Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figures 1-4As shown, this utility model provides a technical solution: a soundproof metal door, comprising: a soundproofing mechanism 1, an auxiliary mechanism 2 provided on the inner side of the soundproofing mechanism 1, the soundproofing mechanism 1 including a door body 11, a metal plate 12 provided on the inner wall of the door body 11, the inner wall of the door body 11 being fixedly connected to the outer side of the metal plate 12, a soundproofing layer 13 and a flame-retardant layer 14 respectively provided on the inner wall of the metal plate 12, the inner wall of the metal plate 12 being fixedly connected to one side of the soundproofing layer 13 and the flame-retardant layer 14, a hollow plate 15 provided on one side of the metal plate 12, the one side of the metal plate 12 being fixedly connected to one side of the hollow plate 15, a rectangular frame 16 provided on one side of the door body 11, the one side of the door body 11 being fixedly connected to one end of the rectangular frame 16, a knob 18 provided on the inner side of the rectangular frame 16, the inner side of the rectangular frame 16 being rotatably connected to the outer side of one end of the knob 18, and one side of the knob 18 being... A movable rod 17 is provided, and one side end of the knob 18 is in movable contact with the inner wall of the movable rod 17. A magnet 111 is provided on the top side of the movable rod 17, and the top side of the movable rod 17 is fixedly connected to the bottom side of the magnet 111. One top end of the magnet 111 is fixedly connected to the inner side of the rectangular frame 16. An L-rod 19 is provided on the inner side of the rectangular frame 16, and one end of the L-rod 19 is fixedly connected to the inner side of the rectangular frame 16. A magnet 110 is provided on the top side of one end of the L-rod 19, and the top side of the L-rod 19 is fixedly connected to the bottom side of the magnet 110. The top side of the magnet 110 is attracted to the bottom side of the movable rod 17. A frame 112 is provided on one end of the movable rod 17, and one end of the movable rod 17 is fixedly connected to the top side of the frame 112. A sealing plate 113 is provided on the inner side of the movable rod 17, and the inner side of the movable rod 17 is fixedly connected to the outer side of the sealing plate 113.

[0026] In this embodiment, when this type of soundproof metal door is used, firstly, two metal plates 12 are designed in the door body 11, and the two metal plates 12 are connected by a hollow plate 15. Moreover, the inner walls of the two metal plates 12 are both equipped with a sound insulation layer 13 and a flame retardant layer 14. The sound insulation layer 13 is made of polyurethane, and the flame retardant layer 14 is made of phosphorus trichloride. The polyurethane sound insulation layer 13 on the inner wall can absorb and attenuate sound waves, greatly reducing noise transmission. The flame retardant layer 14, made of phosphorus trichloride, can improve the fire resistance of the door body 11. The hollow plate 15 has multiple concave holes. The concave hole design can form an air cavity, increasing the reflection and scattering of sound waves in the hollow plate 15, making it easier for sound waves to be attenuated and absorbed, thereby further improving the sound insulation performance. At the same time, it reduces the weight of the door body 11, making it easier to install and use, and may also reduce transportation costs.

[0027] Secondly, after the door 11 is installed, there will be a gap between the bottom of the door 11 and the ground during the closing process. Therefore, by turning the knob 18, the lever on the knob 18 will exert an external force on the moving rod 17, causing it to move up and down in its original position. The moving rod 17 has a frame 112, and the inner side of the frame 112 has a sealing plate 113. As it moves down, the sealing plate 113 will come into contact with the ground, and the side of the sealing plate 113 will block the gap. This can effectively prevent sound waves from propagating through the gap, further improving the sound insulation performance of the door 11 and ensuring a quiet indoor environment. In addition, after the moving rod 17 moves down, it will attract the magnet 110 on the L rod 19, ensuring that it is stable in the moved position. At the same time, when the moving rod 17 is in its original position, it will attract the magnet 110, preventing it from moving up and down arbitrarily.

[0028] Example 2

[0029] like Figure 4 As shown, the auxiliary mechanism 2 includes a fixed rod 21, one end of which is provided with a roller 22. One end of the fixed rod 21 is movably connected to one end of the roller 22. A movable rod 17 is provided on the outside of the roller 22. The outside of the roller 22 is slidably connected to the inside of the movable rod 17. The other end of the fixed rod 21 is fixedly connected to one side of the door body 11.

[0030] In this embodiment, the roller 22 installed on the inner side of the moving rod 17 can significantly reduce the friction of the moving rod 17 during its up-and-down movement, making the movement smoother. At the same time, it restricts the path of movement to prevent movement and wear on other components. The connecting end of the roller 22 has a fixing rod 21, which supports the roller 22 to prevent it from shaking or falling off, thereby improving the reliability of the entire component linkage.
