Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

As shown in fig. 1, the utility model provides a pair of electric power measurement cabinet lead sealing lock, including tapered end 1, lock core 2, mounting nut 3, spring bolt 4 and fixing bolt 5, lock core 2 rotationally installs in tapered end 1, mounting nut 3 suit is in on the outer wall of tapered end 1, be equipped with outside bellied square boss 2a on the bottom surface of lock core 2, spring bolt 4 suit is in on square boss 2a, just spring bolt 4 passes through fixing bolt 5 compresses tightly installs on lock core 2, radially be equipped with lock core through-hole 2b on the lock core 2, correspond on the tapered end 1 the position at lock core through-hole 2b both ends is equipped with a tapered end through-hole 1a respectively.
