Abstract

This invention discloses an anti-theft alarm fastener. By integrating a position detection module, a control module, and an alarm module into the male and female buckles of an existing magnetic fastener, it achieves real-time monitoring of the fastener's connection status and automatic alarm functions upon unauthorized separation. The control module, with its function selection button, allows the fastener to flexibly switch between at least two operating modes: alarm function off or on.

Description

Technical Field

[0001] This invention relates to the field of fastener technology, and more specifically, to an anti-theft alarm fastener. Background Technology

[0002] Buckles, as a common type of connector, are widely used in various items that require detachable connections, such as bags, backpacks, clothing, outdoor equipment, and display merchandise. Their basic function is to facilitate the easy connection and separation of two parts.

[0003] However, in specific application scenarios such as bicycle lights, phone clips, and bicycle bags, ordinary fasteners only provide physical connection functions, allowing users to quickly install and remove them, but they cannot effectively prevent theft, thus increasing the risk of theft. For example, if a user detachably attaches a bicycle light to their bicycle and leaves it behind, someone else may easily remove and take it.

[0004] To prevent theft, existing solutions typically involve adding complex designs to the buckles, making their opening mechanism difficult to detect. This prevents unsuspecting third parties from easily opening the buckles and taking the items. For example, adding an extra cover obscures the actual operating part of the buckle used for unlocking, making it impossible for others to see. The actual operating part is only revealed when the cover is removed in a specific way, allowing for unlocking. This anti-theft structure relies on the mechanical structure of the buckle, increasing its complexity and making it more difficult for users to unlock. Therefore, it sacrifices convenience for enhanced security, and this anti-theft solution still needs improvement. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned shortcomings by providing an anti-theft alarm buckle.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This invention provides a burglar alarm buckle, which includes:

[0008] First connection module;

[0009] A second connection module, which can be detachably engaged with the first connection module;

[0010] A position detection module, which is disposed in the first connection module and / or the second connection module, is used to detect the separation state of the first connection module and the second connection module;

[0011] A control module is disposed in the second connection module, electrically connected to the position detection module and receiving the detection signal from the position detection module;

[0012] An alarm module is installed in the first connection module or the second connection module and is electrically connected to the control module;

[0013] When the position detection module detects that the first connection module and the second connection module are separated, the control module can control the alarm module to sound an alarm.

[0014] Furthermore, the control module is equipped with a function selection button, which is movably disposed in the second connection module and partially exposed to the second connection module, so that the user can operate it to switch functions;

[0015] When the first function is activated, the alarm module does not trigger an alarm.

[0016] In the second function, the control module can control the alarm module to sound an alarm based on the position signal detected by the position detection module.

[0017] Furthermore, one of the first connecting module and the second connecting module is a male buckle, and the other is a female buckle;

[0018] The male buckle is provided with a locking tongue;

[0019] The female buckle is provided with a locking hole;

[0020] The male buckle can be inserted into the lock hole through the latch along the first direction and can be separably engaged with the female buckle;

[0021] The latch is recessed in a second direction along the first direction, and the female buckle is provided with a locking assembly that can move along the second direction and is at least partially movable into the lock hole.

[0022] When the latch is inserted into the lock hole in the first direction, the locking assembly can move in the second direction and partially extend into the lock hole and embed itself in the lock groove to engage with the lock groove. The position detection module detects the position signal of the engagement state of the male buckle and the female buckle.

[0023] When the locking assembly is disengaged from the lock groove and the bolt is pulled out of the lock hole by operation, the position detection module detects the separation state of the male and female latches, and the control module can control the alarm module to sound an alarm.

[0024] Furthermore, the position detection module includes:

[0025] A trigger element is disposed in the male buckle;

[0026] A sensor element, disposed in the female buckle, is used to sense changes in the position of the trigger.

[0027] Furthermore, the male buckle is provided with a mounting groove that protrudes along the first direction, the mounting groove is located on the side of the latch, and the trigger is disposed in the mounting groove;

[0028] The female buckle is provided with a positioning groove that is correspondingly embedded in the mounting groove when the male buckle is engaged with the female buckle, and the sensor element is disposed in the female buckle relative to the positioning groove;

[0029] When the male buckle engages with the female buckle, the mounting groove and the positioning groove cooperate to position the relative positions of the trigger and the sensor element.

[0030] Furthermore, the trigger includes a magnetic element, and the sensor element includes a Hall sensor for sensing changes in magnetic field strength.

[0031] Furthermore, the female buckle includes a first panel and a second panel that are engaged with each other;

[0032] The first panel and the second panel are mated to form an accommodating cavity;

[0033] The first panel is provided with the lock hole and the mounting groove, and the sensor element is disposed in the accommodating cavity opposite to the mounting groove;

[0034] The control module and the alarm module are disposed within the accommodating cavity;

[0035] The locking assembly includes a locking member surrounding the outside of the lock hole and movable within the receiving cavity in the second direction, and a driving member for driving the locking member to move in the second direction and engage with the lock groove;

[0036] The locking member has a locking edge protruding from the inner ring facing the lock hole, and the locking edge can extend into or move out of the lock hole as the locking member moves;

[0037] When the latch is inserted into the lock hole in the first direction, the driving member drives the locking member to move in the second direction, causing the locking edge to extend into the lock hole and embed into the lock groove and engage with the lock groove.

[0038] Furthermore, the locking component is provided with an operating part, which protrudes from the outside of the female buckle, so that the user can operate the locking component to move in the opposite direction of the second direction engagement to drive the locking edge to disengage from the locking groove.

[0039] Furthermore, the driving element includes a first magnetic element;

[0040] The first magnetic element is fixedly disposed on the locking element. When the locking tongue is inserted into the lock hole in the first direction, it interacts with the magnetic attraction structure fixedly disposed in the male buckle to drive the locking element to move in the second direction, causing the locking edge to extend into the lock hole and be embedded in the lock groove and engage with the lock groove.

[0041] Furthermore, the male buckle is provided with a second magnetic element, and the female buckle is provided with a third magnetic element that attracts the second magnetic element, so that the male buckle and the female buckle are magnetically engaged and the bolt is guided to be inserted into the lock hole;

[0042] When the latch is inserted into the lock hole in the first direction, the first magnetic element and the second magnetic element interact to drive the locking element to move in the second direction, causing the locking edge to extend into the lock hole and embed into the lock groove and engage with the lock groove.

[0043] Compared with the prior art, the beneficial effects of the present invention are:

[0044] This invention integrates a position detection module, a control module, and an alarm module into the male and female buckles of existing magnetic fasteners, enabling real-time monitoring of the fastener's connection status and automatic alarm functions for unauthorized separation. When the male and female buckles are unauthorizedly separated, the position detection module sensitively senses the change in position and transmits the signal to the control module, which then activates the alarm module to issue an alarm. This design is simple in structure, highly reliable, and effectively issues an alarm when unauthorized separation occurs.

[0045] In addition, the control module features a function selection button, allowing the fastener to flexibly switch between at least two operating modes. In the first mode, the alarm function is off, and the fastener can be used as a regular fastener without affecting its basic connection functions. In the second mode, the alarm function is activated, and the fastener enters an alert state. This switchable mode design greatly enhances the product's practicality and applicability, solving the problem of existing alarm fasteners having limited functionality and being unusable in non-anti-theft scenarios, thus meeting the diverse needs of users in different situations.

[0046] Furthermore, the position detection module employs a magnetic trigger and a Hall sensor element to form a non-contact position detection module, avoiding the reliability issues caused by contact oxidation, wear, or poor contact in traditional mechanical switches. The Hall sensor determines the relative position of the male and female contacts by sensing changes in magnetic field strength, offering high detection accuracy, fast response speed, and long service life. Moreover, through the mating structure of the mounting groove and positioning recess, the relative position of the trigger and sensor element can be precisely guided and fixed when the male and female contacts engage, ensuring that the sensor is in the same sensing area after each engagement. This further improves the accuracy and consistency of detection, effectively avoiding misjudgments or missed detections caused by positional deviations.

[0047] The combination of male and female latches, along with the mechanical locking mechanism of the locking assembly and lock groove, achieves a stable and reliable physical connection. When the bolt is inserted into the lock hole, the locking assembly automatically engages in the lock groove, forming a secure lock and effectively preventing accidental separation due to vibration or accidental contact, thus reducing the false alarm rate. Simultaneously, this combination of mechanical locking and electronic detection ensures both structural stability and alarm reliability without compromising operational convenience. When separation is required, the user can disengage the locking assembly from the lock groove via the operating mechanism. At this point, the position detection module senses the change in status, and the control module can trigger an alarm according to a preset mode (under the second function), or not trigger an alarm under legitimate operation (under the first function), achieving a precise combination of locking engagement and illegal separation alarms.

Detailed Implementation

[0056] The invention will now be further described with reference to the accompanying drawings.

[0057] refer to Figure 1 and Figure 2 As shown, an embodiment of the present invention is an anti-theft alarm buckle, which includes a first connection module 10, a second connection module 20, a position detection module 30, a control module 40, and an alarm module 50;

[0058] The first connecting module 10 and the second connecting module 20 are configured to be separably joined together.

[0059] The position detection module 30 is disposed in the first connection module 10 and / or the second connection module 20, and is used to detect the separation state of the first connection module 10 and the second connection module 20. Its core function is to detect the relative position state between the first connection module 10 and the second connection module 20 in real time, non-contact or contact, that is, whether the two are in a separated state.

[0060] The control module 40 is located in the second connection module 20, electrically connected to the position detection module 30, and receives the detection signals from the position detection module 30. The control module 40 and the position detection module 30 are electrically connected via a flexible circuit board or wires. The control module 40 receives the raw detection signals from the position detection module 30 and processes and performs logical judgments. The core of the control module 40 can be a microcontroller (MCU), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), or a simple logic circuit composed of comparators and logic gates. It also integrates an interface for connecting to an external power supply or directly integrates a battery-powered component to power the entire alarm device.

[0061] The alarm module 50 is housed in either the first connection module 10 or the second connection module 20 and is electrically connected to the control module 40. The alarm module 50 can be selectively located in either the first connection module 10 or the second connection module 20, and electrically connected to the control module 40, depending on the product design and spatial layout requirements. Typically, the alarm module 50 and the control module 40 are housed in the same connection module—the second connection module 20. The alarm module 50 can be a piezoelectric buzzer, an electromagnetic speaker, a high-brightness light-emitting diode (LED), or a vibration motor, etc., used to emit a perceptible alarm signal such as sound, light, or vibration when triggered. In this embodiment, the alarm module 50 is a buzzer, which provides an alarm through a buzzing sound.

[0062] When the first connection module 10 is separated from the second connection module 20, the position detection module 30 can sense the change in the position signal and send the detection information to the control module 40. After receiving the signal, the control module 40 can drive the alarm module 50 to start according to its internal preset logic (for example, in the anti-theft mode, i.e., in the second function below), and issue a continuous or intermittent alarm, thereby playing the role of immediate warning and anti-theft.

[0063] This invention integrates a position detection module 30, a control module 40, and an alarm module 50 into an existing fastener to achieve real-time monitoring of the fastener's connection status and automatic alarm functions in case of unauthorized separation. When the fastener separates, the position detection module 30 can sensitively sense the change in position and transmit the signal to the control module 40, which can then activate the alarm module 50 to issue an alarm. This design is simple in structure, highly reliable, and effectively issues an alarm in case of unauthorized separation.

[0064] Furthermore, in some embodiments, such as Figure 1 and Figure 2 As shown, in order to improve the applicability of the product and the user experience, the control module 40 is provided with a function selection button 41. The function selection button 41 can be movably set in the second connection module 20 and partially exposed to the second connection module 20, so that the user can operate it to switch functions.

[0065] The function selection button 41 can be a micro switch or a tactile switch. The function selection button 41 is movably embedded in the housing of the second connection module 20, and its pressing or toggling part protrudes from the surface of the second connection module 20 for easy operation by the user.

[0066] The control module 40 has at least two operating modes that can be switched by the function selection button 41. In the first function, such as normal mode or off mode, the internal logic circuit of the control module 40 is set to ignore the separation signal from the position detection module 30. In this mode, regardless of how the first connection module 10 and the second connection module 20 are opened and closed, the control module 40 will not activate the alarm module 50, and the fastener is used only as a normal mechanical connector, suitable for application scenarios where an alarm is not required. For example, if the user needs to separate the first connection module 10 and the second connection module 20 and does not want to trigger an alarm, they can use the function selection button 41 to make the control module 40 operate in the first function.

[0067] In the second function, such as anti-theft mode or alert mode, the alarm monitoring function of control module 40 is activated. It monitors the signal from position detection module 30 in real time and continuously. Once a signal indicating separation is detected, control module 40 drives alarm module 50 to sound an alarm. In some embodiments, control module 40 can also delay the alarm for a short period of time (e.g., 1-2 seconds) after receiving the separation signal to avoid false alarms caused by momentary mis-triggered activation. For example, when a user needs to leave, the buckle can be put into the second function through function selection button 41. When others are unfamiliar with the function selection button, they will usually unlock it directly. At this time, the separation of first connection module 10 and second connection module 20 will trigger an alarm to remind the user or people around.

[0068] Furthermore, in some embodiments, the second function can also be set with two or more levels, which can be used to adjust the alarm mode of the control alarm module 50, such as emitting different levels of sound, flashing, or vibration.

[0069] This design allows the control module 40 to flexibly switch between at least two working modes via the function selection button 41. In the first mode, the alarm function is off, and the fastener can be used as a regular fastener without affecting its basic connection function. In the second mode, the alarm function is activated, and the fastener enters an alert state. This switchable mode design greatly enhances the product's practicality and applicability, solving the problem of existing fasteners having limited functionality and being unable to be quickly used in non-anti-theft scenarios, thus meeting the diverse needs of users in different situations. Users can set the fastener to different functional modes via the function selection button 41 according to the actual situation. This does not affect the fastener's quick-release and quick-installation characteristics, facilitating the quick removal and installation of items, while also meeting the needs of anti-theft scenarios and preventing theft.

[0070] It should be noted that the function selection button 41 is designed based on the characteristics of the buckle's usage scenarios. While it cannot prevent theft at its source, the function selection button 41 allows users to set the buckle to alarm mode for anti-theft alerts as needed. In this mode, although others might cancel the current alarm mode using the function selection button 41, most people, based on their usage habits, will ignore the function selection button 41 on the mechanical buckle and will operate the buckle to unlock it according to their usual habits. This is a habitual behavior. Therefore, if someone wants to steal items from the buckle, they will instinctively try to unlock it, triggering the alarm. When the alarm sounds, the thief will instinctively want to leave the scene quickly and is unlikely to try to turn off the alarm. As for the user, because they are familiar with the buckle's function and structure, they are not easily distracted by the alarm mode. Therefore, this design of the present invention enables the buckle to perform its anti-theft function and, in most cases, prevents the buckle from being illegally separated and items from being lost.

[0071] Furthermore, such as Figure 2-5 As shown, one of the first connecting module 10 and the second connecting module 20 is a male buckle and the other is a female buckle, and the two can be interchanged when specific design needs require.

[0072] The male buckle has a protruding latch 11, and the female buckle has a locking hole 21. The male buckle has the latch 11 integrally formed or fixed by fasteners. The female buckle has a locking hole 21 that corresponds to the shape and position of the latch 11. The engagement of the male and female buckles is achieved by inserting the latch 11 into the locking hole 21 along a preset first direction (perpendicular to the plane of the female buckle engagement).

[0073] The latch 11 has a recessed locking groove 111 along a second direction transverse to the first direction, and the female latch has a locking assembly 22 that can move along the second direction and is at least partially movable into the lock hole 21. Specifically, in order to form a lock and prevent the two from easily disengaging, the latch 11 has a recessed locking groove 111 along a second direction transverse to the first direction on its side wall. The locking groove 111 can be an annular groove surrounding the latch 11, or two independent grooves symmetrically arranged on both sides. Correspondingly, the female latch has a movable locking assembly 22. The locking assembly 22 is limited to moving only along the second direction, and at least a portion of it (such as the locking edge 2211 described below) can extend into the lock hole 21 during movement, and its shape corresponds to being able to be embedded in the locking groove 111 to form a mechanical interlocking structure.

[0074] When the latch 11 is inserted into the lock hole 21 in the first direction, the locking assembly 22 can be moved in the second direction by manual operation or a drive structure (such as the drive member 222 described below) and partially inserted into the lock hole 21 to engage with the lock groove 111. This latch-groove engagement forms a stable mechanical interlock, effectively preventing accidental separation due to vibration or accidental contact. In this engaged state, the position detection module 30 detects the position information indicating that the two are engaged.

[0075] When the locking assembly 22 is disengaged from the lock groove 111 and the bolt 11 is pulled out of the lock hole 21 by the operation, the position detection module 30 detects the separation state of the male and female latches, and the control module 40 can control the alarm module 50 to sound an alarm.

[0076] In this embodiment, the first connecting module 10 and the second connecting module 20 are specifically designed as a male and female buckle insertion structure, combined with the mechanical locking method of the locking assembly 22 and the lock groove 111, to achieve a stable and reliable physical connection. When the locking tongue 11 is inserted into the lock hole 21, the locking assembly 22 can be embedded into the lock groove 111 to form a firm lock, effectively preventing accidental separation due to vibration or accidental contact, thereby reducing the false alarm rate. At the same time, this combination of mechanical locking and electronic detection makes the fastener have both structural stability and alarm reliability. When separation is required, the user can disengage the locking assembly 22 from the lock groove 111 through the operating part. At this time, the position detection module senses the change in state, and the control module can trigger an alarm according to the preset mode (under the second function), or not trigger an alarm under legal operation (under the first function), realizing a precise combination of locking engagement and illegal separation alarm.

[0077] In some embodiments, such as Figure 2 As shown, in order to adopt non-contact detection technology and avoid the reliability problems caused by contact oxidation, wear, or poor contact in traditional mechanical switches, the position detection module 30 includes a trigger element 31 and a sensor element 32. The trigger element 31 is disposed in the male connector, and the sensor element 32 is disposed in the female connector.

[0078] The trigger element 31 serves as a signal source, and the sensor element 32 serves as the corresponding signal receiver, used to sense changes in the position of the trigger element 31. The trigger element 31 is fixedly disposed in the male buckle, while the sensor element 32 is fixedly disposed in the female buckle. When the relative position of the male and female buckles changes, the intensity or distribution of the physical field (such as magnetic field, electric field, or light field) generated by the trigger element 31 changes at the sensor element 32. The sensor element 32 senses this change and converts it into an electrical signal, which is transmitted to the control module 40, providing a signal basis for the control module 40 to control the alarm module 50.

[0079] Existing non-contact detection devices such as infrared beam sensors, magnetic field sensors, and photoelectric sensors can be used here.

[0080] In this embodiment, as Figure 2 As shown, in a preferred embodiment, the trigger 31 includes a magnetic element, and the sensor element 32 includes a Hall sensor for sensing changes in magnetic field strength.

[0081] The trigger element 31 uses a permanent magnet, such as a neodymium iron boron magnet. The sensor element 32 uses a Hall sensor. The working principle of the Hall sensor is based on the Hall effect: when a current-carrying conductor or semiconductor is placed in a magnetic field perpendicular to the direction of the current, a potential difference (Hall voltage) is generated across its terminals. The magnitude of this voltage is proportional to the product of the magnetic induction intensity and the current. Therefore, by detecting the change in Hall voltage, the change in magnetic field intensity can be accurately sensed, thereby determining the relative distance between the magnetic component (trigger element 31) and the Hall sensor (sensor element 32). When the male and female contacts are engaged, the trigger element 31 approaches the Hall sensor, generating a strong magnetic field, and the Hall sensor outputs a high voltage signal; when the two are separated, the magnetic field weakens, and the output voltage decreases. This non-contact detection method completely avoids the reliability problems caused by contact oxidation, wear, bounce, or poor contact in traditional mechanical switches, and has significant advantages such as high detection accuracy, fast response speed, and extremely long service life.

[0082] Of course, sensor element 32 here can also be a reed switch. A reed switch is a sealed contact composed of two reed tubes. When a magnetic field approaches, the contacts close; when the magnetic field moves away, the contacts open. Its advantages are low cost and simple circuit.

[0083] The sensor element 32 can also be a magnetoresistive sensor, such as anisotropic magnetoresistive sensor or giant magnetoresistive sensor, which has higher sensitivity than Hall sensor and can detect weaker magnetic field changes, making it suitable for applications with extremely high detection accuracy requirements.

[0084] Furthermore, in some embodiments, such as Figure 2-4 As shown, to further improve the accuracy, consistency, and anti-interference capability of the detection, the male buckle is provided with a mounting groove 12 protruding along the first direction and located on the side of the latch 11, and the trigger element 31 is disposed in the mounting groove 12. Correspondingly, the female buckle is provided with a positioning groove 23 into which the mounting groove 12 is correspondingly embedded when the male buckle and the female buckle are engaged, and the sensor element 32 is disposed in the female buckle relative to the positioning groove 23. When the male buckle and the female buckle are engaged, the mounting groove 12 and the positioning groove 23 cooperate to position the relative position of the trigger element 31 and the sensor element 32.

[0085] This groove-groove mating structure constitutes a precise mechanical guiding and positioning mechanism. It ensures that during each engagement, the trigger element 31 and the sensor element 32 achieve highly consistent and optimal relative positions in three dimensions, thereby minimizing detection inaccuracies caused by assembly tolerances, operational deviations, or component displacement after long-term use, achieving signal consistency and repeatability. Furthermore, it prevents the male and female latches from misaligning in the first direction, thus facilitating the insertion, locking, unlocking, and separation of the male and female latches.

[0086] In some embodiments, such as Figure 2 , Figure 5 and Figure 6 As shown, the female fastener includes a first panel 24 and a second panel 25 that mate with each other. The first panel 24 and the second panel 25 mate to form a receiving cavity. Specifically, the first panel 24 and the second panel 25 are mated together by ultrasonic welding, snap-fit, or screws, and together they enclose a hollow receiving cavity for accommodating functional components. This split design facilitates the installation and maintenance of internal components.

[0087] The first panel 24 has a lock hole 21 and a mounting groove 12. The sensor element 32 is disposed in the receiving cavity opposite to the mounting groove 12. The first panel 24, serving as the surface that mates with the male buckle, has a lock hole 21 for inserting the bolt 11 and a positioning groove 23 for engaging with the mounting groove 12 on the male buckle. The sensor element 32 is fixedly mounted in the receiving cavity (it can be integrated with the control module 40 onto a single circuit board), its position vertically opposite to the positioning groove 23 on the first panel 24, ensuring optimal sensing of the trigger element 31 embedded in the positioning groove 23. The control module 40 and the alarm module 50 are also housed and fixed in this receiving cavity, with highly integrated electronic components.

[0088] The locking assembly 22 includes a locking member 221 surrounding the outside of the lock hole 21 and movable within a receiving cavity in a second direction, and a driving member 222 for driving the locking member 221 to move in the second direction and engage with the lock groove 111. The locking member 221 has a protruding locking edge 2211 on its inner ring facing the lock hole 21, and the locking edge 2211 can extend into or out of the lock hole 21 as the locking member 221 moves.

[0089] The locking element 221 is generally annular or C-shaped, surrounding the outside of the lock hole 21. Its outer edge is confined within the receiving cavity and can only slide smoothly linearly in the second direction. The locking element 221 has an integrally protruding locking edge 2211 on its inner edge facing the lock hole 21. The thickness and shape of the locking edge 2211 match the locking groove 111 on the latch 11, and can extend into or completely retract from the lock hole 21 as the locking element 221 moves as a whole.

[0090] The function of the drive unit 222 is to drive the locking unit 221 to move in the second direction to achieve automatic locking.

[0091] When the latch 11 is inserted into the lock hole 21 in the first direction, the drive member 222 drives the locking member 221 to move in the second direction, causing the locking edge 2211 to extend into the lock hole 21 and embed into the lock groove 111, completing automatic locking with the lock groove 111. At the same time, the engagement of the mounting groove 12 and the positioning groove 23 is also completed, and the trigger member 31 and the sensor element 32 are precisely aligned.

[0092] This design, with its ingenious internal structure, integrates the lock hole 21, mounting groove 12, sensor element 32, control module 40, alarm module 50, and locking assembly 22 within a cavity formed by the mating of the first panel 24 and the second panel 25, achieving a high degree of product integration and miniaturization. This modular assembly method not only simplifies the production process and reduces manufacturing costs but also makes the overall structure more compact and the appearance more concise and aesthetically pleasing. The locking assembly 22, with its locking element 221 and driving element 222 arranged around the lock hole 21, can form a ring-like locking of the bolt 11, resulting in uniform force distribution, better locking effect, and strong resistance to pull-out.

[0093] Furthermore, in some embodiments, such as Figure 4 and Figure 6 As shown, in order to facilitate unlocking when needed, the card lock 221 is provided with an operation part 2212. The operation part 2212 protrudes from the outside of the female buckle so that the user can operate the card lock 221 to move in the opposite direction of the second direction engagement to drive the card edge 2211 to disengage from the lock groove 111.

[0094] Specifically, the locking element 221 has an integrally formed or fixedly connected operating part 2212. This operating part 2212 is usually a raised lever or push button that passes through a corresponding slot on the female buckle housing and protrudes from the surface of the female buckle. When it is necessary to legally separate the male and female buckles, the user only needs to use his finger to move the operating part 2212, causing the locking element 221 to overcome the driving force of the drive element 222 and slide in the opposite direction to the second direction, thereby causing the locking edge 2211 to disengage from the locking groove 111. After the lock is released, the user can easily pull out the locking tongue 11.

[0095] Furthermore, in some embodiments, such as Figure 6 As shown, in order to achieve a convenient plug-and-lock experience through a simple structure, the drive component 222 includes a first magnetic component, which is fixedly mounted on the locking component 221.

[0096] When the latch 11 is inserted into the lock hole 21 along the first direction and reaches the predetermined position, the first magnetic element fixed on the locking member 221 will generate a magnetic interaction with the magnetic attraction structure (such as an iron element or a permanent magnet) fixed in the male buckle. By designing the arrangement of the N / S poles, this interaction can be an attractive force or a repulsive force, driving the locking member 221 to move automatically along the second direction. For example, if the first magnetic element and the magnetic attraction structure in the male buckle are set to have opposite magnetic poles facing each other, when the latch 11 is inserted into the position and the two come close together, they will attract each other due to the magnetic attraction force, thereby causing the locking edge 2211 to automatically extend into the lock hole 21 and embed into the lock groove 111, completing the automatic locking.

[0097] Furthermore, in some embodiments, such as Figure 2 As shown, in order to further improve the smoothness and guidance of the insertion, the male buckle is provided with a second magnetic element 13, and the female buckle is provided with a third magnetic element 26 that attracts the second magnetic element 13, so that the male buckle and the female buckle are magnetically engaged and the locking tongue 11 is guided to be inserted into the lock hole 21.

[0098] When the male latch approaches the female latch, the attraction between the second magnetic component 13 and the third magnetic component 26 first takes effect, forming a magnetic guidance system. This force guides the male latch to automatically move towards and align with the predetermined position of the female latch, assisting the user in smoothly inserting the latch bolt 11 into the lock hole 21. Even slight positional deviations can be corrected by the magnetic force. The mutual attraction between the male and female latches through the second magnetic component 13 and the third magnetic component 26 provides guidance and pre-tightening force at the beginning of insertion, helping the user to quickly and accurately complete alignment and insertion, further improving the feel and convenience of operation. When unlocking is required, the user only needs to manually push the locking component 221 through the operating part to easily release the lock, achieving one-push opening. This convenient and reliable locking and unlocking method significantly improves the user experience.

[0099] Simultaneously, when the locking tongue 11 is inserted into the lock hole 21 along the first direction, the arrangement of the N / S poles causes the first magnetic element and the second magnetic element 13 to interact, driving the locking element 221 to move along the second direction. This causes the locking edge 2211 to extend into the lock hole 21 and embed into the lock groove 111, engaging with the lock groove 111 to complete automatic locking. This design eliminates the need for complex locking operations such as additional pressing or rotation required in traditional fasteners, achieving a convenient experience of locking with a simple insertion.
