[0022] 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.

[0023] like Figures 1 to 4 As shown, the utility model provides a double inward opening casement window structure, comprising:

[0024] Frame 1;

[0025] The left and right ends of the inner side of the frame 1 are movably connected to the door and window 2 through a rotating shaft, and a horizontal plate 3 is fixedly connected to the inner side of the frame 1 and located between the door and window 2. The front end and the back end of the inner wall of the horizontal plate 3 are slidably connected to a fixing mechanism 4;

[0026] The fixing mechanism 4 includes a slider 41, a movable frame 42, a latch 43, a fixed column 44, a turntable 45 and a turning handle 46. The front end and the back end of the inner wall of the horizontal plate 3 are slidably connected with the slider 41, the front end of the slider 41 is fixedly connected with the movable frame 42, the left side of the movable frame 42 is fixedly connected with the latch 43, the left side of the latch 43 passes through the left side of the horizontal plate 3 and is plugged and fixed to the right side of the door and window 2, the inner cavity of the movable frame 42 is slidably connected with the fixed column 44, the top of the fixed column 44 passes through the top of the movable frame 42 and is fixedly connected with the turntable 45, the top of the turntable 45 is fixedly connected with the turning handle 46, the top of the turning handle 46 passes through the top of the horizontal plate 3 and is movably connected through the bearing seat.

[0027] refer to Figure 3 The front end and the back end of the inner wall of the horizontal plate 3 and the position corresponding to the slider 41 are both provided with a slide groove 5, and the slide groove 5 is used in conjunction with the slider 41.

[0028] As a technical optimization solution of the present invention, the slide 41 can move left and right inside the slide 5 by setting the slide 5, and at the same time play a role of limiting, thereby avoiding the phenomenon of displacement of the slide 41 during the movement.

[0029] refer to Figure 4 A rectangular groove 6 is provided on the surface of the movable frame 42 and corresponds to the position of the fixed column 44 , and the rectangular groove 6 is used in conjunction with the fixed column 44 .

[0030] As a technical optimization solution of the utility model, the rectangular groove 6 is provided to enable the fixing column 44 to move inside the rectangular groove 6 and at the same time play a limiting role, thereby avoiding the fixing column 44 from being separated during the movement.

[0031] refer to Figure 2 A sealing strip 7 is fixedly connected to the right side of the door and window 2, and the sealing strip 7 is used in conjunction with the door and window 2.

[0032] As a technical optimization solution of the utility model, the setting of the sealing strip 7 can assist the doors and windows 2 in their work, and at the same time play a role in sealing and noise reduction, thereby avoiding the effect of gaps between the doors and windows 2 and the frame 1 that cannot reduce noise.

[0033] refer to Figure 3 The surface of the turning handle 46 is provided with anti-skid patterns, and the turning handle 46 and the anti-skid patterns are used in conjunction with each other.

[0034] As a technical optimization solution of the present invention, the setting of the turning handle 46 can assist the turntable 45 in working, and at the same time increase the friction resistance, thereby avoiding the turning handle 46 from slipping during the rotation process.

[0035] refer to Figure 2 A groove 8 is provided at the top and bottom of the right side of the door and window 2 and at the position corresponding to the latch 43 , and the groove 8 is used in conjunction with the latch 43 .

[0036] As a technical optimization solution of the present invention, the provision of the groove 8 enables the latch 43 to be completely inserted into the groove 8, thereby avoiding the phenomenon that the latch 43 is stuck inside the groove 8 due to the groove 8 being too narrow.

[0037] The working principle and use process of the utility model are as follows: when in use, the door and window 2 are closed, and then the handle 46 is manually rotated clockwise. The rotation of the handle 46 drives the turntable 45 to rotate, and the rotation of the turntable 45 drives the fixed column 44 to rotate. The fixed column 44 rotates and cooperates with the movement of the rectangular groove 6 while forcing the movable frame 42 to move to the left. The movable frame 42 moves to the left and drives the slider 41 to move to the left. The slider 41 cooperates with the slide groove 5 to move to the left. Finally, the movable frame 42 drives the latch 43 to the left to extend out of the horizontal plate 3 until it is inserted into the inside of the groove 8 to lock and fix the door and window 2.

[0038] In summary: the double inward-opening casement window structure, through the coordinated use of the frame 1, the door and window 2, the horizontal plate 3, the fixing mechanism 4, the slider 41, the movable frame 42, the latch 43, the fixing column 44, the turntable 45 and the turning handle 46, solves the problem that the existing casement window is a whole and has a gap when locked after closing, which is prone to shaking.
