Description

Bicycle seat pillar with vibration absorber

The utility model relates to a kind of bicycle shock absorption device, especially a kind of bicycle Saddle with damping function pipe.

Bicycle is the indispensable vehicle in our country, along with people's lives improve gradually, needs in comfort aspect become clear day by day, but making little progress aspect the bicycle improvement, except increasing in recent years the speed-changing mechanism, is of all shapes and colors, relevant to the road uneven, particularly in the rural area, hill path or when crossing railway, the hardship of the ripple of always will being run is suddenly waited to improve.

The purpose of this utility model provides the saddle device that vibrations are reduced on a kind of road at uneven by bike the time.

The utility model is achieved like this: it comprises saddle sliding tube, the main two parts of fixed mount, the external diameter of sliding tube is slightly less than the interior diameter of fixed mount, has the corresponding through slot of oblong respectively in the left and right sides of saddle sliding tube middle part, has open recess respectively in the left and right sides, fixed mount upper end, in groove, has a retainingf key that passes through slot, have fastening nut in the outside, fixed mount upper end, in fixed mount, have spring, have adjusting pad in the spring bottom.

When using, saddle slip pipe bottom is inserted in the fixed mount, again key is passed in the open recess of the left and right sides, fixed mount upper end of packing into behind the through slot of sliding tube both sides, fix with fastening nut, prevent that sliding tube from swinging, can reach sliding tube again and move up and down in a certain direction, under action of the spring, reach cushioning effect.

The utility model compared with prior art has following advantage:

1, simple in structure, cost is low;

2, comfortable damping is suitable for road injustice or rural area and uses.
