[0002] Aluminum-wood doors are composite door and window products that combine the advantages of wood and aluminum alloy, possessing aesthetics, durability, and functionality. Aluminum-wood doors can be divided into two categories according to the location of the main material: aluminum-clad wood doors (aluminum on the outside and wood on the inside), where the interior side is solid wood or wood veneer and the exterior side is wrapped with thermally broken aluminum alloy profiles; and wood-clad aluminum doors (wood on the outside and aluminum on the inside), where the main body is an aluminum alloy frame and the exterior is covered with wood veneer or solid wood veneer.

[0003] In the prior art, the aluminum frame of aluminum-clad wooden doors has a concave structure, and it is mostly fixed to the wooden door by directly using glue. During use, the glue is prone to loosening and falling off due to aging. Based on this, a wooden door corner reinforcement frame is provided. Summary of the Invention

[0022] 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.

[0023] Please refer to Figures 1 to 6. In this embodiment of the utility model, a wooden door corner reinforcement frame includes a protective frame 5 for wrapping and protecting the four corners of the wooden door 1. The protective frame 5 is installed with the wooden door 1 through a concave clip 3. A concave groove 2 is pre-opened around the wooden door 1. The concave clip 3 is embedded in the concave groove 2 and fixed to the wooden door 1 by screws.

[0024] The inner side of the concave strip 3 is symmetrically fixed with raised strips 4, and the inner side of the protective frame 5 is folded to form a concave bending part 6. The ends of the two concave bending parts 6 are formed with arc-shaped raised parts 7.

[0025] The protective frame 5 is fitted onto the outer periphery of the wooden door 1 through two concave bends 6. The tops of the two concave bends 6 are inserted into the inner side of the concave groove 2, and the arc-shaped protrusions 7 and the protrusion strips 4 are interlocked and fixed to achieve the fixed assembly of the protective frame 5 and the wooden door 1.

[0026] A joint component 8 is also provided at the joint of the two protective frames 5. The joint component 8 is used to reinforce the joint of the two protective frames 5.

[0027] The docking assembly 8 includes a right-angle docking sleeve 801 and an I-shaped snap-fit ​​connector 802;

[0028] The I-shaped locking base 802 is symmetrically fixed to the ends of the two ends of the right-angle connecting sleeve 801. The right-angle connecting sleeve 801 is distributed in the diagonal middle of the two protective frames 5, and the two I-shaped locking bases 802 are respectively inserted into the inner side of the two protective frames 5 and the concave bending part 6, so as to realize the mutual limiting connection between the right-angle connecting sleeve 801 and the two protective frames 5.

[0029] Two raised strips 4 are provided on both sides of the inner wall of the concave clip 3. The arc-shaped raised part 7 is engaged in the middle of the two raised strips 4. The I-shaped locking seat 802 protrudes to the outside of the two concave bent parts 6, and the "convex" part of the I-shaped locking seat 80 is engaged between the innermost raised strip 4 and the inner wall end face of the concave clip 3.

[0030] In this embodiment, the installation steps for the protective frame 5 are as follows:

[0031] Beforehand, recessed grooves 2 are cut around the perimeter of the wooden door 1. The inner wall size of the recessed grooves 2 matches the outer wall size of the recessed clips 3. Then, according to the length of the four recessed grooves 2, the recessed clips 3 of the corresponding length are cut, and holes are made in the recessed clips 3. Then, the recessed clips 3 are inserted into each recessed groove 2, and screwed into the wooden door 1 through the holes to tighten them. This completes the installation of the recessed clips 3.

[0032] Next, cut protective frame 5 of the appropriate length according to the height and width of the wooden door 1 (it should be noted that the cut end of the protective frame 5 is connected to the bevel structure). Then, the protective frame 5 can be installed in the order of first the two sides and then the top and bottom. First, directly fit the protective frame 5 on both sides of the wooden door 1. The two concave folds 6 on the inner side of the protective frame 5 are attached to the front and rear end faces and sides of the wooden board 1, and the ends of the two concave folds 6 are inserted into the concave clips 3. When the arc-shaped protrusion 7 contacts the first protrusion 4, it is subjected to pressure. This pressure causes the end of the concave fold 6 to deform, so that the arc-shaped protrusion 7 can pass smoothly through the position of the first protrusion 4. When the arc-shaped protrusion 7 passes through the first protrusion 4, the end of the concave fold 6 returns to its original position under the elasticity of its own material, so that the arc-shaped protrusion 7 is engaged in the middle of the two protrusions 4. At this time, the installation of the side protective frame 5 is completed.

[0033] Next, install the upper and lower protective frames 5. First, install the two docking components 8 on both sides of the protective frame 5. Then, horizontally insert the I-shaped locking seat 802 into the middle of the inner side of the protective frame 5 and the outer side of the concave bending part 6. Then, bring the protective frame 5 close to the wooden board 1 so that it docks with the concave locking strips 3 at the upper and lower ends of the wooden board 1. The principle is the same as above. During this process, the bottom "convex" part of the I-shaped locking seat 802 that has docked with the protective frame 5 will contact the two protruding strips 4 in turn. The I-shaped locking seat 802 will shrink under force and move down smoothly. Finally, the bottom "convex" part of the I-shaped locking seat 802 will lock between the second protruding strip 4 and the inner end face of the concave locking strip 3. The other I-shaped locking seat 802 on the docking component 8 will be horizontally inserted into the side of the protective frame 5 and the inner side of the concave locking strip 3. This completes the installation of the upper and lower protective frames 5.

[0034] The above structure enables convenient assembly of the protective frame 5 and the wooden door 1. Compared with traditional adhesive fixing, it effectively avoids the problem of loosening and falling off due to glue aging, and effectively improves the installation stability of the protective frame 5. In addition, the docking component 8 and the joint of the two protective frames 5 can avoid sharp corners at the four corners of the frame structure assembled by the protective frame 5, making it safer to use. At the same time, the docking structure between the "convex" part at the bottom of the I-shaped locking seat 802 and the second protruding strip 4 further improves the connection between the end of the protective frame 5 and the wooden door 1.

[0035] Please refer to Figures 1-4. The concave strip 3 and the raised strip 4 are integrally formed by aluminum drawing process. The protective frame 5, the concave bending part 6, and the arc-shaped raised part 7 are integrally formed by aluminum drawing process. The right angle butt sleeve 801 and the I-shaped locking seat 802 are integrally formed by injection molding process.

[0036] In this embodiment, the diagonal component 8 has a certain degree of elasticity, making it safer to use. Meanwhile, the processing technology of the concave strip 3 and the protective frame 5 is the same as that of existing aluminum frames, facilitating improvements to existing equipment and promoting production and widespread use. The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on its technical solution and inventive concept, should be included within the scope of protection of this utility model.
