Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings: as shown in the figure, the one-way operating mechanism for a circuit breaker includes a bracket 1, and a rotatable operating rod 2 is provided on the bracket 1, and the operating rod 2 is covered A transmission gear 3 with a movable fit is provided, and a unit for driving the transmission gear 3 to rotate when the operating lever 2 rotates in the forward direction, and to drive the transmission gear 3 to rise or fall when the operating lever 2 rotates in the reverse direction. to the institution. The invention provides a one-way operating mechanism for a circuit breaker and a circuit breaker. A rotatable operating rod is provided on the bracket, and a movable and cooperating transmission gear is set on the operating rod. The operating rod is used to drive the transmission gear when rotating forward. The gear rotates, and when it rotates in the opposite direction, it dri...

Abstract

A unidirectional operating mechanism for circuit breakers and a circuit breaker are provided. The unidirectional operating mechanism mainly solves a problem that the transmission gears of the manual operating mechanisms of conventional circuit breakers are mostly unidirectional transmission gears, and are in stuck states when rotating backwardly and are easy to damage in the case of excessively large force. The present invention provides a unidirectional operating mechanism for circuit breakers and a circuit breaker, wherein the bracket of the unidirectional operating mechanism is provided with a rotatable operating rod sleeved by a transmission gear in clearance fit. The operating rod is used for driving the transmission gear to rotate when rotating forwardly, and drives the transmission gear to ascend or descend when rotating backwardly. The operating rod normally drives the main gear of the circuit breaker to rotate when rotating forwardly, and drives the transmission gear to ascend or descend when rotating backwardly so as to be away from the main gear, thereby preventing stuck damage and achieving a long service life.

Description

technical field [0001] The invention belongs to the field of circuit breakers, in particular to a one-way operating mechanism for the circuit breaker and the circuit breaker. Background technique [0002] A circuit breaker is a current switching device used to distribute electric energy and protect power lines and motors in real time. The current in the circuit, so as to ensure the safety of production. [0003] Molded case circuit breaker, as a kind of circuit breaker, uses a plastic insulator as the casing of the device, and can also automatically cut off the current when the actual current exceeds the trip setting value. In the actual working process, the molded case circuit breaker is equipped with an opening and closing mechanism, a manual operating mechanism and an automatic operating mechanism for controlling the opening and closing mechanism. Most of the transmission gears of the current manual operating mechanism are one-way transmission, but It is stuck in a stuc...
