[0026] like Figure 1-7 As shown, a limiting groove 210 is provided at the rear end of the secondary frame 201 , and a sliding rod 212 is fixedly connected to the middle position of the inner end of the limiting groove 210 .

[0027] like Figure 1-7 As shown, a limiting nut 204 is provided at the front end of the cover plate 203 , the cover plate 203 is sleeved on the slide rod 212 , and the limiting nut 204 is threadedly connected to the rear portion of the slide rod 212 .

[0028] like Figure 1-7 As shown, a ring 213 is sleeved on the slide rod 212 , and the upper and lower ends of the ring 213 are fixedly connected to connecting rods 211 . The outer ends of the two groups of connecting rods 211 are located in the limiting grooves 210 and are fixedly connected to the limiting blocks 209 .

[0029] like Figure 1-7 As shown, the right ends of the two sets of limit blocks 209 pass through the limit slots 210 and are fixedly connected to the left ends of the two sets of leaf mounting plates 202. The outer ends of the two sets of limit blocks 209 are located in the limit slots 210 and are fixedly connected to the second fixing plates 207. The upper and lower ends of the cover plate 203 are fixedly connected to the first fixing plates 206.

[0030] During implementation, the hinge mounting plate 202 is used to fix the anti-theft door and the hinge and the secondary frame 201. The limit nut 204 is rotated to separate it from the slide rod 212, and the fastening bolt 205 is rotated to separate it from the threaded hole 208, so as to remove the cover plate 203. At this time, the first fixing plate 206 and the second fixing plate 207 are released from the limit and can pull the limit block 209 backward, thereby driving the hinge mounting plate 202 to move backward, making it convenient for personnel to remove the anti-theft door for maintenance or replacement.

[0034] During implementation, through the setting of the door frame assembly 1, the setting of the connecting piece 103 makes it convenient for personnel to fix and install the main frame 102 and the secondary frame 201 respectively. After the anti-theft door is removed, the position of the secondary frame 201 can be adjusted according to the new width of the anti-theft door through the setting of the sliding groove 104 and the sliding block 105. The overall structure is simple and stable, easy to use, and has better adaptability to different anti-theft doors.

[0035] The advantages of this technical solution in practical applications include but are not limited to the following:

[0036] 1. The hinge installation plate 202 is used to facilitate the fixed installation of the anti-theft door. The limit nut 204 and the fastening bolt 205 are rotated respectively to remove the cover plate 203. The limit can be released to pull the hinge installation plate 202 backwards, which is convenient for personnel to remove the anti-theft door for maintenance or replacement. Compared with the removal and replacement of the door frame and the anti-theft door as a whole, it is more convenient and has better economy and practicality.

[0037] 2. The setting of the connecting piece 103 makes it convenient for personnel to fix and install the main frame 102 and the secondary frame 201 respectively. The setting of the sliding groove 104 and the sliding block 105 can adjust the position of the secondary frame 201 according to the new width of the anti-theft door. The overall structure is simple and stable, easy to use, and has better adaptability to different anti-theft doors.

[0038] The present technical solution first uses the hinge mounting plate 202 to fix the anti-theft door and the hinge and the secondary frame 201, and then rotates the limit nut 204 to separate it from the slide rod 212, and rotates the fastening bolt 205 to separate it from the threaded hole 208, thereby removing the cover plate 203. At this time, the first fixing plate 206 and the second fixing plate 207 are released from the limit and can pull the limit block 209 backward, thereby driving the hinge mounting plate 202 to move backward, making it convenient for personnel to remove the anti-theft door for maintenance or replacement. After the anti-theft door is removed, the position of the secondary frame 201 can be adjusted according to the new width of the anti-theft door through the setting of the sliding groove 104 and the sliding block 105.
