Description

Technical Field

[0001] This utility model belongs to the field of building doors and windows, and relates to an aluminum alloy frame door with corner brackets, and more particularly to an environmentally friendly aluminum frame door structure with adjustable corner brackets. Background Technology

[0002] As a core component for separating indoor and outdoor spaces, the design appeal and environmental friendliness of aluminum frame doors have become key factors influencing user decisions. However, existing aluminum frame door products still have significant shortcomings in structural design and manufacturing processes, specifically manifested in an imbalance between aesthetic form and functionality, and deficiencies in the environmental friendliness and reliability of connection structures.

[0003] The visual thinness caused by narrow bezels contrasts sharply with the "substantial quality" sought by high-end commercial spaces and residential users. Furthermore, to maintain rigidity, narrow bezel structures often require increasing wall thickness to over 2.2mm, resulting in material waste.

[0004] Regarding the environmental and reliability deficiencies of the connection structure, the industry mainstream still uses ABS plastic corner brackets (accounting for over 90%) in conjunction with epoxy resin adhesive for fixing.

[0005] In summary, existing aluminum frame doors have a limited and simple design, narrow door panel borders that fail to project a sophisticated image, and the corner brackets, mostly made of plastic and secured with adhesive, are not environmentally friendly. Therefore, it is necessary to improve and innovate the existing aluminum frame door structure. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 11 As shown, an environmentally friendly adjustable angle bracket aluminum frame door structure is provided, including a frame door body 100, several sets of metal adjustable angle brackets 200, metal gaskets 300, adjusting top screws 400 and locking screws 500.

[0034] The frame door body 100 is mainly composed of four sets of shaped frame edges connected end to end and a honeycomb core panel 105 installed in the center. The combination structure of the four sets of shaped frame edges and honeycomb core panel not only strengthens the support of the door body, but also achieves lightweight and environmental protection by using honeycomb core panel 105.

[0035] The metal adjustment brackets 200 and metal pads 300 are in four sets, all in an L-shaped structure, and are respectively embedded and installed at the connection points of the above-mentioned frame shapes. By replacing traditional plastic brackets with metal materials, the pollution problems caused by adhesive fixing are avoided, and the L-shaped structure can adapt to the splicing angle of the frame, improving the installation stability.

[0036] Furthermore, the metal adjusting angle bracket 200 has a metal shim 300 mounted on its front side via several threaded adjusting screws 400, which is used to precisely adjust the position of the metal shim, thereby compensating for splicing errors and ensuring a natural fit at the 45° splicing angle.

[0037] The back of the metal adjustment bracket 200 is fixedly installed on the two adjacent frame shapes with several locking screws 500. The locking screws 500 on the back securely connect the metal adjustment bracket 200 to the adjacent frame shapes by mechanical fixing, so as to avoid loosening due to adjustment.

[0038] This environmentally friendly adjustable corner code aluminum frame door structure improves the environmental performance of aluminum frame doors and enhances the corner code adjustment capability through structural optimization and material improvement. Moreover, the synergistic effect of each component not only solves the problems of traditional aluminum frame doors having a single shape and poor environmental performance, but also improves splicing accuracy and reliability through the adjustable corner code 200.

[0039] In one of the embodiments, such as Figure 1 and Figure 3 As shown, the frame door body 100 consists of a left decorative frame 101, an upper decorative frame 102, a right decorative frame 103, and a lower decorative frame 104, as well as a centrally mounted honeycomb core panel 105. Several sets of metal adjusting brackets 200 and metal shims 300 are used to fix and connect the left, upper, right, and lower decorative frames in their arrangement order, ensuring the installation direction and structural stability of each frame.

[0040] The centrally installed honeycomb core panel 105 further enhances the door's support performance. Adjacent frame panels are joined at a 45° angle, resulting in an overall rectangular or square shape. This not only accommodates the installation requirements of standard door frames but also simplifies the installation and adjustment process of the metal adjustment brackets 200 through their standardized shape, ensuring the regularity of the door structure and thus improving splicing accuracy and aesthetic harmony.

[0041] In addition, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 10 and Figure 11 As shown, a raised structural structure 106 is provided on the outer side of each of the aforementioned frame shapes, which not only strengthens the bending resistance of the frame connection parts, but also creates a visual line enhancement effect through the three-dimensional extended design, forming a classic and luxurious shape.

[0042] Two mounting holes 107 are respectively provided on the connecting part on the back of each of the two ends of the frame. The mounting holes 107 enable the frame to be accurately positioned through the preset holes during splicing, ensuring that the locking screws 400 of the metal adjustment bracket 300 can be accurately aligned, thereby ensuring the stability of the adjustable function.

[0043] Meanwhile, a second chamfer 108 is provided at the top corners of each of the aforementioned frame shapes. Adjacent second chamfers 108 are joined together to form an accommodating space for installing metal anti-collision corner guards 600. The second chamfer 108 not only eliminates the sharp edges produced by traditional right-angle splicing, preventing scratches to the human body during use, but also, through the guiding structure formed by the beveled surface, allows adjacent frames to transition naturally and fit together at a 45-degree angle, solving the problem of unnatural corner splicing.

[0044] In one of the embodiments, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the metal adjusting bracket 200 is a hollow L-shaped metal frame structure. This hollow L-shaped metal frame structure maintains the overall strength of the bracket while reducing material usage and overall weight, thereby improving installation efficiency and reducing resource waste.

[0045] Based on actual application requirements, the front of the metal adjustment bracket 200 is flat. This flat design ensures sufficient contact area when it fits with the metal gasket 300, preventing installation misalignment or loosening due to uneven surfaces.

[0046] Several raised support blocks 201 are provided on the back of the metal adjustment corner bracket 200. On the one hand, the local thickening or reinforcement design improves the compressive strength of the connection between the back of the corner bracket and the frame. On the other hand, it provides a reliable support base for the subsequent adjustment screw 500, ensuring the uniformity of force transmission during the adjustment process and avoiding deformation of the corner bracket or damage to the frame due to local stress concentration.

[0047] like Figure 4 and Figure 5 As shown, the corresponding support block 201 is provided with set screw holes 203 that mate with the adjusting set screw 400. There are two sets of set screw holes 203, arranged symmetrically from left to right. By providing two sets of symmetrical set screw holes 203 on the support block 201, the positioning deviation and uneven force distribution problems when the adjusting set screw 400 mates with the screw holes can be effectively solved.

[0048] Specifically, the set screw hole 203 cooperates with the adjusting set screw 400 to ensure that the adjusting set screw 400 can be accurately embedded in the set screw hole 203 during the adjustment process, avoiding adjustment failure due to screw hole position misalignment. The two sets of symmetrically arranged designs ensure that the adjusting set screw 400 is subjected to balanced force on both sides, preventing structural deformation or loosening caused by stress concentration on one side, thereby improving adjustment accuracy and stability.

[0049] Furthermore, when the support blocks 201 are arranged independently, the overall structural strength of the corner bracket is insufficient. When the adjusting screw 400 applies force, it can easily lead to uneven stress or even deformation of the support blocks 201, affecting the adjustment accuracy and stability of the corner bracket. To address this, inclined connecting plates 202 are used to connect several support blocks 201, and two sets of adjusting screw holes 203 are respectively provided at the connection points on the left and right sides. The geometric characteristics of the inclined connecting plates 202 enhance the deformation resistance between the support blocks 201, allowing the force applied by the adjusting screw 400 to be evenly distributed on adjacent support blocks 201, avoiding local stress concentration.

[0050] To further optimize the functionality of the metal adjustment corner bracket 200, a notch 204 is provided at the top corner of the metal adjustment corner bracket 200 for embedding a metal anti-collision corner protector 600. This design directly addresses the problem that the top corner of the corner bracket is susceptible to collisions. By adding a corner protector, the impact of external forces is buffered, preventing the corner bracket from deforming or being damaged, while also improving the protective performance of the aluminum frame door corners.

[0051] Secondly, the side wall is provided with a slot 205 for installing the connecting strip 601. The assembly process of the connecting strip 601 is simplified by the snap-fit ​​fixing method, which ensures the precise positioning of the connecting strip 601 and the metal adjustment angle code 200, and enhances the connection stability and appearance consistency of the overall structure of the aluminum frame door.

[0052] In some of these embodiments, such as Figure 3 , Figure 8 and Figure 9 As shown, to improve assembly efficiency and avoid friction or scratches between the metal gasket 300 and other components during installation, the metal gasket 300 is an L-shaped metal plate structure with a first chamfer 301 at its apex. The first chamfer 301 at the apex, through a beveled transition design, effectively eliminates sharp edges, reduces frictional resistance during assembly, and avoids scratching the surfaces of adjacent components.

[0053] Furthermore, a plurality of perforated grooves 302 are formed on the metal gasket 300, or at least one end of the metal gasket has a perforated groove 302. The perforated grooves 302 directly reduce the amount of material used in the metal gasket, thereby reducing the overall structural weight and meeting the resource optimization requirements of environmentally friendly design; at the same time, the discontinuous support surface formed by the plurality of perforated grooves 302 can guide stress distribution and avoid deformation problems caused by local stress concentration.

[0054] In some of these embodiments, such as Figure 11 As shown, the shape of the metal adjustment bracket 200 is slightly larger than that of the metal pad 300, so that the metal pad 300 can be precisely pressed against the inside of the bracket by the adjusting screw, avoiding the problem of insufficient installation gap or adjustment margin caused by completely identical size, thereby ensuring the flexibility and stability of splicing angle adjustment.

[0055] Both the metal adjustment bracket 200 and the metal gasket 300 are made of stainless steel or aluminum alloy. Using stainless steel or aluminum alloy avoids the problems of easy aging and low strength of traditional plastic brackets. The high strength and corrosion resistance of metal materials improve the reliability of the overall structure, while meeting environmental protection requirements and reducing the use of adhesives.

[0056] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

[0057] Secondly, the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0058] Finally, the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
