The invention discloses a vacuum tire expander for an electric bicycle, and belongs to the technical field of repairing of vacuum tires of electric bicycles. The tire expander comprises two screw rods which are arranged in parallel, a movable plate which is rotationally connected with the screw rods, and a fixed plate which sleeves one end of each screw rod through a sleeve; the movable plate sleeves the screw rod through a cylindrical nut, the cylindrical nut is arranged on the side, away from the fixed plate, of the movable plate, and a magnet is fixed to the side, close to the movable plate, of the fixed plate; and the movable plate is adsorbed on the magnet. According to the vacuum tire expander for the electric bicycle, the power mechanism is used for driving the tire expander, so that the movable plate and the fixed plate work cooperatively, and a tire puncturing part is accurately positioned and repaired; the tire repairing problem after the vacuum tire of the electric bicycle is punctured can be effectively solved, the repairing efficiency can be improved, and the problems of air leakage and the like can be reduced; the electric bicycle vacuum tire repairing device has the advantages of simple structure, convenience in operation and good repairing effect, and can be widely applied to repairing work of electric bicycle vacuum tires.
本发明公开了一种电动自行车用真空胎扩胎器,属于电动自行车真空胎修补技术领域。扩胎器包括平行设置的两根螺杆、与螺杆转动连接的移动板和通过套管套接于螺杆一端的固定板;移动板通过圆柱螺母套接于螺杆上,圆柱螺母设置于移动板上远离固定板一侧,固定板靠近移动板一侧固定有磁铁;移动板吸附于磁铁上。本发明采用上述一种电动自行车用真空胎扩胎器,通过动力机构驱动扩胎器,使移动板和固定板协同工作,对扎胎部位进行精确的定位和修补;不仅可以有效地解决电动自行车真空胎扎胎后的补胎问题,而且可以提高修补效率,减少漏气等问题的出现;具有结构简单、操作方便、修补效果好的优点,可以广泛应用于电动自行车真空胎的修补工作中。
