Abstract
The utility model relates to a sound proof door provided with air grids, which comprises a doorframe and a door leaf. Adjacent vertical edges of the doorframe and the door leaf are articulated together, wherein, the door leaf comprises an inner layer metal plate and an outer layer metal plate; and mineral wool is filled between the inner layer metal plate and the outer layer metal plate. The sound proof door is characterized in that ventilation openings are arranged at the upper part of the outer layer metal plate and the lower part of the inner layer metal plate; the air grids are arranged at the two ventilation openings respectively. A windhole is arranged between the inner layer metal plate and the outer layer metal plate, and the upper end and the lower end of the windhole are respectively communicated with the air grids at the two ventilation openings. The sound proof door achieves not only sound insulation effect but also ventilation effect, and the application range is not limited. The sound proof door is especially applied to various ships.
Description
Technical field
The utility model relates to a kind of soundproof door.Specifically, be the soundproof door that has air grid that can abate the noise, have again performance of ventilating.Be particularly useful on the various boats and ships.
Background technology
Know all that in the shipbuilding industry for eliminating the much noise that equipment produces in the ship's navigation process, the hatch door on the boats and ships mostly adopts the soundproof door with sound insulation property.This soundproof door comprises between an adjacent vertical edge of doorframe and door leaf and the two hinged.Door leaf wherein contains inner layer metal plate and outer metal plates, is filled with damping materials such as rock wool between the ectonexine metal sheet.Though adopt the soundproof door of this structure can satisfy the sound insulation requirement, but because this soundproof door does not have ventilation opening, can only be used in only needs defening effect and does not need in the cabin of the i.e. unmanned work of occasion of ventilation effect, can not be used in not only needs defening effect, but also needs the occasion of ventilating such as conference room, Medical Treatment Room etc. to have in the cabin that the people works, and the scope of application is restricted.
The utility model content
Problem to be solved in the utility model is the defective that overcomes background technology, a kind of soundproof door that has air grid is provided.This soundproof door had not only had defening effect, but also had had ventilation effect, and the scope of application is unrestricted.
For addressing the above problem, take following technical scheme:
The soundproof door that has air grid of the present utility model contains doorframe and door leaf, and is hinged between the adjacent vertical edge of this doorframe and door leaf.Door leaf wherein contains inner layer metal plate and outer metal plates, is filled with rock wool between inner layer metal plate and outer metal plates.Be characterized in that ventilation opening is all arranged at the top of outer metal plates and the bottom of inner layer metal plate, this two ventilation openings place has air grid respectively.Between inner layer metal plate and outer metal plates the air channel is arranged, the upper and lower end in air channel is connected with the air grid at two ventilation opening places respectively.
Take such scheme, have the following advantages:
Because the soundproof door that has air grid of the present utility model is provided with ventilation opening on the top of its outer metal plates and the bottom of inner layer metal plate, all there is air grid at this two ventilation openings place.Between inside and outside layer metal sheet the air channel is arranged, the upper and lower side in air channel is connected with the air grid at two ventilation opening places respectively.Not only had defening effect, but also had ventilation effect, the scope of application is unrestricted.
Description of drawings
Fig. 1 is the soundproof door schematic diagram that has air grid of the present utility model;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, the soundproof door that has air grid of the present utility model contains doorframe 1 and door leaf, and is hinged by hinge 4 between the adjacent vertical edge of doorframe 1 and door leaf.Door leaf wherein contains inner layer metal plate 6 and outer metal plates 2, and 2 of inner layer metal plate 6 and outer metal plates are filled with rock wool.All be processed with ventilation opening on the top of outer metal plates 2 and the bottom of inner layer metal plate 6, this two ventilation openings place is equipped with air grid 31 and 32 respectively.Be processed with air channel 5 at inner layer metal plate 6 and 2 of outer metal plates, the upper and lower end in air channel 5 is connected with the air grid 31 and 32 at two ventilation opening places respectively.
For ease of regulating air quantity, in the air grid 32 of bottom, air quantity governor motion 7 is installed also.
Described inner layer metal plate 6 and outer metal plates 2 all adopt aluminium alloy plate to process.
