[0028] Specifically, the balancing mechanism also includes: a balancing plate 122, a welding plate 123, a spring support rod 124, a spring I125 and a sealing rubber plate 126. The balancing plate 122 and the slide groove I119 are slidably matched, the welding plate 123 is fixedly installed on the cylinder body II118, the spring support rod 124 passes through the balancing plate 122, the end of the spring support rod 124 is fixedly connected to the welding plate 123, the spring I125 is slidably installed on the spring support rod 124, and the sealing rubber plate 126 is slidably installed in the pressure relief channel 103.

[0029] Specifically, the correction mechanism also includes: a connecting rod 146, a slide plate III147 and a push rod 148. The connecting rod 146 and the pressure rod 139 are fixedly connected. The slide plate III147 is fixedly installed on the window outer frame 101. The push rod 148 passes through the slide rod support plate 105 and is slidably installed on the slide plate III147. One end of the push rod 148 is fixedly connected to the connecting rod 146.

[0030] Specifically, the opening and closing mechanism also includes: a spherical surface 154, a spring limit plate 155 and a spring III156. The spherical surface 154 is arranged on the push rod I153, the spherical surface 154 is in contact with the groove plate inclined surface 152, the spring limit plate 155 and the push rod I153 are fixedly connected, and the spring III156 is slidably installed on the push rod I153.

[0031] When the present invention is implemented: the outer window frame 101 is fixedly connected to the window, the inner window frame 102 is fixedly connected to the outer window frame 101, there is a certain pressure in the cylinder II118, the push plate 110 on the inner window frame 102 is in contact with the piston rod 116, and the pressure on both sides of the sliding plate 121 is equal. When the window sash I107 is unbalanced, one group of piston rods 116 will be pushed to move in the cylinder I115 through the push plate 110, and the other group of piston rods 116 will not move because they are limited due to stroke reasons. The moving group of piston rods 116 will cause the pressure on both sides of the sliding plate 121 to be unbalanced, and the side with greater pressure will squeeze the sliding plate 121 to move toward the side with less pressure. With the assistance of two groups of springs I125, the sliding plate 121 can be reset to the position where the pressure on both sides of the sliding plate 121 is equal, so that the window sash I107 can maintain a balanced state.

[0032] The motor 127 rotates forward through the screw 130 to drive the nut seat 134 to move, and the movement of the nut seat 134 drives the nut seat connecting plate 135 to slide on the slide groove II133. When the nut seat connecting plate 135 moves, it drives the pull shaft 136 to move synchronously. When the pull shaft 136 moves, it drives the moving plate 106 and the push rod I153 to move synchronously. When the spherical surface 154 is always in contact with the groove plate inclined surface 152 due to the relationship of the spring III156, when the push rod I153 drives the spherical surface 154 to move synchronously, the spherical surface 154 drives the push rod I153 to move laterally due to the relationship with the groove plate inclined surface 152, and the push rod I 153 moves laterally to compress the spring III156. When the push rod I153 moves, it pushes the push rod 148 to slide in the slide plate III147. When the push rod 148 moves, it drives the pressure rod 139 to move in the slide groove III138 on the slide plate II137 through the connecting rod 146. When the pressure rod 139 moves, it compresses the spring II145. When the pressure rod 139 moves, it drives the calibration block 141 to move synchronously. The calibration block 141 moves and makes the calibration groove 142 contact with the balance plate 122 to calibrate the balancing device to ensure that the window sash I107 will not be unsmoothly opened and closed due to imbalance when moving.

[0033] After the push rod I153 moves sideways for a certain distance, the push rod I153 and the push rod 148 are disengaged, and the push rod 148 is reset by the spring II145. After the push rod I153 moves a certain distance, the push rod I153 contacts the push plate 110 and drives the window sash I107 to move synchronously through the push plate 110 to perform the window opening operation. When the motor 127 rotates in the opposite direction, the piston rod 116 is reset due to the pressure in the cylinder body II118. The piston rod 116 is reset and pushes the window sash I107 to move synchronously through the push plate 110 to perform the window closing operation. The push plate 110 allows the window sash I107 to move at a constant speed due to the limit of the push rod I153.

[0034] When the push rod I153 initially moves, the balance plate 122 will be preferentially contacted with the calibration groove 142. After the balance plate 122 and the calibration groove 142 are in contact, the push rod I153 continues to move to push the push plate 110 to move. After the push rod I153 pushes the push plate 110 to move a certain distance, the push rod 148 is reset.

[0035] When a fire occurs, the sealing rubber plate 126 shrinks due to heat, the pressure in the cylinder II118 is released, and the window sash I107 falls rapidly due to its own weight.
