[0024] Please refer to Figures 1 to 6, the present utility model provides a technical solution: an aluminum alloy anti-theft door and window with good sound insulation effect, including an external window frame 1. A cavity is provided on one side of the external window frame 1. Through holes are provided at the four corners of one side surface of the external window frame 1. A nut 2 is connected through a through groove on one side of the external window frame 1. The nut 2 penetrates to one end of the external window frame 1 and is fixedly installed with an internal window frame 3. Connecting grooves 4 are provided on both sides of one side surface of the internal window frame 3. A panel 5 is fixedly installed in the middle of one side surface of the internal window frame 3 through bolts. A through groove is provided in the middle of one side surface of the panel 5.

Sliding grooves 8 are provided on both sides of the front surface of the connecting plate 7. The inner arc surface of the sliding groove 8 is slidably connected with a transmission pin 9. A convex block 10 is provided on one side surface of the transmission pin 9. The number of the convex blocks 10 is two, and they are symmetrically distributed in a mirror image. The two convex blocks 10 are slidably clamped into the sliding groove 8. A transmission box 11 is fixedly installed on the back of the transmission pin 9. The inside of the transmission box 11 is a hollow structure. A side fixing plate 12 is fixedly installed on the inner back surface of the transmission box 11 through bolts. An arc end 121 is provided on one side of the side fixing plate 12. One side of the arc end 121 is fixedly installed on the inner back surface of the transmission box 11. An extension end 122 is provided in the middle of one side of the side fixing plate 12. A notch 123 is provided at the top of one side surface of the extension end 122. A support frame 13 is fixedly installed on the back of the transmission box 11. One side surface of the support frame 13 is fixedly installed on the inner wall of the external window frame 1 through bolts. A shaft rod is movably connected to one side surface of the side fixing plate 12. The shaft rod on one side of the side fixing plate 12 penetrates through the transmission box 11 and is fixedly installed with a driving gear 14. A driven gear 15 is movably connected to the outside of the transmission box 11 near the driving gear 14 through a shaft rod. The driven gear 15 is meshed and connected with the driving gear 14. A transmission rod 16 is fixedly installed on one side of the driven gear 15. A theft-proof rod 17 is installed through one side far from the driven gear 15 of the transmission rod 16.

[0025] During the swinging process of the transmission rod 16, when it reaches a certain position, the convex block 10 on one side of the transmission pin 9 slides to the bottom of the sliding groove 8 on one side of the connecting plate 7, thus achieving a limiting effect to prevent exceeding the moving range of the aluminum alloy anti-theft window panel 18. And when the theft-proof rod 17 reaches the lowest point, it will be fixed in the notch 123 on the surface of the side fixing plates 12 on both sides, thereby further improving the support effect. During the rotation of the aluminum alloy anti-theft window panel 18, it blocks in front of the window frame for anti-theft, and can also be lifted onto the window frame to avoid the problems of poor ventilation of a fully enclosed anti-theft door and the insecurity that a fence-type anti-theft door can be peeked into from the outside.

[0026] One side of the theft-proof rod 17 close to the transmission rod 16 is movably clamped into the notch 123 on one side of the side fixing plate 12. An aluminum alloy anti-theft window panel 18 is fixedly installed on the outer arc surface of the theft-proof rod 17. Sound insulation cotton 19 is provided inside the aluminum alloy anti-theft window panel 18.

[0027] Through the sound insulation cotton 19 provided on the aluminum alloy anti-theft window panel 18, the effect of re-isolating and absorbing noise is achieved, the sound insulation effect of the aluminum alloy anti-theft window during use is improved, and efficient sound insulation can be carried out.

[0028] In the present utility model, the working steps of the device are as follows:

[0029] Under normal circumstances or during the day, the aluminum alloy anti-theft window panel 18 on one side of the external window frame 1 swings to the top of the external window frame 1 driven by the transmission rod 16, which will not affect the direct sunlight, and placing it on the top of the window frame will not cause space occupation. When anti-theft is required, pull the aluminum alloy anti-theft window panel 18 to move from the top to the front end of the external window frame 1. During this process, the anti-theft rod 17 connected to the middle end of the aluminum alloy anti-theft window panel 18 is the power structure. The movement of the anti-theft rod 17 will cause the transmission rods 16 on both sides to swing accordingly, and its swing point will rotate around the driven gear 15 as the center. The driven gear 15 will drive the meshing driving gear 14 to rotate, and the driving gear 14 is a fixed point that can support the rotation of the driven gear 15. When the transmission rod 16 swings to a certain position, the convex block 10 on one side of the transmission pin 9 slides to the bottom of the chute 8 on one side of the connecting plate 7, thus achieving a limiting effect to prevent exceeding the movement range of the aluminum alloy anti-theft window panel 18. And when the anti-theft rod 17 reaches the lowest point, it will be fixed in the surface notch 123 of the side fixing plates 12 on both sides, thus further improving the support effect. During the rotation of the aluminum alloy anti-theft window panel 18, it blocks in front of the window frame for anti-theft, and can also be lifted onto the window frame to avoid the problems of poor ventilation of the fully enclosed anti-theft door and the insecurity of the lattice anti-theft door that can be peeked into from the outside. The sound insulation cotton 19 provided on the aluminum alloy anti-theft window panel 18 achieves the effect of re-isolating and absorbing noise, improves the sound insulation effect of the aluminum alloy anti-theft window during use, and can carry out efficient sound insulation.

[0030] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
