Description

A kind of adjustable-angle handle riser assembly

Technical field

The utility model relates to bike and changes the outfit part field, particularly relates to a kind of adjustable-angle handle riser assembly.

Background technology

Cycle arm is commonly called as bike tap, directly controls the travel direction of bike, and the handiness of its manipulation is followed has direct relation vertical height and length. Vertical and vehicle frame collocation are got up, constitutes total upper length of tube. Bike is after overall dimensions of a car has been determined, and this length just secures, but each health size riding passerby is different, it may also be useful to mode is also different, and the changeable bicycle handlebar stem of same size cannot meet all demands riding passerby. How much suitable is this length? first can not be too short, ensure can perfectly stretch above the waist, it does not have the sensation cuddled up in a heap; Ensure that handlebar and your knee have certain safe distance, though stand trample time, knee also can not bump against handlebar. This is a bottom line at last. Secondly, always go up Guan Yuechang, upper body more stretches, and more easily has an effect, but the problem brought is exactly center of gravity reach, and handling declines. On the contrary, when upper pipe is shorter, you just can straight and upright upper body, obtain good manipulation and the visual field, certainly had an effect just not so freely. Except the length of horizontal aspect, in vertical, difference of altitude that is vertical and seat cushion there is impact equally. Seat cushion height is (can relate to below) easily determined relatively, with the use of front fork gasket ring, can even instead fill the difference of altitude adjusted with seat cushion vertical.

The handle riser used on existing market mainly comprises the neck pipe being connected with handle and the montant being connected with bike vertical tube of front fork, neck pipe is generally all connected by being connected structure with montant, after neck pipe and montant are connected by existing connection structure on the market, can not ensure that bike is when diameter run-out occurs, neck pipe and montant not relative movement, and when the relative angle of neck pipe and montant being adjusted, existing connection structure regulates very inconvenience.

Wherein upper holder block, lower lock block and first pipe installation portion adopt CNC complete processing to make;

Wherein first pipe installation portion adopts hollow out to design with lower lock block inside, while intensity is higher and lightweight, reduces costs;

Wherein spline protruding I and spline protruding II are running fit assembling with spline groove;

Wherein the Polygons through hole of limited block I and limited block II and support set is tolerance fit assembling, not only ensure that the firm of assembling but also serve spacing effect.

The beneficial effects of the utility model are:

1, this kind of adjustable-angle handle riser assembly adopts CNC to process, and without welding, first pipe installation portion and lower lock block inside all adopt hollow out to design, and while intensity is higher and lightweight, reduces costs;

2, lid spring assembling built-in with setter tightening cover on the right of setter, for convenience detach and adjustment angle, can reach, while adjustment angle, the effect increasing height;

3, change the outfit by being connected with the first pipe and handlebar of bike, easy for installation, can ensure to ensure the stability of handlebar in the process that bike jumps, highly versatile simultaneously.
