However, because it uses a push-down padlock mechanism, the padlock plate needs to be pushed down to be padlocked, which means that the handle height dimension is large
And this is contrary to the general demand of customers for reducing the thickness of the switchgear
[0006] In addition, in the prior art, there is also a circuit breaker based on a pull-out padlock mechanism, but it uses a lever mechanism, which has a complex structure, many parts, and high manufacturing costs

The present disclosure provides a padlock interlock for a rotary handle and a rotary handle. The padlock interlocking device may include: a padlock plate fixed to the handle head of the rotary handle in a manner capable of sliding between a padlock position and an unlocked position of the padlock plate; and a handle panel, the handle The faceplate includes a retaining ring protruding therefrom. The padlock plate includes a side plate and a lock post on an opposite side of the side plate. The side panel is configured to cover a fastening member for fastening the handle head when the padlock plate is in the padlock position, and to expose the fastening member when the padlock plate is in the unlocked position . The lock cylinder and the retaining ring have mutually cooperating structures to restrain the padlock plate in the unlocked position during operation of the rotary handle. Through the embodiments of the present disclosure, a padlock interlocking device and a rotary handle with small size, simple structure and low cost can be provided.
Description
Technical field [0001] The embodiment of the present disclosure relates to a rotary handle, and more specifically to a padlock device for the rotary handle and a rotary handle including the padlock interlock device. Background technique [0002] At present, rotary handles are widely used for manual operation of switchgear such as circuit breakers. The rotary handle can be installed directly on the switch equipment in the switch cabinet or on the door of the switch cabinet. The rotating handle includes a shaft that can be coupled with the switch device to operate the switch device. In the operating state, the rotary handle can be manually operated by the operator to rotate between the off position and the closed position of the electrical equipment. The shaft of the rotary handle will rotate with the rotary handle, and then the shaft is connected to the other end of the shaft. Switch device to operate. When the rotary handle needs to be locked, the rotary handle can be locked b...
