[0024] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] This application discloses a connection structure for square tube doors.

[0027] Reference Figures 1-2 A connection structure for square tube doors includes a frame 1, a horizontal frame 2 on the frame 1, and a connecting component 3 between the horizontal frame 2 and the frame 1. The horizontal frame 2 is installed on the frame 1 through the connecting component 3.

[0028] There are two parallel borders 1, and the borders 1 are vertically aligned. Horizontal frames 2 are located between the two borders 1, and are spaced out at intervals along the vertical direction of the borders 1. Preferably, there are three horizontal frames 2 evenly spaced.

[0029] Reference Figures 2-3 The connecting component 3 includes a connecting block 31, which is mounted on the frame 1. One end of the horizontal frame 2 has a connecting groove 21. In use, the connecting block 31 on the frame 1 is engaged in the connecting groove 21 of the horizontal frame 2. To improve the stability of the connection between the frame 1 and the horizontal frame 2, a connecting bolt 32 is provided on the connecting block 31. One end of the connecting bolt 32 passes through the connecting block 31 and is inserted into the frame 1. A connecting nut 321 is provided on the end of the connecting bolt 32 inserted into the frame 1. The connecting nut 321 is threadedly connected to the connecting bolt 32, and one end of the connecting nut 321 is pressed against the frame 1, thereby enabling the connecting block 31 to be mounted on the frame 1.

[0030] Reference Figures 3-4To improve the stability of the connecting block 31 on the frame 1, a first anti-slip groove 311 and a second anti-slip groove 312 are formed on the connecting block 31. The connecting block 31 is pressed against the frame 1 through the first anti-slip groove 311, which increases the friction between the connecting block 31 and the frame 1, reducing the rotation of the connecting block 31 on the frame 1 during use. The second anti-slip groove 312 is formed on one side where the connecting bolt 32 passes through the connecting block 31. When the connecting bolt 32 and the connecting nut 321 lock the connecting block 31 onto the frame 1, the nut of the connecting bolt 32 abuts against the second anti-slip groove 312 of the connecting block 31, reducing the relative rotation between the connecting bolt 32 and the connecting block 31 during use, and improving the stability of the connecting block 31 on the frame 1.

[0031] Since the position of the horizontal frame 2 on the frame 1 is mainly determined by the connecting blocks 31, guide rods 11 are provided on the frame 1 to improve the accuracy of the position of several connecting blocks 31 on the frame 1. Two guide rods 11 are provided on the frame 1 at intervals, and the cross-section of the two guide rods 11 forms a T-shape. One end of the cross-section of the guide rod 11 is integrally formed with the frame 1, and the other end extends towards the side close to the connecting block 31. The connecting block 31 is provided with a mounting groove 33, and two mounting grooves 33 are provided corresponding to the guide rods 11. In use, the guide rods 11 on the frame 1 are engaged in the mounting grooves 33 of the connecting block 31, and the connecting block 31 slides along the length direction of the guide rod 11 in the vertical direction of the frame 1, so that the connecting block 31 can only move in the vertical direction. The horizontal position is limited by the guide rods 11. After the connecting block 31 moves to the designated position, the connecting block 31 is locked to the frame 1 by the connecting bolts 32 and the connecting nuts 321.

[0032] Reference Figure 4 To improve the ease of installing the connecting block 31 on the frame 1, a guide slope 331 is formed on the connecting block 31. The guide slope 331 is inclined towards the side close to the mounting groove 33. Therefore, when installing the connecting block 31, the guide slope 331 on the connecting block 31 guides the guide rod 11, thereby improving the ease of cooperation between the connecting block 31 and the guide rod 11.

[0033] In use, simply install the connecting block 31 on the frame 1, and then insert the connecting block 31 on the frame 1 into the connecting groove 21 of the horizontal frame 2. This eliminates the need to adjust the spacing between the two frame 1s, greatly improving the installation efficiency of the frame 1 and the horizontal frame 2.

[0034] To improve the ease of connection between the connecting block 31 and the horizontal frame 2, an inclined surface 22 is formed at one end of the horizontal frame 2 near the connecting block 31, and the inclined surface 22 is inclined inward toward the connecting groove 21. When the connecting block 31 is inserted into the connecting groove 21 of the horizontal frame 2, the inclined surface 22 on the horizontal frame 2 guides the connecting block 31, thereby improving the ease of insertion of the connecting block 31 into the horizontal frame 2.

[0035] Furthermore, the horizontal frame 2 has a mounting hole 23 that communicates with the connecting groove 21, and the connecting block 31 has a through hole 313 that corresponds to the mounting hole 23. A positioning bolt 24 is provided on the horizontal frame 2. When the connecting block 31 is inserted into the connecting groove 21 of the horizontal frame 2, the mounting hole 23 on the horizontal frame 2 communicates with the through hole 313 on the connecting block 31. One end of the positioning bolt 24 passes through the mounting hole 23 on the horizontal frame 2 into the through hole 313 of the connecting block 31, and the positioning bolt 24 is threadedly connected to the horizontal frame 2. Because the positioning bolt 24 passes through the through hole 313 of the connecting block 31, it prevents the connecting block 31 from sliding laterally.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
