Abstract
The utility model belongs to a fog-proof transparent cover used for a camera provided with a transparent cover in a monitoring system. The fog-proof transparent cover used for the security camera has the essential scheme by comprising a transparent outer layer optical lens, an inner layer optical lens and an optical lens bracket, wherein an interlayer is arranged in the optical lens bracket and is used for dividing an inner circle of the optical lens bracket into an upper internal concave platform for fixing the outer layer optical lens and a lower internal concave platform for fixing the inner layer optical lens; the outer layer optical lens and the inner layer optical lens are fixedly connected with the optical lens bracket; and an airtight hollow structure is arranged between the outer layer optical lens and the inner layer optical lens. The fog-proof transparent cover can efficiently prevent the lens from being fogged; the optical lens and a cover shell are separated and are respectively formed, thereby easily guaranteeing the optical imaging quality of key positions; the optical lens bracket is not sleeved on a lens any longer, thereby getting rid of the constraint of the lens; and therefore, the selectivity of the shape and the material quality is improved, and the application range is widened.
Description
Technical field
The utility model belongs to the employed antifog translucent cover of the video camera of being furnished with transparent shroud in the supervisory system.
Background technology
For being furnished with the video camera of transparent shroud, its guard shield 1 adopts single ball-type translucent cover or eyeglass as shown in Figure 1 and Figure 2, very easily condenses on the minute surface and adheres to one deck water vapor because the video camera internal-external temperature difference causes when it is exposed in the air, affects image definition.
The utility model content
The purpose of this utility model is to solve the shortcoming that the used transparent shroud of above-mentioned existing video camera exists, and a kind of antifog translucent cover of security protection class video camera that can prevent that ball cover or eyeglass from hazing is provided.
The technical scheme that the utility model adopts is the antifog translucent cover that a kind of security protection class video camera is used, its main points are that it comprises outer optical mirror slip, internal layer optical mirror slip and the optical lens frame of printing opacity, be provided with interlayer in the optical lens frame, the inner ring of optical lens frame is divided into the upper indent platform of fixed outer layer optical mirror slip and fixedly internal layer optical mirror slip and lower indent platform, outer optical mirror slip is fixedly connected with optical lens frame with the internal layer optical mirror slip, is airtight hollow structure between outer optical mirror slip and the internal layer optical mirror slip.
The basic reason that eyeglass hazes is that action of thermal difference causes in Single Medium (such as eyeglass), when there is a fixed difference difference in the both sides of eyeglass, and the airborne water vapor just the larger side of humidity can be condensed, the phenomenon that causes minute surface to haze.Because the utility model adopts the airtight structure of two lens hollow separate between video camera and external environment, so that the temperature transmission is no longer finished by Single Medium, effectively cushion even intercept the process that temperature is transmitted, thus the purpose of realization lens antifogging.
Be filled with inert gas in the hollow structure between outer optical mirror slip and internal layer optical mirror slip.
The inert gas heat conductivility is poor, can play preferably thermal insulation effect.
At the upper indent platform of optical lens frame and the root of lower indent platform the supersonic welding wiring is arranged, below, optical lens frame outside has one to supply in the supporting surface of welding tooling support of optical lens hanger.
When video camera is furnished with infrared light, when having night vision function, because infrared light is through the reflection of guard shield, there is part light can enter camera lens, occur large-scale hickie in the image that camera lens is absorbed or make the exposure of view picture picture, will be enclosed within light blocking ring and prevent on the camera lens that infrared light from entering camera lens, optical lens frame of the present utility model can serve as the light blocking ring use simultaneously by improving.
Optical lens frame is that lighttight material is made when serving as the light blocking ring use, outside at optical lens frame also can be fixed with the guard shield housing, the outer tip end of optical lens frame has a wedge shape flange collar to be connected with the guard shield housing, the internal diameter of optical lens frame is more than or equal to the external diameter of camera lens, and its length surpasses the bottom of video camera built-in light source and the line on camera lens top.
Optical lens frame is independent injection mo(u)lding, then puts into the guard shield housing mould with guard shield housing secondary injection molding as down spare, and the wedge shape flange collar is conducive to the two and firmly connects.
The utility model also has following many advantages except can effectively preventing eyeglass hazing, as: optical mirror slip separates with the guard shield housing, distinguishes moulding, is easy to guarantee the optical imagery quality of key position; Optical lens frame is connected with guard shield housing quadric injection mould, high rejection rate and the cost of labor of avoiding the connected modes such as viscose glue to bring; Optical lens frame be not placed on the camera lens, broken away from the constraint of camera lens, has increased the alternative of shape, material, has widened applicable surface; Optical lens frame has blocked infrared light fully through reflection ray or the refracted ray of eyeglass, thereby has avoided infrared light to make the possibility of camera lens picture exposure.

Embodiment
The following examples can make the professional and technical personnel more understand the utility model, and following embodiment is made amendment, and it all is possible adding and replacing, and does not all exceed protection domain of the present utility model.
The antifog translucent cover that a kind of security protection class video camera is used adopts quadric injection mould and ultrasonic welding method moulding.With the optical lens frame 3 of independent injection moulding, put into the guard shield housing mould with housing together injection mo(u)lding as down spare, ultrasonic soldering optical mirror slip 1 successively then, welding optical mirror slip 2 in being full of the finite space of inert gas.
Outer optical mirror slip 1 or internal layer optical mirror slip 2 are that finishing impression intercepts from the mirror of independent injection moulding, can be processed into arbitrarily different shape, and its optical quality also is easy to guarantee.
