Currently we are only safe to mechanical higher than the level of security of electronic safety cabinet, there are a lot of people will study mechanical principles and to find safe unlock unlock method. In fact, this is a very meticulous thing, but also your understanding of the numbers. The following small series will satisfy everyone's curiosity and tell everyone the principle and method of unlocking the mechanical safe.
Principle and method of unlocking mechanical safes:
The mechanical lock of the mechanical safe lock is based on the inside of the lock and has a series of wheel discs. The number dial located outside the lock, if rotated in order, can overlap the gaps on the wheel discs. When the cross lever bolt on the latch is inserted into the gap, the bolt can be retracted and unlocked. The scale on the dial can indicate whether the position of the notch on each wheel disc is correct. If the gap on each wheel disc is not in a line, the code lock will not open.
First, the mechanical password safe (box) of the 100th dial is used as the ratio. We divide the number dial of the 100 into two, and start from the middle to push the code, which is the 50 mark. The first step is first. When the hour hand turns the dial three times or more to the 50 mark stop, the alignment tick mark <the tick mark is at the positive direction of 12 o'clock> then turn the counterclockwise one turn to the 50 tick mark to stop <When we turn the 45 mark counterclockwise There will be a more obvious hand feeling, it is the contact of the driving point, that is, the driving point of the first wheel and the second wheel is in contact with the driven point, and the position of the two driving points is also It is around five scales.
It should be clearly stated here that this 50-scale number is the number of the first round disc that we assume is positioned. When we turn the dial one turn counterclockwise to the 50-digit number, we add the 45-digit number. Why should we add it to the 45-scale? No. It is clear that we are looking for and assuming the tick mark of the second round of discs, which is what people often say, which is more specific, that is, the first set is brought to the second set. The distance of the point <how many distances there are.
It has been discussed in the previous chapters, but it is necessary to repeat here that the driving points of the stamped disc wheel are fixed, both at 12 o'clock and 6 o'clock, at a distance of 50, and then Subtract the position of the five scales of the two driving points, that is, 45 scales, so add 45 scales.
Seeing everyone here is clear about the principle and method of unlocking mechanical safes? If you still want to know more, please continue to pay attention to this website.
