Description

Technical Field

[0001] This application relates to the field of furniture technology, and more specifically, to an aluminum-wood composite door with a deformation-resistant structure. Background Technology

[0002] Wooden doors are a common choice for home doors, but they are prone to warping after long-term use, and they are also relatively expensive and heavy. Therefore, for taller doors, aluminum profiles are usually used as the frame, and wood veneer is wrapped around the frame to form an aluminum-wood composite door.

[0003] Because a lock body needs to be installed on the door, a large lock hole needs to be made in the frame, which interrupts the structure of the frame and reduces the overall strength. Utility Model Content

[0004] To overcome the above deficiencies, this application provides an aluminum-wood composite door with an anti-deformation structure, which aims to improve the problems mentioned in the background art.

[0005] This application provides an aluminum-wood composite door with a deformation-resistant structure, including an inner frame, an outer frame, a panel, and a vertically installed keel. The outer frame is fastened to the inner frame, and the panel is fixedly attached to both sides of the inner frame. The outer frame is fixedly attached to the end face of the panel. The keel includes a square tube, and adapters are inserted into both ends of the square tube. The adapters are screwed to the inner frame, and a W-shaped reinforcing rib is fixedly connected inside the square tube.

[0006] In one specific implementation, the square tube and the reinforcing rib are integral profiles, the adapter is adapted to the reinforcing rib, and the inner wall of the adapter is provided with self-tapping screw holes.

[0007] In the above process, the adapter is first fixed to the inner wall of the inner frame with self-tapping screws. When the inner frame is assembled, the square tube is inserted into the adapter. The adapter has W-shaped and rectangular slots that can fit tightly with the square tube and reinforcing ribs.

[0008] In one specific implementation, the outer frame includes a buckle strip, which has a stepped structure and has a slot on it that is adapted to the inner frame and the panel.

[0009] In the above implementation process, the stepped buckle itself has strong structural strength. After the panel and the inner frame are fixedly attached, the buckle is fastened to the inner frame to form a good snap-fit ​​effect with the inner frame. Then the buckle also wraps around the end face of the panel to form a wrapping and fixing effect on the panel.

[0010] In one specific implementation, the outer wall of the buckle strip is provided with a bevel.

[0011] In the above process, the beveled surface abuts against the sealing strip on the door frame, resulting in a better sealing effect.

[0012] In one specific implementation, the outer frame further includes an outer corner code, and adjacent buckles are connected at a 45-degree angle through the outer corner code.

[0013] In the above implementation process, the outer corner brackets are first fixed to the buckle strips on both sides. Screws are then tightened from the inside of the outer corner brackets outwards. This way, the screw holes are not visible on the buckle strips on both sides, which is aesthetically pleasing. After the buckle strips at the top and bottom are installed on the inner frame and panel, the buckle strips on both sides, along with the outer corner brackets, are inserted inwards. At this time, screws are tightened inwards from the outer end of the buckle strips. Since the screw holes are located at the top and bottom of the door, they are not easily seen, which also ensures the aesthetic effect. The setting of the outer corner brackets can effectively reduce the situation where the buckle strips curl up and affect the aesthetics.

[0014] In one specific implementation, the center of the inner frame is filled with filler.

[0015] In the above implementation process, after the inner frame and the keel are fixed, filler is used to fill the gaps in the inner frame.

[0016] In one specific implementation, the inner frame includes a frame strip, the cross-section of which has several chambers, and the mating surfaces of the frame strip, the buckle strip, and the panel are all corrugated.

[0017] In the above implementation process, the cross-section of the frame strip has four chambers, which can improve its own structural strength. After the buckle strip and the frame strip are fastened together, glue is applied to the corrugated part to ensure the connection strength. Glue is applied to both sides of the frame strip to facilitate panel bonding and fixing.

[0018] In one specific implementation, the inner frame further includes an inner corner code, and adjacent frame strips are connected at a 45-degree angle by the outer corner code.

[0019] In the above implementation process, after splicing the four inner corner brackets and the four frame strips together, screws are screwed in from the side of the frame strips to fix the frame strips and inner corner brackets together. The inner corner brackets are tightly inserted into the corresponding cavities in the frame strips, which plays a good connecting role.

[0020] Compared with the prior art, the beneficial effects of this application are: the outer frame is fastened to the inner frame to form an edge that ensures aesthetics, and the two become one, which improves the structural strength. The keel can compensate for the strength reduction caused by the lock groove on the inner frame. The reinforcing ribs with W-shaped cross sections improve the strength of the entire aluminum-wood composite door and have a good anti-deformation effect. The adapter can be easily installed in the appropriate position on the inner frame. The square tube adopts a plug-in method, which also ensures the connection strength between the keel and the inner frame. Attached Figure Description

[0028] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0029] Please see Figures 1-5This application provides an aluminum-wood composite door with a deformation-resistant structure, including an inner frame 10, an outer frame 20, a panel 30, and a vertically installed keel 40. The outer frame 20 is fastened to the inner frame 10. The panels 30 are fixedly attached to both sides of the inner frame 10. The outer frame 20 is fixedly attached to the end face of the panel 30. The keel 40 includes a square tube 41. The two ends of the square tube 41 are inserted with adapter seats 42. The adapter seats 42 are screwed to the inner frame 10. A W-shaped cross-section reinforcing rib 43 is fixedly connected inside the square tube 41. The outer frame 20 is fastened to the inner frame 10 to form an edge, ensuring aesthetics. The two become one, improving structural strength. The keel 40 can compensate for the strength reduction caused by the lock groove on the inner frame 10. The W-shaped cross-section reinforcing rib 43 improves the strength of the entire aluminum-wood composite door and has a good anti-deformation effect. The adapter 42 can be easily installed at an appropriate position on the inner frame 10. The square tube 41 adopts a plug-in method, which also ensures the connection strength between the keel 40 and the inner frame 10.

[0030] Please see Figures 1-5 The square tube 41 and the reinforcing rib 43 are integral profiles. The adapter 42 is compatible with the reinforcing rib 43, and the inner wall of the adapter 42 has self-tapping screw holes. The adapter 42 is first fixed to the inner wall of the inner frame 10 with self-tapping screws. When the inner frame 10 is assembled, the square tube 41 is inserted into the adapter 42. The adapter 42 has W-shaped and rectangular slots, which can fit tightly with the square tube 41 and the reinforcing rib 43.

[0031] Please see Figures 1-5 The outer frame 20 includes a retaining strip 21, which has a stepped structure and has slots that fit the inner frame 10 and the panel 30. The stepped retaining strip 21 itself has strong structural strength. After the panel 30 is fixedly attached to the inner frame 10, the retaining strip 21 is fastened to the inner frame 10 to form a good snap-fit ​​effect. Then, the retaining strip 21 also wraps around the end face of the panel 30, forming a wrapping and fixing effect on the panel 30.

[0032] Please see Figures 1-5 The outer wall of the snap strip 21 is provided with a bevel 22. The bevel 22 abuts against the sealing strip on the door frame, which has a better sealing effect.

[0033] Please see Figures 1-5The outer frame 20 also includes outer corner brackets 23, and adjacent latching strips 21 are connected at 45 degrees through the outer corner brackets 23. The outer corner brackets 23 are first fixed to the latching strips 21 on both sides, and screws are tightened from the inside of the outer corner brackets 23 outwards. This way, the screw holes are not visible on the latching strips 21 on both sides, which is good for aesthetics. After the latching strips 21 at the top and bottom are installed on the inner frame 10 and the panel 30, the latching strips 21 on both sides with the outer corner brackets 23 are inserted inwards. At this time, screws are tightened inwards from the outside of the latching strips 21. Since the screw holes are located at the top and bottom of the door, they are not easily seen, which also ensures the aesthetic effect. The setting of the outer corner brackets 23 can effectively reduce the situation where the latching strips 21 warp and affect the aesthetics.

[0034] Please see Figures 1-5 The center of the inner frame 10 is filled with filler 50. After the inner frame 10 and the keel 40 are fixed, filler 50 is used to fill the gaps in the inner frame 10.

[0035] Please see Figures 1-5 The inner frame 10 includes a frame strip 11. The cross-section of the frame strip 11 has several chambers. The mating surfaces of the frame strip 11 with the buckle strip 21 and the panel 30 are corrugated. The cross-section of the frame strip 11 has four chambers, which can improve its structural strength. When the buckle strip 21 and the frame strip 11 are fastened together, glue is applied to the corrugated areas to ensure the connection strength. Glue is applied to both sides of the frame strip 11 to facilitate the adhesion and fixation of the panel 30.

[0036] Please see Figures 1-5 The inner frame 10 also includes inner corner brackets 12, and adjacent frame strips 11 are connected by outer corner brackets 2345 degrees. After the four inner corner brackets 12 and the four frame strips 11 are spliced ​​together, screws are screwed in from the side of the frame strips 11 to fix the frame strips 11 and the inner corner brackets 12 together. The inner corner brackets 12 are tightly inserted into the corresponding cavities in the frame strips 11, which plays a good connecting role.

[0037] The working principle of this anti-deformation aluminum-wood composite door is as follows: A groove is cut into the frame strip 11 to facilitate the installation of the lock body. Based on the volume of the lock body, the keel 40 is installed as close as possible to the lock body. First, the adapter 42 is fixed to the inner wall of the upper and lower frame strips 11 with self-tapping screws. Then, the square tube 41 is inserted into the upper and lower adapter 42, thus determining the position of the upper and lower frame strips 11. Next, the inner corner brackets 12 and the left and right frame strips 11 are installed. One panel 30 is fixed and attached to one side of the inner frame 10. Then, filler 50 is filled into the center of the inner frame 10, and then the other panel 30 is covered. Next, the outer corner brackets 23 are first fixed to the side latches 21, and screws are tightened from the inside of the outer corner brackets 23 outwards. This way, the screw holes are not visible on the side latches 21, which is aesthetically pleasing. The upper and lower... After the end of the buckle strip 21 is installed on the inner frame 10 and the panel 30, the buckle strips 21 on both sides with the outer corner brackets 23 are inserted inward. At this time, screws are screwed in from the outer end of the buckle strip 21. Since the screw holes are located at the top and bottom of the door, they are not easily seen, which also ensures the aesthetic effect. In summary, the outer frame 20 is fastened to the inner frame 10 to form an edge to ensure the aesthetic effect. The two become one and improve the structural strength. The keel 40 can make up for the strength reduction caused by the lock groove on the inner frame 10. The W-shaped cross-section reinforcing rib 43 improves the strength of the entire aluminum-wood composite door and has a good anti-deformation effect. The adapter 42 can be easily installed on the appropriate position on the inner frame 10. The square tube 41 adopts the plug-in method, which also ensures the connection strength between the keel 40 and the inner frame 10.

[0038] It should be noted that, for ease of demonstration, the proportions of the outer frame 20, inner frame 10, and keel 40 in the attached diagram have been enlarged.
