DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figure 1-3 In this embodiment, a hidden quick-install furniture link comprises a side panel 1, a back panel 2 is fixedly connected to the back of the side panel 1, a top panel 3 is fixedly connected to the right side of the side panel 1, a bottom panel 4 is fixedly connected to the right side of the side panel 1, and a hinge structure 5 is arranged on the top of the bottom panel 4;

[0020] The hinge structure 5 includes a fixed column 501, a rotating plate 502, a threaded groove 503, a threaded column 504, a fixed plate 505, a movable plate 506, a slider 507, a slide groove 508, a spring 509, a limit column 5010, a hinge seat 5011, a rotating rod 5012, a bump 5013 and a connecting shell 5014. The top of the bottom plate 4 is fixedly connected with the fixed column 501, the rotating plate 502 is sleeved on the outside of the fixed column 501, the right side of the rotating plate 502 is provided with a threaded groove 503, the inside of the threaded groove 503 is provided with a threaded column 504, the right side of the threaded column 504 is fixedly connected with the fixed plate 505, and the fixed plate 505 is fixedly connected to the fixed plate 505. Two movable plates 506 are arranged on the right side, and sliders 507 are fixedly connected to the left sides of the two movable plates 506. Two sliding grooves 508 are opened on the right side of the fixed plate 505, and springs 509 are fixedly connected to the opposite surfaces of the two sliders 507. A limiting column 5010 is fixedly connected to the right side of the fixed plate 505. The opposite surfaces of the two movable plates 506 are fixedly connected to hinge seats 5011, and the opposite surfaces of the two hinge seats 5011 are hinged with rotating rods 5012. The separated surfaces of the two movable plates 506 are fixedly connected to two protrusions 5013, and a connecting shell 5014 is arranged on the right side of the fixed plate 505.

[0021] In the case implementation, when one of the two springs 509 fails and the movable plate 506 needs to move, the other movable plate 506 cannot move due to the resistance of the spring 509, the rotating rod 5012 cannot rotate, and the movable plate 506 cannot move. Even if one of the springs 509 fails, the stability of the connection can be guaranteed.

[0022] In the case implementation, since the side panels 1 and the back panel 2 are both outside the door frame, only a small part of the top panel 3 and the bottom panel 4 and the fixing column 501 remain outside, and the connecting shell 5014 is inside the door, ensuring the invisible beauty.

[0023] In the case implementation, when the rotating plate 502 rotates, it is affected by the side plate 1 and the back plate 2 and can only rotate ninety degrees, which limits the rotation range of the door.

[0024] When implementing, follow these steps:

[0025] 1) First, put the side plate 1 and the back plate 2 into the door frame, the rotating plate 502 can be rotated 90 degrees, and the threaded column 504 is rotated to enter the threaded groove 503, and the two movable plates 506 are on the same horizontal plane;

[0026] 2) Then, the two moving plates 506 are pressed to move toward opposite sides, the two springs 509 are contracted, the rotating rod 5012 is rotated, and the connecting shell 5014 is placed inside the door;

[0027] 3) Finally, the two movable plates 506 are placed into the interior of the connecting shell 5014. The elastic force of the spring 509 drives the two movable plates 506 to move toward the separated surfaces, and the protrusion 5013 enters the limiting groove.

[0028] In summary, the invisible quick-install furniture link, by setting a hinge structure 5, the side panel 1 and the back panel 2 are placed into the interior of the door frame, the rotating plate 502 can be rotated ninety degrees, the threaded column 504 is rotated to make it enter the threaded groove 503, the two movable plates 506 are on the same horizontal plane, the two movable plates 506 are pressed to move to opposite sides, the two springs 509 are contracted, the rotating rod 5012 is rotated, the connecting shell 5014 is placed into the interior of the door, the two movable plates 506 are placed into the interior of the connecting shell 5014, the elastic force of the spring 509 drives the two movable plates 506 to move toward the separated surfaces, and the protrusion 5013 enters the limiting groove, which solves the problem that the installation of the link is usually cumbersome, time-consuming, and not beautiful after installation, affecting the visual appearance.
