Description

A kind of bicycle saddle Shock absorber

The utility model relates to a kind of bicycle accessory, especially the shock absorbing apparatus of bicycle saddle.

Common bicycle, the shock-absorbing of its saddle are only realized from the extension spring and the stage clip that are arranged on the saddle, make and ride energy damping vibration when sailing bicycle.But owing to all be rigidly connected at gravity direction between saddle and vehicle frame, vehicle frame and the wheel, and owing to be subjected to the restriction in saddle structure and space, its shock-proof effect is relatively poor, can not satisfy the requirement of bicycle saddle shock-absorbing.Especially in the suburb or long-distance riding when sailing, can make and ride the people who sits bicycle and feel very ill, the shock-absorbing problem of bicycle saddle is still waiting further solution.

The purpose of this utility model is to provide a kind of shock absorbing apparatus that is built in the cycle frame saddle tube, setting up one between saddle and vehicle frame flexibly connects, supporting existing common bicycle saddle, vibrations when further cushioning by bike improve the situation of present ordinary bicycle saddle shock-proof device weak effect.

For achieving the above object, the utility model is provided with sleeve in cycle frame saddle tube, and sleeve is through hole, and the lower end is provided with the retaining mouth; In sleeve, be provided with spring, abutment sleeve and Saddel receiver axle.Spring perch is equipped with at the two ends of spring, and lower spring cup is spacing on the retaining mouth of sleeve lower end, and abutment sleeve tightly is enclosed within the upper end of sleeve; Abutment sleeve axially have two through holes.The lower end of Saddel receiver axle is provided with two slide bars, and jack rod sleeve can owing to use two Slide bar structures, can be realized the radial location of Saddel receiver axle along axially the moving up and down of abutment sleeve in the through hole of abutment sleeve; Back-up ring is equipped with in the lower end of slide bar, prevents that slide bar from being transferred to abutment sleeve; The lower end of slide bar is pressed on the upper spring seat of spring.Principle of work of the present utility model is, the sleeve of Shock absorber by banding in the saddle tube of cycle frame, saddle is installed in the upper end of Saddel receiver axle, and the Saddel receiver axle can move up and down in abutment sleeve, and the slide bar of riding Saddel receiver axle when sitting is pressed on the spring; When bicycle running is shaken, pass to saddle again behind the spring shock absorption of the shaking force of vehicle frame in being contained in sleeve, realize the further shock-absorbing of bicycle saddle.

Use the utility model,, the shock-proof effect of bicycle saddle is obviously increased for bicycle saddle increases a Shock absorber.Of the present utility model simple and compact for structure, easy for installation, cost is low; And Shock absorber is arranged in the vehicle frame of bicycle, do not influence the structure and the usage condition of existing bicycle.

Fig. 1 is structure of the present utility model and scheme of installation.

Below in conjunction with accompanying drawing structure of the present utility model is described in further detail.

The utility model structurally includes sleeve 1, spring 2, abutment sleeve 3 and Saddel receiver axle 4; Sleeve 1 is through hole, and the lower end is provided with retaining mouthful, and sleeve 1 is enclosed within the saddle tube 6 of cycle frame 5 and by banding; Lower spring cup 7 and upper spring seat 8 are equipped with in the two ends of spring 2, are inserted in sleeve 1, and lower spring cup 7 is limited on the retaining mouth of sleeve 1 lower end; Abutment sleeve 3 tightly is enclosed within the upper end of sleeve 1, and locatees with screw 9; Abutment sleeve 3 axially be provided with two through holes; There are two slide bars 10 lower end of Saddel receiver axle 4, and slide bar 10 is enclosed within the through hole of abutment sleeve 3, can move up and down along the axis of abutment sleeve 3; Back-up ring 11 is equipped with in the lower end of slide bar 10, and is pressed on the upper spring seat 8.Saddle 12 is fixed on the upper end of Saddel receiver axle 4.
