Brief description
The structural representation of the theftproof lock that Fig. 1 is provided by the utility model embodiment.
Wherein:
1-lock body, 2-chain, 3-wire.
Detailed description of the invention
Core of the present utility model is to provide a kind of theftproof lock, and this theftproof lock can increase anti-theft feature, reduces wrong report, carries
High warning accuracy.
In order to make those skilled in the art be more fully understood that the utility model scheme, below in conjunction with the accompanying drawings and specifically
The utility model is described in further detail for embodiment.
Refer to Fig. 1, the structural representation of the theftproof lock that Fig. 1 is provided by the utility model embodiment.
The theftproof lock that the utility model provides, as shown in Figure of description 1, including lock body 1, lock body 1 is provided with leads
Line the 3rd, power supply, electromagnet, armature and alarm.Wire the 3rd, power supply and electromagnet form loop, herein referred to as close back
Road；And the loop that armature, power supply and alarm are formed, herein referred to as alarm circuit.
It should be evident that when the 3rd, power supply connects wire with electromagnet, closed-loop path connects；When armature, power supply and warning
During device connection, alarm circuit connects.And it is known that electromagnet and armature are for being equipped with；That is, armature can be at electromagnet
It is adsorbed in electromagnet side under effect, or when electromagnet loses magnetism, armature is away from electromagnet side.
When theftproof lock normally works, the closed-loop path being formed between wire the 3rd, power supply and electromagnet normally works, and
And electromagnet obtains electric under the effect of power supply, thus produce magnetic；Magnetic electromagnet is now carried to adsorb armature.Due to rank
Iron is adsorbed by electromagnet, thus the alarm circuit between armature power supply and alarm cannot be formed, therefore at theftproof lock just
When often working, alarm circuit is off.
When theftproof lock is destroyed, when wire 3 is damaged, the Guan Bi being formed between wire the 3rd, power supply and electromagnet is returned
Road cannot normally work, electromagnet dead electricity, thus loses magnetism；Thus electromagnet cannot adsorb armature, armature is returned in situ,
Thus by and the alarm of power supply between alarm circuit connect, and alarm is triggered by the alarm circuit after connecting, thus real
Existing warning function.So, due to the warning function of alarm, the lawless person unlocking violence plays effective fright and makees
With, thus improve the anti-theft feature of theftproof lock.
In order to optimize the structure of theftproof lock further, the lock body 1 of this paper includes chain 2 and tapered end, as specification is attached
Shown in Fig. 1.It should be evident that 2 sealing process of chain, thus realize the function of lock, and tapered end is used for inserting key, it is achieved lock
The unlatching of chain 2.
Wire 3 is set in chain 2, and power supply, electromagnet, armature and alarm are set in tapered end；Namely
Say, when theftproof lock meets with violence dismounting, often set about at the chain 2 of structure more weakness, and arrange in chain 2 herein
Wire 3, therefore once chain 2 meets with violence dismounting, will certainly destroy wire 3, and the damage of wire 3 can cause alarm circuit
Connection, thus realize above-mentioned technique effect.Of course, it is possible to according to actual needs, wire the 3rd, power supply, electromagnet, armature and report
Alert device can be arranged on other diverse locations, will not be described in great detail herein herein.
For above-mentioned alarm, in order to be different from other warning devices, preferably alarm is set to sound and light alarm herein
Device；I.e., it is possible to audible-visual annunciator is set to the contents such as voice broadcast, contributes to user and identify.
On above-mentioned basis, switch can also be set, connect with power supply；In addition to this it is possible to utilize enclosing cover to hide
Power supply and switch, and utilize cover lock to pin enclosing cover in lock body 1.That is, for the ease of changing power supply and preventing in Guan Bi
On loop, electric current deficiency causes wrong report to cause the enclosing cover of trouble, power supply and switch to use together with external cover lock lock, power supply simultaneously
Being arranged around the switch of this circuit, once wrong report can be closed in time.
Lock body 1 is internal is additionally provided with gsm module, and gsm module is connected with alarm circuit；When alarm circuit connection
When, gsm module connects user.It is to say, sensor can be used to detect the state of car in real time, once electric motor car goes out safely
Now abnormal, will pass through gsm module and real-time for car state is passed to car owner.The possibility of wrong report can be reduced, reduce the product of noise
Raw, prevent from disturbing residents, improve the accuracy reported to the police.Certainly, theftproof lock of the present utility model is not restricted to be used in electric motor car,
Can be also used on the object that other needs are locked.
It in order to definitely know the position of theftproof lock, in lock body 1, is additionally provided with positioner, to facilitate user to know
Its accurate location.
The utility model uses surface structure and the stock of U-shape lock, has keyhole and power supply lid, outward outside tapered end
Lid uses cover lock to close.Vacate segment width in chain and place wire, use the mode of wire occlusion even at U-shape lock joint
Connect.In tapered end, main power source connects with armature and the electromagnet of conductor material playing on-off action, simultaneously with in switch and chain
Wire connects.Alarm circuit connects alarm and switch, and this loop is entirely in tapered end.When electric motor car normally uses or parks safely
When, closed-loop path, main power source place closes all the time, and electromagnet absorption armature makes alarm circuit disconnect, and alarm does not acts on；Work as electricity
The just stolen i.e. theftproof lock of motor-car is disconnected by main power circuit during pinch off, alarm circuit circuit ON, and alarm work sends
The information alert stolen, it is simple to car owner or police find situation in time, recover mistake car in time.
The utility model simple in construction, it is easy to accomplish.Inherently play increase anti-theft function function, reduce wrong report and
The generation of noise, improves warning accuracy.
Above theftproof lock provided by the utility model is described in detail.Specific case used herein is to this
The principle of utility model and embodiment are set forth, and the explanation of above example is only intended to help and understands the utility model
Method and core concept.It should be pointed out that, for those skilled in the art, without departing from this practicality newly
On the premise of type principle, can also carry out some improvement and modification to the utility model, these improve and modification also falls into this reality
With in novel scope of the claims.
