The invention discloses a bicycle traction device capable of preventing a traction rope from winding. The device comprises a first fixed frame and a frame, wherein the left side of the frame is sleeved with a second fixed frame; a bolt is in threaded connection with the middle position of the second fixed frame; the right side of the frame is sleeved with a first fixed frame; a rope winding chamber is fixedly mounted on the right side of the first fixed frame; the front side and the rear side of the interior of the rope winding chamber are movably connected with rope winding drums through bearings; pull ropes are wound outside the rope winding drums; rockers are fixedly installed at the front ends of the rope winding drums; the front ends of the rockers extend out of the rope winding chamber; positioning frames are fixed to the front side and the rear side of the bottom end of the right side of the rope winding chamber; and the top ends of two sets of second springs are fixedly installed on the inner wall of a jacket. The bicycle traction device overcomes the problem that when a rear vehicle is dragged, a traction rope may fall off in a long-time traction process, and consequentlythe rear vehicle cannot be continuously dragged.

    本发明公开了一种防止牵引绳缠绕的自行车牵引装置,包括第一固定架和车架,所述车架左侧套设有第二固定架,且第二固定架中间位置处螺纹连接有螺栓,所述车架右侧套设有第一固定架,且第一固定架右侧固定安装有收绳室,所述收绳室内部前后两侧皆通过轴承活动连接有收绳筒,且收绳筒外部缠绕有拉绳,所述收绳筒前端固定安装有摇杆,且摇杆前端延伸至收绳室外部,所述收绳室右侧底端前后两侧就诶固定有定位架,两组所述第二弹簧顶端皆固定安装在夹套内壁。本发明避免了在对后车进行牵引时,牵引绳在长时间牵引过程中可能会发生脱落,导致无法对后车进行继续牵引的问题。
