Description

M252960 IV. Creative Instructions (1) [Technical Field] The new model relates to a waterproof cushion for a watch bottom case and a case, especially a liquid or gel-like silicone filled between the watch bottom case and the case. After being dried in the annular groove, a waterproof cushion layer is formed between the bottom cover and the case. [Previous technology] At present, the waterproof device between the bottom cover and the case of a general watch is a groove recessed in the bottom cover, and a waterproof gasket made of rubber is embedded in the ring groove. The gasket is pressed between the bottom cover and the case to achieve the purpose of waterproofing. However, the waterproof gasket used above needs to match the shape of the outer groove of the annular groove of the bottom cover. Therefore, each type of watch needs a waterproof outer layer with a different outline shape, that is, each time the manufacturer develops a new shape, Watches' need to design and develop a mold to make the required waterproof ring, thus increasing its manufacturing cost and process troubles. In addition, when the watch is manufactured, it particularly refers to a hand-recorded bottom cover and case made of powder sintering. During the production process, due to the dimensional error of about + 0 · 1 mm from the original design, In the recessed annular groove, the space is narrow and the shape problem cannot be corrected by machining methods such as mechanical grinding. Therefore, when the rubber waterproof gasket is inserted, the waterproof gasket may not completely fill the annular groove of the bottom cover. And a gap is formed between the annular groove and the bottom cover, when it is locked to the bottom end of the case, cannot be fully adhered between the bottom cover and the recording case, so the waterproof function of the watch is often not sure. There is a concern of leakage, and its shortcomings appear.
