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

[0021] Example:

[0022] like Figures 1 to 5 As shown, this utility model embodiment provides a quick-installation door frame, including a door frame body 1. A slot 101 is provided in the middle of the door frame body 1. Several fixing steel plates 2 are installed in the slot 101. A hinge 205 is installed above the fixing steel plates 2. A decorative cover 3 is installed at the opening of the slot 101 of the door frame body 1.

[0023] This embodiment of the utility model features a through-groove 101 machined in the middle of the door frame body 1. A matching fixing steel plate 2 is installed in the groove 101, with the fixing steel plate 2 inserted in sections within the groove 101. Hinges 205 are installed on the upper surface of the fixing steel plate 2 using bolts 204. The installation position of the hinges 205 is determined according to the door specifications and opening method. A decorative cover 3 is aligned and installed at the opening of the groove 101 in the door frame body 1, covering the opening of the groove 101 and concealing the internal fixing steel plate 2. The fixing steel plate 2 provides a stable installation base for the hinges 205, enhancing the reliability of the connection between the door frame and the door. The decorative cover 3 not only protects the installed components in the groove 101, preventing dust and debris from entering, but also makes the door frame look cleaner and more beautiful, improving the overall decorative effect. At the same time, the modular design of each component makes the installation process simpler and faster, improving the installation efficiency of the door frame.

[0024] In one feasible implementation scheme, such as Figure 1 As shown, the door frame body 1 is made of aluminum alloy profile. By using aluminum alloy profile extrusion molding process to manufacture the door frame body 1, compared with traditional steel door frames, the overall weight of the door frame is reduced, making it easier to transport and install. At the same time, it reduces the load on the wall. The good corrosion resistance of aluminum alloy allows it to adapt to different usage environments, reducing later maintenance costs and extending the service life of the door frame.

[0025] In one feasible implementation scheme, such as Figure 2 and Figure 4 As shown, bolt holes 201 are provided at both ends of the fixed steel plate 2. The fixed steel plate 2 is fixed to the wall by passing through the bolt holes 201 and the door frame body 1 with self-tapping bolts 202. By machining bolt holes 201 at both ends of the fixed steel plate 2, when installing the door frame, first place the door frame body 1 in the predetermined installation position, aligning the bolt holes 201 on the fixed steel plate 2 with the preset holes on the wall. Then, use self-tapping bolts 202 to pass through the bolt holes 201 and the door frame body 1 to fix the fixed steel plate 2 to the wall. The threads of the self-tapping bolts 202 can automatically tap when screwed into the wall, eliminating the need to pre-machine threaded holes on the wall, simplifying the installation steps. This connection method features convenient installation and firm fixation. The bolt holes 201 at both ends of the fixed steel plate 2 can evenly distribute the fixing force, forming a stable connection between the door frame body 1 and the wall, effectively improving the overall stability and impact resistance of the door frame. At the same time, the use of self-tapping bolts 202 avoids the significant damage to the wall caused by traditional fixing methods such as expansion bolts 204. It is suitable for various types of wall materials, such as brick walls and concrete walls, expanding the applicability of the door frame.

[0026] In one feasible implementation scheme, such as Figure 3 and Figure 4 As shown, several bolt holes 203 are provided in the middle of the fixed steel plate 2. These bolt holes 203 are used to fix the hinge 205 with bolts 204. By machining several bolt holes 203 in the middle of the fixed steel plate 2 according to the installation dimensions and quantity of the hinge 205, and matching the arrangement and spacing of the bolt holes 203 with the bolt holes 204 on the hinge 205, it is ensured that the hinge 205 can be accurately installed on the fixed steel plate 2. This provides multiple fixing points for the hinge 205, allowing it to bear force evenly, ensuring the door remains stable during opening and closing, reducing wear on the hinge 205 and door wobbling. When installing the hinge 205, Hinge 205 is placed at a predetermined position on fixed steel plate 2, aligning the bolt 204 hole on hinge 205 with the bolt hole 203 on fixed steel plate 2. Then, bolts 204 are passed through bolt hole 203 to fix hinge 205 to fixed steel plate 2, which improves the connection strength and stability between hinge 205 and fixed steel plate 2, ensuring the performance and service life of the door. At the same time, the standardized bolt hole 203 design facilitates the installation and replacement of hinge 205, improving the maintenance convenience of the door frame.

[0027] In one feasible implementation scheme, such as Figure 5 As shown, the decorative cover 3 is provided with a snap-fit ​​structure 301, and the door frame body 1 is provided with a protrusion 102 that cooperates with the snap-fit ​​structure 301 of the decorative cover 3. By providing a protruding snap-fit ​​structure 301 on the decorative cover 3, the shape and size of the snap-fit ​​structure 301 match the protrusion 102 on the door frame body 1. When installing the decorative cover 3, align the snap-fit ​​structure 301 on the decorative cover 3 with the protrusion 102 on the door frame body 1, press or push the decorative cover 3 to make the snap-fit ​​structure 301 engage with the protrusion 102, thus achieving a fixed connection between the decorative cover 3 and the door frame body 1. The engagement of the snap-fit ​​structure 301 and the protrusion 102 enables the quick installation and removal of the decorative cover 3 without the need for additional tools and connectors, improving installation efficiency. This connection method allows the decorative cover 3 to fit tightly against the opening of the slot 101 of the door frame body 1, effectively concealing the internal installation structure and maintaining the neatness and aesthetics of the door frame. At the same time, the snap-fit ​​structure 301 has a certain degree of elasticity and stability, ensuring that the decorative cover 3 will not easily fall off during use. Furthermore, when it is necessary to maintain or repair the components inside the slot 101, the decorative cover 3 can be easily disassembled, improving the ease of use and maintainability of the door frame.

[0028] In one feasible implementation scheme, such as Figure 5As shown, the decorative cover 3 is made of aluminum alloy. By using aluminum alloy to make the decorative cover, the aluminum alloy is lightweight and has good plasticity. The door frame body 1 will not be damaged when the decorative cover 3 is installed or removed. The aluminum alloy also has a certain degree of corrosion resistance, which can be used in humid environments, corrosive gas environments, etc., thus extending the service life of the decorative cover.

[0029] In this embodiment of the invention, a quick-installation door frame is first installed by inserting multiple fixing steel plates 2 into the slots 101 of the door frame body 1. The assembled door frame body 1 is then placed in the preset installation position, ensuring horizontal and vertical accuracy. Self-tapping screws 202 are then passed through bolt holes 201 and the door frame body 1 to secure the fixing steel plates 2 to the wall. The stability of the door frame is checked to ensure there is no looseness. Based on the opening direction and specifications of the door, the installation position of the hinges 205 on the fixing steel plates 2 is determined. The hinges 205 are then attached to the fixing steel plates 2, aligning with the bolt holes 201. 3. Use bolt 204 to pass through hinge 205 and bolt hole 203 to tighten the connection. Clean the debris in the slot 101. Align the snap-fit ​​structure 301 of the decorative cover 3 with the protrusion 102 of the door frame body 1. Press the decorative cover 3 firmly to ensure that the snap-fit ​​structure 301 is fully snapped into the protrusion 102. By installing and fixing the steel plate 2 in the slot 101, the traditional door frame milling process is eliminated, effectively avoiding milling deviation problems, greatly improving installation efficiency, simplifying the installation process, and installing the decorative cover 3 to hide the installation holes, making the door frame surface cleaner and more beautiful.
