The invention discloses a spline type rod outer sleeve which comprises a rubber sleeve body (1)having a tubular structure. Spline grooves (11) are evenly formed in the inner wall of the body (1), sliding blocks (21) arearranged on the outer wall of the middle of a cross rod (2), and the sliding blocks (21) slide into the spline grooves (11), so that the body (1) is slidably connected with the cross rod (2). The spline grooves (11) are formed in the inner wall of the body (1), the sliding blocks (21) arearranged on the outer wall of the cross rod (2), the spline grooves (11) are evenly formed,so that the body (1) is evenly stressed; the cross rod (2) is sleeved with the body (1) along the sliding blocks, the body (1) can be slidably connected with the cross rod (2), so that people standingat different positions can conveniently move and hold the cross rod; and meanwhile, the contact surface of the body (1) and the cross rod (2) is increased, so that the body (1) and the cross rod (2)need certain force to move, and people can be effectively prevented from falling down during braking.

    本发明公开了一种花键式杆外套,包括橡胶套本体(1),本体(1)为管状结构,且本体(1)内壁均匀设置花键槽(11),横杆(2)中部外壁上设有滑块(21),且滑块(21)滑入花键槽(11)内,使得本体(1)与横杆(2)滑动连接。本装置通过在本体(1)内壁上设置花键槽(11),同时在横杆(2)外壁设置滑块(21),将花键槽(11)均匀设置使得本体(1)受力均匀,将本体(1)沿滑块套在横杆(2)外侧上,使得本体(1)可与横杆(2)滑动连接,方便站立在不同位置的人们移动握持;同时由于本体(1)与横杆(2)的接触面增加,使得本体(1)与横杆(2)的移动需要一定的力度,可有效防止刹车时人们摔倒。
