At present, casement doors and windows refer to two or more parallel or vertical points that are fixed on the side of the hole and the mouth, and can be opened manually, electrically, chain, twist, rotate, and magnetically, and have certain ventilation and lighting performance. and locking function doors and windows.

The existing invention patent with the publication number of CN106761230A provides an aluminum profile casement door and window. This door and window includes a frame and a middle stile, the middle stile or frame adopts an indoor pressing line, and the indoor pressing line is clamped with the middle stile or frame to fix the glass, forming an indoor side splicing seam and a fixed glass side splicing seam. Thereby, the problems of easy dust accumulation and inconvenient cleaning of the existing exterior pressing line are solved, and the splicing seam is reduced.

The above-mentioned prior art scheme has the following defects: when it rains, the rainwater will directly fall on the bottom of the window sash, and the rainwater on the upper part of the window sash will also flow to the bottom of the window sash, and the bottom of the window sash is connected with the window frame. There are many gaps, like a flat open There will be gaps where the support rods are installed at the bottom of the window, and rainwater will seep through the gap, causing water to enter the window.

Utility model content

Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a casement window, which has the effect of enhancing the blocking effect of rainwater when it rains.

The above-mentioned utility model purpose of the present utility model is achieved through the following technical solutions: a casement window, comprising a window frame arranged on a wall body, the window frame is provided with a window sash that is rotatably connected with the window frame, and the window The outer bottom surface of the frame on the outside side of the window is provided with a water blocking plate that fits with the outer bottom surface of the window sash. The length of the water blocking plate in the horizontal direction is greater than the length of the window sash. The ends are symmetrically provided with fixed blocks, the opposite surfaces of the two fixed blocks are symmetrically provided with first shaft holes, and the bottoms of both sides of the water baffle are fixedly provided with first rotating shafts matched with the first shaft holes. A rotating shaft is arranged parallel to the length direction of the water baffle, and an elastic member is arranged between the water baffle and the fixing block for driving the water baffle back to the position where it is attached to the outer bottom surface of the window sash.

By adopting the above technical solution, when the window is closed, the water blocking plate will be attached to the bottom of the window sash and the window frame under the action of the elastic member. When the window is opened, the sash will squeeze the water baffle, and the water baffle will rotate downward under the action of the rotating shaft. When the window is closed when it rains, the water baffle will rotate upwards under the action of the elastic member and re-fit with the outer bottom surface of the window sash, so as to prevent the rainwater from directly hitting the gap between the bottom of the window sash and the window frame, thereby enhancing the safety of the window. Waterproof effect.

The utility model is further provided that: the elastic member comprises a coil spring, the coil spring is sleeved on the first rotating shaft, one end of the coil spring is connected to the first rotating shaft, and one end is connected to the fixing block.

By adopting the above technical solution, when the window is opened, the water blocking plate is squeezed by the bottom of the window sash and rotates around the rotating shaft, and the coil spring is tightened at this time. spring back to its original position.

The utility model is further configured as follows: a ratchet wheel arranged in a fan shape is fixedly connected on the first rotating shaft between the water blocking plate and the fixing block, and the fixing block is provided with a convex ring with the same circle center as the first rotating shaft, so the A movable disk is rotatably connected to the convex ring, the movable disk is arranged in a fan shape, the outer diameter of the movable disk is larger than the outer diameter of the ratchet, and the surface of the ratchet facing the movable disk is provided with a stop point, so The movable plate is provided with an arc-shaped groove that cooperates with the stop point, the stop point and the arc-shaped groove are slidably connected, and the fixed block is rotatably connected with a pawl that engages with the ratchet, and the pawl faces The axial center position of the ratchet wheel is set, the thickness of the ratchet pawl is greater than the sum of the thicknesses of the ratchet wheel and the movable disk, and the fixed block is provided with a torsion spring that drives the ratchet pawl to rotate toward the ratchet wheel.
