Description

Technical Field

[0001] The utility model relates to the technical field of casement windows, in particular to a casement window with integrated double inward opening window screens. Background Art

[0002] Casement windows are divided into push-pull type and top-hung type. Their advantages are large opening area, good ventilation, good sealing, excellent sound insulation, heat preservation and anti-seepage performance. Inward-opening type is convenient for window cleaning; outward-opening type does not take up space when opened. The disadvantage is that the window width is small and the field of vision is not wide.

[0003] After searching, for example, a Chinese patent document discloses a casement window that can be opened in both directions [application number: CN202121176027.8]. This casement window that can be opened in both directions includes a main frame, a No. 1 support bar is fixedly installed at the lower end of the main frame, a No. 2 support bar is fixedly installed at the upper end of the main frame, an actuator is inserted and installed on the left and right sides of the main frame, a No. 2 window door is arranged on the left side of the main frame, and a No. 1 window door is arranged on the right side of the main frame, and the two actuators are inserted in the upper left and upper right parts of the No. 1 window door and the No. 2 window door, respectively, and a limiting device is arranged in the middle of the front end of the No. 1 window door and the No. 2 window door.

[0004] The device disclosed in the patent is provided with an operator and a limit device. Under the action of the operator, the No. 1 window door and the No. 2 window door can be opened in a double-opening manner. The limit device can improve the stability of the No. 1 window door and the No. 2 window door, thereby preventing the windows and doors from being damaged due to external factors. However, the patent cannot limit the doors and windows after they are opened, resulting in strong winds when they are opened, causing the doors and windows to shake violently. The shaking of the doors and windows and their contact with the frame will not only produce a lot of noise, but may also cause damage to the frame. Utility Model Content

The adjacent side surfaces of the two locking rings 11 are respectively fixedly connected with second protrusions 13 adapted to the locking groove 8. The upper surface of the locking platform 9 is provided with a second through groove 14 extending from its lower surface. The interior of the second through groove 14 is provided with a driving assembly. Through the above structure, the rotation of the rotating shaft 6 can be limited by tightening the two locking rings 11 at any angle of the door and window 2, and the angle of the connecting rod 27 is limited by the rotating shaft 6, thereby indirectly limiting the angle of the door and window 2, so that it will not close automatically even in strong winds, thereby avoiding contact with the frame 1 to cause noise and damage.

[0023] Furthermore, the driving assembly includes a displacement block 15, which is slidably connected to the inside of the second through groove 14, and the left and right side surfaces of the second through groove 14 are respectively rotatably connected with second connecting rods 16, and the opposite ends of the two second connecting rods 16 are respectively rotatably connected to the sliding protrusions 12, and a pull rod 17 is provided on the left side surface of the door and window 2, and a reset groove 18 is provided on the inner wall of the cavity 7. The rear end of the pull rod 17 slides into the interior of the cavity 7 through the reset groove 18, and a reset plate 19 is sleeved on the outer surface of the pull rod 17. A spring 20 is fixedly connected to the left side surface of the reset plate 19, and the other end of the spring 20 is fixedly connected to the inner wall of the reset groove 18, and the bottom wall of the cavity 7 is fixedly connected to a correction shaft 21, and the right end of the pull rod 17 is fixedly connected to a cable 22, and the cable 22 passes through the correction shaft 21 and is connected to the The front surface of the displacement block 15 is fixedly connected, and the adjacent ends of the two sliding protrusions 12 are respectively fixedly connected with the second springs 23, and the adjacent ends of the two second springs 23 are respectively fixedly connected with the inner walls of the two through grooves 10.

The lower surface of the frame 1 is fixedly connected with a drainage pipe 26, and the upper end of the drainage pipe 26 passes through the interior of the drainage groove 24. The bottom wall of the drainage groove 24 is arranged in an inclined shape. The inclined bottom wall of the drainage groove 24 can be used to concentrate the water flow and discharge it through the drainage pipe 26. Since the drainage pipe 26 is perpendicular to the ground and the diameter of the lower end of the pipe body is smaller than the upper diameter, the problems of the traditional structure being blocked from rainwater discharge due to strong winds can be minimized, thereby improving the smoothness and stability of drainage.

[0024] Working principle: When the door and window 2 is opened, the pull rod 17 is pulled to drive the reset plate 19 to move. When the reset plate 19 moves, the spring 20 is compressed synchronously, and when the pull rod 17 moves, the cable 22 is used to pull the displacement block 15 to move. After the displacement block 15 moves forward, the distance between the connection points at both ends of the second connecting rod 16 becomes smaller, and then the second connecting rod 16 is used to drive the two sliding protrusions 12 away from each other. When the two sliding protrusions 12 move away from each other, the second spring 23 is stretched synchronously, and the two locking rings are driven. 11 moves, and the two locking rings 11 stop contacting the outer surface of the rotating shaft 6 after movement, so that the doors and windows can be opened and closed at will. When the pull rod 17 is released, the pull rod 17 is reset under the action of the spring 20, and the two locking rings 11 are brought into contact with the rotating shaft 6 again with the help of the second spring 23, and the locking effect is improved with the help of the cooperation between the second protrusion 13 and the locking groove 8. At the same time, in windy and rainy weather, since the drain pipe 26 is perpendicular to the ground and the diameter of the lower end of the pipe body is smaller than the diameter of the upper end, the influence of strong wind on drainage is smaller, thereby improving the stability of drainage.
