Description

Lock Cylinder with Multiple Sections of Rotor}

The present invention relates to a lock cylinder having multiple rotors.

Conventionally, locks usually have only one rotor to recognize a key in the lock cylinder, which could easily be opened using a thin stick or wire. In addition, a button lock or a lock with a rotary number plate has been devised, but since there is only one rotor for recognizing keys, the above problems still exist.

In addition, when the user opens the lock using the key, in order to extract the key from the lock, it is necessary to remove the key by turning the rotor inside the lock again while inserting the key, which causes inconvenience in use.

SUMMARY OF THE INVENTION An object of the present invention for solving the above problems is to provide a lock cylinder having multiple rotors having a convenient operating structure while being difficult to easily unlock a lock from others.

The structure of the present invention for achieving the above object is characterized in that, in a conventional lock cylinder, having an external stator, a hollow lock seal inside the stator and at least three rotors inside the lock seal. As doing

Its main technical approach is to allow the two adjacent rotors to rotate in opposite directions while avoiding the extended rotational distance of the rotors during their rotation, and also torsion springs on the two adjacent rotors. This allows the individual rotors to automatically return to their original position after the lock is opened, allowing the key to be pulled straight out without manually rotating the key again in the opposite direction.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, a lock cylinder having multiple rotors of the present invention relates to a lock cylinder having an outer stator 10, a hollow lock chamber 11 and at least three rotors. ).

In the center of the lock chamber 11, three rotors of the first rotor 21, the second rotor 22, and the third rotor 23, according to a preferred embodiment of the present invention Has electrons Key holes 211, 221, 231 are formed at the center of each rotor, and the key holes 211, 221, 231 are alternately arranged before the key is inserted. Check slots 210 and 220 are formed on the outer circumferential surfaces of the first rotor 21 and the second rotor 22 so as to extend radially.

On the outer circumferential surface of the stator 10 meshed with the two check slots 210 and 220, two through holes 12 and 121 are drilled in a straight direction. Inside the through holes 12 and 121, two springs which respectively hold the two check rods 13 and 15 and the two check rods 13 and 15 inserted into the check slots 210 and 220, respectively. 14, 16) are formed. As shown in Fig. 2, the check slots 210 and 220 on the outer circumferential surfaces of the first rotor 21 and the second rotor 22 are placed in different directions before the key is inserted.

As shown in FIG. 2, the first step of opening the lock cylinder 1 is to insert the key 40 into the keyhole 211 of the first rotor 21. Since the key holes 211 and 221 of the first rotor 21 and the second rotor 22 are staggered from each other, as shown in FIG. 3, the distal end portion of the key 40 is the end surface of the second rotor 22. Will be cut off. In this step, the user rotates the first rotor 21 until the inner edge of the check slot 210 is constrained by the check rod 13. The two keyholes 211, 221 are then aligned, allowing for further insertion of the key 40 into the second rotor 22. In this step, the key holes 221, 231 of the second rotor 22 and the third rotor 23 are alternately arranged as shown in FIG. 4. Here, when the user is the inner edge of the check slot 22 formed on the outer circumferential surface of the second rotor 22 to the first rotor 21 and the second rotor 22 is restrained by the check rod 15. Rotate in the opposite direction. Then, the key 40 is allowed to be inserted into the third rotor 23 for rotating the cylinder, so that the lock blue 233 formed at the end of the third rotor 23 is rotated to open the door. Will be opened.

As described above, the user uses the key to rotate the first rotor 21 until it is aligned with the second rotor 22. The first rotor 21 and the second rotor 22 are rotated in opposite directions until they are aligned with the third rotor 23. Therefore, it is not necessary to form the check slots 210 and 220 too long on the outer circumferential surfaces of the first rotor 21 and the second rotor 22, which means that simpler mechanical manufacturing is possible.

As shown in FIG. 1, position holes 212 and 222 for insertion of a coil-shaped torsion spring 30 are formed at end surfaces adjacent to the first rotor 21 and the second rotor 22, respectively. . Further, adjacent end surfaces between the second rotor 22 and the third rotor 23 also have additional position holes 223 and 232 for insertion of the coil-shaped torsion spring 30, respectively. When the key rotates the first rotor 21, the torsion spring 30 located between the first rotor 21 and the second rotor 22 generates an elastic force and the second rotor 2 Another spring 30 also generates an elastic force when it rotates.

When the lock is opened, the key can be immediately pulled out of the keyhole, since the keyholes of the rotors are already aligned. After the key is removed, the rotors are reset to their original position by the elasticity of the torsion spring 30 between each rotor.

The above description relates to the design of three rotors. In the case of four rotors, a check slot is formed on the outer circumferential surface of the third rotor to cause the rotation having a direction opposite to that of the second rotor. In other words, two adjacent rotors rotate in opposite directions to avoid lengthening their rotation distance, which shortens the time for manufacturing the check slot.

The effect of the present invention having the configuration described above has the effect of preventing the lock from being easily opened by a thief or another person by providing a lock cylinder having at least three rotors, and the key is immediately removed from the keyhole. It is a very advanced invention with the effect that each rotor is automatically repositioned to their original position, bringing the convenience of operation of the user.
