That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a soundproof steel entrance door of the utility model comprises a steel door 1, soundproof cotton 6 and an L-shaped plate 2, wherein the interior of the steel door 1 forms an installation groove with one side and upper and lower openings, a crossbeam 7 is installed in the opening at the upper end of the installation groove, the L-shaped plate 2 is inserted into the interior of the installation groove, the L-shaped plate 2 and the steel door 1 are combined to form an installation cavity with a lower end opening, the soundproof cotton 6 is arranged inside the installation cavity, the lower end of the soundproof cotton 6 protrudes out of the steel door 1, a groove is provided on the soundproof cotton 6, a panel 12 is provided inside the groove, an adjustment mechanism for driving the panel 12 to move up and down is installed at one end of the panel 12, an operating port 5 is provided on the side of the steel door 1 away from the L-shaped plate 2, opposite to the adjustment mechanism; wherein, a rubber layer can be installed on the exposed end of the soundproof cotton, thereby increasing the protection of the soundproof cotton and increasing its service life.

[0022] In this embodiment, the adjustment mechanism includes a screw 13, a rotating ring 15, a fixed plate 16 and a sealed bearing. A first screw hole is provided on the panel 12. One end of the fixed plate 16 is installed on the inner wall surface of the steel door 1, and the other end extends to the top of the first screw hole. The sealed bearing is embedded in the fixed plate 16. One end of the screw 13 is installed in the inner ring of the sealed bearing, and the other end is threadedly connected to the first screw hole. The rotating ring 15 is installed on the outside of the screw 13.

[0023] In this embodiment, a connecting groove is provided on the bottom surface of the groove, a guide rail is installed in the connecting groove, a connecting strip 14 is installed on the bottom surface of the panel 12, the connecting strip 14 is inserted into the guide rail, and the cross-section of the inner cavity of the guide rail and the cross-section of the connecting strip 14 are both arranged in a trapezoidal structure. The panel and the sound insulation cotton can be connected through the guide rail and the connecting strip, so that the movement of the panel can pull the sound insulation cotton below.

[0024] In this embodiment, a plurality of reinforcing plates 11 are installed inside the installation cavity, and channels are provided at the places where the sound insulation cotton 6 is opposite to the reinforcing plates 11. The reinforcing plates 11 are inserted into the corresponding channels. The strength of the middle part of the steel door is increased by the reinforcing plates, and the sound insulation cotton can be positioned up and down by the reinforcing plates, thereby avoiding the vertical movement of the sound insulation cotton and ensuring the stability after the movement.

[0025] In this embodiment, a slide groove 8 is provided on the top surface of the crossbeam 7, and a slider 9 is slidably installed in the slide groove 8. The top surface of the slider 9 is installed on the inner side surface of the L-shaped plate 2. The cross-sections of the slider 9 and the slide groove 8 are both trapezoidal structures. A second screw hole is provided at one end of the slider 9, and a hidden groove is provided on one side of the steel door 1 opposite to the second screw hole. A third screw hole connected to the slide groove 8 is provided on the inner wall surface of the hidden groove. Bolts 3 are threadedly connected in the second screw hole and the third screw hole, and the tail of the bolt 3 is arranged inside the hidden groove.

[0026] In this embodiment, the inner protrusion of the steel door 1 forms an assembly part, and the assembly part is provided with an installation opening 4 for installing a lock. The sound insulation cotton 6 is provided with an assembly groove 10 opposite to the assembly part, and the assembly part is inserted into the assembly groove 10.

[0027] When installing, first use an electric drill to screw out the bolts. After the bolts are no longer fixed, the L-shaped plate can move outward along the slide groove, so that the installation groove is in an open state. At this time, the sound insulation cotton can be inserted into the inside of the steel door, and the assembly groove on the sound insulation cotton can be sleeved on the outside of the assembly part, and the channel is sleeved on the outside of the reinforcement plate. The lower end of the sound insulation cotton protrudes out of the steel door setting. After it is fully installed, the L-shaped plate can be moved in the opposite direction until the L-shaped plate is completely inserted into the steel door, and the moved slider and L-shaped plate are fixed again by bolts;

[0028] On the contrary, when disassembling, just remove the bolts again, and after moving the L-shaped plate outward, the sound insulation cotton can be directly taken out, which greatly facilitates installation and disassembly;

[0029] Among them, the degree of exposure of the sound insulation cotton can be adjusted according to the gap between the steel door and the ground. When adjusting, prepare a wrench. The wrench can be inserted into the installation cavity through the operating port and sleeved on the outside of the rotating ring. By turning the wrench, the screw can be driven to rotate, and the rotating screw can drive the panel to move up and down, thereby synchronously driving the sound insulation cotton at the bottom, so that the sound insulation cotton at the bottom can contact the ground or retract into the inside of the steel door, which has increased adaptability.

[0030] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
