A kind of mortise lock handle Axile connection structure with escaping function of the present invention is illustrated referring to the drawings.

The present invention relates to a kind of, and the mortise lock handle Axile connection structure with escaping function substantially divides as shown in Figures 1 to 4 For shell（10）, keeper（20）, sub- pin（30）, lock tongue（40）, by keeper operating parts（50）And driven gear（60）And controller （70）With locked wheel（80）With locked limited block（90）The keeper operating unit of composition（DU）, by bolt limited block（100）With insert Sell brake block（110）With bolt cam（120）The lock tongue locking unit of composition（LU）, by first axle（130）With the second axis（140） And chaining part（150）With bolt cam（120）With locked wheel（80）The escape link unit of composition（PU）, motor（M）, described to insert Sell cam（120）With locked wheel（80）Composition realizes indoor handle（It is not shown）The cam member of escaping function（C）.

In order to make it easy to understand, illustrating core of the invention by keeper first axle first（130）, the second axis（140）, chaining part （150）The escape link unit of composition（PU）, then briefly describe remaining mortise lock detailed construction and operation principle.

First, core of the invention escape link unit（PU）Including：It is inserted into the indoor first axle on mortise lock two sides respectively （130）With outdoor second axis（140）, by the first, second bolt cam（120A）（120B）With locked wheel（80）Composition Cam（C）It is inserted into first axle（130）Second axis（140）And it is connected to the cam（C）On, make indoor first mortise lock cam （120A）With locked wheel（80）With indoor first axle（130）The chaining part rotated together（150）.

First, the first axle（130）And second axis（140）It is inserted into the indoor another with outdoor on one side of mortise lock respectively Face, and the second axis（140）And first axle（130）Upper junction chamber outdoor handle and indoor handle, lateral surface by square structure fuselage With the connector for being connected to each inboard end（131）（141）Composition, this point is identical, and the second axis (140) is outer Diameter is bigger than the outer diameter of first axle (130), moreover, the first connector of first axle (130)（131）With the second axis（140）Second Connector（141）It is the combination of inner and outside for mutual corresponding circular configuration, and the first axle（130）And second axis（140）In phase On coaxial line in the state of arrangement connection, mutually dally, these and above-mentioned difference.Here, the first axle（130）And the Two axis（140）Each connector be circular configuration, be the combination of inner and outside, refer to, when in order to be rotated there are one axis, another axis keep Stationary state sets the lateral surface of first axle and the second shaft coupling piece (131), (141) to mutual corresponding circular configuration.

At this point, there is no limit still, since the outer diameter of the second axis (140) is big for the interconnection structure of first axle and the second axis In first axle (130), in order to make first axle（130）And second axis（140）Assembling it is more preferably convenient, first connector (131) it is the spherical outer connector protruded, and second connector（141）It is then opposite to should be the vaulted outer connector, be The interconnecting piece of the interconnecting piece of spherical concave, the outer connector of the first axle (130) and second axis (140) is interference Cooperation, realizes the first axle（130）And second axis（140）Between independent rotation.

In addition, the connecting hole (81) with the second axis (140) same outer diameter is respectively set on the cam member (C) (121), it is inserted into and connects the first axle (130) or second axis (140), including：When rotation, lock tongue (40) is unlocked A pair of of bolt cam (120A) (120B), and be arranged on the pair of bolt cam (120A) (120B), when rotation unlocks The locked wheel (80) of keeper (20).

That is, above-mentioned locked wheel (80) includes rectangular connecting hole with the first, second bolt cam (120A) (120B) (81) (121) correspond to first axle（130）And second axis（140）.

In addition, there is the connecting hole with the first axle (130) same outer diameter and same diameter on the chaining part (150) （151）, it is inserted into the first axle (130), and be inserted into the state of the cam member (C) connecting hole (81) (121), by described Second axis (140) one of makes in these bolt cams (120) to revolve together with the locked wheel (80) to indoor moving Turn.

Specifically, the chaining part (150) is and first axle（130）And second axis（140）It is corresponding rectangular cabinet type to match Part, outer diameter is identical as the second axis (140), and the internal diameter of connecting hole (151) is identical as the first axle (130).

In the state of being inserted into chaining part (150) on the connecting hole (81) (121) of cam member (C), the connecting hole (151) Interior insertion first axle (130), and on the outdoor face of shell (10), it is inserted into the connecting hole (121) of the second bolt cam (120B) Second axis (140), meanwhile, chaining part (150) is moved to first axle (130) direction, keeps locked wheel (80) and the first bolt convex Wheel (120A) is rotated together with first axle (130).

Therefore, interior the first bolt cam (120A) for being linked by the chaining part (150) and locked wheel (80) with The first axle (130) is linked, without outdoor the second bolt cam linked with the chaining part (150) (120B) links with second axis (140).

That is, using a pair of of bolt cam (120A) (120B) and locked wheel (80), and the existing mortise lock with escaping function Including when assembling mortise lock and installation, indoor first axle (130) is inserted into indoor first bolt cam (120A) and locked wheel (80) On, and outdoor second axis (140) can be only inserted on outdoor bolt cam (120), could normally realize escaping for indoor handle in this way Raw function, will such as be properly inserted these axis as a result, need especially careful, so that the assembling of mortise lock and installation is become cumbersome, pass through this The chaining part (150) of invention, can to solve the above problem, and so that mortise lock is assembled and is installed becomes simple.

Specifically, the cam member (C) include along axis length direction the connecting hole (81) (121) medial surface Upper recessed guide part (CG), the chaining part (150), which is included on the guide part (CG), to be slidably connected, and outer side into The guide pad (152) of row protrusion.

The guide part (CG) includes locking wheel (80) and along both sides the first, second bolt cam (120A) (120B) The medial surface of connecting hole (81) (121) carries out recessed guide groove (81a) (121a), this chaining part in the length direction of axis (150) sliding connection structure so that when assembling the second axis (140), the movement of chaining part (150) position becomes to be more prone to.

There is the chaining part (150) to be carried out along the guide part (CG) on two ends of the guide part (CG) as a result, When mobile, the anti-detachment step (121b) of the guide pad (152) is blocked.

That is, two ends of the guide groove (81) of intermediate locked wheel (80) are connected to the two sides of locked wheel (80), and both sides Guide groove (121a) inside end of first, second bolt cam (120A) (120B) is connected to bolt cam (120A) (120B) Medial surface, while being connected to the guide groove (81) of locked wheel (80), and outside end is connected to the medial surface of connecting hole (121) There is anti-detachment step (121b) in designated position in the lateral surface end of each bolt cam (120).

This anti-detachment step (121b) can prevent disengaging of the chaining part (150) on cam member (C), especially, lead to When crossing the second axis (140) chaining part (150) and being moved to indoor direction, chaining part (150) is set to be parked in accurate position, to prevent Second axis (140) is inserted into excessive phenomenon.

Therefore, have on the bolt cam (120) and carry out recessed swivelling chute (127) in medial surface, institute can be inserted The lateral surface for stating locked wheel (80) has on the medial surface of the swivelling chute (127) or the lateral surface of the locked wheel (80) Brake pad (128) makes the bolt cam (120) be maintained a certain distance with the locked wheel (80).

That is, have locked wheel (80) between the first, the second bolt cam (120A) (120B) of the invention, it is mutual in these cams It in the state of being adjacent to, can complete individually to act, by the brake pad (128), reduce the rubbing surface between these cams Product, when preventing locked wheel (80) rotation, the phenomenon that rotation of outdoor second bolt cam (120B) is interfered.

Especially, according to the mounting structure of door, the installation direction of mortise lock is also different（Mortise lock is mounted on the left side of door or inserts Lock is mounted on the right side of door）, therefore, installation personnel is considered as the direction of indoor and outdoor, and first axle (130) is inserted into shell (10) One side, and the second axis (140) is inserted into the another side of shell (10) or first axle (130) is inserted into shell (10) Another side, and the second axis (140) is inserted into the one side of shell (10), at this point, the first, second axis (130) (140) are filled Become to be even more important in accurate position.

But just as it is above-mentioned it is described as, existing mortise lock due to the defect in the chaining part (150) structure, if When the connection of second axis (140) is long, escaping function can be also realized in outdoor, in this way to generating hidden danger safely, when installation also needs Want especially careful.

On the contrary, regardless of the installation direction of mortise lock, the present invention by the first, the second axis (130) (140) according to indoor and Outdoor direction, simply inserting connection just can realize escaping function.

That is, in Fig. 4, when first bolt cam (120A) arranged direction is indoor, the chaining part (150) is mounted in convex In the state of gear member (C) connecting hole (81) (121), according to indoor outside direction, it is inserted into the first, the second axis (130) (140), and will When second axis (140) shifts bottom onto to interior, due to there is pressure on the second axis (140), chaining part (150) is to the first bolt cam The direction (120A) is moved, and is stuck on the anti-detachment step (121b) of the first bolt cam (120A), in this way, first axle (130) It travels naturally through chaining part (150) and the first bolt cam (120A) and locked wheel (80) link linkage, and the second axis (140) it only carries out linking linkage with the second bolt cam (120B),

On the contrary, in Fig. 4, when second bolt cam (120B) arranged direction is indoor, according to above-mentioned identical mode, it is inserted into the One, when the second axis (130) (140), due to there is pressure on the second axis (140), chaining part (150) is to the second bolt cam (120B) Direction is moved, and is stuck on the anti-detachment step (121b) of the first bolt cam (120B), in this way, first axle (130) is naturally It carries out linking linkage by chaining part (150) and the second bolt cam (120B) and locked wheel (80), and the second axis (140) is only Link linkage with the first bolt cam (120A), thus it is automatic realize linking for axis and each cam, such mortise lock is installed Operation becomes simple and quick.

For example, when passing through indoor handle, first axle（130）Unidirectionally（Clockwise）When being rotated, pass through locked wheel （80）, lock limited block（90）To another direction（Counterclockwise）It is rotated, as a result, keeper operating parts（50）Unidirectionally （Clockwise）While rotation, by keeper（20）It pushes backward, realizes keeper（20）Unlock；By indoor handle, One axis（130）To another direction（Counterclockwise）When being rotated, and according to identical principle realization keeper（20）'s Unlock.

By room inner handle escaping function, after the unlock for realizing keeper (20), induction pieces (72) microswitch induction solution Except part, if delay time is already expired or incudes at closing time, the motor (M) again pushes ahead keeper (20), meanwhile, Keeper (20) pops up, and realizes the locking of door.

At this point, the locked limited block（90）Solve slip bolt（20）Afterwards, pass through the third elastomer（93）It automatically returns to Original position, meanwhile, locked wheel (80) and first axle (130) can also automatically return to original position.

In addition, the bolt limited block (100) drives bolt brake block (110), passes through the bolt by being moved forward and backward Brake block (110) selectively allows for or prevents the lock tongue (40) to snap into, and bolt cam (120) is by operating handle, Control what the bolt limited block (100) was moved forward and backward.

The general operation principle of this mortise lock is as follows:

First, keeper (20) pops up and under door locking state, when opening door by the escaping function of indoor handle, passes through the rotation of axis Turn, locked wheel (80) and bolt cam (120) are rotated unilateral side to the left and right, and at this time, by locked wheel (80), keeper is by bullet Into realization unlock.

Meanwhile bolt cam（120）Pressurizing block（122）（123）One of in the middle by bolt limited block（100）To When preceding promotion, bolt brake block（110）It is swung forwards, meanwhile, closing piece（111）It is detached from the second housing（42）Contact （42a）, realize lock tongue（40）Unlock, when opening the door in this state, lock tongue（40）Contact door latch（S）And after springing into, disappear Except sub- lock（20）And door latch（S）On external force, in this way, all be ejected.

Door is opened, and when decontroling handle, locks wheel（80）With bolt cam（120）Original position is will be returned to, at this point, bolt cam （120）On pressure can eliminate, but under door opening state, in sub- lock（30）Therefore upper no external force passes through first coil bullet Spring, the first head（31）It will be ejected completely, pass through pressing means（35）Bolt limited block（100）It continues to move along, locks in this way Tongue（40）Unlocked state is kept, when at closing time, lock tongue may be implemented（40）Snap into pop-up,

After shutdown, pass through motor（M）The driven gear of drive（60）Make keeper operating parts（60）It is restored to original position, meanwhile, door Bolt（20）Locking is realized in pop-up.

In addition, keeper pops up（20）, under door locking state, the defeated of button or outdoor password is opened by indoor main part After entering etc. to be unlocked, pass through the motor（M）Rotate gear（G1）And driving gear（G2）, and drive driven gear（60）, According to driven gear（60）Rotation, the keeper operating parts（50）Also it will rotate together, and at this point, keeper is sprung into, realize unlock, And use the bolt cam（20）It opens behind the door, keeper（20）Again the process for popping up and locking is same as described above.

Operation principle of the present invention can pass through chaining part on the mortise lock with escaping function（150）It is easy real Existing escaping function, the assembling and installment work of mortise lock are simple and quick.

Especially, in the operation principle, keeper（20）And lock tongue（40）Locking and unlocking structure it is without being limited thereto, this Simply facilitate a kind of example of explanation, a pair of of bolt cam（120）With locked wheel（80）Upper individually the first, second axis of link （130）（140）And realize all kinds mortise lock of escaping function, it is suitable for the present invention.

More than, with reference to the drawing of the present invention, the mortise lock handle Axile connection structure with escaping function is illustrated, but General technical staff of the technical field of the invention can carry out various modifications in the technological thought of the present invention and range And change, these deformations and change all belong to the scope of protection of the present invention.
