The invention relates to the technical field of rail traffic, and discloses an advertisement pull ring for a subway. The advertisement pull ring comprises a transverse rod, wherein fixed belts are uniformly mounted on the transverse rod; the bottom ends of the fixed belts are fixedly connected to a billboard; the middle part of the billboard is fixedly connected to advertisement paper; the bottomend of the billboard is fixedly connected to a buffer barrel; the middle part of the buffer barrel is movably connected to pistons; a buffer solution is stored between the two pistons; the inner sidesof the pistons are fixedly connected to a pull ring rope; and the other end of the pull ring rope is fixedly connected to a pull ring handle. The buffer barrel is arranged at the top end of the pullring, and magnets with same polarity are mounted inside the pistons such that a passenger holding a lifting ring overcome magnetic force to move inwards while leaning forwards by inertia to pull the pull ring in a brake or stop condition, and thus, effect of buffering force on a wrist is achieved and the wrist of the passenger is prevented from strain injuries resulting from emergency brake.
本发明涉及轨道交通技术领域,且公开了一种地铁用广告拉环,包括横杆,所述横杆上均匀安装有固定带,所述固定带的底端固定连接有广告牌,所述广告牌的中间固定连接有广告纸,所述广告牌的底端固定连接有缓冲筒,所述缓冲筒的中间活动连接有活塞,两个所述活塞的中间储存有缓冲液,所述活塞的内侧固定连接有拉环绳,所述拉环绳的另一端固定连接有拉环把手。本发明通过在拉环顶端设置缓冲筒,并在活塞内侧安装极性相同的磁铁,使得乘客在手握吊环时若遇到刹车或者停站的情况,身体受惯性前倾拉动拉环的同时,活塞克服磁力向内运动,从而起到缓冲手腕受力的作用,避免因紧急刹车乘客手腕受到突然的力而被拉伤。
