Description

Enclosed elastic bicycle saddle

The utility model relates to a kind of bicycle saddle.

Existing bicycle, all be to do the supporting damping by two very short springs in its saddle to use, the damping effect that this short spring produced is very limited, when the road not at ordinary times, the vibrations of bicycle are to be difficult to eliminate to cyclist's harmful effect by the elasticity of this short spring.Some present patents are the Chinese patent " elasticity bike saddle " of CN2084902U as patent publication No., all lay particular emphasis on the improvement of saddle inner structure, and because the dimensional restriction of saddle make that its improvement effect is not satisfactory, or cost is too high.On the other hand, as a kind of routine vehicle of long-term use, the vibrations of bicycle all have harmful effect to human skeleton and internal organ, are easy to cause some diseases, and especially old and young weakling is unfavorable for its health especially.

The purpose of this utility model is on the basis of existing bicycle, designs the closed elasticity bicycle saddle of simple in structure a, excellent spring, can greatly eliminate the influence of the vibrations of bicycle to human body.

The technical solution of the utility model is as follows: it is by saddle (1), support (2), threaded sleeve (3), H pipe (4), spring (5), nut (6), pressure spring (7) and (8) constitute, support (2) is affixed by three forks and the saddle (1) on its top, two legs that one is long and the other is short are arranged at support (2) bottom, threaded sleeve (3) is socketed on support (2) long foot, spring (5) is socketed on support (2) long foot again, the end of support (2) long foot has outside thread, by screwing nut (6) with stability thread sleeve pipe (3) and spring (5); On the long end of H pipe (4) negative thread is arranged, can spin mutually, threaded sleeve (3) and H pipe (4) are linked with the outside thread on the threaded sleeve (3) on being socketed in support (2); The short leg of the short direct socket support of end (2) of H pipe (4); The long end of H pipe (4) is placed with pressure spring (7) and (8) respectively with the bottom of short end; The footpath is a little less than the internal diameter of cant beam pipe (10) behind the spider of bicycle outside the long end of H pipe (4).Inserting the length end of the H pipe (4) of back cant beam pipe (10), is to tighten fixing by tightening screw (9).

Below in conjunction with accompanying drawing in detail the utility model is described in detail.

Fig. 1 is a front elevation of the present utility model;

Fig. 2 is the front elevation that unloads behind the H pipe (4) of the present utility model;

Fig. 3 is the cutaway view of H pipe (4);

Fig. 4 is the scheme drawing of support (2);

Fig. 5 is the birds-eye view of support (2);

Fig. 6 is the birds-eye view of saddle (1);

Fig. 7 is that the utility model is installed in the scheme drawing on the bicycle.

Fig. 1～Fig. 7 has reflected structure of the present utility model.The shape of saddle (1) is as shown in Fig. 1 and Fig. 6, just the same with the ordinary bicycle saddle, just inside there is no short spring, support (2) as shown in Figure 4 and Figure 5, three forks on its top have an aperture respectively, and corresponding with three screws of saddle (1) bottom, be about to saddle (1) and support (2) links with three screws.When assembling the utility model, earlier threaded sleeve (3) is socketed on the long foot of support (2), socket spring (5) again, screw on nut (6) then, at this moment state as shown in Figure 2, again the long end and the short end of H pipe (4) are inserted pressure spring (7) and (8) respectively, long foot and the short leg of distinguishing corresponding support (2) then socket-connect, by rotation threaded sleeve (3), its outside thread is spun mutually with the negative thread of the long end of H pipe (4), H pipe (4) and threaded sleeve (3) are linked.At last the length of H pipe (4) end is inserted the back cant beam pipe (10) of bicycle tripod, blocks back cant beam pipe (10) until the transverse tube of H pipe (4), tighten by tightening screw (9) more fixing, as shown in Figure 7.Like this, when bicycle shakes because of Uneven road, two kinds of situations are arranged: the one, when last human weight of saddle (1) and shaking force were downward, then long foot and the short leg by support (2) directly was pressed on pressure spring (7) and (8); The 2nd, when shaking force makes progress, saddle (1) and support (2) upward movement, because H pipe (4) and threaded sleeve (3) are fixed, then spring (5) is compressed, so the amplitude of saddle (1) upward movement is exceeded with the compression degree of spring (5).Therefore, when bicycle shakes, because pressure spring (7) and (8) have excellent elasticity, and the buffering and the damping effect of spring (5), thereby eliminated the harmful effect of bicycle vibrations to the cyclist, strengthened the elasticity and the anti seismic efficiency of vehicle seat, it is comfortable that the cyclist is felt safe.In addition because pressure spring (7) and (8) are to be placed in the osed top H pipe (4), make the utility model profile succinctly, dependable performance, long service life.

In sum, the utility model not only has excellent spring, reliable, advantage such as anti-seismic performance is strong, and profile is succinct, long service life helps cyclist's health, is particularly suitable for old and young weakling institute by bike, and simple in structure, productive costs is low, is easy to produce.Need not to change other structure of bicycle.The utility model will replace existing bicycle saddle, become new bicycle vehicle seat health, practical more.

Claims (2)

1, a kind of closed elasticity bicycle saddle, it is characterized in that it being by saddle (1), support (2), threaded sleeve (3), H pipe (4), spring (5), nut (6), pressure spring (7) and (8) constitute, support (2) is affixed by three forks and the saddle (1) on its top, two legs that one is long and the other is short are arranged at support (2) bottom, threaded sleeve (3) is socketed on support (2) long foot, spring (5) is socketed on support (2) long foot again, the end of support (2) long foot has outside thread, by screwing nut (6) with stability thread sleeve pipe (3) and spring (5); On the long end of H pipe (4) negative thread is arranged, can spin mutually, threaded sleeve and H pipe (4) are linked with the outside thread on the threaded sleeve (3) on being socketed in support (2); The short leg of the short direct socket support of end (2) of H pipe (4); The long end of H pipe (4) is placed with pressure spring (7) and (8) respectively with the bottom of short end; The footpath is a little less than the internal diameter of cant beam pipe (10) behind the spider of bicycle outside the long end of H pipe (4).

2, closed elasticity bicycle saddle according to claim 1, the length end of the H pipe (4) of cant beam pipe (10) is to tighten fixing by tightening screw (9) after it is characterized in that inserting.
