Detailed Description

As shown in fig. 1-3, an ABB contactor is joined in marriage to electronic chassis car, including lead screw 1, first signal spare 2 and second signal spare 3, lead screw 1 drives first signal spare 2 or second signal spare 3 trigger circuit through axial displacement, lead screw 1 axial one end department is equipped with hand wheel 4, still includes drive assembly, first link assembly and second link assembly, drive assembly includes motor 5, chain belt 6 and drive gear 7, through chain belt 6 and drive gear 7 synchronous motion between motor 5 and the lead screw 1, first link assembly and second link assembly all include head and tail swing joint's driving rod 8, transition rod 9 and driven lever 10 in proper order, be equipped with on the lead screw 1 through rotating the butt portion 11 of butt driving rod 8, and butt portion 11 drives the signal circuit of driving rod 8 action trigger first signal spare 2 or second signal spare 3. In this embodiment, the motor 5 is provided to drive the screw 1 to perform an axial reciprocating motion, and the subsequent linkage triggering structure of the screw 1 is a mature technical means, which is not described and limited herein. The motor 5 is matched with the chain belt 6 and the transmission gear 7 to carry out transmission synchronization, so that the transmission distance of the chain belt 6 can be prolonged without arranging a plurality of transmission gears 7 and increasing transmission loss. The first signal element 2 and the second signal element 3 are main action components of the trigger circuit and are also mature technical means, and the difference here is that stable linkage is performed through an assembly with three sub-rods. It should be noted that, in this embodiment, the screw 1 is axially displaced by the screw rotation, and meanwhile, there is a force applied in the radial direction, so that the abutting portion 11 can be driven to drive the driving rod 8 to move transversely.
