[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] In this embodiment, as Figures 1-6 As shown, a smoothly rotating hinge includes a mounting plate 1, a hinge body 2, and a pivot 3. The pivot 3 is fixedly mounted on the top of the mounting plate 1, serving as support and rotation guide. The hinge body 2 is positioned above the pivot 3. The hinge body 2 and the pivot 3 are connected by a rotating assembly. The hinge body 2 is directly connected to movable parts such as doors and windows through a fixing hole 21, thereby realizing the function of rotating and opening the movable parts. The rotating assembly effectively reduces the occurrence of jamming, thus ensuring that the hinge body 2 can maintain a good working condition over a long period of time.

[0027] The rotating assembly includes a rotating column 4 and a bearing 5. One side of the hinge body 2 is fixedly connected to the side wall of the rotating column 4. The hinge body 2 and the rotating column 4 are fixedly connected by welding or other means. The rotating column 4 has a bearing groove 6 and a placement groove 7 inside. The bearing groove 6 and the placement groove 7 are connected. The bearing groove 6 is located below the placement groove 7. The bearing 5 is located inside the bearing groove 6. The shape and specifications of the bearing 5 and the bearing groove 6 are compatible to ensure that there will be no shaking or deviation during operation. One end of the rotating shaft 3 passes through the bearing 5 and is inserted into the placement groove 7, so that the rotating shaft 3 can rotate stably in the rotating column 4.

[0028] Among them, such as Figures 2-5 As shown, the shape and specifications of the bearing 5 are adapted to the shape and specifications of the bearing groove 6, which facilitates a tight and stable fit between the two, ensuring that the bearing 5 will not undergo relative displacement during long-term rotation, thereby effectively improving the overall structural stability of the hinge and reducing potential wobbling and other adverse conditions caused by assembly gaps. A groove 51 is provided on the inner side wall of the bearing 5, and several noise-absorbing steel balls 52 are evenly arranged inside the groove 51. The noise-absorbing steel balls 52 are existing technology, which can greatly reduce the noise generated by friction during the operation of the bearing 5 through their own rolling and buffering, thereby creating a quiet and comfortable operating environment and making the rotation smoother.

[0029] Among them, such as Figures 1-6 As shown, a number of mounting holes 11 are fixedly provided on one side of the mounting plate 1. The number and position of the mounting holes 11 can be adjusted according to the actual installation environment. When installing the hinge, the user connects the mounting plate 1 to the door, door frame, furniture and other installation components through the aforementioned mounting holes 11 to increase the overall stability.

[0030] Among them, such as Figures 1-6As shown, the hinge body 2 is designed in an L-shape to enhance the practicality and applicability of the hinge. It can effectively disperse the stress generated by the moving parts during the opening and closing process, making the overall force of the hinge more uniform and further improving the durability of the hinge. Several fixing holes 21 are provided on the surface of the hinge body 2. Users can connect the hinge body 2 to the movable parts such as doors and windows through the above-mentioned fixing holes 21 to increase the overall stability.

[0031] Among them, such as Figures 3-5 As shown, a limiting plate 8 is installed on the top of the rotating shaft 3. An elastic telescopic component 9 is provided between the limiting plate 8 and the top wall of the placement groove 7, so that the hinge has an adjustment function in the vertical direction. The height of the connecting part with the hinge body 2 can be adjusted, thereby realizing fine adjustment of the installation position. A lubrication ring 10 is fixedly installed on the outer wall of the limiting plate 8. The outer diameter of the lubrication ring 10 is adapted to the inner diameter of the placement groove 7. Through the cooperation of the bearing 5 and the lubrication ring 10, when the rotating column 4 and the rotating shaft 3 rotate relative to each other, the rotation of the rotating column 4 can be made smoother by the lubrication of the lubrication ring 10, reducing the friction between the rotating column 4 and the rotating shaft 3, thereby achieving the purpose of silent rotation and increasing the service life of the hinge.

[0032] Among them, such as Figure 1 As shown, the inner diameter of the bearing groove 6 is larger than the inner diameter of the placement groove 7, which limits the size and ensures the overall practicality of the hinge.

[0033] Among them, such as Figure 5 As shown, the lubrication ring 10 is made of a high wear-resistant composite material with elasticity and self-lubrication, which can achieve the self-lubricating effect of the lubrication ring 10 during rotation, and has high wear resistance, which can extend its service life.

[0034] Example 2

[0035] The difference from Example 1 is that, as in Example 1, Figures 3-5 As shown, the elastic telescopic component 9 is set as a spring, which allows the height position of the rotating column 4 to be adjusted.

[0036] When installing this smooth-rotating hinge, first fix the mounting plate 1 to the door, door frame, furniture and other mounting components by means of screw connection through several mounting holes 11 on the surface of the mounting plate 1. Press the rotating post 4 to adjust the position of the hinge body 2 in the vertical direction. Then fix the hinge body 2 to the door, window and other movable parts by means of screw connection through several fixing holes 21 on the surface of the hinge body 2. When the hinge body 2 rotates, the bearing 5 and the lubrication ring 10 cooperate with each other, thereby reducing the friction between the rotating post 4 and the rotating shaft 3, achieving the purpose of silent rotation and making the rotation smoother.

[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
