Description

Shock-absorbing saddle-pillar of bicycle

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

Bicycle is a kind of indispensable vehicle in our country, along with people's lives improve gradually, become clear day by day at the exquisite of comfort aspect, 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 hill path, rural area or when crossing railway, always the hardship that will be jolted 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: in the lower saddle seat tube upper end, have overall diameter and be slightly less than lower saddle seat tube interior diameter upper saddle seat sliding tube, strip groove is corresponding with bar shaped boss on the one side inside face of following saddle sliding tube top having on upper saddle seat sliding tube one side external surface, has spring in upper saddle seat sliding tube, lower saddle seat tube inside, below spring, has adjusting pad, below adjusting pad, have bonnet and, lower saddle seat tube lower end surface phase clamping.

When using, elder generation packs spring in the upper saddle seat sliding tube, again the upper saddle seat sliding tube is from bottom to top passed lower saddle seat tube, and make the strip groove on upper saddle seat sliding tube one side external surface corresponding with lower saddle seat tube top one side in-to-in bar shaped boss identical, can slide up and down, below spring, have adjusting pad, can adjust spring be stressed the back suitable height, below adjusting pad, have a bonnet, play sealing process.

The utility model compared with prior art has following advantage:

1, simple in structure, material-saving, cost is low;

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

Concrete structure of the present utility model and embodiment are provided by the following drawings.

Fig. 1 is that the utility model overall structure is cutd open and shown scheme drawing.

Below in conjunction with accompanying drawing concrete structure of the present utility model and embodiment are further specified.

Shown in accompanying drawing 1, bicycle Saddle with damping function pipe, it is the saddle bottom, a kind of connecting device between the vehicle frame top, see that from appearance it is made up of upper saddle seat sliding tube 1 and lower saddle seat tube 2 two large divisions, in lower saddle seat tube 2 upper ends, have overall diameter and be slightly less than the upper saddle seat sliding tube 1 of saddle 2 down, have strip groove 7 and 6 corresponding the coincideing of bar shaped boss on the one side inside face of lower saddle seat tube 2 tops on upper saddle seat sliding tube 1 one side external surfaces, can slide up and down, at upper saddle seat sliding tube 1, has spring 3 in the lower saddle seat tube 2, play buffer action, below spring 3, has adjusting pad 4, adjusting pad 4 can be adjusted the spring appropriateness, it is body weight according to the cyclist, when difference is big, be added under the adjusting pad, reach with the thickness of paper shell pad and what and spring can be depressed and can not be pressed onto the end, below adjusting pad 4, has bonnet 5, bonnet 5 diameters are identical with lower saddle seat tube lower end interior diameter, on the bonnet cylindrical, have three gear pieces that are square, bonnet 5 is advanced in the lower saddle seat tube 2 lower end pipes turning clockwise and interior last three the square gear piece clampings mutually of lower saddle seat tube 2 lower end outer tubes.
