AI Technical Summary
Traditional aluminum alloy door and window profiles are prone to deformation and corner cracking during long-term use. In particular, their structural stability is insufficient under the influence of large-size window frames and environmental factors, and uneven installation methods lead to poor sealing.
The screw is driven by a worm gear drive, which drives the screw block and connecting rod to push the connector to make close contact with the inner wall of the window opening. Combined with the bevel gear meshing screw cylinder and corner support, it forms a rigid support in the lateral and corner. It is also connected to the window frame diagonally by reinforcing ribs to form a diagonal brace structure, which enhances the overall structural stability. At the same time, it is connected to the wall by bolts to form a tensile connection.
It significantly improves the overall structural stability of the window frame, reduces the risk of deformation and cracking, ensures that the doors and windows maintain a stable shape for a long time, and improves the connection strength between the window frame and the wall, solving the deformation and sealing problems of traditional aluminum alloy door and window profiles during use.

Description
Technical Field
[0001] This invention relates to the field of aluminum alloy door and window technology, and in particular to a deformation-resistant aluminum alloy door and window profile. Background Technology
[0002] Aluminum alloy doors and windows are widely used in the building decoration field due to their lightweight, beautiful appearance, and corrosion resistance, becoming one of the mainstream choices for doors and windows in modern homes and commercial buildings. However, during long-term use, traditional aluminum alloy door and window profiles have gradually revealed many deformation problems, seriously affecting their performance and service life.
[0003] From a structural design perspective, traditional aluminum alloy window and door frames are mostly single-frame structures, lacking effective internal support and reinforcement mechanisms. When the window or door size is large, the overall rigidity of the frame is insufficient, and under the long-term action of its own weight, deformation phenomena such as sagging in the middle and bending of the frame are prone to occur. At the same time, under the repeated external force of daily opening and closing of the window sash, or when exposed to environmental factors such as wind pressure and temperature changes (such as thermal expansion of the profile due to high temperatures in summer and contraction due to low temperatures in winter), the structural stability of the window frame further decreases, and the deformation problem becomes more prominent.
[0004] From the perspective of installation and fixing methods, traditional aluminum alloy doors and windows are usually fixed to the wall only by simple connectors on the edge of the frame. The fixing points are relatively scattered and the support is limited. This installation method is difficult to provide comprehensive and uniform support to the window frame, especially at stress concentration points such as the four corners of the window frame. There is a lack of targeted reinforcement structures, and over long-term use, uneven stress can easily lead to deformation and cracking at the corners, which in turn affects the airtightness of the doors and windows, resulting in problems such as air leakage and water seepage.
[0005] Therefore, a type of deformation-resistant aluminum alloy door and window profile is needed to solve the problems mentioned above. Summary of the Invention
[0006] To address the shortcomings of existing technologies, this invention provides a deformation-resistant aluminum alloy door and window profile, solving the problems mentioned in the background section.
[0007] Technical Solution: To solve the above-mentioned technical problems, according to one aspect of the present invention, more specifically, a deformation-resistant aluminum alloy door and window profile, including a window frame, wherein side grooves are formed on the upper and lower surfaces and left and right sides of the window frame, and rotating grooves are symmetrically formed inside the side grooves. A lead screw is rotatably connected inside the side groove, a worm gear is fixed in the middle of the outer surface of the lead screw, a worm is meshed with the outer surface of the worm gear, the front end of the worm extends through to the front surface of the window frame, two screw blocks are threadedly connected to the outer surface of the lead screw, two connecting pieces are slidably connected inside the side groove, and two connecting pieces are rotatably connected inside the connecting pieces. A connecting rod is provided, with the connecting rod closer to the side groove rotatably connected to the inside of the side groove, and the connecting rod further away from the side groove rotatably connected to the inside of the screw block. The end of the connector away from the window frame is fixed with a connecting rod. A cylindrical groove is provided at each of the four corners of the outer surface of the window frame, and a screw cylinder is rotatably connected inside the cylindrical groove. A bevel gear one is fixed on the outer surface of the screw cylinder, and bevel gear two is fixed at both ends of the outer surface of the lead screw. The bevel gear one meshes with two adjacent bevel gear twos. A screw rod is threadedly connected inside the screw cylinder, and an installation part is fixed at the end of the screw rod away from the screw cylinder.
[0008] Furthermore, the front and rear surfaces of the window frame are provided with four rod grooves, and a rotating shaft is rotatably connected inside the front and rear rod grooves. The front and rear ends of the rotating shaft are fixed with reinforcing ribs inside the two rod grooves. The end of the reinforcing rib away from the rotating shaft is provided with a first insertion hole. The front and rear surfaces of the window frame are provided with four card slots, and the end of the reinforcing rib away from the rotating shaft is located inside the card slot. The front and rear card slots are provided with a second insertion hole, and a pin is provided inside the second insertion hole and the two first insertion holes.
[0009] Furthermore, limiting plates are fixed to both the front and rear surfaces of the mounting component, and the opposite sides of the two limiting plates are respectively attached to the front and rear surfaces of the window frame.
[0010] Furthermore, both the front and rear surfaces of the connector are in contact with the inner surface of the side groove.
[0011] Furthermore, a sliding rail is provided on the inner side of the window frame, and two window sashes are slidably connected to the window frame via the sliding rail.
[0012] Furthermore, the surface of the reinforcing rib is coated with an anti-rust coating, the thickness of which is 0.3 mm.
[0013] Furthermore, the worm gear has a hexagonal groove at its front end.
[0014] The beneficial effects of the anti-deformation aluminum alloy door and window profile of the present invention are as follows:
[0015] (1) This invention drives the screw to rotate through a worm gear-worm wheel transmission, which in turn moves the screw block. The connecting rod then pushes the connecting piece and the mounting plate to extend outward and make close contact with the inner wall of the window opening, forming a rigid lateral support for the window frame. At the same time, the bevel gears at both ends of the screw mesh with the bevel gears on the screw barrel, causing the screw barrel to rotate and push the mounting piece to fit against the corner of the window opening, achieving precise support at the corner. The synergistic effect of "lateral support + corner support" makes the window frame bear force evenly and comprehensively, effectively dispersing the stress caused by its own weight, external forces and environmental factors, greatly reducing the risk of deformation such as window frame sagging, bending, and corner cracking, and significantly improving the overall structural stability of the profile.
[0016] After the mounting plate and mounting parts are attached to the inner wall and corner of the window opening respectively, the bolts can be driven into the wall through the mounting holes of the mounting plate. This allows the window frame to not only obtain rigid support through the support structure, but also to form a "tension connection" with the wall, further enhancing the connection strength between the window frame and the wall. This avoids deformation problems caused by loosening of the support during long-term use and ensures that the doors and windows maintain a stable shape for a long time.
[0017] (2) The reinforcing ribs on the front and rear surfaces of the window frame of this invention are rotatably connected to the rod groove via a pivot. In use, the reinforcing ribs can be rotated out and inserted into the groove, and fixed by a pin passing through the insertion hole one and the insertion hole two. The reinforcing ribs obliquely connect the horizontal and vertical frames of the window frame, forming a structure similar to a "brace", which can effectively disperse the lateral and longitudinal external forces on the window frame and reduce the risk of frame deformation. The reinforcement effect is more obvious, especially for the stress concentration problem in the middle of large-sized window frames.
[0018] When the window sash needs to be disassembled for maintenance or replacement, simply pull out the pin, and the reinforcing rib can be rotated and retracted into the groove. This will not hinder the disassembly and assembly of the window sash, and solves the problems of poor flexibility and impact on later maintenance of traditional fixed welded reinforcement structures. It balances the structural reinforcement performance with the convenience of daily use. Attached Figure Description

Two screw blocks 10 are threadedly connected to the outer surface of the lead screw 7. Two connecting pieces 11 are slidably connected inside the side groove 4. Two connecting rods 12 are rotatably connected inside the connecting pieces 11. The connecting rods 12 near the side groove 4 are connected to the inner side of the side groove 4. The connecting rod 12, which is away from the side groove 4, is rotatably connected to the inner side of the screw block 10. The connecting rod 12 is fixed at the end of the connecting piece 11 away from the window frame 1. The four corners of the outer surface of the window frame 1 are provided with cylindrical grooves 14. The screw cylinder 15 is rotatably connected inside the cylindrical groove 14. The outer surface of the screw cylinder 15 is fixed with a bevel gear 16. The two ends of the outer surface of the screw 7 are fixed with bevel gears 17. The bevel gear 16 meshes with the two adjacent bevel gears 17. The screw cylinder 15 is threadedly connected with a screw rod 18. The end of the screw rod 18 away from the screw cylinder 15 is fixed with an installation piece 19.
[0029] Preferably, four rod grooves 22 are provided on both the front and rear surfaces of the window frame 1. A rotating shaft 23 is rotatably connected inside the front and rear rod grooves 22. Reinforcing ribs 24 are fixed inside the front and rear ends of the rotating shaft 23 within the two rod grooves 22. A first insertion hole 25 is provided at the end of the reinforcing rib 24 away from the rotating shaft 23. Four locking grooves 26 are provided on both the front and rear surfaces of the window frame 1. A second insertion hole 27 is provided inside the front and rear locking grooves 26. A pin 6 is provided inside the second insertion hole 27 and the two first insertion holes 25.
[0030] Preferably, the front and rear surfaces of the mounting component 19 are fixed with limiting plates 20, and the opposite sides of the two limiting plates 20 are respectively attached to the front and rear surfaces of the window frame 1.
[0031] Preferably, the front and rear surfaces of the connector 11 are in contact with the inner surface of the side groove 4.
[0032] Preferably, a slide rail 2 is provided on the inner side of the window frame 1, and two window sashes 3 are slidably connected to the window frame 1 via the slide rail 2.
[0033] Preferably, the surface of the reinforcing rib 24 is coated with an anti-rust coating with a thickness of 0.3mm, which can effectively resist rust in humid environments and ensure long-term reinforcement effect.
[0034] Preferably, the front end of the worm gear 9 has a hexagonal groove.
[0035] Working principle: The worm 9 is rotated by the Allen wrench, and the screw 7 and the two bevel gears 17 rotate under the transmission of the worm wheel 8. At this time, the two screw blocks 10 move in opposite directions, and the connecting rod 12 pushes the connecting piece 11 and the mounting plate 13 to move outward, so as to contact the inner wall of the window opening. At the same time, under the transmission of the bevel gears 17 and 16, the screw barrel 15 rotates, and the screw 18 drives the mounting piece 19 to contact the corner inside the window opening. At this time, the window frame 1 is stably placed in the window opening under the support of the mounting piece 19, the screw 18, the mounting plate 13 and other structures.
[0036] After the mounting plate 13 and the mounting component 19 are both attached to the inner wall and corner of the window opening, the bolts are driven into the wall through the mounting holes 21 of the mounting plate 13. This allows the window frame 1 to obtain rigid support in both the horizontal and corner directions through the support structure, and also to form a "tight connection" with the wall through the bolts. This significantly improves the bending and tensile resistance, and avoids the deformation of the profile due to its own weight or external forces during long-term use.
[0037] Furthermore, the reinforcing rib 24 is diagonally connected to the "horizontal frame" and "vertical frame" of the window frame, forming a structure similar to a "diagonal brace". This can disperse the lateral and longitudinal external forces on the window frame and reduce the risk of frame deformation. When it is necessary to disassemble or install the window sash 3, simply pull out the pin 6 and rotate the reinforcing rib 24 to retract it into the rod groove 22, so that it no longer obstructs the disassembly or installation of the window sash 3.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
