A waterproof, antifreeze and antifog photographic lens

Abstract

The invention discloses a waterproof, anti-freeze and anti-fog photographic lens. The invention adopts a clearance fit connection assembly to connect the lens seat and the housing. In a low-temperature environment, in order to prevent water droplets from freezing on the lens, a controller controls the heating plate to heat. And the gap fit connection components are heated through the heat conduction ring, so that the gap fit connection components are heated and expanded, and then the gap fit connection components are converted into interference fit connections to ensure the temperature inside the lens and prevent water droplets from freezing on the inside and outside of the lens. In the summer when the height is high, gaps can be provided on the gap fit connection assembly to realize external heat dissipation inside the lens. In addition, even if there is moisture inside, it can also be discharged through the gap in sunny days to ensure the service life of the lens; the present invention is provided with The heating plate can not only prevent the front lens from being fogged, but also provide heat to prevent the lens from being frozen in cold weather.

Description

technical field [0001] The invention relates to the technical field of photographic equipment, in particular to a waterproof, antifreeze and antifog photographic lens. Background technique [0002] Generally speaking, the lens on the market has a single function, it can only provide the imaging function, it cannot effectively deal with harsh environments, it cannot be waterproof, and it cannot solve the situation of the lens being fogged by itself. , Airflow or water droplets are attached to the lens, and the water droplets will freeze. In this way, in rainy and snowy days in winter, the lens is easily covered with ice, which makes the camera unusable. If the lens is simply heated inside the lens Due to the low temperature in winter, it needs to be fully enclosed to prevent the heat from dissipating. In this case, when it is used in summer or sunny days, once there is moisture inside, it is not only difficult to The discharge will have a great adverse effect on the lens, an...

If the lens is simply heated inside the lens Due to the low temperature in winter, it needs to be fully enclosed to prevent the heat from dissipating. In this case, when it is used in summer or sunny days, once there is moisture inside, it is not only difficult to Discharge will have a great adverse effect on the lens, and when the temperature is high in summer, it is difficult to achieve heat dissipation
