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

A kind of locking structure of Foldable handlebar

Technical field

The utility model relates to bicycle handle bar, especially a kind of locking 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 when depositing is larger, the locking structure of existing Foldable handlebar is handlebar integral body to be torqued into the direction identical with vehicle body make bicycle integral body 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 locking 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 locking structure of Foldable handlebar, comprise pedestal, upper cover and handlebar, pedestal is cube-shaped structure, on pedestal, coaxial spaced is provided with upper cover, between pedestal and upper cover, be hinged with the handlebar of Level tune rotation, it is characterized in that: the rotating shaft of handlebar is passed down through pedestal, the rotating shaft bottom of pedestal below is hinged with a latch hook, and the outer rim of this latch hook is set for the eccentric; The upper and lower axial end radial equipartition of described gear is shaped with many spacing fins, and many spacing fin position-limited troughs made with pedestal upper surface of gear lower end coordinate, and many spacing fin position-limited troughs made with upper cover lower end of gear upper surface coordinate; Between the upper cover in handlebar outside and pedestal, retracing spring is installed.

And the equal symmetry of described upper cover dual-side is shaped with position-limited trough, the pedestal dual-side position that position-limited trough is corresponding is all shaped with the positioning plate coordinating with position-limited trough.

Advantage of the present utility model and good effect are:

The relatively folding structure of the utility model vertical handgrip 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.

The specific embodiment

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 locking structure for Foldable handlebar, comprises pedestal 7, upper cover 1 and handlebar 2, and if accompanying drawing 1 is to as shown in accompanying drawing 4, pedestal 7 is cube-shaped structure, and on pedestal, coaxial spaced is provided with upper cover 1, is hinged with the handlebar 2 of Level tune rotation between pedestal and upper cover,

Innovative point of the present utility model is:

For the fixing angle of handlebar, the rotating shaft 9 of handlebar is passed down through pedestal, and the rotating shaft bottom of pedestal below is hinged with a latch hook 8, and the outer rim of this latch hook is set for the eccentric, thereby latch hook rotation compresses or the distance loosened between pedestal and upper cover is controlled locking state; The upper and lower axial end radial equipartition of described gear is shaped with many spacing fins 3, and many spacing fin position-limited troughs made with pedestal upper surface of gear lower end coordinate, and many spacing fin position-limited troughs made with upper cover lower end of gear upper surface coordinate.

Automatically reset when guaranteeing that upper cover loosens, between the upper cover in described handlebar outside and pedestal, retracing spring 4 is installed.

In order to guarantee upper cover and base motion right alignment, the equal symmetry of described upper cover dual-side is shaped with position-limited trough 5, and the pedestal dual-side position that position-limited trough is corresponding is all shaped with the positioning plate 6 coordinating with position-limited trough.

Principle of work of the present utility model is:

Referring to state shown in accompanying drawing 1 and accompanying drawing 3, latch hook compresses pedestal, makes the gap smaller between pedestal and upper cover, thereby makes the mutual interlock of spacing fin of position-limited trough and the gear of pedestal, and the angle between gear and pedestal is locked, and handlebar can not rotate; State shown in accompanying drawing 2 and accompanying drawing 4, latch hook loosens pedestal, and retracing spring makes the gap between pedestal and upper cover become large, and the position-limited trough of this pedestal is separated with the spacing fin of gear, and gear can drive one-sided handlebar freely to 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: within not departing from the spirit and scope of the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
