This door latch structure is more complicated, can not on kissing gate frame, install, and environment as narrower in doorframes such as shower doors is used, and installing space demand is large.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind ofly on narrower doorframe, to install, simple in structure, the interior Door lock that installing space is little.
The purpose of this utility model can realize by following technical proposal: a kind of interior Door lock, comprise lock housing, be arranged on the lock core assembly in lock housing, large bolt component and little bolt component, the handle assembly that runs through lock housing and can drive large bolt component motion is also installed in lock housing, it is characterized in that, described lock housing is rectangular tabular, and described large bolt component and little bolt component are stretched out by the narrow limit of lock housing; Described large bolt component comprises dead bolt mount pad, the dead bolt pin and the large dead bolt that is arranged on dead bolt pin end that run through dead bolt mount pad, on described dead bolt mount pad, big lock tongue spring is also installed, the described big lock tongue spring other end passes dead bolt mount pad and leans in lock housing; In described lock housing, torsional angle is installed, described torsional angle connects handle assembly, and one end of described torsional angle is erected on large bolt component, and described torsional angle rotational drives large bolt component retraction lock housing; In described lock housing, be provided with to dial and turn round plate, the described group of one end of turning round plate is when living torsional angle, and restriction torsional angle is rotated, and during away from torsional angle, torsional angle is rotatable, and the described group of other end of turning round plate is connected with lock core assembly, and described lock core components drive is dialled and turned round plate reciprocating motion.
Under primary condition, interior Door lock is arranged on kissing gate doorframe, and large bolt component and little bolt component stretch out lock housing, and handle assembly rotates and drives large bolt component flexible turnover lock housing and handle to automatically reset, and little bolt component keeps stretching out lock housing state.Large dead bolt is arranged on dead bolt pin and can rotates with dead bolt pin, large dead bolt and dead bolt pin are all arranged on dead bolt mount pad, big lock tongue spring is through dead bolt mount pad, lean in lock housing, integral layout is small and exquisite, simplified volume, the torsional angle being arranged in lock housing directly drives large bolt component retraction lock body, unclamps after rear handle, and large bolt component is by big lock tongue spring automatic spring, by lock core components drive, dial and turn round the rotation that plate limits torsional angle, locked hand, makes door lock locking, and integral layout is little, simple in structure, installing space is little.
In above-mentioned a kind of interior Door lock, in described lock housing, be provided with chute, in described chute, slidably connect sliding panel, one end of described sliding panel connects the second Compress Spring, and in this side direction, being bent to form stage clip installation portion, described the second Compress Spring leans on stage clip installation portion, on described sliding panel, is provided with limited block, in little bolt component retraction lock body, described limited block can stop in large bolt component retraction lock body; Described little bolt component is arranged on a side of large bolt component, and described little bolt component slides in lock housing and is resisted against on sliding panel.
In above-mentioned a kind of interior Door lock, the other end of described torsional angle is provided with spring base, the first Compress Spring is installed on described spring base, and the described first Compress Spring other end is pressed in lock housing, and described spring base one side can coordinate with sliding panel and promote sliding panel and moves.
Normally at closing time, by doorframe and large, extruding between little bolt component, large bolt component, in little bolt component indentation simultaneously lock housing, sliding panel is compressed and is resisted against on little bolt component by the second Compress Spring, handle rotates and drives torsional angle to rotate, thereby torsional angle band flexible spring seat moves sliding panel is moved, sliding panel moves compression the second Compress Spring, the first Compress Spring is also done drive lower compression at spring base simultaneously, unclamp after handle, the first Compress Spring promotes spring base and moves, torsional angle resets, the second Compress Spring promotes sliding panel and resets and be resisted against on little bolt component, when meeting theft, little bolt component Partial shrinkage enters lock body, under the elastic force effect of the second Compress Spring, sliding panel moves, when little bolt component is against living sliding panel, the limited block of sliding panel leans large bolt component simultaneously, large bolt component can not be retracted in lock housing, play anti-theft effect.
In above-mentioned a kind of interior Door lock, described sliding panel also comprises slip limiting section, pushing part and little dead bolt limiting section, described slip limiting section is set to elongated strip shaped, described pushing part is vertically set on stage clip installation portion, slide and then promote sliding panel and move in one end of described spring base on pushing part, described little dead bolt limiting section is arranged on the sliding panel other end, and described little bolt component is limited on little dead bolt limiting section.
Lock housing is rectangular tabular, sliding panel is also arranged to elongated strip shaped to coordinate lock housing, the groove that the cooperation sliding panel arranging in lock housing slides, control the movement locus of sliding panel, sliding panel one end arranges the second Compress Spring, keeps the mutual extruding of sliding panel and little bolt component, is conducive to improve antitheft respond, mutual promotion by pushing part and spring base makes sliding panel depart from the restriction to large bolt component again, guarantees the normal unlatching of door lock under normal operating condition.
In above-mentioned a kind of interior Door lock, described little dead bolt limiting section is provided with ramp, the first retainer and the second retainer, and described little bolt component is slidably in ramp or lean on the first retainer or the second retainer.
In little bolt component motion process, slide in ramp, be resisted against the first retainer when stretching out state, while meeting robber, when little bolt component compresses on a small quantity, sliding panel moves, and little bolt component is resisted against the second retainer, limits little bolt component and stretches out.
In above-mentioned a kind of interior Door lock, described little bolt component comprises little dead bolt, be arranged on the small lock tongue spring of little dead bolt one end, on described little dead bolt, be provided with wedge shape boss, described wedge shape boss leans at little dead bolt limiting section, the described little dead bolt other end is arranged to tapered end, and described little dead bolt one side is also provided with guide ledges.
Little dead bolt leans in lock housing by being arranged on the small lock tongue spring of bottom, lock housing is stretched out in one end of little dead bolt, by external force, can reduced overall enter in lock housing, the wedge-shaped design of end can effectively play the effect of guiding, make little dead bolt compress into lock body convenient, wedge shape boss is set on lock body to be leaned on the little dead bolt limiting section of sliding panel, by the slope in wedge shape and the ramp relative sliding on sliding panel, limit the position of sliding panel, simple in structure effective, the guide ledges that little dead bolt one side is also provided with, played the effect of guiding, limit the movement locus of little dead bolt.
In above-mentioned a kind of interior Door lock, on described dead bolt mount pad, be also provided with the stopper slot that is parallel to little dead bolt, described little bolt component slides in the region between lock housing and stopper slot, and described guide ledges is limited in stopper slot.
