Specific embodiment
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now control attached drawing is described in detail
The specific embodiment of the present invention.
As Figure 1-Figure 8, foldable multifunctional tables and chairs of the present invention, including table top turnover mechanism, six bar contracting mechanisms,
Tables and chairs leg rotating shrinking mechanism, chair back ratchet and pawl arrangement, rotation clamping mechanism, aided drawing device.
Table top turnover mechanism includes ratchet thin plate 15, trough of belt baffle 14, pawl 16 and pin 17；Six bar contracting mechanisms include
Parallel four Bian Hang mechanisms and following click reduction supporting rod, parallelogram mechanism is by supporting 1, connecting under table frame 4, desktop
