Description

Anti-breaking and anti-disassembling alarm lead seal for gas meter Technical Field The utility model relates to the technical field of anti-theft and anti-tearing-open technology of commercial gas meters in town gas industry, in particular to an anti-tearing-open alarm lead seal for a gas meter. Background At present, one common gas stealing means of industrial and commercial gas users is to tamper with parameters of a gas meter privately, destroy a counting structure of the gas meter, the means needs to manually open the gas meter and destroy the original lead seal, the traditional lead seal adopts a metal sealing mode, the theft resistance is poor, management personnel are required to periodically inspect the lead seal state to discover gas stealing behavior, meanwhile, the traditional metal lead seal has no copy-proof function, and the gas stealing part can copy and forge the metal lead seal to avoid discovery of inspection personnel. The RFID lead seal upgraded on the basis of the traditional lead seal has the anti-copying function, so that the lead seal can be prevented from being copied to a certain extent, but the phenomenon of gas theft can be discovered only by detecting the lead seal by using a special tool when a patrol personnel is required to carry out daily patrol, and the specific date of gas theft cannot be positioned. Therefore, a novel electronic lead seal capable of effectively preventing the gas stealing part from copying the lead seal information, recording the occurrence date of the gas stealing behavior of the meter disassembly and actively reporting to the manager after the gas stealing behavior, and not needing the on-line inspection of the inspection personnel is needed. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides an anti-tearing alarm lead seal for a gas meter, solves the problems of gas loss caused by gas theft of a gas company in the prior art, monitors illegal behaviors and reduces public safety risks. Technical support is provided for gas inspection, and the problem of compensation is pursued. The Bluetooth slave machine and the host machine adopt Bluetooth communication, the Bluetooth slave machine is arranged in the shell, a battery, a main board and a wire sealing line are arranged in the Bluetooth slave machine, a circuit board is arranged in the shell, a wire-collecting unidirectional snap ring pole piece is arranged on the circuit board, the wire sealing line can be inserted into the wire-collecting unidirectional snap ring pole piece, a metal spike of the unidirectional snap ring pole piece can be clamped on the wire sealing line, and a sampling resistor sealing strip which extends out through a wire-outlet snap ring and is fixed on the circuit board is arranged on the circuit board. Preferably, the sealing wire is made of conductive plastic (graphite fiber) and is externally measured as an insulating sheath. Preferably, the sampling resistor seal is made of conductive plastic, and the outer skin is wrapped by an insulating sheath. Preferably, the shell is made of ABS engineering plastic. Preferably, the circuit board is provided with a battery directly connected with the battery seat. The utility model provides an anti-tearing alarm lead seal for a gas meter. The gas theft alarm device has the advantages of compact structure, small and exquisite equipment, strong theft resistance, irreproducibility and irreparable repair, records the time of destroying the stolen gas, provides basis for tracing the gas theft, actively reports the gas theft, reduces the inspection frequency of an administrator, and saves the labor cost.
