Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a load-bearing hinge. Background Art

[0002] Casement windows are a common type of window, named because the window sash moves in a horizontal direction when it opens and closes. Casement windows can be fully opened, allowing for more adequate indoor air circulation and better ventilation. Casement windows are usually composed of window frames, window sashes, hinges and other components. The hinges are installed on both sides of the window sashes and connected to the window frame. They are the key components that support the window sashes and ensure that the window can be opened flexibly. Referring to the hinge structure of a casement window with the publication (announcement) number CN218407018U, we know that in the early days, in order to increase the load-bearing performance of the hinge, our company would connect the hinges to the window frame. A load-bearing plate is set at the bottom of the plate, which uses the load-bearing plate to improve the overall load-bearing capacity of the hinge, effectively solving the problem of easy sagging of the window sash and improving the wind resistance. The current hinge load-bearing plate is installed at the bottom of the window frame connecting plate, and supports the window sash through multiple connecting rods hinged on the window frame connecting plate. However, in such a hinge structure, the load-bearing plate and the window frame are connected on one side, and in actual application, only one side is stressed, and its stress surface is small. Long-term use in high-rise buildings or other environments with high wind pressure will still cause the window sash to "fall off the corner", posing a safety hazard. Therefore, the load-bearing performance of the hinge still needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] As shown in the accompanying drawings, the utility model is a load-bearing hinge. The overall structure of the casement window includes an openable window sash and a window frame. The window frame is composed of two vertical profiles 41 and two horizontal profiles 42. A window sash is generally installed with two hinges. The two hinges are respectively arranged at the corresponding ends of the top and bottom of the window sash. The window frame connecting plates 1 of the two hinges are respectively connected to the two horizontal profiles 42 at the top and bottom of the window frame. This belongs to the existing casement window hinge installation structure. It should be noted that the hinge includes a window frame connecting plate 1 and connecting rod 3, the window frame connecting plate 1 is provided with a load-bearing plate 2, the load-bearing plate 2 is L-shaped, and includes a vertical portion 21 and a horizontal portion 22 formed by bending, the horizontal portion 22 is arranged at the bottom of the window frame connecting plate 1, the vertical portion 21 is located at one end of the window frame connecting plate 1, and protrudes upward from the window frame connecting plate 1, the vertical portion 21 and the horizontal portion 22 are perpendicular to each other, wherein the vertical portion 21 is used to connect the window frame vertical column profile 41, and the horizontal portion 22 is used to connect the window frame horizontal column profile 42.

[0021] The utility model provides a load-bearing hinge, which is provided with an L-shaped load-bearing plate 2, the horizontal portion 22 of which is located at the bottom of the window frame connecting plate 1, and is used to cooperate with the window frame horizontal profile 42 to bear force, and the vertical portion 21 is located at one end of the window frame connecting plate 1, and is used to cooperate with the window frame vertical profile 41 to bear force, thereby increasing the load-bearing surface between the hinge and the window frame. By changing the hinge structure, the load-bearing performance of the hinge is improved, so that it can support the window sash more stably and reduce safety hazards. It is preferred to use a material with higher hardness such as steel to make the load-bearing plate 2.

[0022] In this embodiment, the window frame includes a vertical profile 41 and a horizontal profile 42, and the vertical profile 41 and the horizontal profile 42 are both provided with a mounting groove 400. This belongs to the existing casement window structure and will not be described in detail here. It should be noted that the vertical portion 21 is arranged in the mounting groove 400 of the vertical profile 41, and the width of the load-bearing plate 2 corresponds to the width of the mounting groove 400. The horizontal portion 22 is arranged in the mounting groove 400 of the horizontal profile 42, and the vertical portion 21 and the horizontal portion 22 are clamped by the side walls of the mounting groove 400, which is more conducive to the installation of the hinge and the window frame. When the window sash is open, the overall pressure is inclined toward the opening direction of the window sash. Since the vertical portion 21 is fixedly connected to the vertical profile 41 and the horizontal portion 22 of the window frame 2 The horizontal profile 42 fixedly connected to the window frame realizes multi-faceted force between the hinge and the window frame, and the width of the mounting groove 400 corresponds to the width of the load-bearing plate 2. With the help of the existing mounting groove 400 structure, the load-bearing plate 2 is pressed against the window sash to provide more stable support. The thickness of the load-bearing plate 2 corresponds to the depth of the mounting groove 400. Preferably, the thickness of the load-bearing plate 2 is equal to or less than the depth of the mounting groove 400, so that the load-bearing plate 2 does not protrude from the window frame, better connecting the load-bearing plate 2 and the window frame, and ensuring the normal use of the hinge. If the thickness of the load-bearing plate 2 is less than the depth of the mounting groove 400, that is, there is a gap between the bottom of the horizontal portion 22 and the bottom of the mounting groove 400, the window frame connecting plate 1, the horizontal portion 22 and the window frame horizontal profile 42 can be tightened by fixing screws.

[0023] In this embodiment, the connecting rod 3 passes through the window frame connecting plate 1 through the rivet 33 and is riveted to the load-bearing plate 2, that is, the rivet 33 is not connected to the window frame connecting plate 1, and a through hole is provided on the window frame connecting plate 1. The rivet 33 on the connecting rod 3 passes through the through hole and is riveted to the load-bearing plate 2.

[0024] In this embodiment, a positioning card 11 is rotatably provided at the bottom of the window frame connecting plate 1 and at one end away from the load-bearing plate 2. The structure of the positioning card 11 belongs to the prior art. It should be noted that the positioning card 11 is rotatably connected to the bottom of the window frame connecting plate 1. The positioning card 11 is mainly used to assist in the installation of the hinge. When connecting the hinge and the window frame, the hinge can be placed in the window frame first so that the load-bearing plate 2 is located in the installation groove 400, and the positioning card 11 is rotated. The positioning card 11 is connected to the installation groove 400 of the window frame to temporarily fix the hinge to the window frame. At this time, the hinge and the window frame are fixed with screws. The center lines of the window frame connecting plate 1 and the load-bearing plate 2, as well as the rotation center of the positioning card 11 are all set on the same straight line, that is, Figure 4 As shown, along the width direction of the window frame connecting plate 1, the center line of the window frame connecting plate 1, the center line of the load-bearing plate 2, and the rotation point of the positioning card 11 are all located on the same straight line, making the overall appearance of the hinge more beautiful and ensuring the force balance of the hinge structure.

[0025] In this embodiment, the vertical portion 21 is provided with a first mounting hole 211, and the window frame connecting plate 1 is provided with a second mounting hole 222 that extends through the horizontal portion 22. Screws are inserted through the first and second mounting holes 211, 222, and fixedly connected to the window frame profile, making the connection between the load-bearing plate 2 and the window frame more stable. More specifically, the first mounting hole 211 is provided at one end of the vertical portion 21 near the top, and when the hinge is installed on the window frame, the height of the first mounting hole 211 is higher than the height of the window frame angle bracket, preventing the screw from driving into the window frame angle bracket. The load-bearing plate 2 is an integrally formed structure. The integrally formed load-bearing plate 2 has higher strength, can further improve the load-bearing performance of the hinge, and is convenient for production of the load-bearing plate 2.

[0026] The above embodiments are preferred embodiments of the present invention. All structures similar to those of the present invention and equivalent changes made thereto should fall within the scope of protection of the present invention.
