Abstract

The utility model discloses a device for anti-theft alarm lock. It includes: the intelligent house door alarm device comprises a key 2, a signal transfer disk 5, a control component 9, an alarm component 10 and a door magnet 12, wherein a readable memory 1 storing a user password is buried in a handle of the key 2, the control component 9 detects that the output signal of the door magnet 12 has high and low potential changes when the door is opened every time in a defense state, meanwhile, the control component 9 supplies power to the readable memory 1 in the key 2 through a press contact component 4 on the signal transfer disk 5 and a strip-shaped conductor 11 on the key 2 and reads the stored user password, and once the potential of the door magnet 12 changes and the control component 9 does not read the user password, the control component 9 judges that the house door is illegally opened and controls the alarm component 10 to alarm. Thereby the reliability and the security of tool to lock have been guaranteed.

Description

Device for antitheft alarming lock

1, technical field

The utility model relates to a kind of burglar alarm, particularly device for antitheft alarming lock.

2, background technology

Lockset in the known technology generally includes lock body, tapered end and key, the safety of lockset all is vital to the life and the property of resident family, and at present commercially available most of locksets do not have the reliable precautionary measures the lawbreaker during to its illegal technical opening, just reach the strick precaution purpose by the difficulty that increases illegal technical opening.Now commercially available burglar alarm normally at the gate, infrared induction or the magnetic induction locating to be provided with such as window or room triggers warning device, but this type of warning device does not have and takes precautions against lockset by the anti-theft alarm function of illegal technical opening.

3, utility model general introduction

The purpose of this utility model is at deficiency of the prior art, provides a kind of and illegally opened at door, can in time be sent after particularly lockset is caused door to be opened by illegal technical opening the device for antitheft alarming lock of alarm signal.

In order to achieve the above object, the utility model is achieved in that and comprises key 2, signal converting dish 5, Control Component 9, alarm assemblies 10 and door magnetic 12, its special character is to have buried the readable memory 1 that stores user cipher in key 2 handles underground, root at key 2 columns entangles an insulation ring set 3 firm, on insulation ring set 3 circumferential surfaces, axially embed one group of strip electric conductor 11 at a certain distance, the thickness of strip electric conductor 11 is less than the thickness of insulation ring set 3, and the power supply of readable memory 1 just, negative pole all is electrically connected a strip electric conductor 11 separately with the interface that need be connected with Control Component 9.Be fixed on that signal converting dish 5 on the general lockset tapered end end face is made by insulation materials and offer keyhole 6 at the center, each strip electric conductor 11 corresponding installations when contrast is unblanked in the radial position in signal converting dish 5 are pressed for one group and are touched assembly 4, pressure is touched assembly 4 and is made up of pellet shot from a slingshot 7 and elastic body 8, and pellet shot from a slingshot 7 and elastic body 8 are made by the conductive material with certain structural strength.Each pressure touches assembly 4 and door magnetic 12 is electrically connected to Control Component 9 respectively, and Control Component 9 is electrically connected alarm assemblies 10.

The utility model compared with prior art has following good effect:

All buried the readable memory 1 that stores user cipher in the key 2 of each mandate underground, set up defences and have only Control Component 9 after reading user cipher, just to judge when opening the door under the state to open the door at every turn to legal, because of the lawbreaker can't find out user cipher, so go into no matter force open the door or illegal technical opening lockset and go into all controlled assembly 9 and be judged to be forcible entry, thereby control alarm assemblies 10 is reported to the police.Therefore, the utility model has fundamentally solved the defective that prior art can not be guarded against fully to illegal technical opening, has improved the safety and the reliability of lockset.

Fig. 1 is the composition schematic diagram of the utility model structure and circuit.

5, embodiment

Fig. 1 shows an embodiment of the present utility model.Wherein readable memory 1 can be the eeprom memory of serial line interface, the EEPROM of 24CXX series for example, it also can be other readable memory, just require the interface of it and Control Component 9 can not be too many, touch assembly 4 because in corresponding signal converting dish 5 radial positions too much pressure can not be installed.Control Component 9 can be common single-chip microcomputer, also can be other control circuit.Alarm assemblies 10 can be directly or by the sound or audio alert assembly that telephone wire is reported to the police, also can be the tele-alarm assembly of another warning device of remote control.Door magnetic 12 is the tongue tube or the Hall element of a magnetic induction, when the transformation of opening the door or high electronegative potential all should appear in door magnetic 12 output signals at closing time.Because of readable memory 1, Control Component 9, alarm assemblies 10 and door magnetic 12 are prior art, no longer describe in detail here.In key 2 handles, buried the serial line interface eeprom memory 1 that stores user cipher underground.Root at key 2 columns entangles an insulation ring set 3 firm, on insulation ring set 3 circumferential surfaces, axially embed one group of strip electric conductor 11 at a certain distance, the thickness of strip electric conductor 11 is less than the thickness of insulation ring set 3, and the power supply positive and negative electrode of serial line interface eeprom memory 1 and the interface that need be connected with Control Component 9: data wire SDA interface, clock line SCL interface all are electrically connected a strip electric conductor 11 separately.Signal converting dish 5 centers are offered keyhole 6 and are fixed on the tapered end end face of general lockset with screw 13, signal converting dish 5 is made by having certain thickness insulation materials, each strip electric conductor 11 corresponding installations when contrast is unblanked in the radial position in signal converting dish 5 are pressed for one group and are touched assembly 4, pressure is touched assembly 4 and is made up of pellet shot from a slingshot 7 and elastic body 8, pellet shot from a slingshot 7 and elastic body 8 are made by the conductive material with certain structural strength, elastic body 8 can be spring or other elastomeric objects, and pellet shot from a slingshot 7 is pressed because of the elastic strain effect of elastic body 8 and touched on each strip electric conductor 11 of key 2 when unblanking with key 2.Each pressure is touched assembly 4 and is electrically connected to Control Component 9 respectively with door magnetic 12 on the signal converting dish 5, and Control Component 9 is electrically connected alarm assemblies 10.

When the needs warning is set up defences, can make Control Component 9 work by the switch connection power supply, the interface data that is connected to a magnetic 12 is ceaselessly read in Control Component 9 beginnings, open the door each time and Control Component 9 is detected be connected to the high electronegative potential of a magnetic 12 interface data to change, if open the door with legal key 2, Control Component 9 can be given 1 power supply of serial line interface eeprom memory and read the user cipher of storing in the serial line interface eeprom memory 1 by the strip electric conductor 11 that the pressure on the signal converting dish 5 is touched on assembly 4 and the key 2, high electronegative potential transformation appears if Control Component 9 detects the interface data of a magnetic 12, but do not read user cipher simultaneously, just the expression door is illegally opened, and Control Component 9 will be controlled alarm assemblies 10 and implement to report to the police.
