A rotating stopper 12 is rotatably connected to the bottom shell 8. A third lever is provided on the rotating stopper 12. The third lever on the rotating stopper 12 abuts against the plastic safety 9.

The second torsion spring 13 is sleeved on the rotating stop block 12 , and one end of the second torsion spring 13 is connected to the fixed limiting plate 11 , and the other end of the second torsion spring 13 is connected to the connecting block 14 .

In the initial state, the magnetic deadbolt 4 extends out of the bottom shell 8. When locking the door, first insert the key matching the square hole iron fork 5 into the first square hole, and turn the square hole iron fork 5 clockwise. At this time, the first torsion spring 7 is deformed. Since the first lever abuts against the hooked end of the plastic insurance 9, the first lever drives the plastic insurance 9 to move laterally when it rotates. Since the plastic insurance 9 abuts against the third lever, the plastic insurance 9 drives the third lever to rotate when it moves laterally, thereby driving the rotating block 12 to rotate, and the rotating block 12 drives the second torsion spring 13 to rotate. The second torsion spring 13 squeezes the connecting block 14, so that the connecting block 14 moves longitudinally, and the connecting block 14 drives the sliding connecting rod 15 to move longitudinally, and the sliding connecting rod 15 drives the magnetic deadbolt 4 to move longitudinally. The magnetic deadbolt 4 is retracted into the bottom shell 8, and then the door is closed and the key is released. Under the action of the first torsion spring 7, the square hole iron fork 5 returns to the original position. Under the action of the second torsion spring 13, the plastic safety 9 and the magnetic deadbolt 4 both return to the original position. At this time, the magnetic deadbolt 4 is inserted into the magnetic snap-fit cover 1, and the two attract each other to lock the door. Then the key is inserted into the second square hole and the square hole block 10 is rotated counterclockwise. The second lever on the square hole block 10 abuts against the card slot on the plastic safety 9, thereby driving the plastic safety 9 to move to the side away from the square hole iron fork 5. After moving a certain distance, the hooked end of the plastic safety 9 is separated from the first lever on the square hole iron fork 5. At this time, the rotation of the square hole iron fork 5 is idling, which plays a safety role.

When the door needs to be opened, first insert the key into the square hole block 10, and rotate the square hole block 10 clockwise to make the plastic safety 9 move toward the side close to the square hole iron fork 5. After moving a certain distance, the first lever on the square hole iron fork 5 is re-engaged with the hook structure on the plastic safety 9. At this time, the square hole iron fork 5 is rotated clockwise to drive the magnetic tongue 4 to retract into the bottom shell 8 to achieve unlocking.

As an embodiment of the utility model, please refer to Figures 1 and 2, which also includes:

The plastic sleeve 3 is connected to the opening on the partition strip 6 to reduce the friction between the magnetic tongue 4 and the partition strip 6.

The working principle of the utility model is as follows: when locking the door, first insert the key matching the square hole iron fork 5 into the first square hole, and rotate the square hole iron fork 5 clockwise. At this time, the first torsion spring 7 is deformed. Since the first lever abuts against the hook-shaped end of the plastic insurance 9, the first lever drives the plastic insurance 9 to move horizontally when it rotates. Since the plastic insurance 9 abuts against the third lever, the plastic insurance 9 drives the third lever to rotate when it moves horizontally, thereby driving the rotating block 12 to rotate, and the rotating block 12 drives the second torsion spring 13 to rotate. The second torsion spring 13 squeezes the connecting block 14, so that the connecting block 14 moves longitudinally, and the connecting block 14 drives the sliding connecting rod 15 to move longitudinally. The sliding connecting rod 15 drives the magnetic deadbolt 4 to move longitudinally, so that The magnetic deadbolt 4 is retracted into the bottom shell 8, and then the door is closed and the key is released. Under the action of the first torsion spring 7, the square hole iron fork 5 returns to its original position. Under the action of the second torsion spring 13, the plastic safety 9 and the magnetic deadbolt 4 both return to their original positions. At this time, the magnetic deadbolt 4 is inserted into the magnetic snap-fit cover 1, and the two attract each other to lock the door. Then the key is inserted into the second square hole and the square hole block 10 is rotated counterclockwise. The second lever on the square hole block 10 abuts against the card slot on the plastic safety 9, thereby driving the plastic safety 9 to move toward the side away from the square hole iron fork 5. After moving a certain distance, the hooked end of the plastic safety 9 is separated from the first lever on the square hole iron fork 5. At this time, the rotation of the square hole iron fork 5 is idling, which plays a safety role.

When the door needs to be opened, first insert the key into the square hole block 10, and rotate the square hole block 10 clockwise to make the plastic safety 9 move toward the side close to the square hole iron fork 5. After moving a certain distance, the first lever on the square hole iron fork 5 is re-engaged with the hook structure on the plastic safety 9. At this time, the square hole iron fork 5 is rotated clockwise to drive the magnetic tongue 4 to retract into the bottom shell 8 to achieve unlocking.
