Description

Technical Field

[0001] This utility model relates to the technical field of wire seals, and in particular to a wire seal with electronic anti-cutting function. Background Technology

[0002] Currently, most common metering devices on the market, such as electricity meters, water meters, gas meters, and price meters, are equipped with sealing devices to prevent installers or users from disassembling, altering, or damaging the internal structural components of the metering device without authorization. Traditional wire seals are mostly purely mechanical structures, typically consisting of a wire and a lock body. Verification of these mechanical wire seals requires close manual inspection of the physical condition of the wire and lock body, resulting in low verification efficiency and susceptibility to misjudgment due to human error. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a wire seal with electronic anti-cutting function.

[0004] This utility model provides a wire seal with electronic anti-cutting function, including a housing and a wire sealing line 3. The housing is composed of an upper square box connected to a lower stepped column. The housing is provided with a receiving groove, and a one-way wire locking device 6 is provided in the receiving groove. One end of the wire sealing line 3 is provided with a rivet tube 5, and one end of the wire sealing line 3 is sealed by the rivet tube 5 installed in the receiving groove. The other end of the wire sealing line 3 can be sealed by the one-way wire locking device 6. An electronic tag 7 is provided at the bottom of the housing. The electronic tag 7 is electrically connected to the one-way wire locking device 6 and the rivet tube 5 through a wire.

[0005] Furthermore, the housing includes a mounting base 1 and a cover 2, the cover 2 being ultrasonically welded to the mounting base 1.

[0006] Furthermore, a groove is provided at the bottom of the stepped column, and the electronic tag 7 is disposed in the groove.

[0007] Furthermore, the bottom of the groove is ultrasonically welded with a cover plate 8 for sealing the electronic tag 7.

[0008] Furthermore, the receiving groove has two through holes for the steel wire sealing wire 3 to pass through, and the bottom of the receiving groove has an extension hole 1.1 located below the one-way locking device 6.

[0009] Furthermore, the steel wire sealing wire 3 is covered with an insulating sleeve 4 that extends into the perforation, and the insulating sleeve 4 blocks the gap between the steel wire sealing wire 3 and the perforation.

[0010] Furthermore, the surface of the insulating sleeve 4 is provided with a code, and the outer surface of the cover 2 is provided with a QR code that is consistent with the code content.

[0011] Furthermore, the bottom of the receiving groove is provided with a lead hole 1.2 for the wire to pass through.

[0012] The advantages of this invention are: it can read information through electronic tags; when the steel wire seal is cut and the seal is broken, the information inside the electronic tag cannot be read, resulting in high verification efficiency and reduced errors from manual judgment; the housing consists of a square box on the upper side connected to a stepped column on the lower side; the electronic tag is a passive electronic tag; during sealing, the steel wire seal is inserted into a one-way locking device to complete the sealing, and the other end of the steel wire seal is locked by a rivet tube. The one-way locking device ensures that the steel wire seal can only enter; when the reader approaches the electronic tag, the electronic tag circuit is activated, and the information inside the electronic tag can be read normally; ultrasonic welding can prevent the disassembly of the cover and plate. One end of the steel wire sealing wire passes through a perforation and connects to the rivet tube. The other end of the steel wire sealing wire passes through another perforation and is inserted into a one-way locking device to complete the sealing. The extension hole can accommodate the steel wire sealing wire passing through the one-way locking device. The insulating sleeve blocks the gap between the steel wire sealing wire and the one-way locking device, preventing the steel wire sealing wire from moving in or out and preventing people from prying open the one-way locking device with a fine needle. The surface of the insulating sleeve is equipped with a code, and the outer surface of the cover is equipped with a QR code that matches the code content. The content corresponding to the above QR code is written into the electronic tag by an RFID code writer. The wire of the electronic tag passes through the lead hole and is connected to the rivet tube and the one-way locking device. Attached Figure Description

[0013] Figure 1 This is a perspective view of the present utility model; Figure 2 This is a cross-sectional view of the present invention before it is sealed. Figure 3 This is a cross-sectional view of the present invention when it is sealed. Detailed Implementation

[0014] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0015] See Figures 1 to 3This utility model provides a wire seal with electronic anti-cutting function, which includes a housing and a wire sealing line 3. The housing is composed of an upper square box connected to a lower stepped column. A receiving groove is provided inside the housing, and a one-way wire locking device 6 is provided in the receiving groove. One end of the wire sealing line 3 is provided with a rivet tube 5, and one end of the wire sealing line 3 is sealed by the rivet tube 5 installed in the receiving groove. The other end of the wire sealing line 3 can be sealed by the one-way wire locking device 6. The one-way wire locking device is existing technology, and its principle can be referred to patent number CN213661124U, patent name is a patent for a lighting wire locking device. However, the core of the one-way wire locking device in this application is not exposed and cannot be adjusted. An electronic tag 7 is provided at the bottom of the housing, and the stepped column is provided. The bottom of the device has a groove, and the electronic tag 7 is placed in the groove and fixed with glue. This electronic tag is a passive electronic tag, meaning it does not have an internal battery. Outside the reader's reading range, the tag is in a passive state. Within the reader's reading range, the tag extracts its power from the radio frequency energy emitted by the reader. Passive electronic tags generally use reflection modulation to transmit tag information to the reader. The content corresponding to the QR code is written into the electronic tag using an RFID programmer. The electronic tag 7 is electrically connected to the one-way locking device 6 and the rivet tube 5 via wires. During sealing, the one-way locking device, rivet tube, and steel wire sealing wire are electrically connected to conduct electricity. During sealing, the steel wire sealing wire is inserted into the one-way locking device to complete the sealing. The one-way locking device allows the steel wire sealing wire to only enter. When the reader approaches the electronic tag, the electronic tag circuit is activated, allowing normal reading of the information within the electronic tag. This method of reader verification is efficient and reduces errors from manual judgment. After cutting the steel wire sealing wire and opening the seal, the electronic tag circuit is disconnected, and the information within the electronic tag cannot be read.

[0016] The housing includes a mounting base 1 and a cover 2, which is ultrasonically welded to the mounting base 1. Ultrasonic welding prevents disassembly of the cover. The mounting base and cover are made of multi-colored materials, which facilitates color management by the customer according to function.

[0017] The bottom of the groove is ultrasonically welded with a cover plate 8 to seal the electronic tag 7. Ultrasonic welding prevents the cover plate from being disassembled.

[0018] The receiving groove has two through holes for the steel wire sealing wire 3 to pass through, and the bottom of the receiving groove has an extension hole 1.1 located below the one-way locking device 6. One end of the steel wire sealing wire passes through the through hole and connects to the rivet tube, and the other end of the steel wire sealing wire passes through the other through hole and is inserted into the one-way locking device to complete the sealing. The extension hole can accommodate the steel wire sealing wire that passes through the one-way locking device.

[0019] The steel wire sealing wire 3 is fitted with an insulating sleeve 4 that extends into the perforation. The insulating sleeve 4 blocks the gap between the steel wire sealing wire 3 and the perforation. The steel wire sealing wire passes through the perforation and is inserted to the bottom of the one-way locking device. The insulating sleeve blocks the gap between the steel wire sealing wire and the one-way locking device, preventing the steel wire sealing wire from advancing or retreating (the insulating sleeve blocks the entry path, and the one-way locking device blocks the retreat path), thus preventing the one-way locking device from being pried open by a fine needle.

[0020] The surface of the insulating sleeve 4 is marked with a code, and the outer surface of the cover 2 is marked with a QR code that matches the code. The QR code on the cover surface is printed by a laser marking machine, and the content corresponding to the QR code is written into an electronic tag by an RFID code writer.

[0021] See Figure 2 , Figure 3 The bottom of the receiving slot has a lead hole 1.2 for the passage of the wire. The wire of the electronic tag passes through the lead hole and is connected to the rivet tube and the one-way locking device.

[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
