Description

Technical Field

[0001] The utility model relates to the technical field of window hinges, in particular to a heavy-duty dustproof hinge that opens outwards at 90 degrees. Background Art

[0002] Windows usually use hinges or hinges to open and close, while outward-opening windows are opened and closed by hinges, which are installed on the window frame and use several interconnected rods to open the window and maintain the required angle.

[0003] In the related technology, a solution of a window hinge (Announcement No. CN220133754U) was found through searching, in which a sliding shaft slides on a sliding hole along the direction of a first fixed hinge cross plate to adjust the lateral position of the window frame, so that the window can be adjusted laterally after it is opened, and the diversity of the opening directions of the window can be adjusted.

[0004] However, the resistance of the above-mentioned traditional hinges is generally achieved by riveting to increase the damping of the hinge rotation, thereby achieving the resistance to window opening and closing. In this way, as the window opening and closing increases, the resistance of the hinge will decrease after wear. At this time, the window's ability to resist wind will be reduced, and the problem of the window hitting the window frame will occur; and the hinge wear is prone to metal friction noise, and creaking noise will occur when the window is opened and closed. Utility Model Content

[0007] The gasket can reduce the friction between the first connecting member, the second connecting member and the base member, thereby reducing the wear between these components;

[0008] A sliding groove is provided on the left side of the surface of the base member, and a movable block and a clamping block are provided on both sides of the base member, and the movable block and the clamping block clamp the base member, and a sliding adjustment screw threadedly connected with the clamping block is inserted into the surface of the movable block, and the movable block is slidably connected with the sliding groove. Turning the sliding adjustment screw can change the sliding resistance of the movable block, realize the adjustment of the hinge damping, and then change the resistance of opening and closing the window;

[0009] The surface of the movable block is rotatably connected to a telescopic rod, the middle part of the telescopic rod is rotatably connected to the first connecting piece, the second connecting piece is rotatably connected to a swing arm, the middle part of the swing arm is rotatably connected to the telescopic rod, so that the hinge can rotate smoothly and stably support the window.

[0010] Furthermore, the surfaces of the telescopic rod, the first connecting member and the second connecting member are provided with convex grooves, and the bearing capacity of the hinge can be improved through the convex grooves, ensuring that the hinge will not be deformed during use.

[0011] Furthermore, the base member and the telescopic rod are provided with a first mounting hole and a second mounting hole on their surfaces, respectively, and the first mounting hole and the second mounting hole facilitate the connection between the base member and the window frame, and also facilitate the connection between the telescopic rod and the window.

[0012] Furthermore, a top head is fixedly connected to the right end of the base member, and the top head is used to facilitate the hinge to rest against the window frame.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) By turning the sliding adjustment screw, the clamping force of the movable block and the clamping block on the base member can be changed, thereby changing the sliding resistance of the telescopic rod.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example:

[0022] See also Figure 1-2 The utility model provides a technical solution: a heavy-duty dustproof hinge with an outward opening of 90°, comprising a base member 2, a gasket 10 connected to the surface of the base member 2, a first connecting member 8 and a second connecting member 9 rotatably connected to the left and right sides of the surface of the gasket 10, the first connecting member 8 and the second connecting member 9 are riveted to the gasket 10 and the base member 2, so that the gasket 10 is connected to the base member 2, and the gasket 10 helps to increase the thickness of the base member 2, improve the bearing capacity of the base member 2, prevent the deformation of the base member 2, and ensure that there is no eccentric wear when the hinge rotates;

[0023] The left side of the surface of the base member 2 is provided with a sliding groove 6, and the two sides of the base member 2 are provided with a movable block 3 and a clamping block 16, and the movable block 3 and the clamping block 16 clamp the base member 2, and the surface of the movable block 3 is inserted with a sliding adjustment screw 7 threaded with the clamping block 16, and the movable block 3 is slidably connected with the sliding groove 6. Turning the sliding adjustment screw 7 can control the clamping force of the movable block 3 and the clamping block 16 on the base member 2, thereby changing the hinge rotation resistance. When the resistance is increased, the wind resistance of the window can also be improved;

[0024] The surface of the movable block 3 is rotatably connected to a telescopic rod 4, the middle part of the telescopic rod 4 is rotatably connected to a first connecting piece 8, the second connecting piece 9 is rotatably connected to a swing arm 1, the middle part of the swing arm 1 is rotatably connected to the telescopic rod 4, the first connecting piece 8 and the second connecting piece 9 are used to support and limit the swing arm 1, ensuring that the swing arm 1 is more stable when rotating.

[0025] In this embodiment, if Figure 1 and Figure 2 As shown, the surfaces of the telescopic rod 4, the first connecting member 8 and the second connecting member 9 are provided with convex grooves 15, and the convex grooves 15 improve the bearing capacity of the telescopic rod 4, the first connecting member 8 and the second connecting member 9 to support the heavier windows stably.

[0026] In this embodiment, if Figure 2 As shown, a reinforcing sheet 13 is fixedly connected to the surface of the telescopic rod 4, and the reinforcing sheet 13 is rotatably connected to the second connecting member 9. The reinforcing sheet 13 increases the thickness of the swing arm 1 to prevent the swing arm 1 from being worn when the first connecting member 8 rotates.

[0027] In this embodiment, if Figure 1 As shown, the surfaces of the base member 2 and the telescopic rod 4 are respectively provided with a first mounting hole 5 and a second mounting hole 14, and screws are used to match the first mounting hole 5 and the second mounting hole 14 so that the hinge is connected to the window.

[0028] In this embodiment, if Figure 1 As shown, a fixing tube 11 is inserted into the surface of the gasket 10, and the fixing tube 11 is connected to the base member 2. The use of the fixing tube 11 can improve the stability of the connection between the gasket 10 and the base member 2, ensuring that the gasket 10 will not loosen and the hinge will not make abnormal noise when rotating.

[0029] In this embodiment, if Figure 1 As shown, the right end of the base member 2 is fixedly connected with a top head 12. After the hinge is installed on the window, the top head 12 can support the window frame to prevent the hinge from loosening.

[0030] Specifically, when in use, the base member 2 is connected to the window frame using screws in conjunction with the first mounting hole 5, and the swing arm 1 is connected to the window sash using screws in conjunction with the second mounting hole 14. The sliding resistance of the movable block 3 is changed by turning the sliding adjustment screw 7. When the window sash is opened and closed, the window sash drives the swing arm 1 to rotate, and the first connecting member 8 and the second connecting member 9 follow the rotation. The gasket 10 can prevent the first connecting member 8 and the second connecting member 9 from wearing the base member 2, thereby improving the durability of the hinge. When the resistance of the movable block 3 decreases due to wear, the sliding adjustment screw 7 is turned to increase the resistance, thereby maintaining the resistance of the window sash opening and closing. When the wind blows the window sash, the window sash is prevented from hitting the window frame, which is safer.
