Outward letter type order-changing code disc used for mechanical coded lock
The invention discloses an outward letter type order-changing code disc used for a mechanical coded lock. The outward letter type order-changing code disc is composed of a right-angled disc type main code disc body and a right-angled disc type auxiliary code disc body together. The right-angled disc type main code disc body is composed of decoding scale marks arranged on the outer circle of a disc ring provided with an outward disc opening, and circle-arrayed holes formed in an upper loop line and a lower loop line. The right-angled disc type auxiliary code disc body is linked to the main code disc in a loose-fitting mode and fixedly connected with a solid rotary knob. According to the outward letter type order-changing code disc, the user-friendly characteristic is injected into operations, so that an operator feels smooth and experiences enjoyment in the operations, and the secrecy of the lock is improved at the same time.
