Description
Technical field
The utility model belongs to switching technique field, is exactly specifically to be related to a kind of operating mechanism of rotary switch.
Background technology
The word explanation of switch is to open and close.It, which refers to one, can make open circuit, make current interruptions or make it
Flow to the element of other circuits.It is most common switch be allow people operate electromechanical equipment, wherein there are one or several contacts.Contact
" closed " (closed) indicate contact conducting, allow electric current flow through；" open circuit " (open) of switch indicates that contact is not turned on shape
At open circuit, electric current is not allowed to flow through.The developing history of switch is developed to from the original knife switch for needing manual hand manipulation
The present intelligent switch applied in various large electric control devices, the function of switch is more and more, and safety is also got over
Come higher, rotary switch is a kind of common switch, by the way that rotary operator to be locked in the spy with rotary operating device
The corresponding specific position of state is determined to prevent rotary operating device from being operated without permission.However, if rotary operator is locked
It is scheduled on a home, and the operation part of rotary operating device is not at corresponding required state, then will appear unsafe condition.
For example, certain in the rotary electric switch of fixing electric contacts and the rotation electrical contact being installed on axis, contact is " even
It is logical " state has been fused together, and still can rotate rotary operator using the torsion of axis and lock it in phase
It should be in the position of off-state.Therefore, switch looks like "off", however in fact circuit is still " connection ".
In order to avoid there is the position shown and actual connecting and disconnecting of the circuit state not in the operating mechanism of above-mentioned rotary switch
Unanimous circumstances occur, and many switches, which are taken to lock the physical location of circulator, at present carrys out limit switch operating mechanism shape
Condition it is unstable, such as Chinese patent CN104040662A disclose a kind of displacing system for rotary switch include shell,

Or more relative angular position.Displacement tool includes at least one first displacement part；First displacement part is relative to rotation axis
Substantially tangentially and/or horizontally extend, it at least partially can be reversible between the first radial position and the second radial position
It moves on ground.In the first radial position, displacement tool cooperates to prevent shell and slave unit around the opposite of rotation axis
Rotation.In the second radial position, displacement tool allows shell and slave unit around rotation axis relative rotation.The rotation is opened
The displacing system of pass has to rotating mechanism physical location into line-locked function, but the locking is opposite by additionally increasing
What the locking mechanism answered was completed, the volume and production cost of product are increased, and locking function parts are related to folding floodgate part
Connection is unfavorable for repair and replaces.
