[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 - 7 , a modular spliced steel door with quick installation and disassembly, including a door panel 1 and a door frame 2. The door panel 1 is arranged inside the door frame 2, and a frame border positioning mechanism is provided inside the door frame 2. The frame border positioning mechanism includes two side supplementary plates 319 that are slidably connected to the inner sides of both sides of the door frame 2. A top supplementary plate 303 is slidably connected to the top of the door frame 2, so that the top supplementary plate 303 and the two side supplementary plates 319 respectively abut against the top and both sides of the door opening, and the door frame 2 can be fixed in the door opening.

[0037] Among them, second sliding grooves 315 are formed in the front surfaces of the left side, right side, and upper end of the door frame 2. A moving plate 312 is slidably connected to the inside of each of the three second sliding grooves 315. The three moving plates 312 are respectively fixedly connected to the top supplementary plate 303 and the two side supplementary plates 319. Support plates 313 are fixedly connected to the front surfaces of the left side, right side, and upper end of the door frame 2. A frame positioning screw 311 is rotatably connected to the surface of the support plate 313. The frame positioning screw 311 is threadedly inserted into the inside of the moving plate 312. The corresponding three moving plates 312 can be driven to move leftward, rightward, and upward respectively by the three frame positioning screws 311. A second hexagonal head 314 is fixedly connected to one end of the frame positioning screw 311 away from the support plate 313.

[0038] Among them, side filling plates 301 are inserted into the front and rear surfaces of the side supplementary plate 319. A corner supplementary plate 302 is slidably inserted into the top end of the side filling plate 301. The top parts of the two corner supplementary plates 302 are respectively fixedly connected to a top connecting plate 309 and a top connecting clamping plate 310. A first sliding groove 308 is formed in the surface of the top connecting clamping plate 310. A connecting column 307 is fixedly connected to the upper surface of the top connecting plate 309. The connecting column 307 is slidably connected to the inside of the first sliding groove 308. When one of the corner supplementary plates 302 moves, the other corner supplementary plate 302 can be driven to move synchronously, reducing the installation steps and not affecting the operation of other steps. A support block 305 is fixedly connected to the upper end of the front side filling plate 301. A corner positioning screw 304 is rotatably connected to the inside of the support block 305. The top end of the corner positioning screw 304 is threadedly inserted into the bottom of the corner supplementary plate 302. The corner supplementary plate 302 can be made to abut against the top of the door opening by the corner positioning screw 304. A first hexagonal head 306 is fixedly connected to the bottom end of the corner positioning screw 304. Turning the first hexagonal head 306 with a wrench can make the corner positioning screw 304 rotate.

[0039] Among them, top side supplementary plates 316 are slidably connected to both ends of the top supplementary plate 303. The corners can be filled by the top side supplementary plates 316 and the corner supplementary plates 302, improving the airtightness after the installation of the door frame 2. Top side positioning screws 317 are threadedly inserted into both ends of the top supplementary plate 303. One end of each of the two top side positioning screws 317 away from each other is rotatably connected to one end of the two top side supplementary plates 316 close to each other. The top side supplementary plates 316 can be made to abut against the sides of the corner supplementary plates 302 by the top side positioning screws 317. A third hexagonal head 318 is fixedly connected to one end of each of the two top side positioning screws 317 away from each other. Turning the third hexagonal head 318 with a wrench can make the top side positioning screws 317 rotate.

[0040] By adopting the above technical solution, when installing the steel door, the door frame 2 is set in the door opening to be installed, and the door panel 1 is set in the door frame 2. Then, use a wrench to rotate the second hexagon head 314, and the three border positioning screws 311 can drive the corresponding three moving plates 312 to move towards the left, right, and upper ends respectively, pushing the top supplementary plate 303 and the two side supplementary plates 319 out of the door frame 2 respectively, so that the top supplementary plate 303 and the two side supplementary plates 319 abut against the top and both sides of the door opening respectively, and thus the door frame 2 can be fixed in the door opening.

[0041] After the fixing of the door frame 2 is completed, take out the side filling plate 301 from the side supplementary plate 319, and then use a wrench to rotate the first hexagon head 306. The corner positioning screw 304 can drive the corner supplementary plate 302 to move upward, so that the corner supplementary plate 302 abuts against the top of the door opening. Then, use a wrench to rotate the third hexagon head 318, and the top side positioning screw 317 can drive the top side supplementary plate 316 to extend out of the top supplementary plate 303, so that the top side supplementary plate 316 abuts against the side of the corner supplementary plate 302. Thus, the corner that cannot be blocked at the adjacent ends of the side supplementary plate 319 and the corner supplementary plate 302 can be filled, greatly improving the airtightness after the installation of the door frame 2.

[0042] As Figure 1 、 Figure 8 、 Figure 9 and Figure 10 shown, a disassembly and assembly mechanism is provided on the surface of the door panel 1. The disassembly and assembly mechanism includes a sliding rod 405 fixedly connected to the back surface of the door panel 1. A second hinge 407 is arranged on the surface of the sliding rod 405. The opening and closing of the door panel 1 during use is realized through the second hinge 407. The second hinge 407 is composed of two blades. The two blades of the second hinge 407 are respectively fixedly connected with a sliding plate 408 and a hook plate 409. The sliding plate 408 is slidably connected to the surface of the sliding rod 405. A clamping plate 406 is fixedly connected to the back surface of one side of the door frame 2, so that the hook plate 409 can be hooked on the clamping plate 406 to complete the quick installation of the door panel 1.

[0043] Among them, the number of the door panels 1 is two. The two door panels 1 are rotatably connected by a first hinge 401. The two door panels 1 can be folded through the first hinge 401, which is convenient for handling and transportation. At the back of one end of the two door panels 1 close to each other, an arc-shaped insertion plate 402 and an arc-shaped accommodating plate 403 are respectively fixedly connected. The arc-shaped insertion plate 402 is inserted into the arc-shaped accommodating plate 403. A rubber clamping ring 404 is fixedly connected to the upper end of the arc-shaped accommodating plate 403. The rubber clamping ring 404 can provide resistance when folding the door panel 1, reduce the speed and force when folding the door panel 1, and improve the safety of operation. The rubber clamping ring 404 is sleeved on the surface of the arc-shaped insertion plate 402.

[0044] By adopting the above technical solution, after the installation of the door frame 2 is completed, the two door panels 1 are unfolded and arranged in the door frame 2. Then, the sliding plate 408 is moved downward along the path of the sliding rod 405, so that the hook plate 409 moves into the clamping plate 406, and the hook plate 409 can be hooked on the clamping plate 406 to complete the quick installation of the door panel 1. The opening and closing of the door panel 1 during use are realized through the second hinge 407.

[0045] When disassembling the door panel 1, moving the sliding plate 408 upward can make the hook plate 409 disengage from the clamping plate 406, and the door panel 1 can be disassembled from the door frame 2. Then, the rotation of the two door panels 1 is realized through the first hinge 401, and the two door panels 1 can be folded, which is convenient for handling and transportation. During the folding process of the door panel 1, since the door panel 1 is made of steel and is relatively heavy as a whole, it is easy to drop the hand directly during folding, resulting in the door panel 1 clamping the staff's hand or other objects. Therefore, the rubber clamping ring 404 can hold the arc-shaped insertion plate 402. Through the friction between the rubber clamping ring 404 and the arc-shaped insertion plate 402, resistance can be provided when folding the door panel 1, reduce the speed and force when folding the door panel 1, and improve the safety of operation.

[0046] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
