[0025] Please see Figure 1-6 This utility model provides a technical solution: a steel door that is easy to install, including a mounting frame 1, and a door frame 2 inserted into the inner wall of the mounting frame 1. A steel door body 3 is rotatably connected to the outer wall of the door frame 2 via hinges. The mounting frame 1 serves as the basic support structure for the entire door system and is used to fix it at the door opening. The door frame 2 and the mounting frame 1 are connected by an insertion method. The steel door body 3 is rotatably connected to the door frame 2 via hinges to achieve the normal opening and closing function of the door. A magnetic suction assembly 5 is fixedly connected to the inner wall of the mounting frame 1, and a limit assembly 4 is also fixedly connected to the inner wall of the mounting frame 1. The limit assembly 4 includes a connecting shell 41. A top airbag 43 is fixedly connected to the outer wall of the top of the connecting shell 41, side airbags 42 are fixedly connected to the outer walls of both sides of the connecting shell 41, and a bottom airbag 45 is fixedly connected to the outer wall of the bottom of the connecting shell 41. An air inlet pipe 44 is fixedly connected to the inner wall of the connecting shell 41, and an air plug 46 is inserted into the end of the air inlet pipe 44 away from the connecting shell 41. The outer wall of the connecting shell 41 is fixedly connected to the inner wall of the mounting frame 1, and the inner wall of the top of the mounting frame 1 is fixedly connected to the outer wall of the air inlet pipe 44. Before installing the steel door, the air plug 46 is pulled out from the air inlet pipe 44. At this time, the air inlet pipe 44 is connected to the external air source to create conditions for subsequent airbag inflation.

[0026] The outer wall of the side airbag 42 is fixedly connected to the inner wall of the side of the mounting frame 1. The inner wall of the top of the mounting frame 1 is fixedly connected to the outer wall of the top airbag 43. The inner wall of the bottom of the mounting frame 1 is fixedly connected to the outer wall of the bottom airbag 45. The outer wall of the side airbag 42 is pressed and fixed to the outer wall of the side of the door frame 2. The outer wall of the top of the door frame 2 is pressed and fixed to the outer wall of the top airbag 43. The outer wall of the bottom of the door frame 2 is pressed and fixed to the outer wall of the bottom airbag 45.

[0027] The magnetic attraction component 5 includes corner plates 51, which are arranged in four sets. The outer wall of each set of corner plates 51 is fixedly connected to the inner wall of the mounting frame 1. A top magnetic plate 52 is embedded in the inner wall of the top of the mounting frame 1. A side magnetic plate 53 is slidably connected to the inner wall of the top of the mounting frame 1. An installation block 54 is fixedly connected to the outer wall of the side magnetic plate 53. The outer wall of the installation block 54 is inserted into the inner wall of the mounting frame 1. The outer wall of the corner plate 51 is slidably connected to the outer wall of the door frame 2. The outer wall of the top of the door frame 2 is magnetically attracted to the outer wall of the top magnetic plate 52 and the outer wall of the side magnetic plate 53. Since the door frame 2 is usually made of steel with a certain magnetic attraction, the outer wall of the top of the door frame 2 generates a magnetic attraction force with the outer wall of the top magnetic plate 52 and also with the outer wall of the side magnetic plate 53. According to the principle of magnetism, opposite magnetic poles attract each other.

[0028] This easy-to-install steel door mainly consists of an installation frame 1, a door frame 2, a steel door body 3, a limiting component 4, and a magnetic suction component 5. The installation frame 1 serves as the basic support structure for the entire door system and is used to fix it at the door opening. The door frame 2 is connected to the installation frame 1 by a plug-in connection. The steel door body 3 is rotatably connected to the door frame 2 through hinges to realize the normal opening and closing function of the door. The limiting component 4 and the magnetic suction component 5 work together to ensure that the door frame 2 is positioned and stably fixed within the installation frame 1.

[0029] The limiting component 4 includes a connecting shell 41, a top airbag 43, a side airbag 42, a bottom airbag 45, and an air inlet pipe 44. The connecting shell 41 is fixed to the inner wall of the mounting frame 1. One end of the air inlet pipe 44 is connected to the inside of the connecting shell 41, and the other end is connected to an air plug 46. The air inlet pipe 44 is fixed to the inner wall of the top of the mounting frame 1. The top airbag 43 is fixed to the outer wall of the top of the connecting shell 41. The side airbags 42 are fixed to the outer walls of both sides of the connecting shell 41. The bottom airbag 45 is fixed to the outer wall of the bottom of the connecting shell 41.

[0030] Before installing the steel door, remove the air plug 46 from the air inlet pipe 44. At this time, connect the air inlet pipe 44 to the external air source to create conditions for the subsequent inflation of the airbag. This process utilizes the principle of atmospheric pressure. The external air source is higher than the internal pressure of the airbag, and air will naturally flow into the connecting shell 41 through the air inlet pipe 44.

[0031] After air enters the connecting shell 41, since the connecting shell 41 is interconnected with the top airbag 43, side airbag 42 and bottom airbag 45, the air will quickly flow into each airbag. According to the principle of gas diffusion, gas always diffuses from the area of ​​high pressure to the area of ​​low pressure, causing the internal pressure of the airbag to gradually increase and the airbag to begin to inflate.

[0032] When the door frame 2 is inserted into the mounting frame 1, the inflated top airbag 43 is pressed tightly against the top outer wall of the door frame 2, the side airbag 42 is pressed against the side outer wall of the door frame 2, and the bottom airbag 45 is pressed against the bottom outer wall of the door frame 2. According to the principle of action and reaction, the airbags apply pressure to the door frame 2, and at the same time, the door frame 2 also generates a reaction force on the airbags, so that the door frame 2 is restricted in the up-down, left-right, and front-back directions within the mounting frame 1, thus achieving initial positioning.

[0033] After installation, the air plug 46 is reinserted into the air intake pipe 44 to prevent air from continuing to flow into or out of the airbag. At this time, the internal pressure of the airbag remains stable, continuously applying pressure to the door frame 2 to ensure that the door frame 2 is stable in the mounting frame 1.

[0034] The magnetic suction assembly 5 consists of four sets of corner plates 51, a top magnetic plate 52, side magnetic plates 53 and a mounting block 54. The corner plates 51 are fixed to the inner wall of the mounting frame 1, the top magnetic plate 52 is embedded in the inner wall of the top of the mounting frame 1, the side magnetic plate 53 is slidably connected to the inner wall of the top of the mounting frame 1, and the outer wall of the side magnetic plate 53 is inserted into the inner wall of the mounting frame 1 through the mounting block 54.

[0035] During the process of inserting the door frame 2 into the installation frame 1, the outer wall of the corner plate 51 slides in contact with the outer wall of the door frame 2. The corner plate 51 plays a guiding and auxiliary support role. According to the principle of sliding friction, the corner plate 51 guides the door frame 2 into the installation frame 1, and at the same time restricts the offset of the door frame 2 to a certain extent, ensuring that the door frame 2 can smoothly reach the predetermined position.

[0036] After the door frame 2 is initially positioned by the limiting component 4, since the door frame 2 is usually made of steel with a certain magnetic adsorption, the outer wall of the top of the door frame 2 generates a magnetic adsorption force with the outer wall of the top magnetic plate 52, and also generates a magnetic adsorption force with the outer wall of the side magnetic plate 53. According to the principle of magnetism, opposite magnetic poles attract each other. This magnetic adsorption force further strengthens the fixing effect of the door frame 2 in the installation frame 1, ensuring that the door frame 2 will not easily move.

[0037] When installing the side magnetic plate 53, the operator pushes the mounting block 54 to make the side magnetic plate 53 slide on the inner wall of the top of the mounting frame 1. By adjusting the position of the side magnetic plate 53, it is locked in the mounting frame 1, thereby giving full play to the magnetic adsorption effect and further enhancing the fixed stability of the door frame 2.

[0038] First, fix the mounting frame 1 in the doorway position, ensuring that the horizontal and vertical alignment of the mounting frame 1 meets the installation requirements. This is the foundation of the entire installation process and provides stable support for the installation of subsequent components.

[0039] Pull out the air plug 46 on the air inlet pipe 44 to allow external air to flow into the connecting shell 41, thereby inflating the top airbag 43, side airbag 42, and bottom airbag 45 to prepare for the positioning of the door frame 2. Insert the door frame 2 with the steel door body 3 into the mounting frame 1, and use the inflated airbags to initially position the door frame 2, restricting its movement in all directions. Push the mounting block 54 to adjust the position of the side magnetic plate 53 so that it fits tightly against the top outer wall of the door frame 2. Use the magnetic attraction of the top magnetic plate 52 and the side magnetic plate 53 to further fix the position of the door frame 2 in the mounting frame 1. Reinsert the air plug 46 into the air inlet pipe 44 to maintain stable pressure inside the airbag and continuously apply pressure to the door frame 2 to ensure stable installation of the door frame 2. After installation, conduct a comprehensive inspection of the steel door to ensure that the door frame 2 is firmly installed and that the steel door body 3 opens and closes smoothly. If necessary, make appropriate adjustments to ensure normal use of the door.
