Specific embodiment
The utility model is further elaborated in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, a kind of external safety switch of knob, including control cabinet 1, limit
Position pull rod 2, control handle 3, spring retainer bar 4, insulating bar 5, knob slot 6, rotating handle 7, the convex touching of newel 8, sliding slot 9, rotating ring
10, newel 11, external convex touching 12, convex annular touching 13,1 integrated injection forming of control cabinet have knob slot 6, and control handle 3 connects
Insulating bar 5 is connect, insulating bar 5 is welded to connect rotating handle 7, connection installation spring retainer bar 4, spring retainer bar 4 on 2 body of rod of limit pull rod
The body of rod is mounted on insulating bar 5, external convex integrally formed with the convex touching 8 of newel and sliding slot 9, rotating ring 10 on newel 11
Touching 12,13 welding of convex annular touching are mounted on 7 end of rotating handle.
The fixing groove 14 being correspondingly arranged with convex annular touching 13, two fixing grooves are installed built in the knob slot 6 of the control cabinet 1
It is connected between 14 by metal bar 15, the convex touching 16 of rotation is installed by welding at 7 body of rod of other side rotating handle.
The rotating handle 7 uses the sealing installation of sealing cover 17.
2 center of limit pull rod is equipped with guide rod 18.
7 heartcut of rotating handle forms limiting slot 19, and limiting slot 19 is correspondingly arranged with spring retainer bar 4, can control
The rotation of rotating handle 7 processed.
Utility model works principle: a kind of external safety switch of knob, this is suitable for power domain in device design
