Embodiment Construction
[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0023] see Figure 1 to Figure 7 , a watch seal provided by the embodiment of the present invention is installed on the mounting hole 51 of the casing 50 to prevent the casing 50 from being disassembled illegally. The base 20 , the cover 30 fixedly connected to the outer edge of the base 20 , and the radio frequency identification circuit board 40 installed on the base 20 and closed by the cover 30 . The screw 10 includes a threaded rod 11 threadedly connected to the mounting hole 51 and a top cap 12 connected to the threaded rod 11 , and the top cap 12 is provided with a locking groove 13 . A sp...

The invention belongs to the technical field of package, particularly relates to an instrument seal and an instrument information management system provided with the same and aims at solving the problem that an existing instrument seal is easily counterfeited and cannot be subjected to automatic instrument verification when being illegally dismounted. The heavy and complicated work including lead sealing, threading, fixing and the like of the instrument seal is omitted, a threaded rod of a screw is fixedly connected to a mounting hole formed in a shell, a top cap of the screw is clamped and connected to a clamping hook structure of a base, and a radio frequency identification circuit board is mounted on the base and sealed by a cover body and cannot be pulled out unless the instrument seal is destroyed. A fragile arm is arranged between a body and the clamping hook structure on the base and can be destroyed by pulling the body, the body and the cover body are wholly separated from the clamping hook structure and the screw, and the radio frequency identification circuit board cannot be restored after being destroyed. Manual checking is not needed, the inconvenience brought by the fact that each instrument seal is manually inspected to determine whether each instrument seal is illegally dismounted or not is eliminated, and thievery, dismounting and counterfeiting prevention and automatic serial verification of the instrument seals are achieved.
Description
technical field [0001] The invention belongs to the technical field of encapsulation, and in particular relates to a watch seal and an instrument information management system with the watch seal. Background technique [0002] The meter seal is applied to the housing installed with special instruments (such as water meters, electric meters, gas meters, etc.), and is a barrier to prevent illegal disassembly of the housing for theft and destruction, and is an important part to ensure the normal use of special instruments. Most of the surface seals provided by the prior art use a thread-through structure, that is, the lead seal wire passes through the lead seal screw of a special instrument, and the lead seal wire is tightly sealed by lead pellets or plastic surface seals. During use, the lead seal line is easily cut short by criminals and restored with glue, which is difficult to be found. At the same time, the materials and processes for making the lead seal provided by the ...
