(3. Explanation of operation of the present invention)

  Next, the operation of the lock mechanism 8 of the circuit breaker of the present invention will be described with reference to FIGS. 1, 2, and 13 to 16.

  First, when the road 2 is not blocked by the blocking bar 7, as shown in FIGS. 1 and 2, the free end of the blocking bar 7 rotated so as to be parallel to the road is connected to the metal fitting. 10 and a gate type, and the blocking bar 7 is fixed so as not to rotate (FIG. 4A).

  At this time, since the blocking bar 7 does not rotate to the side orthogonal to the road and does not press the pushed-up member 14, the pushed-up member 14 of the lock mechanism portion is, as shown in FIG. It is provided vertically hanging by gravity.

  Next, when the free end of the blocking bar 7 is released from the metal fitting 10 and the blocking bar 7 is rotated toward the other side of the road 2 by, for example, a hand or the like, FIG. As shown in the drawing, the distal end pressing portion (pressing portion) of the pressing member 19 of the blocking bar mounting member 13 is connected to the back surface (blocking bar) of one side (the leading side of the blocking bar) of the pushed-up member 14. Therefore, the pushed-up member 14 is pressed forward, so that the pushed-up member 14 pivots upward (FIG. 4B). ).

  Further, when the blocking bar 7 is rotated, the distal end pressing portion of the pressing member 19 of the blocking bar mounting member 13 reaches the lower side of the pushed-up member 14, and the lower side is moved to the left side in FIG. 15 (the direction opposite to the tip direction of the blocking bar 7), and then, as shown in FIG. 15, the inclined pressed portion 18 of the projecting member 16 is moved ((c in FIG. 4). ).

  Then, by moving the upper edge of the blocking bar mounting portion 14 to the recess 17, the upper edge of the blocking bar mounting member 14 fits into the recess 17 as shown in FIG. 16. ((D) of FIG. 4).

  As a result, the blocking bar 7 cannot rotate, and the blocking bar 7 is locked perpendicular to the road 2.

  In order to release the lock of the blocking bar 7, the pushed-up member 14 is rotated upward by hand or the like to release the upper edge of the blocking bar mounting member 13 from the recess 17. Accordingly, the blocking bar 7 can be turned to one side of the road 2.

  In addition, the position of the concave portion 17 may be movable in the left-right direction of the tip side (lower side) of the pushed-up member 14, so that the position of the tip of the blocking bar may be adjusted.

  According to the present invention, the locking bar 7 can be easily locked with a simple mechanism only by tilting the blocking bar 7 to 90 degrees.
