Description
Technical field
The utility model relates to a kind of door lock, particularly a kind of door lock bolt-type free-wheeling mechanism.
Background technology
By the handle on the inside and outside lock body of turning cell (being designated hereinafter simply as outer handle and interior handle), can make the dead bolt in the dead bolt assembly of band clutch produce corresponding actions, implement the unlatching of door lock or close.The interior handle of this lock body structure is not subjected to the restriction of clutch when rotating; Outer handle rotates the unlatching door lock and then is subjected to the control of clutch, and only just can implement after legal being authorized.
The mode of the outer handle rotation of the clutch of door lock control at present is the directly rotation of the outer handle of restriction, if outer handle is kept out the incessantly destructiveness rotation of super large torsion, door lock still can be unlocked, and directly influences the safety of door lock.At this situation, a little improvement have been done by some producer, as disclosing the multi-functional mortise door lock lock body of a kind of idle running among the Chinese ZL200420083195.2, comprise lock case, tiltedly tongue assembly and tiltedly tongue opening mechanism, tiltedly the tongue opening mechanism comprises the handle turning wheel, the handle turning wheel is installed in the upper right side of lock case, tiltedly the tongue assembly is installed in the lock case middle part, it also comprises the handle free-wheeling mechanism, this handle free-wheeling mechanism comprises the idle running ring, the insurance thumb wheel, lock slide, the slide plate leaf spring, startup board, latch and latch spring, the idle running ring set is in handle turning wheel the inside, insert the handle parts in the hole in the middle of the idle running ring, through hole the inside on the handle turning wheel is equipped with latch and latch spring, the tail end of latch is inserted in the hole slot that dallies on encircling, the insurance thumb wheel is installed in the lower right of lock case, the driving lever top that the insurance thumb wheel stretches out extend between two projections of lock slide bottom, the bottom of lock slide cooperates with the slide plate leaf spring, the lock slide top withstands on the outside, middle part of startup board, on startup board one end is installed in the hole of lock case, other end freedom, the inboard of startup board is pressed in the top of latch.The lock body of this structure is under non-door opening state, outer handle is in the sky that does not stress and revolves state, can prevent the outer handle of outside violence damage effectively, cause the lockset internal construction to lose efficacy, strengthened the lockset theftproof performance, but the lock body component of this structure are various, cost of manufacture is high, the operation underaction.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of compact conformation, good rigidly, volume is little, cost of manufacture is low, flexible operation, door lock bolt-type free-wheeling mechanism that security performance is high, to overcome weak point of the prior art.
The technical scheme in the invention for solving the above technical problem is: a kind of door lock bolt-type free-wheeling mechanism, comprise outer shift fork that joins with outer handle and the interior shift fork that joins with interior handle, its architectural feature is that outer shift fork and interior shift fork are inserted into respectively on the idle running pull-fork assembly, the idle running pull-fork assembly comprises the shift fork central layer that is arranged between the forward and backward shift fork clamping plate, and the latch that is arranged on band spring on the shift fork central layer; Latch one end and outer shift fork join, its other end stretch out the shift fork central layer, and the dead bolt assembly in clutch join.
Be provided with the jack of perforation in above-mentioned forward and backward shift fork clamping plate and the shift fork central layer, outer shift fork and interior fork are inserted in the jack; The corresponding latch of outer shift fork is provided with open slot or spliced eye; Back shift fork clamping plate jack periphery is provided with fan-shaped opening, and corresponding being provided with rotated and used protruding key on the interior shift fork.
Above-mentioned outer shift fork is provided with the butt joint round platform, and this butt joint frustum cone side is provided with open slot or the spliced eye that cooperates with the latch end; Interior shift fork is provided with the butt joint boss, and this butt joint boss side surfaces is provided with to rotate uses protruding key.
Above-mentioned preceding fork clamping plate jack periphery is provided with fan-shaped opening.
Above-mentioned shift fork central layer is provided with radial direction through hole, is provided with latch in this radial direction through hole, is socketed with spring on the latch, and spring one end is resisted against on the limited step in the through hole, and its other end is arranged on the latch; Latch is outside equipped with catch, and catch is provided with the hole or the open slot of allowing that the latch end frees in and out.
Above-mentioned catch bag is connected on shift fork central layer side, and the corresponding spring other end of latch is provided with limited step or back-up ring, and limited step or back-up ring are crimped on the catch.
The utility model is in off position the time, and the square latch is overhanging under spring action, and outer shift fork rotates arbitrarily at the Kong Zhongke of idle running pull-fork assembly, is idling conditions.When needs during from outdoor opening the door, the square latch inserts under the promotion of clutch in the open slot with the outer shift fork of outer handle interlock, and outer shift fork joins together with the idle running pull-fork assembly, rotates outer handle drive and sells tonguing, enforcement is opened the door, and opens the door by force thereby avoided violence to reverse outer handle; Because back shift fork clamping plate jack periphery is provided with fan-shaped opening, so when outer shift fork drove the rotation of idle running pull-fork assembly, it is motionless that interior shift fork keeps, outer shift fork and the rotation of interior shift fork when opening the door are not disturbed mutually.When needs during from indoor opening the door, handle in rotating, shift fork rotated in interior handle drove, and was arranged on protruding key in the fan-shaped opening and drove the idle running pull-fork assembly and drive dead bolt and open.
The action of opening the door of the inside and outside handle in the utility model is not disturbed mutually, and the torsional moment when keeping opening the door is identical, and outer handle is motionless when having avoided interior handle to rotate, and outer handle when rotating in the torque difference of handle interlock generation.Behind the open slot outside the latch of square structure inserts on the shift fork, the pull-fork assembly that will dally joins the great efforts of its transmitting torque, durability height together with outer shift fork; And the rotation of inside and outside fork is not disturbed mutually, makes the torque of inside and outside handle when opening the door of door lock identical.
The utility model compact conformation, good rigidly, volume are little, can directly change with the corresponding component in such non-idling dead bolt assembly.
Forward and backward shift fork clamping plate in the utility model are set to the same structure, this structure guaranteed that door lock can be random about install, and the branch about not having greatly reduces cost.
The utility model compact conformation, good rigidly, volume is little, cost of manufacture is low, flexible operation, security performance height.
