Description

Truss switching device Technical Field The utility model belongs to the technical field of truss connection, and particularly relates to a truss switching device. Background The truss is a structure formed by connecting rod pieces at two ends by hinges, and the truss is a plane or space structure which is composed of straight rods and is generally provided with triangular units, and the truss rod pieces are mainly subjected to axial tension or compression, so that the strength of materials can be fully utilized, the materials can be saved compared with the solid web beams when the span is large, the dead weight is reduced, and the rigidity is increased. The truss has the advantages that the rod is mainly subjected to tension or compression, the effect of materials can be fully exerted, and the truss structure is widely applied in various fields such as building construction, stage construction, exhibition and the like due to the advantages of high strength, light weight, convenience in assembly and disassembly and the like. However, when using the switching structure to connect the truss at present, often only can be connected with the bolt truss with the fixed position of switching structure installation on the main truss, when the different positions on the main truss need be connected to the different use scenes of coping with, be difficult to realize diversified connection demand in a flexible way. In view of this, the present utility model has been made. Disclosure of utility model In order to solve the problem that when the switching structure is used for connecting trusses at present, the fixed position of the switching structure on the main truss can only be connected with the bolt truss, and when the bolt truss is required to be connected at different positions on the main truss according to different use scenes, the basic conception of the technical scheme adopted by the utility model is as follows: The utility model provides a truss switching device, includes main truss, fixed bolster and switching frame, the connecting seat that the symmetry set up is installed to the fixed bolster bottom, fixedly be provided with the installation piece on the connecting seat, the mounting groove that the symmetry set up has been seted up to the fixed bolster bottom, the installation piece sets up inboard at the mounting groove, the connecting hole has been seted up on the installation piece, the connecting rod is provided with in the sliding of connecting hole, connecting rod tip position is provided with first screw thread section, first screw thread section extends to the fixed bolster outside, the spiro union is provided with first fastening nut on the first screw thread section, first fastening nut contacts with fixed bolster one side outer wall. As a preferred embodiment of the utility model, the fixed bracket is provided with a movable hole, the connecting hole is aligned with the movable hole, the diameter of the connecting hole is the same as that of the movable hole, and the first thread section passes through the movable hole and extends to the outer side of the fixed bracket.
