[0024] refer to Figure 3 The reset and fixed assembly 9 includes a movable fixed block 91. The number of movable fixed blocks 91 is several, and the movable fixed blocks 91 are distributed at equal distances. A movable plate 92 is fixed on the outer side of the movable fixed block 91. A connecting plate 93 is fixedly connected to the bottom of the movable fixed block 91. A reset spring 94 is fixedly connected to the outer side of the connecting plate 93. The number of reset springs 94 is several, and the reset springs 94 are distributed at equal distances. The outer side of the reset spring 94 is fixedly connected to the inner side of the fixed frame 2.

[0025] As a technical optimization solution of the present invention, by providing the reset fixing component 9, the door frame can be quickly connected and fixed, effectively avoiding the situation where the door frame cannot be quickly connected and fixed, and effectively improving the connection and fixing efficiency of the door frame.

[0026] refer to Figure 3 A fixing groove 10 is opened on the inner side of the fixing frame 2. There are several fixing grooves 10, and the fixing grooves 10 are distributed at a distance. The fixing grooves 10 are used to fix the fixing frame 2.

[0027] As a technical optimization solution of the present invention, by providing a fixing groove 10, the fixing frame 2 can be pre-installed and fixed, thereby preventing an increase in the connection and fixing time of the door frame.

[0028] refer to Figure 5A fixing groove 2 11 is provided on the top of the fixing frame 2 6 . The number of the fixing grooves 2 11 is several, and the several fixing grooves 2 11 are distributed at equal distances. The fixing grooves 2 11 are used to fix the fixing frame 2 6 .

[0036] When the door frame is connected and fixed, the frame body 1 pre-fixed with the fixing frame 2 and the clamping frame 3 is moved inward along the bottom of the frame body 2 5. When the clamping frame 2 7 is inserted into the inside of the clamping frame 3, the fixing frame 2 6 moves to the top of the fixing frame 2, pressing the frame body 2 5, the fixing frame 2 6 and the clamping frame 2 7 downward. After the clamping frame 2 7 is clamped with the clamping frame 3, the extrusion fixing block 8 at the bottom of the fixing frame 2 6 moves downward to squeeze the movable fixing block 91. When the movable fixing block 91 is subjected to the extrusion force and moves outward, it drives the connecting plate 93 and the movable plate 92 to move outward. The connecting plate 93 drives the return spring 94 to squeeze outward. When the extrusion fixing block 8 moves downward to the appropriate position, the return spring 94 rebounds and drives the movable fixing block 91 to move inward to contact the extrusion fixing block 8 and limit and fix it. The door frame can be connected and fixed, thereby having the advantage of being easy to connect and fix quickly.
