Description

Anti-vibration bicycle

Technical field

The utility model relates to bicycle, especially relates to the structure of anti-vibration bicycle.

Background technology

Bicycle is a kind of popular traffic and body-building apparatus.Because bicycle, especially mountain bike usually travel on rugged road, therefore, shock absorbing apparatus need be installed on bicycle.The incabloc function of existing anti-vibration bicycle is mainly realized by Shock absorber and rotating shaft five-way.Shock absorber is fixedly mounted between the rear column in back vent and the preceding triangle, the rotating shaft five-way is installed between the lower end of back vent and preceding triangle, when bicycle is given a shock, Shock absorber is compressed, and back vent is by the triangle rotation forward of rotating shaft five-way, to change into horizontal power by the rotating shaft five-way from the ground-surface power that makes progress, thereby play the effect of shock-absorbing.But, in the existing anti-vibration bicycle,, can not fold because its Shock absorber is fixedly mounted between rear column and the back vent, therefore, when parking, need occupy bigger space.

Summary of the invention

The purpose of this utility model is that anti-vibration bicycle can not fold the problem of parking in the solution prior art, and provides a kind of simple in structure, can fold the anti-vibration bicycle of parking.

The purpose of this utility model is to realize like this, a kind of anti-vibration bicycle, comprise vehicle frame, front and rear fork and front and back wheel, described vehicle frame comprises A-pillar and by preceding triangle that spreader, batter post and rear column constituted, between the lower end of preceding triangle and back vent, the rotating shaft five-way is installed, between rear column and back vent, Shock absorber is installed, it is characterized in that: flexibly connect for detouchable between at least one end of described Shock absorber and the bicycle; The end of captiveing joint at rotating shaft five-way and back vent is provided with spacer, also is fixed with fixedly fetching on batter post, and when the five-way rotation around the shaft of described spacer, described spacer can be inconsistent and fixing with described fixedly fetching.

Described spacer both can be fixed on the rotating shaft five-way, also can be fixed on the back vent.

Implement anti-vibration bicycle of the present utility model, because being detouchable, an end of its Shock absorber and bicycle flexibly connect, when needed, one end of Shock absorber can be unclamped from bicycle, make back vent five-way triangle rotation forward around the shaft, and fix, thereby realize that the folding of bicycle park by the fixedly fetching on spacer and the batter post.The utility model is to improve to form on the basis of original anti-vibration bicycle, and is simple in structure, easy to use, has good economic benefits and social benefit.

The specific embodiment

As shown in Figure 1, in an embodiment of the present utility model, anti-vibration bicycle comprises vehicle frame, front and rear fork and front and back wheel, described vehicle frame comprises A-pillar 11 and the preceding triangle that is made of spreader 201, batter post 202 and rear column 203, between the lower end of preceding triangle and back vent 31, rotating shaft five-way 8 is installed, between rear column 203 and back vent 31, Shock absorber 4 is installed.

The upper and lower side of Shock absorber 4 all has axis hole, and its upper end fixes with rear column 203 by last shock-absorbing fetching 1, and its lower end is by shock-absorbing fetching 5 and back vent 31 fix down.As shown in Figure 4, the bottom of following shock-absorbing fetching 5 is a bridge chip architecture 51, and this bridge chip architecture 51 is fixed on the back vent 31 in the mode of welding; The top of following shock-absorbing fetching 5 is the slotted vane structure that has axis hole, the lower end of Shock absorber 4 can be contained in wherein, and realize that by axis hole and pin rotating shaft is connected.As shown in Figure 3, the front portion of last shock-absorbing fetching 1 is fixed on the rear column 203 in the mode of welding, its rear portion is the slotted vane structure that has axis hole, also be provided with iron plate 2 in the arc surfaced that plays the role of positioning above the axis hole between slotted vane, the upper end of Shock absorber 4 can be contained in the cambered surface of slotted vane and interior iron plate 2, and by axis hole with draw pin 3 to realize that detouchables flexibly connect.As shown in Figure 5, an end that draws pin 3 is circular, is convenient to the user and pulls and supports; Draw the other end of pin 3 to have hoodle mechanism.

As shown in Figure 1, when the deployed condition of bicycle, will draw pin 3 to pass the axis hole of shock-absorbing fetching 1 and Shock absorber 4 upper ends, draw the hoodle mechanism on the pin 3 to make the hoodle projection, block axis hole, thereby Shock absorber 4 is fixed in the slotted vane of shock-absorbing fetching 1, lay parking pin 6 and prop up bicycle.At this moment, Shock absorber 4 and rotating shaft five-way 8 only play the shock-absorbing effect of common anti-vibration bicycle.

As shown in Figure 3, be fixed with the spacer 7 in tape spool hole at the end of captiveing joint of rotating shaft five-way 8 and back vent 31, spacer 7 both can be fixed on the rotating shaft five-way 8, also can be fixed on the back vent 31.Also be provided with fixedly fetching 9 on batter post 202, fixedly the top of fetching 9 is fixed on the batter post 202 in the mode of welding, and its underpart is the slotted vane structure that has axis hole, spacer 7 can be contained in the slotted vane structure, and by drawing pin to fix.In the present embodiment, the axis hole of the axis hole size of spacer 7 and fixedly fetching 9 and the upper end of Shock absorber 4 and last shock-absorbing fetching 1 is measure-alike, like this, at stationary positioned sheet 7 with fixedly during fetching 9, just can use identical with the upper end of fixing Shock absorber 4 and last shock-absorbing fetching 1 pin 3 that draws.

As shown in Figure 2, when the needs folding bicycle, parking pin 6 is left ground, and the pin 3 that draws that will go up between shock-absorbing fetching 1 and the Shock absorber 4 is pulled out; Improve bicycle, then Shock absorber 4 unclamps from bicycle, back vent 31 five-way 8 around the shaft rotates to batter post 202, and the spacer 7 on the rotating shaft five-way 8 enters in the slotted vane structure that is fixed on the fixedly fetching 9 on the batter post 202, and inconsistent and stop operating with fixing fetching 9; To draw pin 3 to pass spacer 7 and fixedly in the axis hole in the fetching 9, draw the hoodle projection on the pin 3, make spacer 7 and fixedly fetching 9 fix, thereby bicycle is fixed on the folding position; Lay parking pin 6 and prop up bicycle.
