Abstract
Description
Technical Field
[0001] This utility model relates to the field of door frame technology, specifically a minimalist door frame. Background Technology
[0002] Traditional door frame structures generally suffer from the following pain points:
[0003] 1. Traditional door frames typically have a visible width of ≥45mm, creating a clear dividing line with the wall and disrupting the minimalist design style of the space;
[0004] 2. It requires splicing of multiple components (such as door frame trim and edge trim), which is time-consuming to construct and requires high precision.
[0005] 3. Gaps can easily form between the door leaf and the door frame due to deformation, resulting in poor sound insulation and insufficient air tightness;
[0006] 4. It is difficult to adapt to diverse decorative needs such as stainless steel and wood veneer, which limits design flexibility.
[0007] While existing minimalist door frame designs reduce the visible surface area, they generally suffer from weak load-bearing capacity and poor durability during opening and closing. Therefore, we propose a minimalist door frame design to address these issues. Utility Model Content
[0008] The purpose of this invention is to provide a minimalist door frame to solve the problems mentioned in the background art.
[0009] To achieve the above objectives, this utility model provides the following technical solution:
[0010] A minimalist door frame includes a door body and a door frame. The door frame is fixedly installed on the inner wall of a door frame groove in the wall, and the door body is installed inside the door frame, forming an inward-opening door.
[0011] The door frame includes a main door frame sleeve for mounting the inner wall of the door frame groove. An inner wall connecting block is fixedly installed on one end of the main door frame sleeve, and the inner wall connecting block is fixedly installed on the inner surface of the wall. A door stop is fixedly installed on the other end of the main door frame sleeve near the door body. A rubber strip is installed on the side of the door stop facing the door body. A door stop groove that matches the rubber strip is opened on the inner side of the door body. An installation groove is opened on the other side of the door stop. A secondary door sleeve is fixedly installed inside the installation groove. One end of the secondary door sleeve extends to the outer side of the wall. An outer wall decorative panel is fixedly installed on one end of the secondary door sleeve, and the outer wall decorative panel is fixedly installed on the outer surface of the wall.
[0012] Preferably, bolts are provided on the main door frame, and the main door frame is fixed to the wall by the bolts. The gap between the main door frame and the wall is filled with glue.
[0013] Preferably, the door sleeve is made of stainless steel.
[0014] Preferably, the door sub-sleeve is a wooden base sleeve structure.
[0015] Preferably, the door sleeve is a profile sleeve structure.
[0016] Preferably, the inner wall connecting block and the outer wall decorative panel are nine millimeters thick.
[0017] Compared with the prior art, this utility model provides a minimalist door frame with the following advantages:
[0018] This minimalist door frame has an exposed structure of only 9mm, reducing the visual volume by 80% compared to a traditional 45mm door frame, achieving a minimalist effect of door-wall integration. By creating a door stop groove on the inside of the door that matches the rubber strip, when the door is closed, both the rubber strip and the door stop are filled in the door stop groove, forming a hidden door stop structure. This not only meets safety standards but also avoids damaging the integrity of the narrow frame lines, and also achieves a tight fit between the door frame and the door leaf, improving sound insulation and airtightness.
[0019] This minimalist door frame can be customized with different materials for the secondary door frame and decorative surfaces, such as stainless steel frame structure and wooden base frame structure, to meet the needs of different users. It is designed with a targeted structure to resist the risk of deformation caused by long-term opening and closing, especially considering the characteristics of inward opening and closing.

[0028] Please see Figure 1-4 A minimalist door frame includes a door body 2 and a door frame. The door frame is fixedly installed on the inner wall of the door frame groove on the wall 1, and the door body 2 is installed inside the door frame, which is an inward-opening door.
[0029] The door frame includes a main door frame sleeve 3 for mounting the inner wall of the door frame groove. An inner wall connecting block 4 is fixedly installed on one end surface of the main door frame sleeve 3. The inner wall connecting block 4 is fixedly installed on the inner surface of the wall 1. A door stop 5 is fixedly installed on the other end of the main door frame sleeve 3 near the door body 2. A rubber strip 6 is installed on the side of the door stop 5 facing the door body 2. A door stop groove that matches the rubber strip 6 is opened on the inner side of the door body 2. When the door is closed, the rubber strip 6 and the door stop 5 are filled in the door stop groove to form a hidden door stop structure, which meets safety standards and avoids damaging the integrity of the narrow frame lines.
[0030] When the door frame is under stress, the load of the door body 2 is transferred to the main frame 3 and the inner connecting block 4, and then to the wall. The main frame 3 and the inner connecting block 4 can simultaneously distribute the stress, thus avoiding local deformation of the door frame.
[0031] An installation groove is provided on the other side of the door stop 5. A door sub-sleeve 7 is fixedly installed inside the installation groove. One end of the door sub-sleeve 7 extends to the outside of the wall 1. An outer wall decorative panel 8 is fixedly installed at one end of the door sub-sleeve 7. The outer wall decorative panel 8 is fixedly installed on the outer surface of the wall 1.
[0032] Furthermore, the inner wall connecting block 4 and the outer wall decorative panel 8 are 9 mm thick, which reduces the visual volume by 80% compared to the traditional 45 mm door frame, achieving a minimalist effect of door and wall integration.
[0033] The main door frame 3 is equipped with bolts, which are used to fix the main door frame 3 to the wall 1. The gap between the main door frame 3 and the wall 1 is filled with adhesive, which is expanding foam. This not only improves the sealing effect between the door frame and the wall, but also blocks the sound bridge transmission between the door frame and the wall, thus improving the sound insulation effect of the door frame.
[0034] Example 1, see Figure 5 The door sleeve 7 is made of stainless steel.
[0035] Example 2, see Figure 6 The door sub-sleeve 7 is a wooden seat structure.
[0036] Example 3, see Figure 7 The door accessory sleeve 7 is a profile sleeve structure.
[0037] The door frame can be fitted with different materials for the secondary door frame 7 and decorative surfaces, which can meet the needs of different users and improve the adaptability of the device.
[0038] Working principle: This minimalist door frame has an exposed structure of only 9mm, reducing the visual volume by 80% compared to the traditional 45mm door frame, achieving a minimalist effect of door-wall integration. By creating a door stop groove on the inner side of the door body 2 that matches the rubber strip 6, when the door is closed, both the rubber strip 6 and the door stop 5 are filled in the door stop groove, forming a hidden door stop structure. This not only meets safety standards but also avoids damaging the integrity of the narrow frame lines. It also achieves a tight fit between the door frame and the door leaf, improving sound insulation and airtightness. Different materials for the secondary door frame 7 and decorative surfaces, such as stainless steel frame structures and wooden base frame structures, can be used according to needs to meet the usage needs of different users. A targeted structure is designed for the inward-opening and inward-flat characteristics to resist the risk of deformation caused by long-term opening and closing.
