Description
Technical field
The present invention relates to a kind of door lock, referring in particular to and need not to rotate key is exactly the door lock that makes the locking of master lock tongue.
Background technology
General lockset is locked all needs the rotation of artificial mechanism key, master lock tongue except latch bolt is locked, and using is not namely easily, and the user forgets the words of with key, locking, just be equivalent to whole door leaf and only gone up lock point of latch bolt, non-anti-theft.
Chinese patent literature CN 201771269U discloses a kind of door lock assembly, and it mainly comprises housing, be installed on the lock core assembly of lower housing portion, be installed on the Handleset on housing top, housing middle part is equipped with the latch bolt assembly, and the latch bolt assembly comprises the latch bolt and the oblique tongue rod that is connected with latch bolt of opening in order to limiting door that can stretch out from housing, be fixed with the square piece of the outstanding body of rod on oblique tongue rod, in the housing of lock core assembly top, the slide plate that can horizontally slip is installed, the left end of slide plate extends upward, the top of slide plate comprises the first projection and the second projection, in the housing of slide plate top, welding or riveted joint have hinge post, the latch bolt plectrum is rotatably mounted on hinge post by centre bore, the latch bolt plectrum comprises two jags, wherein the first jag extends to the left of square piece to lower right, the second jag extends to the left of struck side to upper right side, on the right-hand housing of slide plate, the tight locking plate that can slide up and down is installed, the back-moving spring that resets downwards of the tight locking plate that moves is installed to make on tight locking plate, the stage casing of tight locking plate is outstanding to the right, form protuberance, the top of protuberance bends forward, tab before forming, have square hole on front tab, under the door lock opening, the first projection of slide plate puts in square hole on front tab.When the handle that turns clockwise, thumb wheel turns clockwise, and the second jag of the struck side of thumb wheel and latch bolt plectrum is interfered, the latch bolt plectrum rotarily drives the first jag and is rotated counterclockwise, the first jag square piece right-hand with it interfered, and square piece moves right, and drives latch bolt and shrinks back in housing.When discharging rotary handle, latch bolt under the effect of reduction torsion spring, is stretched out left again outside housing, and oblique tongue rod drives square piece and stirs the first jag left simultaneously, and the first jag drives the rotation of latch bolt plectrum, and it is resetted.
Under this state, rotate the key in the lockhole that puts in the lock core assembly, key band movable lock core, the lock core plectrum is rotated counterclockwise, the lock core plectrum rotates the jack-up that at first protuberance of tight locking plate made progress, and, along with moving on front tab, breaks away from the square hole on first projection the past tab.The lock core plectrum of rotation then and slide plate to the lower process interference, under this interference effect, slide plate is moved to the left.When slide plate moves to the leftmost position, tight locking plate moves down under the effect of back-moving spring, and the square hole on the front tab of whereabouts entangles mobile the second projection of coming just.At this moment door lock changes lockup state into.This type door lock assembly needs the rotation key of artificial mechanism when locking, the user forgets with key and locks, and just is equivalent to whole door leaf and has only gone up lock point of latch bolt, and is non-anti-theft, and can shake when visiting in pass.
Summary of the invention
The object of the invention is to overcome above shortcomings in prior art, and a kind of rotation key that does not need artificial mechanism is provided, the master lock tongue is locked, easy to use, safe without mechanism for locking up and be not afraid of the lockset of stealing.
