[0036] Protective plates 36 are movably connected to both sides of the connecting plate 24, and a limiting rod 37 is installed on the inner side of the protective plate 36. A rotating plate 26 is installed on the end of the fourth threaded rod 25, and a limiting groove 27 is provided on the inner side of the rotating plate 26. The limiting groove 27 and the limiting rod 37 are movably connected. A second square groove 11 is provided inside the connecting rod 6, and a connecting block 12 is symmetrically installed inside the second square groove 11. A second round rod 13 is rotatably connected between the two connecting blocks 12, and a second torsion spring 14 is installed between the two connecting blocks 12. A steel cable 15 is installed on the side of the connecting rod 6, and a first sliding groove 7 is provided on the inner side of the steel frame body 1. The first sliding groove 7 is slidably connected to the circular plate 8. A fixed groove 10 is provided on the inner side of the first sliding groove 7. The circular plate 8 and the first threaded rod 9 are threadedly connected, and the first threaded rod 9 and the fixed groove 10 are movably connected.

[0037] A first square groove 3 is provided on the side of the steel frame body 1, and a first round rod 4 is installed on the inner side of the first square groove 3. The first round rod 4 is rotatably connected to the connecting rod 6, and a first torsion spring 5 is installed on the side of the connecting rod 6. The side of the first torsion spring 5 away from the connecting rod 6 is fixedly connected to the inner wall of the first square groove 3. Multiple connecting rods 6 are respectively located around the steel frame body 1, and multiple connecting rods 6 are all on the movement trajectory of the circular plate 8. A second sliding groove 17 is provided inside the support plate 16, and a first sliding block 18 is slidingly arranged inside the second sliding groove 17.

[0039] In this embodiment, when the steel frame body 1 needs to be used, the mounting hole on the base 2 is first connected to the receiving platform through the fixing bolts. At this time, the first threaded rod 9 can be rotated, and the first threaded rod 9 is separated from the fixing groove 10 by the force generated by rotating the first threaded rod 9. Then, the return plate 8 is slid along the first sliding groove 7 to move the return plate 8 downward to squeeze the connecting rod 6, so that the connecting rod 6 is rotated along the first round rod 4 as the center. At this time, the first torsion spring 5 contracts until it drives the support plate 16 to be parallel to and in contact with the ground. At this time, the position of the support plate 16 can be adjusted according to the support conditions of the ground. First, the second threaded rod 20 is rotated to The force generated when the rod 20 rotates drives the first sliding block 18 to move up and down along the third round rod 19, and drives the support plate 16 to move, so that the support plate 16 is in close contact with the ground. At the same time, the third threaded rod 23 can be rotated, and the force generated by rotating the third threaded rod 23 causes the second sliding block 22 to move along the third sliding groove 21, and at the same time, the first sliding block 18 moves along the second sliding groove 17, so as to realize the horizontal movement of the support plate 16, so that the support area of ​​the steel frame body 1 can be expanded through the support plate 16, thereby ensuring the bottom stability of the steel frame body 1, and the support area can be adjusted according to actual conditions, thereby enhancing the adaptability of the device;

[0040] When strong shaking occurs, if the connecting rod 6 is subjected to a bending force, the connecting rod 6 can be broken through the second square groove 11. At this time, the two connecting blocks 12 are elastically connected through the second round rod 13, the second torsion spring 14 and the steel cable 15, so that the preset weak point will first break. This design can absorb and disperse a large amount of vibration energy, thereby reducing the overall vibration response of the steel frame body 1. After breaking, the second round rod 13, the second torsion spring 14 and the steel cable 15 can quickly take effect, absorb and consume the remaining vibration energy through their deformation, further reduce the vibration amplitude of the structure, and improve the stability of the steel frame body 1. Example

[0041] like Figure 1 - Fig.10 As shown, based on the first embodiment, the connecting plate 24 is threadedly connected to the fourth threaded rod 25, the fourth threaded rod 25 is threadedly connected to the square plate 28, first L-shaped rods 29 are installed on both sides of the square plate 28, and the ends of the two first L-shaped rods 29 away from the square plate 28 are fixedly connected to the fixing plate 30, and the fixing plate 30 is slidably connected to the connecting plate 24;

[0042] A second L-shaped rod 31 is installed on the upper part of the square plate 28, and the end of the second L-shaped rod 31 away from the square plate 28 is fixedly connected to the limit plate 32, and the limit plate 32 is slidably connected to the connecting plate 24. Rings 33 are installed on both sides of the connecting plate 24, and a spring 34 is installed inside the ring 33. A movable rod 35 is installed at the end of the spring 34 away from the connecting plate 24, and the end of the movable rod 35 away from the spring 34 is fixedly connected to the protective plate 36. The size of the opening of the protective plate 36 is adapted to the size of the rotating plate 26, and the limit groove 27 is adapted to the multi-angle limit rod 37.

[0043] In this embodiment, when the steel frame body 1 needs to be connected to the upper connecting piece, the connecting piece is first moved to the inner side of the connecting plate 24, and then the rotating plate 26 is pulled to move the rotating plate 26 in a direction away from the connecting plate 24, so that the connecting plate 24 is stretched until the protective plate 36 no longer wraps the rotating plate 26, and then the fourth threaded rod 25 is rotated by the rotating plate 26. The force generated by the rotation of the fourth threaded rod 25 can drive the square plate 28 to move in a direction close to the connecting plate 24, and at the same time drive the first L-shaped rod 29 and the second L-shaped rod 31 to move. When the first L-shaped rod 29 moves, it drives the fixing plate 30 to squeeze the connecting piece, thereby achieving fixation, and the second L-shaped When the rod 31 moves, it can drive the limit plate 32 to move to the top of the connecting piece to achieve the limit. After the steel frame body 1 and the connecting piece are connected, the rotating plate 26 can be loosened, and the spring 34 in the stretched state is reset, and at the same time, the movable rod 35 is driven to move to the inside of the ring 33. At this time, the protective plate 36 wraps around the rotating plate 26, and the limit rod 37 is inserted into the limit groove 27 to achieve the limit of the rotating plate 26. In this way, the steel frame body 1 and the connecting piece can be quickly fixed and limited. The fixed and limited connection simultaneously limits the rotating plate 26 through the protective plate 36, thereby avoiding accidental loosening or falling off, and improving the connection stability between the steel frame body 1 and the connecting piece.
