Abstract
The invention relates to a protective cover with anti-dewing function, which is composed of an outer cover, an inner cover and a transparent cover. The transparent cover is fixedly arranged at the lower part of the inner cover, the outer cover is sheathed at the upper part of the inner cover, an air exhaust hole is arranged at the upper end face of the inner cover, and a pressure valve is arranged at the upper end face of the air exhaust hole in a covering manner. The pressure valve is articulated on a fixed rack by a pressure valve handle, the fixed rack is fixedly arranged on the upper surface of the inner cover, a pressure spring is arranged on the pressure valve in a pressing manner, and the other end of the pressure spring is fixedly arranged with the fixed rack. Hot air at the inner part of the protective cover can be effectively discharged, so as to lower the humiture of air at the inner part of monitoring equipment, thereby not generating mist on the transparent cover, improving the monitoring quality and ensuring normal as well as reliable running of a cloud deck. The protective cover has the characteristics of reasonable design, high safety, good reliability and wide application range.
Description
Technical field
The present invention relates to field of video monitoring, especially a kind of protective cover with anti-dewing function.
Background technology
Existing watch-dog all is installed in outdoor by protective cover, because outdoor weather is various, the situation of blowing and raining is comparatively common, therefore in order to guarantee that watch-dog can normally move, just must make the protective cover of watch-dog have high sealing, thereby prevent that rainwater or dust etc. from entering the inner picture quality that influences of watch-dog.The sealing property of present most of protective covers is all very high, and degree of protection reaches IP66, IP67 substantially, can play waterproof action.Yet, precipitate cooling and sleety weather can make the protective cover internal-external temperature difference strengthen, because its internal work temperature is very high, and ambient temperature is very low, therefore one deck fog will soon condense on the translucent cover of protective cover bottom, cause monitoring image fuzzy even do not have image, influence monitoring effect.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of reasonable in design, easy for installation, can guarantee that monitoring effect has the protective cover of anti-dewing function clearly.
The present invention solves its technical matters and is achieved through the following technical solutions:
A kind of watch-dog protective cover with anti-dewing function is made up of outer cover, inner cover and translucent cover, and translucent cover is installed in the inner cover bottom, and outer cover is set in inner cover top, it is characterized in that: be shaped on a vent port in the upper surface of inner cover; Adorn one at the upper end of this vent port cover and press valve, this pressures valve presses valve handle to cut with scissors to be loaded on the fixed mount that the inner cover upper surface installed by one, press-fits the stage clip that the other end and fixed mount install on this pressure valve.
And, paste a rubber rubber cushion at the bottom surface of pressing valve.
And, on the fixed mount that upper surface installed of described inner cover a rotating shaft being installed, compression spring sleeve is contained in this rotating shaft, presses valve handle to be vertically mounted in the rotating shaft.
Advantage of the present invention and beneficial effect are:
1. the present invention is fixed with a fixed mount in the upper surface of inner cover, one rotating shaft that is set with stage clip on it is installed on this fixed mount, the vertical pressure valve handle of installing in this rotating shaft, this pressure valve handle front end installs one and presses valve, this pressure valve seal is fitted in the upper surface of inner cover vent port, and the stage clip of rotating shaft institute suit is fitted in the upper surface of valve.When the sudden change of watch-dog, make the internal work temperature very high, when ambient temperature is very low owing to outdoor temperature, according to the principle of expanding with heat and contract with cold, inner swelling heat air can be discharged from press valve, the air temperature difference of watch-dog inside and outside is dwindled, so translucent cover can not produce fog.
2. the present invention is pressing contact with the inner cover rubber rubber cushion of pressure valve bottom surface stickup at position of valve.Therefore outdoor clammy air, dust or rainwater etc. can be with not pressing valve to enter protective cover inside, and sealing effectiveness is good, suits to use in outdoor mounted.
3. the present invention can discharge the hot-air of watch-dog inside effectively, make warm and humid the dwindling of air of watch-dog inside, thereby can on translucent cover, not produce fog, improve quality monitoring, guarantee the normal reliable ground operation of The Cloud Terrace, have characteristics reasonable in design, safe and reliable, widely used.

Fig. 1 is the figure that partly cuts open of the present invention;
Fig. 2 is the A portion enlarged diagram of Fig. 1;
Fig. 3 is the vertical view of inner cover among the present invention;
Fig. 4 is the B portion enlarged diagram of Fig. 2.
Embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of watch-dog protective cover with anti-dewing function is made up of outer cover 1, inner cover 2 and translucent cover 3, and translucent cover is installed in the inner cover bottom, and outer cover is set in inner cover top.Because the structure and the annexation of outer cover, inner cover and translucent cover belong to prior art, therefore no longer give unnecessary details.
Innovative point of the present invention is: be shaped on a vent port in the upper surface of inner cover, adorn one at this vent port upper end cover and press valve 4, this diameter of pressing valve is greater than the vent port diameter.Press valve to press valve handle 7 hinges to be loaded on the fixed mount 9 that the inner cover upper surface installed by one, press-fit stage clip 6 on this pressure valve, the other end and the fixed mount of this stage clip install.
Its concrete mounting structure is: the upper surface at inner cover installs fixed mount, and a rotating shaft 8 is installed on this fixed mount, and compression spring sleeve is contained in this rotating shaft.The pressure valve handle is installed in the rotating shaft and perpendicular to rotating shaft, presses valve handle to rotate around the axis.Press valve to be packed in the front end of pressing valve handle, and the stage clip of institute's suit is fitted in the upper end of valve in the rotating shaft.
In order to guarantee sealing effectiveness, paste a rubber rubber cushion 5 at the pressure valve bottom surface of pressing valve and inner cover contact site.
Principle of work of the present invention is:
When wind and rain dashed forward, the internal-external temperature difference of watch-dog can strengthen.Along with the rising of watch-dog internal temperature, the discharge of expanding gradually of its inner hot-air presses valve can follow the elasticity of stage clip slowly to lift.Like this, hot-air will slowly be discharged.
After hot-air has been arranged, press valve can arrive original position with the elastic returning of stage clip again, thereby stop the extraneous air invasion, play the effect of protection.
