Specific embodiment

A kind of Electric Actuator embodiment of the utility model is described further referring to figs. 1 to Fig. 4.

A kind of Electric Actuator including housing 1, is vertically arranged with output shaft 2 in housing 1, handwheel is equipped on output shaft 2 Component 3, the hand wheel component 3 include handwheel 30 and worm screw 31, the sleeve 32 being slidably matched with it are arranged on the worm screw 31, The axle sleeve of handwheel 30 is fixed with 32 phase of sleeve, and protrusion 320 is set on sleeve 32, and protrusion 320 is arranged with screw hole 321, worm screw 31 Attachment screw 310 is equipped on axle sleeve, attachment screw 310 is worn to the screw hole 321 of protrusion 320, and the handwheel 30 includes wheel Hub 300 and wheel rim 301, the outside of the wheel hub 300 are equipped with several spokes 302, and the spoke 302 is connected with wheel rim 301, phase Wheel rim 301 between two adjacent spokes 302 is equipped with strip arc groove 303, and convex ribs 304, convex ribs are equipped in the arc groove 303 304 part is extended to outside arc groove 303, and spring 305, arc groove are equipped between the bottom wall of convex ribs 304 and arc groove 303 303 inner wall is equipped with flange 306, and convex ribs 304 are equipped with bulge loop 307, the bulge loop with the inconsistent outer surface of flange 306 307 is inconsistent with flange 306, and the groove 308 for supplying to accommodate operator's finger is additionally provided on the wheel rim 301, groove 308 Quantity is four.Rubber layer is equipped in the groove 308, the rubber layer is equipped with several raised 320 particles, described recessed The two side of 308 opening of slot is equipped with rubber convex block 309, and 309 circular in cross-section of rubber convex block is set.The wheel hub 300th, spoke 302 and 301 surface of wheel rim, which apply, is useful for preventing the protective paint to get rusty.

Electric Actuator is operated by hand wheel component 3, and wheel rim 301 and convex ribs 304 can be held in by the hand of operator The palm of the hand, when firmly grasping wheel rim 301 due to hand, the active force between the convex ribs 304 of the palm of the hand and close 300 side of wheel hub is larger, after stress, It can be moved towards the bottom wall direction of arc groove 303, bulge loop 307 and 306 phase friction contradiction of flange on convex ribs 304 so that bulge loop 307 are moved to the lower section of flange 306, and spring 305 is in contraction state.Flange 306 plays the role of temporary /V to convex ribs 304, Slowing down the pressure that convex ribs 304 are subject to, convex ribs 304 are gentle for cambered surface surface, while add the contact area of hand and wheel rim 301, Comfort level can be promoted, is not likely to produce feeling of pain.When hand holds wheel rim 301, four fingers just in four grooves 308, The rubber convex block 309 of 308 opening of groove can play the role of temporary /V finger position, prevent from surprisingly shaking off groove 308, the rubber layer with particle is covered on 308 wall of groove, the frictional force with finger can be increased, and with the work of massage With.When so rotating, it can be very good to prevent to generate slip between hand and wheel rim 301.Comfort level can not only be increased, but also The accuracy that can also cause operation is high, can be with ongoing operation, and service life is long.

The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to Above-described embodiment, all technical solutions belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to Go out, for those skilled in the art, several improvement under the premise of the utility model principle is not departed from and Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
