Unlock the principles of magnetic lock of knowledge"

Each magnet two pole, an arctic (N) and a South Pole (S), magnet has the same, opposites attract. The working principle of magnetic lock exactly is to make use of this feature, the magnet by permanent magnets, magnetic beads made locks.

Magnetic locks, there are two pieces of rectangular plate is a piece of board, another piece of the plate. When hard pull the lock body and lock of the state of the lock beam, lock beam will squeeze on dynamic activity board convex block, make the active plate has a direction of the force to the fixed plate, if the board can move a distance in the direction of the fixed plate, can open the lock.

In these two pieces of rectangular plate on the plane of the longitudinal, respectively with four holes every board. One end of the four magnetic beads are respectively fixed with a magnetic beads fine some copper wire, copper wire on the four magnetic beads respectively in four hole on the fixed plate. Four hole on the fixed plate than magnetic beads fine than copper wire of the thick, so the magnetic beads can be a full range of shaking on the fixed plate, but after fixed inside the lock, because of limited by lock body can't longitudinal movement. Magnetic beads have no fixed wire end toward the outside lock key slot, magnetic beads fixed copper wire toward the activity at the end of the plate. Because the lock in the interaction of the four magnetic beads, magnetic bead wire and activities at the end of the board of four hole is not in a straight line. When there is a pull on the lock lock liang, lock beam will squeeze on dynamic activity board convex block, activity board at this time although the direction of the force to the fixed plate, but then because there is no hole on the activity board, copper wire is copper wire can resist activity board, can be in direction to the fixed plate limit board, so I can't make the lock open; When the appropriate key on the lock outside of the key slot, locked inside the magnetic beads will be locked outside the magnetic beads in the key of suction, make four copper wire in the lock, aided by magnetic beads is respectively aim with the hole on the activity board, when there is tension on two lock lock liang, activity board on the convex block to be squeezed, can overcome the force of the spring in the lock, the fixed plate direction, when four copper wire can enter the activity board hole, activity board can move a distance in the direction of the fixed plate, the lock can be opened. In order to make the copper wire can be smoothly into the activity board hole, copper wire is pointed shape at the other end.

When lock beams on the lock, lock beam is the pull force of the spring in the lock, lock beam into the lock hole, at the same time activity board will be returned to in situ by the spring force, and make the lock.
