Abstract
The utility model relates to a component of suspend system of washing machine, which belongs to the mechanical technology field of washing machine. The component comprises a suspender, a new bottom tee, a buffering cover and an outer coat of the buffering cover. The bottom tee is positioned under the buffering cover, with the outer coat wraps the buffering cover. The suspender supports the bottom tee, buffering cover and the outer coat of the buffering cover as a whole. The utility model is simple in structure and the vibration noise is low. When operating the washing machine, the buffering cover (rubber cover) works to absorb shock and reduce noise. The structure of the device is simple and the effect is distinct.
Description
Technical field
The utility model relates to a kind of washing machine suspension system parts, specifically a kind of buffer structure of suspension arrangement.Belong to the washing machine field of mechanical technique.
Background technology
What at present general suspension adopted all is telescopic, and this structure spring abutment of being hit by a bullet all is to adopt rubber, and there is a metal washer inserts in portion within it.This rubber parts in use because and the long-term friction between the spring housing, not only can produce noise, also can cause the wearing and tearing of self, uses sealing effectiveness of a specified duration more poor more, air damping power can reduce gradually, causes vibration, the noise increase of washing machine.
Summary of the invention
The purpose of this utility model is to provide a kind of buffer structure of suspension arrangement that can vibration-absorbing denoising, this device uses cushion collar and damping grease to replace air damping, structurally avoided the phenomenon of the air damping power reduction that produces owing to wearing and tearing, durable in use, effect of vibration and noise reduction is remarkable.
The purpose of this utility model is to take following technical scheme to realize:
A kind of buffer structure of suspension arrangement comprises suspension rod and a kind of novel lower ball base, it is characterized in that it also comprises cushion collar and cushion collar outer cover; Described lower ball base place cushion collar above, the cushion collar outer cover is coated on the outside of cushion collar, whole lower ball base, cushion collar and cushion collar outer cover are tightly embraced on suspension rod.
The buffer structure of aforesaid a kind of suspension arrangement, it is characterized in that wherein said cushion collar around be distributed with the same projection of ear.
The buffer structure of aforesaid a kind of suspension arrangement, it is characterized in that wherein said cushion collar around distribute be raised with four.
The buffer structure of aforesaid a kind of suspension arrangement is characterized in that also scribbling between wherein said cushion collar and the suspension rod damping grease.
Operation principle of the present utility model is: lower ball base, cushion collar and cushion collar outer cover are enclosed within the outside of suspension rod.Coat damping grease at suspension rod and cushion collar joint.Damping grease not only can increase damping force, and can reduce friction, and reduces noise.Cushion collar adopts flexible nitrile rubber to make, when load acted on the lower ball base, cushion collar was subjected to the extruding of cushion collar outer cover and produces distortion, tightly embraces suspension rod, thereby the frictional force between suspension rod and the cushion collar is increased, promptly obtained to vary in size and the damping force that changes with load.
Compared with prior art, the utility model has the advantages that: simple in structure, vibrating noise is low.Washing machine in the course of the work, cushion collar in the buffer structure (rubber parts) can play the effect of vibration-absorbing denoising to greatest extent.This apparatus structure is simple, and effect is remarkable.

Fig. 4 is core parts of the present utility model---the cushion collar structural representation.
Fig. 5 is that 4 A is to cutaway view.
The specific embodiment
Shown in Fig. 1-5, the buffer structure of a kind of suspension arrangement of the utility model is made up of lower ball base (1), cushion collar (2), cushion collar outer cover (3) and suspension rod (4); Lower ball base (1), cushion collar (2), cushion collar outer cover (3) are enclosed within the outside of suspension rod (4).Respectively coat the damping grease of 0.3-0.6g at B, C two places.Damping grease not only can increase damping force, and can reduce friction, and reduces because of fricative noise.When lower ball base (1) was stressed, by X portion enlarged drawing as can be seen, the magnitude of interference of 0.22mm between lower ball base (1) and the cushion collar (2) can make lower ball base (1) and cushion collar (2) sealing, prevents that the damping grease at B place from overflowing.Cushion collar (2) adopts flexible nitrile rubber to make, and structure as shown in Figure 4.4 projectioies (5) that ear is the same evenly distribute around it, when load acts on the lower ball base (1), cushion collar (2) is subjected to the extruding of cushion collar outer cover (3) and produces distortion (as the Y portion enlarged drawing among Fig. 1), tightly embrace suspension rod (4), frictional force between suspension rod (4) and the cushion collar (2) is increased, promptly obtained to vary in size and the damping force that changes, thereby made whole suspension reduce vibration, reduced noise with load.
The foregoing description does not limit the utility model in any form, and all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within the protection domain of the present utility model.
Claims (4)
1, a kind of buffer structure of suspension arrangement comprises suspension rod and lower ball base, it is characterized in that it also comprises cushion collar and cushion collar outer cover; Described lower ball base place cushion collar above, the cushion collar outer cover is coated on the outside of cushion collar, whole lower ball base, cushion collar and cushion collar outer cover are tightly embraced on suspension rod.
2, the buffer structure of a kind of suspension arrangement according to claim 1, it is characterized in that wherein said cushion collar around be distributed with the same projection of ear.
3, the buffer structure of a kind of suspension arrangement according to claim 2, it is characterized in that wherein said cushion collar around distribute be raised with four.
4, the buffer structure of a kind of suspension arrangement according to claim 1 is characterized in that also scribbling between wherein said cushion collar and the suspension rod damping grease.
