Abstract
The invention discloses a combined spring shock-absorbing suspension rod, which comprises a rod body, a connecting base, a mounting base, a group of springs and a fixing base, wherein the connecting base is positioned at the top end of the rod body, and the rod body is arranged on a shell of a washing machine through the connecting base; the mounting base is positioned at the lower part of the rod body for mounting an outer drum of the washing machine; and the fixing base is positioned at the bottom end of the rod body, and the group of the springs are sleeved on the rod body and positioned between the mounting base and the fixing base and connected together in series through a connecting sleeve. The combined spring shock-absorbing suspension rod adopts combined springs to change elastic coefficient of the suspension rod, improves shock-absorbing performance of the suspension rod, reduces shocking and moving distances of the washing machine, and reduces noise.
Description
Technical field
The present invention relates to a kind of rotary drum washing machine parts, is that a kind of being used for hung the shock-absorbing suspension rod of combined spring that is made of a plurality of springs be arranged on the washing machine shell with swirl washing machine external barrel specifically.
Background technology
In general, washing machine is to utilize the effect of washings and washing agent and by washing, cleaning, dehydration, drying and other steps, removes the device of the dirt that is stained with in (hereinafter referred to as washings) such as the clothes that holds in the cylinder, pillows.
Washing machine of the prior art can be divided into pulsator washing machine and tumbling-box washing machine.Wherein the structure of pulsator washing machine is seen Fig. 1, and it includes: the housing 11 that forms the washing machine outward appearance; Be provided with in the inside of housing 11 and hang fixingly by supporting member, and be used to hold the outer bucket 12 of washings; The rotatable inside that is installed in outer bucket 12, and be provided with the washtub 13 of agitator 14 in its bottom; Be installed in the downside of outer bucket 12, and be used to produce the drive motors 15 of the driving force of agitator 14 and washtub 13.Be used for the driving force selectivity of drive motors 15 is offered the power transmission 16 of agitator 14 and washtub 13; Be installed in the bottom of outer bucket 12, and be used for the drainage arrangement 17 of bucket 12 washings that hold outside discharge the outside, outer bucket 12 hangs by four suspension rods 18 and is arranged on the housing 11.Wherein, suspension rod 18 structures of the prior art are seen Fig. 2, and it is made up of the body of rod 181, Connection Block 182, mount pad 183, single spring 184 and holder 185.Wherein, Connection Block 182 links together the body of rod 181 and housing 11; Mount pad 183 is used for installing outer bucket 12; Holder 185 is used for fixing the lower end of spring 184.Owing to be single spring structure, the suspension rod coefficient of elasticity changes little, has just lost cushioning effect after single spring 19 compresses fully, thereby when washing machine washing and dehydration, suspension rod 18 can not well play cushioning effect, causes washing machine vibrations big and displacement is big.
Summary of the invention
In order to overcome the problem that single spring exists in the existing suspension rod, the purpose of this invention is to provide a kind of shock-absorbing suspension rod of combined spring, this shock-absorbing suspension rod of combined spring can change the coefficient of elasticity of suspension rod, improves damping performance, reduce washing machine vibrations and displacement, and can reduce noise.
The objective of the invention is to be achieved through the following technical solutions:
A kind of shock-absorbing suspension rod of combined spring comprises the body of rod, Connection Block, mount pad, one group of spring and holder, and Connection Block is positioned at the top of the body of rod, and the body of rod is arranged on the washing machine shell by Connection Block; Mount pad is positioned at body of rod bottom and is used for installing outer barrel of washing machine; The fixed seating is characterized in that in the bottom of the body of rod: one group of spring housing is contained on the body of rod and between mount pad and holder; Be cascaded by adapter sleeve between one group of spring.
Among the present invention, described adapter sleeve is made of upper end connecting portion, lower end connecting portion and central divider, and the upper end connecting portion is used for connecting upper springs, and the lower end connecting portion is used for connecting lower springs, and central divider is separated upper springs and lower springs.
Generally, the damping requirement that has the spring of two different coefficient of elasticity to be cascaded and just can to satisfy suspension rod, among the present invention, described one group of spring is two, two springs are cascaded by an adapter sleeve.The coefficient of elasticity of spring that is positioned at adapter sleeve top in described two springs is greater than the coefficient of elasticity of the spring that is positioned at the adapter sleeve bottom.
Suspension rod among the present invention is made up of a plurality of springs, is connected by adapter sleeve between adjacent two springs.In the washing machine course of work, utilize a plurality of serial springs, in the change of washing and water smoking realization suspension rod coefficient of elasticity, after a spring compresses fully, another root spring continues compression, improves damping performance with this, reduces washing machine vibrations and displacement and reduces noise.

The specific embodiment
A kind of shock-absorbing suspension rod of combined spring of the present invention comprises the body of rod 1, Connection Block 2, mount pad 3, one group of spring 4 and holder 5, and Connection Block 2 is positioned at the top of the body of rod 1, and the body of rod 1 is arranged on the washing machine shell by Connection Block 2.Mount pad 3 is positioned at the body of rod 1 bottom and is used for installing outer barrel of washing machine.Holder 5 is positioned at the bottom of the body of rod 1.One group of spring 4 is sleeved on the body of rod 1 and between mount pad 3 and holder 5; 4 on one group of spring is cascaded by adapter sleeve 6.
Generally, the damping requirement that has the spring of two different coefficient of elasticity to be cascaded and just can to satisfy suspension rod, in the present embodiment, one group of spring is two, two springs are cascaded by an adapter sleeve 6.The coefficient of elasticity of spring that is positioned at adapter sleeve 6 tops in two springs is greater than the coefficient of elasticity of the spring that is positioned at adapter sleeve 6 bottoms.Adapter sleeve 6 is made of upper end connecting portion 61, lower end connecting portion 62 and central divider 63, and upper end connecting portion 61 is used for connecting upper springs, and lower end connecting portion 62 is used for connecting lower springs, and central divider 63 is separated upper springs and lower springs.
In the washing machine course of work, sharp two serial springs, change in washing and water smoking realization suspension rod coefficient of elasticity, after a spring of lower end compresses fully, another root spring of upper end continues compression, improve damping performance with this, reduce washing machine vibrations and displacement and reduce noise.
