1 to 10, the door lock device 1 according to the present embodiment includes a cap member 10, a housing 20, a catch 30, a latch bolt 40, and a driving unit.
The cap member 10 is disposed in the clamp insertion hole 4 formed in the door post (3). The cap member 10 has a fixing portion 11 fixed to the inner surface of the clamp insertion hole 4, and a protrusion 12 protruding from the fixing portion 11 and the insertion hole 13 is formed through. The central axis of the insertion hole 13 is parallel to the vertical direction. Meanwhile, the latch bolt insertion hole 5 is also formed in the door post 3.
The housing 20 is inserted into the door 2 so as not to protrude and immerse with respect to the side of the door 2 shown in FIG. 1. The housing 20 has a case 21, a front plate 22 and a cover 23 which are coupled to each other. The front plate 22 is provided with a latch entrance hole 221 through which the clasp 30 enters and a latch bolt entrance hole 222 through which the latch bolt 40 described later enters and exits. In addition, long holes 215 and 231 are formed in the case 21 and the cover 23 in the horizontal direction, respectively. In addition, inside the case 21, a locking member 24 formed long in the linear movement direction of the clamp 30 described later is fixed.
The catch 30 is for locking and releasing the door 2, and is inserted into the clamp insert hole 4 to lock the door 2 primarily and to be inserted into the insert hole 13 of the cap member. Lock 2) secondarily.
The catch 30 is coupled to the housing 20 so as to be linearly movable in a direction protruding and immersed with respect to the housing 20, that is, in a horizontal direction, whereby the catch 30 is a reference position shown in FIG. 1 and FIG. 2. It is possible to move linearly between the departure positions shown in. In the reference position, the catch 30 is disposed inside the housing 20 without protruding from the housing 20. However, in the disengaged position, the catch 30 is projected with respect to the housing and inserted into the catch clamp insertion hole 4. However, in the disengaged position, the clamp 30 is in a disengaged state without being inserted into the insertion hole 13 of the cap member. On the other hand, the linear movement of the clamp is guided by the guide portion 211 protruding to the case.
In addition, the clamp 30 is rotatably coupled to the housing relative to the housing 20, whereby the clamp is rotatable between the release position shown in FIG. 2 and the insertion position shown in FIG. In the insertion position, the clamp 30 is inserted into the insertion hole 13 of the cap member in the state of being inserted into the clamp insertion hole 4. And, since the lock 30 is rotated between the release position and the insertion position, the moving direction of the lock 30 is different from the linear movement direction of the lock 30 between the release position and the insertion position.
The catch 30 includes an insertion portion 31, a protrusion 32, an inclined portion 33, and a locking jaw 34.
The insertion portion 31 is a portion to be inserted into the insertion hole 13 of the cap member, and is formed below the tip of the clamp 30.
The protrusions 32 are provided with a pair, and each protrusion 32 is inserted into the long holes 215 and 231 formed in the case and the cover, respectively. Each protrusion 32 guides the linear movement of the clamp. Further, when the catches are located at the reference position shown in FIG. 1 and the release position shown in FIG. 2, respectively, the projections 32 are disposed on one side and the other side in the longitudinal direction of the long holes 215 and 231, respectively, and the long holes 231 Since it comes in contact with the inner surface of the clamp 30 is no longer able to move linearly. On the other hand, when the clamp 30 is rotated between the disengaged position and the insertion position, each projection 32 becomes the rotation center of the clamp 30.
The inclined portion 33 is an inclined surface formed to be inclined with respect to the linear movement direction of the clasp 30.
The locking jaw 34 is connected to the inclined portion 33 and is a plane perpendicular to the linear movement direction of the clamp 30.
In addition, the clamping portion 30 is also provided with a stepped portion 37 which is stepped with respect to the locking portion 35, the pressing portion 36, and the pressing portion 36.
The latch bolt 40 is linearly movable in the direction in which it protrudes and immerses with respect to the housing. The latch bolt 40 is inserted into the latch bolt insertion hole 5 in the state in which the door 2 is closed to prevent the door 2 from being opened arbitrarily by wind or weak vibration. The latch bolt 40 is elastically biased in a direction in which the latch bolt 40 protrudes from the housing 20 by the compression coil spring (not shown).
The drive unit is for driving not only the linear drive but also the rotation of the clamp 30, and includes a rotating member 50, a stopper 51, and a linear moving member 52.
The rotating member 50 is linearly moved together with the clamp when the straight clamp 30 is moved and is coupled to the clamp so as to be relatively rotatable with respect to the clamp 30. That is, the rotary member 50 and the step portion 37 of the clamping body are coupled to each other by the pivot shaft p, so that the rotation member 50 moves together with the clamping member 30 when the linear member of the clamping member 30 moves in the reference position and the separated position. Moving linearly between, furthermore, the rotation member 50 is rotatable between the departure position and the insertion position about the pivot axis (p). The rotating member 50 has a substantially "L" shape, and has a sliding portion 501 and a pressurized portion 502.
The rotating member 50 rotates in conjunction with the rotation between the release position and the insertion position of the clamp 30 as described later.
First, when the rotating member 50 is rotated counterclockwise in the position shown in Figure 2, the pressing member 502 of the rotating member is to press the pressing portion 36 of the clamp, so that the clamp 30 It rotates counterclockwise about the protrusion 32. Thus, the insertion portion 31 of the clamp is inserted into the insertion hole 13 of the cap member. On the other hand, when the clamp 30 is rotated clockwise in the state where the clamp 30 is located at the insertion position shown in FIG. 3, the pressing part 36 of the clamp presses the press part 502 of the rotating member. Since the rotating member 50 is rotated in the clockwise direction, it is disposed at the position shown by the virtual line in FIG.
The stopper 51 is fixed inside the housing 20. The stopper 51 is formed long in the linear movement direction of the clasp 30. Then, the stopper 51 is disposed below the linear moving member 52.
The linear movement member 52 is coupled to the housing to enable reciprocating linear movement with respect to the housing 20. As described later, the linear member 52 is linked to the linear movement of the linear member 52 is connected to the clamp 30 so that the clamp 30 rotates and moves linearly.
First, in a state in which the clamp 30 is located at the insertion position shown in FIG. 3, when the linear member 52 moves linearly to the right, the linear member 52 presses the inclined portion 33 of the clamp. Therefore, the clamp 30 is rotated in the clockwise direction is located in the disengaged position. At this time, since the locking portion 35 of the clamping mechanism is caught by the locking member 24, the pressing force of the linear movement member 52 is prevented from acting as a linear driving force of the clamping mechanism 30, so that the locking clamp is only rotated. After that, when the clamp 30 continues to move to the right in a straight line, the linear movable member 52 contacts the latching jaw 34 of the clamp and presses the latching jaw 34 to the right. ), And the clamp 30 is moved to the right side so that it can be arranged at the reference position. At this time, since the locking member 24 deviates from the linear movement path of the locking portion 35 of the clamp, the locking between the locking portion 35 and the locking member 24 of the clamp is released so that the clamp 30 is moved linearly. It becomes possible. In addition, in the process of moving the catch 30 from the detached position to the reference position, the sliding part 501 of the rotating member is pressed by the stopper 51 so that the rotating member 50 rotates clockwise. The sliding part 501 of the rotating member is slid while contacting the upper surface of the stopper 51.
On the other hand, in a state in which the clamp 30 is located at the reference position shown in FIG. 1, when the linear member 52 moves linearly to the left, the linear member 52 moves the press member 502 of the rotating member. Rotation driving force is generated in the rotating member 50 by pressing, but since the sliding part 501 of the rotating member slides along the lengthwise direction of the stopper 51 in contact with the stopper 51, the clamp 30 is It moves straight to the left and is placed in the departure position. That is, the pressing force of the linear moving member 52 is converted into a linear driving force of the clamping portion 30 by the contact sliding between the sliding portion 501 and the stopper 51 of the rotating member and transmitted. After that, if the linear member 52 is moved further linearly to the left, the contact between the sliding portion 501 and the stopper 51 of the rotary member is released while the pressing force of the linear member 52 is reduced. Converted into rotational driving force. In addition, since the rotating member 50 pressurized by the linear movement member 52 presses the pressing portion 36 of the clamp while rotating in the clockwise direction, the clamp 30 is rotated in the clockwise direction and disposed at the insertion position. .
On the other hand, the linear movement member 52 is formed with a cylindrical coupling hole 521.
In addition, the drive unit includes a medium member 60, a first auxiliary pressure rotating member 70, a main pressure rotating member 80, a second auxiliary pressure rotating member 90, and a user-operated rotating member (not shown). H), a rotating pin 100, a user interface (not shown), and a motor 101 are further provided.

The hinge portion 61 has a shape corresponding to the coupling hole 521 of the linear moving member and is inserted into the coupling hole 521. The intermediate member 60 is rotatable about the hinge portion 61 within a predetermined angle range, that is, between the first position shown in FIG. 9 and the second position shown in FIG. 10. In the first position and the second position, since the extension part 62 to be described later is caught by the linear moving member 52, the intermediate member 60 can no longer rotate.
The extension portion 62 is formed in a plate shape extending in the linear movement direction of the linear movement member 52 and connected to the end of the hinge portion 61.
The to-be-pressed part 63 is formed to protrude in the thickness direction of the door 2 from one side of the extension part 62. The pressurized part 63 is provided with a first pressurized part 631, a second pressurized part 632, a third pressurized part 633, and a fourth pressurized part 634. The first pressurized part 631 and the second pressurized part 632 are formed to be connected to each other on one side of the pressurized part 63, and the third pressurized part 633 and the fourth pressurized part 634.

Direction of rotation.
The second pressurized part 632 and the fourth pressurized part 634 are surfaces formed orthogonal to the linear movement direction of the intermediate member 60, and the first auxiliary pressurizing member 70 and the main pressurizing rotation described later. When the member 80 and the second auxiliary pressing rotary member 90 is rotated, the first auxiliary pressing rotary member 70, the main pressing rotary member 80 and the second auxiliary pressing rotary member 90 are respectively pressed. Thus, the intermediate member 60 is linearly moved left or right.
On the other hand, the intermediate member 60 is elastically biased in the direction approaching the second auxiliary pressing rotary member 90 to be described later by the first spring (65). One side of the first spring 65 is welded and fixed to the linear moving member 52, and the other side of the first spring 65 is supported by the extension 62 of the intermediate member to support the extension 62. Pressurize to the auxiliary pressure rotating member.
In addition, one end and the other end of the second spring 66 are fixed to each of the protruding pillar 64 protruding from the intermediate member 60 and the protruding pillar 212 protruding from the case 21. Here, the second spring 66 exerts an elastic force on the left and right directions of the intermediate member 60 when the intermediate member 60 moves to the left and right, respectively.

The first pressing portion 73 is formed extending from the side of the body portion 71 in a direction perpendicular to the thickness direction of the door (2). In a state where the first auxiliary pressing rotary member 70 is arranged as shown in Fig. 9, the first pressing part 73 is an intermediate member upon the rotation of the first auxiliary pressing rotary member 70 in the clockwise direction. The first pressurized portion 631 is pressed to rotate the intermediate member 60 to the second position. As such, when the first auxiliary pressing rotary member 70 continues to rotate in the state in which the intermediate member 60 is rotated, the first pressing unit 73 presses the second pressurized portion 632 of the intermediate member to press the intermediate member. 60 is linearly moved to the right with the linear movement member 52. On the other hand, since the first pressing portion 73 is in contact with the first stopper portion 213 protruding from the inner surface of the case 21, the first auxiliary pressing rotary member 70 in the state shown in FIG. Rotation in the direction is limited.
The main pressing rotary member 80 is rotatably coupled to the inside of the housing 20. The main pressing rotary member 80 is disposed coaxially with the first auxiliary pressing rotary member 70 and is rotatable relative to the first auxiliary pressing rotary member 70. The main pressurizing rotary member 80 is provided with a body portion 81, a pair of pressing portions 82 and 83, and a gear portion 84.
The body portion 81 is formed in a plate shape. A pair of fitting holes 811 and 812 are formed in the body portion 81 in an arc shape. In the body portion 81, a coupling hole 813 into which the rotating body 103 to be described later is fitted is formed through.
The pair of pressing portions 82 and 83 protrude from the body portion 81 and are disposed to face each other. The pressurized part 63 is disposed between the pair of pressurizing parts 82 and 83. In addition, since the second pressurized part 632 and the fourth pressurized part 634 are disposed on the rotation paths of the pair of pressing parts 82 and 83, the main pressurizing rotating member 80 is clockwise or counterclockwise. The pair of pressing portions 82 and 83 pressurizes the second pressurized portion 632 or the fourth pressurized portion 634 as it rotates in the direction. When the pair of pressing portions 82 and 83 press the second pressurized portion 632 or the fourth pressurized portion 634 as described above, the intermediate member 60 is a linear moving member without being rotated. Along with 52, the linear movement is performed in the left or right direction.
The gear portion 84 is formed on the outer surface of the body portion 81 and includes the teeth of the abdomen.
The second auxiliary pressing rotary member 90 is rotatably installed in the housing 20. The second auxiliary pressing rotary member 90 is disposed coaxially with the first auxiliary pressing rotating member 70 and the main pressing rotating member 80, and the first auxiliary pressing rotating member 70 and the main pressing rotating member 80 are disposed. Relative rotation is possible. The second auxiliary pressing rotary member 90 includes a body portion 91, a second insertion protrusion 92, and a second pressing portion 93.
The body portion 91 is formed in a plate shape. The body portion 91 is formed with a through hole 912 into which an arc-shaped second insertion groove 911 and a rotating body 103 to be described later are fitted. The first insertion protrusion part 72 is inserted into the second insertion groove part 911, and the second insertion groove part 911 is formed to include the rotation path of the first insertion protrusion part 72. When the 70 is rotated, the first insertion protrusion 72 is not caught by the inner surface of the second insertion groove 911.
The second insertion protrusion part 92 is provided with a pair, and each second insertion protrusion part 92 is formed to protrude in the thickness direction of the door 2 from the surfaces facing in the opposite directions of the body part 91. The second insertion protrusion part 92 is inserted into the first insertion groove part 711, and since the first insertion groove part 711 is formed to include the rotation path of the second insertion protrusion part 92, the second auxiliary pressure rotating member 90 is provided. ), The second insertion protrusion part 92 is not caught by the inner surface of the first insertion groove part 711 during the rotation of.
The second pressing portion 93 is formed extending from the one side of the body portion 91 in a direction perpendicular to the thickness direction of the door (2). The second pressing part 93 is disposed on the same plane as the first pressing part 92.
In the state where the second auxiliary pressing rotary member 90 is arranged as shown in FIG. 9, the second pressing unit 93 is adapted to rotate when the second auxiliary pressing rotary member 90 rotates in the counterclockwise direction. The third pressurized portion 633 of the member 60 is pressed to rotate the intermediate member 60 to the second position. As such, when the second auxiliary pressing rotary member 90 continues to rotate in the state in which the intermediate member 60 is rotated, the second pressing unit 93 presses the fourth pressurized portion 634 of the intermediate member to mediate the intermediate member. 60 is linearly moved to the left with the linear movement member 52. On the other hand, since the second pressing portion 93 is in contact with the second stopper portion 214 protruding from the inner surface of the case 21, the second auxiliary pressing rotary member 90 is clockwise in the state shown in FIG. Rotation is restricted.
On the other hand, the first auxiliary pressing rotary member 70 and the second auxiliary pressing rotary member 90 in the direction in which the first pressing unit 73 and the second pressing unit 93 are spaced apart from each other by the third spring (95). It is elastically biased.

In addition, when the intermediate member 60 is pressurized by the first auxiliary pressing rotary member 70 and the second auxiliary pressing rotary member 90 to move linearly, the pressurized portion 63 of the intermediate member is shown in FIG. Since the linear movement is rotated from the first position shown, the linear movement path of the intermediate member 60 is out of the rotation path of the main pressure rotating member (80). Therefore, the intermediate member 60 is smoothly linearly moved without being caught by the main pressure rotating member 80.
The user-operated rotating member (not shown) is rotatably installed on the indoor side and the outdoor side of the door 2, respectively. In the present embodiment, the user-operated rotating member is formed of a handle having a handle formed in a bar shape and elongated in one direction, similar to a handle provided in a conventional door lock apparatus. The user-operated rotating member, that is, the handle, is disposed coaxially with the first auxiliary pressing rotary member 70 and the second auxiliary pressing rotary member 90. The outdoor handle and the indoor handle are linked to the rotation to be connected to the outdoor handle and the indoor handle so that the latch bolt 40 moves in the direction immersed with respect to the housing 20 and is separated from the latch bolt insertion hole 5. do. When the indoor handle and the outdoor handle are rotated and then released, they are elastically biased to return to their original positions as is widely known.

The rotary pin 100 is inserted into the first insertion groove 711, the second insertion groove 911, and the fitting hole 811, and is disposed between the first insertion protrusion 72 and the second insertion protrusion 92. . In addition, the rotary pin 100 is disposed in the center of each of the first insertion groove 711 and the second insertion groove 911. In addition, the rotation pin 100 rotates clockwise or counterclockwise along the forming direction of the first insertion groove 711 or the second insertion groove 911 when the interior handle is rotated. The protrusion 72 or the second insertion protrusion 92 is rotated clockwise or counterclockwise. As such, when the first insertion protrusion 72 or the second insertion protrusion 92 rotates, the first auxiliary pressing rotation member 70 or the second auxiliary pressing rotation member 90 also rotates in the same direction. Rotating pin 100 is also elastically biased to return to the position shown in FIG. 3, by rotating the handle to rotate the rotating pin 100 in a clockwise or counterclockwise direction and then release the handle. Return to the position shown in FIG.
The user interface (not shown) is installed on the outdoor side of the door 2 to authenticate the user. The user interface may be variously set, such as a keypad consisting of a plurality of buttons or a fingerprint recognition unit that recognizes a user's fingerprint.
The motor 101 is operated by a power source to rotate forward or reverse. The motor 101 is driven when user authentication is made through the user interface. A gear member 102 having a plurality of teeth formed on an outer circumferential surface thereof is fixed to an output shaft of the motor 101, and the gear member 102 is directly engaged with the gear portion 84 of the main pressure rotating member.
On the other hand, the rotating body 103 is inserted into the first auxiliary pressing rotary member 70, the second auxiliary pressing rotary member 90 and the main pressing rotary member 80. The rotating body 103 becomes a center of rotation of each of the first auxiliary pressing rotary member 70, the second auxiliary pressing rotating member 90, and the main pressing rotating member 80. Both ends of the rotating body 103 are fitted to the case 21 and the cover 23.
Hereinafter, an operation process of the door lock device 1 configured as described above will be described.
As shown in FIGS. 3 and 6, when the user is authenticated through the user interface in the locked state, the motor 101 may be rotated forward. Thus, the main pressing member 80 may be rotated clockwise. It can be rotated. In addition, since the pressing part 82 of the main pressurizing rotating member presses the second pressurized portion 632 of the intermediary member during the rotation of the main pressurizing rotating member 80, the intermediate member 60 is a linear moving member ( 52) to the right. When the linear movement member 52 is moved to the right as described above, since the linear movement member 52 sequentially presses the inclined portion 33 and the locking jaw 34 of the clamp, the clamp 30 is shown in FIG. 2. It is possible to be positioned at the reference position shown in Figure 1 via the separation position shown.
On the other hand, after the unlocked door is closed, if the motor 101 is rotated in reverse, the main pressing rotation member 80 can be rotated counterclockwise. In addition, since the pressing part 83 of the main pressurizing rotating member presses the fourth pressurized part 634 of the intermediate member during the rotation of the main pressurizing rotating member 80, the intermediate member 60 is a linear moving member ( 52) to the left. When the linear movement member 52 is moved to the left as described above, the linear movement member 52 presses the pressurized portion 502 of the rotating member, and the sliding portion 501 of the rotating member contacts the stopper 51. Since the rotation of the rotating member 50 is prevented, the pressing force of the linear moving member 52 acts as a driving force for linearly moving the clamp 30. Further, in the state where the clamping force 30 pressed by the linear moving member 52 is disposed in the disengagement position shown in FIG. 2, the contact between the sliding portion 501 and the stopper 51 of the rotating member is released, thereby making it straight. The pressing force of the movable member 52 acts as a rotational driving force of the rotating member 50, so that the clamp 30 can be positioned at the insertion position shown in FIG.
In addition, as shown in FIGS. 3 and 6, when the door is locked and the handle is rotated to unlock the door 2 indoors, the rotating pin 100 rotates clockwise with the handle. Since the first insertion protrusion 72 is pressed, the first auxiliary pressing rotary member 70 rotates clockwise. In addition, in the process of rotating the first auxiliary pressing rotary member 70, the first pressing part 73 of the first auxiliary pressing rotating member 70 opens the first pressing part 631 and the second pressing part 632 of the pressurized part. Since the pressure is sequentially applied, the intermediate member 60 is disposed as shown in FIGS. 7 and 10 by linearly moving to the right after rotating clockwise to the second position. As such, when the intermediate member 60 is moved to the right, it is possible to place the clamp 30 in the reference position through the above-described process.
On the other hand, when the handle is released after the door is unlocked as shown in FIG. 7, the first auxiliary pressure rotating member 70 and the rotating pin 100 return to the position shown in FIG. 6. In this state, when the rotating pin 100 is rotated counterclockwise by rotating the handle, the second pin pressing rotation member 90 is rotated because the rotating pin 100 presses the second insertion protrusion 92. It is possible to rotate counterclockwise as shown in FIG. In the process of rotating the second auxiliary pressing rotary member 90, the second pressing part 93 of the second auxiliary pressing rotating member 90 is the third pressurized part 633 and the fourth pressurized part 634 of the pressurized part. Since the pressure is sequentially, the intermediate member 60 is moved linearly to the left after rotating clockwise to the second position. As such, when the intermediate member 60 is moved to the left side, it is possible to place the clamp 30 in the insertion position through the above-described process.
As described above, in the door lock device 1 of the present embodiment, the clamp 1 is first locked into the clamp insertion hole 4 and further, in the state where the clamp 1 is inserted into the clamp insertion hole 4. The second locking is inserted into the insertion hole 13 of the cap member. That is, the effect that the door 2 is double locked is produced. Therefore, physical hacking on the clamp 30 is virtually impossible, thereby improving the security of the door lock device 1.
And, by simply turning the handle in the room, you can release all the double locking of the door, so in case of emergency, for example, in case of fire or earthquake, even if the person in the room is mentally panic, It can be easily escaped by rotating. Therefore, it is possible to minimize human injury.
On the other hand, in the present embodiment, the clasp is configured to be rotatable between the disengaged position and the insertion position, but the clasp may be configured to be linearly movable between the disengaged position and the insertion position.
In the door lock apparatus 1a shown in FIG. 11 and FIG. 12, the 1st long hole 231 and the 2nd long hole 232 are formed in the housing 20a. The first long hole 231 is formed to be long in the horizontal direction in the case and the cover 23a and is formed in parallel to each other. The second long hole 232 is formed in the case and the cover 23a in pairs, respectively. In addition, the pair of second long holes 232 formed in the case and the cover 23a are formed long in the vertical direction and are formed to be parallel to each other. In addition, the pair of second long holes 232 are connected to the first long holes 231, respectively. 11 and 12 omit the first and second holes formed in the case and the case.
And four projections 32 are formed in the clamp 30a. The pair of protrusions 32 are formed on one side of the clamp 30a, and the other pair of protrusions are formed on the other side of the clamp, that is, the surface facing in the opposite direction to one side. Then, the pair of protrusions 32 formed on one side and the other side of the clamp are respectively disposed at the position as shown in FIG. 11 when the clamp 30a is disposed at the reference position, but the clamp 30a is inserted. When placed in position, it is placed in the position shown in FIG.
As described above, in the door lock device 1a of the present embodiment, the projection 32 for guiding the movement of the clamp 30a moves vertically in the second long hole 232 after horizontal movement in the first long hole 231. Consists of. Therefore, the clamp 30a can be positioned at the reference position, the detachment position, and the insertion position by the horizontal movement and the vertical movement.
As mentioned above, the present invention has been described in detail with reference to preferred embodiments, but the present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art within the technical idea of the present invention. It is obvious.
For example, in the present embodiment, the handle is rotatably coupled to the indoor side and the outdoor side of the door, but the handle is not necessarily configured to be provided. Generally, a door lock device with a handle is called a primary key, while a door lock device without a handle is called an auxiliary key. The door lock device, which is called an auxiliary key, is not provided with a handle and a latch bolt unlike in the above-described embodiment, and the housing is coupled to the interior side of the door. Then, the clamp is inserted into and separated from the clamping hole is formed in a separate part coupled to the door jamb, the cap member is installed in the clamping hole formed in this separate part.
In addition, even when the door lock device of the present embodiment is configured in the form of an auxiliary key, by configuring the user-operated rotating member to the knob rotatably installed in the case, it is also possible to configure the rotary pin to rotate in conjunction with the rotation of the knob. .
In addition, in this embodiment, the cap member is configured to be disposed inside the clamping hole, the cap member may be coupled to protrude to the door jamb. That is, it is preferable that the cap member is coupled to the interior side of the doorpost without the clamp insertion hole being formed in the doorpost to protrude from the doorpost. In this case, the door lock device has a structure called an auxiliary key. Therefore, the clamp is moved in a straight line and rotational movement in the horizontal direction or a straight line in the horizontal and vertical direction, and is inserted into the insertion hole of the cap member.
In addition, in the present embodiment, the pressurized portion of the intermediate member is formed to protrude from the extension portion, but the pressurized portion of the intermediate member may be configured to have a groove shape in the extension portion.
