Abstract

A folding bicycle saddle height adjustment device comprise a seat tube fixed on a bicycle frame, a seat bar inserted into the seat tube movably, and a fixed assembly fixed on the upper end of the seat tube for locking the seat tube and the seat bar. A saddle is fixed on the seat bar. A guide slot extending along the lengthwise direction of the seat bar is arranged in the outer surface of a side wall of the seat bar. A position limiting block inserted into the guide slot is arranged on the fixed assembly. Compared to the prior art, The device uses the position limiting block to cooperate with the guide slot in the seat bar to effectively prevent the seat bar from rotating, so that the saddle is prevented from rotating during height adjustment, and height adjustment processes of the saddle are simplified. Thus the device facilitates usage. Meanwhile, through cooperation between a position limiting baffle sheet and the position limiting block, it can be determined precisely if the height of the saddle is adjusted in place through resistance to pulling the seat bar with hands, so that the device further facilitate usage.

The specific embodiment

Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:

As shown in Figure 1,2,3, 4, for a kind of folding bicycle saddle height setting device of the present utility model, it comprises sits pipe 20, seatpost 10, clip 30 and spanner 40, wherein, sitting pipe 20 is fixed on cycle frame, seatpost 10 is managed in 20 by the seat that is inserted into of sitting the opening activity of managing 20 tops, and this seatpost 10 is managed a telescoping mechanism of 20 formations with sitting, and the saddle of bicycle is fixed on the upper end of seatpost 10.Clip 30 is fixed on the upper end of sitting pipe 20, concrete, to sit pipe 20 upper ends and be provided with one along its axially extended pretension groove, the external diameter of sitting pipe 20 is slightly larger than the internal diameter of clip 30, utilize the deformation of clip 30 upper ends with pretension groove position, clip 30 is fixed on to the upper end of sitting pipe 20, spanner 40 is for applying pretension or clip 30 being unclamped to clip 30, thereby realize seat pipe 20 and be in locking or the relative state that can slide with seatpost 10, concrete is, one end of spanner 40 has an eccentric cam 41, the other end forms a struck side, two free ends of clip 30 extend laterally and form respectively a plate-like portion 31, in two plate-like portions 31, cross-under has a pull bar 42, one end of this pull bar 42 is provided with the positive stop that is positioned at one of them plate-like portion 31 outside, eccentric cam 41 coordinates with another plate-like portion 31 lateral surfaces, in the time that needs are locked, stir spanner 40, the salient of eccentric cam 41 is rotated and top pressing board shape portion 31, now, the internal diameter of clip 30 diminishes, by seatpost 10 and 20 lockings of seat pipe, reversion spanner 40, can unclamp seatpost 10 and sit pipe 20.

The side outside face of seatpost 10 is provided with a guide groove 11 extending along its length direction, on the medial surface of clip 30, be provided with a limiting stopper 32, this limiting stopper 32 is consistent with the shape of guide groove 11, and limiting stopper 32 is inserted in guide groove 11, because limiting stopper 32 and guide groove 11 are worked in coordination, the seatpost 10 making along axially with respect to sit pipe 20 slide time, it can not rotate around the center shaft of self, in slip seatpost 10 to adjust when saddle height, due to the position-limiting action of limiting stopper 32 and guide groove 11, saddle can not rotate, thereby simplify the process that saddle is adjusted, easy to use, user is without the rotational angle of considering saddle, only need to pull seatpost 10 just can reach the object of adjusting saddle height.

For further easy to use, in seatpost 10, the side that is positioned at guide groove 11 is provided with multiple mounting grooves 12, the plurality of mounting groove 12 is arranged along the length direction of seatpost 10, an inner detouchable of mounting groove 12 is fitted with a spacing catch 13 therein, the plug-in mounting position of this spacing catch 13 is positioned at the below of clip 30, in the time upwards pulling seatpost 10 that spacing catch 13 is moved to contact with limiting stopper 32 with limiting stopper 32 belows, limiting stopper 32 stops spacing catch 13 upward movements, now, seatpost 10 can not continue upwards to pull.In use, spacing catch 13 is inserted in a predetermined mounting groove 12, in the time upwards pulling seatpost 10 that spacing catch 13 is contacted with limiting stopper 32, proof seatpost 10 is adjusted to the right place, now, the height of saddle is just in time applicable to riding, therefore, user can be as required, select the spacing catch 13 of prize to be inserted in certain mounting groove 12, be applicable to riding with the height that makes the saddle after adjustment, this adjustment mode is compared the existing mode of determining saddle height by scale mark, has advantage fast, easily.Above-mentioned multiple mounting grooves 12 can be equally spaced arrangements.

Sit pipe 20 inside and be fixed with clamping cover 50, this clamping cover 50 is enclosed within seatpost 10, on clamping cover 50, be provided with one along its axially extended fluting 51, make in clip 30 extruding, there is deformation in clamping cover 50, increased clamping force, clamping cover 50 can select plastic material to make, and can avoid seatpost 10 to be worn by actv..

In technique scheme of the present utility model, adopt clip 30 and spanner 40 to form the locking that a fixation kit is realized seatpost 10 and sat pipe 20, certainly, the locking that also can utilize the fixation kit of other version to realize seatpost 10 and sit pipe 20.

To one skilled in the art, can be according to technical scheme described above and design, make other various corresponding changes and deformation, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
