Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to an operating device for control equipment. More specifically, the present invention relates to an improvement in an operating device for a control device that converts the rotational movement of an external operating handle of a control device such as a circuit breaker in a control center or the like into an ``on'' or ``off'' operation of the control device.

[Prior art and its problems]

When a control device such as a circuit breaker is housed in a box such as a control center, the operating handle of the control device should be cut out of the door and exposed on the front of the box so that it can be operated externally with the door closed. Placed. The operating handle is used to turn on and off a circuit breaker, etc. with the door closed. A switch lever of a circuit breaker or the like has a reciprocating rocking motion from the viewpoint of movement, but a reciprocating linear motion from the viewpoint of applying operating force. The switch lever is therefore designed to withstand forces operated by reciprocating linear forces.
In other words, it is natural to operate with the force of reciprocating linear movement, and no unreasonable force is applied. From the viewpoint of extending product life, the switch lever should be operated by reciprocating linear force. By the way, Japanese Patent Application Laid-Open No. 54-86772 or Jikkosho
No. 38-15258 discloses an operating device for operating a control device such as a circuit breaker. The operating device disclosed in the former publication rotates a link member, which is rotatably attached by a support pin and has a protruding pin for operating a circuit breaker, about the support pin via a lever member. , the circuit breaker is turned on and off by the action of the pin. However, since this operating device turns the circuit breaker on and off by rotating the link member, the operating force cannot be sufficiently transmitted to the switch lever of the control device, which moves linearly in a reciprocating manner. However, there is a problem in that unnatural and unreasonable force is applied, shortening the product's lifespan. The operating device disclosed in the latter publication has the base of a swinging thin metal plate pivoted with a pin, a U-shaped notch formed at the tip, and a pair of rollers supported on both sides of the notch. A knob is placed between these rollers, and the control device is turned on by swinging it around the pin.
It has a “cut” structure. In this structure, the control equipment is turned on and off by rotating the swinging thin plate metal fitting, and the rollers are used to prevent excessive force from being applied to the switch lever. Better than the previous device. However, the operating force on the switch lever is a rotational movement, and not only is the operating force not sufficiently transmitted, but unnatural and unreasonable force is applied.
This cannot be said to be sufficient from the viewpoint of extending product life. In addition, none of the above-mentioned operating devices are designed to be able to immediately respond to changes in model when the model is changed due to design changes or the like during assembly.
