Abstract
Bike saddle chair height adjustment, all being square a socket joint section of thick bamboo and plug tube including the cross -section, setting gradually the supported hole of the high difference of a plurality of groups on the socket joint section of thick bamboo wall, every group supported hole all includes two support square holes and two support round holes, and it has the square bolt to support the square hole matching, and it has the cylinder bolt to support the round hole matching, and the square bolt includes that the cross -section is square bolt midbody, sets up the screw hole that link up on the bolt midbody, cylinder bolt and screw hole threaded connection phase -match, the flexible layer of cladding on the plug tube lateral wall, plug tube pegs graft when stretching into in the socket joint section of thick bamboo, elastic layer and socket joint section of thick bamboo inner wall tight fit. This bike saddle chair height adjustment square bolt and cylinder bolt form the cross and support, are used for supporting plug tube with plug tube bottom counterbalance, the flexible layer of cladding on the plug tube lateral wall just so makes plug tube can not deviate from a socket joint section of thick bamboo easily simultaneously, has kept the connection stability of the two.
Description
Technical field
The utility model belongs to bicycle art, more particularly, to a kind of bicycle seat height adjuster.
Background technology
The height of bicycle seat is typically adjusted by seatpost structure, and existing seatpost generally comprises the company being connected with seat
Extension bar and and the combination bar that is connected of vehicle frame, connecting rod and fixation is clamped by fixture with reference to bar, when needing regulation high
When spending, unclamp fixture and be attached bar and combine the adjustment of bar relative position, regulation finishes rear clamping device.This kind of structure
Bar is attached using frictional force and combine the fixation of bar, during cycling, it is easy to which offsets in height occurs, so that
Height of seat regulation must not be infrequently carried out, bicyclist's Experience Degree is poor.
Utility model content
In view of this, the utility model is directed to a kind of bicycle seat height adjuster, to solve existing seat
Easily there is offsets in height in height adjusting structure, need to carry out the problem of frequent adjustment work.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in：
The bicycle seat height adjuster, including section be square socket joint cylinder and grafting cylinder, socket joint cylinder with
Bicycle rack is fixedly connected, and grafting cylinder one end is connected with vehicle seat, the grafting cylinder other end can grafting stretch into the openend of socket joint cylinder,
The socket joint cylinder is disposed with some groups of highly different supported holes on the barrel of openend, and every group of supported hole includes
Two coaxial lines and axis perpendicular to socket joint cylinder axis support square hole and two coaxial lines and axis perpendicular to socket joint cylinder axle
The supporting circular holes of line, this two support two supporting circular holes of square hole and this it is highly consistent, and this two support square hole axis and
Two supporting circular holes axis perpendiculars；
The support square hole matching has square bolt, and supporting circular holes matching has cylindrical bolt, and square bolt is in including section
Square bolt intermediate, offers the screwed hole of insertion on bolt intermediate, cylindrical bolt is threadedly coupled phase with screwed hole
Match somebody with somebody；
Elasticity layer is coated on the wall of grafting cylinder side, grafting cylinder grafting is stretched into when in socket joint cylinder, elastic layer and socket joint cylinder
Inwall tight fit.
Further, the grafting cylinder bottom is provided with cushion pad.
Further, the square bolt also includes nuts and bolted connection, square nuts and columned
Bolted connection is connected to bolt intermediate two ends respectively, and attaching nut is threaded with bolted connection.
Bicycle seat height adjuster described in the utility model, grafting cylinder grafting is stretched into socket joint cylinder, with grafting
Stretch into that depth is corresponding, the support square hole matching in the upper corresponding one group of supported hole of socket joint cylinder sets square bolt, supporting circular holes
Matching sets cylindrical bolt, and screwed hole of the cylindrical bolt from square bolt is passed through, and square bolt and cylindrical bolt form ten
Word cross support, offsets for supporting grafting cylinder with grafting cylinder bottom；Simultaneously because being coated with and socket joint cylinder on the wall of grafting cylinder side
The elastic layer of inwall tight fit, so allowing for grafting cylinder will not easily deviate from socket joint cylinder, maintain the connective stability of the two,
This bicycle seat height adjuster has prevented the generation of position shift phenomenon between socket joint cylinder and grafting cylinder in ride,
The inconvenience that frequent regulation is carried out to height of seat is avoided, the Experience Degree of bicyclist is improve.
