Description
The utility model relates to a kind of attachments of a bicycle, is a kind of bicycle saddle cushion fast lifting device.
The ordinary bicycle seat cushion is fixed on the seat cushion lifting bar, and lifting bar inserts in the hypsokinesis inclined tube of bicycle rack; Bench height varies with each individual, but just can not adjust when riding once fixing; Also need instruments such as spanner during adjustment, adjust very effort.Therefore, in the city, often running into red light, the stream of people discloses to squeeze and needs the people that usually suspend the bicycle that travels to feel that upper and lower bicycle is pretty troublesome, generally all bicycle saddle cushion is fallen very low, so that when running into red light or other things and need suspend bicycle, the only using foot point lands and holds bicycle and whole health does not need from getting off voluntarily.Red light one is removed, and tiptoe one is pedaled, and just can return to motoring condition at once.Though the lower bicycle that is of value to of seat cushion suspends and safety, has increased the energy dissipation in riding.Because in the time of by bike, it is the most laborsaving also foot-operated apart from seat cushion farthest the time that the height of seat cushion should make the people pedal when foot-operated, and people's shank stretches naturally to good.Therefore, reducing bench height makes riding safety, stops convenient but make that riding becomes has required great effort.In addition, using bicycle is recurrent thing, because the height difference, rides the bicycle used concerning the borrower or ride dangerously, inconvenient because of seat cushion is too high, or leg is not stretched directly effort, tiring when riding.These factors have brought certain restriction all for using widely of ordinary bicycle.
The purpose of this utility model just provides and a kind ofly can overcome above-mentioned defective, can regulate apace the bicycle saddle cushion height, make the laborsaving and safe bicycle saddle cushion fast lifting device of cycling.
The purpose of this utility model is achieved in that at the part upper edge circumference of bicycle saddle cushion lifting bar insertion bicycle rack evenly opens several rectangular mouthfuls of being parallel to the lifting bar axis, and each rectangular mouthful of one side and several lock-joints connect; Or only present pad lifting bar inserts the pin of the part of bicycle rack along the evenly fixing several loads of circumference.Have the pin of the cylindricality supporting rod top, garden of base at another along evenly fixing several loads of garden week; Or along opening several rectangular mouthfuls of being parallel to garden cylindricality supporting rod axis garden week equably, each rectangular mouthful connects with several lock-joints on one side.One spring housing is arranged on the cylindricality supporting rod of garden or put into garden pipe, and can freely stretch as garden cylindricality supporting rod.This supporting rod and the described seat cushion lifting bar that has spring carried out socket, make each pin dock with the lock-joint socket joint, spring is executed the power that lifting bar and strut bar are broken away from because of being subjected to the lifting bar bottom and the extruding of strut bar base all the time to lifting bar, open a small gap in the upper end (or lower end) of lock-joint and make that pin is clamped on small gap when applying an external force opposite with spring force in lifting bar.This composite set is inserted in the vehicle frame hypsokinesis inclined tube, keep lifting bar outer wall and vehicle frame rear-inclined inside pipe wall that certain interval is arranged, the strut bar base is fixed by bolts to vehicle frame hypsokinesis inclined tube bottom.After setting up seat cushion, the installation of fast lifting power apparatus is promptly accused and is finished.When riding, reduce seat cushion, only need gently lift buttocks, just spring force makes pin separate with the lock-joint small gap as need; Promote seat cushion with femoribus internus again and drive the lifting bar rotation, certain angle makes pin and disengaging enter rectangular mouthful; Oppress cushion with buttocks again, pin just slides in rectangular mouthful, and lifting bar will descend; When seat cushion drops to extreme lower position, just push away with the seat cushion of femoribus internus with deflection, pin enters in the minimum lock-joint, and because buttocks is pressed on the seat cushion, and pin is just tightened by the lock-joint small gap, seat cushion just can not rotate.When needs rising seat cushion, lift buttocks, pin breaks away from small gap; Promoting seat cushion with femoribus internus drives lifting bar and rotates to an angle and pin and lock-joint are broken away from enter rectangular mouth; Lifting bar is moved up by spring force, and pin slides in rectangular mouthful; When seat cushion is raised to the extreme higher position, just push away with the seat cushion of femoribus internus with deflection, pin just enters in the lock-joint, and after buttocks was sitting on the seat cushion, pin was tightened by small gap, and seat cushion just can not rotate.
The utlity model has following advantageous effect: can directly be contained in the hypsokinesis inclined tube of ordinary bicycle vehicle frame and need not change the bicycle outward appearance, can adjust the bicycle saddle cushion height easily, apace, flexible, laborsaving when making driving, and safety, reliable, simple in structure, easy to process.
