Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-7 A modular aluminum alloy door frame includes a top frame 1 made of aluminum alloy, with two vertically extending side frames 2 at its bottom. Each side frame 2 has an insert 3 machined at its top. During the machining process, the bottom of the top frame 1 is provided with two slots 5 that are adapted to the insert 3. The insert 3 is a cuboid structure, so that the side frame 2 will not rotate relative to the top frame 1 after the insert 3 is inserted into the slot 5.

[0023] To lock the relative positions of the top frame 1 and the side frame 2, two limiting grooves 6 are provided at the bottom of the top frame 1. A limiting plate 7 is connected to the limiting grooves 6 by three telescopic rods 10. The size of the limiting grooves 6 is sufficient for the operator to move the limiting plate 7. The telescopic rods 10 prevent the limiting plate 7 from disengaging from the limiting grooves 6, but also allow the limiting plate 7 to move laterally within the limiting grooves 6. A limiting block 8 extending into the slot 5 is fixedly welded to the side of the limiting plate 7. A mating groove 9 that matches the limiting block 8 is provided on one side of the insert 3. The side of the limiting block 8 away from the limiting plate 7 is movably inserted into the mating groove 9. The lateral movement within the slot 6 can be completed manually. To lock the limiting plate 7 in the position within the slot 6, an upward-extending screw 11 is threaded to the bottom of the limiting plate 7, with the top of the screw 11 penetrating through the limiting plate 7 and the end threaded to the top frame 1. This completes the assembly of the top frame 1 and the side frame 2, forming a basic frame. The side frame 2 also has several holes for bolts or expansion bolts to pass through. By using bolts through these holes, the side frame 2 can be mounted to the wall. These holes need to be internal, meaning that when the bolt or expansion bolt passes through the hole, its nut is hidden inside the side frame 2. The internal holes are designed as follows: Figure 7 As shown.

[0024] A decorative panel 4 is provided on the exterior-facing side of the entire frame. The side of the decorative panel 4 facing away from the top frame 1 has a conventional pattern or a raised / recessed design, which is existing technology. The main improvement of this technical solution is the ease of decoration and replaceability of the decorative panel 4. A groove 12 is provided on the side of the side frame 2, and a slider 14 is fixedly connected to the rear side of the decorative panel 4 using a protrusion 13. The slider 14 is adapted to the groove 12. The front opening of the groove 12 is smaller than the size of the slider 14, while the notch at its top is the same size as the slider 14. This allows the decorative panel 4 to be easily replaceable. When the bottom horizontal line is higher than the bottom horizontal line of the side frame 2, the worker can push the slider 14 into the slide groove 12 through the notch above the slide groove 12, and then slowly release the decorative panel 4. Due to gravity, the slider 14 will gradually slide down in the slide groove 12. When the bottom of the slider 14 contacts the bottom of the inner wall of the slider 12, the bottom surface of the decorative panel 4 will be at the same level as the bottom surface of the side frame 2. At this time, the back side of the decorative panel 4 is also in contact with the side frame 2. Due to the small size of the groove opening on the front side of the slide groove 12, the slider 14 moves directly forward and will not detach from the slide groove 12.

[0025] To lock the vertical position of the decorative panel 4, a limiting groove 2 15 is provided at the center of the bottom of the top frame 1. A telescopic rod 2 16 is fixedly connected to the rear side of the inner wall of the limiting groove 2 15, and a limiting plate 2 17 located inside the limiting groove 2 15 is fixedly connected to the extended end of the telescopic rod 2 16. A spring 20 is sleeved on the surface of the telescopic rod 2 16. One end of the spring 20 is fixedly connected to the top frame 1, and the other end is fixedly connected to the limiting plate 2 17. The size of the limiting groove 2 15 is sufficient for the operator to manually move the limiting plate 2 17. The spring 20 is designed to stabilize the position of the limiting plate 2 17 within the limiting groove 2 15. The deformation of the spring 20 requires... The spring 20 provides the force, so when no one pulls the limiting plate 2 17, the elasticity of the spring 20 will resist the limiting plate 2 17. The side of the limiting plate 2 17 away from the telescopic rod 2 16 is fixedly connected to a limiting rod 18 that extends to the outside of the top frame 1. The back side of the decorative panel 4 is provided with a back groove 19 whose diameter is adapted to the limiting rod 18. The end of the limiting rod 18 away from the limiting plate 2 17 is movably inserted into the back groove 19, thus limiting the decorative panel 4 so that it will not move upward. As can be seen from the above description, whether it is the vertical assembly of the decorative panel 4 and the frame, or the locking operation of the subsequent limiting rod 18 and other structures, it can be completed manually by the staff, which is convenient.

[0026] Finally, in this technical solution, the top frame 1, the side frame 2, and the insert block 3 are all made of aluminum alloy.

[0027] In use, the ease of operation is illustrated by separating the top frame 1, side frame 2, and decorative panel 4. The operator moves the second limiting plate 17, compressing the second telescopic rod 16 and spring 20. The second limiting plate 17 then moves the limiting rod 18, causing it to disengage from the back groove 19. A suction cup or a high-friction object is then used to adhere to the side of the decorative panel 4, causing it to move upwards. The decorative panel 4, via the protrusion 13, moves the slider 14 upwards within the groove 12. When the slider 14 aligns with the uppermost notch of the groove 12, the decorative panel 4 moves away from the side frame 2, thus separating it from the side frame 2. The decorative panel 4 can also be replaced. When the screw 11 is tightened with a screwdriver, it disengages from the top frame 1. The operator then moves the first limiting plate 7, shortening the first telescopic rod 10. The first limiting plate 7 then moves the limiting block 8 out of the mating groove 9, allowing the top frame 1 and side frame 2 to be separated.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
