Abstract

The utility model discloses a shock absorber of bicycle, which is composed of a bicycle frame, a bicycle front fork and a back supporting frame. The utility model is characterized in that the right and the left risers of the bicycle front fork are divided into an upper section, a lower section and a lifting rod; the lower end of the upper section is provided with an outer screw and inner part of the upper section is in a hollow shape. The lower section is also in a hollow shape; a round table is arranged on the lower section near an upper part; the round table is provided with a hole through which the lifting rod can pass; the lower end of the lower section is provided with the outer screw; the lifting rod sheathed with a spring is penetrated into the round table; the end of the lifting rod which passes through the round table is locked by a nut; the lower end of the lower section is provided with a movable end cover; a screw arranged in the end cover is matched with the outer screw of the lower end of the lower section. The structure of the back supporting frame is the same as that of the bicycle front fork. The utility model has the advantages of simple structure and obvious vibration damping effect; when the riders ride a bicycle, the fatigue is reduced; the service life of the components is prolonged because of the function of a damping device; the safety factor of the rider is improved.

Description

The bicycle shock-absorption device

The utility model relates to bicycle, is meant that especially a kind of sleeve and spring of utilizing absorbs the bicycle shock-absorption device that the vibration of bicycle in the process of riding reaches vibration damping.

Present common bicycle, comprise that people usually ride the common car of usefulness, the fancy car, mountain bike, common sport car etc., the vibration that produces in riding mainly reduces by the tire of sufficient gas and several extension springs below the vehicle seat and absorbs, the absorption of this kind side examination and effectiveness in vibration suppression and unsatisfactory, the vibration that produces in riding is to the people, be still bigger to whole vehicle frame, the vibration that produces so that ride for a long time, loosening to the part that vehicle frame itself uses, damage, people's shoulder etc. is partly produced the fatigue of aching, the bicyclist is not felt well, sometimes also can be loosening because of vehicle part, damage causes danger to the rider.

The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of bicycle shock-absorption device of providing.

The purpose of this utility model is achieved in that mainly and is made of vehicle frame, car front fork, bracket of rear mounting etc. that it is characterized in that: the left and right sides standpipe of front fork is divided into epimere, hypomere, portable bar, and the lower end of epimere is provided with outside thread, and interior is hollow tubular; Hypomere also is a hollow tubular, and be provided with a round platform near upper end, having hole can hold portable bar in the round platform passes, the lower end part of hypomere is provided with outside thread, being built-in with the portable bar that is with spring penetrates to round platform, passing drawing together of round platform part has nut locking on the rod end head, the lower end of hypomere is provided with the end cap of an activity, is provided with screw thread in the lid and matches with the outside thread of hypomere lower end; The structure of bracket of rear mounting is identical with front fork.

Advantage of the present utility model is simple in structure, and effectiveness in vibration suppression is obvious, and the rider is when riding, and tired sensation obviously reduces, and vehicle body is also because the effect of shock attenuation unit, the ILS of each parts, and rider's safety factor also is improved.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an assembling scheme drawing of the present utility model.

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

As shown in Figure 1, front fork left and right arms structure unanimity of the present utility model, mainly by standpipe epimere 1, hypomere 2, portable bar 3, combine, the lower end of standpipe epimere 1 is provided with outside thread 4, match with the upper end negative thread 5 of hypomere 2, be combined into a complete standpipe, the last intersegmental part of hypomere 2 is provided with a round platform 6, there are a hole 12 ccontaining portable bars 3 upper ends 10 to pass in the round platform 6, round platform is equipped with spring 76 times, and the lower end of hypomere 2 is provided with outside thread 8, matches with the negative thread of hypomere end cap 9, spring 7 is contained between the round platform 6 and the middle top flat 13 of portable bar of hypomere 2, portable bar 3 upper ends are provided with outside thread 10, and there is top flat 13 centre, the front axle socket of lower end and wheel.

The utility model when assembling as shown in Figure 2, portable bar 3 was gone here and there end cap 9 from bottom to top, load onto top flat 13 backs and insert hypomere 2, pass spring 7, round platform 6 and use nut 11 lockings at the upper port place of hypomere 2, end cap 9 is tightened mutually with the lower end screw thread 8 of hypomere 2, utilizes screw thread 4,5 to screw standpipe epimere 1 and hypomere 2 then and gets final product.

In riding, tire is vibrated, promote portable bar 3 upward movements, top flat 13 is holddown spring 7 upwards, the vibratory force that makes progress is passed to spring 7, make standpipe absorb under the vibration and keep not upward movement substantially, on the handlebar of shaking hands before promptly vibratory force can not being delivered at spring 7, the cyclist just can not be subjected to having vibrated top power upwards like this, has reached the purpose of vibration damping.

The vibration-proof structure of bracket of rear mounting is consistent with the vertical tube of front fork structure, gives spring with the transfer of vibration of trailing wheel equally, makes it absorb vibration, and does not transfer vibrations on the vehicle frame of whole back, also vibration can not passed to people's body part then, has reached the purpose of vibration damping.

Claims

1, a kind of bicycle shock-absorption device mainly is made of vehicle frame, car front fork, bracket of rear mounting etc., and it is characterized in that: the left and right sides standpipe of front fork is divided into epimere, hypomere, portable bar, and the lower end of epimere is provided with outside thread, and interior is hollow tubular; Hypomere also is a hollow tubular, and be provided with a round platform near upper end, having hole can hold portable bar in the round platform passes, the lower end part of hypomere is provided with outside thread, being built-in with the portable bar that is with spring penetrates to round platform, passing drawing together of round platform part has nut locking on the rod end head, there is the end cap of drawing together the lower end of hypomere, is provided with screw thread in the lid and matches with the outside thread of hypomere lower end; The structure of bracket of rear mounting is identical with front fork.
