Description

Technical Field

[0001] This utility model relates to a modular aluminum alloy window frame, and more particularly to a novel connecting mechanism for modular aluminum alloy window frame bodies. Background Technology

[0002] Window frames are structures installed along the edges of window openings. Common materials include wood, aluminum alloy, and stainless steel. Compared to wood, aluminum alloy offers higher strength and durability, is more aesthetically pleasing, practical, and easier to maintain. Compared to stainless steel, aluminum alloy is less expensive and offers greater design flexibility.

[0003] Aluminum alloy window frames are generally composed of multiple vertical and horizontal profiles. To allow for the installation of sliding doors and windows within the frame, guide rails are typically installed on the horizontal profiles, and raised strips are added to the vertical profiles to improve sealing. While aluminum alloy window frames offer many advantages, they also present some challenges. Due to the relatively thin thickness of the aluminum alloy profiles, it is difficult to achieve secure connections using threads or welding. Therefore, achieving a stable, efficient, and relatively cost-effective connection between the profiles in aluminum alloy window frames has become a pressing issue requiring improvement in this field. Summary of the Invention

[0004] This utility model provides a novel connection mechanism for a combined aluminum alloy window frame, solving the problem in the prior art that it is difficult to achieve a fixed connection of aluminum alloy profiles by means of threads or welding.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a novel combined aluminum alloy window frame connection mechanism, including horizontal profiles and vertical profiles. The horizontal profile includes a horizontal square tube, two horizontal baffles and several guide rails. The vertical profile includes a vertical square tube, two vertical baffles and several protruding strips. The width of the horizontal profile is adapted to the distance between the two vertical baffles. It also includes a connecting code. The connecting code consists of a code base, two tensioning blocks, an abutment block and a pull rod. The upper and lower outer side walls of the code base are provided with two mirror-shaped guide slopes. The two tensioning blocks are slidably disposed on the two guide slopes respectively. The abutment block abuts against the rear ends of the two tensioning blocks simultaneously. The pull rod passes through the code base and the abutment block. One end of the pull rod is fixed with a limit cap, and the other end is screwed with a nut. The connecting code is inserted into the end of the horizontal square tube. The two tensioning blocks abut against the inner wall of the horizontal square tube. The horizontal baffles and guide rails at both ends of the horizontal profile are cut off.

[0006] When the end of the horizontal profile abuts against the inner wall of the vertical square tube, the abutting part on the vertical profile is designed with a cut-out protrusion. At the same time, at least two sets of left and right through positioning holes are opened on the inner and outer walls of the vertical square tube in the abutting area. The bracket is provided with a corresponding riveting hole, and a rivet is connected through the riveting hole and the positioning hole.

[0007] When the end of the horizontal profile abuts against the outer wall of the vertical square tube, the abutting part of the vertical profile is designed with a cut-out protrusion and a square hole on the inner wall of the vertical square tube. At the same time, at least two through-hole positioning holes are opened on the outer wall of the vertical square tube in the abutting area. The bracket is provided with a corresponding riveting hole, and a rivet is connected through the riveting hole and the positioning hole.

[0008] The connecting code in this invention has the effect of fine adjustment of external dimensions. By rotating the pull rod or nut, the distance between the limiting cap and the nut is changed, thereby adjusting the position of the abutment block. The change in the position of the abutment block can change the relative position of the tensioning block and the guide slope, thereby increasing or decreasing the distance between the two tensioning blocks. The connecting code can be inserted into the end of the horizontal profile. When the distance between the two tensioning blocks increases, it can abut against the two inner walls of the horizontal square tube, so that the connecting code can be firmly fixed to the horizontal profile. Then, the riveting hole on the connecting code is aligned with the positioning hole on the vertical square tube, and the connecting code is riveted to the vertical square tube to achieve fixation.

[0009] There are two ways to connect horizontal and vertical profiles. One is to have the end of the horizontal profile abut against the inner wall of the vertical square tube, and the other is to have the end of the horizontal profile penetrate the inner wall of the vertical square tube and then abut against the outer wall. Each method has its advantages and disadvantages. The former simplifies the machining of the vertical profile, improving assembly efficiency and reducing production costs. However, the corresponding rivets need to penetrate both sides of the vertical square tube, which is a thin-walled structure and easily deforms under stress, leading to gaps in the riveting. The latter method results in better stress distribution and a stronger connection, but requires more machining, reducing assembly efficiency and increasing production costs.

[0010] Furthermore, when the end of the horizontal profile abuts against the inner wall of the vertical square tube, the diameter of the positioning hole on the inner wall of the vertical square tube is larger than the diameter of the positioning hole on the outer wall. This design takes into account the issue of drilling accuracy, avoiding misalignment between the positioning hole and the riveting hole due to drilling accuracy issues.

[0011] Therefore, this utility model has the following characteristics compared with the prior art: 1. This utility model uses connecting codes to fix horizontal and vertical profiles, which makes the connection firm, reliable and relatively efficient, and the appearance after connection is also more beautiful.

[0022] Example 1: See Figure 1 and Figure 8 A novel connecting mechanism for a combined aluminum alloy window frame includes a horizontal profile 100 and a vertical profile 200, see [link / details]. Figure 2 The transverse profile includes a transverse square tube 110, two transverse baffles 120, and two guide rails 130, see Figure 3 The vertical profile includes a vertical square tube 210, two vertical baffles 220, and two protruding strips 230. The width of the horizontal profile is adapted to the spacing between the two vertical baffles. It also includes a connecting bracket 300. See Figure 5 and Figure 6The connecting code consists of a code base 310, two tensioning blocks 320, an abutment block 330, and a pull rod 340. Two mirror-shaped guide ramps 350 are provided on the upper and lower outer side walls of the code base. The two tensioning blocks are slidably positioned on the two guide ramps, and the abutment block simultaneously abuts against the rear ends of the two tensioning blocks. The pull rod passes through the code base and the abutment block. One end of the pull rod is fixed with a limit cap 341, specifically an internal hexagonal nut, and the other end is screwed with a nut 342. The code base has a cylindrical front receiving cavity 311 for accommodating the limit cap, and the abutment block has a hexagonal prism-shaped rear receiving cavity 331 for accommodating the nut (see...). Figure 7 The connecting bracket is inserted into the end of the horizontal square tube, and the two tensioning blocks abut against the inner wall of the horizontal square tube; the horizontal baffles and guide rails at both ends of the horizontal profile are cut off; the end of the horizontal profile abuts against the inner wall of the vertical square tube, and the abutting part on the vertical profile is designed with a cut-off protrusion. At the same time, two sets of left-right through positioning holes 211 are opened on the inner and outer walls of the vertical square tube in the abutting area. The diameter of the positioning hole on the inner wall of the vertical square tube is larger than the diameter of the positioning hole on the outer wall (see...). Figure 4 The base is provided with a corresponding riveting hole 312, and a rivet 313 is connected through the riveting hole and the positioning hole.

[0023] In this embodiment, the connecting code has the effect of fine-tuning its external dimensions. By rotating the pull rod or nut, the distance between the limiting cap and the nut changes, thereby adjusting the position of the abutment block. Changing the position of the abutment block can change the relative position of the tensioning block and the guide slope, thus increasing or decreasing the distance between the two tensioning blocks. The connecting code can be inserted into the end of the horizontal profile. When the distance between the two tensioning blocks increases, it can abut against the two inner walls of the horizontal square tube, thus securing the connecting code to the horizontal profile. Then, the riveting holes on the connecting code are aligned with the positioning holes on the vertical square tube, and the connecting code is riveted to the vertical square tube for fixation.

[0024] The bracket, two tensioning blocks, and abutment blocks are all made of engineering plastics. While ensuring strength, this helps to increase the coefficient of friction between the connecting bracket and the profile, thereby achieving a firm fixation and significantly reducing production costs.

[0025] For details, see Figure 5 Both guide inclined surfaces are provided with sliding grooves 351, and the tensioning block is provided with guide blocks 321 that slide in cooperation with the sliding grooves.

[0026] For details, see Figure 7 The two ends of the abutment block are also slidably engaged in the two grooves.

[0027] This invention can be modified in many ways, as will be apparent to those skilled in the art, and such modifications are not considered to depart from the scope of this invention. All such modifications that are obvious to those skilled in the art are included within the scope of these claims.
