The utility model has the advantage of: simple in structure, easy and simple to handle, higher with respect to its lock body degree of protection of traditional mechanical lock, applicable lock body is exposed to completely for a long time in outdoor or worse environment and uses, and the conditional electronic lock with respect to built-in power, charged not in this passive electronic lock lock, so the volume of lockset is little, cost is low, and has extremely long maintenance period.
Accompanying drawing explanation
Fig. 1 the utility model structural representation.
The specific embodiment
Now by reference to the accompanying drawings, the utility model specific embodiment is described in detail in detail:
As shown in Figure 1, a kind of passive electronic lock, comprises upper lock body 2, down lock body 9, lock dog 7, and down lock body 9 is connected on upper lock body 2, and down lock body 9 and upper lock body 2 the two can relatively rotate; Mode by quadric injection mould on one end of upper lock body 2 is connected with electric joint Terminal 1, and electric joint Terminal 1 is tightened to one with upper lock body 2, and keeps electrical insulation with upper lock body 2; In upper lock body 2, be provided with cavity, be provided with successively from the inside to the outside control circuit board 3, electromagnetic coil 5, jam plate 6 in cavity, jam plate 6 is connected in the bottom of upper lock body 2; Control circuit board 3 keeps electric connection by three screws with three electric joint Terminals 1, and is fixed in the cavity of upper lock body 2; Electromagnetic coil 5 is arranged in the cavity of upper lock body 2 and by electric wire and 3 electric connections of maintenance of control circuit board; Jam plate 6 is provided with square opening 62; One end of lock dog 7 is connected with output shaft 8, and the other end is connected in the center hole 51 of electromagnetic coil 5 by lock dog back-moving spring 4 and through square opening 62; Output shaft 8 is connected with outside link gear.
The cylindrical of the utility model upper lock body 2 is provided with annular groove 21, and down lock body 9 is connected on annular groove 21 by pinning 10, and the two links together to make upper lock body 2 and down lock body 9, and the two can relatively rotate but can not be separated.
The bottom of the utility model upper lock body 2 is provided with groove 22; The edge of institute's jam plate 6 stretches out and is formed with chimb 61; Chimb 61 is connected with groove 22.
As shown in Figure 1, the utility model lock dog 7 is comprised of round 71 and square body 72, and round 71 center is provided with blind hole; The blind hole of round 71 is stretched in lock dog back-moving spring 4 one end, and the other end is connected in the cavity of upper lock body 2; Round 71 is located in the center hole 51 of electromagnetic coil 5 through square opening 62; Square body 72 is connected in the square groove 81 of output shaft 8 through square opening 62.
The utility model square opening 62 is three holes more than limit, and square body 72 is three square bodies more than limit, and square groove 81 is three square grooves more than limit; The limit number of square opening 62, square groove 81 and square body 72 is identical.
Operating principle of the present utility model is: when outside Lock-Picking Devices produce electric connection with electric joint Terminal 1, outside Lock-Picking Devices give control circuit board 3 power supplies by electric joint Terminal 1, and send to control circuit board 3 code of unblanking, after receiving the code of unblanking, the inside microcomputer of control circuit board 3 compares, a kind of in following two kinds of results will be produced: the first: as correct in the code of unblanking, 3 current supply circuits of connecting electromagnetic coil 5 of control circuit board, electromagnetic coil 5 obtains electric generation magnetic force, the central post of upper lock body 2 and lock dog 7 are magnetized into a pair of opposite pole, because the central post of upper lock body 2 maintains static, so lock dog 7 overcomes the elastic force of lock dog back-moving spring 4 under the effect of magnetic force, central post motion to upper lock body 2, until with its laminating (now the bottom surface of the end face of the round 71 of lock dog 7 and the cavity of upper lock body 2 fits), the square body 72 of lock dog 7 stretches in the square opening 62 of jam plate 6 simultaneously, so far unlocking action completes.If at this moment rotate the jam plate 6 that upper lock body 2 is fixed thereon, will together rotate, because the square body 72 of lock dog 7 enters into the square opening 62 of jam plate 6, so lock dog 7 also together rotates with jam plate 6.The square body 72 of lock dog 7 stretches in the square groove 81 of output shaft 8 simultaneously, and when lock dog 7 rotates, output shaft 8 will play rotation with one.Output shaft 8 can connect all kinds of outside swing arms or lever, for driving various forms of locking bolts, dead bolt to complete unlocking action.As correct in the code of unblanking in brief, upper lock body 2, toward certain orientation, is turned an angle and just can pull open dead bolt or locking bolt is opened lock.
The second: as incorrect in the code of unblanking, 3 current supply circuits of disconnecting electromagnetic coil 5 of control circuit board, electromagnetic coil 5 does not produce magnetic force, the bottom of the square groove 81 of output shaft 8 shifted lock dog 7 onto by lock dog back-moving spring 4, at this moment the square body 72 of lock dog 7 leaves the square opening 62 of jam plate 6, if the jam plate 6 that at this moment rotation upper lock body 2 is fixed thereon will together rotate, because the square body 72 of lock dog 7 leaves the square opening 62 of jam plate 6, only has the round 71 of lock dog 7 in the square opening 62 of jam plate 6, so lock dog 7 just can not together rotate with jam plate 6, output shaft 8 can not together rotate with jam plate 6 like this, the swing arm being fixed thereon, connecting rod just cannot drive locking bolt, dead bolt completes unlocking action, as incorrect in the code of unblanking in brief, upper lock body 2 is 360 degree idle running, cannot driver output axle 8 rotates also just cannot pull open dead bolt or locking bolt is opened lock.
