Utility model content
The deficiency existing for prior art, the utility model provides a kind of and skew bolt lock can be fixed in housing, the door knob lock of long service life.
For achieving the above object, the utility model provides following technical scheme: a kind of door knob lock, comprise housing, be arranged on the lock core assembly in housing, Handleset and latch bolt assembly, described lock core assembly, Handleset is connected with described latch bolt assembly respectively, described Handleset comprises and is placed in housing thumb wheel and is arranged on housing for driving the handle of thumb wheel rotation, described latch bolt assembly comprises the latch bolt of opening in order to limiting door that can stretch out from housing, the oblique tongue rod being fixedly connected with latch bolt and be fixed on oblique tongue rod upper reset spring, the latch bolt plectrum that has been connected between described oblique tongue rod and thumb wheel, described latch bolt bilateral symmetry is provided with stopper slot, in described housing, be provided with for the latch bolt chamber in latch bolt indentation housing, described housing both sides are provided with fixedly latch bolt and remain on the latch assembly in latch bolt chamber.
By adopting technique scheme, this door knob lock rotary handle when opening drives thumb wheel, moving to right and then driving latch bolt to contract of thumb wheel conflict latch bolt plectrum and control oblique tongue rod realizes the unlatching of this door knob lock in latch bolt chamber, in latch bolt bilateral symmetry is provided with stopper slot and housing, latch assembly and the cooperation by have between the two realized the locking of latch bolt in the latch bolt chamber in latch bolt stationary housing, solved the problem existing when door knob lock is often arranged in room that someone comes in and goes out or communal facility, but Ru Yi office is example door need to close, do not need again to lock, as long as pull out latch assembly and lock after working in a day finishes, this door knob lock fixes in housing latch bolt chamber by skew bolt lock, solved frequent operation Handleset, easily cause door knob lock infringement, significantly promote the application life of door knob lock.
The utility model is further set to: described latch assembly comprise conducting latch bolt chamber slot, the latch on slot is set and is fixed on stretching chain on housing, described stretching chain one end is fixed on housing, the other end is fixedly connected with described latch.
By adopting technique scheme, the function of latch assembly realizes slides on slot by latch and makes the end card of latch be set to realization locking in latch bolt chamber to latch bolt in the stopper slot of latch bolt, the setting party of stretching chain the plug of latch, also effectively avoid coming off of latch simultaneously.
The utility model is further set to: the cross section of described stopper slot is curved, and the end of described latch is provided with the spherical protuberance suitable with described stopper slot.
By adopting technique scheme, the setting that the end curved and latch, cross section of stopper slot is spherical protuberance, weakened the spacing power of slot to latch bolt, avoid sometimes having forgotten to extract latch plate fixed handle with sudden force again, cannot make the lasting effect energetically of latch bolt retraction latch bolt chamber internal cause and be out of shape, lost efficacy, thereby causing scrapping of whole door knob lock.
The utility model is further set to: described lock core assembly comprises lock core, slide plate and stay, one end of described slide plate has been wholely set boss, described stay is provided with blocked hole, and described lock core comprises lockhole and moves and make the boss card on slide plate establish the slide block in the blocked hole on stay for stirring the relative housing radial direction of slide plate.
By adopting technique scheme, the setting of lock core assembly is to guarantee that latch bolt is fixed on outside housing, realize the lock function of door knob lock, this function is inserted in lockhole by a key and is turned clockwise to drive slide block and slide plate is moved to the left and props up latch bolt, realizes locking when the boss card on slide plate is established on the blocked hole on stay.
The utility model is further set to: described housing is provided with for limiting the articulated column of latch bolt plectrum.
By adopting technique scheme, the arranging to have realized of articulated column fixed and limits latch bolt plectrum, avoids because of the excessive inefficacy that causes latch assembly of latch bolt plectrum reset force, and the latch assembly of guaranteeing is spacing to latch bolt.
