In this way, the folding curtain wall mechanism 1 adopts an up-down folding structure, the first noise reduction wall body assembly 3 and the second noise reduction wall body assembly 4 can be folded and unfolded along with the increase of the noise point area range, the noise reduction and sound insulation area of the folding curtain wall mechanism 1 is increased, and vice versa, the first noise reduction wall body assembly 3 and the second noise reduction wall body assembly 4 can be folded when the noise point area range is small, the noise reduction and sound insulation area of the folding curtain wall mechanism 1 is reduced, and the thickness of the noise reduction wall body is increased.

[0054] In an embodiment, the front and back of the first curtain wall frame 301 and the front and back of the second curtain wall frame 401 are detachably buckled with fire-retardant sound-absorbing hole plates 7, the cross-sectional size of the fire-retardant sound-absorbing hole plates 7 is equal to the cross-sectional size of the first curtain wall frame 301 or the second curtain wall frame 401, the four peripheral edges of the inner side of the fire-retardant sound-absorbing hole plates 7 are spaced apart and distributed with positioning columns, and the positioning columns are buckled and matched with the first positioning holes 304 distributed around the peripheral edges of the outer wall surface of the first curtain wall frame 301 or the second positioning holes 404 distributed around the peripheral edges of the outer wall surface of the second curtain wall frame 401. In this way, the fire-retardant sound-absorbing hole plates 7 are a kind of artificial synthetic plates, that is, appropriate fire retardants or inorganic tempered materials are added to the plates to make them have certain fire-retardant properties: if the fire retardant is added, the performance of the plate that is not easy to burn can be increased; if the inorganic tempered material is added, the wear resistance, impact resistance and fire-retardant effect of the plate can be increased.

[0055] At the same time, according to the acoustic principle, grooves are formed on the plate to make it have noise reduction and sound absorption performance, and the sound absorption effect for medium and high frequencies is particularly good.

[0056] In an embodiment, the first curtain wall frame 301 and the second curtain wall frame 401 are centrally fixed with sound insulation plates 10, and the sound insulation plates 10 respectively divide the internal space formed by the first curtain wall frame 301 or the second curtain wall frame 401 and the fire-retardant sound-absorbing hole plates 7 into front cavities and rear cavities of equal size. In this way, the sound insulation plates 10 can not only enhance the overall structural hardness and strength of the first noise reduction wall body assembly 3 and the second noise reduction wall body assembly 4, but also have the effect of sound insulation and noise reduction.

[0057] In an embodiment, the front cavities and the rear cavities are detachably installed with keel frames 8, and each corner of the keel frame 8 is fixed with a plug-in block 801, which is plug-in matched with the first plug-in hole 303 distributed around the peripheral edges of the inner wall surface of the first curtain wall frame 301 or the second plug-in hole 403 distributed around the peripheral edges of the inner wall surface of the second curtain wall frame 401.

In this way, a plurality of sound-absorbing cotton blocks 9 are not only easy to install and remove, but also convenient for workers to check their working life and replace them in time, and can also fill the front cavities or rear cavities to enhance the noise reduction effect of the first noise reduction wall body assembly 3 and the second noise reduction wall body assembly 4.

[0059] In an embodiment, a hinge opening 202 is formed at the upper end side corner position of the trolley shell 201, a plurality of hinge members 209 are distributed on the hinge plate 208, a driving pulley 2010 is hinged on the hinge member 209 near one end of the hinge opening 202, the bottom end of the handle 6 extends into the trolley shell 201 along the hinge opening 202 and is fixedly connected to the driving pulley 2010, and a driven pulley 2011 is hinged on each of the remaining hinge members 209. The bottom end of the driven pulley 2011 is fixedly connected with a flange wheel 2012, and the flange wheel 2012 abuts against the top surface of the suspension plate 205. In this way, in the working state, when the handle 6 is turned to an inclined position relative to the folding curtain wall mechanism 1, the driving pulley 2010 rotates with the handle 6, pulls down the hinge plate 208 through the hinge members 209, drives the hinge plate 208 to press down the driven pulley 2011, and the driven pulley 2011 rotates under pressure, thereby driving the flange wheel 2012 to deflect, pressing down the suspension plate 205, causing the suspension plate 205 to sink, until the wheels 204 descend and extend out of the trolley shell 201, finally enabling the device to move smoothly, reducing the carrying pressure and increasing the flexibility of use.

[0060] Conversely, when the handle 6 is turned to a parallel position relative to the folding curtain wall mechanism 1, the suspension plate 205 is pulled up by external force until the wheels 204 rise and are retracted into the trolley shell 201, finally enabling the device to be stable, facilitating stable operation or storage.

[0061] In an embodiment, a spring 206 is installed on the top surface of the suspension plate 205, the spring 206 is a tension spring 206, the top of the spring 206 is fixed with a pressing plate 207, and the pressing plate 207 abuts against the bottom surface of the hinge plate 208.

[0067] Step four: rotate the handle 6 to the position parallel to the folding curtain wall mechanism 1, until the wheels 204 are raised and withdrawn to the inside of the stroller shell 201;

[0068] Step five: fold the first noise reduction wall assembly 3 upward along the rotating shaft 402 until it is in a vertical position relationship with the second noise reduction wall assembly 4, completing the installation work.
