Problems solved by technology
Due to the smooth surface of the inner wall of the waterproof rubber ring, it is easy to loosen, shift or fall off during the assembly process, so that the waterproof level of this design is only IP65, which affects the quality of the product, and finally makes the product difficult to use during use. Meet customer expectations and even cause undue damage to products
Such a waterproof structure design is very easy to cause product quality degradation due to waterproof problems in areas with a lot of rainfall

The invention discloses a high-airtightness waterproof rubber ring. The waterproof rubber ring comprises a cylindrical rubber mass and a cone-frustum-shaped rubber mass which are connected into a whole. The interior of the waterproof rubber ring is in a hollow cylindrical spiral shape. The inner surface of the waterproof rubber ring and the outer surface of the cone-frustum-shaped rubber mass areprovided with an equidistant internal thread and an equidistant external thread correspondingly. Through the high-airtightness waterproof rubber ring, the waterproof grade of a power source or an applicable lamp can be improved from IP65 to IP 68, the airtightness and waterproofness of the waterproof rubber ring can be enhanced, and assembly and maintenance are facilitated. Accordingly, the performance of the waterproof rubber ring is substantially improved.
Description
technical field [0001] The invention relates to the field of waterproof rubber rings, in particular to a waterproof rubber ring with high sealing performance. Background technique [0002] At present, the inner surface of the waterproof rubber ring is designed with a smooth surface, and the waterproof level is generally IP65. This design not only has a lower waterproof level, but also is easy to loosen and shift when assembled. In the design process of the waterproof structure of the power supply or the application lamp, most of them currently adopt the PG7 to PG12 waterproof joint scheme, so as to play a waterproof role. Due to the smooth surface of the inner wall of the waterproof rubber ring, it is easy to loosen, shift or fall off during the assembly process, so that the waterproof level of this design is only IP65, which affects the product quality and eventually makes the product difficult to use during use. Meet customer expectations and even cause undue damage to pr...
