The hanger rod seat 20 is connected with the top end of the hanger rod 10, the sliding block 40 and the lower support 30 are both sleeved on the hanger rod 10 and can slide along the hanger rod 10 to adjust the position, the sliding block 40 is positioned between the hanger rod seat 20 and the lower support 30, and the sliding range of the sliding block 40 is limited by the hanger rod seat 20 and the lower support 30. The damping elastic member 50 is sleeved on the suspension rod 10, and both ends of the damping elastic member 50 are respectively abutted against the sliding block 40 and the lower holder 30. The lock nut 60 is screwed to the suspension rod 10, the lower holder 30 is disposed between the lock nut 60 and the slider 40, and the lock nut 60 can abut against the lower holder 30 to restrict the position of the lower holder 30 on the suspension rod 10 by the engagement of the lock nut 60 with the elastic damping member 50.

When the damping device is used, the sliding block 40 is connected with a moving part in the washing machine, and can move on the suspension rod 10 through sliding to drive the damping elastic part 50 to deform, so that the damping elastic part 50 absorbs the vibration of the moving part, and the damping purpose is achieved.

The lock nut 60 is screw-coupled to the suspension rod 10, and the position of the lock nut 60, and thus the lower holder 30, can be adjusted by rotating the lock nut 60 to adjust the compressible space of the shock-absorbing elastic member 50.

Alternatively, the damping elastic member 50 may be a spring, which is simple in structure and low in cost.

In order to make the compressible space of the elastic shock-absorbing member 50 have a size capable of meeting the working requirements of different models of washing machines, the suspension rod 10 is set longer to increase the moving range of the lock nut 60 on the suspension rod 10, thereby meeting different shock-absorbing requirements. However, the hanger rod 10 is long, and when the shock absorption decoration is assembled, the locking nut 60 needs to be installed by rotating one end of the hanger rod 10 until the hanger rod is moved to a proper position on the hanger rod 10, and the operation is not changed; when the position of the locking nut 60 needs to be adjusted according to the damping requirement, the rotating distance of the locking nut 60 is also long, the adjustment is time-consuming, and the operation is inconvenient.

In order to solve the above problems, the suspension rod 10 comprises at least two splicing rods 11 which are detachably connected, when the position of the lock nut 60 needs to be disassembled or adjusted, the two connected splicing rods 11 can be separated, and the lock nut 60 can be assembled or disassembled from the end part of the proper splicing rod 11, so that the moving distance required by rotating the lock nut is reduced, and the operation is simplified.

Illustratively, when the lock nut 60 needs to be removed, the splicing rod 11 with the lock nut 60 mounted thereon and the splicing rod 11 connected thereto are separated, and then the lock nut 60 is removed from the end portion of the splicing rod 11 nearest thereto. When the locking nut 60 needs to be installed to the preset position, the splicing rod 11 where the preset position is located is separated from the splicing rods 11 at the two ends, and then the locking nut 60 is selected to the splicing rod 11 where the preset position is located, so that the maximum adjusting distance of the locking nut 60 on the splicing rod 11 is one half of the length of the splicing rod 11, and the adjusting time is greatly shortened.

In order to increase the moving range of the locking nut 60 on the suspension rod 10, the rod diameters of all the splicing rods 11 are the same, so that the locking nut 60 can be smoothly moved from one splicing rod 11 to another splicing rod 11. The hanger rod 10 is provided with an external thread matched with the lock nut 60, and the external thread covers at least two splicing rods 11 to prolong the moving range of the lock nut 60.

Then all be provided with the external screw thread on ejector pin and the sill bar, and the external screw thread on the ejector pin splices in the top of external screw thread on bottom and the sill bar to make lock nut 60 can switch smoothly on ejector pin and sill bar.

In order to facilitate the connection of the two splicing rods 11, as shown in fig. 3, two adjacent splicing rods 11 can be fixed in a threaded connection manner, so as to facilitate the disassembly and assembly. In order to enable the external threads on the two splicing rods 11 after being in threaded connection to be connected into a whole, the bottom end face of the ejector rod is provided with a threaded hole, the top end face of the bottom rod is convexly provided with a connecting column, and the connecting column can be in threaded fit with the threaded hole so as to enable the bottom end face of the ejector rod to be abutted against the top end face of the bottom rod, and therefore the external threads at the connection positions of the two splicing rods 11 can be smoothly butted.

It can be understood that, when the external thread on the splicing rod 11 is processed, the splicing rod 11 can be connected, and then the external thread is processed on the outer wall of the suspender 10, so as to ensure the continuity of the external thread and enable the external thread at the splicing position to be spliced smoothly after the splicing rod 11 is connected.

In some embodiments, the positions of the connecting column and the threaded hole can be interchanged, that is, the connecting column is arranged on the bottom end face of the top rod, and the threaded hole is arranged on the top end face of the bottom rod, so that the detachable connection of the two splicing rods 11 can be realized.
