Description

[Detailed Description of the Invention] The present invention relates to a pipe fixing structure for a thin waterproof wristwatch case.

In a conventional wristwatch case side pipe fixing structure, as shown in FIG. 1, the side pipe 5 is adhesively fixed to the side pipe hole of the case 3.

In this case, the tip of the side vibrator 5 protruded into the inside of the body 3, and an adhesive sealant was applied from a portion A in the figure.

However, as waterproof watches have become thinner in recent years, it has become necessary to reduce the distance between the fixed seal part of the upper body 2 and the fixed seal part of the back lid 4, which are installed above and below the side pipe 5. It becomes difficult to make the tip of the side pipe 10 protrude inside the case, so as shown in the embodiment of the present invention shown in FIG. By retracting the upper and lower shells 7 and the back cover 9 to avoid interference, the structure contributes to a thinner structure, but it is difficult to apply the adhesive seal from both the inside and outside of the shell. there were.

That is, not only does the tip of the pipe not protrude from the inside, but also the side pipe fixing hole is in two stages, and the sealing part 8a is deep in the hole, making it impossible to apply adhesive to the necessary part. Not only that, but adhesive often adhered to the inner surface of the hole into which the winding stem was inserted, causing an obstruction.

On the other hand, when the adhesive is applied from the outside of the shell, there is a high risk that the adhesive will spoil the appearance of the shell, resulting in a decrease in yield.

The present invention has been devised to eliminate the above-mentioned drawbacks of the conventional technology.

That is, as shown in FIG. 2, two side pipe fixing holes 8a are provided in the shell 8, and a small hole 8b is provided from below the two-stage hole to be orthogonal to this hole.

This small hole 8b has a smaller hole diameter than the two holes 8a.

Adhesive sealant is applied through this small hole 8b, and the side pipe 10 is sealed and fixed to the two fittings 8a.

Note that 8c in the figure is an annular groove provided on the inner surface of the hole to improve the flow of adhesive.

As described above, the present invention provides a two-stage hole in the watch case for fixing the side pipe, and also provides a small hole perpendicular to the two-stage hole, thereby ensuring that the side pipe can be secured without compromising its functional appearance. Adhesive sealing is now possible, and manufacturing costs can also be reduced.

These efforts have made it possible to create a thin waterproof wristwatch.
