Abstract
A drive mechanism for a lock comprises a linear-moving sleeve (1), a conversion spring (2) and a rotating transmission component (3). The rotating component (3) is inserted into the linear-moving sleeve (1) that moves along the rotating component (3) in an axial direction. The conversion spring (2) is fitted onto the rotating component (3). The linear-moving sleeve (1) has symmetric protrusions (11). The rotating component (3) comprises an end (4) and a rotating bolt (5). The rotating bolt (5) is plugged into the clipping end (4). The conversion spring (2) has two curved ends (21) which are inserted into the groove (51) of the rotating bolt (5). The conversion spring (2) rotates in conjunction with the rotating of the rotating bolt (5) and the rotation movement is converted to linear movement along the rotating bolt (5).
Claims5
A drive mechanism for a lock comprising a linear-moving sleeve, a conversion spring and a rotating component, wherein the rotating component is inserted in the linear-moving sleeve that moves along the rotating component in an axial direction;
- the conversion spring is fitted onto the rotating component;
- and the linear-moving sleeve has symmetric protrusions to cooperate with the conversion spring so that the rotation of the rotating component causes the conversion spring and the linear-moving sleeve to linearly move in opposite directions, and wherein two curved ends of the conversion spring are inserted into a groove of the rotating bolt.
