The invention discloses a position locking device of a molded case circuit breaker with an operating mechanism. The position locking device of the molded case circuit breaker with the operating mechanism comprises a molded case circuit breaker, an operating mechanism and a position locking device arranged in the operating mechanism; the position locking device comprises a base and a slide seat; an operating groove opening is formed in a part of a cover cap of the operating mechanism corresponding to the slide seat; a through hole is formed in the end part of the operating groove opening; a slide groove is formed on the base, and a round hole is formed in the base corresponding to the through hole; the lower part of the base is provided with a microswitch; the slide seat comprises a seat body; a hole is formed in the seat body, and the lower end of the seat body is provided with a slide block matched with the slide groove; the lower end of the slide block is connected with a press block, and one end of the slide block is provided with a convex circular arc surface; the middle section of the slide groove is provided with a concave circular arc surface matched with the convex circular arc surface. According to the invention, the middle section of the slide groove is provided with the concave circular arc surface matched with the convex circular arc surface, so that the middle locking position is added, the molded case circuit breaker with the operating mechanism can achieve a position locking function, and the safety in safe overhauling is improved.
Description
technical field [0001] The invention relates to a position lock device of a molded case circuit breaker, in particular to a position lock device of a molded case circuit breaker with an operating mechanism. Background technique [0002] Molded case circuit breaker is a device that can automatically cut off the current after the current exceeds the trip setting. When the existing molded case circuit breaker is not equipped with an operating mechanism, it is generally possible to hang a position lock device on the panel to lock the position of the molded case circuit breaker, which is convenient for maintenance personnel to safely overhaul; however, when the operating mechanism is installed , the operating mechanism generally only has two positions of electric and manual, and because the operating mechanism is generally hung on the body of the molded case circuit breaker, it occupies the space of the position lock device, making the position locking function of the molded case...
