Description

A kind of vibration damping support device

The utility model relates to a kind of vibration damping support device, particularly relates to a kind of vibration damping support device that is applicable to washing machine.

In the prior art, the family expenses washing machine generally adopts the mode of vibration reduction in components structure, adopts the suspension rod vibration damping structure mostly as automatic washing machine; The dehydration barrel of two-tub washing machine and for example, in its motor component, also has the spring damping structure, utilize the deadweight of machinery itself to produce enough frictional force simultaneously, reach the purpose that reduces vibrations and noise, therefore, the supporting foot place of existing washing machine generally no longer further adopts vibration damping structure, or sets up rubber pad in the supporting foot bottom simply.Its deficiency is: comparatively single for some functions, simple in structure washing machine, because weight own is lighter, adopt the vibration reduction in components structure still to be difficult to avoid the vibration of complete machine.

China's utility model patent discloses a kind of " snubber base of the vibration damping equipment of washing machine ", and the patent No. is 97118043.1, and it comprises a snubber base body, is fixed on an end of damping rod, be used for by and vibration damper lid between friction reduce vibration; A snubber base spring inserts the inwall of snubber base body, is used to keep the shape of snubber base body; With the pressure absorption plant, be formed in the snubber base body, therefore the pressure that produces when being used to absorb in the snubber base body inserts the vibration damper lid can prevent the plastic deformation of snubber base body, can prevent that washing machine from using the reduction of back vibration damping equipment damping capacity for a long time.Its deficiency is: structure is comparatively complicated, and cost is higher, is not suitable for function singleness, washing machine with low cost.

The purpose of this utility model provides a kind of vibration damping that is applicable to the washing machine vibration damping that weight is lighter and supports and put.

The purpose of this utility model can realize by following technical measures: it comprises the supporting foot main body, it is connected with the mechanical hull bottom of being supported, it is characterized in that the supporting foot main body is the T-bar structure, its stub end is positioned at the lower end as " sole ", the other end is a rod end, it passes the mechanical hull bottom, the surface is connected with a connection piece thereon, this link is subjected to the substantially horizontal of housing spacing, on the bar between stub end and the mechanical hull bottom surface, be with the pressure spring of an enough rigidity, bear the gravity of machinery and absorb vibration by this pressure spring.

The utility model can also be done following improvement: set up one that match with the spring external frame, its height spring housing less than the solid height of spring outside pressure spring, be used to guarantee that spring is vertically flexible.

The utility model can also improve further: the lower end of supporting foot main body " sole " sets up block rubber, and it can further absorb vibration, realizes the purpose of vibration damping better.

Improve further below the utility model can also be done: supporting foot main body T-bar is a bolt arrangement, its threaded end pass mechanical hull bottom and thereon the surface be connected with nut, this nut then is arranged in the hexagonal hole on the housing, be subjected to the substantially horizontal of housing spacing, can do moving of certain limit up and down in Vertical direction.Like this, will make the utility model not only have vibration-damping function, and, the function of regulating the supporting foot height also had.

The utility model has many advantages compared to existing technology: (1) adopts simple spring structure, and its spring has enough rigidity for institute's gravity supported, vibration damping effectively, and cost is lower.(2) as further employing block rubber, utilize its material behavior to absorb vibration on the one hand, the frictional force on increase and ground can reduce the displacement that is caused by vibration on the other hand.(3) adopt bolt arrangement as the supporting foot main body, can also do the height of regulating supporting foot, so that machine can adapt to the situation of ground injustice.(4) above advantage makes the utility model meet the requirement of the higher performance value ratio of the washing machine that weight is light, function is more single, also can be applied on other devices that need vibration damping.

Below in conjunction with embodiment the utility model is described in further detail:

Fig. 1 is one of the utility model embodiment's a main pseudosection;

Fig. 2 is the utility model embodiment's two a main pseudosection.

Vibration damping support device shown in Figure 1 is one of the utility model embodiment, it is by supporting foot main body 6, pressure spring 1, link 5 and block rubber 2 are formed, wherein, supporting foot main body 6 is the T-bar structure, its stub end 6 ' be tabular, the lower end that is positioned at supporting foot main body 6 is as " sole ", block rubber 2 cohere stub end 6 ' the bottom surface, the other end is a rod end, it passes mechanical hull 7 bottoms, the surface is connected with link 5 thereon, the spacing hole 7 of the substantially horizontal that this link 5 is arranged in housing 7 ' and, make link 5 relative to doing limited moving on the Vertical direction with housing 7; One pressure spring with enough rigidity be enclosed within stub end 6 ' and mechanical hull 7 bottom surfaces between bar on, a circular guide pillar is given prominence in mechanical hull 7 bottom surfaces, the guiding spring is vertical flexible to neutralizing.The utility model is born the gravity of machinery by pressure spring, because link is not fixed on the housing 7, but relative to doing moving on the Vertical direction with housing, mechanical hull and the utility model are to flexibly connect, therefore, when mechanical vibration, spring is flexible up and down with stressed variation, absorbs vibration, and block rubber 2 also can absorb vibration simultaneously, block rubber with coarse bottom surface can also increase the frictional force with ground, reduces the displacement that is caused by vibration.

Vibration damping support device shown in Figure 2 is the utility model embodiment's two, the T-bar of its supporting foot main body 6 is a bolt arrangement, be positioned at the hexagonal bolt head of the stub end 6 of its lower end ' be, be embedded in the block rubber 2, the other end of supporting foot main body 6 is a threaded end, it passes mechanical hull 7 bottoms, upper surface in housing 7 bottoms is connected with a hexagon nut 5, this nut then be arranged in hexagonal cylindrical hole 7 on the housing 7 ', can only do limited moving up and down, bolt head 6 ' and mechanical hull 7 bottom surfaces between bolt shank on be with the pressure spring 1 of an enough rigidity, and outside pressure spring, be with the helical spring cover of a height less than the solid height of spring 1, be used to guarantee that spring is vertically flexible, and the outstanding circular guide pillar in mechanical hull 7 bottom surfaces, it is vertical flexible to neutralizing also to guide spring, guarantees that spring is in the good working order; Destroy the upper surface of block rubber 2 for fear of spring, the higher reinforcement pad 3 of one hardness is set at the upper surface of block rubber.Present embodiment adopts bolt arrangement, vibration damping effectively not only, and, can also regulate the supporting foot height, make supporting foot have better fitness.
