[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] See also Figure 1-7 The utility model provides a technical solution: a soundproof and heat-insulating safety door and window, comprising an aluminum alloy frame 1, a first door and window frame 2 and a second door and window frame 3, the first door and window frame 2 and the second door and window frame 3 are respectively slidably arranged on both sides of the inner cavity of the aluminum alloy frame 1, and the first door and window frame 2 and the second door and window frame 3 are staggered, and hollow soundproof and heat-insulating glass 4 is installed inside the first door and window frame 2 and the second door and window frame 3.

[0020] A groove 5 is provided on the rear side of the first door and window frame 2, and a rotating shaft 6 is rotatably provided on one side of the inner cavity of the groove 5 through a bearing, and one end of the rotating shaft 6 extends to the outside of the first door and window frame 2, and the end of the rotating shaft 6 extending to the outside of the first door and window frame 2 is fixedly connected to a crescent lock plate 7, and a lock catch 8 used in conjunction with the crescent lock plate 7 is fixedly connected to one side of the inner cavity of the second door and window frame 3. A rubber pad 9 used in conjunction with the groove 5 is fixedly connected to the rear side of the first door and window frame 2, and a compacting plate 10 is slidably connected to the inside of the groove 5, and the compacting plate 10 is fixedly connected to the rubber pad 9. A bevel gear 11 used in conjunction with the compacting plate 10 is fixedly connected to the surface of the rotating shaft 6 and located inside the groove 5;

[0021] Furthermore: in order to further improve the sound insulation and heat insulation effect of the device, the rear side of the inner cavity of the aluminum alloy frame 1 is filled with heat insulation cotton 20, and the front side of the inner cavity of the aluminum alloy frame 1 is filled with honeycomb sound-absorbing cotton 21;

[0022] As a detailed explanation: a guide groove 16 is provided at the top and bottom of the front side of the inner cavity of the groove 5, and a guide slide rod 17 that slides and adapts to the guide groove 16 is fixedly connected at the top and bottom of the front side of the compacting plate 10, and a second return spring 18 is fixedly connected between the compacting plate 10 and the groove 5, and two second return springs 18 are symmetrically arranged above and below.

[0023] Furthermore: in order to improve the locking stability of the crescent lock plate 7 and the lock buckle 8, a double-split slide groove 12 is provided on one side of the crescent lock plate 7, and a locking rod 13 is slidably connected to one side of the inner cavity of the double-split slide groove 12.
