Description

Technical Field

[0001] The invention relates to the technical field of door and window structures, and in particular to a glue-injected leveling angle bracket and an aluminum alloy door and window. Background Art

[0002] With the rapid development of the home improvement industry, the industrialization of doors and windows has risen rapidly, and customers' demand for building doors and windows has continued to increase, and the production requirements for doors and windows have become increasingly higher. Waterproof, quick installation, fastening, and flatness are the quality requirements for high-end system doors and windows. For aluminum alloy doors and windows, the strength and sealing of the corners are very important, which determines the splicing strength and waterproofness of the doors and windows, and is directly related to the stability of the doors and windows and the years of use in the later stage.

[0003] In the prior art, the corner fixation of aluminum alloy doors and windows mostly adopts movable corner code splicing, corner code splicing with glue injection and integrated corner code splicing with glue injection. The movable corner code splicing is connected to the aluminum material by spring clips, and then the doors and windows are fixed by tightening the screws. Compared with the glue injection process, it can be disassembled at any time and assembled on the spot. It is more flexible to use and the cost is relatively reasonable. However, the processing requires more holes and waterproofing is difficult. The corner glue injection process is based on the corner injection process, and the effect of stabilizing the 45° splicing angle is achieved by internal and external glue injection. However, there is no track setting for corner glue injection, and the amount and density of glue injection are uncontrollable, or it depends on the air-drying time during the glue injection, which is prone to deformation, profile distortion, and glass fogging. In addition, the corner code in the prior art does not have the function of keeping the profile plane level, resulting in an unstable installation structure. Summary of the invention

[0004] In order to overcome the problems existing in the above-mentioned prior art, the present invention provides a glue injection leveling angle code with controllable glue injection amount and the function of leveling the profile plane.

[0005] The present invention also provides an aluminum alloy door and window with the above-mentioned glue-injected leveling corner brackets provided at the corners.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A glue-injected leveling angle code, characterized in that it includes a first L-shaped aluminum part, a glue guide and a second L-shaped aluminum part, the glue guide is placed between the first L-shaped aluminum part and the second L-shaped aluminum part, the edge of the glue guide and the cavity between the first L-shaped aluminum part and the second L-shaped aluminum part form a glue injection channel; the outer sides of the first L-shaped aluminum part and the second L-shaped aluminum part are provided with a leveling structure and a glue overflow structure.

[0008] The present invention provides a glue guide between two L-shaped aluminum parts with matching shapes. The leveling structure facilitates leveling between the corner bracket and the door and window profile, making the installation more stable. The overflow glue structure is designed to control the glue injection amount, avoid waste, and ensure the product qualification rate.

[0009] Preferably, the size of the glue guide is smaller than that of the first L-shaped aluminum part and the second L-shaped aluminum part. The glue guide is small in size, so that a specific glue injection channel can be designed for the cavity between its edge and the first L-shaped aluminum part and the second L-shaped aluminum part. The specific shape can be customized as needed to avoid unnecessary regional glue injection, save glue usage, and reduce installation costs.

[0010] Preferably, a glue injection port is provided at the bending position of the first L-shaped aluminum part and the second L-shaped aluminum part, and the shapes of the first L-shaped aluminum part and the second L-shaped aluminum part are adapted.

[0011] Preferably, the leveling structure includes a plurality of leveling units, the leveling units include a groove provided on the outside of the first L-shaped aluminum part and the second L-shaped aluminum part and a convex block provided in the groove, the inner side of the convex block is provided with an inclined surface, and the inclined surface forms a trapezoidal notch when the first L-shaped aluminum part and the second L-shaped aluminum part body are buckled. The width of the convex block is 4 mm, 5 mm or 6 mm.

[0012] The inclined surfaces of the protrusions on the first L-shaped aluminum part and the second L-shaped aluminum part are opposite to each other, forming a trapezoidal notch. During the installation process, a variety of installation methods are applicable. The principle of the leveling structure of the present invention in actual use is as follows: (1) Corner connection: The standard thickness of the corner knife is 3mm, 5mm, and 7mm. Assuming that a 7mm thick corner knife is pressed into the trapezoidal notch of this corner code, the trapezoidal notch is larger at the top and smaller at the bottom, so that the product is stretched open. After the product is stretched open, it supports the inside of the door and window profile, thereby achieving leveling; if a corner knife with a specification of 3mm or 5mm is used, it is only necessary to change the angle of the product bevel to achieve the above function. (2) Screw connection: The screw is a customized size. When the screw is screwed into the product, the tail of the screw contacts the trapezoidal surface of this product. The screw is pressed in to stretch the product. The product is stretched open and supports the inside of the door and window profile, thereby achieving leveling.

[0013] Preferably, a mounting hole connected to the glue injection channel is provided at the trapezoidal notch, a mounting part is provided in the mounting hole, a plurality of glue overflow grooves are provided at the end of the mounting part, a glue overflow port is formed in the cavity between the glue overflow groove and the inclined surface, the glue overflow port is connected to the glue injection channel through the mounting hole, and the glue overflow port, the mounting hole and the glue injection channel constitute a glue overflow structure.

[0014] When the glue injection is completed, the excess glue overflows from the glue injection channel through the mounting hole and the glue overflow port to inform the user to stop the glue injection, so that the glue injection amount can be controlled, avoiding waste while ensuring the product qualification rate.

[0015] Preferably, the inner and / or outer surfaces of the first L-shaped aluminum part and the second L-shaped aluminum part are provided with corrugated or stepped structures, which can increase the friction between the corner bracket and the door and window profiles, and increase the contact area between the glue and the door and window profiles, thereby improving stability.

[0016] Preferably, it also includes a weight-reducing through hole, which passes through the first L-shaped aluminum part, the rubber guide and the second L-shaped aluminum part. The weight-reducing through hole reduces the dead weight of the angle bracket, making it lighter.

[0017] An aluminum alloy door and window comprising any of the above-mentioned glue injection leveling corner brackets, wherein the glue injection leveling corner bracket is arranged at the corner of the aluminum alloy door and window. The aluminum alloy door and window using the glue injection leveling corner bracket has a stable structure, is easy to install, and has a controllable amount of glue injection, thereby avoiding waste and ensuring the product qualification rate.

[0018] Therefore, the present invention has the following beneficial effects:

[0019] (1) Design a specific glue injection channel through the glue guide to avoid unnecessary glue injection in the area, save glue usage, and reduce installation costs;

[0020] (2) The leveling structure facilitates leveling between the corner bracket and the door and window profiles, making the installation more stable;

DETAILED DESCRIPTION

[0036] The technical solution of the present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0037] In the present invention, unless otherwise specified, all equipment and raw materials can be purchased from the market or are commonly used in the industry. The methods in the following embodiments, unless otherwise specified, are conventional methods in the art.

[0038] Example 1

[0039] like Figures 1 to 3 As shown, a glue injection leveling angle code comprises a first L-shaped aluminum part 1, a glue guide 2 and a second L-shaped aluminum part 3, wherein the glue guide is placed between the first L-shaped aluminum part and the second L-shaped aluminum part, the size of the glue guide is smaller than the first L-shaped aluminum part and the second L-shaped aluminum part, and the edge of the glue guide and the cavity between the first L-shaped aluminum part and the second L-shaped aluminum part form a glue injection channel; a glue injection port 12 is provided at the bending part of the first L-shaped aluminum part and the second L-shaped aluminum part, a groove 4 is provided on the outer side of each arm of the L-shaped aluminum part, a convex block 5 with a bevel 6 is provided in the groove, and the width of the convex block is 4 / 5 / 6 mm (such as Figure 2 The inner surfaces of the first L-shaped aluminum member and the second L-shaped aluminum member are provided with a corrugated structure 10, and the two arms are provided with a weight-reducing through hole 11 penetrating the first L-shaped aluminum member, the rubber guide and the second L-shaped aluminum member.

[0040] like Figure 4 and Figure 5As shown, the inclined surface forms a trapezoidal notch 7 when the first L-shaped aluminum part and the second L-shaped aluminum part body are buckled together, and the mounting hole 8 in the trapezoidal notch is as shown in FIG. Figure 4 As shown, a mounting member 14 with four overflow grooves 15 at the end is provided in the mounting hole (see Figure 6 ), the cavity between the overflowing groove and the inclined surface forms an overflowing opening 9, and the overflowing opening is connected to the glue injection channel (not shown in the figure) through the mounting hole. The overflowing opening, the mounting hole and the glue injection channel constitute an overflowing structure.

[0041] The leveling principle of this embodiment is: a mounting piece 14 of customized size is used, and when the product is introduced, the tail of the mounting piece contacts the trapezoidal notch 7 of the glue-injected leveling angle code product. As the mounting piece is screwed in, the glue-injected leveling angle code product generates pressure and is stretched open, supporting the inside of the door and window profile to achieve a leveling effect.

[0042] The installation principle of this embodiment is:

[0043] The first L-shaped aluminum part 1, the rubber guide 2 and the second L-shaped aluminum part 3 are clamped and fixed, and the rubber guide 2 is placed between the first L-shaped aluminum part and the second L-shaped aluminum part. The edge of the rubber guide and the cavity between the first L-shaped aluminum part and the second L-shaped aluminum part form a glue injection channel. Fig.10 As shown, it is a schematic diagram of the partial structure of the aluminum alloy door and window installed with the glue-injected leveling angle code 21, in which the mounting part 19 with four glue overflow grooves 15 is sequentially passed through the reserved mounting holes 19 opened in the door and window profile 18 and the mounting holes of the angle code and tightened to complete the assembly.

[0044] The principle of controlling the glue injection in this embodiment is as follows: after the door and window profiles are connected by the above-mentioned angle brackets, the glue injection holes 20 ( Fig.10 ) and the glue injection hole 12 of the corner code, the glue flows along the glue injection channel, when the glue fills the glue injection channel, the excess glue flows out from the overflow port, informing the user to stop the glue injection, so as to achieve the controllable amount of glue injection and ensure the qualified rate of the product. The cross-sectional view of the glue injection parallel to the corner code after the glue injection is completed after assembly with the door and window profile is as follows Fig.11 As shown, the shaded part is a glue channel 22 filled with glue. The corrugated structure 10 can increase the friction between the corner code and the door and window profiles on the one hand, and increase the contact area between the glue and the door and window profiles on the other hand, thereby improving stability. It can be clearly seen from the figure that the glue overflow groove 15 of the mounting part 14 and the cavity between the inclined surface form a glue overflow port, and the glue overflow port, the mounting hole, and the glue injection channel constitute a glue overflow structure.

[0045] Example 2

[0046] like Figure 7 As shown, the difference between Example 2 and Example 1 is that two flat structures 16 are respectively provided on the outer sides of the two arms of the L-shaped aluminum part, and the width of the protrusions is 4 / 5 / 6 mm, and the rest of the structures are exactly the same.

[0047] The leveling principle of this embodiment is: a standard 7mm thickness corner knife is used to press into the trapezoidal notch of the glue injection leveling corner code. The trapezoidal notch is larger at the top and smaller at the bottom, so that the convex block of the glue injection leveling corner code product is stretched open to support the inside of the door and window profile, thereby achieving the leveling effect. If a corner knife with a specification of 3mm or 5mm is used, the above function can be achieved by simply changing the product bevel angle.

[0048] Example 3

[0049] like Figure 8 and Fig. 9 As shown, the difference between Example 3 and Example 1 is that the inner and outer surfaces of the first L-shaped aluminum part and the second L-shaped aluminum part are provided with step structures 17, the width of the protrusion is 4 / 5 / 6 mm, and the rest of the structure is exactly the same.

[0050] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. There are other variations and modifications without exceeding the technical solutions described in the claims.
