The invention relates to the field of fire-fighting equipment, and discloses a telescopic arm and a fire fighting truck. The telescopic arm comprises a first arm section (1), a second arm section (2),a third arm section (3) and a tail end arm section (4) which are sequentially arranged from outside to inside. The telescopic arm comprises a first drag chain (5) located in the first arm section (1), a first sectional material (7) located in the second arm section (2), a second sectional material (8) located in the third arm section (3) and a second drag chain (6) connected to the interior of the tail end arm section (4). The first section bar (7) is slidably arranged in the second section bar (8), and the second drag chain (6) extends into the second section bar (8) and is connected to thefirst section bar (7). By means of the technical scheme, the structures of the drag chain parts are all located in the arm sections, the drag chain structure can be well protected, external impact isavoided in the using process, and the service life of the drag chain is prolonged.

    本发明涉及消防设备领域,公开了一种伸缩臂及消防车,其中,所述伸缩臂包括从外内向内依次设置的第一臂节(1)、第二臂节(2)、第三臂节(3)和末端臂节(4),所述伸缩臂包括位于所述第一臂节(1)中的第一拖链(5)、位于所述第二臂节(2)中的第一型材(7)、位于所述第三臂节(3)中的第二型材(8)、连接于所述末端臂节(4)内部的第二拖链(6),所述第一型材(7)可滑动地设置在所述第二型材(8)中,所述第二拖链(6)延伸到所述第二型材(8)中并连接于所述第一型材(7)。通过上述技术方案,拖链部分的结构均位于臂节的内部,可以很好地保护拖链结构,避免在使用过程中受到外部的冲击,延长拖链的使用寿命。
