A second magnetic ring 14 is arranged on the end face, opposite to the spring sleeve 7, of the lock beam 9, and the magnetic pole of the second magnetic ring 14 is opposite to that of the first magnetic ring 8; a buffer sheet 15 is arranged on the periphery of the second magnet ring 14; a wear-resistant layer 16 is attached to the outer side surface of the spring sleeve 7; a positioning bulge 17 is arranged on the top surface of the positioning pin 12, and an inclined tangent plane 18 is arranged on the side surface, facing the spring sleeve 7, of the positioning bulge 17; a cut-in groove 19 is formed in the position, corresponding to the positioning protrusion 17, of the lock beam 9, and the positioning protrusion 17 is tightly connected with the inner side face of the cut-in groove 19 through a cut face 18; a plurality of arc-shaped anti-falling grooves 20 are formed in the inner side surface of the lock cylinder groove 2, and all the anti-falling grooves 20 are vertically and uniformly distributed; anti-falling lugs 21 are arranged at positions, corresponding to the anti-falling grooves 20, on the lock cylinder 3, and each anti-falling lug 21 is arranged in the corresponding anti-falling groove 20; the marble group comprises marble springs 22, and flat marble 23 is sleeved on the marble springs 22; one side of the flat head marble 23 close to the lock core 3 is connected with a round head marble 24, and the round head marble 24 is arranged on the lock core 3 in a sliding manner; a first moving channel 25 is arranged on the side surface of the lock cylinder groove 2 corresponding to the positions of the pin spring 22 and the flat pin 23; a second moving channel 26 is arranged at the position, corresponding to the round-head marble 24, on the lock core 3; a moving groove 27 is arranged at the position of the lock body 1 corresponding to the sliding position of the lock beam 9; anti-falling rings 28 are mounted at both ends of the lock beam 9.

The working principle is as follows: when the lockset is locked, firstly, a correct key is inserted into the lock cylinder 3, the teeth on the key correspond to the round head marbles 24 at different positions, the teeth on the key can push the corresponding round head marbles 24 to move towards the flat head marbles 23, and push the flat head marbles 23 to move and then compress the marble springs 22, and finally all the flat head marbles 23 just leave the lock cylinder 3, and all the round head marbles 24 just are in the lock cylinder 3; then, the lock core 3 is rotated by a key, the anti-falling lug 21 and the positioning piece 4 are driven to rotate together after the lock core 3 rotates, wherein the anti-falling lug 21 can move along the anti-falling groove 20, so that the lock core 3 can be ensured to be stably installed in the lock core groove 2 while the lock core 3 rotates, and the anti-falling groove 20 can limit the rotating angle and the rotating direction of the lock core 3; after the positioning piece 4 rotates, the depth of the integral positioning piece 4 is different because the bottom surface of the positioning piece 4 is arranged in an inclined shape; after the positioning element 4 rotates, the contact area between the side surface of the positioning element 4 and the inner side surface of the positioning channel 13 on the positioning pin 12 is gradually increased, so that the positioning element 13 pushes the positioning pin 12 to move downwards in the positioning slot 10, the positioning protrusion 17 on the positioning element 4 is separated from the bottom surface of the spring sleeve 7, and the spring sleeve 7 can move left and right; meanwhile, the positioning pin 12 compresses the positioning spring 11 in the process of moving downwards, so that the positioning spring 11 has an upward pushing force.

Then, the lock beam 9 is pushed into the lock beam groove 5 and moves towards the lock beam spring 6 along the spring sleeve 7, wherein after the lock beam 9 is contacted with the spring sleeve 7, the lock beam 9 can be stably connected with the spring sleeve 7 by utilizing the mutual attraction between the first magnet ring 8 and the second magnet ring 14, and the lock beam 9 can compress the lock beam spring 6 through the spring sleeve 7 without continuously pushing the lock beam 9, so that the spring sleeve 7 has a force capable of pushing the lock beam 9 to unlock; when the lock beam 9 is moved to the right position and then reversely rotated by the key, at the same time, the lock cylinder 3 can drive the positioning part 4 to reversely rotate, so that the contact area of the side surface of the positioning part 4 and the inner side surface of the positioning channel 13 on the positioning pin 12 can be gradually reduced, so that the positioning part 13 moves upwards under the thrust action of the positioning spring 11, the positioning part 13 can drive the positioning bulge 17 to move upwards together in the process of moving upwards, and finally, the tangent plane 18 on the positioning bulge 17 slides into the cut-in groove 19 at the end part of the lock beam 9, thereby completing the locking work of the lock beam 9 and completing the locking work.

The unlocking process is opposite to the locking process, and when the limit of the positioning bulge 12 on the lock beam 9 disappears, the lock beam 9 can be pushed out of the lock beam groove 5 under the action of the lock beam spring 6, and then the lock beam 9 is pulled outwards, so that the lock beam 9 is separated from the spring sleeve 7, and the unlocking work can be completed; when the lock beam 9 and the spring housing 7 are tightly attached to each other under the action of the first magnet ring 8 and the second magnet ring 14, because the force for pushing the lock beam 9 and the attraction force between the first magnet ring 8 and the second magnet ring 14 increase, a certain impact force is generated when the lock beam 9 and the spring housing 7 are attached to each other, and at this time, the arrangement of the buffer sheet 15 can buffer the impact force and the counter impact force generated between the lock beam 9 and the spring housing 7 to a certain extent, so that the damage to the lock beam 9 and the spring housing 7 is reduced; meanwhile, the wear-resistant layer 16 on the side surface of the spring sleeve 7 is matched, so that the wear between the spring sleeve 7 and the lock body 1 can be reduced, and the service life is further prolonged to a certain extent.
