In order to make the rotary switch operator can water proof and dust proof, the end face of supporting portion 931 be provided with the annular groove 933 around center hole 932, is provided with waterproof ring 97 in annular groove.This waterproof ring is the strength member that affects rotary switch operator security level.What existing rotary switch operator adopted mostly is O type waterproof ring, and as shown in Figures 2 and 3, this makes rotating shaft 92 can be subject to larger frictional force when rotating, thereby impact rotation feel even affects the normal reset of driven sliding block 95.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of easily deformable waterproof ring.
Another technical problem to be solved in the utility model is to provide a kind of rotary switch operator that adopts above-mentioned waterproof ring.
For solving the problems of the technologies described above, the utility model provides a kind of waterproof ring, it comprises main part and the upwardly extending lug boss of upper angled of this main part certainly, lug boss has ramp and lower inclined plane, this ramp and lower inclined plane intersect at the top of lug boss, wherein, the angle β between the angle theta between ramp and lower inclined plane and lower inclined plane and main part upper surface is acute angle.
The utility model also provides a kind of rotary switch operator, it comprises swing handle, the rotating shaft and the housing that connect and can rotate with swing handle with this swing handle, rotating shaft comprise base portion and certainly the bottom surface of this base portion to the axle body portion of downward-extension, the top of housing is provided with the supporting portion relative with the bottom surface of base portion, base portion is pressed on the end face of this supporting portion, the end face of this supporting portion is provided with the center hole that the described axle body of confession portion is passed, the end face of supporting portion is provided with the annular groove around this center hole, in this annular groove, is provided with waterproof ring; Its feature is, waterproof ring comprises main part and the upwardly extending lug boss of upper angled of this main part certainly, lug boss has ramp and lower inclined plane, this ramp and lower inclined plane intersect at the top of lug boss, wherein, the angle β between the angle theta between ramp and lower inclined plane and lower inclined plane and main part upper surface is acute angle; The top of the lug boss of the bottom surface butt waterproof ring of rotating shaft base portion.
Between the lug boss of the utility model waterproof ring and main part, there is deformation space, the lug boss of waterproof ring is easy to distortion when being subject to external compression, thereby in the situation that do not change the material of waterproof ring and the product structure of rotary switch operator, do not increase manufacture cost, greatly reduce the frictional force between waterproof ring and the rotating shaft of rotary switch operator, make the rotation feel of rotary switch operator itself not dull, and improved the water proof and dust proof effect of rotary switch operator.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
The structure of rotary switch operator of the present utility model as shown in Figure 4, comprises swing handle 11, rotating shaft 12, the housing 13 that also can rotate with swing handle 11 with these swing handle 11 connections, is arranged on cam 14, driven sliding block 15 and Returnning spring 16 in rotating shaft 12.Rotating shaft 12 comprise base portion 121 and certainly the bottom surface of this base portion 121 to the axle body portion 122 of downward-extension, the top of housing 13 is provided with the supporting portion 131 relative with the bottom surface of base portion 121, the end face of supporting portion 131 is provided with a center hole 132 passing for axle body portion 122 and around the annular groove 133 of center hole, is provided with waterproof ring 17 in annular groove 133.
The structure of waterproof ring 17 as shown in Figure 5 and Figure 6, it comprises main part 171 and the upwardly extending lug boss 175 of upper angled of this main part 171 certainly, lug boss 175 has ramp 176 and lower inclined plane 178, this ramp 176 and lower inclined plane 178 intersect at the top of lug boss 175, wherein, angle theta between ramp 176 and lower inclined plane 178 is acute angle, and preferably, 45 ° of 10 ° of < θ <; Angle β between lower inclined plane 178 and main part upper surface 172 is acute angle, and preferably, 60 ° of 15 ° of < β <; The top projection of lug boss 175 drops on the surface area of main part 171.
The base portion 121 of rotating shaft 12 is pressed on the end face of this supporting portion 131, the top of the lug boss 175 of the bottom surface butt waterproof ring of rotating shaft base portion 121.Owing to having deformation space between the lug boss 175 of waterproof ring and main part 171, the lug boss 175 of waterproof ring is easy to distortion when being subject to base portion 121 extruding.Therefore,, when swing handle 11 drives rotating shaft 12 to rotate, the frictional force between waterproof ring 17 and rotating shaft 12 is less, makes the rotation feel of rotary switch operator itself not dull, has improved user's experience.
The utility model compared with prior art, in the situation that do not change the material of waterproof ring and the product structure of knob, do not increase manufacture cost, only, by changing the shape of waterproof ring, realized the improvement that user experiences, and the water proof and dust proof ability of rotary switch operator is improved.
