Description

Technical Field

[0001] This invention relates to the field of door panel technology, specifically to an adjustable-width door panel and its manufacturing method. Background Technology

[0002] In existing technologies, door panels manufactured both domestically and internationally are typically made with a fixed width. For ease of transport, door and window manufacturers usually do not assemble door frames and panels as a whole; instead, they are produced, transported, and installed separately as independent components. This leads to various problems during on-site installation, such as varying skill levels among installers, frame warping, and uneven door gaps, making it difficult for the door panel to fit properly. Installers often resort to tapping the side of the door panel to adjust it, which not only damages and deforms the panel but also affects its lifespan and aesthetics. Summary of the Invention

[0026] Preferably, the nut is located in the hexagonal hole at the bottom of the T-shaped door edge; the T-shaped door edge has a through hole for the screw to pass through.

[0027] Preferably, one or more sets (two or more sets) of telescopic adjustment devices are provided on the door side.

[0028] Preferably, the fastening device is disposed around the telescopic adjustment device, and the fastening device includes: a bolt; the bolt passes through the T-shaped door edge and the U-shaped groove.

[0029] Preferably, the telescopic adjustment device drives the T-shaped door edge to move outwards into the U-shaped groove, forming a concave strip between the door edge and the frame.

[0030] This embodiment also provides a method for manufacturing an adjustable-width door leaf, the method comprising: pressing the door skin, filling material and frame together; setting the telescopic adjustment device on the T-shaped door edge; and fixing the T-shaped door edge in the U-shaped groove of the frame by a fastening device.

[0031] Optionally, after loosening the fastening device, adjust the telescopic adjustment device, and use the telescopic adjustment device to move the T-shaped door edge within the U-shaped groove to adjust the door width, then tighten the fastening device.

[0032] Preferably, a method for manufacturing an adjustable-width door leaf specifically includes: Step A1: Press the door skin, filling material, and frame together; Step A2: Pre-drill hexagonal holes at the bottom of the T-shaped door edge corresponding to the nuts, and install the nuts into the hexagonal holes; drill through holes at the top of the T-shaped door edge corresponding to the hexagonal holes so that the screw can pass through; fit the screw onto the nut; Step A3: Secure the T-shaped door edge to the U-shaped groove of the frame using bolts.

[0033] This embodiment provides an adjustable-width door leaf and its manufacturing method. By setting a telescopic adjustment device on the door edge, the telescopic adjustment device drives the T-shaped door edge to move within the U-shaped groove to adjust the width of the door leaf, thereby ensuring the adaptability of the door leaf on the construction site, avoiding damage to the door edge, and ensuring the service life and aesthetics of the door leaf. Example 2

[0034] like Figures 1-7 As shown, this embodiment provides an adjustable-width door leaf including a door skin 11, a door skin 12, a frame 13, filling material, and a door edge 3. The frame 13 is provided with a U-shaped groove, and the door edge 3 is T-shaped; the T-shaped door edge structure is adapted to the U-shaped groove structure; the door edge 3 has two sets of telescopic adjustment devices 2, each including a screw 21, a nut 22, and a washer 23. Each set of telescopic adjustment devices 2 is surrounded by four bolts 24 for fixing the door edge 3 and the frame 13.

[0035] It should be noted that one or more sets of telescopic adjustment devices can be installed on the door edge, preferably three or more sets of telescopic adjustment devices.

[0036] This invention provides a method for manufacturing an adjustable-width door leaf, comprising: Step 1: Press the door skin 11, door skin 12, and filling material together, and place the U-shaped groove of the frame 13 and the hinge on one side.

[0037] Step 2: Pre-drill hexagonal holes on door edge 3 corresponding to nut 22, and install nut 22 into the hexagonal holes. Drill through holes at the positions corresponding to the hexagonal holes on door edge 3, allowing screw 21 to pass through. Fit screw 21 onto nut 22.

[0038] Step 3: Fix the door edge 3, which is already equipped with the telescopic adjustment device 2, to the frame 13 with bolts 24.

[0039] It should be noted that, in order to ensure the stability of the door leaf size after adjustment, the shim 23 can be glued to the U-shaped groove of the frame 13 at the position corresponding to the screw 21 of the telescopic adjustment device 2. Then, the door edge 3 is placed into the U-shaped groove, and the door edge 3 and the frame 13 are locked and fixed by the bolt 24 to obtain the desired door leaf.

[0040] After the door leaf arrives at the installation site, if the door leaf width needs to be adjusted according to the inner width of the door frame, first loosen the bolts 24 on the door edge 3. Then, adjust the screw 21 through the through hole of the telescopic door edge 3. The screw 21, moving spirally within the nut 22, will cause the door edge 3 to move within the U-shaped groove of the frame 13, adjusting the door leaf to the appropriate width. After adjusting the door leaf to the appropriate width, tighten the fixing bolts 24 to obtain a door leaf of the appropriate width. It should also be noted that as the screw 21 moves spirally within the nut 22, causing the door edge 3 to move outward within the U-shaped groove of the frame 13, a corresponding concave strip will appear between the door edge and the frame, making the adjusted door leaf more aesthetically pleasing.

[0041] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
