[0002] A hinge is a mechanical device used to connect two solid objects and allow them to rotate relative to each other. A hinge can be made of movable components or foldable materials. A rebound hinge is a hinge that can automatically return to its original position after rotation.

[0003] However, it still has the following disadvantages in actual use:

[0004] When using existing rebound hinges, a torsion spring is usually used to achieve a rebound effect for the hinge. However, the elastic force generated when the torsion spring is compressed is fixed, and the rebound speed of the rebound hinge cannot be controlled, resulting in the rebound effect of the rebound hinge not being able to rebound according to personal needs, which is inconvenient to use.

[0032] See also Figure 1-3 As shown, this embodiment is a speed-controllable rebound hinge, comprising:

[0033] Hinge assembly 1; Hinge assembly 1 includes hinge leaf 11;

[0034] The rebound assembly 2 comprises a fixed box 21 fixedly connected to the central position of the upper end of the hinge leaf 11 on one side, a rotating rod 22 rotatably connected to the inner position of the fixed box 21, a fixing nut 23 threadedly connected to the upper end of the rotating rod 22, a traction rope 24 fixedly connected to the central outer surface of the rotating rod 22, a movable disk 25 fixedly connected to the other end of the traction rope 24, a sleeve 26 fixedly connected to the central position of the upper end of the hinge leaf 11 on the other side, and a first telescopic spring 27 fixedly connected to the central position of the upper end of the movable disk 25;

[0035] The fixing box 21 is used to support the rotating rod 22, the rotating rod 22 is used to drive the traction rope 24 to move, the fixing nut 23 is used to fix the rotating rod 22, the traction rope 24 is used to drive the movable disk 25 to move, the movable disk 25 is used to drive the first telescopic spring 27 to be compressed, and the sleeve 26 is used to support the movable disk 25 and the first telescopic spring 27;

[0036] The hinge assembly 1 further includes fixing holes 12 formed at both sides of the upper end of the hinge leaf 11 and a rotating shaft 13 fixedly connected to the central position of the hinge leaf 11;

[0037] The fixing hole 12 is used to fix the hinge leaf 11, and the rotating shaft 13 is used to drive the hinge leaf 11 to rotate;

[0038] The side surface of the fixing box 21 and the top of the sleeve 26 are respectively provided with through holes opened relative to the traction rope 24, and the traction rope 24 is wrapped around the central outer surface position of the rotating rod 22;

[0039] When the rotating rod 22 is rotated clockwise, the traction rope 24 is rotated and driven to be wound around the central outer surface of the rotating rod 22. When the rotating rod 22 is rotated counterclockwise, the traction rope 24 is rotated and separated from the central outer surface of the rotating rod 22.

[0040] The sleeve 26 has a hollow structure inside that is opened relative to the movable disk 25, and the upper end of the first telescopic spring 27 is fixedly connected to the upper end position inside the sleeve 26;

[0041] The movable disk 25 can move up and down inside the sleeve 26, and when the movable disk 25 moves upward, it drives the first telescopic spring 27 to be compressed;

[0042] One end of the traction rope 24 is located inside the first telescopic spring 27, and the upper end of the rotating rod 22 passes through the fixing box 21 and extends outward;

[0043] The outer surface of the upper end of the rotating rod 22 has a thread structure opened relative to the fixing nut 23;

[0044] Working principle: when the hinge leaf 11 rotates outward, since the position of the rotating rod 22 is fixed, one end of the traction rope 24 and the movable disk 25 remain fixed, and the rotation of the hinge leaf 11 drives the sleeve 26 to rotate outward. The outward rotation of the sleeve 26 compresses the first telescopic spring 27, and the first telescopic spring 27 is compressed to generate elastic force. When the rotational force applied to the hinge leaf 11 stops, the hinge leaf 11 rebounds under the elastic force of the first telescopic spring 27. At this time, by rotating the rotating rod 22, one end of the traction rope 24 is wrapped around the central outer surface position of the rotating rod 22. The movement of the traction rope 24 drives the movable disk 25 to move. The movement of the movable disk 25 drives the first telescopic spring 27 to be compressed, thereby changing the elastic force of the first telescopic spring 27, thereby changing the rebound speed of the hinge leaf 11.

[0045] See also Figure 4 As shown, this embodiment is based on the above embodiment and also includes:

[0046] The movable component 3 is fixedly connected to the fixing box 21 and the bottom end of the sleeve 26;

[0048] The fixed block 31 is used to support the fixed box 21 and the sleeve 26, the second telescopic spring 32 is used to support the movable plate 33, the movable plate 33 is used to drive the support block 34 to support, and the support block 34 is used to drive the movable plate 33 to move;

[0049] The two ends of the fixed block 31 have hollow structures opened relative to the movable plate 33 and the support block 34, and the upper end of the support block 34 exceeds the upper end of the fixed block 31.

[0050] When the support block 34 drives the movable plate 33 to move inward, the movable plate 33 drives the second telescopic spring 32 to be compressed;

[0051] Working principle: When the rebound component 2 needs to be installed, an inward force is applied to the support block 34, so that the movable plate 33 moves inward under the drive of the support block 34, and the second telescopic spring 32 is compressed under the drive of the movable plate 33, and then the fixed block 31 is placed inside the hinge page 11. At this time, the force applied to the support block 34 is stopped, and the movable plate 33 moves outward under the elastic force of the second telescopic spring 32. When the movable plate 33 moves to the inside of the hinge page 11, the installation of the rebound component 2 is completed, and the disassembly principle is the same as above.
