Embodiment
Self-locking rotary switch as Figure 1-Figure 5, includes shell 1, moving contact 2 is equipped with shell 1, several are quiet
Contact 3 and for controlling the shaft 4 switched between moving contact 1 and static contact 3, shaft 4 is fixedly connected with moving contact 2,
Several static contacts 3 are distributed in distance circumferentially around in the periphery of shaft 4, and one end of shaft 4 is rotatably arranged in shell 1 simultaneously
It is slidably matched with shell 1, and is installed with positioning seat 9, several is provided with 1 inner wall of shell and is determined for what positioning seat 9 abutted
Position fin 11, forms the positioning chamber 12 of spacing positioning seat 9 between adjacent positioned fin 11, location fin 11 and 1 bottom surface of shell it
Between there is the passage 13 that passes through for positioning seat 9；Sliding pawl set 5 and spring 6,6 one end housing 1 of spring is cased with outside shaft 4 to abut against,
The other end is connected on sliding pawl set 5；The first turning gear 51 is provided with the outer circumference surface of sliding pawl set 5, the first turning gear 51 is cylindrical
Several are evenly distributed on side face and slides pawl 52, is set with top cover 7 on sliding pawl set 5,7 one end of top cover is correspondingly arranged on can be with first
Turning gear 51 forms the second turning gear 71 being rotatably assorted, and some convex ribs are evenly distributed on the outer circumference surface of the second turning gear 71
72, and convex ribs 72 are formed with the cunning pawl 52 on corresponding sliding pawl set 5 and contacted, and the set on shell 1 is set with outside top cover 7
Shell 8, several sliding slots 81 slipped into for sliding pawl 52 and convex ribs 72 are evenly distributed on the inner peripheral surface of sheath body 8, and sliding slot 81 is in
It is axial to set, a convex block 82 is formed between adjacent sliding slot 81, two inclinations with sliding 52 phase slide lines of pawl are provided with convex block 82
Face 83, two inclined planes 83 form zigzags, i.e., the incline direction of two inclined planes 83 is identical and adjacent on there is difference in height
And form sharp groove 84；Shaft 4 is linked with sliding pawl set 5, top cover 7 along 5 axial direction of shaft.When sliding pawl 52 is in sliding slot 81
It is interior, press shaft 4, shaft 4 and top cover 7 and elapse certain distance toward 1 direction of shell, top cover 7 moves the sliding pawl set 5 of compressing along sliding slot 81
Mobile, convex ribs 72 promote sliding pawl 52 to be skidded off out of sliding slot 81, because the first turning gear 51 and the second turning gear 71 are rotatably assorted, sliding pawl
Set 5 is rotated by radial load, through with being directed to after 83 sliding contact of inclined plane in sharp groove 84, then therefore passage extremely positions positioning seat 9
