[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The following is combined with Figure 1-7 This application is described in further detail.

[0028] The present invention provides a soundproof door capable of improving sound insulation, comprising a door frame 1 mounted on a floor 4, and a door panel 2 rotatably mounted on the door frame 1. The door panel 2 is rotatably connected to the upper end of the door frame 1 via a rotating shaft 9. The right end of the door panel 2 comprises a rotating portion 21 for receiving the rotating shaft 9. The rotating portion 21 is in the shape of an outwardly convex arc to prevent the door panel 2 from being pressed against the right end of the door frame 1 when rotating about the rotating shaft 9. A first sealing plate 3 is provided at the lower end of the outer surface of the door panel 2. A groove 41 is defined in the floor 4, in which an elastic member 5 is vertically fixed. A second sealing plate 6 is fixedly mounted on the elastic member 5. Specifically, the elastic member 5 is connected to the second sealing plate 6 via a guide block 20. The guide block 20 serves as a guide to facilitate stable upward and downward movement of the second sealing plate 6. When the door panel 2 is closed (in this article, "door panel 2 is closed" refers to the state when the door panel 2 is completely closed), the first sealing plate 3 and the second sealing plate 6 come into contact. The lower end surface of the door frame 1 is provided with a clearance groove 11. When the door panel 2 is opened, at least a portion of the first sealing plate 3 is accommodated in the clearance groove 11. When the door panel 2 is opened, a portion of the first sealing plate 3 is accommodated in the clearance groove 11, thereby preventing the door frame 1 from pressing against the first sealing plate 3 and hindering the opening of the door panel 2. This device improves the sound insulation effect by providing contact between the first sealing plate 3 and the second sealing plate 6. At the same time, there is no need to worry about the sealing plate rubbing against the ground 4, causing damage to the sealing plate and affecting the sound insulation effect.

[0029] Furthermore, the cross-section of the first sealing plate 3 is an inverted right triangle, and the cross-section of the second sealing plate 6 is a trapezoid, preferably an isosceles trapezoid. The second sealing plate 6, which has an isosceles trapezoidal cross-section, has two inclined surfaces. The inclined surface of the first sealing plate 3 contacts one of the inclined surfaces 61 of the second sealing plate 6 in the following two situations: when the door panel 2 is closed, the inclined surface of the first sealing plate 3 is in close contact with one of the inclined surfaces 61 of the second sealing plate 6; when the door panel 2 is opening, the inclined surface of the first sealing plate 3 slides along one of the inclined surfaces 61 of the second sealing plate 6 and presses the second sealing plate 6 downward, facilitating the opening of the door panel 2.

[0030] Furthermore, a sealing gasket is provided on the inclined surface of the first sealing plate 3. When the door panel 2 is closed, the first sealing plate 3 contacts one of the inclined surfaces 61 of the second sealing plate 6 via the sealing gasket to achieve further sealing.

[0031] In one embodiment, a third sealing plate 7 is provided at the lower end of the inner surface of the door panel 2. The cross-section of the third sealing plate 7 is preferably an inverted right triangle, so that the third sealing plate 7 can be well adapted to the other inclined surface 62 of the second sealing plate 6. The contact between the inclined surface of the third sealing plate 7 and the other inclined surface 62 of the second sealing plate 6 is as follows: when the door panel 2 is closed, the inclined surface of the third sealing plate 7 slides along the other inclined surface 62 of the second sealing plate 6 and presses the second sealing plate 6 downward; when the door panel 2 is completely closed, the second sealing plate 6 bounces upward under the action of the rebound force of the elastic member 5. At this time, the inclined surface of the first sealing plate 3 is in close contact with one of the inclined surfaces 61 of the second sealing plate 6 to achieve sealing.

[0032] Preferably, the first sealing plate 3, the second sealing plate 6, the third sealing plate 7 and the sealing gasket in the present invention are all made of hard rubber, which has good wear resistance and elasticity and can improve the overall service life of the present invention.

[0033] In another embodiment, a magnetic strip 8 is adsorbed on the upper end of the door panel 2. When the door panel 2 is closed, the magnetic strip 8 will be adsorbed on the upper end of the door frame 1 to seal the upper end gap between the door panel 2 and the door frame 1, thereby achieving better sealing and sound insulation effects. Similarly, the left end gap between the door panel 2 and the door frame 1 is sealed and soundproofed in the same manner as the upper end gap. A sound insulation felt 10 is fixedly connected to the right end of the door panel 2 and the right end of the door frame 1. The sound insulation felt 10 is used to seal the right end gap between the door panel 2 and the door frame 1. Because the sound insulation felt 10 not only has sound insulation and sealing effects, but is also made of flexible material, it prevents the sound insulation felt 10 from being broken when the door panel 2 rotates.

[0034] The following is the overall working principle of the door panel 2 of the present invention when opening and closing:

[0035] When the door panel 2 is in the process of opening, the inclined surface of the first sealing plate 3 will slide along one of the inclined surfaces 61 of the second sealing plate 6 and squeeze the second sealing plate 6 downward; when the door panel 2 is in the process of closing, the inclined surface of the third sealing plate 7 will slide along the other inclined surface 62 of the second sealing plate 6 and squeeze the second sealing plate 6 downward; when the door panel 2 is closed, the second sealing plate 6 will bounce upward under the action of the rebound force of the elastic member 5. At this time, the inclined surface of the first sealing plate 3 is in close contact with one of the inclined surfaces 61 of the second sealing plate 6, so as to achieve the effect of improving the sealing and sound insulation. At the same time, there is no need to worry about the sealing plate rubbing against the ground 4, causing damage to the sealing plate and affecting the sound insulation effect.
