直动式电磁脱扣装置
Abstract:
一种直动式电磁脱扣装置，包括壳体和置于壳体内部的调节机构、联动机构、电磁系统和脱扣机构。调节机构与联动机构连接，联动机构与电磁系统的铁芯的一端连接，联动机构同时与脱扣机构连接；当电磁系统内存在脱扣电流时，电磁系统的铁芯动作带动联动机构，联动机构带动脱扣机构完成脱扣动作；调节机构包括旋钮和调节杆，旋钮与调节杆抵接配合，调节杆与联动机构抵接配合，电磁系统还包括弹性元件，弹性元件推动铁芯使得联动机构与调节杆抵接在一起且旋钮与调节杆抵接在一起；转动旋钮可触发调节杆上下运动带动联动机构动作，使得联动机构带动铁芯上下动作来调节产品的脱扣电流。结构简单紧凑，性能安全稳定，便于装配。
Abstract(English):

A direct-acting electromagnetic trip device including a housing, and a regulation mechanism, a linkage mechanism, an electromagnetic system and a trip mechanism which are arranged in the housing. The regulation mechanism is connected with the linkage mechanism, the linkage mechanism is connected with one end of an iron core of the electromagnetic system, and the linkage mechanism is connected with the trip mechanism at the same time. The regulation mechanism includes a rotary knob and a regulation rod, wherein the rotary knob is abutted against and engaged with the regulation rod, and the regulation rod is abutted against and engaged with the linkage mechanism. The electromagnetic system further includes an elastic element that pushes the iron core to allow the linkage mechanism to be abutted against the regulation rod and allow the rotary knob to be abutted against the regulation rod.
