Description
Technical field
This utility model relates to a kind of article of everyday use, particularly relates to a kind of two-layer equation cup cover for water cup.
Background technology
Water tumbler is article conventional during people live, and there are the following problems for existing water tumbler: the poor sealing performance between bowl cover and the cup of water tumbler, causes the liquid seepage in water tumbler out, and impact uses, but also affects the heat-insulating property of water tumbler.
It is, therefore, desirable to provide a kind of new cup cover for water cup, it is possible to make to closely cooperate between bowl cover and cup, be effectively improved the sealing property of water tumbler.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of two-layer equation cup cover for water cup, it is possible to makes to closely cooperate between bowl cover and cup, is effectively improved the sealing property of water tumbler.
A kind of two-layer equation cup cover for water cup that this utility model provides, including outer cover, the inner cap body of column structure, rotating shaft and bearing, described inner cap body is coaxially disposed in outer cover, described outer cover is pivotally coaxially coated at the upper end of described rotating shaft, described bearing outside is in the upper end of rotating shaft and is fixedly installed on outer cover, and the lower end of described inner cap body and rotating shaft is fixedly and coaxially connected；
The end, upper end of described inner cap body extends radially outward the edge of a wing forming circulus, and the lower surface on the described edge of a wing is provided with elastic packing assembly；
Described elastic packing assembly includes sealing ring and spring, the lower surface of described sealing ring is provided with the seal groove that bottom surface is globoidal structure, being provided with elastic sealing gasket in described seal groove, the upper end of described spring is fixing with the lower surface on the edge of a wing to be connected, and the lower end of described spring is fixing with sealing ring to be connected.
Further, described elastic sealing gasket is rubber gasket.
Further, the sidewall of described inner cap body is fixedly installed the diaphragm seal of multiple circulus.
The beneficial effects of the utility model: two-layer equation cup cover for water cup of the present utility model, it is possible to make to closely cooperate between bowl cover and cup, are effectively improved the sealing property of water tumbler, and then reduce the heat exchange in water tumbler and outside water tumbler, improve the heat-insulating property of water tumbler.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further described:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, as shown in the figure, a kind of two-layer equation cup cover for water cup that this utility model provides, including outer cover 1, the inner cap body 8 of column structure, rotating shaft 10 and bearing 9, described inner cap body 8 is coaxially disposed in outer cover 1, described outer cover 1 is pivotally coaxially coated at the upper end of described rotating shaft 10, and described bearing 9 is coated at the upper end of rotating shaft 10 and is fixedly installed on outer cover 1, and the lower end of described inner cap body 8 and rotating shaft 10 is fixedly and coaxially connected；
The end, upper end of described inner cap body 8 extends radially outward the edge of a wing 3 forming circulus, and the lower surface on the described edge of a wing 3 is provided with elastic packing assembly；
Described elastic packing assembly includes sealing ring 2 and spring 6, the lower surface of described sealing ring 2 is provided with the seal groove 4 that bottom surface is globoidal structure, it is provided with elastic sealing gasket 5 in described seal groove 4, the upper end of described spring 6 is fixing with the lower surface on the edge of a wing 3 to be connected, the lower end of described spring 6 is fixing with sealing ring 2 to be connected, in use, inner cap body is embedded in cup, outer cover is connected with cup outside screw, sealing gasket and seal groove are under the effect of elastic pre-stress, can make to coordinate between bowl cover and cup tightr, thus being effectively improved the sealing property of water tumbler, and then the heat exchange in minimizing water tumbler and outside water tumbler, improve the heat-insulating property of water tumbler.
In the present embodiment, described elastic sealing gasket 5 is rubber gasket, draws materials conveniently, with low cost.
In the present embodiment, the sidewall of described inner cap body 8 is fixedly installed the diaphragm seal 7 of multiple circulus, and this diaphragm seal adopts elastomeric material to make equally, when inner cap body embeds cup, diaphragm seal and cup medial wall can be made to fit tightly, thus what formed between bowl cover and cup is multi-sealed.
What finally illustrate is, above example is only in order to illustrate the technical solution of the utility model and unrestricted, although this utility model being described in detail with reference to preferred embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent replacement, without deviating from objective and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
