Household electric and mechanical dual-controlled intelligent lock

A household electric and mechanical dual-controlled intelligent lock, which comprises a mechanical clutching structure and an intelligent electronic control structure, wherein:

• the mechanical clutching structure comprises a locking head, a springback lock tongue, a first round rotary table and a fixed seat, wherein:
• the springback lock tongue is fixed on the fixed seat, an end portion of the springback lock tongue extends outside the fixed seat, a first arched guide rail which is fitted with the first round rotary table is located on one surface of the springback lock tongue, the locking head is connected with the springback lock tongue through the first round rotary table, so that when a key is inserted into the locking head for rotating to drive the first round rotary table to rotate, the end portion of the springback lock tongue is retracted into the fixed seat;
• the intelligent electronic control structure comprises a PCB (printed circuit board), a motor, a scalable suite and a second round rotary table, wherein:
• the PCB is electrically connected with the motor, one end of the scalable suite is fixedly connected with the motor, the other end of the scalable suite is fixedly connected with the second round rotary table, a second arched guide rail which is fitted with the second round rotary table is located on the other surface of the springback lock tongue;
• the PCB controls the motor to work, the scalable suite drives the second round rotary table to rotate, so that the end portion of the springback lock tongue is retracted into the fixed seat.
