[0021] The utility model will be described in detail in combination with the drawings and specific embodiments.

[0022] As shown in the accompanying drawings Figures 1-7The illustrated easy-to-assemble and disassemble screen window hinge 6 includes an upper hinge and a lower hinge. The upper hinge includes a fixed seat 1 and an upper rotating seat 2. The lower hinge includes a fixed seat 1 and a lower rotating seat 3. A cylindrical raised platform 11 is arranged on one end of the fixed seat 1. A rotating shaft 12 is coaxially arranged on the raised platform 11. The end face edge of the rotating shaft 12 away from the fixed seat 1 is chamfered. The chamfered structure facilitates the insertion of the rotating shaft 12 into the shaft hole 4. The upper rotating seat 2 and the lower rotating seat 3 are both provided with shaft holes 4 matching the rotating shaft 12. The upper rotating seat 2 and the lower rotating seat 3 are rotatably mounted to the corresponding fixed seat 1 through the cooperation of the shaft holes 4 and the rotating shaft 12. The upper rotating seat 2 or the lower rotating seat 3 is separated from the fixed seat 1 by the raised platform 11, so that a gap is formed between the fixed seat 1 and the upper rotating seat 2 or the lower rotating seat 3. This avoids deformation of the hinge after the installation of the screen window 6 due to stress, which in turn causes mutual friction and collision, thereby improving the fault tolerance of the hinge. One side of the shaft hole 4 of the lower rotating seat 3 is provided with a disassembly gap 7 connected to the end of the rotating seat. The disassembly gap 7 can pass through the rotating shaft 12. The angle of the part connecting the shaft hole 4 and the disassembly gap 7 is less than 180 degrees. The caliber of the end of the disassembly gap 7 connected to the shaft hole 4 is smaller than the rotating shaft. The shaft hole 4 can normally limit the rotating shaft 12 and prevent the rotating shaft 12 from being randomly removed from the disassembly gap 7. Meanwhile, the shaft hole 4 of the lower rotating seat 3 is provided with a deformation buffer groove 8 on the side away from the disassembly gap 7. The shaft hole 4 of the lower rotating seat 3 has a certain elastic deformation capacity on both sides, so that the rotating shaft can be deformed to enter or leave the shaft hole 4 under stress.

[0023] As a preferred embodiment, the upper rotating seat 2 and the lower rotating seat 3 are provided with limiting protrusions 9 near the end of the shaft hole 4, which are used for positioning and installing the screen window 6. The fixed seat 1, the upper rotating seat 2, and the lower rotating seat 3 are all provided with a plurality of conical countersunk bolt holes 10. The fixed seat 1 is fixedly installed on the window frame 5 through the cooperation of the countersunk bolt holes 10 and the conical countersunk bolts. The upper rotating seat 2 and the lower rotating seat 3 are respectively fixedly installed on the upper part and the lower part of the screen window 6 through the cooperation of the countersunk bolt holes 10 and the conical countersunk bolts.

[0024] As Figure 8As shown, the two fixed seats 1 are fixedly installed to the upper and lower portions of the window frame 5, and the upper and lower rotating seats 2 and 3 are fixedly installed to the upper and lower portions of the screen window 6. During installation, the screen window 6 is lifted and the shaft hole 4 of the upper rotating seat 2 is aligned with the rotating shaft of the upper fixed seat 1, then the screen window 6 is lifted to install the upper rotating seat 2 to the upper fixed seat 1, the dismounting gap 7 of the lower rotating seat 3 is aligned with the rotating shaft of the lower fixed seat 1, and finally the screen window 6 is pushed and the lower rotating seat 3 is pushed into the lower fixed seat 1, thus the installation of the screen window 6 is completed.

[0025] Similarly, during dismounting, the lower portion of the screen window 6 is pulled to disengage the lower rotating seat 3 from the lower fixed seat 1, and then the screen window 6 is pulled down to disengage the upper rotating seat 2 from the upper fixed seat 1, thus the dismounting of the screen window 6 is completed.

[0026] The above embodiment only represents one implementation of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be noted that for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the scope of the present application. Therefore, the scope of the present application should be subject to the appended claims.
