Description

Sound insulation device for lower opening of door

Technical Field

The utility model relates to an architectural decoration field especially relates to a door end opening noise insulation.

Background

The door is a main way for transmitting noise into the room, and in places with relatively high requirements on sound insulation, such as high-grade hotels, meeting rooms and the like, footsteps and talk sound passed by guests and sound pushed by corridor cars, series of noises such as carpet cleaning and the like are generally transmitted into the room through gaps below the door to form noise, so that normal life is influenced. For this reason, at present, a section of rubber strip is usually installed at the bottom end of the door leaf to seal the gap between the lower opening of the door leaf and the ground. The method can reduce the noise transmission to a certain extent, but if the rubber strip is too tight, the resistance of the rubber strip to the ground friction easily causes the door leaf to be inconvenient to close; if the rubber strip is too loose, the better sealing and sound insulation effect cannot be achieved. Meanwhile, the rubber strip is easy to wear due to the friction between the rubber strip and the ground.

In order to solve the problems, a Chinese patent with publication number CN104533259B discloses a sound insulation device for a lower opening of a door, which comprises a cross beam, a push rod, a rubber strip clamping piece and a sound insulation rubber strip, wherein the side of the cross beam, which faces the opening side of a door leaf, is provided with a protruding touch point; the upper end of the push rod is provided with a spring stop block, a spherical contact pressure head is arranged above the spring stop block, the lower end of the push rod penetrates through the lower end face of the door leaf, and the push rod is also sleeved with an adhesive tape reset spring; the number of the push rods is equal to the number of the arc-shaped notches on the lower side of the cross beam, and the spherical contact pressure heads above the push rods are pressed against the corresponding arc-shaped notches on the lower side of the cross beam; the adhesive tape clamping piece is arranged on the lower side of the door leaf and is fixed at the lower end of the push rod; the upper end of the sound insulation rubber strip is fixed in the rubber strip clamping piece. The closed sound insulation device for the lower opening of the door has the advantages of no influence on the closing operation of the door leaf, good closed sound insulation effect, difficult abrasion and the like.

Above-mentioned scheme has solved present door leaf underground installation rubber strip, and the rubber strip tension leads to the door leaf closed inconvenient easily and if the rubber strip is too loose then can not play better closed syllable-dividing effect and rubber strip still very easily makes the problem of rubber strip wearing and tearing with ground friction, but the point of touching of above-mentioned scheme crossbeam stretches out the door leaf and opens one side, and life is short and there is the potential safety hazard.
