[0007] The fixing device includes a U-shaped component disposed within a C-shaped frame. The U-shaped component has a screw hole, and the C-shaped frame has a mounting hole that mates with the screw hole. A stud is disposed within the screw hole. One end of the stud near the mounting hole has a hexagonal head, and the other end has a plate that can be rotated. The plate has several spikes that can penetrate into the wall.

[0008] As an improvement, the U-shaped part is provided with a screw cylinder that mates with the screw hole, and the stud is located inside the screw cylinder.

[0009] As an improvement, the plate is provided with a rotating groove, and the stud is provided with a circular plate disposed in the rotating groove.

[0010] As an improvement, a decorative cover is installed inside the mounting hole.

[0011] As an improvement, several reinforcing plates are evenly arranged inside the C-shaped frame.

[0012] (III) Beneficial Effects

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1. The fixing device on the door frame facilitates the fixing of the door frame. By rotating the stud, the stud pushes the plate to abut against the door opening, and the door frame can be fixed and installed.

[0015] 2. The spikes on the plate can pierce the wall of the doorway, making the door frame more stable, and thus making the door more stable. Attached Figure Description

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example

[0023] Combined with appendix Figure 1-5 A metal door that is easy to install includes a door frame 1 and a door body 2 hinged within the door frame 1. The door frame 1 is formed by a C-shaped frame 3 with a C-shaped cross-section. Several symmetrically arranged fixing devices 4 are evenly provided on both sides of the C-shaped frame 3.

[0024] The worker places the door frame 1 inside the door opening and uses an electric wrench to operate the fixing device 4 so that the fixing device 4 abuts against the wall of the door opening. Example

[0025] Combined with appendix Figure 4-5 The fixing device 4 includes a U-shaped part 5 disposed within a C-shaped frame 3. The U-shaped part 5 is provided with a screw hole 6. The C-shaped frame 3 is provided with a mounting hole 7 that mates with the screw hole 6. A stud 8 is provided in the screw hole 6. A hexagonal stern head 9 is provided at one end of the stud 8 near the mounting hole 7, and a plate 10 is rotatably provided at the other end. The plate 10 is provided with a plurality of spikes 11 that can penetrate into the wall.

[0026] The plate 10 is provided with a rotating groove 13, and the stud 8 is provided with a circular plate 14 disposed in the rotating groove 13.

[0027] Using an electric wrench on the hexagonal spur head 9, rotate the hexagonal spur head 9. The hexagonal spur head 9 drives the stud 8 and the round plate 14 to rotate. The stud 8 pushes the plate 10 and the spike 11 to abut against the wall of the doorway, so that the spike 11 penetrates into the wall and the door frame 1 is fixed.

[0028] The U-shaped part 5 is provided with a screw cylinder 12 that mates with the screw hole 6, and the stud 8 is provided inside the screw cylinder 12. The screw cylinder 12 can make the stud 8 rotate better.

[0029] A decorative cover 15 is installed inside the mounting hole 7 to cover the mounting hole 7 and make the metal door more beautiful.

[0030] The C-shaped frame 3 is provided with several reinforcing plates 16 evenly distributed inside, making the door frame 1 more robust and stable.

[0031] In the specific implementation of this utility model, the door frame 1 is first placed in the doorway. Then, an electric wrench is used on the hexagonal spur head 9 to turn the hexagonal spur head 9. The hexagonal spur head 9 drives the stud 8 to rotate in the screw hole 6 and the screw cylinder 12. The screw cylinder 12 can strengthen the connection between the stud 8 and the door frame 1, thereby driving the circular plate 14 to rotate. The circular plate 14 pushes the plate body 10 and the spike part 11 to move towards the doorway wall. The spike part 11 pierces into the doorway wall as the stud 8 rotates until the plate body 10 abuts against the doorway wall, thus completing the fixation of the door frame 1. The door body 2 is then installed into the door frame 1 using hinges.

[0032] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions, alterations, deletions of some features, additions of features, or recombinations of features to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the innovative principles of the present invention shall still fall within the scope of the technical solutions of the present invention.
