Abstract
The invention discloses an assembly structure for a cover board and a housing of a motor. The assembly structure comprises a cover board and a housing, wherein trapezoidal positioning holes are formed from the wall surface to the upper edge of the housing; a positioning plate of which the section is rectangular is arranged at the circumference edge of the cover board; the upper bottoms A1 of the positioning holes are greater than the lower bottoms A2; and the width B of the positioning plate is equal to those of the lower bottoms A2. The assembly structure has the advantages of being simple in structure and convenient to assemble; the assembly difficulty is reduced; the assembled structure is firm; and pawls between the cover board and the housing can be evenly distributed, and do not become flexible or displace.
Description
Technical field
The present invention relates to a kind of cover plate of motor and the assembly structure of shell.
Background technology
What use in the MOD of refrigerator is all micromachine, and the structure of the attached cover plate 1 that Figure 1 shows that motor and shell 2, shell 2 supreme edge on wall offers the location hole 3 of rectangle, and cover plate 1 peripheral edge is along being provided with the spacer 4 with location hole 3 matching form.During assembling, engaged and make cover plate 1 and shell 2 relative positioning by location hole 3 with spacer 4, assembling should convenient operation, ensure that the ratchet 5 between assembling back shroud and shell is evenly distributed again, meet certain required precision, and cover plate and shell can not get loose, as shown in Figure 2.
For reaching above object, normally to be coordinated with the width dimensions of spacer by location hole and realizing.During interference fit, spacer can be put in location hole, but due to both sizes the same, cut mutually when assembling can produce plastics bits, install also hard; And during matched in clearance, although install easily, relatively loosening, ratchet skewness
Summary of the invention
Goal of the invention: for the problems referred to above, the object of this invention is to provide a kind of easy for installation, ensure assembling after ratchet can be evenly distributed the cover plate of motor and housing equipment.
Technical scheme: a kind of cover plate of motor and housing equipment, comprise cover plate, shell, described shell supreme edge on wall offers trapezoidal location hole, described cover plate peripheral edge is along being provided with the spacer that cross section is rectangle, the upper base A1 of described location hole is greater than the A2 that goes to the bottom, and the width B of described spacer is identical with A2.
The A2 end of going to the bottom of described location hole is recess, and the lower of described spacer matches along shape and described recess.Spacer width is gone to the bottom with location hole and is engaged, simultaneously recess snap-fit, and so not just linear contact lay, can prevent cover plate, shell relatively loosening.
Best, described recess is all arranged at the A2 two ends of going to the bottom of described location hole.
Described recess is arc, polygon.
Beneficial effect: compared with prior art, advantage of the present invention is that structure is simple, easy to assembly, and assembly difficulty reduces, sound construction after assembling, and the ratchet between cover plate and shell can ensure to be evenly distributed, and does not loosen and is not subjected to displacement.

Fig. 1 is cover plate and the shell mechanism schematic diagram of existing motor;
Fig. 2 is the structural representation after the cover plate of existing motor and shell assemble;
Fig. 3 is the partial structurtes schematic diagram of housing of the present invention;
Fig. 4 is the partial structurtes schematic diagram after the cover plate of motor of the present invention and shell assemble.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
The cover plate of motor and a housing equipment, as shown in accompanying drawing 3,4, comprise cover plate 1 and peripheral edge thereof along the spacer 4 be provided with, shell 2 and supreme edge is offered on wall location hole 3 thereof.
As shown in Figure 3, location hole 3 is trapezoidal, and its upper base A1 is greater than the A2 that goes to the bottom, and form " horn mouth " shape, the two ends of the A2 that goes to the bottom are recess 5, and recess is arc, triangle or other polygon etc.
As shown in Figure 4, the cross section of spacer 4 is rectangle, and its width B is identical with A2, and below spacer 4, two ends shape and recess 5 match.
The upper oral part of location hole is large, is convenient to spacer to load, and infraoral is little, and after cover plate compresses, both sides are located automatically, thus ensure that the requirement that ratchet is evenly distributed.Recess snap-fit, not just linear contact lay between such cover plate and shell, can prevent cover plate, shell relatively loosening.
