Embodiment
Enumerate following preferred embodiment and conjunction with figs. below, structure of the present invention and effect are elaborated.
As shown in Figure 1 and Figure 2, the starter gear 10 of the burglar alarm that is provided for the present invention's first preferred embodiment, starter gear 10 includes a microswitch 20, a transmitter 30 and a contact 40.
As Fig. 2, shown in Figure 3, microswitch 20 has a body 22, a moving part 24, an elastic component 26 and a support arm 28.Body 22 is fixed in a doorframe 52, and a side of body 22 has a perforate 221.One end of moving part 24 is hubbed at body 22, makes moving part 24 body 22 pivots pendulum relatively, and the lateral surface of its other end has 242, two ears 242 of two ears, and to pass perforate 221 outwards outstanding.As shown in Figure 3, the medial surface of the body 22 and moving part 24 other ends is replaced at the two ends of elastic component 26 respectively.Support arm 28 has two pivot connecting plates 282, one end of two pivot connecting plates 282 is articulated in two ears 242 of moving part 24, make support arm 28 moving part 24 pivots relatively, but the other end of two pivot connecting plates 282 then is articulated with the roller 284 of original place rotation, in addition, support arm 28 has a catch 286, and the dual-side of catch 286 connects a side of two pivot connecting plates 282 respectively, but block only can pivot support arm 28 towards a single direction in moving part 24 when catch 286 pivoted at support arm 28.
Contact 40, have a fixed part 42, a junction 44 and a touch part 46 in the present embodiment, wherein fixed part 42 is fixed in mobilizable interior door 50 apical margins, make contact 40 can be subjected to the open and close of interior door 50 and move along a first direction and a second direction, one end of connecting portion 44 vertically is connected in the top of fixed part 42, the bottom of touch part 46 then vertically is connected in the other end of connecting portion 44, make touch part 46 be parallel to fixed part 42, and the cross section of contact 40 is L-shaped, and the height of touch part 46 is higher than interior door 50.
Via said structure, as shown in Figure 4, when the past interior opening chamber of thief inside door 50, contact 40 can move along first direction along with interior door 50, at this moment, the roller 284 of support arm 28 will be touched in the touch part 46 of contact 40, makes support arm 28 pushing and pressing moving parts 24, moving part 24 will produce beat, and compression elastic piece 26, thus, microswitch 20 will start transmitter 30, make transmitter 30 emission start signal alarm receivers, the alarm receiver will produce the sound.When thief close chamber inside door 50, contact 40 is for to move along second direction, as Fig. 5, shown in Figure 6, the roller 284 of support arm 28 can be touched in the touch part 46 of contact 40, support arm 28 is pivoted towards single direction, promptly pivot, thus towards direction near body 22, moving part 24 can not pushed against and beat by support arm 28, and transmitter 30 can not started by microswitch 20.
As shown in Figure 7, for the present invention being installed in the state of a mobilizable exterior door 60, microswitch 20 and transmitter 30 are installed in the root edge of a doorframe 62 medial surfaces, contact 40 is installed in the apical margin of exterior door 60 medial surfaces, when exterior door 60 is opened outward, contact 40 can touch microswitch 20, makes microswitch 20 start transmitter 30.
As Fig. 8, shown in Figure 9, be the starter gear 70 that the present invention's second preferred embodiment is provided, its structure and first preferred embodiment are roughly the same, and its difference is:
In the present embodiment, microswitch 72 is installed in an indoor rolling door door pillar 82 with transmitter 74, the support arm 722 of microswitch 72 is sheet iron rolling door 80 in one, and contact 76 be installed in the root edge of sheet iron rolling door 80, and touch part 762 is stretched out by fixed part 764 1 ends of contact 76.
When central sheet iron rolling door 80 scrolls up, contact 76 can up move along with middle sheet iron rolling door 80, and utilize touch part 762 to touch the support arm 722 of microswitch 72, make microswitch 72 start transmitter 74, and central sheet iron rolling door 80 is when closing downwards, and support arm 722 also can down be touched in the touch part 762 of contact 76, and support arm 722 is pivoted downwards, thus, transmitter 74 can not started by microswitch 72.
In addition, contact 76 also can be used the form of first preferred embodiment instead, makes the gap between touch part 762 and the support arm 722 less, and the movable distance of sheet iron rolling door 80 shortens in making, and increases the sensitivity of burglar alarm.
As shown in figure 10, be the starter gear 90 that the present invention's the 3rd preferred embodiment is provided, its structure and above-mentioned two preferred embodiments are roughly the same, precisely because difference is:
In the present embodiment, but starter gear 90 lands aluminium door 100a, 100b for what be installed in two move left and right, wherein microswitch 92 and transmitter 94 are installed in and land aluminium door 100b apical margin, and the support arm 924 of microswitch 92 is towards the top, contact 96 then is installed in and lands aluminium door 100a apical margin, and the touch part 962 of contact 96 is vertically extended by fixed part 964 1 ends of contact 96.
When landing aluminium door 100a when being drawn back toward left side or turn right, support arms 924 can be touched in the touch part 962 of contact 96, make microswitch 92 start transmitters 94.
Therefore, starter gear of the present invention can be installed in door miscellaneous, makes the present invention have quite high elasticity and practicality.And, because the touch part of contact and the arm room of microswitch have a segment distance, even contact is close towards the support arm direction, as long as contact does not promote moving part via support arm, just can not touch transmitter at once, avoid disturbing people's sound because of the burglar alarm generation suddenly at closing time of going out.Also, make and grow serviceable life of the present invention, be difficult for breaking down because the support arm and the moving part of microswitch are mechanical component.
In addition, microswitch of the present invention also can utilize electric wire to connect microswitch and transmitter except starting the transmitter with wireless signal, makes microswitch directly start transmitter by electric wire.
