Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail.
The present embodiment provides a kind of rotary switch anti-rotation structure, comprise, the driven rotary by switching knob rotates be arranged in switch base 11 changes the cam 33 of conducting state for driving switch, the boss 332 of outstanding shaping annular on the cam 33 vertically, be molded over the gear groove 332a on boss 332 lateral wall, the cell wall of gear groove 332a is inclined-plane, by the gear button 34 that mounting structure arranges limit spring 35 in the enclosure and is resisted against on boss 332 lateral wall by limit spring 35 elastic force effect, gear groove 332a is corresponding trigger end 331 respectively; When switch is in conducting state, gear button 34 lays respectively in corresponding gear groove 332a, and limited spring 35 is resisted against on the lateral wall of boss 332, and is stopped by the cell wall of gear groove 332a and can not deviate from gear groove 332a easily.
When switch is in different conducting states, gear button 34 lays respectively in corresponding gear groove 332a, limited spring 35 is resisted against on the lateral wall of boss 332 under acting on, and stopped by the inclined-plane cell wall of gear groove 332a and gear groove 332a can not be deviate from, now, even if when knob 31 is touched by active force less unintentionally, gear button 34 also can not deviate from gear groove 332a, can only when adopting larger active force rotation process knob, could deviate from from gear groove 332a, thus do not affect switch and switch between different conducting states, and can the stability of maintained switch conducting state, avoid extraneous being not intended to interference and the change of state that causes, ensure switch and be connected to the safety of the electrical equipment on switch.And when reversing switch carries out in handoff procedure between conducting state, gear button 34 is deviate from and is entered in other gear groove 332a from the gear groove 332a at its initial place, when gear button 34 is when near gear groove 332a, gear button 34 slips in gear groove 332a along inclined-plane cell wall, thus can ensure that switch is in conducting state, when gear button 34 enters in other gear groove 332a, switch just completes the conversion of state.
The rotary switch rotation-preventing mechanism of the present embodiment, mounting structure comprises, fixed installation groove 112a inside the upper wall 112 being molded over switch base 11, mount cover and fixedly mounting the limited cover 36 on groove 112a to form the space of fixing limit spring 35 and gear button 34, and make limit spring mounting groove 112a have the notch 112b of opening towards cam 33, limit spring 35 is provided with in fixed installation groove 112a, gear button 34 has the butting section 342 on the matrix part 341 be arranged in fixed installation groove 112a and the lateral wall being directly resisted against boss 332 protruding from fixed installation groove 112a setting, limit spring 35 one end is resisted against on the inwall of switch base 11 sidewall, one end is resisted against the matrix part 341 of gear button 34, all the time apply towards the elastic force effect outside notch 112b to gear button 34 in limit spring 35, gear button 34 and boss 332 is made to keep close contact.
By arranging fixed installation groove 112a in switch base 11, for fixing limit spring 35 and gear button 34 provide installing space, fixing limit spring 35 is made to provide the active force towards cam 33 direction to gear button 34 all the time, and make this active force remain on along in the radial direction of cam 33, gear button 34 and boss 332 is made to keep close contact, thus ensure that cam 33 rotates to switch when being in conducting state, gear button 34 limit spring 35 that can be fixed is pressed in gear groove 332a, ensure that the stability of rotation-preventing mechanism effect.When gear button 34 needs to deviate from from gear groove 332a, cam 33 rotates and applies pressure compression limit spring 35 to gear button 34, and butting section 342 bounces back towards notch 112b direction gradually.
The rotary switch rotation-preventing mechanism of the present embodiment, the width of the notch 112b of fixed installation groove 112a is less than the width of fixed installation groove 112a inside, gear button 34 has width and is greater than the width of notch 112b and is less than the matrix part 341 fixedly mounting groove 112a inner width, and butting section 342 width be molded on matrix part 341 is less than notch 112b.
Butting section 342 width is less than notch 112b can pass notch 112b to make butting section 342, and the width of matrix part 341 is greater than the width of notch 112b, thus gear button 34 can be fixed in fixed installation groove 112a.
The rotary switch rotation-preventing mechanism of the present embodiment, block 113 reduces towards the direction of cam 33 gradually near the width of cam 33 end.To make block 113 top form wedge angle, block 113 is reduced with the contact area of cam 33, reduces the frictional force between block 113 and cam 33.
The rotary switch rotation-preventing mechanism of the present embodiment, the shape of gear groove 332a is identical with the shape of gear button 34 end.
The rotary switch rotation-preventing mechanism of the present embodiment, fixed installation groove 112a forms for limited cover 36 being fixed on the clip 114 fixedly mounted on groove 112a along cell wall vertical direction.Clip 114 makes limited cover 36 be fixed on fixed installation groove 112a, facilitates the dismounting of limited cover 36.
The rotary switch rotation-preventing mechanism of the present embodiment, also comprise the restriction rotational structure preventing cam 33 from excessively rotating, restriction rotational structure comprises, be molded over the boss projection 333 axially of boss 332, be molded over the block 113 on the inwall of the upper bottom surface 112 of switch base 11, boss projection 333 is equal to the distance of switch base 11 axis with block 113 to the distance of cam 33 axis, when cam 33 turns to and is greater than change switch-turn-ON states trigger angle, cannot be rotated further by the stop of block 113.
Boss 332 arranges boss projection 333; the inwall of switch base 11 arranges block 113; boss projection 333 rotates along with cam 33; when cam 33 turn to be greater than change switch-turn-ON states trigger angle time; boss projection 333 will touch block 113; and prevent cam 33 inordinate rotation, the safety of further protection switch.
The rotary switch rotation-preventing mechanism of the present embodiment, block 113 is 4, has the block face vertical with the upper bottom surface 112 of switch base 11, the coplanar setting of block face of two relative blocks 113.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And thus the apparent change of extending out or variation be still among the protection range that the utility model creates.
