Description
Technical field
The present invention relates to the car part field, particularly the folding headstock assembly of a kind of high strength.
Background technology
Frame part is the basic structure body that consists of bicycle, also is skeleton and the main body of bicycle, and other parts also all are directly or indirectly to be installed on the vehicle frame.Front fork component is in position, the place ahead in bicycle structure, its upper end links to each other with the handlebar parts, and frame part cooperates with front pipe, and the lower end cooperates with front spindle unit, forms the guidance system of bicycle.Rotate handlebar and front fork, can make front-wheel change direction, played the directional tagging of bicycle.In addition, can also play the effect of control bicycle running, the stressing conditions of front fork component belongs to cantilever beam character, so front fork component must have enough character such as intensity.
Folding fixator in the prior art front fork component generally exposes outside, and directly fixes by jam nut, and its fixed form insufficient strength causes the headstock distortion easily.Have simultaneously the blank area complex structures such as bicycle now, intensity and rigidity are inadequate, and its folding effect is not good.
Summary of the invention
Technical matters to be solved by this invention provides the folding headstock assembly of a kind of high strength simple in structure, that connect reliable and folding convenient.
The present invention is achieved through the following technical solutions: a kind of high strength folds the headstock assembly, this headstock assembly comprises standpipe, front fork and vehicle frame head pipe, and the transverse tube welded with vehicle frame head pipe, described standpipe and vehicle frame head pipe joint also are provided with folders for standpipe, described folders for standpipe comprises top connection and lower adaptor, top connection and the standpipe lower end mouth of pipe are welded, lower adaptor lock onto the vehicle frame head pipe upper end mouth of pipe by fixation kit, described fixation kit comprises the major diameter screw, spring washer, metal washer and registration arm, be fixed with an inclination fixed block in front fork inside, inclination fixed block inside offers tapped bore, described major diameter screw passes spring washer from top to bottom, metal washer and lower adaptor are connected and fixed on the inclination fixed block, and described lower adaptor outer ring is to downward-extension and form an outer sleeve.
As preferred technical scheme, a circle screw thread circular groove is offered in described lower adaptor lower surface, is provided with screw thread in registration arm upper orifice outer ring, the lower surface thread connection of described registration arm and lower adaptor.
As preferred technical scheme, one side of described top connection and lower adaptor is chain connection, the opposite side of described top connection is welded with projection, the opposite side of lower adaptor is provided with hinges, connect a rotating eyelet bolt, other end at right angle setting one turning handle of described eyelet bolt on the hinges.
As preferred technical scheme, described nub side table is offered a U-shaped chute, and described turning handle and eyelet bolt junction are equipped with nut, and eyelet bolt cooperates with U-shaped chute by rotation and fixes by nut.
As preferred technical scheme, described top connection is the concave shape blanked part, and described lower adaptor is the flush type blanked part.
The beneficial effect of the folding headstock assembly of high strength of the present invention is: by the improvement to headstock component internal connection structure mode and part-structure shape, improve its whole linking intensity, greatly prolong the service life of headstock assembly, more simple, reliable at folding mode simultaneously, make folded size compacter, greatly improve safety and usability.
