[specific embodiment]

Consult Fig. 1,2, the preferred embodiment of the utility model perambulator comprises: a skeleton 1, a connecting base 2, be wheel unit 5 before shock absorber 3, the axial buffer device 4 and radially, current wheel unit 5 is subjected to one up during application force 6, this strand application force 6 can be divided into an axial component 61 and a radial component 62 that is perpendicular to one another, and this radially shock absorber 3 be used for absorbing radial component 62, axial buffer device 4 is used for absorbing axial component 61.

This skeleton 1 has the cooresponding antero-lateral rod 11, in two left and right sides and is engaged on the grab rail 12 on two antero-lateral rods, 11 tops, about two the corresponding postero lateral arms 13 that are articulated in two antero-lateral rods, 11 rears, and is erected at the rear wheel unit 14 between two postero lateral arms, 13 bottoms.Wherein these antero-lateral rods 11 all have one in the bottom and toward the central articulated section 111 that bends.

Consult Fig. 3,4, this connecting base 2 is 111 of articulated sections of transverse strands two antero-lateral rods 11 that are located at skeleton 1, above-mentioned connecting base 2 have one across the bridge formation portion 21 of 11 of two antero-lateral rods, the holding part that certainly should bridge formation portion 21 left and right sides down extends 22, two tiltedly stretch from these holding part 22 left and right sides and for the installation portion 23 of articulated section 111 combinations of homonymy antero-lateral rod 11, and four adjacent in twos and about accordingly from the first up outstanding pivot sheet 24 of bridge formation portion 21.Wherein these holding parts 22 comprise forward circular front side wall 221, the surrounding wall 222 that backward extends of these front side wall 221 peripheries certainly, and one by this front side wall 221 with surrounding wall 222 defines and opening spring room 223 backwards, outstanding two front and back downwards out of the ordinary are to parallel spacing prominent bar 224 in each surrounding wall 222 bottom, two 224 of spacing prominent bars on the same surrounding wall 222 define a downward opening limit channels 225, have an outstanding block 226 downwards at two spacing prominent bars, 224 rears.

But this radially shock absorber 3 be to be pivot pendulum mode and connecting base 2 articulates, above-mentioned radially shock absorber 3 has a buffing pad 31, the cooresponding pivot 32 in two left and right sides, the cooresponding radial spring 33 in two left and right sides, and the upright locating dowel pin 34 of correspondence about two, wherein this buffing pad 31 has the shaft sleeve part 311 of two hollow cylindricals, one is engaged on the portion in succession 312 of 311 of two shaft sleeve part, and two second pivot sheets 313 that distinctly extend toward the front upper place from shaft sleeve part 311, above-mentioned shaft sleeve part 311 outside faces outstanding one and cooresponding location, spring room 223 front and back teat 316, and installation teat 317 below the teat 316 of location, and these locating dowel pins 34 are distinctly erectly to be installed in two of buffing pad 31 to install on the teat 317, its top is stretched in the limit channels 225 of mount pad 2, these second pivot sheets 313 are 24 of two first pivot sheets that distinctly stretch to mount pad 2, first of homonymy, two pivot sheets 24,313 are distinctly articulated with a pivot 32 again.This buffing pad 31 can be a fulcrum pivot pendulum forward with two pivots 32 after being pivoted.

This axial buffer device 4 is to be erected at buffing pad 31 bottoms, it has a crane span structure 41 that is positioned at buffing pad 31 bottoms, above-mentioned crane span structure 41 has cooresponding two beam rings 412 in two left and right sides, and this axial buffer device 4 has more two buffer cells 42 that distinctly are installed in 311 of beam ring 412 and homonymy shaft sleeve part, each buffer cell 42 all comprises: one tightens the following central siphon 421 on beam ring 412, one spiral shell is located at down the locating bush 422 on central siphon 421 tops, one is erected at down the cushion cover 423 of central siphon 421 bottoms, one be installed in down in the hollow axle track of central siphon 421 and and the fixed position-limited lever 424 of cushion cover 423, one slides over the sliding sleeve 425 on the position-limited lever 424, one axial spring 426 between 423 of sliding sleeve 425 and cushion covers, one is fixed on the position-limited lever 424 and prevents that sliding sleeve 425 from skidding off the connecting element 427 of position-limited lever 424, one axle sleeve in the hollow axle track of following central siphon 421 and and sliding sleeve 425 fixed interlocks on central siphon 428, one axle sleeve is at the dust protecting cap 429 of last central siphon 428 outer peripheral edges, and one will go up on the shaft sleeve part 311 that central siphon 428 tops are cemented in buffing pad 31 in conjunction with pin 420.

Should preceding wheel unit 5 be to be erected at two buffer cells, 42 bottoms, wheel unit 5 has a front-wheel 51, and is installed in front wheel spindle 52 on the center shaft of front-wheel 51 before above-mentioned, and the corresponding connecting block 53 that distinctly is installed in front wheel spindle 52 left and right sides about two, above-mentioned connecting block 53 is that bundle is sandwiched in down central siphon 421 bottoms, has a bottom surface 531 for cushion cover 423 butts on it.

When front-wheel 51 is not subjected to up application force 6, be subjected to shoring of radial spring 33, these buffing pad 31 tops borrow two pivots 32 and connecting base 2 to be hubbed on together, then open because of two shoring of radial spring 33 bottom, when locating dowel pin 34 was resisted against block 226 the place aheads of connecting base 2, the setting angle that buffing pad 31 and connecting base are 2 will be fixed.And the setting height(from bottom) of 53 of buffing pad 31 and connecting blocks can that is to say that be subjected to shoring of both sides axial spring 426, central siphon 428 and 421 socket length of following central siphon are stationary state on this because shoring of axial spring 426 is fixing.

Consult Fig. 4,5, when front-wheel 51 of the present utility model is subjected to one up application force 6, this strand application force can form axial component 61 and radial component 62, wherein axial component 61 is parallel with antero-lateral rod 11 length bearing of trends, radial component 62 is vertical with antero-lateral rod 11 length bearing of trends, above-mentioned axial component 61 can cause fixed preceding wheel unit 5 together, following central siphon 421, move compression axial spring 426 on locating bush 422 and the cushion cover 423, produce the cushion effect that one is parallel to antero-lateral rod 11 length bearing of trends whereby, and absorbing axial component 61, the elastic force accumulated of axial spring 426 also can produce the element that moves on the script such as wheel unit 5 before the antagonistic force order and resets simultaneously.

At this moment together, the radial component 62 that acts on front-wheel 51 can be absorbed by shock absorber 3 radially, promptly these buffing pad 31 bottoms can be that fulcrum overcomes the power of shoring of radial spring 33 toward forward swing with pivot 32, and produce a cushion effect that is same as radial component 62 directions, the feasible axial buffer device 4 of buffing pad 31 belows and the cushion effect that preceding wheel unit 5 produces another kind of direction of being installed in is to absorb radial component 62.Identical reason, radial spring 33 by compression also can disengage the elastic force of accumulating, and allows axial buffer device 4 and preceding wheel unit 5 reset.

By above explanation as can be known, the utility model previous constructions really can be by means of the radially assembling of shock absorber 3 and connecting base 2, allow and originally can only produce the perambulator that is parallel to antero-lateral rod 11 length bearing of trend cushion effects, set up a vertical cushion effect, make the twice component that acts on front-wheel 51 all be obtained to absorb, therefore, the utility model previous designs provides the buffering effect of baby Geng Jia really.
