Description

Aluminum alloy door with good sound insulation performance

Technical Field

The utility model relates to the technical field of sound insulation, in particular to an aluminum alloy door with good sound insulation.

Background

At present, the door plays a vital role in people's daily life, but the door on the market at present mostly uses timber, aluminum alloy, burglary-resisting door as the main, but can send a large amount of noises along with the use of social development mechanical equipment and modern equipment, if do not carry out noise isolation and can be to our life, work and rest all very big influence, current most door is not enough to satisfy syllable-dividing effect.

SUMMERY OF THE UTILITY MODEL

Based on this, it is necessary to provide an aluminum alloy door with good sound insulation performance aiming at the condition that the door body can not insulate sound, and the influence of noise on the daily life of people can be effectively solved.

The utility model provides a good aluminum alloy door of sound insulation, includes preceding door plant, back door plant, inner core, the inner core has first sound insulation pad, first plank, first glass, second plank and second sound insulation pad from the front to the back in proper order, be provided with the gap between first glass and the second glass, constitute airtight space between first glass, second glass and the frame, airtight space is the vacuum space, the through-hole that vertical direction runs through has all been seted up to first plank and second plank.

Through adopting above-mentioned scheme, the door plant uses the aluminum alloy to make around, more practical and energy-conserving, first sound-proof pad and second sound-proof pad are equipped with to the inner core liam, can reduce vibrations and then noise reduction, the installation of first plank and second plank can the noise reduction, the propagation of noise can be blocked in setting up of airtight space, because sound can't propagate in the medium of vacuum, the consumption of volume can be increaseed in seting up of through-hole, because the straight line of sound is propagated, passes panel + through-hole + panel layer upon layer, and the number of times of refraction increases the sound consumption ratio great, gets into indoor volume and just reduces thereupon, and panel is along with thickness increases, and the sound-insulating coefficient is multiplied to make and arrive indoor noise reduction.

Preferably, the first sound insulating pad and the second sound insulating pad are composite polyethylene sound insulating pads.

Through adopting above-mentioned scheme, thereby the vibrations and the sympathetic response that set up the reduction door body that can be very big of compound polyethylene sound insulation pad greatly reduced the noise entering indoor, compound polyethylene sound insulation pad is lighter moreover, and compound polyethylene sound insulation pad is cheaper.

Preferably, an inner frame is arranged between the first glass and the second glass, and the inner frame and the outer frame are integrally connected.

By adopting the scheme, a gap is reserved after the first glass, the second glass and the inner frame are attached.

Preferably, the front surface and the back surface of the frame are both provided with a sealing groove, and a circle of seal is arranged in the sealing groove.

Through adopting above-mentioned scheme, the setting of seal groove is for the installation sealed pad, the installation of sealed pad makes first glass and second glass laminating on the seal pad, makes vacuum space's gas tightness stronger.

Preferably, the front end surface of the front door panel and the rear end surface of the rear door panel are both provided with handles.

By adopting the scheme, the door handle is arranged to provide an acting point for opening and closing of the door body, and the opening and closing of the door body are easier.

The utility model has the advantages that: the through holes in the wood board can reduce noise, because sound is transmitted linearly and penetrates through the board, the through holes and the cavity layer by layer, the refraction times are increased, the sound consumption is high, the volume entering the room is reduced, and the noise reaching the room is reduced; and airtight space design is the vacuum space, and the reduction that can very big degree spreads into indoor noise into, because the vacuum medium does not propagate the sound, and to a great extent has completely cut off the noise, the installation of compound polyethylene gives sound insulation and fills up makes the speed that the noise propagated diminish, further gives sound insulation to the phenomenon that the noise influences people daily life has been solved.
