DETAILED DESCRIPTION

[0038] The present invention discloses an inward-opening door leaf assembly door frame, wherein the auxiliary frame support is made of aluminum honeycomb panels and can be cut on-site to match the actual thickness of the door opening wall, thereby preventing the door frame from being unable to be installed on-site. The present invention also discloses an inward-opening door leaf assembly using the above-mentioned door frame, which is suitable for door opening walls of various thicknesses.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] See also Figure 1-Figure 5 , an embodiment of the present invention provides a door frame 300 of an inward-opening door leaf assembly, including an auxiliary frame upright 302, an indoor side flat line 301 and an outdoor side flat line 303; the auxiliary frame upright 302 is used to be arranged on the side of the door opening wall 100; the auxiliary frame upright 302 is an aluminum honeycomb panel; the indoor side flat line 301 is connected to one side of the auxiliary frame upright 302 and is positioned on the indoor side in the thickness direction of the door opening wall 100; the outdoor side flat line 303 is connected to the other side of the auxiliary frame upright 302 and is positioned on the outdoor side in the thickness direction of the door opening wall 100, and the outdoor side flat line 303 is a metal outdoor side flat line; the side of the outdoor side flat line 303 facing the door leaf 200 protrudes from the auxiliary frame upright 302 to form a door closing limit portion 3035; the door closing limit portion 3035 is located at the edge of the outdoor side flat line 303 facing the outdoor.

[0041] In the above-mentioned door frame 300, the auxiliary frame uprights 302 are made of aluminum honeycomb panels, which can be cut on site to adapt to the actual thickness of the door opening wall 100, preventing the door frame 300 from being unable to be installed on site.

[0042] In addition, the auxiliary cover stand 302 uses aluminum honeycomb panels that can be cut into any width. Compared with the solution of using multiple aluminum alloy gusset plates to be spliced in sequence along the thickness direction of the door opening wall 100 to form the auxiliary cover stand 302, it avoids the formation of splicing seams on the auxiliary cover stand 302, eliminates the splicing operation, and helps to improve the installation efficiency of the door cover 300.

[0043] Furthermore, in the door frame 300, the exterior flat panel line 303 forms a door closing stop 3035, allowing the accompanying door leaf 200 to be assembled to the exterior flat panel line 303. This allows the door leaf 200 to remain flush or nearly flush with the exterior side of the door opening wall 100 when viewed from the outside, rather than close to the interior side of the door opening wall 100. This prevents the door leaf 200 from being viewed from the outside, thus maintaining a high level of cleanliness on the exterior side of the door and meeting the customer's aesthetic requirements. Furthermore, the door closing stop 3035 is located at the exterior edge of the exterior flat panel line 303, blocking the closed door leaf 200 from the outside, allowing the door leaf 200 to open inward, which is more in line with the living habits of people in a home environment.

[0044] In the above-mentioned door frame 300, the outdoor flat line 303 includes a main body 3031 and a line contact portion 3037 fixedly connected to the main body 3031; the main body 3031 is used to be attached to the side of the door opening wall 100; the line contact portion 3037 is used to be attached to the outdoor surface of the door opening wall 100.

[0045] In the door frame 300 provided in this embodiment, the outdoor flat panel 303 integrates a main body 3031, which functions as the main frame, and a wire contact portion 3037, which functions as the door frame line. This allows the outdoor flat panel 303 to cooperate with the door leaf 200 while also covering the gap between the main body 3031 and the door opening wall 100 from the outdoor side. The main body 3031 and wire contact portion 3037 are an integrated structure, eliminating the need for on-site assembly, thereby improving the assembly efficiency of the door frame 300. Furthermore, to facilitate manufacturing and save costs, the outdoor flat panel 303 is configured as an aluminum alloy.

[0046] like Figure 1 As shown, the surface of the indoor flat panel line 301 facing the outside of the doorway wall 100 is provided with a protrusion, which allows the indoor flat panel line 301 to contact and abut against the indoor side line of the doorway wall 100. Line contact provides greater tolerance and stability than surface contact. The surface of the line contact portion 3037 facing the outside of the doorway wall 100 may also be provided with a protrusion, which allows the outdoor flat panel line 303 to contact and abut against the outdoor side line of the doorway wall 100.

[0047] The main body 3031 of the outdoor flat line 303 has a first fixing clamping groove 3032, and one end of the outdoor side of the auxiliary sleeve stand 302 is embedded in the first fixing clamping groove 3032 and fixed by a fastener; the door closing limit part 3035 is arranged on the side of the main body 3031 facing the door leaf 200.

[0048] A surface of the main body 3031 facing the door leaf 200 is a side surface 3033 reserved for door closing. The side surface 3033 reserved for door closing protrudes from the auxiliary sleeve upright 302 , and the door closing limit portion 3035 protrudes from the side surface 3033 reserved for door closing.

[0049] The surface of the main body 3031 facing the outside of the room, the surface of the line contact portion 3037 facing the outside of the room, and the surface of the door closing limit portion 3035 facing the outside of the room are flush and connected as a whole.

[0050] In the solution provided in this embodiment, the surface of the main body 3031 facing the outside, the surface of the line contact part 3037 facing the outside, and the surface of the door closing limit part 3035 facing the outside are coplanar and connected as a whole, forming a flat viewing surface, making the door frame 300 look flat, avoiding the formation of seams or steps on the viewing surface of the door frame, and meeting the customer's appearance requirements.

[0051] Furthermore, given the same surface dimensions, the dimension of the surface of the line contact portion 3037 facing the outside of the house in the direction away from the door opening can be set larger to achieve a larger wall pressing dimension, making it easier to cover gaps and improving the tolerance of the door frame 300 for installation in door openings with non-standard dimensions. Specifically, the dimension of the surface of the line contact portion 3037 facing the outside of the house in the direction away from the door opening can be set equal to the dimension of the surface of the main body 3031 facing the outside of the house in the direction away from the door opening. This equality includes being completely identical or close, and is not specifically limited in this embodiment.

[0052] The main body 3031 is frame-shaped, and a plate thickening portion 3034 is provided inside it. The plate thickening portion 3034 can be used to install hinge fasteners. The hinge 305 (such as a hidden hinge) connecting the door leaf 200 is fixed to the plate thickening portion 3034 through the hinge fasteners (such as fastening screws), making the installation more stable.

[0053] The main body 3031 is provided with an angle code installation slot and / or an angle piece installation slot; the line contact portion 3037 is provided with an angle code installation slot and / or an angle piece installation slot; by inserting the angle code 3038 into the angle code slot and inserting the angle piece 3036 into the angle piece 3036 slot, the stability of the outdoor flat panel line 303 can be enhanced to a certain extent, and the fastening of the door frame 300 can also be facilitated.

[0054] The door frame 300 further includes a door frame magnetic seal 304 , which is fixed to the main body 3031 and / or the door closing limiter 3035 ; the door frame magnetic seal 304 is used to attract the door leaf magnetic strip 202 of the door leaf 200 .

[0055] The door frame 300 provided in this embodiment is equipped with a door frame magnetic seal 304, which cooperates with the door leaf magnetic strip 202 of the door leaf 200 to achieve a better sound insulation and light-proof effect.

[0056] like Figure 1As shown, the indoor flat panel line 301 has a second fixing groove, into which the indoor end of the auxiliary cover stand 302 is inserted and fixed. The outdoor and indoor ends of the auxiliary cover stand 302 are inserted and fixed in the two fixing grooves, respectively, rather than being fixedly connected to the outdoor flat panel line 303 and the indoor flat panel line 301 via a specific connection structure. This ensures that cutting of the auxiliary cover stand 302 does not affect its insertion into the two fixing grooves, improving the convenience of door cover 300 assembly.

[0057] In the above-mentioned door frame 300, the wall-pressing dimensions of the indoor flat panel line 301 and the outdoor flat panel line 303 are the same, so that customers do not need to consider too many reserved dimensions when purchasing furniture near the inward-opening door leaf assembly. One size can meet the needs, which can simplify the decoration process.

[0058] An embodiment of the present invention also provides an inward-opening door leaf assembly, including a door frame 300 and a door leaf 200 connected to the door frame 300 through a hinge 305; the door frame 300 is the door frame 300 provided in the above embodiment; the side wall of the door leaf 200 is a step structure, so as to form a first door gap 2001 on the outdoor side and a second door gap 2002 on the indoor side between the door frame 300, and the first door gap 2001 and the second door gap 2002 are parallel and not on the same straight line.

[0059] The door leaf edge sealing 201 of the door leaf 200 is made of metal, and includes a first fitting portion 2012 and a second fitting portion 2014 for fitting on the side wall of the door leaf. The surfaces of one side of the first fitting portion 2012 and the second fitting portion 2014 that fit on the side wall of the door leaf are not on the same plane. The first fitting portion 2012 and the second fitting portion 2014 are both provided with buckles 2011, which are used to be inserted into the side wall of the door leaf and fixed with the hooks on the side wall of the door leaf; the buckles 2011 can be set to be columnar or plate-shaped.

[0060] A magnetic component mounting groove is provided at the junction of the first fitting portion 2012 and the second fitting portion 2014, and on the side facing away from the side wall of the door leaf, and a door leaf magnetic strip 202 is provided in the magnetic component mounting groove. The door leaf magnetic strip 202 can be a magnet-injected magnet, and one of the side walls of the magnetic component mounting groove is fitted with the door cover magnetic seal 304. The side wall is the suction surface, and the size of the suction surface can be designed to be the maximum size without affecting the installation of other hardware. The elderly or children can use it normally, and it cooperates with the door cover magnetic seal 304 of the door cover 300, thereby effectively improving the sealing and sound insulation effect of the door leaf 200, and can also play a certain supporting role for the door leaf 200 to prevent the door leaf 200 from deformation.

[0061] The door leaf edge seal 201 is used to connect to the door leaf 200. In some embodiments, a glue seam may be left at the connection between the door leaf edge seal 201 and the door leaf 200. The width of the glue seam can be designed to be 0.2 mm. By applying glue into the glue seam, the bonding strength between the door leaf edge seal 201 and the door leaf 200 can be further increased. As the stability of the door leaf edge seal 201 is improved, the installation reliability of the door leaf magnetic strip 202 is also improved.

[0062] In the present invention, the door leaf 200 includes a door leaf magnetic strip 202 and external metal (i.e., the door leaf edge sealing 201). The door leaf magnetic strip 202 is fixed to the door leaf 200 through the external metal with high precision, so that the metal outside the door leaf magnetic strip 202 in the door leaf 200 and the door frame magnetic seal 304 of the door frame 300 are closely matched, thereby improving the sealing effect and waterproof and moisture-proof performance of the door leaf 200, and improving the sound insulation effect. The texture and hardness of the door leaf 200 itself are also improved, and deformation will not occur, meeting the customer's demand for a quiet space in the bedroom. The side walls of the magnetic mounting groove wrap around the internal door leaf magnetic strip 202, protecting the internal door leaf magnetic strip 202 and making it durable. It will not deform or crack after being subjected to long-term impact. The soft door leaf magnetic strip 202 is protected by external metal and can be fixed with strong glue. By precisely designing the thickness of the suction surface, it not only ensures the protection of the door leaf magnetic strip 202, but also does not affect the suction generated by the door leaf 200 and the door leaf magnetic strip 202 when closing. At the same time, it plays a certain supporting role and reduces the abnormal noise of the door leaf 200.

[0063] The present invention can seal the four sides of the door leaf 200 to wrap the sides of the door leaf 200, thereby improving the supporting force of the door leaf 200 itself, enhancing the hardness of the door leaf 200, and preventing deformation. The sturdy door leaf edge sealing 201 protects the four side walls of the door leaf 200 and prevents damage due to bumps. At the same time, it isolates the invasion of moisture and keeps the inside of the door leaf 200 dry, thereby greatly extending the service life of the door leaf 200 and ensuring its own quality. The four-sided door leaf edge sealing 201 makes the sides of the door leaf 200 more refined, increases the overall sense of technology, and has a high aesthetics, meeting customer needs for appearance.

[0064] The side of the door leaf 200 can be provided with a mounting groove to assemble the hardware 203, and the hardware 203 can enhance the strength of the edge of the door leaf 200 and improve the anti-deformation ability of the door leaf 200; in this case, the hook in the side wall of the door leaf for cooperating with the buckle 2011 can be provided on the above-mentioned hardware 203, such as Figure 1 shown.

[0065] See also Figure 5 The hardware 203 installed in the groove on the side of the door leaf 200 close to the ground can fix the silent strip 204 to improve the sealing performance and sound insulation performance of the door leaf 200.

[0066] like Figure 3 As shown, in a specific embodiment of the present invention, the magnetic component installation groove has a closed outer side wall, that is, along the extension direction of the door leaf edge seal 201, the outer side wall of the magnetic component installation groove is closed, which increases the fitting area of the door leaf magnetic strip 202 in the magnetic component installation groove and improves the installation reliability. The door leaf magnetic strip 202 can be bonded in the magnetic component installation groove by glue to prevent the door leaf magnetic strip 202 from moving in the magnetic component installation groove. Of course, the door leaf magnetic strip 202 can also be not bonded, but simply embedded in the magnetic component installation groove. After the magnetic attraction force decreases, the door leaf magnetic strip 202 can be easily replaced.

[0067] At least one end of the magnetic member installation slot has an insertion port for inserting the door leaf magnetic strip 202. When installing the door leaf magnetic strip 202, it can be inserted into the magnetic member installation slot through the insertion port at one end of the magnetic member installation slot and fixed with glue.

[0068] The first fitting portion 2012 and the second fitting portion 2014 are connected by the connecting portion 2013. Specifically, the first fitting portion 2012 and the second fitting portion 2014 are arranged in parallel and perpendicular to the connecting portion. The second fitting portion 2014 is closer to the outdoor surface of the door leaf 200 than the first fitting portion 2012. In this embodiment, the magnetic component mounting groove is provided on the connecting portion 2013 and is close to one side of the second fitting portion 2014, that is, the magnetic component mounting groove is located at the angle between the second fitting portion 2014 and the connecting portion 2013. This allows the door leaf magnetic strip 202 to be located at the notch position of the door leaf 200, thereby having a certain concealing effect on the door leaf magnetic strip 202. After installation, the door leaf magnetic strip 202 and the door cover magnetic seal 304 will not be excessively exposed, especially on the outdoor side, because the door leaf magnetic strip 202 is completely enclosed in the magnetic component mounting groove and is not exposed at all, thereby improving the overall aesthetics of the door leaf 200.

[0069] In this embodiment, the sidewalls of the magnetic component mounting slot include at least the outer wall of the second fitting portion 2014, the outer wall of the connecting portion 2013, and the magnetic sidewall of the door leaf for fitting with the magnetic seal 304 of the door frame (the magnetic sidewall of the door leaf is the suction surface of the magnetic component mounting slot). The magnetic sidewall of the door leaf is arranged at an angle to the second fitting portion 2014. It should be noted that arranging the magnetic sidewall of the door leaf at an angle can increase the area of the suction surface within a limited width. In this embodiment, the magnetic sidewall of the door leaf can form an angle within the range of 40°-50° with the second fitting portion 2014. The gap between the first fitting portion 2012 and the door frame 300 is the second door gap 2002, and the gap between the second fitting portion 2014 and the door frame 300 is the first door gap 2001. The sidewalls of the magnetic component mounting slot may also include an exposed portion corresponding to the first door gap 2001, the exposed portion being perpendicular to the second fitting portion 2014.

[0070] The door closing stop portion 3035 corresponds to the first contact portion 2012. That is, when the door is closed, the side surface 3033 reserved for door closing is closer to the door leaf 200 than the auxiliary sleeve upright 302. Furthermore, the dimension of the side surface 3033 in the thickness direction of the door leaf 200 (when the door is closed and facing downward) is significantly smaller than the dimension of the auxiliary sleeve upright 302 in the thickness direction of the door leaf 200. Because the dimension of the side surface 3033 reserved for door closing is smaller in the thickness direction of the door leaf 200, it has less impact on the space for the door leaf 200 to rotate. Therefore, the gap between the door leaf 200 and the side surface 3033 can be designed to be relatively small. Although the distance between the door leaf 200 and the auxiliary sleeve upright 302 is relatively large, a closing gap is formed between the door leaf 200 and the side surface 3033 when the door is closed. Therefore, a small closing gap is maintained while ensuring that the door leaf 200 can open and close normally.

[0071] The thickness of the magnetic side wall of the door leaf will affect the adsorption force of the magnetic strip 202 of the door leaf. In this embodiment, the thickness of the magnetic side wall of the door leaf can be designed to be 0.2mm-0.4mm, which not only protects the soft magnetic strip 202 of the door leaf, but also does not affect the magnetic attraction between the magnetic strip 202 of the door leaf and the magnetic seal 304 of the door frame.
