[0001] This utility model relates to the field of anti-theft technology, and in particular to an anti-theft tag. Background Technology

[0002] In existing technology, anti-theft tags are typically attached to goods for sale in shopping malls and supermarkets. These tags are usually attached to the goods with steel wire ropes. When someone takes a product with an anti-theft tag attached, an alarm system at the entrance can detect the wireless signal emitted by the tag and sound an alarm to alert staff. However, if the steel wire rope is forcibly cut without proper unlocking, traditional anti-theft tags cannot immediately alert staff, leaving the goods still at risk of being stolen.

[0003] Therefore, the above problems urgently need to be solved. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-theft tag to solve the problem that when the steel wire rope of the anti-theft tag is forcibly cut without normal unlocking, the traditional anti-theft tag cannot alert staff in time, thus leaving the goods at risk of being stolen.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Anti-theft tags, including:

[0007] The outer casing contains a circuit board and an alarm, with the alarm electrically connected to the circuit board.

[0008] A connecting rope has one end inserted into the housing and the other end located outside the housing. A first wire and a second wire are arranged inside the connecting rope along its length. One end of the first wire and the second wire extends through the end of the connecting rope inside the housing and is electrically connected to the circuit board. The other ends of the first wire and the second wire are electrically connected inside the connecting rope and are adjacent to the end of the connecting rope outside the housing.

[0009] A locking structure is provided, wherein one end of the connecting rope located outside the housing can be connected to the locking structure to form a closed loop, the locking structure being configured to lock and keep the loop closed.

[0050] Example 1

[0051] Please see Figures 1 to 6 This embodiment provides an anti-theft tag, which includes a housing 11, a circuit board 12 and an alarm 13 disposed inside the housing 11, and the alarm 13 is electrically connected to the circuit board 12.

[0052] In addition to the outer casing 11, circuit board 12, and alarm 13, the anti-theft tag also includes a connecting rope 14. One end of the connecting rope 14 extends into the outer casing 11, and the other end is located outside the outer casing 11. A first wire 141 and a second wire 142 are arranged inside the connecting rope 14 along its length. One end of the first wire 141 and the second wire 142 extends through the end of the connecting rope 14 located inside the outer casing 11 and is electrically connected to the circuit board 12. The other ends of the first wire 141 and the second wire 142 are electrically connected inside the connecting rope 14 and are adjacent to the end of the connecting rope 14 located outside the outer casing 11. That is, the other ends of the first wire 141 and the second wire 142 are inside the connecting rope 14 and are adjacent to the end of the connecting rope 14 located outside the outer casing 11. The other ends of the first wire 141 and the second wire 142 are connected in series so that the other ends of the first wire 141 and the second wire 142 are electrically connected.

[0053] In addition, the anti-theft tag also includes a locking structure. One end of the connecting rope 14 located outside the housing 11 can be connected to the locking structure to form a closed loop 143. Thus, the connecting rope 14 can be bent to form the loop 143, and the anti-theft tag can be hung on the product through the loop 143. The locking structure is configured to lock and keep the loop 143 closed. In other words, the locking structure is configured to lock the loop 143 and keep it closed, so that under normal circumstances, the anti-theft tag can only be removed from the product by unlocking.

[0054] Therefore, in this embodiment, the first wire 141 and the second wire 142 disposed inside the connecting rope 14 can form a closed loop with the circuit board 12. Moreover, since the connection point of the first wire 141 and the second wire 142 is adjacent to the end of the connecting rope 14 located outside the outer casing 11, the first wire 141 and the second wire 142 can be distributed throughout various parts of the hanging ring 143. When the anti-theft tag is forcibly cut off the connecting rope 14 without normal unlocking, the first wire 141 and the second wire 142 are cut off, thereby causing the closed loop to break. The circuit board 12 can then control the alarm 13 to emit an alarm signal to alert the staff, thereby preventing the theft of goods.

[0055] Specifically, based on the above description, a receiving cavity 113 is formed inside the outer casing 11. The circuit board 12 and the alarm 13 are disposed within the receiving cavity 113. The outer casing 11 is provided with a through hole 114, through which the connecting rope 14 extends into the outer casing 11, and the first wire 141 and the second wire 142 are inserted into the receiving cavity 113. Workers can first bend the connecting rope 14 and pass it through the part of the product used to hang the anti-theft tag, thereby hanging the anti-theft tag on the product. After a consumer purchases the product, the worker can unlock the locking mechanism to release the lock on the hanging ring 143, and then remove the anti-theft tag from the product.

[0056] For example, in this embodiment, the locking structure includes a pin 5 and a locking element 6. The pin 5 is disposed at one end of the connecting rope 14 located outside the housing 11. That is, in this embodiment, the end of the first wire 141 away from the pin 5 extends out of the connecting rope 14 via the end of the connecting rope 14 away from the pin 5, and the end of the second wire 142 away from the pin 5 extends out of the connecting rope 14 via the end of the connecting rope 14 away from the pin 5. The end of the first wire 141 near the pin 5 and the end of the second wire 142 near the pin 5 are electrically connected inside the connecting rope 14, and the connection point of the first wire 141 and the second wire 142 is disposed near the pin 5. Specifically, the connection point of the first wire 141 and the second wire 142 is disposed adjacent to the pin 5. The end of the connecting rope 14 away from the pin 5 is inserted into the housing 11 through the through hole 114, and the end of the first wire 141 extending out of the connecting rope 14 and the end of the second wire 142 extending out of the connecting rope 14 are both electrically connected to the circuit board 12. The locking element 6 is provided with a socket 7 and a lock hole 8. The pin 5 can pass through the socket 7 and be inserted into and locked in the lock hole 8.

[0057] Therefore, in this embodiment, the outer shell 11, circuit board 12, alarm 13 and connecting rope 14 together constitute the alarm device 1. The alarm device 1 and the locking member 6 are two independent components. The alarm device 1 can be connected to the locking member 6 through the connecting rope 14. Since the two ends of the connecting rope 14 are respectively connected to the outer shell 11 and the locking member 6, and the connecting rope 14 passes through the insertion hole 7 on the locking member 6, the connecting rope 14 can be bent to form a hanging ring 143. The anti-theft tag can be hung on the goods through the hanging ring 143.

[0058] Specifically, staff can first pass the connecting rope 14 through the part of the product used to hang the anti-theft tag and the insertion hole 7 on the locking member 6, and then insert and lock the pin 5 of the connecting rope 14 into the lock hole 8, thereby forming a hanging ring 143 between the insertion hole 7 and the lock hole 8 on the locking member 6. The hanging ring 143 is hung on the product to hang the anti-theft tag on the product. When the consumer purchases the product, the staff can unlock the pin 5 by controlling the locking member 6 to remove the anti-theft tag from the product.

[0059] It is understood that the locking component 6 can be equipped with a wireless unlocking structure, a password unlocking structure, or a magnetic unlocking structure, thereby realizing the locking or unlocking of the pin 5. It is worth noting that since the specific construction and working principle of all the unlocking structures mentioned above are existing technologies, this embodiment will not elaborate on them.

[0060] It is also worth noting that in this embodiment, the connecting rope 14 is a single rope. That is, in this embodiment, the first conductor 141 and the second conductor 142 are arranged in the same rope. Of course, in other optional embodiments, the connecting rope 14 can also be composed of two ropes, with the first conductor 141 and the second conductor 142 respectively arranged in the two ropes. One end of the two ropes extends into the outer shell 11, and the other end of the two ropes is located outside the outer shell 11. The other ends of the two ropes are connected in series so that the first conductor 141 and the second conductor 142 respectively arranged in the two ropes can be connected in series and electrically connected. Moreover, based on the above, a pin 5 is provided at the connection point of the two ropes. This embodiment does not impose specific limitations on the structure of the connecting rope 14.

[0061] Based on the above, the rope used to form the connecting rope 14 is a steel wire rope.

[0062] Furthermore, in this embodiment, the alarm 13 includes a buzzer 131, which is electrically connected to the circuit board 12. When the anti-theft tag is forcibly cut off the connecting rope 14 without normal unlocking, the first wire 141 and the second wire 142 are cut off, thereby causing the closed circuit to break. The circuit board 12 can then control the buzzer 131 to emit a buzzing sound to alert the staff.

[0063] Furthermore, a first through hole 111 is provided on the outer casing 11 near the buzzer 131. The first through hole 111 communicates with the accommodating cavity 113 and penetrates the outer casing 11, communicating with the outside. This facilitates the transmission of the buzzing sound emitted by the buzzer 131 to the outside, thereby enabling more reliable warning to staff.

[0064] Based on the above description, in this embodiment, the circuit board 12 is provided with a first connection terminal 121, a second connection terminal 122, and a third connection terminal 123. The alarm 13 is electrically connected to the circuit board 12 through the first connection terminal 121. Specifically, the first connection terminal 121 is used to electrically connect the buzzer 131. The first wire 141 is electrically connected to the circuit board 12 through the second connection terminal 122, and the second wire 142 is electrically connected to the circuit board 12 through the third connection terminal 123. This allows the circuit board 12 to sensitively sense when the first wire 141 and / or the second wire 142 are cut, and to sensitively control the buzzer 131 to sound an alarm.

[0065] In addition, the anti-theft tag also includes a battery 3, which is also installed in the cavity 113 and electrically connected to the circuit board 12 to supply power to the circuit board 12.

[0066] Furthermore, in this embodiment, the outer shell 11 is a shell structure integrally formed on the periphery of components such as the circuit board 12 and the alarm 13, and the outer shell 11 wraps the connecting rope 14 near one end of the circuit board 12. Of course, in other optional embodiments, the outer shell 11 may also be formed by detachably assembling at least two shells. This embodiment does not impose specific limitations on this.

[0067] Furthermore, the anti-theft tag also includes a locking groove 41 and a locking block 42. The locking groove 41 is opened inside the housing 11 and connects between the through hole 114 and the receiving cavity 113. The width of the locking groove 41 is greater than the width of the through hole 114. The locking block 42 is disposed on the connecting rope 14. The width of the locking block 42 is greater than the width of the connecting rope 14. The locking block 42 is housed in the locking groove 41. The housing 11 can lock the locking block 42 through the locking groove 41, thereby preventing the connecting rope 14 from detaching from the housing 11, and thus preventing the circuit board 12 from misjudging and controlling the buzzer 131 to sound an alarm.

[0068] Example 2

[0069] like Figures 7 to 9 As shown, compared to Embodiment 1, the difference in this embodiment is that the anti-theft tag also includes a sensor 15. In this embodiment, the sensor 15 is installed inside the housing 11 and can emit a sensing signal. Specifically, the sensor 15 is also installed in the accommodating cavity 113. The sensor 15 is electrically connected to the alarm 13. When someone takes a product with an anti-theft tag out, the alarm system set at the door can sense the sensing signal emitted by the sensor 15 and sound an alarm, thereby reminding the staff.

[0070] It is understood that since the sensor 15 in this embodiment is directly mounted on the alarm device 1 and electrically connected to the circuit board 12, rather than mounted on the locking member 6, this embodiment can save the need to arrange other circuit board 12 structures in the locking member 6, thereby saving the manufacturing cost of the anti-theft tag.

[0071] Of course, in other alternative embodiments, the sensor 15 may also be disposed within the locking member 6. Accordingly, the locking member 6 is provided with a circuit board 12 structure for electrical connection with the sensor 15. This embodiment does not impose specific limitations on this.

[0072] Therefore, in this embodiment, sensor 15 can emit a signal at a preset frequency. For example, in this embodiment, sensor 15 can emit an 8.2MHz sensing signal. When someone takes a product with an anti-theft tag out, the alarm system installed at the door can sense the sensing signal emitted by sensor 15 and sound an alarm.

[0073] Of course, in other alternative embodiments, sensor 15 may also be configured to emit sensing signals of other frequencies, and this embodiment does not impose specific limitations on this.

[0074] In addition, in this embodiment, the alarm 13 also includes a light-emitting element 132, which is also installed in the accommodating cavity 113 and electrically connected to the circuit board 12. The outer shell 11 is provided with a second through hole 112, through which the light-emitting element 132 protrudes from the outer shell 11. When the anti-theft tag is forcibly cut off the connecting rope 14 without normal unlocking, the first wire 141 and the second wire 142 are cut off, thereby causing the closed circuit to break. The circuit board 12 can then control the light-emitting element 132 to emit an alarm light. That is, in this embodiment, the buzzer 131 and the light-emitting element 132 are combined to provide a joint alarm, thereby more reliably alerting staff.

[0075] Of course, in other alternative embodiments, the alarm 13 may also include only a buzzer 131 or a light-emitting element 132, and this embodiment does not impose specific limitations on this.

[0076] For example, in this embodiment, the light-emitting element 132 flashes slowly at a preset frequency during normal operation. When the anti-theft tag is forcibly cut off the connecting rope 14 without normal unlocking, the circuit board 12 controls the light-emitting element 132 to switch to strobe mode. At this time, the light-emitting element 132 flashes rapidly to alert the staff.

[0077] Therefore, in this embodiment, the circuit board 12 is provided with a first connection terminal 121, a second connection terminal 122 and a third connection terminal 123. The alarm 13 is electrically connected to the circuit board 12 through the first connection terminal 121. Specifically, the circuit board 12 is provided with two first connection terminals 121. The two first connection terminals 121 are respectively used to electrically connect the buzzer 131 and the light-emitting element 132. The first wire 141 is electrically connected to the circuit board 12 through the second connection terminal 122, and the second wire 142 is electrically connected to the circuit board 12 through the third connection terminal 123. This allows the circuit board 12 to sensitively sense that the first wire 141 and / or the second wire 142 has been cut, and to sensitively control the buzzer 131 and the light-emitting element 132 to issue an alarm.

[0078] Furthermore, in this embodiment, the outer shell 11 includes a first shell 115 and a second shell 116. The first shell 115 is detachably attached to the second shell 116. The first shell 115 and the second shell 116 form an accommodating cavity 113. That is, the outer shell 11 is a detachable structure, which makes it convenient for staff to replace the battery 3, thereby enabling the anti-theft tag to be reused.

[0079] It is understood that the first housing 115 can be detachably fastened to the second housing 116 by means of snap-fit ​​connection or bolt connection, and this embodiment does not impose specific limitations on this.

[0080] In addition, in this embodiment, a stop block 144 is provided on the connecting rope 14. The width of the stop block 144 is greater than the width of the through hole 114, thereby preventing the connecting rope 14 from being excessively inserted into the outer shell 11.

[0081] Example 3

[0082] like Figures 10 to 13 As shown, and in combination Figure 10 Compared to Embodiment 1, the difference in this embodiment is that the locking structure includes a pin 5, a locking member 6, and a socket 7. The pin 5 is located at one end of the connecting rope 14 located outside the outer shell 11. The locking member 6 is provided with a lock hole 8. The socket 7 is provided on the outer shell 11. The pin 5 can pass through the socket 7 and be inserted into and locked in the lock hole 8. That is, in this embodiment, the socket 7 is provided on the outer shell 11, while the locking member 6 is only provided with a lock hole 8. The pin 5 can pass through the socket 7 and be inserted into and locked in the lock hole 8.

[0083] Specifically, staff can first pass the connecting rope 14 through the part of the product used to hang the anti-theft tag and the socket 7 on the alarm device 1, and then insert and lock the pin 5 of the connecting rope 14 into the lock hole 8, thereby bending the connecting rope 14 and forming a hanging ring 143 between the part of the connecting rope 14 that extends into the outer shell 11 and the socket 7. The anti-theft tag is hung on the product through the hanging ring 143. When the consumer purchases the product, the staff can unlock the pin 5 by controlling the locking element 6, thereby removing the anti-theft tag from the product.

[0084] Example 4

[0085] like Figure 14 and Figure 15 As shown, compared with Embodiment 1, the difference in this embodiment is that the locking structure includes a pin 5 and a lock hole 8. The pin 5 is located at one end of the connecting rope 14 located outside the outer shell 11, and the lock hole 8 is located on the outer shell 11. The pin 5 can be inserted into and locked in the lock hole 8. That is, in this embodiment, the locking structure consists only of the pin 5 and the lock hole 8, and the anti-theft tag consists only of the alarm device 1.

[0086] In this embodiment, the staff can first pass the connecting rope 14 through the part of the product used to hang the anti-theft tag, and insert and lock the pin 5 of the connecting rope 14 into the lock hole 8, thereby bending the connecting rope 14 and forming a hanging ring 143 between the part of the connecting rope 14 that extends into the outer shell 11 and the insertion hole 7, and the anti-theft tag is hung on the product through the hanging ring 143. When the consumer purchases the product, the staff can unlock the pin 5 by controlling the locking member 6, thereby removing the anti-theft tag from the product.

[0087] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
