CN103895450A - Castor for refrigerators - Google Patents

Abstract

The invention relates to refrigerator parts, in particular to a moving component for refrigerators, more in particular to a castor for refrigerators, and aims to provide the castor for refrigerators to solve the problem that the refrigerators are difficult to move. The castor is in an integrally formed tube structure; a metal plate fitting the inner wall is fixed to the inner wall of a castor body. A step of forming an internal metal structure is added on the basis of an existing castor manufacture process; after forming, the internal metal structure is fixed and the outside of the internal metal structure is further provided with a castor structure by blow molding, and the castor is formed. The problem that the castor for refrigerators easily fails after long-term use by a great distance is solved effectively.

Description

Refrigerator roller

Technical field

The present invention relates to a kind of refrigerator member, particularly relate to a kind of mobile member of refrigerator, more specifically relate to a kind of refrigerator roller.

 

Background technology

Refrigerator roller, refers specifically in the present invention specifically the roller that move for refrigerator refrigerator body bottom, or may also be referred to as the member into refrigerator castor.After its interior arrangement wheel shaft, drive roller to rotate by the friction force between wheel shaft and roller, therefore the mating reaction between roller madial wall and wheel shaft has important effect for the movement of refrigerator.

But, because the deadweight of refrigerator is larger, and after inside holds food, its weight can further increase, after the mobile icebox of long distance, friction force between wheel shaft and roller madial wall causes roller madial wall serious wear, the aperture of wheel shaft installation position constantly increases, thereby the mating reaction between roller madial wall and wheel shaft was lost efficacy, and refrigerator moves not freely, is even difficult to mobile.

Therefore, blow molding mode based on current refrigerator castor, effectively solve the long distance of roller, long-time mobile pair roller causes damage, causes the mobile problem losing efficacy, become in current refrigerator manufacture the particularly manufacture of refrigerator member produce in problem demanding prompt solution.

?

Summary of the invention

The present invention is directed to current refrigerator roller and easily lost efficacy, cause refrigerator to be difficult to mobile problem, a kind of refrigerator roller is provided, the cylindrical structure being one of the forming, the adherent metal sheet that is fixed with also on described roller inwall.

Based on existing roller manufacturing process, increase the forming step of an interior metal structure, after inner metal construction forms, be fixed and further form roller structure in its outside blowing, thereby forming roller structure disclosed by the invention.

In use wheel shaft by with the rubbing effect of roller madial wall, realize the rotation of roller, and then drive refrigerator to move, the rub resistance of roller significantly strengthens, and has prevented the roller Problem of Failure causing due to wearing and tearing.

Further, described metal sheet inner side is also fixed with elasticity laminar texture.Thereby can avoid roller to use for the first time time, there is the problem of abnormal sound.

This posterior limiting shape structure can be the plastic construction of stratiform, can be also the rubber structure of stratiform, or other can be considered to elastic laminar texture at present.

Further, the invention also discloses on the outer wall of described roller and be also formed with projection.Also disclose in the present invention especially as point-like projection.This projection plays effect anti-skidding, stop on roller outer wall, ensures that roller is difficult for losing efficacy on smooth floor.

Meanwhile, the invention also discloses symmetry on the barrel of described cylinder and offer through hole.On the basis of technical scheme disclosed by the invention, can ensure on the basis of bearing force and rolling effect material saving cost by arranging of through hole.

In sum, adopt after technical scheme disclosed in this invention, effectively solved the problem that refrigerator roller easily lost efficacy after long-time, long distance is used.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand following detailed description of the invention and only be not used in and limit the scope of the invention for the present invention is described.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in width figure, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric centre.

Embodiment 1

As shown in Figure 1, a kind ofroller 3 for refrigerator, the cylindrical structure being one of the forming, theadherent metal sheet 2 that is fixed with also on described roller inwall.

During fabrication, first form themetal sheet 2 of tubular according to the external diameter of wheel shaft, the inside oftubular metal sheet 2 has formed wheelshaft installation position 1, and by fixingtubular metal sheet 2, blowingforms roller 3 structures.

When use, wheel shaft (not shown) is arranged in wheelshaft installation position 1, and wheel shaft and casing are fixed, utilize the effect between wheel shaft androller 3 inwalls, refrigerator body is moved.

 

Embodiment 2

On the basis ofembodiment 1, in the present embodiment, also described metal sheet inner side is also fixed with elasticity laminar texture especially, be preferably in the present embodiment elasticity ofplastics layer 5, as shown in Figure 2, the formation installation position,inner side 1 of elasticity ofplastics layer 5, elasticity of plastics layer is between wheel shaft andmetal sheet 2, in rotation, wheel shaft does not directly contact with metal sheet, rotates more smooth and easy.

 

Embodiment 3

On the basis ofembodiment 1 or 2, also preferred especially on the outer wall of described roller, be also formed with projection, as shown in Figure 2, be preferably in the present embodiment point-like projection 6.

In use, these point-like projections 6 are conducive to roller stop on smooth floor, ensure the stability under roller non-working condition.

 

Embodiment 4

On the basis of above-describedembodiment 1 ~ 3, in the present embodiment also particularly preferably on the barrel of described cylinder symmetry offer throughhole 4, can be with reference to the structure in figure 1 or Fig. 2.

Thereby do not affect in guarantee on the basis of roller use validity, can save productive costs.

 

The disclosed technical scheme of the present invention program is not limited only to the disclosed technical scheme of above-described embodiment, also comprises the technical scheme being made up of above technical characterictic combination in any.

The above is the specific embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
