Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 , the utility model provides a technical solution:

[0020] Embodiment 1:

[0021] like Figure 1-4 As shown, a Z-shaped steel purlin connection node structure includes a Z-shaped steel 1, one side of the Z-shaped steel 1 is provided with an L-shaped plate 2 for connecting the Z-shaped steel 1 with other structures, one side of the Z-shaped steel 1 is provided with a circular through hole 3, a movable rod 4 for connecting the Z-shaped steel 1 and the L-shaped plate 2 is installed inside the through hole 3, the length of the movable rod 4 is greater than the length of the through hole 3, and a connecting piece for fixing the movable rod 4 in the through hole 3 is installed on the L-shaped plate 2.

[0022] Embodiment 2:

[0023] The technical solution is basically the same as that of the first embodiment, except that Figure 2 As shown, the connecting piece includes a slot 5 opened on one side of the Z-shaped steel 1, a block 6 for inserting into the slot 5 is fixedly installed at one end of the movable rod 4, a spring 8 for pushing the movable rod 4 to move is installed on one side of the L-shaped plate 2, the spring 8 abuts against one side of the L-shaped plate 2, and one end of the spring 8 abuts against a circular block 7 for facilitating the staff to rotate the movable rod 4.

[0024] Embodiment three:

[0025] The technical solution is basically the same as that of the first embodiment, except that Figure 3 and Figure 4 As shown, the L-shaped plate 2 is internally rotatably connected with a circular sleeve 9 for secondary fixing the Z-shaped steel 1 and the L-shaped plate 2. The number of the circular sleeves 9 is set to two and the two circular sleeves 9 are arranged in a mirror-symmetrical manner with the L-shaped plate 2 as the center. A through groove 10 is opened on one side of the circular sleeve 9. A clamping column 12 for sliding connection inside the through groove 10 is fixedly installed on one side of the Z-shaped steel 1. A limiting ball 13 for preventing the clamping column 12 from falling off from the circular sleeve 9 is installed at one end of the clamping column 12.
