Description

Technical Field

[0001] This utility model relates to the field of door frame technology, and more specifically, to a minimalist narrow aluminum door frame. The utility model name of this utility model can also be "a narrow aluminum door frame". Background Technology

[0002] The door frame is installed inside the doorway, hinged to the door leaf, allowing the door leaf to open or close stably within the doorway. Traditional door frames are made of wood, but wooden frames have poor stability. If the wooden frames are too small, they may not be able to withstand the weight of the door leaf or the pressure from daily opening and closing, resulting in deformation or damage. Wooden frames are also prone to warping if they get damp.

[0003] A prior art Chinese patent application (application number: 201220395609.X, application date: 2012.08.10) discloses a composite door frame, comprising: a left door frame assembly installed on the side wall of the door opening, a right door frame assembly installed on the right side wall of the door opening, and an upper door frame assembly installed on the top wall of the door opening. The left, right, and upper door frame assemblies are all constructed of metal profiles and wood panels. The main door frame component is installed at the outer edge of the door opening, is made of metal profile, and has mutually perpendicular outer door frame grooves and first decorative panel connecting grooves at both ends. The door frame includes a step to stop the door leaf, with a shock-absorbing strip connecting cavity on the step; a door frame sub-component, installed at the inner edge of the door opening, is made of metal profile and has mutually perpendicular inner door frame grooves and second decorative panel connecting grooves; a door frame decorative panel, made of wood, has both ends inserted into the first and second decorative panel connecting grooves respectively; an outer door frame trim, also made of wood, has one end inserted into the outer door frame trim slot and is pasted to the outer wall of the door opening; and an inner door frame trim, also made of wood, has one end inserted into the inner door frame trim slot and is pasted to the inner wall of the door opening. In other words, the existing technology still primarily uses wood panels, connected by metal profiles. This still suffers from size limitations and is prone to deformation. Furthermore, the current method of splicing wood panels with metal profiles can cause cracking at the joints, leading to decreased overall stability of the door frame.

[0004] In view of this, the present invention provides an extremely simple narrow aluminum door frame to break through size limitations, avoid or reduce door frame deformation problems, and improve the overall stability of the door frame. Utility Model Content

[0073] Understandably, the main casing 1, connecting plate assembly 2, secondary casing 3, and door leaf 4 are all made of metal. Metal is moisture-proof and has high strength, ensuring that the door casing is not easily deformed in any size and also preventing or reducing deformation caused by humid environments. The main casing 1 includes three main casing frame edges 5, with adjacent main casing frame edges 5 connected by fixing brackets 6. The secondary casing 3 includes three sequentially connected secondary casing frame edges 25, with adjacent secondary casing frame edges 25 connected by secondary casing auxiliary brackets 26. The brackets are used to splice the main casing 1 and secondary casing 3 and limit the connection position of the brackets. This ensures the stability of the assembled main casing 1 and secondary casing 3 and guarantees a tight joint at the corners, thus ensuring the stability of the door casing formed by the main casing 1 and secondary casing 3 clamping the connecting plate assembly 2. The joints can also better bear the connecting adhesive, which helps the door casing to be better fixed to the door opening. The number of connecting plate assemblies 2 is at least two, and the number of connecting plate assemblies 2 can be selected according to the size of the door opening. The depth to which one connecting plate assembly 2 is inserted into another connecting plate assembly 2, the depth to which one connecting plate assembly 2 is inserted into the main sleeve groove 14, and the depth to which one connecting plate assembly 2 is inserted into the secondary sleeve groove 33 can be adjusted, thereby slightly adjusting the length of the formed door frame in the front-to-back direction Y to match the size of more door openings. Specifically, in order to ensure the stability of the connection between the main sleeve 1, connecting plate assembly 2, and secondary sleeve 3, glue is applied to the connecting plate groove 24, the main sleeve groove 14, and the secondary sleeve groove 33 for auxiliary fixation before the connecting plate assembly 2 is inserted. The fixed corner bracket 6 is used to connect the main sleeve frame 5, mainly for connection and fixation. The auxiliary corner bracket 43 is used to connect the main sleeve frame 5 to help make the surface of the main sleeve 1 flush and stable. The auxiliary corner bracket 43 includes the main auxiliary corner bracket 46 and the secondary auxiliary corner bracket 49. The auxiliary corner bracket 43 further helps make the surface of the main sleeve 1 flush and stable through the two auxiliary corner brackets. Similarly, the secondary sleeve auxiliary corner bracket 26 includes the secondary sleeve main auxiliary corner bracket 38 and the secondary sleeve secondary auxiliary corner bracket 52. The secondary sleeve frame 25 is connected through the two secondary auxiliary corner brackets 26, and helps make the surface of the secondary sleeve 3 flush and stable. The lock stop hole 53 is provided to facilitate the fixing of the lock stop pad to the side of the outer plate 8 of the main sleeve near the inner plate 9 of the main sleeve. The lock stop pad elevates the lock stop 55, so that after installation, the minimum distance between the lock stop 55 and the inner frame of the main sleeve 1 is 0 mm to 0.5 mm along the left-right direction (X-axis). This helps the lock stop 55 to engage with the latch of the door leaf 4 after installation. The hinge hole 54 is provided to facilitate the installation of the hinge pad to the side of the outer plate 8 of the main sleeve near the inner plate 9 of the main sleeve. The hinge pad elevates the hinge 56, so that after installation, the hinge 56 does not exceed the inner plate 9 of the main sleeve frame 5. That is, the minimum distance between the hinge 56 and the inner frame of the main sleeve 1 is 0 mm to 0.5 mm along the left-right direction (X-axis). This helps the door leaf 4 to rotate normally.The door leaf sealing strip 57 enhances the seal between the door leaf 4 and the main sleeve 1, contributing to sound insulation, noise reduction, waterproofing, and moisture resistance. The fixing plate 58, the door leaf sealing strip 57, and the inner plate 9 of the main sleeve define a triangle, improving the stability of the door leaf sealing strip 57 and preventing or reducing deformation or damage caused by the force applied when the door leaf 4 is opened or closed. The connecting plate 20 features a hollow area 59 to reduce weight and facilitate assembly. The multiple spaced grooves 60 on a single connecting plate 20 provide strength while reducing weight, preventing deformation and improving stability. The groove walls of the main sleeve groove 14 and the secondary sleeve groove 33 each have multiple spaced grooves 60, which can accommodate some adhesive when applied internally, increasing the adhesive coverage area and improving the connection stability between the connecting plate 20 and the groove walls.
