Dial type
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 password 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.
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.
The difference between the dial type and the American "Shajin" type box
The dial-type full mechanical code lock is also a kind of box type mechanical code lock, which is similar to the "Shajin" and "Lurga" type box type mechanical code locks produced in the United States: they are all disc type mechanical code locks. There are control lock tongues, all of which are coaxial operation input passwords and open lock tongues. However, there is a big difference in the operation mode: the "Shajin" type box type mechanical code lock is connected to the active disk by the operation axis, and then the active disk is sequentially transmitted to drive other password disks, so the knob should be rotated a few times and then reversed when the password is input. In a few laps, you can enter your password repeatedly. The dial-type full mechanical code lock is a simple sequence dialer inside, which sequentially dials each password disc. From an external operation, it is similar to the operation of an old-fashioned dial-type telephone: starting from the beginning of the dial, turning the dial clockwise to a certain digit, and then returning 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 open the bolt.
In addition, there are other differences between them:
1. The lock tongue release bracket of the “Shajin†type box type mechanical code lock is always pressed on the password disc. When the password is input, the disc notch will rotate to the bracket and there will be a slight reflection. The experience is very rich and the experience is very high. People can find passwords based on this feature. The lock tongue unlocking bracket of the dial type full mechanical code lock is away from the password disc when the password is input, and only a small angle when unlocking is pressed on the password disc, and at this time, the password disc is stationary. of. Therefore, the probability of trying to test the password by hand is close to zero.
2, "Shajin" type box type mechanical code lock after closing the lock tongue, it is necessary to manually turn a few turns of the knob to dial the position of the password disc, and the dial type full mechanical code lock while opening the lock tongue, the inside The position of the password disc has been automatically dialed (reset), so you must re-enter the password after you close the lock to re-lock it, and you will not be allowed to keep the password.
3. The knob of the “Shajin†box type mechanical code lock should be engraved with 100 marks at 360 degrees, and only 3.6 degrees between each scale. Be careful when rotating the input. The dial-type full mechanical code lock only has 12 integer scales in less than half a circle, and there is a 12.5 degree interval between each scale. When entering the password, it is allowed to stay in the plus or minus 0.4 scale range of the scale. , both recognize the integer value entered into the scale. Therefore it is a quasi-digital input. Its available passwords are arranged in order from the minimum value to the maximum value, which can be randomly selected by the owner, without blind spots.
4. Dial the dial type Full mechanical code lock. When entering the password, turn clockwise from the starting point to the last one. It only needs 165 degrees, less than half a circle, then return to the starting point and enter the next password. During operation, the hand can hold the knob to enter all the passwords in a grip position. Unlike the "Shajin" type of box type mechanical code locks, it is necessary to reverse several circles and frequently reverse.
5. The number of digits of the "Shajin" box type mechanical code lock is fixed, and the number of digits of the dial type full mechanical code lock is variable. The maximum 6-digit password lock, the number of passwords can be selected between 0-6. If a 3-digit password is selected, it can only be limited to 3 digits. If you enter 4 digits, you cannot unlock it. This provides a wider choice for users in different locations.
At present, the 12-digit 6-digit password dial-type full mechanical password lock has 3.25 million passwords. If it is changed to 7 digits, there are 39.08 million passwords, and 8 digits have 430 million passwords. And all are optional passwords. If there is a special need for confidentiality, it is also possible to produce more scaled code locks as required.
