[0065] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0066] The present invention provides an anti-disassembly lock buckle, which can be connected to a watch strap at one end of a watch. When in use, the watch strap at the other end is inserted into the lock buckle and put into a locked state. Once in the locked state, the lock buckle cannot be easily opened and disassembled and can only be opened using a special unlocking tool, thereby ensuring the safety of use.

[0067] Figure 1 A structural schematic diagram of a wristwatch provided by the present invention is shown.

[0068] Reference Figure 1 The wristwatch comprises a dial 10, and two ends of the dial 10 are respectively connected to a short strap 12 and a long strap 11. The long strap 11 is provided with a plurality of adjustment holes 111, and the short strap 12 is provided with a plurality of fixing holes 121.

[0069] The buckle 20 is connected to one end of the short strap 12 , and may be fixedly connected or detachably connected, which is not limited in this embodiment of the present invention.

[0070] For example, in some embodiments, one end of the short strap 12 can be inserted into the buckle 20. Through the fixing hole 121, on the one hand, the connection position between the buckle 20 and the short strap 12 can be adjusted, and on the other hand, the fixing hole 121 at a suitable position can be inserted into the fixing column in the buckle 20 to increase the reliability of the connection.

[0071] Combine the following Figures 2 to 6 The structure of the anti-disassembly lock provided by the present invention is described in detail. Figure 2 is a three-dimensional diagram of the anti-disassembly lock provided by the present invention, Figure 3 This is the exploded structure diagram of the clamshell. Figure 4 This is a top view of the upper cover. Figure 5 is a cross-sectional view of the anti-disassembly lock in the locked state. Figure 6 It is a longitudinal cross-sectional view of the anti-disassembly lock buckle.

[0072] The lock buckle 20 includes a detachably connected base 22 and a flip cover 21. Figure 3 As shown, the flip cover 21 is a double-layer structure, including an upper cover 211 and a lower cover 212.

[0073] The lower cover 212 is provided with a sensing mechanism, which is used to cooperate with the signal generating mechanism in the watch band to trigger the signal generating mechanism to send a status signal to the host, so that the host determines the status of the flip cover (21) according to the status signal.

[0074] In a non-limiting embodiment, the signal generating mechanism may be disposed in the long strap 11 , and the host may be disposed in the dial 10 .

[0075] Reference Figure 3 and Figure 5 For example, magnets and Hall switches can be used to achieve the above functions, such as Figure 3 As shown in FIG. 2 , a magnet 41 is provided as the induction mechanism on the outer surface of the lower cover 212. Figure 5 As shown, the Hall switch 42 is set at a suitable position in the long strap 11.

[0076] When the watch is worn on the corresponding wrist or ankle, and the long strap 11 is inserted into the lock 20, when the flip cover 21 is pressed into the base, the distance between the magnet 41 and the Hall switch 42 changes, that is, from far to near. Correspondingly, the magnetic field intensity sensed by the Hall switch 42 changes from small to large, and accordingly, the output voltage of the Hall switch 42 changes accordingly, such as Figure 7 As shown, the host can determine whether the lock has entered the locked state based on the change.

[0077] Similarly, when the lock 20 is opened, the flip cover 21 flips over, and the distance between the magnet 41 and the Hall switch 42 changes from close to far. Accordingly, the magnetic field strength sensed by the Hall switch 42 changes from large to small, and accordingly, the output voltage of the Hall switch 42 changes accordingly, such as Figure 7 As shown, the host can determine whether the lock is opened according to the change.

[0078] Furthermore, the wristwatch of the embodiment of the present invention also has the ability to prevent magnetic interference. The magnetic field reverses the signal sent by the Hall switch 42, and the host can determine whether there is magnetic interference. Figure 7 This is explained in detail.

[0079] like Figure 7 , which is a schematic diagram of a voltage signal generated by the magnet in the anti-disassembly lock provided by the present invention and the Hall switch in the strap.

[0080] The meaning of each parameter is as follows:

[0081] VDD: supply voltage; V OH Indicates high level, V OL Indicates low level;

[0082] Off-State: Indicates the Hall switch is off;

[0083] On_state: indicates the Hall switch is on;

[0084] Turn on: indicates the flip cover is open;

[0085] Turn Off: Indicates the flip cover is closed;

[0086] OutN: N-pole output; OutS: S-pole output;

[0087] B OPN : N-pole magnetic field working point; B OPS : S pole magnetic field working point;

[0088] B RPN : N-pole magnetic field release point; B RPS : S pole magnetic field release point;

[0089] B HY : Hysteresis range (equivalent to a buffer zone between opening and closing).

[0090] Also refer to Figure 3 and Figure 5 , assuming that the S-pole magnetic induction intensity applied by the Hall switch 42 exceeds the working point B OPS When the Hall switch chip pin 1 outputs a low level and maintains a low level; the applied N-pole magnetic induction intensity exceeds the working point B OPN When the Hall switch chip 3 pin outputs a low level, and maintains a low level until the magnetic induction intensity of the S pole or N pole is lower than the release point B. RPS or B RPN When the Hall switch chip pins 1 and 3 output high level, there are three situations for the levels of the Hall switch pins 1 and 3. Assuming the high level is 1 and the low level is 0, the three situations can be expressed as: (0,1), (1,0), (1,1). Among them:

[0091] (0,1) indicates that the N pole is close to the Hall switch and reaches the N-level magnetic field operating point Bopn. OutN outputs a low level and OutS outputs a high level. The N level is in the on state and the S level is in the off state.

[0092] (1,0) indicates that the S pole is close to the Hall switch and reaches the S-level magnetic field operating point. OutN outputs a high level and OutS outputs a low level.

[0093] (1,1) indicates that no magnet approaches, or that the magnet approaches but does not reach the magnetic field operating point Bopn. That is, when the magnet moves away and the N-pole magnetic field weakens to the N-pole magnetic field release point Brpn or the S-pole magnetic field weakens to the S-pole magnetic field release point Brps, the Hall switch is closed and both OutN and OutN output high level.

[0094] In some embodiments, the N pole of the magnet 41 is set to face the Hall switch. Then, after the flip cover 21 is pressed into the base 22, the Hall switch 42 senses that the N pole strength of the magnet 41 is higher than Bopn, and the pin 1 of the Hall switch chip outputs a low level and the pin 3 outputs a high level. This is the default locked state.

[0095] When there is other magnetic field interference, such as interference from an S-pole magnet, and the intensity of the interfering magnetic field is greater than the magnetic field intensity of the current magnet 41, causing the N pole of the magnet 41 to reverse to the S pole, and is greater than the intensity of the Bops point, pin 3 of the Hall switch chip outputs a low level and pin 1 outputs a high level. Based on this, the host can determine that the watch is currently subject to magnetic interference.

[0096] In some embodiments, the host can determine the state of the flip cover 21 according to the state signal. For example, when the received voltage signal is less than a set value, it is determined that the flip cover 21 is open. At this time, the host can issue an alarm.

[0097] In the example of the present invention, the host may have one or more ways to send an alarm, such as:

[0098] In some embodiments, an alarm module may be provided inside the dial, such as a buzzer, or a voice alarm.

[0099] In other embodiments, the alarm may be issued by sending an alarm signal to a monitoring center or a corresponding terminal device.

[0100] Of course, there may be other alarm methods. In specific use, multiple alarm methods may be used simultaneously to ensure all-round monitoring of the wearer.

[0101] Continue to refer to Figure 2 The base 22 includes a bottom plate 221 and two side walls 222; one side of the flip cover 21 is connected to one side of the bottom plate 221 by rotating and opening.

[0102] For example, in a non-limiting embodiment, corresponding first screw holes 201 are provided on the two side walls 222 of the base 22 , and the base 22 and the flip cover 21 may be connected via a first screw shaft 301 passing through the first screw hole 201 .

[0103] As mentioned above, the anti-disassembly buckle 20 of the embodiment of the present invention and one of the watch straps (such as the short watch strap 12) can be fixedly connected or detachably connected.

[0104] like Figure 2 and Figure 3 As shown, in a non-limiting embodiment, a corresponding second screw hole 202 is provided on each side wall 222 of the base 22 to pass the second screw shaft 302 to fix the strap.

[0105] The first screw hole 201 and the second screw hole 202 are distributed vertically.

[0106] The strap comprises: a short strap 12 and a long strap 11; in order to conveniently fix the short strap 12 and the long strap 11, and to conveniently adjust according to the fineness of the wearer's wrist circumference, such as Figure 1 As shown, a plurality of fixing holes 121 are provided on the short strap 12; a plurality of adjusting holes 111 are provided on the long strap 11; the sizes of the fixing holes 121 and the adjusting holes 111 may be the same or different, which is not limited in this embodiment of the present invention.

[0107] Correspondingly, a fixing column 23 adapted to the fixing hole 121 is provided on the bottom plate 221 of the base 22 for fixing the short strap 12. When the lock buckle 20 is installed on the short strap 12, the fixing column 23 passes through a fixing hole 121 on the short strap 12.

[0108] Correspondingly, a fastening column 2121 adapted to the adjustment hole 111 is provided on the outer surface of the lower cover 212 for fixing the long strap 11. When the lock buckle 20 is in a locked state, the fastening column 2121 passes through an adjustment hole 111 on the long strap 11.

[0109] Through the above-mentioned fixing column 23 and the fastening column 2121, the connection between the lock buckle 20 and the watch strap can be easily achieved, and the position of the lock buckle 20 can be easily adjusted to better adapt to the wrist circumference of different wearers.

[0110] Furthermore, the top of the fixing column 23 has a boss 231, and the top of the fastening column 2121 has a groove 2122 adapted to the boss 231. Accordingly, when the lock buckle 20 is in the locked state, the boss 231 is inserted into the groove 2122, which can enhance the locking strength.

[0111] like Figure 3 As shown, the upper cover 211 and the lower cover 212 can be fixed by screws 210 .

[0112] Continue to refer to Figures 2 to 6 The two side walls 222 of the base 22 are provided with card slots 24 .

[0113] Two slide grooves 30 are arranged on the inner surface of the upper cover 211, and a slider 31 and a slide spring 32 are arranged in the slide groove 30; one end of the slider 31 has a sliding tongue 311 adapted to the slot 24 and protruding from the side of the upper cover 211, the other end of the slider 31 abuts against the slide spring 32, and the other end of the slide spring 32 abuts against one end of the slide groove 30.

[0114] When the watch is worn, after the flip cover 21 is turned over and pressed into the base 22, the slider 31 is bounced into the slide groove 30 under the action of the slider spring 32, so that the flip cover 21 is fixed and cannot rotate.

[0115] Furthermore, a lock hole 33 is provided on the upper cover 211 for inserting the turn buckle 34 to put the lock buckle 20 into a locked state.

[0116] Furthermore, a through hole 312 is provided on the slider 31, and a rotating post 341 is provided on the rotating buckle 34. After the flip cover 21 is turned over and pressed into the base 22, the rotating post 341 is inserted into the through hole 312, thereby enhancing the firmness of the locking state of the locking buckle.

[0117] In some embodiments, an ejector spring 52 is further provided on the inner surface of the upper cover 211 , and an ejector 51 is sleeved on the upper end of the ejector spring 52 .

[0118] When unlocking is required, a special unlocking tool can be inserted into the turn buckle 34 and rotated counterclockwise, and the rotating column 341 drives the slider 31 to move, so that the slider 31 exits the slide groove 30, and the ejector pin 51 is pushed upward out of the turn buckle 34 under the action of the ejector spring 52. In this way, the slider 31 can be prevented from sliding into the slide groove 30 again under the action of the elastic force after losing the action force.

[0119] In some embodiments, the two side walls 222 of the base 22 and the flip cover 21 may also be provided with matching locking reinforcement structures. Figure 2 As shown, a pit 61 is provided on the base 22, and a protrusion 62 of corresponding position and size is provided on the upper cover 211 of the flip cover 21, so that after the flip cover 21 is flipped over and pressed into the base 22, the protrusion 62 is embedded in the pit 61, thereby enhancing the locking strength of the flip cover 21 and the base 22.

[0120] Accordingly, an embodiment of the present invention further provides a wristwatch, such as Figure 1 As shown, the watch includes: a dial 10, a short strap 12 and a long strap 11 respectively connected to the two ends of the dial 10, and a buckle 20; the buckle 20 can be detachably connected to the short strap 12, or can be fixedly connected to the short strap 12, which is not limited in this embodiment of the present invention.

[0121] Also refer to Figure 2 As shown in the schematic diagram of the lock structure, a signal generating mechanism may be provided in the long strap 11 , and a host may be provided in the dial 10 .

[0122] The signal generating mechanism can cooperate with the sensing mechanism provided on the lower cover 212 of the lock buckle 20 to generate and send a status signal to the host. Accordingly, the host can determine the status of the flip cover 21 of the lock buckle 20 according to the status signal, and issue an alarm after determining that the flip cover 21 is open.

[0123] The anti-disassembly lock and watch provided by the present invention are provided with a double-layer flip cover structure, and a sensing mechanism is provided on the lower cover to cooperate with a signal generating mechanism in the watch strap, triggering the signal generating mechanism to send a status signal to the host, so that the host can determine the status of the flip cover according to the status signal, thereby playing a real-time monitoring of the status of the lock, and effectively ensuring the safety of the lock during use.
