For reaching above-mentioned purpose, the utility model provides a kind of waterproof and discharge structure of electronic scales housing, it comprises a housing with base and loam cake, this base combines with this loam cake, the periphery ring of this base is provided with first groove, and the root edge of this loam cake is equipped with second groove of corresponding joint with first groove; And at least one osculum that is arranged in first groove floor.

In preferred embodiment, the first groove both sides of this base are respectively equipped with a long barricade and a short barricade, and the second groove both sides of this loam cake are respectively equipped with a short barricade and a long barricade.

In preferred embodiment, the long barricade of this first groove is located on the periphery inboard of base, and the short barricade of this first groove is located on the periphery outside of base; The short barricade of this second groove is located on the root edge inboard of loam cake, and the long barricade of this second groove is located on the root edge outside of loam cake.

In preferred embodiment, the long barricade of this first groove is located on the periphery outside of base, and the short barricade of this first groove is located on the periphery inboard of base; The short barricade of this second groove is located on the root edge outside of loam cake, and the long barricade of this second groove is located on the root edge inboard of loam cake.

In preferred embodiment, the long barricade of this first groove is resisted against short barricade one side of second groove, and the short barricade of this first groove is resisted against long barricade one side of second groove.

The waterproof of electronic scales housing of the present utility model and the characteristics of discharge structure and advantage are: the waterproof of electronic scales housing of the present utility model and discharge structure effectively improve existing disappearance really, when cleaning electronic scales, can utilize first and second groove to prevent that clean liquid from entering electronic scales inside from the side purling, and the clean liquid in careless inflow first groove is discharged from osculum, so can avoid clean liquid to infiltrate or residue in the inside of electronic scales, and then reach when using and have preferable stability and accuracy, make the utility model more progressive eventually, practical and meet user's demand.

Embodiment

Please consult earlier shown in Fig. 1,2,3, be respectively three-dimensional appearance synoptic diagram of the present utility model, perspective exploded view of the present utility model and profile status synoptic diagram of the present utility model.As shown in the figure: the waterproof of a kind of electronic scales housing of the present utility model and discharge structure, it is made of with at least one osculum 2 housing 1.

Above-mentioned this housing 1 includes a base 11 and a loam cake 12 that combines with base 11, the periphery ring of this base 11 is provided with first groove 13, and the root edge of this loam cake 12 is equipped with second groove 14 with first groove, 13 corresponding joints, wherein first groove, 13 both sides of this base 11 are respectively equipped with a long barricade 131 and a short barricade 132, and second groove, 14 both sides of this loam cake 12 are respectively equipped with a short barricade 141 and a long barricade 142, and the long barricade 131 of this first groove 13 is located on the periphery inboard (or outside) of base 11, and this weak point barricade 132 is located on the periphery outside (or inboard) of base 11, the short barricade 141 of this second groove 14 is located on the root edge inboard (or outside) of loam cake 12 in addition, and this long barricade 142 is located on the root edge outside (or inboard) of loam cake 12, so the long barricade 131 of this first groove 13 is resisted against short barricade 141 1 sides of second groove 14, and the short barricade 132 of this first groove 13 is resisted against long barricade 142 1 sides of second groove 14.

Each osculum 2 is arranged in the bottom surface appropriate location of first groove 13.In this way, be combined into the waterproof and the discharge structure of a brand-new electronic scales housing by said structure.
