[0020] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in Figure 1A structural schematic diagram of a preferred embodiment of the sound-insulating steel-plastic door and window profile provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the structure of the protective shell shown; Figure 3 for Figure 1 The structural schematic diagram of the special-shaped steel shown; Figure 4 for Figure 1 A schematic diagram of the structure of the protective shell shown; Figure 5 for Figure 4 The structural diagram of the dehumidification protection mechanism is shown. The sound-insulating steel-plastic door and window profile includes a protection shell 1, the interior of the protection shell 1 is respectively provided with a mounting groove 4 and a cavity 5, the interior of the mounting groove 4 is embedded with a special-shaped steel 2, the bottom of the special-shaped steel 2 is connected with a support plate 6, the interior of the cavity 5 is provided with a noise reduction mechanism 3, the interior of the noise reduction mechanism 3 is inserted with a dehumidification protection mechanism 7, the noise reduction mechanism 3 is used to cooperate with the protection shell 1 to achieve the purpose of noise reduction, and the dehumidification protection mechanism 7 is used to absorb the moisture inside the noise reduction mechanism 3 to ensure the noise reduction effect.

[0021] The protective shell 1 and the special-shaped steel 2 are manufactured by steel-plastic co-extrusion technology. The inner body of the special-shaped steel 2 can ensure the strength of the protective shell 1 profile, and at the same time improve the fire resistance based on its special-shaped structure. The steel-plastic co-extrusion structure is the basis for realizing the special-shaped inner body. There is no need to install a structural connection between the inner body of the special-shaped steel 2 and the PVC protective shell 1, and they are directly and tightly combined, so that the inner body can be made special-shaped. At the same time, the PVC protective shell 1 can improve the anti-corrosion performance of the steel outside.

[0022] In the specific implementation process, Figure 1 , Figure 4 and Figure 5 As shown, the noise reduction mechanism 3 includes a first connecting block 31 and a second connecting block 33 installed inside the cavity 5. A slide groove is opened inside the cavity 5. The first connecting block 31 and the second connecting block 33 are both inserted into the slide groove. One side of the first connecting block 31 is connected to the first sound-absorbing cotton block 32, and one side of the second connecting block 33 is connected to the second sound-absorbing cotton block 34.

[0023] By inserting the first connecting block 31 and the second connecting block 33 respectively inside the cavity 5, it is convenient to insert the first sound-absorbing cotton block 32 and the second sound-absorbing cotton block 34 into the cavity 5, avoiding the situation where the first sound-absorbing cotton block 32 and the second sound-absorbing cotton block 34 are too soft to be easily inserted.

[0024] refer to Figure 1 , Figure 4 and Figure 5 As shown, the dehumidification protection mechanism 7 includes an insertion rod 72 inserted into the first connection block 31 , and a plurality of air holes are provided on the first connection block 31 , the second connection block 33 and the insertion rod 72 .

[0025] By providing a plurality of air holes on the first connecting block 31, the second connecting block 33 and the inserting rod 72, the contact area with the outside world can be enlarged.

[0026] refer to Figure 1 and Figure 5 As shown, through holes are provided inside the first connection block 31 and the second connection block 33, and a placement rod 71 is inserted inside the through hole, and a water-absorbing material is provided inside the placement rod 71.

[0027] A groove is provided inside the placement rod 71, and a water-absorbing material, such as a silica gel desiccant, an acidic desiccant, a neutral desiccant and an alkaline desiccant, can be placed inside the groove to absorb moisture inside the first sound-absorbing cotton block 32 and the second sound-absorbing cotton block 34 through the air holes on the first connecting block 31, the second connecting block 33 and the insertion rod 72.

[0028] It should be noted that: the protective shell 1 and the special-shaped steel 2 are a steel-plastic co-extruded integral part, the special-shaped steel 2 and the support plate 6 are a cast integral part, the first connecting block 31 and the first sound-absorbing cotton block 32 are adhesively connected, the second connecting block 33 and the second sound-absorbing cotton block 34 are adhesively connected, the first connecting block 31 and the second connecting block 33 are slidably inserted in the slide groove inside the cavity 5, the insertion rod 72 and the first connecting block 31 are an injection-molded integral part, and the placement rod 71 is slidably inserted in the first connecting block 31 and the second connecting block 33 respectively.

[0029] The working principle of a sound-insulating steel-plastic door and window profile provided by the utility model is as follows:

[0030] When in use, by inserting the first connecting block 31 and the second connecting block 33 into the cavity 5 in the protective shell 1 respectively, the first connecting block 31 and the second connecting block 33 respectively drive the first sound-absorbing cotton block 32 and the second sound-absorbing cotton block 34 to enter the cavity 5, so as to avoid the first sound-absorbing cotton block 32 and the second sound-absorbing cotton block 34 from being difficult to enter the cavity 5 due to the material being too soft. In order to avoid the first sound-absorbing cotton block 32 and the second sound-absorbing cotton block 34 being stored in the cavity 5 for a long time, water mist may be generated in the cavity 5 due to the temperature difference. Due to the problem of the first sound-absorbing cotton block 32 and the second sound-absorbing cotton block 34 being affected by moisture, their material and structure may change, resulting in reduced density and weakened sound absorption effect. At this time, the placement rod 71 filled with water-absorbing material can be inserted into the through holes inside the first connecting block 31 and the second connecting block 33 respectively. The water-absorbing material can easily absorb moisture in the gas through the pores to ensure the dryness of the first sound-absorbing cotton block 32 and the second sound-absorbing cotton block 34.
