Abstract
The invention discloses a washing machine damping suspension rod, relates to the household electrical appliance fitting field, and comprises a pedestal, a circular pipe, an upper cover and a suspension rod; the circular pipe is welded on the pedestal; the bottom of the upper cover is provided with a short pipe; the short pipe is connected with a piston; the piston is connected with a spring; the other end of the spring is connected with the pedestal; one side of the circular pipe is provided with an air inlet pipe; the top of the upper cover is in a semispherical shape; the suspension rod penetrates the upper cover and the circular pipe, and is connected with the outer end of the piston. The air inlet pipe can inflate certain amount of air into the circular pipe so as to enlarge the air pressure in the circular pipe, thus enlarging piston resistance, and spring action of the spring is combined so as to improve damping effect.
Description
Technical field
The present invention relates to household electrical appliance accessory field, be specifically related to a kind of washing machine shock-absorbing suspension rod.
Background technology
The vibration balancing problem of Large Copacity automatic washing machine is one of difficult problem in washing machine development process always.The washing machine of low capacity is due to the lighter in weight of self, and the rigidity of required damping spring and the damping characteristic of absorbing vibrational energy are not very large, therefore can be balanced by existing structure.When capacity becomes very large time, because the weight of self is comparatively large, the vibrational energy produced when eccentric vibrating is also comparatively large, therefore needs the spring supporting of large rigidity, also need large damping to coordinate absorbing vibrational energy with it, this problem is not well solved at present simultaneously.Application number is that CN201320704957.5 discloses a kind of rotary drum washing machine combined type shock-absorbing suspension rod, and it is characterized in that forming airtight cavity by damping sleeve upper end cover, damping sleeve body and damping sleeve bottom end cover, the spring be sleeved on suspension rod is arranged in airtight cavity; Matched in clearance is formed between suspension rod and damping sleeve upper end cover, rubber base plate is pressed with between damping sleeve body and damping sleeve bottom end cover, suspension rod is set with friction plate, friction plate is fitted between damping sleeve upper end cover and damping sleeve body, the vibrating noise that this invention produces when effectively can reduce the full-automatic type eccentric motion of Large Copacity, but the elastic force of this kind of shock-absorbing suspension rod is fixed, can not regulate according to the actual service condition of washing machine, still there is more deficiency in damping property.
Summary of the invention
The object of the present invention is to provide a kind of washing machine shock-absorbing suspension rod, to solve the above-mentioned multinomial defect caused in prior art.
A kind of washing machine shock-absorbing suspension rod, comprise base, pipe, upper cover and suspension rod, described pipe is welded on base, be provided with short tube bottom described upper cover, short tube is connected with piston, and piston is connected with spring, the other end of spring is connected with base, the side of pipe is provided with air inlet pipe, and the top of upper cover is hemispherical, and described suspension rod is equipped with and is connected in upper cover with pipe and with the outer end of piston.
Preferably, described base is connected with hinge.
Preferably, described air inlet pipe is provided with pressure-reducing valve.
Preferably, described pipe has plastics or aluminum alloy materials to make.
The invention has the advantages that: this kind of shock-absorbing suspension rod, air inlet pipe can be utilized in pipe to be filled with a certain amount of gas, increase the air pressure in pipe, increase the resistance of piston, coordinate the elastic force effect of spring again, improve damping effect, described base is connected with hinge, base is facilitated to be connected with washing machine barrel, when needed, described air inlet pipe is provided with pressure-reducing valve, can need to reduce the air pressure in pipe according to the actual use of washing machine, damping effect is made to reach best, described pipe has plastics or aluminum alloy materials to make, material source is extensive, light weight, with low cost.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of washing machine shock-absorbing suspension rod of the present invention.
Wherein: 1-base, 2-pipe, 3-upper cover, 4-suspension rod, 5-short tube, 6-piston, 7-spring, 8-air inlet pipe, 9-hinge, 10-pressure-reducing valve.
Detailed description of the invention

As shown in Figure 1, a kind of washing machine shock-absorbing suspension rod, comprise base 1, pipe 2, upper cover 3 and suspension rod 4, described pipe 2 is welded on base 1, short tube 5 is provided with bottom described upper cover 3, short tube 5 is connected with piston 6, piston 6 is connected with spring 7, the other end of spring 7 is connected with base 1, the side of pipe 2 is provided with air inlet pipe 8, the top of upper cover 3 is hemispherical, described suspension rod 4 to be equipped with in upper cover 3 with pipe 2 and to be connected with the outer end of piston 6, this kind of shock-absorbing suspension rod, air inlet pipe 8 can be utilized in pipe 2 to be filled with a certain amount of gas, increase the air pressure in pipe 2, increase the resistance of piston 6, coordinate the elastic force effect of spring 7 again, improve damping effect.
In the present embodiment, described base 1 is connected with hinge 9, facilitates base 1 to be connected with washing machine barrel, when needed, described air inlet pipe 8 is provided with pressure-reducing valve 10, can need to reduce the air pressure in pipe 2 according to the actual use of washing machine, makes damping effect reach best.
In addition, described pipe 2 has plastics or aluminum alloy materials to make, and material source is extensive, and light weight is with low cost.
Based on above-mentioned, the present invention can utilize air inlet pipe 8 to be filled with a certain amount of gas in pipe 2, increases the air pressure in pipe 2, increases the resistance of piston 6, then coordinates the elastic force effect of spring 7, improves damping effect.
As known by the technical knowledge, the present invention can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Within the scope of the present invention all or be all included in the invention being equal to the change in scope of the present invention.
