A circuit breaker operating handle

Abstract

This utility model belongs to the field of low-voltage electrical technology and discloses a circuit breaker operating handle. The handle includes a circuit breaker body with a rotatably mounted handle, and a closing hole and a opening hole at the bottom. A button is inserted into one end of the handle, and the button has a protrusion inside. A rotating shaft is horizontally slidably mounted inside the handle. One end of the rotating shaft has a return spring between it and the inner wall of the handle, and the other end is inserted into the button and has a spiral groove, on which the protrusion slides. The rotating shaft also has a chamfered groove, and a pin is vertically slidably mounted inside the handle. One end of the pin engages with the chamfered groove, and the other end can be inserted into the closing or opening hole of the circuit breaker body. The rotating shaft has a limit groove, and the top of the handle has a limit opening; their positions correspond when the pin is inserted into the closing hole. Guide blocks on both sides of the button slide within the guide groove of the handle. This utility model combines rotation and linear motion, resulting in a compact structure, small footprint, support for miniaturized electrical equipment design, and ease of operation, effectively improving operational efficiency and accuracy.
