Description

Technical field [0001] The invention relates to a switch operating mechanism, in particular to a dual power switch operating mechanism. Background technique [0002] The existing dual power switch operating mechanism includes a housing, a rotating bracket, an acting part, a sheave and a sliding block. The rotating bracket, the acting part, the sheave and the sliding block are linked together. The rotating bracket has an action hole, the action part and the action hole. In cooperation, the sheave wheel is provided with a sheave wheel guide hole, and the sliding block is located in the sheave wheel guide hole. Since the acting part can only move laterally, that is, it can only move in the x coordinate direction and cannot move in the longitudinal direction, that is, it is in y There is no displacement in the coordinate direction. Therefore, there are the following defects. There is no movable gap between the effective hole and the effective member, and the effective hole and the ef...

[0002] The existing dual power switch operating mechanism includes a housing, a rotating bracket, an active part, a sheave and a slider, and the rotating bracket, the active part, the sheave and the sliding block are linked together, and the rotating bracket has an action hole, and the action part and the action hole Matched, the sheave is provided with a sheave guide hole, and the slider is located in the sheave guide hole. Since the active part can only move horizontally, that is, it can only move in the x coordinate direction, and cannot move in the longitudinal direction, that is, it can move in the y coordinate direction. There is no displacement in the coordinate direction, so there are the following defects. There is no movable gap between the active hole and the active part, and the active hole and the active part cannot move longitudinally relative to each other. Since the rotation track of the rotating bracket is an arc, it is necessary to require the active part to be in the There will be movement in the longitudinal direction, that is, there will be displacement in the y coordinate direction, otherwise it will form an operation dead zone, which will make the rotation of the rotating bracket difficult. The current existing structure requires a lot of force to operate the rotating bracket, making it rely on unnecessary Due to the rotation of the assembly gap, the operation mechanism of the double power switch will make an error, and the power supply cannot be switched in time. The block drives the sheave to rotate to complete the closing action, but there are the following defects. During the closing action, the slider needs to abut against the two sides of the guide hole of the sheave to make the sheave complete the closing action, and the two sides Form an included angle, that is to say, the original slider abuts against one side and pushes it, and also abuts against the other side to push it. When the slider is between these two sides, the slider At the same time, it abuts against these two sides and pushes them, which disperses the driving force of the slider and increases the rotation resistance of the sheave, resulting in the slider needing a greater driving force to push the sheave to rotate, eventually resulting in the entire dual power supply The switch operating mechanism is difficult to operate
