Mechanical password lock is a security device that does not require power support and controls the opening and closing of locks through specific mechanical structures and password combinations. It relies on stable and reliable performance, as well as a simple and direct operation method.
The mechanical password lock is mainly composed of a password disk, lock cylinder, lock tongue, gear transmission mechanism, and a series of control components inside. When the user rotates the password disk, the password disk drives the internal gears to rotate, and each gear corresponds to a password digit. After correctly entering the pre-set password combination, the specific tooth profiles of the gears will match each other, pushing the control components inside the lock cylinder to move to a specific position, thereby releasing the locking restriction on the lock tongue. At this time, the lock tongue can be retracted by external force to achieve unlocking; If the password is entered incorrectly, the gears will not fit correctly, and the lock tongue will be firmly locked and unable to be opened.
Structural composition
1. Password disk: usually located outside the lock, convenient for users to operate. The surface of the password disk is engraved with numbers or characters, and users can enter their password by rotating the password disk.
2. Lock core: As the core component of a lock, the lock core contains a complex mechanical structure inside, which is used to identify passwords and control the movement of the lock tongue.
3. Lock tongue: a key component responsible for locking and opening locks, commonly available in two types: straight tongue and diagonal tongue. In the locked state, the lock tongue extends and is embedded in the lock catch to prevent the door or cabinet door from being opened; When unlocking, the lock tongue retracts, allowing the door or cabinet door to open freely.
4. Gear transmission mechanism: Connect the password disk and the lock cylinder, transmit the rotational motion of the password disk to the lock cylinder, and achieve password recognition and control through different combinations of gears.
5. Control component: composed of multiple mechanical parts, it controls the locking and unlocking status of the lock tongue according to the password input situation.
