Abstract
The utility model relates to a camera protective cover with the antidewing function, which mainly consists of a protective cover tube body, a front plug, a back plug and a viewing window. The utility model is characterized in that the viewing window is a hollow glass viewing window. Because the camera protective cover of the utility model adopts the double-layer glass viewing window, compared with a traditional protective cover, the utility model has good heat preservation and thermal insulation effects, so the temperature environment of the space inside the camera protective cover is more stable, the severe change caused by external temperature difference is reduced, the occurrence of dew formation of the viewing window can be effectively avoided, and the clear imaging of the camera and a lens in the protective cover can be ensured. In addition, the camera protective cover with the viewing window structure also has better antiultraviolet performance than ordinary protective covers. In addition, the utility model has the advantages of simplicity, compactness, easy installation and low cost, and has good market prospects.
Description
Technical field
The utility model belongs to field of video monitoring, especially a kind of camera protective cover with anti-dewing function.
Background technology
Camera protective cover is to be used for a series products of len and video camera in the video security protection equipment.The fundamental purpose of protective cover form is to be used for len and video camera and provide good light for video camera and camera lens.What can produce certain humidity in installation process in camera protective cover inside, when external temperature is very low, the heat that inner devices such as video camera produce can cause forming one deck and reveal on the form of camera protective cover, this phenomenon is referred to as " dewfall ", cause resulting image blurring unclear, thereby influence monitoring effect.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of camera protective cover with anti-dewing function is provided, and can effectively avoid the generation of form dewfall phenomenon, thereby guarantees picture quality.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of camera protective cover with anti-dewing function mainly is made of guard shield cylindrical shell, preceding stifled, the back stifled form that reaches, and it is characterized in that: described form is the double glazing form.
And described double glazing form adopts the fluid sealant encapsulation to form by double glazing at its interlayer edge.
And, before being flush-mounted in, described double glazing form in the stifled made form groove, on preceding the blocking up in the double glazing form outside, also is embedded with a rubber seal; Adopt glass preform and screw retention on preceding blocking up in the inboard of double glazing form.
And, be filled with inert gas in the interlayer of described double glazing form.
Advantage of the present utility model and good effect are:
This camera protective cover is owing to adopt the double glazing form, compare with traditional protective cover, the fine effect of playing insulation of energy, make the interior space temperature environment of camera protective cover more stable, reduced because of the extraneous temperature difference and caused acute variation, thereby effectively avoid the generation of form " dewfall " phenomenon, guarantee the blur-free imaging of interior video camera of protective cover and camera lens; In addition, the camera protective cover of this window structure also tool than the better ultraviolet resistance of general protective cover; And the advantage that have simple compactness, be easy to install, cost is low has good market outlook.
Description of drawings
Fig. 1 is the perspective view of the utility model camera protective cover;
Fig. 2 is the cut-open view of the utility model camera protective cover;
The cross-sectional view of the double glazing form that Fig. 3 is adopted for the utility model camera protective cover.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
A kind of camera protective cover with anti-dewing function mainly is made of guard shield cylindrical shell 4, preceding stifled 2, back stifled 5 and form 3, also the brim of a hat 1 can be installed in the guard shield barrel front end.Its innovation part is: the form of protective cover is the double glazing form.This double glazing form adopts fluid sealant 12 encapsulation to form by double glazing 13 at its interlayer edge.In the form groove that blocks up before the double glazing form is flush-mounted in, also be shaped on seal groove in preceding stifled inboard, and a rubber seal 6 is installed, be used to the sealing that guarantees that the double glazing form is installed.Before adopting glass preform 7 and screw 11 to be fixed on, blocks up the inner face of double glazing form.Before stifled and the back is stifled installs with screw 8,9 and guard shield cylindrical shell respectively, and all adopt seal with elastometic washer 10 to seal.But filling inert gas also in the interlayer of double glazing form is to have better preventing ultraviolet effect.
This camera protective cover is owing to adopt the double glazing form, external environment condition and protective cover internal insulation can be opened, when ambient temperature is very low, the glass outer temperature reduces, hollow layer is the barrier heat transferred effectively, therefore the inner layer glass temperature can be very not low, guarantees that inner relative temperature can not arrive the dewfall point.
