The rotating mechanism includes a vertical plate 101 which is slidably connected to the inside of the outer frame 100. One end of the vertical plate 101 is welded with a sliding plate 102. One end of the inner wall of the outer frame 100 is fixed with a fixed plate 103 by bolts. One end of the fixed plate 103 is rotatably connected to a rotating rod 104. One end of the rotating rod 104 is fixed with a rotating frame 105 by bolts. The rotating frame 105 drives the rotating rod 104 to rotate. One end of the rotating frame 105 is cut with a sliding groove 106, and the width of the sliding groove 106 is greater than the diameter of the dial rod 108. The dial rod 108 is in clearance fit with the sliding groove 106. One end of the inner wall of the fixed plate 103 is fixed with a spiral spring A 107 by bolts. The spiral spring A 107 deforms to generate elastic force. One end of the spiral spring A 107 is rotatably connected to the rotating frame 105. The spiral spring A 107 uses the elastic force to pull the rotating frame 105. Above the vertical plate 101 is rotatably connected a dial rod 108 which is inserted into the sliding groove 106 to drive the rotating frame 105 to rotate. Below the sliding plate 102 is rotatably connected a push rod 201. Inside the outer frame 100 is fixed with a track 300 by bolts. The track 300 limits the movement trajectory of the sliding plate 102. Below the sliding plate 102 is fixed with a guide block 310 by bolts. The guide block 310 is slidably connected to the track 300 and slides along the inner wall of the track 300. One side of the vertical plate 101 is fixed with a telescopic rod 700 by bolts. The telescopic rod 700 is preferably an electric telescopic rod, which has a simple structure and a high accuracy in controlling the telescopic length. The telescopic rod 700 drives the sliding plate 102 to move. The opening and closing mechanism includes a push rod 201 which is fixed below the sliding plate 102 by bolts. One end of the push rod 201 is fixed with a workbench 202 by bolts. Above the workbench 202 is rotatably connected an L-shaped plate 203. The L-shaped plate 203 is at a right angle. The corner of the L-shaped plate 203 is rotatably connected to the workbench 202. One side of the workbench 202 is welded with a side plate 204. One end of the side plate 204 is fixed with a spiral spring B 205 by bolts. The spiral spring B 205 deforms to generate elastic force. One end of the spiral spring B 205 is fixed to the L-shaped plate 203. The spiral spring B 205 uses the elastic force to pull the L-shaped plate 203. One end of the L-shaped plate 203 is fixed with a round rod 206 by bolts. One end of the round rod 206 is rotatably connected to a rotating arm 207.

The connection block 208 is fixed to one side of the opening sash 200 by bolts. The connection block 208 drives the opening sash 200 to rotate. One side of the opening sash 200 is fixed with a hinge 400 by bolts, and one end of the hinge 400 is fixedly connected to the outer frame 100.

[0024] In this embodiment, when the telescopic rod 700 contracts, it drives the vertical plate 101 to move along the track 300, and then drives the push rod 201 to retreat. The push rod 201 drives the workbench 202 to move, and drives the L-shaped plate 203 to rotate while moving. Then, it drives one end of the swing arm 207 to rotate while moving, pushing one side of the opening sash 200 to open the opening sash 200. When it is necessary to close the doors and windows, the telescopic rod 700 extends to drive the vertical plate 101 to move along the track 300, drives the push rod 201 to advance, drives the L-shaped plate 203 to retract, and the swing arm 207 pulls the opening sash 200 to reset, realizing accurate closing of the doors and windows. When the opening sash 200 is opened, the spiral spring B 205 will pull the L-shaped plate 203 to enable it to quickly reset; It should be noted that the opening sash 200 and the clutch mechanism connected thereto can be arranged in parallel in multiple numbers. In this way, a separate window opening device can be used to uniformly drive multiple clutch mechanisms, so that multiple opening sashes 200 can be opened or closed through the clutch mechanism; It should be noted again that when multiple windows are linked, a longer track is set, and the track is only set within the moving stroke range of each clutch mechanism, so as to avoid unnecessary costs and potential risks brought by an overly long track; At the same time, when multiple windows are linked, the position of the connection block 208 can be set according to the sizes of multiple window openings 200.

[0025] When this embodiment is in use, when it is necessary to open the doors and windows, the telescopic rod 700 contracts, drives the push rod 201 to retreat, drives the L-shaped plate 203 to rotate while moving, pushes one side of the opening sash 200, and opens the opening sash 200. When it is necessary to close the doors and windows, the telescopic rod 700 extends to drive the vertical plate 101 to move along the track 300, drives the push rod 201 to advance, drives the L-shaped plate 203 to retract, and the swing arm 207 pulls the opening sash 200 to reset, realizing accurate closing of the doors and windows.

A support plate 305 is fixed to the bottom of the outer frame 100 by bolts, and the support plate 305 presses on the lever 302. A circular hole 306 is cut on one side of the workbench 202, and the circular hole 306 is in clearance fit with the push rod 303. The rod 303 can extend or retract along the circular hole 306. The locking mechanism includes a connecting plate 120, the connecting plate 120 is fixed to the inner wall of the opening sash 200 by bolts, a limiting groove 130 is cut in the middle position of the connecting plate 120, a notch 110 is cut on one side of the sliding plate 102, the notch 110 is triangular, and the triangular notch 110 can be inserted into the limiting groove 130 to press on the limiting groove 130. The limiting groove 130 is in clearance fit with the sliding plate 102.

[0027] In this embodiment, when the doors and windows are opened, the telescopic rod 700 contracts. Under the elastic action of the torsion spring 304, the lever 302 drives the push rod 303 to rise and insert into the circular hole 306 to limit the L-shaped plate 203. At this time, the L-shaped plate 203 cannot rotate along the workbench 202, enabling the doors and windows to be quickly opened. When the doors and windows are closed, the telescopic rod 700 extends, the push rod 201 drives the workbench 202 to move forward, the workbench 202 drives the lever 302 to move through the frame 301, the support plate 305 will press on one end of the lever 302. Under the elastic action of the torsion spring 304, one end of the lever 302 is lifted, pulling the push rod 303 out of the circular hole 306 to release the limit on the L-shaped plate 203, enabling the doors and windows to close slowly. During the forward movement of the sliding plate 102, it can drive the triangular notch 110 to insert into the limiting groove 130 to lock the doors and windows, preventing the doors and windows from shaking caused by the influence of wind force and ensuring the safety of the doors and windows.

[0028] When this embodiment is in use, when the doors and windows are opened, the telescopic rod 700 drives the workbench 202 to retreat. Under the elastic action of the torsion spring 304, the lever 302 drives the ejector rod 303 to rise and insert into the round hole 306 to limit the L-shaped plate 203. At this time, the doors and windows can be quickly opened. When the doors and windows are closed, the telescopic rod 700 extends to drive the workbench 202 to move forward. The support plate 305 will squeeze one end of the lever 302. Under the elastic action of the torsion spring 304, one end of the lever 302 is lifted, pulling the ejector rod 303 out of the round hole 306 to release the limit on the L-shaped plate 203. At this time, the doors and windows can be slowly closed. After the doors and windows are closed, under the separation action of the clutch mechanism, the slide plate 102 continues to move forward, driving the triangular notch 110 to insert into the limit groove 130 to lock the doors and windows.

[0029] A multi-window electric opening and closing device has the following specific working process: When the doors and windows need to be opened, the telescopic rod 700 contracts to drive the vertical plate 101 to move along the track 300, and then drives the push rod 201 to retreat.
