Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of locks, in particular to a theftproof chain and a horseshoe lock. BACKGROUND

[0002] A horseshoe lock is a U-shaped or D-shaped lock made of high-strength alloy steel. Its lock body and lock beam form a closed structure similar to a horseshoe shape (U-shaped cross section), hence the name "horseshoe lock". The lock is mainly used for anti-theft of electric vehicles, bicycles, motorcycles and other vehicles, and can also be used for protection of fixed facilities such as shop door frames. In use, the lock beam passes through the vehicle wheel, frame or other fixed objects and is firmly closed with the lock body, preventing the vehicle from being directly pushed or moved away through its strong metal structure, thereby improving the security of anti-theft.

[0003] To further enhance the anti-theft performance, a metal chain is often attached to the horseshoe lock in the prior art. The chain is usually connected to the lock body and can be wound around the vehicle body and surrounding fixed objects (such as railings, posts, etc.), forming a more secure restraint. This combination of horseshoe lock and chain not only increases the difficulty of breaking the lock itself, but also effectively prevents the vehicle from being dragged away as a whole, so it is widely used in high-security scenarios such as logistics storage and long-term parking.

[0004] However, the anti-theft chain in the prior art is usually a mechanical structure. In actual application, if the user is nearby but cannot directly see the vehicle, the user cannot know the situation in time even if the chain is damaged, cut or abnormally moved. SUMMARY

[0027] In one embodiment, the connecting portion is provided on both sides of the beginning end of the chain body;

[0028] The first protective sleeve has second connecting holes on both sides of one end near the beginning of the chain body, and the second connecting holes cooperate with the corresponding connecting parts;

This allows the chain to activate the alarm and disable the standby monitoring function when it is disconnected from the horseshoe lock body, saving energy. When the chain is connected to the horseshoe lock body (to enhance anti-theft performance), the alarm is activated to start the standby monitoring function and enter standby mode. Therefore, if the chain is damaged, cut, or moves abnormally, the alarm immediately sounds, allowing the user to be promptly notified of any abnormalities. This effectively enhances the reliability and responsiveness of the anti-theft chain, thereby improving its anti-theft performance.

[0058] 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.

[0059] See Figures 1-7 This invention illustrates a preferred embodiment of an anti-theft chain, comprising:

[0060] Chain body 1;

[0061] Connecting component 2 is disposed at the beginning of the chain body 1. Connecting component 2 is used to detachably engage with the first connecting hole 501 on the horseshoe lock body 50 to connect the chain body 1 and the horseshoe lock body 50 together.

[0062] An alarm (not shown in the figure) is installed on the chain body 1. The alarm is used to monitor whether the chain body 1 is abnormally damaged and to issue an alarm signal when the chain body 1 is abnormally damaged. The alarm signal can be an audible alarm signal or an audible and visual alarm signal.

[0063] Sensor 4 is mounted on the chain body 1 and is electrically connected to the alarm.

[0064] Magnetic component 5 is movably disposed on connecting component 2, and magnetic component 5 can switch between a first position and a second position by means of movement;

[0065] When the magnetic component 5 is in the first position, the connecting component 2 is disengaged from the first connecting hole 501, and the magnetic component 5 is misaligned with the sensor 4, so as to trigger the alarm to turn off the standby monitoring function. That is, when the anti-theft chain is disengaged from the horseshoe lock body 50, the alarm on the anti-theft chain is controlled to turn off the standby monitoring function, so as to save power.

[0066] When the magnetic component 5 is in the second position, the connecting component 2 engages with the first connecting hole 501, and the magnetic component 5 abuts against the horseshoe lock body 50, causing the magnetic component 5 to move until at least part of it is aligned with the sensor 4, thereby triggering the alarm to activate the standby monitoring function. That is, when the anti-theft chain is connected to the horseshoe lock body 50 (to enhance anti-theft performance), the alarm on the anti-theft chain is controlled to activate the standby monitoring function, so that when the anti-theft chain is damaged, cut, or abnormally moved, an alarm can be triggered in a timely manner, ensuring that the user is promptly notified of any abnormalities, ultimately enhancing anti-theft performance; and

[0067] The elastic component 6 is disposed between the chain body 1 and the magnetic component 5. The elastic component 6 is used to provide a thrust to the magnetic component 5 so that the magnetic component 5 maintains the first position.

[0068] The anti-theft chain of the present invention integrates an alarm, a sensor 4, a magnetic component 5, and an elastic component 6 on the chain body 1, which connects the lock body 50 to the vehicle body and surrounding fixed objects (such as railings, posts, etc.). This allows the chain to activate the alarm and disable the standby monitoring function when it is disconnected from the horseshoe lock body 50, thus saving energy. When the anti-theft chain is connected to the horseshoe lock body 50 (to enhance anti-theft performance), the alarm is activated to start the standby monitoring function and enter a standby state. Therefore, when the anti-theft chain is damaged, cut, or abnormally moved, the alarm immediately sounds, allowing the user to be promptly notified of any abnormalities. This effectively enhances the reliability and responsiveness of the anti-theft chain, thereby improving its anti-theft performance.

[0069] Specifically, when using an anti-theft chain to enhance anti-theft performance, the first end of the chain body 1 engages with the first connecting hole 501 of the lock body 50 via the connecting component 2, connecting the anti-theft chain to the lock body 50. At this time, the lock body 50 abuts against the magnetic component 5, pushing the magnetic component 5 to move until at least a portion of the magnetic component 5 aligns with the sensor 4, while compressing the elastic component 6, causing the elastic component 6 to accumulate potential energy. This alignment state triggers the alarm to activate the standby monitoring function. Once the anti-theft chain is damaged, cut, or moves abnormally, the alarm immediately issues an alarm signal. When the anti-theft chain is not used, the anti-theft chain separates from the horseshoe lock body 50, the lock body 50 no longer abuts against the magnetic component 5, the elastic component 6 releases potential energy and pushes the magnetic component 5 to move, causing the magnetic component 5 to misalign with the sensor 4, thereby triggering the alarm to deactivate the standby monitoring function.

[0070] Specifically, the magnetic component 5 can be any one of a magnet, an electromagnet, etc., and the sensor 4 can be any one of a Hall sensor, a magnetoresistive sensor, etc.

[0071] Understandably, when enhanced anti-theft performance is required, the chain body 1 can wrap around the vehicle body or surrounding fixed objects (such as railings, posts, etc.). The first end of the chain body 1 passes through the connecting ring 70 set at the tail end of the chain body 1, and then the first end of the chain body 1 is connected to the lock body 50 through the connecting component 2, thereby forming multiple constraints on the vehicle and effectively preventing the vehicle from being towed away as a whole.

[0072] It is understandable that the activation, deactivation, and alarm signal issuance of the standby monitoring function can all be referenced from the patent documents previously filed by the same applicant, and will not be elaborated here.

[0073] See Figure 5 In one embodiment, the anti-theft chain further includes:

[0074] The anti-theft wire 7 has one end electrically connected to the alarm, and the other end extends from the beginning to the end of the chain body 1, thus forming a continuous conductive monitoring loop along the length of the chain body 1. The alarm is also configured to emit an alarm signal in response to the disconnection of the anti-theft wire 7. Thus, when the anti-theft chain is in normal use, the anti-theft wire 7 loop remains connected, and the alarm is in standby monitoring mode. When the chain body 1 is cut or severed, the anti-theft wire 7 is simultaneously severed, causing the conductive loop to break (signal interruption). Upon receiving this loop disconnection signal, the circuit board 40 (electrically connected to the anti-theft wire 7 and the alarm) controls the alarm to emit an audible or visual alarm signal. Therefore, the anti-theft wire 7, in conjunction with the aforementioned magnetic component 5 and sensor 4 detection mechanism, forms a multi-layered anti-theft alarm, further enhancing the anti-theft performance.

[0075] See Figures 1-5 In one embodiment, the anti-theft chain further includes:

[0076] The first protective sleeve 8 is fitted onto the chain body 1, extending from the beginning to the end of the chain body 1 to form a continuous, closed outer wrapping layer. The first protective sleeve 8 covers the anti-theft wire 7, concealing it within the anti-theft chain, making it difficult for thieves to detect and thus increasing the difficulty of predicting theft. Furthermore, the first protective sleeve 8 provides a physical barrier for the internal anti-theft wire 7, effectively preventing accidental scratches, corrosion, or targeted damage from external objects, ensuring the long-term stability of this monitoring circuit. Additionally, the first protective sleeve 8 also protects the chain body 1, preventing rust and corrosion and ensuring the long-term structural stability of the anti-theft chain.

[0077] Specifically, in one embodiment, the first protective sleeve 8 can be made of any of the following materials: nylon, Oxford cloth, canvas, etc.

[0078] See Figures 1-5 In one embodiment, the anti-theft chain further includes:

[0079] The first mounting base 9 is disposed on the head end of the chain body 1, and the first mounting base 9 has a first mounting cavity 93;

[0080] The second mounting base 10 is installed inside the first mounting cavity 93 and carries the alarm and sensor 4. Because the first mounting base 9 is located at the head end of the chain body 1 and integrates the first mounting cavity 93 to accommodate the second mounting base 10 carrying the alarm and sensor 4, the alarm and sensor 4 are reliably fixed to the chain body 1. Simultaneously, since the alarm and sensor 4 are integrated inside the first mounting base 9, they are hidden within the anti-theft chain, making them difficult to detect. This makes it harder for thieves to visually identify that the anti-theft chain has an alarm function, thus increasing the difficulty of predicting theft. Furthermore, the first mounting base 9 provides a physical isolation barrier for the internal alarm and sensor 4, effectively preventing accidental scratches, corrosion, or targeted damage from external objects, ensuring the long-term operational stability of the alarm function. In addition, the first mounting base 9 also protects the alarm and sensor 4, preventing rust and corrosion and ensuring the long-term structural stability of the alarm and sensor 4. In addition, the second mounting base 10 serves to support the alarm and sensor 4, forming a modular alarm device that is easy to assemble.

[0081] See Figures 1-5 In one embodiment, the first mounting base 9 is sleeved on the head end of the chain body 1. To reduce installation difficulty, the first mounting base 9 includes:

[0082] The first base 91 is disposed on one side of the beginning end of the chain body 1; and

[0083] The second base 92 is disposed on the other side of the first end of the chain body 1. The second base 92 is connected to the first base 91, and the second base 92 and the first base 91 form a first mounting cavity 93.

[0084] In one embodiment, the first base 91 is provided with a first buckle 912, and the second base 92 is provided with a second buckle (not shown in the figure). The second buckle engages with the first buckle 912 to achieve a stable and quick connection between the second base 92 and the first base 91.

[0085] Of course, in other embodiments, the first base 91 and the second base 92 can also be connected together by any kind of fastener such as bolts, screws, or rivets.

[0086] See Figures 1-5 In one embodiment, the first protective sleeve 8 has a second connecting hole (not shown in the figure) at one end near the beginning of the chain body 1;

[0087] The first end of the chain body 1 is provided with a connecting part 11, which cooperates with the second connecting hole. That is, the connecting part 11 is inserted into the second connecting hole to connect the first protective sleeve 8 to the chain body 1, thereby realizing the first protective sleeve 8 being firmly fixed to the chain body 1.

[0088] In one embodiment, connecting portions 11 are provided on both sides of the beginning end of the chain body 1;

[0089] The first protective sleeve 8 has second connecting holes on both sides of one end near the beginning of the chain body 1. The second connecting holes cooperate with the corresponding connecting parts 11 to improve the connection stability between the first protective sleeve 8 and the chain body 1.

[0090] The first mounting base 9 is fitted onto the end of the first protective sleeve 8 near the head end of the chain body 1. That is, the first mounting base 9 covers the end of the first protective sleeve 8 near the head end of the chain body 1, preventing thieves from damaging the connection between the first protective sleeve 8 and the chain body 1, thereby further improving the reliability of the connection between the first protective sleeve 8 and the chain body 1.

[0091] The first base 91 has a third connecting hole 911, which cooperates with the corresponding connecting part 11 to connect the first base 91 to the chain body 1, thereby firmly fixing the first base 91 to the chain body 1.

[0092] The second base 92 has a fourth connecting hole (not shown in the figure). The fourth connecting hole cooperates with the corresponding connecting part 11 to connect the second base 92 to the chain body 1, thereby firmly fixing the second base 92 to the chain body 1 and ensuring that the first mounting base 9 is firmly fixed to the chain body 1.

[0093] See Figures 1-5 In one embodiment, the anti-theft chain further includes:

[0094] The movable component 20 is movably disposed on the connecting component 2, and the movable component 20 passes through the first mounting cavity 93, and the movable component 20 carries the magnetic component 5;

[0095] The elastic component 6 is disposed between the chain body 1 and the movable component 20. That is, the magnetic component 5 is not directly mounted on the connecting component 2, but is disposed on the movable component 20, which is movably disposed on the connecting component 2. Thus, the magnetic component 5 is indirectly and movably disposed on the connecting component 2. This structural design allows the magnetic component 5 to be of a smaller and more economical size without affecting its alignment reliability with the sensor 4, thereby directly reducing costs. In addition, the elastic component 6 acts directly on the movable component 20, providing balanced buffering and restoring force for the movement of the magnetic component 5. This structural design avoids rigid collisions and friction between the magnetic component 5 and the connecting component 2 or the lock body 50, reducing wear and thus extending service life.

[0096] See Figure 5 In one embodiment, the movable part 20 has a mounting hole 201, and the magnetic part 5 is embedded in the mounting hole 201 to reliably fix the magnetic part 5 to the movable part 20. At the same time, the magnetic part 5 is prevented from occupying the external space of the movable part 20, which is more conducive to the compact design of the anti-theft chain.

[0097] See Figure 2 and Figure 6 In one embodiment, the first mounting base 9 has a first guide channel 94, which communicates with the first mounting cavity 93;

[0098] The second mounting base 10 has a second guide channel 104, which is connected to the first guide channel 94 and is coaxially arranged with the first guide channel 94.

[0099] The movable component 20 is slidably traversed through the first guide channel 94 and the second guide channel 104. This arrangement of the first guide channel 94 and the second guide channel 104 provides the movable component 20 with a longer, more constrained, and precise linear motion trajectory. This effectively prevents radial offset or jamming of the movable component 20 during sliding, ensuring that the magnetic component 5 can accurately and repeatably reach the preset position aligned or misaligned with the sensor 4, thereby effectively improving the reliability of the trigger signal. Furthermore, the continuous and coaxial first guide channel 94 and second guide channel 104 provide smooth, continuous support for the movable component 20, avoiding potential steps, misalignments, or abrupt frictional changes when crossing the joint between two independent components. This reduces sliding resistance and wear, resulting in smoother sliding of the movable component 20 and contributing to improved mechanical lifespan and long-term stability.

[0100] In one embodiment, the elastic component 6 and the movable component 20 are both sleeved on the connecting component 2, so that the connecting component 2, the elastic component 6 and the movable component 20 are coaxially arranged to form a compact module, which is conducive to the compact design of the anti-theft chain; in addition, the sliding of the movable component 20 and the extension and retraction of the elastic component 6 are forcibly constrained on the same connecting component 2, which fundamentally eliminates the problem of uneven wear, jamming or malfunction caused by component misalignment.

[0101] In one embodiment, the elastic member 6 is specifically a spring; of course, in other embodiments, the elastic member 6 may also be an elastic rubber sleeve or a spring sheet structure.

[0102] For easy installation of alarms and sensors 4, please refer to [link / reference]. Figures 5-7 In one embodiment, the second mounting base 10 includes:

[0103] Third matrix 101;

[0104] A fourth base 102 is connected to a third base 101. The fourth base 102 has a second mounting cavity (not shown in the figure) that accommodates a circuit board 40, an alarm and a sensor 4 disposed on the circuit board 40; and

[0105] Cover 103 is disposed on the fourth base 102 and covers the opening of the second mounting cavity to encapsulate the circuit board 40, the alarm and the sensor 4 inside the second mounting base 10.

[0106] To facilitate charging of the circuit board 40, the second substrate 92 has a charging port 921, which is connected to the charging interface of the circuit board 40.

[0107] See Figures 1-5 The anti-theft chain also includes:

[0108] The second protective cover 30 is detachably fitted onto the first mounting base 9 and covers the charging port 921 to provide dust and water protection.

[0109] In one embodiment, the second protective sleeve 30 may be made of rubber or plastic.

[0110] See Figures 8-9 This invention illustrates a horseshoe lock according to a preferred embodiment, comprising:

[0111] Lock body 50, the lock body 50 has a first connecting hole 501;

[0112] Locking beam 60, movably mounted on lock body 50; and

[0113] The aforementioned anti-theft chain has a detachable connection between the connecting component 2 and the first connecting hole 501.

[0114] In one embodiment, the alarm is built into the third substrate 101. The alarm may be a buzzer or other component that can realize sound alarm or sound and light alarm.

[0115] The horseshoe lock of the present invention, by employing the aforementioned anti-theft chain, integrates an alarm, a sensor 4, a magnetic component 5, and an elastic component 6 on the chain body 1 connecting the lock body 50 to the vehicle body and surrounding fixed objects (such as railings, posts, etc.). This allows the alarm to be triggered and the standby monitoring function to be disabled when the anti-theft chain is disconnected from the horseshoe lock body 50, thus saving energy. When the anti-theft chain is connected to the horseshoe lock body 50 (to enhance anti-theft performance), the alarm is triggered to activate the standby monitoring function and enter a standby state. Therefore, when the anti-theft chain is damaged, cut, or abnormally moved, the alarm immediately emits an alarm signal, enabling the user to be promptly notified of any abnormalities. This effectively enhances the reliability and responsiveness of the anti-theft chain, thereby strengthening its anti-theft performance.

[0116] The connections mentioned in this invention are divided into fixed connections and detachable connections. Fixed connections are non-detachable connections, including but not limited to conventional fixed connection methods such as folded connections, riveted connections, adhesive connections, and welded connections. Detachable connections include but not limited to conventional disassembly methods such as threaded connections, snap-fit ​​connections, pin connections, and hinged connections. When a specific connection method is not explicitly specified, it is assumed that at least one connection method can always be found among existing connection methods to achieve the function, and those skilled in the art can choose according to their needs. For example, a welded connection can be selected for fixed connections, and a hinged connection can be selected for detachable connections.
