Abstract
The utility model provides a fastening waterproof mechanism of a threaded stud, which comprises an upper threaded stud, a lower threaded stud, a rubber ring and a screw, wherein the inner wall of the upper threaded stud is provided with threads; the lower threaded stud corresponds to the upper threaded stud; the rubber ring is clamped between the upper threaded stud and the lower threaded stud, and the upper surface and the lower surface of the rubber ring are respectively provided with a circle of lug boss along the edge of the inner diameter of the rubber ring; and the upper threaded stud and the lower threaded stud are fastened together through the screw and apply certain pressure on the lug boss of the rubber ring by screwing the screw, so two spaces are formed by the inner part and the outer part of the fastening waterproof mechanism of the threaded stud, thereby the waterproof aim can be achieved. The fastening waterproof mechanism of the threaded stud achieves the waterproof function and enlarges the application field thereof.
Description
[technical field]
The utility model relates to a kind of screw column retention mechanism, particularly about a kind of thread column fastening waterproof mechanism.
[background technique]
In the existing screw threads for fastening mechanism, it comprises two screw column and a screw, and described screw column inwall is provided with screw thread, above-mentioned two inwalls is had the screw column alignment of screw thread, by the screw thread of above-mentioned screw and the threaded engagement of above-mentioned screw column, thereby above-mentioned two screw column are tightened up.
Yet existing screw threads for fastening mechanism only possesses the fastening function of installation, because the narrow limitation of its structure, when the screw thread of screw and the threaded engagement of above-mentioned screw column, the screw thread of screw and the screw thread of above-mentioned screw column can not be close to fully, therefore circulate in the space between the screw thread of the screw thread that water can be by screw and screw column, therefore, the screw threads for fastening mechanism of prior art does not possess water-proof function.
In view of this, be necessary to provide a kind of screw column retention mechanism in fact, make it possess water-proof function.
[summary of the invention]
The object of the present invention is to provide a kind of screw column retention mechanism, make it possess water-proof function.
For achieving the above object, the utility model provides a kind of thread column fastening waterproof mechanism, and it comprises:
Go up screw column for one, screw column inwall is provided with screw thread on this;
A following screw column, it is corresponding with above-mentioned last screw column;
A rubber ring, it is located between above-mentioned last screw column and the above-mentioned following screw column, and this rubber ring upper and lower surface is provided with a circle protuberance along its internal diameter edge;
A screw, above-mentioned upward screw column and above-mentioned screw column down tighten together by this screw, and make above-mentioned screw column and the above-mentioned time screw column of going up apply certain pressure to the protuberance of above-mentioned rubber ring by turning above-mentioned screw, make this thread column fastening waterproof mechanism inside and outside form airtight two spaces breaking off, thereby reached the purpose of waterproof.
Compared to prior art, thread column fastening waterproof mechanism provided by the utility model has been realized water-proof function, has enlarged its application.

[embodiment]
See also Fig. 1 and shown in Figure 2, it is respectively the overall structure schematic representation and the decomposition texture schematic representation of the utility model thread column fastening waterproof mechanism, and it comprises:
Go up screw column 10 for one, it is located on the product loam cake 1, and screw column 10 inwalls are provided with screw thread (not shown) on this;
A following screw column 20, it is located on the lower cover 2 of product, and it is corresponding with above-mentioned last screw column 10, and is provided with a circle projection 201 along this time screw column 20 external diameter edges;
See also shown in Figure 3, it is rubber ring 3 perspective view of the utility model thread column fastening waterproof mechanism, a rubber ring 3, it is positioned in the projection 201 at above-mentioned screw column 20 external diameter edges down, and this rubber ring 3 is located between above-mentioned last screw column 10 and the above-mentioned following screw column 20, and these rubber ring 3 upper and lower surfaces are provided with a circle protuberance 30 along its internal diameter edge;
A screw 4, the above-mentioned screw column 10 that goes up tightens together by this screw 4 with above-mentioned screw column 20 down, and make the above-mentioned screw column 10 that goes up apply certain pressure with the above-mentioned protuberance 30 of 20 pairs of above-mentioned rubber rings 3 of screw column down by turning above-mentioned screw 4, make this thread column fastening waterproof mechanism inside and outside form airtight two spaces breaking off, thereby reached the purpose of waterproof.
Compared to prior art, thread column fastening waterproof mechanism provided by the utility model has been realized water-proof function, has enlarged its application.
