Abstract

The present disclosure relates to a handle operating device for a circuit breaker, and there is provided a handle operating device including a connecting rod configured to transfer power for operating a manual operating handle that manually operates the on/off of a circuit breaker from the outside; a movable frame connected to the connecting rod to be movably coupled to an outer surface of a circuit breaker case in a direction parallel to the operating direction of the manual operating handle; a movable member provided at the movable frame in an interlocking manner to move the manual operating handle; a slot hole is formed on the moving member in an inclined manner from the moving direction of the manual operating handle; and a fastening member fastened to the movable member and movable frame through the slot hole.

First claim

What is claimed is:

1. A handle operating device, comprising:
a connecting rod configured to transfer power for operating a manual operating handle that is used for manually operating on/off of a circuit breaker from outside;
a movable frame connected to the connecting rod to be movably coupled to an outer surface of a circuit breaker case in a direction parallel to an operating direction of the manual operating handle;
a movable member provided at the movable frame in an interlocking manner to move the manual operating handle;
slot holes formed on the moving member in an inclined manner from the operating direction of the manual operating handle to adjust a gap of the manual operating handle; and
a fastening member inserted into one of the slot holes to fasten the movable member to the movable frame,
wherein the movable member is provided with an insertion hole therein to insert an end portion of the manual operating handle, and
wherein a rear gap between the movable member and the manual operating handle is reduced when increasing a front gap between the movable member and the manual operating handle, or the front gap between the movable member and the manual operating handle is reduced when increasing the rear gap between the movable member and the manual operating handle.

2. The handle operating device of claim 1 , wherein the fastening member is a screw.

3. The handle operating device of claim 1 , wherein the fastening member is configured to finely adjust an operating distance of the manual operating handle according to a position at which the fastening member is fixed on the one of the slot holes.

4. The handle operating device of claim 1 , wherein:
the movable frame comprises:
side plates coupled to an outer surface of the circuit breaker case, each side plate having a hinge structure, and connected to an end portion of the connecting rod to be rotated in the same direction as the operating direction of the manual operating handle; and
movable rods connected between the side plates to be operated along with the side plates; and

the movable member is connected between the movable rods.

5. The handle operating device of claim 1 , wherein the slot holes are formed in parallel to each other with a gap therebetween.

6. The handle operating device of claim 1 , wherein the slot holes are formed on the movable member to be separated from each other in a vertical direction of the movement of the movable member.

7. The handle operating device of claim 1 , wherein the slot holes are formed on the movable member to be separated from each other in a movement direction of the movable member.
