Certainly it will be understood by those skilled in the art that colour code also can be set directly on circuit board assemblies 20 in the embodiment that circuit board assemblies lid 30 is not set, the user can observe by transparent apertures 42 variation of color equally.
Manual alarm device can also comprise a upper cover 60, and upper cover 60 can link together with base 10, and the circuit board assemblies 20 in manual alarm device, circuit board assemblies lid 30 and operating parts 40 etc. are covered in the space that upper cover 60 and base 10 limit.The middle part of upper cover 60 is provided with a window 62 that can supply pressing operation spare, and can observe from window 62 warning and the monitor state that the transparent apertures 42 on operating parts 40 shows.The user can observe by transparent apertures 42 and window 62, when seeing colour code 32, illustrates that manual alarm device is in alarm condition.
The course of work of manual alarm device of the present invention is described in conjunction with Fig. 4 to 6 now.
Fig. 4 has shown that manual alarm device is in the schematic diagram under monitored state, and at this moment, the contact element 46 on operating parts 40 contacts with the switch element 24 of circuit board assemblies.When needs were reported to the police, the operator was along the direction push spare 40 of pressing shown in Figure 4, and operating parts 40 will rotate around aixs cylinder 44 this moment, go to position shown in Figure 5.
As shown in Figure 5, the operator by depressing, grab 18 (referring to Fig. 2) on operating parts 40 and base 10 breaks away from, operating parts 40 has been broken away from the constraint of grab 18, operating parts 40 is take aixs cylinder 44 as axle towards the direction rotation of base 10, elastic component 14 on base 10 is compressed at this moment, and operating parts 40 slides along triggering direction shown in Figure 5 under the effect of the elastic force of keeper 50 (referring to Fig. 2).
At this moment, contact element 46 beginnings on operating parts 40 break away from switch element 24, and when the moment that contact element 46 and switch element 24 break away from fully, manual alarm device sends alerting signal.Finally as shown in Figure 6, the aixs cylinder 44 of operating parts 40 is moved along guide rail 12.While is along with the end of operator presses effect, under the effect of the elastic restoring force of elastic component 14, operating parts 40 is take aixs cylinder 44 as axle, court is the direction rotation of base 10 dorsad, turn to the residing same plane of the monitor state of operating parts 40 in (namely with same plane shown in Figure 4 on), manual alarm device is completed the conversion from the monitored state to the alarm condition.
An embodiment in conjunction with manual alarm device shown in Figure 3, when operating parts 40 is in alarm condition, transparent apertures 42 on operating parts 40 moves to the top of the colour code 32 of circuit board assemblies lid 30 just, at this moment, the user can see through window 62 and the transparent apertures 42 on upper cover 60, observe the colour code 32 on circuit board assemblies lid 30, thereby confirm that manual alarm device has been in alarm condition.
Return referring to Fig. 4, switch element 24 contacts with contact element 46 under monitored state; After push spare 40, referring to Fig. 6, switch element 24 separates with contact element 46, and manual alarm device gives the alarm.Those skilled in the art also can adopt another kind of design proposal, and namely switch element separates with contact element under monitored state, and after push spare, switch element contacts with contact element 46, and manual alarm device gives the alarm.
When using under the higher environment of temperature, creep easily occurs in operating parts, and the direction of creep is usually parallel with the direction that operating parts is pressed.In manual alarm device of the present invention, during warning, operating parts presses perpendicular direction in the triggering direction of switch element, even therefore on the direction of pressing of operating parts, creep occurs, can not cause that switch element is subjected to displacement on its triggering direction yet, thus the spurious alarm of effectively having avoided manual alarm device at high temperature to occur.
In addition, in the process from the monitor state to the alarm condition, operating parts not only rotates take aixs cylinder as axle, also produce simultaneously mobile, after operating parts is completed actuation of an alarm, can be returned to the residing same plane of monitor state on, make manual alarm device of the present invention have good dust and water protection characteristic.
Due to the circuit board assemblies lid of manual alarm device of the present invention, operating parts and on cover colour code, transparent apertures and window be set respectively, like this when manual alarm device is in alarm condition, colour code, transparent apertures and window can be mutually stacked, determine the residing state of manual alarm device in order to the user.
The above only is the schematic embodiment of the present invention, is not to limit scope of the present invention.Any those skilled in the art, the equivalent variations of doing under the prerequisite that does not break away from design of the present invention and principle, modification and combination all should belong to the scope of protection of the invention.
