DETAILED DESCRIPTION

[0043] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be described below in conjunction with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0044] Reference is made to Figure 1 , Figure 2 The related technical product drawings relate to the fact that most existing inward-opening and inward-falling hardware and sashes have no anti-shaking adjusting structure. The long connecting plate one 38 is riveted and fixed with the first flat opening lock block one 39. During the opening process of the sash 37 or when the sash is in a flat opening state and subjected to external force, the sash will shake, and the sash will transmit the shaking to the flat opening connecting rod one 40, and finally to the long connecting plate one 38, so that the long connecting plate one 38 and the sash 37 shake, affecting the service life and use experience.

[0045] The embodiments of the present application provide a hidden upper hinge for windows, which is installed at the upper part of a sash and a window frame. Referring to Figures 3-19 , the hinge comprises an anti-shaking adjusting assembly and an opening and closing assembly,

[0046] The anti-shaking adjusting assembly comprises a first flat-opening locking block 22, an anti-shaking adjusting screw 20 and an anti-shaking contact head 21. The first flat-opening locking block 22 is provided with a mounting groove perpendicular to the length direction of the first flat-opening locking block 22 at the bottom of the first flat-opening locking block 22. The anti-shaking contact head 21 and the anti-shaking adjusting screw 20 are accommodated in the mounting groove. The anti-shaking adjusting screw 20 is used to adjust the distance of the anti-shaking contact head 21 from the mounting groove.

[0047] The anti-shaking adjusting assembly is mounted on the top of the sash 37 and connected with the window frame through the opening and closing assembly.

[0048] Referring to Figures 3-5 , the first flat-opening locking block 22 is connected with the long connecting plate 17 through riveting. The first flat-opening locking block 22 is provided with a mounting groove structure perpendicular to the length direction at the bottom of the first flat-opening locking block 22. The anti-shaking adjusting screw 20 is located in the mounting groove and can rotate in the mounting groove. The mounting groove simultaneously plays a role of limiting the front and back and left and right movements of the anti-shaking adjusting screw 20. The tail end of the anti-shaking adjusting screw 20 is connected with the anti-shaking contact head 21 through threads. The anti-shaking contact head 21 is located in the mounting groove of the first flat-opening locking block 22. The front and back movements of the anti-shaking contact head 21 in the mounting groove can be realized by rotating the anti-shaking adjusting screw 20. The first flat-opening locking block 22 can play a role of limiting the left and right movements of the anti-shaking contact head 21.

[0071] The upper hinge for window provided by the utility model, the fixing and installation can be realized through the following structure:

[0072] The installation of the hinge and the window frame adopts the clamping and top wire type fixing mode, referring to Figure 12The upper hinge frame base 3 is L-shaped, including a horizontal part and a vertical part. The L-shaped long side, i.e. the horizontal part, is connected and fixed with the upper hinge bottom plate 5 through the upper hinge rivet one 14 and the upper hinge rivet four 2. The upper hinge bottom plate 5 is in contact with the upper edge of the European C-shaped window frame slot 43, and the installation and positioning are realized after the two sides are in sufficient contact. The L-shaped short side, i.e. the vertical part, is in contact with the upper edge of the European C-shaped window frame slot 43. See Figure 13 , 14 The rotating nut 9 is rotated to be in sufficient contact with the inner wall of the vertical European C-shaped window frame slot 43 of the window frame, so as to achieve clamping. Meanwhile, the special-shaped screw 10 and the inner hexagonal pointed screw 6 can be further rotated to be embedded into the inner wall of the aluminum profile wall thickness, so as to achieve locking. The installation and dismounting mode is simple and efficient, the efficiency of the hinge installation and dismounting is improved, and the installation difficulty is reduced.

[0073] Further, see Figure 18 The inner hexagonal countersunk screw 7 is connected with the upper hinge frame base 3 through the thread, and the inner hexagonal countersunk screw 7 is loosened to enable the sealing adjustment block 8 to move left and right relative to the upper hinge frame base 3, so as to realize the compression of the sealing adjustment block 8 to the bolt 44.

[0074] The upper hinge frame base 3 is provided with a riveting hole, so that the rotating nut 9 is riveted and connected with the upper hinge frame base 3, and the rotating nut 9 can rotate in the riveting hole of the upper hinge frame base 3. The upper hinge frame base 3 is provided with a thread, so that the special-shaped screw 10 is threadedly connected with the upper hinge frame base 3.

[0075] See Figure 19 The limiting block 11 is provided with a clamping position which is slightly smaller than the corresponding clamping position of the upper hinge frame base 3, so that the limiting block 11 is elastically deformed and firmly clamped with the upper hinge frame base 3. The end surface of the limiting block 11 is overlapped on the upper edge of the European slot of the window sash, so as to realize the installation and positioning function of the upper hinge and the window sash.

[0076] In the present application, the flat opening and the inward turning of the hinge are driven by rotating the window handle direction. How to realize it is the content of the prior art. The present application is not a solution to how the handle controls the state of the hinge, but only provides a kind of hinge for installation between the window sash and the window frame, which ensures that the window has good connection and can rotate relatively when the window is flat, inward or closed.
