Single-degree-of-freedom folding water tank

Abstract

The invention discloses a single-degree-of-freedom folding water tank. An inner film of the single-degree-of-freedom folding water tank disclosed by the invention is arranged in a framework; the framework comprises a front link mechanism, a rear link mechanism, a left link mechanism and a right link mechanism; each link mechanism comprises a link, a joint, a joint with a universal wheel, and a hinge joint; the links are mutually hinged by the hinge joints; each two adjacent link mechanisms are hinged by the corresponding joint and the corresponding joint with the universal wheel; and one end of a fixed pin rod is hinged with one joint, and the other end of the fixed pin rod is clamped with one joint at the same side. According to the single-degree-of-freedom folding water tank disclosed by the invention, the framework is a single-degree-of-freedom scissors-fork link mechanism, and the link mechanism is connected by the joints and the hinge joints. The link mechanism is locked through the single fixed pin rod after being unfolded. The joints with the universal wheels are arranged at the bottom of the link mechanism, and the water tank is movable as a whole. The inner film of the water tank covers in the framework after the framework is unfolded; and the water tank is capable of stretching simultaneously and shrinking simultaneously in a length direction and a width direction, that is, the length and the width of the water tank are reduced simultaneously, so that a high stretching-shrinking ratio is achieved.

Description

technical field [0001] The invention relates to a single-degree-of-freedom folding water tank, which belongs to the technical field of folding water tanks. Background technique [0002] The disadvantages of the existing folding water tanks mainly include: 1. The unfolding efficiency is low, or the height is reduced, or it is dismantled. 2. It needs the cooperation of a crane and multiple workers. 3. The expansion ratio is small. [0003] The patent number is ZL201320766032.3, the authorized announcement number is CN203845140U, and the authorized announcement date is September 24, 2014. The utility model patent named "foldable water tank" can only be reduced by disassembling the frame, although it can be greatly reduced during transportation. It saves space, but it is troublesome to disassemble and install. [0004] The patent number is ZL 201210133117.8, the authorized announcement number is CN102658926B, and the authorized announcement date is December 25, 2013. The inve...
