Direct-acting electromagnetic trip device

A direct-acting electromagnetic trip device, comprising a housing, and a regulation mechanism, a linkage mechanism, an electromagnetic system and a trip mechanism which are arranged in the housing, wherein:

• 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;
• when the electromagnetic system has a tripping current inside, the iron core of the electromagnetic system actuates to drive the linkage mechanism, and the linkage mechanism drives the trip mechanism to complete a tripping action;
• the regulation mechanism comprises 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 comprises an elastic element, and the elastic element 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;
• and
• the rotary knob is rotated to trigger the regulation rod to move upwards and downwards to drive the movement of the linkage mechanism, such that the linkage mechanism drives the iron core to move upwards and downwards to regulate a tripping current of a product,
• wherein the linkage mechanism is located below the regulation mechanism, the electromagnetic system is located below the linkage mechanism, and the trip mechanism is located on one side of the linkage mechanism;
• wherein the direct-acting electromagnetic trip device further comprises a support and a fixed shaft, and
• wherein the regulation rod is mounted on the support through the fixed shaft and can move upwards and downwards along the fixed shaft.
