The present invention provides door lock mortise lock（M）, including：Mortise lock main part（10）, keeper（20）, sub- lock (30), lock tongue（40）, behaviour Make device（50）And locker（70）.

Detailed construction is as follows, the mortise lock main part（10）It is built on door, has door in the overhanging sidewall end in door end (11) Bolt (20), card end (21), the first head (31) of sub- lock (30), lock tongue (40) the second head (41), carry out respectively it is flexible First to third telescopic hole（113）.

Will not be restricted for the quantity of each telescopic hole, but in order to reinforce the locking function of keeper (20), door of the invention Have 3 card ends (21) on bolt (20), equally, upper and lower has 3 the first telescopic holes (111), and son lock (30) and lock tongue (40) and Second telescopic hole (112) and third telescopic hole (113）There are one only.

Accordingly, with respect to the sidewall end (11), there is the card end for being inserted into the keeper (20) on the door latch (S) of doorframe (21) and the lockhole on (40) second head (41) of the lock tongue, correspond to the sub- lock（30）The part on the first head (31) is Non-porous flat shape, under door locking state, (30) first head (31) of the sub- lock springs into the mortise lock main part（10）On.

In addition, have the guiding axis (13) that guiding keeper (20) is moved forward and backward inside the mortise lock main part (10), also one A little individual fixing axles rotated or each structural member is chatted after fixed, these are the technology having disclosed, and are no longer illustrated herein.

The keeper (20) is used for the locking and unlock of door, there is keep certain distance to be attached up and down 2 in front end Above card end (21)（The present invention lists 3 card ends（21））, and middle-end either has described in connection on rear end or the both ends The sliding eye (23) of guiding axis (13)（Structure of the invention is two guiding axis（13）And sliding eye（23）, can stablize into Row linear motion）.

This keeper (20) by (using manual key by indoor handle with escaping function or outdoors manually Deng user can directly operate) or motor (512) operation（It indoors presses door open button or inputs password outdoors Or card safe to use, fingerprint etc., it is run after unlock）, it is moved forward and backward on mortise lock main part (10), and the card end (21) is in institute It states and snaps into pop-up on the first telescopic hole (111), stretched or sprung into mortise lock main part (10) outside.

Then, sub- lock（30）And lock tongue（40）The door latch that doorframe is contacted when door is opened and closed, from mortise lock main part（10）It is enterprising Row snaps into pop-up, at this point, each head is to mortise lock main part（10）Outside stretch.

Specifically, first, the sub- lock（30）Including：First head（31）, pass through second telescopic hole（112）, can With to mortise lock main part（10）Outside stretch；The first housing（33）, it is connected to first head（31）, to ejection direction Resilient support, meanwhile, in mortise lock main part（10）Inside be moved forward and backward；First axle pin（35）, described in hinge connection One head（31）With the first housing（33）, make first head（31）It swings.

This seed is locked（30）The first housing（33）Rear end have the first elastomer（37）, first elastomer（37）'s There is first support in end（371）, pass through the first elastomer（37）Elasticity, sub- lock（30）By forward elastic force.

In addition, the sub- lock（30）Door latch is contacted, realizes first head（31）Bullet is completed in the conversion of left and right directions Into the action of pop-up.

For this purpose, first head (31) is by symmetrical the first inclined-plane (311) and the second inclined-plane（312）Composition, it Stretch out the outsides of mortise lock main part (10), front and back sides tilt down forward, when door is opened and closed, according to the side of contact door latch To the first head (31) are swung centered on first axle pin (35), realize the first inclined-plane (311) and second tiltedly Face（312）Direction switching.

Therefore, the upper surface of described first head (31) either below or their top and bottom have along it is described first cut with scissors The first supporting block of semicircle that the rear side outer rim of chain pin (35) is protruded（314）, in this way, first head（31）Pop-up When, contact the mortise lock main part（10）Sidewall end（11）, first head（31）When snapping into, with the mortise lock main part（10） The first supporting block (314) end of side is supporting point, realizes the first head（31）Swing.

Opened that is, first, under door closure state or door open state under close after, if first head (31) connects When touching door latch, the first head (31) swung in the negative direction of contact, meanwhile, each oblique tube by contacting doorframe inclines The inside of mortise lock main part (10) is got into gradient, the first head (31), at this point, son lock (30) is snapped into.

At this point, one of in the first supporting block (314) both-side ends for contacting the sidewall end (11)（It sets In the end of the first head (31) swaying direction）, a kind of supporting point similar to lever is generated, meanwhile, disperse or resists the One supporting block (314) is applied to the impact of the first head (31), and speed more faster than sub- lock (30) snaps into mortise lock main part (10) Inside, to the breakage etc. of accessory for preventing impact from bringing.

In addition, first supporting block (314) is when first head (31) is popped up, first supporting block (314) End contact the sidewall end (11) of the mortise lock (10), so that first head (31) is returned to the position before swinging.

That is, in the state that door completely disengages doorframe and opens, first head (31) will produce external force, at this point, described Son lock (30) is moved forward and is popped up by first elastomer (37), and the first head (31) carry out in some direction of left and right It is ejected in the state of swing, therefore, when pop-up, contact one of in the both-side ends of first supporting block (314) The sidewall end (11) generates the supporting point similar to lever, and then, using the supporting point as rotary shaft, the first head (31) are returned Original position before to swing, that is, son lock (30) pop-up is realized in the neutral position before not swinging, in this way, not only limiting the The pop-up distance on one head (31), moreover, in this case, when the door is closed, institute is compared on the second head (41) of lock tongue (40) It states the first head (31) and first contacts door latch, lock tongue (30) is made to snap into than sub- lock (40) earlier.

Next, the lock tongue (40) can stretch to mortise lock main part (10) is external, including, it is carried out to ejection direction The second head (41) of resilient support.

Specifically, the lock tongue (40) includes that can carry out the second flexible head to the third telescopic hole (113) (41)；Be connected to second head (41), flexibly supported to ejection direction, and move mortise lock main part (10) is internal front and back The dynamic second housing (43)；With the second head (41) described in hinge connection and the second housing (43) so that described second The second hinge pin (45) that portion (41) swings；There is individual locker at the rear of the second housing (43) （70）, described further below.

This lock tongue (40) according to the second elastomer (47) in mortise lock main part (10) to ejection direction by elastic pressurized, It is identical as sub- lock (30), by the contact of door latch, the left and right directions switching of second head (41) is completed, bullet is carried out 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, it shakes at closing time in order to prevent, is supported in the state of the second housing (43), is arranged up and down, and Centered on the second hinge pin (45), the inclined-plane being oppositely arranged is made of a pair of of fission that cross is formed, when door is opened When closing, swung one of in fission, meanwhile, the second head (41) rear carries out snapping into pop-up forward.

That is, supported by the second housing (43) at the seperated each back side of a pair of composition the second head (41), and shared second In the state of joint pin (45), each lateral surface is arranged in parallel in the lateral direction, meanwhile, each medial surface is with X-shaped shape X-shape At therefore, as long as lock tongue (40) does not snap into, each fission cannot swing, and can not thus open the door, only lock tongue (40) It is snapped into, can just be swung one of in fission, meanwhile, by the pressure snapped into, the second head (41) can just snap into, that is, lock Tongue (40) can just move backward.

For example, when opening the door, if the lateral surface of first seperated (411) contacts door latch, the second housing (43) will be backward Passage makes the first fission at this point, first seperated (411) (412) seperated with second are swung with identical angle（411）With The lateral surface of second seperated (412) contacts door latch with medial surface, to which the second head (41) squeeze into mortise lock main part (10) Inside, in this way, lock tongue (40) is snapped into inside.

Therefore, each fission of second head (41) includes：Second supporting block（414）, in the top and bottom of each fission, edge The second hinge pin（45）Rear side outer rim protruded, on the second head（41）When pop-up, the mortise lock main part is contacted （10）Sidewall end（11）, second head（31）When snapping into, the fission of swing is with the mortise lock main part（10）Sidewall end （11）The second supporting block (414) end be that supporting point is swung, when the second head (41) pop ups, the of the fission of swing Two supporting blocks (414) end contacts the sidewall end (11) of the mortise lock main part (10), meanwhile, corresponding seperated recovery is to before swinging Original position.

That is, this second supporting block（414）With the sub- lock（30）The first supporting block（314）Corresponding structure, tool Body function and the first supporting block above-mentioned（314）It is identical, still, when the first head (31) of sub- lock (30) is ejected, pass through One supporting block (314) returns to neutral position, and when the second head (41) of lock tongue (40) is ejected, pass through the second supporting block (414), each fission will be returned to the position of intersection, and this point is had any different with above-mentioned.

At this point, the first supporting block (314) is subject to the neutral position of the first head (31), both ends contacting side wall end (11), And the second supporting block (414) is subject to each seperated swing position intersected, both ends contacting side wall end (11).

Therefore, in order to which the swing of each fission resets and steadily supports, the both ends of the second supporting block (414) have and sidewall end (11) identical in terms of plane, and the supporting table (415) of lateral bend connection outward, and this supporting table (415) is equally applicable to On first supporting block (314).

Then, to keeper（20）Snap into the keeper operator of pop-up（50）It illustrates.

The operator（50）Including driving keeper（20）Operating parts, the operating parts（51）Fig. 1 is subject to, to up time Needle direction is rotated, can be by keeper（20）Spring into sidewall end（11）Inside.

That is, in the operating parts（51）Side can pressurize the keeper（20）The impeller of rear side（25）, when described Operating parts（51）When rotating clockwise, the operating parts（51）Push the impeller（25）, make impeller（25）It moves backward, Realize snapping into for keeper.

At this point, the operating parts（51）The separator chatted after（60）Rotation（When using escaping function）, Ke Yijin Row activity, still, this is limited to escaping function, therefore, and under normal conditions, is known by manual key or fingerprint in outside Not, Password Input etc., drive motor（512）It could unlock.

For this purpose, the operating parts（51）On have the handle connecting hole that can connect manual key or handle（511）, this is For manual rotary operation part（51）And be arranged, and when outside unlocks, drive motor（512）With the motor（512）On The first gear of setting（514）, the first gear（514）With second gear（515）Engagement connection, makes to be connected to the operation Part（51）On second gear（515）Drive operating parts（51）It is rotated.

For this purpose, the operating parts（51）On have fixture block（517）, and the second gear（515）On have and be inserted into the fixture block （517）Drive hole（515a）, when the second gear（515）When rotation, the drive hole（515a）End push described in Fixture block（517）And it is rotated.

Therefore, in order to make to snap into the mortise lock main part（10）On keeper（20）There are recuperability, the keeper（20）It is upper to go back There is curved spring（15）, make keeper（20）Return to original position, the operating parts of the rotation（51）Also original position can be returned to.

It is a feature of the present invention that further including locker, work as door locking prevents the lock tongue when sub- lock (30) is snapped into (40) snap into.

In more detail, the locker（70）Can link sub- lock（30）The first housing（33）And lock tongue（40）? Two bodies（43）, locker（70）Including locking body（71）, and locking body（71）Including penetrating through the first housing（33）Pass through Through-hole（711）With snap into the second housing（43）Snap into mouth（713）.

In more detail, the first housing（33）On have the oblique tube declined forwards（331）, and penetrate through the oblique tube （331）Through hole（711）It is arranged on the locking body.

In conclusion working as the sub- lock（30）When snapping into, the first housing（33）It moves backward, at this point, described first Body（33）It can pass through in the locking body（71）The through hole of upper setting（711）.

Therefore, with the locking body（71）Decline, limit the lock tongue（40）Snap into, thus, it is preferable that locking Tight body（71）Top be arranged third elastomer（73）, the locking body can be made by elasticity（71）It moves down.

Under the door closure state, the sub- lock（30）Snap into mortise lock main part（10）Inside, at this point, the oblique tube （331）It is in the through hole（711）Rear, the locking body（71）Decline, limits lock tongue（40）Snap into, when open door When, the sub- lock（30）It moves forward, at this point, the first housing（33）Oblique tube（331）It is moved to the through hole （711）Front end, and the through hole（711）The upper surface of along the oblique tube（331）Risen, therefore, generally speaking, Play promotion locking body（71）Effect.

That is, the locking body risen in this way（71）, eliminate and limit the lock tongue（40）The device snapped into can make lock tongue （40）Snap into mortise lock main part（10）Inside.

For the locking body（71）Prevent lock tongue（40）The device sprung into, first, the locking body（71）Lower section have The second housing of the lock tongue can be snapped into（43）Snap into mouth（713）.Meanwhile the second housing（43）On have locking step （431）, when the locking body（71）It is described to snap into mouth when decline（713）Upper end be adjacent to the second housing（43）The upper surface of, this When, the locking step（413）It is stuck in and snaps into mouth（713）On, make it that can not snap into, to prevent snapping into for lock tongue.

On the contrary, working as the locking body（71）It is described to snap into mouth when rising（713）The upper surface of far from the second housing, root According to this separated by a distance, it can be ensured that the locking step（431）Into snapping into mouth（713）Space, constitute allow lock tongue （40）The structure snapped into.
