The invention relates to the technical field of bus accessory equipment, and discloses a bus safety handrail which comprises a fixing box, a transverse rod is fixedly sleeved with the top end of the fixing box, a hole is formed in the bottom end of the fixing box, a limiting device is fixedly sleeved with the fixing box through the hole, and grooves are formed in the two sides of an inner ring of the limiting device. Limiting blocks are fixedly connected into the grooves, two movable columns are movably connected with the upper portion of the interior of the fixing box in a sleeving mode, a right supporting belt is placed on the outer side of one movable column, and a left supporting belt is placed on the outer side of the other movable column. The length of the right supporting belt is adjusted due to the pulling force of a passenger, meanwhile, the passenger holds a handle tightly, nitrogen is introduced into the right supporting belt to achieve interference sleeving of the right supporting belt and the limiting device, the purpose of fixing the length is achieved, the handrail can meet the requirements of passengers with different heights, the practicability of the handrail is improved, and the possibility of accidents caused by the fact that the passenger cannot reach the handrail is reduced.

    本发明涉及公交车附属设备技术领域,且公开了一种公交车用安全扶手,包括固定盒,所述固定盒的顶端内部固定套接有横杆,所述固定盒的底端开设有孔,且通过孔固定套接有限位装置,所述限位装置的内圈两侧开设有槽,且槽内固定连接有限位块,所述固定盒的内部上方活动套接有两个活动柱,所述一个活动柱的外侧放置有右支撑带,所述另一个活动柱的外侧放置有左支撑带。本发明通过右支撑带因乘客的拉力调节长度,同时通过乘客握紧手柄,将氮气通入右支撑带内实现右支撑带与限位装置的过盈套接,到达固定长度的目的,有利于扶手适应不同身高乘客的需求,提高了扶手的实用性,降低了乘客因够不到扶手而出现意外的可能。
