Detailed Description

In order to make the technical solution of the present invention better understood, the present invention is described in detail below with reference to the accompanying drawings, and the description of the present invention is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention.

Referring to fig. 1 to 8, in a specific embodiment, a detachable aluminum alloy door/window screen door comprises a screen sash 2 hinged on a window frame 1, wherein the screen sash 2 is provided with a rectangular hole for installing a screen panel 3; at least four corners of the rectangular hole are provided with rotatable clamping discs 4 for pressing four corners of the screen window plate 3.

As shown in fig. 2, further optimization is performed on the basis of the above embodiment: the clamping disc 4 is of a fan-shaped structure. The sector surface of the clamping disc is rotated to press the screen window plate, and then the screen window plate can be fixed on the screen sash 2.

As shown in fig. 6, further optimization is performed on the basis of the above embodiment: the fan-shaped included angle of the clamping disc 4 is less than or equal to 270 degrees. When the fan-shaped included angle of the clamping disc 4 is 270 degrees, the clamping disc is rotated, so that the screen window plate can be taken out when the 90-degree notch is matched with the screen window plate.

As shown in fig. 6-7, in order to improve the fixing stability of the clamping disc to the screen plate, the above embodiment is further optimized: the bottom surface of the clamping disc 4 is provided with a clamping bulge 42 for fixing the screen plate 3. The screen board is pressed and fixed by the blocking bulge 42.

As shown in fig. 3-4, further optimization is performed on the basis of the above-mentioned embodiments: the clamping protrusion 42 is a pin; the four corners of the screen plate 3 are provided with arc-shaped grooves 33 for clamping the pins.

As shown in fig. 3-4, in order to prevent the screen plate from falling off due to the displacement of the clamping disc caused by the wind blowing or the long-term opening and closing vibration of the window, the above embodiment is further optimized: the inlet of the arc-shaped slot 33 is higher than the bottom surface. When the clamping disc is rotated, the clamping bulges 42 are just clamped into the cutter arc-shaped groove 33, so that the screen window plate and the clamping disc are combined and fixed, the installation stability is improved,

in order to prevent the window from being blown by wind or prevent the screen window plate from falling off due to the displacement of the clamping disc caused by the long-term opening and closing vibration, the screen window is further optimized on the basis of the embodiment: the clamping bulge 42 is a magnet; iron pieces 34 for generating attraction with the magnets are arranged at four corners of the screen plate 3. The clamping protrusion 42 and the iron sheet 34 are mutually attracted and fixed, so that the screen plate can be prevented from falling off due to the rotation angle displacement of the clamping disc caused by external force vibration.

As shown in fig. 6, in order to further improve the fixing firmness of the clamping disc to the screen plate, the above embodiment is further optimized: the bottom surface of the clamping disc 4 is provided with a convex pressing strip 43. The pressing strip 43 is arc-shaped and fixed on the clamping disc 4, and the pressing strip can be made of elastic material.

In order to improve the installation stability of the screen panel 3, a plurality of clamping discs 4 may be provided around the installation hole of the screen 2.

The utility model discloses concrete theory of operation:

as shown in fig. 1, the screen 2 is hinged to the window of the window frame 1, the screen 2 is opened to expose the screen panel 3 mounted on the inner surface, the clamping disc 4 is rotated to separate the clamping disc 4 from pressing the screen panel 3, and then the screen panel 3 can be unloaded for replacement or cleaning.
