Description

Technical Field

[0001] The utility model relates to the technical field of window hinges, in particular to a window hinge capable of fixing an angle. Background Art

[0002] Window hinges, also known as hinges, are an important part of window hardware accessories. Its main function is to ensure that the window can be opened and closed smoothly, while bearing the weight of the window and reducing noise and friction.

[0003] At present, the opening and closing angles of most window hinges are controlled by limiting the plastic parts at the bottom of the mounting plate. After long-term use, the plastic parts are prone to aging and affect normal use. When the mounting plate is connected to the fixed outer frame, the plastic parts are placed between the fixed outer frame and the mounting plate. It is inconvenient for users to adjust the opening and closing angles of the window hinges according to their own needs. At this time, professional staff are required to remove the movable sash and window hinges together and replace the window hinges. This process is not only time-consuming and labor-intensive, but also requires professional staff to perform disassembly and assembly operations, and the adjustment cost is high. Utility Model Content

[0004] The purpose of the utility model is to provide a window hinge with a fixed angle to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a window hinge capable of fixing an angle, comprising a mounting plate, and further comprising:

DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1-5 As shown, a window hinge with a fixed angle comprises a mounting plate 1, a slide groove 2 and a guide groove 3 are provided on the top of the mounting plate 1, a support plate 4 is hinged on the top of the mounting plate 1, a transverse plate 6 is hinged on one side of the top of the support plate 4, a bending plate 7 is rotatably connected to the top of the support plate 4, a connecting frame 5 is hinged on one side of the top of the bending plate 7, one side of the top of the transverse plate 6 is hinged to the bottom of the connecting frame 5, a sliding rod 8 is rotatably penetrated through the top of the bending plate 7, the surface of the sliding rod 8 is in contact with the inner wall of the slide groove 2, a movable plate 9 is fixedly sleeved below the surface of the sliding rod 8, an adjusting mechanism 10 is installed on the top of the movable plate 9, positioning columns 12 are fixedly penetrated on both sides of the top of the mounting plate 1, and two positioning columns 12 are respectively arranged on both sides of the guide groove 3.

[0023] The adjusting mechanism 10 comprises an adjusting shaft 101, a disc 102 and a stop plate 103. The surface of the adjusting shaft 101 contacts the inner wall of the guide groove 3. The disc 102 is fixedly connected to the top of the adjusting shaft 101. The stop plate 103 is fixedly connected to the bottom of the adjusting shaft 101. The bottom of the disc 102 contacts the top of the mounting plate 1. The adjusting shaft 101 is fixedly passed through the movable plate 9. The top of the stop plate 103 contacts the bottom of the movable plate 9. The diameter of the disc 102 is greater than the width of the inner wall of the guide groove 3. A slot 11 is provided on the top of the disk 102, so that the staff can rotate the disk 102 and the adjustment shaft 101 through the slot 11, thereby driving the limit plate 103 to rotate, so as to facilitate the adjustment of the state of the limit plate 103. The surface of the limit plate 103 is in contact with the positioning column 12, and the height of the bottom of the positioning column 12 is lower than the height of the bottom of the limit plate 103. Therefore, the positioning column 12 can limit the movable range of the limit plate 103 after the state of the limit plate 103 is adjusted.

[0024] A slot 11 is formed on the surface of the bending plate 7 , and the surface of the transverse plate 6 contacts the inner wall of the slot 11 , thereby facilitating the storage and placement of the transverse plate 6 .

[0025] The length of the limit plate 103 is greater than the distance between the two positioning columns 12, and the width of the limit plate 103 is less than the distance between the two positioning columns 12. Accordingly, the limit plate 103 can pass between the two positioning columns 12 under normal conditions. When the staff adjusts the state of the adjustment mechanism 10, the positioning columns 12 can limit the movable range of the limit plate 103.

[0026] Working principle: When the window hinge is in use, the mounting plate 1 is mounted on the fixed outer frame of the window, and the connecting frame 5 is mounted on the movable sash of the window. When the user opens the movable sash, the connecting frame 5 can be unfolded, and the horizontal plate 6, the supporting plate 4 and the bending plate 7 can be unfolded accordingly, and the sliding rod 8 can drive the movable plate 9 to move. At this time, the limit plate 103 can be smoothly moved between the two positioning columns 12, and the user can unfold the movable window sash to 180 degrees;

[0027] In addition, the user can also use a tool to rotate the disc 102 through the slot 11. At this time, the adjustment shaft 101 drives the limit plate 103 to rotate 90 degrees. When the user unfolds the movable window sash again, the limit plate 103 and the positioning column 12 are used in conjunction to limit the movable range of the movable plate 9. At this time, the connecting frame 5 can drive the movable window sash to unfold to 90 degrees. Based on this, the user can adjust the unfoldable angle of the connecting frame 5 according to the needs of the unfolding angle of the movable window sash.
