Abstract

The utility model relates to a special alarm and theft-proof lock for electronic warning systems. Circuit switches connected with a circuit of the electronic warning system are arranged at the carry position of a lock bolt in a lock bolt seat. The circuit switches are in the opposite state at the time of door locking or door unlocking of the lock bolt. The theft-proof lock of the utility model can be used for better reservation of the advantages and use functions of the prior art, and can have the function that the electronic warning system can be simultaneously closed at the time of unlocking, and the electronic warning system can be simultaneously opened at the time of door locking. Thus the utility model can effectively overcome the defects of the prior art, and can be an ideal replenishment to the existing electronic theft-proof warning system.

Description

The special-purpose alarm anti-theft lock of a kind of electronic warning system

The utility model relates to a kind of building anti-theft device, specifically refers to the special-purpose alarm anti-theft lock of a kind of electronic warning system.

Existing building anti-theft device generally can be divided into two kinds of mechanical type security door and electronic warning and anti-theft systems, the former mainly is made up of metal anti-theft door and corresponding mechanical antitheft lock, this anti-theft device mainly is to rely on its comparatively firm metal construction to realize its purpose of theftproof performance preferably, but any mechanical antitheft lock all has its corresponding crack method, thereby its theftproof performance all need be beaten certain discount; The latter then is by its comparatively perfect electronic warning system, to realize its center control or remote perception, reach antitheft purpose, though this method has more advantage, but the user must often remember to open or close this electronic warning system, otherwise will cause false alarm or fail to report the police, and this system be performed practically no function, and do not reach anti-theft effect.

The purpose of this utility model just is to provide a kind of electronic warning system special-purpose alarm anti-theft lock, the unique texture of contactor to be installed in mechanical antitheft lock or in the dead bolt seat by it, make it in function of use that keeps prior art preferably and advantage, also have and when unblanking, to close warning system, and when locking a door, open the function of warning system, thereby the deficiencies in the prior art have been overcome effectively.

The purpose of this utility model realizes in the following manner: the special-purpose alarm anti-theft lock of a kind of electronic warning system, mainly form by lock body, lock core, dead bolt and dead bolt seat, it is characterized in that in the dead bolt seat, being positioned at dead bolt carry place and be provided with the contactor that is connected with the electronic warning system circuit, this switch is locked a door or is in inverse state during non-locking a door at dead bolt, the foregoing circuit switch also can be arranged in the lock body, and is changed the state of contactor by the movement position of dead bolt in the dead bolt seat.

Adopt the special-purpose alarm anti-theft lock of electronic warning system of the present utility model, since adopted in mechanical antitheft lock or the dead bolt seat in the unique texture of contactor is installed, make it in function of use that keeps prior art preferably and advantage, also have and when unblanking, to close warning system, and when locking a door, open the function of warning system, thereby overcome the deficiencies in the prior art effectively, be the ideal complement of existing electronic anti-theft warning system.

Description of drawings:

Fig. 1 is that contactor is arranged on the outer example structure schematic diagram of lock body;

Fig. 2 is that contactor is arranged on the example structure schematic diagram in the lock body.

Wherein: 1-lock body, 2-lock core, 3-dead bolt, 4-contactor, 5-dead bolt seat, 6-switch connection.

Below in conjunction with drawings and Examples the utility model is further described.

As shown in Figure 1, the special-purpose alarm anti-theft lock of electronic warning system of the present utility model, mainly form by lock body (1), lock core (2), dead bolt (3) and dead bolt seat (5), it is characterized in that in dead bolt seat (5), being positioned at dead bolt (3) carry place and be provided with the contactor (4) that is connected with the electronic warning system circuit, its switch connection (6) directly is connected with the electronic warning system circuit, this contactor (dead bolt enters dead bolt seat bosom) when dead bolt pins is in on-state, is in off-state when dead bolt leaves the dead bolt seat.In the specific implementation, above-mentioned dead bolt seat also can save, and is directly replaced by metal door frame.Foregoing circuit switch (4) also can be set directly in the lock body (1), and is changed the state of contactor (4) by the movement position of the interior dead bolt of dead bolt seat (5) (3).

In use, when the user normally opened door lock, dead bolt left locking bolt (or metal door frame), drove contactor, and electronic anti-theft warning system circuit is disconnected, and warning system quits work, and has prevented the wrong report phenomenon; When the user leaves, make dead bolt enter the dead bolt seat by key, drive contactor, electronic anti-theft warning system circuit is connected, warning system is started working, and has prevented to fail to report phenomenon, thereby has realized the purpose of this utility model effectively.Adopt the embodiment of accompanying drawing 2, can achieve the above object effectively equally.

Claims

1, the special-purpose alarm anti-theft lock of a kind of electronic warning system, mainly form by lock body (1), lock core (2), dead bolt (3) and dead bolt seat (5), it is characterized in that being positioned at dead bolt (3) carry place and be provided with and electronic warning system circuit connecting circuit switch (4) in dead bolt seat (5), this contactor (4) is locked a door or is in inverse state during non-locking a door at dead bolt (3).

2, according to the special-purpose alarm anti-theft lock of the described a kind of electronic warning system of claim 1, it is characterized in that foregoing circuit switch (4) also can be set directly in the lock body (1), and change the state of contactor (4) by the movement position of the interior dead bolt of dead bolt seat (5) (3).

3, according to the special-purpose alarm anti-theft lock of the described a kind of electronic warning system of claim 1, it is characterized in that above-mentioned dead bolt seat (5) also can directly be replaced by metal door frame.
