Abstract
The invention discloses a shock absorber and a washing machine with the same. The shock absorber comprises an outer cylinder with a buffer cavity, and a piston rod. The front end of the outer cylinder is provided with a damping chamber which is provided with a protective cover. The piston rod passes through the protective cover and the damping chamber to enter the buffer cavity. The part of the piston rod, corresponding to the damping chamber, is provided with a damping ring. A plurality of oil cavities are evenly reserved in the damping ring. By the technical means of evenly reserving the oil cavities in the damping ring, the piston rod generates a large amount of heat during operating; when the temperature of the surface of the piston, in contact with the damping ring, rises, lubricating oil is separated from the surface, of a damping strip, in contact with the piston; and spare lubricating oil in the oil cavities is released continuously to keep the piston rod moist in contacting with the damping ring, so that operational stability and continuity of the shock absorber are improved and the service life of the shock absorber is prolonged.
Description
Technical field
The present invention relates to damper, relate in particular to a kind of damper and the washing machine of this damper is housed.
Background technology
Existing tumbling-box washing machine comprises the shell that forms outward appearance, be arranged on the wash bucket that is used for depositing slurry in this shell, rotatably be arranged in this wash bucket and be used for clothing is washed cylinder with dehydrating operations, be arranged on the back of this wash bucket and be connected in the drive motors of cylinder.The huge centrifugal force that the balance weight of crossing the shell of phosphatization, electrophoresis, spraying triple protection and two heavinesses produces when being used for the balancing drum rotation is done repeating motion, adds that the acting in conjunction of washing powder and water makes clothes washing clean.What it was concrete is, by the rotatable front surface that is arranged on shell of door that clothing is put into or taken out, and the rotary shaft rack that is used for back-up roller is arranged on the back of wash bucket, spring is fixed on shell on the top of wash bucket, and is used for the bottom that damper that the decay cylinder is delivered to the wash bucket vibration is arranged on wash bucket.
When damper moves downward, need to strengthen damping, to eliminate amplitude, reduce pendulum spring because of the bigger pulling force of the excessive generation of displacement, the damping that moves downward increasing can be delivered to ground by the lower margin of washing machine shell, increase the frictional force on lower margin and ground simultaneously, this mode is of value to the machine even running.But the lubricating oil of damper is painted on the piston rod or amortisseur bar is carried out immersion oil and is nested with later on piston rod in the prior art, piston rod can produce a large amount of heats in the course of the work, when high when temperature is rapid, lubricating oil can be detached the contact-making surface of amortisseur bar and piston rod, cause insufficient lubrication, the friction of amortisseur bar and piston rod is sharply increased, even cause the amortisseur bar breakage, cause damper damping instability at work, and shorten the service life of damper, increase customer using cost.
Therefore, prior art needs further improvement and develops.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of damper and the washing machine of this damper is housed, increase stability and the continuity of damper, prolong the service life of damper.
For solving the problems of the technologies described above, the present invention program comprises:
A kind of damper for washing machine, it comprises that one has urceolus and a piston rod that cushions cavity, wherein, described outer cylinder front end is provided with a dampening chamber, described dampening chamber disposes a protecting cover, described piston rod passes described protecting cover, described dampening chamber inserts in the described buffering cavity, and described piston rod evenly is furnished with a plurality of oil storage space being provided with a damped ring with described dampening chamber corresponding position on the described damped ring.
Described damper, wherein, described oil storage space is oil storage hole or oil storage tank.
Described damper, wherein, an end of described piston rod is provided with connector, and described connector is provided with first lining, is equipped with first silencing cover on described first lining.
Described damper, wherein, an end of described urceolus is provided with second lining, is equipped with second silencing cover on described second lining.
A kind of washing machine wherein, is equipped with described damper on the described washing machine.
A kind of damper provided by the invention and washing machine of this damper is housed, employing evenly is furnished with the technological means of a plurality of oil storage space on damped ring, earlier with the damped ring immersion oil, also store lubricating oil in the oil storage space simultaneously, piston rod produces a large amount of heats in the course of work, when piston rod and the rising of damped ring contact-making surface temperature, lubricating oil can be detached the contact-making surface of amortisseur bar and piston rod, but the standby lubricating oil of oil storage space can discharge continuously, piston rod is contacted with damped ring keep lubricated, thereby reach permanent lubricated purpose, stability and the continuity of damper operator have been increased, prolong the service life of damper, reduced customer using cost.
Description of drawings
Fig. 1 is the fractionation structural representation of damper among the present invention;
Fig. 2 is the cross-sectional view of damper among the present invention.
The specific embodiment
The invention provides a kind of damper and the washing machine of this damper is housed, clearer, clear and definite for making purpose of the present invention, technical scheme and effect, below the present invention is described in more detail.Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the present invention.
The invention provides a kind of damper for washing machine, as Fig. 1 and shown in Figure 2, it comprises that one has urceolus 2 and a piston rod 3 that cushions cavity 1, and described urceolus 2 front ends are provided with a dampening chamber 4, described dampening chamber 4 disposes a protecting cover 5, described piston rod 3 passes described protecting cover 5, described dampening chamber 4 inserts in the described buffering cavity 1, and described piston rod 3 can move in described buffering cavity 1, thus the impulsive force in the buffering washing machine running; Described piston rod 3 is being provided with a damped ring 7 with described dampening chamber 4 corresponding positions, evenly be furnished with a plurality of oil storage space 8 on the described damped ring 7, at oil storage space 8 internal memory deposits oil, guaranteed that described piston rod 3 and described damped ring 7 contact-making surfaces keep continuous lubrication, have prolonged the service life of damper.
Further, described oil storage space 8 is oil storage hole or oil storage tank, has reduced its difficulty of processing, has saved manufacturing cost, and obvious oil storage hole or oil storage tank can adopt square opening, circular trough or other geometric formats.
In another preferred embodiment of the present invention, an end of described piston rod 3 is provided with connector 9, and described connector 9 is provided with first lining 10, is equipped with first silencing cover 11 on described first lining 10.And an end of described urceolus 2 is provided with second lining 12, is equipped with second silencing cover 13 on described second lining 12, thereby has reduced the noise of damper operator.
