Abstract

The invention provides a truss mechanism for performance. The truss mechanism comprises a base, a first arm rest and a second arm rest. The base is fixed on a foundation. The root portion of the first arm rest is hinged to the base through a pin. The root portion of the second arm rest is hinged to the top of the first arm rest through a pin. A display device is arranged at the top of the second arm rest. A first oil cylinder is arranged between the first arm rest and the base. The top of the first oil cylinder is connected with the first arm rest. The bottom of the first oil cylinder is connected with the base. A first connecting rod amplitude variation mechanism is arranged between the second arm rest and the first arm rest and is composed of a first connecting rod, a second connecting rod and a second oil cylinder. A second connecting rod amplitude variation mechanism is arranged between the second arm rest and the display device and is composed of a third connecting rod, a fourth connecting rod and a third oil cylinder. The positions and the gestures of the truss mechanism for performance can be changed randomly, and the truss mechanism is applicable to advertising and indoor and outdoor performance under various occasions.

Description

technical field [0001] The invention relates to a truss mechanism, in particular to a truss mechanism for display and performance. Background technique [0002] A truss refers to a planar or spatial structure composed of straight rods and generally having triangular units. Under load, the truss members mainly bear axial tension or pressure, so that the strength of the material can be fully utilized. When the span is large, it can save material, reduce self-weight and increase rigidity compared with solid web beams, so it is suitable for large spans. Load-bearing structures and high-rise structures, such as roof trusses, bridges, transmission line towers, satellite launch towers, hydraulic gates, crane frames, etc. [0003] The existing truss mechanisms used in common outdoor displays are generally fixed, such as outdoor billboards. Once installed, they cannot be adjusted, and the place of use is also limited. Contents of the invention [0004] The technical problem to be...
