[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-6The application discloses an aluminum alloy door and window with replaceable screen, which comprises a window frame 1, a back plate 11 fixedly arranged on the window frame 1, a detachable screen body 2 mounted on the front of the back plate 11, and active cavities 12 formed on the upper and lower sides of the window frame 1. A connecting rod 31 is vertically arranged in each of the active cavities 12, a plurality of limiting pieces 3 are fixedly arranged on one side of the connecting rod 31 towards the screen body 2, a through cavity communicating with the outside is formed on the active cavity 12 corresponding to each of the limiting pieces 3, and a limiting groove 21 is formed on the screen body 2 corresponding to each of the limiting pieces 3.

[0022] A plurality of spring cavities 4 are formed on one side of the window frame 1 corresponding to the active cavities 12, and the spring cavities 4 are perpendicular to the active cavities 12. A spring 41 is mounted in each of the spring cavities 4 towards the connecting rod 31, and the other end of the spring 41 is connected with the connecting rod 31. The spring 41 can push the connecting rod 31 outward, so that the limiting pieces 3 can be stably clamped in the limiting grooves 21.

[0023] An adjusting rod 32 is fixedly and vertically arranged on the connecting rod 31, and an adjusting cavity 13 communicating with the outside is formed on the window frame 1 corresponding to the adjusting rod 32. The adjusting rod 32 passes through the adjusting cavity 13 and extends out of the window frame 1, and an adjusting handle 33 is fixedly arranged on the end of the adjusting rod 32 extending out of the window frame 1. The adjusting handle 33 can facilitate the user to operate the adjusting rod 32.

[0024] The limiting piece 3 passes through the through cavity and extends out of the active cavity 12, and the side of the limiting piece 3 away from the back plate 11 is provided with an inclined surface.

[0025] In the embodiment, when the user needs to install the screen body 2 on the window frame 1, the screen body 2 is directly placed in front of the back plate 11. At this time, the limiting pieces 3 are extruded and moved into the active cavities 12 due to the elastic force of the springs 41, but the front of the limiting pieces 3 is provided with an inclined surface. Therefore, when the screen body 2 contacts the limiting pieces 3, the limiting pieces 3 can be automatically extruded and moved into the active cavities 12.

[0026] When the screen body 2 is completely assembled in front of the back plate 11, the limiting grooves 21 on the screen body 2 are aligned with the through cavities on the active cavities 12. At this time, the limiting pieces 3 are automatically reset by the elastic force of the springs 41, so that the limiting pieces 3 can be clamped in the limiting grooves 21 on the screen body 2. At this time, the rear of the screen body 2 is clamped by the back plate 11, and the front of the screen body 2 is clamped by the plurality of limiting pieces 3, so that the screen body 2 can be quickly installed.

[0027] Further, when the user needs to remove the screen body, the user only needs to pull the adjusting handle 33 outward. Thus, the connecting rod 31 is moved by the adjusting handle 33, and the spring 41 is compressed at this time, and the limiting piece 3 returns to the activity cavity 12 along with the connecting rod 31. At this time, the clamping between the limiting piece 3 and the limiting groove 21 is released, and the user can directly remove the screen body 2.

[0028] Further, the user only needs to pull one side of the adjusting handle 33, and the clamping between the limiting piece 3 and the limiting groove 21 on the side is released. Thus, the screen body 2 on the side is loosened, and the screen body 2 on the side can be slightly moved, so that the limiting groove 21 on the side is no longer aligned with the through cavity, and the limiting piece 3 cannot be normally reset in the limiting groove 21. At this time, the user can pull the adjusting handle 33 on the other side outward, so that the user does not need to pull the adjusting handle 33 on both sides at the same time, and the convenience of single-person disassembly is improved.

[0029] In the utility model, through the mutual clamping between the limiting groove 21 and the limiting piece 3, and the setting of the back plate 11, the screen body 2 can be quickly installed, and the screen body 2 is conveniently disassembled.

[0030] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, and any person skilled in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, and all of them should be covered in the protection scope of the utility model.
