The invention relates to a rod piece waterproof structure for rail transit turnout switching, which is characterized by at least comprising a first rod piece (1), a second rod piece (2), an equipmentshell (3), a hole sleeve part (4), a waterproof column (5) and a sealing ring (6), the first rod piece (1) and the second rod piece (2) are arranged in parallel to form a rod piece with a two-piece structure, the hole sleeve part (4) is provided with a middle hole, and the rod piece of the two-piece structure penetrates through the middle hole, the hole sleeve part (4) is fixed on the equipment shell (3), the sealing ring (6) is sleeved on the peripheries of the two structural rod pieces and is fixed in the hole sleeve part (4), and the waterproof column (5) is arranged in the hole sleeve part(4) and is inserted into a gap between the first rod piece (1) and the second rod piece (2). According to the rod piece waterproof structure for rail transit turnout switching, the probability that water flows into equipment from the joint of the two structural rod pieces can be reduced.

    本发明涉及一种轨道交通道岔转换用的杆件防水结构,其特征是:至少包括:第一杆件(1)、第二杆件(2)、设备壳体(3)、孔套零件(4)、防水柱(5)、密封圈(6),第一杆件(1)和第二杆件(2)并列形成两片结构的杆件,孔套零件(4)有中间开孔,两片结构的杆件从中间开孔穿过,孔套零件(4)固定在设备壳体(3)上,密封圈(6)套在两片结构杆件外周上并固定在孔套零件(4)中,防水柱(5)安装在孔套零件(4)内,并插入第一杆件(1)和第二杆件(2)之间的间隙。这种轨道交通道岔转换用的杆件防水结构,可以降低水从两片结构杆件的结合缝流入设备内部的几率。
