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 connecing for door latch (S) Touching 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 It removes）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：With with 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, this point and above-mentioned sub- lock（30）It has any different.

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)（It is not regarded out in figure）, and it is this Supporting table (41b) is equally applicable on first supporting block (31a).

Then, carrying out bullet into the keeper operating unit (DU) of pop-up to the keeper (20) includes：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.

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 of motion block (110)（112）Sliding link is sent out on chaining part (103) when bolt limited block (100) are moved forward and backward 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）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（Counterclockwise）When swing, described in contact Lock tongue (40), and in another direction（Clockwise）When swinging reset, 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, pass through bolt brake block (110) swing when contacting support slot (42a) and chaining part (103), in the direction of swing, realizes closing piece (111) and swing component (112) rotation.

In addition, the bolt cam (120) includes：Pressurizing block (122), (123), in the bolt limited block (100) When rear side operating handle, it can be rotated, and the bolt cam (120) limits the bolt when one direction rotates Block (100) pressurizes, and moves forward bolt limited block (100), and in another direction spinning reduction, described in release The pressure of bolt limited block (100) moves backward bolt limited block (100).

Specifically, the bolt cam (120) includes the pressurizing block (122) that side is protruded above and below front end (123), and the stops (124) lower than pressurizing block in the other side of the pressurizing block (122) (123), protrusion height, and described Between pressurizing block (122) (123) and stops (124), the groove (125) (126) that direction is opposite with stops (124) protrusion direction. When not rotating and rotating, while the bolt limited block (100) contacts the stops (124) and groove (125) (126), Prevent moving back for bolt limited block (100).

As shown in embodiment a kind of on drawing, there are 2 protruded respectively in the front end upper and lower sides of bolt cam (120) One, the second pressurizing block (122) (123), and have the first, second groove between each pressurizing block (122) (123) and stops (124) (125) (126), the first pressurizing block (122) and the first groove (125) or the can be set according to the direction of rotation of axis in these Wherein one group in two pressurizing blocks (123) and the second groove (126), the related technical personnel of the industry can be easy as a result, The technology of the present invention feature is realized, in order to facilitate understanding content, below around setting pressurizing block (122) (123) and groove (125) (126) bolt cam (120) is illustrated the core of invention.

Firstly, the bolt cam (120) is in no operating handle, i.e., axis does not rotate and bolt cam (120) does not revolve In the state of turning, the stops (124) contacts the ejector block (101), prevents bolt limited block (100) from moving backward.

By operating handle, if bolt cam (120) is rotated to a direction, stops (124) is swung, and is detached from and is pushed away Ejector block (101) continues to contact the first or second groove (125) (126) while part block (101), 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) it pressurizes forward, pushes bolt limited block (100) to ejector block (101).

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, while making institute It states bolt brake block (110) to be swung to one direction, at this point, the closing piece (111) contacts the lock tongue (40) and prevents institute The bullet of lock tongue (40) is stated into realizing the locking of lock tongue (40).

By operating handle, complete sub- lock (30) bullet into the state of pop-up, by the pressing means (35) or The pressurizing block（122）/（123）Pressurization, the bolt limited block (100) then moves forward, meanwhile, the bolt brake block (110) it swings in the other direction, at this point, the closing piece (111) starts to be detached from support slot（42a）, allow the lock tongue (40) Bullet into, complete lock tongue (40) unlock.

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.
