The present invention provides door lock mortise lock (M), comprising: mortise lock main part (10), keeper (20), sub- lock (30), lock tongue (40), behaviour Workpiece (50) and locker (70).

Detailed construction is as follows, and the mortise lock main part (10) 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 flexible respectively One 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) only one.

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

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

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

This keeper (20) by manually (by the indoor handle with escaping function or outdoors using manual key etc., User can directly operate) either motor (512) operation (indoors press door open button or outdoors input password or Using safety card, fingerprint etc., run after unlock), it is moved forward and backward on mortise lock main part (10), and the card end (21) is described Bullet is stretched or is sprung into mortise lock main part (10) outside into pop-up on one telescopic hole (111).

Then, sub- lock (30) and lock tongue (40) contact the door latch of doorframe when door is opened and closed, enterprising from mortise lock main part (10) Row bullet into pop-up, meanwhile, the head of the sub- lock (30) and the lock tongue (40) is stretched to the outside of mortise lock main part (10).

It specifically,, can by second telescopic hole (112) firstly, the sub- lock (30) includes: the first head (31) To stretch to the outside of mortise lock main part (10)；The first housing (33) is connected to first head (31), to ejection direction Resilient support, meanwhile, it is moved forward and backward in the inside of mortise lock main part (10)；First axle pin (35), hinge connection described the One head (31) and the first housing (33) make first head (31) swing.

The rear end of the first housing (33) of this seed lock (30) has the first elastomer (37), first elastomer (37) End has first support (371), and by the elasticity of the first elastomer (37), sub- lock (30) is by forward elastic force.

In addition, the sub- lock (30) contacts door latch, the conversion of the first head (31) left and right directions is realized, complete bullet Into the movement of pop-up.

For this purpose, first head (31) is made of symmetrical the first inclined-plane (311) and the second inclined-plane (312), the The outside of mortise lock main part (10) is stretched out in one inclined-plane (311) and the second inclined-plane (312), and front and back sides tilt down forward, works as door When opening and closing, according to the direction of contact door latch, the first head (31) are swung centered on first axle pin (35), Realize the direction switching of the first inclined-plane (311) and the second inclined-plane (312).

Therefore, the upper surface of described first head (31) or below or their top and bottom have along first hinge The first supporting block of semicircle (314) that the rear side outer rim of chain pin (35) is protruded, in this way, first head (31) is popped up When, contact the sidewall end (11) of the mortise lock main part (10), the first head (31) bullet into when, with the mortise lock main part (10) The first supporting block (314) end of side is supporting point, realizes swinging for the first head (31).

That is, firstly, under door closure state open or door open state under close after, if first head (31) connects When touching door latch, the first head (31) swung in the opposite 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), meanwhile, sub- lock (30) by bullet into.

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

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, first head (31) can generate external force, at this point, described in the state that door completely disengages doorframe and opens Son lock (30) is moved forward and is popped up by first elastomer (37), at this point, the first head (31) are in some side of left and right Be ejected in the state of being swung, therefore, when pop-up, in the both-side ends of first supporting block (314) wherein one A contact sidewall end (11), generates the supporting point for being similar to lever, then, using the supporting point as rotary shaft, the first head (31) original position before swinging is returned to, that is, son lock (30) pop-up is realized, in this way, not only in the neutral position before not swinging The pop-up distance on the first head (31) is limited, moreover, in this case, when the door is closed, the second head of lock tongue (40) (41) door latch is first contacted than first head (31), makes lock tongue (30) bullet into earlier than sub- lock (40).

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), and it is connected to second head (41), is flexibly supported to ejection direction, and moved in the internal front and back of mortise lock main part (10) The dynamic second housing (43) and hinge connect second head (41) 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, it, can be on the front of the second housing (43) in the state of being supported Under arranged, and centered on the second hinge pin (45), a pair point that the inclined-plane being oppositely arranged is formed by cross Body composition, when door opening and closing when, fission in one of them swung, meanwhile, the second head (41) forward rear carry out bullet into Pop-up.

That is, each back side of a pair of fission of composition the second head (41) is supported by the second housing (43), and shared second hinge In the state of chain pin (45), each lateral surface is arranged in parallel in the lateral direction, meanwhile, each medial surface is intersected to form with X-shaped shape, Therefore, if lock tongue (40) not bullet into each fission cannot swing, and can not thus open the door, only lock tongue (40) quilt Bullet into, one can just swing in the base in fission, meanwhile, by bullet into pressure, the second head (41) could bullet into i.e. lock tongue (40) it can just move backward.

For example, if, the outside face contact door latch of first seperated (411), the second housing (43) will be backward when opening the door Passage, meanwhile, first seperated (411) (412) seperated with second are swung with identical angle, make the first fission (411) and The lateral surface and medial surface of second seperated (412) contact door latch, thus, the second head (41) squeeze into mortise lock main part (10) Inside, in this way, lock tongue (40) is by bullet into inside.

Therefore, each fission of second head (41) includes: the second supporting block (414), in the top and bottom of each fission, edge The rear side outer rim of the second hinge pin (45) protruded, when the second head (41) are popped up, contact the mortise lock main part (10) sidewall end (11).

First head (31) bullet into when, seperated second with mortise lock main part (10) sidewall end (11) of swing Bracer (414) end is that supporting point is swung, when the second head (41) pop-up, the second seperated supporting block of swing (414) end contacts the sidewall end (11) of the mortise lock main part (10), meanwhile, the corresponding seperated original position restored to before swinging.

That is, this second supporting block (414) structure corresponding with the first supporting block (314) of the sub- lock (30), tool Body function is identical as the first supporting block (314) above-mentioned, still, when the first head (31) of sub- lock (30) is ejected, passes through One supporting block (314) returns to neutral position, on the contrary, passing through the second support when the second head (41) of lock tongue (40) is ejected 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), On the contrary, the second supporting block (414) is subject to each seperated swing position intersected, both ends contacting side wall end (11).

Therefore, it resets for the swing of each fission 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, bullet is carried out to keeper (20) to be illustrated into the operator (50) of pop-up.

The operator (50) includes the operating parts (51) for driving keeper (20), and the operating parts (51) is subject to Fig. 1, to It is rotated clockwise, keeper (20) can be sprung into the inside of sidewall end (11).

That is, can pressurize the impeller (25) on rear side of the keeper (20) in the side of the operating parts (51), when described When operating parts (51) rotates clockwise, the operating parts (51) pushes the impeller (25), moves backward impeller (25), Realize keeper bullet into.

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

For this purpose, there is the handle connecting hole (511) that can connect manual key or handle on the operating parts (51), this is It is arranged for manual rotary operation part (51), and in outside unlock, the motor (512) driven after identification and the motor (512) first gear (514) being arranged on is engaged with the first gear (514), makes to be connected to the operating parts (51) second gear (515) on drives operating parts (51) to be rotated.

For this purpose, there are fixture block (517) on the operating parts (51), and there is the insertion fixture block in the second gear (515) (517) drive hole (515a), when the second gear (515) rotation, described in the end promotion of the drive hole (515a) Fixture block (517) is simultaneously rotated.

Therefore, it in order to make bullet have recuperability into the keeper (20) on the mortise lock main part (10), is gone back on the keeper (20) There are curved spring (15), original position is returned to according to keeper (20), the operating parts (51) of the rotation can also return to original position.

The indoor handle escaping function of core of the present invention is described in detail below.

Firstly, the escaping function refers to, in case of emergency, when rotating indoor handle, link and spring into keeper (20) and Lock tongue (40), the function that user can open the door easily, it is characterized in that, indoor handle is rotated in any case, can be opened the door, it can be with Escaping function is realized easily.

For this purpose, the separator (60) includes Handle axis (61) and the Handle axis the invention also includes separator (60) (61) the escape rotor (63) and bolt rotor (65) being arranged on.

Firstly, the separator (60) is connected in inside handle, including escape rotor (63) and bolt rotor (65), the separator (60) can be inserted.

The pressurizing block (631) of oriented side protrusion on escape rotor (63), when the separator (60) rotate When, the pressurizing block (631) also rotates together, and operating parts (51) can be driven to be rotated.

In more detail, the operating parts (51), the operator are driven in order to pass through the rotation of the separator (60) (50) there are also the first linkage gear (53) and the second linkage gears (54) on.

First linkage gear (53) and the second linkage gear (54) are arranged in the top of the separator (60), they Driving can be engaged, the lower section of first linkage gear (53) and the second linkage gear (54) there are first handle (531) respectively With second handle (541), and second pressurizing block (631) pushes first handle (531) or second handle.

That is, pressurizing block (631) are arranged among the first handle (531) and second handle (541).

Therefore, there is the abutting stem (533) for rotating the operating parts (51) on the end of first linkage gear (53), because This, when the first linkage gear (53) is rotated clockwise, the abutting stem (533) pushes the operating parts (51) At lower-left, rotate operating parts (51) clockwise, realize the bullet of keeper into.

That is, if keeper (20) will bullet into, first linkage gear (53) must be rotated clockwise, this After the first linkage gear (53) and the second linkage gear (54) engagement of invention, regardless of how separator (60) rotate, make always First linkage gear (53) is rotated clockwise.

In more detail, if the separator (60) is rotated counterclockwise, the pressurizing block (631) is to suitable Clockwise pushes first handle (531), and the first linkage gear (53) is rotated clockwise as a result,

When pushing the separator (60) clockwise, the pressurizing block (631) makes second handle (541) to side counterclockwise To being rotated, at this point, the first linkage gear (53) being engaged with second linkage gear (54) is according to engaging structure, Naturally it is rotated clockwise.

Moreover it is preferred that in order to make first linkage gear (53) and the second linkage gear (54) have recuperability, by One elastic component (56) is connected on the first linkage gear (53) and the second linkage gear (54).

Therefore, when user needs to open the door, as long as rotary separator (60), can open door, to improve ease of use.

Therefore, it is a feature of the present invention that further including locker (70), work as door locking, sub- lock (30) by bullet into when, prevent The bullet of the lock tongue (40) into.

In more detail, the locker (70) can link sub- lock (30) the first housing (33) and lock tongue (40) second Body (43), including, locking body (71), and locking body (71) include the first housing (33) perforation through hole (711) and Bullet import (713) of the bullet into the second housing (43).

In more detail, there is the oblique tube (331) declined forwards on the first housing (33), and penetrate through the oblique tube (331) through hole (711) is arranged on the locking body (71).

In conclusion when sub- lock (30) bullet into when, the first housing (33) moves backward, at this point, described first Body (33) can pass through the through hole (711) being arranged on the locking body (71).

Therefore, with the decline of the locking body (71), the bullet of the lock tongue (40) is limited into thus, it is preferable that locking Third elastomer (73) are arranged in the top of tight body (71), the locking body (71) can be made to move down by elasticity.

Under the door closure state, sub- lock (30) bullet into mortise lock main part (10) inside, at this point, the oblique tube (331) be in the rear of the through hole (711), locking body (71) decline, limit the bullet of lock tongue (40) into,

When unlocking the door, the sub- lock (30) moves forward, at this point, the oblique tube (331) of the first housing (33) is moved to The front end of the through hole (711), and the upper surface of described through hole (711) is risen along the oblique tube (331), because This generally speaking plays the effect for promoting locking body (71).That is, the locking body (71) risen in this way, is eliminated described in limitation Lock tongue (40) bullet into device, lock tongue (40) bullet can be made into the inside of mortise lock main part (10).

Therefore, the device for preventing lock tongue (40) from springing into the locking body (71), firstly, under the locking body (71) Side have can bullet into the lock tongue the second housing (43) bullet import (713).

At this point, have locking step (431) on the second housing (43), and when the locking body (71) decline, the bullet The upper end of import (713) is adjacent to the upper surface of second housing (43), at this point, the locking step (413), which is stuck in, plays import (713) On, make its can not bullet into, thus, prevent the bullet of lock tongue into.

On the contrary, the upper surface of described bullet import (713) is far from the second housing when the locking body (71) rise (43), according to this separated by a distance, it can be ensured that locking step (413) enters the space for playing import (713), constitutes and permits Perhaps lock tongue (40) bullet into structure.

Therefore, when keeper (20) move back (unlock) complete before, lock tongue (40) bullet into when, can when opening the door unreasonable Keeper can occur and lock the problems such as serious.

Therefore, before the keeper (20) moves back completion, the bullet of the lock tongue (40) is into should be arranged in order to prevent Time difference, by this time difference, can make locking body (71) rise time than keeper (20) bullet into the time more slowly, this hair It is bright by lock release device (80), can solve these problems.

Firstly, in order to allow the bullet of sub- lock (30) and lock tongue (40) into the lock release device (80) promotes the decline Locking body (71), this movement and the movement of the separator (60) are contacted.

For this purpose, the lock release device (80) includes carrying out with the movement of the bolt rotor (65) of the separator (60) The first STATEMENT OF FEDERALLY SPONSORED (81) and the second STATEMENT OF FEDERALLY SPONSORED (83) of linkage, these first STATEMENT OF FEDERALLY SPONSOREDs (81) and the second STATEMENT OF FEDERALLY SPONSORED (83) pass through Gear is engaged and rotates.

In addition, there is the first fastener in the side of the side of first STATEMENT OF FEDERALLY SPONSORED (81) and the second STATEMENT OF FEDERALLY SPONSORED (83) respectively (811) and the second fastener (831), there is the bolt rotor (65) between these first fasteners (811) and the second fastener (831) Card rod (651).

In addition, the other side of first STATEMENT OF FEDERALLY SPONSORED (81) has lifting lead part (813), the lifting lead part (813) It is inserted into the through-hole (715) of the locking body (71).

Therefore, when first STATEMENT OF FEDERALLY SPONSORED (81) rotates clockwise, the lifting lead part (813) is by through-hole (715) Top pushes up, at this point, locking body (71) rises, allows moving backward for the sub- lock (30) and lock tongue (40) as a result,.

Therefore, separator of the invention (60) both direction can rotate, for this purpose, institute's lock release device (80) First STATEMENT OF FEDERALLY SPONSORED (81) is similarly the structure that gear engages with the second STATEMENT OF FEDERALLY SPONSORED (83).

That is, the purpose of the present invention rotates the first STATEMENT OF FEDERALLY SPONSORED (81) clockwise, when separator (60) inverse time When needle direction is rotated, the card rod (651) of the bolt rotor (65) on the separator (60) pushes first linkage The first fastener (811) of part (81), the first STATEMENT OF FEDERALLY SPONSORED (81) can be moved counterclockwise as a result,

When the separator (60) is rotated counterclockwise, the card rod (651) pushes second fastener (831), the second STATEMENT OF FEDERALLY SPONSORED (83) is rotated counterclockwise, and the first STATEMENT OF FEDERALLY SPONSORED (81) engaged is again to suitable Clockwise is rotated.

The deadlock phenomenon of present invention keeper (20) in order to prevent, needs to be arranged some time differences, for this purpose, the bolt rotates Have on body (65) rodlike card rod (651), the card rod (651) pushes first fastener (811) or the second fastener (831) Middle section, and insertion first fastener in spacer region (653) between the card rod (651) and separator (60) (811) or the end of the second fastener (831).

For this structure, there is a pair of of bolt rotor (65) on the separator (60), and in the bolt rotor (65) side is protruded, and connects the rodlike card rod (651) of protruding part end, and the escape rotor (63) is inserted the pair of Triplen is formed between pin rotor (65).

That is, card rod (651) promotion first fastener (811) (it is illustrated by taking the first fastener (811) as an example, the Two fasteners (831) are identical as the first fastener (811)) intermediate region when, the card rod (651) contact the first fastener (811) Time than the separator (60) push the first or second linkage gear (54) time it is slow, therefore, locking body (71) it is upper The liter time started is slower than keeper (20) unlock time started, thus, prevent the deadlock phenomenon occurred on keeper (20).

These are set back it is therefore preferred that being arranged again in first STATEMENT OF FEDERALLY SPONSORED (81) and the second STATEMENT OF FEDERALLY SPONSORED (83) The second elastic component (85) set improves ease of use.

More than, referring to drawing of the invention, the door lock mortise lock with specific modality and structure is illustrated, but this hair Bright person of an ordinary skill in the technical field can carry out various modifications and change in technical idea and range of the invention More, these deformations and change all belong to the scope of protection of the present invention.
