[0021] 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.

[0022] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a whole assembled paint hinge, including a connecting piece 1, a rotating cylinder 2 is fixedly connected to the outer wall of the connecting piece 1, a reinforcing cylinder 3 is fixedly connected to the outer wall of the connecting piece 1, a central axis 4 is rotatably connected to the inner wall of the rotating cylinder 2, a threaded rod 5 is threadedly connected to the inner part of the central axis 4, an internal thread 7 is provided inside the central axis 4, a connecting cylinder 6 is provided inside the central axis 4, a fixed axis 8 is provided inside the threaded rod 5, the outer wall of the fixed axis 8 is slidably connected to the inner wall of the internal thread 7, a spring 9 is provided on the outer wall of the central axis 4, a connecting piece 2 10 is rotatably connected to the outer wall of the central axis 4, one end of the spring 9 is fixedly connected to the inside of the connecting piece 2 10, a plurality of slots 11 are provided inside the connecting piece 2 10, and a fixing component is provided inside the connecting piece 2 10.

[0023] Specifically, the threaded connection between the fixed shaft 8 and the central shaft 4 makes the removal process of the hinge easier, thereby reducing the difficulty of maintenance and replacement, and no longer requires a lot of time and effort to disassemble and replace the hinge. This hinge is designed with a spring 9 on the outer wall of the central shaft 4. This innovative design gives the hinge a reset function. When the door is opened, the force of the spring 9 will automatically close the door, greatly improving the user experience. It is not only convenient for users, but also can protect the door and hinge to a certain extent and extend their service life. The connection between the connecting piece 1 and the reinforcing tube 3 increases the use area of ​​the hinge and enhances the stability of the connection, making the hinge more stable when subjected to pressure and weight. The practicality and durability of the hinge are significantly improved.

[0024] Reference Figure 1 and Figure 2 The fixing component includes a threaded nail 12, the outer wall of the threaded nail 12 is threadedly connected to the inside of the connecting piece 10, a fixing block 13 is arranged on the outer wall of the threaded nail 12, a groove 14 is opened inside the fixing block 13, the outer wall of the fixing block 13 is rotatably connected to a connecting rod 16, the fixing block 13 is rotatably connected to a rotating shaft 15, one side of the outer wall of the rotating shaft 15 is rotatably connected to the inside of the groove 14, the outer wall of the rotating shaft 15 is rotatably connected to the inside of the connecting rod 16, the outer wall of the connecting rod 16 is rotatably connected to a moving block 17, the outer wall of the moving block 17 is threadedly connected to the outer wall of the threaded nail 12, a plurality of slots 11 are linearly distributed inside the connecting piece 10, and the other end of the spring 9 is fixedly connected to the inside of the connecting piece 1.

[0025] Specifically, when the threaded nail 12 is rotated, the movable block 17 will approach the fixed block 13. In this process, the rotating shaft 15 and the connecting rod 16 form a firm angle, so that the doors and windows can maintain a stable operating state during long-term use. One end of the rotating shaft 15 is against the inside of the hole, which not only enhances the firmness of the connection, but also effectively prevents the screws from loosening. Therefore, during the process of opening and closing the doors and windows, the noise caused by loose screws can be avoided, which greatly improves the comfort of use and adds protection to the service life of the doors and windows.

[0026] Working principle: When the whole assembled painted hinge is needed, firstly, holes are made on the connection target, the screw 12 is on the outward side of the connecting piece 1, the fixed block 13 and the movable block 17 are on the inward side of the connecting piece 1. When the screw 12 is driven in with a tool, the movable block 17 moves closer to the fixed block 13, so that the rotating shaft 15 rotates, and the movable block 17 rotates with the rotating shaft 15, so that the rotating shaft 15 is against the hole, and the connection between the connecting piece 1 and the connecting piece 2 10 and the doors and windows is strengthened, so as to improve the quality of the hinge. The traditional hinge is connected to the doors and windows by ordinary screws 12. Some anti-theft doors and windows are heavy, which often causes the hinge to be overloaded, thereby making the hinge Loose connection further leads to loud noise when opening windows and doors and poor usability. Therefore, fixed blocks 13 and movable blocks 17 connected by threaded nails 12 are used to improve user experience and extend the service life of the hinge. The load-bearing shaft part is the fixed shaft 8 and the central shaft 4. The fixed shaft 8 is threadedly connected to the inside of the connecting tube 6 and is further reinforced by the internal thread 7 to achieve the effect of improving the quality of the hinge. The outer wall of the hinge is painted and has stronger corrosion resistance. A spring 9 is arranged on the outer wall of the central shaft 4, so that the door has the function of automatic closing, which improves the functionality of the hinge. The connecting piece 1 is also connected to the reinforcing tube 3 to protect the spring 9, thereby achieving the effect of improving the stability of the hinge.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
