[0030] Please see Figures 1-6As shown, this utility model is an aluminum door frame that is easy to disassemble and maintain. It includes an outer aluminum door frame 1, with protective covers 11 on both the front and back. An inner aluminum door frame 12 is inserted into the inner side of the outer aluminum door frame 1, and a mounting frame 14 is fixedly connected to the inner side of the outer aluminum door frame 1. The inner aluminum door frame 12 has several insertion holes 121 inside, and several magnetic blocks 122 are embedded on its back. The outer aluminum door frame 1 is fixed to the wall with expansion bolts, and the inner aluminum door frame 12 is inserted into the outer aluminum door frame 1 and fixed with bolts. Through the double-layer design of the outer aluminum door frame 1 and the snap-fit ​​assembly 2, only the inner aluminum door frame 12 needs to be removed during disassembly and maintenance. This not only makes disassembly more convenient but also avoids violent disassembly, protecting the aluminum door frame from secondary damage. It also includes:

[0031] The buckle assembly 2 consists of several sets, and each set of buckle assembly 2 is located on the front and back of the outer aluminum door frame 1. The buckle assembly 2 is used to connect and fix the protective cover 11. Both the outer aluminum door frame 1 and the protective cover 11 are hollow inside. The outer aluminum door frame 1 is connected to the wall by expansion bolts.

[0032] Several positioning rods 13 are fixedly connected to the front and back of the outer aluminum door frame 1, and several threaded holes are opened inside the mounting frame 14; after the inner aluminum door frame 12 is installed inside the outer aluminum door frame 1, the insertion hole 121 will correspond to the threaded hole on the mounting frame 14.

[0033] The inner aluminum door frame 12 is installed on the back of the outer aluminum door frame 1 and will contact the front of the mounting frame 14. The magnetic block 122 is used to attach the inner aluminum door frame 12 to the mounting frame 14.

[0034] The protective cover 11 has several slots 111 and several positioning holes 112 on the side facing the outer aluminum door frame 1. The slots 111 correspond to the buckle assembly 2, and the positioning holes 112 are adapted to the positioning rod 13. The inner diameter of the positioning hole 112 is slightly larger than the diameter of the positioning rod 13. The protective cover 11 is used to cover the outer aluminum door frame 1 and the buckle assembly 2.

[0035] The buckle assembly 2 includes a mounting plate 21 that is inserted into the outside of the outer aluminum door frame 1. Two clips 22 are fixedly connected to the side of the mounting plate 21 facing the protective cover 11. A spring 23 is fixedly connected to the side of the two clips 22 that are close to each other. After the inner aluminum door frame 12 is installed inside the outer aluminum door frame 1, the protective cover 11 is installed by aligning it with the outer aluminum door frame 1. The clip groove 111 will contact the clip 22 and push it. At this time, the spring 23 is compressed. When the protrusion on the clip 22 enters the clip groove 111, it will spring back to its original position. At this time, the protective cover 11 is quickly installed, covering the outer aluminum door frame 1 and the inner aluminum door frame 12, improving the aesthetics.

[0036] Mounting plate 21 is fixedly connected to the outer aluminum door frame 1 by screws. Spring 23 is used to assist the card plate 22 in rebounding and resetting. The side of card plate 22 facing the protective cover 11 is set with an angle, and the sides of the two card plates 22 that are far apart from each other are set with V-shaped protrusions.

[0037] One specific application of this embodiment is:

[0038] Position the outer aluminum door frame 1 at the door frame location on the wall, and then use expansion screws to fix the outer aluminum door frame 1 to the wall. After the outer aluminum door frame 1 is installed, insert the inner aluminum door frame 12 into the inside of the outer aluminum door frame 1. The back of the inner aluminum door frame 12 will then contact the mounting frame 14. Since the mounting frame 14 is made of stainless steel (such as 409, 410, and 430), the magnetic block 122 will be magnetically attracted to the mounting frame 14. At this time, the insertion hole 121 on the inner aluminum door frame 12 will align with the threaded hole on the mounting frame 14. Then, insert the bolt into the insertion hole 121 and align it with the threaded hole on the mounting frame 14. The inner aluminum door frame 12 is fixed by a threaded connection. After the inner aluminum door frame 12 is installed, the protective cover 11 is installed by connecting it to the positioning rod 13 on the outside of the outer aluminum door frame 1 through the positioning hole 112. The positioning rod 13 positions the protective cover 11. Then the slot 111 contacts the plate 22 and pushes the plate 22. At this time, the spring 23 is compressed. When the protrusion on the plate 22 enters the slot 111, the spring force of the spring 23 will spring the plate 22 back to its original position. At this time, the protective cover 11 is stably attached to the outer aluminum door frame 1, covering the outer aluminum door frame 1 and the inner aluminum door frame 12, improving the aesthetics.

[0039] When disassembly and maintenance are required, pull the protective cover 11 forcefully to disengage the clip 22 from the slot 111, and then remove the protective cover 11. Then, remove the bolts on the inner aluminum door frame 12, and pull the inner aluminum door frame 12 forcefully to disengage the magnetic block 122 from the mounting frame 14, and then remove the inner aluminum door frame 12. This method uses a double-layer setting of the outer aluminum door frame 1 and the clip assembly 2. During disassembly and maintenance, only the inner aluminum door frame 12 needs to be removed, which is not only more convenient for disassembly, but also avoids violent disassembly. At the same time, the mounting plate 21 on the outer aluminum door frame 1 is installed with screws. When the clip 22 becomes fatigued, remove the screws on the mounting plate 21 to remove the mounting plate 21 and replace it.
