Only the preferred embodiments in the description are taken as examples. All other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present utility model.

[0027] As Figures 1-7 shown, the following technical solutions are adopted in this detailed implementation manner: It includes a window frame 1 and a window body 2. On both the left and right sides inside the window frame 1, the window body 2 is hinged through hinges. The window body 2 adopts double-layer laminated insulating glass, which has good sound insulation performance;

[0028] It also includes:

[0029] A fixed frame 3. The fixed frame 3 is fixedly arranged on the rear side edge inside the window frame 1. A first sealing strip 4 is fixedly arranged in a sealing groove opened on the front side wall of the fixed frame 3. The first sealing strip 4 abuts against the rear side wall of the window body 2. The first sealing strip 4 can improve the sealing performance between the fixed frame 3 and the window body 2. Several drain holes 11 are opened in the lower part of the fixed frame 3. Through the drain holes 11, it is beneficial to timely drain rainwater and the like inside the window frame 1. The inner bottom wall of the fixed frame 3 is arranged in a structure that slopes downward at the rear side, which can fully realize the diversion of rainwater and the like sliding on the inner bottom wall of the fixed frame 3 and on the window body 2 when the door or window is in the closed state;

[0030] A second sealing strip 5. There are four second sealing strips 5, which are respectively fixedly sleeved in two embedding grooves opened on the two window bodies 2, and the second sealing strip 5 abuts against the inner side wall of the window frame 1. The second sealing strips 5 on the left and right sides abut against each other. The second sealing strip 5 can not only improve the sealing performance between the window body 2 and the window frame 1, but also improve the sealing performance between the two window bodies 2;

[0031] Fixing strips 7. There are two fixing strips 7, which are respectively fixedly arranged on the front side walls of the two window bodies 2. On the upper and lower sides of the front side wall of the window frame 1, fixing blocks 8 are fixedly arranged. A convenient self-locking mechanism 9 connected to the fixing blocks 8 is arranged inside the fixing strip 7. A handle 6 is connected to the front side of the fixing strip 7 through the convenient self-locking mechanism 9;

[0032] The convenient self-locking mechanism 9 includes:

[0033] Vertical rods 9-1, there are two of the vertical rods 9-1, which are respectively movably arranged on the upper and lower sides inside the fixed strip 7. A limit ring 9-2 is fixedly sleeved on the vertical rod 9-1, and the limit ring 9-2 is movably arranged in a cylindrical groove 12 opened in the fixed strip 7. One end of the vertical rod 9-1 is hinged with a connecting rod 9-3, and the connecting rod 9-3 is movably arranged in a strip-shaped groove opened on the fixed strip 7. One end of the connecting rod 9-3 is hinged with the handle 6. On the upper and lower sides of the rear side wall of the handle 6, guiding telescopic rods 10 are fixedly arranged, and the guiding telescopic rods 10 are fixedly arranged in the fixed strip 7. The guiding telescopic rods 10 can not only provide guidance for the movement of the handle 6, but also keep the handle 6 at a fixed height all the time;

[0034] First springs 9-4, there are two of the first springs 9-4, which are respectively movably sleeved on the two vertical rods 9-1. The two ends of the first spring 9-4 are respectively connected with the limit ring 9-2 and the inner wall of the cylindrical groove 12. In a rectangular groove 14 opened at the other end of the vertical rod 9-1, a second spring 9-5 is fixedly arranged;

[0035] Rectangular rods 9-6, there are two of the rectangular rods 9-6, which are respectively movably inserted into the two rectangular grooves 14. One end of the rectangular rod 9-6 is fixedly connected with the second spring 9-5. The other end of the rectangular rod 9-6 passes through the rectangular groove 14 and then a limit rod 9-7 is fixedly arranged. One end of the limit rod 9-7 passes through the fixed strip 7 and is movably inserted into a slot 13 opened on the fixed block 8.

[0036] When using the present utility model, the handle 6 can be pulled forward, so that the guiding telescopic rods 10 extend. And the handle 6 can drive the upper and lower vertical rods 9-1 to move synchronously in the opposite direction through the two connecting rods 9-3. The limit ring 9-2 compresses the first spring 9-4 as the vertical rod 9-1 moves. The vertical rod 9-1 drives the limit rod 9-7 to move out of the slot 13 and move to the inner position of the fixed strip 7 through the second spring 9-5 and the rectangular rod 9-6. Then the window 2 can be rotated and opened as the handle 6 is pulled. And the first spring 9-4 resets and extends to push the limit ring 9-2, so that the limit ring 9-2 drives the vertical rod 9-1 to move to the initial position. The vertical rod 9-1 drives the handle 6 to move towards the fixed strip 7 through the connecting rod 9-3, shortening the guiding telescopic rods 10. At this time, one end of the limit rod 9-7 will also be exposed from the fixed strip 7 again. In the process of rotating the window 2 to the inner side of the window frame 1 for closing, through the abutting cooperation between the inclined side wall of the limit rod 9-7 and the inclined side wall of the fixed block 8, the limit rod 9-7 will be squeezed and move to the inner side of the fixed strip 7. At this time, the rectangular rod 9-6 moves towards the inner side of the rectangular groove 14 and compresses the second spring 9-5. After the window 2 is closed, the second spring 9-5 resets and extends, pushing the rectangular rod 9-6 towards the outer side of the rectangular groove 14. The rectangular rod 9-6 drives the limit rod 9-7 to be inserted into the slot 13, realizing self-locking in the closed state of the doors and windows.

[0037] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0038] 1. Through the cooperation of the fixing frame 3, the first sealing strip 4 and the second sealing strip 5, the doors and windows can have good sealing performance;
