All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 3, in an embodiment of the present invention, a watch hydraulic sealing rubber ring includes: the upper ring body 2 and the lower ring body 1 are concentrically arranged, the upper ring body 2 and the lower ring body 1 are made of rubber materials, the upper ring body 2 is arranged at the upper end of the lower ring body 1, the upper ring body 2 and the lower ring body 1 are both of annular structures, the diameter of the outer ring of the upper ring body 2 is smaller than that of the lower ring body 1, and the diameters of the inner rings of the upper ring body 2 and the lower ring body 1 are the same;

a water avoiding groove 5 arranged along the inner ring surfaces of the upper ring body 2 and the lower ring body 1 is arranged at the position where the upper ring body 2 is connected with the inner ring surface of the lower ring body 1;

the lower end of the inner wall of the water avoiding groove 5 is provided with a water preventing groove 6 which is sunken downwards;

realize the waterproof of wrist-watch special position through the cooperation of upper ring body 2 with lower ring body 1, realize dual waterproof through the trapezium structure of upper ring body 2 with lower ring body 1, during water can flow into the capillary groove 6 of avoiding water groove 5 when the interior anchor ring of upper ring body 2 relaxes and takes place to leak, deposit water through capillary groove 6 and let its natural drying.

The upper groove wall of the water avoiding groove 5 inclines towards the waterproof groove 6 to form a water guide surface 8, and the water guide surface 8 is used for leading water to flow into the water avoiding groove 5 better due to the flow guide of the water guide surface 8 when the inner ring surface of the upper ring body 2 is loosened to cause water leakage.

The lower groove wall of the water avoiding groove 5 is inclined towards the waterproof groove 6 to form a water retaining wall 7, and the water retaining wall 7 is used for preventing water in the waterproof groove 6 from flowing out of the waterproof groove 6.

A waterproof interlayer 9 is arranged in the lower ring body 1, the waterproof interlayer 9 is of an annular structure, the inner ring surface and the outer ring surface of the waterproof interlayer 9 are flush with the inner ring surface and the outer ring surface of the lower ring body 1, the inner ring surface and the outer ring surface of the waterproof interlayer 9 are exposed, and water can be in contact with the waterproof interlayer 9 when water leakage occurs;

the waterproof interlayer 9 is made of water-swelling rubber which can expand 2-3 times when meeting water, and is full of all irregular surfaces, cavities and gaps of the joint, and generates huge contact pressure to thoroughly prevent leakage.

When the waterproof interlayer 9 contacts water, the waterproof interlayer 9 expands, the inner ring of the lower ring body 1 is further reduced or the outer ring area of the lower ring body 1 is enlarged through expansion, and water is further prevented from flowing through the rubber ring.
