In addition, the sub- lock (30) includes: pressing means (35), it is bent downwardly and connects in the rear end of the first housing (32) It connects, when forward movement, when pressurizeing, and moving backward to the bolt limited block (100), releases the bolt limited block (100) pressure.

This seed lock (30) in addition to after locking a door son lock (30) become semi-convex and do well and become by the contact of door latch (S) For complete bullet into state, the pressing means (35) push ahead the ejector block (101) of bolt limited block (100), and bolt is limited Position block (100) moves forward.

The front of the pressing means (35) connects inserting block (35a), when it is moved forward, inserting block (35a) insertion In the insertion groove (101a) of bolt limited block (100).

The sub- lock (30) includes: the contact (36) that side protrusion connects to the left and right on the first housing (32), When first head (31) is ejected completely, the contact (36) contacts mortise lock induction pieces (70) and is incuded.It is this Microswitch can be used in induction pieces (70), incudes whether the contact (36) is physical contact.

In addition, the sub- lock (30) passes through the contact of door latch (S), turning for the first head (31) left and right directions is realized It changes, and bullet is into pop-up.

For this purpose, first head (31) is made of symmetrical the first, second inclined-plane (31A) (31B), they are stretched out The outside of shell (10), front and back sides tilt down forward, when door opening and closing, according to the direction of contact door latch (S), and the One head (31) is swung centered on first axle pin (33), meanwhile, switch the first, second inclined-plane (31A) (31B) Direction, the first head (31) carry out bullet into pop-up.

Symbol 31a on drawing is the first supporting block of semicircle (31a) stretched out in first axle pin (33) rear surrounding, And first supporting block (31a) contacting side wall end (11) when the first head (31) swing, play the role of fulcrum, and When first head is popped up while contacting side wall end (11), the first head returns to the neutral position before swinging.

Next, the lock tongue (40) can stretch to shell (10) is external, including, elasticity is carried out to ejection direction The second head (41) of support.

Specifically, the lock tongue (40) includes that can carry out the second flexible head to the third telescopic hole (11c) (41), and it is connected to second head (41), to ejection direction resilient support and in the internal back-and-forth motion of shell (10) The second housing (42) and hinge connect second head (41) and the second housing (42), make second head (41) the second hinge pin (43) to swing has contact bolt brake block at the rear of the second housing (42) (110) support slot (42a) of closing piece (111).

This lock tongue (40) is according to the curved spring (44) and/or person's bolt brake block being fixedly connected on shell (10) (110) reset swings pressure, identical as sub- lock (30) by ejection direction elastic pressurized, passes through door latch (S) Contact completes the left and right directions switching of second head (41), carries out bullet into pop-up.

The shape on the second head (41) of lock tongue (40) can be with the first head (31) phase of the sub- lock (30) as a result, Together, still, shaking in order to prevent at closing time, in the state of being supported, the second head (41) can be in the second housing (42) front is arranged up and down, and centered on the second hinge pin (43), the first inclined-plane (41Aa) for being oppositely arranged A pair seperated (41A) (41B) that (41Ba) is formed by cross form, when door opening and closing, its in fission (41A) (41B) In one swung, meanwhile, the second head (41) rear carries out bullet into pop-up forward.

That is, each back side of a pair seperated (41A) (41B) of composition the second head (41) is supported by the second housing (42), and In the state of shared second hinge pin (43), each lateral surface (41Ab) (41Bb) is arranged in parallel in the lateral direction, meanwhile, each inside (41Aa) (41Ba) is intersected to form with X-shaped shape in face, therefore, as long as lock tongue (40) not bullet into, it is each fission (41) (41B) no It can swing, can not thus open the door, only lock tongue (40) is by bullet into one can just put in the base in seperated (41A) (41B) It is dynamic, meanwhile, by by bullet into pressure, the second head (41) could bullet into that is, lock tongue (40) can just move backward.

For example, when opening the door, if the lateral surface (41Ab) of first seperated (41A) contacts door latch (S), the second housing (42) It will elapse backward, meanwhile, first seperated (41A) (41B) seperated with second is swung with identical angle, makes first, the The lateral surface (41Ab) and medial surface (41Ba) of diad (41A) (41B) contact door latch (S), thus, the second head (41) Squeeze into the inside of shell (10), in this way, lock tongue (40) by bullet into inside, when the contact of door latch (S) is released from (that is, external force solution Except) when, by the pressurization of curved spring (44) and bolt brake block (110), lock tongue (40) is ejected automatically, meanwhile, swing First seperated (41A) sets back.

Therefore, each seperated (41A) (41B) of second head (41) includes: to have and first supporting block (31a) The second supporting block (41a) of identical function；When the second head (41) bullet into when, to contact the shell (10) sidewall end (11) The second supporting block end (41a) be fulcrum swing it is seperated (41A) (41B)；When the second head (41) pop-up, point of swing The second supporting block end (41a) of body (41A) (41B) contacts the sidewall end (11) of the shell (10), meanwhile, it is corresponding seperated (41A) (41B) restores the original position to before swinging.

But the first head (31) of sub- lock (30) returns to neutral position by the first supporting block (31a) when being ejected It sets, it is different, when the second head (41) of lock tongue (40) is ejected, pass through the second supporting block (41a), each fission (41A) (41B) will be returned to the position of intersection, and this point is had any different with above-mentioned sub- lock (30).

At this point, the first supporting block (31a) is subject to the neutral position of the first head (31), both ends contacting side wall end (11), On the contrary, the second supporting block (41a) is subject to the swing position that each seperated (41A) (41B) intersects, both ends contacting side wall end (11)。

Therefore, in order to which the swing of each seperated (41A) (41B) resets and steadily supports, the both ends of the second supporting block (41a) There is identical as the plane aspect of sidewall end (11) and lateral bend connection outward supporting table (41b) (not regarding out in figure), and it is this Supporting table (41b) is equally applicable on first supporting block (31a).

Then, to the keeper (20) carry out bullet into the keeper operating unit (DU) of pop-up include: keeper operating parts (50), It directly locks and solves slip bolt (20)；Driven gear (60) drives the keeper operating parts by the rotary force of motor (M) (50)；Controller (70) is controlled when keeper (20) work by motor (M), and the driven gear (60) are restored to original Position；Locked wheel (80) and locked limited block (90) complete keeper (20) bullet into pop-up, realize escaping function when rotating handles.

Firstly, the keeper operating parts (50) is pressed according to the rotation of family inner handle or indoor opening with escaping function Button or outdoor Password Input etc., in addition (M) of motor starts, start to be rotated, meanwhile, backward by the keeper (20) It pushes away, realizes the bullet of keeper (20) into unlocking.

At this point, locked wheel (80) and locked limited block (90) that keeper operating parts (50) of the invention is rotated drive, Realize family inner handle escaping function.

Unaccounted drawing symbol 51a is a kind of key insertion hole, and user is inserted into key shape on keeper operating parts (50) Manual key (not shown), keeper operating parts (50) can directly be manually operated.

This key insertion hole (51a), can be with when forgetting Password or the reasons motors (M) such as battery discharge can not work By in manual key insertion keeper operating parts (50) of key shape, user directly can be manually rotated keeper operating parts (50).

The driven gear (60), which is connected on motor (M), to be rotated, on drawing, driven gear (60) and motor gear There is the driving gear (G2) for being engaged and rotating by the fixing axle (13) of the shell (10) between wheel (G1).

When this driven gear (60) is rotated forward and inverted by motor (M), make the keeper operating parts (50) to phase Same direction is rotated, and realizes the locking and unlock of keeper (20).

The controller (70) allows the driven gear (60) to carry out just to one direction by the operating of the motor (M) Turn, meanwhile, the keeper operating parts (50) is run, inverts the driven gear (60) to other directions, such keeper (20) it just pops up, i.e. locking keeper (20).

There are many control modes, wherein the controller (70) once rotates in motor (M), and when mistake certain time, by force Make to property processed motor (M) walk around for 2 times to opposite direction, driven gear (60) is restored to home position.

For this purpose, the controller (70) may include: the sensor tooth for being engaged rotation with the driven gear (60) It takes turns (71), and the microswitch (73) by incuding sensor gear (71) rotation, and transmission is anti-to on the motor (M) The induction pieces (72) of rotaring signal.

Below to family inner handle escaping function the locked wheel (80) and locked limited block (90) be illustrated.

Firstly, the locked wheel (80) is linked in connection family inner handle first axle (130), links and revolve with indoor handle Turn, including centered on rotary shaft, the first pushing block (82) and the second pushing block (83) that are protruded to two sides.

In addition, the locked limited block (90) is pivoted about with the fixing axle (15) of the shell (10), and The side of the locked wheel (80) is rotated, including centered on fixing axle (15), side protruded and contacted described the The subsequent crushing block (91) of one pushing block (82), the second pushing block (83), and protruded to the other side, it is carried out with keeper (20) The drive block (92) of connection.

At this point, the crushing block (91) contacts and connects first pushing block (82), behind the second pushing block (83), and The drive block (92) contacts and connects the operating parts (52) of the keeper operating parts (50) below.

Therefore, by indoor handle, first axle (130) is two-way when being rotated, and locked wheel (80) linkage is simultaneously two-way It is rotated, and any one in first, second pushing block (82) (83) pushes the crushing block (91), is made described Locked limited block (90) are rotated, meanwhile, the drive block (92) also swings together, realize the keeper (20) and bullet into.

Specifically, when first axle (130) is rotated clockwise, first pushing block (82) pushes described squeeze Briquetting (91), meanwhile, locked limited block (90) are rotated counterclockwise, at this point, the drive block (92) swung pushes institute Operating parts (52) are stated, rotate keeper operating parts (50) clockwise, meanwhile, the operating parts (52) of swing makes keeper (20) it moves backward, meanwhile, keeper (20) springs into the inside of shell (10).

On the contrary, second pushing block (83) pushes the extruding when first axle (130) is rotated counterclockwise Block (91), meanwhile, locked limited block (90) are rotated counterclockwise, make keeper operating parts (50) clockwise into Row rotation, at this point, keeper (20) moves backward, and springs into the inside of shell (10) by operating parts (52).

By family 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) pop-up, realizes the locking of door.

At this point, being automatically returned to after locked limited block (90) solution slip bolt (20) by the third elastomer (93) Original position, meanwhile, locked wheel (80) and first axle (130) can also return to original position.

Illustrate core of the invention part lock tongue lock cell (LU) below.

The lock tongue lock cell (LU) includes: the bolt limited block that bolt brake block (110) are driven by being moved forward and backward (100), and selectively allow for or prevent the lock tongue (40) bullet into bolt brake block (110), and pass through operation handlebar Hand controls the bolt cam (120) that the bolt limited block (100) is moved forward and backward.

Firstly, the bolt limited block (100) is moved forward and backward between the sub- lock (30) and the lock tongue (40), together When, it is elastically supported moving back direction.

Specifically, the bolt limited block (100) includes: to be inserted into the ejector block (101) of the pressing means (35) in rear end, With the pressurizing block for rearward protruding/contacting the bolt cam (120) respectively in the left and right sides of the ejector block (101) (122) (123), stops (124), groove (125) (126) supporting element (102), and with the bolt brake block (110) carry out Hinged chaining part (103), and bolt limited block (100) is being moved backward into the second elasticity that direction flexibly supports Body.

There is i.e. the second coil spring of the second elastomer (104) on drawing, it is arranged inserts in bolt limited block (100) front end Enter between part (105) and the second support (17b), passes through the elastic force of second coil spring (104), bolt limited block (100) same with the first elastomer phase by pressure backward, the second elastomer does not have the type of elastomer or link structure etc. It is restricted.

At this point, the chaining part (103) is the slot or cyclic structure for having certain length up and down, make itself and the bolt system The swing component (112) of motion block (110) slides link, when bolt limited block (100) are moved forward and backward, sends out on chaining part (103) The height displacement of raw swing component (112).

Therefore, the aeroelastic requirements for flexibly supporting the first coil spring (34) on sub- (30) first head (31) of lock are greater than Flexibly support the second coil spring (104) of the bolt limited block (100).

Therefore, as long as passing through the bullet of first coil spring (34) without direct external force on bolt limited block (100) Property, sub- lock (30) forward movement, meanwhile, pressing means (35) push ahead bolt limited block (100), the second coil spring (104) under confined state, bolt limited block (100) is moved forward.

In addition, the bolt brake block (110) includes closing piece (111), the closing piece (111) is in the bolt limited block (100) it when being moved forward and backward, can swing up and down, when the closing piece (111) one direction (counter clockwise direction) is swung, described in contact Lock tongue (40), and when another direction (clockwise direction) swings and resets, it is detached from the lock tongue (40).

This bolt brake block (110) is pivoted about with the fixing axle (16) of shell (10), and the closing piece (111) then protrusion connection forwards, the swing component (112) for protruding connection above are inserted into and are stuck in the bolt limited block (100) on chaining part (103).

At this point, the closing piece (111) and swing component (112) are the shape of idler wheel or rotary shaft, it is braked by bolt The swing of block (110) when contacting support slot (42a) and chaining part (103), in the direction of swing, is realized closing piece (111) and is swung The rotation of part (112).

In addition, the bolt cam (120) include: in the rear side operating handle of the bolt limited block (100), can be with Rotated, the first pressurizing block (122) and the second pressurizing block (123) that the upper and lower sides in front end protrude respectively and it is described first, Between second pressurizing block (122) (123), the thrust block (124) that protrusion height is lower than pressurizing block (122) (123), and described plus Between briquetting (122) (123) and stops (124), the first groove (125) that direction is opposite with stops (124) protrusion direction and Two grooves (126), when terminating bidirectional rotation, one of them in the described 1st, the 2nd pressurizing block (122) (123) is inserted to described Pin limited block (100) pressurizes, and pushes ahead, and in non-rotating and rotation, the bolt limited block (100) contacts institute One of them in stops (124) and first, second groove (125) (126) is stated, after preventing bolt limited block (100) It moves.

Specifically, there is a pair of bolt cam (120) in the two sides of the locked wheel (80), link with each handle Rotation, and be linked on the first axle (130) being connect with indoor handle and the second axis being connect with outdoor handle (140).With rotation Centered on shaft, connection first, second pressurizing block (122) (123) is respectively forwardly protruded in upper and lower sides, first, second adds Protrusion connects the stops (124) between briquetting (122) (123), and has between each pressurizing block (122) (123) and stops (124) First, second groove (125) (126).

For this bolt cam (120) when not having operating handle, the stops (124) contacts the ejector block (101), prevents Only bolt limited block (100) moves backward,

By operating handle, if bolt cam (120) is rotated to a direction, stops (124) is swung, and is detached from ejector block (101) while, ejector block (101) continues to contact the first or second groove (125) (126), prevents bolt limited block (100) Move back,

In this case, when bolt cam (120) stops rotating, the first pressurizing block (122) or the second pressurizing block (123) to It is preceding to pressurize to ejector block (101), it pushes bolt limited block (100).

Therefore, by the closure of door, the sub- lock (30) is in the state of semi-convex, according to the pressing means (35) and institute The pressure releases of one of them in pressurizing block (122) (123) are stated, the bolt limited block (100) just moves backward, meanwhile, make The bolt brake block (110) is swung to one direction, at this point, the closing piece (111) contacts the lock tongue (40) and prevents The bullet of the lock tongue (40) into, realize lock tongue (40) locking,

By operating handle, the unlock of the keeper (20) and sub- lock (30) bullet is completed into the state of pop-up, pass through institute Pressing means (35) or the pressurizing block (122)/(123) pressurization are stated, the bolt limited block (100) then moves forward, together When, the bolt brake block (110) swings in the other direction, at this point, the closing piece (111) starts to be detached from support slot (42a), Allow the bullet of the lock tongue (40) into the unlock of completion lock tongue (40).

Firstly, axis drives locked wheel (80) and the first bolt cam referring to Fig. 4 a to Fig. 4 d to by operating handle (120A) is unidirectionally rotated, and the embodiment for completing door opening and closing is illustrated.

As shown in fig. 4 a, under door closure state, the sub- lock (30) passes through door latch (S) in the state of semi-convex, by The ejector block (101) is supported in the stops (124), therefore, in the pressing means (35) and the pressurizing block (122) (123) any one in, fail to push bolt limited block (100) forward, at this point, the bolt brake block not swung (110) closing piece (111) contacts the support slot (42a), prevents the bullet of lock tongue (40) into the i.e. locking of realization lock tongue (40).

As shown in Figure 4 b, in order to open door, by handle by it is axial counterclockwise rotated when, lock wheel (80) and First bolt cam (120A) also can counterclockwise be rotated, in this way, realizing keeper (20) by above-mentioned escaping function Unlocking function prevents bolt from limiting at this point, the first groove (125) supports ejector block (101) before keeper (20) complete unlock Position block (100) moves back, and the locking of lock tongue (40) is continued to by bolt brake block (110).

As illustrated in fig. 4 c, it when locked wheel (80) and the first bolt cam (120A) stop rotating, i.e., is unlocked in keeper (20) The moment of completion, the first pressurizing block (122) push ahead supporting element (102), meanwhile, by bolt brake block (110) to the inverse time Needle direction is swung, in this way, closing piece (111) be detached from support slot (42a), lock tongue (40) unlock, lock tongue (40) can bullet into.

In this way, lock tongue (40) unlock, door is opened by operating handle, at this point, by door latch (S), lock tongue (40) bullet Into when, be detached from door latch (S), meanwhile, sub- lock (30) and lock tongue (40) are to popping up outside shell (10).

As shown in figure 4d, door is opened, and when decontroling handle, locks wheel (80) and the first bolt cam (120A) to counterclockwise Direction is rotated, and returns to home position, if the first pressurizing block (122) is detached from supporting element (102), bolt limited block (100) it can move backward, but under door opening state, since sub- lock (30) is ejected completely, pressing means (35) then push forwards The ejector block (101), and bolt limited block (100) is in preceding shifting state, therefore, with the continuation of lock tongue (40) unlocked state Keep, when door is closed again, by contact door latch (S), realize son lock (30) and lock tongue (40) bullet into.

At this point, even if son lock (30) bullet into, release promote bolt limited block (100) pressure, due to sub- lock (30) one With bullet into lock tongue (40), the second housing (42) prevents the swing path of closing piece (111), and bolt brake block (110) is unable to get Restore, therefore, lock tongue (40) bullet can just be popped up into rear.

As shown in fig. 4 a, under shutdown state, pass through the son lock (30) of semi-convex and the first bolt cam of reset (120A), bolt limited block (100) move backward, meanwhile, bolt brake block (110) is resetted and is swung clockwise, this Sample, closing piece (111) contact lock tongue (40) support slot (42a) of pop-up again, realize the locking of lock tongue (40), in this case, By the rotation of motor (M), keeper (20) is moved forward, and realizes the locking of keeper (20).

As shown in Fig. 5 a to Fig. 5 d, a kind of embodiment locks wheel (80) and the second bolt is convex by the axis to link with handle Wheel (120B) is rotated to another direction, realizes the opening and closing of door, when the rotation by handle, when being axially rotated clockwise, Locked wheel (80) and the second bolt cam (120B) also rotate clockwise, meanwhile, the second groove (126) and the second pressurization Block (123) and the first groove (125) and the first pressurizing block (122) are mobile to same direction, therefore, real after lock tongue (40) is locked into The opening and closing of existing door,

It opens the door outdoors or when indoor handle does not have an escaping function (drawing does not mark), on the axis to link with outdoor handle Only one of them in link bolt cam (120A) (120B) therefore releases safely process, keeper by Password Input etc. (20) after unlocking, lock that wheel (80) is motionless, and link the bolt cam outdoors on axis to one direction or another direction into Row rotation, at this point, each accessory moves in same manner described above, in this way, realizing the opening and closing of door after lock tongue (40) is locked into.

According to the present invention, it by family inner handle escaping function, opens the door outdoors or indoor handle does not have escaping function When (drawing does not mark), wherein one in bolt cam (120A) (120B) is only linked on the axis to link with outdoor handle It is a, therefore, process is released safely by Password Input etc., after keeper (20) unlock, it is motionless to lock wheel (80), and link outdoors Bolt cam on axis is rotated to one direction or another direction, at this point, each accessory is in same manner described above Movement, in this way, realizing the opening and closing of door after lock tongue (40) is locked into.

Then, the first axle (130) and the second axis (140) are inserted into the indoor one side of mortise lock and the another side of open air respectively On, and connect indoor handle and outdoor handle on each axis and rotate, lateral surface is quadrilateral structure, and this point is same as described above.

But the first connector of inner end of first axle (130) is to correspond to each other with second the second connector of axis inner end Circular configuration, be the combination of inner and outside, and these axis (130) (140) in same axis arrange connection in the state of, mutually carry out Idle running, these and above-mentioned difference.

Here, each connector of these axis (130) (140) is circular configuration, it is the combination of inner and outside, this refers to, in order to have one When a axis rotates, another axis remain stationary state, sets mutual corresponding circular configuration for the lateral surface of each connector.

Typically, the connector of first axle (130) is the outer connector of spherical protrusion, and the second of the second axis (140) Connector then corresponds to the vaulted outer connector, is the interconnecting piece of spherical concave.
