[0032] Refer to Figures 1-3 , an embodiment provided by the present utility model: A new type of quick - installation fixing part includes a first support frame 1. A first cross - beam 2 is arranged at the top of the first support frame 1. First locking tongues 4 are fixedly connected to both sides of the first cross - beam 2. The outer walls of the first locking tongues 4 are slidably connected inside the first connecting groove 3. A second support frame 5 is slidably connected to the inner wall of the first support frame 1. A second connecting groove 7 is opened inside the second support frame 5. A second cross - beam 6 is slidably connected to the inner wall of the first cross - beam 2. Connecting components are arranged on both sides of the second cross - beam 6 for connecting the second cross - beam 6 with the second support frame 5. U - shaped connecting plates 10 are arranged on the outer walls of the first support frame 1 and the second support frame 5. An L - shaped connecting plate 9 is slidably connected inside the U - shaped connecting plates 10. The connecting components include second locking tongues 8. One side of the second locking tongues 8 is fixedly connected to both sides of the second cross - beam 6. The outer walls of the second locking tongues 8 are slidably connected inside the second connecting groove 7;

[0033] Specifically, first, the inner side of the U-shaped connecting plate 10 is attached to the wall. Subsequently, the L-shaped connecting plate 9 is drawn out from inside the U-shaped connecting plate 10 and adjusted according to the wall thickness. Then, the U-shaped connecting plate 10 and the L-shaped connecting plate 9 are fixed to the wall using iron nails. Next, the door frame is installed on the L-shaped connecting plate 9 and the U-shaped connecting plate 10 and fixed by welding. The door frame is composed of the first support frame 1 and the first cross beam 2 and the second support frame 5 and the second cross beam 6. Specifically, the first cross beam 2 is combined and connected by inserting the first locking tongue 4 into the first connecting groove 3 on the first support frame 1, while the second support frame 5 and the second cross beam 6 are combined and connected by inserting the second locking tongue 8 on the second cross beam 6 into the second connecting groove 7 on the second support frame 5. At this time, the second support frame 5 and the second cross beam 6 slide out inside the first support frame 1 and the first cross beam 2 to adapt to the wall thickness, ensuring firm and stable installation. In this way, through the quick-installation structure fixing parts, the quick installation and fixation of the door frame are realized, ensuring its stability and adaptability.

[0034] Figure 4 and Figure 5 , a connecting column 11 is fixedly connected to the outer wall of the second support frame 5, a second clamping block 19 is fixedly connected to the outer wall of the connecting column 11, a connecting block 12 is fixedly connected to the outer wall of the first support frame 1, a limiting block 15 is fixedly connected inside the connecting block 12, a limiting plate 13 is slidably connected inside the connecting block 12, a limiting groove 14 is opened inside the limiting plate 13, and the limiting plate 13 is slidably connected to the outer wall of the limiting block 15 through the limiting groove 14. A telescopic rod 16 is arranged inside the connecting block 12, a spring 17 is sleeved on the outer wall of the telescopic rod 16, one ends of the telescopic rod 16 and the spring 17 are both fixedly connected to the top of the limiting plate 13, and the other ends of the telescopic rod 16 and the spring 17 are both fixedly connected inside the connecting block 12. A first clamping block 18 is fixedly connected to the bottom of the limiting plate 13, and the outer walls of the first clamping block 18 and the second clamping block 19 are fitted together;

[0035] Specifically, the connecting column 11 on one side of the second support frame 5 passes through the connecting block 12 on the first support frame 1, and the second clamping block 19 on the outer wall of the connecting column 11 is fitted with the first clamping block 18 inside the connecting block 12, so that the connecting column 11 can be drawn out of the connecting block 12 but cannot be retracted into the connecting block 12, thereby adjusting the thickness of the door frame. The first clamping block 18 is limited inside the connecting block 12 through the limiting plate 13 and supported by the tension of the spring 17, so that the first clamping block 18 can be reset when the second clamping block 19 is retracted into the connecting block 12, ensuring the stability and reliability of the connecting column 11. In this way, the thickness adjustment of the door frame becomes more flexible and convenient, while ensuring the firmness of the installation. Through the design of the quick-installation structure fixing parts, the quick installation and stable fixation of the door frame are realized, adapting to different wall thicknesses, and ensuring the safety and stability during use.

[0036] Working principle: When using this new type of quick-install fixing piece, first, the inner side of the U-shaped connecting plate 10 is attached to the wall. Then, the L-shaped connecting plate 9 is pulled out from the inside of the U-shaped connecting plate 10 and adjusted according to the wall thickness. Subsequently, the U-shaped connecting plate 10 and the L-shaped connecting plate 9 are fixed to the wall using iron nails. Then, the door frame is installed on the L-shaped connecting plate 9 and the U-shaped connecting plate 10. The L-shaped connecting plate 9 and the U-shaped connecting plate 10 are connected to the door frame by welding. The door frame is composed of a support frame one 1 and a cross beam one 2 and a support frame two 5 and a cross beam two 6. The cross beam one 2 is combined and connected by inserting a locking tongue one 4 into the connecting groove one 3 on the support frame one 1. The support frame two 5 and the cross beam two 6 are combined and connected by inserting a locking tongue two 8 on the cross beam two 6 into the connecting groove two 7 on the support frame two 5. Subsequently, the support frame two 5 and the cross beam two 6 slide out inside the support frame one 1 and the cross beam one 2 to adapt to the wall thickness. And a connecting column 11 on one side of the support frame two 5 is inserted into a connecting block 12 on the support frame one 1. A second catch 19 on the outer wall of the connecting column 11 is fitted with a first catch 18 in the connecting block 12, so that the connecting column 11 can be pulled out and the connecting block 12 cannot be retracted into the connecting block 12, thereby adjusting the thickness of the door frame. The first catch 18 is limited in the connecting block 12 by a limiting plate 13 and supported by the tension of a spring 17, so that the first catch 18 can be reset when it is retracted into the connecting block 12 through the second catch 19.
