[0046] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0047] Example:

[0048] Please see Figures 1-12 The ring lock includes: a lock box 1 with a lock hole 101 on one side; a locking member 2, one end of which is connected to the lock box 1, and the other end of which can freely enter and exit the lock box 1 through the lock hole 101; an electronic locking assembly 3, which is disposed inside the lock box 1 and is used to lock or unlock the locking member 2 that extends into the lock box 1; a lever 4, which is disposed inside the lock box 1, one end of which extends out of the lock box 1 and slides on the lock box 1, and the other end abuts against one side of the electronic locking assembly 3 to push the electronic locking assembly 3 to unlock the locking member 2; and a rotary combination lock 5, with a knob 501 disposed outside the lock box 1 and a lock cylinder 502 disposed inside the lock box 1, the knob 501 being used to drive the lock cylinder 502 to limit or cancel the limit of the lever 4.

[0049] The ring lock provided in this utility model is used for simple locking of various items. That is, the item is bound between the lock box 1 and the locking component 2 by the locking component 2. For example, for a double door gate in a factory, the locking component 2 is passed through the door handles on the two doors, so that the door handles of the two doors are bound between the locking component 2 and the lock box 1. For example, for the tire of an electric vehicle, the locking component 2 can be passed through the wheel hub and the roadside guardrail. The tire is bound to the locking component 2 connected to the guardrail by the cooperation of the locking component 2 and the lock box 1.

[0050] like Figures 1-5 As shown, in this embodiment, the ring lock includes a lock box 1, a locking member 2, an electronic locking assembly 3, a dial block 4, and a rotary combination lock 5. One end of the locking member 2 is connected to the lock box 1. The electronic locking assembly 3 can lock or unlock the other end of the locking member 2. The rotary combination lock 5 can remove the limit on the dial block 4. After the dial block is removed from the limit, it can slide in the lock box 1, and when it slides, it drives the electronic locking assembly 3 to unlock the locking member 2.

[0051] Specifically, the lock box 1 is a box with an internal cavity, preferably made of metal. The surface of the lock box 1 has no keyhole structure, and one side of the lock box 1 has a lock hole 101 connecting the interior and exterior of the lock box 1. One end of the upper locking member 2 is connected to the lock box 1, which can be welded or snap-fitted. Preferably, in this embodiment, one end of the upper locking member 2 has a round rod (not shown), and the round rod has a groove for engaging and fixing with the side wall of the lock box 1. The lock box 1 consists of a box body (not shown) and a top cover (not shown). After separating the box body and the top cover, one end of the upper locking member 2 can be separated from the lock box 1. The other end of the upper locking member 2 can freely enter and exit the lock box 1 through the lock hole 101. The upper locking member 2 can be a long strip of metal that can be freely bent, such as a steel rope or metal chain, or a fixed U-shaped handle. The electronic locking component 3 is disposed in the lock box 1 to lock or unlock the upper locking member 2 that extends into the lock box 1.

[0052] The bottom end of the lever 4 is disposed in the lock housing 1, and one side of the bottom end abuts against one side of the electronic locking component 3. Specifically, the bottom end of the lever 4, near the unlock position, abuts against the electronic locking component 3 to push the electronic locking component 3 to move to the unlock position and unlock the upper locking member 2. The top end of the lever 4 extends out of the lock housing 1 and is slidably disposed on the lock housing 1. One side of the lock housing 1 is provided with an elongated sliding hole, and the top end of the lever 4 passes through the elongated sliding hole, allowing the user to slide the lever 4 with their finger outside the lock housing 1.

[0053] The rotary combination lock 5 is a rotary combination lock 5 or a knob 501 combination lock commonly used in existing combination lock boxes. The knob 501 of the rotary combination lock 5 is located on the outside of the lock box 1. The lock cylinder 502 of the rotary combination lock 5 has multiple grooved rotary discs (not shown) and a rotating shaft (not shown) for driving each rotary disc to rotate. The knob 501 is fixedly connected to the rotating shaft, and the rotating shaft engages with the bottommost rotary disc to drive the bottommost rotary disc to rotate. Each rotary disc has a protrusion (not shown) on its opposite side. As shown in the diagram, the rotation of the bottom turntable, caused by the cooperation of various protrusions, drives the rotation of the other turntables. When the knob 501 is rotated to align the multiple grooves on each turntable with the lever 4, the turntable combination lock 5 releases the lever 4 from its limiting position. The lever 4 has room to move (sliding within the grooves). Moving the top of the lever 4 moves the slider 3011. When the multiple grooves on each turntable are not aligned, the sides of some or all of the turntables abut against the lever 4, thus limiting its position. Furthermore, a baffle 403 is provided on one side of the lever 4. The lever 4 is limited or released from its limiting position by cooperating with the lock cylinder 502 of the turntable combination lock 5 through the baffle 403.

[0054] When in use, the rotary combination lock 5 aligns the grooves on the multiple dials by rotating the clockwise and counterclockwise knobs 501. At this point, the dials no longer press against the stop plate 403, thus unlocking the lever 4. The lever 4 can then be manually moved to slide the slider 3011 to the unlock position to complete the unlocking. When the electronic locking assembly 3 is de-energized, and the user cannot unlock the upper locking member 2 using the electronic locking assembly 3, the rotary combination lock 5 can be used to release the lever 4 from its limit position. Then, the lever 4 drives the electronic locking assembly 3 to unlock the upper locking member 2. After unlocking, the lever 4 is manually reset, and rotating the knob 501 again de-aligns the grooves on the dials, thus re-limiting the lever 4. When the rotary combination lock 5 limits the movement of the dial block 4, the dial block 4 cannot be moved. The end of the electronic locking component 3 used to lock the upper locking member 2 is movable within the lock housing 1. When the movable end of the electronic locking component 3 actively unlocks the upper locking member 2, that end slides relative to the dial block 4. At this time, the point where the electronic locking component 3 and the dial block 4 are in contact will separate. They will only re-engage with the dial block 4 when the electronic locking component 3 returns to the locked position. That is, the dial block 4 being in the limited position will not interfere with the normal operation of the electronic locking component 3. The dial block 4 serves as a manual unlocking mechanism. In this utility model, when the locking component 2 is locked by the electronic locking component 3 and the electronic locking component 3 is in a de-energized state, the rotary combination lock 5 can also remove the limit on the dial block 4 by rotating the knob 501. At this time, moving one end of the dial block 4 can cause the dial block 4 to drive the electronic locking component 3 to unlock the locking component 2, thereby avoiding the situation where the electronic locking component 3 cannot unlock the locking component 2 after the power is cut off.

[0055] In one embodiment of this utility model, the electronic locking assembly 3 includes a locking member 301 and a driving member 302. The locking member 301 is movably disposed within the lock housing 1. The other end of the lever 4 abuts against one side of the locking member 301 to push the locking member 301 to unlock the upper locking member 2. The driving member 302 is connected to the locking member 301 to drive the locking member 301 to lock or unlock the upper locking member 2. Specifically, the locking member 301 is slidably disposed within the lock housing 1 and can slide back and forth within the lock housing 1. The driving member 302 is fixedly disposed within the lock housing 1, and one end of the driving member 302 is connected to one side of the locking member 301. After the driving member 302 is activated, it will drive the locking member 301 to slide back and forth within the lock housing 1, thereby locking or unlocking the upper locking member 2 inserted into the lock housing 1. When the locking member 301 slides towards the unlocked position, it separates from the lever 4. When the locking member 301 is in the locked position, it abuts against the side of the lever 4 closest to the unlocked position. Preferably, in this embodiment, the driving member 302 can be threadedly connected to the locking member 301. For example, one end of the driving member 302 has a rotatable screw (not shown), and the locking member 301 has a threaded hole (not shown). The driving member 302 drives the locking member 301 to move back and forth by rotating the screw in the forward or reverse direction.

[0056] like Figure 6 As shown, further, the locking member 301 includes a slider 3011, which is slidably disposed in the lock box 1. One end of the driving member 302 is fixedly connected to the slider 3011 to drive the slider 3011 to slide and lock or unlock the upper locking member 201. The other end of the lever 4 abuts against one side of the slider 3011. Specifically, the end of the driving member 302 connected to the slider 3011 can move within the lock box 1 to drive the slider 3011 to slide and lock or unlock the upper locking end 201. Figure 2 As shown, the left end of the driving component 302 is fixedly disposed in the lock box 1, and the right end of the driving component 302 is fixedly connected to the left end of the slider 3011. The driving component 302 is used to drive the slider 3011 to move back and forth. When one end of the locking component 2 extends into the lock box 1, the driving component 302 drives the slider 3011 to move to the left to the locked position, thereby locking the locking component 2 and preventing the locking component 2 from being pulled out of the lock box 1. If the driving component 302 drives the slider 3011 to move to the right, the locking component 2 is in the unlocked state and can be pulled out of the lock box 1.

[0057] Furthermore, both ends of the spring 3012 are connected to the slider 3011 and the inner wall of the lock box 1, respectively. When the slider 3011 is in the locked position, the spring 3012 is in a natural state. When the slider 3011 is in the unlocked position, the spring 3012 is in a compressed state. One end of the driving member 302 abuts against the slider 3011 to drive the slider 3011 to slide to the unlocked position or release the slider 3011 in the unlocked position.

[0058] Specifically, one end of the spring 3012 is fixedly connected to the end of the slider 3011 near the unlocking position, and the other end of the spring 3012 is fixedly connected to the inner wall of the lock box 1. The spring 3012 is used to reset the slider 3011. In this embodiment, one end of the driving member 302 abuts against the end of the slider 3011 with the latch 3013, and the end of the driving member 302 that abuts against the slider 3011 can move within the lock box 1. The movable end of the driving member 302 is only used to push the slider 3011 to unlock the upper locking member 2. For example, when the locking member 2 is in the locked state, the slider 3011 is in the locked position, and the spring 3012 is in a naturally relaxed state. When it is necessary to unlock the locking member 2, the movable end of the driving member 302 pushes the slider 3011 towards the direction of the spring 3012, and the slider 3011 compresses the spring 3012 during the movement. When the slider 3011 slides to the unlocked position, the movable end of the driving member 302 stops moving, and the spring 3012... When the lock is in a compressed state, the locking member 2 can be removed from the lock box 1. After the locking member 2 is removed, the movable end of the driving member 302 moves back to reset. At this time, the spring 3012 will gradually recover its deformation and push the slider 3011 towards the locking position through its elastic force. When the movable end of the driving member 302 has completed its reset, the slider 3011 returns to the locking position, and the spring 3012 recovers its deformation and returns to its naturally relaxed state. At this time, the ring lock is in the lock-up state.

[0059] When the ring lock is in the lock-to-lock state, if it is necessary to relock the locking member 2, simply grasp the locking member 2 and insert it into the lock box 1 through the lock hole 101. During the insertion of the locking member 2 into the lock box 1, the end of the locking member 2 first presses the slider 3011. At this time, the slider 3011 moves and slightly compresses the spring 3012. When the locking member 2 continues to extend until the part of the locking member 2 locked by the slider 3011 corresponds to the slider 3011, the spring 3012 restores its deformation and pushes the slider 3011 to slide, so that the slider 3011 returns to the locked position.

[0060] like Figure 7 As shown, one end of the locking member 2 is provided with a locking end 201 that can freely enter and exit the lock box 1. The locking end 201 is provided with a slot 2011, and the slider 3011 is provided with a latch 3013. The slider 3011 and the locking end 201 are locked by the engagement of the latch 3013 and the slot 2011. Specifically, during the process of the locking end 201 being inserted into the lock box 1, the end of the locking end 201 away from the locking member 2 first presses the latch 3013 on the slider 3011. At this time, the slider 3011 slightly compresses the spring 3012. When the locking end 201 continues to extend until the slot 2011 and the latch 3013 are aligned, the spring 3012 restores its deformation and pushes the slider 3011 to slide, causing the latch 3013 to engage in the slot 2011. At this time, the slider 3011 returns to the locked position to complete the locking.

[0061] Furthermore, the locking end 201, which is away from the locking member 2, has a round tip at one end. The slot 2011 is located at the end of the round tip that is close to the locking member 2. The side of the slot 3013 has a curved inclined surface that matches the round tip. The locking end 201 can press the slider 3011 by the cooperation between the round tip and the curved inclined surface.

[0062] like Figure 8 and Figure 9 As shown, in one embodiment of this utility model, the slider 3011 is hollow inside and has a groove 3014 on its top side. The lever 4 is provided with a slide rail 401. The other end of the lever 4 is movably disposed inside the slider 3011 and abuts against the side of the slider 3011 near the spring 3012. The slide rail 401 is slidably disposed in the groove 3014. Specifically, the bottom end of the lever 4 is movably disposed inside the slider 3011. When the slider 3011 is in the locked position and the lever 4 is in the limited position, the lever 4 abuts against the side of the slider 3011 near the spring 3012. The opening direction of the groove 3014 is consistent with the sliding direction of the slider 3011. When the lever 4 slides, it pushes the slider 3011 to slide simultaneously through the baffle 403. The slider 3011 can slide relative to the lever 4 through the cooperation of the slide rail 401 and the groove 3014.

[0063] Furthermore, the slider 3011 is provided with a guide hole 3015 on the side connected to the spring 3012, and the toggle block 4 is provided with a guide rod 402 on one side. The guide rod 402 is slidably disposed in the guide hole 3015. The cooperation between the guide hole 3015 and the guide rod 402 guides the sliding of the toggle block 4.

[0064] like Figure 10 As shown, the driving component 302 includes a motor 3021 and a push rod 3022. The motor 3021 is fixedly installed in the lock box 1, and one end of the motor 3021 is provided with a spiral shaft 3023. One end of the push rod 3022 has an internal thread section 3024 and is threadedly connected to the spiral shaft 3023 through the internal thread section 3024. The other end abuts against the slider 3011. The motor 3021 drives the push rod 3022 to slide through the spiral shaft 3023.

[0065] Specifically, the motor 3021 serves as the power source and is a DC servo motor 3021. The motor 3021 is fixedly mounted inside the lock box 1 with high-strength bolts. The lock box 1 also contains shock-absorbing rubber pads to effectively reduce vibration and noise generated during motor 3021 operation. One end of the motor 3021 has a helical shaft 3023, which is made of high-strength alloy steel and has undergone precision grinding and polishing. The helical shaft 3023 is connected to the output shaft of the motor 3021 via a spline. This connection method not only transmits a large torque but also provides good alignment, ensuring that the helical shaft 3023 will not become eccentric during high-speed rotation. One end of the push rod 3022 has an internal thread section 3024, which forms a high-precision threaded pair with the external thread of the helical shaft 3023. One end of the push rod 3022 adopts a hollow cylindrical structure to reduce its weight while ensuring sufficient strength. It is made of aluminum alloy and anodized, providing good wear resistance and corrosion resistance. The other end of the push rod 3022 abuts against the slider 3011, or, when the push rod 3022 is in its initial position, there is a gap between the other end of the push rod 3022 and the slider 3011 to prevent the spring 3012 from pushing the slider 3011 back to its original position and impacting the push rod 3022 when the ring lock is in the locking state and the locking end 201 is locking. During operation, the motor 3021 drives the push rod 3022 to slide via the helical shaft 3023. Under the action of the helical transmission principle, the push rod 3022 will move linearly along the axial direction of the helical shaft 3023. When the motor 3021 rotates forward, the push rod 3022 extends forward and pushes the slider 3011 to move; when the motor 3021 rotates in reverse, the push rod 3022 retracts backward, releasing the slider 3011 and the spring 3012. At this time, the spring 3012 restores its deformation and drives the slider 3011 to reset.

[0066] like Figure 11 and Figure 12As shown, the electronic locking assembly 3 further includes a PCB board and a wireless communication module 304. The PCB board is disposed in the lock box 1 and electrically connected to the motor 3021 for starting and stopping the motor 3021. The wireless communication module 304 is disposed in the lock box 1 and electrically connected to the PCB board for receiving and transmitting locking or unlocking signals from an external mobile terminal to the PCB board.

[0067] Specifically, the PCB board is fixedly installed inside the lock box 1 and electrically connected to the electronic locking component 3. It controls the electronic locking component 3 to lock or unlock the locking end 201 extending into the lock box 1. The wireless communication module 304 is installed inside the lock box 1 and electrically connected to the PCB board. It establishes a wireless communication connection with an external mobile terminal, receiving and transmitting unlocking and unlocking signals from the mobile terminal. The wireless communication module 304 includes one or more of Bluetooth, WiFi, and NFC modules. That is, the wireless communication module 304 can be a standalone NFC module or an integration of Bluetooth, WiFi, and NFC modules. Users can establish a communication connection with the wireless communication module 304 via a mobile terminal to control the electronic locking component to lock or unlock the locking end 201. Users must enter the original password or a modified password when establishing a communication connection with the wireless communication module 304 via their mobile terminal to prevent others from easily establishing a communication connection with the ring lock. The ring lock provided by this utility model establishes a communication connection with the user's mobile terminal through a wireless communication module 304. For example, the user establishes a communication connection with the ring lock using a mobile phone. When the user locks or unlocks the lock on the mobile terminal, the mobile terminal transmits the locking or unlocking signal to the PCB board through the wireless communication module 304. After receiving the signal, the PCB board controls the electronic locking component 3 to lock or unlock the locking end 201 inserted into the lock box 1. The ring lock in this utility model uses wireless communication for locking or unlocking, which is more secure than traditional ring locks with a keyhole structure and can prevent it from being cracked by lock picking tools.

[0068] Furthermore, the ring lock also includes a keypad 6, which is located on the outside of the lock box 1 and electrically connected to the PCB board. Users can also enter a numeric password through the keypad 6 to unlock the electronic locking component 3.

[0069] In one embodiment of this utility model, the ring lock further includes a battery 7 and a limit switch 8. Both the limit switch 8 and the battery 7 are disposed inside the lock box 1 and are electrically connected to the PCB board. The battery 7 provides power. The limit switch 8 is provided with a sliding contact rod 801 for triggering the limit switch 8. One end of the contact rod 801 is fixedly connected to the push rod 3022. When the push rod 3022 pushes the toggle block 4 to the unlock position, the contact rod 801 triggers the limit switch 8 and controls the motor 3021 to stop running. When the push rod 3022 returns to the initial position, the contact rod 801 triggers the limit switch 8 again and controls the motor 3021 to stop running. The limit switch 8 protects the internal structure of the ring lock.

[0070] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0071] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0072] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0073] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0074] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0075] Of course, the above description of the embodiments of this utility model is quite detailed, but it should not be construed as a limitation on the scope of protection of this utility model. This utility model may have other various implementations. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model. The scope of protection of this utility model is subject to the appended claims.
