[0021] The most critical concept of the present invention is to provide a leveling fixing portion comprising two screws and a nut, and to achieve fine-tuning of the height in the vertical direction by adjusting the depth of the screws screwed into the nut, thereby achieving adjustment of the entire connection structure.

[0022] In order to further discuss the feasibility of the concept of the present invention, the technical content, structural features, achieved objectives and effects of the present invention are described in detail below in conjunction with the implementation methods and the accompanying drawings.

[0023] Example 1

[0024] See also Figure 1 、 Figure 2 as well as Figure 3 , a levelable beam connection structure, including a first support rod 1 and a second support rod 2; the first support rod 1 is provided with a connecting piece 3 and a leveling fixing part 4; the first support rod 1 is connected to the second support rod 2 through the connecting piece 3; the leveling fixing part 4 includes two screws 41 in the same vertical direction, and a nut 42 is provided between the two screws 41; the two screws 41 are fixed on the nut 42; a rectangular cavity 22 is provided at the end of the second support rod 2, and the screw 41 is placed in the rectangular cavity 22.

[0025] The leveling fixing portion 4 and the connecting piece 3 are arranged on the first support rod 1, and the centers of the two are basically on the same horizontal plane. The relative position of the highest points of the two can be adjusted by the screw 41 of the leveling fixing portion 4. After the first support rod 1 and the second support rod 2 are connected by the connecting piece 3, no relative displacement occurs; and the leveling fixing portion 4 is set at another connection point between the first support rod 1 and the second support rod 2. By adjusting the depth of the screw 41 screwed into the nut 42, the height can be fine-tuned in the vertical direction. The leveling fixing portion 4 is placed in the rectangular cavity 22, and the screw 41 in the upper half of the leveling fixing portion 4 supports the second support rod 2, which is equivalent to adjusting the height of the second support rod 2, thereby achieving adjustment of the entire connection structure.

[0026] Example 2

[0027] Based on Example 1, the connecting piece 3 is connected to the second support rod 2 through a bolt structure 5; the rectangular cavity 22 is provided with a first opening 21 and a second opening 23 for facilitating the leveling fixing part 4 to enter the rectangular cavity 22; the first opening 21 and the bolt structure 5 are both located on the same side of the second support rod 2, and the second opening 23 is located on the end face of the second support rod 2.

[0028] The first opening 21 and the second opening 23 are connected. When the first support rod 1 is connected to the second support rod 2, the positions of the two screw rods 41 are pre-adjusted first, and then the end face of the second support rod 2 is close to the first support rod 1. The leveling fixing portion 4 enters the rectangular cavity 22 from the first opening 21, and then the second support rod 2 approaches the connecting piece 3, and relatively, the leveling fixing portion 4 enters any position in the rectangular cavity 22 along the second opening 23. By adjusting the tightness of the bolt structure 5, the relative position between the second support rod 2 and the first support rod 1 in the direction perpendicular to the connecting piece 3 can be adjusted. The width of the second opening 23 in the vertical direction is smaller than the height of the leveling fixing portion 4, and the leveling fixing portion 4 will not fall off from the second opening 23 after entering the rectangular cavity 22.

[0029] Example 3

[0030] Based on Example 2, an oblong hole 7 is provided on the connecting plate 3; a circular hole is provided on the side wall of the second support rod 2, and the circular hole is connected to the oblong hole 7 through the bolt structure 5; the length direction of the oblong hole 7 is the same as the length direction of the second support rod 2.

[0031] By providing the oblong hole 7 , the relative position between the first support rod 1 and the second support rod 2 in the length direction of the oblong hole 7 can be adjusted.

[0032] In summary, the levelable beam connection structure designed in the present invention can adjust the relative positions of the first support rod 1 and the second support rod 2 in three-dimensional space through the leveling fixing portion 4, the bolt structure 5 and the oblong hole 7.

[0033] Example 4

[0034] Based on Example 3, two second support rods 2 are provided, and two groups of bolt structures 5 are provided; the middle part of the connecting plate 3 is fixed on the first support rod 1, and both ends of the connecting plate 3 are connected to the second support rod 2 through the bolt structure 5.

[0035] In this case, two different second support rods 2 can be fixed on the first support rod 1 at the same height.

[0036] Example 5

[0037] Based on Example 4, the connecting piece 3 is provided with a reinforcing rib 31, and the length direction of the reinforcing rib 31 is the same as the length direction of the second support rod 2. The reinforcing rib 31 is provided to increase the strength of the connecting piece 3 and achieve a more stable connection effect.

[0038] Example 6

[0039] Based on Example 5, at least two oblong holes 7 are provided at either end of the connecting plate 3, and one reinforcing rib 31 is provided. The oblong holes 7 are evenly distributed on both sides of the reinforcing rib 31, thereby enhancing the connection strength and stability between the connecting plate 3 and the second support rod 2.

[0040] Example 7

[0041] On the basis of Example 6, a reinforcing plate 6 is provided at the connection between the bolt structure 5 and the circular hole in the second support rod 2 to enhance the connection strength and stability between the second support rod 2 and the bolt structure 5 .

[0042] Example 8

[0044] Example 9

[0045] Based on Example 8, the connecting piece 3 and the nut 42 are fixed to the first support rod 1 by welding. The specific location of the connection between the second support rod 2 and the first support rod 1 can be determined according to the actual construction site. Once determined, the connecting piece 3 and the nut 42 are first welded to the first support rod 1, and then the screw 41 is installed on the nut 42 to form the leveling fixing portion 4. Finally, the second support rod 2 can be connected to the first support rod 1.

[0046] Example 10

[0047] On the basis of the above embodiment, the first support rod 1 is a vertical support rod, and the second support rod 2 is a horizontal support rod; the first support rod 1 and the second support rod 2 are both made of steel.

[0048] In summary, the present invention provides a leveling beam connection structure, which can achieve fine-tuning of the height in the vertical direction by adjusting the depth of the screw screwed into the nut, and the leveling fixing part is placed in the rectangular cavity, and the screw in the upper half of the leveling fixing part supports the second support rod, which is equivalent to adjusting the fixed height of the second support rod. By adjusting the tightness of the bolt structure, the relative position between the second support rod and the first support rod perpendicular to the direction of the connecting plate can be adjusted. By providing an oblong hole, the relative position between the first support rod and the second support rod in the length direction of the oblong hole can be adjusted. That is, by the leveling fixing part, the bolt structure and the oblong hole, the relative position of the first support rod and the second support rod in three-dimensional space can be adjusted, thereby achieving the adjustment of the entire connection structure. The first support rod and the second support rod, which are made of steel and in the shape of a rectangular column, are convenient for stable connection, and the reinforcing ribs, reinforcing plates, multiple oblong holes and round holes further ensure the stability of the connection.
