Quick folding yurt with closed-chain connecting rod bracket

Abstract

The invention relates to a quick folding yurt with a closed-chain connecting rod bracket. A felt wall (6) is covered outside a connecting rod folding bracket (4) which is formed after connecting rods are hinged by hinged supports (3), a top cover (1) is arranged at the top of the yurt, windows and doors (5) are opened in the surface of the wall, and a pyramidal top slope (2) is arranged between the top cover (1) and the felt wall (6). According to the arrangement of a multiple-degree-of-freedom closed-chain multi-connecting rod folding mechanism, the center of gravity of the connecting rod folding mechanism is uniformly distributed at the lower position of the peripheral wall of the yurt, the complicated rotation torsion and the bending moment generated in the deformation process are absorbed by parts of the connecting rods through elastic components, so that the advantages of coordinated structure, no self-locking phenomenon, high compression strength, stable mechanism and convenience for the operation of folding or unfolding are achieved. After the complicated support functions of peripheral expansion and upward protruding are finished and the folding mechanism is folded, the yurt is small in volume and light in weight, but after the assembly of the yurt is finished, the yurt has the characteristics of large area, firmness, stabilization and convenience in carrying and transportation.

Description

technical field [0001] The present invention relates to international patent classification E04H folding tent or canopy technology or device, especially closed-chain connecting rod support fast folding yurt. Background technique [0002] In the prior art, folding or tent technology with a portable structure is generally only suitable for light and small tourist facilities, because the force strength of the general folding mechanism is limited. When it is necessary to manufacture larger blooms or tents, It can only be built in the traditional way. Although this meets the requirements for the firmness of the facility, it is time-consuming and laborious to build, and it is heavy, with a lot of materials, and the movement and dismantling are also complicated and cumbersome. At the same time, these tasks usually require the cooperation of multiple people to complete. [0003] In addition, because the known folding mechanism usually involves the application of the link mechanism, ...

AI Technical Summary

Problems solved by technology

Therefore, the planar link mechanism is widely used in various machinery and instruments; at the same time, the disadvantage of the link mechanism is: there is a gap in the lower pair, and a large number of lower pairs will cause motion accumulation errors; and its design is more complicated , it is not easy to accurately realize complex and regular movements

[0007] The above improved technologies such as these still have the disadvantages of poor structural stability due to the high center of gravity of the folding bracket caused by referring to the folding frame of the umbrella; or, the disassembly and assembly are still complicated and cumbersome.
