Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The coded lock 01 of the safe case is a wheel disc type mechanical lock generally. The lock core of the lock 01 is composed of a plurality of concentric wheel discs 012, the wheel discs 012 have a hole in the center, and the hole has a small wheel disc convex part 0121. The key is inserted from this hole, and when the key is rotated, the key dials the boss 0121 of the wheel disc, and then drives the entire wheel disc 012 to rotate. The rim 012 has a groove at its outer edge, and the rim 012 has a latch at different positions. The key is provided with concave teeth which are staggered with a certain angle. In the locked condition, the disc protrusions 0121 on the inner sides of the different discs 012 are aligned, and at this time, the key can be inserted into the keyhole along the disc protrusions 0121. After the key is inserted into the keyhole, the key is rotated, and the key drives different wheel discs 012 to rotate for different times because the key has concave teeth staggered with a certain angle. When the outer edge grooves of all the wheel discs 012 are aligned and turned to the positions of the bolts, the bolts enter the grooves, and the keys are continuously turned, so that the wheel discs 012 drive the bolts to move, the bolts are connected with the bolts, and the bolts retract to open the lockset 01. The closing process is reversed.

When the key is lost, the key is difficult to open by using other keys, and the method of disassembling the safe by violence can be generally adopted.

According to the basic principle of this kind of lock, the utility model discloses an unlocking tool, the leading principle is, uses the instrument to stir each rim plate 012 alone, aligns and the set bar gets into in the recess until the recess of all rim plates 012, just so can open tool to lock 01. According to the different rotation angles of the tool, the angle difference of the key notch can be measured, and a new key can be manufactured again.

Fig. 1 and 2 are schematic diagrams showing the overall structure of a tool for unlocking and recovering a secret key. The unlocking deflector rod 02 is used for shifting the wheel disc 012 inside the lock 01. And a handle 03 for applying force to the unlocking lever 02. And the dial 04 is used for marking the rotation angle of the unlocking shift lever 02.

Wherein, the front working part 021 of the unlocking deflector rod 02 is of a hollow stepped shaft structure, and a bulge 0211 is arranged outside the shaft end. The hollow part 0212 is used for being matched and positioned with a central shaft 0101 inside the lockset 01, the shaft end outer protrusion 0211 is used for shifting a protrusion 0121 inside a wheel disc 012 inside the lockset 01, and the shaft end stepped part 0213 is used for being matched and positioned with a boss 0102 of the lockset 01.

The middle rod portion 022 of the unlocking shift lever 02 is of an optical axis structure, one end of the middle rod portion is used for being connected with the front end working portion 021, and the other end of the middle rod portion 022 is connected with the dial. Scale marks are uniformly distributed on the middle rod portion 022 and used for marking the axial forward and backward movement distance and reading the axial movement distance of the unlocking deflector rod 02 relative to a reference object (the reference object is a fixed disc). Because the lock core has a plurality of front and back wheel disc convex parts, the middle rod part needs to be moved back and forth so as to reach different wheel disc convex parts, and the scale mark at the position can record the distance of the middle rod part moving back and forth.

The handle 03 is an optical axis, is perpendicular to the unlocking shift lever 02, and is fixedly connected together through interference fit. The handle 03 is used to apply an axial force or a rotational torque. Handle 03 may also take other forms and arrangements, such as a rod-like structure that is concentric with lock release lever 02.

The dial 04 is used for marking the rotation angle of the unlocking shift lever 02. The scale discs 04 are respectively marked with evenly distributed scale lines. The dial 04 is divided into a fixed disk 041 and a movable disk 042. The fixed disc 041 is fixed in the using process, the movable disc 042 is fixed together with the handle 03 and the unlocking driving lever 02 and is in interference connection, the movable disc 042 rotates along with the rotation of the driving lever 02, and the relative rotation angle of the movable disc and the fixed disc measures the rotation angle of the unlocking driving lever 02.

The length of the middle rod part depends on the distance between the outermost surface of the safe door and the lock, the safe door of the safe has certain thickness for the sake of safety, the lock is positioned in the safe door, and when the tool is used, the tool is positioned outside the safe, the fixed plate is attached to the safe door, and the middle rod part extends into the safe door to reach the inside of the lock core, so that the length of the middle rod part depends on the distance between the outermost surface of the safe door and the lock.

Specifically, the recorded rotation angles of the plurality of groups of unlocking shift levers 02 are the passwords of the keys of the lock 01. Based on this code, the key can be reconfigured.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
