Dustproof and soundproof device and its dustproof and soundproof door

Abstract

The invention discloses a dustproof and sound-isolation device and a dustproof sound-isolation door with same. The dustproof and sound-isolation device comprises a machine case, wherein the upper part of one side of the machine case is provided with a through hole; a pressure exerting device and a plug block positioned under the pressure exerting device are arranged in the machine case; the two ends of the plug block are provided with grooves; reset blocks arranged on the machine case wall extend into the grooves; elastic elements A are arranged between the reset blocks and the upper or lower wall surfaces of the grooves; the pressure exerting device comprises a slide rod, a gear and a cam; the bottom of the slide rod is provided with a rack; the gear is positioned under the slide rod and is engaged with the rack; the cam is in coaxial arrangement with the gear; one end of the slide rod is provided with a jacking rod extending out of the through hole; an elastic element B is arranged between the other end of the slide rod and the machine case; after the slide rod is extruded, the extending stroke top end of the cam is in contact with the upper surface of the plug block; and otherwise, the return stroke top end of the cam is in contact with the upper surface of the plug block.

Description

technical field [0001] The invention relates to the household field, in particular to a dustproof and soundproof device and a dustproof and soundproof door. Background technique [0002] The interior door structure is assembled by door casing, door leaf and hardware accessories. The gap between the door leaf and the door casing is mostly sealed with rubber strips, but there is no sealing measure for the gap between the door leaf and the ground. Patent No. "02292837.5", titled "Soundproof Door", discloses a technical solution that can realize the sealing between the bottom of the door leaf and the ground. There is a cavity at the bottom of the door leaf, a control rod is installed in the cavity, and convex teeth are installed on the control rod. , using the convex teeth to squeeze the slider at the lower part of the control rod to seal the door leaf and the ground. This technical solution has the following defects. One, the friction between the protruding teeth of the soundp...

AI Technical Summary

Problems solved by technology

This technical solution has the following defects. One, the friction between the protruding teeth of the soundproof door control lever and the slider is relatively large, and the use of it for a long time will cause noise on the friction surface to affect the rest of the personnel; two. Since the slider is lifted by the elastic part, the elastic part is always in a pulled state, and the elastic part is prone to failure after a long time of use, which is easy to cause the slider to fall, which seriously affects the opening of the door leaf; 3. There is no elastic or Therefore, it is impossible to make the slider stick to the ground, especially when the ground is uneven, it is more likely to be poorly sealed and unable to effectively isolate noise and dust
