Abstract
The utility model discloses a kind of water-tight device being applied to cell-phone cover, comprise casing assembly A, casing assembly B, soft rubber circle, square groove and rigid plastic cement holddown groove, described casing assembly A is arranged on the upper end of casing assembly B, described casing assembly B is provided with square groove, described soft rubber circle is fixed on casing assembly A, and described rigid plastic cement holddown groove is arranged on casing assembly B.Waterproof construction installation space of the present utility model is little, greatly saves the space of product, can accomplish light, thin requirement; O-ring seal be with casing assembly A or casing assembly B by mould once injection moulding out, save number of assembling steps, waterproof sealing is in stable condition; After rubber ring press-in fore shell, mutually can be engaged by interference fit tight, less demanding to locking device, save structure space; Adopt transverse shear stress mode, change Impact direction, to the thickness of shell and requirement of strength far below prior art, greatly save the structure space of product.
Description
Technical field
The utility model relates to waterproof technique field, especially a kind of water-tight device being applied to cell-phone cover.
Background technology
In recent years, the smart mobile phone of large-screen more and more receives the favor of consumers in general, and meanwhile, the demand of market to mobile phone protective cover is also more and more vigorous.In the market, the protective sleeve of common protection cell phone appearance is very many, but is suitable for outdoor special waterproof mobile phone protective sleeve, considerably less on market, is difficult to seek.Analyze its reason can find, a waterproofing guaranteeding jacket, the requirement of the IPX7 that particularly meets international standards (1 meter of depth of water soaks 0.5 hour), very high to the requirement of waterproof construction.The product of current industry class, realizing the structure of product casing waterproof employing, general is all adopt upper and lower shell to compress the mode of " o " type silica gel ring at vertical direction, this mode schematic configuration is, needing the centre of A/B two the casing assembly surrounding profiles doing waterproof sealing, place a soft silica gel piece or silica gel annulus, by intensive retaining mechanism (comprising screw, bayonet socket etc.), A, B are compressed silica gel piece or silica gel annulus, thus realize waterproof.The drawback of this mode is, when realizing the waterproof requirement of more than IPX7 rank, the enough intensity of upper and lower shell need be ensured, the unique method realizing this intensity is exactly thickening casing, the overall dimension of product is become very large by undoubtedly, very heavy, follow the fashion current user, under ultra-thin and light demand, seem incompatible with.
Summary of the invention
For the problems referred to above, the utility model aims to provide a kind of water-tight device being applied to cell-phone cover adopting the mode of sidewall transverse shear stress rubber ring.
For realizing this technical purpose, scheme of the present utility model is:
A kind of water-tight device being applied to cell-phone cover, comprise casing assembly A, casing assembly B, soft rubber circle, square groove and rigid plastic cement holddown groove, described casing assembly A is arranged on the upper end of casing assembly B, described casing assembly B is provided with square groove, described soft rubber circle is fixed on casing assembly A, and described rigid plastic cement holddown groove is arranged on casing assembly B.
As preferably, described soft rubber circle is of a size of wide 1.7mm × high 1.6mm.
As preferably, the width of described square groove is 1.5mm, and the degree of depth is 1.8mm.
The space that waterproof construction of the present utility model is arranged is little, greatly saves the space of product, product can be allowed to accomplish light, thin requirement; O-ring seal be with casing assembly A or casing assembly B by mould once injection moulding out, save number of assembling steps, waterproof sealing is in stable condition; After rubber ring press-in fore shell, even without the retaining mechanism of vertical direction, it also can be engaged tightly mutually by interference fit, less demanding to locking device, saving structure space; Adopt transverse shear stress mode, change Impact direction, to the thickness of shell and requirement of strength far below prior art, greatly save the structure space of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1, a kind of water-tight device being applied to cell-phone cover of the utility model embodiment, comprise casing assembly A1, casing assembly B2, soft rubber circle 3, square groove 4 and rigid plastic cement holddown groove 5, described casing assembly A1 is arranged on the upper end of casing assembly B2, described casing assembly B2 is provided with square groove 4, described soft rubber circle 3 is fixed on casing assembly A1, and described rigid plastic cement holddown groove 5 is arranged on casing assembly B2.
As preferably, described soft rubber circle 3 is of a size of wide 1.7mm × high 1.6mm.
As preferably, the width of described square groove 4 is 1.5mm, and the degree of depth is 1.8mm.
Waterproof sealing between casing assembly A1 of the present utility model and casing assembly B2 is pressed in rigid plastic material holddown groove 5 by having flexible elastomeric material, and the mode forming lateral stressed, the mutual extruding of sidewall realizes waterproof; And when assembling, soft rubber circle 3 being pressed in square groove 4, by the interference fit of Width, realizing the sealing of housing component, ensure waterproof effect.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection range that all should be included in technical solutions of the utility model.
