Description

The saddle adjustment structure of bicycle

Technical field

The utility model relates to a kind of saddle adjustment structure of bicycle, specifically, relates to a kind of saddle adjustment structure that can adjust seat position and elevation angle angle.

Background technology

As shown in Figures 1 and 2, be existing have the bicycle use seat of angle and position regulating function and the joint construction of car body, wherein, seat (among the figure indicate) in the bottom at least and show two

poles

10,10 places are provided with a contiguous block 20 two poles, the vehicle frame of bicycle (not indicating among the figure) has then extended upward a pipe 30, the top of present pipe 30 is provided with a joint 40 that engages with contiguous block 20 formations, see through in addition one first bolt 50 with contiguous block 20 and joint 40 interlocking mutually, combine with a locking of managing 30 thereby constitute seat.

Wherein, contiguous block 20 is with pole 10 clippings by upper and lower intermediate plate 21,22, and on upper and lower intermediate plate 21,22, be provided with the through hole 23 that passes through for

first bolt

50,40 of its joints are provided with an interlocking hole 41 that supplies first bolt 50 to wear, being provided with a screw 24 in addition above the intermediate plate on the contiguous block 20 21 is spirally connected for first bolt 50, when locking with screw 24 with first bolt 50, can pole 10 be clamped by upper and lower intermediate plate 21,22, and together with contiguous block 20 and joint 40 are clamped, with the top of the pipe 30 of really the seat locking being present.

In addition, be to be the curved arc shape in the joint place of joint 40 and contiguous block 20, and be provided with shaggy tooth 60 at the binding face of joint 40 and contiguous block 20 respectively,, reach the purpose of adjusting chair angle in order to via changing the corresponding engage position of contiguous block 20 with joint 40.

But above-mentioned structure design is when only needing to adjust chair angle, and it need discharge the clamping action of 20 pairs of poles 10 of contiguous block simultaneously, and can make pole 10 loosening with contiguous block 20, and then changes the front and back position of seat; Equally, when seat only need be adjusted front and back position, the snap action that it also discharges between contiguous block 20 and the joint 40 simultaneously can make contiguous block 20 loosening with joint 40, and then changes the angle of seat, and the practical function of out of reach expection.

The utility model content

The technical problem to be solved in the present invention is, for overcoming outside the deficiencies in the prior art, and provides a kind of saddle adjustment structure of bicycle.

The technical solution adopted for the present invention to solve the technical problems is: the saddle adjustment structure that a kind of bicycle is provided, its joint has an interlocking plate that is the curved arc shape, interlocking plate two ends are provided with lug, two lugs are provided with perforation and penetrate for two first bolts, contiguous block is provided with the perforation that passes for each first bolt, and utilize adjustment part to lock mutually with each first bolt, and with joint and the mutual interlocking of contiguous block, with locking effect contiguous block is suppressed towards joint, and can be reached the purpose of adjusting chair angle via regulating the position of contiguous block on the interlocking plate via adjustment part and each bolt; And, this contiguous block then utilizes two locking blocks and one second bolt that two poles are located, and second bolt is penetrated by the locking block of contiguous block one end earlier, fixes with the locking block of the contiguous block other end again, so that two poles are positioned on the pipe, then can adjust the front and back position of seat by discharging second bolt.

In the saddle adjustment structure of bicycle of the present utility model, the curved arc face of described interlocking plate is provided with an arcuation body with perforation, and the binding face of contiguous block and interlocking plate is provided with the slotted eye that can pass for the arcuation body.

In the saddle adjustment structure of bicycle of the present utility model, described slotted eye is slightly larger than the arcuation body, and described arcuation body can be in the slotted eye activity.

In the saddle adjustment structure of bicycle of the present utility model, described adjustment part forms the arcuation face with the perforation binding face.

In the saddle adjustment structure of bicycle of the present utility model, described each locking block is provided with the through hole that can supply second bolt to pass, and the through hole of this side locking block then is provided with the thread with the second bolt bolt.

In the saddle adjustment structure of bicycle of the present utility model, described each locking block is provided with the through hole that can supply second bolt to pass, and the through hole of this side locking block then is provided with the nut with the second bolt bolt outward.

In the saddle adjustment structure of bicycle of the present utility model, be lined with at least one washer between described first bolt and this joint.

The saddle adjustment structure of practical bicycle of the present utility model has following beneficial effect: when adjusting the angle of seat via release first bolt, its contiguous block and pole are still kept firm clipping power, and are unlikely the front and back position of any change seat; Otherwise when second bolt that discharges contiguous block was adjusted the front and back position of seat and vehicle frame, the angle of seat also was unlikely any change, and seat was had more be convenient to the function of individual event angular adjustment or the adjustment of individual event front and back position.The utlity model has advantages such as steadiness is good, action is determined.
