Window hinge, fabrication method for window hinge and window with window hinge

Abstract

The invention relates to a window hinge. The window hinge comprises a sliding way, a pulling rod, a hinge fixing part fixed to one end of the sliding way and a slideable part installed in the sliding way. The pulling rod is fixed to the slideable part through a connecting part; the pulling rod performs angular movement relative to the sliding way when sliding on the slideable part; when the pulling rod and the sliding way are in a closed state, the pulling rod abuts against the hinge fixing part; the hinge fixing part comprises a first face, a second face and a third face; a first included angle is formed between the first face and the second face; the third face is horizontally arranged and approximately perpendicular to the first face or the second face; the third face is provided with a first protruding part; a second protruding part is disposed on the bottom surface of the sliding way. The second protruding part is fixed in the first protruding part, so that the fixing strength of the hinge fixing part on the sliding way is increased.

Description

technical field [0001] The invention relates to a hinge structure and a manufacturing method of the structure, in particular to a window hinge and a manufacturing method thereof. Background technique [0002] In recent years, the American-style plastic door and window system has inherited the advantages of European-style doors and windows. For the window, the sash can be opened or closed from the position in contact with the window frame, and more specifically, the sash can wrap around the window frame at a certain angle. The edge is turned under the action of external force and the number of times, so as to open or close the window sash. However, the sash and the window frame are directly connected by hinges. [0003] see figure 1 A common window hinge includes a slide rail 10 fixed on the window frame, a pull rod 20 fixed on the sash, a slide part 101 installed in the slide rail 10 and slidable, and one end is rotatably fixed on the slide part 101, The other end is rota...

AI Technical Summary

Problems solved by technology

However, in the production process, since the dimensional accuracy of the pull rod 20 is not high, there is no strict requirement on the angle of the triangle point during manufacture, so some products appear. In the process of closing the pull rod 20 and the slide rail 10, The edge of the triangular point scrapes against the edge of the vertical plane of the hinge fixing part 60, so that the pull rod 20 cannot be completely closed, which affects the use

[0005] see Figures 2 to 4 , wherein the hinge fixing part 60 has two vertical surfaces 601 at an angle, and a horizontal surface 602 riveted in the slide rail by stamping. Hole 603 is opened on the top, and then a part of the bottom surface of slide rail 10 is punched into this hole 603 by a punching machine, so that the fixing method is still relatively firm, but because the protrusion 604 punched into the hole 603 by the punching machine has an arc-shaped edge 605 , after opening and closing the window hinge tens of thousands of times, the protrusion 604 with the arc-shaped edge 605 may shake in the hole 603 and affect the use, and even fall off from the hole, resulting in the window hinge can not be used
