Abstract

The utility model relates to an automatic calling alarm for door-prizing, comprising a civil alarm lock and a motor. The utility model is characterized in that the automatic calling alarm also comprises a self-locking drive mechanism; an arm spring on an automatic dialing wheel of the mechanism instantly press a preposed barrier chip of a self-locking switch K2; a gear of the automatic dialing wheel is engaged with a gear of the drive mechanism. The utility model does not alarm when a door is normally opened, but only alarms families with pagers under the condition that the door is pried or crashed open. The utility model has the advantages of simple structure, large application range, low cost, strong adaptability, etc.

Description

The automatic paging alarm of forcing open the door

The utility model relates to a kind of alarm lock, especially a kind of automatic paging alarm of forcing open the door.

The existing warning device of using costs an arm and a leg, and structure is also very complicated, and use of general inapplicable family and the chimes of doom that sends when having the people to steal can not transmit alerting signal to the distant place.Though Chinese patent 9424916 is introduced and a kind ofly can be sent alarm sound when having the people to force open the door, can send the anti-theft alarm lock of alerting signal again to remote receiver, but the alarm range of this alarm lock there is limitation, uses extensive inadequately, the volt capping is little, is difficult for implementing.

The automatic paging alarm of forcing open the door that provides a kind of and civilian Alarm lock to be used is provided the purpose of this utility model, it can reach at the normal switch door does not report to the police, only forcing open the door or hitting under the situation of door, to there being the household who carries beeper to send the purpose of alerting signal.

The purpose of this utility model is achieved in that it comprises civilian Alarm lock, motor, it is characterized in that: it also has a self-locking gear train, preposition catch moment of arm spring on the automatic dialing wheel of this mechanism and self-lock switch K2 presses, automatically the gear of dialing wheel and the gearing mesh of gear train; Connect with K switch 2 after the normally opened contact J1 parallel connection of K switch 1 and relay J, the normally opened contact J2 of relay J connects with motor, and constitutes the loop with power supply, and described automatic dialing wheel has two above perform regions, also there are two above perform regions its below, and the perform region is corresponding up and down; Described gear train is the worm and wormwheel reduction gear.

The utility model has the advantages that: simple in structure, dependable performance, the volt capping is big, can the multi-door warning of a machine, can both monitor throughout the country whether the door has situations such as stolen, low cost, applicability is big.

Concrete structure of the present utility model is provided by the following drawings and embodiment.

Fig. 1 is a fundamental diagram of the present utility model.

Fig. 2 is the dialing wheel perspective view in the utility model.

Fig. 3 is a circuit diagram of the present utility model.

Wherein: 1, telephone set 2, telephone set six core leads 3, phone six core plugs 4, telephone set 6-pin socket 5, telephone terminal distribution board 6, preposition catch 7, perform region 8, dialing wheel 9, arm spring 10, gear train 11, motor 12, charging socket 13, tapered end microswitch K1 lead-in wire 14, hands-free K switch 3 lines 15 of phone, the phone memory redials K switch 4 lines 16, phone house lead in 17, civilian Alarm lock 18, self-lock switch K2 line 19, perform region 20, gear

With reference to accompanying drawing as can be known, the utility model comprises civilian Alarm lock (17), motor (11), it is characterized in that: it also has a self-locking gear train (10), preposition catch (6) moment of arm spring (9) on the automatic dialing wheel (8) of this mechanism and self-lock switch K2 presses, automatically the gearing mesh of the gear (20) of dialing wheel (8) and gear train; Connect with K switch 2 after the normally opened contact J1 parallel connection of K switch 1 and relay J, often the opening of relay J touched J2 and connected with motor, and constitutes the loop with power supply, and described automatic dialing wheel (8) has two above perform regions, also there are two above perform regions its below, and the perform region is corresponding up and down; Described gear train is the worm and wormwheel reduction gear.

When mounted, known civilian Alarm lock (applicant applies for a patent to Patent Office of the People's Republic of China) is screwed on timber or iron gate, a microswitch K1 is arranged in the civilian Alarm lock, wherein the plug of K switch 1 is inserted on the socket of the utility model alarm, after the safety lock of door is locked, K switch 1 is in warning state to be closed, run into this moment forces open the door or hits door, warning spring in the civilian Alarm lock departs from the gear wheel on the doorframe, under the elastic force of warning spring, eject, this moment, the K1 microswitch was closed by the moment compressing, relay J 1 normally opened contact is by instantaneous short circuit, electric current is through the relay coil loop, the relay adhesive is started working, another road constitutes the loop through J2 normally opened contact and motor, motor is started working, mechanical transmission mechanism is also started working, motor shaft coupling worm screw gives worm-gear toothing conjuncted transmission of torque with 2000 rev/mins speed, because the rotating ratio of worm and wormwheel is 1: 20, thereby the conjuncted per minute of worm-gear toothing to obtain rotating speed be 100 to change, gear is given the gear of the next stage number of teeth greater than 7 times of the numbers of teeth own with the rotating speed that per minute 100 changes with transmission of torque, the Revolution Per Minute 14 that this one-level is obtained changes, this gear also is that size is conjuncted, pinion wheel is given the gear of the next stage number of teeth greater than 7 times of the numbers of teeth own with the rotating speed that per minute 14 changes with transmission of torque, make the rotating speed of this one-level reduce to per minute 2 commentaries on classics, the gear of this one-level also is that size is conjuncted, thereby pinion wheel is given the dialing wheel gear of the afterbody number of teeth greater than 2 times of the numbers of teeth own with the rotating speed that per minute 2 changes with transmission of torque again, because dialing wheel and dialing wheel gear are conjuncted, thereby the rotating speed that dialing wheel is finally obtained is that per minute 1 changes, dialing wheel changes this circle and finishes three automatic paging dialing, the working time of three dialing and each the dialing interval time, the 2 seconds zones that lag behind all are arranged on the cylindrical structure of dialing wheel.

In sum, because home telephone is by the wired transmission of post and telecommunications office, so reliability is relatively good, and the volt capping is bigger, but the user should self have beeper, and your beeper volt capping is much, and the volt capping effect of this machine also just has much.And must lock the safety lock on the door, otherwise this machine is invalid.
