Technical field:
The utility model relates to a kind of door lock, relates in particular to a kind of door lock that can carry out open and close by the handle that revolving door is locked, and this door lock is used to open and close door inboard or the outer side of door that is installed in various public arenas.
Background technology:
At present, the door lock that is used for the open and close door in public places such as family or offices is to carry out open and close by the handle that is rotatably provided in a medial and lateral.The handle that is used for these door locks mainly adopts is convenient to knop or the bar shaped handle that hand is grabbed.The suitable height of these existing door locks on door connects the sleeve pipe that tubulose is set, in being provided with around it, being provided with various door locks and untiing the body of using parts, fixing medial and lateral flange between the two ends of above-mentioned sleeve pipe and door, and the handle of switchgear is set on the end of sleeve outstanding between the flange of above-mentioned medial and lateral, and in this handle, the locker that comprises slide block is set.Also have, the latch of being handled by medial and lateral handle and locker is set in above-mentioned door, the dead bolt that links to each other with above-mentioned latch is set on doorframe, thereby by the rotary manipulation of above-mentioned handle, the dead bolt that will link to each other with latch injects in the lock frame that is fixed on the doorframe or deviates to carry out open and close the lock frame on being fixed on doorframe.Yet, because too much causing cost, parts rise and problems such as fault takes place frequently, even lock above-mentioned door, also can open the door with blade, awl, iron wire etc., therefore cause problems such as user's uneasiness and snap close effect be not good enough; And, thereby continue to take place friction and wear reduction of service life between the same parts when carrying out open and close.Obviously, the door lock that is installed on public place in the prior art is failed to solve component too much to reach the snap close effect good enough etc.
The utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of door lock is provided, and the utility model has reduced employed component and strengthened the snap close ability of door lock.
The technical scheme that the utility model solves prior art is: a kind of door lock, on the door body of an indoor side and an outdoor side, indoor lock housing and the outside lock housing that has through hole is installed respectively, pass indoor respectively, the through hole of outside lock housing is provided with through hole and cooperatively interacts and rotating indoor handle and outdoor handle, indoor, the end that outer handle passes through hole is socketed with indoor axle sleeve and outside axle sleeve respectively, indoor, outside axle sleeve is respectively with indoor, be provided with the jump ring that resets between the lock housing of the outside, indoor, outboard shafts puts and is with rotating shaft of telescopic indoor and outside rotating shaft respectively, indoor towards handle, the end of outside rotating shaft all connects the spring that places in the handle, and is indoor, the external part of outside rotating shaft mutually towards and pass the door lock mechanism that has the through hole lock housing; Be connected with dead bolt on the lock housing of door lock mechanism, dead bolt is connected with the lock frame that places in the lock housing, the lock frame is connected with the back-moving spring that places in the lock housing, is provided with the fan type indoor cam that cooperates with indoor and outdoor side rotating shaft axle respectively and the outside cam of fan type in the wherein said lock housing; Described lock frame has opening, the opening that the lock frame compresses when also having with indoor and outdoor side cam rotation mutually.Thereby drive the rotation that indoor and outdoor side rotating shaft rotating shaft realizes indoor cam and outside cam respectively by turning cell Internal handle and outdoor handle, when indoor cam or outside cam rotation, make with locking dead bolt that frame is connected and follow and lock frame and be retracted in the lock housing thereby its cam is depressed the opening of lock frame, reach the effect of opening the door.In addition, dead bolt is in the rotations that lock housing can 360 degree when outer, makes dead bolt can adapt to the different mounting means of doorframe iron card that cooperates with it.
The utility model further is designed to: also be provided with two through hole on the lock housing and pass the movably body of rod of two through hole, place one section body of rod respective chamber/chambers medial and lateral cam in the lock housing to have step-like high and low boss, the outside cam has the deep notch that cooperates with high boss, the indoor cam has and hangs down the shallow concave recess that boss cooperates, and the cross section of shallow concave recess is trapezoidal shape; Have aperture on the lock housing of described indoor, a spring catch assembly passes aperture and contacts with body of rod end, the spring catch assembly by the shank of two ends band cap and the bullet guide that passes aperture by spring form.Leave certain space between the top of indoor cam and high boss, the indoor cam can be rotated.During initial position, the top of high boss is in the relative position of scrobicula platform that cooperates with boss, and indoor and outdoor side cam all can rotate; When the spring catch components drive body of rod makes high boss fall into deep notch and low boss falls into shallow concave recess, at this moment, the outside cam can not rotate outdoor handle by high boss is stuck, thereby realizes locking; When the turning cell Internal handle, the indoor cam rotation makes low boss slide along the outward flange of shallow concave recess, thereby makes the whole body of rod be returned to initial position, and releasing is locked.Can also have towards the perforate of body of rod the other end on the lock housing of outside among the design, the perforate of offering can make door lock be in when locking state, utilizes iron wire or toothpick etc. to pass perforate the body of rod is pushed up back original state, can remove equally and lock.Or the end that contacts with the body of rod of the shank of spring catch assembly also can be to be provided with screw thread and not to be with cap, the body of rod one end that contacts with shank is provided with the screw with the screw thread coupling, cooperate with screw by screw thread, the dead spring pin assemblies forms and locks, the pulling shank is removed and is locked, and such design is locked with regard to not needing the turning cell Internal handle to remove, and utilizes this widget of shank dexterously, it is more convenient, more laborsaving that door lock is used.
Rotating shaft of aforesaid indoor and outside rotating shaft are with clip shutter respectively, and clip shutter is inserted in the thickness of the length of indoor and outdoor side rotating shaft no longer than indoor and outdoor side cam.It is long that the effect of clip shutter can make indoor and outdoor side rotating shaft can not stretch into indoor and outdoor side cam, thereby realize indoor and outdoor side rotating shaft medial and lateral, independent control room cam rotation respectively, and certainly, more optimized design is; The length that clip shutter is inserted in indoor and outdoor side rotating shaft respectively with the consistency of thickness of indoor and outdoor side cam.
The utility model novelty simple in structure, lower, the employed component of cost are less, its drive disk assembly is simple, compact, flexibly, reliable; Drive disk assembly power consumption is little, and the operator is easy to use.This door lock has reliable lock function, and the action of the handle of door lock and dead bolt synchronously, accurately.And this door latch structure simplified the technology of original installation and removal, produces easily and promotes, and is widely used on the door body in various open places.
