Two second frame groups 150 are provided, and the two second frame groups 150 respectively form the left edge and the right edge of the door frame. The connecting component connects and fixes the first frame group 100 and the second frame group 150.

[0031] The first frame group 100 includes a first profile 110 and a first square tube 120. Figure 1 The first profile 110 has a first groove 130, the first groove 130 accommodates the first square tube 120 and the first groove 130 matches the outer profile of the first square tube 120, and a socket 140 is provided between the first profile 110 and the first square tube 120, referring to Figure 3 , the socket 140 extends up and down.

[0032] The first frame group 100 includes a second profile 160 and a second square tube 170. Figure 1 The second profile 160 has a second groove 300, the second groove 300 accommodates the second square tube 170 and the second groove 300 matches the outer profile of the second square tube 170, refer to Figure 4 A first sealing plate 180 is provided at both ends of the second square tube 170 .

[0033] Therefore, the first square tube 120 is placed in the first groove 130, the first square tube 120 is confined in the first groove 130, and the first square tube 120 and the first profile 110 can be combined to form the first frame group 100 by welding, and the second square tube 170 is placed in the second groove 300, the second square tube 170 is confined in the second groove 300, and the second square tube 170 and the second profile 160 can be combined to form the second frame group 150 by welding, thereby improving the strength of the first frame group 100 and the second frame group 150, reducing the deformation problem during welding of the first frame group 100 and the second frame group 150, and ensuring that the flatness of the door frame meets the requirements. Moreover, the first frame group 100 and the second frame group 150 have a simple structure, are easy to manufacture, and have low production costs.

[0034] Among them, the connecting assembly includes a connecting block 190, a first bolt 200 and a second bolt 210. The connecting block 190 is connected to the first sealing plate 180 through the first bolt 200. The shape of the connecting block 190 matches the socket 140. The connecting block 190 can be inserted into the socket 140. The connecting block 190 is connected to the first square tube 120 through the second bolt 210.

[0035] Therefore, the connecting block 190 is connected to the first sealing plate 180 by using the first bolt 200, so that the connecting block 190 is fixed to the second frame group 150, and then the connecting block 190 is inserted into the socket 140, and the connecting block 190 is connected to the first square tube 120 by using the second bolt 210, so that the first frame group 100 and the second frame group 150 are connected and fixed. Therefore, there is no need to use a clamp to position the first frame group 100 and the second frame group 150 when welding, and the connecting block 190 can be buried in the socket 140 to improve the positioning accuracy, thereby improving the welding accuracy.

[0036] In some embodiments of the present invention, referring to Figure 5 and Figure 6 The connecting block 190 has a first positioning pin 220 and a second positioning pin 230, a first pin hole 240 is provided between the first profile 110 and the first square tube 120, and the first sealing plate 180 has a second pin hole 250. The first pin hole 240 accommodates the first positioning pin 220, and the second pin hole 250 accommodates the second positioning pin 230.
