Abstract

The utility model relates to a universal vibration-reducing device for refrigerators, which solves the problem that the existing refrigerators generate multidimensional vibration, swinging movement and noise in operation. The utility model is characterized in that a vibration-reducing seat (3) is arranged in a bottom seat, a knuckle seat (4) is arranged on the vibration-reducing seat (3), an upper cover (1) is buckled on the bottom seat (2), and a regulating rod (6) which is connected with a refrigerator bottom seat (5) is arranged on the knuckle seat (4). The universal vibration-reducing device can effectively realize damping, the reduction of the vibration frequency of a refrigerator in operation, vibration reduction, and vibration isolation, enables the refrigerator to operate stably, prolongs the service life of the refrigerator, reduces noise, and protects environment. Therefore, the universal vibration-reducing device can be used for reducing vibration for refrigerators and refrigerating cabinets.

Description

Universal damping device for refrgerator

The utility model relates to a kind of vibration absorber, particularly a kind of universal vibration absorber of refrigerator that is used for the refrigerator bottom.

In the prior art,, cause refrigerator to be in operation and produce multi-dimensional vibration and hydraulic shock vibration because of the reason of refrigerator employing tubular cold condenser and compressor arrangement form; The moment that starts and shut down is because the rapid variation of frequency also can make the refrigerator complete machine produce tangible runout; In addition, various types of refrigerators have difference because of the difference of design, technology, manufacturing technology level, and the vibration that is produced, sound level also are not quite similar; Refrigerator is behind the operation some cycles, and because of the wearing and tearing of components and parts, loosening, it is big that mutual gap becomes, and vibration and noise also increase thereupon, and the noise that this vibration of the dead of night is produced is more obvious.Though have some refrigerator base to sell in the market, it also only limits to raise or reduce refrigerator, or convenient when refrigerator is changed places, easily a little, do not play the effect of vibration damping and then reduction noise.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provide a kind of operating vibration frequency of refrigerator that can effectively reduce, vibration damping, vibration isolation have good shock attenuation result, the universal vibration absorber of refrigerator that refrigerator is operated steadily and can prolong its service life.

Technical solution of the present utility model is: one group of universal vibration absorber of refrigerator of the present utility model is placed under the footing of refrigerator, can reach the purpose of this utility model.The concrete structure of this vibration absorber is: around the bottom centre epirelief, have in the base (2) of epirelief periphery, inserting a bottom, to have fovea superior around the fovea superior annulus vibration damping groove, its center, its top be the rubber damping seat (3) of a slick and sly concave surface ball-and-socket around the center on one recessed annulus, top is arranged, in the slick and sly concave surface ball-and-socket on vibration proof mounting (3), corresponding applying is inserted and is shown the hemispherical toggle seat (4) with epirelief periphery on one, and the middle part is that hollow loam cake (1) is buckled on the base (2).Like this, the adjusting rod (6) that is connected with refrigerator base (5) passes loam cake (1), places on the toggle seat (4).

The utility model has following advantage compared to existing technology:

1. adopt gimbal design between toggle seat and the vibration proof mounting, formed unique sphere and paid the joint structure, have the free degree of X, Y, three directions rotations of Z, can produce the effect that universal automatic leveling is subjected to force direction.The effect that also has friction damping between sphere is paid.2. owing to the physical characteristic of rubber damping seat, itself just has good shock attenuation result, and design has rational structure in addition, can realize damping effectively, reduces the operating vibration frequency of refrigerator, vibration damping, vibration isolation.

3. can reduce the self-excited vibration that refrigerator produces effectively when work, can make its even running, can prolong its service life, reduce noise, the protection environment.

4. simple in structure, to make easily, cost is low, high efficiency.

The drawing of accompanying drawing is described as follows

This figure is an overall structure longitudinal sectional view of the present utility model, and wherein 1 is that loam cake, 2 is that base, 3 is that vibration proof mounting, 4 is that toggle seat, 5 is that refrigerator base, 6 is adjusting rod.

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment: around the bottom centre fovea superior, have and insert a bottom in the base (2) of epirelief periphery to have fovea superior around a fovea superior annulus vibration damping groove, its center, its top be the rubber damping seat (3) of a slick and sly concave surface ball-and-socket around the center on one recessed annulus, top is arranged, in the slick and sly concave surface ball-and-socket on vibration proof mounting (3), the corresponding applying inserted the hemispherical toggle seat (4) that a upper surface has the epirelief periphery, and the middle part is that hollow loam cake (1) is buckled on the base (2).The adjusting rod (6) that is connected with refrigerator base (5) passes loam cake (1) and places on the toggle seat (4).The vibration damping that can be used for refrigerator, refrigerator-freezer.

Claims

1, the universal vibration absorber of a kind of refrigerator, has base 2, it is characterized in that, fovea superior around bottom centre, have and insert a bottom in the base 2 of epirelief periphery and have a fovea superior annulus vibration damping groove, fovea superior around its center, one recessed annulus is arranged at its top, around the center on top is the rubber damping seat 3 of a slick and sly concave surface ball-and-socket, in the slick and sly concave surface ball-and-socket on vibration proof mounting 3, the corresponding applying inserted the hemispherical toggle seat 4 that a upper surface has the epirelief periphery, the middle part is buckled on the base (2) for hollow loam cake 1, and the adjusting rod 6 that is connected with refrigerator base 5 passes loam cake 1 and places on the toggle seat 4.
