Description

Technical Field

[0001] The utility model relates to the field of doors and windows, in particular to a novel casement door and window profile capable of being installed with a double transmission system. Background Art

[0002] Casement doors and windows are common in daily buildings. They have a large opening area and good ventilation and sealing effects. However, existing casement doors and windows are generally single-leaf structures. In order to further improve the ventilation effect, double-leaf casement doors and windows are gradually becoming popular. Since casement doors and windows require frames of corresponding sizes to be locked, existing double-leaf casement doors and windows are to install the center column on one of the sash frames. When closing, it is necessary to close the sash frame with the center column first, and then close the other sash frame. However, this structure makes the handles of the two sash frames close to each other. Figure 1 As shown, the handle of one of the sash frames is locked in the center column. Although this can reduce the thickness of the window frame, the handles of the two window sashes are close to each other, so there is no space for installing screens. While maintaining ventilation, it does not have the effect of preventing mosquitoes. With the improvement of people's living standards, the demand for screens is gradually increasing. If the sash frame is replaced, the cost will increase greatly. If the existing sash frame is improved, this problem can be solved at a lower cost. Utility Model Content

[0003] The purpose of the utility model is to solve the problems in the background technology and provide a new casement door and window profile that can be installed with a dual transmission system. The profile only needs to replace the sash frame to complete the installation of the screen on the existing frame, which greatly saves production costs.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] The cam frame has a first end for receiving the second sash, and the second end for receiving the second sash is connected to the cam frame by the second sash, so that the cam frame can be connected to the sash frame by the second sash.

[0006] The side of the middle column of the fan frame close to the outside of the room is processed with an outer convex surface, and the outer convex surface is flush with the outer surfaces of the first fan frame and the second fan frame.

[0007] The novel casement door and window profile provided by the utility model and capable of being installed with a dual transmission system has the following beneficial effects:

[0008] (1) By extending the mounting grooves on both sides of the sash frame middle column, the width of the sash frame middle column is increased, thereby increasing the distance between the first sash frame and the second sash frame, thereby leaving sufficient clearance for the installation of the actuators of the first screen frame and the second screen frame. At the same time, avoidance steps are designed on the upper surfaces of the first screen frame and the second screen frame, which can make the structure of the entire casement door and window more compact and ensure the beauty of the casement door and window. In addition, the avoidance steps prevent the handles of the first sash frame and the second sash frame from interfering with the first screen frame and the second screen frame.

[0009] (2) By providing an outer convex surface on the center column of the sash frame, the outline of the center column can be formed outdoors, thereby preventing the thickness of the first sash frame from being too thick and affecting the beauty of the casement door and window.

[0014] Example

[0015] like Figure 2As shown, the new casement door and window profile that can be installed with a dual transmission system provided in this embodiment includes a first sash frame 1, a second sash frame 2 and a sash frame middle column 3, the sash frame middle column 3 is connected between the first sash frame 1 and the second sash frame 2, and the sash frame middle column 3 is connected to the first sash frame 1, and baffles 4 extending toward the first sash frame 1 and the second sash frame 2 are provided on both sides of the sash frame middle column 3. The baffles 4 can increase the thickness of the sash frame middle column 3, and the baffles 4 and the sash frame middle column 3 enclose an installation groove 5. The handles 7 of the first sash frame 1 and the second sash frame 2 are respectively connected to a transmission 8, and the transmission 8 extends into the installation groove 5, and the sash frame middle column 3 is clamped with the first sash frame 1, and the sash frame middle column 3 is installed with a first screen frame 9 and a second screen frame 10 on the side close to the interior. The first screen frame 9 is installed with a screen fan middle column 11 on the side close to the second screen frame 10, and the width of the screen fan middle column 11 is less than The fan frame has a central column 3, and the handles 7 of the first screen frame 9 and the second screen frame 10 are both located inside the screen fan central column 11. The first screen frame 9 and the second screen frame 10 are respectively processed with avoidance steps 12 to avoid the first fan frame 1 and the second fan frame 2 near the outdoor side. In this way, the handles 7 on the first fan frame 1 and the second fan frame 2 can be staggered with the handles 7 on the first screen frame 9 and the second screen frame 10, leaving enough space for the installation of the screen. At the same time, the handles 7 on the first fan frame 1 and the second fan frame 2 will not interfere with the first screen frame 9 and the second screen frame 10. The fan frame central column 3 is processed with an outer convex surface 6 near the outdoor side. The outer convex surface 6 is flush with the outer surfaces of the first fan frame 1 and the second fan frame 2. After the first fan frame 1 and the second fan frame 2 are closed, the outer convex surface 6 keeps the fan frame central column 3 in the center, thereby ensuring the beauty of the outdoor doors and windows.

[0016] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modification or replacement based on the technical solution and the concept of the present invention shall be included within the scope of protection of the present invention. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the present invention omits descriptions of known components and processing technologies and processes to avoid unnecessary limitations on the present invention.
