Description

Technical Field

[0001] This utility model relates to the field of trusses, and more specifically, to a modular movable truss. Background Technology

[0002] In the field of stage equipment, trusses play a crucial role, primarily used to install stage lights, screens, and other equipment, creating diverse atmospheres tailored to different performance themes through lighting combinations. Currently, in the actual operation of truss stage construction, welding or threaded connections are commonly used for fixing. However, this traditional construction method requires a large amount of truss material when building a fixed stage, and the construction process is cumbersome and complex. This not only increases labor and time costs but also demands a high level of technical skill from the builders, making it unsuitable for repeated use. Moreover, once the truss is completed, its shape is fixed, making it difficult to flexibly adjust it according to actual needs.

[0003] With the increasing diversity of stage performance formats, the demands for flexibility and dynamism in stage lighting have also risen, requiring movable lighting fixtures in many scenarios. However, existing fixed trusses cannot meet this need, making it difficult to freely move the lighting fixtures according to actual changes in stage design. Therefore, the market urgently needs a truss that can guarantee both sturdiness and allow for high degree of freedom of adjustment and positional movement, in order to better install lighting fixtures and adapt to diverse stage design requirements. Utility Model Content

[0004] To overcome at least one of the defects of the prior art, this utility model provides a modular movable truss that uses modular installation units to adjust the height of the light frame, and the light frame components can be horizontally spliced ​​together, adapting to the stage lighting installation needs of various stage designs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: to provide a rotatable truss stage device, including at least one set of lighting frame assemblies, wherein the lighting frame assembly includes a base plate and a plurality of mounting units that are vertically spliced ​​and fixedly installed on the base plate, wherein the mounting unit has a first horizontal bar and two vertical bars respectively connected to the two ends of the first horizontal bar, wherein the end of the vertical bar closer to the first horizontal bar is the first end and the other end is the second end, wherein the mounting unit is detachably connected to the second end of another mounting unit through the first end to complete the vertical splicing.

[0006] The base plate provides sufficient support strength for the vertically assembled mounting units. The height of the lighting frame assembly can be adjusted by freely combining the number of mounting units. The lighting fixtures are installed on the first horizontal bar or the vertical bar of the mounting unit, adapting to various installation requirements. After the performance, the mounting units can be disassembled and stored, facilitating both storage and transportation. Furthermore, the structure of this design also improves the assembly and disassembly efficiency of the truss.

[0007] Furthermore, it also includes connecting rods. The lighting truss assembly comprises multiple sets, and at least one adjacent mounting unit of each adjacent lighting truss assembly is connected via the connecting rods to complete the lateral splicing of several sets of lighting truss assemblies. This lateral splicing method allows for flexible adjustment of the truss width, enabling it to adapt to stage scenes with varying width requirements.

[0008] Furthermore, the first end of the mounting unit is fixedly connected to the second end of another mounting unit via a pin and a fastener. Using the pin and fastener to fix adjacent mounting units ensures a secure and stable connection while facilitating quick assembly / disassembly and reuse.

[0009] Furthermore, at least one reinforcing rod connects the first horizontal bar and the vertical bar. This strengthens the connection between the first horizontal bar and the vertical bar, ensuring the stability of the mounting unit and guaranteeing the secure installation of the lighting fixture.

[0010] Furthermore, the two vertical bars in the mounting unit located away from the substrate are connected by a second horizontal bar. This further strengthens the support structure of the lamp holder assembly, and the lamp can be suspended from the second horizontal bar, increasing the number of mounting positions for the lamp.

[0011] Furthermore, the vertical bar and the second horizontal bar are connected by a six-way connector. This allows for flexible multi-angle connections and stable assembly with other truss components, meeting the needs of constructing complex stage truss structures.

[0012] Furthermore, it also includes a support rod, one end of which is hinged to the base plate, and the other end is supported and connected to the assembled mounting unit located in the middle. For the lamp holder assembly with a certain height, using the support rod to provide auxiliary support to the mounting unit can further enhance the stability of the lamp holder assembly.

[0013] Furthermore, there are two support rods, and a clamping member for holding the vertical rod is pivotally connected to one end of the support rod near the mounting unit. The open end of the clamping member has an adjusting screw for adjusting the size of the opening. By adjusting the opening of the clamping member with the adjusting screw, the vertical rod can be easily clamped or released, making the operation simple.

[0014] Furthermore, pulleys are provided around the bottom of the base plate to facilitate the movement of the truss.

[0015] Furthermore, the length of the vertical rod is greater than or equal to that of the first horizontal rod. Since lamps generally have a certain height, and the lamp head typically rotates around the support base during operation, requiring more height space, this design provides sufficient installation space for the lamp.

[0029] Preferably, the connecting rod 200 can be a straight rod or multiple connecting rods at angles to each other, so that the lighting frame assemblies 100 can be set at various angles to adapt to various stage scenes.

[0030] In a preferred embodiment of this utility model, the first end 123 of the mounting unit 120 and the second end 124 of another mounting unit 120 are fixedly connected by a pin 310 and a buckle 320.

The operation is simple.

[0032] In a preferred embodiment of this utility model, at least one reinforcing rod 125 connects the first horizontal bar 121 and the vertical bar 122. This strengthens the connection between the first horizontal bar 121 and the vertical bar 122, ensuring the stability of the mounting unit 120 and guaranteeing the secure installation of the lamp.

[0033] In a preferred embodiment of this invention, the two vertical rods 122 in the mounting unit 120, which are located away from the substrate 110, are connected by a second horizontal rod 126. This further strengthens the support structure of the lamp holder assembly 100, and the lamp can be suspended from the second horizontal rod 126, increasing the number of mounting positions for the lamp.

[0034] In a preferred embodiment of this invention, the vertical rod 122 and the second horizontal rod 126 are connected by a six-way connector 127.

[0036] Preferably, the substrate 110 is provided with a mounting bracket 113 having a groove, and the support rod 130 has a protrusion 131 at one end near the substrate 110 that can be pivotally connected to the groove. After the protrusion 131 is inserted into the groove, it is pivotally fixed by the pin 310. Finally, the pin 320 is inserted into the insertion hole 311, so that the support rod 130 can rotate around the mounting bracket 113.

[0037] In a preferred embodiment of this utility model, there are two support rods 130.
