AI Technical Summary
The existing sliding rail structure of casement window hinges is insufficient in terms of load-bearing capacity and wind resistance, making it difficult to meet the needs of heavy-duty window sashes.
A sliding rail component was designed, including an indoor A-side and an outdoor B-side, both of which are 7-shaped. The A-side is higher than the B-side. The slider slides in the groove. The increased A-side improves the load-bearing capacity and wind resistance, and the limiting block and opening structure enhance stability and cleanliness.
The increased load-bearing capacity and wind resistance of the sliding rails prevent the sliders from loosening, ensuring the stability of the window sash, while also facilitating cleaning and enhancing the overall structural durability.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of hinges, and more particularly to a casement window hinge. Background Technology
[0002] Hinges, also called sliding supports, are one of the main components of casement windows. Common casement window hinges include a slide rail fixed to the window frame and a fixing strip fixed to the window sash. A slider is slidably mounted on the slide rail, and a connecting rod connected to the fixing strip is mounted on the slider. Referring to the invention patent with publication number CN107558839B and the patent title "A Casement Window Fixed Hinge", most existing slide rails are C-shaped, that is, from the end face, they include a horizontally placed flat plate and hooked edges symmetrically arranged on both sides of the flat plate, thus forming a groove for the slider to slide. However, as casement window sashes are becoming heavier and heavier, such slide rail structures are insufficient in load-bearing capacity and wind resistance. Therefore, how to improve the load-bearing capacity and wind resistance of slide rails is a problem that technicians need to solve. Utility Model Content
[0003] The present invention provides a casement window hinge to solve the aforementioned problems.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a casement window hinge, comprising a hinge, the hinge comprising a slide rail and a slider, the slide rail comprising a flat plate, the flat plate having an a-edge on the indoor side and a b-edge on the outdoor side, thereby forming a sliding groove, the slider being slidably connected to the sliding groove, the a-edge and the b-edge both being in the shape of a "7", and the a-edge being higher than the b-edge.
[0005] Furthermore, both the a-side and the b-side include vertically arranged columns on both sides of the plate, and the top of the vertical column is bent inward to form a horizontal column.
[0006] Furthermore, the slider is close to the two vertical columns on both sides, and a top is provided on one side of the top of the slider, which is located inside the a-side block. A notch is recessed on the other side, and the horizontal column of the b-side block is located inside the notch.
[0007] Furthermore, a limiting block for abutting the slider is provided on the upper side of the plate.
[0008] Furthermore, the b-edge is provided with an opening.
[0009] Furthermore, the slide rail component is provided with mounting holes.
[0010] Compared with the prior art, the beneficial effects of this utility model are: by setting the slide rail component and by setting the raised a-stop edge on the indoor side of the slide rail component, the load-bearing capacity and wind resistance are improved compared with the existing slide rail component structure.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] As shown in the attached figure, this utility model discloses a casement window hinge. The hinge includes a slide rail 1 and a slider 2, as well as a window sash fixing strip 30 and multiple connecting rods. The window sash fixing strip 30 is movably connected to the slider 2 and the slide rail 1 through multiple connecting rods. The slide rail 1 is integrally formed and includes a flat plate 10. The flat plate 10 has an a-edge 11 on the indoor side and a b-edge 12 on the outdoor side, thereby forming a sliding groove 100. The slider 2 is slidably connected to the sliding groove 100. Both the a-edge 11 and the b-edge 12 are in the shape of a "7", and the a-edge 11 is higher than the b-edge 12. By setting the slide rail 1 and the raised a-edge 11 on the indoor side of the slide rail 1, the load-bearing capacity and wind resistance are improved compared with the existing slide rail 1 structure.
[0018] Specifically, both the a-edge 11 and the b-edge 12 include vertical columns arranged on both sides of the plate 10, and the top of the vertical column is bent inward to form a horizontal column.
[0019] Specifically, the slider 2 is close to the two vertical sections on both sides, that is, the indoor side of the slider 2 is close to the a-edge 11 and the outdoor side is close to the b-edge 12. The top of the slider 2 is provided with a top 21 on one side, which is located inside the a-edge 11. The other side is recessed with a notch 22. The horizontal section of the b-edge 12 is located inside the notch 22. The indoor side uses the a-edge 11 to abut against the top 21, and the outdoor side uses the b-edge 12 to abut against the notch 22, so as to prevent the slider 2 and the slide groove 100 from loosening and causing the window sash to sag when the hinge is opened.
[0020] Specifically, a limiting block 102 is provided on the upper side of the plate 10 to abut against the slider 2, thereby limiting the slider 2 and preventing it from sliding excessively.
[0021] Specifically, the b-edge 12 has an opening 120, which facilitates cleaning dust from the slide rail 100. This opening 120 can also be fitted with a drain corresponding to the window frame. The slide rail 1 has mounting holes 1000 for connecting hinges and the window frame.
[0022] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
