[0028] In the using process, the user first pulls the push plate 14 to make it move in the sliding groove 5, and then drives the anti-theft plate 13 to slide in the installation slot 11, and exerts pressure on the spring 12 to make it shrink, through the setting of the hinge, the window frame 2 and the glass 3 can be rotated and closed on the inner wall of the installation frame 1, after being closed, the user releases the push plate 14, the spring 12 pushes the anti-theft plate 13 to slide to the appropriate position due to the elastic action, at this time, the horizontal direction outer surface of the anti-theft plate 13 is inserted into the inside of the anti-theft slot 21, and the positioning column 15 drives the push plate 14 to move, so that the positioning column 15 is inserted into the through hole 41 of the handle 4, thereby realizing the anti-theft locking function of the casement window in the closed state, if it is needed to be opened, the user pulls the push plate 14 to make the anti-theft plate 13 move and separate from the anti-theft slot 21, the spring 12 is extruded and shrinks, and at the same time, the positioning column 15 separates from the inside of the handle 4, then the user pulls the handle 4, and through the rotation of the hinge, the window frame 2 is opened.

[0029] As shown in Figure 4 - Figure 5As shown, the inner side of the mounting frame 1 is provided with a groove 101 on the upper and lower surfaces of the rear side, and a drainage groove 102 is provided on the lower side of the rear side of the mounting frame 1. The left side of the window frame 2 is provided with an anti-theft slot 21, and the length of the anti-theft slot 21 is less than the length of the window frame 2. The inner part of the anti-theft slot 21 is connected with the outer surface of the anti-theft plate 13 in the horizontal direction. The left side of the window frame 2 is connected with the right side of the anti-theft plate 13 in the vertical direction. The outer surface of the cylindrical block in the handle 4 is provided with a through hole 41 connected in the left and right directions. The inner part of the through hole 41 is connected with the outer surface of the positioning column 15 in the sliding mode. The upper and lower surfaces of the window frame 2 are fixedly connected with sealing strips 22 on the left and right sides. The lengths of the left and right sealing strips 22 are greater than the length of the window frame 2. The opposite surfaces of the left and right sealing strips 22 are fixedly connected with the left and right ends of the upper and lower sealing strips 22. The outer surface of the sealing strip 22 is connected with the inner part of the groove 101 in the top pressing mode. The side of the sealing strip 22 away from the window frame 2 is provided with a round corner. Two inclined surfaces are provided on the side of the sealing strip 22 close to the round corner in the front and back mirror image mode.

[0030] When the window frame 2 and the glass 3 are closed, the sealing strip 22 is ensured to be in contact with the mounting frame 1 and to be extruded, so that the sealing strip 22 is deformed. When the window frame 2 and the glass 3 are completely closed, the sealing strip 22 returns to the original state due to the elastic effect of the sealing strip 22, and is connected in the groove 101, so that the sealing effect is achieved, and rainwater is prevented from penetrating. The drainage groove 102 is provided, so that the rainwater in the groove 101 can be drained, and water accumulation is avoided. The round corner and the inclined surface of the sealing strip 22 are helpful to better contact with the mounting frame 1 when the window frame 2 is closed or opened, so that the sealing strip 22 is more effectively extruded. Conversely, when the window frame 2 is opened, the handle 4 is pulled by force, and the sealing strip 22 is driven. Due to the effect of the groove 101, the sealing strip 22 is extruded and shrunk again, so that the window frame 2 is easily opened.

[0031] The working principle of the anti-theft structure of the aluminum-plastic flat window will be described below.

[0032] After the window frame 2 and the glass 3 are closed, the user releases the push plate 14. The spring 12 pushes the anti-theft plate 13 to slide to the appropriate position due to the elastic effect, and the anti-theft plate 13 is inserted into the anti-theft slot 21. At the same time, the positioning column 15 drives the push plate 14 to move, so that the positioning column 15 is inserted into the through hole 41 of the handle 4, thereby realizing the anti-theft locking function of the flat window in the closed state. When the window frame 2 and the glass 3 are closed, the sealing strip 22 is ensured to be in contact with the mounting frame 1 and to be extruded, so that the sealing strip 22 is deformed. When the window frame 2 and the glass 3 are completely closed, the sealing strip 22 returns to the original state due to the elastic effect of the sealing strip 22, and is connected in the groove 101, so that the sealing effect is achieved, and rainwater is prevented from penetrating. The drainage groove 102 is provided, so that the rainwater in the groove 101 can be drained, and water accumulation is avoided.

[0033] The utility model has made the detailed description to the utility model generally, but can make some modification or improvement to it on the basis of the utility model, which is obvious to the general skilled person in the technical field. Therefore, the modification or improvement without departing from the utility model thought spirit, all are within the protection scope of the utility model.
