Description

Technical Field

[0001] The invention belongs to the technical field of intelligent locks and relates to an intelligent optical delivery box lock. Background Art

[0002] An optical cross-connection box, also known as a cable junction box or street cabinet, is typically placed on a trunk optical cable. After passing through the box, large-pair optical cables are divided into smaller-pair cables in different directions. The box facilitates patching of optical cables and can also be used for testing and maintenance. An optical cross-connection box lock is a lock used to secure the box.

[0003] To prevent key loss, smart padlocks are often used as optical cross-box locks. For example, a smart padlock disclosed in a Chinese patent [authorization announcement number CN215485349U] includes a lock body, a lock shell, and a lock beam movably arranged above the lock body. The upper portion of the lock body is provided with lock holes 1 and 2, one end of the lock beam is inserted into lock hole 1, and a spring 1 is provided at the end of the lock beam. The interior of the lock body is provided with a main circuit board, a motor, and a paddle. The output shaft of the motor is provided with a cam, and the bottom of the paddle is provided with a notch that movably cooperates with the cam. One end of the lock beam is provided with a lock beam groove, and the interior of the lock body is provided with a self-locking component. The bottom of the lock body is provided with a bottom shell, an auxiliary circuit board is provided on the bottom shell, a rotatable and removable battery plug is provided at the bottom of the bottom shell, a battery is provided at the upper end of the battery plug, and an anti-dismantling component is provided within the lock body.

[0004] When the padlock is locked, the paddle is inserted into a slot at one end of the shackle beam under the action of spring 2. To unlock, the motor rotates a cam, which in turn drives a lever, which allows the paddle to exit the slot. If the padlock is dropped from a height and touches the ground, the paddle's inertia will continue to compress spring 2, causing the end of the paddle away from spring 2 to escape from the slot. Once the paddle is free, the shackle beam will separate from the lock body, rendering the padlock useless. Summary of the Invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to provide an intelligent optical cross-box lock in which the lock beam will not separate from the lock body when it falls.

[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0034] Example 1

[0035] like Figure 1 The smart optical cross-box lock shown includes a lock body 1 and a U-shaped lock beam 2. The lock body 1 is equipped with an NFC module, a controller and a battery. When unlocking, an NFC device (such as a mobile phone) is close to the lock body 1 and senses the NFC module. The NFC module transmits a signal to the controller, and the controller controls the unlocking structure in the lock body 1 (mainly controlling the motor 12) to realize the unlocking action, thereby achieving the purpose of smart unlocking.

[0036] A first lock hole 3 and a second lock hole are provided on the lock body 1. A first spring 4 is provided in the first lock hole 3. The first end 5 of the lock beam 2 is inserted into the first lock hole 3 and rests on the first spring 4. When the lock is in a locked state, the second end of the lock beam 2 is inserted into the second lock hole.

[0037] In order to achieve sealing, Figure 1 and Figure 10 As shown, a sealing ring is provided between the first lock hole 3 and the lock beam 2. In order to better fix the sealing ring, as shown in FIG. Figure 10 As shown, a first annular step is provided on the lock beam 2, and a second annular step is provided in the first lock hole 3. During assembly, the sealing ring is clamped between the first annular step and the second annular step.

[0038] In order to achieve better sealing effect, such as Figure 11As shown, the sealing ring includes a main body 34, a first sealing ring portion 35 extending upward and inward and provided on the main body 34, and a second sealing ring portion 36 extending upward and outward, that is, the cross-sectional diagram of the sealing ring is "Y"-shaped, the first sealing ring portion 35 rests on the first annular step, and the main body 34 rests on the second limiting step.

[0039] In order to achieve locking, Figure 1 As shown, a lock beam groove 6 is provided on the inner side of the first end 5 of the lock beam 2, and a slide groove 8 is provided in the lock body 1 opposite to the lock beam groove 6. A long strip-shaped locking member 7 is slidably provided in the slide groove 8. The locking member 7 has a locked state and an unlocked state. The end of the locking member 7 away from the lock beam groove 6 is provided with a second spring 9 acting on the locking member 7. Under the action of the elastic force of the second spring 9, the end of the locking member 7 close to the lock beam groove 6 is inserted into the lock beam groove 6 to put the lock beam 2 in a locked state.

[0040] In order to achieve unlocking, an unlocking structure for driving the locking member 7 from the locked state to the unlocked state is provided in the lock body 1. Figure 1 As shown, the unlocking structure includes a motor 12 provided in the lock body 1 and a cam 13 driven by the motor 12. The motor 12 is controlled by a controller. The rotating shaft of the motor 12 is parallel to the first end 5 of the lock beam 2. A cam groove 14 is provided on the locking member 7. The cam 13 extends into the cam groove 14. When the cam 13 rotates, it can drive the locking member 7 to slide in the slide groove 8. When the cam 13 rotates to a certain position, the end of the locking member 7 close to the lock beam groove 6 can completely disengage from the lock beam groove 6.

[0041] In order to prevent the lock beam 2 from detaching from the lock body 1 when falling, a stop block 10 is provided in the lock body 1 for preventing the locking member 7 from exiting the lock beam groove 6 when the unlocking structure is not actively unlocked. The lock body 1 is also provided with a driving structure for driving the stop block 10 to detach from the locking member 7 when the unlocking structure is actively unlocked. The driving structure is driven by a motor 12.

[0042] like Figure 2 As shown, the stop block 10 is rotatably installed in the slide groove 8 by a rotating shaft, and the rotating shaft is arranged perpendicular to the plane where the lock beam 2 is located. The stop block 10 has a stop surface 11 which is arranged opposite to the end of the locking member 7 away from the lock beam groove 6. When the stop block 10 is in the stop state, the distance from the stop surface 11 to the first end 5 of the lock beam 2 is less than the length of the locking member 7, that is, when it is in the unlocked state and one end of the locking member 7 rests on the stop surface 11, the other end of the locking member 7 is still inserted in the lock beam groove 6, and the driving structure can drive the stop block 10 to rotate so that the stop surface 11 is released from the limit of the locking member 7.

[0043] like Figure 2As shown, the drive structure includes a drive wheel 15 coaxially mounted on the rotating shaft of the motor 12. The drive wheel 15 has a first highest surface 16 and a first lowest surface 17 that press downward on the free end of the stop block 10. The first highest surface 16 and the first lowest surface 17 smoothly transition through a first connecting surface 18. When the first highest surface 16 presses on the free end of the stop block 10, the stop block 10 is in a stopped state. At this time, the cam 13 does not act on the locking member 7. The locking member 7 is inserted into the lock beam groove 6 under the action of the second spring 9. When the first lowest surface 17 presses on the free end of the stop block 10, the stop block 10 is released from the stopped state. At this time, the cam 13 acts on the locking member 7, causing the entire stop block 10 to rotate below the locking member 7 and causing the end of the locking member 7 inserted into the lock beam groove 6 to disengage from the lock beam groove 6.

[0044] like Figure 2 As shown, a third spring 19 is provided in the slide groove 8, the upper end of which acts on the free end of the stop block 10, and the lower end of the third spring 19 acts on the bottom of the slide groove 8. The third spring 19 makes the free end of the stop block 10 always rest against the first highest surface 16 / first lowest surface 17 / first connecting surface 18.

[0045] There are two first lowest surfaces 17 and two first connecting surfaces 18, which are symmetrically arranged along the center line of the first highest surface 16. The driving wheel 15 can rotate the retaining block 10 around the center line of the rotating shaft in both forward and reverse directions.

[0046] When the locking member 7 is in the locked state, the stop block 10 swings upward under the action of the third spring 19. At this time, the thrust surface is located at the end of the locking member 7 away from the lock beam groove 6, and there is a certain distance between the two. The size of this distance is less than the length of the locking member 7 extending into the lock beam groove 6.

[0047] When unlocking, the motor 12 drives the driving wheel 15 to rotate, and under the action of the first connecting surface 18 and the first lowest surface 17, the stop block 10 is pressed down, and the third spring 19 is compressed, so that the stop surface 11 is completely rotated from the end of the locking member 7 away from the lock beam groove 6 to the bottom of the locking member 7. At the same time, the cam 13 drives the locking member 7 to move toward the end away from the lock beam groove 6, and the second spring 9 is compressed, which eventually causes the locking member 7 to disengage from the lock beam groove 6.

[0048] Example 2

[0049] The structural principle of this embodiment is basically the same as that of the first embodiment, except that Figure 3 and Figure 4 As shown, a slide groove 8 is provided in the lock body 1 and is arranged opposite to the lock beam groove 6. The locking piece 7 is in the shape of a long strip and is slidably arranged in the slide groove 8. The end of the locking piece 7 away from the lock beam groove 6 is provided with a second spring 9 acting on the locking piece 7. Under the action of the elastic force of the second spring 9, the end of the locking piece 7 close to the lock beam groove 6 is inserted into the lock beam groove 6 to put the lock beam 2 in a locked state.

[0050] like Figure 4 As shown, a clearance cavity 20 is provided at one end of the locking member 7 close to the lock beam groove 6, and a blocking step 22 is provided on the upper part of the clearance cavity 20. An anti-slip block 21 is hinged in the clearance cavity 20, and the anti-slip block 21 can swing around the hinge center line, and its hinge center line is perpendicular to the plane where the lock beam 2 is located.

[0051] A first torsion spring (not shown in the figure) is provided between the anti-slip block 21 and the locking member 7 for making the anti-slip block 21 always swing upward (counterclockwise in the figure). The anti-slip block 21 is provided with a first limiting surface 23 which abuts against the blocking step 22 under the action of the first torsion spring. When the unlocking structure is not actively unlocked, the free end of the anti-slip block 21 extends into the lock beam groove 6.

[0052] Specifically, the yield cavity 20 is set at the lower right part of the locking member 7. When the first limiting surface 23 abuts against the blocking step 22, the lower end of the anti-slip block 21 exceeds the right end of the locking member 7. When the locking member 7 is not unlocked and is completely out of the lock beam groove 6, the lower end of the anti-slip block 21 abuts against the lower side surface of the lock beam groove 6 to prevent the lock beam 2 from falling out of the lock body 1.

[0053] like Figure 3 As shown, the unlocking structure includes a motor 12 provided in the lock body 1 and a cam 13 driven by the motor 12. The rotating shaft of the motor 12 is parallel to the first end 5 of the lock beam 2. A cam groove 14 is provided on the locking member 7. The maximum width of the cam groove 14 is equal to or slightly larger than the maximum length of the cam 13. The upper part of the cam 13 extends into the cam groove 14. When the cam 13 rotates, it can drive the locking member 7 to slide in the slide groove 8.

[0054] In the normal locking state, the end of the locking member 7 close to the lock beam groove 6 extends into the lock beam groove 6. When the unlocking mechanism is not actively unlocked and the end of the locking member 7 close to the lock beam groove 6 is separated from the lock beam groove 6, the free end of the anti-slip block 21 extends into the lock beam groove 6 under the action of the first torsion spring and abuts against the lower side of the lock beam groove 6, thereby preventing the lock beam 2 from slipping out.

[0055] When unlocking, the motor 12 drives the cam 13 to rotate, and the cam 13 causes the locking member 7 to move toward the end away from the lock beam groove 6, so that the locking member 7 and the anti-slip block 21 are completely separated from the lock beam groove 6.

[0056] Example 3

[0057] The structural principle of this embodiment is basically the same as that of the first embodiment, except that a receiving cavity 24 is provided in the lock body 1 and is arranged opposite to the lock beam groove 6. Figure 6 and Figure 7 As shown, the locking member 7 is cylindrical and is rotatably mounted in the accommodating cavity 24 via a coaxially arranged rotating shaft. The rotation centerline of the locking member 7 is perpendicular to the plane where the lock beam 2 is located. Figure 7As shown, the side of the locking member 7 is provided with a first slot 25 that cooperates with the first end 5 of the lock beam 2. When the first slot 25 is rotated to be opposite to the first end 5 of the lock beam 2, the first end 5 of the lock beam 2 can slide up and down along the first slot 25. A second torsion spring (not shown in the figure) is provided between the locking member 7 and the lock body 1. Under the action of the second torsion spring, the outer surface of the locking member 7 at the lower end of the first slot 25 can be abutted against the lower side surface of the lock beam slot 6.

[0058] like Figure 5 As shown, the unlocking structure includes a motor 12 disposed in the lock body 1 and a rotating body 26 driven by the motor 12. The rotating shaft of the motor 12 is parallel to the first end 5 of the lock beam 2. Figure 6 and Figure 7 As shown, the locking member 7 is provided with a second slot 27 extending laterally, and the rotating body 26 has a pressing portion protruding outward, the pressing portion has a second highest surface 28 and a second lowest surface 29 that press upward on the upper side of the second slot 27, the second highest surface 28 and the second lowest surface 29 are smoothly transitioned through the second connecting surface 30, when the second highest surface 28 presses on the upper side of the second slot 27, the first end 5 of the lock beam 2 can slide up and down along the first slot 25.

[0059] There are two second lowest surfaces 29 and two second connecting surfaces 30 , which are symmetrically arranged along the center line of the second highest surface 28 . The rotating body 26 can realize the rotation of the locking member 7 by both forward and reverse rotation.

[0060] When the motor 12 is in operation, it drives the rotating body 26 to rotate. This, in turn, causes the locking member 7 to rotate about the rotational centerline via the second torsion spring, the second highest surface 28, the second lowest surface 29, the second connecting surface 30, and the upper side of the second slot 27, thereby achieving locking and unlocking. Because the rotating body 26 does not move laterally, the lock beam 2 cannot fall off due to a fall.

[0061] Example 4

[0062] The structural principle of this embodiment is basically the same as that of the first embodiment, except that Figure 8 As shown, the lock body 1 is provided with an accommodating cavity 24 arranged opposite to the lock beam groove 6, and the accommodating cavity 24 has a rotatable cylinder 31. The locking member 7 is spherical and is located between the cylinder 31 and the lock beam groove 6. The side of the cylinder 31 is provided with a third slot 32 extending along its axial direction. The cross-section of the third slot 32 is arc-shaped and its inner surface is transitionally connected to the outer surface of the cylinder 31 through an arc surface 33. When the locking member 7 is located between the outer surface of the cylinder 31 and the lock beam groove 6, the lock beam 2 is in a locked state. When the locking member 7 is located between the third slot 32 and the lock beam groove 6, the lock beam 2 is in an unlocked state.

[0063] like Figure 8 and Figure 9As shown, the unlocking mechanism includes a motor 12 disposed within the lock body 1. A rotating body 37 is coaxially fixed to the rotating shaft of the motor 12. A cylindrical body 31 is coaxially arranged with the rotating body 37 and can rotate relative to the rotating body 37. A third torsion spring (not shown) is provided between the cylindrical body 31 and the rotating body 37. Under the action of the third torsion spring, the outer surface of the cylindrical body 31 is always oriented toward the lock beam slot 6. To achieve unlocking, a first connecting post 38 is fixed to the lower end of the cylindrical body 31, and a second connecting post 39 is fixed to the upper end of the rotating body 37. After the motor 12 drives the rotating body 37 to rotate to a certain angle, the second connecting post 39 abuts against the first connecting post 38. Subsequently, the first connecting post 38 drives the cylindrical body 31 to rotate in a direction that overcomes the torsion force of the third torsion spring until the third slot 32 faces the lock beam slot 6. Under the elastic force of the first spring 4, the lock beam 2 moves upward, pushing the spherical locking member 7 toward the third slot 32, achieving unlocking.

[0064] In some other embodiments, the third torsion spring is not provided, and the cylinder 31 is directly fixedly connected coaxially with the shaft of the motor 12 , and the unlocking and locking of the cylinder 31 are both controlled by the motor 12 .

[0065] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.

Under the action of the elastic force of the second spring (9), the end of the locking member (7) close to the locking beam groove (6) is inserted into the locking beam groove (6) so that the locking beam (2) is in the locked state. When the unlocking structure is provided in the lock body (1), the locking member (7) is locked. A stop block (10) is provided for preventing the locking member (7) from exiting the lock beam groove (6) when the locking member (7) is not actively unlocked. The lock body (1) is further provided with a driving structure for driving the stop block (10) to disengage from the position limiting function of the locking member (7) when the unlocking structure is actively unlocked. The stop block (10) is rotatably mounted in the slide groove (8) via a rotating shaft, and the rotating shaft is arranged perpendicular to the plane where the lock beam (2) is located. The stop block (10) has a stop surface (11) arranged opposite to an end of the locking member (7) away from the lock beam groove (6). When the stop block (10) is in the stop state, the distance from the stop surface (11) to the first end (5) of the lock beam (2) is less than the length of the locking member (7). The driving structure can drive the stop block. (10) rotates to make the stop surface (11) disengage from the limit of the locking member (7); the unlocking structure includes a motor (12) arranged in the lock body (1) and a cam (13) driven by the motor (12), the rotating shaft of the motor (12) is parallel to the first end (5) of the lock beam (2), the locking member (7) is provided with a cam groove (14), the cam (13) extends into the cam groove (14), and when the cam (13) rotates, it can drive the locking member (7) to slide in the slide groove (8), and the above-mentioned driving structure is driven by the motor (12); the driving structure includes a driving wheel (15) coaxially arranged on the rotating shaft of the motor (12), and the driving wheel (15) has a cam that presses downward on the stop block (1 0) a first highest surface (16) and a first lowest surface (17) at the free end, the first highest surface (16) and the first lowest surface (17) smoothly transition through a first connecting surface (18), when the first highest surface (16) presses on the free end of the stop block (10), the stop block (10) is in a stop state, and when the first lowest surface (17) presses on the free end of the stop block (10), the stop block (10) is out of the stop state, and a third spring (19) is provided in the slide groove (8) and acts on the free end of the stop block (10), and the third spring (19) makes the free end of the stop block (10) abut against the first highest surface (16) / first lowest surface (17) / first connecting surface (18);A sealing ring is provided between the first lock hole (3) and the lock beam (2), the sealing ring comprising a body (34), a first sealing ring portion (35) extending upward and inward and provided on the body (34), and a second sealing ring portion (36) extending upward and outward; the lock beam (2) has a first annular step, the first sealing ring portion (35) abuts against the first annular step, the first lock hole (3) is provided with a second annular step, and the body (34) abuts against the second limiting step.
