Pad turn-over device of pedalled toilet
Technical field: the present invention relates to a kind of foot toilet cushion pad turn-over device.
Background technology: at present, it is moving with handspring to turn over, transfer Shi Junxu on the cushion of the toilet seat of China's overwhelming majority or the title ring, very unhygienic, the toilet seat that uses in the toilet in public particularly also exists the hidden danger of cross infection during disease transmission.At present also the someone invented the toilet seat that turns over pad with electric control up and down, but the user also needs to press the switch that is located at toilet seat body bottom with hand could be stirred up and down, though adopted electronic, but also need stoop the waist hand operated, no basic change on original basis, use still inconvenience is arranged more, have the strike note that cushion and toilet seat seated connection touch when stirring, and also there is following weak point in this technology:
One, toilet seat uses and be unable to do without the water flushing, and environment for use all has the existence of water, and therefore the accident of electric leakage and so on takes place easily, has potential safety hazard;
Two, present energy scarcity adopts electronic mode to increase energy resource consumption, and increases customer charge;
Three, the environment that does not have electricity can not use, and can not normally use during as power failure;
Four, need and the toilet seat global design is made, can not with commercially available common toilet seat adapted.
Summary of the invention: the objective of the invention is the pad turn-over device of pedalled toilet that provides a kind of reliable operation, no electric shock hidden danger in order to solve the weak point that above-mentioned prior art exists, need not working power, this device once just can make the toilet seat cushion roll up fast by foot-operated this under-chassis pedal of user, step on again cushion is turned down, successively circulation; Further purpose of the present invention does not have the bump of cushion and toilet seat seat when providing a kind of stirring and the pad turn-over device of pedalled toilet that knocks.
In order to realize above-mentioned purpose, the present invention adopts following scheme: a kind of pad turn-over device of pedalled toilet, it is characterized in that: described pad turn-over device of pedalled toilet is provided with frame, the moving seesaw-type pedal gear, push rod, turn over pad connector and push rod changement, the described pad connector that turns over is provided with a main shaft, be respectively equipped with the driving collision block in the main shaft both sides, described push rod vertically is provided with, one end of lower end and seesaw is hinged, described push rod changement is made of horizontal reciprocally swinging mechanism, described swing mechanism has two settling positions, described two settling positions make push rod aim at two collision blocks respectively, described swing mechanism commutation and the descending action interlock of push rod; Described swing mechanism comprises swing sheet, reversing plate and elastic torque transmission device, described swing sheet and reversing plate are equipped with rotating shaft, be in triangular distribution on the plane of described swing sheet two touching levers and a pendulum pin vertically are set, rotating shaft is parallel with touching lever and pendulum pin, the end of described pendulum pin is connected with a compression spring, and the compression spring compression back other end is fixed on the frame; Be provided with the elastic torque transfer device between described swing sheet and the reversing plate, described elastic torque transmission device is by a left side that is arranged on the reversing plate outside, right clamping piece and energy-stored spring are formed, a described left side, the right clamping piece middle part is rotatably positioned to be arranged on by the commutation pin and forms interlock on the reversing plate, a left side, the right clamping piece upper end is clipped on the pendulum pin from both sides, a left side, right clamping piece is provided with energy-stored spring between the lower end, reversing plate is provided with guide ring, described push rod upper end penetrates guide ring and constitutes laterally interlock, described push rod is provided with the jacking block of projection, reversing plate is when two settling positions, and jacking block is corresponding with two touching levers of swing on the sheet respectively.
As the further setting of the present invention: described pad turn-over device of pedalled toilet also is provided with one and turns over the pad damping unit, described turning over filled up damping unit and turned over pad connector driving coupling, described turn over the pad damping unit be centrifugal damping unit, the profile of centrifugal damping unit is in the form of annular discs, outer casing inner wall is provided with annular wearing piece, rotating shaft is provided with the centrifugal sheet main wheel that gets rid of, the centrifugal sheet main wheel edge that gets rid of is evenly distributed with the guiding breach, all be provided with movingly in each guiding breach and get rid of the sheet friction block, rotating shaft with turn over pad connector spindle drive and connect, turning over the pad damping unit also can be to be Electromagnetic generation formula damping unit, the rotating shaft of Electromagnetic generation formula damping unit with turn over pad connector spindle drive and connect, the described main shaft that turns over the pad connector is provided with sector gear, centrifugal damping unit rotating shaft is provided with gear, and described sector gear and gears engaged constitute described driving coupling.
Further be provided with as of the present invention: described pad turn-over device of pedalled toilet is provided with the backing plate balanced controls again, described balanced controls are made of the elastic torque damping mechanism that turns over the pad connector, damping force is opposite with the cushion falling force, balanced controls are made of the elastic torque damping mechanism that turns over the pad connector, damping force is opposite with the cushion falling force, the elastic torque damping mechanism can be to be made of the balancing frame and the extension spring that are located on the main shaft of renovating connector, extension spring one end is fixedly connected on the balancing frame circumference, the other end is fixed on the frame, also can constitute by the balancing frame and the torsion spring that are located on the main shaft of renovating connector, described torsion spring set is located on the main shaft, torsion spring one end is fixedly connected on the balancing frame card, and the other end is fixed on the frame.
