Description

Cycle arm

Technical field

The utility model belongs to cycle arm, more particularly to a kind of cycle arm.

Background technique

Cycle arm is that one end is connected firmly with horizontal, the component that the other end and vertical tube of front fork are fastened with screw.Bicycle handlebar It is vertical to determine horizontal position, due to cannot be adjusted, when body is according to principle of human engineering, can not be adapted to bicycle, it will It slightly rides for a long time and wrist pain occurs, or sense tired out of riding aggravates, and cannot get good movement.Especially, mountain bike Or highway car, the bicycle of the professional motion rank for body-building, to will be relatively high vertical requirement.

Currently, occur in the market some stand it is adjustable, such as the Chinese utility model patent of Publication No. CN205273769 Prospectus discloses one kind and discloses a kind of adjustable-angle handle riser component, including upper holder block, lower lock block, head Guan An Dress portion adjusts bolt, lid, spring, support sleeve and adjuster locking lid on the right of adjuster, wherein upper holder block be equipped with match repeated hole, Mounting hole and intrados I, the lower lock block are equipped with internal thread hole a, intrados II, clamping end, connecting hole and spline groove, The head pipe mounting portion is equipped with through-hole, interconnecting piece and first pipe mounting hole, covers on the right of the adjuster equipped with spline protrusion I With limited block I, the mesoporous of the support sleeve is polygonal through hole, and the adjuster locking lid is equipped with limited block II, internal screw thread Hole b and spline protrusion II.Similarly with it, in the market there are also one kind and by locking cover locking hinge, hinge contact surface Between be equipped with the tooth of engagement and lock its angle.But the two all can in long-time use process, adjustable tooth or retaining mechanism There is gap, just will appear gap friction when leading to ride vertical receiving strength, issue noise will lead to over time Vertical adjustable joint two parts are loosened, finally may directly will lead to roll flute during professional motion again, and occur it is horizontal Strong strength of bearing is directly de- tooth displacement, it is this significantly shift it is abnormally dangerous during mountain bike rushes mountain.

Similarly, if non-adjustable and integrally formed handle stands or in this professional motion ride, because just Property impact cause wrist injured；Occur horizontal stiffness cracks to cause the person of riding that there is life danger.

For this purpose, guarantee in need is not in gap friction standing, together it is believed that we had both needed adjustable to stand When preferably can also ensure that in ride standing in high-tensile strength stroke, there is elastically-deformable space, be unlikely to occur Cross fracture or de- tooth substantially shift.

Utility model content

The above-mentioned technological deficiency of technology, the purpose of utility model of the utility model be to provide for it is a kind of have angle adjustable and Be not in gap friction, and there is elastic deformation space again in high-tensile strength stroke, to protect the handle of bicyclist's wrist Vertical, this is vertical also to have the substitute intensity prevented after fracture or de- tooth, to prevent from receiving in professional motion larger When strength is impacted, it is unlikely to occur danger of riding caused by horizontal big displacement.

In order to realize above-mentioned purpose of utility model, the utility model uses following technical scheme:

A kind of cycle arm, including with the first tube body of Chinese herbaceous peony axis connection and with horizontal the second tube body being fixedly connected, First tube body is equipped with the pipe spreader for being mounted on the bowl group upper end of bicycle head tube, and the second tube body outer end is equipped with fixed horizontal Locking clamp ring；It is hinged between first tube body and the second tube body；It is characterized by also including support steel bar and bolt, supporting steels Item is located at below the first tube body and the second tube body, and support steel bar is arc-shaped, and support steel bar front end is equipped with threaded portion, and rear end is equipped with Screw hole；It locks clamp ring lower part and is equipped with first lug, first lug is equipped with screw thread similar in axial and the second tube length direction Through-hole；First tube body lower part is equipped with the second lug, and the second lug is equipped with through-hole；The head of bolt is greater than through-hole, the spiral shell of bolt Bar portion outer diameter is less than through-hole, and the threaded shank of bolt passes through through hole whorl connecting screw hole, and the threaded portion of support steel bar front end connects Connect the tapped through hole.Preferably, the contact surface of the contact surface of the first tube body and the second tube body be all provided with it is with teeth, between tooth and tooth Intermeshing.

Preferably, contact gap and deformation gap between the contact surface of the first tube body and the contact surface of the second tube body it It is greater than tooth afterwards.

Compared with prior art, it using the cycle arm of above-mentioned technical proposal, has the following beneficial effects:

One, when receiving huge external force, being hinged structure can be released stress, and avoid structural failure.

Two, support steel bar can be avoided effectively when huge external force causes to be hinged failure, can be stood and be provided additionally for Support.

Three, steel bar adjustable-tightness is supported, carries out rigid adjusting according to actual needs.

Four, support steel bar has toughness, can effectively buffer.
