For the limit damping of gear switch, position limiting slide block is not easy to wear with compressed spring, long service life, damps easy to adjust.
Specific technical solution:
A kind of rotary switch is in the equipment of electric-controlled parts such as the mechanical, electrical oven of air conditioning window, passing through rotary shaft band moving cam
Mechanism, the rotation of cam mechanism drives elastic conductive component (up and down, left and right) to swing, to realize elastic conductive component upper contact
With the separation and disconnection of fixed conducting element upper contact, change cam and conductive element structure to realize that the contact of customer demand is logical
Disconnected sequence, also just meets the connecting and disconnecting of the circuit requirement of client.
It is the cooperation for relying on position-limited wheel and limiting circlip that rotary switch switches all between shelves and shelves under normal circumstances, then is led to
Cross the damping size of the elastic force adjustment rotation of resistance circlip.Conventional rotary switch is all that mode realizes that rotation is opened according to this configuration
Pass reaches specified gear requirement.Since gear damping and circlip material requirements are high, lead to the life cycle of the structure relatively
It is short, damp under normal conditions it is small in the case where circlip amplitude of fluctuation is small, stress is small that the switch life period is extended, damp
Circlip amplitude of fluctuation is big in the case where big, stress reduces the switch life period.Switch damping is caused to be difficult to do with the service life
To suitable adjustment.
By improving structure, the compressed spring of our company conventional criteria part substitutes clip spring structure, to extend switch life
Period, while sliding block boss circular arc size being cooperated to realize that damping is adjustable.
Position-limited wheel: it is identical as original structure, structural adjustment is not done, only needs to change the number of teeth according to client to reach required
The switch position quantity wanted.
Sliding block: this structure substitution limit circlip is molded using the preferable thermoplastic material of self-lubricating effect, passes through limit
The circular arc boss of position sliding block realizes gear conversion with limit gear teeth cooperation, can limit by adjusting the size of limited block circular arc to realize
Position wheel and position limiting slide block wear-out life and limit damping size.
Resistance spring: this structure is the components of standard mature in the market, and the spring-compressed service life is original clip spring structure
Decades of times, spring size, diameter selection depend on switch damping size.
The invention patent changes previous clip spring structure, and the gear of rotary switch is realized by the cooperation of sliding block and spring
Switching, at the same switch life cycle stretch-out, damping is easy to adjust.
