The invention provides a traction rod with a cushioning function, and relates to the technical field of traction rods. Comprising a traction rod and a traction rod cylinder which are connected with each other, a port communicated with the interior of the traction rod cylinder is formed in one end of the traction rod cylinder, and the traction rod extends into the traction rod cylinder from the port; the end, stretching into the traction rod cylinder, of the traction rod is connected with the inner wall of the traction rod cylinder through an elastic piece, buffer cavities are formed in the two sides, with the end of the traction rod as the boundary, in the traction rod cylinder, and when the end of the traction rod moves towards the buffer cavity in any side, the buffer cavities in the traction rod cylinder are communicated with the buffer cavities in the traction rod cylinder. The elastic piece on the side is compressed, and the elastic piece on the other side is stretched; the pre-compression of the spring has the advantages that the traction rod and the traction rod barrel can be in a relatively stable state, obvious relative displacement cannot occur when the stress is not large, and the spring can react more quickly to play a role in cushioning when the spring is subjected to large thrust or tension impact.
本发明提出了一种带缓震的牵引杆,涉及牵引杆技术领域。包括相互连接的牵引拉杆和牵引杆杆筒,所述牵引杆杆筒一端开设有与其内部相通的端口,所述牵引拉杆由端口伸入所述牵引杆杆筒内;所述牵引拉杆伸入所述牵引杆杆筒内的端部与所述牵引杆杆筒的内壁之间均通过弹性件相连,所述牵引杆杆筒内以所述牵引拉杆端部为界的两侧均形成缓冲空腔,且当所述牵引拉杆的端部向任一侧的缓冲空腔移动时,该侧的弹性件被压缩,另一侧的弹性件被拉伸;弹簧预受压的好处是牵引拉杆与牵引杆杆筒之间可以处于相对稳定状态,在受力不大时不会发生明显相对位移,而受到大的推力或拉力冲击时弹簧能更迅速反应起到缓震作用。
