The present invention relates to a wrist watch, and more particularly, to a waterproof and insect-proof sealing assembly.

Typically, the watch is equipped with a waterproof and insect repellent function, which is a function to prevent the loss of parts due to the penetration of representative foreign matter into the watch from the outside.

The sealing assembly that performs this function must meet the requirements of impact resistance, airtightness, assembly and elasticity, such that excellent products as well as waterproof and insect repellent function are produced.

Today's watches have brought a lot of technical development, especially the precision of the processing technology of the parts, the miniaturization through the electronic parts are very rapidly improved. Since such watches can be more precise and compact, watches such as gift clocks with precious meanings have been developed to be very thin. However, a thin watch like this gift clock is desired to preserve the life of the clock as permanently as possible so that the precious meaning of the gift does not fade or deteriorate.

Therefore, in order to prolong the life of the clock, the parts should not be accidentally damaged or lost, but above all, the waterproof and the insect proofing should be well treated. After all, it will not be an exaggeration to say that the waterproofing determines the life of the watch, so the waterproofing problem of the normal watch as well as the thin watch is very important. Conventional watch and seal assembly for the waterproof treatment is shown as an example in FIG. 1, when described with reference to FIG.

The inner wall of the annular sealing body 15 located on the inner wall 13 of the case 10 and the outer diameter of the glass 17 are connected. The outer diameter of the rim of the glass 17 is mounted on the flange 15a extending inward in the radial direction of the seal 15. Since the upper end portion of the seal assembly is exposed to the outside, it is easy to contact with foreign substances, so that a substance such as moisture can easily penetrate between the inner and outer diameters of the seal, and the case 10 is assembled during the assembly of the watch. After placing the seal 15 on the stepped portion 13), there is a need to double-assemble the glass 17. In addition, when the watch is impacted from the outside, the glass may be pushed in one direction, that is, a slim phenomenon may occur, thereby deteriorating the waterproof effect or shortening the life of the watch.

Therefore, the present invention has been devised to improve the conventional seal assembly.

It is an object of the present invention to provide a watch seal assembly that is easy to assemble while achieving waterproof and insect proofing of a watch.

Hereinafter, the wristwatch sealing assembly of the present invention will be described in detail with reference to the accompanying drawings.

First, referring to FIG. 2, the glass 20 includes a glass 20, a sealing member 30, and a frame 40 accommodating the glass 20 and the sealing member 30. Referring to FIG. 3, FIG. 3 is a cross-sectional view showing a state in which the sealing assembly 50 of the present invention shown in FIG. 2 is assembled, which is divided by recesses 22 on the circumferential surface 21. As shown in FIG. A glass (20) having a first circumferential surface (23) and a second circumferential surface (24) smaller than the first circumferential surface (23) and larger than the recessed portion (22); An annular sealing member (30) having a flange (31) inserted into the recess (22); It is composed of a frame 40 having an inner wall 41 for receiving and sealing the circumference 31 of the glass 20 and the sealing member 30. 4 shows part A and B shown in FIG. 2 in more detail. It can be seen that the portion A of the glass 20 is composed of the first circumferential surface 23 and the second circumferential surface 24 divided by the central recess 22, and the portion B of the grass 20 is for clarity of explanation. The sealing member 30 integrally formed with the flange 31 is shown as a cross-sectional view shown in the II line direction.

When described in detail with reference to the accompanying drawings the effect of the sealing assembly of the present invention as follows.

First, the sealing member 30 is located on the inner wall 1 of the frame 40 and the glass 20 is covered on the sealing member so that the glass 20 is covered. The sealing member 30 does not come into contact with an external foreign matter, and the flange 31 of the sealing member 30 is inserted into the recessed part 22 of the glass 20 so that foreign matter such as external pressure or moisture may be It can firmly block the penetration. In addition, it is possible to prevent the slim phenomenon of the glass that may occur due to external shocks, even if the external shock is applied, only a very fine degree of sliding phenomenon will be generated sufficient waterproof function.

In addition, with respect to the assembling of the watch, it is mounted between the frame 40 of the watch with the flange 31 of the sealing member 30 is inserted into the recess 22 of the glass 20 to achieve the unity of assembly. Can be. In another embodiment of the present invention, although not shown in the drawings, the A and B portions as shown in FIG. 4 are modified into a glass assembly having a plurality of recesses and a pair of symmetrical flanges or a seal assembly having a plurality of flanges. Since it may be easily modified by those skilled in the art, it will fall within the true spirit and scope of the present invention.

As described above, the watch usually includes glass, so that the peripheral surface of the glass can be used to overcome the limited sealing space, that is, to achieve a waterproof and insectproof function, and to work very quickly during assembly. It will also be a very beneficial contribution to productivity gains.

Claims (1)

In the waterproof and insectproof sealing assembly of the watch, the first circumferential surface 23 and the first circumferential surface 23 divided by the recess 22 on the circumferential surface 21 are smaller than the recess 22. A glass 20 having a large second circumferential surface 24; A sealing member (30) having a flange (31) sealingly coupled to the recess (22); Watch assembly comprising a frame (40) having a circumference of the glass (20) and an inner wall (41) sealingly coupled to receive the sealing member (30).
