Protective cover inflation type seal ring mounting structure

Abstract

The invention relates to a protective cover inflation type seal ring mounting structure which comprises a bottom tank, an upper cover and a sun shade, wherein the upper cover is hermetically mounted at an opening in the upper end of the bottom tank; the sun shade is mounted at the upper end of the upper cover; an inflation type seal ring is hermetically connected between the bottom tank and the upper cover in a compression manner; the inflation type seal ring is communicated with an air bag mounted between the upper cover and the sun shade in an extrusion manner; a clamping plate is packed at an opening of the air bag. The protective cover inflation type seal ring mounting structure is scientific and reasonable in design, simple in structure, and easy to implement, thoroughly solves the poor seal problem caused by that the gap between the upper tank and the bottom tank is non-uniform due to machining error or assembly error.

Description

technical field [0001] The invention belongs to the field of video security monitoring, and relates to a sealing ring, in particular to a protective cover inflatable sealing ring installation structure. Background technique [0002] At present, the outdoor protective cover is generally a flip-up cover structure, and its basic structure consists of a bottom groove block, a bottom groove, an upper cover, a sunshade, a hinge shaft, and a sealing rubber ring. The upper cover and the sunshade are fixed together up and down by screws, and the upper cover and the sunshade can be opened and closed around the hinge shaft. A sealing rubber ring is installed between the upper cover, the bottom groove plug and the assembly of the bottom groove, and the sealing rubber ring is pressed by the lower pressure of the upper cover to play a sealing role. [0003] However, the problems existing in the above-mentioned sealing rubber ring structure are: due to the processing error and assembly er...

AI Technical Summary

Problems solved by technology

[0003] However, the problem with the structure of the sealing rubber ring is that due to processing errors and assembly errors, the gap between the upper cover, the bottom groove, and the bottom groove is uneven, and the cross-sectional shape of the sealing rubber ring is fixed, so it is difficult to adapt to the uneven gap. cause poor seal

In order to make up for the uneven gap problem, the existing protective cover generally adopts the method of increasing the cross-sectional size of the sealing rubber ring to make up for it, but increasing the cross-sectional size of the sealing rubber ring will make the closing of the upper cover very difficult, and even the upper cover cannot be completely closed. , there are gaps in some parts, which is counterproductive; in addition, because the sealing rubber ring is squeezed for a long time and its shape is fixed, it loses its elasticity, which is also the reason for the poor sealing of the protective cover.
