Description

Technical Field

[0001] The present invention relates to the technical field of intelligent electronic locks, and particularly to an anti-prying lock body housing for an intelligent electronic anti-theft lock. Background Art

[0002] The anti-prying lock housing mainly functions to install and protect the internal lock core. Nowadays, people's awareness of prevention is gradually increasing, and the protection of household property is also gradually enhanced. For existing theft techniques, people generally choose doors with anti-theft functions and anti-prying locks. The anti-prying lock has improved the drawback that ordinary door locks are easily pried open, and instead uses a password lock, greatly reducing the risk of being pried.

[0003] In order to deal with the failure of the electronic system, the password lock door generally retains a mechanical lock hole to prevent the owner from being locked outside the door. However, most of the existing mechanical lock holes are fixedly arranged, enabling some lawless elements to insert tools into the internal mechanical lock hole to drive the rotation of the mechanical lock hole, thereby opening the password lock door and causing economic losses and personal safety risks to the owner. Summary of the Invention

[0004] The purpose of the present invention is to provide an anti-prying lock body housing for an intelligent electronic anti-theft lock to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An anti-prying lock body housing for an intelligent electronic anti-theft lock, including a door body. On both the inner and outer sides of the door body, a password lock is installed. The password lock is composed of an outer body and an inner body. On the surface of the outer body, a password screen for unlocking the door body is provided. Above the password screen, a camera for monitoring the outside of the door body is installed. Below the password screen, a mechanical lock hole and an alarm are provided. On the outer surface of the inner body, a battery box is provided. On the outer surface of the inner body, a monitoring display screen connected to the camera is installed. Inside the inner body, a controller electrically connected to the battery box is fixedly connected. Inside the inner body, an elastic component for opening and closing a through hole is provided. On the inner side of the inner body, a linkage component for driving the mechanical lock hole to slide into the door body is provided.

[0006] Through the above technical solution, a password lock connected by a locking component is installed on both the inner and outer sides of the door body. The password screen provided on the surface of the outer body of the password lock is used for the owner to input the correct password to unlock the door body. When the correct password is input, the controller fixedly connected to the inner side of the inner body drives the first small servo motor fixedly connected to the inner side of the inner body to rotate, causing the rotating column at the output end of the first small servo motor to drive the transmission gear to rotate, and causing the lock tongue to move towards the inside of the door body to achieve unlocking.

[0007] When an outsider enters the wrong password multiple times, the alarm will send a message to the owner while driving the mechanical lock hole below the password screen to slide and contract inside the through hole. When the mechanical lock hole is completely inside the door body, the elastic component inside the receiving groove closes the through hole, which can prevent criminals from unlocking or disassembling the mechanical lock hole with professional unlocking tools, causing economic losses and personal safety risks to the owner.

[0008] As a further solution of the present invention, the outer body and the inner body are connected by a locking component. The locking component includes a connecting block installed inside the door body and a connecting rod penetrating the door body. A sliding column is slidably connected inside the connecting block. The sliding column is provided with a circumferentially arranged limiting hole. A limiting ball is rollingly embedded inside the limiting hole. A first slider is slidably connected to the inner side wall of the sliding column. The sliding column and the limiting ball are both made of metal material. The connecting rod slidably penetrates through the middle of the first slider.

[0009] As a further solution of the present invention, a plurality of concave regions are symmetrically arranged on the outer side of the connecting rod. The concave regions are in contact with the limiting balls. A compression spring is fixedly connected to the side of the first slider away from the limiting ball. The other end of the compression spring is fixedly connected to the inner top end of the connecting block.

[0010] Through the above technical solution, the concave regions arranged on the outer side of the connecting rod in the locking component can be engaged with the limiting balls rollingly embedded inside the limiting holes. Even if the outer part of the password lock is violently removed outward by criminals, the limiting balls will only be stuck tighter and tighter inside the limiting holes. Only at the corresponding position on the outer surface of the outer body, a strong magnet is used to attract the sliding column and the limiting balls made of metal material, so that the limiting balls and the sliding column drive the first slider to move towards the outer surface of the outer body. At this time, the limiting balls inside the limiting holes roll from the concave regions of the connecting rod to the flat parts. Due to the inclined arrangement of the inner side wall of the connecting block, the gap between the limiting holes and the inner side wall of the connecting block becomes larger and larger until it is larger than the diameter of the limiting balls, and through the contact of the flat part of the connecting rod, the limitation of the limiting balls is released until the first slider slides out of the connecting rod, realizing the disassembly of the outer body and the inner body of the password lock.

[0011] As a further solution of the present invention, a lock tongue is arranged on one side of the door body. A first small servo motor is fixedly connected to the inner side of the inner body. The output end of the first small servo motor is fixedly connected to a rotating column. A transmission gear for driving the lock tongue to move horizontally is fixedly connected to the top end of the rotating column. A central shaft is rotatably connected to the middle part of the inner side of the inner body. A driven gear meshing with the transmission gear is fixedly connected to the outer side of the central shaft. A sliding rail is fixedly connected to the top end of the lock tongue. A second slider connected to the central shaft is slidably connected inside the sliding rail.

[0012] As a further solution of the present invention, an opening is provided on the outer side of the slide rail close to the central axis. A rotating plate is fixedly connected to the outer side of the central axis. The end of the rotating plate is fixedly connected to the second slider, and the rotating plate rotates inside the opening.

[0013] Through the above technical solution, when the owner inputs the correct password to drive the transmission gear to rotate, since the driven gear fixedly connected to the outer side of the central axis meshes with the transmission gear, the driven gear follows the transmission gear to rotate, causing the central axis to rotate in the middle of the inner side of the outer body. At the same time, the rotating plate fixedly connected to the central axis rotates synchronously in the opening provided on the slide rail, and drives the second slider to slide in the arc-shaped slide rail, causing the lock tongue to move towards the inside of the door body to achieve unlocking.

[0014] As a further solution of the present invention, the end of the mechanical lock hole extends between the inner and outer sides of the door body. The linkage assembly includes a first support frame and a pair of second support frames fixedly connected to the inner side of the outer body. A second small servo motor is fixedly connected to the end of the first support frame. An output shaft is fixedly connected to the output end of the second small servo motor. A driving gear is fixedly connected to the end of the output shaft. The pair of second support frames are symmetrically arranged on both sides of the vertical center of the mechanical lock hole. A rotating shaft is rotatably connected to the middle of the second support frame. Straight gears are fixedly connected to both ends of the rotating shaft. The straight gear at one end of the rotating shaft meshes with the driving gear. Straight racks are symmetrically fixedly connected to the outside of the mechanical lock hole. The straight racks mesh with the straight gear at the other end of the rotating shaft.

[0015] Through the above technical solution, when the second small servo motor fixedly connected to the top of the first support frame is turned on, it will first drive the output shaft fixedly connected to the output end to drive the driving gear to rotate. Since a rotating shaft is rotatably connected to a pair of second support frames symmetrically arranged on both outer sides of the vertical center of the mechanical lock core, and the straight gear at one end of the rotating shaft meshes with the driving gear, a pair of rotating shafts synchronously follow the output shaft to rotate. The rotation of the pair of rotating shafts can cause the straight gears fixedly connected to the other ends to mesh with the straight racks symmetrically fixedly connected to the outside of the mechanical lock hole, causing the mechanical lock hole to slide towards the inside of the door body in the through hole.

[0016] As a further solution of the present invention, a pair of short columns are respectively fixedly connected to both ends of the straight rack. A ring block is slidably connected to the outside of the pair of short columns. A meshing tooth identical to the straight rack is fixedly connected to the top of the ring block. A first return spring is fixedly connected between the ring block and the end of the straight rack. The return spring is located outside the short column.

[0017] Through the above technical scheme, a pair of short columns arranged at both ends of the spur rack are slidably connected to the outer side with a ring block, and meshing teeth consistent with the spur rack are fixed to the top of the ring block, and reset and rebound are performed by the first reset spring between the ring block and the two ends of the spur rack, which can avoid the wear caused by the spur gear continuously driving the spur rack to move, and the second small servo motor being overloaded and damaged.

[0018] As a further solution of the present invention, an annular tooth is fixed to the outer side of the end of the mechanical lock hole, a telescopic rod is fixed between the inner side of the annular tooth and the inner side of the inner body, and an arc plate is meshingly connected to the outer side of the annular tooth; the arc plate is fixed to the outer side of the central axis, and the arc plate is located below the driven gear.

[0019] Through the above technical solution, when the owner needs to insert the key into the mechanical lock hole to unlock it, the annular tooth fixed at the end of the mechanical lock hole will rotate with the rotation of the mechanical lock hole, so that the arc plate meshing with the annular tooth will rotate accordingly. Since the arc plate is fixed to the outside of the central axis, the central axis can rotate synchronously to achieve unlocking.

[0020] As a further scheme of the present invention, a through hole is provided on the outer body, the mechanical lock hole is slidably arranged inside the through hole, and a groove is symmetrically provided inside the outer body with the center of the through hole as the axis. The elastic component includes a second return spring fixedly connected to the top and bottom ends of a pair of grooves, a round block is slidably connected inside the groove, and the other end of the second return spring is fixed to the round block, a telescopic column is fixedly connected to the middle part of the side of the round block close to the second return spring, the telescopic column is fixedly connected to the groove, and the groove is located inside the second return spring, and a trapezoidal protrusion is fixedly connected to the side of the round block away from the second return spring.

[0021] Through the above technical solution, when the mechanical lock hole moves toward the inside of the door body and the outer side of the mechanical lock hole releases the limit on the trapezoidal protrusion inside the receiving groove, due to the elasticity of the second return spring, the compressed second return spring will instantly drive a pair of protrusions to move toward each other in the direction of the through hole. During the movement, the telescopic column located inside the second return spring will fully extend to support the protrusion. At this time, the round block sliding inside the receiving groove will also move with the protrusion until the pair of protrusions collide to close the through hole, thereby preventing criminals from using professional tools to reach into the mechanical lock hole for prying or disassembly.

[0022] As a further solution of the present invention, the password screen, camera, alarm, monitoring display screen, first small servo motor and second small servo motor are all electrically connected to the controller.

[0023] The beneficial effects of the present invention are:

[0024] 1. The present invention installs a password lock connected by a locking component on both the inside and outside of the door body. By the owner entering the correct password on the password screen set on the outer surface of the password lock, the controller fixedly connected to the inner side of the inner body drives the first small servo motor to rotate. The output end of the first small servo motor drives the rotating column and the transmission gear to rotate synchronously, causing the lock tongue to move towards the inside of the door body to achieve unlocking.

[0025] 2. With the alarm of the present invention, when an outsider enters the wrong password multiple times, on the one hand, it will send a message to the owner, and on the other hand, the controller will activate the second small servo motor to drive the output shaft fixedly connected to the output end to drive the driving gear to rotate. At this time, the rotating shaft rotatably connected to the second support frame will drive the spur gear fixedly connected to the other end to engage with the rack, so that the mechanical lock hole can slide towards the inside of the door body within the through hole. When the mechanical lock hole moves towards the inside of the door body and releases the limit on the trapezoidal protrusion inside the receiving groove, due to the elasticity of the second return spring, the compressed second return spring will instantly drive a pair of protrusions to move towards each other in the direction of the through hole to close the through hole, which can prevent criminals from using professional tools to pry or disassemble by inserting them into the mechanical lock hole.

[0026] 3. With the setting of the annular teeth in the present invention, when the owner forgets the password or the house loses power and needs to use a key to insert into the mechanical lock hole for unlocking, the annular teeth fixedly connected to the end of the mechanical lock hole away from the lock hole will rotate following the rotation of the mechanical lock hole, causing the arc-shaped plate engaged with the annular teeth to rotate. Since the arc-shaped plate is fixedly connected to the outside of the central shaft, the central shaft can rotate synchronously to achieve unlocking.

[0027] 4. With the setting of the concave area on the outer side of the connecting rod in the locking component of the present invention, it can be engaged with the limiting balls rolling and embedded in the limiting holes. Even if the outer part of the password lock body is violently removed by criminals towards the outside, the limiting balls will only be stuck tighter and tighter in the limiting holes. Only at the corresponding position on the inner body surface and the connecting block, a strong magnetic block is used to attract the sliding column and the limiting balls made of metal material, so that the limiting balls and the sliding column drive the first slider to move towards the inner body surface direction to release the resistance of the limiting balls and achieve the disassembly of the password lock body and the inner body.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to Figures 1 to 10, the present invention provides a technical solution: an anti-prying lock body housing for an intelligent electronic anti-theft lock, including a door body 1, a password lock is installed on both the inner and outer sides of the door body 1. The password lock is composed of an outer body 2 and an inner body 3. A password screen 4 for unlocking the door body 1 is provided on the surface of the outer body 2. Above the password screen 4, a camera 5 for monitoring the outside of the door body 1 is installed. Below the password screen 4, a mechanical lock hole 6 and an alarm 7 are provided. A battery box 8 is provided on the outer surface of the inner body. A monitoring display screen 16 connected to the camera 5 is installed on the outer surface of the inner body 3. A controller 9 electrically connected to the battery box 8 is fixedly connected to the inner side of the inner body 3. An elastic component for opening and closing a through hole 10 is provided inside the inner body 3. A linkage component for driving the mechanical lock hole 6 to slide into the door body 1 is provided on the inner side of the inner body 3.

[0041] By installing a password lock connected by a locking component on both the inner and outer sides of the door body 1, the password screen 4 provided on the surface of the outer body 2 of the password lock is used for the owner to input the correct password to unlock the door body 1. When the correct password is input, the controller 9 fixedly connected to the inner side of the inner body 3 drives the first small servo motor 13 fixedly connected to the inner side of the inner body 3 to rotate, so that the rotating column 14 at the output end of the first small servo motor 13 drives the transmission gear 15 to rotate, and the lock tongue 12 moves towards the inside of the door body 1. The transmission gear 15 meshes with the driven gear 25 on the outside of the central shaft 24, so that the driven gear 25 can drive the lock tongue 12 to move to achieve unlocking;

[0042] When an outsider enters the wrong password multiple times, the password screen 4 will transmit the wrong input information to the controller 9. At this time, the controller 9 will turn on the alarm 7 and send this information to the owner's mobile phone. At the same time, the controller 9 will turn on the second small servo motor 32 to drive the mechanical lock hole 6 below the password screen 4 to slide and contract into the through hole 10 until the mechanical lock hole 6 is completely inside the door body 1. The elastic component in the receiving groove 11 closes the through hole 10, which can prevent criminals from unlocking or disassembling the mechanical lock hole 6 with professional unlocking tools, causing economic losses and personal safety risks to the owner.

[0043] Please refer to Figure 2 , the outer body 2 and the inner body 3 are connected by a locking component. The locking component includes a connecting block 17 installed inside the door body 1 and a connecting rod 18 penetrating the door body 1. A sliding column 19 is slidably connected inside the connecting block 17. A circumferentially arranged limiting hole 20 is provided on the sliding column 19. A limiting ball 21 is rollingly embedded inside the limiting hole 20. A first slider 22 is slidably connected to the inner side wall of the sliding column 19. Both the sliding column 19 and the limiting ball 21 are made of metal materials. The connecting rod 18 slidably penetrates the middle of the first slider 22. A plurality of concave regions are symmetrically arranged on the outside of the connecting rod 18, and the concave regions are in contact with the limiting balls 21. A compression spring 23 is fixedly connected to the side of the first slider 22 away from the limiting ball 21, and the other end of the compression spring 23 is fixedly connected to the inner top end of the connecting block 17.

[0044] It is set through the recessed area on the outer side of the connecting rod 18 in the locking component, and can be engaged with the limiting ball 21 that is rolling and embedded inside the limiting hole 20. Even if the outer body 2 of the password lock is violently removed externally by lawbreakers, the limiting ball 21 will only be stuck tighter and tighter inside the limiting hole 20. Only at the corresponding position on the surface of the inner body 3 and the connecting block 17, a strong magnet is used to attract the sliding column 19 and the limiting ball 21 made of metal material, so that the limiting ball 21 and the sliding column 19 drive the first slider 22 to move towards the surface of the outer body 2. At this time, the limiting ball 21 inside the limiting hole 20 rolls from the recessed area of the connecting rod 18 to the flat part. Due to the inclined setting of the inner side wall of the connecting block 17, the gap between the limiting hole 20 and the inner side wall of the connecting block 17 becomes larger and larger until it is larger than the diameter of the limiting ball 21, and through the contact of the flat part of the connecting rod 18, the limit of the limiting ball 21 is released until the first slider 22 slides out of the connecting rod 18, realizing the replacement of the password lock.

[0045] Please refer to Figures 3 to 5 As shown in, a lock tongue 12 is provided on one side of the door body 1. A first small servo motor 13 is fixedly connected to the inner side of the inner body 3. The output end of the first small servo motor 13 is fixedly connected to a rotating column 14. The top end of the rotating column 14 is fixedly connected to a transmission gear 15 for driving the lock tongue 12 to move horizontally. The middle part of the inner side of the outer body 2 is rotatably connected to a central shaft 24. A driven gear 25 meshing with the transmission gear 15 is fixedly connected to the outer side of the central shaft 24. The top end of the lock tongue 12 is fixedly connected to a slide rail 26. A second slider 27 connected to the central shaft 24 is slidably connected inside the slide rail 26. An opening 28 is opened on the outer side of the slide rail 26 close to the central shaft 24. A rotating plate 29 is fixedly connected to the outer side of the central shaft 24. The end of the rotating plate 29 is fixedly connected to the second slider 27, and the rotating plate 29 rotates inside the opening 28.

[0046] When the owner inputs the correct password to drive the transmission gear 15 to rotate, because the driven gear 25 fixedly connected to the outer side of the central shaft 24 meshes with the transmission gear 15, the driven gear 25 follows the transmission gear 15 to rotate, so that the central shaft 24 rotates in the middle part of the inner side of the inner body 3. At the same time, the rotating plate 29 fixedly connected to the central shaft 24 rotates synchronously inside the opening 28 opened in the slide rail 26, and drives the second slider 27 to slide in the arc-shaped slide rail 26, so that the lock tongue 12 moves towards the inside of the door body 1 to realize unlocking.

[0047] Please refer to Figure 4 and Figure 6, the end of the mechanical keyhole 6 extends between the inner and outer sides of the door body 1. The linkage assembly includes a first support frame 30 fixedly connected to the inner side of the inner body 3 and a pair of second support frames 31. The end of the first support frame 30 is fixedly connected with a second small servo motor 32. The output end of the second small servo motor 32 is fixedly connected with an output shaft 33. The end of the output shaft 33 is fixedly connected with a driving gear 34. The pair of second support frames 31 are symmetrically arranged on both sides of the vertical center of the mechanical keyhole 6. The middle of the second support frame 31 is rotatably connected with a rotating shaft 35. Both ends of the rotating shaft 35 are fixedly connected with spur gears 36. The spur gear 36 at one end of the rotating shaft 35 meshes with the driving gear 34. The outer side of the mechanical keyhole 6 is symmetrically fixedly connected with straight racks 37. The straight racks 37 mesh with the spur gears 36 at the other end of the rotating shaft 35.

[0048] When the second small servo motor 32 fixedly connected to the top of the first support frame 30 is turned on, it will first drive the output shaft 33 fixedly connected to the output end to rotate. The rotation of the output shaft 33 drives the driving gear 34 to rotate. Since the rotating shafts 35 are rotatably connected to both of the pair of second support frames 31 symmetrically arranged on the two outer sides of the vertical center of the mechanical lock core, and the spur gear 36 at one end of the rotating shaft 35 meshes with the driving gear 34, the pair of rotating shafts 35 synchronously rotate following the output shaft 33. When the pair of rotating shafts 35 rotate, they drive the two spur gears 36 thereon to rotate synchronously, enabling the spur gears 36 fixedly connected to the other end to mesh with the straight racks 37 symmetrically fixedly connected to the outer side of the mechanical keyhole 6, so that the mechanical keyhole 6 can slide inward in the direction of the door body 1 and be received into the through hole 10.

[0049] While the mechanical keyhole 6 is moving, the telescopic rod located between the annular tooth 42 and the inner side of the outer body 2 will extend synchronously to support the mechanical keyhole 6.

[0050] Please refer to Figure 7 , both ends of the straight rack 37 are respectively fixedly connected with a pair of short columns 38. The outer sides of the pair of short columns 38 are slidably connected with a ring block 39. The top of the ring block 39 is fixedly connected with a meshing tooth 40 identical to the straight rack 37. A first return spring 41 is fixedly connected between the ring block 39 and the end of the straight rack 37. The return spring is located outside the short column 38.

[0051] By slidably connecting a ring block 39 to the outer sides of the pair of short columns 38 provided at both ends of the straight rack 37, fixedly connecting a meshing tooth 40 identical to the straight rack 37 to the top of the ring block 39, and performing a return springback through the first return spring 41 between both ends of the ring block 39 and the straight rack 37, it is possible to avoid the wear caused by the continuous driving of the straight rack 37 by the spur gear 36 and the overload of the second small servo motor 32, thereby preventing damage.

[0052] Please refer to Figure 3 , Figures 7 to 9, an annular tooth 42 is fixedly connected to the outer side of the end of the mechanical keyhole 6. A telescopic rod 43 is fixedly connected between the inner side of the annular tooth 42 and the inner side of the inner body 3. The outer side of the annular tooth 42 is meshed and connected with an arc-shaped plate 44; the arc-shaped plate 44 is fixedly connected to the outer side of the central shaft 24 and is located below the driven gear 25.

[0053] When the owner needs to insert a key into the mechanical keyhole 6 for unlocking, the annular tooth 42 fixedly connected to the end of the mechanical keyhole 6 away from the keyhole will rotate following the rotation of the mechanical keyhole 6, causing the arc-shaped plate 44 meshed with the annular tooth 42 to rotate. Since the arc-shaped plate 44 is fixedly connected to the outer side of the central shaft 24, the central shaft 24 can rotate synchronously to achieve unlocking.

[0054] Please refer to Figure 8 and Figure 9 , a through hole 10 is formed in the outer body 2. The mechanical keyhole 6 is slidably arranged inside the through hole 10. Inside the outer body 2, a receiving groove 11 is symmetrically formed with the center of the through hole 10 as the axis. The elastic component includes a second return spring 45 fixedly connected inside the receiving groove 11. A round block 46 is slidably connected inside the receiving groove 11. The other end of the second return spring 45 is fixedly connected to the round block 46. In the middle of the side of the round block 46 close to the second return spring 45, a telescopic column 47 is fixedly connected. The telescopic column 47 is fixedly connected inside the receiving groove 11, and the receiving groove 11 is located inside the second return spring 45. A trapezoidal convex block 48 is fixedly connected to the side of the round block 46 away from the second return spring 45.

[0055] In the initial state, the convex block 48 inside the receiving groove 11 abuts against the outside of the mechanical keyhole, and the second return spring 45 inside the receiving groove 11 is in a compressed state;

[0056] When the mechanical keyhole 6 moves towards the inside of the door body 1 until the outside of the mechanical keyhole 6 disengages from the abutment with the convex block 48, due to the elasticity of the second return spring 45, the second return spring 45 in a compressed state inside the receiving groove 11 will instantly drive a pair of convex blocks 48 to move towards each other in the direction of the through hole 10 until the pair of convex blocks 48 abut against each other to close the through hole 10, which can prevent criminals from using professional tools to reach into the mechanical keyhole 6 for unlocking;

[0057] While moving, the output end of the telescopic column 47 will fully extend to support the convex block 48. At this time, the round block 46 fixedly connected to the output end of the telescopic column 47 slides on the inner side wall of the receiving groove 11 and moves synchronously with the convex block 48.

[0058] Please refer to Figure 1 and Figure 10 , the password screen 4, the camera 5, the alarm 7, the monitoring display screen 16, the first small servo motor 13 and the second small servo motor 32 are all electrically connected to the controller 9.

[0059] Working principle:

[0060] During installation, first install the inner body 3 of the password lock on the inner side of the door body 1, then align the connecting block 17 on the outer body 2 of the password lock with the connecting rod 18 on the inner body 3, and then install the outer body 2 of the password lock on the outer side of the door body 1;

[0061] Input the password on the password screen 4, and the controller 9 determines whether the password is correct to correspondingly activate the first small servo motor 13 and the second small servo motor 32. The monitoring display screen 16 can see the situation outside the door body 1 through the camera 5;

[0062] When the connecting rod 18 is connected to the inside of the connecting block 17, the top of the connecting rod 18 first inserts into the middle of the first slider 22 until the limiting ball 21 in the limiting hole 20 opened on the sliding column 19 engages with the concave area on the outer side of the connecting rod 18. Even if the outer body 2 of the password lock is violently removed externally by lawbreakers, the limiting ball 21 will only get stuck tighter and tighter inside the limiting hole 20;

[0063] When it is necessary to separate the connecting block 17 and the connecting rod 18, just use a strong magnetic block to absorb the sliding column 19 and the limiting ball 21 made of metal material at the corresponding position on the surface of the inner body 3 and the connecting block 17, so that the limiting ball 21 and the sliding column 19 drive the first slider 22 to move towards the surface of the inner body 3. While moving, the first slider 22 will drive the compression spring 23 to be compressed. At this time, the limiting ball 21 inside the limiting hole 20 rolls from the concave area of the connecting rod 18 to the flat part. Due to the inclined setting of the inner side wall of the connecting block 17, the gap between the limiting hole 20 and the inner side wall of the connecting block 17 becomes larger and larger until it is larger than the diameter of the limiting ball 21, and through the contact of the flat part of the connecting rod 18, the limitation of the limiting ball 21 is released until the first slider 22 slides out of the connecting rod 18;

[0064] When the owner inputs the correct password on the password screen 4, the controller 9 fixedly connected to the inner side of the inner body 3 drives the first small servo motor 13 fixedly connected to the inner side of the inner body 3 to rotate, so that the rotating column 14 at the output end of the first small servo motor 13 drives the transmission gear 15 to rotate. Since the driven gear 25 fixedly connected to the outside of the central shaft 24 meshes with the transmission gear 15, the driven gear 25 rotates following the transmission gear 15, so that the central shaft 24 rotates in the middle of the inner side of the inner body 3. At the same time, the rotating plate 29 fixedly connected to the central shaft 24 rotates synchronously in the opening 28 opened on the slide rail 26 and drives the second slider 27 to slide in the arc-shaped slide rail 26, so that the lock tongue 12 moves towards the inside of the door body 1 to achieve unlocking;

[0065] When an outsider enters the wrong password multiple times, on one hand, a message will be sent to the owner, and on the other hand, the second small servo motor 32 will be activated through the controller 9 to drive the output shaft 33 fixedly connected to the output end to drive the driving gear 34 to rotate. At this time, the rotating shaft 35 rotatably connected to the second support frame 31 will drive the spur gear 36 fixedly connected to the other end to mesh with the rack 37, so that the mechanical lock hole 6 can slide inward into the door body 1 in the through hole 10. While the mechanical lock hole 6 moves, the telescopic rod between the annular tooth 42 and the inner body 3 will be compressed synchronously to support the mechanical lock hole 6;

[0066] A ring block 39 is slidably connected to the outside of a pair of short columns 38 provided at both ends of the rack 37, and a meshing tooth 40 identical to the rack 37 is fixedly connected to the top of the ring block 39, and is reset and rebounded by the first return spring 41 between the ring block 39 and both ends of the rack 37, which can avoid the wear caused by the spur gear 36 continuously driving the rack 37 to move, and prevent the second small servo motor 32 from being overloaded and damaged;

[0067] In the initial state, the convex block 48 inside the receiving groove 11 abuts against the outside of the mechanical lock hole, and the second return spring 45 inside the receiving groove 11 is in a compressed state;

[0068] When the mechanical lock hole 6 moves inward into the door body 1 until the outside of the mechanical lock hole 6 disengages from the abutment with the convex block 48, due to the elasticity of the second return spring 45, the second return spring 45 in a compressed state inside the receiving groove 11 at this time will instantly drive a pair of convex blocks 48 to move towards each other in the direction of the through hole 10 until the pair of convex blocks 48 abut against each other to close the through hole 10, which can prevent criminals from using professional tools to reach into the mechanical lock hole 6 for unlocking;

[0069] While moving, the output end of the telescopic column 47 will fully extend to support the convex block 48. At this time, the round block 46 fixedly connected to the output end of the telescopic column 47 slides on the inner side wall of the receiving groove 11 and moves synchronously with the convex block 48;

[0070] When the owner forgets the password and needs to insert a key into the mechanical lock hole 6 for unlocking, the annular tooth 42 fixedly connected to the end of the mechanical lock hole 6 away from the lock hole will rotate following the rotation of the mechanical lock hole 6, so that the arc-shaped plate 44 meshing with the annular tooth 42 rotates. Since the arc-shaped plate 44 is fixedly connected to the outside of the central shaft 24, the central shaft 24 can rotate synchronously to achieve unlocking.

[0071] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
