Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Embodiment 1
A kind of manual-operating mechanism of double acting pneumatic actuator, the manual-operating mechanism is by the screw mandrel 2 of protective cover 1, cover plate
3rd, first end face bearing 4, second end face bearing 5, anti-bull stick 6, support 7, connecting rod 8, handwheel disk 9 and feed screw nut 10, anti-rotation
Screw 11 and protective plate 12, the grade of tie down screw 13 critical piece composition, support 7 are connected with cover plate 3, and feed screw nut 10 is positioned at branch
The inside that frame 7 surrounds with cover plate 3, is equipped with the second end between feed screw nut 10 and support 7 and between feed screw nut 10 and cover plate 3
Spherical bearing 5 and first end face bearing 4, it is possible to reduce when screw mandrel 2 moves forward and backward, feed screw nut 10 and support 7, cover plate 3 it
Between frictional force, feed screw nut 10 is connected with handwheel disk 9, has tie down screw 13 between handwheel disk 9 and cover plate 3, work as aerodynamic condition
Under, the tie down screw 13 is in locking state, avoids handwheel disk 9 because vibration or maloperation cause to rotate, the portion that screw mandrel 2 exposes
Point covered with protective cover 1, there is projection 201 end of screw mandrel 2, there is circular hole 202 in projection 201, anti-bull stick 6 through projection 201 and
The first guide groove 701 and the second guide groove 702 of support 7, the end of anti-bull stick 6 are connected with nut, and connecting rod 8 connects with actuator
