As shown in Figure 1, a kind of with foot-operated child learning desk, including desk body and footstep mechanism.Desk body includes desktop block 1
With two stands 2.The both ends of 1 bottom surface of desktop block are fixed respectively with the top of two stands 2.It is respectively provided in two stands 2 free
Chamber, and the bottom of two 2 opposite side sides of stand is provided with foot-operated notch.
As shown in Fig. 1,2,3,4 and 5, footstep mechanism includes foot pedal 3, pedal stand 4, optical axis 5 is turned up, bolt 6 is turned up, is sliding
Dynamic seat 7, sliding square shaft 8, compressed spring 9, gas spring 10, clutch optical axis 11, separation button 12, locking rack gear 13 and locking tooth block
14.The surface of pedal stand 4 is arranged in foot pedal 3.Bolt 6 is turned up and uses outer-hexagonal bolt.It is turned up fixed on the head of bolt 6
There is spill spin block.The both ends of two spill spin blocks being turned up on bolt 6 and 3 bottom surface of foot pedal respectively constitute height-regulating revolute pair.Two tune
The axis collinear of the common axis of high revolute pair and corresponding height-regulating bolt 6.The two sides of 3 bottom surface of foot pedal and two height-regulating optical axises 5
Top fix.Two threaded holes opened up on bolt 6 and pedal stand 4 are turned up for two and respectively constitute screw pair.Two height-regulating light
Axis 5 constitutes sliding pair with pedal stand 4.
The piston rod for sliding square shaft 8, one end of locking rack gear 13 and gas spring 10 is fixed with pedal stand 4.Slide square shaft 8
Sliding pair is constituted with sliding seat 7.Locking rack gear 13 is made of integrally formed locking item and n the first locking tooths, n >=5.N
Along the axis direction of locking item, successively equidistant arrangement is arranged first locking tooth.The spacing of two neighboring first locking tooth is equal to first
The width of locking tooth.The cross-sectional profiles of first locking tooth include two the first vertical edges and two the first bevel edges.Two mutually equal
The inner end of the first capable vertical edge is connect with locking item, and outer end and one end of two the first bevel edges are separately connected.Two first tiltedly
The other end on side links together.The tie point of two the first bevel edges is on the symmetry axis of two the first vertical edges.Two first tiltedly
The tie point on side and the spacing of locking item are greater than the spacing of the first vertical edge outer end endpoint and locking item.
Locking tooth block 14 is made of integrally formed fixed block and the second locking tooth.The cross-sectional profiles packet of second locking tooth
Include two the second vertical edges and two the second bevel edges.Two the second vertical edge spacing are equal to the spacing of two neighboring first locking tooth.Mutually
The inner end of two parallel the second vertical edges is connect with fixed block, and outer end and one end of two the second bevel edges are separately connected.Two
The other end of the second bevel edge of item links together.The tie point of two the second bevel edges is on the symmetry axis of two the second vertical edges.Two
The tie point of the second bevel edge of item and the spacing of locking item are greater than the spacing of the second vertical edge outer end endpoint and locking item.Second locking tooth
It is against on locking rack gear 13, i.e. the second locking tooth is located therein between two adjacent first locking tooths.Fixed block and four from
One end of light combination axis 11 is fixed.The other end of four clutch optical axises 11 with to separate button 12 fixed.
There are two footstep mechanism is total.Two footstep mechanisms are separately positioned on the cavity bottom of two stands 2.Two treading devices
Sliding seat 7 and the bottom plate of two stands 2 in structure are fixed respectively.The shell of gas spring 10 and two stands in two footstep mechanisms
2 bottom plate is fixed respectively.Clutch optical axis 11 and two stands 2 in two footstep mechanisms respectively constitute glide direction perpendicular to lock
The only sliding pair of axis direction.Compressed spring 9 is cased on the side of all clutch optical axises 11.Compressed spring 9 is arranged right
It should separate between button 12 and stand 2.
The working principle of the utility model is as follows:
Under original state, it is two adjacent that the elastic force of compressed spring 9 is against the second locking tooth in locking tooth block 14
Between first locking tooth, thus locking footstep mechanism.At this point, two pedal stands 4 are located in two stands 2, and gas spring
10 are in compressive state.
When children use the utility model, discovery chair is excessively high, when sole can not land, only need to inwardly squeeze two points
From button 12, that is, locking tooth block 14 may make to separate with locking rack gear 13, two pedal stands 4 are respectively under the promotion of gas spring 10
Pop-up outward decontrols separation button 12 when the spacing of two pedal stands 4 reaches double-legged spacing when children sit up straight, so that lock
Only the second locking tooth in tooth block 14 is against again between two adjacent first locking tooths.Since the speed of gas spring 10 is slow and
Dynamic force change is small, therefore the spacing control of two pedal stands 4 is relatively simple.Due to the outer end of the first locking tooth and the second locking tooth
It is triangular in shape, therefore the first locking tooth can reach with the second locking tooth at any relative position under the promotion of gas spring 10
Stable lock position.
After two pedal stands 4 pop up, while rotating two height-regulating bolts 6 on a pedal stand 4.Since bolt 6 is turned up
Revolute pair is constituted with foot pedal 3, therefore turn is turned up bolt 6 and can rise or reduce the height of foot pedal 3, and then meets different youngsters
Virgin foot-operated demand.
If not needing inwardly to squeeze separation button 12, and pedal stand 4 is pushed into corresponding stand 2 simultaneously using foot pedal 3
Unclamp separation button 12.
