Rain shed based on twisted spiral yarns

Abstract

The invention relates to a rain shed based on twisted spiral yarn, and belongs to the technical field of articles for daily use. The rain shed comprises a frame body, a first shielding assembly, a first pulling assembly, a second shielding assembly and a second pulling assembly, wherein the first shielding assembly is used for shielding rainwater, and the first shielding assembly is arranged on the frame body; the first pulling assembly is used for driving the first shielding assembly to expand, and the output end of the first pulling assembly is in transmission connection with the first shielding assembly; the second shielding assembly is used for shielding rainwater, and the second shielding assembly is arranged on the side edge of the frame body; and the second pulling assembly is usedfor driving the second shielding assembly to be unfolded, and the output end of the second pulling assembly is in transmission connection with the second shielding assembly. The rain shed is low in manufacturing cost, convenient to use and beneficial to popularization.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, and in particular relates to a canopy based on twisted helical yarns. Background technique [0002] In life, it is often encountered that clothes, food or other items are aired outside, but it rains suddenly, and people fail to rush back, resulting in the situation that the aired items are drenched by rain. [0003] At present, there are automatic retractable awnings, but most of these awnings require the use of humidity sensors, and involve complex circuits and transmission devices. The installation investment is large, which is not conducive to popularization. [0004] In recent years, scientific researchers have proposed a twisted helical yarn actuator (also called artificial muscle), which can be made from ordinary cotton yarn, wool yarn and other yarns through simple twisting, and the manufacturing cost is low. , conducive to promotion. The actuator can perform actions such as st...
