Description

Technical Field

[0001] The present invention relates to the technical field of door locks, and in particular to an anti-theft lock. Background Art

[0002] The anti-theft locks provided by related technologies include mechanical locks and smart locks. Among them, the smart lock is a new type of door lock that can be unlocked using passwords, fingerprints, and face recognition. Since keys do not need to be carried in daily use, it is more convenient to use and is less likely to cause problems such as being unable to unlock or open the door due to users forgetting to carry keys.

[0003] Smart locks require battery power to unlock using methods such as passwords, fingerprints, and facial recognition. If the battery dies or an error occurs during smart unlocking, a mechanical key is still required. However, users typically don't carry mechanical keys with them when they're out, preventing them from unlocking their smart locks. To address this issue, related technologies have hidden mechanical keys inside the anti-theft lock body. When the mechanical key is needed, the key can be removed from the lock body to unlock the lock.

[0004] However, this method greatly reduces security, and criminals can easily remove the key from the lock body to unlock it. Summary of the Invention

[0059] Please refer to Figure 1 and Figure 2 The present embodiment provides an anti-theft lock 010, which includes a lock body 100, a lock core 110 and a lock tongue 120 assembled on the lock body 100, the lock tongue 120 being movably arranged on the lock body 100 and being able to extend or retract relative to the lock body 100, the lock core 110 and the lock tongue 120 being transmission-connected, and the lock core 110 being used to drive the lock tongue 120 to extend and retract relative to the lock body 100 to achieve locking and unlocking.

[0060] The structures and working principles of the lock body 100 , lock core 110 and lock tongue 120 are similar to those of door locks provided in the related art and will not be described in detail here.

[0061] Among them, the modes of controlling the lock core 110 to make the lock tongue 120 extend and retract include electric control mode and mechanical control, that is, the unlocking and locking methods of the anti-theft lock 010 include electric control mode and mechanical mode. The electric unlocking mode includes unlocking using fingerprint, password and face recognition, etc. The specific design of the electric control module and the working principle are similar to the relevant technology. The mechanical unlocking mode is to use a mechanical key to drive the lock core 110 to retract the lock tongue 120 into the lock body 100.

[0062] Please refer to Figure 1 、 Figure 2 and Figure 3The anti-theft lock 010 of this embodiment also includes a rotating mechanism 200, a key 300 and a locking mechanism 400. The rotating mechanism 200 can be movably assembled on the lock body 100, and the rotating mechanism 200 is configured to be able to be transmission-connected or disconnected with the lock cylinder 110; the key 300 cooperates with the rotating mechanism 200 in transmission, and the key 300 can drive the rotating mechanism 200 to be transmission-connected with the lock cylinder 110, and when the rotating mechanism 200 is transmission-connected with the lock cylinder 110, the key 300 can also drive the rotating mechanism 200 to rotate, so that the lock cylinder 110 drives the lock tongue 120 to retract the lock body 100 through the rotating mechanism 200; the locking mechanism 400 is assembled on the lock body 100, and is used to lock or unlock the key 300, wherein, when the locking mechanism 400 locks the key 300, the key 300 cannot drive the rotating mechanism 200 to rotate; when the locking mechanism 400 unlocks the key 300, the key 300 can drive the rotating mechanism 200 to rotate.

[0063] In this way, only when the locking mechanism 400 unlocks the key 300 can the key 300 be used to drive the rotating mechanism 200 to rotate, and the rotating mechanism 200 drives the lock core 110 to retract the lock tongue 120 into the lock body 100, thereby completing the unlocking of the anti-theft lock 010. When the locking mechanism 400 locks the key 300, even if the criminals get the key 300, they cannot use the key 300 to drive the rotating mechanism 200 to rotate and unlock, thereby improving security.

[0064] It should be understood that in other embodiments, the locking mechanism 400 can also be used to lock or unlock the rotating mechanism 200. When the locking mechanism 400 locks the rotating mechanism 200, the key 300 cannot drive the rotating mechanism 200 to rotate; when the locking mechanism 400 unlocks the rotating mechanism 200, the key 300 can drive the rotating mechanism 200 to rotate. Only when the locking mechanism 400 unlocks the rotating mechanism 200 can the key 300 be used to drive the rotating mechanism 200 to rotate, and the rotating mechanism 200 drives the lock cylinder 110 to rotate, so that the lock tongue 120 retracts into the lock body 100, completing the unlocking of the anti-theft lock 010. When the locking mechanism 400 locks the rotating mechanism 200, even if a criminal obtains the key 300, he cannot use the key 300 to drive the rotating mechanism 200 to rotate and unlock the lock, thereby improving security.

[0065] In other embodiments, the anti-theft lock 010 may only include a mechanically controlled unlocking method, that is, it can only be unlocked using the key 300, and cannot be unlocked using fingerprint, face recognition, etc., which is not specifically limited here.

[0066] Please refer to Figure 1 、 Figure 2 and Figure 3The structure of the lock body 100 is similar to that of the related art, and it includes a front shell 101 and a rear shell 102, wherein the front shell 101 is used to be assembled on the front side of the anti-theft door, that is, the outer side of the anti-theft door when it is closed, and the rear shell 102 is used to be assembled on the rear side of the anti-theft door, that is, the inner side of the anti-theft door when it is closed; the locking mechanism 400 is assembled on the front shell 101, and the key 300 can be extended from the front shell 101 to facilitate the user to unlock the door outdoors.

[0067] Furthermore, the front housing 101 includes an upper cover 103 and a bottom housing 104. The upper cover 103 and the bottom housing 104 are snap-fitted and connected. The bottom housing 104 is used to connect to the anti-theft door. The locking mechanism 400 is assembled on the bottom housing 104. The upper cover 103 is used to shield and protect the locking mechanism 400. The connection method between the upper cover 103 and the bottom housing 104 includes, but is not limited to, snap-fitting and welding.

[0068] Furthermore, the lock body 100 further includes an assembly shell 105 , and the lock tongue 120 , the lock core 110 and the rotating mechanism 200 are all assembled in the assembly shell 105 , and the assembly shell 105 is used to be assembled in the anti-theft door.

[0069] Please refer to Figure 4 、 Figure 5 and Figure 6 ( Figure 6 The first connecting member 220 is only connected to the first connecting shaft 210 in transmission connection, and is not connected to the lock core 110 in transmission connection). The rotating mechanism 200 of this embodiment includes the first connecting shaft 210 and the first connecting member 220. The two ends of the first connecting shaft 210 are respectively provided with a first plug hole 211 and a second plug hole 212. The first plug hole 211 is connected to the second plug hole 212. The key 300 can be slidably inserted into the first plug hole 211, and the first connecting member 220 can be slidably inserted into the second plug hole 212. The first connecting member 220 can be connected to or disconnected from the lock core 110 in transmission connection; when the key 300 slides axially along the first plug hole 211 under the action of external force, it can push the first connecting member 220 to slide relative to the first connecting shaft 210 in the second plug hole 212, and slide until it is connected to the lock core 110 and the first connecting shaft 210 at the same time (such as Figure 7 When the first connecting member 220 is simultaneously connected to the lock core 110 and the first connecting shaft 210, and the key 300 rotates around its own rotation axis under the action of an external force, it can drive the first connecting shaft 210 and the first connecting member 220 to rotate, and drive the lock core 110 through the first connecting member 220 to retract the lock tongue 120 into the lock body 100.

[0070] Furthermore, the lock core 110 is provided with a third plugging hole 112, specifically, the unlocking dial 111 of the lock core 110 is provided with a third plugging hole 112; the hole wall of the second plugging hole 212 is provided with a first sliding groove 213, and the hole wall of the third plugging hole 112 is provided with a second sliding groove 113, and the first connecting member 220 is connected with a first rib 221, and the first rib 221 can be slidably inserted into the first sliding groove 213, and the first rib 221 can be inserted into or separated from the second sliding groove 113; wherein, when the first rib 221 is simultaneously inserted into the first sliding groove 213 and the second sliding groove 113, the first connecting member 220 is simultaneously transmission-connected to the lock core 110 and the first connecting shaft 210; when the first rib 221 is separated from the second sliding groove 113, the transmission connection between the first connecting member 220 and the lock core 110 is disconnected. The provision of the first rib 221 can ensure the stability of the transmission connection between the first connecting member 220 and the first connecting shaft 210 , as well as the lock cylinder 110 , thereby ensuring the reliability of unlocking with the key 300 .

[0071] The number of the first slide groove 213, the second slide groove 113 and the first rib 221 can be selected as needed; in this embodiment, the first connecting member 220 is connected to two first ribs 221, and the two first ribs 221 are distributed at intervals along the circumference of the first connecting member 220; the hole wall of the second plug-in hole 212 is provided with two first slide grooves 213, and the hole wall of the third plug-in hole 112 is provided with two second slide grooves 113, the two first ribs 221 are plugged in one-to-one with the two first slide grooves 213, and the two first ribs 221 can be plugged in one-to-one with the two second slide grooves 113.

[0072] Of course, in other embodiments, the number of the first sliding groove 213, the second sliding groove 113 and the first rib 221 can also be one, three, etc., which is not specifically limited here.

[0073] The first insertion hole 211 and the end of the key 300 into which it is inserted are adapted in shape and size to enable the key 300 to slide smoothly within the first insertion hole 211 and reliably drive the first connecting shaft 210 to rotate synchronously. For example, the end of the key 300 inserted into the first insertion hole 211 and the first insertion hole 211 are both rectangular.

[0074] Since the first rib 221 needs to be opposite to the second slide groove 113, the first connector 220 can slide into the third insertion hole 112. Therefore, in order to ensure that the first connector 220 slides into the third insertion hole 112 and the first rib 221 can be plugged into the second slide groove 113 and the first slide groove 213 at the same time, the first connector 220 can be stably connected to the lock cylinder 110 and the first connecting shaft 210 at the same time. Figure 4 、 Figure 6 and Figure 7The rotating mechanism 200 also includes a pin 230 and a first elastic member 240. The pin 230 can be slidably inserted into the first connecting member 220. The first elastic member 240 is connected between the pin 230 and the first connecting member 220, and the key 300 can abut against the pin 230; when the key 300 slides along the axial direction of the first plug hole 211 under the action of external force, the key 300 abuts against the pin 230 so that the pin 230 slides relative to the first connecting member 220, and the pin 230 causes the first elastic member 240 to undergo elastic deformation. The first connecting member 220 can move under the elastic action of the first elastic member 240 to be transmission-connected to the lock cylinder 110 and the first connecting shaft 210 at the same time.

[0075] When the first rib 221 is opposite to the second slide groove 113, the key 300 slides along the axial direction of the first plug hole 211 under the action of external force and abuts against the pin 230 to push the pin 230 to move. The thrust exerted on the pin 230 is transmitted to the first connecting member 220 through the first elastic member 240, so that the first connecting member 220 can be moved to be plugged into the third plug hole 112, and the first rib 221 slides to be plugged into the second slide groove 113. When the first rib 221 is misaligned with the second slide groove 113 (completely not opposite or partially not opposite), the key 300 slides along the axial direction of the first plug hole 211 under the action of external force and abuts against the pin 230 to push the pin 230 to move. When the first rib 221 is rotated to face the second slide groove 113, the first link 220 slides into the third inserting hole 112 under the elastic action of the first elastic member 240, and the first rib 221 slides to be inserted into the second slide groove 113.

[0076] Alternatively, see Figure 4 、 Figure 6 and Figure 7The first connecting member 220 is provided with a first assembly hole 222, into which a pin 230 is slidably inserted. A first elastic member 240 is sleeved on the pin 230, with both ends of the first elastic member 240 connected to the wall of the first assembly hole 222 and the pin 230, respectively. When the key 300 pushes the pin 230, the pin 230 squeezes the first elastic member 240. When the first rib 221 faces the second slot 113, the first elastic member 240 extends under its own elastic action and pushes the first connecting member 220 into the third insertion hole 112. This arrangement achieves a compact structural design and ensures that the first elastic member 240 can reliably slide the first connecting member 220 into the third insertion hole 112.

[0077] It should be understood that in other embodiments, the first elastic member 240 is not sleeved on the pin 230, but only has two ends connected to the pin 230 and the first connecting member 220 respectively; when the pin 230 is pushed by the key 300, the pin 230 can stretch the first elastic member 240, and when the first rib 221 is opposite to the second slide groove 113, the first elastic member 240 retracts under its own elastic action and pushes the first connecting member 220 into the third plug hole 112.

[0078] The connection methods of the first elastic member 240 , the hole wall of the first assembly hole 222 , and the pin 230 include, but are not limited to, abutment, clamping, and bonding.

[0079] Please refer to Figure 4 、 Figure 6 and Figure 7 The anti-theft lock 010 of this embodiment further includes a second elastic member 500, a second connecting member 510 and a driving mechanism. The driving mechanism is provided with a fourth plug hole 523. For details, please refer to Figure 3 and Figure 4 The driving mechanism includes a motor 521 and a second connecting shaft 522. The motor 521 is assembled to the rear shell 102, and the second connecting shaft 522 is assembled to the assembly shell 105. The output shaft of the motor 521 is transmission-connected to the second connecting shaft 522. The second connecting shaft 522 is provided with a fourth plug hole 523. Please continue to refer to Figure 4 、 Figure 6 and Figure 7When the second connecting member 510 is separated from the third plug hole 112 and only plugged into the fourth plug hole 523, the transmission connection between the second connecting member 510 and the lock core 110 is disconnected; the second elastic member 500 is connected between the second connecting member 510 and the driving mechanism; the first connecting member 220 is further configured to drive the second connecting member 510 to slide in the fourth plug hole 523; when the first connecting member 220 slides When the key 300 is in transmission connection with both the lock cylinder 110 and the first connecting shaft 210, the first connecting member 220 drives the second connecting member 510 to slide until the transmission connection with the lock cylinder 110 is disconnected, that is, the first connecting member 220 drives the second connecting member 510 to slide out of the third insertion hole 112 and only plug into the fourth insertion hole 523. When the key 300 is not subjected to external force, the elastic action of the second elastic member 500 causes the second connecting member 510 to slide until the second connecting member 510 is in transmission connection with the drive mechanism and the lock cylinder 110, and the second connecting member 510 disconnects the transmission connection between the first connecting member 220 and the lock cylinder 110. At this time, the motor 521 can be used to drive the second connecting shaft 522 to rotate, and the second connecting member 510 drives the lock cylinder 110 to retract the lock tongue 120 into the lock body 100, thereby realizing electric unlocking. With this arrangement, the anti-theft door can be unlocked using both a mechanical key and a reliably electronically controlled unlocking using the motor 521.

[0080] Alternatively, see Figure 6 and Figure 7, the second connecting member 510 is provided with a second assembly hole 511, the second assembly hole 511 passes through the second connecting member 510, the first assembly hole 222 passes through the first connecting member 220, the pin 230 passes through the first assembly hole 222 and is plugged into the second assembly hole 511; the second elastic member 500 is sleeved on the end of the pin 230 away from the key 300, and the two ends of the second elastic member 500 are respectively connected to the second connecting member 510 and the hole wall of the fourth plugging hole 523; when the second connecting member 510 is pushed by the first connecting member 220, it is disengaged from the first When the third insertion hole 112 is only inserted into the fourth insertion hole 523, the second connector 510 squeezes the second elastic member 500, causing the second elastic member 500 to deform elastically. When the key 300 is no longer subjected to external force, the second elastic member 500 extends and returns to its original position under its own elastic action, pushing the second connector 510 back to the position where it is simultaneously inserted into the fourth insertion hole 523 and the third insertion hole 112, and causing the first connector 220 to no longer be inserted into the third insertion hole 112, that is, the first connector 220 is reset to the point where it is no longer in transmission connection with the lock cylinder 110. This arrangement achieves a compact structural design and ensures that the first connector 220 and the second connector 510 can be reliably reset.

[0081] The connection methods of the second elastic member 500 and the hole wall of the fourth plug hole 523 and the second connecting member 510 include but are not limited to abutment, clamping, and bonding.

[0082] Of course, in other embodiments, the second elastic member 500 may not be sleeved on the pin 230, and the two ends of the second elastic member 500 are respectively connected to the second connecting member 510 and the second connecting shaft 522. When the second connecting member 510 is disengaged from the third plug hole 112 under the push of the first connecting member 220 and is only plugged into the fourth plug hole 523, the second connecting member 510 causes the second elastic member 500 to stretch; when the key 300 is no longer subjected to external force, the second elastic member 500 retracts and resets under the action of its own elasticity, and drives the second connecting member 510 to reset to be plugged into the fourth plug hole 523 and the third plug hole 112 at the same time, and makes the first connecting member 220 no longer plugged into the third plug hole 112, even if the first connecting member 220 is reset to no longer be transmission connected to the lock cylinder 110.

[0083] Alternatively, see Figure 4The fourth insertion hole 523 is provided with a third slot 524 in its wall, and the second connector 510 is connected to a second rib 512. The second rib 512 is slidably engaged with the third slot 524, and the second rib 512 can be engaged with or separated from the second slot 113. When the second connector 510, pushed by the first connector 220, is disengaged from the third insertion hole 112 and inserted only into the fourth insertion hole 523, the second rib 512 is engaged only with the third slot 524, and the transmission connection between the second connector 510 and the lock cylinder 110 is disconnected. When the key 300 is no longer subjected to external force and the second connector 510 is reset under the elastic action of the second elastic member 500, the second connector 510 is simultaneously engaged with the fourth insertion hole 523 and the third insertion hole 112, and the second rib 512 is simultaneously engaged with the third slot 524 and the second slot 113.

[0084] The number of third slide grooves 524 and second ribs 512 can be selected as needed; in this embodiment, the second connecting member 510 is connected to two second ribs 512, and the two second ribs 512 are distributed at intervals along the circumference of the second connecting member 510; the hole wall of the fourth plug-in hole 523 is provided with two third slide grooves 524, and the two second ribs 512 are plugged into the two third slide grooves 524 in a one-to-one correspondence.

[0085] Of course, in other embodiments, the number of the third sliding groove 524 and the second rib 512 can also be one, three, etc., which is not specifically limited here.

[0086] In order to improve the stability of the key 300 sliding along the axial direction of the first plug hole 211 under the action of external force, and not easily deviate; please refer to Figure 4 and Figure 7 The first connecting shaft 210 is connected to the first sliding shaft 214 , the key 300 is provided with a first sliding groove 301 , the first sliding shaft 214 and the first sliding groove 301 are slidably plugged into each other; the length of the first sliding groove 301 extends along the axial direction of the first plug-in hole 211 .

[0087] Of course, in other embodiments, the key 300 is connected to the first sliding shaft 214, the first connecting shaft 210 is provided with a first sliding groove 301, the first sliding shaft 214 and the first sliding groove 301 are slidably plugged in; the length of the first sliding groove 301 extends along the axial direction of the first plug-in hole 211.

[0088] Alternatively, see Figure 4 and Figure 7The rotating mechanism 200 also includes a third elastic member 250 connected between the first connecting shaft 210 and the key 300. When the key 300 slides axially along the first insertion hole 211 under the action of an external force, thereby pushing the first connecting member 220 to slide relative to the first connecting shaft 210 within the second insertion hole 212, the key 300 elastically deforms the third elastic member 250. When no external force is applied to the key 300, the third elastic member 250 returns to its original position under its own elastic force, driving the key 300 to return to its original position. This arrangement improves the reliability of the key 300's return to its original position after unlocking.

[0089] Optionally, the key 300 is provided with a step portion 302, and the third elastic member 250 is sleeved on the key 300, and one end of the third elastic member 250 is abutted against the step portion 302, and the other end is abutted against the first connecting shaft 210; when the key 300 drives the first connecting member 220 to be connected to the lock cylinder 110 under the action of external force, the key 300 squeezes the third elastic member 250; when the key 300 is no longer subjected to external force, it stretches under the elastic action of the third elastic member 250 and resets the key 300 in the reverse direction.

[0090] Of course, in other embodiments, the connection method of the third elastic member 250 with the key 300 and the first connecting shaft 210 includes but is not limited to bonding, clamping, and connection with fasteners such as bolts, which is not specifically limited here.

[0091] In other embodiments, the third elastic member 250 may not be mounted on the key 300. When the key 300 drives the first connecting member 220 to be connected to the lock cylinder 110 under the action of external force, the key 300 stretches the third elastic member 250; when the key 300 is no longer subjected to external force, it retracts under the elastic action of the third elastic member 250 and resets the key 300 in the opposite direction.

[0092] In other embodiments, the rotating mechanism 200 may not include the third elastic member 250 , and the key 300 may be reset by pushing the first connecting member 220 and the pin 230 .

[0093] In order to improve the convenience of using the anti-theft lock 010, the key 300 of this embodiment is always assembled on the lock body 100; for example, please refer to Figure 8 ( Figure 8 The force applying member 310 is located at the second position) and Figure 9 ( Figure 9The force-applying member 310 is located in the first position), the key 300 includes a connecting component 320 and a force-applying member 310 rotatably connected to the connecting component 320, and the force-applying member 310 has a first position hidden in the lock body 100 and a second position extended from the lock body 100; when the force-applying member 310 is located in the second position, the force-applying member 310 can push the connecting component 320 under the action of an external force, so that the connecting component 320 drives the rotating mechanism 200 to be connected to the lock core 110 in a transmission manner, and when the rotating mechanism 200 is connected to the lock core 110 in a transmission manner, the force-applying member 310 can also drive the connecting component 320 to drive the rotating mechanism 200 to rotate.

[0094] Alternatively, see Figure 3 The front housing 101 further includes a cover plate 106. The upper cover 103 is provided with a window 107. The cover plate 106 is detachably connected to the upper cover 103 to cover or open the window 107. When the force-applying member 310 is rotated to a first position, the force-applying member 310 can be covered by the cover plate 106 connected to the upper cover 103. When the cover plate 106 is removed from the upper cover 103, the force-applying member 310 is exposed from the window 107 and can be rotated to a second position. The connection between the cover plate 106 and the upper cover 103 includes, but is not limited to, a snap connection and connection with fasteners such as bolts.

[0095] It should be understood that in other embodiments, the cover plate 106 may also be slidably connected or rotatably connected to the upper cover 103 to open or cover the window 107 by sliding or rotating.

[0096] Please refer to Figure 8 and Figure 9 When the locking cam 310 is in the unlocked position, the locking cam 310 is in the unlocked position, and the locking cam 310 is in the unlocked position, so that the locking cam 310 is unlocked. The force-applying member 310 and the connecting piece 340 are connected by the rotating member 330 , which can ensure the reliability of sliding and rotating the connecting piece 340 driven by the force-applying member 310 , thereby ensuring the reliability of unlocking.

[0097] Furthermore, the rotating member 330 is provided with a second sliding groove 331, and the force-applying member 310 is connected to a second sliding shaft 311, which is movably plugged into the second sliding groove 331. The force-applying member 310 can rotate about the rotation axis of the second sliding shaft 311 between a first position and a second position, and the second sliding shaft 311 can slide within the second sliding groove 331 to guide the force-applying member 310 to push the connecting piece 340 to move to drive the rotating mechanism 200 and transmission connection with the lock cylinder 110. The provision of the second sliding groove 331 and the second sliding shaft 311 improves the stability of the force-applying member 310 pushing the connecting piece 340 to move to drive the rotating mechanism 200 and transmission connection with the lock cylinder 110, thereby ensuring the reliability of unlocking.

[0098] Of course, in other embodiments, the force-applying member 310 is provided with a second sliding groove 331, the rotating member 330 is connected to the second sliding shaft 311, and the second sliding shaft 311 and the second sliding groove 331 are movably plugged in; the force-applying member 310 can rotate between a first position and a second position around the rotation axis of the second sliding shaft 311, and the second sliding shaft 311 can slide in the second sliding groove 331 to guide the force-applying member 310 to push the connecting piece 340 to move to the drive rotation mechanism 200 and the lock cylinder 110 for transmission connection.

[0099] Alternatively, see Figure 9 and Figure 10The opposite ends of the rotating member 330 are respectively provided with a fifth plug hole 332 and a sixth plug hole 333; the fifth plug hole 332 is connected to the sixth plug hole 333, the second sliding groove 331 is connected to the fifth plug hole 332, and the side wall of the rotating member 330 is also provided with an avoidance opening 334 connected to the fifth plug hole 332. The force member 310 can be movably arranged in the fifth plug-in hole 332. When the force member 310 is located in the first position, one end of the force member 310 is connected to the rotating member 330 through the second sliding shaft 311, and the other end of the force member 310 extends from the avoidance opening 334, and the force member 310 and the connecting piece 340 are distributed at an angle (the angle is not specifically limited, and for example, it can be 90°, 80°, 100°, etc., which is not specifically limited here); when the force member 310 is located in the second position, the end of the force member 310 away from the second sliding shaft 311 extends from the end of the fifth plug-in hole 332 away from the sixth plug-in hole 333. The connecting piece 340 can be slidably inserted into the sixth plug hole 333 and can extend into the fifth plug hole 332; since the sixth plug hole 333 is connected to the fifth plug hole 332, when the force-applying member 310 located in the second position slides along the axial direction of the fifth plug hole 332, it can push the connecting piece 340 to slide in the sixth plug hole 333 to drive the rotating component to be connected with the locking transmission, and when the force-applying member 310 rotates around its own rotation axis, it can drive the rotating member 330 to drive the connecting piece 340 to rotate synchronously, so as to utilize the connecting piece 340 to drive the rotating mechanism 200 to rotate to drive the lock cylinder 110 to retract the lock tongue 120 into the lock body 100 and unlock.

[0100] Furthermore, the end of the connecting piece 340 away from the rotating component is adapted to the sixth plug hole 333 in size and shape, so that the connecting piece 340 can slide smoothly in the sixth plug hole 333 and can reliably rotate with the rotating member 330; illustratively, the end of the connecting piece 340 away from the rotating component and the sixth plug hole 333 are both rectangular.

[0101] Furthermore, one end of the connecting piece 340 away from the rotating member 330 is movably plugged into the first plug hole 211, and the one end of the connecting piece 340 away from the rotating member 330 is adapted to the first plug hole 211 (eg Figure 6 As shown); when the force-applying member 310 is located in the second position, and the force-applying member 310 slides relative to the rotating member 330 under the action of an external force and pushes the connecting piece 340, the end of the connecting piece 340 away from the rotating member 330 can abut against the pin 230 and push the pin 230 to move; when the force-applying member 310 drives the rotating member 330 to rotate, so as to use the rotating member 330 to drive the connecting piece 340 to rotate, the connecting piece 340 can also drive the first connecting shaft 210 to rotate, and drive the first connecting member 220 to rotate through the first connecting shaft 210.

[0102] The length extension direction of the second sliding groove 331 is the same as the extension direction of the connecting piece 340 between the first plug hole 211 and the sixth plug hole 333, so as to ensure that the force applying member 310 can reliably drive the connecting piece 340 to slide in the first plug hole 211 and the sixth plug hole 333.

[0103] To improve the security of the anti-theft lock 010 during use and prevent criminals from easily unlocking the lock using the key 300 hidden in the lock body 100, the locking mechanism 400 of this embodiment is a combination lock, specifically a mechanical combination lock. Of course, in other embodiments, the combination lock can also be an electronic combination lock, which is not specifically limited here.

[0104] Please refer to Figure 11 and Figure 12 The locking mechanism 400 of this embodiment includes a combination disk assembly 420 and a locking member 450. Both the combination disk assembly 420 and the locking member 450 are movably provided on the lock body 100. Specifically, both the combination disk assembly 420 and the locking member 450 are movably provided on the bottom shell 104. The locking member 450 is configured to switch between an unlocked position and a locked position, and the combination disk assembly 420 can lock the locking member 450 in the locked position or unlock the locking member 450. When the combination disk assembly 420 unlocks the locking member 450, the locking member 450 can switch to the unlocked position and separate from the key 300. The key 300 can be brought The rotating mechanism 200 rotates. Specifically, when the locking member 450 switches to the unlocked position, it separates from the rotating member 330, and the force-applying member 310 can drive the rotating member 330 and the connecting piece 340 to rotate under the action of an external force. When the combination dial assembly 420 locks the locking member 450 in the locked position, the locking member 450 is connected to the key 300, and the key 300 cannot drive the rotating mechanism 200 to rotate. Specifically, when the locking member 450 switches to the locked position, the locking member 450 is connected to the rotating member 330, and the rotating member 330 cannot rotate. Even if the force-applying member 310 is subjected to an external force, it cannot drive the rotating member 330 and the connecting piece 340 to rotate. This arrangement can only unlock the locking member 450 and switch to the unlocked position when the user enters the correct password through the combination dial assembly 420, so that the rotating member 330 can rotate under the action of the force-applying member 310 to perform the unlocking operation, greatly improving security.

[0105] Alternatively, see Figure 10 and Figure 11The locking mechanism 400 further includes a housing 410. The combination disk assembly 420 and the locking member 450 are both movably mounted within the housing 410. The housing 410 is mounted on the bottom housing 104. That is, the combination disk assembly 420 and the locking member 450 are movably mounted on the bottom housing 104 via the housing 410. This allows the locking mechanism 400 to be assembled and then assembled as a whole in a modular manner on the bottom housing 104, ensuring ease of assembly. It should be understood that in other embodiments, the locking mechanism 400 may not include the housing 410, and the combination disk assembly 420 and the locking member 450 may be directly mounted on the base. This is not specifically limited herein.

[0106] Furthermore, the housing 410 includes a first housing 411 and a second housing 412 that are interlocked and connected. The combination disk assembly 420 and the locking member 450 are assembled between the first housing 411 and the second housing 412. The connection between the first housing 411 and the second housing 412 includes, but is not limited to, snap-fitting or fasteners such as bolts. At least one of the first housing 411 and the second housing 412 may also be connected to the rear housing 102 via snap-fitting, fasteners, or other methods.

[0107] Furthermore, the first shell 411 is provided with a first window 413 and a second window 414, and the second shell 412 is provided with an opening, and part of the password disk assembly 420 is exposed from the first window 413 to facilitate the user to unlock the password disk assembly 420; a part of the rotating member 330 is exposed from the second window 414, specifically, the opening of the fifth plug-in hole 332 and the avoidance opening 334 are both exposed from the second window 414, so that the force-applying member 310 can be exposed, ensuring the ease of operation of the user to operate the force-applying member 310 to switch between the first position and the second position.

[0108] It should be noted that the above-mentioned first window 413 and second window 414 are also exposed from the window 107 of the upper cover 103 to ensure that the password disk assembly 420 and the force-applying member 310 of the key 300 are exposed from the window 107 of the upper cover 103, so as to facilitate the user to operate the password disk assembly 420 to enter the password and apply force to the force-applying member 310.

[0109] Alternatively, see Figure 11 and Figure 12The locking member 450 has a first end and a second end that are relatively distributed. The first end of the locking member 450 is movably connected to the first housing 411 or the second housing 412, and the second end of the locking member 450 can swing around the first end. The second end of the locking member 450 can engage with or disengage from the rotating member 330. When the locking member 450 is unlocked by the combination disk assembly 420, the second end of the locking member 450 swings around the first end, separating the second end of the locking member 450 from the rotating member 330, thereby unlocking the key 300 and allowing the force-applying member 310 to drive the rotating member 330 and the connecting piece 340 to rotate under the action of an external force, thereby unlocking the door.

[0110] Furthermore, a slot 451 is provided at the second end of the locking member 450, and the rotating member 330 is connected to the engaging protrusion 335, and the slot 451 is engaged with or separated from the engaging protrusion 335; when the locking member 450 is locked in the locked position by the password disk assembly 420, the slot 451 is engaged with the engaging protrusion 335, and the rotating member 330 cannot rotate under the drive of the force-applying member 310; when the locking member 450 is unlocked by the password disk assembly 420 and switched to the unlocked position, the slot 451 is separated from the engaging protrusion 335, and the rotating member 330 can rotate under the drive of the force-applying member 310, and can drive the connecting piece 340 to rotate, so as to achieve the purpose of unlocking.

[0111] Of course, in other embodiments, the locking slot 451 is provided on the rotating member 330 , the locking protrusion 335 is connected to the locking member 450 , and the locking slot 451 is engaged with or separated from the locking protrusion 335 .

[0112] In order to ensure that the locking member 450 can be efficiently and reliably switched to the unlocked position after being unlocked by the password disk assembly 420; Figure 11 and Figure 12 The locking mechanism 400 further includes a fourth elastic member 460, which is connected to the locking member 450 and configured to switch the locking member 450 to an unlocked position. Specifically, one end of the fourth elastic member 460 is connected to the locking member 450, and the other end is connected to the second housing 412. The fourth elastic member 460 is configured to switch the locking member 450 to an unlocked position. When the locking member 450 is locked in the locked position by the combination disk assembly 420, the fourth elastic member 460 is squeezed by the locking member 450. When the locking member 450 is unlocked by the combination disk assembly 420, the fourth elastic member 460 elastically returns to its original position and extends, allowing the locking member 450 to switch to the unlocked position under the elastic action of the fourth elastic member 460.

[0113] The connection methods of the fourth elastic member 460 and the locking member 450 and the second housing 412 include, but are not limited to, abutment, clamping, and bonding.

[0114] It should be understood that in other embodiments, the two ends of the fourth elastic member 460 can also be connected to the locking member 450 and the first shell 411 respectively. When the locking member 450 is locked in the locked position by the password disk assembly 420, the fourth elastic member 460 is stretched by the locking member 450; when the locking member 450 is unlocked by the password disk assembly 420, the fourth elastic member 460 elastically resets and retracts, and the locking member 450 can be switched to the unlocked position under the elastic action of the fourth elastic member 460.

[0115] Please refer to Figure 13 The combination disk assembly 420 of this embodiment includes a combination disk 430 and an eccentric wheel 440. A plurality of markings are sequentially arranged on the circumference of the combination disk 430, for example: numerical markings 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. Of course, in other embodiments, letter markings a, b, c, d, e, f, g, etc. may also be arranged on the outer circumference of the combination disk 430; the combination disk 430 is connected to the eccentric wheel 440, and the combination disk 430 is rotatably arranged on the lock body 100. Specifically, the combination disk 430 is rotatably assembled between the first shell 411 and the second shell 412, that is, the combination disk 430 is assembled to the lock body 100 through the shell 410, and a portion of the combination disk 430 extends from the first window 413 and can be exposed from the window 107 of the upper cover 103; the eccentric wheel 440 can lock the locking member 450 in the locked position or unlock the locking member 450. With this arrangement, the combination disk 430 exposed from the window 107 of the upper cover 103 can be turned, so that the combination disk 430 drives the eccentric wheel 440 to rotate synchronously, and then the eccentric wheel 440 can be rotated to unlock or lock the locking member 450, ensuring easy unlocking and locking operations.

[0116] Optionally, the peripheral wall of the eccentric wheel 440 has an arcuate convex edge 441 and a straight edge 442 connected to the arcuate convex edge 441, and the peripheral wall of the eccentric wheel 440 abuts against the locking member 450. When the eccentric wheel 440 rotates, the peripheral wall of the eccentric wheel 440 can slide on the surface of the locking member 450; wherein, when the arcuate convex edge 441 of the eccentric wheel 440 abuts against the locking member 450, the locking member 450 switches to a locked position and is plugged into the rotating member 330; when the straight edge 442 of the eccentric wheel 440 abuts against the locking member 450, the locking member 450 can switch to an unlocked position and be separated from the rotating member 330. With such a configuration, not only can the eccentric wheel 440 be used to realize the switching of the locking member 450 between the unlocked position and the locked position, but the eccentric wheel 440 can also be used to stably support the locking member 450, ensuring that the second end of the locking member 450 can reliably swing around its first end to reliably connect or separate with the rotating member 330.

[0117] Please refer to Figure 11 、 Figure 12 and Figure 13The code disk assembly 420 further includes a first rotating shaft 421, and the eccentric wheel 440 is rotatably arranged in the housing 410 through the first rotating shaft 421; the locking member 450 is provided with a first plug interface 452, and the code disk 430 is rotatably plugged into the first plug interface 452, that is, the code disk 430 can rotate in the first plug interface 452; the eccentric wheel 440 is configured to be able to move along the axial direction of the first rotating shaft 421 synchronously with the first rotating shaft 421, and can be driven by the code disk 430. When the eccentric wheel 440 is separated from the combination disk 430, the combination disk 430 rotates independently around its own rotation axis relative to the eccentric wheel 440 to adjust the unlocking code of the combination disk 430; when the eccentric wheel 440 is in transmission connection with the combination disk 430, the combination disk 430 can drive the eccentric wheel 440 to rotate synchronously around the rotation axis of the first rotating shaft 421, so that the eccentric wheel 440 can lock the locking member 450 in the locked position or unlock the locking member 450. This arrangement allows the eccentric wheel 440 to be separated from the combination disk 430 as needed to adjust the unlocking code of the combination disk 430, and after the code adjustment is completed, the eccentric wheel 440 is restored to the transmission connection with the combination disk 430, so that the combination disk 430 drives the eccentric wheel 440 to rotate to lock or unlock the locking member 450.

[0118] Furthermore, the code disk 430 is provided with a plug-in notch 431, and the eccentric wheel 440 is connected with a convex tooth 443, which can be plugged into or separated from the plug-in notch 431. When the convex tooth 443 is plugged into the plug-in notch 431, the eccentric wheel 440 is transmission-connected with the code disk 430, that is, when the code disk 430 is turned by an external force, the eccentric wheel 440 can be driven to rotate synchronously around the axis of the first rotating shaft 421. When the convex tooth 443 is separated from the plug-in notch 431, the eccentric wheel 440 and the code disk 430 are no longer transmission-connected. The code disk 430 can be independently dialed relative to the eccentric wheel 440 to rotate independently to adjust the unlocking code of the code disk 430. After adjusting the unlocking code of the code disk 430, the convex tooth 443 is plugged into the plug-in notch 431 again, and the new code can be used to unlock the locking member 450.

[0119] It should be noted that when modifying the unlocking password of the password disk 430, it is necessary to first drive the password disk 430 to rotate the eccentric wheel 440 according to the original password until the straight edge 442 of the eccentric wheel 440 abuts against the locking piece 450, that is, first use the original password to unlock the locking piece 450, and then use the first rotating shaft 421 to drive the eccentric wheel 440 to slide along the axial direction of the first rotating shaft 421 so that the protruding tooth 443 is separated from the plug-in notch 431, and then rotate the password disk 430 alone to modify the password, and then drive the eccentric wheel 440 to slide in the opposite axial direction of the first rotating shaft 421 so that the protruding tooth 443 is plugged into the plug-in notch 431. At this time, the straight edge 442 is still abutted against the locking piece 450, that is, the password modification of the password disk 430 is completed; after the password of the password disk 430 is scrambled, it can only be unlocked using the new password.

[0120] It should also be noted that the password disk 430 is provided with a third assembly hole 432 and a plurality of plug-in notches 431. The plurality of plug-in notches 431 are all provided on the hole wall of the third assembly hole 432 and are evenly distributed around the hole wall of the third assembly hole 432; the first rotating shaft 421 is plugged into the third assembly hole 432; the position of the plug-in notch 431, the marking on the outer periphery of the password disk 430, and the position of the protruding tooth 443 provided on the eccentric wheel 440 are matched, so that after the password disk 430 is rotated to adjust the unlocking password, the protruding tooth 443 connected to the eccentric wheel 440 can still be plugged into the plug-in notch 431 corresponding to the corresponding password, thereby ensuring the reliability of the adjusted password.

[0121] Optionally, the first rotating shaft 421 is rotatably connected to the first shell 411 or the second shell 412, and the eccentric wheel 440 is fixedly connected to the first rotating shaft 421; wherein, the manner in which the eccentric wheel 440 is fixedly connected to the first rotating shaft 421 includes but is not limited to being sleeved on the first rotating shaft 421, interference fit with the first rotating shaft 421, or bonding or clamping with the first rotating shaft 421.

[0122] The number of combination disks 430 and eccentric wheels 440 can be selected as needed. In this embodiment, the combination disk assembly 420 includes four combination disks 430 and four eccentric wheels 440, which are connected or disconnected in a one-to-one manner. In this way, a four-digit combination can be used for locking, thereby improving security.

[0123] Of course, in other embodiments, the number of code disks 430 and eccentric wheels 440 can be one, two, three, five, etc., which is not specifically limited here.

[0124] It should be noted that the number of first plug-in interfaces 452 provided on the locking member 450 is adapted to the code disk 430, so that each code disk 430 can be plugged into a first plug-in interface 452, so that when the first rotating shaft 421 drives the eccentric wheel 440 to move axially along the first rotating shaft 421, the locking member 450 can reliably block the movement of the code disk 430.

[0125] Optionally, the number of first windows 413 provided on the first shell 411 is consistent with the number of code disks 430, so that each code disk 430 can be exposed from a corresponding first window 413; in this way, other structures of the locking mechanism 400 can be shielded by the first shell 411, improving the problem of the locking mechanism 400 being damaged by criminals.

[0126] Alternatively, see Figure 11 and Figure 12 The locking mechanism 400 further includes an anti-insertion piece 470 having a second insertion port 471. The anti-insertion piece 470 is connected to the side of the first housing 411 facing the second housing 412. The anti-insertion piece 470 is located on the side of the locking member 450 facing away from the fourth elastic member 460. The combination disk 430 passes through the second insertion port 471 and emerges from the first window 413. The eccentric wheel 440 is shielded by the anti-insertion piece 470 on the side facing away from the first housing 411. The provision of the anti-insertion piece 470 can alleviate the problem of criminals breaking into the eccentric wheel 440 from the outside of the lock body 100. It also alleviates the problem of criminals using a slender tool through the window 107 of the upper cover 103 and the first window 413 to press against the eccentric wheel 440, and then rotating the combination disk 430 to use the slender tool to feel whether the straight edge 442 of the eccentric wheel 440 has been rotated to abut against the locking member 450, thereby illegally unlocking the lock.

[0127] In order to modify the password of the code disk 430, please refer to Figure 13 The code disk assembly 420 of this embodiment also includes a second rotating shaft 422 and a fifth elastic member 427. The second rotating shaft 422 is rotatably arranged on the housing 410. The second rotating shaft 422 is connected to a boss 423, and the boss 423 can be transmitted and cooperated with the first rotating shaft 421; the fifth elastic member 427 is connected to the first rotating shaft 421; when the second rotating shaft 422 rotates until the boss 423 abuts against the first rotating shaft 421, the boss 423 can drive the first rotating shaft 421 to drive the eccentric wheel 440 to move to separate from the code disk 430; when the second rotating shaft 422 rotates until the boss 423 is separated from the first rotating shaft 421, the first rotating shaft 421 can drive the eccentric wheel 440 to move to be transmitted and connected with the code disk 430 under the elastic action of the fifth elastic member 427.

[0128] Furthermore, the second rotating shaft 422 is connected to two bosses 423, and the two bosses 423 are spaced apart along the axial direction of the second rotating shaft 422, and the second rotating shaft 422 is provided with a plane 425, and the plane 425 and the bosses 423 are distributed along the circumference of the second rotating shaft 422, and the plane 425 extends along the axial direction of the second rotating shaft 422; the first rotating shaft 421 is connected to an extension portion 426, and the extension portion 426 extends along the circumference of the first rotating shaft 421; when the plane 425 and the extension portion 426 are distributed relative to each other, the first rotating shaft 421 is Under the elastic action of the fifth elastic member 427, the eccentric wheel 440 is driven to move so that the protruding teeth 443 of the eccentric wheel 440 are plugged into the insertion notch 431 of the code disk 430; when the second rotating shaft 422 rotates around its own axis until one of the bosses 423 abuts against the extension 426, the boss 423 pushes the extension 426, the first rotating shaft 421 and the eccentric wheel 440 to move synchronously along the axial direction of the first rotating shaft 421, and separates the protruding teeth 443 of the eccentric wheel 440 from the insertion notch 431 of the code disk 430.

[0129] A boss 423 is provided on the second shaft 422 and an extension 426 is provided on the first shaft 421 so that when the second shaft 422 rotates, the boss 423 can reliably push the extension 426 to drive the first shaft 421 to move, thereby ensuring ease of operation in adjusting a new password.

[0130] Please note that, please refer to Figure 11 、 Figure 12 and Figure 13 When the password on the combination disk 430 is incorrect, the locking member 450 abuts against the arc-shaped convex edge 441 of the eccentric wheel 440, and the locking member 450 is in the locked position. The locking member 450 abuts against the plane 425 of the second rotating shaft 422 or is distributed with the gap 424, and the locking member 450 is distributed opposite to at least one of the two bosses 423. At this time, if the second rotating shaft 422 has a tendency to rotate around its own rotation axis, the locking member 450 will abut against the junction of at least one boss 423 and the plane 425, or the locking member 450 will abut against The lock member 450 is held on the plane 425 so that the second rotating shaft 422 cannot rotate around its own rotating axis. Therefore, when the password on the combination disk 430 is incorrect, the password cannot be changed. Only when the password on the combination disk 430 is correct, the locking member 450 switches to the unlocked position, and the gap 424 between the locking member 450 and the two bosses 423 is relatively distributed. Rotating the second rotating shaft 422 can rotate the locking member 450 to between the gap 424 between the two bosses 423, and cause the boss 423 to push the first rotating shaft 421 to realize the modification of the password.

[0131] Further, please refer to Figure 10The first shell 411 is also provided with a through hole 415, one end of the second rotating shaft 422 is rotatably inserted into the through hole 415 and exposed from the window 107 of the upper cover 103; the other end of the second rotating shaft 422 is rotatably connected to the second shell 412; such a setting can ensure the stability of the second rotating shaft 422.

[0132] Alternatively, see Figure 13 The second rotating shaft 422 is rotatably provided at one axial end of the first rotating shaft 421, and the fifth elastic member 427 is sleeved on the other axial end of the first rotating shaft 421, and one end of the fifth elastic member 427 is connected to the eccentric wheel 440 which is farthest away from the second rotating shaft 422 in the axial direction of the first rotating shaft 421, and the other end of the fifth elastic member 427 is connected to at least one of the first shell 411 and the second shell 412; when the second rotating shaft 422 drives the first rotating shaft 421 to drive the eccentric wheel 440 to separate from the code disk 430, the fifth elastic member 427 is squeezed; when the plane 425 of the second rotating shaft 422 is opposite to the extension portion 426 connected to the first rotating shaft 421, the fifth elastic member 427 extends and resets under its own elastic action, and drives the eccentric wheel 440 to drive the first rotating shaft 421 to move in the opposite direction to reset so that the eccentric wheel 440 is transmission-connected to the code disk 430.

[0133] The connection method between the fifth elastic member 427 and the corresponding eccentric wheel 440 and at least one of the first shell 411 and the second shell 412 includes but is not limited to abutment, clamping, and bonding.

[0134] It should be understood that in other embodiments, the fifth elastic member 427 can also be arranged at the same end of the first rotating shaft 421 as the second rotating shaft 422; when the second rotating shaft 422 drives the first rotating shaft 421 to drive the eccentric wheel 440 to separate from the code disk 430, the fifth elastic member 427 is stretched; when the plane 425 of the second rotating shaft 422 is opposite to the extension 426 connected to the first rotating shaft 421, the fifth elastic member 427 retracts and resets under its own elastic action, and drives the eccentric wheel 440 to drive the first rotating shaft 421 to move in the opposite direction to reset it to make the eccentric wheel 440 and the code disk 430 transmission connected.

[0135] Alternatively, see Figure 10 The end of the second shaft 422 exposed from the window 107 of the upper cover 103 is also provided with a slot 428, for example, a straight slot; so that the user can use a screwdriver and the slot 428, and then rotate the second shaft 422, ensuring the ease of operation of changing the password.

[0136] Please refer to Figure 13The rotation axis of the second rotating shaft 422 is arranged at an angle to the rotation axis of the first rotating shaft 421. In this embodiment, the angle between the rotation axis of the second rotating shaft 422 and the rotation axis of the first rotating shaft 421 is 90°. In other embodiments, the angle between the rotation axis of the second rotating shaft 422 and the rotation axis of the first rotating shaft 421 can also be 88°, 93°, etc., which is not specifically limited here.

[0137] Alternatively, see Figure 11 and Figure 12 The locking mechanism 400 also includes a spring piece 480, which is connected to the second shell 412, and the connection methods of the spring piece 480 and the second shell 412 include but are not limited to plugging, snapping, and bonding; there is a groove between two adjacent marks set on the outer periphery of the password disk 430, and the protrusion at the end of the spring piece 480 can be plugged into or separated from the groove, so as to increase the hand feel when the password disk 430 is rotated.

[0138] Furthermore, the number of the springs 480 matches the number of the code disks 430 , so as to ensure that each code disk 430 has a certain hand feel when being rotated, thereby improving the user experience.

[0139] It should be noted that other structures not mentioned in the locking mechanism 400 are similar to those in the related art and will not be described in detail here.

[0140] It should also be noted that the first elastic member 240, the second elastic member 500, the third elastic member 250, the fourth elastic member 460 and the fifth elastic member 427 are all springs; of course, in other embodiments, the first elastic member 240, the second elastic member 500, the third elastic member 250, the fourth elastic member 460 and the fifth elastic member 427 can also be torsion springs, etc., which are not specifically limited here.

[0141] When the anti-theft lock 010 of this embodiment is in use, each code disk 430 can be rotated first to input the correct code, and each eccentric wheel 440 can be rotated until the straight edge 442 is opposite to the locking member 450. The locking member 450 is swung to separate from the rotating member 330 under the action of the fourth elastic member 460, and the force-applying member 310 is rotated to the second position, pushing the force-applying member 310 toward the inside of the lock body 100 and rotating the force-applying member 310 around its own rotation axis. The force-applying member 310 can be used to drive the connecting piece 340 to push the first connecting member 220 to be plugged into the lock cylinder 110 and the first connecting shaft 210 at the same time, and under the rotation action of the force-applying member 310, the rotating member 330, the connecting piece 340, the first connecting member 220 and the unlocking dial 111 of the lock cylinder 110 are rotated, and the unlocking dial 111 can be used to drive the lock tongue 120 to retract the lock body 100 to achieve unlocking.

[0142] The process of changing the combination of the locking mechanism 400 in the anti-theft lock 010 includes: first rotating each combination dial 430 to enter the correct combination, then rotating the second shaft 422 so that one of the bosses 423 abuts against the extension 426 connected to the first shaft 421, thereby driving the first shaft 421 to cause the eccentric wheel 440 to move in the forward direction along the axis of the first shaft 421 and separate the eccentric wheel 440 from the combination dial 430; rotating the combination dial 430 to adjust the combination, and then rotating the second shaft 422 again so that the flat surface 425 of the second shaft 422 is aligned with the extension 426. The first shaft 421 and eccentric wheel 440 move in the reverse direction along the axis of the first shaft 421 under the action of the fifth elastic member 427, restoring the transmission connection between the eccentric wheel 440 and the combination dial 430. After changing the combination, the combination dial 430 can be rotated to scramble the combination.

[0143] In summary, the anti-theft lock 010 of the present invention can improve the security of unlocking with a mechanical key and improve the problem that criminals can easily unlock the lock with a mechanical key.

[0144] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
