In the present embodiment, for increasing the intensity of upper drive rod and lower drive rod, be also provided with the enhancing bar 635 for connecting upper drive rod and lower drive rod.From the side, the basic configuration that Manual press pedestal, upper drive rod, lower drive rod and enhancing bar are combined to form is rectangle.
Be inserted in corresponding two pivoted holes to make the convex axle of pivot joint on each Manual press actuator to be easy to, each pivot joint boss, at its close side being combined to form another pivot joint boss of articulated section with it, is also provided with two convex tendons 435 for the formation of guide chute 434.During installation, first convex axle of pivot joint of each Manual press actuator first directly inserts in an adaptive pivoted hole, be connected on corresponding anticreep catch, then firmly the convex axle of pivot joint is moved along the axis pressure of the convex axle of pivot joint, also the convex axle of pivot joint having inserted pivoted hole is namely allowed to extrude anticreep catch, anticreep catch is made to produce certain deformation, thus make the convex axle of another pivot joint can slide in another pivoted hole along wire chute, under the back stretch effect of the anticreep catch of above-mentioned generation deformation, two convex axles of pivot joint can in two pivoted holes between two anticreep catch, and can not therefrom split away off, thus this manual actuation part is rotatably installed on two daggers of front stall.
In the present embodiment, in order to strengthen sensitivity level, the end, rear end of upper drive rod is provided with cylinder 636, the end, rear end of lower drive rod is provided with lower cylinder 637, left and right is extended all in the horizontal direction for each upper cylinder and lower cylinder, makes drive rod and lower drive rod all form linear contact lay with seesaw button separately.In the present embodiment, in the reciprocal shake of seesaw button, upper cylinder is connected to the top of seesaw button all the time, and lower cylinder is connected to the bottom of seesaw button all the time.
See shown in Figure 32, the upper and lower of each Manual press pedestal 631 pedestal is respectively provided with the clamping jack 6311 that runs through pedestal along the longitudinal direction; Fore-and-aft direction described in the present embodiment is front with front stall present position, after tailstock present position is.
See shown in Figure 31, the rear wall of each Manual press panel 62 is provided with two clamping inserting columns 621 protruded backward, a clamping jack on each clamping inserting column and Manual press pedestal is adaptive, each clamping inserting column is plugged in a corresponding clamping jack, thus each Manual press panel is connected and fixed be arranged on a corresponding Manual press pedestal, make both be combined to form Manual press seesaw described in one.
In the present embodiment, in order to better connect Manual press panel and Manual press pedestal; Each clamping inserting column 621 comprises the upper attached column 6211 that protrusion length is shorter backward and the lower attached column 6212 that protrusion length is longer backward, and the periphery wall of each lower attached column rear end is provided with the interference clamping platform 6213 of evagination, is provided with deformation groove 6214 between upper attached column and lower attached column.The shape of the longitudinal cross-section of interference clamping platform is isosceles trapezoid, and also namely it is all provided with guiding surface 6215 in rear and front end, thus makes it be easy to plug.
In the present embodiment each clamping jack of each Manual press pedestal inwall on, be evenly provided with eight semi-cylindrical interference clip-connecting rods 6312; Each interference clip-connecting rod is when inserting in a corresponding clamping jack, first descend the interference clamping platform on attached column because of be subject to interference clip-connecting rod inside squeezing action under, and due to the existence of deformation groove, make lower attached column, towards the direction close to upper attached column, deformation occur, make the lower attached column with interference clip-connecting rod can insert clamping jack; When interference clip-connecting rod is through after clamping jack, end face and the interference clip-connecting rod of upper attached column rear end clamp the pedestal of two side ends before and after clamping jack from rear and front end, thus this Manual press panel is fixed on a corresponding Manual press pedestal.
In the present embodiment, each driving connecting lever is arranged in the Manual press pedestal of a corresponding Manual press seesaw, upper drive rod, lower drive rod and strengthens the space that bar encloses formation, and drive connecting lever in the process along with output shaft reciprocating rotation, all the time be connected to by connecting lever on it and lower connecting lever and strengthen on bar, thus drive corresponding Manual press seesaw back and forth to shake.In the present embodiment, the rear end of upper connecting lever is for being connected to the top strengthening bar, and the rear end of lower connecting lever is for being connected to the bottom strengthening bar.
The remote electric operation element process of the present embodiment is: after in the intelligence in front stall, control circuit module receives circuit conversion order, motor drives a corresponding Manual press seesaw back and forth to shake by driving connecting lever, thus drives a corresponding seesaw button back and forth to shake.
Described Manual press seesaw and driving connecting lever are interlocks, and a rotation, will synchronously drive another also to rotate thereupon between the two; Carry out smoothly in order to manual operation can be made, the reducing gear that after preferred employing power-off, rotary resistance is less, or on the output shaft of motor, increase clutch, the rotation of electric motor circuit breaking rear output shaft is made no longer to be subject to the obstruction of reducing gear, all effective and feasible, these mechanisms are common practise of those skilled in the art, therefore describe in detail no longer one by one at this.
The present embodiment has positive effect: the comparatively compact simplification of (1) the present embodiment structure, manufacturing cost is comparatively cheap, can meet the automatic switchover of two-supply circuit in most cases.(2) the present embodiment can replace conventional wall wall type power switch to use, the automatic switchover or the remote control that realize two-supply circuit switch, thus realize the intellectuality manipulation of household electric appliances and stable Energy control, be particularly useful for changing existing important department electric circuit.
Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And these belong to connotation of the present invention the apparent change of extending out or variation still belong to protection scope of the present invention.
