Description

Technical Field

[0001] This utility model relates to the field of watch technology, and more specifically, to a waterproof insulating ring with multi-level fluororubber sealing. Background Technology

[0002] As wearable devices expand into sports and health monitoring and underwater applications, the waterproof and insulation performance of smartwatches has become a core technical indicator. Although the current waterproof standards can meet the requirements of normal immersion, the traditional single-layer sealing structure has exposed significant defects under dynamic pressure changes (such as swimming and deep diving pressure fluctuations) and extreme environments (seawater corrosion, high and low temperature alternation).

[0003] Current mainstream sealing solutions use single-stage silicone rubber or nitrile rubber rings, which are difficult to balance chemical resistance and mechanical strength. For example, silicone rubber is prone to swelling and deformation after contact with chlorine-containing disinfectants or sweat, leading to seal failure; although nitrile rubber has strong oil resistance, its elastic modulus increases sharply at low temperatures, which may cause cracking.

[0004] Furthermore, existing sealing structures mostly employ single-stage sealing rings, and the accuracy of the compression adjustment of these rings directly affects the waterproofing effect. Insufficient sealing redundancy due to manual assembly deviations is also a common problem, hindering improvements in product yield. Therefore, we propose a multi-stage fluororubber sealing waterproof insulating ring. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model provides a technical solution: a multi-stage fluororubber sealed waterproof insulating ring, including a watch frame 1, a sealing groove 10 provided on the upper surface of the watch frame 1, an annular inner limiting ring 11 fixedly installed on the inner surface of the watch frame 1, a fluororubber sealing ring 22 padded on the upper surface of the inner limiting ring 11, a watch dial 3 provided on the top of the watch frame 1, an insertion clamping ring 31 fixedly installed on the bottom surface of the watch dial 3, the insertion clamping ring 31 abutting against the upper surface of the fluororubber sealing ring 22, and an annular fluororubber ring 32 fixedly installed on the bottom surface of the watch dial 3, the fluororubber ring 32 being located at... The fluororubber ring 32 is adhered to the wall of the sealing groove 10 and fixed with waterproof adhesive, forming the first waterproof barrier between the dial 3 and the frame 1, effectively preventing external moisture from seeping in from the joint. In addition, the fluororubber sealing ring 22 on the inner limit ring 11 and the insertion and tightening ring 31 make a double sealing structure. The fluororubber ring 32 is pressed against the wall of the sealing groove 10, realizing triple sealing, which enables the equipment to resist dynamic water pressure and chemical media corrosion, and ensures the insulation safety of the internal circuit.

[0029] In this embodiment, a through hole 14 is provided on the watch frame 1. A sealing gasket 17 is fixedly installed on the wall of the through hole 14. An outer button 18 is slidably connected inside the through hole 14. A hollow guide block 13 is fixedly installed on the inner wall of the watch frame 1. The hollow guide block 13 is located behind the through hole 14 and communicates with the through hole 14. A fixing ring 171 is fixedly installed on the wall of the through hole 14. The fixing ring 171 is located in front of the sealing gasket 17. A top post 182 is fixedly installed on the rear end face of the outer button 18. The top post 182 passes through the fixing ring 171 and is slidably connected to the fixing ring 171. A spring 183 is wrapped around the top post 182. The rear end of 3 is fixedly installed on the front side of the fixing ring 171. An inner core 2 is provided inside the frame 1. A groove 20 is provided on the inner core 2 opposite to the hollow guide block 13. The hollow guide block 13 is located in the groove 20 and is inserted into the groove 20. An inner button 21 is provided on the rear wall of the groove 20. When the outer button 18 slides inward, it drives the top column 182 to press the inner button 21, so that the outer button 18 can perform the pressing operation while avoiding the risk of water leakage due to gaps. The configuration of the top column 182 and the spring 183 gives the outer button 18 a stable reset feedback, ensuring the reliability and sealing of underwater operation.

[0030] Specifically, both sides of the watch frame 1 are integrally formed with end supports 12, and a touch screen 30 is fixedly installed at the center of the watch face 3. The end supports 12 are used to connect with the watch strap, and the touch screen 30 is used for display and normal touch operation.

[0031] Furthermore, multiple grooves 15 are provided on the wall of the through hole 14, and multiple sliders 181 are fixedly installed on the rear end cylinder of the outer button 18. The sliders 181 are located in the grooves 15 and are slidably connected to the grooves 15, so as to guide the movement of the outer button 18.

[0032] In addition, a speaker slot 16 is provided on the annular side of the frame 1, and a speaker 161 is fixedly installed in the speaker slot 16. The cable of the speaker 161 passes through the rear wall of the speaker slot 16 and is connected to the inner core 2. The part where the cable passes through the rear wall of the speaker slot 16 is also sealed with waterproof glue to achieve the effect of waterproof protection. The entire waterproof insulating ring can be wirelessly charged, reducing the arrangement of charging ports and preventing water from entering the charging part.

[0033] It is worth noting that the fluororubber ring 32, fluororubber sealing ring 22, and sealing gasket 17 can all be made of fluororubber material. Fluororubber material can resist the corrosion of chemical media such as chlorine-containing disinfectants, sweat, and seawater, avoiding swelling and deformation, and extending the life of the seal. At the same time, fluororubber material can maintain elasticity in the range of -20℃ to 200℃, solving the problems of low-temperature brittleness of nitrile rubber and high-temperature softening of silicone rubber, ensuring stable sealing performance in extreme environments. In addition, the insulation resistance of fluororubber material itself is above 10¹²Ω・cm. Finally, the low compression set of fluororubber material is <10%, which allows for precise control of compression in ultra-thin watch bodies, avoiding over-pressure deformation or insufficient sealing, and adapting to the lightweight trend of modern smartwatches.

[0034] Finally, it should be noted that the components involved in this utility model, such as the inner core 2, inner button 21, speaker 161, and touch screen 30, are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0035] During assembly, the multi-stage fluororubber sealing waterproof insulating ring of this utility model is assembled by first placing the inner watch core 2 into the watch frame 1, and then inserting the hollow guide block 13 into the groove 20 of the inner watch core 2 to complete the positioning. Then, the fluororubber sealing ring 22 is placed on the inner limiting ring 11, and then the fluororubber ring 32 is pasted into the sealing groove 10 of the watch frame 1 with waterproof adhesive. At this time, the insertion and tightening ring 31 of the dial 3 is aligned with the fluororubber sealing ring 22 to complete the pressing assembly, forming a triple sealing structure.

[0036] Before use, the watch strap is installed through the end support 12. When the outer button 18 is pressed, the slider 181 of the outer button 18 slides along the guide groove 15. The top post 182 passes through the fixing ring 171 and squeezes the sealing gasket 17. The sealing gasket 17 deforms, so that the top post 182 can be pressed normally onto the inner button 21 to trigger the function. The spring 183 ensures that the outer button 18 is stable after being pressed.
