Description

Technical Field

[0001] This utility model belongs to the field of truss connection technology, specifically, it relates to a truss transition device. Background Technology

[0002] A truss is a structure made up of members connected to each other at both ends by hinges. A truss is a planar or spatial structure composed of straight members and generally has triangular units. Truss members mainly bear axial tension or compression, thus making full use of the strength of the material. When the span is large, it can save material, reduce self-weight and increase stiffness compared to solid beams.

[0003] The advantage of trusses is that their members primarily bear tension or compression, fully utilizing the material's potential. Truss structures are widely used in numerous fields such as building construction, stage construction, and exhibitions due to their high strength, light weight, and ease of assembly and disassembly. However, currently, when using transition structures to connect trusses, the transition structure is often only able to be installed at a fixed position on the main truss and connected to the pin truss. This makes it difficult to flexibly meet diverse connection needs when different application scenarios require connecting pin trusses at different positions on the main truss.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

The connecting seats have mounting blocks fixedly installed on them. The fixed support has symmetrically arranged mounting grooves at its bottom. The mounting blocks are located inside the mounting grooves and have connecting holes. A connecting rod is slidably arranged in the connecting holes. The end of the connecting rod has a first threaded section that extends to the outside of the fixed support. A first fastening nut is screwed onto the first threaded section and contacts one side of the outer wall of the fixed support.

[0007] In a preferred embodiment of this utility model, the fixed bracket is provided with a movable hole, the connecting hole is aligned with the movable hole and the connecting hole has the same diameter as the movable hole, and the first threaded segment extends through the movable hole to the outside of the fixed bracket.

[0008] In a preferred embodiment of this utility model, four adapters are fixedly provided on one side of the adapter frame, and the adapters are provided with adapter holes.

[0009] In a preferred embodiment of the present invention, four positioning rods are fixedly provided on one side of the adapter frame, and a second threaded section is provided at the end of each positioning rod.

[0010] In a preferred embodiment of this utility model, both the fixed bracket and the connecting seat are provided with positioning holes, the positioning rod is adapted to the positioning holes, and the positioning rod extends through the positioning holes to the outside of the fixed bracket and the connecting seat.

[0011] In a preferred embodiment of this utility model, a second fastening nut is screwed onto the second threaded section, and the second fastening nut contacts the outer wall of one side of the fixed bracket and the connecting seat.

[0012] Compared with the prior art, the present invention has the following advantages:
