Lock knowledge: dial code type full mechanical password lock principle
A combination lock is a type of lock that is opened with a series of numbers or symbols. Passwords for password locks are usually just an arrangement rather than a true combination. Some code locks use only one turntable to turn a number of discs or cams inside the lock; some locks are a set of several numbered dials that directly drive the inside of the lock. Dial type mechanical lock Dial-type full mechanical password lock principle This is a large-key, high-reliability, all-mechanical code lock without electronics. It operates in a unique way, similar to the dialing of an old telephone - starting from the beginning of the dial, turning the dial clockwise to a digit, then backing to the starting point, a password is entered. Repeat this until the last password is entered, and then turn the dial counterclockwise from the starting point to unlock. At the same time as unlocking, the internal has been reset, so after the dial is returned to the starting point, the password must be re-entered to unlock, and there is no need to consider the internal reset problem. If you enter the wrong password, turn the dial counterclockwise (virtual unlock) to reset internally and then re-enter the password. In this kind of password lock, the six-digit password can have more than 2.98 million sets of passwords for the owner to change at will, and the confidentiality is extremely high. The optional cipher suites are arranged in series, which is convenient for selecting passwords that are easy to remember. The basic products that have been developed so far, the number of passwords and the number of passwords can also be redesigned according to the needs of users. It is also possible to add an alarm interface to the user. The advantages of this combination lock: 1, no key, no power, no battery, no waste. 2, full mechanical structure, can withstand the harsh external environment, a wide range of uses. 3, the operation is simple, the unlocking time is relatively short, and the average unlocking time is about 15 seconds. 4, the actual amount of password is large, the security performance is high, and the probability of trial unlocking is almost zero. 5, the structure is simple, strong and reliable. From the historical law of technological development, in the case of similar functions, simple and reliable things always replace complicated things, and it is exactly what is simple and complicated. Therefore, it is a popular and practical new product, which should replace the traditional disc type mechanical code lock and some electronic code locks. The dial-type full mechanical code lock is widely used in safes, safes, filing cabinets, anti-magnetic fireproof cabinets, security doors, silver door, warehouse doors, doors, civil doors and mechanical jamming mechanisms. It can replace the existing traditional disc type mechanical code lock and some electronic code locks. Provide an opportunity for the update of certain products. Dial-type full mechanical password lock principle Due to the popularity of electronic technology , many products are proud of adopting electronic structures. However, in some places, electronic products do not have an absolute advantage, but mechanical products or electromechanical hybrid products are more practical. To give two examples: First , the ignition device of the gas stove . In the early days, the igniter of the transistor was popular, but it was not resistant to moisture, easily damaged, and could not be separated from the battery. For a long time, the mechanical (piezoelectric) fire-fighting device that relies on the hand to twist the energy storage of the knob reveals its superiority--simple and practical, becoming the mainstream of the gas stove igniter. Second, the rearview mirror of the car and the rear door peeper of the bus (single car) have all been replaced by electronic monitors, but people find that the traditional rearview mirror and the ordinary rearview mirror above the bus driver The observation effect is not worse than the electronic monitor, which is simpler and more practical. In fact, in the traditional industry, it is also possible to find a more insured investment than the so-called "new economy" but with no profit. The combination lock is not a product that is frequently used. It can be said to be a semi-static product, which is more practical by mechanical means. However, the amount of passwords in electronic mode is large, and people feel that they are safer. The password of this patented product is close to the electronic code lock, and the operation is much faster than the traditional mechanical code lock. It is simple and practical. It can be the mainstream of high-grade password locks like the previous two cases.
