Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Please refer to Fig. 1 to Fig. 5.Comprise according to the operator 100 of the rotary switch of the utility model one embodiment: key 1, case ring 2, rotating shaft 3, waterproof grommet 4, shell 5, centring ring 6, cam 7, a pair of driven sliding block 10, driven sliding block resetting device, spike nut 11, rubber ring 12 and the fillet of screw 13.
Key 1 is connected with the upper end of rotating shaft 3.Wherein, the top of rotating shaft 3 is provided with a groove, is provided with a square boss in groove; The bottom surface of key 1 is provided with the square hole suitable with this square boss; Key 1 is inserted in this groove, and the square hole of key 1 is enclosed within this square boss.
Case ring 2 connects with shell 3 spirals.Waterproof grommet 4 is arranged between rotating shaft 3 and the contact-making surface of shell 5, for water proof and dust proof.Centring ring 6 and cam 7 are all set in rotating shaft 3, and can rotate with rotating shaft 3.The surface of centring ring is provided with a boss 61, and boss 61 matches with a stopper slot on shell 5 center bore inner walls, and the rotational angle of rotating shaft 3 is restricted to 120 ° (respectively rotating 60 ° clockwise and counterclockwise).Cam 7 is provided with pair of projections 71, this pair of projections 71 contacts with the helicoid on a pair of driven sliding block 10 tops respectively, when cam clockwise rotates, drive one of them driven sliding block 10 to move down, when cam rotates counterclockwise, drive another driven sliding block 10 to move down.In a specific embodiment, the shape of cross section of rotating shaft 3 is square.
The lower end outer wall of rotating shaft 3 is provided with external screw thread, and spike nut 11 rotation sets are in the lower end of rotating shaft 3, and against cam 7, thereby centring ring 6 and cam 7 are fastened in rotating shaft 3.
The below hole wall of the centre bore of shell 5 is provided with a pair of dovetail groove 52 vertically extending, the outer wall of each driven sliding block 10 is provided with the dovetail projection 102 suitable with dovetail groove 52, and this pair of dovetail groove 52 is set in respectively on the dovetail projection 102 of this pair of driven sliding block correspondingly movably.Due to the swallow-tail form that is shaped as of dovetail projection 102 and dovetail groove 52, move up and down Shi Buhui in driven sliding block 10 and rock, guidance quality is better.
Driven sliding block resetting device comprises extension spring keeper 8 and a pair of extension spring 9, and the upper end of this pair of extension spring 9 is connected with extension spring keeper 8, and the lower end of this pair of extension spring 9 is connected with a pair of driven sliding block 10 respectively correspondingly.In embodiment shown in the figure, extension spring keeper 8 is arranged on spike nut 11.This extension spring keeper 8 is a sliding plate, and sliding plate 8 is enclosed within on spike nut 11 rotationally.Wherein, the outer wall of spike nut 11 is provided with ring-shaped step, and the bottom surface of sliding plate 8 is connected on this ring-shaped step.On sliding plate, be provided with two location holes 81, the top hook 91 of each extension spring 9 is hooked on a location hole 81, and the below hook 92 of each extension spring 9 is hooked on the hook being arranged in driven sliding block 10.
