Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
Such as Fig. 1 in conjunction with Fig. 2～shown in Figure 5, a kind of fast-type hand-operated pneumatic COMM communication, comprise protecting cover 1, handwheel 2, connecting rod 3, indicating arm 4 and power lever 5, power lever 5 connects cylinder 6, protecting cover 1 connects handwheel 2, handwheel 2 connects connecting rod 3, connecting rod 3 connects indicating arm 4, it is characterized in that: be provided with between connecting rod 3 and the power lever 5 and switch coupling 7, switch coupling 7 and comprise kink cylinder 8, steel ball 9 and spring 10, the upper end of power lever 5 is the underpart that tubulose also can hold connecting rod 3, the upper end sidewall of power lever 5 is provided with through hole 11, steel ball 9 is positioned at through hole 11, kink cylinder 8 is enclosed within power lever 5 outer also energy, and it endwisely slips relatively, spring 10 is between kink cylinder 8 and power lever 5, and the outer wall of connecting rod 3 is provided with the circular groove 12 corresponding with through hole 11, and steel ball 9 has the primary importance of blocking mutually with connecting rod 3 and and the second place that breaks away from of connecting rod 3.
Be fixed with ball nut 13 on the described handwheel 2, ball nut 13 is installed on the support 16 by positioning gland 14 and needle bearing 15, and ball nut 13 connects connecting rod 3.
Described handwheel 2 connects ball nut 13 by flat key 17.
Through hole 11 on the described power lever 5 is the little conical bore in large inboard, the outside, and the inside diameter of through hole 11 is less than the diameter of steel ball 9, and the outside diameter of through hole 11 is greater than the diameter of steel ball 9; The length of through hole 11 is less than the diameter of steel ball 9.This structure can make steel ball 9 be stuck on the connecting rod 3, and simultaneously, steel ball 9 can not drop out from through hole 11.
The center hole of described kink cylinder 8 is up big and down small reducing hole, is Spielpassung between path section wherein and the power lever 5, and large footpath section wherein and the semidiameter between the path section are less than the diameter of steel ball 9; Pass through the conical bore transition between large footpath section and the path section.Avoid steel ball 9 between kink cylinder 8 and power lever 5, to be pushed out.
