[0111] The automatic lock and the lock cabinet having the same according to the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0112] Refer to Figures 1 to 11 As shown, the automatic lock according to the embodiments of the present invention includes an outer handle 10, an inner lock body 20, a lock rod 30, a driving assembly 40 and a power supply assembly 13.

[0113] Specifically, the outer handle 10 is adapted to be installed on the outer side of the object to be locked 50. The inner lock body 20 is adapted to be installed on the inner side of the object to be locked 50. Both ends of the lock rod 30 are respectively in transmission connection with the outer handle 10 and the inner lock body 20. During installation, installation holes are formed in the object to be locked 50. For example, when the object to be locked 50 is a door body, installation holes are formed at a predetermined position on the door body away from the door edge. The outer handle 10 can be fixed to the outer side of the door body by fasteners such as screws, and the inner lock body 20 is fixed to the inner side of the door body by fasteners such as screws. After the lock rod 30 passes through the installation hole, it is connected to the inner lock body 20.

[0114] The driving assembly 40 is arranged inside the outer handle 10, and the driving assembly 40 drives the lock rod 30 to rotate so as to unlock or lock the inner lock body 20. The power supply assembly 13 is arranged inside the outer handle 10, and the driving assembly 40 is electrically connected to the power supply assembly 13, and the power supply assembly 13 supplies power to the driving assembly 40.

[0115] That is to say, the driving component 40 is inside the outer handle 10 and connected to the lock rod 30. The lock rod 30 can be driven to rotate by the driving component 40. Since the lock rod 30 is connected to the inner lock body 20, when the lock rod 30 rotates, the inner lock body 20 can be driven to unlock or lock. In addition, the power supply component 13 is arranged inside the outer handle 10, and the power supply component 13 can supply power to the driving component 40 to ensure that the driving component 40 can automatically unlock or lock in the powered state.

[0116] It can be understood that the outer handle 10 can be configured into a structure that can be disassembled or is convenient for the installation of the power supply component 13. Exemplarily, the outer handle 10 includes a main body 101, a first housing 103 and a second housing 102. The first housing 103 and the second housing 102 are respectively buckled on both sides of the main body 101. A power supply compartment P10 is provided on the main body 101. When the first housing 103 is disassembled, the power supply compartment P10 can be opened to facilitate the replacement of the power supply component 13 in the power supply compartment P10.

[0117] It should be noted that in the automatic lock in the related art, the power supply component 13 is usually arranged inside the inner lock body 20. When the automatic lock is applied to an object such as a cabinet, if the power supply component 13 runs out of power and the automatic lock is in the locked state, at this time, the inner lock body 20 is located inside the cabinet. Since the cabinet is locked and cannot be opened, the power supply component 13 in the inner lock body 20 cannot be replaced, and only other methods can be used to unlock, such as professional maintenance unlocking, or violent removal of the lock, etc., which brings great trouble to the user. In the automatic lock of the present application, the power supply component 13 is arranged inside the outer handle 10. In the case of the power supply component 13 running out of power, the power supply component 13 can be replaced from the outside.

[0118] According to the automatic lock provided by the embodiment of the present invention, by adopting the method of arranging the driving component 40 and the power supply component 13 inside the outer handle, in the locked state, if the power supply component 13 lacks power and cannot unlock, the power supply component 13 can be directly replaced from the outside to achieve unlocking, which is more convenient to use, solves the problem that it is difficult to unlock due to the lack of power of the power supply component 13 in the inner lock body 20, and achieves the technical effect of quickly replacing the power supply component 13 and unlocking.

[0119] Refer to Figure 3 As shown, in some embodiments of the present invention, the driving component 40 includes an input module 401, a control circuit board 402 and a driving motor 403. The input module 401 is used to trigger an unlocking instruction. The input module 401 can be but is not limited to a password button, a touch button, a fingerprint module, an infrared face recognition module, etc. The user triggers the unlocking instruction through the input module 401. For example, the unlocking instruction is triggered by inputting a password through the password button or the touch button, the unlocking instruction is triggered after fingerprint recognition is input through the fingerprint module, or the unlocking instruction is triggered after face recognition is performed through the infrared face recognition module.

[0120] The control circuit board 402 is electrically connected to the input module 401 and is configured to output a control signal according to an unlocking instruction. The control circuit board 402 can be configured to match the shape of the outer handle 10, so as to facilitate the installation of the control circuit board 402 inside the outer handle 10. The driving motor 403 is electrically connected to the control circuit board 402, and the driving motor 403 is in transmission connection with the lock rod 30 and is configured to drive the lock rod 30 to rotate according to the control signal, so as to unlock the inner lock body 20. Preferably, the axis of the driving motor 403 is perpendicular to the outer handle 10, and the lock rod 30 is coaxially connected to the output shaft of the driving motor 403. After the outer handle 10 is installed on the object to be locked 50, the lock rod 30 passes through the mounting hole on the object to be locked 50.

[0121] During use, the user can trigger an unlocking instruction through the input module 401. The control circuit board 402 outputs a control signal to the driving motor 403 according to the unlocking instruction. The driving motor 403 rotates and works under the control of the control signal, and then drives the lock rod 30 to rotate. Since the lock rod 30 is connected to the inner lock body 20 after passing through the mounting hole on the object to be locked 50, the lock rod 30 further drives the inner lock body 20 to release the locked state with a fixed object (such as a cabinet body), completing automatic unlocking.

[0122] In this embodiment, the above input module 401 is adopted to trigger the unlocking instruction, and the driving motor 403 is controlled through the unlocking instruction, thereby realizing automatic unlocking, which is more convenient to use.

[0123] Refer to Figures 7 to 11 As shown, in an embodiment of the present invention, the inner lock body 20 includes a lock housing, a lock tongue 203, a transmission assembly 204 and a detection circuit board 204d. The lock tongue 203 is slidably arranged in the lock housing.

[0124] The transmission assembly 204 is arranged in the lock housing, and the transmission assembly 204 is in transmission connection between the lock tongue 203 and the lock rod 30. The lock rod 30 drives the transmission assembly 204 to make the lock tongue 203 extend out of or retract into the lock housing. That is, the transmission assembly 204 is configured to drive the lock tongue 203 to extend out of or retract into the lock housing when the lock rod 30 rotates, so as to complete locking or unlocking.

[0125] The detection circuit board 204d is provided with a first switch member 204e for detecting the extended position of the lock tongue 203 and a second switch member 204f for detecting the retracted position of the lock tongue 203.

[0126] That is to say, the lock rod 30 is connected to the transmission assembly 204, and the transmission assembly 204 is connected to the lock tongue 203. When the drive motor 403 drives the lock rod 30 to rotate, the lock rod 30 can further drive the transmission assembly 204 to drive the lock tongue 203 to slide relative to the lock housing, thereby driving the lock tongue 203 to extend out of the lock housing to lock, or retract into the lock housing to unlock, and its structure is simple. In addition, when the lock tongue 203 extends, the first switch member 204e can be triggered, and when the lock tongue 203 retracts, the second switch member 204f can be triggered. The trigger signals of the first switch member 204e and the second switch member 204f can be sent to the control circuit board 402, and the control circuit board 402 can determine whether the inner lock body 20 is in the locked state or the unlocked state according to the trigger signals, so as to ensure reliable locking and unlocking.

[0127] Referring to Figure 2 and Figure 6 As shown, in some embodiments of the present invention, the adapter plate 11 is provided with a first conductive terminal 111, and the detection circuit board 204d is provided with a second conductive terminal 21 in contact electrical connection with the first conductive terminal 111.

[0128] When the outer handle 10 and the inner lock body 20 are installed on the object to be locked 50, the first conductive terminal 111 abuts against the second conductive terminal 21 to form an electrical connection.

[0129] That is to say, the adapter plate 11 is provided with a first conductive terminal 111 electrically connected to the control circuit board 402, and the detection circuit board 204d is provided with a second conductive terminal 21. Preferably, a part of the outer handle 10 passes through the mounting hole on the object to be locked 50 and extends into the inner side of the object to be locked 50, and the adapter plate 11 is provided on the part of the outer handle 10 extending into the inner side of the object to be locked 50. When installing the inner lock body 20, the second conductive terminal 21 on the inner lock body 20 is aligned with the first conductive terminal 111 on the inner side of the object to be locked 50 for installation, and then the second conductive terminal 21 can abut against the first conductive terminal 111 to form an electrical connection.

[0130] In the related art, when an automatic lock is installed, the inner lock body 20 and the outer handle 10 are connected by wires to achieve electrical connection between the outer handle 10 and the inner lock body 20. This way of connecting by wires is inconvenient to install. For example, it is difficult to install when the wire is too short, and when the wire is too long, the internal space of the lock is not large enough to accommodate the long wire. In addition, the wire will interfere with the stability of the transmission inside the lock, and the reliability of the lock is poor.

[0131] In this embodiment, a first conductive terminal 111 is provided on the adapter board 11, and a second conductive terminal 21 is provided on the detection circuit board 204d of the inner lock body 20. When the outer handle 10 and the inner lock body 20 are installed on the object to be locked 50, the first conductive terminal 111 abuts against the second conductive terminal 21 to form an electrical connection. In this way, the electrical connection between the inner lock body 20 and the outer handle 10 can be realized. This contact connection is convenient and simple to install, does not require wires, does not occupy space, does not interfere with the transmission, and has higher reliability.

[0132] Preferably, one of the first conductive terminal 111 and the second conductive terminal 21 is an elastic conductive terminal, so that the first conductive terminal 111 elastically abuts against the second conductive terminal 21. In this way, by using the elastic abutment between the first conductive terminal 111 and the second conductive terminal 21, good and reliable electrical contact can be ensured, and the stability and reliability of the lock can be improved.

[0133] In addition, the first conductive terminal 111 and the second conductive terminal 21 can adopt structures such as elastic sheets and conductive contacts to achieve elastic contact and ensure reliable and stable.

[0134] Refer to Figures 1 to 2 and Figure 6 As shown in the figure, in an embodiment of the present invention, the automatic lock further includes an adapter board 11. The adapter board 11 is adapted to be installed on the inner side of the object to be locked 50. The adapter board 11 is provided with a through hole H11a for the lock rod 30 to pass through. The adapter board 11 is electrically connected to the control circuit board 402 through a conductive component; the adapter board 11 is electrically connected to the detection circuit board 204d. Preferably, the adapter board 11 is a PCB circuit board.

[0135] During installation, align the through hole H11a on the adapter board 11 with the installation hole on the object to be locked 50, and then use fasteners such as screws to fix the adapter board 11 to the inner side of the object to be locked 50. Preferably, a threaded hole is provided on the outer handle 10, and the screw passes through the object to be locked 50 and is threadedly connected to the threaded hole on the outer handle 10. In this way, the adapter board 11 can be fixed to the inner side of the object to be locked 50, and the outer handle 10 can be fixed to the outer side of the object to be locked 50 at the same time, making the installation more convenient. After installing the adapter board 11, then fix the inner lock body 20 to the object to be locked 50 through fasteners, and make the detection circuit board 204d on the inner lock body 20 align and abut against the adapter board 11.

[0136] In this embodiment, the adapter board 11 can be fixedly installed on the inner side of the object to be locked 50. In this way, when installing the inner lock body 20, the detection circuit board 204d on the inner lock body 20 is easily abutted against the adapter board 11 to form an electrical connection, making the installation more convenient.

[0137] Refer to Figure 3 and Figure 6As shown, in an embodiment of the present invention, the conductive component includes a conductive stud 404 and a conductive screw 12. The conductive stud 404 is provided on the control circuit board 402 and is electrically connected to the control circuit board 402. The adapter board 11 is provided with a fixing hole H11b. After the conductive screw 12 passes through the fixing hole H11b, it is threadedly connected to the conductive stud 404.

[0138] That is to say, when the conductive screw 12 locks and fixes the adapter board 11 to the object to be locked 50, the conductive screw 12 is in electrical contact with the adapter board 11. At the same time, the conductive stud 404 is electrically connected to the control circuit board 402. After the conductive screw 12 is threadedly connected to the conductive stud 404, an electrical contact is formed between the conductive screw 12 and the conductive stud 404. In this way, the electrical connection between the adapter board 11 and the control circuit board 402 can be realized without using wires. After the installation is completed, electrical conduction can be achieved, the installation is convenient, and the electrical connection is reliable.

[0139] Refer to Figures 9 to 11 As shown, in some embodiments of the present invention, the inner lock body 20 further includes a detecting tongue 205, an elastic member 206, and a third switch member 207. The detecting tongue 205 is slidably connected inside the lock housing and is located on one side of the locking tongue 203. Two ends of the elastic member 206 are elastically abutted against the lock housing and the detecting tongue 205 respectively. The third switch member 207 is provided on the detection circuit board 204d and is located at the end of the retracting path of the detecting tongue 205. The detecting tongue 205 triggers the third switch member 207, and the driving assembly 40 drives the lock rod 30 to rotate. The lock rod 30 drives the transmission assembly 204 to rotate, so that the locking tongue 203 extends out of the lock housing.

[0140] Exemplarily, the detecting tongue 205 can be slidable between a first position and a second position. The first position is the extreme position where the detecting tongue 205 slides out of the lock housing, and the second position is the extreme position where the detecting tongue 205 slides into the lock housing. When the detecting tongue 205 is located at the first position, a part of the detecting tongue 205 extends out of the lock housing. When the object to be locked 50 is closed, the extended part of the detecting tongue 205 is pressed by a fixed object and slides to the second position, and triggers the third switch member 207.

[0141] That is to say, in the absence of other external forces, the elastic force provided by the elastic member 206 forces the tongue 205 to move towards the first position and keeps the tongue 205 in the first position, that is, a part of the tongue 205 extends outside the lock housing. Exemplarily, one end of the tongue 205 forms a spherical surface S205, and in the first position, the said one end of the tongue 205 extends outside the lock housing. When the object to be locked 50 is closed, for example, when the door body is closed, the said one end (the spherical surface S205 part) of the tongue 205 is squeezed by the door frame, causing the tongue 205 to move to the second position. At this time, the other end of the tongue 205 triggers the third switch member 207 inside the lock housing. When the tongue 205 leaves the second position again, the third switch member 207 can generate a trigger signal, and this trigger signal can be used as a judgment signal for the object to be locked 50 being closed. When the control circuit board 402 receives the trigger signal from the third switch member 207, it indicates that the object to be locked 50 is closed. At this time, the control circuit board 402 controls the driving motor 403 to work according to the trigger signal, and uses the driving motor 403 to drive the lock rod 30 to rotate in one direction, so that the locking tongue 203 extends to lock automatically. In this way, it can be ensured that the locking operation is only performed when the object to be locked 50 is completely closed (in place), avoiding the situation of false locking during locking or the locking tongue 203 being stuck due to misalignment.

[0142] Referring Figures 9 to 11 As shown, in some embodiments of the present invention, the transmission assembly 204 includes a sliding member 204a and a first gear 204b adapted to be detachably connected to the lock rod 30. Both ends of the first gear 204b are slidably connected to the lock housing. The sliding member 204a is slidably disposed in the lock housing and connected to the locking tongue 203. The sliding member 204a has a first rack portion 2041a meshing with the first gear 204b. The direction in which the first gear 204b slides relative to the lock housing is parallel to the direction in which the sliding member 204a slides relative to the lock housing. That is to say, the first gear 204b can pivot about its own axis and move relative to the lock housing along the sliding direction of the sliding member 204a.

[0143] That is to say, the first gear 204b is connected to the lock rod 30 on the outer handle 10. The first gear 204b is driven to rotate by the lock rod 30. Since the first gear 204b meshes with the first rack portion 2041a, the engagement between the first gear 204b and the first rack portion 2041a can be used to drive the sliding member 204a to slide. During the sliding process of the sliding member 204a, the locking tongue 203 can be driven to extend out of the lock housing or retract into the lock housing.

[0144] Exemplarily, the first gear 204b is provided with a socket hole, the cross-section of which is non-circular, and the cross-section of the lock rod 30 is non-circular and adapted to the socket hole, and can be inserted into the socket hole to form circumferential relative fixation. When the lock rod 30 rotates, the first gear 204b can be driven to rotate synchronously.

[0145] In addition, in the present application, the first gear 204b is movable relative to the lock housing, that is to say, during installation, relative movement can occur between the first gear 204b and the lock housing along the sliding direction of the sliding member 204a. When the first gear 204b is stationary, the lock housing can slide relative to the first gear 204b along the above-mentioned sliding direction, and when the lock housing is stationary, the first gear 204b can slide relative to the lock housing along the above-mentioned sliding direction. Therefore, during installation, the position of the lock can be adjusted to meet the installation requirements for different door edge distances.

[0146] It should be noted that in the related art, the gear in the inner lock body 20 and the lock housing are relatively fixed and immovable. Since the gear needs to be connected to the lock rod 30 on the outer handle 10, and the lock rod 30 is inserted into the installation hole on the door body, after the gear and the lock rod 30 are aligned and connected, the position of the lock housing is also fixed accordingly. Therefore, for this structure, to ensure the accurate installation position of the lock housing, the position of the installation hole on the door body needs to be precise.

[0147] In the present application, since relative movement is possible between the first gear 204b and the lock housing, after the first gear 204b is connected to the lock rod 30 on the outer handle 10, the position of the lock housing can be adjusted by moving the lock housing until the position of the lock housing meets the installation requirements. For example, the side of the lock tongue 203 on the lock housing is aligned with the edge of the door body, and then the lock housing can be fixed to the locked object 50 through fasteners such as screws. This installation method with adjustable lock housing position greatly improves the installation convenience.

[0148] It can be understood that during installation, it is also possible to first adjust the position of the lock housing to the required position, then disassemble the first gear 204b, and reinstall the first gear 204b to the position corresponding to the installation hole and keep it meshed with the first rack portion 2041a on the sliding member 204a. This installation method can also achieve adjustable installation.

[0149] Refer to Figure 9 As shown, in an embodiment of the present invention, the lock housing includes a box body 201 and a cover plate 202. The box body 201 is provided with a first sliding hole H20a; the cover plate 202 covers the box body 201, and the cover plate 202 is provided with a second sliding hole H20b. Both the first sliding hole H20a and the second sliding hole H20b extend along the sliding direction of the sliding member 204a; the two shaft ends of the first gear 204b are respectively slidably arranged in the first sliding hole H20a and the second sliding hole H20b.

[0150] That is to say, the axis of the first gear 204b is perpendicular to the lock housing. One shaft end of the first gear 204b is arranged in the first sliding hole H20a, and the other shaft end of the first gear 204b is arranged in the second sliding hole H20b. When the first gear 204b and the lock housing slide relative to each other along the sliding direction of the sliding member 204a, the two shaft ends of the first gear 204b slide in the first sliding hole H20a and the second sliding hole H20b respectively. In this way, by using the cooperation between the two shaft ends of the first gear 204b and the first sliding hole H20a and the second sliding hole H20b, when the first gear 204b is installed in the lock housing, it can pivot around its own axis and slide relative to the lock housing along the sliding direction of the sliding member 204a. Its structure is simple, the installation is reliable and stable, and it is also convenient for assembly.

[0151] Referring Figures 9 to 11 As shown, in an embodiment of the present invention, the transmission assembly 204 further includes a second gear 204c. The second gear 204c meshes with the first gear 204b. The second gear 204c can pivot around its own axis and is movable relative to the lock housing along the sliding direction of the sliding member 204a.

[0152] The sliding member 204a further has a second rack portion 2042a arranged in parallel with the first rack portion 2041a. The second rack portion 2042a meshes with the second gear 204c.

[0153] In this embodiment, the sliding member 204a is provided with the first rack portion 2041a and the second rack portion 2042a in parallel. The engaged first gear 204b and second gear 204c are arranged between the first rack portion 2041a and the second rack portion 2042a. Moreover, the first gear 204b meshes with the first rack portion 2041a, and the second gear 204c meshes with the second rack portion 2042a. In this way, when the first gear 204b is driven to rotate by the lock rod 30, while the first gear 204b drives the first rack portion 2041a to move, it also drives the second gear 204c to rotate, and then drives the second rack portion 2042a to move through the second gear 204c. Since the first rack and the second rack are arranged in parallel, the sliding member 204a can be evenly stressed, move more smoothly and reliably, prevent problems such as jamming, and ensure that the retraction and extension of the lock tongue 203 are more stable and reliable.

[0154] In addition, the second gear 204c can also be movable relative to the lock housing along the sliding direction of the sliding member 204a. In this way, during installation, the position can also be adjusted quickly and simply by keeping the first gear 204b and the second gear 204c stationary and moving the lock housing.

[0155] Exemplarily, the slider 204a is formed as a square box member. The first rack portion 2041a and the second rack portion 2042a are respectively provided on two opposite sides of the square box member. The first gear 204b and the second gear 204c are located between two opposite sides of the square box member. In this way, it is convenient for the parallel arrangement of the first rack portion 2041a and the second rack portion 2042a, and for the formation of the meshing relationship between the first gear 204b, the second gear 204c and the first rack portion 2041a, the second rack portion 2042a.

[0156] Referring Figures 9 to 10 As shown, in an embodiment of the present invention, a third sliding hole H21a is provided on the box body 201, and a fourth sliding hole H21b is provided on the cover plate 202. Both the third sliding hole H21a and the fourth sliding hole H21b extend along the sliding direction of the slider 204a. Two shaft ends of the second gear 204c are respectively slidably provided in the third sliding hole H21a and the fourth sliding hole H21b.

[0157] That is to say, the axis of the second gear 204c is perpendicular to the lock housing. One shaft end of the second gear 204c is provided in the third sliding hole H21a, and the other shaft end of the second gear 204c is provided in the fourth sliding hole H21b. When the second gear 204c and the lock housing slide relative to each other along the sliding direction of the slider 204a, the two shaft ends of the second gear 204c slide in the third sliding hole H21a and the fourth sliding hole H21b respectively. In this way, by using the cooperation between the two shaft ends of the second gear 204c and the third sliding hole H21a and the fourth sliding hole H21b, when the second gear 204c is installed in the lock housing, it can pivot around its own axis and can slide relative to the lock housing along the sliding direction of the slider 204a. Its structure is simple, the installation is reliable and stable, and it is convenient for assembly.

[0158] Referring Figures 1 to 2 and Figure 6 As shown, in an embodiment of the present invention, a positioning sliding groove 201a is provided on the lock housing. The length direction of the positioning sliding groove 201a is consistent with the sliding direction of the slider 204a. The adapter plate 11 is adjustably installed in the positioning sliding groove 201a, and the adjustment direction of the adapter plate 11 is consistent with the length direction of the positioning sliding groove 201a. Exemplarily, the length of the positioning sliding groove 201a is greater than the length of the adapter plate 11, so that the adapter plate 11 can slide relative to the lock housing along the sliding direction of the slider 204a in the positioning sliding groove 201a.

[0159] During installation, the outer handle 10 is fixed to the outer side of the door body. The locking rod 30 of the outer handle 10 penetrates into the installation hole. At the same time, the through hole H11a on the adapter plate 11 is aligned with the installation hole on the object to be locked 50, and then the adapter plate 11 is installed on the object to be locked 50 through the conductive screw 12. Then, the positioning chute 201a on the lock case is aligned with the adapter plate 11, so that the adapter plate 11 is located within the positioning chute 201a. After the first gear 204b is adjusted to correspond to the through hole H11a and the installation hole, the first gear 204b is connected to the locking rod 30. For example, the locking rod 30 penetrates into the socket hole on the first gear 204b to achieve circumferential fixation. Subsequently, by moving the lock case, the position of the lock case is adjusted so that the lock case reaches the desired position.

[0160] In this embodiment, during the process of adjusting the lock case, by utilizing the sliding fit between the adapter plate 11 and the positioning chute 201a, the lock case can slide along the sliding direction, and the adjustment is simpler. Moreover, by utilizing the positioning function of the adapter plate 11, the height position of the lock case can be quickly positioned, further improving the convenience of installation.

[0161] Refer to Figure 8 and Figure 11 As shown, in an embodiment of the present invention, a first positioning end portion 2041b is formed by extending one shaft end of the first gear 204b, and the first positioning end portion 2041b is rotatably connected to the through hole H11a.

[0162] A positioning hole H11c is provided on the adapter plate 11. A second positioning end portion 2041c is formed by extending one shaft end of the second gear 204c, and the second positioning end portion 2041c is rotatably connected to the positioning hole H11c.

[0163] That is to say, the diameter of the first positioning end portion 2041b is adapted to the diameter of the through hole H11a, and the diameter of the second positioning end portion 2041c is adapted to the diameter of the positioning hole H11c. After the adapter plate 11 is fixedly installed on the object to be locked 50 through the fastener, when installing the inner lock body 20, the first positioning end portion 2041b of the first gear 204b can be directly inserted into the through hole H11a, and the socket hole on the first gear 204b just plugs into the locking rod 30, while the second positioning end portion 2041c of the second gear 204c is inserted into the positioning hole H11c. In this way, the positions of the first gear 204b and the second gear 204c can be determined and fixed relative to the adapter plate 11, and then the position of the lock case can be moved and adjusted.

[0164] In this embodiment, through the positioning cooperation between the first positioning end portion 2041b and the through hole H11a, and the positioning cooperation between the second positioning end portion 2041c and the positioning hole H11c, it is convenient for the quick positioning and installation of the first gear 204b and the second gear 204c, improving the installation efficiency.

[0165] Preferably, the sliding member 204a is provided with a toggle portion 2043a. When the toggle portion 2043a triggers the first switch 204e, the sliding member 204a stops driving the lock tongue 203 to extend out of the lock housing. When the toggle portion 2043a triggers the second switch 204f, the sliding member 204a stops driving the lock tongue 203 to retract into the lock housing.

[0166] That is to say, by providing a toggle portion 2043a on the sliding member 204a, the toggle portion 2043a can touch the first switch member 204e or the second switch member 204f during the sliding process of the sliding member 204a, so as to determine the position of the lock tongue 203, thereby ensuring the reliability of determining the locked and unlocked states of the lock.

[0167] It is understandable that the first switch element 204e, the second switch element 204f, and the third switch element 207 can be a touch switch, a photoelectric switch, or the like.

[0168] The lock cabinet according to the embodiment of the present invention has the automatic lock as described above. It is understandable that the outer handle 10 can be installed on the cabinet door, and the inner lock body 20 can be installed on the cabinet body.

[0169] The lock cabinet provided according to the embodiment of the present invention has the above-mentioned automatic lock, and the driving component 40 and the power supply component 13 are arranged in the outer handle 10. In the locked state, if the power supply component 13 lacks power and cannot be unlocked, the power supply component 13 can be replaced to achieve unlocking, which is more convenient to use and prevents the problem of difficulty in unlocking due to lack of power of the power supply component 13 caused by setting the power supply component 13 in the inner lock body 20.
