Abstract

The utility model can alarm and automatically lock the bolt when the unnecessary movement of the bolt is generated. An alarm self-bolting circuit is arranged on the basis of a spring door lock; an alarm terminal which can carry out processing circuit and provide the alarming when the bolt moves is arranged; a self-bolting mechanism is arranged for locking the bolt when alarming; a transfer switch which can control the operating state of the alarm self-bolting circuit is arranged; the transfer switch is in the early warning status through the processing circuit when an owner leaves; the transfer switch can be transferred to the switching-off state for assuring the normal use of the owner before the owner unlocks.

Description

Alarm self-bolting anti-theft door lock

The utility model belongs to lockset, mainly proposes a kind of warning that can provide warning and automatically dead bolt is locked when dead bolt moves from fastening safe-guard door lock with a bolt or latch.

In order to make dwelling house and office's door lock can play protective action effectively, its structure many improvement have been carried out, on the basis of common spring door lock, insurance institution has been proposed, and the position that may go wrong set up alarm against theft, played the antitheft effect of Denging preferably, its warning and theft-prevention structure are more, and the mode of realization is also varied.

The utility model proposes a kind of warning from fastening safe-guard door lock with a bolt or latch, can unnecessary providing when mobile be taken place at dead bolt and report to the police and, and have characteristics simple in structure, unique automatically with the dead bolt locking.

Technical solutions of the utility model are: on the basis of pin tumbler lock, warning is set, fastens circuit with a bolt or latch certainly, alarm terminals is set, provide warning in order to connect circuit when dead bolt moves; Dead bolt is set from bolt mechanism, in order to when reporting to the police, dead bolt is locked, and be provided for controlling warning, fasten the changeover switch of circuit working state with a bolt or latch certainly, make circuit be in alert status in order to when owner leaves, switch is gone to the connection circuit, before owner unblanks, circuit is disconnected its conversion, thereby this circuit is not worked when owner unblanks.

Alarm terminals mainly is made up of front end contact and terminal screw, is arranged on the lock body contact contact dead bolt; Dead bolt mainly is made up of dc coil, iron core and metal bolt from bolt mechanism, is arranged on the lock body, and latch is positioned at the pin hole top on the dead bolt.

Changeover switch has interconnective a plurality of work gear and 0 gear of an inoperative is arranged, its bull stick is connected with circuit power, alarm terminals is connected with circuit by changeover switch, the warning microphone device is set in the circuit, be connected in the circuit from bolt mechanism and lock body, and another extremely direct and power cathode connection.

The utility model structure design is comparatively unique simple, when leaving, owner uses key turn changeover switch, its bull stick rotates with the work gear and contacts, the contact of alarm terminals is promptly connected (contact is connected with the work gear) with circuit, circuit promptly is in early warning status, when the key of human preparation or master key or other mode turn door locks move dead bolt, the metalwork of dead bolt touches mutually with the alarm terminals contact, whole warning circuit structure is logical to provide warning, dead bolt is logical from bolt mechanism circuit structure simultaneously, slotting Xiao of this mechanism promptly inserts the slotting Xiao Kongzhong of dead bolt downwards, and the dead bolt locking is no longer mobile.

The utility model embodiment provides following accompanying drawing:

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is an alarm terminals structural representation in the utility model.

Accompanying drawing 3 be in the utility model dead bolt from the bolt mechanism schematic diagram.

In conjunction with the accompanying drawings the utility model structure is specifically described:

As shown in drawings: the utility model adopts pin tumbler lock as basic lock body 1, it adds nonmetals such as bakelite piece 3 at dead bolt 5 rear end faces, have slotting Xiao hole 17 at dead bolt bakelite piece and metalwork, warning is set, dead bolt is from fastening circuit with a bolt or latch, thereby alarm terminals 4 determines whether the alert circuit of structure circular in order to contact with dead bolt, it is by terminal screw 11, spring 13 and constitute as the steel ball 14 of contact, be encapsulated in nonmetals such as the bakelite cylindrical shell (daughter of bakelite post ends) 12, be arranged on the lock body upper side, as the steel ball roof pressure of contact on the dead bolt rear end face, its roof pressure is on the metal covering of dead bolt when dead bolt moves forward, thereby makes alarm terminals that is connected with circuit and the lock body that links to each other with the circuit alert circuit of structure circular that links to each other; One door lock is set from bolt mechanism 2, it mainly is made of dc coil 8, iron core 7, latch 9 and plug housing 6, be encapsulated in the housing 10 of nonmetals such as bakelite, be installed in the lock body front, pin hole 17 central lines on latch 9 and the dead bolt 2, be connected in the circuit from bolt mechanism and lock body, and another extremely direct and power cathode connection.Link up dead bolt simultaneously from fastening circuit with a bolt or latch when warning circuit is linked up, metal bolt 9 promptly moves down to be inserted in the dead bolt end face pin hole 17, and dead bolt is locked.

Be provided with one in order to the control warning, changeover switch 15 from the door bolt circuit working state, it has a plurality of continuous work gears and inoperative 0 gear, alarm terminals 4 is connected with circuit by changeover switch, specifically alarm terminals is connected with the work gear of changeover switch, thus, when the bull stick of changeover switch forwards the work gear to, alarm terminals promptly was connected with circuit and was in alert status this moment, it is that the ditch circuit passband provides and reports to the police and dead bolt is locked that dead bolt moves, when the bull stick of changeover switch forwards 0 gear to, this moment, alarm terminals promptly disconnected with circuit, reported to the police and other actions even dead bolt moves also not provide.

Changeover switch is arranged on the optional position in the body, its rotating shaft is inserted in the perforate of door body, drive bull stick work by the key turn rotating shaft of joining with its shaft hole kiss, changeover switch adopts the changeover switch commonly used generally sold on the market (ten grades, five grades all can) only its a plurality of gears as the work gear to be interconnected and gets final product.

Report to the police to reach from fastening circuit with a bolt or latch and adopt dc source, voltage can be 3V, 6V, 12V etc.

Its alarm 16 adopts piezoelectric ceramic piece or sounding electronic integration block etc.

Claims
