[0002] A damper is a device that provides resistance to motion and dissipates motion energy, and is widely used in industries such as aerospace, aviation, military, guns, and automobiles.
[0003] When using a cabinet door cover, a damper is required for damping. Most products on the market use a rotary damper to achieve slow descent of the cover, with resistance in both directions, resulting in a relatively heavy opening of the cover. However, the damper cannot generate buffering during small-angle rotation, and as a result, the damper may be damaged after long-term use, causing the damper to malfunction. Summary of the Invention
[0004] Aiming at the deficiencies of the prior art, the utility model provides a rotary cabinet door cover damper that can adapt to slow closing of a cover plate in a large range, which has the advantages of being able to adapt to slow closing of a cover plate in a large range, etc., and solves the problem that the damper cannot generate buffering during small-angle rotation.
[0005] A rotary cabinet door cover damper of the utility model that can adapt to slow closing of a cover plate in a large range includes a rotary damper main body. At the top of the damper main body, there is an adjustable-angle fixing ear. At the top of the adjustable-angle fixing ear, there is a screw connected by thread. At the bottom of the adjustable-angle fixing ear, there is a rotary bearing. At the bottom of the inner cavity of the adjustable-angle fixing ear, there is an upper rotating shaft rotatably connected. At the bottom of the upper rotating shaft, there is a lower rotating shaft. Inside the damper main body, there is a damper. One end of the damper is connected through a gasket. One end of the damper is sleeved with a heavy compression spring, and one end of the heavy compression spring is in contact with the surface of the gasket. At the bottom of the damper main body, there is an adjusting nut connected. After the damper of the utility model is assembled and fixed, the closing of the cover drives the adjustable-angle fixing ear, the upper rotating shaft, and the lower rotating shaft to rotate. Since the lower rotating shaft is fixed to the slot in the rotary damper main body and cannot rotate, it can only move linearly, thereby compressing the heavy compression spring and the damper, so that the cover plate closes slowly. The connection between the adjustable-angle fixing ear and the upper rotating shaft adopts a polygonal connection method, making the installation angle adjustable. The rotary damper main body is connected to the adjusting nut. By adjusting the depth of the adjusting nut, the heavy compression spring and the damper are compressed, increasing the pressure of the heavy compression spring, thereby increasing the force of the rotary cabinet door cover damper.

At the bottom of the adjustable angle fixing ear 2, there is a rotary bearing 3. At the bottom of the inner cavity of the adjustable angle fixing ear 2, there is an upper rotating shaft 4 rotatably connected. At the bottom of the upper rotating shaft 4, there is a lower rotating shaft 5. Inside the damper main body 6, there is a damper 9. One end of the damper 9 is connected through a gasket 8. One end of the damper 9 is sleeved with a heavy compression spring 7 and one end of the heavy compression spring 7 is in contact with the surface of the gasket 8. At the bottom of the damper main body 6, there is an adjusting nut 10. After the damper 9 of the present utility model is assembled and fixed, the closing of the lid drives the adjustable angle fixing ear 2, the upper rotating shaft 4 and the lower rotating shaft 5 to rotate. Since the lower rotating shaft 5 is fixed to the slot in the rotary damper main body 6 and cannot rotate, it can only move linearly, thus compressing the heavy compression spring 7 and the damper 9, so that the cover closes slowly. The connection between the adjustable angle fixing ear 2 and the upper rotating shaft 4 adopts a polygonal connection method, making the installation angle adjustable. The rotary damper main body 6 is connected to the adjusting nut 10. By adjusting the depth of the adjusting nut 10, the heavy compression spring 7 and the damper 9 are compressed, increasing the pressure of the heavy compression spring 7, thereby increasing the force of the rotary cabinet door cover damper.
[0019] A notch is provided at the top of the damper main body 6, and the rotary bearing 3 is arranged at the notch at the top of the damper main body 6.

[0021] The adjustable angle fixing ear 2 and the upper rotating shaft 4 adopt a polygonal connection and are in close contact with each other.
[0022] The surface of the adjusting nut 10 is threadedly connected to the inner cavity of the damper main body 6, and the diameter of the adjusting nut 10 is smaller than the diameter of the inner cavity of the damper main body 6.
[0023] When using the present utility model: After the damper 9 is assembled and fixed, the closing of the lid drives the adjustable-angle fixing ears 2, the upper rotating shaft 4 and the lower rotating shaft 5 to rotate. Since the lower rotating shaft 5 is fixed to the slot in the rotating damper body 6 and cannot rotate, it can only move linearly, thereby compressing the heavy compression spring 7 and the damper 9, so that the cover plate closes slowly. The connection between the adjustable-angle fixing ears 2 and the upper rotating shaft 4 adopts a polygonal connection method, making the installation angle adjustable. The rotating damper body 6 is connected to the adjusting nut 10. By adjusting the depth of the adjusting nut 10, the heavy compression spring 7 and the damper 9 are compressed, increasing the pressure of the heavy compression spring 7, thereby increasing the damping force of the rotating cabinet door cover plate damper.
