Description

Technical Field

[0001] The utility model relates to a lock, in particular to an anti-theft tag lock. Background Art

[0002] The wire tag lock is a kind of lock used in various fields, especially a tag lock used for sealing containers. The existing wire rope tag lock includes a lock body with a wire rope, and a monitoring circuit for monitoring the locking status is arranged inside the lock body; when the wire rope is inserted into the lock hole; the wire rope is used as a locking component to complete the locking of the mechanical mechanism on the one hand, and the wire rope itself is a conductor, as a part of the monitoring circuit path, to turn on the monitoring circuit. When the monitoring circuit is turned on, the tag lock reports the locking status to the background. While the goods are in transit, if someone cuts the wire rope, the monitoring circuit will change from a circuit to an open circuit, and the tag lock will report the unlocking status to the background. The monitoring circuit can be used to know the time when the wire rope tag lock is opened to facilitate responsibility tracing. However, it was found during use that when a thief such as Figure 1 After short-circuiting the wire rope as shown, Figure 2 As shown in the figure, by cutting the steel wire rope between the two short-circuit points, the monitoring circuit path can be maintained while the steel wire is cut, so as to avoid the monitoring of the monitoring circuit and make it impossible to know when the steel wire rope tag lock is opened. How to prevent the above situation from happening is an urgent problem to be solved in the industry. Utility Model Content

[0051] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0052] In view of the above-mentioned defects of the prior art tag lock, this embodiment provides an anti-theft tag lock, such as Figure 3 As shown, the lock body 1 is provided with a circuit, and the wire 6 of the circuit is arranged in at least a part of the locking section of the steel wire rope 2. When the wire 6 is disconnected, it is determined that the steel wire rope tag lock is opened. In this embodiment, the circuit includes an MCU and a power supply, and the power supply is used to power the circuit and the MCU, wherein the MCU and the power supply can be installed in a hard shell and arranged on the outer shell of the lock body 1, or can be arranged inside the lock body 1. The MCU has a voltage or current identification pin, and the wire 6 is electrically connected to the voltage or current identification pin. When the wire 6 is disconnected, the signal identified by the identification pin will change, so that the signal of the physical disconnection of the wire 6 can be converted into an electrical signal to be recognized by the MCU. In this embodiment, the wire 6 of the circuit is arranged in the locking section of the steel wire rope 2. When the thief cuts the steel wire rope 2, the wire 6 of the circuit will also be cut, so that the steel wire rope tag lock can identify the information that the steel wire rope 2 is cut.

[0053] It should be noted that the wire locking section referred to in the present invention is the wire rope section between the fixed end and the locking hole after the wire rope 2 is inserted into the locking hole.

[0054] In this embodiment, the wire 6 is insulated from the wire 2 at the locking section of the wire 2, so that the circuit of the wire 6 is independent of the detection circuit of the wire 2. The insulation method may include using enameled wire for the wire 6 or providing an insulating medium between the wire 2 and the wire 6.

[0055] According to an embodiment of the utility model, the wire 6 of the circuit is arranged in more than 90% of the area of ​​the locked section of the steel wire rope 2, and the wire 6 is arranged to cover the entire locked section of the steel wire rope 2 as much as possible, so that the thief cannot cut the locked section of the steel wire rope 2 after the locked state is formed without destroying the wire 6. The wire 6 is preferably arranged in the entire area of ​​the locked section of the steel wire.

[0056] According to an embodiment of the utility model, a plurality of wires 6 are provided on the locking section of the steel wire rope 2, and a plurality of independent circuits are formed at the same time. The plurality of wires 6 are arranged on the locking section of the steel wire rope 2, and when the wire 6 of any of the circuits is disconnected, it is determined that the steel wire rope tag lock is opened. Adding a plurality of circuits with the same function can effectively improve the overall stability on the one hand, and when one of the circuits fails, the other circuits can still work normally to prevent theft, and on the other hand, it increases the difficulty for thieves to circumvent the circuit and cut the steel wire rope 2.

[0057] According to one embodiment of the utility model, the circuit is independent of the original monitoring circuit of the wire rope tag lock, and the circuit is a normally closed circuit. An MCU is connected to the circuit, and when the MCU recognizes that the voltage or current signal of the circuit changes, it determines that the wire rope tag lock is opened. The wire 6 is electrically connected to the identification pin of the MCU, and when the wire 6 is disconnected, the voltage or current signal on the identification pin of the MCU will change. The change may include: an increase, decrease or disappearance of the voltage or current, etc.

[0058] Since the circuit in this embodiment includes an MCU, the MCU has not only an identification function but also a program writing function, so a plurality of implementation methods are provided for the judgment mechanism of whether the tag lock is opened, as shown below:

[0059] Mode 1: When the MCU identifies that the circuit is broken, it determines that the wire rope tag lock is opened.

[0060] Method 2: When the MCU recognizes that the circuit is suddenly broken, it determines that the wire rope tag lock is opened. This mainly refers to a non-progressive linear break, because when the power supply is low, the current and voltage in the circuit are slowly reduced and eventually reach a state of breaking. Such judgment logic can avoid misjudgment and false alarm caused by long-term non-use of the battery or low power in some abnormal battery states.

[0061] Method 3: When the MCU recognizes a sudden change in the voltage or current signal of the circuit, it determines that the wire rope tag lock is opened. Such judgment logic can avoid misjudgment and false alarm caused by long-term battery disuse or battery power loss in some abnormal state.

[0062] Mode 4: When the MCU recognizes that the current signal of the circuit suddenly becomes 0, it determines that the wire rope tag lock is opened. Such judgment logic can avoid misjudgment and false alarm caused by long-term battery disuse or battery power loss in some abnormal state.

[0063] According to an embodiment of the utility model, when the MCU determines that the wire rope tag lock is opened, the MCU records the opening time. In this embodiment, when the wire rope tag lock is determined to be opened, the wire rope tag lock records the opening time. When a theft occurs, the investigator can trace it back by checking the opening time of the wire rope tag lock.

[0064] According to one embodiment of the utility model, the MCU is connected to a transmission module, and when the MCU determines that the wire rope tag lock is opened, the MCU sends a signal that the wire rope tag lock is opened through the transmission module. In this embodiment, at the first time when the wire 6 is disconnected, the MCU of the wire rope tag lock sends the opening time to the background through the transmission module. The timeliness of anti-theft monitoring can be increased, and the storage method of anti-theft data can be increased to facilitate real-time monitoring or subsequent tracing. When it is determined that the wire rope tag lock is opened, the transmission module (or data transmission module) of the wire rope tag lock sends an alarm signal. In this embodiment, the alarm signal can be transmitted to other devices wirelessly to realize an alarm, such as being transmitted to a siren through the network for a large-scale reminder, and being transmitted to the corresponding client through the background for targeted notification. By sending an alarm signal, on the one hand, the carrier can be prompted so that it can deal with it in time, and on the other hand, other personnel related to the goods can be notified at the first time so that they know the situation of the goods in transit.

[0065] According to an embodiment of the utility model, the wire rope tag lock has a GSM module. When the MCU determines that the wire rope tag lock is opened, the MCU realizes external wireless communication through the GSM module and sends the information that the wire rope tag lock is opened to other terminal devices.

[0066] According to an embodiment of the utility model, the circuit is independent of the original monitoring circuit of the wire rope tag lock, and the circuit is a normally closed circuit. The circuit can share the power supply and MCU with the original monitoring circuit of the wire rope 2, such as Figure 5 As shown, the resistor R2 represents the wire 6 arranged on the locking section of the wire rope 2, the resistor R1 represents the wire rope 2, and the power supply is used to power the monitoring circuit and the MCU. When the wire rope 2 is inserted into the lock hole, the switch in the figure is closed and the original monitoring circuit of the wire rope tag lock is turned on. In this embodiment, when the anti-theft tag lock of the utility model is locked, the wire 6 and the wire rope 2 are connected to their respective paths. When any one of the two paths is broken, it can be determined that the tag lock is opened, which can prevent thieves from creating the illusion that it is not opened by short-circuiting the wire rope 2.

[0067] An anti-theft tag lock, in which a conductor 6 is arranged in at least a part of the locking section of a steel wire rope 2, and the conductor 6 is connected in series to the monitoring circuit of the steel wire rope tag lock. When the steel wire rope 2 of the steel wire rope tag lock is inserted into the lock hole, the monitoring circuit is turned on, and when the conductor 6 is disconnected, it is determined that the steel wire rope tag lock is opened. In this embodiment, the conductor 6 is connected in series with the steel wire rope 2 of the steel wire rope tag lock, and the circuit is turned on when the steel wire rope tag lock is inserted into the lock hole. The anti-theft tag lock of this embodiment does not add an additional circuit. By connecting a conductor 6 in series to its original monitoring circuit and arranging the conductor 6 in the locking section of the steel wire rope 2, the anti-theft function can be achieved.

[0068] In this embodiment, one end of the wire 6 arranged on the locking section of the wire rope 2 is electrically connected to the power supply end, and the other end is connected to the fixed end of the wire rope 2, and the connection positions of the two ends of the wire are located inside the lock body 1. For example, the wire 6 can be connected to the fixed end and the power supply end of the wire rope 2 by welding (for example, it can be brazing). The power supply end described in this embodiment is electrically connected to the positive or negative pole of the power supply. That is, the newly added wire 6 is connected in series in the existing wire rope monitoring circuit of the wire rope tag lock, specifically between the fixed end of the wire rope tag lock and the power supply end. Its circuit structure can be as follows Figure 6 As shown, the resistor R2 represents the wire 6 arranged on the locking section of the wire rope 2, and the resistor R1 represents the wire rope 2. When the wire 6 or the wire rope 2 is disconnected at any point, the monitoring circuit will be broken. When the circuit is broken, the MCU can recognize the corresponding signal state change, thereby determining that the wire rope tag lock is opened.

[0069] In the embodiment where the wire 6 is connected in series with the steel wire 2, the two ends of the wire 6 are respectively connected to the fixed end and the power supply end of the steel wire 2 by welding (for example, brazing). The spatial layout of the wire 6, the determination mechanism of whether the steel wire tag lock is opened, and the functions that can be realized by the MCU described in the above embodiment of setting up the circuit separately are also applicable to the embodiment where the wire 6 is connected in series with the steel wire 2.

[0070] According to an embodiment of the utility model, this embodiment provides an anti-theft tag lock, such as Figure 3-4 As shown, the anti-theft tag lock includes:

[0071] A lock body 1, wherein the lock body 1 is provided with a lock hole;

[0072] A steel wire rope 2, one end of which is connected to the lock body 1, and the other end of which is used to be inserted into a lock hole on the lock body 1 to achieve locking;

[0073] A circuit, wherein the wire 6 of the circuit is arranged in at least a part of the locking section of the wire rope 2, and when the wire 6 is disconnected, it is determined that the wire rope tag lock is opened. The circuit is based on the circuit in the tag lock of the utility model. The connection positions of both ends of the wire 6 are located inside the lock body 1.

[0074] According to an embodiment of the utility model, the circuit is independent of the original monitoring circuit of the wire rope tag lock, and the circuit is a normally closed circuit. The circuit can share the power supply and MCU with the original monitoring circuit of the wire rope 2, such as Figure 5 As shown, the resistor R1 represents the steel wire rope 2, the resistor R2 represents the wire 6 arranged in the locking section of the steel wire rope 2, and the power supply is used to power the original monitoring circuit of the steel wire rope 2 and the MCU, wherein the fixed end of the steel wire rope 2 is connected to the VID2 pin of the MCU, and the free end of the steel wire rope 2 is connected to the negative pole of the power supply by inserting it into the lock hole, thereby turning on the monitoring circuit, one end of the wire 6 is connected to the positive pole of the power supply (in some scenarios, it may not be limited to the positive pole of the power supply, as long as the wire 6 can be connected to the circuit of the MCU), and the other end is connected to the VID1 pin of the MCU (in some scenarios, it may not be limited to the voltage identification pin, as long as the wire 6 can be connected to the circuit of the MCU). In this embodiment, when the anti-theft tag lock of the utility model is locked, the wire 6 and the steel wire rope 2 are both connected to their respective paths. When any of the two paths is disconnected, it can be determined that the tag lock is opened, which can prevent thieves from creating the illusion that it is not opened by short-circuiting the steel wire rope 2.

[0075] In this embodiment, the MCU is also connected to a data transmission module. Through the data transmission module, when the MCU determines that the wire rope tag lock is opened, it can include transmitting relevant signals to the outside, and the relevant signals include time signals, alarm signals, etc.

[0076] In this embodiment, the power supply and MCU of the circuit are both arranged inside the lock body 1. A PCB board 5 is arranged inside the lock body 1, and the MCU is arranged on the PCB board 5. Both ends of the wire 6 are connected to the circuit by connecting to the PCB board 5.

[0077] In this embodiment, the conductive wire 6 is arranged in the entire area of ​​the steel wire locking section.

[0078] In this embodiment, a covering layer is formed on the locking section of the steel wire rope 2, and the covering layer covers the steel wire rope 2. The relationship between the covering layer and the conductor 6 can include multiple situations, such as the conductor 6 is outside the covering layer, in which case the covering layer is equivalent to an insulating layer, isolating the conductor 6 from the steel wire rope 2, in which case the conductor 6 does not necessarily have to be an enameled wire; if the conductor 6 is arranged in the covering layer, close to the steel wire rope 2, and insulated from the steel wire rope 2, in which case the conductor 6 can be an enameled wire; if the conductor 6 is embedded in the covering layer, in this case, the covering layer isolates the contact between the conductor 6 and the steel wire rope 2, and provides fixation for the conductor 6.

[0079] According to an embodiment of the utility model, the wire 6 is embedded in the covering layer, and the covering layer is provided so that the wire 6 and the steel wire 2 of the wire rope tag lock form a physically integrated structure, making it difficult for thieves to separate the wire 6 and the steel wire 2 from each other and short-circuit them separately. In this embodiment, the covering layer is made of insulating material. In addition to combining the functions of the steel wire 2 and the wire 6, it is also used to wrap the steel wire 2 and the wire 6 therein, making it impossible to short-circuit the steel wire 2 or the wire 6 in a non-destructive manner, further improving the anti-theft performance of the wire rope tag lock of the utility model. The covering layer in this embodiment is formed by coating with insulating paint, and can also be formed by a rubber tube or a plastic tube sleeved on the locking section of the steel wire 2.

[0080] Furthermore, in this embodiment, the covering layer is opaque, and when the covering layer covers the wire 6 arranged on the locking section of the wire rope 2, the covering layer also covers the locking section of the wire rope 2, so that the wire rope 2 forms a whole visually. The thief cannot distinguish the specific position of the wire 6, further improving the anti-theft performance of the wire rope tag lock of the utility model.

[0081] According to one embodiment of the utility model, Figure 4 As shown, a sleeve 3 is sleeved on the locking section of the steel wire rope 2, and the wire 6 arranged on the locking section of the steel wire rope 2 is embedded in the tube body of the sleeve 3. By embedding the wire 6 into the tube body of the sleeve 3, the wire 6 and the tube body form a physically identical structure. When a thief attempts to circumvent the monitoring of the monitoring circuit by short-circuiting the steel wire rope 2, it is necessary to expose the steel wire rope 2 covered by the sleeve 3, which inevitably requires destroying the sleeve 3 of the locking section of the steel wire rope 2. When the thief breaks the outer sleeve 3, the wire 6 inside it will also be destroyed, so that the steel wire rope tag lock of the utility model can recognize the signal of being opened, and then record the opening time locally or send the opening time to the background or send an alarm signal, so as to realize a local alarm to prompt the carrier or a remote alarm to notify other people related to the goods.

[0082] According to an embodiment of the utility model, a double-layer sleeve 3 is sleeved on the locking section of the steel wire rope 2, and the wire 6 arranged on the locking section of the steel wire rope 2 is located between the inner and outer layers of the double-layer sleeve 3. By designing the sleeve 3 as a double-layer, it is convenient to manufacture a structure in which the wire 6 and the sleeve 3 are integrated. During manufacturing, the wire 6 is first arranged on the base material of the single-layer sleeve 3 to form a structure in which the wire 6 is arranged outside the sleeve 3, and then the base material of another outer sleeve 3 is arranged on the structure to form a double-layer sleeve 3 with the wire 6 embedded in the middle layer. Or the double-layer sleeve 3 can also be formed directly by directly nesting two sleeves 3, one large and one small. The sleeve 3 can protect the wire 6 on the one hand and prevent it from breaking too easily; on the other hand, it can prevent thieves from knowing the specific position of the wire in the sleeve 3. The setting of the wire and the double-layer sleeve is convenient for manufacturing, and has a more stable and reliable structure, avoiding problems such as short circuits that may be caused by the wire and the steel wire being too close, and greatly improving the stability and durability of the anti-theft function of the tag lock.

[0083] According to one embodiment of the utility model, the conductor 6 of the locked section of the wire rope 2 is reciprocated multiple times between the two ends of the locked section of the wire rope 2 in the casing 3. By reciprocating multiple times between the two ends, the conductor 6 can wrap the locked section of the wire rope 2 as much as possible, thereby increasing the difficulty of avoiding the conductor 6 from damaging the wire rope 2.

[0084] According to an embodiment of the utility model, in order to further improve the difficulty of circumventing the wire 6, the wire 6 in this embodiment is reciprocated and wound along the casing 3 for multiple times to form a mesh, and each intersection is insulated from each other. In this way, the wire 6 forms a mesh to wrap the steel wire rope 2 therein, which greatly improves the difficulty of circumventing the wire 6 when the casing 3 is damaged. In order to prevent the wire 6 from being disconnected due to the contact of the intersection in the casing 3, the enameled wire can be used as the raw material of the wire 6 in this embodiment to ensure that each intersection is insulated from each other.

[0085] According to one embodiment of the utility model, the wire 6 is arranged in at least a part of the locking section of the steel wire rope 2, and the wire 6 is connected in series to the monitoring circuit of the steel wire rope tag lock. When the steel wire rope 2 is inserted into the lock hole, the monitoring circuit is turned on, and when the wire 6 is disconnected, it is determined that the steel wire rope tag lock is opened. In this embodiment, one end of the wire 6 arranged in the locking section of the steel wire rope 2 is connected to the power supply end, and the other end is connected to the fixed end of the steel wire rope 2, and the connection positions of the two ends of the wire 6 are located inside the lock body 1, and the wire 6 is connected to the fixed end and the power supply end of the steel wire rope 2 by welding. Its circuit structure is as follows Figure 6As shown, the resistor R1 represents the steel wire rope 2, and the resistor R2 represents the wire 6 arranged on the locking section of the steel wire rope 2. In this embodiment, the wire 6 is located between the steel wire rope 2 and the VID pin of the MCU (in some scenarios, it may not be limited to being connected to the voltage identification pin, as long as the wire 6 can be connected to the monitoring circuit). When the steel wire rope 2 is inserted into the lock hole, the steel wire rope 2 can establish an electrical connection with the negative electrode of the power supply (in some scenarios, it may not be limited to being connected to the negative or positive electrode of the power supply, as long as the wire 6 can be connected to the monitoring circuit), that is, Figure 6 The switch in the wire rope tag lock is closed and the existing monitoring circuit of the wire rope tag lock is turned on. When the wire 6 or the wire rope 2 is disconnected at any point, the monitoring circuit will be broken. When the circuit is broken, the MCU can identify the corresponding signal state change, thereby determining that the wire rope tag lock is opened. In this embodiment, the MCU is also connected to a data transmission module. Through the data transmission module, when the MCU determines that the wire rope tag lock is opened, relevant signals can be transmitted to the outside, and the relevant signals include time signals, alarm signals, etc.

[0086] like Figure 6 The power supply and the MCU are both arranged inside the lock body 1, and the two ends of the wire 6 are electrically connected to the circuit. Specifically, a PCB board 5 is arranged inside the lock body 1, and the MCU is arranged on the PCB board 5. One end of the wire 6 is connected to the circuit by connecting to the PCB board 5, and the other end is connected to the fixed end of the wire rope 2 by welding.
