Describe the hanger rod component 100 for rotary drum washing machine according to embodiments of the present invention below in conjunction with the accompanying drawings in detail.Wherein, on
Above-below direction when lower direction normally uses with hanger rod component 100 is as the criterion.
With reference to shown in Fig. 1-Fig. 4, the hanger rod component 100 for rotary drum washing machine according to embodiments of the present invention may include that
Suspension rod 1, gooseneck bracket 2, fixing seat 3 and elastic component 4.
Specifically, as shown in 1 and Fig. 2, the cross section of gooseneck bracket 2 can be annular, and gooseneck bracket 2 is set in movably
On suspension rod 1, the inner peripheral surface of gooseneck bracket 2 contacts with the outer peripheral face of suspension rod 1, and in other words, suspension rod 1 and gooseneck bracket 2 are for sliding
Friction, such that it is able to, subtract the force of sliding friction of generation between suspension rod 1 and gooseneck bracket 2 to a certain extent as damping force
Small vibration, and abnormal sound can be eliminated.
Further, at least one of the outer peripheral face of the inner peripheral surface of gooseneck bracket 2 and suspension rod 1 can be formed for gooseneck bracket 2 He
The rubbing surface of friction is increased during suspension rod 1 relative motion.It is to say, rubbing surface can be formed on the inner peripheral surface of gooseneck bracket 2,
Rubbing surface can also be formed on the outer peripheral face of suspension rod 1, it is also possible on the inner peripheral surface of gooseneck bracket 2 and the outer peripheral face of suspension rod 1
Upper form rubbing surface respectively.Thus, rubbing surface can increase the frictional force between gooseneck bracket 2 and suspension rod 1 to a certain extent,
Increase damping force, improve the damping capacity of hanger rod component 100.
As depicted in figs. 1 and 2, fixing seat 3 may be provided in the bottom of suspension rod 1, and one end of elastic component 4 can be with gooseneck bracket 2 phase
Even, the other end of elastic component 4 can be connected with fixing seat 3.During gooseneck bracket 2 motion, fixing seat 3 and gooseneck bracket 2
Between distance change, i.e. there is relative motion, suspension rod 1 and suspension rod relative to fixing seat 3 and suspension rod 2 in gooseneck bracket 2
Forming force of sliding friction between seat 2, this frictional force can form damping force.The arranging of rubbing surface can increase rubbing between the two
Wiping power, thus increase damping force；Meanwhile, in the process, elastic component 4 can deform upon, the elastic component after deforming upon
4 have restorable performance, and so, the restoring force of elastic component 4 can provide part damping force, subtracts to a certain extent
Slow speed of related movement between suspension rod 1 and gooseneck bracket 2, reduce gooseneck bracket 2 moving range.
Wherein, when elastic component 4 is in free state, between gooseneck bracket 2 and fixing seat 3 at least the one of suspension rod 1
The cross-sectional area of part can be incremented by the direction of fixing seat 3 from gooseneck bracket 2.Such as, shown in Fig. 1 and Fig. 2
In example, elastic component 4 is in free state, the horizontal stroke of the latter half between gooseneck bracket 2 and fixing seat 3 of suspension rod 1
Sectional area is being gradually increased on the direction of fixing seat 3 from gooseneck bracket 2.
When rotary drum washing machine load carries out washing or during the work such as dehydration, and cylindric washer rotates, and suspension rod 1 slides in gooseneck bracket 2
And driving gooseneck bracket 2 to move, during cylindric washer deviation rotary shaft, suspension rod 1 gradually slides in gooseneck bracket 2, fixing seat
Distance between 3 and gooseneck bracket 2 is gradually reduced, and connects with gooseneck bracket 2 when the part that the cross-sectional area of suspension rod 1 is incremental slides into
When touching, the outer peripheral face of suspension rod 1 contacts with the inner peripheral surface of gooseneck bracket 2 more closely and contact area causes more greatly force of sliding friction to increase
Greatly, and the distance between gooseneck bracket 2 and fixing seat 3 is the least, and the force of sliding friction between suspension rod 1 and gooseneck bracket 2 is the biggest,
Thus damping force that hanger rod component 100 is provided that is the biggest, i.e. cylindric washer is the biggest with the offset distance of rotary shaft, hanger rod component 100
Damping force is the biggest, and then so that hanger rod component 100 can be according to the loading condition damping adjusting power of cylindric washer.Thus,
Noise can be reduced, reduce vibration, improve the stability of rotary drum washing machine, and the simple in construction of suspension rod 1, handling ease.
The hanger rod component 100 for rotary drum washing machine according to embodiments of the present invention, by being positioned at suspension rod 1 in gooseneck bracket 2
And at least one of cross-sectional area between fixing seat 3 is set to be incremented by the direction of fixing seat 3 from gooseneck bracket 2, from
