The invention belongs to the technical field of rear wheel supports, and particularly relates to a rear wheel support which comprises a fixed plate, a pedal locking plate, adjusting frame rods, a support base, a first spring and a second spring. The adjusting threaded sleeve drives the distances between the two adjusting frame rods and the frame rod base to be lengthened and shortened through threaded fit. The two adjusting frame rods are of telescopic structures; when the rear wheel of the electric bicycle needs to be maintained, the rear wheel needs to be supported through the rear wheel support, at the moment, in order to guarantee the space during maintenance, when the rear wheel support is supported, the two adjusting frame rods cannot be shortened, and under the state, the rear wheelsupport can be adjusted. By means of the designed lock mechanism, the telescopic inner rod cannot be contracted into the telescopic outer sleeve due to upward pulling force in the state, and meanwhile, after the rear wheel is supported, the maintenance space cannot be affected after the rear wheel is supported.
本发明属于后轮支架技术领域,尤其涉及一种后轮支架,它包括固定板、脚蹬锁板、调节架杆、支架底座、第一弹簧、第二弹簧,所述两个调节架杆与架杆底座之间安装有调节螺纹套,通过旋转调节螺纹套,使得调节螺纹套通过螺纹配合驱动两个调节架杆与架杆底座之间距离的伸长和缩短;两个调节架杆均为伸缩结构;在电动自行车后轮需要维修的时候,需要将通过后轮支架后轮支起,此时为了保证维修时的空间,所以在支起后轮支架的时候,两个调节架杆就不能进行缩短,在这种状态下,本发明通过设计的锁机构使得伸缩内杆在这种状态下不会受到向上的拉力而缩入伸缩外套内,同时在将后轮支起后,在支起后不会影响维修空间。
