Technical Field
[0001] The utility model relates to the technical field of hinges, in particular to a concealed one-way damping hinge. Background Art
[0002] A hinge is a mechanical device used to connect two solids and allow relative rotation between them. A hinge can be composed of movable components or foldable materials. Hinges are more commonly installed on cabinets and are mainly classified by material into stainless steel hinges and iron hinges.
[0003] Many modern hinges adopt a two-way torque design aimed at achieving stable control during door opening and closing. However, this design may require a relatively large force to be applied during operation, especially during the opening and closing actions, which may affect the convenience of use.
[0004] In view of the above problems, a concealed one-way damping hinge needs to be designed. Summary of the Utility Model
[0005] In order to overcome the disadvantage of inconvenient two-way torque for opening and closing doors, the utility model provides a concealed one-way damping hinge.
[0006] The technical solution of the utility model is: a concealed one-way damping hinge, including a rotating shaft, a friction washer, a moving hinge, a reinforcing piece, a spring washer, a locking nut, a one-way bearing and a static hinge. A circular ring is provided in the middle of the rotating shaft. A plurality of friction washers are slidably connected to the rotating shaft. The right friction washer is in contact with the left side surface of the circular ring on the rotating shaft. The moving hinge is slidably and rotatably connected to the rotating shaft. The moving hinge is located between the two friction washers and is in contact and cooperation with the two friction washers. The reinforcing piece is slidably connected to the rotating shaft and is in clamping cooperation with the moving hinge. The spring washer is slidably connected to the rotating shaft and is in contact and cooperation with the reinforcing piece. The locking nut is rotatably connected to the rotating shaft. The one-way bearing is rotatably connected to the rotating shaft. The left side surface of the one-way bearing is in contact and cooperation with the right side surface of the circular ring on the rotating shaft. The static hinge is clamped on the one-way bearing, and the static hinge is riveted and connected to the one-way bearing and the rotating shaft.
[0007] Further, it further includes a first anti-slip pad, and the first anti-slip pad is connected to the bottom of the moving hinge.
[0008] Further, it further includes a second anti-slip pad, and the second anti-slip pad is connected to the bottom of the static hinge.
[0009] Further, the moving hinge and the static hinge are provided with hole positions for installation.
[0010] Further, the moving hinge is arc-shaped.
[0011] Further, a plurality of U-shaped grooves are evenly spaced on the one-way bearing.
[0012] Further, there are at least two friction washers.
[0013] Further, the bumps on the reinforcing piece are the same size as the square grooves on the moving hinge.
[0014] Further, the contact part between the moving hinge and the rotating shaft is coated with a self-lubricating coating.
[0015] Further, the material of the spring washer is stainless steel.
[0016] The beneficial effects of the present utility model are as follows: When assembling this device, the installation sequence can be simplified by first installing the moving hinge and then the static hinge. When this device is in use, a constant torque can be generated when the moving and static hinges rotate relative to each other, and the one-way bearing provides one-way movement, enabling one-way movement, facilitating opening, and enhancing the service life of the hinge.

[0022] The embodiments of the present utility model will be described in detail below with reference to the drawings.
[0023] Embodiment: A concealed one-way damping hinge, as Figures 1-4As shown in the figure, it includes a rotating shaft 1, a friction washer 2, a moving hinge 3, a reinforcing piece 4, a spring washer 5, a locking nut 6, a one-way bearing 7, a static hinge 8, a first anti-slip pad 9 and a second anti-slip pad 10. A ring is provided in the middle of the rotating shaft 1. A plurality of friction washers 2 are slidably connected to the rotating shaft 1. The friction washer 2 on the right side is in contact with the left side surface of the ring on the rotating shaft 1. There are no less than two friction washers 2. A moving hinge 3 is slidably and rotatably connected to the rotating shaft 1. The moving hinge 3 is used to open and close the door. The contact part between the moving hinge 3 and the rotating shaft 1 is coated with a self-lubricating coating. The moving hinge 3 is arc-shaped. The moving hinge 3 and the static hinge 8 are provided with hole positions for installation. The moving hinge 3 is located between two friction washers 2 and is in contact and cooperation with the two friction washers 2. A reinforcing piece 4 is slidably connected to the rotating shaft 1. The reinforcing piece 4 strengthens and fixes the moving hinge 3. The reinforcing piece 4 is in snap-fit connection with the moving hinge 3. The convex block on the reinforcing piece 4 is the same size as the square groove on the moving hinge 3. A spring washer 5 is slidably connected to the rotating shaft 1. The spring washer 5 is in contact and cooperation with the reinforcing piece 4. The material of the spring washer 5 is stainless steel. A locking nut 6 is rotatably connected to the rotating shaft 1. The locking nut 6 can adjust the required constant torque. A one-way bearing 7 is rotatably connected to the rotating shaft 1. The left side surface of the one-way bearing 7 is in contact and cooperation with the right side surface of the ring on the rotating shaft 1. The rotating shaft 1 can make a one-way rotational movement relative to the static hinge 8 through the one-way bearing 7. A plurality of U-shaped grooves are evenly spaced on the one-way bearing 7. A static hinge 8 is snap-connected to the one-way bearing 7. The static hinge 8 is riveted and connected to the one-way bearing 7 and the rotating shaft 1. The bottom of the moving hinge 3 is connected with a first anti-slip pad 9. The bottom of the static hinge 8 is connected with a second anti-slip pad 10.
[0024] When the device needs to be used and assembled, the user places the friction washer 2 at the left end of the rotating shaft 1, and then pulls it to move along the rotating shaft 1. When the friction washer 2 moves to contact and fit with the left side surface of the ring on the rotating shaft 1, the friction washer 2 is then released. Then, the moving hinge 3 is placed at the left end of the rotating shaft 1, and it is pulled to move along the left end of the rotating shaft 1. When the moving hinge 3 moves to contact and fit with the left side surface of the friction washer 2, the above operation is repeated, and another friction washer 2, the reinforcing piece 4, and the spring washer 5 are sequentially placed at the left end of the rotating shaft 1 and pulled to move along the rotating shaft 1. When it moves to a suitable position, the locking nut 6 is placed at the left end of the rotating shaft 1 so that the left end of the rotating shaft 1 passes through its interior, and then the locking nut 6 is rotated along the rotating shaft 1 to apply pressure to the spring washer 5 to achieve the constant torque required for the hinge. When the locking nut 6 is rotated to a suitable position, the locking nut 6 is released to facilitate the fixation of all the components placed on the rotating shaft 1. During the movement of the reinforcing piece 4, the convex block on the reinforcing piece 4 contacts and is stuck in the square groove on the moving hinge 3. Then, the one-way bearing 7 is placed at the right end of the rotating shaft 1 and pulled to move along the rotating shaft 1. When the one-way bearing 7 moves to a suitable position, the left side surface of the one-way bearing 7 contacts and fits with the right side surface of the ring on the rotating shaft 1, and then the static hinge 8 is stuck on the one-way bearing 7 to complete the assembly of the device. When the device needs to be installed, it can be installed through the reserved hole positions on the moving hinge 3 and the static hinge 8. The first anti-slip pad 9 and the second anti-slip pad 10 can prevent slipping on the contact surface when the moving hinge 3 and the static hinge 8 are installed, increasing the fixing effect.
[0025] The above embodiments are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes made according to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
