Hole sound insulation dustproof plugging cover

Abstract

The invention relates to the field of protective covers, in particular to a hole sound insulation dustproof plugging cover which comprises a wall, a first conveying pipeline and a second conveying pipeline. First clamps are arranged on the outer side of a first heat insulation pipe sleeve, second clamps are arranged on the outer side of a second heat insulation pipe sleeve, a mounting clamping block and a first clamping block sleeve the first conveying pipeline, and a second clamping block and a mounting clamping block are connected through a bolt and a nut. The two first clamps and the two second clamps independently clamp the first heat insulation pipe sleeve and the second heat insulation pipe sleeve on the outer side of the conveying pipelines, and the first heat insulation pipe sleeve and the second heat insulation pipe sleeve are easily fixed; and due to the fact that a elastic telescopic rod is internally provided with a spring and has the telescopic function, the amplitude transmitted from the first conveying pipeline to the second clamps on the outer side of the second conveying pipeline can be reduced, noise in the using process is reduced, and the technical problem that when the interval parts of the two conveying pipelines are connected and fixed through connecting rods, vibration is prone to being transmitted is solved.

Description

technical field [0001] The invention relates to the field of protective covers, in particular to a sound-insulating and dust-proof sealing cover for holes. Background technique [0002] At present, the Chinese patent application number: CN201610277735.8 discloses a wall-penetrating pipeline sheath and its installation method, including more than one fixing device erected in the radial direction of the pipeline, and an outer cover is sleeved on the outside of the fixing device. The fixing device includes a thermal insulation cover, a bracket, a support rod and a fixing piece, the thermal insulation cover is set on the pipeline, the bracket is set on the thermal insulation cover, the bracket includes a longitudinal bar and a horizontal bar, A sliding block that can move back and forth is sleeved on the cross bar, one end of the supporting rod is passed through the sliding block, the fixing member is arranged on the free end of the supporting rod, and the fixing member includes...

AI Technical Summary

Problems solved by technology

[0003] Therefore, in view of the above-mentioned problems, the present invention proposes a kind of hole sound insulation and dustproof sealing cover, which solves the problem that there are two conveying pipes with similar intervals passing through on the wall or floor, and using ordinary fixed sheaths, the two It is not easy to fix the heat insulation sleeve on the outside of the pipeline at the interval part of the conveying pipeline. When the interval part is connected and fixed by connecting rods, it is easy to transmit the technical problem of vibration
