[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-7 A modular stage truss assembly structure includes a support frame 1, with connecting plates 2 fixedly connected to both ends of the support frame 1. A connector 3 is provided between the two connecting plates 2 for connecting them. The connector 3 includes a rotating plate 4, with several locking plates 5 fixedly connected to its side. An insertion interface 6 adapted to the rotating plate 4 is provided on the side of the connecting plate 2 away from the support frame 1. Several clearance openings 7, communicating with the outside and adapted to the locking plates 5, are provided on the inner wall of the insertion interface 6. A rotating locking groove 8, allowing the locking plates 5 to rotate, is provided at the bottom of the insertion interface 6. Two symmetrical rotating rods 9 are fixedly connected to the side of the rotating plate 4. The connecting plate 2 is located away from the support frame 1. One side of the support frame 1 is provided with a rotation opening 10 that communicates with the insertion interface 6 for the rotation of the rotating rod 9. The side of the connecting plate 2 near the support frame 1 is provided with a quick-stop unit 11 for limiting the rotation of the rotating rod 9. The quick-stop unit 11 includes several limit rods 12 that are inserted into the connecting plate 2. Both the connecting plate 2 and the rotating rod 9 are provided with insertion slots 13 that are adapted to the limit rods 12. One end of the limit rod 12 is fixedly connected to a pull plate 14. An elastic element 15 with elasticity is provided between the pull plate 14 and the connecting plate 2. The end of the rotating rod 9 away from the rotating plate 4 is provided with an insertion hole 22. One side of the locking plate 5 is inclined and adapted to the inner wall of the rotating locking slot 8.

[0030] Specifically, the stage truss in this embodiment is modularly produced. Connecting plates 2 are welded to both ends of the support frame 1. The length of the support frame 1 is varied, and a suitable truss size can be selected for modular installation according to the stage setup. When installing between two trusses, connectors 3 are used. The rotating plate 4 is inserted into the insertion interface 6, and several locking plates 5 are inserted into the clearance opening 7. Adjacent connecting plates 2 are then snapped onto the side of the rotating plate 4. At this time, the rotating rod 9 is located in the rotating opening 10 on the two adjacent connecting plates 2. By pulling the pull plate 14 away from the connecting plate 2, the elastic element 15 is stretched, and one end of the limiting rod 12 retracts into the insertion groove 13 on the connecting plate 2. By inserting the force rod that matches the insertion hole 22 into the insertion hole 22, and rotating the rotating rod 9 at the position of the rotating opening 10 through the force rod, the rotating rod 9 rotates. The plate 4 rotates, causing several locking plates 5 to rotate. The locking plates 5 rotate within the rotating locking groove 8, with one side of the locking plate 5 and the inner wall of the rotating locking groove 8 forming a suitable inclination. The several locking plates 5 rotate into the rotating locking groove 8, pressing and connecting the two connecting plates 2. When the insertion groove 13 on the rotating rod 9 aligns with the insertion groove 13 on the connecting plate 2, the pull plate 14 is released. At this time, the elastic element 15 contracts. The elastic element 15 is specifically a spring. One end of the limiting rod 12 is inserted into the insertion groove 13 on the rotating rod 9, limiting and fixing the position of the rotating rod 9, thus assembling the two connecting plates 2. When the two trusses need to be disassembled, the pull plate 14 is pulled again, rotating the rotating rod 9 in the opposite direction. After the locking plate 5 is in the position of the clearance opening 7, the two connecting plates 2 can be separated, facilitating the installation and disassembly of the modular stage truss, thereby improving the installation and disassembly efficiency of the overall truss.

[0031] As a technical optimization of this utility model, the side of the connecting plate 2 away from the support frame 1 is provided with a number of positioning grooves 16, and positioning pins 17 are inserted into the positioning grooves 16. When assembling the two trusses, the number of positioning pins 17 are inserted into the number of positioning grooves 16 on one connecting plate 2, and the positioning grooves 16 on the other connecting plate 2 are fitted onto the other end of the positioning pins 17 to limit the two connecting plates 2 and improve the stability of the two connecting plates 2 after connection.

[0032] As a technical optimization of this utility model, the connecting plate 2 has a plurality of connecting holes 19 on the side near the support frame 1. The side of the limiting rod 12 is fitted with a threaded ring 18 that is threadedly connected to the connecting holes 19. One side of the threaded ring 18 is fixedly connected to a polygonal locking block 20. The elastic element 15 is fitted between the limiting rods 12 and fixedly connected between the polygonal locking block 20 and the pull plate 14.

[0033] Specifically, the connecting plate 2 is provided with connecting holes 19 during production. When it is necessary to install it between trusses, it is connected to the connecting hole 19 by threaded ring 18. The threaded ring 18 is tightened by using a tool to clamp it on the side of the polygonal clamp block 20. The limiting rod 12 can then be used to limit the rotation rod 9, which facilitates the installation of the limiting rod 12 and the connecting plate 2, or the later disassembly and replacement of the limiting rod 12.

[0034] As a technical optimization of this utility model, the connecting plate 2 has several through holes 21 at one end near the support frame 1. The through holes 21 are connected to the positioning groove 16, and the middle diameter of the positioning pin 17 is larger than the diameters at both ends.

[0035] Specifically, the middle diameter of the positioning pin 17 is larger than the diameters at both ends, making it easier to insert the positioning pin 17 into the two positioning slots 16. When disassembling the truss later, the positioning pin 17 can be removed by using a top rod that is adapted to the through hole 21 and inserted into the through hole 21, and by using a hammer or other tools to knock the top rod. The positioning pin 17 is larger in the middle and smaller at both ends, making it easier to remove the positioning pin 17.

[0036] As a technical optimization of this utility model, a pressing angle 23 adapted to the end of the limiting rod 12 is provided on one side of the rotating rod 9. A rounded corner adapted to the pressing angle 23 is provided on the end of the limiting rod 12 away from the pull plate 14. By setting the pressing angle 23, it is not necessary to pull the pull plate 14 when rotating the rotating rod 9. The pressing angle 23 presses one end of the limiting rod 12, and the end of the limiting rod 12 is pressed into the insertion groove 13 on the connecting plate 2. When the insertion groove 13 on the rotating rod 9 moves to the position aligned with the insertion groove 13 on the connecting plate 2, the tension of the elastic element 15 automatically drives one end of the limiting rod 12 to insert into the insertion groove 13 on the rotating rod 9, which makes it more convenient to assemble the two trusses.
