Description

Video Surveillance Cover

technical field

The invention relates to the technical field of video monitoring, in particular to a video monitoring protective cover with good sealing effect.

Background technique

At present, as the most widely used product in the security field, shields can be found at various intersections, streets, communities and indoors. However, the traditional shield structure has not undergone breakthrough changes for more than ten years, and there are still the following problems:

1. Most of the traditional shields adopt the front and rear opening method, and the height of the lower bottom is high, so that the screwdriver needs to be inserted into a certain depth during the disassembly process of the lens, camera and other components. If the lens is large, it is difficult to remove the tools. The side of the lower bottom of the shield invented this time is relatively low, and the components almost completely protrude from the lower bottom after opening the cover, which is very convenient for disassembly and maintenance.

2. The overall structure of the traditional shield is as follows: the bottom is the bottom profile and the die-casting front and rear end covers are screwed directly, the end covers at both ends are higher than the bottom profile, the sealing rubber strip is installed on the outer edge in a saddle shape; the upper cover is folded by an aluminum plate The hinge is connected by a die-casting front cover and the hinge plate installed under the upper cover with stainless steel pins; the fastening clip is installed on the rear end cover, and the hook of the clip hooks the opening of the back end of the upper cover. Through the rotating piece of the clip, the The hook of the clip is retracted into the clip to realize the compression of the upper cover and the upper rubber strip of the lower bottom. Due to the above structure, the rubber strip is in the shape of a saddle, so it is easy to cause poor sealing at the corner of the rubber strip, so that the protection level of the protective cover cannot reach the IP66 standard.

3. Since most of the traditional shields adopt a single-layer glass structure, it is very easy to generate fogging under the condition of good sealing.
