Abstract

The utility model relates to a bicycle vibration damper; a base rod 3 of the vibration damper is inserted into the other end of a socket sleeve 5 and two long strip holes 6 which are extended in the axial direction and correspond to each other are arranged at the corresponding position of the wall of the lower part of the base rod; a flat pin 8 penetrates horizontally two holes 6 and two ends of the flat pin are fixed at the lower end of the wall of the socket sleeve 5; the lower end of a pressing spring 2 in the base rod 3 is supported by a support ring 7 which is cooperated with the flat pin 8 and the upper end of the pressing spring is supported by an adjustable plug 1 and the adjustable plug can adjust the pre-tightening force of the pressing spring 2; the lower end of the socket sleeve 5 is clamped on a bicycle frame and the upper end of the base rod is clamped on a saddle. When the people ride the bicycle to travel on the road which is either convex or concave or the earth-rock road, the base rod slides in the socket sleeve to make the pressing spring compressed and restored with achieving the damping effect, thus having the effects of delivering comfort, protecting the brain, protecting the bicycle and body-building. The vibration damper has small volume, small weight, is suitable for bicycles of different models and the people with different body weights.

Description

The bicycle shock-absorption device

The utility model relates to a kind of shock absorber, specifically a kind of shock absorber that is installed under the bicycle saddle.

The bicycle that people rode, its vibration damping are that the effectiveness in vibration suppression of travelling on smooth road is all right, if travel on scraggly road, particularly travels on Tu Shilu, will produce stronger jolting, and makes the people feel uncomfortable by the spring on the vehicle seat.The people causes brain damage easily if long-term acceptance is jolted, and note meaning power is gone down, and influences people's physical and mental health.

The purpose of this utility model provides a kind of bicycle shock-absorption device, only feels slight vibration when the people is travelled on rough and uneven in surface or Tu Shilu by bike.

In order to realize the purpose of this utility model, the concrete technical scheme of its realization is: this shock absorber mainly is clamped in tubulose cover for seat on the vehicle frame, an end by an end and inserts in the cover for seat tubular holder bar, stage clip and the cotter pilotage of other end clamping on vehicle seat and form.The bottom corresponding positions of seat bar wall is equipped with the strip hole that stretch on the cooresponding axial edge of two-phase, and its cotter pilotage passes across the relevant position, lower end that two strip holes and two ends are fixed on the cover for seat wall; Be positioned at the carrier ring supporting of lower end by matching with cotter pilotage of the stage clip of a bar, the upper end of stage clip is supported by adjustable plug.The seat bar slides up and down drive stage clip compression return and reaches the vibration damping purpose.

The utility model just increases a cover for seat, seat bar and stage clip between vehicle frame and vehicle seat, the people rides when sailing, and stage clip compression and back position just can reach effectiveness in vibration suppression under the guiding of strip hole and cotter pilotage on the present bar, play comfortable, protect brain, protect car, body building function.Because stage clip is located in the bar hole and by reversing the predetermincd tension of the default stage clip of adjustable plug, can make the shock absorber volume little, in light weight, is fit to the different weight people and uses.

Below in conjunction with drawings and Examples the utility model is made detailed description.

Fig. 1 cuts open constructional drawing for the office of the utility model bicycle shock-absorption device.

In Fig. 1, this bicycle shock-absorption device mainly by an end be clamped in that tubulose cover for seat 5, one ends on the vehicle frame insert in the cover for seat 5, the other end is clamped in tubular holder bar 3 on the vehicle seat and stage clip 2 and cotter pilotage 8 are formed.The relevant position of seat bar 3 lower part walls is milled with the strip hole 6 that stretch on two corresponding axial edges, and cotter pilotage 8 passes across the relevant position, lower end that two strip holes, 6 its two ends are fixed on cover for seat 5 walls; The lower end that is positioned at the stage clip 2 of a bar 3 is supported by carrier ring 7, and carrier ring 7 lower ends cooperate with cotter pilotage 8 circular arcs, and the upper end of stage clip 2 is by adjustable plug 1 supporting.There is an axially extending bore 13 to feed the stage clip chamber on the adjustable plug 1, as annotating machine oil in order to lubricated bar, cover, pin; Adjustable plug 1 external diameter cooperates with seat bar 3 upper end inner hole threads, and the predetermincd tension of adjusting plug setting stage clip can be fit to the different weight people and ride usefulness.Strip hole 6 recited above and cotter pilotage 8 cooperates for movable, when seat bar 3 in cover for seat 5 during up-and-down movement stage clip 2 compress and returned damping of vibrations.The lower end of seat bar 3 is fixed with cylindricality damping rubber block 12 by pin 11, and this piece tightly blocks a bar lower end, makes the top of determining form oil cabinet 9, when butter makes the stage clip return on the indoor notes during assembling from row buffering.Two ends in cover for seat 5 pipes stud with nylon jacket 4 and following nylon jacket 10 on the abrasion resistant, to change with being convenient to along the long life.In addition, cotter pilotage 8 is located at down and can makes the height adjustment range of vehicle seat big, adapts to multiple vehicle and uses with different height people.

The principle of work of this bicycle shock-absorption device is: when the people rode bicycle and travels on rough and uneven in surface or Tu Shilu, a seat bar slided in cover for seat and makes stage clip compress returning movement to play damping of vibrations.

Claims
