Abstract
The invention discloses a combined coil spring. The combined coil spring is composed of a stress shaft, multiple elastic units capable of continuously providing restoring force and a spring box arranged outside the elastic units, wherein the stress shaft is sequentially sleeved with the elastic units in the axial direction. The stress shaft is rotationally sleeved with the inner ends of the elastic units. Each elastic unit can be fixed to the outer wall of the stress shaft through a limiting piece. The outer ends of the elastic units can be fixed to the inner wall of the spring box through the limiting pieces. The center part of the top end of each elastic unit partially protrude outwards to form a protrusion. The center portion of the bottom end of each elastic unit is recessed inwards to form a sunken portion. The diameter of sunken portions is larger than that of the protrusions so that the protrusions of the elastic units located on the lower layer can be inserted into the corresponding sunken portions of the elastic units on the upper layer and the elastic units located on the lower layer and the elastic units located on the upper layer can relatively rotate with the same axis as a rotating axis. By the adoption of the combined coil spring, design and mounting are facilitated, disassembly and maintenance are fast, and the use efficiency of the coil spring is improved greatly.
