An electric lock for doors has a housing with an opening, including a first catch and a second catch, an overlap formed by which enables the operation of the present invention. A blocking element connected to a driving device is displaced between an opening position and a closing position whereby the blocking element would stop the first catch from turning when being in the closing position, therefore controlling the turning of the second catch, rendering the opening a locked status and locking up the latch; when the blocking element is in the opening position, the blocking against the first catch would be eliminated, therefore turning the second catch together and rendering the opening an unlocked status, allowing the latch to be unlocked. |

1. An electric lock for doors comprising:
a housing having an opening on the side wall thereof for a latch to enter; a first catch arranged at one side of said housing, having a first inner arm and a first outer arm, the latter of which is near said opening; a second catch arranged at the other side of said housing correspondingly to said first catch, having a second inner arm and a second outer arm; wherein the end of said second inner arm partially overlaps the end of said first inner arm, forming an overlap, and a hedge for locking the latch is formed by said first and second outer arms; a driving device disposed inside said housing and near the first catch, having a driving stick to stick out and withdraw; and a blocking element to be displaced between an opening position and a closing position by said driving stick; whereby the blocking element would stop the first catch from turning when being in the closing position, and the first catch would stop the second catch from turning due to the arrangement of said overlap, rendering the opening a locked status; when the blocking element is in the opening position, it would allow the first catch to turn and control the turning of the second catch as well, rendering the opening an unlocked status. |
