The use of safe mechanical locks 1. The principle of blade locks for mechanical blade locks is to use a tooth with different angles of the bevel on the key to rotate and align the blades with different angle changes in the lock cylinder, so as to realize a kind of lock that the lock core rotates and opens. .
When using, please pay attention to the insertion direction of the key: The key shank must be vertical, and the raised key (key correctly inserted into the direction mark) on the key shank can be inserted into the keyhole. After confirming that the key is fully inserted, turn the key clockwise to unlock it. Do not force the key to unlock when the key is not inserted in the end, resulting in the failure of the key stuck in the lock cylinder to pull out or twist the key. The key cannot be pulled out during rotation, and the key can only be pulled out after turning the key counterclockwise to lock it.
Because the lock core adopts the non-spring leaf structure, if the blade lock is subjected to relatively strong vibration and impact, the blade can easily rotate within a rotation range of 90 degrees, resulting in that the key cannot be inserted. Therefore, the lock box is locked when the safe and cabinet are delivered from the factory. A plastic bar similar to the key is inserted in the hole to prevent the blade from rotating freely. Please save this plastic rod, when moving, transporting safes, cabinets, or when you do not use safes or cabinets for a long time, insert the plastic rods into the keyholes to prevent the blades from turning freely and prevent foreign materials from entering the keyholes.
2. The use of the mechanical pin lock The principle of the pin lock (Yale lock) is to use the different teeth of the triangular notch in the key to align the cylindrical pin with different length change in the lock core, so as to realize the rotation of the lock pin. Kinds of locks. The direction of its marbles is usually up and down vertical, arranged longitudinally, and the keyhole is generally located in the center of the lock cylinder. Jebold King uses a double-column lock cylinder to lock the composite ball lock. It uses different densities of the round bullet holes on the key to align cylinders of different length in the cylinder and release the cylinder. The lock of the column lock block enables a type of lock in which the lock cylinder rotates to open. It has two rows of marbles. The direction of the marbles is horizontal and vertical. The keyholes are located to the right of the lock cylinder.
When using, please pay attention to the insertion direction of the key: the key shank must be vertical, and the hole of the lock cylinder head must be aligned with the hole on the lock cylinder to insert the key into the lock hole. After confirming that the key is fully inserted, turn the key clockwise to unlock it. Do not force the key to be unlocked when the key is not inserted in the end, causing the key to be broken. The key cannot be pulled out during rotation, and the key can only be pulled out after turning the key counterclockwise to lock it.
3. Use of mechanical code lock The mechanical code lock we use now is actually a cryptographic device. It is through the rotation of a certain turning piece, and the rotation piece is driven by the transmission piece on the rotating piece to rotate, so that the notch in each rotating piece is repeatedly aligned and aligned in the same position through a specific rotation mode, ie, the code lock is opened. . Changing the position of the transmission on the rotor changes the password.
Four rotary mechanical locks, it has four passwords, its operation method is as follows:
1 Turn the dial dial clockwise (right) to stop turning the number dial when the first password is aligned for the fourth time (as long as four or more times are possible) with the open mark (the score line at 12 o'clock).
2 Turn the dial counterclockwise (left), and when the second password is aligned with the opening mark (crotch at 12 o'clock) for the third time, stop turning the number dial.
3 Turn the dial dial clockwise (right) to stop turning the number dial when the third password is aligned with the opening mark (the score line at 12 o'clock) for the second time.
4 Turn the dial counterclockwise (left) to stop turning the number dial when the fourth password is aligned with the opening mark (the score line at 12 o'clock) for the first time.
At this time, the gaps on the four rotary plates are aligned and the code lock is opened.
The method of unlocking the code lock can be memorized by the operation button. The direction of the rotation number dial is "Shun, Reverse, Shun, Reverse", and the number of rotations of the number dial is "4, 3, 2, 1". When turning the number dial, you cannot turn left or right, nor can you make more turns or fewer turns. If you make a mistake, you must restart the operation. Need to change the password, you must ask a professional to replace, forget the password can be based on the product number and product model to the factory for inquiry.
4. Use of mechanical emergency locks Mechanical emergency locks are used to open the electronic code lock when the electronic code lock fails. The emergency lock used by King Jewels is also a kind of marble lock, but its cylindrical marble is not arranged in a straight line, but is arranged in a circle, and the lock is aligned through a tooth with a different semi-circular length on a round tubular key. A cylindrical lock is formed by changing the length of the cylinder in the circumference of the core so that the lock cylinder rotates and opens.
When using, please pay attention to the direction of insertion of the key: the protrusion on the key tube must be aligned with the notch in the lock head to insert the key. After inserting the key, you must push the key inward and turn the key counterclockwise (leftward). The electronic code lock can be opened.
Mechanical emergency locks are generally concealed installation. Please refer to the product user manual for details on the specific location and usage. Remember that mechanical emergency keys cannot be used as normal safes and cabinets.
