[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides a fireproof door that is easy to install, including a door body 1 and a door frame 2. The door body 1 is rotatably installed inside the door frame 2 through a hinge. The top of the door frame 2 is slidably connected with an installation component 3. The installation component 3 includes a first slider 31, a second slider 32, a double-headed rotating rod 33 and a docking frame 34, wherein two double-headed rotating rods 33 are rotatably installed on both sides of the first slider 31, and the other two double-headed rotating rods 33 are rotatably installed on both sides of the second slider 32. One ends of the four double-headed rotating rods 33 are rotatably connected to the bottom of the docking frame 34, a support plate 5 is fixedly connected to the inner wall of the door frame 2, the first slider 31 and the second slider 32 are both slidably connected to the inside of the support plate 5, a positioning hole 39 is provided inside the docking frame 34, a sliding groove 4 is provided at the intersection of the support plate 5 and the first slider 31 and the second slider 32, and a positioning groove 6 is provided on the lower surface of the support plate 5.

[0026] The specific settings and functions of this embodiment are described in detail below. The door body 1 is installed inside the door frame 2 through a hinge, and the door frame 2 is connected to the wall through the installation component 3. The installation component 3 and the door body 1 are separated by a support plate 5. When the installation component 3 is connected to the wall, a groove whose shape matches the shape of the docking frame 34 is first opened on the wall in advance, and the first slider 31 or the second slider 32 is pushed at the same time inside the slide groove 4. When the first slider 31 and the second slider 32 move, the docking frame 34 is pushed upward by the double-headed rotating rod 33, so that the top of the docking frame 34 is docked to the wall;

[0027] A positioning hole 39 is reserved inside the docking frame 34. After lifting the docking frame 34, a wall nail is driven into the positioning hole 39. The nail passes through the positioning hole 39 and enters the wall to complete the connection between the docking frame 34 and the wall. After determining the position of the docking frame 34, filler is injected into the inside of the slide groove 4 to fill the gap of the slide groove 4. The filler can be glass glue or expansion glue, and it can also fill the gap between the door frame 2 and the wall to improve the stability of the door frame 2.

[0028] Embodiment 2

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, the bottom of the first slider 31 and the bottom of the second slider 32 are fixedly connected to a limiting plate 35, the limiting plate 35 is located inside the positioning groove 6, and threaded holes 36 are provided at the four corners of the limiting plate 35. A blocking plate 37 is fixedly installed on the inner wall of the docking frame 34, and one side of the blocking plate 37 is overlapped on one side of the door frame 2. A docking slot 38 is provided between the blocking plate 37 and the docking frame 34, the door frame 2 is located inside the docking slot 38, and the door body 1 is located below the support plate 5.

The limiting plate 35 is located inside the positioning groove 6 to prevent the first slider 31 and the second slider 32 from being misaligned. Expansion screws can be nailed into the threaded holes 36 to fix the first slider 31 and the second slider 32 on the support plate 5, thereby ensuring the stability of the first slider 31 and the second slider 32.

[0031] The docking frame 34 is connected to the top of the door frame 2 through the blocking plate 37 and the docking slot 38, which can ensure the stability of the docking frame 34. The door body 1 is located below the support plate 5, and the limit plate 35 is located in the positioning groove 6, which will not affect the rotation of the door body 1.

[0032] The use method and working principle of the device: when connecting the installation component 3 to the wall, first open a groove on the wall in advance, the shape of which matches the shape of the docking frame 34, then align the docking frame 34 with the groove, and at the same time push the first slider 31 or the second slider 32, lift the docking frame 34 through the double-headed rotating rod 33, so that the top of the docking frame 34 is docked into the wall, and finally drive the wall nail into the inside of the positioning hole 39;

[0033] After determining the position of the docking frame 34, expansion screws are driven into the threaded holes 36 of the limit plate 35 to fix the first slider 31 and the second slider 32 to the support plate 5, and fillers made of glass glue and expansion glue are injected into the interior of the slide groove 4 to fill the gap of the slide groove 4. In this way, the installation component 3 is fixed. At the same time, the limit plate 35 is located in the positioning groove 6 and will not affect the rotation of the door body 1.
