Technical Field

[0001] The utility model relates to the technical field of trusses, in particular to a light combined assembled steel structure truss. Background Art

[0002] Truss: A structure composed of rods connected to each other by hinges at both ends. The truss is a plane or spatial structure composed of straight rods and generally has triangular units. The truss rods mainly bear axial tension or pressure, so as to make full use of the strength of the material. When the span is large, it can save materials compared to solid beams, reduce deadweight and increase rigidity. Commonly used ones are steel trusses, reinforced concrete trusses, prestressed concrete trusses, wooden trusses, steel and wood composite trusses, and steel and concrete composite trusses.

[0003] For example, a light assembled steel structure truss with application number 202221351913.4 can adjust the overall length of the truss body and the support frame through the coordinated use of bolts, second threaded holes, third threaded holes, threaded rods, support blocks, first threaded holes, support frames, truss bodies, auxiliary trusses and first movable holes, thereby adapting to different sizes of inkjet printing cloths. However, the preset installation holes at both ends of the device are relatively fixed, and it is difficult to adjust the installation hole positions to the appropriate size according to the actual hole spacing of the installation plate, which has great installation limitations.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a light composite assembled steel structure truss is proposed. Utility Model Content

[0007] Preferably, a limiting groove is provided inside the slide groove, and a limiting block is fixedly connected to the outer surface of the assembly hole seat, and the limiting block is slidably connected to the inside of the limiting groove.

[0008] Preferably, a plurality of insertion holes are provided on the outer circumferential surface of the mounting frame, connecting sleeves are fixedly connected to the inner surfaces of both ends of the truss body, insert rods are slidably connected inside the two ends of the truss body, and a cylindrical rod is rotatably connected inside the connecting sleeves.

[0013] 1. The utility model is provided with a truss body, a mounting frame, a slide groove, a limit groove, a screw rod, a nut seat, and an assembly hole seat.

The rotation of the screw rod can drive the nut seat to slide, and drive the assembly hole seat to slide together with the limit position inside the slide groove, so that the assembly hole seat fits the mounting hole position corresponding to the actual mounting plate. This design can reduce the limitation of actual installation, fit the mounting plates with different hole pitches, and facilitate the operator to install;

[0014] 2. The utility model adjusts the extension length of the mounting frame inside the truss body through the arrangement of the jack, the connecting sleeve, the insertion rod, the barrel rod, the linkage rod, the adjusting knob, the shaft rod, and the volute spring. The adjusting knob can be rotated to stretch the volute spring, and the elliptical transmission plates at both ends of the barrel rod can drive the insertion rod to retract through the linkage rod, so that the insertion rod is separated from the inside of the jack. At this time, the extension length of the mounting frame can be adjusted, the adjusting knob is loosened, the volute spring is reset, and the barrel rod can insert the insertion rod into the inside of the jack through the linkage rod to lock the entire mounting frame. This design can achieve the technical effect of multi-structure linkage locking in one step, which is convenient for the operator to adjust the extension length of the mounting frame.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0021] like Figure 1-Figure 2 The nut seat 5 is driven by the screw rod 4 to slide in the groove 3, and the nut seat 5 is driven by the screw rod 4 to slide in the groove 3, so that the nut seat 5 can slide in the groove 3.

[0022] like Figure 1-Figure 4 As shown, a plurality of insertion holes 7 are provided on the outer circumferential surface of the mounting frame 2, and connecting sleeves 8 are fixedly connected to the inner surfaces of both ends of the truss body 1, and plug rods 9 are slidably connected inside the two ends of the truss body 1, and a cylindrical rod 10 is rotatably connected inside the connecting sleeve 8 to improve the self-locking ability. The cylindrical rod 10 rotates within the connecting sleeve 8, and both ends of the cylindrical rod 10 are designed with elliptical transmission discs.

[0023] Furthermore, both ends of the cylindrical rod 10 are rotatably connected to two linkage rods 11, and one end of the linkage rod 11 is rotatably connected to one end of the insertion rod 9, and the end surface of the insertion rod 9 can be provided with a rounded corner design.

[0024] Furthermore, one end of the tube rod 10 extends to the outer surface of one side of the truss body 1 and is fixedly connected to an adjustment knob 12, and the inner surface of the truss body 1 passes through the interior of the tube rod 10 and is fixedly connected to an axis rod 13. The outer circular surface of the adjustment knob 12 can be added with an anti-slip pattern design to improve the contact friction during adjustment.

[0025] Furthermore, a spiral spring 14 is fixedly connected to the outer circular surface of the shaft rod 13, and one end of the spiral spring 14 is fixedly connected to the inner circular surface of the barrel rod 10.

[0026] Working principle: When using the light combined assembled steel structure truss, first, when assembling the truss body 1, the screw rod 4 can be rotated according to the hole spacing size of the actual mounting plate. The rotation of the screw rod 4 can drive the nut seat 5 to slide, and drive the assembly hole seat 6 to slide together with the limit position inside the slide groove 3, so that the assembly hole seat 6 fits the mounting hole position on the corresponding actual mounting plate. When adjusting the extension length of the mounting frame 2 inside the truss body 1, the adjusting knob 12 can be rotated to stretch the spiral spring 14. The elliptical transmission plates at both ends of the barrel rod 10 can drive the insertion rod 9 to retract through the linkage rod 11, so that the insertion rod 9 is separated from the inside of the socket 7. At this time, the extension length of the mounting frame 2 can be adjusted, the adjusting knob 12 is loosened, the spiral spring 14 is reset, and the barrel rod 10 can insert the insertion rod 9 into the inside of the socket 7 through the linkage rod 11 to lock the entire mounting frame 2. This is the working principle of the light combined assembled steel structure truss.
