The steel component system has comprehensive advantages such as light self-weight, factory manufacturing, fast installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. Some steel components need to use connection structures to connect the steel components together during use.

[0003] There are still some problems with common quick-disassembly connection structures for steel components. For example, when using connection processing, it is necessary to connect two groups of steel components together. When connecting steel components, it is not convenient to quickly install and disassemble the steel components, which easily affects the efficiency of installation and disassembly.

[0026] The limiting component includes a limiting rod 7, a limiting groove 8 and a connecting spring 14. Inside the protective shell 4, there is a fixed connection with a fixing plate 19. At both ends of the fixing plate 19, there are fixed connections with the connecting spring 14. Inside the connecting spring 14, there is a damper 15. At the outer end of the connecting spring 14, there is a fixed connection with a mounting plate 20. At the bottom end of the mounting plate 20, there is a fixed connection with a connecting rod 3. At the outer end of the mounting plate 20, there is a fixed connection with the limiting rod 7. Inside the connecting frame 2, there is a limiting groove 8 opened;

[0027] At both ends of the mounting frame 1, there are respectively a first steel member 9 and a second steel member 18. The first steel member 9 and the second steel member 18 are arranged inside the connecting frame 2. The limiting rod 7 is embedded inside the limiting groove 8, and the limiting rod 7 and the limiting groove 8 cooperate with each other;

[0028] Specifically, as Figure 1 、 Figure 2 and Figure 3 shown, when it is necessary to disassemble the first steel member 9 and the second steel member 18, pull the connecting rod 3. The connecting rod 3 pulls the mounting plate 20 to make the mounting plate 20 squeeze the connecting spring 14, so that the limiting rod 7 can be disengaged from the inside of the limiting groove 8, and the first steel member 9 and the second steel member 18 lose their fixation. When the first steel member 9 and the second steel member 18 lose their fixation, the first steel member 9 and the second steel member 18 can be quickly disassembled, which can save the time for disassembling the first steel member 9 and the second steel member 18. The damper 15 can limit the connecting spring 14 to prevent the connecting spring 14 from shaking too much.

[0029] Embodiment 2: At the top end of the protective shell 4, there is a fixed connection with a connecting block 5. At the top end of the connecting block 5, there is a fixed connection with a slider 21. At the top end inside the slider 21, there is a rolling groove 23 opened. Inside the rolling groove 23, there is a rolling ball 22 arranged. At the top end inside the mounting frame 1, there is a limiting sliding groove 6 opened. At both ends of the mounting frame 1, there are reserved grooves opened. The slider 21 is arranged inside the limiting sliding groove 6. The slider 21 slides inside the limiting sliding groove 6. The rolling ball 22 rolls inside the rolling groove 23. The limiting rod 7 slides left and right inside the reserved groove. There are two groups of protective shells 4;

[0030] Specifically, as Figure 1 and Figure 4 shown, when it is necessary to adjust the position of the protective shell 4, push the protective shell 4. The connecting block 5 at the top end of the protective shell 4 will drive the slider 21 to slide inside the limiting sliding groove 6. The limiting sliding groove 6 and the slider 21 can support and limit the protective shell 4 through the connecting block 5 to prevent the protective shell 4 from falling off during sliding. The rolling ball 22 can reduce the friction between the slider 21 and the limiting sliding groove 6. By adjusting the position of the protective shell 4, it is convenient to connect the first steel member 9 and the second steel member 18 with different lengths.

[0031] Embodiment 3: A threaded groove 12 is provided on the inner side wall of the connecting frame 2 near the outer end. A threaded rod 10 is arranged inside the threaded groove 12. One end of the threaded rod 10 near the outer part is fixedly connected with a turning handle 11. One side of the threaded rod 10 near the middle is fixedly connected with a rotating block 16. A limiting plate 13 is arranged inside the connecting frame 2. A rotating groove 17 is provided inside the limiting plate 13. The threaded groove 12 and the threaded rod 10 cooperate with each other, and the rotating block 16 rotates inside the rotating groove 17;

[0032] Specifically, as Figure 2 and Figure 3 shown, rotate the turning handle 11. The turning handle 11 drives the rotating block 16 to rotate inside the rotating groove 17, so that the rotating block 16 pushes the limiting plate 13 to adjust the position of the limiting plate 13, thereby facilitating the limiting of the first steel member 9 and the second steel member 18 of different sizes.

[0033] Working principle: When the present utility model is in use, push the protective shell 4. The connecting block 5 at the top of the protective shell 4 will drive the slider 21 to slide inside the limiting sliding groove 6. The limiting sliding groove 6 and the slider 21 can support and limit the protective shell 4 through the connecting block 5 to prevent the protective shell 4 from falling off during sliding. The ball 22 can reduce the friction between the slider 21 and the limiting sliding groove 6. By adjusting the position of the protective shell 4, it is convenient to connect the first steel member 9 and the second steel member 18 of different lengths. After adjustment, place the first steel member 9 and the second steel member 18 inside the connecting frame 2. After placing, loosen the connecting rod 3. The connecting spring 14 enables the limiting rod 7 to be embedded inside the limiting groove 8 to fix the first steel member 9 and the second steel member 18 flexibly. Rotate the turning handle 11. The turning handle 11 drives the rotating block 16 to rotate inside the rotating groove 17, so that the rotating block 16 pushes the limiting plate 13 to adjust the position of the limiting plate 13, thereby facilitating the limiting of the first steel member 9 and the second steel member 18 of different sizes. When it is necessary to disassemble the first steel member 9 and the second steel member 18, pull the connecting rod 3. The connecting rod 3 pulls the mounting plate 20 to make the mounting plate 20 squeeze the connecting spring 14, so that the limiting rod 7 can be disengaged from the inside of the limiting groove 8, and the first steel member 9 and the second steel member 18 are no longer fixed. When the first steel member 9 and the second steel member 18 are no longer fixed, the first steel member 9 and the second steel member 18 can be quickly disassembled, which can save the time for disassembling the first steel member 9 and the second steel member 18. The damper 15 can limit the connecting spring 14 to prevent the connecting spring 14 from shaking too much.
