Detailed ways

As shown in Figures 1 to 2, the electromagnetic self-resetting keyless lock cylinder of the present application includes a door knob 1, a lock cylinder body 2, a toggle spring fixing bolt 3, a linkage bolt 4, a toggle tongue 5, a reset spring 6, Outside the door knob 7, outside the door positioning spring pin 8, dial reed 9, electromagnet sucker 10, electromagnetic coil 11, magnetizer 12, inside the door positioning spring pin 13, wherein, inside the door knob 1, outside the door knob 7 are preferably On the same axis, the more preferred linkage bolt 4 and dial tongue 5 are also located on the same axis. The door inner knob 1 and the outer door knob 7 are arranged on both sides of the lock core body 2 inside and outside the door, and the door inner knob 1 and the outer door knob The knob 7 is rotatably positioned in the lock core body 2 by means of the positioning spring pin 13 in the door and the positioning spring pin 8 outside the door, so that it remains in the fixed position of the lock core body 2 and can rotate. Segmental columnar structure, the front section of the door inner knob 1 (toward the outside of the door) protrudes as a boss, the cross-sectional area of the boss is smaller than that of the rear section, the outer surface of the boss is sleeved with a linkage bolt 4, and the outer surface of the linkage bolt 4 is connected with a dial tongue 5. The boss of the door knob 1, the linkage bolt 4, and the dial tongue 5 are connected by a polygonal structure, such as a hexagon, with clearance fit, and can move left and right along the axial direction. The boss has enough extension length to accommodate the linkage According to the requirements of the bolt 4 and its reciprocating axial movement, the end of the door knob 7 near the inner side of the door abuts on the dial tongue 5, and a concave hole is opened in the end, and the concave hole is designed to accommodate the interlocking bolt 4. At least a part, the length of the interlocking bolt 4 is to be able to withstand the torque transmitted when the subsequent door knob 7 performs the unlocking movement. When the interlocking bolt 4 is accommodated, the outer door knob 7 can form a polygonal connection with the interlocking bolt 4, for example Hexagonal, with loose fit, can move left and right along the axial direction, and a return spring 6 is arranged between the linkage bolt 4 and the door knob 1, so that the linkage bolt 4 can be kept separated from the door knob 7 only under the action of the reset spring 6 , the electromagnetic coil 11 is fixed in the lock core body 2 and connected to the external circuit. One end of the "T" shaped reed 9 with the electromagnet sucker 10 is located in front of the electromagnetic coil 11, and the other end is located behind the linkage bolt 4. The "T" foot of the piece 9 is fixed in the lock core body 2 by means of the spring fixing bolt 3.
