Abstract
The utility model relates to a foldable bicycle with the vibration-proof function. The bicycle adopts the structural form that a rod is connected by an inclined shaft pin and is pulled by a rope, and the bicycle is folded vertically. A hasp lock of the rope is loosened, the end of a saddle rod is held by hand. The bicycle is lifted, and the fold of the main bicycle can be completed by means of the gravity of two wheels simultaneously. The two wheels can be automatically staggered a thickness of a wheel when coinciding because of the action of the inclined shaft pin. The two wheels are released when people ride the bicycle. Because of the pulling constrain of the rope and the action of an elastic body, the utility model can achieve the functions of unfold and vibration-proof.
Description
The utility model is a kind of being folded into just, and volume is small and exquisite, and is in light weight, the new type foldable bicycle brisk and that have shockproof function of riding.
Usually bicycle is formed the stressed vehicle frame of triangle by metal tube, and is the most firm.But heavy with the many deals of material, the inapplicable Folding Bicycle of this version.The Folding Bicycle vehicle frame generally is made up of single or double joint metal tube, and level is folding around axle, and this structure is solid for seeking to stable.Must strengthen the metal tube cross section, increase fastener, and corresponding supporting rod, thereby make structure complicated, limited further dwindling of volume and deal.
The purpose of this utility model is will provide a kind of to be provided with the bicycle that Xiao's connecting frame rod member and rope or metallic bond tractive are formed the anti-shock system vertical folding at the vehicle frame middle part.It not only has the stressed rational performance of triangle frame, also simplifies the structure, and has alleviated weight, has dwindled volume, and folding convenient is convenient to carry.
The purpose of this utility model is achieved in that changed by rope or metallic bond by the rod member of pulling force bears to triangle frame, to bear an end of the rod member of pressure and moment of torsion, promptly be connected into an integral body that can rotate around the axis with common axle Xiao in the vehicle frame middle part mutual intersection of rod member.So that can finish the function of vertical folding, the other end of corresponding rod member is fixed by rope or metallic bond tractive, with the restriction stressed member action radius of swaying: in being subjected to the rope of pulling force, seal in spring, or the spring of packing in the lower end of strut bar just has shockproof function.
The utility model has structurally only increased common axle Xiao because of in the speciality of having brought into play various materials aspect material, and bores a hole at corresponding rod member position.Just reach the folding and shockproof function of main body dexterously through assembling, need not twist or dismantle other bolt.Received simple in structure, volume is small and exquisite, the effect of in light weight, folding convenient.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Figure one is according to the folding bicycle structural representation with shockproof function that the utility model proposes.
Detailed below in conjunction with figure one according to concrete structure and the principle of work that the utility model proposes.
The formation of main car frame is by back rod member (1), and its front end is that a hole and axle Xiao (5) connect, and chain wheel is housed after a while, not end installing trailing wheel (adopt single leg to support, trailing wheel is installed in the rod member left side).Rod member (2), front end connects (front-wheel is on the left side of front fork) with single leg front fork, and the rear end is that a hole connects with axle Xiao (5).Strut bar (3), lower end can be installed spring and connect with the middle part of rope or metallic bond (8), and the upper end is a U type prong, is provided with hole on prong two limits, and the prong size is just in time inserted the porose end of rod member (1) and connected with axle Xiao (5) together.Rod member (4) upper end is provided with saddle, and the lower end is a hole, connects with axle Xiao (5).More than all rod members be garden shape metal tube, connecting ordinal position with axle Xiao (5) assembling is that rod member (4) is placed in the middle, rod member (1) occupies right, rod member (2) occupies a left side, rod member (3) is below rod member (1).More than four rod members systems run through and be assembled into the whole main car frame that is in the position in order by axle Xiao (5).Rope or metallic bond (8) middle part connect with rod member (3) lower end, two respectively with rod member (1), an end of rod member (2) joins, and forms two and is subjected to the triangle of forces.Body wt and impulsive force cause the telescopic spring of rod member (3) when riding, and cause rope or metallic bond (8) to fluctuate within the specific limits and reach the buffering antihunt action.Rod member (4) is formed two with rope or metallic bond (8) (6) and is subjected to the triangle of forces.
Have contact with (7) as long as main car unclamps when folding, handle is rotated 180 °, make front-wheel garden heart O go to O ' position, rod member (4) (direction of arrow) fell forward, hold the rod member end and mention bicycle, because the deadweight effect of front and back wheel, two take turns just automatically near also overlapping.
Claims (2)
1, a kind of shockproof folding bicycle, its vehicle frame is by back rod member (1), preceding rod member (2), strut bar (3), saddle bar (4), axle Xiao (5) and rope or metallic bond (8) tractive composition are subjected to the triangle of forces, it is characterized in that there is common axle Xiao (5) at the vehicle frame middle part, with back rod member (1), preceding rod member (2), strut bar (3), saddle bar (4) run through and are connected into integral body, and can rotate around axle Xiao (5).
2, shockproof folding bicycle according to claim 1 is characterized in that rod member (1) behind the vehicle frame, preceding rod member (2), and the not end of strut bar (3) is formed anti-shock system by rope or metallic bond (8) tractive.
