Problems solved by technology

[0002] Usually, when there is a joint connection between two large-area plates, a hinge is required, and a certain dynamic system is required to undertake the force support and complete the stretching and folding actions. At the same time, the folding and stretching mechanism completes the two When the blocks are folded and stretched at 0-180 degrees, it takes up a lot of space and the mechanism is relatively complicated, which is not very suitable for many application environments.

Abstract

The invention discloses a folding and unfolding mechanism. The folding and unfolding mechanism is installed between an upper panel and a lower panel which are hinged and used for folding and unfolding the upper panel and the lower panel and completing overturning at 0-180 degrees between the upper panel and the lower panel. The folding and unfolding mechanism comprises a four-connection-rod assembly, a push rod assembly and an auxiliary connection rod assembly. The auxiliary connection rod assembly comprises a first auxiliary connection rod and a second auxiliary connection rod. One end of the first auxiliary connection rod is hinged to one end of the second auxiliary connection rod. The other end of the first auxiliary connection rod is hinged to the lower panel. The other end of the second auxiliary connection rod is fixedly connected with a fourth connection rod. An axial locking mechanism is added, the included angle relative to the axis of an oil cylinder is locked after a start skid acts to the preset position, the start skid produces no relative rotation, the relative structure is simple, and maintenance is convenient.

Description

technical field [0001] The invention relates to the technical field of a hinged auxiliary structure of a plate, in particular to a folding and stretching mechanism. Background technique [0002] Under normal circumstances, when there is a joint connection between two large-area plates, a hinge needs to be used, and a certain power system is required to bear the force support and complete the stretching and folding actions. When the blocks are folded and stretched at 0-180 degrees, the space occupied is relatively large, and the mechanism is relatively complicated, which is not suitable for many application environments. Therefore, there is a need for a folding and extending mechanism with a simple overall structure and a small footprint, as well as addressing the above-mentioned problems. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned problems, an object of the present invention is to provide a folding and stretching mechanism. [0004] In order to achi...
