Description
The utility model belongs to the lockmaking technical field, is a kind of tapered end that can burglar alarm.
The anti-theft alarm lock that uses only is provided with structures such as travel switch on lock box now, makes the violence person's of forcing open the door behavior, in time informs people by the theft-prevention structure on the lock box.But, this alarming lock, can not to by tapered end the keyhole behavior of illegally opening lock report to the police, therefore, theftproof performance is lower.
The purpose of this utility model is, a kind of Theft-proof and alarming lock is provided, and it can only be applicable to the key of oneself, opens as long as any other key or article enter keyhole, can cause warning, and is highly sensitive, safe and reliable.
The technical solution of the utility model is: Theft-proof and alarming lock has installation pellet shot from a slingshot 4 in lock housing 1, lock core 7, lock body 6, the lock core 7, piezoelectric element 5 is installed between lock housing 1 and lock body 6, and piezoelectric element 5 can be a piezo-resistance, and piezoelectric element 5 also can be a flexure strip.Connect wires 10 on piezoelectric element 5, electric wire 10 links with warning circuit, and warning circuit can be known any warning circuit.
The utility model can know that through test highly sensitive, safe and reliable, the utility model also has the structure that does not change existing lock in time to wanting that the behavior of illegally opening lock by keyhole causes warning, and manufacturing is simple, cheap advantage.
Description of drawings:
Accompanying drawing 1 is an external form schematic diagram of the present utility model, and accompanying drawing 2 is the A-A cross-sectional view in the accompanying drawing 1.Accompanying drawing 3 is vertical views of accompanying drawing 1.
The contrast accompanying drawing is described further embodiment of the present utility model:
1 is lock housing among the figure, the 7th, and lock core, the 6th, lock body is installed pellet shot from a slingshot 4 in the lock core 7, piezoelectric element 5 is installed between lock housing 1 and lock body 6.Piezoelectric element 5 can be a piezo-resistance, and piezoelectric element 5 also can be a flexure strip.Structure shown in the accompanying drawing of the present utility model is a kind of tapered end with cross core.Have groove 11 on its lock body 6, the top mounting screw 2 of groove 11, piezoelectric element 5 is installed in the groove 11.Can not slot on the lock body of other type tapered end.The afterbody of lock core 7 is installed and is dialled handle 3.After the utility model use to be installed, till screw 2 was screwed onto piezoelectric element 5 downwards and is in contact with it, when using this tapered end key operated, key entered keyhole and presses pellet shot from a slingshot 4, drove lock core 7 and dialled handle 3 and rotate, and realized opening.When destroying tapered end, lock body 6, lock core 7 rotate simultaneously, make screw 2 and lock body 6, and piezoelectric element 5 is produced pressure, its resistance is changed, and then cause and report to the police.9 is positioning beads among the figure, and its effect is to insert at non-tapered end key or article to reset when turning lock core 7, lock body 6.8 is packing rings among the figure.
