Design method, although extensive utilization has been commercially available, it is in some special dimensions in use, manual fire report
After prolonged use, mechanical trigger mechanism thereon will appear that aging, reaction speed is slack-off, gets rusty, corrodes to alert switch
Problem largely affects the use of manual fire alarm switch, increases security risk.
Therefore, the warning triggering mechanism for designing a kind of manual fire alarm switch, solves machine in traditional manual alarm button
Aging existing for tool trigger mechanism, reaction speed is slack-off, the problems such as getting rusty, corroding, to those skilled in the art right and wrong
Often it is necessary to.
Utility model content
The purpose of this utility model is to provide a kind of warning triggering mechanisms of manual fire alarm switch, instead of traditional machine
Tool trigger switch solves to be easy to appear aging, reaction in traditional manual alarm button after mechanical trigger mechanism long-time use
The problems such as slowing, get rusty, corroding.
To achieve the above object, the technical solution adopted in the utility model is as follows:
A kind of warning triggering mechanism of manual fire alarm switch, including for being mounted in alarm switch, can be by alarming
The button pressing board of switch drives mobile light-blocking block, and the U-shaped optoelectronic switch for being mounted in alarm switch；The U
Type optoelectronic switch includes that notch and light-blocking block match, so that the U-type groove and infrared emission that light-blocking block can move in notch
Device and infrared remote receiver；The corresponding two sides of the U-type groove notch inner wall offer a placing groove, the infrared transmitter and
Infrared remote receiver one-to-one correspondence is mounted in two placing grooves, and infrared transmitter and infrared remote receiver are associated with alarm switch
Circuit board in be used as switching signal feedback element, with infrared signal whether by light-blocking block block realize alarm switch open and close shape
The control of state.
Compared with prior art, the utility model has the following beneficial effects:
The utility model devises light-blocking block and U-shaped optoelectronic switch, when being applied on manual fire alarm switch, passes through
The mode of optoelectronic induction, solve traditional manual fire alarm switch using the existing aging of mechanical trigger mechanism operation,
Reaction speed is slack-off, the problems such as getting rusty, corroding, more severe suitable for using under a variety of application and environments
It is used in environment.The utility model only need to apply pressure to button pressing board when in use, and button pressing board is made to generate displacement, can band
Dynamic light-blocking block is mobile, blocks and separates and is formed by infrared signal optical axis between infrared transmitter and infrared remote receiver, to produce
Raw alarm feedback signal, realizes the effect of manual fire alarm switch alarm, easy to operate, convenient.

Specific embodiment
The utility model is described in further detail with embodiment for explanation with reference to the accompanying drawing, and the mode of the utility model includes
But it is not limited only to following embodiment.
Embodiment
The utility model provides a kind of novel warning triggering mechanism, can be applied on manual fire alarm switch, such as
Shown in Fig. 1, the utility model is mainly made of a U-shaped optoelectronic switch 1 and a light-blocking block 2.Wherein, U-shaped optoelectronic switch 1 includes
The U-type groove 101 and infrared transmitter 102 and infrared remote receiver 103 that notch and light-blocking block match.102 He of infrared transmitter
Relationship between infrared remote receiver 103 and U-type groove 101 specifically: the corresponding two sides of the 101 notch inner wall of U-type groove open up
There is a placing groove, the infrared transmitter 102 and the one-to-one correspondence of infrared remote receiver 103 are mounted in two placing grooves.
The installation and service condition of the utility model is described below.
The utility model is packed into that the state to fire alarm switch is as shown in Figure 4,5,1 He of U-shaped optoelectronic switch
Light-blocking block 2 is installed in alarm switch.Light-blocking block 2 is connect with the button pressing board 4 of alarm switch, light-blocking as shown in Fig. 3,4,5
Block 2 can be driven by button pressing board 4 and be moved.And the U-shaped optoelectronic switch 1, the electricity in U-type groove 101 and alarm switch thereon
Road plate 3 is then fixed on together in the mid-game 5 of alarm switch, and then light-blocking block 2 can be in U-type groove 101 under the drive of button pressing board 4
Notch in move, as shown in Fig. 2,4,5.Also, infrared transmitter 102 and infrared remote receiver 103 on U-shaped optoelectronic switch 1
It is associated in the circuit board of alarm switch as switching signal feedback element, whether realization report is blocked by light-blocking block with infrared signal
The control (can be realized by prior art means) of alert switch open and close state.
After the utility model is installed to manual fire alarm switch above, in use, if without fire alarm, this
When manual fire alarm switch state as shown in figure 4, at this point, due to not to the application pressure of button pressing board 4, thus at this time
Infrared remote receiver 103 can normally receive infrared signal, entire manual fire alarm switch is without carrying out alarm response.When
When encountering fire alarm, user is manually pressed by the button pressing board 4 of alarm switch, at this point, under the drive of button pressing board 4,2 court of light-blocking block
U-type groove 101 notch it is mobile, until block and separate be formed by between infrared transmitter 102 and infrared remote receiver 103 it is red
External signal optical axis (as shown in Figure 5), at this point, infrared remote receiver 103 is due to failing to receive optical signal and to form a fire alarm anti-
Feedback, circuit board 3 are started to work, and manual fire alarm switch is made to carry out alarm response.
The utility model replaces traditional mechanical alarm trigger switch by the design of U-shaped optoelectronic switch and light-blocking block, can
Efficiently solve after the mechanical trigger mechanism long-time use of manual fire alarm switch occur aging, reaction speed it is slack-off,
The problems such as getting rusty.Therefore, it is suitable for popularization and application.
Above-described embodiment is only one of preferred embodiments of the present invention, should not be taken to limit the utility model
Protection scope, as long as the utility model body design thought and mentally make have no the change of essential meaning or profit
Color, it is solved the technical issues of it is still consistent with the utility model, the protection scope of the utility model should all be included in
Within.
