[0002] Aluminum alloy doors and windows are doors and windows with frames and sash structures made of aluminum alloy building profiles. They are beautiful, airtight, and high in strength, and are widely used in the field of construction projects. In home decoration, aluminum alloy doors and windows are commonly used to enclose balconies. The surface of the aluminum alloy is shiny after oxidation. The sash frames are large and can be inlaid with large areas of glass, allowing sufficient indoor light, enhancing the contrast between the virtual and real surfaces between the interior and exterior, making the living room more hierarchical. Aluminum alloy itself is easy to extrude, the cross-sectional dimensions of the profiles are precise, and the processing accuracy is high. Therefore, many homeowners choose to use aluminum alloy doors and windows in decoration.

[0003] Most of the existing aluminum alloy doors and windows still adopt the left-right push-and-slide opening method, and only use semi-circular ring inserts for locking. Moreover, traditional aluminum alloy doors and windows do not have the function of timely alarm, and their anti-theft function is poor. In order to prevent theft, users often install anti-theft fences or anti-theft nets on the outer wall, which not only affects the external aesthetics but also increases costs. Therefore, to solve the above problems, this application provides an anti-theft aluminum alloy door and window. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following is a further detailed description of the present application in conjunction with the attached Figure 1 - Figure 4 drawings.

[0018] Embodiment 1

[0019] Please refer to Figures 1 - 4 , the present utility model provides a technical solution for an anti-theft aluminum alloy door and window: an anti-theft aluminum alloy door and window, including an aluminum alloy door and window frame 1. Limiting grooves 10 are respectively opened on both inner sides of the aluminum alloy door and window frame 1. Cavities 14 are respectively opened on one side of the aluminum alloy door and window frame 1 corresponding to the limiting grooves 10. One side of the inner part of each limiting groove 10 is rotatably connected with a threaded rod 11. Among them, the threaded rod 11 is installed inside the limiting groove 10, so that the threaded rod 11 can rotate inside the limiting groove 10. The spiral angle of the outer wall of the threaded rod 11 is set to 20 degrees, and the threaded rod 11 extends into the cavity 14. One side of each threaded rod 11 is fixedly connected with a first bevel gear 15. A second bevel gear 16 is rotatably connected on one side of the cavity 14 corresponding to the first bevel gear 15. The first bevel gear 15 and the second bevel gear 16 are closely meshed with each other. Since the cavity 14 and the limiting groove 10 are not communicated with each other, one end of the threaded rod 11 extends into the cavity 14. By connecting one end of the threaded rod 11 with the first bevel gear 15, and the first bevel gear 15 and the second bevel gear 16 are closely meshed with each other, the rotation of the second bevel gear 16 drives the first bevel gear 15 to rotate, so as to drive the threaded rod 11 to rotate forward and backward inside the limiting groove 10. One side of the outer wall of the threaded rod 11 is threadedly connected with a lifting plate 13. By threadedly connecting the threaded rod 11 with the lifting plate 13, and the thread lift of the threaded rod 11 is less than the equivalent friction angle of the screw pair composed of the threaded rod 11 and the lifting plate 13, self-locking is formed to prevent movement caused by external reasons. Then, the size of the lifting plate 13 fits the size of the limiting groove 10, so that by driving the threaded rod 11 to rotate, the lifting plate 13 is driven to lift along the inner wall of the limiting groove 10. One side of the upper surface of the lifting plate 13 is fixedly connected with an insertion rod 17. By connecting the lifting plate 13 with the insertion rod 17, the insertion rod 17 is driven to lift, achieving the effect of facilitating the adjustment of the position of the insertion rod 17.

[0020] Furthermore, a plurality of sliding plates 3 are respectively fixedly connected to both inner walls of the aluminum alloy door and window frame 1. Two window sashes 4 are slidably connected to both inner sides of the aluminum alloy door and window frame 1 through a plurality of sliding plates 3. Plug blocks 8 are respectively fixedly connected to the opposite sides of the two window sashes 4. By installing the window sashes 4 inside the aluminum alloy door and window frame 1 through a plurality of sliding plates 3, the window sashes 4 can be pulled to move along the sliding plates 3.

[0021] Furthermore, slots 12 are provided on the inner side of the aluminum alloy door and window frame 1 corresponding to one side of the insertion blocks 8, and insertion holes 9 are provided on the lower surface of the insertion blocks 8 corresponding to one side of the insertion rods 17. The outer surface of the aluminum alloy door and window frame 1 is rotatably connected with two knobs 2 through two second bevel gears 16. The window sash 4 is connected to the insertion blocks 8. The size of the slots 12 provided on the inner wall of the aluminum alloy door and window frame 1 fits the size of the insertion blocks 8. When the window sash 4 is closed, the insertion blocks 8 are driven to insert into the slots 12. Among them, the slots 12 communicate with the limiting slots 10. By connecting the knobs 2 with the second bevel gears 16, then rotating the knobs 2 drives the second bevel gears 16 to rotate, which drives the first bevel gears 15 to rotate, thereby driving the threaded rod 11 to rotate inside the limiting slots 10, driving the lifting plate 13 to lift along the inner wall of the limiting slots 10, so that the insertion rods 17 at the top of the lifting plate 13 move upward and insert into the insertion holes 9 provided at the bottom of the insertion blocks 8, so as to fix the insertion blocks 8, facilitating the fixation of the window sash 4. By repeating the operation, the two window sashes 4 are fixed, so that the window sashes 4 cannot be pulled open from the outside by people, achieving the effect of improving the anti-theft performance and safety of the aluminum alloy doors and windows.

[0022] Embodiment 2

[0023] Please refer to Figures 1 - 4 , and on the basis of Embodiment 1, it is further obtained that:

[0024] Furthermore, a pyroelectric infrared sensor 6 is fixedly connected to one side of the outer surface of the aluminum alloy door and window frame 1. Among them, the pyroelectric infrared sensor 6 is externally connected to a power supply and a control switch during use, and it is an existing mature technology, which will not be elaborated here. It can monitor people approaching the window sash 4 in real time at night. An alarm 7 is fixedly connected to one side of the outer surface of the aluminum alloy door and window frame 1. Among them, the alarm 7 is externally connected to a power supply and a control switch during use, and it is an existing mature technology, which will not be elaborated here.

[0025] Furthermore, a controller 5 is fixedly connected to one side of the outer surface of the aluminum alloy door and window frame 1. The controller 5 is electrically connected to the pyroelectric infrared sensor 6, and the controller 5 is electrically connected to the alarm 7. By electrically connecting the controller 5 with the pyroelectric infrared sensor 6 and the alarm 7 respectively, the controller 5 controls the normal operation of the pyroelectric infrared sensor 6 and the alarm 7, and the pyroelectric infrared sensor 6 and the alarm 7 can also be manually turned off. The pyroelectric infrared sensor 6 and the alarm 7 are circuit-connected to the household circuit to ensure power supply, so as to monitor the window in real time. Once an outsider breaks into the window, the controller 5 controls the alarm 7 to give an alarm in time, achieving the effect of further improving the anti-theft performance and safety of the aluminum alloy doors and windows.

[0026] The implementation principle of an anti-theft aluminum alloy door and window in an embodiment of the present application is as follows: When the device is in use, by closing the two window sashes 4, the driving plug 8 is inserted into the slot 12. Subsequently, by rotating the knob 2, the second bevel gear 16 is driven to rotate. Through the meshing between the first bevel gear 15 and the second bevel gear 16, the threaded rod 11 is driven to rotate inside the limit groove 10. Since the threaded rod 11 is threadedly connected to the lifting plate 13, the lifting plate 13 is driven to move up and down along the inner wall of the limit groove 10. By connecting the lifting plate 13 to the insertion rod 17, the insertion rod 17 at the top of the lifting plate 13 is moved upward and inserted into the insertion hole 9 opened at the bottom of the plug 8, thereby fixing the window sash 4 and blocking it. By adding a pyroelectric infrared sensor 6 and an alarm 7, once an outsider breaks in through the window, the controller 5 controls the alarm 7 to give an alarm in time.
