[0028] In an exemplary embodiment of the present disclosure, an aluminum square tube connection device is provided, such as Figure 1 As shown, Figure 1 is a schematic diagram showing the structure of an aluminum square tube connection device according to an exemplary embodiment; Figure 2 According to an exemplary embodiment Figure 1 The middle is an enlarged view of part A showing the position of the reinforcement plate; Figure 3 According to an exemplary embodiment Figure 1 The middle is an enlarged view of part B showing the opening position; Figure 4 According to an exemplary embodiment Figure 1 The middle is an enlarged view of part C showing the location of the stabilizer. Figures 1 to 4 Provide explanation.

[0029] Some specific implementation methods described below are intended to facilitate those skilled in the art to understand this embodiment, and this embodiment is not limited to some specific implementation methods described below.

[0030] Reference Figure 1 An exemplary embodiment of the present disclosure provides an aluminum square tube connection device, the aluminum square tube connection device comprising:

[0031] The carrier 1 partially extends into the interior of the aluminum square tube and is used to vertically clamp the aluminum square tube, and the other part extends outside the aluminum square tube;

[0032] Connecting rod 2, fixed to bearing member 1 and used for hanging on keel;

[0033] The locking member 3 is detachably connected to the connecting rod 2 and together with the connecting rod 2 forms a frame structure circumferentially surrounding the keel.

[0034] For example, refer to Figure 1 and Figure 2 The bearing member 1 also includes a bottom plate 113 for supporting the aluminum square tube and a top plate 111 for covering the top surface of the aluminum square tube. The top plate 111 and the bottom plate 113 are both flat plates and are arranged on opposite sides of the reinforcement structure 11. A reinforcement plate 112 is fixedly connected between the bottom plate 113 and the top plate 111. The reinforcement plate 112 is vertically arranged and the bottom end is fixedly connected to the bottom plate 113. The top end of the reinforcement plate 112 is fixedly connected to the top plate 111. A reinforcement structure 11 that fills the top opening of the aluminum square tube is formed between the reinforcement plate 112, the top plate 111, and the bottom plate 113. The reinforcement structure 11 covers and blocks part of the top opening of the top plate 111. The top plate 111 forms the top surface of the reinforcement structure 11, and the bottom plate 113 forms the bottom surface of the reinforcement structure 11. The top surface of the reinforcement structure 11 is exposed from the top opening of the aluminum square tube, and the bottom surface of the reinforcement structure 11 is located inside the aluminum square tube. There are at least two reinforcing plates 112. When there are two reinforcing plates 112, the two reinforcing plates 112 are respectively arranged at the edges of the top opening of the aluminum square tube. When the reinforcing structure 11 is plugged into the top opening of the aluminum square tube, the two reinforcing plates 112 respectively abut against the inner wall of the opening at the top of the aluminum square tube; when there are three reinforcing plates 112, two of the three reinforcing plates 112 are generally arranged at the edges of the top opening of the aluminum square tube as mentioned above, and respectively abut against the inner wall of the opening at the top of the aluminum square tube when the reinforcing structure 11 is plugged into the top opening of the aluminum square tube. The other reinforcing plate 112 is fixed at the position between the two reinforcing plates, so as to further enhance the connection strength between the top plate 111 and the bottom plate 113, and to improve the overall structural strength of the reinforcing structure 11.

[0035] Reference Figure 1 and Figure 3The connecting rod 2 is vertically arranged and its bottom end is fixedly connected to the top plate 111. The top end of the connecting rod 2 extends toward the keel and is bent to form a hook-shaped end that can be hung on the keel. The connecting rod 2 includes a straight rod 22 fixed to the bearing member 1 and a suspension rod 21 with a hook-shaped end. The straight rod 22 is a long straight rod-shaped structure arranged vertically. The bottom end of the straight rod 22 is fixedly connected to the top plate 111. The top end of the straight rod 22 is fixedly connected to the bottom end of the suspension rod 21. The top end of the suspension rod 21 extends toward the keel and passes from one side of the keel, extends around the top surface of the keel to the other side of the keel, and then bends to wrap around the bottom of the keel to form a hook-shaped structure. The end of the suspension rod 21 bent to form the hook-shaped structure is higher than the end of the suspension rod 21 fixedly connected to the straight rod 22.

[0036] Reference Figure 2 and Figure 3 The locking member 3 includes a limiting bolt 31 that passes through the connecting rod 2, and a nut 32 that is threadedly connected to the limiting bolt 31. The limiting bolt 31 passes through the hook-shaped suspension rod 21 in the horizontal direction. The head of the limiting bolt 31 is located on the outside of the suspension rod 21 used to form the hook-shaped structure. The threaded tail end of the limiting bolt 31 passes through the two parts of the suspension rod 21 on both sides of the keel in sequence, and then extends out of the outside of the suspension rod 21 used to fix one end of the straight pull rod 22. The nut 32 is threadedly connected to the threaded tail end of the limiting bolt 31 and abuts against the outside of the suspension rod 21 used to fix one end of the straight pull rod 22. The limiting bolt 31 closes the opening of the hook-shaped structure formed between the two ends of the suspension rod 21 and isolates the keel within the enclosed area of ​​the suspension rod 21 above the limiting bolt 31. A notch 23 is formed between the bottom end of the suspension rod 21 and the top end of the straight pull rod 22. The notch 23 is formed between one end of the suspension rod 21 bent to form a hook-shaped structure and the top end of the straight pull rod 22. The outer wall of the limiting bolt 31 is located above the notch 23 and is isolated between the keel and the notch 23. By forming the notch 23 between the end of the suspension rod 21 and the top end of the straight pull rod 22, the hook-shaped suspension rod 21 can have a larger elastic deformation, which is convenient for the installation of the keel and can increase the abutment force between the limiting bolt 31 and the nut 32 through the elasticity of the suspension rod 21 itself, thereby increasing the friction between the two and improving the stability of the locking member 3.

[0037] In this embodiment, the bearing member 1 is inserted into the top opening of the aluminum square tube along the side end opening of the aluminum square tube, so that the top plate 111 is located above the top opening of the aluminum square tube and the bottom plate 113 is located below the top opening of the aluminum square tube (i.e., inside the aluminum square tube). At this time, the reinforcing plate 112 is located in the opening area of ​​the aluminum square tube, and the two ends of the reinforcing plate 112 are respectively located on the upper and lower sides of the top opening of the aluminum square tube. The suspension rod 21, which has not yet been connected to the limit bolt 31, is placed on the keel. The bearing member 1 with the aluminum square tube clamped is suspended in the air by the suspension rod 21 and the straight rod 22. By moving the suspension rod 21 along the keel or moving the bearing member 1 along the aluminum square tube, the position and posture of the aluminum square tube relative to the keel can be changed. After the adjustment is completed, the limit bolt 31 is passed through the suspension rod 21 and locked by the nut 32 threaded thereon to complete the installation of the aluminum square tube. It is worth mentioning that the contact force of the nut 32 on the suspension rod 21 can be changed by changing the position of the nut 32 on the limit bolt 31, thereby changing the hook bending angle of the suspension rod 21 and changing the size of the internal enclosed space of the suspension rod 21. For example, when hanging on a keel with a smaller outer diameter, the hook bending angle of the suspension rod 21 is increased to reduce the hook enclosed area of ​​the suspension rod 21, reduce the gap between the keel and the inner wall of the suspension rod 21, and reduce the relative position of the suspension rod 21 on the keel. The possibility of displacement or deflection of the keel; similarly, for keels with a larger outer diameter, the hook-shaped bending angle of the suspension rod 21 is reduced to obtain a larger internal enclosed space of the suspension rod 21, so that the side wall of the hook-shaped bending part of the suspension rod 21 can fit with the outer wall of the keel over a larger area, thereby increasing the friction between the suspension rod 21 and the keel, reducing the deflection or displacement of the suspension rod 21, reducing the pressure on the suspension rod 21 or the keel, reducing the possibility of deformation of the suspension rod 21 or the keel, and reducing safety hazards.

[0038] In an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 4 A stabilizing member 33 is fixed on the suspension rod 21 for contacting the keel in the horizontal direction.

[0039] For example, refer to Figure 1 and Figure 4The stabilizing member 33 has abutment ends 332 distributed at least on both sides of the keel, and the distance between the abutment ends 332 can be adjusted. The stabilizing member 33 includes an adjusting bolt 331 threadedly connected to the suspension rod 21. The threaded tail end of the adjusting bolt 331 serves as the abutment end 332 and extends into the area enclosed by the suspension rod 21 and the locking member 3. The head of the adjusting bolt 331 is located outside the hook-shaped structure formed by the bending of the suspension rod 21. By rotating the adjusting bolt 331, the length of the threaded tail end of the adjusting bolt 331, serving as the abutment end 332, extending into the area enclosed by the suspension rod 21 can be changed, thereby adapting to keels of different sizes. For example, after the suspension rod 21 is hung on a keel with a smaller outer diameter, the adjusting bolt 331 is rotated so that the threaded tail end of the adjusting bolt 331 serving as the abutting end 332 extends toward the interior of the area surrounded by the hook-shaped structure of the suspension rod 21 and abuts against the outer wall of the keel. The two adjusting bolts 331 provided on the opposite sides of the suspension rod 21 can respectively abut against the two opposite side walls of the keel and impose horizontal and circumferential limitations on the suspension rod 21, thereby reducing the possibility of changes in the posture and position of the suspension rod 21. Similarly, when the suspension rod 21 is hung on a keel with a larger outer diameter, the adjustment bolt 331 can be rotated so that ... When the keel is large, the adjusting bolt 331 is rotated so that the threaded tail end of the adjusting bolt 331 serving as the abutment end 332 moves toward the outside of the area surrounded by the hook structure of the suspension rod 21, but the threaded tail end of the adjusting bolt 331 is still located inside this area, so that the adjusting bolt 331 can avoid the larger keel while abutting against the side wall of the keel, and provide the suspension rod 21 with horizontal limitation and circumferential anti-torsion limitation, reducing the possibility of the aluminum square tube shaking relative to the keel along with the connecting rod 2, thereby reducing safety hazards.

[0040] In other embodiments, in order to improve the connection stability of the adjusting bolt 331 on the suspension rod 21 and reduce the possibility of the adjusting bolt 331 loosening due to external force, a nut 32 can be threaded on the entity of the adjusting bolt 331 between the head of the adjusting bolt 331 and the outer wall of the suspension rod 21, and the nut 32 can be made to abut against the outer wall of the suspension rod 21, thereby increasing the friction between the adjusting bolt 331 and the suspension rod 21 and reducing the possibility of the adjusting bolt 331 loosening, thereby failing to limit the effect of the suspension rod 21.

[0041] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
