Abstract

The utility model belongs to a vibration awakening device, mainly for the safe emergency alarm of the deaf, which chiefly comprises a foundation plate, a transmission rope, a trigger and a striking hammer, wherein a hammer handle and a hammer head are elastomers, one end of the hammer handle can be connected with the foundation plate through a fixed pin. The foundation plate of the utility model is nailed on the bottom of a bed board. When used, the trigger rotates under the actions of a backdraught device. The opened striking hammer returns quickly, hits the foundation plate again and again and then produces vibration, which attains the objective of awakening the deaf. The utility model is not controlled by the circuit, with simple structures and safe and convenient usage and without the influence of current failure.

Description

The watchful device of deaf person's safe emergency

Technical field

The utility model belongs to vibration and wakes device, mainly is that to be used for deaf person's safe emergency watchful.

Background technology

Existing deaf person wakes device, mainly contains vibrations and wakes device (CN92201247.4) and the deaf person wakes device (CN93207702.8), and wake device for these two kinds and all adopt circuit control device, complex structure, and be difficult to play a role after running into the emergency condition power failure.

Summary of the invention

The purpose of this utility model provides a kind of watchful device of deaf person's safe emergency simple in structure, easy to use.

The technical scheme that its technical matters that solves the utility model adopts is: it comprises substrate and transmission rope, substrate is provided with trigger, this trigger flexibly connects by stationary shaft and substrate, trigger is provided with returning device, trigger one end and transmission rope join, be provided with substrate is fastenedly connected at the sidepiece of trigger and impact hammer, its hammer handle and tup are elastic body, and hammer handle one end joins by fixed pin and substrate.

The beneficial effects of the utility model are: substrate nail of the present utility model is in the bed board bottom, join with the bed body is fastening, during use, the trigger on the substrate can rotate on base plan under returning device and transmission rope effect, when the long limit of trigger with to impact hammer handle axial when vertical, be located at the hammer that impacts of trigger sidepiece, because its hammer handle is an elastic body, impact hammer handle and open with substrate in a certain angle this moment, unclamp transmission rope, the trigger rotation under the elastic force effect, impacts the rapid return of hammer and hits large substrates repeatedly, produce vibrations, reach the purpose of waking up with a start the deaf person, need not control by circuit, simple in structure, safe and convenient to use, not being subjected to have a power failure influences.
