool is arranged in the housing and is pivoted to the housing, the discharging tool missing is avoided. The alarm device reaching the full service life also can carry out discharging normally toprevent accident occurrence.

Description

technical field [0001] The invention belongs to the field of security technology, in particular to an alarm. Background technique [0002] An alarm is an electronic product that reminds or warns us that we should take certain actions in the form of sound, light, air pressure, etc. in order to prevent or prevent the consequences of an event. Alarms are divided into mechanical alarms and electronic alarms. With the advancement of science and technology, mechanical alarms are more and more replaced by advanced electronic alarms, which are often used in the fields of system failure, safety precautions, transportation, medical rescue, emergency relief, induction detection, etc., closely related to social production. Inseparable. [0003] When the life of the alarm expires and is discarded or recycled, if the built-in battery, especially the lithium battery, still has remaining power, in order to prevent accidents, the remaining power should be discharged. And the alarm on the ...
