The invention relates to the technical field of urban rail safety devices, and discloses an urban rail transit passenger anti-pinch linkage device. The linkage device comprises two doors, box bodies,first rotating shafts, gears, racks, fixing columns and connecting plates, the box bodies are fixedly connected with the lower ends of the doors, and first through holes, second through holes and third through holes are formed in the box walls of the box bodies; the first rotating shafts are vertically hinged to the box walls of the box bodies, the first rotating shafts are sleeved with clockworksprings, one end of each clockwork spring is connected with a traction rope, the gears are coaxially connected with the first rotating shafts, the racks are meshed with the gears, and the fixing columns are fixedly connected into the box bodies. The traction rope in one box body penetrates through a first through hole or a second through hole to be fixedly connected with the fixing column in the other box body, the connecting plates are fixedly connected with the sides, close to the adjacent two box bodies, of the racks, and buffer mechanisms are connected with the side ends, away from the racks, of the connecting plates so that buffer can be formed between the two doors, and the clamping force of the two doors is buffered when people are clamped by the doors.

    本发明涉及城市轨道安全装置技术领域,公开了一种城市轨道交通乘客防夹联动装置,包括:两扇车门、箱体、第一转轴、齿轮、齿条、固定柱和连接板,箱体分别固连于车门的下端,箱体的箱壁上分别具有第一通孔、第二通孔和第三通孔,第一转轴竖直铰接于箱体的箱壁,第一转轴上套接有发条弹簧,发条弹簧的一端连接有牵引绳,齿轮同轴连接于第一转轴上,齿条与齿轮相啮合,固定柱分别固连于箱体内,一个箱体内的牵引绳穿过第一通孔或第二通孔与另一个箱体内的固定柱固连,连接板固连于齿条靠近两个箱体相邻的一侧,连接板远离齿条的一侧端连接有缓冲机构,能够在两扇车门之间形成缓冲,使车门在夹到人时两扇车门的夹紧力得到缓冲。
