Abstract
The invention discloses a safety lock which can be prevented from being unlocked by force and comprises a lock shell, a key hole, a spring, a bolt and a locking device corresponding to the bolt. The invention is characterized in that a normally closed switch capable of forced induction, button cells and an alarm buzzer connected through a circuit are arranged inside the lock shell. The lock is additionally provided with the mini-type normally closed switch, button cells and the alarm buzzer based on the prior lock; and the mini-type normally closed switch, the button cells and the alarm buzzer are connected into a circuit through wires. In this way, due to the pressure produced by riveting the lock shell, the normally closed switch is in the off-state, and an alarm circuit does not work. However, once the lock is unlocked by force, the normally closed switch is closed due to loss of pressure so that the alarm circuit makes sound for alarming, so that a thief is frightened, and the safety of the bicycle is improved. In addition, the safety lock is simple in structure, low in cost and applicable for promotion.
Description
Technical field:
The present invention relates to a kind of lockset that is applied to bicycle, particularly a kind of safety pick-proof vehicle lock.
Background technology:
At present, all there are the characteristics of anti-theft capability deficiency in the bicycle lock that is generally adopted, and there is fault of construction in its reason when being lock design itself.By dissecting existing lock, we find this key position of dead bolt of lock, in case pried open by the thief, spring will retract dead bolt and lock is opened.So just do not have the stolen effect of bicycle that prevents.So at this problem, we have developed a kind of novel Bicycle Anti-Picklock with warning function.
Summary of the invention:
The purpose of this invention is to provide a kind of safety pick-proof vehicle lock.
According to above-mentioned purpose, its technical scheme is as follows:
A kind of safety pick-proof vehicle lock comprises lock housing, key socket, spring, dead bolt and the card locking device corresponding with dead bolt; It is characterized in that, also be provided with the normally closed switch that possesses pressure sensitive in lock housing inside, and the button cell and the alarm buzzer that connect by circuit.
Beneficial effect of the present invention is:
This bicycle anti-prying alarm lock is installed miniature normally closed switch, button cell and an alarm buzzer on existing lock basis, and carries out the circuit connection by lead.Make at ordinary times because the pressure that lock shell riveted is produced is in off state by normally closed switch, and this is that warning circuit can not worked, but in case pry open lock, normally closed switch can be because losing pressure closure, make the warning circuit sounding alarm.So just can play the fright effect, thereby improve the safety of bicycle the thief.In addition this apparatus structure simple, fake cheap and be fit to promote the use of.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
Further specify the present invention below in conjunction with accompanying drawing.
Referring to Fig. 1, a kind of safety pick-proof vehicle lock of the present invention comprises lock housing 1, key socket (not marking among the figure), spring 2, dead bolt 3 and pintle hook lock 4 devices corresponding with dead bolt; Also be provided with the normally closed switch 5 that possesses pressure sensitive in lock housing inside, and the button cell 6 and the alarm buzzer 7 that connect by circuit.
Above-mentioned lock is installed miniature normally closed switch, button cell and an alarm buzzer on existing lock basis, and carries out the circuit connection by lead.Make at ordinary times because the pressure that lock shell riveted is produced is in off state by normally closed switch, and this is that warning circuit can not worked, but in case pry open lock, normally closed switch can be because losing pressure closure, make the warning circuit sounding alarm.So just can play the fright effect, thereby improve the safety of bicycle the thief.In addition this apparatus structure simple, fake cheap and be fit to promote the use of.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
