Fig. 6a shows the state in which the door is opened, Fig. 6b shows the stage in which the rotary separator is unlocked, that is, the stage in which the bolt is unlocked for locking the door, and Fig. 6c shows the state in which the door is locked. The structure is explained in detail.

The present invention provides a door lock mortise lock (M), comprising: a mortise lock main part (10), a door bolt (20), a sub-lock (30), a deadbolt (40), an operating member (50) and a locking device (70) ).

The detailed structure is as follows, the main part (10) of the mortise lock is built into the door, and the door bolt (20), the card end (21) and the first part of the sub-lock (30) are arranged on the side wall end (11) extending outward from the door end. A head (31) and the second head (41) of the locking tongue (40) are respectively the first to third telescopic holes (113) for telescopic expansion.

There is no limit to the number of each expansion hole, but in order to strengthen the locking function of the door bolt (20), the door bolt (20) of the present invention has three clamping ends (21), and similarly, there are three third There is a telescopic hole (111), and there is only one sub-lock (30), lock tongue (40), second telescopic hole (112) and third telescopic hole (113).

Therefore, relative to the side wall end (11), the door latch of the door frame has a clip end (21) for inserting the door bolt (20) and a second head (41) of the latch bolt (40). while the part corresponding to the first head (31) of the sub-lock (30) is a non-porous plane shape, in the locked state of the door, the first head (31) of the sub-lock (30) ) into the mortise lock main part (10).

In addition, the mortise lock main part (10) has a guide shaft (13) for guiding the bolt (20) to move back and forth, and there are also some separate fixed shafts for rotating or fixing the structural parts described later, which have been disclosed. technology, which will not be described here.

The door bolt (20) is used for locking and unlocking the door, and at the front end there are more than two card ends (21) that are connected at a certain distance up and down (the present invention lists three card ends (21)), The middle end or the rear end or the two ends are provided with a sliding hole (23) connecting the guide shaft (13). (The structure of the present invention is two of the guide shafts (13) and the sliding hole (23), which can stably perform linear motion)

This door bolt (20) is operated manually (by an indoor handle with an escape function or using a manual key outdoors, etc., the user can directly operate) or the operation of the motor (512) (pressing the door opening button indoors or inputting it outdoors password or use a security card, fingerprint, etc., and run after unlocking), move back and forth on the mortise lock main part (10), and the card end (21) bounces in and out on the first telescopic hole (111), towards the The outside of the mortise lock main part (10) is retractable or popped in.

Next, the sub-lock (30) and the deadbolt (40) contact the door latch of the door frame when the door is opened and closed, and are ejected from the main mortise lock (10). At the same time, the sub-lock (30) and all The head of the lock tongue (40) is extended and retracted to the outside of the mortise lock main component (10).

Specifically, first, the sub-lock (30) includes: a first head (31), through which the second telescopic hole (112) can be extended and retracted to the outside of the mortise lock main component (10); a first body (33), connected to the first head (31), elastically supported in the direction of ejection, and at the same time, moves back and forth inside the main mortise lock (10); the first hinge pin (35) is hinged to connect the The first head (31) and the first body (33) make the first head (31) swing left and right.

The rear end of the first body (33) of the sub-lock (30) is provided with a first elastic body (37), and the end of the first elastic body (37) is provided with a first bracket (371), through which the first elastic body (37) is provided. The elasticity of (37), the sub-lock (30) is subjected to a forward elastic force.

In addition, the sub-lock (30) contacts the door lock catch, realizes the conversion of the left and right directions of the first head (31), and completes the action of popping in and out.

To this end, the first head (31) is composed of a first inclined surface (311) and a second inclined surface (312) that are symmetrical to each other, and the first inclined surface (311) and the second inclined surface (312) protrude from the main part of the mortise lock On the outside of (10), the front and rear sides are inclined downward toward the front. When the door is opened and closed, according to the direction of contacting the door lock, the first head (31) swings left and right around the first hinge pin (35) to achieve The directions of the first slope (311) and the second slope (312) are switched.

Therefore, a semicircular first support block ( 314), in this way, when the first head (31) is ejected, it contacts the side wall end (11) of the main mortise lock (10), and when the first head (31) is ejected, so The end of the first support block (314) on the side surface of the mortise lock main component (10) is a support point, so as to realize the left and right swing of the first head (31).

That is, first, after the door is opened in the closed state or closed in the open state, if the first head (31) contacts the door latch, the first head (31) swings in the opposite direction of the contact, and at the same time, By contacting the inclination of each inclined member of the door frame, the first head (31) squeezes into the interior of the main mortise lock (10), and at the same time, the sub-lock (30) is ejected.

At this time, at one of the two ends of the first support block (314) contacting the side wall end (11) (the end placed in the swing direction of the first head (31)), a similar At the support point of the lever, at the same time, it disperses or resists the impact exerted by the first support block (314) on the first head (31), and bounces into the main mortise lock (10) at a faster speed than the sub-lock (30). inside, thereby preventing damage to accessories caused by impact.

In addition, when the first head portion (31) is ejected from the first support block (314), the end of the first support block (314) contacts the side wall end (11) of the mortise lock (10). , so that the first head (31) returns to the position before swinging.

That is, when the door is completely separated from the door frame and opened, the first head (31) will generate an external force. At this time, the sub-lock (30) moves forward and pops out through the first elastic body (37). , at this time, the first head (31) is ejected in a state of swinging in one of the left and right directions. Therefore, when ejected, one of the two ends of the first support block (314) contacts the side The wall end (11) produces a support point similar to a lever, and then, with the support point as the axis of rotation, the first head (31) returns to the original position before swinging, that is, the neutral position before swinging left and right, to achieve The sub-lock (30) is ejected, so that not only the ejection distance of the first head (31) is limited, but also, in this state, when the door is closed, the second head (41) of the bolt (40) is more The first head (31) contacts the door lock first, so that the lock tongue (30) springs in earlier than the sub-lock (40).

Next, the locking tongue (40) can be extended and retracted to the outside of the mortise lock main component (10), including a second head (41) that is elastically supported in the ejecting direction.

Specifically, the locking tongue (40) includes a second head (41) that can be extended and retracted toward the third telescopic hole (113), and is connected to the second head (41) and is directed toward the ejection direction A second body (43) that is elastically supported and moves back and forth inside the mortise lock main component (10), and a hinge connecting the second head (41) and the second body (43), so that the second body (43) The second hinge pin (45) for the head (41) to swing left and right; there is a separate lock (70) behind the second body (43), which will be described in detail below.

The lock tongue (40) is elastically pressurized in the ejecting direction according to the second elastic body (47) in the main mortise lock (10), and is the same as the sub-lock (30), through the contact of the door latch, The left-right direction switching of the second head (41) is completed, and the pop-in and pop-up are performed.

Therefore, the shape of the second head (41) of the lock tongue (40) can be the same as that of the first head (31) of the sub-lock (30). However, in order to prevent shaking when the door is closed, the supported state It can be arranged up and down in front of the second body (43), and with the second hinge pin (45) as the center, the oppositely arranged slopes are composed of a pair of splits formed by crossing the left and right sides. When closed, one of the split bodies swings, and at the same time, the second head (41) bounces forward and backward.

That is, in a state where the back surfaces of the pair of separate bodies constituting the second head (41) are supported by the second body (43) and share the second hinge pin (45), the outer surfaces are arranged in parallel in the left-right direction, and at the same time, Each inner side is crossed in the shape of "X", therefore, as long as the lock tongue (40) does not spring in, the separate parts cannot swing left and right, so that the door cannot be opened, only the lock tongue (40) is bounced in, and the Only one of the bases can swing, and at the same time, under the pressure of the springing, the second head (41) can springing, that is, the locking tongue (40) can move backward.

For example, when opening the door, if the outer side of the first body (411) contacts the door lock, the second body (43) will move backwards, and at the same time, the first body (411) and the second body (412) Swing at the same angle, so that the outer side and inner side of the first split body (411) and the second split body (412) both contact the door latch, so that the second head (41) squeezes into the main mortise lock (10) so that the latch (40) is ejected into the interior.

Therefore, each sub-body of the second head (41) includes: a second support block (414), which is carried on the upper and lower surfaces of each sub-body along the rear outer edge of the second hinge pin (45). Protruding, when the second head (41) is ejected, it contacts the side wall end (11) of the mortise lock main part (10).

When the first head (31) springs in, the swinging split body swings with the end of the second support block (414) of the side wall end (11) of the mortise lock main component (10) as a support point. When the two heads (41) are ejected, the end of the second support block (414) of the swinging split body contacts the side wall end (11) of the main mortise lock (10), and at the same time, the corresponding split body returns to the position before the swinging. Original location.

That is, the structure of this second support block (414) corresponding to the first support block (314) of the sub-lock (30) has the same specific function as the aforementioned first support block (314), however, the sub-lock When the first head (31) of (30) is ejected, it returns to the neutral position through the first support block (314). On the contrary, when the second head (41) of the lock tongue (40) is ejected, With two supporting blocks (414), each split body will return to the crossed position, which is different from the above.

At this time, the first support block (314) is based on the neutral position of the first head (31), and both ends contact the side wall end (11). The position shall prevail, and its two ends contact the side wall end (11).

Therefore, for the swing reset and stable support of each split body, both ends of the second support block (414) have the same plane as the side wall end (11), and are bent and connected to the outside of the support platform (415), and This support table (415) is also applicable to the first support block (314).

Next, the operator ( 50 ) for popping in and out of the latch ( 20 ) will be described.

The manipulator (50) includes an operating member (51) that drives the door bolt (20). The operating member (51) is based on FIG. 1 and rotates clockwise to eject the door bolt (20) into the side. Inside the wall end (11).

That is, the pusher (25) on the rear side of the latch (20) can be pressed on one side of the operating member (51), and when the operating member (51) rotates clockwise, the operating member ( 51) Push the pusher (25) to move the pusher (25) backwards to achieve the springing of the door bolt.

At this time, the operating member ( 51 ) can move according to the rotation of the separator ( 60 ) described later (when the escape function is used), but this is only limited to the escape function. Manual key or fingerprint recognition, password input, etc., the drive motor (512) can be unlocked.

To this end, the operating member (51) has a handle connecting hole (511) that can be connected to a manual key or a handle, which is provided for manually rotating the operating member (51), and when the external unlocking is performed, the driver is driven after identification. The motor (512) and the first gear (514) provided on the motor (512) mesh with the first gear (514), so that the second gear (515) connected to the operating member (51) ) drives the operating member (51) to rotate.

To this end, the operating member (51) is provided with a blocking block (517), and the second gear (515) is provided with a driving hole (515a) into which the blocking block (517) is inserted. When (515) rotates, the end of the driving hole (515a) pushes the blocking block (517) and rotates.

Therefore, in order to make the door bolt (20) spring into the main part of the mortise lock (10) to have a restoring force, the door bolt (20) also has a torsion spring (15), according to the door bolt (20) to return to In the original position, the rotating operating member (51) will also return to the original position.

The core indoor handle escape function of the present invention will be described in detail below.

First of all, the escape function refers to the function that in an emergency, when the indoor handle is turned, the door bolt (20) and the lock tongue (40) are linked and ejected so that the user can easily open the door. The handle can open the door, which can easily realize the escape function.

To this end, the present invention further includes a separator (60), the separator (60) comprising a handle shaft (61), an escape rotor (63) and a bolt rotor (65) provided on the handle shaft (61) .

First, the separator (60) is connected to the inner handle, including the escape rotor (63) and the latch rotor (65), which can be inserted into the separator (60).

The escape rotor (63) has a pressing block (631) protruding to one side. When the separator (60) rotates, the pressing block (631) also rotates together, which can drive the operating member (51) Rotate.

In more detail, in order to drive the operating member (51) through the rotation of the separator (60), the operating device (50) also has a first linkage gear (53) and a second linkage gear (54).

The first linkage gear (53) and the second linkage gear (54) are arranged above the separator (60), and they can be meshed and driven, the first linkage gear (53) and the second linkage gear (54) ) are respectively provided with a first handle (531) and a second handle (541), and the second pressure block (631) pushes the first handle (531) or the second handle.

That is, a pressing block (631) is arranged between the first handle (531) and the second handle (541).

Therefore, there is a protruding rod (533) on the end of the first interlocking gear (53) that rotates the operating member (51). Therefore, when the first interlocking gear (53) rotates clockwise, The protruding rod (533) pushes the lower left part of the operating member (51), so that the operating member (51) rotates in a clockwise direction to realize the springing of the door bolt.

That is, if the bolt (20) is to spring in, the first interlocking gear (53) must rotate clockwise. After the first interlocking gear (53) and the second interlocking gear (54) of the present invention are engaged, No matter how the separator (60) rotates, the first interlocking gear (53) is always rotated clockwise.

In more detail, if the separator (60) rotates in the counterclockwise direction, the pressing block (631) pushes the first handle (531) in the clockwise direction, thus, the first linkage gear (53) Rotate clockwise,

When the separator (60) is pushed in the clockwise direction, the pressing block (631) makes the second handle (541) rotate in the counterclockwise direction, and at this time, the second handle (541) rotates in the counterclockwise direction. The meshed first linkage gear (53) naturally rotates clockwise according to the meshing structure.

In addition, preferably, in order to make the first linkage gear (53) and the second linkage gear (54) have restoring force, the first elastic member (56) is connected to the first linkage gear (53) and the second linkage gear (54) on.

Therefore, when the user needs to open the door, the door can be opened only by rotating the separator (60), thereby improving the convenience of use.

Therefore, the present invention is characterized in that it further comprises a lock (70), which prevents the lock tongue (40) from springing forward when the door is locked and the sub-lock (30) is springing in.

In more detail, the locking device (70) can link the first body (33) of the sub-lock (30) and the second body (43) of the bolt (40), including the locking body (71), and The locking body (71) includes a through hole (711) penetrating through the first body (33) and an ejection opening (713) into which the second body (43) is ejected.

In more detail, the first body (33) has an inclined member (331) that descends forward, and a through hole (711) penetrating the inclined member (331) is provided on the locking body (71) .

To sum up, when the sub-lock (30) springs in, the first body (33) moves backward, and at this time, the first body (33) can pass through the locking body (33). 71) through holes (711) provided on.

Therefore, as the locking body (71) descends, the springing of the locking tongue (40) is restricted. For this reason, preferably, a third elastic body (73) is provided above the locking body (71). , the locking body (71) can be moved downward through elasticity.

In the closed state of the door, the sub-lock (30) springs into the interior of the main mortise lock (10), at this time, the inclined member (331) is located behind the through hole (711), so The locking body (71) descends to limit the springing of the locking tongue (40),

When the door is opened, the sub-lock (30) moves forward, at this time, the inclined member (331) of the first body (33) moves to the front end of the through hole (711), and the through hole The upper surface of ( 711 ) rises along the inclined member ( 331 ), therefore, generally speaking, the locking body ( 71 ) is lifted. That is, through the locking body (71) rising in this way, the device restricting the springing of the locking tongue (40) can be eliminated, and the locking tongue (40) can be caused to spring into the interior of the mortise lock main part (10).

Therefore, for the device for the locking body (71) to prevent the locking tongue (40) from being ejected, first of all, there is a second body (43) under the locking body (71) that can spring into the locking tongue (43). Bullet import (713).

At this time, there is a locking step (431) on the second body (43), and when the locking body (71) descends, the upper end of the bomb inlet (713) is in close contact with the second body (43). Above, at this time, the locking step (413) is stuck on the spring inlet (713), so that it cannot spring in, thereby preventing the bolt from springing in.

On the contrary, when the locking body (71) rises, the upper surface of the ejection opening (713) is away from the second body (43), and according to this distance, the locking step (413) can be ensured Enter the space of the ejection inlet (713) to form a structure that allows the locking tongue (40) to eject.

Therefore, before the door bolt (20) is moved backward (unlocked), when the lock tongue (40) springs in, and the door is unreasonably opened, problems such as serious deadlock of the door bolt may occur.

Therefore, before the rearward movement of the door bolt (20) is completed, in order to prevent the lock tongue (40) from bouncing in, some time difference should be set. Through this time difference, the locking body (71) can rise longer than the door bolt. (20) The ejection time is slower, and the present invention can solve these problems through the lock releaser (80).

First, in order to allow the sub-lock (30) and the bolt (40) to spring forward, the lock releaser (80) lifts the descending locking body (71), and this action is consistent with the separator (60). ) action to contact.

To this end, the lock releaser (80) includes a first linkage (81) and a second linkage (83) that are linked with the movement of the latch rotating body (65) of the separator (60). The first linkage (81) and the second linkage (83) are engaged and rotated through gears.

In addition, one side of the first linkage member (81) and one side of the second linkage member (83) are respectively provided with a first clamping member (811) and a second clamping member (831). These first clamping members (811) ) and the second clamping member (831), there is a clamping rod (651) of the bolt rotating body (65).

In addition, the other side of the first linkage member (81) is provided with a rising guide member (813), and the rising guide member (813) is inserted into the through hole (715) of the locking body (71).

Therefore, when the first linking member (81) rotates clockwise, the rising guide member (813) pushes the upper part of the through hole (715) upward, at this time, the locking body (71) rises, thereby allowing The rearward movement of the sub-lock (30) and the deadbolt (40).

Therefore, the separator (60) of the present invention can be rotated in both directions, for this reason, the first linkage (81) and the second linkage (83) of the locked releaser (80) are also geared. Structure.

That is, the purpose of the present invention is to rotate the first linkage (81) in the clockwise direction, and when the separator (60) rotates in the counterclockwise direction, the rotation of the latch rotating body (65) on the separator (60) The clamping rod (651) pushes the first clamping member (811) of the first linkage member (81), whereby the first linkage member (81) can move in the counterclockwise direction,

When the separator (60) rotates in the counterclockwise direction, the clamping rod (651) pushes the second clamping member (831) to rotate the second linkage member (83) in the counterclockwise direction, and The first linkage (81) engaged with it rotates clockwise again.

In the present invention, in order to prevent the locking phenomenon of the door bolt (20), some time difference needs to be set. The middle part of the first clip (811) or the second clip (831), and the first clip (653) between the clip rod (651) and the separator (60) is inserted 811) or the end of the second clip (831).

For this structure, the separator (60) is provided with a pair of bolt rotating bodies (65), and a rod-shaped clamping rod (651) protruding from one side of the bolt rotating body (65) and connecting the ends of the protruding parts ), and the escape rotating body (63) forms a triple structure between the pair of latch rotating bodies (65).

That is, the clamping rod (651) pushes the first clamping member (811) (taking the first clamping member (811) as an example for illustration, the second clamping member (831) is the same as the first clamping member (811)) When the middle area of The rising start time of (71) is slower than the unlocking start time of the door bolt (20), thereby preventing the locking phenomenon on the door bolt (20).

Therefore, preferably, the first linkage member (81) and the second linkage member (83) are further provided with a second elastic member (85) for restoring these to their original positions, so as to improve the convenience of use.

Above, with reference to the drawings of the present invention, the door lock mortise lock with a specific form and structure has been described, but those of ordinary skill in the technical field of the present invention can make various deformations and changes within the technical idea and scope of the present invention, These deformations and changes belong to the protection scope of the present invention.
