Example Embodiment
[0037] Example 1: A connection assembly of closed-loop pipe and plate, such as Figure 1-2 , Including a cylindrical connecting column 1, one end of the connecting column 1 is provided with a rectangular movable groove 11, a rotating shaft 2 is fixed in the movable groove 11, and a rectangular force block 3 is sleeved on the rotating shaft 2 to receive the force. The center of the block 3 deviates from the center of the shaft 2. As the force-bearing block 3 has a uniform texture, its center of gravity and center are at the same end of the shaft 2; when the force-bearing block 3 and the connecting column 1 are on the same straight line, the center of gravity of the force-bearing block 3 is close The bottom of the movable groove 11. The length of the force receiving block 3 is greater than the diameter of the connecting column 1, so that after the force is rotated, the movable grooves 11 at both ends can abut the inner wall of the connecting hole 61 on the closed loop pipe 6; the...
Example Embodiment
[0043] Embodiment 2: A connection assembly of closed-loop pipe and plate, such as Figure 5 The difference from Embodiment 1 is that a guide part 34 is fixed on the side of the force receiving block 3 close to the cut 32. The cross section of the guide part 34 is a right-angled triangle, and the slope of the guide part 34 and the slope of the cut 32 face the same direction.
[0044] Such as Figure 4 , A blocking member 13 is fixed on the inner side wall of the movable groove 11 near the bottom of the groove. The blocking member 13 is a cylindrical protrusion that abuts the side wall adjacent to the force receiving surface 31 in the force receiving block 3; the blocking member 13 is formed by It is made of rubber and is glued to the side wall of the movable groove 11. When the force receiving block 3 abuts against the blocking piece 13, the blocking piece 13 is compressed, and the force receiving block 3 cannot be deflected under the condition of only gravity. When the force recei...
Example Embodiment
[0049] Embodiment 3: A connection assembly of a closed-loop pipe fitting and a plate. The difference from Embodiment 1 lies in: Figure 7 , A limit post 14 is fixed in the movable groove 11, and when the force receiving block 3 and the connecting post 1 are on the same straight line, the limit post 14 abuts the force receiving surface 31.
[0050] When inserting the installation hole 71, hold the connecting column 1, the force receiving surface 31 of the force receiving block 3 faces downwards, and when the force receiving block 3 extends into the closed loop pipe fitting 6, rotate 180 degrees so that the force receiving surface 31 of the force receiving block 3 Upward, at this time, the force receiving block 3 rotates inside the closed loop pipe 6 due to the eccentricity of gravity. Pull back the connecting column 1 so that the force-receiving surface 31 abuts against the inner wall of the connecting hole 61 of the closed-loop tube 6, sleeve the elastic washer 4 on the connecting...
