[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 A snap-fit ​​aluminum square tube includes an aluminum square tube body 1. The two ends of the aluminum square tube body 1 are respectively provided with a first end 2 and a second end 3. The outer wall of the first end 2 fits the contour of the inner wall of the second end 3. Therefore, when the first end 2 and the second end 3 of two sets of aluminum square tube bodies 1 are aligned, the first end 2 can be inserted into the interior of the second end 3. A metal spring 4 is provided on the outer surface of the first end 2. The metal spring 4 is made of brass and welded to the first end 2, possessing good elasticity and plasticity. The metal spring 4 gradually expands outward from the outer end to the inner end of the first end 2. During the process of inserting the first end 2 into the interior of the second end 3, the metal spring 4 will contract inward under the squeezing action of the inner wall of the second end 3. A groove 5 is provided on the surface of the second end 3. When the first end 2 is fully inserted... When the metal spring 4 is inserted into the second end 3, it will just move to the position of the slot 5. At this time, the metal spring 4 will not contact the inner wall of the second end 3 and will no longer be subjected to inward squeezing. The metal spring 4 will expand outward and spring back into the slot 5. The slot 5 is provided with an auxiliary pressing component, which includes a threaded groove 6 on the slot 5 and a bolt 7 threaded into the threaded groove 6. The end of the bolt 7 is provided with a knob, which can control the bolt 7 to rotate. The bolt 7 can be moved towards the inside or outside of the slot 5 under the driving action of the threaded groove 6. When the metal spring 4 is inserted into the slot 5, by controlling the bolt 7 to move towards the inside of the slot 5, the metal spring 4 can be pressed inward, thereby controlling the metal spring 4 to retract inward again under the squeezing action.

[0022] By aligning the first end 2 and the second end 3 of the two sets of aluminum square tube bodies 1, the end of the first end 2 can be inserted into the interior of the second end 3. During this process, the metal spring 4 on the first end 2 will be squeezed and retracted inward by the second end 3. When the first end 2 is fully inserted into the interior of the second end 3, the two sets of aluminum square tube bodies 1 will be completely connected. At the same time, the metal spring 4 on the first end 2 will be aligned with the slot 5 on the second end 3. Since the metal spring 4 is no longer in contact with the inner wall of the second end 3, it will expand outward and spring back into the slot 5. The outwardly expanding and springing metal spring 4 will be locked together with the slot 5. At this time, under the restriction of the metal spring 4 and the slot 5, the first end 2 cannot slide outward from the second end 3, thus allowing the two sets of connected aluminum square tube bodies 1 to be spliced ​​and fixed. Together, by rotating bolt 7, it can be controlled to move inward toward the slot 5 and press the metal spring 4 inward to retract, so that the metal spring 4 no longer extends into the slot 5, thereby releasing the latching state between the metal spring 4 and the slot 5, allowing the first end 2 to slide outward toward the second end 3, thus enabling the two sets of aluminum square tube bodies 1 to be disassembled and separated. It can be seen that by inserting the first end 2 and the second end 3 of the two sets of aluminum square tube bodies 1 together, the two sets of aluminum square tube bodies 1 can be spliced ​​and fixed together under the latching action of the metal spring 4 and the slot 5. Rotating bolt 7 can press the metal spring 4 inward to release the latching state between the metal spring 4 and the slot 5, allowing the two sets of aluminum square tube bodies 1 to be separated from each other, thus enabling convenient and quick splicing or disassembly of the two sets of aluminum square tube bodies 1, effectively saving construction time.

[0023] For further details, please refer to Figure 1-4 An obstacle avoidance hole 8 is provided on the first end 2, located inside the metal spring 4. The outline of the obstacle avoidance hole 8 is slightly larger than that of the metal spring 4. When the metal spring 4 is pressed inward, the metal spring 4 can be pressed into the interior of the first end 2 through the obstacle avoidance hole 8, thereby avoiding obstruction of the inward contraction of the first end 2.

[0024] For further details, please refer to Figure 1-4 The metal springs 4 and the slots 5 are arranged in two opposing sets on both sides of the first end 2 and the second end 3. When the first end 2 is fully inserted into the interior of the second end 3, the two sets of metal springs 4 and slots 5 can engage with each other on both sides of the first end 2 and the second end 3, ensuring the splicing stability between the two sets of aluminum square tube bodies 1.

[0025] For further details, please refer to Figure 1-4The sidewall edge of the first end 2 has a rounded corner structure. When the first end 2 is inserted into the inside of the second end 3, it can effectively prevent the edge corner of the first end 2 from generating a large friction force between the edge corner of the first end 2 and the inner wall of the second end 3, so that the first end 2 can slide more smoothly inside the second end 3. In addition, the end of the second end 3 is provided with a notch 9. When the first end 2 is inserted into the inside of the second end 3, it can reduce the contact area between the second end 3 and the metal spring 4 on the first end 2, thereby reducing the contact friction force between the metal spring 4 and the inner wall of the second end 3, and further enabling the first end 2 to slide smoothly into the inside of the second end 3.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
