Abstract
The utility model discloses a waterproof potentiometer which comprises a housing, an adjusting rod and an outer clamping ring, wherein the adjusting rod passes through a circular hole which is formed in the top of the housing to penetrate into the housing, the part, which is arranged outside the housing and close to the top of the housing, of the adjusting rod is provided with a closed-loop groove A, the periphery of the circular hole in the outer side top of the housing is provided with a groove B, the outer clamping ring is arranged on the junction between the circular hole in the top of the housing and the adjusting rod, the inner side wall of the outer clamping ring is provided with an inward closed-loop projection A, the closed-loop projection A corresponds to the groove A and is clamped into the groove A, the bottom of the outer clamping ring is provided with a downward closed-loop projection B, the closed-loop projection B corresponds to the groove B and is clamped into the groove B, and an inner clamping ring is also arranged inside the housing. By adopting the outer clamping ring and the inner clamping ring as well as the cooperation of the projections on the outer clamping ring and the grooves in the housing, a good waterproof effect can be realized, and the happening probability of the security potential danger can be reduced.
Description
Technical field
The utility model electronic devices and components technology for making field, relates in particular to a kind of waterproof potentiometer.
Background technology
Potentiometer is widely used on the by-pass cock of various electric equipments as a kind of conventional electric elements, current potentiometer is to cover the element in potentiometer by a case mostly, by the adjusting rod stretching in case, current potential is regulated, the scope of using due to potentiometer is wider, likely especially use when operation at sea in the open, yet all can there be certain gap the position of stretching into case due to adjusting rod conventionally, likely water inlet causes the damage of electronic devices and components and malfunctioning when in use, and impact is used.
Utility model content
the utility model provides a kind of waterproof potentiometer, by the double design of outer collar and interior collar, and outer collar projection and the good waterproof action playing coordinating of case upper groove, reduced the probability that potential safety hazard occurs.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of waterproof potentiometer, it is characterized in that: comprise case, adjusting rod, outer collar, described adjusting rod extend in case by being located at case top circular hole, adjusting rod is provided with the groove one of closed loop in the outside part near case top of case, described case outside top circular is provided with groove two, the junction of described case top circular hole and adjusting rod is provided with outer collar, described outer collar madial wall is provided with inside closed loop projection one, with groove one to corresponding and snap in wherein, bottom is provided with downward closed loop projection two, with groove two to corresponding and snap in wherein.
Preferably, described case inner top circular hole and adjusting rod junction are provided with interior collar, and it is enclosed within on adjusting rod, and interior collar cross section is " recessed " font.
Preferably, described outer collar material is engineering plastics, and interior collar material is electro-insulating rubber.
Preferably, the below of described interior collar is also provided with spacer, and it is fixed on adjusting rod.
Preferably, between described groove one and projection one, between groove two and protruding two, all scribble lubricating oil.
The beneficial effect that the utility model reaches is: by the double design of outer collar and interior collar, and outer collar projection and the good waterproof action playing coordinating of case upper groove, reduced the probability that potential safety hazard occurs.
