The invention relates to the technical field of public transport means, and particularly discloses a height-adjustable lifting ring which comprises a lifting ring body and a connecting block connected with the inner wall of a compartment. The inner wall of the hanging ring body is connected with rotating rings through torsional springs; a nylon belt with one end connected with the connecting block is wound outside the rotating ring, and two ends of the rotating ring are connected with two limiting plates; a positioning block is arranged in the hanging ring body, and a pressing groove with a built-in button is formed in the positioning block; the button is connected with the pressing groove through a reset spring. The pressing groove vertically communicates with a through groove, and two limiting steel balls are arranged in the through groove. Two sides of the waist part of the button are provided with limiting grooves of which the spacing is gradually increased along the direction close to the limiting plate; the maximum inner diameter of each limiting groove is smaller than the diameter of each limiting steel ball; a plurality of limiting holes are formed in the limiting plate; when the reset spring naturally extends, the two limiting steel balls abut against the bottom of the button and are connected with the limiting holes in a clamped mode. When the reset spring contracts, the limiting steel ball is clamped with the limiting groove, and a gap is formed between the limiting steel ball and the limiting plate. The height of the lifting ring is adjusted.

    本发明涉及公共交通工具技术领域,具体公开了一种高度可调的吊环,包括吊环本体、与车厢内壁连接的连接块;吊环本体内壁通过扭簧连有转动环;转动环外绕设有一端与连接块连接的尼龙带,转动环两端连有两限位板;吊环本体内设有定位块,定位块开设有内置按钮的按动槽;按钮通过复位弹簧与按动槽连接;按动槽垂直连通有通槽,通槽内设有两个限位钢珠;按钮腰部两侧开设有间距沿靠近限位板方向渐增的限位槽,限位槽最大内径小于限位钢珠直径且其中设有磁铁;限位板设有若干限位孔;复位弹簧自然伸长时,两个限位钢珠与按钮底部抵接、与限位孔卡接;复位弹簧收缩时,限位钢珠与限位槽卡接、与限位板存在间隙。本发明实现了吊环高度的调节。
