Description

Technical Field

[0001] The utility model relates to the technical field of insect-proof nets, in particular to a foldable skylight insect-proof net. Background Art

[0002] With the development of domestic agricultural facility technology, high-end greenhouses are being used more and more. Folding skylight insect-proof nets, as one of the supporting facilities of high-end greenhouses, have also been widely used. Greenhouses open windows for ventilation in high temperature seasons to reduce the temperature and humidity in the greenhouse; at the same time, they physically prevent various pests from entering the room to harm the growth of plants, thereby reducing the use of pesticides and ensuring the green safety of plants.

[0003] The Chinese patent application number 202220023000.3 discloses a side fan-shaped folding skylight insect-proof net, and discloses the following technical scheme: the skylight insect-proof net is installed on the side of the active surface of the skylight and the side of the corresponding window frame, and the skylight insect-proof net is a foldable protective net body, which is composed of a plurality of meshes connected and sewn to form a foldable protective net body, and the mesh is folded or unfolded along the suture line; the meshes on both sides of the protective net body are fixed mesh belts, which are fixed to the side of the active surface of the skylight and the side of the corresponding window frame by fixing adhesive strips; the length of the mesh on the protective net body increases stepwise from the middle to both sides, and the lower end of the mesh is a 45° cut angle. After the side of the semi-finished protective net body after connection is fully unfolded, an isosceles triangle fan-shaped notch structure should be formed at the lower end. The utility model has the advantages of automatic folding and convergence, flexible size adjustment, convenient installation and good sealing.

[0004] However, the current preparation process of the foldable skylight insect-proof net has problems: since the two top corners of each net unit in the preparation process are stacked and sewn up and down, the thickness of the net at these two top corners is twice as thick as the thickness of the other parts of the net. The thickness of the two top corners of the foldable skylight insect-proof net made by this process is twice as thick as the thickness of the net at other places. Therefore, after the skylight is closed in the low temperature season, the foldable skylight insect-proof net and the skylight frame will have the problem of not closing tightly, causing heat loss and energy loss; rubber sealing strips need to be installed later, which increases the later cost.

[0005] Therefore, a foldable skylight insect-proof net is designed to solve the above-mentioned technical problems. Utility Model Content
