The invention discloses a linkage device for unfolding and folding a foldable carriage. The linkage device comprises a connecting rod, a right-hand thread nut, a left-hand thread nut, a positioning pin and a right-hand and left-hand thread screw rod. The right-hand and left-hand thread screw rod is characterized in that one half of the left-hand and right-hand thread screw rod is of a right-hand thread, and the other half of the left-hand and right-hand thread screw rod is of a left-hand thread; a right-hand thread nut is arranged at the right-hand thread end of the right-hand and left-hand thread screw rod; a left-hand thread nut is arranged at the left-hand thread end of the left-hand and right-hand thread screw rod, the left-hand thread nut is connected with one end of the connecting rod through the positioning pin, the other end of the connecting rod is connected with a carriage plate, the left-hand thread nut is connected with one end of the connecting rod through the positioningpin, and the other end of the connecting rod is connected with the carriage plate; the linkage device is small in occupied effective space, simple in structure, firm, reliable, easy to operate, capable of being manually and electrically operated and capable of being maintained by ordinary people.
Description
technical field [0001] The invention relates to a folding car body and a folding carriage, in particular to a linkage device for unfolding and folding a folding carriage. Background technique [0002] With the development of the times and the improvement of people's living standards, mobile folding board houses and folding carriages have appeared on the market. The unfolding and folding devices use electric push rods or hydraulic equipment. The devices cannot be used manually. They can only be removed and then used. Manual operation takes up a lot of effective space. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and propose a linkage device for unfolding and folding of a folding carriage, which is reasonable in design, simple in structure, can be operated manually or electrically, and is easy to maintain. [0004] The technical solution adopted by the present invention to achieve t...
