[0022] Figure 1-Figure 4 The utility model is a schematic diagram of the entire structure of a door and window leaf opening device and a sliding door and window, please refer to Figure 1-Figure 4 The present embodiment is a door and window leaf opening device and a sliding door and window thereof, comprising a door and window outer frame 1, wherein the inner side of the door and window outer frame 1 is provided with two parallel and staggered movable window frames 2, and the door and window outer frame 1 is connected to the movable window frame 2 by a sliding rail and a pulley to form a transverse sliding connection, the lower end of the inner side of the door and window outer frame 1 is provided with an installation cavity 11 along its length direction, and the upper part of the installation cavity 11 passes through the sliding rail groove inside the door and window outer frame 1, a driving sprocket 3 is rotatably installed at one end of the installation cavity 11, and a passive sprocket 4 is rotatably installed at the other end, and the driving sprocket 3 and the passive sprocket 4 are rotatably installed. A traction chain 5 is meshed and connected therebetween, and a rotation driving assembly 6 which can drive the active sprocket 3 to rotate is also provided on one side of the installation cavity 11. A shift block 7 is provided inside the lower end of the movable window frame 2, and one end of the shift block 7 extends to the outside of the movable window frame 2. A positioning bolt rod 71 is fixed to the bottom of the shift block 7 and vertically slidably installed inside the movable window frame 2. The bottom of the positioning bolt rod 71 has a pin block 72 embedded in the groove between the rollers of the traction chain 5. An elastic component 8 which abuts against the top of the shift block 7 and pushes the shift block 7 to move downward is also provided inside the movable window frame 2.

[0023] A bevel gear 1 31 is also fixed to one side of the driving sprocket 3; the rotation drive assembly 6 includes a DC reduction motor 61 fixed to the inside of the installation cavity 11, a rotating shaft 62 located at the output end of the DC reduction motor 61, a bevel gear 2 63 fixed to the outer end of the rotating shaft 62 and meshing with the bevel gear 1 31, and an elastic coupling 64 arranged on the rotating shaft 62. The transmission is smoother through the elastic coupling 64, and the motor and the linkage assembly are also protected; the inner bottom of the door and window outer frame 1 also has a limiting slide groove 12 connected to the installation cavity 11 along its length direction, and the lower end of the positioning bolt rod 71 is penetrated through the limiting slide groove 12 and enters the installation cavity 11. The limiting slide groove 12 is provided so that the positioning bolt rod 71 can move and operate normally. In this embodiment In the method, when the movable window frame 2 needs to be opened, the DC reduction motor 61 is started, and the DC reduction motor 61 drives the bevel gear 2 63 and the bevel gear 1 31 to rotate through the rotating shaft 62, thereby driving the driving sprocket 3 to rotate synchronously, and the driving sprocket 3 drives the passive sprocket 4 to rotate through the traction chain 5. The continuously rotating traction chain 5 can drag the positioning bolt rod 71 connected to it to move synchronously, thereby driving the movable window frame 2 to move left and right, so as to achieve the purpose of automatic opening of the window sash, and the opening size of the window sash can be freely adjusted by controlling the reciprocating rotation stroke of the motor. At the same time, the traction chain 5 has the characteristics of strong bearing capacity and stable transmission linearity, which is suitable for the opening and closing linkage of doors and windows. The entire transmission mechanism has the characteristics of simple structure, low cost and stable coordination.

[0024] It can be understood that the DC reduction motor 61 in this embodiment can be connected to the control switch through a wire, and can also be connected and controlled through a wireless module, such as NFC, Bluetooth, etc., a remote control terminal, so that the user can more conveniently operate the opening and closing of doors and windows.

[0025] Furthermore, sliders 73 slidably installed inside the movable window frame 2 are also provided on both sides of the positioning bolt rod 71, and the movable window frame 2 also has a slide groove corresponding to the slider 73. Through the provision of the slider 73 and the cooperation of the slide groove, the positioning bolt rod 71 is more linearly stable when moving up and down, which is conducive to the precise insertion of the pin block 72 into the roller groove of the traction chain 5; further, the elastic component 8 is a coil spring, and the adopted coil spring has the characteristics of simple structure, stable use and low cost.

[0026] The lower outer side of the movable window frame 2 is also provided with a finger groove 21 corresponding to the shift block 7. In actual use, when the driving mechanism controlling the opening and closing of the window sash fails or the power fails, the user can directly insert a finger into the finger groove 21 and push the shift block 7 upward, so that the positioning bolt rod 71 and the pin block 72 at the bottom directly disengage from the roller groove of the traction chain 5, so that the driving mechanism and the movable window sash are quickly separated. In this way, the user can push the movable window frame 2 to the left or right while holding the shift block 7 with his fingers, and the quick opening and closing operation of the window sash can be completed directly with one hand, which saves time and effort, and is simple and easy to use.

[0027] Furthermore, when the finger is released from the shift block 7, the shift block 7 and the positioning bolt rod 71 automatically move downward under the push of the elastic component 8, and are embedded in the groove between the rollers of the traction chain 5 through the pin block 72. In this way, a quick connection is formed between the drive mechanism and the movable window sash, which has a simple structure, good stability and is not easy to damage.

[0028] In summary, the present embodiment is a door and window opening device and its sliding door and window. When in use, the user directly starts the rotating drive assembly 6 to drive the active sprocket 3, the passive sprocket 4 and the traction chain 5 to rotate. The continuously rotating traction chain 5 can drag the positioning bolt rod 71 connected to it to move synchronously, and then drive the movable window frame 2 to move left and right, so as to achieve the purpose of automatic opening of the window sash. In addition, when the driving mechanism controlling the opening and closing of the window sash fails or the power is cut off, the user can directly insert his finger into the finger groove 21 and push the dial block 7 upward, so that the positioning bolt rod 71 and the pin block 72 at the bottom directly disengage from the roller groove of the traction chain 5, so that the driving mechanism and the movable window sash are quickly separated. In this way, the user can push the movable window frame 2 to the left or right while holding the dial block 7 with his finger. The quick opening and closing operation of the window sash can be completed directly with one hand, saving time and effort.
