When the threaded rod is inserted into the installation groove, the insertion rod is released so that it can be inserted into the interior of the slot opened on the threaded rod under the elastic force of the first spring, thereby fixing the threaded sleeve and the threaded rod with the two pillars together. Then, the two threaded rods on the other threaded sleeve can be placed inside the fixing seats on the two pillars. Before placing them in, the corresponding clamping rod needs to be pulled outwards first. After insertion, the clamping rod is released so that it can be inserted into the interior of the slot opened on the threaded rod under the elastic force of the second spring, thereby fixing the threaded rod and the threaded sleeve to form a triangular structure with the pillar, making the structure more stable. When disassembling, it only needs to be reversed. By performing the above operations, the threaded sleeve and the threaded rod can be removed from the pillar, which is convenient and quick, and it is also convenient to connect multiple pillars according to actual needs. When it is necessary to adjust the height of the grid, it is only necessary to rotate the threaded sleeve to move it upward on the support rod, thereby supporting the pillar to move upward, thereby adjusting the height of the grid, which is convenient to use. When it is necessary to adjust the width, the threaded sleeve can be rotated to drive the two threaded rods with opposite threads to move, so as to adjust the distance between the two pillars, and the width can be adjusted. In addition, multiple pillars, threaded sleeves and threaded rods can be connected together through the above-mentioned installation steps, and the purpose of adjusting the width can also be achieved. When the grid is in use, each component can be quickly installed and disassembled, and the triangular structure is more stable.

DETAILED DESCRIPTION

[0022] See also Figure 1-3 ,

[0023] Embodiment 1: An adjustable steel structure grid comprises a pillar 1 and a threaded sleeve 2. Two fixing collars 3 are fixedly sleeved on the surface of the pillar 1. Both sides of the two fixing collars 3 are provided with mounting grooves 4. Threaded rods 5 are threadedly sleeved on both ends of the threaded sleeve 2. The mounting grooves 4 match one end of the threaded rod 5. Two movable grooves 6 are provided on the surfaces of the two fixing collars 3. Each movable groove 6 is connected to the corresponding mounting groove 4. A plug rod 7 is slidably connected inside each movable groove 6. A slot 8 is provided at one end of each threaded rod 5 located on the outer side of the threaded sleeve 2. The slot 8 matches the plug rod 7. A first spring 9 is fixedly sleeved on one end of each plug rod 7. A group of fixing seats 10 are fixedly connected on the front and back sides of the pillar 1. A sliding groove 11 is provided on the surface of each fixing seat 10. A clamping rod 12 is slidably connected inside each sliding groove 11. The clamping rod 12 matches the slot 8. A second spring 13 is fixedly sleeved on one end of the outer side of each clamping rod 12.

[0024] Embodiment 2: The difference between this embodiment and embodiment 1 is that, one end of the outer side of the two threaded rods 5 inside the top threaded sleeve 2 and one end of the outer side of the two threaded rods 5 inside the bottom threaded sleeve 2 are both threadedly sleeved with limiting blocks 14, so that the connection between the threaded rods 5 and the fixing ring 3 is tighter to avoid shaking.

[0025] Embodiment 3: The difference between this embodiment and embodiment 1 is that the two fixing seats 10 fixed on the same surface of the pillar 1 are oriented in opposite directions, so as to facilitate connecting multiple pillars 1 together and form a stable triangular structure through the threaded sleeve 2 and the threaded rod 5.

[0026] Embodiment 4: The difference between this embodiment and embodiment 1 is that the interior of the pillar 1 is hollow, and a support rod 15 is slidably sleeved inside the pillar 1. The surface of the support rod 15 is provided with an external thread 16, and the support rod 15 is threadedly sleeved with a threaded sleeve 17 through the external thread 16. The size of the threaded sleeve 17 is larger than that of the pillar 1, which facilitates the adjustment of the height of the pillar 1, thereby facilitating the adjustment of the height of the grid.

[0027] Embodiment 5: The difference between this embodiment and embodiment 1 is that the bottom end of the support rod 15 is fixedly connected with a mounting plate 18, and the surface of the mounting plate 18 is provided with mounting holes 19, so as to facilitate the fixing of the grid on the ground.

[0028] Embodiment 6: The difference between this embodiment and embodiment 1 is that the thread directions of the two threaded rods 5 threadedly sleeved inside each threaded sleeve 2 are opposite, so that the length of the two threaded rods 5 can be adjusted by rotating the threaded sleeve 2, thereby facilitating the adjustment of the width of the grid.

[0029] To sum up, when using the adjustable steel structure grid, the outer ends of the two threaded rods 5 on the threaded sleeve 2 are respectively inserted into the installation grooves 4 on the two fixing collars 3 on the two pillars 1. Before insertion, the corresponding insertion rod 7 needs to be pulled upwards. When the threaded rod 5 is inserted into the installation groove 4, the insertion rod 7 is released so that it can be inserted into the slot 8 opened on the threaded rod 5 under the elastic force of the first spring 9, thereby fixing the threaded sleeve 2 and the threaded rod 5 with the two pillars 1 together. Then, the two threaded rods 5 on the other threaded sleeve 2 can be placed inside the fixing seats 10 on the two pillars 1. Before placing them in, the corresponding clamping rod 12 must be pulled outwards first. After insertion, the clamping rod 12 is released so that it can be inserted into the slot 8 opened on the threaded rod 5 under the elastic force of the second spring 13, thereby fixing the threaded rod 5 and the threaded sleeve 2. A triangular structure is formed with the pillar, making the structure more stable. When disassembling, only the reverse operation is required. Through the above operation, the threaded sleeve 2 and the threaded rod 6 can be removed from the pillar 1, which is convenient and quick. At the same time, it is convenient to connect multiple pillars 1 according to actual needs. When it is necessary to adjust the height of the grid, it is only necessary to rotate the threaded sleeve 17 to make it move upward on the support rod 15, thereby supporting the pillar 1 to move upward, so as to adjust the height of the grid, which is convenient to use. When it is necessary to adjust the width, the threaded sleeve 2 can be rotated to drive the two threaded rods 5 with opposite threads to move, so as to adjust the distance between the two pillars 1, so as to adjust the width. In addition, multiple pillars 1, threaded sleeves 2 and threaded rods 5 can be connected together through the above installation steps, and the purpose of adjusting the width can also be achieved. When the grid is in use, each component can be quickly installed and disassembled. At the same time, the triangular structure is more stable, and the height and width of the grid can be adjusted according to actual needs, which is convenient to use.
