Description
Technical field
The utility model relates to technical field of bicycles, especially a kind of Folding Bicycle with safety device.
Background technology
The environmental protection vehicle of bicycle for extensively liked by people, but when not needing to ride, its occupation space is bigger, the higher resident family of some floors particularly, when for safety needing,, carry upstairs comparatively inconvenience because of its volume is big with the bicycle carry it upstairs, as its folding then can saving is greatly taken up room and easy to carry, Folding Bicycle has just arisen at the historic moment.What Folding Bicycle generally adopted at present is the mode of using bolt, in use, when bicycle is adjusted to the running condition structure, need manually tight a bolt with fixing body frame structure for automotive, in the time need not folding, need manually to looser a bolt once more, waste time and energy, the while does not tighten because of bolt owing to meeting or causes bolt looseness because jolting in the cycling process shaken, thereby influences the safety of riding.
Summary of the invention
In order to overcome the deficiency of existing Folding Bicycle, the utility model provides the Folding Bicycle of the band safety device that a kind of deployed condition can effectively lock.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of Folding Bicycle with safety device, comprise front fork, handlebar, wheel, sprocket wheel and by upper beam, underbeam, front pillar, the vehicle frame that rear pillar and back vent constitute, handlebar and front fork are fixedly connected, front pillar and front fork are fixedly connected, the upper beam two ends of vehicle frame connect firmly short tube, the front end short tube and the front pillar of putting the beams in place connect firmly, rear end short tube and rear pillar connect firmly, be respectively equipped with axle sleeve in the connection place at short tube and upper beam two ends, respectively it is connected in the two ends of upper beam by bearing pin, the lower end of front pillar is connected with the front end of underbeam by bearing pin, the rear end and the middle part of underbeam are respectively arranged with bearing pin, the rear end bearing pin connects with the lower end of back vent, the middle part bearing pin connects with the rear pillar lower end, and the upper end of back vent is connected by bearing pin with the rear end of upper beam, and back vent is made up of back vent epimere and back vent hypomere, the back vent epimere is connected with the back vent hypomere is collapsible, also is provided with safety device on the back vent.
This safety device by from the extended position-limited trough of back vent hypomere folded end, be arranged on the spring on the back vent epimere, the positioning supports bar that is arranged on the back vent epimere is formed, position-limited trough is spacing fixing after expansion to the back vent epimere, compression spring makes the back vent epimere leave position-limited trough and realizes folding, one end and the back vent epimere of positioning supports bar fixedly are rotatably connected, the other end is provided with button, the length of positioning supports bar equates that with width after the back vent epimere is in position-limited trough after buckling, spring can not compress.
The beneficial effects of the utility model are, the Folding Bicycle of band safety device of the present utility model, and simple and reasonable, folding and expanding is convenient and swift, and deployed condition can positive lock, and riding safety is reliable.
