The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 to 7, the present invention provides a suspension rod assembly, which includes a suspension rod 10 and a shock-absorbing device disposed on the suspension rod 10, wherein the shock-absorbing device includes a damping bar 60 and a fixing seat 30, the fixing seat 30 includes a base 31 and a sleeve 32, the sleeve 32 is sleeved on the suspension rod 10, the sleeve 32 and the base 31 are relatively fixedly disposed in an axial direction of the suspension rod 10, the base 31 is connected with a bottom end of the suspension rod 10, and the damping bar 60 is sleeved on the sleeve 32 and relatively moves with the sleeve 32 in the axial direction of the suspension rod 10.

The hanger rod assembly bears the weight of the washing tub of the washing machine and absorbs the impact energy of the washing tub produced during washing and dewatering to ensure the stable operation of the washing machine.

In detail, as shown in fig. 1 to 3, when vibration is generated during the operation of the washing machine, the suspension rod 10 drives the base 31 and the sleeve 32 to move upward, so that the damping strip 60 sleeved on the sleeve 32 and the sleeve 32 move relatively in the axial direction, and a sliding damping force is generated between the damping strip 60 and the sleeve 32 to absorb impact energy generated by the vibration to the washing machine.

In the above scheme, the damping strip 60 is sleeved on the sleeve 32 instead of being directly sleeved on the suspension rod 10, so that the friction area of the damping strip 60 and the sleeve 32 in the axial relative sliding process is greatly increased compared with the friction area of the damping strip 60 in the direct sliding process on the suspension rod 10, and the sliding damping force generated by the suspension rod assembly is more stable. Furthermore, the damping strip 60 of the present invention does not directly rub against the suspension rod 10 to generate a damping force, but rubs against the outer wall of the casing 32 to generate a damping force, so that the casing 32 only needs to be made of a wear-resistant material, the present invention has low requirements on the material of the suspension rod 10, and only needs to ensure that the casing 32 has the characteristics of difficult deformation, high surface finish, etc., thereby reducing the cost of the suspension rod assembly.
