[0020] This utility model provides a quick-installation double-sided folding sofa hinge, including a hinge shaft 101 and a folding mechanism 102. The folding mechanism 102 includes a first hinge plate 103, a second hinge plate 104, an angle adjustment component 105, and a reset component 106. The first hinge plate 103 includes a first plate body 107, multiple first mounting plates 108, and a first back plate 109. The second hinge plate 104 includes a second plate body 110, multiple second mounting plates 111, and a second back plate 112. The angle adjustment component 105 includes an angle adjustment rod 113 and multiple limiting teeth 114. The reset component 106 includes a reset block 115 and a reset spring 116.

[0021] In this specific embodiment, the first back plate 109 is fixedly connected to the first plate body 107, each of the first mounting plates 108 is fixedly connected to the first plate body 107, the first plate body 107 is fixedly connected to the hinge shaft 101, the second back plate 112 is fixedly connected to the second plate body 110, each of the second mounting plates 111 is fixedly connected to the second plate body 110, the second plate body 110 is rotatably connected to the hinge shaft 101, each of the limiting teeth 114 is fixedly connected to the angle adjusting rod 113, the angle adjusting rod 113 is rotatably connected to the first back plate 109, one end of the return spring 116 is fixedly connected to the angle adjusting rod 113, and the other end of the return spring 116 is connected to the return block 115. The reset block 115 is fixedly connected to the first plate 107. The first hinge plate 103 and the second hinge plate 104 are each provided with multiple first mounting plates 108 and second mounting plates 111, providing users with more installation options and realizing double-sided installation. The second mounting plate 111 can rotate freely around the hinge axis 101 and is connected through the angle adjustment rod 113 in the angle adjustment assembly 105. The reset spring 116 in the reset assembly 106 resets the angle adjustment rod 113, facilitating the smooth reset of the second plate 110. This design is convenient to use and solves the problems of low folding installation efficiency and limited installation contact surface with the sofa surface, which makes it inconvenient to use.

[0022] The first back plate 109 is located on the back side of the first plate body 107, and each first mounting plate 108 is located above the first plate body 107. The first plate body 107 is located above the hinge shaft 101. The second back plate 112 is located on the back side of the second plate body 110, and each second mounting plate 111 is located above the second plate body 110. The second plate body 110 is located above the hinge shaft 101. The second plate body 110 moves in a circular motion around the hinge shaft 101. The operation is convenient and simple, requiring only manual operation by the user. The arrangement of multiple first mounting plates 108 and second mounting plates 111 facilitates the operation of the first... The fixing of plate 107 and the second plate 110, compared with the existing folding sofa hinges, can achieve bidirectional installation support. The inner side of the angle adjustment rod 113 is hollow and has multiple movable teeth, the same number as the limiting teeth 114. When the user rotates the second plate 110, the movable teeth elastically retract according to the movement of the angle adjustment rod 113, ensuring that the angle adjustment rod 113 and each of the limiting teeth 114 pass smoothly through the inner side of the second back plate 112. It should also be noted that a limiting baffle is provided at the outer end of the angle adjustment rod 113, which can prevent the second plate 110 from disengaging from the angle adjustment rod 113 when the user rotates the second plate 110.

[0023] Secondly, each of the limiting teeth 114 is located on one side of the angle adjusting rod 113, which is located inside the first back plate 109. One end of the reset spring 116 is located on one side of the angle adjusting rod 113, and the other end of the reset spring 116 is located above the reset block 115, which is located on the back side of the first plate 107. Both the first back plate 109 and the second back plate 112 are hollow and have a central shaft, which is fixed to the corresponding first plate and second plate 110. One end of the angle adjusting rod 113... The end rotates around the central axis inside the first back plate 109. The angle adjustment rod 113 has one end with the limiting tooth 114, which moves against the other central axis. When the user manually pulls the first plate 107 and the second plate 110, each of the limiting teeth 114 can pass through the central axis on the back side of the second plate 110. During the reset process of the first plate 107 and the second plate 110, the reset spring 116 pulls the angle adjustment rod 113 to ensure that the limiting tooth 114 will not move against the second back plate 112 on the back side of the second plate 110.

[0024] In this embodiment, the second plate 110 rotates around the hinge axis 101, making operation convenient and simple, requiring only manual operation by the user. The arrangement of multiple first mounting plates 108 and second mounting plates 111 facilitates the fixing of the first plate 107 and the second plate 110. Compared with existing folding sofa hinges, it can achieve bidirectional installation support. The inner side of the angle adjustment rod 113 is hollow and has multiple movable teeth, the same number as the limiting teeth 114. When the user rotates the second plate 110, the movable teeth elastically retract according to the movement of the angle adjustment rod 113, ensuring that the angle adjustment rod 113 and each of the limiting teeth 114 pass smoothly through the inner side of the second back plate 112. It should also be noted that a limiting baffle is provided at the outer end of the angle adjustment rod 113 to prevent the user from rotating the second plate 110. The second plate 110 disengages from the angle adjustment rod 113. Both the first back plate 109 and the second back plate 112 are hollow and have a central shaft fixed to the corresponding first plate and second plate 110. One end of the angle adjustment rod 113 rotates around the central shaft inside the first back plate 109. One end of the angle adjustment rod 113 with the limiting tooth 114 moves against the other central shaft. When the user manually pulls the first plate 107 and the second plate 110, each limiting tooth 114 can pass through the central shaft on the back side of the second plate 110. During the reset process of the first plate 107 and the second plate 110, the reset spring 116 pulls the angle adjustment rod 113 to ensure that the limiting tooth 114 does not move against the second back plate 112 on the back side of the second plate 110.

[0025] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
