[0023] Specifically, when the hinge needs to be disassembled, the two insertion rods 7 are driven to no longer be inserted into each other by rotating the threaded ring 6, and the insertion rod 7 can be pulled out from the threaded ring 6 alone. Then, the secondary hinge 11 is pulled to separate the secondary sleeve 10 from the installation sleeve 3, and then the secondary hinge 11 is removed. Next, the installation sleeve 3 is pulled outward, so that the installation sleeve 3 slides inside the fixing sleeve 4 under the elastic force of the first spring 5. Finally, the main sleeve 2 and the main hinge 1 can be further removed. Thereby, the convenience of the hinge is improved and the service life is extended.

[0024] Reference Figure 1 and Figure 3The connecting assembly includes a screw 13, the outer wall of which is threadedly connected to the inside of the secondary hinge 11; the outer walls of the main hinge 1 and the secondary hinge 11 are fixedly connected with a positioning rod 14; the insides of the main hinge 1 and the secondary hinge 11 are threadedly connected with a bolt 15, and the top of the outer wall of the bolt 15 is fixedly connected with a knob 16; the outer wall of the bolt 15 is rotatably connected with a fixing seat 17, the outer wall of the fixing seat 17 is fixedly connected to the outer wall of the main hinge 1, and the outer wall of the fixing seat 17 is fixedly connected to the outer wall of the secondary hinge 11; the outer wall of the bolt 15 is fixedly connected with a push plate 18, and the outer wall of the push plate 18 is slidably connected to the inside of the fixing seat 17; the outer wall of the bolt 15 is sleeved with a second spring 19; one end of the second spring 19 is fixedly connected to the inside of the fixing seat 17, and the other end of the second spring 19 is fixedly connected to the outer wall of the push plate 18;

[0025] Specifically, the screw 13 and the positioning rod 14 play the role of auxiliary installation, ensuring that the hinge can be accurately installed between the two objects that need to be connected. During the installation process, the screw 13 and the positioning rod 14 are first used to perform preliminary installation and positioning of the hinge. Then turn the knob 16 to drive the bolt 15 to rotate into the inside of the window. During this process, the bolt 15 will gradually enter the reserved hole inside the window and fit tightly with the window. When the bolt 15 completely enters the window, the second spring 19 will use its own elasticity to push back the push plate 18, thereby strengthening the connection between the bolt 15 and the window. This not only improves the stability of the hinge, but also effectively ensures the normal use of the hinge. At the same time, the hinge can maintain a stable connection state in various environments, avoiding safety hazards caused by loosening or falling off.

[0026] Working principle: When the hinge needs to be disassembled, the two plug rods 7 are driven to stop being inserted into each other by rotating the threaded ring 6, and the plug rod 7 can be pulled out from the threaded ring 6 alone, and then the auxiliary hinge 11 is pulled to separate the auxiliary sleeve ring 10 from the installation sleeve 3, and then the auxiliary hinge 11 is disassembled, and then the installation sleeve 3 is pulled outward, so that the installation sleeve 3 slides inside the fixed sleeve 4 under the elastic force of the first spring 5, and then the main sleeve ring 2 and the main hinge 1 are disassembled, so as to achieve the effect of quickly disassembling the hinge and improve the hinge The invention is convenient and prolongs the service life of the hinge. When the hinge needs to be firmly fixed, the hinge is preliminarily installed and positioned by means of the screw 13 and the positioning rod 14, and then the knob 16 is turned to drive the bolt 15 to rotate into the window. At the same time, the bolt 15 will drive the push plate 18 to compress the second spring 19, so that the second spring 19 can push the push plate 18 back, thereby strengthening the connection between the bolt 15 and the window, thereby achieving the effect of firmly fixing the hinge, improving the stability of the hinge, and ensuring the normal use of the hinge.
