DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 A door and window with a screen structure in this embodiment includes a window frame 1, an inner frame 2 is hinged inside the window frame 1, a screen frame 3 is arranged inside the inner frame 2, and a snap-on component is arranged on the screen frame 3.

[0023] The clamping assembly includes a movable block 9, which is slidably connected in an installation cavity 7 opened inside the screen window frame 3. A spring 8 is installed on one side of the movable block 9, and a limiting rod 10 is installed on the side of the movable block 9 away from the spring 8. A limiting groove 11 is opened on the inner side wall of the inner frame 2, and one end of the limiting rod 10 away from the movable block 9 passes through the screen window frame 3 and is inserted into the inside of the limiting groove 11. A receiving groove 6 is opened on one side of the inner frame 2, and the screen window frame 3 is clamped inside the receiving groove 6. A screen 4 is fixedly installed inside the screen window frame 3, and the spring 8 is installed inside the installation cavity 7.

[0024] In this embodiment, the side wall of the movable block 9 is rotatably connected to a pull rod 12, and a movable hole 14 connected to the installation cavity 7 is opened on the surface of the screen window frame 3. The end of the pull rod 12 away from the movable block 9 passes through the movable hole 14 and extends to the outside and is fixedly connected to a pull plate 13. The side wall of the screen window frame 3 is fixed with stoppers 15 located on the upper and lower sides of the movable hole 14, and the stoppers 15 are triangular structures.

[0025] It should be noted that there are four groups of snap-in components, which are respectively arranged at the four corners of the screen frame 3. By pulling the pull plate 13 to drive the movable block 9 to move, the limit rod 10 can be pulled out from the limit groove 11. After the pull plate 13 is moved between the two blocks 15, the pull plate 13 is rotated again so that the block 15 can block the pull plate 13, thereby preventing the limit rod 10 from moving back through the elasticity of the spring 8. The operation is performed in sequence to unlock the four corners, so that the screen frame 3 can be conveniently disassembled for replacement or cleaning.

[0026] It is worth mentioning that when installing the screen window frame 3, the screen window frame 3 is placed into the receiving groove 6, and the receiving groove 6 has a preliminary positioning effect on the screen window frame 3. Then, the pull plate 13 is rotated to make the pull plate 13 in a horizontal state, and the limiting rod 10 can be inserted into the inside of the limiting groove 11 through the elasticity of the spring 8, thereby fixing the screen window frame 3 on the inner frame 2, which is convenient for installation.

[0027] In this embodiment, the window frame 1 is hinged with a glass door and window frame 5 located on the back of the inner frame 2, a glass plate is installed inside the glass door and window frame 5, the inner frame 2 and the glass door and window frame 5 are both adapted to the inner wall of the window frame 1, and window handles are installed on the glass door and window frame 5 and the inner frame 2.

[0028] The width of the pull plate 13 is smaller than the spacing between the two stoppers 15 , so that the pull plate 13 can be easily pulled through between the two stoppers 15 . The pull plate 13 can then be rotated to fit against one side of the stoppers 15 , so that the stoppers 15 can stop the pull plate 13 .

[0029] It should be noted that, through the arrangement of the inner frame 2 and the glass door and window frame 5, ventilation can be achieved by first opening the inner frame 2 and then opening the glass door and window frame 5. If mosquitoes need to be prevented from entering, the inner frame 2 can be closed, which can achieve both ventilation and mosquito prevention effects.

[0030] The working principle of the above embodiment is: when the screen 4 needs to be cleaned, the pull plate 13 is pulled to drive the movable block 9 to move, and the pull rod 12 is made to slide in the movable hole 14, so that the limit rod 10 can be pulled out from the limit groove 11, and after the pull plate 13 is moved between the two stoppers 15, the pull plate 13 is rotated again so that the stoppers 15 can block the pull plate 13, thereby preventing the limit rod 10 from moving back through the elasticity of the spring 8. The operation is performed in sequence to unlock the four corners, so that the screen frame 3 can be conveniently disassembled for replacement or cleaning.
