Abstract
The utility model discloses a theft proof alarm of a theft proof door, which substantially aims at the defect that at present the structure of a theft proof doorbell is complex and the costs is high. The utility model provides the solution scheme that both ends of a button switch of an ordinary door bell are additionally and parallel connected with a set of tumbler switches and micro-active switches, which are connected in series, and the micro-active switches are arranged on a folding of a vertical edge of the theft proof door. When a door is closed, the micro-active switches are extruded, thereby the tumbler switches and the micro-active switches are in an off state, when the door is opened, the micro-active switches are released to be in an original state, and thereby the tumbler switches and the micro-active switches are in a communicated state. The micro-active switches arranged on the folding of the vertical edge of the theft proof door and the tumbler switches are capable of being disconnected or communicated through closure action of the theft proof door, thereby playing roles of theft proof alarming and retaining an original doorbell. Therefore, the utility model has the advantages of simple structure, convenient installment, and economy and reliability.
Description
Technical field
The utility model relates to a kind of burglar alarm, particularly relates to a kind of antitheft door burglar alarm.
Background technology
Continuous development along with national economy, improving constantly of living standards of the people, people have taken leave of one-storey house, tube-shaped apartment gradually, have moved into the residential quarters of house not sharing an entrance with others successively, therefore residents' security protection consciousness is also strengthened thereupon, a fan antitheft door is installed has been become a requisite fitting-out work.Yet antitheft door has been installed, but can not have been put things right once and for all, the lawless person still can adopt some means that door is opened, and enters the room to rob case and also happen occasionally, and how can more effectively reduce the problem that potential safety hazard, the measure of improving the precaution have become people further to pay close attention to.In recent years, also occurred some on the market and be installed in theft-proof door bell on the antitheft door, but existed some problems: (1) when antitheft door cuts out the crack between a door and its frame gap little, accuracy requirement height, thereby be easy to generate the wrong report phenomenon; (2) have the mechanical hook-up of the function of closing the door automatically, allow the people shut the door accidentally easily and with thing particularly key dropped on family; (3) structure is comparatively complicated, and cost is higher.
Summary of the invention
The purpose of this utility model is exactly at the above-mentioned defective that exists in the prior art, and a kind of simple in structure, easy for installation, with low cost, antitheft door burglar alarm of being not easy to produce the wrong report phenomenon is provided.
The utility model is realized by the following technical solutions: this antitheft door burglar alarm, comprise a doorbell, be parallel with the toggle switch and the microswitch of one group of series connection in addition at the pushbutton switch two ends of this doorbell, described microswitch is installed in stile folding place of antitheft door, when door is closed, microswitch is squeezed and makes toggle switch and microswitch be in off-state, and when door was opened, microswitch was released back former and makes toggle switch and microswitch be in UNICOM's state.
Because the utility model adopts is will be installed on doorbell on the antitheft door by inserting a toggle switch and a microswitch converts, closed action by antitheft door makes and is installed on a microswitch of stile folding place and toggle switch disconnects or UNICOM, the effect that can reach burglar alarm has like this kept the effect of former doorbell again, therefore simple in structure, easy for installation, economic and reliable.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
In the circuit theory diagrams of embodiment as shown in Figure 1, button switch K 1 two ends of doorbell are parallel with the toggle switch K2 and the microswitch K3 of one group of series connection in addition, microswitch K3 has two contacts, on the circuit control panel 1 that is connected to doorbell, another is received on the toggle switch K2, microswitch K3 is installed in stile folding place of antitheft door, when door is closed, microswitch is squeezed and makes toggle switch and microswitch be in off-state, when door was opened, microswitch was released back former and makes toggle switch and microswitch be in UNICOM's state.When sleeping and door is closed when resident family, this moment, microswitch K3 and toggle switch were in off-state, when the guest is visiting, pin button switch K 1, doorbell circuit is connected, and loudspeaker 2 sound, burglar alarm is as the usefulness of common doorbell at this moment, when preventing normal door, microswitch K3 and toggle switch UNICOM and report to the police should disconnect toggle switch K2 this moment; When resident family prepares to fall asleep, Closing Switch K2, if there is the uninvited guest that door is opened like this, microswitch K3 discharges back former, and toggle switch K2 is communicated with microswitch, and this moment, loudspeaker 2 sounded, and had so just reached the effect of burglar alarm.
Burglar alarm from the utility model is out of shape out, principle is identical is converted by wireless doorbell also belongs to protection domain of the present utility model.
