Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a casement door with good sound insulation performance. Background Technology

[0002] A hidden door is a design that blends seamlessly with the wall in terms of visual appearance, creating a more complete and unified wall surface. It is suitable for various design styles. When a hidden door is closed, the shape, size, and style of the exit are not easily discernible.

[0003] In the present technology, hidden doors typically include a door frame fixed to the door opening in the wall and a door body hinged to the door frame. The door body is usually composed of a core panel and decorative panels set on both sides of the core panel. Hidden doors are usually thin and their sound insulation performance usually cannot meet the needs of home use.

[0004] As shown in the existing patent document with announcement number CN220226617U, a hidden door is disclosed, including a door frame assembly for use with a door opening in a wall and a door core assembly that matches the door frame assembly. The door core assembly includes an inner door panel, an outer door panel, and a sound insulation filler disposed between the inner door panel and the outer door panel. The door core assembly also includes a door core profile disposed outside the sound insulation filler and located between the inner door panel and the outer door panel.

[0005] As shown in the aforementioned existing technical documents, although it can enhance sound insulation, it also has the following drawbacks:

[0006] 1. Simply installing a sealing strip on the door frame only creates one seal, resulting in poor sealing and sound insulation performance;

[0007] 2. This structure has very high requirements for the thickness of the sealing strip. In actual use, either the thickness is too thick to close completely, or the thickness is too thin, leaving gaps after closure, resulting in poor sealing and sound insulation.

[0008] 3. Poor applicability of door frame profiles: a door frame profile can only be used for one type of installation. For example, as shown in the patent document above, the second door frame profile 12 can only be used for outward-opening doors and cannot be used for inward-opening doors or outward-opening doors. The inability of door frame profiles to be universally applicable has defects such as high manufacturing costs and large inventory pressure for manufacturers. Utility Model Content

[0009] The purpose of this invention is to provide a swing door with good sound insulation performance, which can at least solve one of the above-mentioned problems.

[0010] According to one aspect of the present invention, a swing door with good sound insulation performance is provided, including a matching door frame assembly and a door leaf assembly, wherein the door frame assembly includes at least a first sealing element and the door leaf assembly includes at least a second sealing element.

[0011] When the door panel assembly is closed relative to the door frame assembly, the door panel assembly abuts against and can compress the first seal, and the door frame assembly abuts against and can compress the second seal.

[0012] In some embodiments, a first right-angle structure is formed on the door frame assembly, and a second right-angle structure is provided on the door leaf assembly to limit and cooperate with the first right-angle structure. The first end of the first seal is installed on the first right-angle structure, and the first end of the second seal is installed on the second right-angle structure.

[0013] In some embodiments, the first seal and the second seal are press-fitted together, and when the door panel assembly is closed relative to the door frame assembly, the second end of the first seal and the second end of the second seal abut against each other and are pressed together to produce deformation.

[0014] In some embodiments, the first seal has a first deformation hole, and the second seal has a second deformation hole.

[0015] In some embodiments, the door frame assembly has a first limiting groove that cooperates with the first sealing element, and the door leaf assembly has a second limiting groove that cooperates with the second sealing element.

[0016] In some embodiments, the door frame assembly includes a first door frame profile, the first door frame profile including a profile body, a first groove opening structure and a second groove opening structure, the first groove opening structure and the second groove opening structure being diagonally disposed at two ends of the profile body, and a first seal being installed on the first door frame profile.

[0017] In some embodiments, the first door frame profile further includes a first protrusion, a first folded edge, a second protrusion, and a second folded edge. The first folded edge extends outward based on the profile body, then folds upward and then inward, forming a first right angle structure between the first folded edge and the profile body. The first protrusion extends vertically upward based on the profile body and together with the first folded edge forms a first groove-shaped opening structure. The second folded edge extends outward based on the profile body and then folds upward. The second protrusion extends vertically upward and downward based on the profile body and together with the second folded edge forms a second groove-shaped opening structure.

[0018] In some embodiments, a break structure is provided on the first protrusion.

[0019] In some embodiments, the door panel assembly includes a door panel profile, an aluminum honeycomb core, a side sealing profile, an inner door panel, and an outer door panel. The door panel profile is disposed at the left and right ends of the aluminum honeycomb core, the inner door panel and the outer door panel are respectively disposed at the front and rear ends of the door panel profile and the aluminum honeycomb core, the side sealing profile is disposed at the outer end of the door panel profile and is matched with the inner door panel and the outer door panel for limiting, and a second sealing member is installed on the side sealing profile.

[0020] In some embodiments, the door frame assembly further includes a second door frame profile, a connecting plate, and a decorative plate. The first end of the decorative plate is installed in a first groove opening structure of the first door frame profile, and the second end extends in a direction away from the door leaf assembly in a manner parallel to the door leaf assembly. The first end of the connecting plate is installed in a second groove opening structure of the first door frame profile, and the second end extends in a direction away from the first door frame profile in a manner perpendicular to the door leaf assembly. The first end of the second door frame profile is fitted onto the second end of the connecting plate, and the second end extends in a direction away from the connecting plate in a manner perpendicular to the connecting plate.

[0021] The beneficial effects of this utility model are:

[0022] 1. This utility model provides a new type of hinged door with good sound insulation performance. The hinged door is equipped with two sealing elements, a first sealing element and a second sealing element. After the door is closed, the door leaf assembly abuts against the first sealing element and can compress the first sealing element, and the first door frame profile abuts against the second sealing element and can compress the second sealing element, thereby forming a double sealing structure, which can significantly improve the overall sealing performance and sound insulation effect of the hinged door when it is closed.

[0023] 2. Through special design, the first and second sealing elements cooperate and squeeze each other, and can contact and squeeze each other after the door is closed to form a third sealing structure, which further improves the overall sealing performance and heat insulation performance.

[0024] 3. The installation position of the seal adopts an inner groove design, which can not only effectively limit the sealing strip, prevent the sealing strip from shifting and extend the service life of the sealing strip, but also cover part of the end of the sealing strip, improving the aesthetics.

[0025] 4. This utility model provides a door frame profile with a novel structure. The door frame profile has two special groove opening structures arranged diagonally on the profile body, which allows for the assembly of different accessories and panels during installation to meet different installation requirements. The door frame profile of this utility model can be used as an outward-opening door, an inward-opening door, an outward-opening door, and an inward-opening door, and can also be used as a hidden door. It has strong applicability, and manufacturers only need to manufacture one type of door frame profile, which greatly reduces manufacturing costs and inventory pressure.

[0026] 5. The second protrusion can be broken off through the breaking structure. The door frame profile in this state can be used as a hidden door frame or an outward-opening and inward-opening door frame, which is convenient to use and easy to operate.

[0027] 6. The door frame profile is equipped with reinforcing ribs, which not only enhance the overall structural strength of the door frame profile, but also cooperate with fasteners such as self-tapping screws used to fix hinges and other hinge components. This effectively increases the contact area between the fasteners and the door frame profile, and in effect increases the number of threads, thereby enhancing the stability of hinges and other hinge components and extending their service life.

[0095] The advantages of this new type of hinged door with good sound insulation performance compared to existing technologies are:

[0096] 1. This utility model provides a new type of hinged door with good sound insulation performance. The hinged door is equipped with two sealing elements, a first sealing element 10 and a second sealing element 20. After the door is closed, the door leaf assembly 2 abuts against the first sealing element 10 and can compress the first sealing element 10, and the first door frame profile 11 abuts against the second sealing element 20 and can compress the second sealing element 20, thereby forming a double sealing structure, which can significantly improve the overall sealing performance and sound insulation effect of the hinged door in the closed state.

[0097] 2. Through special design, the first sealing element 10 and the second sealing element 20 cooperate and squeeze each other, so that they can contact and squeeze each other after the door is closed, forming a third sealing structure, which further improves the overall sealing performance and heat insulation performance.

[0098] 3. The installation position of the seal adopts an inner groove design, which can not only effectively limit the sealing strip, prevent the sealing strip from shifting and extend the service life of the sealing strip, but also cover part of the end of the sealing strip, improving the aesthetics.

[0099] 4. This utility model provides a door frame profile with a novel structure. The door frame profile has two special groove opening structures, one first groove opening structure 112 and the other first groove opening structure 112, which are arranged diagonally on the profile body 111. This allows for the assembly of different accessories and panels during installation to meet different installation requirements. The door frame profile of this utility model can be used as an outward-opening door, an inward-opening door, an outward-opening door, and an inward-opening door. It can also be used as a hidden door. It has strong applicability, and manufacturers only need to manufacture one type of door frame profile, which greatly reduces manufacturing costs and inventory pressure.

[0100] 5. The second protrusion 116 can be broken off by the breaking structure 114a. The door frame profile in this state can be used as a hidden door frame or an outward-opening and inward-opening door frame, which is convenient to use and easy to operate.

[0101] 6. The door frame profile is equipped with reinforcing ribs 111a, which not only strengthens the overall structural strength of the door frame profile, but also allows the reinforcing ribs 111a to cooperate with fasteners such as self-tapping screws used to fix hinges and other hinge components. This effectively increases the contact area between the fasteners and the door frame profile, and in effect increases the number of threads, thereby enhancing the stability of hinges and other hinge components and extending their service life.

[0102] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
