Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples are given below.

[0019] like Figures 1 to 5 As shown in the embodiment of this utility model, a steel fire door with an extremely narrow frame structure includes a frame body 1. A side block 5 is fixedly connected to the right side of the frame body 1, and a connecting block 7 is rotatably connected to the outside of the side block 5. A door body 3 is fixedly connected to the right side of the connecting block 7. An installation unit 6 is provided on the inner side of the frame body 1, and a folded edge 2 is fixedly connected to the front side of the frame body 1. The installation unit 6 includes multiple branch plates 64, which are fixedly connected to the inner side of the frame body 1. A sliding groove 65 is provided on the outer side of the branch plate 64, and the inner side of the sliding groove 65 slides. A slider 66 is connected, and a connecting plate 68 is fixedly connected to the outside of the slider 66. Two insert rods 69 are fixedly connected to the left side of the connecting plate 68, and a moving block 610 is fixedly connected to the outside of the connecting plate 68. A screw 62 is provided on the right side of the moving block 610. When installing the frame body 1, first rotate the screw 62. The screw 62 drives the moving block 610 to move, the moving block 610 drives the connecting plate 68 to move, and the connecting plate 68 drives the insert rods 69 to move, so that the insert rods 69 are inserted into the positioning holes that have been opened in advance in the wall, which facilitates the initial positioning.

[0020] The right end of the screw 62 passes through the right side of the frame body 1 and is threadedly connected to the frame body 1. A circular groove 61 is provided on the right side of the frame body 1, and a cross groove 63 is provided on the right end of the screw 62. The screw 62 is rotatably connected to the moving block 610. A through hole 4 is provided on the left side of the frame body 1. The insertion rod 69 is adapted to the through hole 4 and is slidably connected to the frame body 1. During installation, the screw 62 is rotated by rotating through the cross groove 63, and the right end of the screw 62 is located inside the circular groove 61 through the circular groove 61, so as to avoid the screw 62 affecting the rotation of the door body 3.

[0021] A rectangular hole 611 is provided on the left side of the frame body 1. A positioning box 612 is fixedly connected to the left side of the frame body 1. An extension hole 613 is provided on both the upper and lower sides of the positioning box 612. An extension plate 614 is provided on the inner side of the extension hole 613 on both the upper and lower sides. A moving rod 615 is fixedly connected to the outer side of the extension plate 614. A rotating groove 617 is provided at the outer end of the moving rod 615. An inclined plate 618 is rotatably connected to the inner side of the rotating groove 617 on both the upper and lower sides. A rotating block 619 is rotatably connected to the outer side of the inclined plate 618. A push plate 620 is fixedly connected to the right side of the rotating block 619. A push rod 622 is fixedly connected between the push plate 620 and the moving block 610. The two inclined plates 618 are arranged symmetrically. A sliding rod 621 is fixedly connected to the inside of the frame body 1. The sliding rod 621 is slidably connected to the push plate 620. A fixing plate 616 is fixedly connected to the inside of the positioning box 612. The moving rod 615 is slidably connected to the fixing plate 616.

[0022] When initially positioning the wall, a positioning hole adapted to the positioning box 612 is dug in the wall. Two holes adapted to the extension plate 614 are dug in the inner wall of the positioning hole. At this time, the moving block 610 drives the push rod 622 to move, the push rod 622 drives the push plate 620 to move, the push plate 620 drives the inclined plate 618 to rotate, the inclined plate 618 drives the moving rod 615 to move, and the moving rod 615 drives the extension plate 614 to move. The extension plates 614 on the upper and lower sides are adapted to the dug holes, which facilitates the quick positioning and installation of the frame body 1 and increases the stability of the installation.

[0023] A reinforcing plate 67 is fixedly connected to the outside of the branch plate 64. The reinforcing plate 67 has an X-shaped structure and is made of aluminum alloy. By setting the reinforcing plate 67, the internal stability of the frame body 1 is increased.

[0024] During operation, when in use, holes are first made on the inner side of the wall to fit the insertion rod 69, positioning box 612, and extension plate 614. Then, the insertion rod 69 on the frame body 1 is inserted into the hole in the wall. Then, the screw 62 is rotated, which drives the moving block 610 to move. The moving block 610 drives the connecting plate 68 to move, and the connecting plate 68 drives the insertion rod 69 to move, so that the insertion rod 69 is inserted deeper into the hole. At the same time, the moving block 610 drives the push rod 622 to move. Under the action of the push plate 620, the inclined plate 618, and the moving rod 615, the extension plate 614 is extended, which increases the stability of the frame body 1 installation. The operation is simple.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
