Description

Technical Field

[0001] The present application relates to the technical field of locks, and in particular to a padlock. Background Art

[0002] In some special application scenarios, such as during substation maintenance and isolation operations, inadvertent locking of padlocks or illegal locking by unauthorized personnel will cause trouble to normal work, and in serious cases may even cause property damage and personal safety issues.

[0003] Therefore, some padlocks that need to be strictly controlled have appeared on the market. Both unlocking and locking of the padlocks need to be authorized by an appropriate computer key. Such padlocks usually include an electronic lock core and a locking component. After the computer key is authorized, the electronic lock core drives the locking component to perform unlocking and locking operations.

[0004] However, in the related art, the locking assembly of this padlock usually includes a locking part and an elastic part. When authorized to unlock, the electronic lock core drives the locking part to squeeze the elastic part, so that the locking part unlocks the lock hook. When authorized to lock, the electronic lock core drives the locking part to cancel the squeezing of the elastic part, and the elastic part releases the elastic potential energy to drive the locking part to lock the lock hook. In this way, the locking assembly is not only complex in structure, but also includes an elastic part, which makes it easy for the locking assembly to fail when it is knocked or vibrated, resulting in low reliability of the padlock. Utility Model Content

[0017] When the padlock is unlocked, the rotating shaft drives the two locking rods to move closer to each other in the transverse direction, so that the locking ends of the two locking rods are disengaged from the corresponding locking grooves, thereby unlocking the lock hook;

[0018] When the padlock is locked, the rotating shaft drives the two locking rods to move away from each other in the transverse direction, so that the locking ends of the two locking rods are respectively plugged into and matched with the corresponding locking grooves to lock the lock hook.

[0045] The present invention proposes a padlock 100, the unlocking and locking of which require authorization from a compatible computer key, thus achieving strict control. Figures 1 to 4 In an embodiment of the present invention, the padlock 100 includes a lock body 10 , an electronic lock cylinder 20 , a locking assembly 30 and a lock hook 40 .

[0046] The electronic lock core 20 is installed on the lock body 10. The electronic lock core 20 includes a lock core shell 21 and a lock core module 22. The lock core shell 21 is provided with a rotation groove 211. The lock core module 22 is rotatably installed in the rotation groove 211. The lock core module 22 is used to connect to an adapted computer key and rotate along a first direction or a second direction under the control of the computer key, wherein the first direction is opposite to the second direction.

[0047] It can be understood that when the first direction is clockwise, the second direction is counterclockwise. Similarly, when the first direction is counterclockwise, the second direction is clockwise.

[0048] The electronic lock core 20 can be installed on the lock body 10 through a spring 50 , or the electronic lock core 20 can be fixed on the lock body 10 through a stud.

[0049] There are various ways to rotatably mount the lock core module 22 in the rotating groove 211. In one example, the peripheral side of the lock core module 22 can directly rotatably abut against the inner wall of the rotating groove 211. In another example, the lock core module 22 can be rotatably mounted in the rotating groove 211 through a bearing.

[0050] The locking assembly 30 includes a locking member 31 and a rotating shaft 32 . The locking member 31 is slidably disposed in the lock body 10 . One end of the rotating shaft 32 is transmission-connected to the locking member 31 , and the other end of the rotating shaft 32 is fixedly connected to the lock core module 22 .

[0051] When unlocking, the computer key is inserted and the lock core module 22 is rotated in the first direction, so that the lock core module 22 rotates along the first direction and synchronously drives the rotating shaft 32 to rotate along the first direction to drive the locking member 31 to slide, so that the locking member 31 is released from the limit with the lock hook 40 to unlock the lock hook 40.

[0052] When locking, the computer key is inserted and the lock core module 22 is rotated in the second direction, so that the lock core module 22 rotates along the second direction, and synchronously drives the rotating shaft 32 to rotate along the second direction to drive the locking member 31 to slide, so that the locking member 31 and the lock hook 40 are limited to lock the lock hook 40.

[0053] It should be emphasized that a computer key compatible with the lock core module 22 can authorize the lock core module 22. Only after authorization can the lock core module 22 rotate under external force. When the lock core module 22 rotates to a preset position, the authorization state of the lock core module 22 is automatically released. At this time, the lock core module 22 will not rotate even if subjected to external force. The preset position refers to the position of the lock core module 22 when the locking member 31 locks the lock hook 40 and the position of the lock core module 22 when the locking member 31 unlocks the lock hook 40. The external force that drives the lock core module 22 to rotate is usually the rotation of the computer key. The computer key can establish a communication connection with the lock core module 22 via wired or wireless means to realize the authorization of unlocking and locking operations.

[0054] It can be understood that the locking member 31 is slidably arranged in the lock body 10 and can slide when the locking member 31 is subjected to force. In the embodiment of the present application, one end of the rotating shaft 32 is transmission-connected to the locking member 31, so when the locking member 31 is driven by the rotating shaft 32, it can slide.

[0055] The padlock 100 provided by the present invention, through the above-described structural arrangement, allows the padlock 100 to be unlocked by connecting the lock cylinder module 22 via a computer key. Once the lock cylinder module 22 is authorized to rotate, the computer key can be used to drive the lock cylinder module 22 to rotate in a first direction or a second direction, thereby driving the locking member 31 to slide, causing the locking member 31 to lock or unlock the hook 40, thereby achieving the dual-authorization unlocking function of the padlock 100. It can be seen that the technical solution of the present invention is simple in structure. Compared with the prior art, the present invention does not require an elastic member to release elastic potential energy when locking the hook 40. Therefore, the present invention does not require an elastic member. The lock cylinder module 22 synchronously drives the rotating shaft 32 to rotate in the first direction or the second direction, thereby driving the locking member 31 to slide, thereby locking or unlocking the hook 40. This avoids the problem of the locking assembly 30 being easily damaged when the padlock 100 is struck or vibrated, thereby improving the reliability of the padlock 100.

[0056] In some examples, such as Figures 2 to 4 As shown, the locking member 31 is slidably disposed transversely on the lock body 10. The locking member 31 is also provided with a drive slot 312 along a third direction perpendicular to the transverse direction. A boss 321 is provided on the end of the rotating shaft 32 away from the lock core module 22. The boss 321 is spaced from the axis of rotation of the rotating shaft 32 and is in driving engagement with the drive slot 312. When the padlock 100 is unlocked, the rotating shaft 32 drives the locking member 31 to slide transversely away from the hook 40, disengaging the locking member 31 from the lock slot 411 of the hook 40 to unlock the hook 40. When the padlock 100 is locked, the rotating shaft 32 drives the locking member 31 to slide transversely toward the hook 40, causing the locking member 31 to lock and engage with the lock slot 411 of the hook 40 to lock the hook 40.

[0057] With this arrangement, when the lock cylinder module 22 is rotated to synchronously rotate the shaft 32, the boss 321 abuts and engages with the wall of the drive slot 312. This abutment and engagement between the boss 321 and the wall of the drive slot 312 transmits power to the locking member 31, thereby driving the locking member 31 to slide laterally. Furthermore, the simple transmission engagement between the boss 321 and the drive slot 312 further enhances the reliability of the padlock 100 and facilitates assembly of the padlock 100.

[0058] In some examples, such as Figures 2 to 4As shown, the lock hook 40 is provided with two locking grooves 411. The locking member 31 includes two locking rods 311, which are each slidably disposed laterally within the lock body 10. One end of each locking rod 311 is provided with a locking end 313 that engages with the corresponding locking groove 411, and the other end of each locking rod 311 is provided with a driving groove 312. The end of the rotating shaft 32, away from the lock core module 22, is provided with two axially symmetrical protrusions 321 that engage with the corresponding driving grooves 312. When the padlock 100 is unlocked, the rotating shaft 32 drives the two locking rods 311 laterally toward each other, causing the locking ends 313 of the two locking rods 311 to disengage from the corresponding locking grooves 411, thereby unlocking the lock hook 40. When the padlock 100 is locked, the rotating shaft 32 drives the two locking rods 311 to move away from each other in the transverse direction, so that the locking ends 313 of the two locking rods 311 are respectively engaged with the corresponding locking grooves 411 to lock the lock hook 40.

[0059] With this arrangement, the two locking rods 311 of the locking member 31 can respectively cooperate with the corresponding locking grooves 411, thereby increasing the contact between the locking member 31 and the lock hook 40 and dispersing the force on the locking member 31 in the lateral direction, thereby further improving the reliability of the padlock 100.

[0060] In some examples, such as Figures 2 to 4 As shown, the lock hook 40 includes a first section 41, a connecting section 42, and a second section 43. The first section 41 and the second section 43 are arranged parallel to each other, and the connecting section 42 is connected to the first section 41 and the second section 43 at both ends. The first section 41 is movably connected to the lock body 10, so that the lock hook 40 can have a first state in which the second section 43 is retracted from the lock body 10, and a second state in which both the first section 41 and the second section 43 are inserted into the lock body 10. The first section 41 is sequentially provided with a locking groove 411 and an abutment portion 412 in a direction away from the connecting section 42. The abutment portion 412 is used to abut and limit the locking member 31 to restrict the rotation of the lock core module 22. The first section 41 is movably connected to the lock body 10 via a spring 44, so that the lock hook 40 is ejected when the locking member 31 unlocks the lock hook 40.

[0061] With such arrangement, when the second section 43 exits the lock body 10 and is in the second state, the locking member 31 is in abutment with the abutment portion 412 on the first section 41, so the locking member 31 cannot move, and the lock core module 22 is restricted by the locking member 31 and cannot rotate enough. In this way, the operation of rotating the lock core module 22 to accidentally lock the lock when the second section 43 has not entered the lock body 10 can be avoided, so that the actual state of the padlock 100 is consistent with the information of the computer key.

[0062] It should be emphasized that, in other examples, the lock hook 40 can be completely separated from the lock body 10 when the padlock 100 is in the unlocked state.

[0063] In some examples, such as Figures 2 to 4 As shown, a limit groove 413 is further provided at one end of the first section 41 away from the connecting section 42. The limit groove 413 extends along the length direction of the first section 41. The lock body 10 is also provided with a limit pin 11 that is movably abutted against the limit groove 413, so as to limit the movable stroke of the first section 41 along its length direction through the cooperation between the limit pin 11 and the limit groove 413.

[0064] This arrangement is intended to prevent the lock hook 40 from excessively extending from the lock body 10 or detaching from the lock body 10, and the position of the lock slot 411 can be correspondingly set by adjusting the movable stroke of the first section 41 along its length direction to improve the locking efficiency of the padlock 100.

[0065] In some examples, such as Figures 2 to 4 As shown, an annular avoidance groove 414 is provided at one end of the limiting groove 413 away from the connecting section 42 . The annular avoidance groove 414 is used to accommodate the limiting pin 11 so that the first section 41 rotates along its axis.

[0066] With such a configuration, after the first section 41 moves to its limit along its length direction, the annular avoidance groove 414 can accommodate the limit pin 11 to avoid the limit pin 11, so that the first section 41 will not be restricted when rotating along its axis, thereby improving the flexibility of the padlock 100.

[0067] In some examples, such as Figure 5 and Figure 6 As shown, the electronic lock core 20 includes a first sensor, a second sensor and a detection component. The first sensor and the second sensor are respectively fixedly mounted on the lock core shell 21; the detection component is fixedly mounted on the lock core module 22, and enables the detection component to detect the first sensor when the locking member 31 locks the lock hook 40, and detect the second sensor when the locking member 31 unlocks the lock hook 40.

[0068] Such a configuration is intended to detect the first sensing element and the second sensing element through the detection component, thereby truly recording the actual state of the padlock 100 and transmitting the information to the computer key.

[0069] In some examples, such as Figure 5 and Figure 6 As shown, the detection component includes a bipolar Hall sensor 23, the first sensing member and the second sensing member both include a magnet 24, the S magnetic pole of the magnet 24 of the first sensing member is toward the lock core module 22, and the N magnetic pole of the magnet 24 of the second sensing member is toward the lock core module 22; or, the detection component includes a bipolar Hall sensor 23, the first sensing member and the second sensing member both include a magnet 24, the N magnetic pole of the magnet 24 of the first sensing member is toward the lock core module 22, and the S magnetic pole of the magnet 24 of the second sensing member is toward the lock core module 22.

[0070] Such an arrangement is intended to further improve the accuracy of the detection component in detecting the first sensing element and the second sensing element.

[0071] In some examples, such as Figures 1 to 7 As shown, the lock core module 22 includes a connecting component 221 and a control component 222, the control component 222 includes a driver 2221 and a lock core shell 2222, the lock core shell 2222 is rotatably installed in the rotation groove 211, and the driver 2221 is fixedly installed in the lock core shell 2222; the connecting component 221 includes a connecting seat 2211 and a lock tongue 2214, one side of the connecting seat 2211 is fixedly connected to the rotating shaft 32, and the other side of the connecting seat 2211 is fixedly connected to the lock core shell 2222, the connecting seat 2211 is radially provided with a sliding hole 2212 and is connected to the rotation groove 211, the lock tongue 2214 is movably installed in the sliding hole 2212, and the lock tongue 2214 is fixedly abutted against the peripheral wall of the rotation groove 211 under the control of the driver 2221 to lock the lock core shell 21 and the lock core module 22, or, movably abutted against the peripheral wall of the rotation groove 211 to unlock the lock core shell 21 and the lock core module 22. In this example, the locking tongue 2214 can be movably installed in the sliding hole 2212 via a sleeve spring 2215 .

[0072] When the lock core module 22 is unlocked, the lock tongue 2214 is fixedly abutted against the peripheral wall of the rotation groove 211 under the control of the driver 2221, that is, the lock tongue 2214 is restricted in its movement by the driver 2221, and the lock tongue 2214 cannot move relative to the rotation groove 211, at this time, the lock core housing 21 and the lock core module 22 are locked; when the lock core module 22 is authorized, the lock tongue 2214 is movably abutted against the peripheral wall of the rotation groove 211 under the control of the driver 2221, that is, the lock tongue 2214 is not restricted in its movement by the driver 2221, and the lock tongue 2214 can move relative to the rotation groove 211 to unlock the lock core housing 21 and the lock core module 22. After the lock core module 22 is rotated to the preset position, the authorization obtained by the lock core module 22 is cancelled, and the lock core module 22 becomes the unauthorized state, that is, the lock tongue 2214 is fixedly abutted against the peripheral wall of the rotation groove 211 under the control of the driver 2221.

[0073] In some examples, such as Figure 5 and Figure 6 As shown, the groove wall of the rotating groove 211 is provided with a pit 212 corresponding to a preset position, so that the locking tongue 2214 can cooperate with the pit 212 to achieve fixed contact with the peripheral wall of the rotating groove 211.

[0074] In some examples, such as Figures 5 to 7As shown, the connecting seat 2211 is also provided with an iron core groove 2213, and the iron core groove 2213 is connected to one end of the sliding hole 2212 away from the peripheral wall of the rotating groove 211. The driver 2221 includes a solenoid driver 22211 and an iron core 22212. The solenoid driver 22211 drives the iron core 22212 to be accommodated in the iron core groove 2213 to limit the movement of the lock tongue 2214, so that the lock tongue 2214 is fixedly abutted against the peripheral wall of the rotating groove 211 to lock the lock core shell 21 and the lock core module 22.
