Problems solved by technology

[0005] Although the triangular truss can be folded, there are still the above problems, and the triangular truss is not as widely used as the square truss, and the splicing method of the triangular truss is also more complicated, not easy to produce, and more difficult to use

Embodiment Construction

[0088] In order to have a further understanding and understanding of the structural features and the achieved effects of the present invention, a detailed description is provided with preferred embodiments and accompanying drawings, as follows:

[0089] Due to the square four-tube truss, in the actual use process, especially when it is used as a beam that requires high strength, the force on the four sides of the truss is inconsistent, and often two of them are under great force. The force on the two surfaces is small, and in the actual use of the truss, one truss will not be used alone, and many trusses and square joints for connection are often used in combination with each other. Therefore, on the two faces with less stress, the active hinge link parts of the present invention are added to make it have the function of shrinking the volume of the truss. At the same time, multiple trusses and square joints are used together without affecting the overall truss The strength of ...

Abstract

The invention relates to a truss connection device, which comprises main pipes and hinged connecting rods, wherein the main pipes are connected by the hinged connecting rods; each hinged connecting rod comprises a first hinged component, a second hinged component, a steel pin and a circular tube respectively; the two ends of the circular tube are respectively connected with the second hinged component, and the second hinged component is in fit connection with the first hinged component by using the steel pin as an axis. The truss connection device of the invention has the advantages of simple and quick folding mode, reasonable stress, and capabilities of reducing much volume of the truss connection device subjected to folding and saving the expenses of the users for transportation, storage and the like; although the effect of folding can be achieved by using other methods, according to the folding principle of the truss connection device of the invention, a greater scale of volume reduction can be achieved, so that the use of the connection device is more convenient; and the truss connection device of the invention has an appearance extremely similar with the appearance of an original fixed truss, therefore, the truss connection device of the invention is also beautiful in appearance, thereby improving the use acceptance of the product.

Description

technical field [0001] The invention relates to the field of application of metal frames, such as stage light frames, display frames for exhibitions, and building structures, and in particular to a truss connecting device, which can realize functions such as folding and stretching of the truss. Background technique [0002] Existing straight trusses and curved trusses such as figure 1 , figure 2 shown. At present, the aluminum alloy truss is generally welded by four large main pipes and many small branch pipes. And steel pins to ensure quick and high-strength connections between trusses or trusses and square joints. [0003] Since the main pipe 100 and the branch pipe 200 are fixedly connected, they cannot be folded, and when doing surface treatment, the cost of logistics and surface treatment is relatively high, which is not as good as the folding truss described in the present invention. Small size, which is beneficial to save energy in production, etc., and figure 1...
