Description
[technical field]
The utility model relates to a kind of safety alarm device, specifically, is a kind of audible-visual annunciator.
[background technology]
The place needing at all types of industries equipment at present is all provided with safety alarm device.Wherein, audible-visual annunciator has a wide range of applications especially, but most audible-visual annunciator small product size having come into operation is large, needs more metal material, heaviness, and power is large, is unfavorable for on-the-spot installation, and energy consumption is high; The non-Integral design of installation foot, yielding under strong motion, fracture, gets loose; It is selective that product does not possess multiple warning tone, and range of application is wide not.Alarm sound is loud not, is unfavorable for field adjustable and selects, and alarming effect difficulty reaches ideal effect; Adopt halogen light source, compare LED light source power consumption and want large, shorter, poor seismic behavior of life-span; In alarm, without the terminal for terminal block, be generally extension line, do not meet commercial unit installation requirement, have potential safety hazard; The warning lamp state of warning mostly is rotating light or blink states is not strong to visual impact, does not have obvious warning effect.
The audible-visual annunciator of being convenient to install about a kind of good warning effect of the present utility model, energy-saving safe yet there are no relevant report.
[summary of the invention]
The utility model has overcome deficiency of the prior art, and a kind of good warning effect is provided, and energy-saving safe is convenient to the audible-visual annunciator of installing.
A kind of audible-visual annunciator, be provided with housing, lampshade, wiring cover plate, pcb board assembly, lamp plate assembly, piezoelectric loudspeaker and back shroud, described lampshade is screwed on housing, described wiring cover plate is screwed on housing, described lamp plate assembly is screwed on pcb board assembly, and described piezoelectric loudspeaker is screwed on housing, and described back shroud is screwed on housing, described lamp plate assembly adopts LED light source, the integrated 32 kinds of tones of described piezoelectric loudspeaker.
Described housing is provided with installation foot.
In the middle of described housing and lampshade, by O RunddichtringO, seal.
Between described piezoelectric loudspeaker and housing, by O RunddichtringO, seal.
Between described back shroud and housing, by sealing strip, seal.
Described wiring cover plate is provided with connection terminal.
Described lamp plate assembly and pcb board assembly are fixed on housing jointly.
The utility model advantage is:
1. small product size is little, lightweight, and power is little energy-conservation, is convenient to on-the-spot installation, uses.
2. installation foot integral type design, intensity is better, more reliable.
3.32 kinds of tones are integrated, and the scene of being convenient to is selected and debugged;
4. adopt superbright emitting led, brightness is high, good warning effect, long service life;
5. in alarm, adopt connection terminal wiring, meet commercial unit installation requirement, safety is high.
6. the warning lamp state of warning adopts and repeatedly connects fast sudden strain of a muscle state, and visual effect is strong, can play better alarming effect.
[accompanying drawing explanation]
Accompanying drawing 1 is the structural representation of a kind of audible-visual annunciator of the utility model.
Accompanying drawing 2 is that a kind of audible-visual annunciator of the utility model is along the cut-open view of A-A line in Fig. 1.
The Reference numeral and the ingredient that in accompanying drawing, relate to are as follows:
1. housing 2. lampshades
3. screw 4. wiring cover plates
