1. A distributing board having a position lock device comprising:
an enclosure and an electric device unit configured to be drawn in and out of the enclosure,
a positioning bracket having;
a concave and convex part fixed to the enclosure and configured to set a position of the electric device unit, the concave and convex part includes a plurality of convex portions and concave portions formed alternately, wherein the plurality of concave portions and concave portions include a first convex portion, a first concave portion, a second convex portion, a second concave portion, a third convex portion, and a third concave portion sequentially formed from one end of the positioning bracket, and wherein the first concave portion, the second concave portion, and the third concave portion correspond to a disconnect position, a test position, and a service position of the electric device unit, respectively, and wherein adjacent ones of the convex and concave portions of the plurality of concave portions and concave portions are connected by an inclined surface, and
a test position looking groove corresponding to the test position and a service position locking groove corresponding to the service position are formed on an upper surface of the positioning bracket; and
a locking device coupled to a portion of the electric device unit to move together with the electric device unit, and configured to be locked or unlocked to or from each position of the positioning bracket so as to inhibit or allow movement of the electric device unit.
 
2. A distributing board having a position lock device comprising:
an enclosure and an electric device unit configured to be drawn in and out of the enclosure,
a positioning bracket having a concave and convex part fixed to the enclosure and configured to set a position of the electric device unit; and
a locking device coupled to a portion of the electric device unit to move together with the electric device unit, and configured to be locked or unlocked to or from each position of the positioning bracket so as to inhibit or allow movement of the electric device unit, wherein the locking device includes:
a case;
an upper locking member installed at the case to be movable up and down, so as to slide along an upper surface of the positioning bracket when the electric device unit is drawn in and out of the enclosure;
a lower locking member rotatably installed at the case to slide along a lower surface of the positioning bracket when the electric device unit is drawn in and out of the enclosure; and
a release plate installed on the case to move linearly in a direction orthogonal to a movement direction of the upper locking member, so as to release locking of the upper locking member,
wherein an indicator hole having an arcuate shape is formed on a side surface of the case, the indicator hole configured for viewing an indicator of the lower locking member; and
an operation member that provides a force for operating the release plate, wherein operation holes are formed on upper and lower surfaces of the case, respectively, so as to allow a portion of the upper locking member to move up and down.
