Shading box

Abstract

The invention discloses a shading box. The shading box comprises a box body; a containing cavity is formed in the box body; the box body is provided with an opening; a shading louver is arranged in the opening; the shading louver comprises transmission rods, shading nets, a transmission mechanism and positioning rods; the transmission mechanism comprises connecting rods and swing rods; each connecting rod comprises a first magnet and a second magnet, wherein one side surface, close to the second magnet, of the first magnet is a first clamping surface; one side surface, close to the first magnet, of the second magnet is a second clamping surface, and the first clamping surface and the second clamping surface attracts each other; the middle part of each swing rod is connected with one positioning rod through a first rotating shaft; and one end, away from one corresponding connecting rod, of each swing rod is connected with one transmission rod through a second rotating shaft. The shadingbox can provide a weak light environment condition for plant cultivation and meets requirements of ventilation and the like by plant cultivation, the use is very flexible, and practicability is higher.

Description

technical field [0001] The invention relates to a light shielding box. Background technique [0002] During some experiments in the laboratory, it is sometimes necessary to create a certain low-light environment for plants to simulate the long-term dark and dark environment in some areas in the actual production process, so as to facilitate the research on the resistance of plants under adversity. In addition, it is also necessary to keep the plants from affecting the ventilation and watering and fertilization in the weak light environment. Currently, most of the similar functions on the market are shading boxes, but the poor ventilation of shading boxes usually cannot be applied to the cultivation of plants, and there are some simple ones. The shading box of the present invention uses a shading net to surround the entire shading box, and places plants in the shading box, but the use of these shading boxes is not flexible, and it is difficult to achieve the purpose of simula...
