Abstract
The utility model relates to a swing rotation structure of a folding handlebar. A base of the swing rotation structure adopts a cuboid structure; one end of a supporting rod is fixedly arranged on one side wall of the base in a cantilever manner; the supporting rod is connected with a front fork of a bicycle; a swing rotation structure for controlling folding of the handlebar is mounted at the upper end of the base; the swing rotation structure specifically comprises rotating shafts, gears and single arms; the two rotating shafts are mounted at the upper end of the base in a bilateral symmetry manner; the gears capable of performing swing rotation adjustment around the respective rotating shafts sleeve the two rotating shafts; teeth are arranged on one side, facing the center, of each of the two gears, and the teeth of the two gears are meshed; each cantilever type single arm is fixedly arranged/manufactured on one side, facing the outside, of each of the two gears and extends out of the base. The relative folding structure of the handlebar replaces the conventional torsion structure, so that the handlebar saves more storage space; the structure is convenient to adjust; furthermore, the components are firm and reliable, and are long in service life.
Description
Technical field
The utility model relates to bicycle handle bar, especially a kind of rotation structure of Foldable handlebar.
Background technology
Bicycle handle bar is the vitals of middle control travel direction of riding, handlebar is normally fixed on front fork upper end, handlebar and front fork intersect vertically, like this, the space that handlebar takies in the time depositing is larger, the rotation structure of existing Foldable handlebar is handlebar entirety to be torqued into the direction identical with vehicle body make bicycle entirety in same plane, but handlebar size is still larger.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of rotation structure of reasonable in design, simple in structure, easy to use, reliability and durability Foldable handlebar is provided.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of rotation structure of Foldable handlebar, pedestal is cube-shaped structure, pedestal one sidewall cantilevered is fixed with one end of strut bar, this strut bar is for being connected with bicycle front fork, it is characterized in that: the rotation structure for controlling handle bar folding is installed in pedestal upper end, this structure specifically comprises rotating shaft, gear and single armed, on a left side, pedestal upper end, the right side is symmetrically installed with two rotating shafts, in these two rotating shafts, be all set with a gear that carries out rotation adjusting around rotating shaft separately, this left side, right two gears are all shaped with the mutual interlock of teeth of teeth and two gears towards center one side, two gears side towards the outside is all fixedly mounted with/has been shaped with a cantilevered single armed, the cantilevered of this single armed is stretched out pedestal outside.
And the axial end radial equipartition of described gear is shaped with many spacing fins, these many spacing fin position-limited troughs made with pedestal upper surface coordinate.
Advantage of the present utility model and good effect are:
The structure that the utility model vertical handgrip folds relatively replaces torsion structure in the past, makes handlebar more save storage space, and this structure is easy to adjust, and parts are solid and reliable, long service life.
Brief description of the drawings
Fig. 1 is integral structure schematic diagram of the present utility model;
Fig. 2 is rotation block construction schematic diagram of the present utility model;
Fig. 3 is the birds-eye view of Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A rotation structure for Foldable handlebar, as shown in Figure 1, pedestal 1 is cube-shaped structure, and pedestal one sidewall cantilevered is fixed with one end of strut bar 5, and this strut bar is for being connected with bicycle front fork.
Innovative point of the present utility model is:
Rotation structure for controlling handle bar folding is installed in pedestal upper end, this structure specifically comprises rotating shaft 3, gear 2 and single armed 4, on a left side, pedestal upper end, the right side is symmetrically installed with two rotating shafts 3, in these two rotating shafts, be all set with a gear 2 that can carry out around rotating shaft separately rotation adjusting, this left side, right two gears are all shaped with the mutual interlock of teeth of teeth and two gears towards center one side, two gears side towards the outside is all fixedly mounted with/has been shaped with a cantilevered single armed 4, the cantilevered of this single armed is stretched out pedestal outside and cantilever end for coaxial handle (figure omits handle portion),
For the angle of fixing handlebar, the axial end radial equipartition of described gear is shaped with many spacing fins 5, and these many spacing fin position-limited troughs made with pedestal upper surface coordinate.Handlebar by-pass cock is in the time of open mode, and the position-limited trough of this pedestal separates with the spacing fin of gear, and gear can drive one-sided handlebar freely to rotate; Handlebar by-pass cock in the time of locking state, the mutual interlock of spacing fin of the position-limited trough of pedestal and gear, the angle between gear and pedestal is locked, handlebar can not rotate.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: not departing from the spirit and scope of the utility model and claims, various replacements, variation and amendment are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
Claims (2)
