[0040] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.
[0041] like Figures 1 to 13As shown in the figure, this application embodiment provides a padlock, including a lock shell 1, a lock body 2, and a lock bar assembly 3 that cooperates with the lock body 2. The lock shell 1 has a receiving cavity 11, and the lock body 2 is located in the receiving cavity 11. The padlock also includes a lock cylinder 4, a first sensor 5, an electronic component 6, a fixing component 7, and an alarm component 8. The lock cylinder 4 is installed on the lock body 2, and the first sensor 5 is disposed on the lock cylinder 4. The lock cylinder 4 has a first keyhole 40 for inserting a key to unlock or lock. The electronic component 6 is installed in the receiving cavity 11 and is located on one side of the lock cylinder 4. The electronic component 6 has a second sensor, one of which is a transmitter and the other is a receiver. The fixing component 7 includes a fixing member 71 and an elastic member 72. The electronic component 6 has a first fixing hole 61, and both the fixing member 71 and the elastic member 72 are placed in the first fixing hole 61. One end of the elastic member 72 abuts against the bottom of the first fixing hole 61, and the other end of the elastic member 72 abuts against one end of the fixing member 71. The lock housing 1 is provided with a second fixing hole 12, and the other end of the fixing member 71 protrudes out of the electronic component 6 and is placed in the second fixing hole 12. The alarm component 8 is installed on the electronic component 6 and is electrically connected to the first sensor 5 or the second sensor.
[0042] This embodiment of the padlock includes a lock case 1, a lock body 21, a lock bar assembly 3, a lock cylinder 4, a first sensor 5, an electronic component 6, a fixing component 7, and an alarm component 8. The first sensor 5 is mounted on the lock cylinder 4, and the electronic component 6 has a second sensor. Since one of the first sensor 5 and the second sensor is a transmitter and the other a receiver, and the alarm component 8 is electrically connected to either the first sensor 5 or the second sensor, the distance between the first sensor 5 and the second sensor changes as the lock cylinder 4 is rotated by the key. Alarm conditions are set based on the change in distance between the first sensor 5 and the second sensor. Through the design of the first sensor 5, the second sensor, and the alarm component 8, the user is promptly alerted when the padlock is damaged, and criminals are deterred, thus improving its anti-theft performance.
[0043] In one embodiment, the first sensor 5 may be a receiver and the second sensor may be a transmitter; or the first sensor 5 may be a transmitter and the second sensor may be a receiver.
[0044] Preferably, in this embodiment, the first sensor 5 is a receiver, and the second sensor is a transmitter. When the first sensor 5 is a transmitter, it can be a magnetic field emitting device, specifically, a magnet used to generate a magnetic field. The second sensor is a magnetic field receiving device, used to sense the magnetic field generated by the magnet and generate a corresponding electromagnetic signal.
[0045] Since the magnet is mounted on the lock cylinder 4, it rotates with the lock cylinder 4, changing its position and consequently altering the position between the magnet and the magnetic field receiver. When the padlock is unlocked, the distance between the magnet and the magnetic field receiver is greatest, resulting in the weakest signal received by the receiver. When the padlock is locked, the distance is smallest, and the signal received is strongest. This embodiment can set an alarm based on the change in signal strength received by the magnetic field receiver. The alarm component 8 determines whether to alarm based on changes in the electromagnetic signal. The alarm component 8 includes a speaker 81 and a vibration sensor. The speaker 81 is located at one end of the lock housing 1 and broadcasts alarm messages.
[0046] In one embodiment, the electronic component 8 may also be provided with a circuit board, which is electrically connected to the second sensor and alarm component 8.
[0047] In one embodiment, to accommodate the installation of the first sensor 5, the lock cylinder 4 includes a lock core 41, a lock cylinder shell 42, and a lock plate 43. The lock core 41 is installed inside the lock cylinder shell 42, and the lock plate 43 is installed on the lock core 41. The lock core 41 and the lock plate 43 can rotate axially within the lock cylinder shell 42. A rotating pin 44 that cooperates with the lock plate 43 is also installed on the lock core 41. The lock core 41 is made of high-strength alloy steel and has a cylindrical blind hole 45 on its side. The first sensor 5 is installed inside the blind hole 45. A first lock hole 40 is located on the lock plate 43.
[0048] To facilitate the installation of the lock cylinder 4 on the lock body 2, the lock body 2 includes a lock body 21. The lock body 21 has a lock cylinder mounting groove 211 that extends vertically through it, and the lock cylinder 4 is installed within the lock cylinder mounting groove 211. To secure the lock cylinder 4 within the lock cylinder mounting groove 211, a fixing protrusion 46 is provided on the outer circumferential surface of the lock cylinder shell 42 along its length. A fixing groove 212 is provided on the inner wall of the lock cylinder mounting groove 211, and the fixing protrusion 46 is placed within the fixing groove 212. The locking protrusion 46 and the fixing groove 212 secure the lock cylinder shell 42, preventing it from rotating when the lock cylinder 41 and lock plate 43 rotate.
[0049] In one embodiment, to limit the movement of the lock cylinder 41, a first limiting post 47 and a second limiting post 48 are provided on the lock cylinder 41. A first limiting groove 421 is provided on the lock cylinder shell 42 along its circumference, and a second limiting groove 212 is provided on the inner wall of the lock cylinder mounting groove 211 along its circumference. The first limiting post 47 moves within the first limiting groove 421, and the second limiting post 48 moves within the second limiting groove 212. Since the first limiting post 47 is located within the first limiting groove 421 and the second limiting post 48 is located within the second limiting groove 212, the movement of the lock cylinder 41 is limited by the first limiting post 47 and the first limiting groove 421, and by the second limiting post 48 and the second limiting groove 212.
[0050] In one embodiment, the fixing component 7 further includes a fixing end cap 73, which is installed within the first fixing hole 61. Preferably, the fixing end cap 73 can be installed within the first fixing hole 61 by means of threaded connection or the like. The fixing end cap 73 has a limiting hole 731 in its middle and a first limiting part 732 on its surface. A second limiting part 74 is fitted onto the fixing member 71, and an elastic member 72 is fitted onto one end of the fixing member 71. The second limiting part 74 is located between the first limiting part 732 and the elastic member 72, and abuts against the first limiting part 732. The second limiting part 74 limits the elastic member 72, and the first limiting part 732 limits the fixing member 71, preventing the fixing member 71 from moving out of the first fixing hole 61. The lock housing 1 has a second fixing hole 12, and the other end of the fixing member 71 passes through the first fixing hole 61 and is placed within the second fixing hole 12. Preferably, the elastic member 72 is a spring.
[0051] Furthermore, to facilitate the installation of the electronic component 6, a mounting cavity 213 is provided on the lock body 21, and the electronic component 6 is installed within the mounting cavity 213. Resilient mounting grooves 214 are respectively provided on opposite side surfaces of the lock body 21, and springs 218 are respectively installed in the two elastic mounting grooves 214. One end of the spring 218 abuts against the inner wall of the elastic mounting groove 214, and the other end of the spring 218 abuts against one end of the electronic component 6. Preferably, one end of the spring 218 is connected to the inner wall of the elastic mounting groove 214.
[0052] During installation, the electronic component 6 is first moved into the first fixing hole 61 by pressing the fixing member 71. Then, the electronic component 6 is pushed into the lock housing 1 from one end. After the electronic component 6 is in place, the other end of the fixing member 71 moves into the second fixing hole 12 under the elastic force of the elastic member 72, thereby locking the electronic component 6. In the locked state, the two springs 218 are compressed. The installation of the electronic component 6 can be achieved without tools, making the installation method convenient and quick.
[0053] When it is necessary to remove the electronic component 6, use a steel needle or other tool to press down on the other end of the fixing member 71, disengaging it from the second fixing hole 12. At this time, under the elastic force of the two springs 218, the two springs 218 push the electronic component 6 from inside the lock housing 1 towards one end of the lock housing 1, thus automatically ejecting the electronic component 6 from the lock housing 1, facilitating its removal. The electronic component 6 is equipped with a battery, which powers the second sensor and alarm component 8. After the electronic component 6 is removed, it is easy to replace or recharge the battery.
[0054] In one embodiment, to enable the padlock to lock or unlock, the lock body 2 further includes a first bolt 22 and a second bolt 23. The first bolt 22 and the second bolt 23 are mounted on the lock body 21, and the lock cylinder 41 is connected to the first bolt 22 and the second bolt 23. The lock cylinder 41 drives the first bolt 22 and the second bolt 23 to move towards or away from each other on the lock body 21. The first bolt 22 and the second bolt 23 are made of high-strength alloy steel.
[0055] The lock body 21 has two first lock rod insertion holes 215, with a first lock tongue 22 and a second lock tongue 23 located between the two first lock rod insertion holes 215. The lock rod assembly 3 includes two connected lock rods 31, which form a U-shaped structure when connected. Each of the two lock rods 31 has a locking hole 311, and a locking pin 24 is respectively provided at the opposite ends of the first lock tongue 22 and the second lock tongue 23. After the two lock rods 31 are inserted into the two first lock rod insertion holes 215, the lock cylinder 41 drives the first lock tongue 22 and the second lock tongue 23 to move in opposite directions, and the two locking pins 24 are respectively inserted into the two locking holes 311 for locking. In this embodiment, the lock rods 31 are also made of high-strength alloy steel. The locking pins 24 can be cylindrical or other shapes.
[0056] To move the first bolt 22 and the second bolt 23, two drive pins 49 are provided at the top of the lock cylinder 41. Drive slots 25 are respectively provided at the ends of the first bolt 22 and the second bolt 23 that are close to each other, and the two drive pins 49 are located within the two drive slots 25. When the lock cylinder 41 rotates, the two drive pins 49 and the two drive slots 25 drive the first bolt 22 and the second bolt 23 to move towards or away from each other on the lock body 21. To limit the movement of the first bolt 22 and the second bolt 23, two movement limiting slots 216 are provided on the lock body 21, and the two drive pins 49 are respectively located within the two movement limiting slots 216, thereby limiting the movement of the first bolt 22 and the second bolt 23.
[0057] When unlocking, the key is inserted into the first keyhole 40. As the key turns, it drives the lock cylinder 41 to rotate within the lock shell 42. The rotation of the lock cylinder 41, via two drive pins 49, causes the first bolt 22 and the second bolt 23 to move in opposite directions, removing the locking pins 24 on the first bolt 22 and the second bolt 23 from the two locking holes 311, thus releasing the two locking rods 31. At this time, the two locking rods 31 can freely enter and exit the two first locking rod insertion holes 215, and the locking rod assembly 3 can be freely separated from the lock body 2. When locking, the key is inserted into the first keyhole 40. The key drives the lock cylinder 41 to rotate in the opposite direction within the lock shell 42. The lock cylinder 41, via two drive pins 49, causes the first bolt 22 and the second bolt 23 to move in opposite directions, thereby inserting the two locking pins 24 on the first bolt 22 and the second bolt 23 into the two locking holes 311 respectively to achieve locking. At this time, the locking rods 31 cannot be pulled out from the two first locking rod insertion holes 215.
[0058] In one embodiment, to lock the locking rod assembly 3 to the lock body 21, a latching flat portion 312 is provided at the bottom of the two locking rods 31, and two fixing holes 217 are provided on the lock body 21. After the bottom of the two locking rods 31 is respectively inserted into the two fixing holes 217, the latching flat portion 312 engages with the side of the fixing hole 217. The latching flat portion 312 and the locking hole 311 are located on different sides of the locking rods 31. By setting the latching flat portion 312 and the locking hole 311, the locking rod 31 cannot be opened by rotation even if it is sawn off, further improving the security of the padlock.
[0059] In one embodiment, the lock housing 1 includes a lock tube body 12, a first lock tube 13, and a second lock tube 14. A receiving cavity 11 is placed inside the lock tube body 12. The first lock tube 13 and the second lock tube 14 are respectively fitted onto both ends of the lock tube body 12 and are connected to the lock tube body 12 by bolts. A second fixing hole 12 is located on the lock tube body 12. The first lock tube 13 and the second lock tube 14 are each provided with a second lock rod insertion hole 15. The lock tube body 12 is provided with two third lock rod insertion holes 16, each corresponding to one of the two second lock rod insertion holes 15. The two third lock rod insertion holes 16 are positioned corresponding to the two first lock rod insertion holes 215. A fourth lock rod insertion hole 62 is provided on the electronic component 6, and the fourth lock rod insertion hole 62 is positioned corresponding to one of the first lock rod insertion holes 215.
[0060] In this embodiment of the application, when the padlock is unlocked, the distance between the first sensor 5 and the second sensor is the greatest, and the signal received by the second sensor is the weakest, thus deactivating the anti-theft alarm. When the padlock is locked, the distance between the first sensor 5 and the second sensor is the closest, and the signal received by the second sensor is the strongest, allowing for an alarm-on or alarm-off state. When the alarm is activated, the alarm component 8 will continuously emit an alarm sound when the padlock is subjected to external vibration or impact. In the alarm-off state, the alarm is disabled when the padlock is subjected to external vibration or impact.
[0061] The electronic component 6 and alarm component 8 of the padlock in this embodiment adopt a modular design. The alarm component 8 can be fixed to the electronic component 6 with screws or the like, which facilitates the removal, maintenance, replacement and charging of the electronic component 6. The electronic component 6 is located inside the lock housing 1, which is not easily damaged and has high security. Moreover, the electronic component 6 can be installed and removed without the aid of tools, which is convenient and quick.
[0062] It should be noted that: such as Figure 14 As shown, the lock cylinder 4 in this embodiment can be a conventional digital lock cylinder 4 or a pin tumbler lock cylinder 4, and is not specifically limited. The working principle and working method of the second sensor are all prior art, and this application does not improve upon them.
