Abstract
The utility model relates to a mechanical structure, to be specific, an anti-seepage sealing structure which comprises a shell body 1 and a shell body 2. The space in between the shell body 1 and the shell body 2 is sealed with a seal ring; an annular seal space is formed in between the shell body 1 and shell body 2. This utility model is characterized in that: a seal gas pocket that can expand after charging is set inside the annular seal space; the seal gas pocket is connected with the air outside the shell body via the breather pipe. As an anti-seepage seal structure, this utility model, which has excellent antiseep capacity, can be applied to the products with high antiseep requirement and can prevent the seepage even under great external pressure.
Description
Technical field
The utility model relates to a kind of mechanical structure, is specially a kind of sealing configuration of leakage proof.
Background technique
The conventional seals mode of structure is: with the seal ring sealing, constitute Seal cage between two housings between two housings; Water-proof watch adopts this mode of structure to make.But thisly rely on the structure that seal ring comes leakage proof fully, to the requirement of seal ring than higher, and if external pressure very big the time, general seal ring just is difficult to play the effect of leakage proof.For this reason, the anti-water depth of water-proof watch generally is no more than 3 meters.
Traditional sealing configuration has had long time without any improvement, and is backward in technique.In view of this, be necessary to design a kind of sealing configuration of new leakage proof.
Summary of the invention
Goal of the invention:
The objective of the invention is to design a kind of sealing configuration of leakage proof, this structure will be applied to the leakage proof product of high request.
Technological scheme:
A kind of sealing configuration of leakage proof, contain housing one and housing two, seal with seal ring between housing one and the housing two, constitute Seal cage between housing one and the housing two, it is characterized in that: Seal cage is placed the sealed air pocket of energy inflation, and sealed air pocket is by breathing pipe and the outer air communication of housing.
Beneficial effect:
A kind of sealing configuration of leakage proof, its leakage proof ability is strong, uses on the leakage proof product of high request, even if outside have very strong pressure also seepage can not occur.
Description of drawings
Fig. 1 is the schematic diagram of leakage proof sealing configuration.
Fig. 2 is that this structure is positioned over work principle figure under the deepwater environment.
Among the figure: 1, housing one, 2, housing two, 3, seal ring, 4, sealed air pocket, 5, breathing pipe, 6, Seal cage, 7, water.
Specific embodiments
A kind of sealing configuration of leakage proof, contain housing 1 and housing 22, seal with seal ring 3 between housing 1 and the housing 22, constitute Seal cage 6 between housing 1 and the housing 22, it is characterized in that: the sealed air pocket 4 that Seal cage 6 is placed the energy inflation, sealed air pocket 4 is by breathing pipe 5 and the outer air communication of housing.
Working principle: when the sealing structure is positioned under the deepwater environment, because the air pressure in the sealed air pocket 4 is less than outside hydraulic pressure, water 7 enters in the sealed air pocket 4 by breathing pipe, sealed air pocket 4 is filled by water 7 and is expanded gradually, because the expansion of sealed air pocket 4 reduces the space of air in the Seal cage 6, the pressure of air will increase in the Seal cage 6, when sealed air pocket 4 expand into to a certain degree, be sealed air pocket 4 internal water pressures when equating with air pressure in the Seal cage 6, sealed air pocket 4 stops water-filling and expands.The outer hydraulic pressure of air pressure and housing equates in this time Seal cage 6, does not have pressure difference inside and outside the seal ring, so the seepage situation can not occur.
This sealing configuration can be applied on the product of various requirement sealing, and as water-proof watch, waterproof mobile phone, other are used for the device of underwater operation, perhaps other need the device of sealing function.
If the sealing structure applications is in the corrosive atmosphere occasion, then the material of sealed air pocket 4 should adopt etch-proof material to make.If the sealing structure applications is in the hot environment occasion, then the material of sealed air pocket 4 should adopt resistant to elevated temperatures material to make.
