The specific embodiment
Refer to Fig. 1 to Fig. 5, the electrical anti-error lock shown in figure, comprise shell, and this shell is comprised of protecgulum 101, body 102, lower cover 103, bonnet 104; This protecgulum 101, this lower cover 103, this bonnet 104 are respectively equipped with sealing ring 105 with the junction of this body 102, with the waterproof and dustproof performance that guarantees that this shell is good.Be provided with unlock hole 106 on this body 102, on this lower cover 103, be provided with latch arm hole 107; This unlock hole 106 when placing release, intelligent computer key used; The locking bar 108 of this latch arm hole 107 for placing following locking mechanism.
In the enclosure, this locking mechanism comprises locking bar 108, lock the securing rod 109 of this locking bar 108, be located at the securing rod return spring 110 of these securing rod 109 1 ends in above-mentioned locking mechanism setting; And, for controlling the unit that unblocks of this securing rod 109, this unit that unblocks comprises electric unblock unit and the machinery unit that unblocks.
The described electric unit that unblocks comprises the operator link 112 that unlock button 111, an end are connected with this unlock button 111, this operator link 112 and these securing rod 109 clampings; And, for the lock pin 113 that locks this operator link 112, this lock pin 113 is located in electromagnet 114 and controlled by this electromagnet 114, this electromagnet 114 is connected with signal of telecommunication control circuit.
Refer to Fig. 6, described control circuit comprises terminal board J1, travel switch, voltage transformation module U1.In the present embodiment, the travel switch of take arranges four and is explained as preferred version, but is not limited to this, and in actual use, the trip switch can arrange several.
Described terminal board J1 is 10 pin terminal boards, and its 1 pin and 2 pin are for receiving the voltage signal of unblanking of main control system output, its respectively with input Vin1 pin and the Vin2 pin of this voltage transformation module U1.Described travel switch K1, K2 export normally closed signal, and it is respectively by 3 pin, 4 pin, 5 pin, the 6 pin outputs of this terminal board J1.Signal is often opened in described travel switch K3, K4 output, and it is respectively by 7 pin, 8 pin, 9 pin, the 10 pin outputs of this terminal board J1.The output of described voltage transformation module U1+Vo pin is connected with the two ends of this electromagnet respectively with the GND pin.
The trip K switch 1, K2, K3, K4 are controlled by the locking bar 108 of this lockset.When locking bar 108 inserts latch arm hole 107, travel switch K1, K2 are normally closed, and travel switch K3, K4 often leave; After locking bar is opened disengaging latch arm hole 107, travel switch K1, K2 become disconnection, and travel switch K3, K4 connect.
Preferably, between the input Vin1 pin of described voltage transformation module U1, Vin2 pin, be provided with pressure cell R5, for example, for the protection of this control circuit (, preventing that this control circuit is struck by lightning).
Preferably, when carrying out signal of telecommunication release, show for convenience the lockset state, the described electric unit that unblocks also is provided with a release indicating device.Refer to Fig. 5 and Fig. 7, described release indicating device is for being provided with a circuit board 115.This circuit board 115 is provided with LED state lamp, resistance R 1 and for the capacitor C 1 of filtering; This LED state lamp and the two ends that are connected to electromagnet 114 after this resistance R 1 is connected, this capacitor C 1 is in parallel with this LED state lamp.
Preferably, body is provided with light-guiding pillar 116, for the light that the LED state lamp is sent, derives outside housing.
Preferably, operator, after capable of being unlocked by pressing button 111, is upspring automatically for making unlock button 111, in this unlock button 111, is provided with return spring 117.
Please continue to consult Fig. 1 to Fig. 5, the described machinery unit that unblocks comprises and being located in this shell, for the RFID module (not shown) of identification intelligent computer key and be located at the lock knob 118 in the unlock hole 106 of this body 102, an end of this lock knob 118 is connected with described securing rod 109.
Preferably, the state for ease of the monitoring lockset, also be provided with a locking bar state detection unit in this electrical anti-error lock.This locking bar state detection unit comprises push shaft 119 and the touch-switch 120 linked with this push shaft 119; This push shaft 119 is located in the latch arm hole 107 of this body 102, and when described locking bar 108 inserts this latch arm hole 107, this push shaft 119 contacts with this locking bar 108.
Preferably, for preventing this locking bar 108, with locking object 121, separate, the phenomenon of empty locking occurs, this locking bar 108 is connected in locking object 121, and for example, movable snaps fit onto on locking object 121.
During this electrical anti-error lock operation, there are signal of telecommunication release, mechanical release, three kinds of mode of operations of emergency mechanical release.
When signal of telecommunication mode of operation, main control system output one voltage signal of unblanking, after terminal board in the signal of telecommunication control circuit of the electric unit that unblocks receives the voltage signal of unblanking, be converted to low-voltage dc voltage and export electromagnet 114 to through the voltage transformation module U1 voltage signal of unblanking, electromagnet 114 produces magnetic force, by lock pin 113 sucking-off from the draw-in groove of operator link 112, make operator link 112 in movable state; Simultaneously, terminal board meeting driving LED circuit board 115, make the LED state lamp on LED circuit plate 115 light by pre-defined rule, and the light of generation conducts to outside shell by light-guiding pillar 116, the prompting operator; Now, operator is pressed unlock button 111 moves operator link 112, and operator link 112 moves the generation lateral thrust, forces the end of securing rod 109 to exit the draw-in groove on locking bar 108; Now, under the effect of external force, locking bar 108 just can exit latch arm hole 107, and after locking bar 108 exits, push shaft 119 loses and contacts with locking bar 108, produces displacement and decontrols touch-switch 120, and touch-switch 120 produces a switching signal and feeds back to main control system.During locking, operator directly is inserted into locking bar 108 in latch arm hole 107, and securing rod 109 is again locked by locking bar 108, and locking bar 108 links together with locking object 121, therefore the phenomenon of empty locking can not occur.In locking bar 108 insertion process, with push shaft 119, contact, push shaft 119 touches touch-switch 120, and touch-switch 120 produces a switching signal and feeds back to main control system.
During mechanical release, operator directly is inserted into Computerized intelligent key (not shown) in unlock hole 106; As operation order and the RFID module of Computerized intelligent key is complementary, the Computerized intelligent key will rotate, and drives lock knob 118 simultaneously and rotates, and lock knob 118 produces lateral thrust while rotating, and forces the end of securing rod 109 to exit the draw-in groove on locking bar 108; Now, under the effect of external force, locking bar 108 just can exit latch arm hole 107.
As occurred, emergency, operator can be used the mechanical type key directly to rotate lock knob 118, carries out the operation of emergency release, prevents that contingency from occurring.
The foregoing is only preferred embodiment of the present utility model, not be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and all by the scope of the utility model claims, is covered.
