Description
Technical field
The utility model relates to the technical field of mobility scooter for old people, is specifically related to the pressure-type shock device for mobility scooter for old people.
Background technique
Along with the development of society, the raising of people's living standard, the elderly and handicapped people also get more and more and use scooter as the traffic tool, greatly reduce the inconvenience of elderly and the disabled's trip, but because elderly and the disabled's fitness is relatively weak, this just requires relatively high to the shock mitigation system of scooter, existing scooter shock mitigation system damping effect is not ideal, when particularly road conditions are bad, comparatively large to the body burden of the elderly and the disabled, and damper of vehicle topmost be exactly the shockproof mechanism of tire both sides.
Summary of the invention
Technical problem to be solved in the utility model is, provides that a kind of structure is simple, the pressure-type shock device for mobility scooter for old people of good damping effect.
For achieving the above object, the technological scheme that the utility model is taked is:
For the pressure-type shock device of mobility scooter for old people, comprise wheel shaft, it is characterized in that: described wheel shaft two ends are equipped with shock absorber, described shock absorber comprises the outer tube of tubular, be located at the capping on outer tube top, through capping center through hole and the piston rod goed deep in outer tube, be located at the piston head of piston rod bottom, outer tube inner cavity is divided into upper plenum and lower cavity by this piston head, described outer tube upper end wall is provided with from outer toward interior one-way valve one, middle part is provided with outlet valve, described piston head is provided with one-way valve two from top to bottom, survey in described outer tube top and be provided with seal groove, described seal groove is provided with seal ring.
As preferably, described shock absorber lower end is fixed on wheel shaft two ends by link.。
As preferably, described outlet valve is from interior unidirectional outward, and it opens required pressure higher than one-way valve two.
As preferably, when described piston head up moves, highly one-way valve one can not be exceeded.
As preferably, described outer tube bottom is provided with step, and described step is provided with packing ring.
Pressure-type shock device for mobility scooter for old people described in the utility model, compensate for the deficiencies in the prior art, adopts multiple pneumatic bumper, reach good damping effect, and structure is simple, and cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of shock absorber in the utility model.
Embodiment
Below in conjunction with accompanying drawing and example, the utility model is described further.
As shown in the figure, for the pressure-type shock device of mobility scooter for old people, comprise wheel shaft 315, it is characterized in that: described wheel shaft 315 two ends are equipped with shock absorber, described shock absorber comprises the outer tube 305 of tubular, be located at the capping 313 on outer tube 305 top, through capping 313 center through hole and the piston rod 303 goed deep in outer tube 305, be located at the piston head 306 of piston rod 303 bottom, outer tube 305 inner cavity is divided into upper plenum 304 and lower cavity 307 by this piston head 306, described outer tube 305 upper end wall is provided with from outer toward interior one-way valve 1, middle part is provided with outlet valve 311, described piston head 306 is provided with one-way valve 2 310 from top to bottom, survey in described outer tube 305 top and be provided with seal groove 302, described seal groove 302 is provided with seal ring 301, described shock absorber lower end is fixed on wheel shaft 315 two ends by link 314, described outlet valve 311 is from interior unidirectional outward, it opens required pressure higher than one-way valve 2 310, when described piston head 306 up moves, height can not exceed one-way valve 1, described outer tube 305 inner bottom is provided with step 308, described step 308 is provided with packing ring 309.
When piston head 306 moves downward, outside air enters upper plenum 304 from one-way valve 1, when piston head 306 moves upward, open required pressure due to outlet valve 311 and be greater than one-way valve 2 310, therefore one-way valve 2 310 is first opened, air in upper plenum 304 preferentially enters lower cavity 307 from one-way valve 2 310, and the air pressure instantly in cavity 307 increases to and enough opens outlet valve 311, when piston head 306 is in again above outlet valve 311, air in lower cavity 307 can be discharged by outlet valve 311, this ensures that there piston head 306 to be in outlet valve about 311 all the time and can not to cross high pressure and do not get off, outer tube 305 top is provided with seal ring 301, and adopt capping 313 to compress, ensure that good sealing, outer tube inner bottom part is provided with step 308, described step 308 is provided with packing ring 309, even if piston head also can not damage bottom clashing into like this.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., be all included within protection domain of the present utility model.
