An electronic-mechanical dual control lock comprising an electronic control mechanism, a mechanical control mechanism, a half gear (2), a cam (3), a rotary plug (1), and a rotary tongue (12). The electronic control mechanism comprises an electronic actuating part (8) and an engaging groove gear (4). The electronic actuating part (8) is meshed with the engaging groove gear (4). The bottom surface of the engaging groove gear (4) fits the bottom surface of the cam (3). The mechanical control mechanism comprises a mechanical actuating part and the half gear (2). The mechanical actuating part is meshed with the half gear (2). The cam (3) is driven respectively and independently by the engaging groove gear (4) and the half gear (2). The rotary plug (1) comprises a rotary shaft and a plug body. The rotary shaft is arranged at one extremity of the plug body and is engagingly connected onto the cam (3). The plug body is a cylinder provided at a side thereof with a groove. The groove of the plug body of the rotary plug (1) can rotate into or out of the motion trajectory of the rotary tongue (12). The electronic-mechanical dual control lock switches therein between a mechanical structure and an electronic structure and is structurally simple, convenient, and practical. |
