Falling-into-water alarm device based on double positioning

Abstract

The invention discloses a falling-into-water alarm device based on double positioning, and the device comprises a device body, one side of the device body is movably provided with a test button display lamp, the surface of the outer wall of the device body is movably sleeved with a starting sleeve, and one side of the starting sleeve is fixedly provided with an outer sleeve locking button. A starting switch is movably mounted in the starting sleeve; through the designed side face protection sleeve and annular protection ring, when the outer wall of a connecting block collides with other substances in the using process of the device body, the annular protection ring pushes a movable sleeve to move towards the outer wall of the side face protection sleeve along the outer wall of a limiting rod at the moment, and a movable spring is extruded in the moving process; when the movable spring is extruded, rebounding force can be formed and counteracts impact force generated by the outer wall,the section of an existing annular protection ring is round, the impact force on the periphery of the outer wall of the side face protection sleeve can be counteracted, and the problem of protection of the connecting block is solved.

Description

technical field [0001] The invention belongs to the technical field of alarm devices, and in particular relates to a water-fall alarm device based on dual positioning. Background technique [0002] An alarm device is an information display device that indicates the occurrence of a malfunction, accident or dangerous situation. According to the characteristics of the code used and the nature of the sensory channel for receiving information, it can be divided into visual alarms, auditory alarms, tactile alarms and olfactory alarms. Its design requirements: the obvious alarm signal has sufficient strength, which is easy to cause people's involuntary attention, or has obvious specificity in characters. [0003] An antenna slot is opened on one side of the existing water alarm device, and the antenna can be limited to the inside through the antenna slot, so that it can be used easily. However, when the existing device falls into the water, the antenna cannot be removed from the a...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a dual-positioning-based water-falling alarm device to solve the above-mentioned background technology. The antenna slot can be used to limit the antenna inside, so that it is easy to use, but when the existing device falls into the water, the antenna cannot be taken out from the inside of the antenna slot in time, so that the signal cannot be sent in time. When the work efficiency will decrease and the safety will decrease
