A fixed seat 2 is installed at the left end of the front end face of the main body 1 by screws. A handle 3 is rotatably installed at the front end of the fixed seat 2. A core plate 4 is disposed at the inner bottom of the main body 1.

[0026] An auxiliary component 5 is provided on the front end face inside the main body 1, and a noise reduction component 6 is provided on the rear end face inside the main body 1. The auxiliary component 5 includes a grid steel plate 51 provided on the front end face inside the main body 1 to enhance the overall strength of the door panel. A perlite fireproof board 52 is fixed to the rear end face of the grid steel plate 51 by screws. A fiberglass layer 53 is fixedly connected to the rear end face of the perlite fireproof board 52. The perlite fireproof board 52 has good fire prevention, heat preservation, anti-static and other effects.

[0027] The heat insulation layer 54 is adhesively installed on the rear end face of the fiberglass layer 53. The core board 4 is adhesively fixed to the rear end of the heat insulation layer 54. The rear end of the core board 4 is fixed to the reinforcing plate installed on the rear end face inside the main body 1 by screws. Antirust primer layers are coated on the outer sides of the grid steel plate 51 and the reinforcing plate 55 to prevent the grid steel plate 51 and the reinforcing plate 55 from rusting. An acrylic intumescent fireproof coating is applied to the front end face of the perlite fireproof board 52 to delay combustion with the help of the acrylic intumescent fireproof coating.

[0028] The working principle of the door panel structure of a steel art door based on Embodiment 1 is:

[0029] The overall strength of the door panel is enhanced by the provided grid steel plate 51 and the reinforcing plate 55. The flame can be effectively retarded by utilizing the material properties of the perlite fireproof board 52 and the fiberglass layer 53, and the combustion is delayed with the help of the acrylic intumescent fireproof coating. Moreover, the heat inside the house can be blocked by the heat insulation layer 54 and the perlite fireproof board 52 to facilitate heat insulation and preservation inside the house. In this way, the overall strength of the door panel can be effectively enhanced by the grid steel plate 51 and the reinforcing plate 55, and the fire retardant and heat preservation effects of the door panel are improved with the help of the perlite fireproof board 52 and the fiberglass layer 53.

[0030] Embodiment Two:

[0031] Please refer to Figures 1 to 5 , for the door panel structure of a steel art door of the present utility model. Compared with Embodiment 1, this embodiment further includes: The noise reduction component 6 includes a first sound absorption board 61 provided on the rear end face of the core board 4, and a groove is opened at the front end of the first sound absorption board 61 for sliding connection with the reinforcing plate 55. The first sound absorption board 61 provides stability for the installation of the sound absorption cotton 62. The rear end face of the first sound absorption board 61 is adhesively connected to the sound absorption cotton 62. The sound absorption cotton 62 is adhesively installed with a sound insulation pad 63, and energy absorption and noise reduction are carried out by contacting the noise through the sound insulation pad 63.

[0032] The front end face of the first sound-absorbing panel 61 is evenly provided with sound-absorbing holes 64. The rear end face inside the main body 1 is fixedly installed with a second sound-absorbing panel 65, and the front end of the second sound-absorbing panel 65 is adhesively connected to the sound insulation pad 63. Reflecting rods 66 are welded and fixed to the sound-absorbing holes 64 at the front end of the first sound-absorbing panel 61. The reflecting rods 66 are in contact with the front end face of the sound-absorbing cotton 62. Noise undergoes diffuse reflection with the spiral inclined surface on the outer side of the reflecting rod 66, thereby changing the propagation direction of the noise. The thickness of the sound-absorbing cotton 62 is twenty-five millimeters, providing partial specification values of the sound-absorbing cotton 62.

[0033] In this embodiment:

[0034] When the noise contacts the main body 1, the noise enters the sound-absorbing holes 64 on the first sound-absorbing panel 61. When inside the sound-absorbing holes 64, the noise contacts the reflecting rods 66. At this time, the noise undergoes diffuse reflection with the spiral inclined surface on the outer side of the reflecting rods 66, thereby changing the propagation direction of the noise, and effectively reducing the internal energy of the noise through collision for noise reduction. The provided sound-absorbing cotton 62 absorbs and isolates the noise, and contacts the noise through the sound insulation pad 63 for energy absorption and noise reduction. This facilitates the noise to contact the reflecting rods 66 to undergo diffuse reflection and change the propagation direction, thereby reducing the internal energy of the noise through collision, and with the help of the sound-absorbing cotton 62 and the sound insulation pad 63, energy absorption and noise reduction are carried out on the noise, thus effectively improving the noise reduction effect of the door panel.

[0035] Through improvement, the present utility model provides a door panel structure for a steel art door. An auxiliary component 5 is arranged on the front end face inside the main body 1, and the inside of the door panel is supported by the grid steel plate 51. In this way, through the grid steel plate 51 and the reinforcing plate 55, the overall strength of the door panel can be effectively enhanced, and with the help of the perlite fireproof board 52 and the fiberglass layer 53, the fireproof, flame-retardant and heat preservation effects of the door panel are improved; a noise reduction component 6 is arranged on the rear end face inside the main body 1, and the sound insulation pad 63 is used for energy absorption and noise reduction of the noise. This facilitates the noise to contact the reflecting rods 66 to undergo diffuse reflection and change the propagation direction, thereby reducing the internal energy of the noise through collision, and with the help of the sound-absorbing cotton 62 and the sound insulation pad 63, energy absorption and noise reduction are carried out on the noise, thus effectively improving the noise reduction effect of the door panel.
