Handle automatically resets and dallied principle：During handle rotating, handle rotating shaft drives drive disk to rotate, and the length of drive disk is slitted Mouthful the synchronous pin of movable plate is promoted to rotate, synchronous pin makes driven pulley, overcomes two-way multiple from pawl by promoting the bayonet socket of driven pulley The resistance of position spring is rotated simultaneously, when the rotational angle of handle it is not super it is normal unlock, in the case of required corner of locking, by two-way The thrust of back-moving spring, handle can automatically reset；When handle drives drive disk to rotate forward or backwards more than certain angle, Synchronous pin starts to contact with pushing the pushing side of plate, and is run by constantly outwards being promoted in company with movable plate, at the same time, U Shape spring is compressed, and final synchronous pin is deviate from from bayonet socket, then driven pulley is automatically reverse in the presence of two-way reset spring Revolution, now, handle, drive disk and movable plate are without hindrance and start idle running immediately, wherein, it is synchronous to sell along bayonet socket both sides Camber line or the outer ledge of linear end face and excessive ring slide, after handle rotates a circle, synchronous pin returns to pushing plate Small arc-shaped end side, and inwardly bounce back and reinsert in bayonet socket under the promotion of U-shaped spring.If continuing positive, reversely rotation Turn handle, then repeat action just now.Especially, after synchronously pin is deviate from from bayonet socket, driven pulley is fast rotation, because of bayonet socket Summit and the distance in the center of circle of rotary hole be less than arc radius on the left of driven pulley, in driven pulley turning course, bayonet socket Both sides camber line or linear end face can promote synchronous pin to continue to run laterally, and constantly be compressed U-shaped spring, therefore together Step pin can play damping action by U-shaped spring to the gyration of driven pulley, it is to avoid produce larger impact and damage some Part.

Jump ring is arranged on the outside of drive disk, the inner side of movable plate, it is therefore an objective to movable plate is not produced by the thrust of jump ring The influence of raw frictional resistance, i.e. movable plate can be moved freely；The end of origin post is passed through with pushing plate assembling behind horseshoe hole, Therefore the effect in horseshoe hole is origin post is not hindered the rotary motion of driven pulley；U-shaped spring, projection are respectively positioned on movable plate and drive Between Moving plate, therefore the effect of projection is movable plate is kept and drive disk parastate；Backplate enables movable plate art skating, It is not to produce too big gap with drive disk again.

The scope of application of product of the present invention is situation of the inside provided with overload protection arrangement of lockset or other products, no Then, when strength reverses handle, handle can dally, the necessarily lockset or the internal part of other products wrecked.It is right In lockset can also damaging property open consequence, so the requirement in national standard to antitheft Handle for lock is " when handle is broken It should ensure that lockset is not gated on after breaking down ".For example, mechanical lock of the prior art is had using rotation key unlocking mode Handle it is fixed, some handles push process and only drive dead bolt, do not drive master latch and universe rod, most of Fingerprint Lock Handle two-way reset but can not can dally.The main cause of handle of being not provided with dallying is that various locksets of the prior art are equal Using door leaf side load mode, profile feature is that the confined space inside big and thin, the i.e. finite thickness of lockset, lockset is uncomfortable Overload protection arrangement is installed in conjunction additional（Or it is untapped because of cost factor）.And the corresponding lockset of eight patents in background technology is adopted With from load mode on the inside of door leaf, profile feature is small and thick, so the handle that sets and can dally of just having ready conditions, and only exist The security performance of lockset is just clearly enhanced in terms of handle protection.

In addition, two-way automatic reset and idling device are arranged on around handle rotating shaft and lockset by technical scheme Within outer panels, if the device of function of the same race, which is installed on inside lock body, can also realize same function.For example, background technology In theftproof lock, what is assembled with handle is camshaft, and camshaft is assembled includes the driven lid of cam mechanism, if by existing skill The common two-way automatic reset device of art（Wherein include two-way reset spring）Assembled with driven lid, then camshaft and handle also can Realize two-way automatic reset and lost motion functionality.But being related to problem has three aspects, and one is must possess enough skies in requirement lock body Between relevant apparatus is set, can now use " a kind of improved baffle type mechanical anti-theft lock "（Patent No. ZL201320777538.4） Correlation technique, i.e. limiter of moment is that punching press fin plate overlaying structure, limiter pushes away spring are cylindrical spring or disk spring, this The advantage for planting structure is that axial dimension is smaller, using the teaching of the invention it is possible to provide installing space, while not influenceing total arrangement.Two be to two-way reset The elastic force of spring has particular/special requirement：Elastic force is small, and the effect that automatically resets to handle is just poor；Elastic force is big, then the bullet of limiter pushes away spring Power is accomplished by significantly increasing, and then moment of resistance when dallying is significantly increased, and causes the moment cam mechanism resilience impulsive force mistake that dallies Greatly, to associated components material, intensity requirement is high.Meanwhile, because of the probability very little that idle running occurs, limiter of moment during regular job Always " over-burden "（Because being constantly subjected to the drag effect of two-way reset spring）, durability, stability to cam mechanism Also it is unfavorable.Three be that idle resistance square is excessive, can also have a strong impact on the pellet to lockset, lock post, drive disk and push away the parts such as post Protecting effect, or even lose the existent value of lost motion functionality（When lockset can not be opened, handle is closely located to static bit Put, the elastic force of two-way reset spring now is smaller, forward and reverse rotation to terminal position when elastic force it is maximum, therefore lockset can not be opened The main reaction force by pellet, lock post of idle resistance square when opening is produced）.On the contrary, apparatus of the present invention are installed on handle The elastic force of two-way reset spring in rotating shaft can design larger, on the lost motion functionality of handle without influence, as long as people rotate handle The sensation of handle is effortless, can receive.

The beneficial effects of the invention are as follows：Automatically reset using special handle and free-wheeling mechanism, simple in construction, low cost, But the function that handle can automatically reset and can dally can be realized, lockset safety, durability and stability requirement is being met Meanwhile, the need for also meeting product convenience.
