[0017] The technical scheme and technical effect of the utility model will be described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments.

[0018] As Figure 1 And Figure 3 A hook window sash anti-misplacement device, which comprises limiting blocks installed at the top of the window sash left and right sides respectively, the limiting block comprises a limiting panel 3, the limiting panel 3 is arranged on the inner side of the window frame side frame 5, and is used for preventing the window sash from moving along the hook axis. In order to ensure that the window sash can be smoothly opened or closed, the outer side surface of the limiting panel 3 is provided with chamfers at the junctions with the front and back two side surfaces.

[0019] The limiting panel 3 is provided with a protruding structure protruding into the inner side of the window sash side frame 7. The front and back two side surfaces of the inner end of the protruding structure are symmetrically provided with strip-shaped elastic extrusion parts 1, and the elastic extrusion parts 1 are inserted into the vertical slot at the top of the window sash side frame.

[0020] In the embodiment, the elastic extrusion part 1 comprises a plurality of flat sections 1-1 arranged in up-down direction on the side of the convex structure, and an arc section 1-2 is connected between adjacent flat sections 1-1, and a gap is left between the arc section 1-2 and the convex structure, and the flat sections 1-1 connected in up-down direction and the convex structure form a D-shaped structure. The D-shaped structure provides a larger elastic deformation space, and after being inserted into the vertical slot, the D-shaped structure is in close contact with the vertical slot under the action of elastic force, so that the insertion is more firm.

[0021] The top of the convex structure is provided with two front and rear symmetrical elastic limiting hooks 2 extending inwardly, and the hook bodies of the two elastic limiting hooks 2 form a buckle facing downward. In order to facilitate insertion, the top and bottom of the buckle are chamfered.

[0022] As Figure 2 and Figure 3 , when installing the device, the elastic extrusion part 1 is inserted into the vertical slot in the top of the window sash (the top of the window sash side frame 7 in the window sash) Figure 3 , and then the top is further pressed to be clamped in the horizontal groove in the top of the window sash (the top of the window sash upper frame 6 in the window sash) Figure 2 . After installation, the limiting panel 3 is always located inside the window frame side frame 5, and when the window sash is opened, the limiting panel 3 of the anti-displacement device on both sides close to the indoor side is still located beside the end slot 5-1 on the window frame side frame 5, which can prevent the window sash from being displaced along the hook shaft.
