Problems solved by technology

[0004] After adopting the above method, because there is inevitably a gap between the connecting piece 90 and the front wall drive shaft 84, and when the switching device passes through the dead point position, the front wall drive shaft 84 bears a large moment, and the synchronization effect may be affected. influences
In addition, since the drive shafts of each switching device are generally designed to withstand the torque generated by only one switching device, the drive shaft may be damaged in the above connection mode.

Abstract

The invention discloses a linkage mechanism of a switching device group. The linkage mechanism comprises a rotatable linkage rod (10) and a plurality of linkage components (20), wherein each linkage component comprises a swing piece (22), a sliding piece (24) and an execution piece (26); the swing pieces can be fixed with the linkage rod, and are provided with swing ends (222) capable of rotating along with the linkage rod; the sliding pieces are provided with first contact parts (242) and second contact parts (246); the first contact parts are contacted with the swing ends; the execution pieces can be fixed with a driving shaft of a switching device, and are provided with execution ends (266) capable of rotating along with the driving shaft; the execution ends are contacted with the second contact parts; the rotatable swing ends can push the sliding pieces to move in a linear direction by the first contact parts; and the second contact parts of the sliding pieces can push the driving shaft to rotate between an off position and an on position by the execution ends. The linkage mechanism can realize synchronous operation of multiple switching devices, is good in synchronous effect, and can avoid damage of the driving shaft.

Description

technical field [0001] The present invention relates to a linkage mechanism, in particular to a linkage mechanism of a switching device group, and also to a switching device group having the above linkage mechanism. Background technique [0002] In the switching device, by operating the drive shaft to switch between the open position and the closed position, the drive shaft is driven to make the movable contact and the fixed contact contact and separate, so as to realize the on-off control of the power supply line. like figure 1 As shown, the drive shaft of the switching device can generally be designed as a front wall drive shaft 84 perpendicular to the axial direction of the transmission shaft 82 or a side wall drive shaft 86 parallel to the axial direction of the transmission shaft 82 . [0003] When it is necessary to realize the synchronous operation of two or more switching devices, taking two switching devices as an example, due to the limitation of structure arrange...
