Simple dust-proof and sound-proof installation and its dust-proof and sound-proof door

Abstract

The invention discloses a simple dust-prevention and sound-insulation device and a door equipped with the same. The simple dust-prevention and sound-insulation device comprises a machine shell, wherein a through hole is formed in the upper part of one side of the machine shell; a pressurizing device and a plunger block are arranged in the machine shell; the plunger block is located under the pressurizing device, grooves are formed in two ends of the plunger block, reset blocks which are arranged on the wall of the machine shell and stretch into the grooves, and elastic components A are arranged between the reset blocks and the upper or lower wall surfaces of the grooves; the pressurizing device comprises a slide rod; wheels are arranged below the front and rear ends of the slide rod, an ejector rod stretching out of the through hole is mounted at one end of the slide rod, and an elastic component B is arranged between the other end of the slide rod and the machine shell; a low plane and a high plane are sequentially arranged on the upper surface of the plunger block along the rolling directions of the wheels, after the slide rod is extruded, the wheels are located on the high plane, and otherwise, the wheels are located on the low plane.

Description

technical field [0001] The invention relates to the household field, in particular to a simple dustproof and soundproof device and a dustproof and soundproof door thereof. 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 teet...

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
