The truss fixing connector is made of hard metal material as a whole and has high strength, such as steel material. The truss fixing connector includes a fixing plate 1, a clamping plate 3 and a fixing bolt 5. Connecting seats 2 are arranged at both the upper and lower ends of the fixing plate 1. The clamping plate 3 is rotatably connected to the connecting seat 2. After the fixing plate 1 and the clamping plate 3 are turned over and fitted together, half grooves are opened on the right side of the fixing plate 1 and the left side of the clamping plate 3. The half grooves on the fixing plate 1 and the clamping plate 3 form a truss clamping groove 4. A first through hole 8 is opened on the clamping plate 3, and second through holes 9 are opened on both the upper and lower sides of the fixing plate 1. When the fixing plate 1 and the clamping plate 3 are turned over and fitted together, the positions of the first through hole 8 and the second through hole 9 correspond to each other. The fixing bolt 5 includes a smooth shaft section 6 and a threaded section 7. The smooth shaft section 6 is a smooth rod body, and the threaded section 7 is arranged on the left side of the smooth shaft section 6. A force-applying rotating end is arranged at the right end of the smooth shaft section 6 for rotating the fixing bolt 5 through a wrench. The smooth shaft section 6 passes through the first through hole 8 and the second through hole 9, and the threaded section 7 extends to the left side of the fixing plate 1. A fixing nut 10 is screwed on the threaded section 7. The fixing nut 10 is located on the left side of the fixing plate 1, and a loosening prevention mechanism is arranged on the fixing nut 10.

[0023] The smooth shaft section 6 and the threaded section 7 are integrally formed, and the structure is stable.

[0024] The loosening prevention mechanism includes a convex block 11 and a loosening prevention bolt 12. The outer wall of the fixing nut 10 is fixedly connected with the convex block 11. A threaded hole 13 is opened on the convex block 11, and the loosening prevention bolt 12 is screwed in the threaded hole 13. The loosening prevention bolt 12 presses against the fixing plate 1.

[0025] The number of the convex blocks 11 is two, and the two convex blocks 11 are symmetrically distributed along the center of the fixing nut 10.

[0026] As shown in the Figure 4 drawing, the two trusses connected by the truss fixing connector include a transverse truss 14 and a longitudinal truss 15. The transverse truss 14 and the longitudinal truss 15 are vertically arranged. A connecting hole 16 is opened at the left end of the transverse truss 14, and the smooth shaft section 6 passes through the connecting hole 16. The rod body of the longitudinal truss 15 is located in the truss clamping groove 4.

[0027] Working principle: The transverse truss 14 and the longitudinal truss 15 are fixed through the truss fixing connector. The fixing plate 1 and the clamping plate 3 are turned and fitted so that the rod body of the longitudinal truss 15 is located in the truss clamping groove 4. Then, the clamping plate 3 and the fixing plate 1 are fixed through the fixing bolt 5, so that the corresponding longitudinal truss 15 located in the truss clamping groove 4 is connected. At the same time, during the fixing process of the fixing bolt 5, by passing the optical axis section 6 of the fixing bolt 5 through the connection hole 16 at the left end of the transverse truss 14, the first through hole 8 and the second through hole 9, the transverse truss 14 is connected, and thus the transverse truss 14 and the longitudinal truss 15 are fixed. The overall truss fixing connector has a simple and ingenious structure. It can well fix the truss, and at the same time, the installation and disassembly are relatively convenient, which can improve the efficiency of truss erection and disassembly. Through the setting of the anti-loosening mechanism, when the fixing nut 10 is installed, by screwing the anti-loosening bolt 12 on the convex block 11, the anti-loosening bolt 12 presses the fixing plate 1, which can improve the stability of the fixing nut 10, avoid loosening, and improve the use safety.
