The content of the invention

For overcome above-mentioned patented technology there are the drawbacks of, the present patent application provides a kind of swivel becket forced resetting of theftproof lock Device, only added on outer swivel becket a reset post, on the driven torus of cam correspondence position add a third flange and Reset post passage recycles original reset to push away edge and lock post, when swivel becket cannot automatically reset, is held by reversely rotating Hand simultaneously promotes reset post and lock post operation successively, that is, completes the forced resetting process of swivel becket, it is ensured that key in any case It can be inserted or pulled out.The device does not take up space, does not influence total arrangement, and the normal operating that can be automatically reset in swivel becket In the process, newly establish between component and between former component it is contactless, there is no wear phenomenons.

The present invention adopts the following technical scheme that：

A kind of swivel becket forced resetting device of theftproof lock, including lock core group and cam mechanism, the lock core group and cam machine Structure is mounted between the anti-skid plate of lockset, backboard, wherein, lock core group includes lock core, swivel becket, ring, lock post, reset drawing Spring connecting pole and pellet group, swivel becket include interior swivel becket and outer swivel becket, and lock core is fixed, and lock core periphery is followed successively by interior Swivel becket, outer swivel becket, ring and interior swivel becket inboard end fixing assembling, synchronous rotation, the one side of ring are protruded equipped with ring End, and in the gap of outer swivel becket inboard end, while the ring jag is additionally provided with limited post in vertical direction, the limit Position column is inserted into the arc slotted hole of backboard, and activity can be run wherein, and lock post, reset tension spring connecting pole are both secured to On outer swivel becket, one end connection of reset tension spring connecting pole and reset tension spring, under static, the upper side of the gap of outer swivel becket Under the action of reset tension spring with the upper side of ring jag be in close contact, cam mechanism include camshaft, rotating plate, from Dynamic lid, driven torus, collision bead and collision bead spring, rotating plate and camshaft assembling, synchronous rotation, the periphery at the inboard end of driven torus Inside pushes away edge equipped with upper flange, lower flange and reset, and upper flange, lower flange are equidirectional, and reset pushes away edge with the two direction on the contrary, multiple Position pushes away that edge is corresponding with lower flange, and groove, that is, lock post passage therebetween is run wherein for lock post, and driven torus is worn Crossing the part of the axis hole of backboard includes the circular shaft part of flat shaft portion and end, the main driving of flat shaft portion and unlocking transmission mechanism Disk fixing assembling rotates synchronously, and circular shaft part is assembled with swing rod activity, when positive and negative two direction of handle drive cam mechanism rotates, By driving main drive disk and swing rod operation to complete outdoor unlatching or the locking of lockset, it is characterized in that：On outer swivel becket also If there are one reset post, and third flange is also correspondingly provided on the left lower of lock post, driven torus, the third flange position In the right upper portion of lower flange, while it is also located at resetting and pushes away the lower right side of edge, it is equidirectional that third flange and reset push away edge, and the 3rd The lower part of flange is provided with groove, i.e. reset post passage, is run wherein for the end of reset post, when swivel becket does not reset, In driven torus since static position during reverse rotation, third flange first contacts with reset post and promotes its rotation, reset After column skids on the periphery of driven torus, reset pushes away edge and is contacted again with lock post and it is promoted to be reset to static position, with this Meanwhile the upper side of the gap of outer swivel becket promotes the upper side operation of ring jag, and interior swivel becket is made also to be reset to Static position.

Swivel becket forced resetting operation principle：During the unlocking of handle is rotated in the forward direction, the upper flange of driven torus first pushes away Dynamic ring rotates, and when ring jag on the periphery of driven torus after skidding, the lower flange of driven torus starts to connect with lock post It touches and outer swivel becket is promoted individually to rotate, lock post is also skidded on the periphery of driven torus afterwards, and outer swivel becket stops operating, Driven torus is rotated further to terminal and completes unlocking action.Wherein, lock post starts to skid and stop on the periphery of driven torus When rotation stop is moved, the reset post on outer swivel becket, which follows, turns to certain position, which makes the end of reset post enter reset In column passage.

Under normal circumstances, interior swivel becket, outer swivel becket can automatically reset under the action of reset tension spring, but in special circumstances It is lower i.e. mismachining tolerance or it is artificial it is intentional both cause to automatically reset due to when, ring jag, lock post can stop Stay in skidding position（Worst situation is that ring jag and lock post do not reset at all, but also has lock post to reset one Determine angle and situation that ring jag does not reset at all）, and driven torus after being unlocked is reversely rotated to static position process In, the periphery of driven torus also only keeps sliding contact with ring jag, lock post.When driven torus is anti-since static position To rotation（It locks operating process）When then situation it is different：Driven torus rotates backward initial stage, and reset pushes away edge and do not reach locking also Column can't reach, the corresponding machined surface on the opposite of upper flange（And flange shape）Ring jag similarly is can't reach, but Because the end of reset post at this time be in reset post passage, third flange reversion initial stage can contact and promote reset post rotation one Determine angle, reset post is skidded on the periphery of driven torus afterwards, and at the same time, lock post also follows revolution certain angle, and And the end of lock post has had been enter into lock post passage.Continue to invert with driven torus, reset pushes away edge and starts to contact and promote Lock post and outer swivel becket return back to static position, meanwhile, by the upper side of the gap of outer swivel becket to ring jag Upper side impetus, interior swivel becket is made also to be reset to static position.If without the effect of reset post, driven torus after It is continuous to be inverted in end point process, even if its rotation can not also be promoted by resetting to push away edge and contact with lock post.

In said program, lock post revolution why is made to realize the forced resetting process of swivel becket to terminal, be because It is determined for assembly relation：Lock post is turned round to terminal, then ring jag can also turn round to terminal.In turn, ring protrudes End can be turned round to terminal, but lock post may not necessarily follow revolution to terminal, because the width of the gap of outer swivel becket must be sufficiently large, It cannot ensure above-mentioned needs simultaneously.

In above-mentioned swivel becket reseting procedure, the effect of reset post is to complete reset early period of swivel becket, resets the work for pushing away edge Be complete the later stage reset.It is all components for rotating in the forward direction in driven torus and having skidded in the process, i.e. ring jag and locking Column cannot once reset, and cannot individually complete the effect of reset early period, can only be completed by other auxiliary bodies.Such as " resetting-mechanism of the fixed cross mechanical anti-theft lock of lock core " promotes lock post to be answered as early period using the bending edge of restoring lever Position recycles reset to push away edge and completes later stage reset.Certainly can also be used without the i.e. flat restoring lever of bending edge to promote The top of ring jag, as long as the lower part side of the gap of outer swivel becket and the gap of the lower part side of ring jag do not surpass A certain range is crossed, lock post can be also pushed into lock post passage, and then realize that early period resets.Certainly, flat restoring lever Certain space is still occupied, is unfavorable for master-plan and topology layout, also relates to the drive end and driven torus of restoring lever Inclined thrust surface between long term wear problem.

To the pushing course of swivel becket, essence is exactly gear drive in positive and negative two direction of driven torus of apparatus of the present invention.It dials Ring, outer swivel becket are equivalent to three each gears there are one the gear teeth and are superimposed, and two of which gear cannot mutually rotate, Monodentate above corresponds to lock post and reset post respectively.Relatively other two gears of 3rd gear can turn an angle, Monodentate above it corresponds to ring jag；Driven torus also corresponds to three gears and is superimposed, each other cannot be opposite It rotates, wherein most inboard, outermost gear corresponds to upper flange and third flange, intermediate gear respectively only there are one the gear teeth There are two the gear teeth, and it is spaced apart, lower flange is corresponded to respectively and reset pushes away edge.By designing rational size and opposite Position can realize following functions：Interior swivel becket, outer swivel becket must first be promoted to rotate synchronously, key correctly promotes outer turn again Rotating ring individually rotates, and lockset can be opened；Key is incorrect or without key, and outer swivel becket cannot continue individually to rotate, and lockset is not It can open；Cam mechanism reversely rotate when, if swivel becket fails to reset, driven torus first promotes reset post to rotate, make lock post into Enter to reset and push away in the lock post passage that edge can be got at, reset is recycled, which to push away edge, makes lock post operation to terminal, and outer swivel becket is same When promote in swivel becket also run to terminal, that is, realize interior swivel becket, outer swivel becket forced resetting, prevent key insert not into or It can not take out.

The present patent application and " resetting-mechanism of the fixed cross mechanical anti-theft lock of lock core "（Application number 201710193748.1）It compares, except restoring lever, inclined thrust surface is eliminated, also saves space, be conducive to lockset overall structure cloth Beyond office, while also eliminate the influence that forced resetting component general wear is brought.Because reset post in the present patent application with It being capable of always contactless, therefore frequent routine in the case of normal reset in swivel becket between third flange and reset post passage Operation is there is no wear problem, on the reliability of lockset without influence.In addition, the present patent application is compared with equipped with the side for pushing away edge boss Case then advantageously because pushing away periphery of the edge boss beyond driven torus（That is cylinder）, it is certain difficult to exist during the manufacturing Degree, cost can naturally also improve, and third flange and reset post passage manufacture opposite hold within the periphery of driven torus Easily, cost is also low.

The corresponding lockset of apparatus of the present invention completes locking process yet by handle is reversely rotated.In most cases, people It always locks when going out, and the process is also artificially to promote interior swivel becket, outer swivel becket forced resetting process.When unlocking again When, the two has been reset to static position, therefore there is no cannot be inserted into key phenomenon.Once lockset appearance does not reset phenomenon, will Key can not be inserted into and owner keeps outside of the door, as long as reversely rotating handle at this time can solve.

If after being inserted into key, opening lockset and opened door leaf, interior swivel becket, outer swivel becket cannot automatically reset, then not Key can be extracted out, it is necessary to which key could be extracted out to terminal, after completion swivel becket reset by reversely rotating handle.But locking bolt is located again at this time In the state of locking（Namely locked state）, can not close the door, locking bolt can be retracted if again insertable into key again, it is likely that weight Again just now the phenomenon that, indoor knob or pushing interior handle have to be reversely rotated, locking bolt is made to retract, you can closed the door.Nevertheless, This operating process is after all more cumbersome than normal condition, it is contemplated that most locksets（Qualified products）It can realize certainly It is dynamic to reset, so the simply servo-actuated operation in most cases of the reset post of the present invention, third flange, does not play a role, but is anti- Only there is " burden ", it is necessary to install insurance additional, take preventive measures completely.

The beneficial effects of the invention are as follows：Restoring lever is eliminated, saves space, lockset master-plan is easily laid out, knot Structure is compacter, and overall cost of manufacture reduces.Meanwhile forced resetting device eliminates potential there is no general wear problem Unfavorable factor, reliability are remarkably reinforced.
