Through the snap-fit ​​connection between the limiting groove 141 and the limiting column 11, the overall position of the anti-theft column 14 can be fixed and installed, and the sound inlet hole 143 set on the anti-theft column 14 is convenient for noise reduction through the sound-absorbing cotton 142.

[0038] The working principle of this embodiment: Figure 1-3 and Figure 8First, the staff can install the anti-theft window frame on the folding house for fixing. The anti-theft column 14 installed on the window frame body 5 is conducive to anti-theft work. At the same time, the sound-absorbing cotton 142 inside the anti-theft column 14 can weaken the external sound. The sound enters the sound-absorbing cotton 142 through the sound inlet hole 143 to reduce the noise. At the same time, the whole sound inlet hole 143 is set in an inclined shape, which can reduce the phenomenon of rainwater infiltrating into the sound-absorbing cotton 142;

[0039] according to Figure 1-5 When it is necessary to disassemble and replace the anti-theft column 14, the fixing rod 133 can be manually pushed indoors to make the fixing rod 133 drive the positioning sleeve 131 to slide on the push rod 13, so that the positioning sleeve 131 pushes the reset spring 132 to shrink and operate, and at the same time, the positioning sleeve 131 and the positioning hole 3 are separated from each other, and the positioning work of the push rod 13 and the positioning sleeve 131 is released. Then, the push rod 13 is manually moved to make the push rod 13 slide on the fixed support frame 1 through the connecting groove 2, so that the push rod 13 drives the positioning sleeve 131 and the push rod 13 to slide on the window frame body 5 through the notch 12, and at the same time, the push rod 13 drives the support shaft 10 to pass through the mounting groove 8 on the window frame The main body 5 slides and contracts, so that the support shaft 10 pushes the positioning spring 9 to shrink and operate, so that the support shaft 10 drives the limiting column 11 to slide and separate from the limiting groove 141, and the positioning work of the anti-theft column 14 is released. Then, the fixing rod 133 is manually and slowly loosened, so that the positioning sleeve 131 is pushed by the elastic force of the reset spring 132 to slide and reset, so that the positioning sleeve 131 slides into another positioning hole 3 for engagement and connection, which is convenient for fixing the positions of the support shaft 10 and the limiting column 11 and avoiding the reset work. Then, the staff can disassemble the anti-theft column 14 to separate the anti-theft column 14 from the window frame main body 5, which is convenient for replacement operation, thereby improving the convenience of overall operation.

[0040] according to Figure 1 and Figure 6-7When the staff needs to disassemble the window frame body 5, the bolt 47 can be manually rotated to make the bolt 47 rotate and shift on the positioning column 4, and the bolt 47 slides on the fixed support frame 1, so that the bolt 47 and the receiving groove 41 are separated from each other. At the same time, the bolt 47 can pull the steel wire 44 through the circular plate 46, and the bolt 47 and the circular plate 46 are rotatably connected to avoid directly driving the steel wire 44 to rotate and entangle. The steel wire 44 can perform a stable corner rotation through the positioning shaft 45, which is convenient for the steel wire 44 to pull the positioning block 43, so that the positioning block 43 is slidably separated from the positioning groove 7, so that the positioning block 43 is completely retracted into the interior of the receiving groove 41, and the positioning block 43 can push the connecting spring 42 to retract and operate, which is convenient for the subsequent resetting work, and then the window frame body 5 is pulled to separate the positioning column 4 from the connecting hole 6 on the window frame body 5, thereby completing the overall disassembly work, improving the convenience during the overall operation, and completing a series of work.
