A mechanical logic component such as mixed two-position component, wheel type of two-position component, displacement type of protector or controller, logic operator, mixed two-position counter, multiple digital lock, selectable type of antiprizing lock and unlock-test proof lock can be developed to be mechanical burglar proof devices such as sequencing burglar proof device, secondary protective burglar proof device of automobile, double-door burglar proof device, double-lock and double-alarm burglar proof door and secondary burglar proof new product with unlock-test and destructive unlock function.

The invention overcomes defects of the existing technology, and provides a locking lock with a built-in motor. Grooves or protrusions are arranged on four sides of the locking lock with the built-in motor, so that anti-theft performance of a key is further enhanced; with the built-in motor installed, a self-locking structure is achieved, and an anti-theft level is improved; and the lock cannot beopened internally without the key, and thus has high safety performance. According to the technical scheme, the locking lock with the built-in motor comprises the key, a motor assembly, a locking structure and a lock body, wherein the motor assembly and the locking structure are installed inside the lock body, the motor assembly is used to lock or unlock a handle, and the locking structure can only be unlocked through a matched key and prevent the lock body from being unlocked through rotating an internal handle. The locking lock with the built-in motor can be widely applied to the field of lock bodies.

A mechanical combination lock with electronic input is formed by connecting an electronic combination system to a mechanical combination system. The electronic combination system comprises an electronic input device, a control circuit, a drive circuit, a motor (6), and a power supply (5) that are connected in sequence. The mechanical combination system comprises a motor shaft gear (8), a transmission gear (12), a combination member, a limiting and connecting member, a knob (17), a knob shaft (20), and an unlocking device (15). Output of the electronic input device is connected to the control circuit. Output of the control circuit is connected to the drive circuit. Output of the drive circuit is connected to the motor (6). The motor shaft gear (8) is connected to a motor output shaft (9), and the motor shaft gear (8) is connected to and drives the combination member through the transmission gear (12); or, the combination member is directly mounted on the motor output shaft (9), and the limiting and connecting member has one end flexibly connected to the unlocking device (15) and the other end gap-fits the combination member. The knob shaft (20), the knob (17), the unlocking device (15) are components for connecting and fixing. The mechanical combination lock with electronic input has advantages of both a mechanical combination lock and an electronic combination lock, and is convenient, secure, reliable, abundant in combinations, and high in security level.
