Abstract
The utility model discloses a damping device on bicycle handlebar post, handlebar 10 is horizontal on handlebar post 20, handlebar post 20 is the hollow body in step form hole, the hexagonal cross-section hole of hypomere and the cooperation of the hexagonal outer wall of interior pole setting 40 in it, there is one to hang tight screw rod 50 in the interior pole setting 40, its lower extreme even has hangs tight nut 80, this female 80 makes its and handlebar post 20 constitution static cooperation with the first 41 cooperation of tensioning, be equipped with shock attenuation pressure spring 70 between tensioning head 41 and the handlebar post 20, the impulsive force that ground was used on the wheel transmits handlebar 10 after the shock attenuation of pressure spring 70, vibrations have been slowed down effectively.
Description
The utility model discloses the shock absorption device on a kind of bicycle handle bar post.
Existing bicycle handle bar to the connecting mode of front fork part is to belong to be rigidly connected basically, the power of ground effects on front-wheel just plays extremely limited damping, buffering effect through the elasticity of front-wheel self, reach on hand through handlebar then, what the cyclist experienced is the sharp pounding impulse force, because violent vibrations, sometimes even dangerous situation such as handle can occur taking off and cause damage.
The purpose of this utility model is to provide a kind of bicycle handle bar post bumper, to slow down the handlebar seismism of jolting and causing because of ground.
For achieving the above object, the technical solution adopted in the utility model is: bicycle handle bar's bumper, the horizontal upper end of handlebar at handle-bar stem, handle-bar stem is the hollow tubular in a up big and down small step-like hole, lower semisection cross section is hexagonal hole in it, this hole is that hexagonal outer wall cooperates with interior vertical rod cross section, in the through hole of the inner up/down perforation of interior vertical rod a hanging screw is set, its lower end is connected with the nut that hangs tight that a profile is a frustum, its the little directly tensioning of vertical rod lower end setting 41 in end from bottom to top extends, the tensioning head is the shell-like under shed, be evenly equipped with some open slots on its perisporium, between the upper surface of tensioning head and the lower surface of handle-bar stem a stage clip is set, the hypomere of described handle-bar stem and interior vertical rod are positioned at vertical tube of front fork, it between handle-bar stem and the vertical tube of front fork running-fit, it between tensioning head and the vertical tube of front fork close fit, there is plug screw lid at the upper end open place of handle-bar stem, be provided with pad between the hexagonal spiral shell head of hanging screw and the upper surface of interior vertical rod, be provided with stage clip between the endoporus table top of the lower surface of pad and handle-bar stem.
As shown from the above technical solution, the impulsive force that jolts that acts on the front fork is delivered on the handle-bar stem after the stage clip buffering again, vibrations impulse force on the handlebar is cushioned transition significantly like this, the hand of handle will no longer stand the strong impulse force that strenuous vibration produces by bike, like this, can effectively avoid taking off phenomenon favourable safe driving because of what strong impulse force produced.

Embodiment
As shown in Figure 1, handlebar 10 horizontal upper ends at handle-bar stem 20, handle-bar stem 20 is the hollow body in a up big and down small step-like hole, lower semisection cross section is hexagonal hole in it, this hole also cooperates for hexagonal outer wall with interior vertical rod 40 cross sections, as shown in Figure 2, being arranged to hexagonal cooperation cross section is for driving torque is provided, when promptly rotating handgrip 10, when handle-bar stem 20 rotates synchronously with handlebar 10, interior vertical rod 40 also will be rotated synchronously, in order to realize the transmission of above-mentioned driving torque, have more than the version that is limited to above-mentioned interior hexagonal section, the utility model also should comprise similarly other odd-shaped cross section form except that round section.
Be axial running-fit between handle-bar stem 20 and the interior vertical rod 40, be that both axially can relatively move, interior vertical rod 40 inside are the through hole of up/down perforation, one hanging screw 50 is set in it, its lower end be connected with a profile be frustum hang tight nut 80, what hang tight nut 80 is little straight in end extends in the tensioning 41 of vertical rod 40 lower ends, tensioning 41 is the shell-like under shed, uniform some open slots 411 on its perisporium, referring to Fig. 3, when tightening hanging screw 80, hang tight nut 80 and will squeeze and support tight 41, its lower ending opening groove 411 is opened and and vertical tube of front fork 60 between constitute the failure-free close fit.The hypomere of handle-bar stem 20 and interior vertical rod 40 are positioned at vertical tube of front fork 60, be running-fit between handle-bar stem 20 and the vertical tube of front fork 60, between the upper surface of tensioning 41 and the lower surface of handle-bar stem 40 stage clip 70 is set, when handle-bar stem 20 moves down with respect to vertical tube of front fork 60, stage clip 70 is compressed, elastic stretch then, thereby violent physical shock can be slowed down, realize the effect of damping.
The upper end open place of handle-bar stem 20 is provided with plug screw lid 21, is provided with pad 90 between the hexagonal spiral shell head of hanging screw 50 and the upper surface of interior vertical rod 40, between the endoporus table top of the lower surface of this pad 90 and handle-bar stem 20 stage clip 30 is set.Plug screw lid 21 is treated to load onto after various members install, it makes and keeps neat in appearance and can avoid impurities and dust to enter in the hole, stage clip 30 can slow down the speed when moving on the handle-bar stem 20, and the engagement limits effect by pad 90 and stage clip 30, avoid handle-bar stem 20 from vertical tube of front fork 60, to extract out.
Assembling in the utility model between vertical tube of front fork 60 and the car body crossbeam belongs to prior art, repeats no more herein.
