Abstract
The utility model relates to an anti-theft alarm device, particularly an anti-theft alarm which is controlled by cipher switches. The utility model is composed of an alarm system, a trigger switch, a box body, the cipher switch, a pressure switch and another cipher switch, wherein, one cipher switch is connected between the alarm system and the trigger switch in series, and the pressure switch and other cipher switch are arranged on the box body. The utility model has the advantages that the simple structure is realized, the alert position can be optionally changed by the cipher switch, the high accuracy and the high sensibility are realized, and the convenient use is achieved. Because the cost of the utility model is low, the usage of the window, the door and the lock catch of the original structure is not influenced when the utility model is installed.
Description
The utility model relates to burglar alarm, especially a kind of burglar alarm that adopts cipher switch control.
Can discern owner's burglar alarm in the prior art, common employing is leaned on mechanical lock or electronic password lock to combine with warning device and is realized.The former can make alarm lose anti-theft alarm function because of key loss or stealer preparation key etc.; Latter's structure is very complicated, and cost is expensive, uses inconvenience, therefore is difficult to apply.
The purpose of this utility model is the deficiency that exists at above-mentioned burglar alarm, and the reliable and practical cipher switch control burglar alarm that a kind of structure is very simple, can accurately discern house-owner people or non-house-owner people is provided.
The utility model cipher switch control burglar alarm comprises warning system, trigger switch and box body, it is characterized in that: go here and there at least between warning system and the trigger switch and adorn a cipher switch; Be used to install the cipher switch that pressure switch is housed on the box body of warning system and can be used with pressure switch.
The utility model cipher switch control burglar alarm can be installed in outdoor or indoor according to different fields of employment, and the cipher switch on the alarm lid matches with pressure switch and can prevent any unlatching or the destruction of alarm box body effectively; Trigger switch and cipher switch that the lead-in wire of alarm will be arranged on door or the window are connected, when cipher switch is arranged on non-alarm condition, trigger switch is inoperative, in case cipher switch is arranged on the warning position, trigger switch and alarm promptly constitute path, under this situation, anyly make the behavior of alarm short circuit all can impel alarm equipment alarm, promptly open door or the window that trigger switch is housed or cut off the alarm lead-in wire and all can report to the police.
The utility model is simple in structure, and cipher switch can arbitrarily change the warning position, and accuracy and highly sensitive is extremely easy to use, applied widely, because this alarm cost is low, it installs the use that does not influence original structure door and window and snap close, and institute is so that promote.
Concrete structure of the present utility model is provided in detail by the following drawings and embodiment.
Fig. 1 is the alarm structural representation.
Embodiment: can be clear that from Fig. 1 cipher switch control burglar alarm is made up of warning system (1), box body (2), trigger switch (3) and cipher switch (4), warning system (1) is installed in the box body (2), string dress trigger switch (3), (5) respectively between the lead A and B of the warning system (1) of drawing from box body (2), between B and the C, each trigger switch (3), (5) all are fitted with cipher switch (4), (7); Pressure switch (6) is housed between box body (2) and the lid, and box body (2) is provided with the cipher switch (15) whether a may command pressure switch (6) works.Warning system (1) is by loudspeaker (8), controllable silicon (9), capacitor (10), resistance (11), (12), (13), and battery (14) is formed.The trigger switch of present embodiment (3) is normally closed magnetic control dry-reed tube switch, and trigger switch (5) is for often opening the magnetic control dry-reed tube switch; Cipher switch (4), (7), (15) are the rotation shunting switch.Cipher switch (4), (7), (15) go back the power available tap changer or waver is made.
The installation of this alarm and the course of work: proceed from the reality, for ease of people's monitoring and strick precaution, can place the box body (2) that warning system (1) is housed outdoor, because the lid of box body (2) is provided with pressure switch (6), open the lid and will trigger warning, therefore, non-owner just can't take the deenergization way to remove warning, three lead A, B that draw from box body (2), C also can be impelled warning if cut off or short circuit.Box body (2) is gone up the cipher switch (7) that is provided with and is designed for battery in owner's maintenance or the replacing box body.Usually cipher switch (4) and (7) of this alarm are installed in outside the door, trigger switch (3), (5) are installed in the side seam place of door, window, when cipher switch (4), (7) are in the warning position, in case door or window are opened, can cause trigger switch (3) or (5) closure, the resistance (12) of warning system this moment (1) provides controllable silicon (9) trigger currents, makes controllable silicon (9) conducting, and loudspeaker (8) energized gives the alarm.Because the conducting electric current is greater than keeping electric current, so even break trigger switch (3) or (5), loudspeaker (8) is still reported to the police.
Claims (3)
1, the utility model relates to burglar alarm, especially a kind of employing cipher switch control burglar alarm, form by warning system (1), box body (2), trigger switch (3), it is characterized in that: go here and there at least between warning system (1) and the trigger switch (3) and adorn a cipher switch (4), be used to install between the box body (2) of warning system (1) and the lid pressure switch (6) is housed, box body (2) is provided with the cipher switch (15) whether a may command pressure switch (6) works.
2, cipher switch control burglar alarm according to claim 1, it is characterized in that warning system (1) draw between lead A and the B, string dress trigger switch (3), (5) respectively between B and the C, each trigger switch (3), (5) all are fitted with cipher switch (4), (7).
3, cipher switch control burglar alarm according to claim 1 and 2 is characterized in that cipher switch (4), (7), (15) are rotation shunting switch or voltage regulation of electric power sources switch or waver.
