The specific embodiment

See also Fig. 1, Figure 1A and shown in Figure 2, bicycle saddle cushion fixed sturcture of the present utility model, by comprising: a pedestal 2, two is that the circular slide 3 that is oppositely arranged, folder cover 4, enclosing cover 5 and a securing arrangement 6 are formed; Wherein:

Described pedestal 2 is to be long block to be installed in bicycle seat pole 21 upper ends towards the place ahead, and its and arranged on left and right sides is to be respectively equipped with long guide groove 22, and long guide groove 22 central authorities are provided with a long guide hole 23;

Described two circular slides 3, be to be the left and right side that is located at pedestal 2 relatively and respectively, its central authorities are provided with a perforation 31, and a side of its corresponding pedestal 2 is to establish to cooperate the slide block 32 of pedestal 2 long guide grooves 22, and its opposite side is then outwards established with several engaging tooths 33 radially from central perforation 31;

Described two folders cover 4, be to be to divide circular slide 3 outsides that are located at pedestal 2 left and right sides relatively, its central authorities are provided with a perforation 41, its corresponding circle seat slide 3 sides are outwards to establish radially with several engaging tooths 42 from central perforation 41, the adjustment location that cooperates with set also radially engaging tooth 33 on the circular slide 3 and rotate, folder cover 4 opposite side epimeres and is provided with a long groove 43, and described opposite side sets to the concave from central perforation 41 outer peripheral edges and one locatees groove 44;

Described two enclosing covers 5, be to be to divide relatively to be located to press from both sides to cover 4 outsides, its central authorities are provided with a perforation 51, the epimere that its corresponding clip covers 4 sides is to be provided with a long groove 52, and make described long groove 52 and be located at folder and cover long groove 43 corresponding matching on 4, it then establishes a location bead 53 to evagination from central perforation 51 outer peripheral edges, and is located at the detent 44 that covers on 4 of folder and aligns nested location;

Described lock member 6, it is made up of screw rod 61 and nut 62, and make screw rod 61 oneself wherein pass the perforation 51 that is located at enclosing cover 5 central authorities in an enclosing cover 5 outsides, be located at corresponding described side and press from both sides the perforation 41 of covering 4 central authorities, be located at the perforation 31 of the circular slide of corresponding described side 3 central authorities, be located at the long guide hole 23 of the long guide groove of pedestal 2 22 central authorities, be located at the perforation 31 of the circular slide of pedestal 2 opposite sides 3 central authorities, be located at pedestal 2 opposite sides and press from both sides the perforation 41 of covering 4 central authorities, be located at the perforation 51 of pedestal 2 opposite side enclosing covers 5 central authorities, last and nut 62 is sealed, reaching can be with pedestal 2, circular slide 3, folder cover 4 with enclosing cover 5 composition one.

Rely on said structure to be formed, see also Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 4 A, Fig. 5, shown in Fig. 6 A and Fig. 6 B, the seat cushion (not drawing) that is provided with two parallel strut bars 7 when the bottom is desired and is plugged on seat bar 21 upper ends cycle frame seat pipe (not drawing) in when making up, just the screw rod 61 of lock member 6 can be unscrewed a segment distance with nut 62, be central authorities with two strut bars 7 of seat cushion with the pedestal 2 of seat bar 21 upper ends then, two strut bars 7 are set in pedestal 2 both sides respectively, and cover 4 and the set long groove 43 of enclosing cover 5 respective side epimeres by being located at folder, in 52, and once again the screw rod 61 of lock member 6 is done locking slightly with nut 62, then the rider can according to individual itself need with custom, except cover the radially set and engaging tooth 33 that is meshed of work of 4 correspondence positions to circular slide 3 and folder, 42 adjustment that rotate, and adjust on the desired seat cushion, outside the lower angle, particularly, when the distance of displacement is adjusted before and after desire is done seat cushion, its whole seat cushion adjustable front and back translocation distance, front position that length can be done except seat cushion bottom strut bar 7, outside the translocation distance of rearmost position, more, pedestal 2 designs towards the place ahead owing to being long block, be positioned at a left side and increase, the translocation distance of the length A of the set long guide hole 23 of right both sides long guide groove 22 central authorities is (as Fig. 6 A, shown in Fig. 6 B), and make the slide block 32 of the set cooperation pedestal 2 long guide grooves 22 of circular slide 3 corresponding pedestal 2 sides, thereby can adjust along the distance that set long guide hole 23 length A of pedestal 2 long guide groove 22 central authorities are done between front position to rearmost position, and make whole seat cushion can increase the translocation distance of a segment base seat 2 set long guide hole 23 length A especially again, with regard to the person that desires to drive the bicycle, be not quite similar in height because of everyone, driving posture also is not quite similar, the position habit that is sitting on the seat cushion also all is not quite similar down, can provide in a big way a translocation distance to provide and use the effect that promotes with the Practical Performance of selecting.

In addition, see also shown in Fig. 7 and Fig. 7 A, at two enclosing covers 5 from its central perforation 51 outer peripheral edges to location bead 53 peripheries that evagination is established, can be nested with spring 54 more respectively, when location bead 53 be located at press from both sides cover 4 detent 44 align nested after, further the bottom is provided with the seat cushion (not drawing) and the 21 upper ends combination of seat bar of two parallel strut bars 7, and when the screw rod 61 of lock member 6 unscrewed a segment distance with nut 62, the elastic force that can rely on described spring 54, with enclosing cover 5 extrapolations, make to be located at enclosing cover 5 and to press from both sides and cover the set long groove 52 of 4 respective side epimeres, 43 thereby keep an intersegmental distance, provide two strut bars 7 that are located at the seat cushion bottom can relatively easily be set in pedestal 2 both sides reasons and be located at folder and cover 4 and the set long groove 43 of enclosing cover 5 respective side epimeres, the convenient effect of 52 in-to-ins.

Please consult again shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 4 A, the pedestal 2 that seat bar 21 cooperates the upper end to set firmly can be long block design down, also seat bar 21 stage casings 211 are the design of flats relatively towards the place ahead, and different all adopting with pipe in general seat bar integral body made, order seat bar 21 hypomeres 121 outer peripheral edges then are nested with a circular locating bush 213 again and provide with cycle frame seat pipe box insert group and close, provide bicycle to drive in the process, can reach and to reduce the windage effect because of seat bar 21 stage casings are the flats design down.

More than explanation is just illustrative for the utility model, and it is nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited, can make many modifications, variation or equivalence, but but all will fall within the claim restricted portion of the present utility model.
