The bicycle head vertical stem can adjust spacing between the front fork vertical stem of which two ends are connected and fixed and the transverse handlebar, thereby adjusting the spacing between the transverse handlebar and a bicycle saddle, and humanized design can be realized.
Description
Technical field
The utility model relates to bicycle pipe part and connects fixed sturcture, and particularly a kind of scalable is the car head montant of spacing between front fork vertical bar and the cross handle fixedly.
Background technology
Being connected fixing (the first cross handle of car two ends form handle) through the first montant of car between the first cross handle of front fork vertical bar and car on the bicycle, specifically be that this car head montant one end wears and is fixed in this front fork vertical bar, and the other end also wears and be fixed in this car head cross handle.Spacing is come design-calculated according to man or Ms between first cross handle of car and the saddle at present, thereby embodies with male money or women money bicycle, yet people's the arm length difference opposite sex has determined can not adapt to all men or Ms with a bicycle.
Summary of the invention
In order to remedy above deficiency, the utility model provides a kind of car first montant, can regulate two ends and connect spacing between fixing front fork vertical bar and the first cross handle of car, thereby regulate spacing between first cross handle of car and the saddle, realizes human oriented design.
The technical scheme of the utility model is such realization: the first montant of a kind of car; Be installed between cross handle and the front fork vertical bar; By the first sleeve pipe of the car of fixing front fork vertical bar and fixedly the first standpipe of car of cross handle forms, the first sleeve pipe of this car becomes the L type to be connected with car head standpipe, and integrally formed; The first standpipe of this car end forms the flute profile mouth of pipe of being convenient to pass cross handle; This grooved mouth of pipe is provided with first open slot of being convenient to clamp through clamping mechanism cross handle vertically at least, and this channel pipe oral-lateral portion is provided with a detouchable regulating block, and this regulating block section is meniscus level; And when this regulating block inserted the inner side of this flute profile mouth of pipe, this meniscus level and this channel pipe interruption-forming were convenient to tighten up the circular port of cross handle.
As the further improvement of the utility model, this flute profile mouth of pipe axially extends along the first standpipe of this car, is convenient to regulate the spacing between this front fork vertical bar and the cross handle.
As the further improvement of the utility model, the first sleeve pipe mouth of pipe of this car is provided with second open slot of being convenient to through clamping mechanism clamp fitting front fork vertical bar vertically at least.
As the further improvement of the utility model, this regulating block side is formed with the concave arc surface that can be adjacent to this cross handle face by being adjacent to the inboard convex face of this grooved mouth of pipe.
As the further improvement of the utility model, this regulating block has hollow structure, and has the reinforced rib that can support this convex face and concave arc surface middle part.
As the further improvement of the utility model, this clamping mechanism by at least one group of lug being located at the open slot both sides, pass the set screw of this group lug and be rotated with and form in the setting nut of this set screw.
The useful technique effect of the utility model is: because the first standpipe of this car end forms the flute profile mouth of pipe of being convenient to pass cross handle; This grooved mouth of pipe is provided with first open slot of being convenient to clamp through clamping mechanism cross handle vertically at least, and this channel pipe oral-lateral portion is provided with a detouchable regulating block, and this regulating block section is meniscus level; And when this regulating block inserts the inner side of this flute profile mouth of pipe; This meniscus level and this channel pipe interruption-forming are convenient to tighten up the circular port of pipe fitting, when regulating block inserts the two sides of this flute profile mouth of pipe respectively like this, again behind the clamp fitting pipe fitting; Connecting fixedly, front fork vertical bar has different with the first montant actual pitch of the car between the cross handle; Realize thus regulating cross handle and front fork vertical bar spacing, thereby also regulate spacing between cross handle and the saddle, realize human oriented design.
