Abstract

The invention discloses a telescopic rod which comprises a movable rod, a guide sleeve, a pipe body and a bottom cover. Wherein the guide sleeve is embedded in the top of the pipe body; the bottom cover is arranged at the bottom of the pipe body; a cavity is formed in the pipe body, and a mixing agent is arranged in the cavity; the movable rod penetrates through the guide sleeve and is movably connected with the cavity; when the mixture expands with heat and contracts with cold, the movable rod is driven to linearly move back and forth relative to the pipe body, so that the telescopic function is realized; the mixing agent is prepared from the following components in percentage by mass: 0.3 to 0.8 percent of hexadecane, 7 to 8 percent of heptadecane, 37 to 42 percent of octadecane, 23.2 to 26 percent of nonadecane, 16 to 19 percent of twenty-alkane, 5 to 7.2 percent of heneicosane, 0.5 to 2 percent of docosane and 2 to 4 percent of C16-22 branched-chain alkane. The device has the advantages of being simple in structure, capable of automatically stretching and retracting and the like.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a telescopic rod and a window opener. Background technique [0002] Greenhouses, also known as greenhouses, can transmit light, keep warm (or heat), and are used to cultivate plants. In seasons that are not suitable for plant growth, it can provide a greenhouse growth period and increase production. It is mostly used for planting or raising seedlings of temperature-loving vegetables, flowers, forest trees and other plants in low temperature seasons. There are many types of greenhouses, which can be divided into many types according to different roof truss materials, lighting materials, shapes and heating conditions. [0003] The types of greenhouses include planting greenhouses, breeding greenhouses, exhibition greenhouses, experimental greenhouses, catering greenhouses, entertainment greenhouses, etc.; the design of greenhouse systems includes heating systems, heat preservati...
