Description

Waterproof insulating ring sealed by multistage fluororubber Technical Field The utility model relates to the technical field of watches, in particular to a waterproof insulating ring sealed by multistage fluororubber. Background With the expansion of the application of the wearable equipment to sports health monitoring and underwater scenes, the waterproof and insulating properties of the intelligent watch become core technical indexes, and the conventional waterproof standard can meet the conventional water immersion requirements, but under dynamic pressure changes (such as swimming and water drawing and deep diving pressure fluctuation) and extreme environments (seawater corrosion and high-low temperature alternation), the conventional single-layer sealing structure has obvious defects. The current mainstream sealing scheme adopts a single-stage silicone rubber or a nitrile rubber ring, and the chemical resistance and the mechanical strength of the single-stage silicone rubber or the nitrile rubber ring are difficult to be compatible, for example, the silicone rubber is easy to swell and deform after contacting chlorine-containing disinfectant or sweat, so that the sealing is invalid, and the nitrile rubber has strong oil resistance but has suddenly increased elastic modulus in a low-temperature environment, so that the risk of cracks is generated. In addition, the existing sealing structure adopts single-stage sealing rings, the compression amount adjusting precision of the single-stage sealing rings directly influences the waterproof effect, and the problem of insufficient sealing redundancy caused by manual assembly deviation is generally existed, so that the product yield is restricted.
