In order to solve the above problems, the utility model provides the following technical solutions: a casement window, comprising a window frame and a window door, the window door is rotatably connected to the opposite inner wall of the window frame, and the inner wall of the window frame is also provided with a horizontal The sliding slot is slidably connected with a slider, and a connecting rod is hinged between the slider and the window door; the slider is fixedly connected with a rack, and the inner wall of the slot is rotatably connected with a rotating shaft, so The rotating shaft is coaxially connected with a gear, the gear and the rack are engaged, the inner wall of the chute is also fixedly connected with a sleeve, the rotating shaft is located inside the sleeve, and the rotating shaft is provided with a sliding groove perpendicular to its axis A centrifugal block is slidably connected to the sliding groove, a limiting spring is connected between the centrifugal block and the sliding groove, and a resistance spring for restricting the movement of the centrifugal block is fixedly connected to the inner wall of the sleeve.

The working principle of the utility model: when the casement window is in normal use, the centrifugal block is located in the sliding groove. When the window door is pushed to the outside, because the connecting rod is hinged between the sliding block and the window door, the sliding block is slidably connected in the horizontal direction. Therefore, the window door that moves outward drives the slider to slide horizontally in the chute through the connecting rod. The slider drives the gear to rotate through the rack, and the gear drives the shaft to rotate. Because the speed of the shaft is slow at this time, The rotating speed of the centrifugal block is slow, and the centrifugal block will not protrude out of the sliding groove and contact the resistance spring, so the resistance spring cannot limit the rotation of the rotating shaft through the centrifugal block, and then limit the movement of the window door through the gear, rack and slider .

When the weather is strong wind, the strong wind blows the window door to quickly move towards the window frame, the window door pushes the slider to slide rapidly through the connecting rod, the slider then drives the gear to rotate rapidly through the rack, and the gear then drives the shaft to rotate rapidly. The rotating speed is large, and the centrifugal force received is large. The centrifugal block stretches the limit spring and moves toward the sliding groove. A part of the centrifugal block protrudes out of the sliding groove. Because one end of the resistance spring is fixed on the inner wall of the sleeve, the sleeve is fixed. On the inner wall of the chute, during the rotation of the centrifugal block, the centrifugal block is in contact with the resistance spring, and the elastic force of the resistance spring restricts the movement of the centrifugal block, thereby restricting the rotation of the rotating shaft, and the gear passes through the restricting rack, slider and connecting rod. The connecting rod finally stops the movement of the window door, which can prevent the window door from hitting the window frame.

Beneficial effects of the utility model: In this scheme, when the wind force is large, when the wind force pushes the window door to move rapidly, the window door drives the rotating shaft to rotate rapidly through the connecting rod and the rear gear of the slider. At this time, the rotating speed of the centrifugal block is large, and the centrifugal force received After the centrifugal block is in contact with the resistance spring, the gear restricts the movement of the window door through the rack, the slider and the connecting rod, which can prevent the window door from hitting the window frame.

Further, the inner wall of the sleeve is provided with a limit piece, and one end of the resistance spring is fixedly connected with the limit piece. By setting the limit piece, the axis of the resistance spring is perpendicular to the limit piece, and the limit piece can play a better limiting role in the compression direction of the resistance spring.

Further, the limiting piece is connected with a blocking piece for covering the resistance spring. The purpose of setting the baffle is that when the resistance spring is compressed, in order to avoid the arching of the resistance spring when it is compressed, so that the window and door cannot be better buffered, so the baffle is provided, and the baffle can limit the arching of the resistance spring, The resistance spring is effectively compressed in the direction of rotation of the centrifugal block.

Further, the window door is connected with a handle. The window door is easily opened by the handle.
