DETAILED DESCRIPTION
[0023] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.
[0025] like Figures 1 to 5As shown, a linked door and window of a preferred embodiment of the present invention includes a first door and window 1, a second door and window 2 and a connecting device 3 arranged between the first door and window 1 and the second door and window 2, the first door and window 1 and the second door and window 2 are arranged in parallel, and the first door and window 1 and the second door and window 2 can move linearly, the connecting device 3 includes a fixed column 31, a rotating arm 32, a rotating shaft 33 and a movable column 34, the movable column 34 can move linearly along the length direction of the first door and window 1, the fixed column 31 is fixed on the second door and window 2, the first end of the rotating shaft 33 is inserted and fixed on the fixed column 31, the second end of the rotating shaft 33 is rotatably connected to the first end of the rotating arm 32, specifically, the second end of the rotating shaft 33 is inserted into the first end of the rotating arm 32, a bearing is provided between the rotating shaft 33 and the rotating arm 32, so that the rotating arm 32 can rotate more smoothly, and the rotating arm 32 can rotate around the rotating shaft 33, and the second end of the rotating arm 32 is connected to the movable column 34.
[0026] Therefore, in the embodiment of the present invention, the combination of the movable column 34 and the rotating arm 32 can make it possible for two adjacent linked doors and windows to be converted from the overlapping state to the expanded state, and the movable column 34 slides with the translation of the doors and windows until the movable column 34 abuts against the end of the first door and window 1, and the movable column 34 can no longer move. At this time, the rotating arm 32 can rotate around the rotating axis 33, so that the door and window can continue to move a certain distance, thereby greatly reducing the overlapping length between the two, so that the door and window are longer in the expanded state, with high space utilization, and can be applied to a variety of door opening methods, such as: flat-sliding doors and windows, sliding doors and windows, etc.
[0027] For example, Figure 4 As shown, the first door and window 1 and the second door and window 2 both include an upper frame, a left frame, a lower frame 11 and a right frame 12 connected in sequence, the lower end surfaces of the left frame and the right frame 12 are respectively inclined upward from the outside to the inside, and the upper end surfaces of the left frame and the right frame 12 are respectively inclined downward from the outside to the inside, and a first inclined connecting surface 13 that cooperates with the lower end surfaces of the left frame and the right frame 12 is provided between the left end surface and the upper end surface of the lower frame 11 and between the right end surface and the upper end surface of the lower frame 11, and a second inclined connecting surface that cooperates with the upper end surfaces of the left frame and the right frame 12 is provided between the left end surface and the lower end surface of the upper frame and between the right end surface and the lower end surface of the upper frame. Through the setting of the inclined connecting surfaces, the left frame and the right frame 12 can be supported on the lower frame 11, which increases the installation area, reduces the installation difficulty, and improves the stability of the structure.
[0028] For example, Figure 5As shown, the left and right end faces of the lower frame 11 are respectively provided with a first end cover 14, and the upper end face of the first end cover 14 is a third inclined connecting face 15 connected to and matched with the lower end face of the left frame or the right frame 12. By adding the first end cover 14 to the end of the lower frame 11, the left and right end faces of the upper frame are respectively provided with a second end cover, and the lower end face of the second end cover is a fourth inclined connecting face connected to and matched with the upper end face of the left frame or the right frame 12, which covers the lower frame, greatly improving the overall aesthetics of the door and window, as well as the stability of the left and right frames 12. At the same time, when it is necessary to inspect and repair the sliding parts or connecting parts, it is only necessary to remove the first end cover 14, and the loading and unloading is simple and convenient.
[0029] Exemplarily, the cutting angle of the lower end surfaces of the left frame and the right frame 12 is 45 degrees, which is more aesthetically pleasing. Of course, in other embodiments, the cutting angle may also be any angle less than 90 degrees.
[0030] Exemplarily, the rotating arm 32 is a U-shaped structure, and the rotating arm 32 includes a horizontal rod 322 and a vertical rod 323 connected to both ends of the horizontal rod 322. The horizontal rod 322 is a telescopic rod. Therefore, when the rotating arm 32 rotates, if the telescopic rod is extended, the doors and windows can still move a certain distance, so that the doors and windows can be installed more tightly with the door and window frames, with high sealing, and the dimensional accuracy requirements of the door and window frames are not high, and the installation is simple.
[0031] For example, Figure 3 As shown, a limit slot 311 is provided on the fixed post 31 or the rotating arm 32, and a limit block 321 is provided on the rotating arm 32 or the fixed post 31. The limit slot 311 cooperates with the limit block 321 to limit the rotation angle of the rotating arm 32. In this embodiment, the limit slot 311 and the limit block 321 are in the shape of a parallelogram, and a rotation gap 35 is provided between the groove wall of the limit slot 311 and the side wall of the limit block 321 for the rotation of the rotating arm 32. Preferably, the gap is 5 mm. Specifically, the limit slot 311 is provided on the fixed post 31, and the limit block 321 is provided on the rotating arm 32, and a stepped structure is formed between the limit slot 311 and the fixed post 31, and between the rotating arm 32 and the limit. Therefore, the size of the gap can be better controlled to control the length of the overlapping position to prevent the overlapping position from being too large or too small. At the same time, the structure is simpler and easier to process.
[0032] Exemplarily, the first door and window 1 and the second door and window 2 both include an upper frame, a left frame, a lower frame 11 and a right frame 12 connected in sequence, and a slide groove 16 is provided in the length direction of the upper frame or the lower frame 11, and the movable column 34 is slidably connected to the slide groove 16. Specifically, the movable column 34 is connected to the first door and window 1 through a linear motion pair 37, and the linear motion pair 37 can be a structure such as a gear rack to ensure the smoothness of the sliding of the movable column 34. It should also be noted that a fixed groove is provided in the length direction of the upper frame or the lower frame 11, and the fixed column is arranged in the fixed groove.
[0033] In order to facilitate the fixing of the rotating shaft 33 , the first end of the rotating shaft 33 is fixed to the fixing column 31 via a positioning pin 36 .
[0034] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
