The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses ventilation noise elimination shutter.

As shown in fig. 1 and 2, a ventilation and noise elimination shutter comprises a window frame 1, wherein mounting plates 2 matched with the inner edge of the window frame 1 are relatively and fixedly connected to the window frame 1 along the vertical direction, three blades 3 are connected between the two mounting plates 2, the three blades 3 are uniformly distributed between the two mounting plates 2 along the vertical direction, two ends of each blade 3 are respectively and fixedly connected with a sliding block 4, three sliding grooves 5 matched with the sliding blocks 4 are respectively formed in the two mounting plates 2, the six sliding blocks 4 are respectively and correspondingly connected in the six sliding grooves 5 in a sliding manner, iron blocks 6 are fixedly connected to the sliding blocks 4, limiting grooves 7 are formed in the groove walls of the sliding grooves 5, magnetic blocks 8 matched with the iron blocks 6 are fixedly connected to the limiting grooves 7, and the magnetic blocks 8 partially extend out of the limiting grooves 7; when the blade 3 and the mounting plate 2 are abutted against each other, the iron block 6 and the magnetic block 8 are contacted and adsorbed with each other. Therefore, magnetic adsorption force exists between the magnetic block 8 and the iron block 6, the possibility that the blade 3 is separated from the sliding groove 5 is reduced, and the connection strength between the blade 3 and the mounting plate 2 is improved; when needs are dismantled blade 3, the staff can lift blade 3 off from between mounting panel 2 through the mode of drawing blade 3 to the staff restores or changes blade 3, thereby has promoted blade 3's restoration efficiency.

As shown in fig. 3 and 4, a limiting plate 9 for closing the sliding groove 5 is connected to the indoor end surface of the mounting plate 2, two mounting bolts 10 penetrate through the limiting plate 9 in the vertical direction and are in threaded connection with the limiting plate, two mounting grooves 11 matched with the mounting bolts 10 are formed in the indoor end surface of the mounting plate 2, the two mounting bolts 10 are respectively in threaded connection with the two mounting grooves 11, an indicating rod 12 arranged in the horizontal direction is fixedly connected to the end surface of the limiting plate 9 facing the blade 3, an indicating block 13 is fixedly connected to the indoor end surface of the blade 3, and an indicating groove 14 matched with the indicating rod 12 is formed in the end surface of the indicating block 13 facing the indicating rod 12; when the indicating rod 12 is tightly pressed in the indicating groove 14, the two mounting bolts 10 are respectively aligned with the two mounting grooves 11. Therefore, the limiting plate 9 has the function of indicating and limiting, and the possibility that the blade 3 falls off from the mounting plate 2 under the action of external force is reduced; when the limiting plate 9 is required to be installed, the worker can align the mounting bolt 10 with the mounting groove 11 quickly and conveniently by abutting the indicating rod 12 in the indicating groove 14, so that the mounting efficiency of the limiting plate 9 is improved.

As shown in fig. 4, three blade 3 is connected with connecting plate 15 on the terminal surface on ground respectively, it inhales the sound cotton 16 to bond on the terminal surface that connecting plate 15 deviates from blade 3, connecting plate 15 is along four inserted blocks 17 of four corner fixedly connected with on blade 3's the terminal surface, four with inserted block 17 assorted slots 18 have been seted up on blade 3, four inserted blocks 17 are pegged graft respectively in four slots 18, blade 3 is connected with three inserted bars 19 on the indoor terminal surface of orientation, the slot 18 of three confession inserted bar 19 grafting has been seted up on blade 3, three slot 18 communicates with the jack 20 that corresponds respectively, seted up respectively on the inserted block 17 with inserted bar 19 assorted joint groove 21, three inserted bar 19 supports tightly respectively in the three joint groove 21 that corresponds. Therefore, the sound absorption cotton 16 has the noise reduction effect, outdoor noise is diffused to the indoor after being absorbed by the sound absorption cotton 16 after passing through the louver, and the noise reduction capability of the blade 3 is improved; the arrangement of the inserted link 19 has the function of limiting displacement, so that the connecting plate 15 is not easy to separate from the blade 3 under the action of external force, and the connecting strength between the connecting plate 15 and the blade 3 is enhanced; when sound cotton 16 is inhaled to needs to be changed, the staff can draw 19 at first and take out the inserted bar 19 from joint groove 21, draw connecting plate 15 then and lift off connecting plate 15 from blade 3 to inhale sound cotton 16 on the connecting plate 15 and restore or change in the staff.

As shown in fig. 4, the window frame 1 is fixedly connected with a dust screen 23 for sealing the window frame 1, and the end surface of the dust screen 23 departing from the window frame 1 is fixedly connected with an insect-proof screen 22 matched with the window frame. Therefore, the arrangement of the insect-proof net 22 reduces the possibility that outside flying insects enter the room through the blind window, thereby improving the insect-proof performance of the blind window; the arrangement of the dustproof net 23 reduces the possibility that dust directly enters the room; when the insect-proof net 22 is damaged, the arrangement of the dust-proof net 23 further improves the insect-proof performance of the blind.

The implementation principle of the embodiment of the application is as follows: when blade 3 needs to be dismantled, the staff at first rotates construction bolt 10 and unloads limiting plate 9 from the lateral wall of mounting panel 2, overcome the magnetic attraction between magnetic path 8 and iron plate 6 through the mode of drawing blade 3, unload connecting plate 15 from between mounting panel 2, later draw the inserted bar 19 and take out inserted bar 19 from joint groove 21, draw connecting plate 15 at last and unload connecting plate 15 from blade 3, so that the staff repairs or changes blade 3, thereby the dismantlement efficiency of single blade 3 has been promoted.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
