Description
Technical field
The utility model relates to door and window fields, in particular to a kind of sound-deadening louver.
Background technique
In the industrial production, when can generate biggish noise, especially generating set work, a large amount of noise outflow is had,
Simultaneously because equipment generates a large amount of heat when working, needs to be equipped with the safety that multiple ventilation openings maintain production environment, lead to sound
Sound is propagated outward by ventilation opening, causes noise pollution, influences the routine work of surrounding people, it is therefore desirable to go out to install in ventilation opening
Sound-deadening louver not only may insure that air-flow can smoothly circulate heat dissipation, but also can absorb noise during airflow.
Authorization Notice No. is that the patent of CN203856367U discloses a kind of noise elimination ventilation shutter, including support frame,
It is provided with multi-disc sound absorbing louver piece at equal intervals in parallel on support frame, every sound absorbing louver piece is all by horizontal blind and oblique blinds
It constitutes, one piece of punching weather shield perpendicular to the ground is provided between horizontal blind and oblique blinds；Horizontal blind and oblique hundred
Leaf is internally provided with sound insulating layer, and sound insulating layer is silencing cotton.
But sound absorbing louver piece is welded and fixed with window frame, single louvre blade is difficult to dismounting and change can only when louvre blade damages
Overall pulling down replacement causes to waste.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of blinds of replacement easy to disassemble
Window realizes that single louvre blade can disassemble and install easily and fast.
The above-mentioned technical purpose of the utility model has the technical scheme that a kind of sound-deadening louver,
Including window frame, the rotor plate that is hinged on window frame sides, for rotating the locking mechanism locked after plate closing, multiple being arranged in parallel within
The sound absorbing louver piece of esconson, the esconson are provided with the mounting plate for being used to support sound absorbing louver piece；The noise reduction hundred
Both ends of the blade is provided with side fixed mechanism, and sound absorbing louver piece upper end is provided with top fixed mechanism；The side is fixed
Mechanism includes fixed cage plate on a mounting board, offsets with sound absorbing louver piece side plate passes through cage plate and side plate rotation company
The locking screw rod connect, the locking screw rod are threadedly coupled with cage plate；Top fixed mechanism includes being slidably arranged in window frame or installation
Sliding part on plate, the top pressing board abutted below sliding part with sound absorbing louver piece, both ends are separately connected sliding part and press
The reset spring of plate.
When needing to dismantle, unlock locking mechanism is rotated further by locking screw rod, makes side plate first by the opening of rotor plate
It is detached from sound absorbing louver piece；Sliding part is further slided later, is no longer abutted so that top pressing board leaves from sound absorbing louver piece upper end, i.e.,
Sound absorbing louver piece can be taken down from mounting plate, remove window frame；Also sound absorbing louver piece is only needed to hang on a mounting board when blinds is installed,
Noise elimination blinds is carried out with the side plate of two sides to compress fixation, mobile sliding part makes top pressing board abut sound absorbing louver piece top,
Plate closing is rotated, locking mechanism locks rotor plate.Whole dismounting installation process is easy to operate, convenient for safeguarding.
Further, the sliding part includes standing screw and the swivel nut that is threaded on standing screw, the fixation
Screw rod one end is fixed with sliding block, and horizontally disposed sliding slot, the reset spring both ends point are offered on the window frame or mounting plate
It is not fixed with top pressing board and swivel nut.
The restoring force of such adjustable reset spring spring when top pressing board abuts sound absorbing louver piece, to change and disappear
The abutting degree of sound louvre blade, and with rotary threaded sleeve top pressing board can be separated with sound absorbing louver piece when top pressing board is mobile.
Further, sheet rubber is fixed on the end face that the side plate is abutted with sound absorbing louver piece.
Sheet rubber has certain elasticity, sound absorbing louver piece is abutted tighter.
Further, the sound absorbing louver piece includes that bottom has a limiting slot, the slot bottom width and mounting plate of limiting slot
It is of same size.
Such sound absorbing louver piece, which is placed on mounting plate, can limit the lateral shift of sound absorbing louver piece.
Further, the sound absorbing louver piece includes shutter frame, the silencing cotton being filled in shutter frame, is inserted into shutter frame
The limit stud for compressing the shutter cover of silencing cotton and being threadedly coupled across shutter frame with shutter cover.
By the split settings of shutter cover and shutter frame, the silencing cotton inside sound absorbing louver piece is facilitated to can be regularly replaced,
Ensure to maintain the erasure effect of sound absorbing louver piece.
Further, solid cotton stalk is fixed on the shutter cover.
Silencing cotton is whole bulk identical with shutter cover size, offers multiple restrictions along the vertical direction on silencing cotton
Hole, solid cotton stalk insertion limits hole and silencing cotton is auxiliarily fixed when under shutter cover lid.
Further, the solid tapered setting of cotton stalk.
It is convenient to consolidate in cotton stalk insertion restriction hole.
Further, the locking mechanism includes the shaft being rotatablely connected with window frame, the block being fixed in shaft, covers
Both ends are separately connected the torsional spring of block and window frame in shaft.
By the setting of locking mechanism, when block is not by external force, due to the active force of torsional spring, block holding level is connected to
Rotor plate is locked on the outside of rotor plate.
In conclusion the utility model has the following beneficial effects:
By the combination of mounting plate, side fixed mechanism, top fixed mechanism and rotor plate, realize that sound absorbing louver piece can
It is stably mounted at esconson, and the disassembly of sound absorbing louver piece is simple, facilitates the replacement of sound absorbing louver piece；Pass through sound absorbing louver
The split settings of piece realize that silencing cotton can be replaced, it is ensured that the erasure effect of sound-deadening louver is preferable.
