Abstract
The utility model relates to an electric device used for locking and unlocking buildings, containers and other objects, in particular to an electric unlocking device, wherein, a relay 2, a transformer 3, a control switch 4 and a lock bolt 5 are arranged on a lock body 1; the lock bolt 5 is connected with the relay 2; the output of the transformer 3 is connected with the control switch 4; the control switch 4 is connected in series with the relay 2; the input of the transformer 3 is connected in parallel with the relay 2. The utility model is characterized in that 220 V civil electricity is used as the power source to control the high-power relay while avoiding the disadvantages of loud noise and high electric consumption from using high-power motor in the prior art; furthermore, the transformer outputs low-voltage weak current to control the operation of the relay and further control the locking and unlocking movements of the lock bolt. The utility model has the advantages of simple structure, strong practicability, convenient assembly, safe application, less electric consumption, low noise, easy realization of precise control and easy popularization.
Description
One, technical field
The utility model belongs to a kind of and is used to build or object such as container opens and closes the electrical propulsion unit of locking, especially electronic unlocking apparatus.
Two, background technology
At present in the known technology, except that general pure machine work mechanism lockset, technology with memory function magnetic force control unlocking action, new technologies such as electronic induction unlocking technique are used and are being occurred, as Chinese patent 00814454.0 electromechanical lock, having one has the rotation insert of dead bolt to insert lock housing, with the axle in the hole that is inserted into the rotation insert, axle comprises the electromagnet with fixator, the port of this fixator and the groove of rotation insert matches in the mode of the voltage that transmits electromagnet simultaneously, when axle rotates, fixator leans against the port of the groove that rotates insert and rotates from the axle transmission, when electromagnet did not have voltage and axle rotation, fixator was released groove under the effect of deadweight, and the rotation of axle is not transferred to the rotation insert.And for example Chinese patent 02205844.3 improved electric lock is made of housing and the lid that is arranged on electromagnetic coil, locking bolt, driving lever, block body and casing opening in the housing; Be provided with the magnetic induction rod that runs through in the electromagnetic coil, the magnetic induction rod is provided with the recovery spring; Locking bolt is by framework and be hubbed in the framework and have the key that recovers spring and forms, and the side of framework is pivoted with and has the swing arm that recovers spring, and the outside of swing arm convexes with a resistance piece, the adjacent edge of key and swing arm is corresponding convex with mutual against pushing block and jacking block; Driving lever is provided with pull sheet and form lug boss in the middle section of two tops corresponding to the two ends of magnetic induction rod; Block body is hubbed at the side of swing arm and is provided with the recovery spring, is provided with a runner corresponding to the resistance piece of swing arm, and the lug boss of corresponding driving lever is formed with the pushing part.The driving lever that is controlled by electromagnetic coil can be stirred block body and resist or break away from the locking bolt swing arm, reaches to unblank or the state of locking.Especially for large-scale storehouse door etc., prior art is general directly does power source with the civilian electricity of 220V, by opening and closing the Motor Control lockset, exist in the application dangerous, power consumption is many, noise is big, can't realize shortcoming such as accurate control.
Do not see as yet in the known technology that the civilian electricity of direct application 220V does power source, and open and close the electric lock device of lockset by the control of low-voltage light current.
Three, technology contents
The purpose of this utility model is to propose the civilian electricity of a kind of direct application 220V and does power source, and controls the electric lock device that opens and closes lockset, promptly electronic unlocking apparatus by low-voltage light current.
The measure that realizes the present utility model purpose is: fixed relay, transformer, gauge tap and dead bolt on the lock body, dead bolt is connected with relay, the transformer output is connected with gauge tap, and gauge tap is connected with relay, and the transformer input is in parallel with relay.
Advantage of the present utility model is: directly use the civilian electricity of 220V and do power source, and by the work of transformer output LOW voltage light current control relay, and further control the dead bolt switching motion, simple in structure, practical, be convenient to install, can realize safety, little power consumption, little, the also easily accurately control of realization of noise in the application, and be beneficial to popularization.
Four, description of drawings
Fig. 1 is the electronic unlocking apparatus structural representation of the utility model embodiment 1
Fig. 2 is the circuit part operating principle schematic diagram of the utility model embodiment 1
Five, the specific embodiment
Embodiment 1: fixed relay 2, transformer 3, gauge tap 4 and dead bolt 5 on the lock body 1, and dead bolt 5 is connected with relay 2, and transformer 3 outputs are connected with gauge tap 4, and gauge tap 4 is connected with relay 2, and transformer 3 inputs are in parallel with relay 2.
The civilian electricity of 220V is after transformer 3 step-downs are 12V light current, through bridge rectifier pipe D
1-D
2Rectification is again through 1000 μ F filter capacitor C
1Filtering is by gauge tap 4 (K
1), control relay 2 (K
2) action, as gauge tap 4 (K
1) when connecting, relay 2 (K
2) carry out the adhesive action, dead bolt 5 withdraws from from draw-in groove 6; As gauge tap 4 (K
1) when disconnecting, relay 2 (K
2) carry out separating action, dead bolt 5 snaps in the draw-in groove 6.
Directly use the civilian electricity of 220V and do power source, can control the bigger relay of power, but drawbacks such as strong noise, high power consumption when but having avoided using the bigger motor of power to work, and by the work of transformer output LOW voltage light current control relay, and further control the dead bolt switching motion, simple in structure, practical, be convenient to install, can realize safety, little power consumption, little, the also easily accurately control of realization of noise in the application, and be beneficial to popularization.
