Description

Technical Field

[0001] The utility model relates to the field of aluminum alloy window pulleys, in particular to an aluminum alloy window with a pulley that is convenient for replacing. Background Art

[0002] Aluminum alloy windows with easy pulley replacement are a special window design. Its characteristics are that it uses aluminum alloy as the material and has a specially designed mechanism for easy pulley replacement. The design of easy pulley replacement means that the pulley part of the window adopts a modular or standardized design, so that users or maintenance personnel can easily remove and replace the pulley. The advantage of this design is that when the pulley is damaged or worn, there is no need to replace the entire window, only the pulley needs to be replaced, which reduces the maintenance cost and difficulty.

[0003] A Chinese patent with publication number CN218953144U discloses an aluminum alloy window that is easy to replace a pulley, including an inclined rod, a block rotatably connected to the inclined rod, a vertical frame fixedly connected to a shell, a rotating rod rotatably connected to the vertical frame, a bevel gear b installed on the rotating rod, and a rack meshingly connected to the bevel gear b. When installing the pulley, the block connected to the inclined rod can be driven to move inward into the shell and separate from the frame by rotating the turntable in the opposite direction with a screwdriver. After separation, the shell can be pulled outward to move the shell out of the frame, and a new shell can be inserted into the frame for fixing. The pulley can be replaced by rotating the turntable to drive the block to move inward and outward and separate or buckle with the frame. There is no need to disassemble the aluminum alloy window, and replacement is convenient.

[0004] The above patent facilitates the replacement of the aluminum alloy window pulley. When replacing the pulley, the corresponding pulley needs to have its transmission structure adjusted separately, and the adjustment structure is relatively complicated, requiring the coordination of multiple gears and threaded rods internally. The pulley may encounter particle intrusion and high temperature exposure during actual use. The blockage of particles and the expansion of the material due to high temperature will affect the disassembly effect, making it difficult and inconvenient to replace the pulley.

[0020] In order to solve the problem that when replacing the existing aluminum alloy window with easy pulley replacement, the corresponding pulley needs to be adjusted separately when replacing, and the adjustment structure is relatively complicated, and it can only be achieved through the cooperation of multiple gears and threaded rods inside. The pulley will encounter particle intrusion and high temperature exposure during actual use. The blockage of particles and the expansion of the material caused by high temperature will affect the disassembly effect, making it difficult and inconvenient to replace the pulley. This embodiment provides the following technical solutions:

[0021] An aluminum alloy window for convenient pulley replacement comprises a shell 1 and a glass 2, wherein the glass 2 is located inside the shell 1, and a mounting cavity 3 is arranged at the lower end of the glass 2, and the mounting cavity 3 is recessed at the lower end of the shell 1. Figure 1 As shown, rollers 13 for moving the glass 2 are arranged on both sides of the installation cavity 3, and installation frames 7 are arranged outside the two rollers 13, and the inside of the installation frame 7 is rotatably connected to the center of the roller 13. The roller 13 can be fixed by fixing the installation frame 7 in the installation cavity 3;

[0022] In this embodiment, the two mounting frames 7 are provided with mounting pieces 15 on one side facing the housing 1. The mounting pieces 15 are fitted to the inside of the mounting cavity 3. Figure 2 As shown, a threaded rod 5 is provided in the middle position inside the installation cavity 3, and the threaded rod 5 penetrates and extends to one end of the installation piece 15. The outside of the threaded rod 5 cooperates with the internal thread of the installation piece 15, and one end of the threaded rod 5 is rotatably connected to the housing 1. The threaded rod 5 can generate relative movement with the installation piece 15 through rotation. The installation piece 15 can be converted from rotational movement to longitudinal linear movement after being restricted by the installation cavity 3. The longitudinal linear movement of the installation piece 15 can drive the two connected rollers 13 to extend out of the installation cavity 3 and realize replacement;

[0023] In this embodiment, limiting rods 4 are provided on both sides of the threaded rod 5, and the limiting rods 4 are welded and fixed to the housing 1. Figure 2 As shown, the limiting rod 4 penetrates and extends to both ends of the mounting plate 15, and the outside of the limiting rod 4 is slidably connected to both sides of the inside of the mounting plate 15. The limiting and supporting of the limiting rod 4 can improve the stability of the threaded rod 5 during rotation and the stability of the roller 13 during use, thereby preventing the mounting plate 15 from shaking or loosening during actual use.

[0024] In this embodiment, if Figure 2 and Figure 3As shown, the two mounting frames 7 are respectively provided with support plates 6 on one side of the limiting rods 4 on both sides, and the support plates 6 are welded and fixed to the mounting plates 15. The front and rear ends of the two supporting plates 6 are provided with fixing plates 9, and the fixing plates 9 are welded and fixed to the mounting frames 7. When assembling the mounting frames 7, the two fixing plates 9 on one side of the mounting frames 7 are clamped on both sides of the outside of the supporting plates 6 to facilitate the subsequent penetration of the bolts 10. The support plates 6 and the two fixing plates 9 are penetrated by the bolts 10, and the outside of the bolts 10 cooperates with the internal threads of the support plates 6 and the fixing plates 9. The penetration of the bolts 10 and the clamping of the two fixing plates 9 on the supporting plates 6 can improve the stability of the installation of the mounting frame 7, and prevent the mounting frame 7 from loosening and shaking during daily use.

[0025] In this embodiment, a gasket 14 is welded on one side of the mounting frame 7 facing the mounting plate 15, a limiting ring 8 for limiting and supporting is disposed outside the gasket 14, and the limiting ring 8 is welded and fixed to the mounting plate 15. Figure 3 As shown, during the installation of the installation frame 7, the fixing sheet 9 fits the support plate 6 and drives the gasket 14 to be inserted into the outside of the limiting ring 8, thereby improving the stability of the installation frame 7 during installation and preventing the position of the installation frame 7 from being offset;

[0026] In this embodiment, if Figure 4 As shown, the direction of the bolt 10 and the exposed direction of the installation cavity 3 are perpendicular, and the exposed position of the installation cavity 3 is not parallel to the rotation position of the bolt 10, which can avoid accidental contact with the bolt 10 during daily use, avoid accidental contact causing the position of the installation frame 7 to loosen, and improve the stability of the installation frame 7 when used after installation;

[0027] In this embodiment, guide bars 16 are provided on both sides of the front and rear ends of the installation cavity 3, and the guide bars 16 are welded and fixed to the housing 1. Figure 1 , Figure 2 and Figure 3 As shown, a first recessed adapting groove 11 is provided on both sides of the front and rear ends of the interior of the mounting piece 15, and a second recessed adapting groove 12 is provided on the front and rear ends of the interior of the mounting frame 7, and the outsides of the second adapting groove 12 and the first adapting groove 11 are connected to the external sliding slot of the guide bar 16. The restriction of the mounting piece 15 and the mounting frame 7 by the guide bar 16 can facilitate the adjustment of the position of the mounting frame 7 and the mounting piece 15 and improve the stability during use.

[0028] Working principle: when using the aluminum alloy window and replacing the internal mounting frame 7 and roller 13, rotate the threaded rod 5 clockwise, and after being restricted by the limiting rods 4 on both sides, the mounting plate 15 can be driven to move toward the outside of the mounting cavity 3, and the bolt 10 position will be exposed while moving. After rotating and removing the bolt 10, the mounting frame 7 can be taken out along the guide bar 16, and the roller 13 can be taken out at the same time when the mounting frame 7 is taken out. When replacing the roller 13 after taking it out, insert the replaced roller 13 between the two guide bars 16 through the external mounting frame 7. After the two guide bars 16 slide to the position of the second adapter groove 12 inside the mounting frame 7, the mounting frame 7 will be attached to the two sides of the outside of the support plate 6 through the fixing plate 9, and the mounting frame 7 will be inserted into the limiting ring 8 through the gasket 14. Finally, the fixing of the mounting frame 7 is completed by passing the bolt 10 through the fixing plate 9 and the support plate 6 in turn. Rotating counterclockwise can make the mounting plate 15 inserted into the mounting cavity 3 after the guide bar 16 and the limiting rod 4 are guided, and the replacement of the roller 13 and the mounting frame 7 is completed.
