<p>Disclosed herein is a sealing device for a coupling bolt of a cover or terminal box of a meter (3). The sealing device makes it possible to use a typical coupling bolt as a sealing bolt without requiring a separate sealing wire and a special sealing bolt. Typically, in the conventional technique, at least two to four coupling bolts are used to couple a cover which protects a counting machine of various meters, wherein one or two bolts are special sealing bolts. In the present invention, a typical coupling bolt functioning as a sealing bolt can be used in such a way that it is tightened into the meter after passing through a sealing cap (20), and a sealing lock (30) is threaded into the sealing cap to prevent the sealing bolt fi'om being exposed to the outside, thus making it impossible to remove the sealing bolt from the meter.</p> |
