It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0043] like Figure 1 As shown, the easy-to-assemble anti-theft tag includes a tag cover 1 and a retractable unit connected to the tag cover;

[0044] The retractable unit is one of the following structures:

[0045] 1. Mesh bag: The closing rope of the mesh bag is connected to the label cover. The mesh bag is made of wire and can hold irregular goods;

[0046] 2. Net bag and base: The closing rope of the net bag is connected to the label cover, and the base is fixed to the net bag. The net bag is made of wire and can hold bottled goods;

[0047] 3. Retractable rope and base: The retractable rope connects the label cover and the base. The retractable rope is made of a wire and can be used to place canned goods.

[0048] The label cover comprises a housing, a rotating member, a lock core mechanism, a one-way rotation mechanism, a circuit assembly, and a coil. The housing comprises an upper housing 1-1 and a lower housing 1-2. The rotating member comprises a top cover 1-3 and a winding reel 1-4. The lock core mechanism comprises a lock head 14-1, a lock head spring 14-2, and a fixed cover 14-3. The rotating member is rotatably positioned in the housing, the one-way rotation mechanism is arranged between the housing and the rotating member, and the wire is wound around the rotating member and electrically connected to the circuit assembly.

[0049] When locking, the lock core mechanism locks the one-way rotation mechanism, and the rotating part can only rotate in one direction (continuously taking in the wire).

[0050] The above structure is the same as the prior art. The improvement of the utility model is:

[0051] 1. The one-way rotation mechanism comprises a long connecting rod 3, a connecting frame 4, a tooth connecting rod 5, a long connecting rod spring 6, a tooth connecting rod spring 7, and a gear ring 8. The long connecting rod spring is used to push the long connecting rod, and the long connecting rod pushes the tooth connecting rod through the tooth connecting rod spring, and the tooth connecting rod is provided with a tooth head meshing with the gear ring.

[0052] like Fig.21 As shown, the gear ring is made on the inner wall of the upper shell. The inner wall of the upper shell is also provided with a groove 1-1-1, and the RFID tag 13 is fixed in the groove.

[0053] The long connecting rod, the tooth connecting rod and the tooth connecting rod spring are integrated into one body through a connecting frame. The connecting frame is arranged between the long connecting rod and the tooth connecting rod, the connecting frame is fixed to the long connecting rod, the tooth connecting rod can be slidably positioned on the connecting frame, and the tooth connecting rod spring is arranged between the connecting frame and the tooth connecting rod.

[0054] like Fig. 9 As shown, the long connecting rod is provided with two slots 3-1, such as Fig.10 As shown, the connecting frame is provided with two hooks 4-1 which are plugged into and matched with the slots. The hooks are inserted into the slots so that the connecting frame is fixed to the long connecting rod.

[0055] like Fig.10 As shown, the baffles 4-4 on both sides of the connecting frame are provided with slide grooves 4-2, such as Fig.11 As shown, sliders 5-1 slidably matched with the slide grooves are provided on both sides of the toothed connecting rod, and the toothed connecting rod can be slidably positioned between the baffles.

[0056] like Fig.10 As shown, the connecting frame is provided with a connecting frame boss 4-3, and the connecting frame boss is located between the baffles on both sides, such as Fig.11 As shown, the toothed coupling rod is provided with a toothed coupling rod boss 5-2, and the toothed coupling rod is also provided with a spring groove 5-3 for accommodating a toothed coupling rod spring, the toothed coupling rod boss is located in the spring groove, the toothed coupling rod spring is arranged in the spring groove and the two ends respectively support the connecting frame boss and the toothed coupling rod boss.

[0057] Since the long connecting rod, the connecting frame, the tooth connecting rod and the tooth connecting rod spring are connected as a whole, they can be pre-assembled, which greatly simplifies the later production process and improves the production speed.

[0058] The lock core mechanism (lock head and lock head spring) and the one-way rotation mechanism (long connecting rod, connecting frame, tooth connecting rod, long connecting rod spring, tooth connecting rod spring) can also be pre-installed in the upper shell to further simplify the later production process.

[0059] 2. The circuit assembly includes a circuit board 9, a battery 10, a positive pole spring 11, and a negative pole spring 12.

[0060] The circuit board is fixed on the top of the winding drum by screws, the battery is installed on the bottom of the winding drum, and the circuit board and the battery are electrically connected through a positive pole spring and a negative pole spring.

[0061] The winding drum has an upper cavity 1-4-4 on the top surface and a lower cavity 1-4-5 on the bottom surface. The circuit board is fixed above the upper cavity, and the battery is installed in the lower cavity. The lower cavity is also provided with a battery cover 1-5.

[0062] The winding drum is provided with two through holes 1-4-3, the positive pole spring and the negative pole spring are arranged in the through holes and the two ends extend into the upper cavity and the lower cavity respectively to support the circuit board and the battery, the two ends of the positive pole spring are respectively electrically connected to the positive pole of the battery and the circuit board, and the two ends of the negative pole spring are respectively electrically connected to the negative pole of the battery and the circuit board.

[0063] Since the circuit board and the battery are directly connected by the positive spring and the negative spring, there is no need to weld the leads. The winding reel, battery, and battery cover are assembled in advance, and the positive spring and the negative spring are installed when the circuit board is installed later, which greatly simplifies the later production process and improves the production speed.

[0064] 3. Fig.15 As shown, the side wall of the winding drum is provided with two wire grooves 1-4-2, and two wires respectively pass through the wire grooves and extend into the upper cavity and connect to the circuit board.

[0065] like Fig.18 As shown, conductive studs 2 - 1 are respectively provided at both ends of the wire, and the conductive studs are made of copper and have a rectangular cross section.

[0066] The top surface of the winding disk (upper cavity) is provided with two rectangular installation grooves 1-4-1. The wire first passes through the wire groove and extends into the upper cavity, and then is wound along the inner wall of the upper cavity. The conductive column head is then inserted into the installation groove. At the same time, the circuit board presses the conductive column head, and the conductive column head and the circuit board are fixed by conductive glue (omitted in the figure) to form an electrical connection.

[0067] Since there is no need to weld leads between the circuit board and the wires, the subsequent production process is greatly simplified and the production speed is improved.

[0068] The bottom surface of the circuit board is provided with a copper sheet contacting the positive pole spring, the negative pole spring and the conductive column head.

[0069] The preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
