Even, the base of described ratch mechanism is connected with the lower end in telescoping support portion.
By technique scheme, described ratch mechanism is two groups, all includes base, is provided with tooth bar, in base in base
Inside it is additionally provided with that cross bar is parallel with tooth bar, be respectively arranged at two ends with arc-shaped slide rail in the corresponding tooth bar of base intracavity, corresponding on tooth bar
It is configured with ratchet, a ratchet of every group of ratch mechanism is connected with a connecting rod respectively, two connecting rods are in arranged crosswise, two connecting rods
Upper end is hinged with the two ends of seat board respectively, connecting rod, ratch mechanism, arc-shaped slide rail, cross bar, is formed and is easy to the reciprocal of lift adjustment
Mechanism.
By technique scheme, it is in the telescopic sleeve mechanism that diagonally opposing corner is arranged that described adjustable supporting part includes two
With two be in diagonally opposing corner arrangement the telescopic outer pipe mechanism locking, described telescopic sleeve mechanism include upper bush and under
Sleeve, lower sleeve and lower sleeve be mutually socketed and can sliding to axial, described upper bush and seat board are fixedly connected with；Described lock
Telescopic outer pipe mechanism include upper support and lower support, outer pipe, the upper end of upper support and seat board are fixedly connected with, lower end inner sleeve
In outer pipe, and it is connected with outer pipe by eccentric locking mechanism；It is placed in cylindrical pipe in the upper end of described lower support, and with
Outer pipe is fixedly connected with.
By technique scheme, fixed by latch or bolt between described upper bush and lower sleeve.
By technique scheme, described eccentric locking mechanism includes the eccentric orfice arranging in outer pipe and outside upper support
The elastic bumps of wall setting, described elastic bumps and eccentric orfice phase configuration.
By technique scheme, it is also associated with the backrest with angle of inclination on the top of seat board.
Having the beneficial effect that acquired by the present invention：The present invention can carry out self-control according to the difference of child height,
The growth period of children can save purchase cost with Long-Time Service, and easy to operate simple, and stability is good.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, present embodiments providing a kind of self adaptation children's seat, including seat board 2, lean on above seat board 2
Place is fixed with the backrest 1 with angle of inclination afterwards, is formed around adjustable supporting part in the lower section of seat board 2, under seat board 2
Side is provided with two groups of one-way ratchet mechanism interfaced, and every group of ratch mechanism all includes base 11, be provided with tooth bar 12 in base 11, in base 11
Inside it is additionally provided with that cross bar 14 is parallel with tooth bar 12, cross bar 14 is located at the oblique upper of tooth bar 12, the two of the corresponding tooth bar of base 11 inner chamber
End is respectively equipped with arc-shaped slide rail 13, and on tooth bar 12, correspondence is configured with ratchet, and a ratchet of every group of ratch mechanism is respectively with one
Individual connecting rod 10 is connected, and two connecting rods 10 are in arranged crosswise, and the upper end of two connecting rods 10 is hinged with the two ends of seat board 2 respectively, connecting rod, spine
Gear mechanism, arc-shaped slide rail, cross bar, form the reciprocator being easy to lift adjustment.Two groups of bases are installed in by front and back's crossbeam 8 and a left side
In right crossbeam 6 enclosed space.
It is in diagonally opposing corner that described adjustable supporting part includes the telescopic sleeve mechanism of two arrangements in diagonally opposing corner and two
The telescopic outer pipe mechanism locking of arrangement, described telescopic sleeve mechanism includes upper bush 3 and lower sleeve 4, described on
Sleeve 3 is fixedly connected with seat board 2, lower sleeve 3 and lower sleeve 4 be mutually socketed and can sliding to axial, both can be selected to pass through
Latch or bolt are spacing.As shown in Fig. 2 the described telescopic outer pipe mechanism locking include supporting 15, lower support 7, outer
Pipe 5, the upper upper end supporting 15 is fixedly connected with seat board 2, is placed in cylindrical pipe 5 in lower end, and by eccentric locking mechanism with outward
Pipe 5 is connected；Described lower support in 7 upper end is placed in cylindrical pipe 5, and is connected with outer pipe, wherein, lower support can with outer
Pipe is fixedly connected with can also be by eccentric locking mechanism and outer pipe configuration, depending on actual design.
Described eccentric locking mechanism includes the eccentric orfice of setting in outer pipe 5, is all correspondingly provided with bullet in upper support on 15
Property projection 16, when supporting 15 in rotation, after making elastic bumps 15 screw in eccentric orfice, upper support can outer pipe 5 axially be slided relatively
Moving, thus realizing adjusting the purpose of height, after reaching intended height, then making elastic bumps 16 screw out eccentric orfice, you can locking
Upper support and outer pipe.
When needing to adjust height of seat, by operating eccentric locking mechanism and extracting latch or bolt out, make upper and lower sleeve
Between, upper support is in slip state between 15 and outer pipe 5, is lifted up seat board 2, and the connecting rod 10 driving lower section is in ratchet
One-way movement in mechanism, when reaching suitable height, because the one-way of ratchet can make seat board will not glide, is determining
After the proper height of seat board, by tightening eccentric locking mechanism, can be fixing by the upper support 15 below seat board, pass through simultaneously
Latch or bolt are spacing, so that upper and lower sleeve is relatively fixed, and so that seat board will not upper be in use moved.When the height needing reduction seat
When spending, make each connecting rod 10 one-way movement fall into Fig. 4, the arc-shaped slide rail 13 shown in 5 to after extreme position, then manually grasp
Make, so that the lower end of connecting rod 10 is fallen on cross bar 14, and slide onto with cross bar 14 and readjust the height of seat board 2 after the other end again and be
Can.
