Description
Technical field
The present invention relates to a kind of transmission device of automatic locking, a kind of oscillating motion that is used for the door leaf opening-closing process that concrete is changes the transmission device that straight line that the dead bolt member that is suitable for described automatic locking stretches out moves into.
Background technology
At present, the automatic locking of use, electric control lock, the mode that its dead bolt kinergety obtains mainly contains following several: a kind of is to obtain by hand, this mode difficulty reaches electric control and finishes its entire work process; Another kind is to touch doorframe by the oblique tongue of the transmission on the electric control lock to obtain the required energy of dead bolt motion, though this mode can be used automatically controlled breakdown, resistance is bigger at closing time, is not suitable for having the complicated lockset of multidirectional lock point; Having a kind of again is that the energy that produces when door is closed is delivered on the dead bolt by transmission mechanism, thereby makes dead bolt obtain to lock out required energy.
A kind of transmission mechanism of lock is disclosed at Chinese patent literature CN2436619Y, this technical scheme is by door leaf, driving member, doorframe, hinge, composition such as lock body and dead bolt, in door leaf, be provided with a driving member that can slide vertically, the one end stretches out door leaf and joins with hinged doorframe, one groove is arranged on the driving head on the driving member, it flexibly connects through the positioning head and the accumulation of energy conduit of unlock key, the accumulation of energy conduit is a hollow core structures, one driving key back-moving spring is housed in it, the blind end of accumulation of energy conduit is enclosed within on the dead bolt, the other end is set with driving head, the accumulation of energy conduit is connected with driving head by unlock key, driving head and driving member back-moving spring join, the active force of driving member back-moving spring can slide driving member through driving head outside door leaf, have one to reset the crown on back-moving spring on the unlock key, the other end of back-moving spring is fixed on the lock body, the purpose of back-moving spring is to reset after unlock key is towed out, be set with an energy-storaging spring on the accumulation of energy conduit, its active force acts on respectively between accumulation of energy conduit and the dead bolt; One guide peg is arranged in the dead bolt in addition, the afterbody that an end that is with dead bolt back-moving spring guide peg on it passes dead bolt is fixed on the lock body, dead bolt can slide before and after guide peg, and the dead bolt back-moving spring is stuck between dead bolt and the lock body, and its active force can make dead bolt withdrawal lock body.At closing time, door leaf rotates around the hinge fulcrum, angle between door leaf and the doorframe is reduced, at this moment, driving member is along door leaf toward interior slip, driving head on the driving member promotes the accumulation of energy conduit through unlock key, because of the two ends of accumulation of energy conduit are actively set on dead bolt and the lock body, so the accumulation of energy conduit is by the plush copper compress energy storage spring on it, the effect of energy-storaging spring can storage power lock out dead bolt exactly, and it can be contained on any position between doorframe and the dead bolt, because the power during the energy-storaging spring design is greater than the power of dead bolt back-moving spring, lock out needed strength so dead bolt has been obtained, can lock as long as control.In the time of need unblanking, the positioning head of unlock key is opened from the groove of driving head, thereby disconnected being connected of driving head and accumulation of energy conduit by control head, the accumulation of energy conduit flicks under the effect of energy-storaging spring, the elastic force of energy-storaging spring disappears, under the effect of dead bolt back-moving spring power, in the dead bolt withdrawal lock body; When opening the door, driving member stretches out the door leaf certain-length under the effect of driving member back-moving spring, and unlock key is under the effect of back-moving spring, and resetting again connects driving head and accumulation of energy conduit, thereby has reached whole transmission process.
