[0002] As a commonly used electrical component, the potentiometer is widely used in the adjustment switches of various electrical equipment. Most of the current potentiometers are covered by a case to cover the components in the potentiometer. To adjust the potential, because the potentiometer is used in a wide range, it may be used in the open air, especially when working on water. However, there is usually a certain gap where the adjustment rod extends into the casing, and it may be used during use. Water causes damage and failure of electronic components, affecting use

The invention discloses a waterproof potentiometer. The waterproof potentiometer comprises a shell, a regulating rod and an outer clamping ring, wherein the regulating rod penetrates through a circular hole in the top of the shell and extends into the shell; a closed-loop groove (I) is formed in a part, outside the shell and close to the top of the shell, of the regulating rod; a groove (II) is formed at the periphery of the circular hole in the outer top of the shell; the outer clamping ring is arranged at a joint between the circular hole in the top of the shell and the regulating rod; an inward closed-loop bump (I) is arranged on the inner side wall of the outer clamping ring, corresponds to the groove (I) and is clamped into the groove (I); a downward closed-loop bump (II) is arranged at the bottom of the outer clamping ring, corresponds to the groove (II) and is clamped into the groove (II); an inner clamping ring is arranged inside the shell. By the double design of the outer clamping ring and the inner clamping ring and by the cooperation of the bumps on the outer clamping ring and the grooves in the shell, a good waterproofing effect is achieved, and the probability of occurrence of a potential safety hazard is reduced.
