Specific embodiment
With reference to specific embodiment, the technical scheme of this patent is described in more detail.
Refer to Fig. 1-4, a kind of stair integrating safety and interest, including loft grillage 1, installing rack 2 and
Pedal 3, described installing rack 2 is provided with two and is respectively fixedly connected with loft grillage 1 upper end both sides, and described pedal 3 is provided with multiple
And be uniformly connected to up and down in the middle of installing rack 2, described pedal 3 is single shaft and rotates with installing rack 2 and is connected, the pedal 3 of bottom
It is fixedly connected with support base 4 on the right side of lower end and the fixation of pedal 3 upper end is sticked and has cushion pad 5, carry out certain bumper and absorbing shock, remaining
Pedal 3 lower end all offers chute 6, slidably connects slide block 7 in chute 6, slide block 7 lower end all with hand-operated spiral lifter 8
Telescopic head rotates and connects, and is rotated by hand-operated spiral lifter 8 controllable pedal 3 that stretches, the stretching of hand-operated spiral lifter 8
Indention journey should ensure that pedal 3 is horizontality in its maximum development length, and all pedals 3 should in its maximum collapse length
Form smooth clinoplain；Described hand-operated spiral lifter 8 is fixedly connected with fixed mount 9, and fixed mount 9 tilts fixing company
It is connected in loft grillage 1, the hand axle of hand-operated spiral lifter 8 has been fixedly connected with worm gear 10, in described loft grillage 1 also
It is fixedly connected with two mounting seats 11, between mounting seat 11, is rotatably connected to power transmission shaft 12, if fixation is arranged with power transmission shaft 12
The dry worm screw 13 being connected with worm gear 10 engagement, power transmission shaft 12 top is also fixedly connected with travelling gear 14, in left side mounting seat 11
Also be fixedly connected with either-rotation motor 15, the rotary shaft of either-rotation motor 15 be fixedly connected with driving gear 16, driving gear 16 with
Travelling gear 14 engagement connects, and is rotated by the hand axle that either-rotation motor 15 rotational band starts to shake helical riser 8 and completes it and stretch
Contracting, driving gear 16 wheel footpath is more than travelling gear 14 wheel footpath, lifts the flexible speed of hand-operated spiral lifter 8 by increasing gear ratio
Degree, rapidly pedal 3 flop transition can be mitigated injuring of being subject to of human body for burnishing surface in human body fall, because of gear ratio increase
Simultaneously bi-directionally motor 15 drives multiple loads, and the torque power of either-rotation motor 15 selects to add in the case that space allows as far as possible
Greatly；Described pedal 3 both sides all offer work in coordination agree with groove 17, agreeing with when pedal 3 overturns between groove 17 can contract mutually
Close lifting surface smoothness and can support mutually improving stability, along its long side to uniformly offering some peaces inside pedal 3 simultaneously
Dress hole 18, installing hole 18 inner bottom part has been fixedly connected with rubber bearing 19, has been equipped with shaking sensor 20 in installing hole 18, peace
All it is threaded with cover plate 21, cover plate 21 should excessively coordinate, and should ensure that when cover plate 21 is tightened and can squeeze at the aperture in dress hole 18
It is pressed onto rubber bearing 19 and deform it is ensured that being delivered on shaking sensor 20 of completing of shock energy that pedal 3 surface is born, vibrations
The working value of sensor 20 should be adjusted in desired value it is ensured that the vibrations when human normal is walked will not trigger shaking sensor 20
Action, and the vibrations larger in human body fall then can smoothly make shaking sensor 20 action, this must for the normal operation of system
Standby condition, all offers a word edge of a knife 22 at transmission cover plate 21 upper end center, and being opened and closed cover plate 21 by flat mouth screwdriver can facilitate
The shaking sensor 20 damaging is changed；Also it is fixedly connected with controller 23, controller 23 adopts in described loft grillage 1
S7-200 Programmable Logic Controller 23, conveniently needs to carry out real-time programming adjustment, institute more flexible compared with Single-chip Controlling according to user
State shaking sensor 20 be all electrically connected with the input of controller 23 because shaking sensor 20 quantity more, Programmable Logic Controller
23 can add expansion module, and the outfan of controller 23 is electrically connected with either-rotation motor 15, by the detection of shaking sensor 20
The unlatching of action control either-rotation motor 15, controller 23 input is also electrically connected with rotating forward switch and reversal switch, just turns on
Close and reversal switch is all drawn outside loft grillage 1, can easily pass through its upset of two on-off control when child needs to play
Thus switching rapidly between stair and slide, what shaking sensor 20 was controlled is the slide flow process of pedal 3, extensive as it
Become stair can control by above-mentioned reversal switch again, also can program to realize with timing reversion by controller 23, according to reality
Border situation is selected, and the power supply supply of above-mentioned electrical part directly can install socket in loft grillage 1, it is to avoid circuit exposes shadow
Sound is attractive in appearance, can open up loft door to carry out certain utilization to its inner space, be also convenient for overhauling simultaneously on the left of loft grillage 1.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment party
Formula, in the ken that one skilled in the relevant art possesses, can also be on the premise of without departing from this patent objective
Make a variety of changes.
