Description

Bike saddle adjustment structure

Technical field

The utility model relates to the bicycle field, refers in particular to a kind of bike saddle adjustment structure.

Background technology

Be the connecting structure of being used always between the seat of existing bicycle and the car body as shown in Figure 1, its seat (among the figure indicate) is in the bottom at least and show two poles 10 ', locate to be provided with a link block 20 in two poles 10 ', the vehicle frame of bicycle (not indicating among the figure) then is to extend upward a vertical rod 30 ', be provided with one at vertical rod 20 tops and be used for the joint 40 that engages with link block 20, in addition by a bolt 50 with link block 20 and joint 40 interlocking mutually, by and the formation seat combines with the locking of vertical rod 30 '.

Wherein, link block 20 by upper clamping piece 21, lower clamping piece 22 with pole 10 ' clipping, and on upper clamping piece 21, lower clamping piece 22 and joint 40, be provided with the through hole that passes through for bolt 50, above the upper clamping piece 21 of link block 20, be provided with a nut 23 with bolt 50 bolts in addition; When bolt 50 during with nut 23 lockings, promptly utilize upper clamping piece 21, lower clamping piece 22 that pole 10 ' is clamped, and also clamped together with link block 20 and joint 40, reach seat is fixed on vertical rod 30 ' apical end.

In addition, be the curved arc shape, and be provided with shaggy tooth 60 ' at the binding face of joint 40 and link block 20 respectively, so that, reach the purpose of regulating chair angle by changing the mode of link block 20 and joint 40 opposite positions in the joint place of joint 40 and link block 20.But this structure design will make the adjusting action of seat be tending towards complicated loaded down with trivial details, discharge the clamping action of 20 pairs of poles 10 ' of link block especially simultaneously, can make between pole 10 ' and the link block 20 loosening fully, and then the front and back position of change seat; Same, when seat need be adjusted front and back position, also must discharge the snap action between link block 20 and the joint 40, also can make between link block 20 and the joint 40 loosening fully, change chair angle on the contrary, so that this connecting structure practicality and ease of use are neither as expection is desirable.

The utility model content

Technical problem to be solved in the utility model is: a kind of bike saddle adjustment structure is provided, and its structure is firm, angular adjustment is easy and simple to handle, and in adjusting the chair angle process, can not change the seat front and back position arbitrarily.

The further technical matters to be solved of the utility model is: a kind of bike saddle adjustment structure is provided, and it can not change chair angle arbitrarily in adjusting seat front and back position process.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of bike saddle adjustment structure, the coupling sleeve, a ring piece, the bolt and that comprise the rod end of being located at bicycle compress part, and described coupling sleeve is provided with a horizontal hole and that wears and is through to the bolt penetration hole that wears the hole; Described ring piece is one and is used for the hollow ring circle body that combines with the seat of bicycle that it is located in wearing in the hole of coupling sleeve, and the corresponding slotted eye that is provided with a perforation to the hollow part; Described bolt radially is located between coupling sleeve and the ring piece in the mode of passing bolt penetration hole and slotted eye, and is limited in rotating in the bolt penetration hole of coupling sleeve; Described compress part be located at the ring piece the hollow part, and with the bolt bolt; When bolt with compress part when locking mutually, make to compress part, ring piece and coupling sleeve three and closely overlay, constitute interference between ring piece and the coupling sleeve by compressing part, the check ring piece rotates and the fixed seat elevation angle; When unclasping bolt, i.e. release compresses part to the interference between ring piece and the coupling sleeve, and the ring piece can rotate the angle of adjusting seat in the slotted eye restricted portion.

Wherein, the two ends of this ring piece are respectively equipped with end cap, by described two end cap two poles of bicycle seat bottom are distinguished the two ends of clampings at this ring piece, and bicycle seat is assembled on the ring piece.

The beneficial effects of the utility model are: the utility model is when unclamping bolt and carry out the angular adjustment of seat, because seat is fixed on the ring piece, and can not change the front and back position of seat; And the ring piece when the end cap of trip ring piece carries out the adjustment of seat front and back position, can not change the angle of seat owing to can't rotate.

The specific embodiment

To shown in Figure 4, the utility model provides a kind of bike saddle adjustment structure as Fig. 2, consists essentially of a coupling sleeve 71, ring piece 72, bolt 73 and one and compresses part 74.

Wherein, coupling sleeve 71 is located at vertical rod 30 tops of bicycle, and coupling sleeve 71 is provided with one and horizontal wear hole 711 and one and be through to the bolt penetration hole 712 that wears hole 711; 72 of pieces of ring are used for combining with the seat of bicycle, and ring piece 72 is one and is located in the hollow ring circle body that coupling sleeve 71 wears hole 711, the corresponding slotted eye 721 that is provided with a perforation to the hollow part on ring piece 72; Above-mentioned bolt 73 promptly radially is located between coupling sleeve 71 and the ring piece 72 in the mode of passing bolt penetration hole 712 and slotted eye 721, and is limited in rotating in the bolt penetration hole 712 of coupling sleeve 71; As for compress 74 of parts be located at the ring piece 72 the hollow part, and with bolt 73 bolts.

When bolt 73 with compress part 74 mutually during locking, to make and compress part 74, ring piece 72 and coupling sleeve 71 threes closely overlay, add that bolt 73 is limited on the coupling sleeve 71, be screwed onto on the bolt 73 and compress part 74, therefore can constitute the interference that encircles between piece 72 and the coupling sleeve 71 by compressing part 74, check ring piece 72 rotates, and reaches the purpose at the fixed seat elevation angle; In the specific implementation, compress both positions that fits of part 74 and ring piece 72 and also can be respectively equipped with and constitute ingear shaggy tooth 60, utilize the engagement of shaggy tooth 60, strengthen the lock of ring piece 72 effect of pulling.

Otherwise, when unclasping bolt 73, as shown in Figure 5, can discharge the interference that compresses between part 74 pairs of rings piece 72 and the coupling sleeve 71, allow ring piece 72 be able to rotate in slotted eye 721 restricted portions, the handled easily person adjusts the angle of seat, and in the process of adjusting chair angle, can not change the front and back position of seat arbitrarily, effectively solve existing bicycle seat when adjusting angle, can change the problem of seat front and back position simultaneously.

In addition, as shown in Figures 2 and 3, the two ends of ring piece 72 also are respectively equipped with end cap 75, utilize these two end caps 75 that two poles 10 of seat are distinguished the two ends of clampings at ring piece 72, and ring piece 72 is combined with seat; In the specific implementation, ring piece 72 also is provided with the recessed rail 76 that embeds for pole 10 with position that end cap 75 covers mutually, utilize again one group wear locking bar 77 with two end caps 75 simultaneously towards 72 lockings of ring piece, and reach the purpose that pole 10 clippings are fixed.

Otherwise,, can allow pole 10 slide, and then adjust the front and back position of seat along recessed rail 76 as long as two end caps 75 are loosened; Same, in the process before and after adjusting seat, can not change the angle of seat arbitrarily, effectively solve existing bicycle seat when adjusting front and back position, can change the problem of chair angle.
