Abstract
The utility model discloses a dustproof casing, which relates to a casing of an electronic product. The inner side of the end surface of the side wall of a box type upper cover of the dustproof casing is provided with a step; the outer periphery of the side wall of a box type lower cover is wrapped with a soft rubber sleeve, and the end surface of the soft rubber sleeve, facing the upper cover, extends inwards an end with an L-shaped cross section; the upper cover and the lower cover are mutually buckled and fixed to be a closed entirety by using a connecting piece, the end of the soft rubber sleeve on the side wall of the lower cover leans against the end surface of the side wall of the upper cover, and the outer convex part of the end of the soft rubber sleeve extends into the step of the side wall of the upper cover; and the inner side edge of the end surface of the side wall of the upper cover extends outwards an acute angled convex edge, and the convex edge is clamped into the end of the soft rubber sleeve on the side wall of the lower cover. The dustproof casing has good waterproof property.
Description
Technical field
The utility model relates to a kind of electronic product shell.
Background technology
Usually electronic product shell all adopts the loam cake of boxlike and the lower cover of boxlike to fasten mutually, and by connectors such as buckle or screws they is fixed as a sealed whole body.This shell structure form can enter its inner passage for dust stays at the piece of loam cake and lower cover joint.For this reason, people adopt sealing ring to stop up piece to reach the dustproof purpose at loam cake and lower cover joint.For example, dustproof casing shown in Figure 1 is left step 13 in end face 12 inboards of the sidewall 11 of the loam cake 1 of boxlike, at the sidewall 21 periphery bag flexible glues cover 3 of the lower cover 2 of boxlike, and extend internally out the termination 32 in " L " cross section, these flexible glue cover 3 end face 31 places towards loam cake 1.When loam cake 1 fastens mutually with lower cover 2, please referring to Fig. 2: the recline end face 12 of loam cake 1 sidewall 11 and the male part 33 that this flexible glue overlaps 3 terminations 32 of the termination 32 of flexible glue cover 3 stretches in the step 13 of loam cake 1 sidewall 11 on lower cover 2 sidewalls 21, and the termination 32 of flexible glue cover 3 constitutes the dust-proof seal ring that stops up pieces on lower cover 2 sidewalls 21.But this sealing and dustproof structure can not stop water and steam to enter loam cake 1 to fasten in the housing that forms mutually with lower cover 2, thereby can not guarantee that electronic component in the housing is not subjected to the influence of water or water vapour and damages.
The utility model content
The utility model aims to provide a kind of dustproof casing with good water resistance.
The technical solution of the utility model is: a kind of dustproof casing, and step is left in the sidewall end face inboard of boxlike loam cake; Extend internally out towards the end of the loam cake termination in " L " cross section of the sidewall periphery bag flexible glue cover of boxlike lower cover, this flexible glue cover; Loam cake and lower cover fasten mutually and by connector they are fixed as a sealed whole body, and the recline end face of loam cake sidewall and the male part of this flexible glue cover termination of the termination of flexible glue cover stretches in the step of loam cake sidewall on the lower cover sidewall; The end face inward flange of loam cake sidewall extends outward the fin that is acute angle, and this fin snaps in the termination of flexible glue cover on the lower cover sidewall.
The male part of described flexible glue cover termination and the sidewall of loam cake sidewall end face step overlap mutually, and this male part is producing compression with this step sidewall contact position.
Dustproof casing of the present utility model, the fin that utilizes the end face inward flange of loam cake sidewall to be acute angle snap in the termination of flexible glue cover on the lower cover sidewall, form the tight waterproof of annular and the enclosed construction of steam-preventing in flexible glue cover termination, so have favorable waterproof property.The additional waterproof construction of casing that should prevent dust is simple, easy to implement; Even loam cake and lower cover joint generation slight deformation can not influence its water resistance yet.And then the male part of flexible glue cover termination and the sidewall of loam cake sidewall end face step are overlapped mutually, this male part is producing compression with this step sidewall contact position after the assembling.Further improved water resistance.
Description of drawings
Fig. 1 is a kind of cross-sectional view of dustproof casing.
Fig. 2 is the local enlarged diagram of A portion among Fig. 1.
Fig. 3 is the cross-sectional view of the dustproof embodiment of casing of the utility model.
Fig. 4 is the local enlarged diagram of B portion among Fig. 3.
Embodiment
The structure of the dustproof preferred embodiment of casing of the utility model, as shown in Figure 3: this dustproof casing has the loam cake 1 of a boxlike and the lower cover 2 of a boxlike.
The bottom of lower cover 2 and sidewall 21 peripheries are surrounded by the flexible glue cover 3 that flexible glue (TPE) makes, extend internally out the termination 32 in " L " cross section, these flexible glue cover 3 end face 12 places towards loam cake 1; Top bar 13 sidewall of the male part 33 that flexible glue overlaps 3 terminations 32 and loam cake 1 sidewall 11 overlaps mutually, and the length of this male part 33 is less than top bar 13 the degree of depth of loam cake 1 sidewall 11 end faces 12.
After the assembling, loam cake 1 fastens mutually with lower cover 2 and by connectors such as buckle or screws they is fixed as a sealed whole body.Please referring to Fig. 4, the recline end face 12 of loam cake 1 sidewall 11 and the male part 33 that flexible glue overlaps 3 terminations 32 of the termination 32 of flexible glue cover 3 stretches in the step 13 of loam cake 1 sidewall 11 on lower cover 2 sidewalls 21; Fin 14 on loam cake 1 sidewall 11 end faces 12 snaps in the termination 32 of flexible glue cover 3 on lower cover 2 sidewalls 21.The male part 33 that flexible glue overlaps 3 terminations 32 is producing compression with top bar 13 sidewall contact position of loam cake 1 sidewall 11 end faces 12.Termination 32 at flexible glue cover 3 forms the tight waterproof of twice annular and the enclosed construction of steam-preventing, can prevent closely that water and steam from entering enclosure interior.
The above only is the utility model preferred embodiment, does not limit the scope that the utility model is implemented with this, and the equivalence of doing according to the technical solution of the utility model and description changes and modification, all should belong to the scope that the utility model is contained.
Claims (2)
