Mechanical cryptographic locks are generally composed of a lock body, a lock lever, a cryptographic mechanism, and a password input device. To prevent the test opening, the locking device can be designed to maintain a normally open state with the cryptographic mechanism. The design of the password input has two basic forms of touch and knob.
First, touch the password lock
Touching password lock is a mechanical password lock that touchs the number and enables the unlocked password into the lock, and the touch password lock is mainly made by the handle, digital button, distribution disk, digital disk, digital pole, digital marble, lock. Core, lock, etc.
The characteristics are: Hand touchs the digital button reset on the handle or the rotating handle to make the handle represent the number of reset to the reference line on the lock head and touch the button, the digital button moved on the handle, so that the rod moves The disc, the rod, the reset ring, the positioning rod, and the transmission rod contact in the reset lever, and the positioning teeth, the positioning rod and the digital disc are separated from the positioning teeth, the positioning gear and the distribution teeth. The spring disappears the number of rods, digital disk reset, and the lock stored in the lock; then input into the lock according to the correct password number of the password lock lock, touch the same digital button as the DI number, the digital button on the digital button The distribution bar is in contact with the distribution disk, first rotate the distribution disk, and the digital disk is moved, the digital disk moves,
The moving distance is related to the number of the digital button, and the contacts on the digital disc are in the order of the input unlock pass code number, or turn the handle, so that the number displayed on the handle is marked with the same number as the input digital number. After the reference line on the lock, press the button on the handle, contact the tab on the button to contact the distribution lever on the dispensing disk, turn the dispensing disk, and the digital disk is quantified, and the tuning ring on the button is again The tab or the tab is quantitatively moved, causing the internal bullets in the lock to release the self-locking of the latch to the lock core and the lock, one password input, according to such push, can enter a password one by one. The unit combination of the password lock its variant mechanism is composed of a cryptographic gear, a variable coded gear, a variable clamping disk, and the like, which is provided to control the password to control the latch and the unlocking member before the password is not affected. Transferring a differential force from an external force from the unlocking member, which is composed of a distinguished claw and a connecting clip, and a unique variation key or pull out the positioning pin when it is changed. .
Second, knob password lock
The knob type mechanical password lock structure unit includes decryption dense operation disc, a cryptographic wheel, and a connector.
Decrypting the end of the dense operation disc is coupled to the handle of the connector.
The lock pin is a protrusion attached to the latch, the end shape, size of the lock pin, the cryptographic ring, the cryptographic guard, the cryptographic slot, the fuse, etc. The password protector is sequentially distributed on the disk of the password wheel. The cryptographic circle is distributed with a cryptographic groove, the position of the cryptographic slot, and one of the federal positions on the password protection ring corresponds to the position of the cord rotation, the inner ring of the cryptography has a gear that meshes with the disk end of the connector. Password locking multiple password wheels control a lock pin, the number of passwords, high insurance factor.
The password protector and its firing on the password wheel can make cryptographic descriptions, increasing the insurance factor. The locking pliers controlling the password wheel prevents the password from the hand. The password rotating planet system is engaged with the ratchet, pawl, pawl fixation disc and two gears.
