The invention discloses an adjustable bus handrail not prone to shaking, and relates to the technical field of traffic equipment. The middle part of the surface of the cross rod is fixedly connected with an adjusting box; first screw holes are formed in the middle of the surface of the adjusting box; the inner wall of the first screw hole is in threaded connection with a screw; the opposite inner walls of the adjusting box are each provided with two symmetrical rectangular grooves. Triangular plates are fixedly connected to the middles of the inner walls of the two rectangular grooves; the ends of the two hinged supports are slidably connected with adjusting plates. Telescopic rods are fixedly connected to the middles of the lower surfaces of the adjusting plates; the end of the telescopic rod is fixedly connected with the middle of the triangular plate. The peripheral side face of the telescopic rod is sleeved with a telescopic spring. Through cooperation of the cross rod, the adjusting box, the reinforcing block, the ball body and the hand pull ring, the problem that standing passengers are easily injured by the hand pull ring is avoided, and potential safety hazards are avoided; meanwhile, when the height needs to be adjusted, only the screw needs to be rotated, the height of different people can be adapted, operation is convenient, and practicability is high.
本发明公开了一种可调节不易晃动的公交车扶手,涉及交通设备技术领域。本发明包括横杆,横杆表面中部固定连接有调节箱;调节箱表面中部开设有第一螺孔;第一螺孔内壁螺纹连接有螺杆;调节箱相对内壁均开设有两个相互对称的矩形槽;两矩形槽内壁中部固定连接有三角板;两铰座端部滑动连接有调节板;调节板下表面中部固定连接有伸缩杆;伸缩杆端部与三角板斜面中部固定连接;伸缩杆周侧面套设有伸缩弹簧。本发明通过横杆、调节箱、加强块、球体和手拉环相配合,避免了手拉环很容易碰伤站立乘客的问题,避免了安全隐患;同时在需要调节高度时,只需转动螺杆即可,能够适应不同人的高度,操作方便,实用性强。
