Abstract
The invention provides a strong current damage protective device for an electric lock. The protective device adopts a mechanical lock head in which a mechanical key is used to rotate a rotor of a lock core to acquire the unlocking authorization. The protective device is characterized in that the rotor of the lock core is a touching piece; the lock head is fixedly provided with a micro switch(K) using a touch spring as a switch contact on a corresponding position; different rotating positions of the rotor of the lock core correspond to the closing or opening of the switch contact of the micro switch; and input ends and output ends of the micro switch and the switch contact are in serial connection with power lines or signal lines of an electric key contact and a control circuit of the lock. When strong current intrude, the protective device of the invention can effectively protect electric control devices in the electric lock from being damaged by strong current and improve the damage resistant property of the lock.
Description
Technical field
The present invention relates to a kind of electronic lock control circuit protective device.
Background technology
Various electronic locks all have control circuit, the active electronic lock is because there is power supply lockset inside, when key and lockset be noncontact unblank mode the time, this class lock is not vulnerable to strong electricity destroying, and when using the mode of unblanking of key and electronic lock contact, no matter whether electronic lock is active, this lockset all may be subjected to artificial strong electricity destroying.
For needing key to contact the lock system that just can unblank with electronic lock, two to four electrical contacts are generally arranged, be used to provide power supply or information source path.When the several electrical contacts of forceful electric power and this contact, do not have the lock control devices of forceful electric power protection destroyed, and cause and to unblank, and may open by mistake lock sometimes with regard to possibility.
200420021164.4 of application numbers are called " a kind of electronic lock circuit device " application for a patent for invention and disclose a kind of electronic lock circuit device that prevents that forceful electric power from unblanking, and its protective device is being subjected to protecting electronic lock not opened by mistake when artificial forceful electric power is imported.Above technical deficiency part is, but can make fastp-acting fuse fusing or cause electronic lock controlled circuit to damage when forceful electric power acquires a certain degree, thus the actual destruction of causing lockset.Thereby said apparatus can only protect forceful electric power not unblank, and can not protect electronic lock to be subjected to the destruction of forceful electric power.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point; provide a kind of strong electricity destroying-proof protecting device of electronic lock, so that can under the invasion of forceful electric power, electronic lock neither can take place open by mistake; can guarantee that also the lock control circuit does not wreck, to protect the safety of whole lockset.
Technical solution problem of the present invention adopts following technical scheme:
Strong electricity destroying-proof protecting device of electronic lock of the present invention adopts by the mechanical type tapered end of mechanical key rotational lock core rotor to obtain to unblank to authorize.
Design feature of the present invention is to be touch part with described lock core rotor, in the tapered end of correspondence position, fixedly install touching the microswitch K of reed as switch contact, the different turned position of lock core rotor is closed or open corresponding to the switch contact of microswitch; Described microswitch K is arranged in the power line or holding wire of electron key contact and lockset control circuit with the input COM and the output NO series connection of its switch contact.
Design feature of the present invention also be described lock core rotor be at cylindrical rotor periphery, vertically fan-shaped otch is set, the different pairing state in turned position of described lock core rotor is respectively: offset the switch contact closure of microswitch with lock core rotor periphery arc surface and shake-up reed; Or the fan-shaped otch of lock core rotor periphery offsets the switch contact unlatching of microswitch with touching reed.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, electronic lock can neither can take place and open by mistake under the invasion of forceful electric power in the present invention, can guarantee that also the lock control circuit does not wreck, to protect the safety of whole lockset.
2, the present invention utilizes microswitch to reach the inside and outside electric connection of physical isolation, and insulaion resistance is big, withstand voltage height, and electron key directly is not connected with the lockset control circuit, and volume is small and exquisite.
3, the present invention has very conventional prior art as mechanism's tapered end of authorization device, and its cost is low, and lock core is changed simple.
Description of drawings
Fig. 1 is a mechanical lock head structural representation of the present invention.
Fig. 2 is microswitch and lock core rotor fit structure schematic diagram in the mechanical lock head of the present invention.
Fig. 3 is a holding circuit schematic diagram of the present invention.
Below by the specific embodiment, the invention will be further described in conjunction with the accompanying drawings.
Number in the figure: 1 lock core rotor, 2 mechanical type tapered ends, 3 microswitches, 4 fan-shaped otch, 5 set bolts, 6 touch reed, 7 mechanical keys.
The specific embodiment
Referring to Fig. 1, adopt by the mechanical type tapered end 2 of mechanical key 7 rotational lock core rotors 1 to obtain to unblank to authorize; With lock core rotor 1 is touch part, in the tapered end of correspondence position, fixedly installs touching the microswitch 3 of reed 6 as switch contact, and the different turned position of lock core rotor 1 is closed or open corresponding to the switch contact of microswitch 3;
Referring to Fig. 2, in concrete the enforcement, can improve at the mechanical lock head of routine, wherein, lock core rotor 1 be at cylindrical rotor periphery, vertically fan-shaped otch 4 is set, the lock core rotor 1 different pairing state in turned position is respectively: offset with touching reed 6 with lock core rotor 1 periphery arc surface, it is closed that the switch contact of microswitch 3 is; Or the fan-shaped otch of lock core rotor 1 periphery 4 offsets with touching reed 6, and the switch contact of microswitch 3 is unlatching.The range of touching reed 6 by lock core rotor 1 half through decision, when mechanical key 7 resets when taking out, lock core rotor 1 resets, and touches reed 6 and also restores to the original state, relevant circuit connection is cut off in microswitch K action.
Referring to Fig. 3, microswitch K is arranged in the power line or holding wire of electron key contact and lockset control circuit with the input COM and the output NO series connection of its switch contact.
Circuit shown in Figure 3 has provided the forceful electric power protected mode of three core contact-type electronics locks; electrical protection circuit is made up of one to three microswitch; microswitch K is connected with the electron key contact with its switch contact input COM, and the output NO of microswitch K links to each other with the power supply or the signal of lock control circuit.Authorize with mechanical key, under unwarranted situation, have only electric a connection between electron key contact and the lockset control circuit, do not constitute electric loop, thereby protected the lockset control circuit.When after authorizing, the shake-up reed of microswitch K is depressed, and a pair of input COM forms conducting with separately output NO respectively and is connected, thereby realization provides the loop of power supply and communication to the lockset control circuit.
