The broken bridge casement window has two types: inward opening and outward opening. The sash of the inward opening window opens inward, which is convenient for cleaning and maintenance. The sash of the outward opening window opens outward, does not occupy indoor space, and has good waterproof performance, but there is a risk of the window falling off and being damaged.

[0003] Although the inward opening design of the broken bridge aluminum alloy casement window ensures safety, it requires some indoor space when opening the window door, which brings a lot of inconvenience to the users. In view of the above defects: For this reason, we propose a broken bridge aluminum alloy inward casement window that is convenient to open. Content of the Utility Model

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0028] Please refer to Figures 1-7 , the present utility model provides a technical solution: a casement aluminum alloy inner casement window that is easy to open, including a broken bridge aluminum main frame and a casement window 1. The broken bridge aluminum main frame is composed of a framework 2 and two columns 3 fixedly installed on the inner wall of the framework 2, and the two columns 3 divide the interior of the framework 2 into a glass placement cavity 4 and two window placement cavities 5. A glass 14 is arranged on the inner wall of the glass placement cavity 4, and a limit plate 15 that can limit the glass 14 is fixedly installed on the inner wall of the glass placement cavity 4. After applying glue to the glass 14, it is placed in the glass placement cavity 4, and at this time, the limit plate 15 can limit the glass 14.

[0029] A window opening structure is arranged on the surface of the casement window 1. The window opening structure is composed of a roller 6 that rolls in cooperation with the lower surface of the casement window 1 and an assembly structure arranged on the upper surface of the casement window 1.

[0030] The assembly structure includes a telescopic cylinder 7 fixedly installed on the upper surface of the casement window 1, and a sliding hole opened on the upper surface of the casement window 1, the inner wall of the sliding hole is slidably connected with a sliding cylinder 8, the inner walls of the sliding cylinder 8 and the telescopic cylinder 7 are both slidably connected with a telescopic rod 9, the upper end of the telescopic rod 9 is rollingly matched with a pulley 10, the inner walls of the sliding cylinder 8 and the telescopic cylinder 7 are both fixedly installed with a compression spring 13, and the other end of the compression spring 13 is fixedly connected to the lower end of the telescopic rod 9.

[0031] The inner top wall and the inner bottom wall of the frame 2 are both provided with a track groove 11 for the pulley 10 and the roller 6 to pass through, and the inner rear wall of the track groove 11 is provided with a limit groove 12 for the pulley 10 and the roller 6 to pass through, the limit groove 12 and the track groove 11 are interconnected, and a transition slope is provided at the intersection of the limit groove 12 and the track groove 11, and the pulley 10 and the roller 6 are both set to be spherical to facilitate their rolling in the limit groove 12 and the track groove 11.

[0032] First, place the roller 6 on the lower surface of the casement window 1 into the track groove 11, and then press the telescopic rod 9 to drive the telescopic rod 9 on the inner wall of the telescopic cylinder 7 and the sliding cylinder 8 to retract. At this time, the height of the pulley 10 will be reduced, so that the pulley 10 can easily enter the track groove 11 on the inner top wall of the frame 2. When the pulley 10 enters the track groove 11, the compression spring 13 resets and drives the telescopic rod 9 and the pulley 10 to reset. After the pulley 10 is reset, it will contact the inner wall of the track groove 11, so that the extended telescopic rod 9 can be used in conjunction with the roller 6 to limit the casement window 1, thereby facilitating the installation of the casement window 1.

[0033] A sealing plate 16 is fixedly mounted on the inner wall of the window placement cavity 5 . When the casement window 1 is in the window placement cavity 5 , the sealing plate 16 can limit the position of the casement window 1 .

[0034] After the casement window 1 is assembled in the window placement cavity 5 using the assembly structure, the pulley 10 and the roller 6 will be respectively located in the limit grooves 12 in the frame 2. When the casement window 1 needs to be opened, the casement window 1 is first pulled to drive the pulley 10 and the roller 6 to disengage from the limit groove 12 and move into the track groove 11. After that, the pulley 10 and the roller 6 can be moved laterally along the inner wall of the track groove 11. Compared with the prior art, the device utilizes the pulley 10 and the roller 6 in conjunction with the track groove 11 to enable the casement window 1 to achieve translation, thereby changing the traditional rotating window opening method, and thereby avoiding the problem of the casement window 1 occupying indoor space after opening.

[0035] An installation groove is provided inside the casement window 1, and the installation groove is communicated with the sliding hole. The inner wall of the installation groove is provided with a limit assembly that can limit the casement window 1. The limit assembly includes a cam 18 rotatably installed on the inner wall of the installation groove. The lower end of the sliding cylinder 8 extends to the inside of the installation groove, and a handle 19 is rotatably connected to the front of the casement window 1. The rotating shaft of the handle 19 is fixedly connected to the front of the cam 18. After the handle 19 is rotated, the cam 18 will rotate synchronously.

[0036] A sealing groove 17 is formed on the front surface of the sealing plate 16, and a sealing strip is arranged on one side of the casement window 1 close to the sealing groove 17. A lock catch 20 is rotatably connected to the back surface of the casement window 1, and the rotating shaft of the lock catch 20 is fixedly connected to the back surface of the cam 18. A lock groove adapted to the lock catch 20 is formed on the inner wall of the window placement cavity 5. When the lock catch 20 rotates into the lock groove, the casement window 1 can be fixed in the window placement cavity 5 by the cooperation of the lock groove and the lock catch 20. At the same time, the sealing strip will enter the sealing groove 17 to form a sealing surface. The sealing strip and the lock groove are not marked in the prior art drawings.

[0037] Rotating the handle 19 can drive the cam 18 to rotate. When the protruding end of the cam 18 contacts the lower end of the sliding cylinder 8, the cam 18 will drive the sliding cylinder 8 to rise. At this time, the compression spring 13 is stressed and will drive the pulley 10 to press against the track groove 11, so that the frictional force generated between the pulley 10 and the track groove 11 can be used to fix the casement window 1 and prevent the casement window 1 from moving easily.

[0038] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent replacement or change made by those skilled in the art according to the technical solution and concept of the present invention should be covered by the protection scope of the present invention.
