A partial enlarged view of the core, FIG. 4 is a diagram showing a state in which the latch lever rotates to restrict and allow the rotation of the latch pin in the door lock mortise of the embodiment of the present invention, and FIG. 5 is a view showing the embodiment of the present invention. Figures 6 to 10 are diagrams showing the coupling relationship of the first handle block, the second handle block, and the third handle block in the door lock mortise, and FIGS. 6 to 10 are performed by a motor in the door lock mortise according to the embodiment of the present invention. Figures 11 to 15 are diagrams showing the unlocking operations of the fixing bolt and the latch pin by the operation of the push-pull handle in the door lock mortise according to the embodiment of the present invention. 16 to 20 are diagrams showing the unlocking action of the fixing bolt and the latch pin using the key in the door lock mortise of the embodiment of the present invention.

As shown in FIGS. 1 to 20 , the door lock mortise of the embodiment of the present invention includes a housing 10 , a main body front 20 , a latch pin 100 , a first gear box 220 and a second gear box 140 , a fixing bolt 200 , The sub-lock 300 , the first handle block 910 , the second handle block 920 , the third handle block 930 and the PCB 330 .

The housing 10 protects each structure of the door lock mortise and is attached to the door. In addition, a key hole for a user to insert a key in order to open a door outdoors, and a key input part or a card contact part for releasing the latch pin 100 and the fixing bolt 200 are mounted on the outdoor side of the casing 10 .

In addition, a push-pull handle (not shown) is provided on the indoor side of the casing 10 for the user to release the latch pin 100 and the fixing bolt 200 indoors, and the force of pushing or pulling the push-pull handle (not shown) is converted. A rotating shaft (not shown) for rotating force is formed inside the casing 10. When the push-pull handle (not shown) is pushed or pulled, the rotating shaft (not shown) converts the thrust into a rotating force, thereby The 1st handle block 910 and the 3rd handle block 930 mentioned later are rotated. Such conversion of the rotation axis (not shown) is a well-known technique, and therefore detailed description is omitted.

The front part 20 of the main body is formed so as to be opposite to the side surface of the housing 10 , that is, the locking plate (not shown), and is formed with an introduction hole for the latch pin 100 , the fixing bolt 200 and the sub-lock 300 to enter and exit.

The latch pin 100 is used to prevent the door from being opened by itself to keep the closed state, and is formed protrudingly for linear introduction of the latch pin 100 while abutting against the door frame when the door is closed from the open state.

As shown in FIG. 3 and FIG. 4 , such a latch pin 100 is formed with a stopper protrusion 110 which is elastically supported by a spring 130 formed on the rear side, and abuts against the inner side surface of the front part 20 of the main body on one of the two side surfaces. Then, the latch pin 100 is prevented from being disengaged to the outside of the front part 20 of the main body;

As shown in FIG. 4( a ), the pressing portion 730 is pushed away by the elastic force of the spring 740 formed in the pressing portion 730 of the latch lever 700 , and the latch lever 700 is shown in the drawing with the rotation shaft 701 as the center. is rotated in the clockwise direction, whereby the rotation restricting portion 720 of the latch lever 700 is introduced through the groove 151 of the frame 150, when the lower end face of the rotation restricting portion 720 is in contact with the upper end face of the protruding portion 120 of the latch pin 100 , the rotation of the latch pin 100 is restricted. As shown in FIG. 4( b ), the pressing portion 730 of the latch lever 700 presses the spring 740 by an external force. Rotating in the counterclockwise direction, when the rotation restricting portion 720 of the latch lever 700 is disengaged from the protruding portion 120 of the latch pin 100 , the latch pin 100 is allowed to rotate. At this time, in the present invention, a reinforcing material is formed between the upper end surface and the lower end surface of the rotation restricting portion 720 of the latch lever 700 to prevent the rotation restricting portion 720 from being deformed or damaged due to repeated use. Specifically, when an empty space is formed between the upper end surface and the lower end surface of the rotation restricting portion 720, the rotation restricting portion 720 continuously receives force through the protrusion 120 of the latch pin 100 and is deformed and twisted, or when In severe cases, breakage may occur, but in the present invention, a reinforcing material is formed between the upper end surface and the lower end surface of the rotation restricting portion 720 to increase the strength of the rotation restricting portion 720, even if it is damaged by the protrusion 120 of the latch pin 100. Continue to apply force to prevent deformation or breakage.

In addition, the pressing portion 730 of the latch lever 700 is integrally formed with the pressing protrusion 146 of the driven gear 143 that is rotated by receiving a rotational force by a second motor 141 and a second driving gear 142 to be described later, forward and rearward. As a result of the movement, the pressing portion 730 of the latch lever 700 moves forward by the rotation of the pressing protrusion 146 , and the latch lever 700 rotates around the rotation shaft 701 , so that the rotation restricting portion 720 of the latch lever 700 is released from the collision. The protrusion 120 of the spring pin 100 is disengaged, thereby allowing the snap pin 100 to rotate. A specific description of this will be described later.

The fixing bolt 200 is a structure in which the door is locked or unlocked by being drawn out and introduced through the introduction hole of the front part 20 of the main body, and a slider 201 is integrally formed at the rear of the fixing bolt 200. The first fixing bolt pulling rod 210 and the second fixing bolt pulling rod 211 are linearly moved forward and backward to draw the fixing bolt 200 in and out from the main body front part 20 .

The distal end of the second anchor drawbar 211 is inserted into the long hole 202 formed in the slider 201, and the first anchor drawbar 210 abuts on an emergency lever 400 to be described later.

Accordingly, when the first anchor drawbar 210 and the second anchor drawbar 211 receive the driving force of the first motor 221 to be described later and rotate clockwise or counterclockwise in the drawing, the second anchor draws The distal end of the rod 211 moves to the upper end or the lower end along the long hole 202 of the slider 201 to push or pull the slider 201 forward, thereby leading or introducing the fixing bolt 200 . In addition, when the emergency lever 400 described later comes into contact with the first handle block 910 and the third handle block 930 that are rotated by the user's push-pull handle (not shown) operation, or the second handle block 920 that is rotated by the key operation, During the rotation, the first fixing bolt drawbar 210 abutting on the emergency lever 400 rotates, and at the same time, the second fixing bolt drawbar 211 rotates so that the end of the second bolt drawbar 211 follows the long hole 202 of the slider 201 Then, it moves to the lower end, so that the fixing pin 200 is introduced. The specific description of the pull-in and pull-out operations of the fixing bolt 200 will be described later.

On the other hand, a torsion spring 230 is coupled to one side of the second bolt draw bar 211 , and the torsion spring 230 acts as an elastic force when compressed, like a general spring, so that the second bolt draw bar 211 acts as an elastic force. In the initial stage of rotation, the torsion spring 230 is compressed in the opposite direction to the direction in which the elastic force of the torsion spring 230 acts and rotates. Therefore, the second bolt drawbar 211 is gradually rotated by the elastic force. During the procedure, when the second bolt drawbar 211 rotates by a certain angle, it rotates in the direction in which the elastic force of the torsion spring 230 acts, that is, the direction in which the torsion spring 230 extends. Therefore, the torsion spring 230 immediately expands, and the second bolt drawbar 211 also rotates. Correspondingly, there is a sharp rotation, whereby the fixing bolt 200 is immediately introduced. That is, when the fixing bolt 200 is introduced by the user's push-pull handle (not shown) operation or the operation of the key, it is gradually introduced in the initial stage, and then immediately after being introduced to a certain distance, the entire area of the fixing bolt 200 passes through the front part of the main body 20 introduction holes were introduced.

The sub-lock 300 is a structure for detecting the closed and open state of the door by being drawn in and out from the front part 20 of the main body, and there is no space for introducing the sub-lock 300 in the door frame. Therefore, when the door is closed, the sub-lock 300 is drawn into the front part of the main body. In the state of 20, when the door is opened, it is drawn out from the front part 20 of the main body by the elastic force of the spring 301 formed in the rear. In addition, on the side surface of the sub-lock 300, a pressing protrusion 302 is formed that presses a protrusion 602 of a draw bar 600 to be described later and lifts a stopper protrusion 601 of the draw bar 600. A specific description of this will be described later.

A device for automatically driving the first driving gear 222 and the second driving gear 142 to control the fixing bolt 200 and the latch pin 100 is provided between the fixing bolt 200 and the sub-lock 300 by checking the open and closed states of the door.

That is, the PCB 800 is provided with an opening detection sensor 810, a closing detection sensor 820 and a sub-lock detection sensor 830, and the slider 201 and the sub-lock 300 are respectively formed with detection parts 203 and 303. When the slider 201 moves forward When the fixing bolt 200 is drawn out, the detection part 203 is located on the closing detection sensor 820, and the closing detection sensor 820 detects this and determines that the fixing bolt 200 is drawn out. When the slider 201 moves backward, the fixing bolt 200 is removed. At the time of introduction, the detection part 203 is located on the opening detection sensor 810, and the opening detection sensor 810 detects this, and it is determined that the fixing bolt 200 has been introduced.

In addition, when the sub-lock 300 is introduced and the detection portion 303 is separated from the sub-lock detection sensor 830, the sub-lock detection sensor 830 determines that the door is closed, and when the sub-lock 300 is drawn out, the detection portion 303 and the sub-lock detection sensor 830 determine that the door is closed. When the detector 830 is connected, the sub-lock detection sensor 830 determines that the door is opened.

The first gear box 220 and the second gear box 140 respectively include a first motor 221 and a second motor 141 and a first driving gear 222 and a second driving gear 142 , and receive the rotational force of the first motor 221 and the second motor 141 to generate The rotating first driving gear 222 and the second driving gear 142 respectively mesh with the driven gear 143 on which the pin pull gear 213 and the pressing protrusion 146 are integrally formed, and rotate together. As a result, when the first drive gear 222 and the bolt pulling gear 213 are rotated by the driving of the first motor 221 , the first bolt pulling rod 210 and the second bolt pulling rod, which are integrally formed with the bolt pulling gear 213 , are rotated. 211 is rotated together, whereby the distal end of the second fixing bolt pulling rod 211 moves up and down from the long hole 202 of the slider 201, and the fixing bolt 200 integrally formed with the slider 201 and the slider 201 is introduced from the front part 20 of the main body and lead out.

In addition, when the second driving gear 142 and the driven gear 143 are rotated by the driving of the second motor 141, the pressing protrusion 146 formed integrally with the driven gear 143 rotates together, and thereby the latch lever 700 is rotated. The pressing portion 730 moves forward and backward to rotate the latch lever 700 around the rotation shaft 701, and the rotation restricting portion 720 of the latch lever 700 pressurizes or releases the pressure on the protrusion 120 of the latch pin 100 by This limits or allows rotation of the latch pin 100 . At this time, the cam 144 is integrally formed on the driven gear 143, and the restricting portions 145 are respectively formed at both ends of the cam 144 so as to be spaced apart from each other. The rotation radius of the movable gear 143 and the pressing protrusion 146 is determined.

As shown in FIG. 5 , the first handle block 910 , the second handle block 920 and the third handle block 930 are the first handle block 910 and the third handle block 930 are integrally connected by a coupling pin 940 and rotate simultaneously, and the second handle block The 920 is inserted between the first handle block 910 and the third handle block 930 to be coupled, and the second handle block 9201 is formed so as not to contact the second handle block 920 when the handle block 910 and the third handle block 930 rotate. A lock unit 932 is formed in the third handle block 930 for the guide groove 922 that rotates independently. The first handle block 910, the second handle block 920, and the third handle block 930 are concentric circles in the order of the first handle block 910, the second handle block 920, and the third handle block 930 from the position close to the outdoor side. For coupling, the second handle block 920 is formed with a polygonal second coupling hole 921 for coupling with the outdoor conversion rotating shaft connected to the key when the user uses the key, and the third handle block 930 is formed with a coupling with indoor conversion. The third coupling hole 931 of the polygonal shape of the rotating shaft is formed in the first handle block 910 with the first coupling hole 911 having the same shape and size as the third coupling hole 931 and not connected to any member.

The above-mentioned indoor conversion rotating shaft is the first one that is integrally combined with the third handle block 930 by converting the force of the push-pull handle pressing or pulling the door lock mortise into the rotational force of the third handle block 930 through a push-pull operation. The handle block 910 rotates, and the outdoor conversion rotating shaft is connected to the key and rotates together with the rotation of the key.

The outdoor conversion rotary shaft is attached to the second coupling hole 921, the indoor conversion rotary shaft is attached to the third coupling hole 931, and the key is connected to the outdoor conversion rotary shaft. Therefore, when the key is inserted from the outside and rotated, only the outdoor conversion rotary shaft and the second handle block 920 coupled to the outdoor conversion rotary shaft are rotated. When the push-pull handle (not shown) is pushed or pulled, the indoor conversion rotary shaft and the outdoor conversion rotary shaft are rotated. The third handle block 930 coupled to the indoor conversion rotating shaft and the first handle block 910 integrally coupled with the third handle block 930 rotate together.

With such a structure, when the user pushes or pulls the push-pull handle (not shown) indoors to rotate the indoor conversion shaft, the second handle block 920 rotates the third handle block 930 in a fixed state. At this time, the third handle The block 930 is connected to the first handle block 910 and therefore rotates together. The third handle block 930 rotates clockwise in the drawing to rotate the emergency lever 400 in contact, and the emergency lever 400 that is rotated by the third handle block 930 The first anchor drawbar 210 is in contact with the first anchor drawbar 210 to rotate counterclockwise in the drawing.

As a result, the second bolt drawbar 211 integrally formed to rotate simultaneously with the first bolt drawbar 210 also rotates at the same time, so that the distal end of the second bolt drawbar 211 follows the long hole of the slider 201 . 202 to move downward, so that the fixing bolt 200 is introduced into the front part 20 of the main body, and then the emergency lever 400 is further rotated clockwise in the drawing to abut against the lower end stopper protrusion 710 of the latch lever 700 to make the latch The lever 700 rotates around the rotation shaft 701 to disengage the rotation restricting portion 720 from the protruding portion 120 of the latch pin 100 , thereby allowing the latch pin 100 to rotate. At this time, as shown in FIG. 2 , the emergency lever 400 is in contact with the first fixing bolt pulling lever 210 and is spaced apart from the lower end stopper protrusion 710 of the latch lever 700 by a certain distance. Therefore, after the introduction of the fixing bolt 200 is completed, The emergency lever 400 and the lower end stop protrusion 710 of the latch lever 700 come into contact, thereby realizing the unlocking of the latch pin 100. Elastic springs 410 and 740 are respectively formed on the emergency lever 400 and the latch lever 700, so that when the external force is removed , the emergency lever 400 and the latch lever 700 are automatically restored to their original positions by elastic force.

In addition, as the third handle block 930 rotates, the locking unit 932 integrally formed with the third handle block 930 also rotates in the clockwise direction in the drawing, from the stopper projection 601 of the draw bar 600 in the drawing. right to left.

In addition, as shown in FIG. 14 , the drawbar 600 moves up and down the left and right protrusions 602 and the stopper protrusions 601 opposite to each other with the central hinge shaft 604 as the center like a seesaw (that is, when the protrusions 602 rise, The stopper protrusion 601 descends, and when the protrusion 602 descends, the stopper protrusion 601 ascends), and a spring 603 is formed at the lower end of the protrusion 602. Therefore, when no external force is applied, the protrusion 602 always maintains the rising state, and the stopper protrusion 601 is kept in the lowered state, the right side of the stop protrusion 601 of the draw bar 600 is formed in a gentle curve shape in the drawing, and the left side of the stop protrusion 601 of the draw bar 600 is formed in a straight shape in the drawing. When the stopper protrusion 601 is lowered, the locking unit 510 can move from the right side to the left side of the stopper protrusion 601 in the drawing, but cannot move from the left side to the right side of the stopper protrusion 601 in the drawing, and only the stopper protrusion 601 rises before it can be moved.

With the above-mentioned structure, the third handle block 930 is rotated according to the operation of the push-pull handle (not shown), and the lock unit 932 is moved from the right side to the left side of the stopper protrusion 601 of the drawbar 600 in the drawing. Even if the emergency lever 400 pushes the third handle block 930 away by the elastic force of the spring 410, the locking unit 932 is stopped by the left side of the stopper projection 601 and is in a locked state that cannot be passed over. The lock unit 932 that stops on the left side of the stopper projection 601 , the third handle block 930 integrally formed with the lock unit 932 , the emergency lever 400 , the first bolt draw lever 210 and the latch lever 700 abutting against the emergency lever 400 The rotations of the pins 200 are all restricted, and the introduced state of the fixing bolt 200 and the unlocked state of the latch pin 100 are continued.

Then, when the sub-lock 300 is pulled out, the pressing protrusion 302 of the sub-lock 300 presses the lower end of the protruding portion 602 of the drawbar 600 to lower it, whereby the stopper protrusion 601 on the opposite side rises to release the unlocking unit 932 In the stop state, the third handle block 930 is in a rotatable state, and the emergency lever 400 is rotated by the elastic force of the spring 410 to abut against the third handle block 930 to rotate the third handle block 930, thereby The locking unit 932 goes from the left side of the stop protrusion 601 to the right side in the drawing.

In addition, as the emergency lever 400 is rotated counterclockwise in the drawing by the spring 410 and returns to the original position, the emergency lever 400 and the first bolt draw bar 210 are separated from each other, and the first bolt draw bar 210 and the first bolt draw bar 210 are separated from each other. 2. The fixing bolt pulling lever 211 is rotatable so that the fixing bolt 200 can be drawn out by the driving of the first motor 221, the emergency lever 400 and the lower end stopper projection 710 of the latch lever 700 are separated from each other, whereby the latch lever 700 It is rotatable so that by the elastic force of the spring 740 formed in the pressing portion 730 of the latch lever 700, the latch lever 700 is rotated clockwise in the drawing so that the rotation restricting portion 720 of the latch lever 700 passes through the frame 150 The side grooves 151 of the latch pins 100 are introduced, thereby pressing the protrusions 120 of the latch pins 100 to restrict the rotation of the latch pins 100 .

On the other hand, when the user inserts the key outdoors and rotates, the first handle block 910 and the third handle block 930 are fixed, and only the second handle block 205 to which the outdoor conversion rotating shaft is coupled rotates together with the key. At this time, in the present invention, according to the direction in which the user rotates the key, the second handle block 920 is rotated clockwise or counterclockwise in the drawing. That is, when the user rotates the key clockwise or counterclockwise according to convenience, the second handle block 920 rotates clockwise or counterclockwise to rotate the emergency lever 400 .

According to such a configuration, when the user inserts the key outdoors and rotates, the first handle block 910 and the third handle block 930 are in a fixed state, and only the second handle block 920 rotates clockwise or counterclockwise in the drawing. Then, the abutting emergency lever 400 is rotated, and the emergency lever 400 rotated by the second handle block 920 comes into contact with the first anchor drawbar 210 to rotate the first anchor drawbar 210 counterclockwise in the drawing. .

As a result, the second bolt drawbar 211 integrally formed with the first bolt drawbar 210 rotates at the same time and moves to the lower end along the long hole 202 of the slider 201, thereby introducing the bolt 200 into the main body The front part 20 and then the emergency lever 400 are further rotated in the clockwise direction in the drawing, come into contact with the lower end stopper projection 710 of the latch lever 700, and rotate the latch lever 700 around the rotation axis 701 to rotate the rotation restricting portion 720 is disengaged from the protrusion 120 of the latch pin 100, thereby allowing the latch pin 100 to rotate. At this time, as shown in FIG. 2 , the emergency lever 400 is in contact with the first fixing bolt drawbar 210 and is spaced from the lower end stopper projection 710 of the latch lever 700 by a certain distance. Therefore, when the introduction of the fixing bolt 200 is completed, the emergency The lower end stop protrusion 710 of the lever 400 and the latch lever 700 come into contact to realize the unlocking of the latch pin 100. Elastic springs 410 and 740 are respectively formed on the emergency lever 400 and the latch lever 700. When the external force is removed, the emergency lever 400 And the latch lever 700 automatically returns to the original position by elastic force.

After that, when the user rotates the key to the original position again, the second handle block 920 also rotates to return to the original position at the same time, so as to be away from the emergency lever 400 , so that the emergency lever 400 is also re-positioned by the elastic force of the spring 410 . Rotate counterclockwise on the drawing to return to the original position.

In addition, when the emergency lever 400 is rotated counterclockwise in the drawing by the spring 410 to return to the original position, the emergency lever 400 and the first bolt drawbar 210 are separated from each other, whereby the first bolt drawbar 210 and The second fixing bolt pulling lever 211 rotates to form a state in which the fixing bolt 200 is drawn out by the driving of the first motor 221 , and the emergency lever 400 and the lower end stopper projection 710 of the latch lever 700 are separated from each other so that the latch lever 700 can be rotated , so that the latch lever 700 is rotated clockwise in the drawing by the elastic force of the spring 740 formed in the pressing portion 730 of the latch lever 700 , so that the rotation restricting portion 720 of the latch lever 700 passes through the frame 150 The side groove 151 of the latch pin 100 is introduced to press the protrusion 120 of the latch pin 100 , thereby restricting the rotation of the latch pin 100 .

The door lock mortise of the embodiment of the present invention described above can be further embodied by the description of the following operation program.

6 to 10, the operation sequence of the door lock mortise when the door is opened from the outside through the key input unit and the card contact unit will be described in detail.

As shown in FIG. 6 , when the door is closed and the latch 200 is drawn out, in a state where the latch pin 100 is locked and the rotation of the latch pin 100 is restricted, a number is input through the key input portion or a card is brought into contact with the card contact portion in order to open the door from the outside. 7 , the first motor 221 is first driven to rotate the first drive gear 222 and the bolt pulling gear 213, whereby the first bolt pulling rod 210 and the first bolt pulling rod 210 and the first bolt pulling rod 210 integrally formed with the bolt pulling gear 213 are rotated. 2. The fixing bolt pulling rod 211 is rotated together in the counterclockwise direction in the drawing, so that the end of the second fixing bolt pulling rod 211 moves from the long hole 202 of the slider 201 to the lower end, so that the sliding block 201 and its integral The formed fixing bolt 200 is introduced into the front part 20 of the main body, thereby unlocking the fixing bolt 200 .

With the introduction of the fixing bolt 200, the detection part 203 of the fixing bolt 200 is located on the opening detection sensor 810. When the opening detection sensor 810 detects the release of the fixing bolt 200, the second motor 141 is driven, the second driving gear 142 and the As the driven gear 143 rotates, the pressing protrusion 146 integrally formed with the driven gear 143 rotates together with the pressing portion 730 of the latch lever 700 to move forward, so that the latch lever 700 rotates around the axis of rotation. 701 is rotated in the counterclockwise direction in the drawing, whereby the rotation restricting portion 720 of the latch lever 700 is disengaged from the protruding portion 120 of the latch pin 100 to release the pressurization, thereby allowing the latch pin 100 to rotate.

After that, as shown in FIG. 8 , when the user pulls the door to open the door outdoors, the latch plate (not shown) of the door pushes out the latch pin 100 by the user's pulling force, so that the latch 100 can be rotated. The pin 100 is rotated counterclockwise and introduced into the interior of the door lock mortise.

As shown in FIG. 9 , when the door is fully opened and the user's pulling force is released, the latch pin 100 and the sub-lock 300 are drawn out from the front part 20 of the main body by the elastic restoring force of the respective springs 130 and 301, whereby the sub-lock The detection part 303 of the 300 is in contact with the sub-lock detection sensor 830, and when the sub-lock detection sensor 830 detects that the door is opened, first the second motor 141 is reversed to cause the second drive gear 142 and the driven gear 143 Inversely, the pressing protrusion 146 is rotated counterclockwise in the drawing to return to the original position, thereby releasing the force applied to the pressing portion 730 of the latch lever 700 by the pressing protrusion 146, thereby increasing the The pressing portion 730 is moved rearward by the elastic restoring force of the spring 740, so that the latch lever 700 rotates clockwise in the drawing, and the rotation restricting portion 720 pressurizes the protrusion 120 of the latch pin 100 to restrict the latch lever 720. 100 spins.

After that, when the door is closed again, the latch pin 100 applies a force to the inclined surface opposite to when the door is opened. That is, the latch plate of the door collides with the inclined surface of the latch pin 100 to apply a force pushing the latch pin 100 into the door lock mortise, whereby the spring 130 is pushed back, and the latch pin 100 does not rotate and Enter the interior of the housing 10 straightly. When the door is fully closed, by the force of the spring 130, the latch pin 100 protrudes back into the slot of the door frame.

In addition, the sub-lock 300 is introduced into the front part 20 of the main body, whereby the detection part 303 of the sub-lock 300 is separated from the sub-lock detection sensor 830. When the sub-lock detection sensor 830 detects that the door is closed, as shown in FIG. 10 As shown, the first motor 221 is first driven to rotate the first drive gear 222 and the bolt pulling gear 213, whereby the first bolt pulling rod 210 and the second bolt pulling rod are formed integrally with the bolt pulling gear 213. 211 are rotated together in the clockwise direction in the drawing, whereby the end of the second fixing bolt drawbar 211 moves upward in the elongated hole 202 of the slider 201, so that the slider 201 and the fixing bolt formed integrally therewith are moved to the upper end. 200 is drawn out from the front part 20 of the main body, whereby the door is in a locked state.

11 to 15 , the procedure for operating the door lock mortise when the push-pull handle (not shown) is pushed or pulled in order to open the door indoors will be described.

As shown in FIG. 11 , in order to open the door indoors, the push-pull handle (not shown) of the door is pushed or When pulling, as shown in FIG. 12 , the third handle block 930 rotates clockwise in the drawing to rotate the abutting emergency lever 400 , and the emergency lever 400 rotated by the third handle block 930 and the first fixing bolt The draw bar 210 abuts and rotates the first anchor draw bar 210 counterclockwise in the drawing.

As a result, the second bolt drawbar 211 integrally formed so as to rotate simultaneously with the first bolt drawbar 210 rotates simultaneously, so that the distal end of the second bolt drawbar 211 extends along the long hole 202 of the slider 201 . The lower end is moved to introduce the fixing bolt 200 into the front part 20 of the main body, and then the emergency lever 400 is further rotated in the clockwise direction in the drawing to abut against the lower end stop protrusion 710 of the latch lever 700, thereby locking the latch The lever 700 is rotated counterclockwise in the drawing with the rotation shaft 701 as the center to disengage the rotation restricting portion 720 from the protruding portion 120 of the latch pin 100 , thereby allowing the latch pin 100 to rotate. At this time, as shown in FIG. 11 , the emergency lever 400 is in contact with the first fixing bolt drawbar 210 and is spaced apart from the lower end stopper projection 710 of the latch lever 700 by a certain distance. Therefore, after the introduction of the fixing bolt 200 is completed, the emergency The lever 400 and the lower end stop protrusion 710 of the latch lever 700 come into contact to realize the unlocking of the latch pin 100 .

In addition, as the third handle block 930 rotates, the locking unit 932 integrally formed with the third handle block 930 also rotates clockwise in the drawing, from the right side of the stopper projection 601 of the drawbar 600 in the drawing. Move to the left.

Thus, in the state where the locking unit 932 moves from the right side to the left side of the stopper protrusion 601 of the drawbar 600 in the drawing, even if the elastic force of the spring 410 causes the emergency lever 400 to push the third handle block 930 away, the locking unit 932 is stopped by the left side of the stopper projection 601 and is in a locked state that cannot be passed over. In such a locked state, the first lock unit 932 formed integrally with the lock unit 932 is restricted by the lock unit 932 stopped on the left side of the stopper projection 601. 3. The rotation of the handle block 930, the emergency lever 400, the first fixing bolt drawbar 210 and the latching lever 700 abutting against the emergency lever 400 keep the lead-in state of the fixing bolt 200 and the unlocking state of the latch pin 100 continuously, and then as follows: As shown in FIG. 13 , the latch plate (not shown) of the door pushes the latch pin 100 away by the user's pushing force, so that the rotatable latch pin 100 rotates counterclockwise and is introduced into the door lock mortise internal.

As shown in FIG. 14 , when the door is fully opened, the sub-lock 300 is drawn out from the front part 20 of the main body by the elastic restoring force of the spring 301, and the pressing protrusion 302 of the sub-lock 300 pushes the protrusion 602 of the pulling rod 600 to the horizontal direction By pushing and descending, the stopper projection 601 on the opposite side rises to release the stopper state of the unlocking unit 932, whereby the third handle block 930 is brought into a rotatable state, and the emergency lever 400 is released by the elastic force of the spring 410. By rotating and abutting the third handle block 930 to rotate the third handle block 930 , the lock unit 932 goes over from the left side of the stopper protrusion 601 to the right side in the drawing.

In addition, as the emergency lever 400 is rotated counterclockwise in the drawing by the spring 410 to return to the original position, the emergency lever 400 and the first bolt drawbar 210 are separated from each other, whereby the first bolt drawbar 210 and the first bolt drawbar 210 are separated from each other. 2. The fixing bolt pulling lever 211 is rotatable so that the fixing bolt 200 can be drawn out by the driving of the first motor 221, the emergency lever 400 and the lower end stopper projection 710 of the latch lever 700 are separated from each other, whereby the latch lever 700 Rotation is possible so that the latch lever 700 is rotated clockwise in the drawing with the rotation shaft 701 as the center by the elastic force of the spring 740 formed in the pressing portion 730 of the latch lever 700, so that the latch lever 700 is rotated clockwise. The rotation restricting portion 720 pressurizes the protruding portion 120 of the latch pin 100 to restrict the rotation of the latch pin 100 .

After that, when the door is closed again, the latch pin 100 applies a force to the inclined surface opposite to when the door is opened. That is, the latch plate of the door collides with the inclined surface of the latch bolt 100, and the latch bolt 100 is applied with a force that pushes the inside of the door lock mortise, thereby pushing the spring 130 backward, and the latch bolt 100 does not rotate. In the case of linearly entering the interior of the housing 10 . When the door is fully closed, the latch pin 100 is re-protruded toward the slot of the door frame by the force of the spring 130 .

In addition, the sub-lock 300 is introduced into the front portion 20 of the main body, whereby the detection portion 303 of the sub-lock 300 is separated from the sub-lock detection sensor 830, whereby the sub-lock detection sensor 830 detects when the door is closed, such as As shown in FIG. 15 , first, when the first motor 221 is driven, the first drive gear 222 and the bolt pulling gear 213 are rotated, whereby the first bolt pulling rod 210 and the second bolt pulling rod 210 and the second bolt pulling rod 210 integrally formed with the bolt pulling gear 213 are rotated. The fixing bolt pulling rod 211 is rotated together in the clockwise direction in the drawing, so that the end of the second fixing bolt pulling rod 211 is moved to the upper end in the long hole 202 of the slider 201, thereby integrating the slider 201 with the same. The fixed bolt 200 formed in the ground is drawn out from the front part 20 of the main body, whereby the door is in a locked state.

16 to 20 , a description will be given of a procedure for operating the door lock mortise when the user inserts the key from the outdoors and rotates in order to open the door indoors.

As shown in FIG. 16 , when the door is closed, the latch 200 is drawn out to be in the locked state, and the rotation of the latch pin 100 is restricted, when the user inserts the key and rotates the key to open the door outdoors, as in As shown in FIG. 17 , the second handle block 920 rotates clockwise or counterclockwise in the drawing along the direction in which the user rotates the key, so that the abutting emergency lever 400 is rotated, and the second handle block 920 rotates The rotating emergency lever 400 is in contact with the first anchor drawbar 210 to rotate the first anchor drawbar 210 counterclockwise in the drawing.

As a result, the second bolt drawbar 211 integrally formed so as to rotate simultaneously with the first bolt drawbar 210 rotates at the same time, and the distal end of the second bolt drawbar 211 is moved along the elongated hole 202 of the slider 201 . The lower end is moved to introduce the fixing bolt 200 into the front part 20 of the main body, after which the emergency lever 400 is further rotated clockwise in the drawing to abut against the lower end stop protrusion 710 of the latch lever 700, thereby causing the latch The lever 700 rotates counterclockwise in the drawing with the rotation shaft 701 as the center, thereby disengaging the rotation restricting portion 720 from the protruding portion 120 of the latch pin 100 , thereby allowing the latch pin 100 to rotate. At this time, as shown in FIG. 16 , the emergency lever 400 is in contact with the first fixing bolt drawbar 210 and is spaced apart from the lower end stopper projection 710 of the latch lever 700 by a certain distance. Therefore, after the introduction of the fixing bolt 200 is completed, the emergency The lever 400 and the lower end stop protrusion 710 of the latch lever 700 come into contact to realize the unlocking of the latch pin 100 .

In the above-described state, the key is rotated until the user fully opens the door. Therefore, the second handle block 920 is also fixed in a rotated state, and is fixed to the emergency lever 400 and the first contact with the emergency lever 400. By restricting the rotation of the bolt pulling lever 210 and the latch lever 700, the introduced state of the fixing bolt 200 and the unlocked state of the latch bolt 100 are continued, and as shown in FIG. 18, the door is locked by the user's pushing force. The buckle plate (not shown) pushes open the latch pin 100 , so that the rotatable latch pin 100 rotates in a counterclockwise direction and is introduced into the interior of the door lock mortise.

When the door is fully opened and the user turns the key back to the original position, as shown in FIG. 19 , the second handle block 920 is also rotated to return to the original position at the same time, so that the second handle block 920 and the emergency lever 400 are separated from each other And by the elastic force of the spring 410, the emergency lever 400 rotates counterclockwise in the drawing and returns to the original position, so that the emergency lever 400 and the first fixing bolt pulling rod 210 are separated from each other, so that the first fixing bolt pulling rod 210 And the second fixing bolt pulling lever 211 can be rotated, so that the fixing bolt 200 is drawn out by the driving of the first motor 221, and the emergency lever 400 and the lower end stopper projection 710 of the latch lever 700 are separated from each other, thereby The latch lever 700 is rotatable so that by the elastic force of the spring 740 formed in the pressing portion 730 of the latch lever 700, the latch lever 700 rotates clockwise in the drawing with the rotation shaft 701 as the center, thereby latching The rotation restricting portion 720 of the lever 700 restricts the rotation of the latch pin 100 by pressing the protruding portion 120 of the latch pin 100 .

After that, when the door is closed again, the latch pin 100 applies a force to the inclined surface opposite to when the door is opened. That is, the striker plate of the door collides with the inclined surface of the latch pin 100, and the latch pin 100 is pushed toward the inside of the door lock mortice, thereby pushing the spring 130 backward, so that the latch pin 100 does not stop. It enters the inside of the housing 10 linearly in a rotational manner. When the door is completely closed, by the force of the spring 130, the latch pin 100 protrudes again toward the slot of the door frame.

In addition, when the sub-lock 300 is introduced into the front part 20 of the main body, whereby the detection part 303 of the sub-lock 300 is separated from the sub-lock detection sensor 830 and the closing of the door is detected by the sub-lock detection sensor 830, as shown in Fig. 6 As shown in 20, first, the first motor 221 is driven, whereby the first driving gear 222 and the bolt pulling gear 213 are rotated, whereby the first bolt pulling rod 210 and the second bolt pulling rod 210 and the second bolt pulling rod 210 integrally formed with the bolt pulling gear 213 are rotated. The fixing bolt pulling rod 211 is rotated together in the clockwise direction in the drawing to move the end of the second fixing bolt pulling rod 211 to the upper end in the long hole 202 of the slider 201, thereby connecting the slider 201 and the integrally formed therewith. The fixing bolt 200 is drawn out from the front part 20 of the main body, so that the door is in a locked state.

On the other hand, FIG. 21 is a perspective view showing the internal structure of a door lock mortise according to another embodiment of the present invention.

Next, referring to FIG. 21 , a door lock mortise according to another embodiment of the present invention will be described. For convenience of description, the description of the same structure as that of the above-described embodiment will be omitted.

As shown in FIG. 21 , a door lock mortise according to another embodiment of the present invention includes a housing 10 , a main body front 20 , a latch pin 100 , a first gear box 220 and a second gear box 140 , a fixing bolt 200 , an auxiliary The fixing bolt 500, the sub-lock 300, the first handle block 910, the second handle block 920, the third handle block 930 and the PCB 330, the housing 10, the front part of the main body 20, the latch pin 100, the first gear box 220 and the second The gear box 140 and the PCB 330 are the same as those of the previously described embodiment, so the detailed description is omitted.

The bolt 200 is a structure for locking or unlocking the door by being drawn and drawn through the introduction hole of the front part 20 of the main body, and a bolt pulling rod 210 that rotates according to external force or power is integrally formed at the rear of the bolt 200 to move forward and backward. The slider 201 that moves linearly to draw the fixing pin 200 in and out from the front part 20 of the main body.

The fixing bolt pulling rod 210 is introduced into the slider groove 204 formed in the slider 201 , and the fixing bolt pulling rod 210 is formed by connecting with the emergency rod 400 .

Accordingly, when the bolt drawbar 210 receives the driving force of the first motor 221 and rotates clockwise or counterclockwise in the drawing, the bolt drawbar 210 moves along the slider groove 204 of the slider 201 The slider 201 is pushed forward or pulled backward by contacting the inner surface of the slider groove 204 , so as to lead out or introduce the fixing bolt 200 . In addition, when the emergency lever 400 comes into contact with the first handle block 910 and the third handle block 930 which are rotated by the operation of the push-pull handle (not shown) of the user, or the second handle block 920 which is rotated by the key operation, and rotates , the fixing bolt pulling rod 210 in contact with the emergency lever 400 rotates and moves along the sliding block groove 204 of the sliding block 201 to introduce the fixing bolt 200 .

In the first handle block 910, the second handle block 920, and the third handle block 930, the first handle block 910 and the third handle block 930 are integrally coupled to rotate simultaneously, and the second handle block 920 is inserted into the first handle block 910 and Between the coupling intervals of the third handle block 930, protrusions are formed in two directions on one side of the second handle block 920 and the third handle block 930, thereby rotating in two directions clockwise and counterclockwise to rotate the emergency lever 400.

With such a structure, when the user pushes or pulls the push-pull handle (not shown) indoors, the second handle block 920 is in a fixed state, and the third handle block 930 rotates. At this time, because the third handle block 930 Since it is connected to the first handle block 910, it rotates together. The third handle block 930 rotates clockwise or counterclockwise in the drawing to rotate the abutting emergency lever 400, which is rotated by the third handle block 930. The emergency lever 400 is in contact with the fixing bolt pulling rod 210 to make the fixing bolt pulling rod 210 rotate counterclockwise in the drawing.

Thereby, the fixing bolt pulling rod 210 moves along the sliding block groove 204 of the sliding block 201 , thereby abutting with the inner wall of the right side of the sliding block groove 204 in the drawing, thereby introducing the fixing bolt 200 into the front part 20 of the main body Then, the emergency lever 400 is further rotated in the clockwise direction in the drawing to come into contact with the lower end stopper projection 710 of the latch lever 700, thereby rotating the latch lever 700 around the rotation shaft 701, thereby restricting the rotation The portion 720 is disengaged from the protrusion 120 of the latch pin 100 , allowing rotation of the latch pin 100 .

After that, the emergency lever 400 is rotated counterclockwise in the drawing by the spring 410 to return to the original position, so that the emergency lever 400 and the bolt drawbar 210 are separated from each other, whereby the bolt drawbar 210 can be rotated to become the pass In a state where the fixing bolt 200 can be drawn out by driving the first motor 221 , the latch lever 700 can rotate as the emergency lever 400 and the lower end stopper projection 710 of the latch lever 700 are separated from each other. Due to the elastic force of the spring 740 of the pressing portion 730, the latch lever 700 rotates clockwise in the drawing, whereby the rotation restricting portion 720 of the latch lever 700 is introduced through the side groove 151 of the frame 150 to meet the The protrusion 120 of the spring pin 100 is pressed to limit the rotation of the spring pin 100 .

On the other hand, when the user inserts the key outdoors and rotates, the first handle block 910 and the third handle block 930 are in a fixed state, and only the second handle block 205 rotates together with the key.

With this structure, when the user inserts the key outdoors and rotates, the first handle block 910 and the third handle block 930 are in a fixed state, and only the second handle block 920 is clockwise or counterclockwise in the drawing. The emergency lever 400 in contact with the rotation is rotated, and the emergency lever 400 rotated by the second handle block 920 abuts against the bolt drawbar 210 , thereby rotating the bolt drawbar 210 counterclockwise in the drawing.

As a result, the bolt pulling rod 210 rotates and slides along the slider groove 204 of the slider 201 to abut against the right inner wall of the slider groove 204 , thereby introducing the bolt 200 into the front part 20 of the main body, and then the emergency lever 400 In the drawing, the latch lever 700 is further rotated clockwise to abut against the lower end stopper projection 710 of the latch lever 700 , whereby the latch lever 700 is rotated about the rotation axis 701 , and the rotation restricting portion 720 is released from the latch pin 100 . The protrusions 120 of the contactor are disengaged, thereby allowing the latch pin 100 to rotate.

After that, when the user re-rotates the key to the original position, the second handle block 920 also rotates to return to the original position at the same time and is separated from the emergency lever 400, so that the emergency lever 400 is also shown in the drawing by the elastic force of the spring 410. Rotate counterclockwise to return to the original position.

In addition, as the emergency lever 400 is rotated counterclockwise in the drawing by the spring 410 to return to the original position, the emergency lever 400 and the bolt drawbar 210 are separated from each other, whereby the bolt drawbar 210 can be rotated to become By driving the first motor 221, the latch lever 700 can be rotated as the emergency lever 400 and the lower end stopper projection 710 of the latch lever 700 are separated from each other, and the latch lever 700 passes through The elastic force of the spring 740 formed in the pressing portion 730 of the latch lever 700 rotates clockwise in the drawing, so that the rotation restricting portion 720 of the latch lever 700 is introduced through the side groove 151 of the frame 150, thereby The protrusion 120 of the latch pin 100 is pressed, thereby restricting the rotation of the latch pin 100 .
