Description
Technical field
The utility model belongs to shock absorption device field, particularly relates to a kind of damping device for baby carriage.
Background technology
Shock absorption device is mainly used to the concussion produced when relaxing road shocks, if shock absorption device rigidity is too soft, vehicle body will fluctuate by vertical bounce; If shock absorption device rigidity is too hard, too large dumping force will be produced, affect car body and normally work.The perambulator sold in the market is mainly divided into without shock-absorbing type perambulator and shock-absorbing type perambulator, without shock-absorbing type perambulator when road surface fluctuation is larger, there is impact and causes greatly the uncomfortable phenomenon of the baby in vehicle seat; Shock-absorbing type pushchair and front using uprighting spring to carry out simple damping between pipe link, although the impact having relaxed road surface fluctuation, relax the attack time long, the resistance to overturning of perambulator car body and traveling comfort are all poor.
Summary of the invention
The utility model provides a kind of damping device for baby carriage, with solve propose in above-mentioned background technology mitigation attack time length, poor stability, traveling comfort difference problem.
The technical matters that the utility model solves realizes by the following technical solutions: the utility model provides a kind of damping device for baby carriage, comprise tie rod, front-wheel and damping, be provided with damping between described tie rod and front-wheel, described front-wheel is provided with wheel carrier, described damping comprises upper steel plate, lower steel plate, expansion link, adjusting knob, locating plate, damping spring, spring cover and spring perch, be fixed on the downside of described lower steel plate on wheel carrier, on the upside of described lower steel plate, two ends, left and right are fixed with two expansion link bottoms respectively, described two expansion link tops are separately fixed at two ends, left and right on the downside of corresponding upper steel plate, described expansion link is provided with adjusting knob, on the upside of the linking springs seat of described damping spring lower end, on the downside of the linking springs lid of upper end, middle side part on lower steel plate is fixed on the downside of described spring perch, be fixed on the upside of described spring cover on the downside of locating plate, tie rod bottom is connected on the upside of described locating plate, described tie rod upper end is through being fixedly connected with it in the middle part of upper steel plate.
Described front-wheel is two-wheel.
Described damping also comprises sleeve, and described sleeve upper end is connected on tie rod, and lower end is connected on wheel carrier.
Cushion rubber is provided with on the upside of described locating plate and between tie rod.
A fixed gap is all left between described locating plate and two expansion links.
The beneficial effects of the utility model are:
1, the utility model adopts the structure design mode that damping spring and two expansion links cooperatively interact, and realizes the well-balanced adjustment of softness and hardness, reach and relax the effect that the attack time is short, stability is high, traveling comfort is good during the fluctuation of road surface.
2, front-wheel of the present utility model is two-wheel, more steady in the process that two-wheel can make perambulator walk, and when receiving road shocks, the dynamics of waving of perambulator entirety is little.
3, damping of the present utility model also comprises sleeve, and when using for a long time, sleeve can make the internal part of damping keep clean, improves overall appearance degree, increases the service life.
4, on the upside of locating plate of the present utility model and be provided with cushion rubber between tie rod, during road shocks great efforts, cushion rubber can avoid the shock between locating plate and upper steel plate to damage.
5, all leave a fixed gap between locating plate of the present utility model and two expansion links, during road shocks great efforts, between the expansion link avoiding locating plate both sides close with it, occur frictional impact, affect stability and the traveling comfort of perambulator car body.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-tie rod, 2-front-wheel, 3-damping, 4-wheel carrier, 5-upper steel plate, 6-lower steel plate, 7-expansion link, 8-adjusting knob, 9-locating plate, 10-damping spring, 11-spring cover, 12-spring perch, 13-sleeve, 14-cushion rubber.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, the present embodiment comprises tie rod 1, front-wheel 2 and damping 3, is provided with damping 3 between tie rod 1 and front-wheel 2, front-wheel 2 is provided with wheel carrier 4, damping 3 comprises upper steel plate 5, lower steel plate 6, expansion link 7, adjusting knob 8, locating plate 9, damping spring 10, spring cover 11, spring perch 12 and sleeve 13, be fixed on wheel carrier 4 on the downside of lower steel plate 6, on the upside of lower steel plate 6, two ends, left and right are fixed with two expansion link 7 bottoms respectively, two expansion link 7 tops are separately fixed at two ends, left and right on the downside of corresponding upper steel plate 5, expansion link 7 is provided with adjusting knob 8, on the upside of damping spring 10 lower end linking springs seat 12, on the downside of upper end linking springs lid 11, middle side part on lower steel plate 6 is fixed on the downside of spring perch 12, be fixed on the downside of locating plate 9 on the upside of spring cover 11, tie rod 1 bottom is connected on the upside of locating plate 9, cushion rubber 14 is provided with on the upside of locating plate 9 and between tie rod 1, tie rod 1 upper end is through being fixedly connected with it in the middle part of upper steel plate 5, sleeve 13 upper end is connected on tie rod 1, lower end is connected on wheel carrier 4.
The working process of this example: when Uneven road, front-wheel 2 will produce fluctuation, wheel carrier 4 on front-wheel 2 also can fluctuate thereupon, when fluctuating less, the fluctuation that two expansion links 7 between upper steel plate 5 and lower steel plate 6 utilize itself rigidity can absorb wheel carrier 4 to bring, thus the vibrations that the tie rod 1 avoiding upper steel plate 5 upper end brings to perambulator vehicle body; When fluctuating larger, two expansion links 7 between upper steel plate 5 and lower steel plate 6 can only absorb the part fluctuation that wheel carrier 4 brings, damping spring 10 between spring cover 11 and spring perch 12 there will be bounce, and bounce suppresses the vibrations of tie rod 1 by locating plate 9.Required damping Damping Scale can also be regulated voluntarily according to the difference of road conditions, first sleeve 13 is unloaded from tie rod 1 and wheel carrier 4, unscrew the adjusting knob 8 on expansion link 7, upper steel plate 5 is pressed down or pull-up drives two expansion links 7 to move down or on move, reach required damping damping position then to tighten adjusting knob 8 expansion link 7 is fixed, just sleeve 13 is arranged on tie rod 1 and wheel carrier 4 again, and car body becomes can normally walk.
Utilize technical scheme described in the utility model, or those skilled in the art being under the inspiration of technical solutions of the utility model, designing similar technical scheme, and reach above-mentioned technique effect, is all fall into protection domain of the present utility model.
