Description

Technical Field

[0001] This utility model belongs to the field of alloy door and window manufacturing technology, and in particular relates to a modular combined aluminum alloy window corner connection structure. Background Technology

[0002] Traditional aluminum alloy window corner connection structures often use welding or simple bolt fixing methods, which have problems such as low installation efficiency, insufficient structural stability, and difficulty in adjustment. Especially when horizontal and vertical profiles are joined at right angles, if only welding or ordinary screws are used for connection, the connection is prone to loosening or deformation due to external forces, affecting the overall sealing performance and service life of the window.

[0003] Furthermore, the lack of precise positioning design for connectors in existing technologies makes alignment difficult during assembly, and also makes subsequent maintenance or disassembly challenging. Therefore, there is an urgent need for a corner connection solution that can be installed quickly, ensure structural strength, and is adjustable and detachable. Utility Model Content

[0004] The purpose of this utility model is to provide a modular and combined aluminum alloy window corner connection structure to solve common problems such as low installation efficiency, insufficient structural stability, and difficulty in adjustment of alloy windows.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: it includes a horizontal profile and a vertical profile, the horizontal profile and the vertical profile are joined at a right angle, the inner sides of the horizontal profile and the vertical profile are both fixed with a metal plane for installation, and a plug connector and a plug-in limiting member are provided between the horizontal profile and the vertical profile. The plug connector passes through the plug-in limiting member and is connected to the vertical profile by screws.

[0006] Furthermore, the plug-in connector includes a rigid screw post, one end of which is milled with a threaded hole, and the other end of which is fixedly provided with a circular abutment block. The abutment block is welded to the metal plane on the inner side of the horizontal profile, and the rigid screw post is fixed to the vertical profile by screws and threaded holes.

[0007] Furthermore, a limiting ring is fitted on the outer side of one end of the rigid screw post, and the limiting ring is fixedly connected to the inner wall of the vertical profile.

[0008] Furthermore, the insertion limiting component includes a mounting plate, the bottom of which is provided with a plurality of metal limiting pieces with U-shaped openings on the inner side and fixedly connected, and the mounting plate is welded to the metal plane on the inner side of the vertical profile.

[0009] Furthermore, several of the metal limiting plates are secured to the outside of the rigid screw post, and the sides and bottom surfaces of the metal limiting plates are in contact with the inner wall of the horizontal profile.

[0011] Furthermore, a plurality of annular washers are equidistantly sleeved on the outer side of the rigid screw post, and the annular washers are located between two adjacent metal limiting pieces and their surfaces are in contact with each other.

[0012] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects:

[0013] 1. In this utility model, the modular design is achieved through the cooperation of plug-in connectors and plug-in limiting parts, which enables the horizontal and vertical profiles to be assembled quickly, reducing construction difficulty and improving installation efficiency. The U-shaped opening of the metal limiting piece and the cooperation of the limiting ring ensure the precise alignment of the window frame during installation. The setting of the annular gasket further adjusts the connection gap to adapt to the tolerance requirements of different profiles, ensuring precise positioning while also being adjustable.

[0014] 2. In this utility model, the dual limiting design of rigid screw posts and metal limiting plates effectively disperses the stress at the corners, prevents the profile from deforming or loosening due to external forces, enhances the overall compressive strength and durability of the window, and improves the structural stability of the window frame.

[0021] 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.

[0022] Combination Figures 1 to 4 The modular combined aluminum alloy window corner connection structure shown includes a horizontal profile 1 and a vertical profile 2. The horizontal profile 1 and the vertical profile 2 are joined at a right angle. The inner sides of both the horizontal profile 1 and the vertical profile 2 are fixed with metal planes for installation. A plug-in connector 3 and a plug-in limiting member 4 are provided between the horizontal profile 1 and the vertical profile 2. The plug-in connector 3 passes through the plug-in limiting member 4 and is connected to the vertical profile 2 by screws.

[0023] The plug connector 3 includes a rigid screw post 31. One end of the rigid screw post 31 is milled with a threaded hole, and the other end of the rigid screw post 31 is fixed with a circular abutment block 32. The abutment block 32 is welded to the metal plane inside the horizontal profile 1. The rigid screw post 31 and the vertical profile 2 are fixed by screws and threaded holes.

[0024] A limiting ring 33 is fitted on the outer side of one end of the rigid screw post 31, and the limiting ring 33 is fixedly connected to the inner wall of the vertical profile 2.

[0025] The insertion limiting component 4 includes a mounting plate 41. The bottom of the mounting plate 41 is provided with several metal limiting pieces 42 with U-shaped openings on the inner side, which are fixedly connected. The mounting plate 41 is welded to the metal plane on the inner side of the vertical profile 2.

[0026] Several metal limiting plates 42 are locked on the outside of the rigid screw post 31, and the sides and bottom surfaces of the metal limiting plates 42 are connected to the inner wall of the horizontal profile 1.

[0027] One end surface of both the abutting block 32 and the limiting ring 33 abuts against the metal limiting piece 42.

[0028] A number of annular washers 34 are equidistantly sleeved on the outer side of the rigid screw post 31. The annular washers 34 are located between two adjacent metal limiting pieces 42 and their surfaces are in contact with each other.

[0029] Working principle: When using this utility model, the abutment block 32 at one end of the rigid screw post 31 is welded to the metal plane on the inner side of the horizontal profile 1, so that the rigid screw post 31 is perpendicular to the extension direction of the profile. Then, the limiting ring 33 is welded and fixed to the corresponding position on the inner wall of the vertical profile 2. The mounting plate 41 of the insertion limiting member 4 is welded to the metal plane on the inner side of the vertical profile 2, ensuring that the openings of the multiple metal limiting pieces 42 at its bottom face downward.

[0030] An annular washer 34 is fitted onto the rigid screw post 31. The horizontal profile 1 and the vertical profile 2 are joined at a right angle, allowing the rigid screw post 31 to pass through the U-shaped opening of the metal limiting piece 42. At the same time, the annular washer 34 is inserted between two adjacent metal limiting pieces 42 to eliminate gaps and provide axial support to prevent the metal limiting pieces 42 from bending and collapsing. The limiting ring 33 and the abutment block 32 abut against the surfaces of the metal limiting pieces 42 at both ends to form axial limiting. Finally, the screw passes through the vertical profile 2 and is screwed into the threaded hole of the rigid screw post 31 to complete the fastening.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
