Abstract
The utility model relates to an automatic alarm circuit switch mechanism, which comprises a microswitch arranged on a supporting rack. The utility model is characterized in that the supporting rack is provided with a glide bolt, wherein, the end face of the glide bolt is connected with a pressure spring in series; the periphery of the glide bolt is provided with a cylindrical face for triggering a rocking handle to be in a closed state; the cylindrical face is provided with a cambered concave part for containing a small turning wheel of the rocking handle so that the rocking handle are kept expanded; a signal triggering traction line is connected with the middle part of one end of the slide bolt; the traction direction of the traction line is opposite to the acting force direction of the pressure spring to the slide bolt. When the traction line is triggered or cut, the microswitch is in a switching state.
Description
The utility model relates to a kind of automatic alarm circuit switching mechanism.
Existing warning circuit is usually by sensor-triggered work such as infrared ray or microwaves, and the shortcoming of existence mainly is: these transducers cost an arm and a leg, and be interfered (as scurrying into or variations in temperature of toy) easily produces false alarm.
The purpose of this utility model is that a kind of automatic alarm circuit switching mechanism will be provided, its simple structure, and cost is low.
The utility model is to constitute like this, it comprises is located at the sensitive switch in order to be connected with warning circuit on the locating support, it is characterized in that: 1) support is provided with one end and a distortion stage clip is connected in series and is subjected to stage clip distortion to recover the sliding bolt of elastic force effect mutually, sliding bolt outer periphery has the little runner in order to touch switch rocking handle termination to make rocking handle be in the face of cylinder of closure state, the face of cylinder is provided with in order to hold the little runner of rocking handle, so that the sensitive switch rocking handle keeps open arc-shaped depression portion, 2) have an alarm signal to trigger draught line and be connected with the centre of sliding bolt one end, the tractive effort direction of this draught line is opposite to the force direction of sliding bolt with stage clip.
When the burglar invades and harasses and when touching draught line, make through arc-shaped depression portion and junction, the back segment face of cylinder and put on the rocking handle thereby sliding bolt recovers under the effect of distortion elastic force slippage forward at stage clip, sensitive switch is in switching state.
When the burglar cut off draught line, sliding bolt recovered slippage forward under the effect of distortion elastic force at stage clip, put thereby make on the rocking handle through arc-shaped depression portion and junction, the leading portion face of cylinder, and little switch is in switching state.
Switching mechanism of the present utility model only adopts sensitive switch, stage clip, and cheap parts such as sliding bolt and draught line constitute, and therefore simple in structure, cost is low.
Below in conjunction with drawings and Examples the utility model is specifically described.
Fig. 1 is the embodiment working state schematic representation.
Fig. 2 is embodiment alarm condition one schematic diagram.
Fig. 3 is embodiment alarm condition two schematic diagrames.
With reference to accompanying drawing, the utility model embodiment comprises and is located at the sensitive switch 2 in order to be connected with warning circuit on the locating support 1, it is characterized in that: 1) support is provided with one end and a distortion stage clip 3 is connected in series and is subjected to stage clip distortion to recover the sliding bolt of elastic force effect mutually, sliding bolt outer periphery has the little runner in order to touch switch rocking handle termination to make rocking handle be in the face of cylinder 4 of closure state, the face of cylinder two is provided with in order to hold the little runner of rocking handle, so that the sensitive switch rocking handle keeps open arc-shaped depression portion 5,2) have an alarm signal to trigger draught line 6 and be connected with the centre of sliding bolt one end, the tractive effort direction of this draught line is opposite to the force direction of sliding bolt with stage clip.
Above-mentioned sliding bolt front end is provided with the thin axle 7 that passes a shaft bearing plate, and compression spring sleeve is on thin axle, and stage clip one end heads on shaft bearing plate 8, and other end item the front end face of sliding bolt.
The utility model is novel, and is reasonable in design, and result of use adopts the alarm that this switching mechanism makes well, and not only cost is low but also reliable operation.
