Abstract

The utility model provides an automatic alarm device for a spring lock, comprising inner pins, outer pins, a small pin, a lock core, a lock housing, a spring, and a function-developing module, the small pin is connected with a lead, and after adding an insulation sleeve, is assembled into the lock core with other inner pins, the other lead is connected with the lock housing, finally, each component is connected with a functional circuit after assembly. When an original key is used to unlock, the circuit is not connected, however, when illegal unlocking is performed, the outer pins are in contacts with the lock housing, connecting the circuit, a sound alarm module in a trigger circuit emits alarm sound to remind a master, a camera module shoots appearances of lawless persons. The beneficial effects of the automatic alarm device for a spring lock are: simple structure, convenient installation and operation, good pick-proof identification performance, function module capable of developing according to need, etc.

Description

The cylinder lock autoalarm

Technical field

The utility model belongs to the cylinder lock field in the hardware industry, relates in particular to a kind of cylinder lock autoalarm.

Background technology

Known, the existing lockset overwhelming majority all is a cylinder lock, and the common spring lock does not have automatic warning function, and a people who trains a little often can open common cylinder lock in tens seconds, the method of unblanking also can reach tens kinds, and the instrument of unblanking reaches tens kinds especially.In this case, common lockset anti-theft feature far from.

Existing those high-tech theftproof locks, as fingerprint recognition lock, the lock of swiping the card, recognition of face lock, the costliness of its price is to such an extent as to be difficult to come into ordinary people family.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of cylinder lock autoalarm is provided.

To achieve these goals, but cylinder lock autoalarm of the present utility model form by interior pellet shot from a slingshot, outer pellet shot from a slingshot, little pellet shot from a slingshot, lock core, lock housing, spring, insulation sleeve expanding function module.

Described cylinder lock autoalarm, it is characterized in that: functional module is self-powered, is connected with submissile with lock housing respectively by two leads.At this moment, little pellet shot from a slingshot is with a touch switch on the lock housing forming circuit.

Described cylinder lock autoalarm is characterized in that: the lock core outside has sulculus, lays lead, avoids influencing the normal rotation of lock core.

Described cylinder lock autoalarm is characterized in that: the top of little pellet shot from a slingshot to the marginal distance of lock core lock housing greater than key front portion (after going into lockhole, than the sub-position of submissile more by an inboard part), maximum height difference.

With reference to accompanying drawing, can more clearly express the advantage and the operating principle of the utility model cylinder lock autoalarm by following.

Description of drawings

Fig. 1 is the structural representation of the utility model cylinder lock autoalarm;

Fig. 2 is the schematic diagram of the utility model cylinder lock autoalarm under the situation of normally unblanking;

To be the utility model cylinder lock autoalarm hit schematic diagram under spoon method situation at half-space to Fig. 3;

Fig. 4 is the schematic diagram of the utility model cylinder lock autoalarm under aciculiform unlocking method situation;

Fig. 5 is the functional module connection diagram of the utility model cylinder lock autoalarm;

Among the figure: 1 is interior pellet shot from a slingshot, and 2 is lock core, and 3 is outer pellet shot from a slingshot, and 4 is lock housing, and 5 is spring, and 6 is insulation sleeve, and 7 is little pellet shot from a slingshot, and 8 is alarm, and 9 is camera, and 10 is power supply, and two leads are connected with submissile with lock housing respectively.

The specific embodiment

At first same lead of little pellet shot from a slingshot linked to each other, add insulation sleeve after, equally be fitted into lock core with pellet shot from a slingshot in other, again another root lead is linked to each other with lock housing, each parts assembling finishing back congenerous circuit links to each other at last.

When using original key to unblank (as Fig. 2), circuit is connected, but be to use when illegally unblanking, as half-space spring lock method (as Fig. 3), during aciculiform lockaid gun unlocking method (as Fig. 4), outer pellet shot from a slingshot is moved up, of short duration or contact with lock housing for a long time, the whole functional circuit is connected, and the audible alarm module in the circuits for triggering is sent alarm sound and reminded owner and neighbours, the camera module record is lawless person's outward appearance down, helps police's evidence obtaining to arrest.Various functional modules can be expanded as required, to reach better anti-theft alarm result.

As mentioned above, the utility model cylinder lock autoalarm relies on existing cylinder lock technology, is improved on its basis, and simple in structure, the production and processing cost is low.Picking lock method to the overwhelming majority all has the warning effect, in conjunction with multiple anti-theft alarm function module, can realize warning function, can also help to arrest the lawless person.

An example of the utility model cylinder lock autoalarm is illustrated, and the various changes and modifications by this area other staff make can not break away from scope of the present utility model.

Claims

1. the cylinder lock autoalarm of a utility model, comprise: but interior pellet shot from a slingshot, outer pellet shot from a slingshot, little pellet shot from a slingshot, lock core, lock housing, spring, insulation sleeve and expanding function module, it is characterized in that: little pellet shot from a slingshot separates by the insulation sleeve parcel and with lock housing, spring is positioned at lock housing, interior pellet shot from a slingshot is in lock core inside, functional module is self-powered, is connected with submissile with lock housing respectively by two leads, and this moment, little pellet shot from a slingshot constituted a touch switch on the circuit with lock housing.

2. cylinder lock autoalarm according to claim 1 is characterized in that: the lock core outside has sulculus and is used for laying lead, avoids influencing the normal rotation of lock core simultaneously.

3. cylinder lock autoalarm according to claim 1 is characterized in that: the marginal distance of lock core lock housing is arrived greater than the maximum height difference between the anterior crown of key in the top of little pellet shot from a slingshot.
