The invention provides a bicycle fixing frame. The bicycle fixing frame comprises a connecting rod, a turnover device, a supporting rod device and a vertical rod device, the connecting rod is composed of an upper connecting rod body and a lower connecting rod body, the upper connecting rod body and the lower connecting rod body are connected through the turnover device, the turnover device comprises a turnover base, a handle, a pull rod, a handle base, a positioning pin, a spring and a locking device, and the locking device is an improved technology and is composed of a V-shaped piece, a threaded sleeve and an adjusting knob. One side of the V-shaped sheet is fixed with the positioning pin, the other side of the V-shaped sheet is provided with a clamping port clamped on the pull rod, the screw sleeve is obliquely arranged at the lower end of the upper connecting rod, the screw rod end of the adjusting knob is screwed on the screw sleeve, and the screw rod end can abut against the clamping port end of the V-shaped sheet by rotating the adjusting knob, so that the clamping port abuts against the pull rod. Therefore, when the upper connecting rod does not need to be overturned, the pull rod cannot be easily pulled through the V-shaped piece, even if an automobile passes through a bumpy road, the pull rod cannot pull the positioning pin to be separated from the positioning bayonet of the overturning seat due to vibration, and a bicycle is prevented from falling off.

    本发明提供一种自行车固定架。该自行车固定架包括:连杆、翻转装置、支杆装置和立杆装置,连杆由上连杆和下连杆构成,上连杆和下连杆通过翻转装置连接,翻转装置包括翻转座、拉手、拉杆、拉手座、定位销、弹簧和锁紧装置,锁紧装置为改进技术,由V形片、螺套和调节旋钮构成,V形片一侧与定位销固定,V形片另一侧设有卡接在拉杆上的卡接口,螺套倾斜的设置在上连杆下端,调节旋钮的螺杆端螺接在螺套上,并通过旋转调节旋钮使螺杆端能够抵着V形片的卡接口端,使卡接口抵紧拉杆。这样当上连杆不需要翻转的时候,通过V形片使拉杆无法轻易拉动,即使汽车过颠簸路拉杆也不会因振动而拉动定位销脱离翻转座的定位卡口,防止自行车的掉落。
