Abstract
The utility model discloses an adjusting handlebar shock-absorbing device of a bicycle, which is composed of an inner tube, an outer tube, suspending and fastening bolts, regulating nuts, etc. The utility model is characterized in that the walls of the inner tube and the outer tube are respectively provided with long or short splined grooves, an adjusting seam is arranged at the lower part of the inner tube, and the regulating nut is also provided with the splined groove and an elastic adjusting mechanism. The utility model has the advantages of high stability, and convenient regulation of a gap between the inner and the outer tubes; the utility model has the advantages that the rotation and the swing of the bicycle handlebar arranged at the upper part of the inner tube is effectively prevented, and the vibration-damping effect is increased. The utility model is also suitable for tricycles with a handlebar, power-assisted bicycles with a handlebar, etc.
Description
The utility model relates to a kind of automatic shock-proof device, particularly bicycle handle bar's shock absorbing apparatus.
The bicycle that common people use, handlebar does not all have shock absorbing apparatus, because of handlebar shakes for a long time, arm is not felt well when riding, and uses as adopting motor bike, is arranged on the two bar dual spring Shock absorbers on the handlebar front fork, and price is more expensive, complex structure.Application number is that 952408082 " shock absorbing apparatus in the bicycle handle bar " provides a kind of structure simpler, be installed in the handlebar shock absorbing apparatus in the bicycle front fork, its main weak point is that pipe easily rotates when the up-and-down movement of outer tube inside in the Shock absorber, the chute cell wall is also easy to wear, in case wearing and tearing, the gap can not free adjustment, influences result of use.The elasticity of shock-proof spring can not free adjustment, and period of service one is long, and shock-proof effect will reduce.
The purpose of this utility model provides a kind of inner and outer pipes and cooperates closely, good stability, and interior Guan Buhui rotates in outer tube and extracts, and chute cell wall gap and shock-proof spring length can be regulated long service life, the automatic shock-proof device of good damping effect.
The utility model comprises outer tube (9), interior pipe (5), interior pipe (5) bottom is provided with setting nut (11), this nut is connected by the fastening screw nut (3) of hanging bolt (1) with interior pipe (5) top, silently nut (14) is arranged at outer tube (9) bottom, be provided with shock-proof spring (12) between this nut and the setting nut (11), it is characterized by outer tube (9) tube wall and be suppressed with the short groove (9 ') of spline, corresponding tube wall of interior pipe (5) is suppressed with the spline elongated slot (5 ') that is complementary with the short groove of spline, and the outer wall of spline elongated slot (5 ') can slide up and down at the inwall of the short groove of spline (9 '); Setting nut (11) top is round table-like, and outer wall is provided with the spline that is complementary with spline elongated slot (5 '), and interior pipe (5) bottom tube wall is provided with regulates seam (10); Shock-proof spring (12) bottom is provided with the elastic force regulating mechanism, and this mechanism is made up of the supporting spring (13) that is screwed in the adjusting bolt (15) on the nut (14) silently and regulates bolt (15) top.
Can establish lining (7) between hanging bolt (1) and interior pipe (5) inwall, lining (7) is provided with ball (8), when interior pipe (5) up-and-down movement, is used to reduce the friction of inside and outside tube wall.
Inner and outer pipes of the present utility model is that spline connects, good stability, pipe rotates in outer tube in preventing effectively, and the adjusting that can pass through on hanging bolt, setting nut and the inner pipe wall is stitched, regulate the gap between the inner and outer pipes, regulate shock-proof spring elastic force by the elastic force regulating mechanism, improve shock-proof effect and working stability.
Accompanying drawing 1 is gone into the structural representation in the pipe on the bicycle front fork for the utility model plug-in mounting.
Accompanying drawing 2 is the A-A cutaway view of accompanying drawing 1.
Accompanying drawing 3 is gone into the structural representation in the pipe on the bicycle front fork for another embodiment plug-in mounting of the present utility model.
Among the figure: 1-hanging bolt, 2-hollow adjusting bolt, 3-fastening screw nut, 4-captive nut, 5-interior pipe, 5 '-the spline elongated slot, 6-compress pipe, 7-lining, 8-ball, 9-outer tube, 9 '-the short groove of spline, 10-regulate and stitch, 11-setting nut, 12-shock-proof spring, 13-supporting spring, 14-silently nuts, 15-adjusting bolt, 16-jump ring.
Further describe the utility model below in conjunction with drawings and Examples.
Referring to accompanying drawing 1, during use, outer tube of the present utility model (9) inserts in the last pipe of bicycle front fork, and bicycle handle bar is installed on interior pipe (5) top.Handlebar and bicycle front fork are represented with long and two-short dash line in the accompanying drawing.Hanging bolt in the accompanying drawing 1 (1) passes setting nut (11) and is threaded with fastening screw nut (3), the captive nut (4) on interior pipe (5) top from the bottom, tighten hanging bolt (1), can make setting nut (11) along interior pipe (5) inwall upward movement, and owing to regulate the effect of seam (10), interior pipe (5) bottom tube wall is strutted, regulate inner and outer pipe tube wall gap, rock with bicycle handle bar's rotation of avoiding being installed in interior pipe (5) top.Bolt (15) is regulated in rotation, can make the upper and lower motion of supporting spring (13), changes the length of shock-proof spring (12), to regulate elastic force.
Accompanying drawing 3 is another embodiment of the utility model, hanging bolt (1) is inserted by interior pipe (5) top, hanging bolt (1) outside is set up one and is compressed pipe (6), a hollow adjusting bolt (2) is set up on top, hollow adjusting bolt (2) is threaded with fastening screw nut (3), captive nut (4), hanging bolt (1) bottom is threaded with setting nut (11), this structure can make setting nut (11) up-and-down movement from interior pipe (5) top by hanging bolt (1) more easily, to regulate the gap of inside and outside tube wall, improve shock-proof effect and working stability.
Claims (2)
