Background technique

In order to prevent mosquitoes from flying into the room and ensure good ventilation indoors and outdoors, people often install screens and screen doors on the windows or door bodies. The Chinese patent application number 95244635.9 discloses a cover for a rolling screen window. The outside of the cover adopts a circular arc structure, and the inside is a right-angle structure. A fixed self-tapping screw is respectively arranged at the upper and lower ends of the arc. The through hole, that is, leads from one end of the casing to the other end.

However, when the screen window is in use, the surface will be stained with a lot of dust, and for the winding type screen window, when it is retracted into the inside of the cover, the dust will also enter the inside of the cover, so the inside of the cover often needs to be cleaned and repaired, so design a It is particularly important to have a cover that is very easy to disassemble, so as to facilitate the cleaning and maintenance of the inside of the cover.

In the prior art, as the application number is 200420022687.0, a Chinese patent discloses a shell structure of a bead roller shutter type screen window, which is composed of front and rear shells and left and right supports, and the cross section of the rear shell is Right-angled shape, with a circular groove at the upper end, and a top groove at the lower end; the cross section of the front cover is a quarter arc shape, and a circular fillet matching the groove is provided at the upper end; another example is the patent The screen window cover with the application number 201420791764.2, including the front cover, the rear cover and the side cover, is connected through the front cover and the rear cover using the fixing buckle and the buckle groove, and the main arc hook of the rear cover and the front cover The secondary arc-shaped hook of the shell cooperates with this structure. When dismounting, only an oblique upward external force is applied to the front cover, and the front cover will break away from the rear cover, which is convenient for the disassembly of the cover.

However, there are still some deficiencies in the above-mentioned structures: the structure that the front cover and the rear cover are fastened through the groove and the circular fillet, or the outer contour of the fixing buckle and the inner contour of the buckle groove, not only the processing is relatively complicated, but also the accuracy is high. It is not easy to guarantee. If the accuracy is poor, it is easy to have problems such as weak connection of the front and rear covers and difficult disassembly, which will bring difficulties to the disassembly of the cover.
